The utility of fcience, and the delight which it affords to the human mind, are ac¬ knowledged by every man who is not immerfed in the groffeft ignorance. It is to the philofopher that the hulbandman, the archite£t, the carpenter, and the feaman, &c. are indebted for the principles of thofe arts, by which they furnifh us with moft of the accommodation^ and with all the elegances, of civilized life ; whilft the pleafure experienced in the very progrefs of philofophical refearch is fuch, as both reafon and revelation intimate, not obfcurely, will conftitute part of our happinefs in a future date. Small, however, would be the attainments of any man in fcience, were they confined within the limits of his own refearches. Our knowledge of corporeal nature originates in thofe perceptions which we have by the organs of fenfe; and which, treafured up in the memory, we can, by the powers of reafon and imagination, varioufly modify, ar¬ range, and combine, fo as from a number of particular truths to form to ourfelves ge¬ neral principles. But thefe principles would be few indeed, had each individual no other materials of which to form them than the perceptions furnilhed immediately by his own fenfesw It has long been a matter of general regret, that the progrefs of fcience has been flow and laborious ; but it never could have commenced, or could have only commenced, were every man obliged to begin his career from his own fenfations, with¬ out availing himfelf of the difcoveries of others who have travelled over the fame ground before him. To this narrow field, however, philofophical inveftigation is not confined. By means of the arts of writing and drawing, the difcoveries of one individual may be made acceflible to another, and the fcience of every age and of every country treafu' red up for the ufe of ages and countries the moft remote. Hence arifes the utility of what is generally called literature, or the knowledge of the languages, cuftoms, and manners, wrhich have prevailed among the various nations of the earth. Without this knowledge the fcience of the ancients would be locked up from the moderns j and even the difcoveries of modern nations would be inacceflible to each other. With all the aid which can be furnifhed by one age or nation to another, the la¬ bours of the philofopher-ftill prefent themfelves as immenfe and difficult. His objedfc comprehends univerfal nature, of which nothing can be known but by fenfation and refledtion ; but the objedts of fenfe are all individuals, almoft infinite in number, and for ever changing : fo that inftead of a fyftem of fcience, the firft view of the corporeal, world woifld lead us to imagine, that from our moft diligent refearches nothing could be obtained but a vaft collection of particular truths. Such a collection, whilft it would burden the memory, could be of little advantage to-the arts of life ; for we are- very feklom brought, on different occafions, into circumftances fo perfedtly ftmilar, as to require, without the ftnalleft variation, the fame condudt.. But VI PREFACE. But though all the objecls offenfe, of memory, and of confcioufnefs, are unqueftion- ably individuals diftinct from each other, the contemplative mind of man obferves among them various refembiances and analogies. It obferves, that the fenfation com¬ municated to the fight by fnow is fimilar to that communicated by milk, paper, chalk, and a thoufand other objeds; that all external obj'eds are folid, extended, divifible, and of fome figure ; that the path defcribed by a planet round the fun refembles that defcribed by a cannon ball over the furface of the earth ; and that many of the adions of brutes are fimilar to thofe which we are impelled to perform by the internal feelings of delire and averfion. This view of nature, quiefcent andadive, fuggefted to the philofopher the expedi¬ ency of ftudying the vaft multitude of objeds which compofe the univerfe ; not indi¬ vidually, but in groups clafled together according to their perceived refembiances or analogies. He faw that his labour would thus be at Once fhortened and rendered ini finitely more ufeful; but he likewife faw, or ought to have feen, that it would by no means be taken wholly away. Much cautious attention is requifite to clafs objeds in human fyftems as they are in fad clafied in the fyftem of nature. Analogies are a|)t to be miftaken for refembiances ; a refemblance in a few particulars for a refemblance in all; and events, which have in reality very little in common, to be attributed to the fame or to fimilar caufes. ■ Tbefe' miliakes can be avoided only by a painful in- dudion of fads, by means of experiments accurately made on individual objeds ; and it was but very lately that indudion was employed as the inftrument of fcientific re- fearch. In ancient Greece, where philofophy firft afiumed a fyftematie form, all the objeds of human thought were ranged under ten categories or predicaments ; and every thing which could be affirmed or denied of thefe categories was fuppofed to be com¬ prehended under five clafles called predicables. Among the Greek philofophers, therefore, the ufe of indudion was to alcertain the category to which any particular objed belonged ; after which, nothing more was to be done but, by a fhort procefs of fyllogiftic reafoning, to affirm or deny of that objed whatever could be affirmed or denied of its category. To this ancient arrangement of human knowledge many infuperable objedions have been urged. But it mull be confeffed, that the arrangements which have been propo- fed in its Head, by the fages of modern times, have little claim, to.greater perfedion. Locke clafled all things under three categories; substances, modes, and ideas. Hume reduced the number to two; impressions and ideas. The former of thefe philofophers admitted of only four predicables, all different from thofe of the ancients; the latter at firil extended the number to feven, but afterwards reduced it to three ; among which none of the ancient predicables are to be found, and only one of thofe which had been admitted by Locke. These different clafiifications of knowledge are the natural confequences of mens at¬ tempting what the greateil powers of the human intelled will never be able to accom- plilh. It certainly was the aim of Arillotle, or'whoever was the inventor of the categories and the,predicables, to delineate the whole region of human knowledge, actual and poffible -, to point out the limits of every diltridt ; and to affign to every thing which can be'the objedl of human thought its proper place in the vail; arrangement. Such an attempt evinces the ambition of its author ; nor has the ambition been much lefs of fome of thofe by whom the rail] arrogance of the Stagyrite has been moil feverely eenfured. Locke fays exprefsly, that as the objedis of our knowledge are confined to fubflances, modes, -Ai\(\ ideas, fo we can difcover nothing of thefe, but, ijl, their identity or divcrfiiy; zd, their relation ; 3d, their co exiflence or nec.effhry connection ; and, ytb, their real exigence: while Hume declares, with fome hefitation indeed, that we can know nothing hut the refeniblance, contiguity in time or place, and caufation of our im- preffions and ideas. These F REF A C E. These attempts, as well modern as ancient, to contract the whole furniture of the human mind into the compafs of a nut-fhell, and to give at once a complete chart-of knowledge, have been cenfured, not only as prefumptuous, but as the fertile fources of error, by a philofopher whofe writings do honour to this age and nation. “ To make a perfect divilion (fays Dr Reid), a man muft have a perfect comprehenfion of the whole fubje£t at one view. When our knowledge of the fnbjeCt is imperfed, any divifton we can make riiuft be like the firlt Iketch of a painter, to be extended, con- traded, or mended, as the fubjed fhail be found to require. Yet nothing-is more common, not only among the ancient1 but even among1 modern philofophers, than ta draw from their incomplete diviltons, conclufiom which- fuppofe them to be perfed. A divifion is a repofitory which the- philofopher frames for holding his ware in con¬ venient order. The philofopher maintains, that fuch or fuch a thing is not good ware, becaufe there is no place in his ware-room that fits it. We are apt to yield to this argument in philofophy, but it would appear ridiculous in any other traffic.” The truth of thefe obfervations will be controverted by no man who s not an abfo- lute ftranger to the various fyflems, ancient' and modern, of what has been called the JirJl philofophy. Bu r if every fcientific arrangement of knowledge which has hitherto been propofed be fo very imperfed, what judgment are we to form of that which is adopted by the compilers of Didionaries or Encyclopaedias, in which the arts and fciences are arranged according to the order of the alphabet, and A, B, C, &c. confidered as the categoriesi The author whom we have juft quoted affirms, that of all methods of arrangement this is the molt antiphilofophical ; and if he allude only to fuch Encyclopaedias as are mere didionaries, in which the feveral arts and fciences are broken into fragments, Scattered through the work according as the alphabet has happened to difpofe of the various- technical terms which have place in each, his affertion is unqueftionably true. Its truth is indeed admitted by Chambers himfelf, the compiler of one of the firft and moft. valuable of thefe didionaries, who fpeaks of the works of his predeceffors as containing, nothing but a multitude of materials, or a confufed heap of incoherent parts. “ For¬ mer lexicographers (fays he) fcarce attempted any thing like ftrudure in their works they feem not to have been aware that a didiorjary is in fome meafure capable of the advantages of a continued difcourfe : and hence it is, that we fee nothing like a whole- in what they have done.” Proposing to remedy thisdefed in his own Didionary of Arts and Sciences, he in¬ forms us, that “ his view was to conlider the feveral matters, not only in themfelvesr but relatively, or as they refped each other; both to treat them as fo many wholes, and as fo many parts of fome greater whole ; and to point out their connedion with each other, and wi.h that whole, by reference : fo that by a courfe of references from gene¬ rals to particulars, from premifes to conclufions, from caufe to effed, and vice verfa, a communication might be opened between the feveral parts of the work, and the de¬ tached articles be in fome meafure replaced in the natural order of fcience, out of which the alphabetical order had removed them.” To enable the reader with the greater eafe to replace in the order of fcience the various articles fcattered through the didionary, he furniftied him in the preface with what muft be confidered as an elegant analyfis of human knowledge; by which may be feen, atone view, the mutual dependence of the feveral parts upon each other, and the intimate connedion of the v/hole. But though the found judgment of Mr Chambers thus direded him to make the ar¬ rangement of his Cyclopaedia vaftly preferable to that of any work of the fame kind which had been publiftied before it; we, are afraid that, in its original form, it was- ftill liable to the objedions of Dr Reid. Had all the articles in the work been treated in fufficient detail to conftitute, when reunited in the order of Icience, fo many com¬ plete fyftems ; yet the multitude of references was fo great, that'this reunion could not have been made but by a degree of irkfome labour* to which few readers will ever fub- KNOWLEDGE is either viii PREFACE. ittit (A)* The work therefore, with all its improvements, was Hill a book of Ihreds and patches, rather than a feientific di&ionary of arts and fciences; and conlidering the letters of the alphabet as the categories, the arrangement was certainly inconve¬ nient as well as antiphilofophtcal. Of this inconveniency, infeparable from a mere didlionary of arts and fciences, the original Compilers of the' Encyclopaedia Britannica were fully aware; and they refolved to conflrudl their own Work upon a plan from which it might be completely removed. They were equally apprifed with their predecelfors of the utility of explaining by it- felf every technical term, and of illuftrating every particular topic, in the wide circle of the arts and fciences; but they were at the fame time fenfible, that it is only by thinking in method, and reducing their ideas to the order of nature, that mankind can make (a) To be convinced of the truth of this afiertion, one needs but to caft his eye over the author's table of arrangement, it is as follows. f Meteorology.

(Fis Such PREFACE. m make any progrefs in ufeful knowledge. To accomplilh therefore effedlually what Mr Chambers by means of his prefatory fcientifical analyfis attempted in vain, they endea¬ voured to give a compendious, yet clear and fatisfa&ory, account of the feveral arts and fciences under their proper denominations, whilft the fubordinate articles in each were likewife explained under their technical terms. Thefe fubordinate articles they divided into three kinds ; of which the firft confifts of fuch as, independent of particu¬ lar fyftems, admit of a full and complete illuftration under their proper names ^ the fecond, of fuch as require to be partly difcufled under the fyftems to which they belong, and partly under their own denominations ; and the third, of fuch as apper¬ tain to fyftems of which all the parts rnnft be elucidated together. Articles of the firlf kind admit of no references; thofe of the fecond, being only partially explained under their proper denominations, demand references to the fyftems where the illuftrations are completed ; and thofe of the laft are wholly referred to the fyftems of which they are conftituents. Such has been the arrangement of the Arts and Sciences in every edition of the n- eyclopasdia Eritannica ; and it furely falls not under that cenfure which Dr Rei pro¬ nounced with juftice on many other works bearing a fimilar title. In the fpirit of true philofophy, that great man obferves, that the fame fubjeft may admit, and even require, various divifions, according to the different points of view from which it is contemplated ; and we doubt not but, if he had been alked, he would candidly have acknowledged, that the divifions and arrangement of the Encyclopaedia Britannica are calculated to anfwer every purpofe which can be expe&ed from a gene¬ ral repofitory of arts, fciences, and mifcellaneous literature. They are fuch as muft give to readers of every defeription the moft eafy accefs to the objeds of their purfuit: for whilft the philofopher or fyftematic artift may be fully and regularly informed by turning to the general name of the fcience or art which he wifties to explore, the man who has occafion to confult only particular topics will find them illuftrated under the terms by which they are denominated. Contemplated from this point of view, the arrangement of the Encyclopaedia Britannica needs not fhrink from a comparifon even with that of the Encyc/opedie Metbodique j for though that voluminous work, confiding of a dictionary of dictionaries, may have the appearance of being more fyftematically arranged ; yet we, who have had occafion to confult it frequently, have never found our objeCt the more readily for having been obliged to travel in queft of it through different alphabets. A dictionary, in which the feveral arts and fciences are digefted into diftinCt trea¬ ties or fyftems, whilft the various detached parts of knowledge a e explained in the order of the alphabet, feems indeed to have received the beft form of which fuch a work is fufceptible ; and may certainly be made to anfwer one end, which more philofophical arrangements never can accomplilb. Under the various letters of the alphabet, it is obvious that the whole circle of the feienoes may be completely exhaufted; and that every difeovery, ancient or recent, may be referred to the particular fyftem which it Vol. I. Bart I. b tends Such'is that great and general analyfis of knowledge, which-has by fonie of our correfpondents been recom¬ mended to us in terms of the higheft praife, and to which elegance and accuracy cannot perhaps be refufed. Its utility, however, as prefixed to a diftionary of arts and'fciences, is not very apparent. From each word, which in this table is printed in capitals, many branches are made to fpring, which in the dictionary are all treated as feparate articles. Thus from Meteorology we are referred, in a fubordinate analyfis, to Air and the Atmosphere ; including, rft, ’ he hiftory of its contents, ./Ether, Fire, Vapour, Exhalation, &c. 2d, Meteors formed therein; as Cloud, Rain, Shower, Drop, Snow, Hail, Dew, Damp, &c. Rainbow, Parhelion, Ha¬ lo, Thunder, Waterspout, &c. Winds, Monsoon, Hurricane, and the like. As every word printed in capitals, as well in this fubordinate divifron as in the general table, is the title of an article treated feparately in the Cyclopaedia, we muft. turn backwards and forwards through more than 24 references before we come at the detached topics, which we are directed to unite into a fyftem of Meteorology. The number of articles which muft be united in the fame manner to conftitute the Compiler’s fyftem of Metaphysics is upwards of 4$ ; and thofe which are referred to Theology above 300 ! PREFACE. tends ter confute or to confirm, without having recourfe to the awkward expedient of employing feveral alphabets, or the ftill more inconvenient arrangement by which the fyftems themfelves are broken into fragments. But on this topic it is needlefs to expatiate. The very favourable reception with which the two former editions of the Encyclopaedia Britannica wrere honoured by the Public ; the ftill greater encouragement which has been given to the prefent; and the adoption of the plan by the editors of other repofitories of arts and fciences—bear ample teftimony to the excellence of the arrangement. On this fubjedt we exprefs ourfelves with the greater eafe and the greater confidence, that we cannot be accufed of flattering our own vanity, or publiftiing our own praifes; for the merit of forming the arrange¬ ment, as well as of introducing into the Work various branches of knowledge, from which, as they are not generally to be found in dictionaries, it derives a juft claim to the favour of the Public, belongs not to the Compilers of the prefent Edition. After furveying any particular art or fcience, our curiofity is excited to acquire fome knowledge of the private hiftory of thofe eminent perfons by whom it w7as invented, or has been cultivated and improved. To gratify this curiofity, thofe who formed the plan of the Encyclopaedia Britannica refolved to enrich it with a department not to be found in any prior colledtion of the fame kind except the French Encyclopedic. Of all the various fpecies of narrative-writing, it is acknowledged that none is more worthy of cultivation than biography ; lince none can be more delightful or more ufeful, none can more certainly enchain the heart by irrefiftible intereft, or more widely diffufe inftrudlion to every diverfity of condition. Its tendency to illuftrate particular paflages in general hiftory, and to diffufe new light through fuch arts and fciences as were cultivated by the perfons whofe lives are related, are fads too obvious to require proof. It exhibits likewife the human charader in every poffible form and fituation. It not only attends the hero through all the buftie of public life, but pur- fues him to his moft fequeftered retirements. It fhows how diftinguiftied charaders have been involved in misfortunes and difficulties ; by what means they were extrica¬ ted ; or with what degree of fortitude and dignity they difeharged the various func¬ tions, or fuftained the viciffitudes, fometimes profperous and fometimes adverfe, of a checquered and a fluduating life. In fuch narratives men of all ranks muft feel them¬ felves interefted ; for the high and the low, as they have the fame faculties and the fame fenfes, have no lefs firnilitude in their pains and pleafures ; and therefore in the page of honeft biography, thofe whom fortune or nature has placed at the greateft dif- tance, may mutually afford inftrudion to each other. For thefe reafons it is, that every man of learning and tafte has efteemed the biographical labours of Plutarch among the moft valuable and interefting remains of antiquity. The lives and charaders, therefore, of fuch perfons as have excelled in the arts either of war or of peace, of fuch as have diftinguiffied themfelves either on the theatre of adion or in the recefs of contemplation, will be found in the Encyclopaedia Bri¬ tannica alphabetically difpofed under their proper names. Many indeed are omitted, for whom the reader wdll naturally look ; fome becaufe, in the order of the alphabet, we had pafled the initial letters of their names before v’e had intelligence of their deaths; others, through the inadvertency, whether excufable or not, of the Editors ; feveral, for a reafon which fhall be afterwards affigned for omiffions of a different kind, and perhaps of greater importance; and a very few from the contemptuous re- fufal of their friends to anfwer the Editor’s letters refpedfully requefting the neceffary information (b). But (b) Of this treatment we have not indeed often had occafion to complain. While men of the firft eminence in church and Itate have readily anfwered the letters that were addreffed to them, and either communicated the PREFACE. xi But while one part of our readers will regret that we have given no account of their favourite philofopher, hero, or ftatefman, others may be difpofed to remark, that we have dragged from obfcurity the names of many perfons who were no proper objeds- of fuch public regard. Tothefe we can only reply, that, with the greateft biographer of modern times, we have long thought that there has rarely paffed a life of which a faithful narrative would not be ufeful; and that in the lives of the molt obfcure per¬ fons, of whom we have given any account, we faw fomething either conneded with recent difcoveries and public affairs, or which we thought capable of affording a leffon to great multitudes in fimilar circumftances. Between eminent atchievements and the fcenes where they were performed, there is a natural and neceffary connedion. The charader of the warrior is conneded with the fields of his battles ; that of the leglflator, with the countries which he civilized ; and that of the traveller and navigator, with the regions which they explored. Even when we read of the perfons by whom, and the occafions on which, any particular ]branch of knowledge has been improved, we naturally wifh to know fomething of the places where fuch improvements were made. This curiofity, fo natural and fa laudable, has been frequently felt by ourfelves during the compilation of this- Work j and to gratify it in others, we have fubjoined to the name of every confiderable place an account of its fituation, its climate, its foil, its peculiarities, its inhabitants, with their manners, cultoms, and arts; its revolutions, laws, and government, with what¬ ever elfe appeared neceffary for the reader’s information, and at the fame time admif- fible into a Work of fuch variety and extent. It is indeed probable, that by many of our readers we lhall be thought to have done too much rather than too' little in this department; and to have filled our pages with accounts of towns and villages not of fufficient importance to demand general attention. But were it known, how many of fuch places we have excluded from our Work, though recommended to us by fome of our moft obliging correfpondents, thofe who refled upon the different taftes of man¬ kind, and confider that we wrote for the Public at large, would forgive us for having occafionally employed a few fentences in the defcription of others, which^ whatever be their real importance, could not have been omitted without difappointing a very nu¬ merous clafs of readers. The knowledge of hiftory is fo important, not only to the flatefman and the legifla- tor, to whom indeed it is abfolutely neceffary, but likewife to every man who moves in a fphere above that of the lowed vulgar, that a Work profeffing to be a general re- pofitory of arts, fcienees, and literature, would be exceedingly defedive, if it did not contain fome information of the tranfadions of thofe who have been in poffeffion of the world before us ; of the various revolutions of ftates and empires and of all the other means which have contributed to bring every thing into the date in which we behold it. Fully aware of this, the Compilers of the Encyclopaedia Britannica, befides-giving a general view of univerfal hiftory and chronology, have enriched this edition with a fliort, though they hope luminous, detail of the progrefs of each particular nation* which from the remoteft period to the prefent time has aded a confpicuous part on the theatre of the world. The reader therefore will here find a very comprehendve view of Civil History, ancient and modern, in all its branches. Nor have the hifto- ries of Nature and Religion been negleded. Of the former, it is not perhaps too much to fay, that in all the fubdivifions of its three great kingdoms, it will be found more fully, more accurately, and more fcientifically, detailed in this Work than in any other didionary which has yet been publifhed. Of the latter, a brief view is given under the general article History ; the unavoidable defeds of which are in a. great meafure b 2. fupplied: information which was requefted, or politely affigned reafons for wifhing the lives of their friends not to be pub. Milled in the Encyclopaedia Britannica, the Editor recollefts but two men who maintained a fallen filence $ and thefe he cannot confider as moving in a fphere much higher than his own. P R £ £ A C t. ifcfi fupplied by the accounts that will be found, under their proper denominations, of all the confiderable fedls and opinions which have prevailed in the religious world from the earlieft periods to the prefent day. Such was the plan of the fecond edition of the Encyclopaedia Britannica; to which, as it feems hardly capable of improvement, the Compilers of the third have, with a few flight variations, ftri&ly adhered. Still, however, there was ample room for the efforts of all their induftry and all their learning; for the rapid progrefs of the phyfi- cal fciences had rendered the labours of their predeceflbrs in many departments ui'elels. Befides the introdu&ion of fome thoufands of new articles, there are not many of great importance, thofe in biography and geography alone excepted, which Hand in this Edition as they flood in the laft. Such recent difcoveries as could be introduced, have been mentioned with reference to their proper authors ; and, while the feveral fciences have been treated more fully and fyftematically, greater care has been employed to trace the hiftory of each from its firft invention, and to apply them all to the arts of life. To accomplifh a talk fo arduous and fo important, neither labour nor expence has been fpared. Literary journals; the memoirs and tranfa&ions of philofophic focieties; and all the moft valuable didlionaries of arts and fciences, both in our own and in other languages, have been conftantly confulted. The works of the moft eminent au¬ thors, as well ancient as modern, who have written on any particular art or fcience, have been colledted and compared. Such of them as treat of topics, about which there is no room for controverfy, and are at the fame time fufceptible of abridgement, have been abridged with the greateft care j whilft others, more concife and tenacious of their fubje£ts, have been more clofely purfued and more faithfully retained. Upon thofe branches of fcience on which the works of other authors furniihed nothing lit for the purpofe of the Editors, original eflays and treatifes are inferted, which were compofed either by themfelves, or by fuch of their friends as they knew to be intimately ac¬ quainted with the fubjedt. On difputed points, whether in the phyfical or moral fciences, arguments and objedions have been difplayed in their full force ; and of each of the various feds into which the Chriftian church is divided, the account is generally given by the moft eminent clergyman of that fed to whom the Editors could find ac- cefs. After the utmoft exertions, however, of our attention and induftry, wre are fenfible, perhaps more fenfible than any of our readers, that the Work palfes from our hands in a ftate far from perfedion; and that the man who ftiall not difcover in the Encyclo¬ paedia Britannica miftakes, needlefs repetitions, and even culpable omiflions, will bring to the examination of it no great flock of general knowledge. But for thefe offences the Editors perhaps need.no other apology than what will be furnifhed by the nature of the Work and the hiftory of its publication. In a colledion fo extenfive and multifarious, a few miftakes, repetitions, and omif- fions, might furely be pafled over without feverity of cenfure, although the publication had from the beginning to the end been fuperintended by the fame man ; but they will be allowed to have been almoft unavoidable, when it is known that, after the Work u^as far advanced, it was committed to the care of a new Editor, who, though he was in a great degree a ftranger to the contents of the printed volumes, found no clue of his predecelfor’s which could guide him accurately through thofe to be com¬ piled. We beg it to be underftood, that this obfervation is not made with a view to re¬ move any fhare of blame from the fecond to the firft Editor ; for Mr Colin Macfar- quhar, who conduced the publication beyond the middle of the twelfth volume, . was a man whom few who knew him will be difpofed to blame, and on whofe indu- ftrious integrity thofe who knew him beft muft admit that it would be difficult to beftow too much praife. Born in Edinburgh of parents refpedtable, though not afflu¬ ent, he was, at an early period of life, bound an apprentice to a printer. This pro- feflion gave him a tafte for fcience and literature, or rather furniihed him with oppor¬ tunities PREFACE; xiii tunities of cultivating the tafte which he derived from nature ; and he foon became well acquainted with the moft popular writers in natural hiftory and in natural and moral philofophy. When he opened a printing-houfe of his own, redtitude of condudl quickly recommended him to friends and to employment ; and the unremitted profe- cution of his ftudies eminently qualified him for fuperintending the publication of a new didtionary of arts, fciences, and literature*, of which, under the title of Encyclopaedia Britannica, the idea had been conceived by him and his friend Mr Andrew Bell en¬ graver. By whom thefe gentlemen were affifted in digefting the plan which attradled to that Work fo much of the public attention, or whether they had any afliftance, are queftions in which our readers cannot be interefted. Suffice it to fay, that Mr Mac- farquhar had the foie care of compiling the prefent Edition ; and that, with the aid of a very few literary friends, he brought it down to the article Mysteries, in the twelfth volume, when he was cut off in the 48th year of his age by a death which, though not hidden, was perhaps unexpedted. His career was indeed Ihort; but of him it may be faid with as much propriety as of moft men. Nemo parum diu vixit, qui •virtutis perfect (E perfect 0 fun El us eft munere. Among his literary correfpondents was the Reverend Dr Gleig of Stirling, who had written for him various articles, of which fome were publilhed during his lifetime and others in their order after his death. Thefe fhall be afterwards enumerated with thofe furnilhed by other occafional contributors; but they are mentioned at prefent, becaufe they account for that partial regard of Mr Macfarquhar for their author, which, on the death of the former, induced the truftees for his children, together with Mr Bell the furviving partner, to requeft the latter to undertake the talk which their deceafed friend had hitherto difcharged with fo much credit to himfelf. In this propofal, after fome hefitation on account of his diltance from Edinburgh, Dr Gleig acquiefced; but when he entered on his new office, he found matters in a ftate of no little confufion. Mr Macfarquhar, though his death had not been long expedted, had laboured long under a complication of difeafes ; the confequence of which was, that the materials which he had prepared for the prefs were almoll exhaufted ; and of thofe which were firft called for, fome had not paired through his corredling hand. This circumftance may perhaps account for fome defedts and inaccuracies in that part of the Work, to which the fecond Editor looks back with the leaft fatisfadtion ; but that which mull be his apology forfeverai repetitions and omiffions, was the negledt of his predeceffor during his lalt illnefs to make an intelligible index to his own labours. From the want of fuch a neceflary guide. Dr Gleig was perpetually liable, notwith- ftanding his utmoft circumfpedtion, to give under one title an explanation of fubjedts which had been before explained under another; and to omit articles altogether, from a perfuafion that they had been dilcuffed in fome preceding volume under the general fyftem to which they belong. Neither his repetitions nor omifiions, however, are Co many as fome have fuppo- fed them; for what has been haftily cenfured as a repetition, is frequently nothing more than the neceffary refumption of fome important fubjedt. Availing himfelf of the excellence of the plan upon which the Encyclopaedia Britannica is conltrudt- ed, he took the opportunity, when he found any 1'yltem fuperficially treated, to fupply its defedts under ibrne of the detached articles belonging to it. Of this he lhall men¬ tion as one inftance Hydrostatics ; which, confidered as a fyftem, muft be con- feffed to be defective ; but he truits that its defedts are in a great meafure fupplied un¬ der the feparate articles Resistance of Fluids, River, Specific Gravity, and IVater- Works. That in the Encyclopaedia Britannica no account is given of fome things which fhould have a place in a general repofitory of arts, fciences, and mifcellaneous litera¬ ture, muft be acknowledged ; but it muft likewife be acknowledged that fuch omifiions are neither numerous nor very important; for many fubjedts, which have been fup- pofed to be omitted, are treated under titles different from thofe under which they have PREFACE. siv have been looked for. Thus the method of calculating compound interefts, which one of our correfpondents cannot find in our Work, is taught in the article Algebra ; that of coating mirrors, of which another complains that no account is given, will be found under the term Foliating; and though it may be true, according to the peevifh remark of a third, that the reader is nowhere diredtly inftrudled how to grind optical glafles, yet if he read the article Glass-GnWm^, and underftand the dodtrine oflenfes as laid down in the article Optics, he will eafily, if an artift, difcover a method of performing that operation for himfelf. . , Omissions, however, there are towards the end of the Work; not the confequence of careleffnefs, but the offspring of necefiity. In an addrefs to the Purchafers of the Encyclopaedia Britannica, fubjoined to the ninth volume, the proprietors gave a rafti promife to comprehend the whole of their undertaking within the limits of eighteen ; and if intervening difcoveries fliould make it neceffary, to enlarge the laft volumes in quantity without any additional charge to Subfhribers. That the promife was raft), a moment’s refle&ion ftiould have taught them ; for in the prefent rapid progrefs of phyfical fcience, when new difcoveries are daily made, it was obvioufly impoflible, at fo earfy a period, to afcertain with precifion how many vo¬ lumes would be neceflary to bring a Work of fuch comprehenfive variety to theutmoft perfedion of which it is capable. This was indeed foon difcovered ; but the proprie¬ tors ftirunk not from their engagement, which they determined to fulfil to the- utmoft extent of its meaning, till the additional tax, which in 1795 was laid upon paper, in¬ volved them in difficulties which they had not forefeen. By the ad of parliament they w7ere indeed authorifed to reirnburfe themfelves by railing the fubfcription-price of their volumes; but they chofe rather to fubmit to a diminution of profit, than to take even a legal advantage of that Public by which they had hitherto been fo generoufly fupported. To complete their plan, however, in its original extent, was now impoffible, with¬ out a violation of the facred duties which they owe to themfelves and to their families. In this dilemma the Editor propofed that they ffiould ftate the cafe to their Subfcri- bers, of whom he is confident that nine-tenths would have releafed them from the obliga¬ tion of their promife : but after long deliberation, they judged that it would be more acceptable to the Public at large to comprehend the Work in the propofed number of volumes, though they ffiould exclude from the laft fuch articles as might be omitted without injury to fcience or the arts of life. If by any of their readers they ftiall be thought to have erred in this judgment, let them not, however, be too feverely bla¬ med ; for they have done much to adhere to the fpirit of their promife; and, in the large addition made to the bulk of the laft volume, have fhewn that they prefer their honour to their intereft. Several things have indeed been excluded ; but except fuch recent difr coveries as could not be noticed under the laft letters of the alphabet, it is believed that very little has been omitted which can be confidered as of great or general importance. At any rate, the Editor flatters himfelf, that the laft fix volumes of the Encyclopaedia Britannica do. not difgrace thofe by which they are preceded, and that the whole will bear to be compared with any other Work of the fame kind extant. Imperfed it cer¬ tainly is: “ but if much has been omitted, let it be remembered that much has like- wife been performed ;” that perfe&ion is not to be looked for in the works of man ^ and that every compilation of fuch variety and extent ffiould be examined with the fpirit which actuated one of the greateft critics of antiquity when perufing the works of his brother poets V°rum ubiplura nitent in car mine y non ego paucis Qffendar maculis, quas aut incuria fudit, - /iut humanaparum cavil natura. Hor. he art. poet. We PREFACE. We mentioned our obligations to occafional contributors; and many of our corre* Ipondents have exprefled an earned delire to know who thefe contributors have been. As there can be no impropriety in gratifying fuch a delire, we lhall cdnclude this Pre¬ face, by afligning the various articles, not compiled by the Editors themfelves, to their refpedtive authors : but as many of the writers for the fird twelve volumes were known to Mr Macfarquhar alone, they will not attribute the omidion of their names to cul¬ pable dedgn, but to irremediable ignorance. For whatever indnudion may be conveyed in the articles Anatomy and S(jrgery the Public is indebted to Andrew Bell, F. S. S. A. one of the proprietors, and the in¬ genious Mr Fyfe. From the former of thefe gentlemen the world will foon receive one of the mod fplendid anatomical works which it has yet feen ; and as the latter has long officiated under Dr Monro as didedlor in the anatomical fchool of the univerfity of Edinburgh, it is needlefs for us to fay how well he mud be acquainted with the fubjedts on which We employed him to write. Aerology, Aerostation, Chemi¬ stry, Electricity, Gunnery, Hydrostatics, Mechanics, Meteorology, with mod of the feparate articles in the various branches of natural hidory, we have reafoix to believe were compiled by Mr James Tytler chemid ; a man who, though his con¬ duct has been marked by almod perpetual imprudence, podedes no common diare of fcience and genius. The article Blind was furnifiiedby Dr Blacklock and Dr Moyes,- both blind themfelves, and both men of fuperior attainments; the former in elegant literature, and the latter in the phyfical faiences. We believe that the article Edu¬ cation was compofed by Mr Robert Heron, author of a hidory of Scotland now pu- blidiing, who likewife furnidied the greater part of what we have publifhed under the titles Religion and Society. The lives of Johnson and Mary $>ueen of Scots, with the articles Instinct, Love, Metaphysics, Miracle, the hidory of Ethics under Moral Philosophy, Oath, Passion, Plastic Nature, Polytheism, Prayer, Slavery, and Supper of the Lord, were contributed by Dr Gleig, Editor of the lad fix volumes; Grammar (c) and Theology by Dr Gleig and the Reverend James Bruce, A. B: late of Emanuel College, Cambridge; and Motion by Dr Gleig and Mr Tytler. The fydem of Medicine, which was publifhed. in the former edition, was revifed and improved for the prefent by Andrew Duncan, M. D. Fellow of the Royal Society of Edinburgh, and Profedbr of the Inditutes of Phyfic in the Univerfi¬ ty. The notes to the article Music were contributed by Dr Blacklock, and the hi¬ dory of the art by William Maxwell Morifon, Efq; advocate, who likewife favoured us with what we have publifhed on the fcience of Physiognomy. The articles My¬ steries, Mythology, and Philology, wTe owe to the erudition of David Doig, L. L. D. F. S. S. A. mader of the gram mar-fchool of Stirling, and author of two very ingenious Letters on the Savage State, addreded to the late Lord Karnes. Naviga¬ tion,- Parallax, Pendulum, Projection of the Sphere, Ship-Building, and. Naval Tactics, w7ere furnifhed by Andrew Mackay, L. L. D. F. R. S. E. of Aberdeen, and knowm to the Public as author of a treatife on the Theory and Frahlice of finding the Longitude (c) Mr Bruce, who communicated the moft valuable parts of the article Grammar, and who was for many years a ftudent in the univerfity of St Andrew’s, wiflies, from gratitude to his old matter, to declare, in this public manner, that, to the inftruftions of Dr Hunter, profefibr of humanity in that univerfity, he is indebted for much of what philological knowledge he may poffefs. We believe indeed that Dr Hunter may claim as his own the theory which we have given of the cafes of nouns, the do&rine concerning the inverfe acceptation of the adje&ive, and the refolution of the relative pronoun by means of the prepofition of inftead of the conjunftion and. There is nothing elfe in our article which the attentive reader may not find in the grammatical writings of Vojfms, Sca/iger, San&ius, Perizonius, Wallis, Rudd'man, Harris, Horne-Tooke, and Dr Gregory of Edinburgh. Difcoveries in grammar are not indeed to be looked for. They are nearly allied to thofe in metaphyfics; of which, it has been well obferved by one of the acuteft writers of the age, that the very appearance fhould be reje&ed as an error, if not as an impofition, upon mankind. XYl PREFACE. Longitude at Sea or Land. John Robifon, M. A. fecretary to the Royal Society of Edinburgh, and profeffor of natural philofophy in the Univerfity, did the Editor the honour of contributing to the Encyclopasdia Britannica the valuable articles Physics, Pneumatics, Precession of the Equinoxes, Projectiles, Pumps, Resistance of Fluids, River, Roof, Rovz-Making, Rotation, Seamanship, Signals, Sound, Spe¬ cific Gravity, Statics, Steam and StEngine, Strength of Materials, Tele¬ scope, Tide, Articulating Tkumvet, Variation of the Compafs, and IVater-WoKK.*. Philosophy is the joint production of Profeflbr Robifon and Dr Gleig. Physiology was furnifhed by John Barclay, M. D. of Edinburgh, whofe merits, if the Editor be not partial to his friend, it will raife high in the eftimation of men of fcience. The eflays on Predestination and Providence were contributed by Robert Forfyth, Efq; advocate ; the account of the French Revolution by Mr Forfyth and Dr Gleig ; and Oxygen and Phlogiston by John Rotheram, M. D. profeflbr of natural philofophy in the Univerfity of St Andrew’s. The other contributors to the firfl: part of the Work wre cannot enumerate ; but we know that much ufeful information was occafionally communicated by Dr Latham of Dartford in Kent, the celebrated ornithologift; by Dr William Wright phyfician- general to the forces in the Weft Indies under the command of Sir Ralph Abercrom¬ bie ; by the Reverend J. Hawkins, vicar of Halfted in Eflex ; by the late Mr Adams, mathematical inftrument-maker to his Majefty ; and by Mr William Jones, optician in Holborn, London. There is, however, no man to whom the Proprietors of the En¬ cyclopaedia Britannica feel themfelves under greater obligations than to Dr Black, for the very handfome offer which he made to the perfon who was at firft entrufted with the chemical department of the Work. And while they exprefs thus publicly their gratitude to him, may not the Editor declare how much he is indebted to his two afliftants, the Reverend James Walker, M. A. of St John’s College, Cambridge, and Mr James Thomfon of Crieff, preacher in the church of Scotland ? Of thefe gen¬ tlemen, who fucceflively had the care of the Work when he was neceflarily abfent, he could always fay, ^uihus in rebus ipji interejfe non pojfunius, in bis, opera nojlra vie aria fides amicarum Jupponitur. ENCYCLOPAEDIA Encyclopedia Britannica. A THE firft letter of the alphabet, in all the known » languages of the world, that of Ethiopia ex- cepted, in which it is the x 3th. It has defervedly the firft place in the alphabet, on account of its fimplicity, very little more being neceflary to its pronunciation than opening the mouth. In the Englifn language A Is the mark of three dif¬ ferent founds, termed, by our grammarians, the broad, the open, and the /lender A.. The firft refembles that of the German A, is found in feveral monofyllables, as •wall, fait, 8cc. and is pronounced as art in caufe. It is probable that the Saxons exprefled only this broad found of the letter, as it is ftill commonly retained in the northern diftricts of England, and univerfally throughout Scotland ; as, tauk for talk, ^ : e. g. Mel. Sacchar. & Mann, a, i vel aa, ^j. i. e. Take of honey, fugar, and manna, of each one ounce. A, put to bills of exchange, is in England an abbre¬ viation for accepted, and in France for accepte. It is likewife ufual among merchants to mark their fets of bool^s with the letters A, B, C, &c. inftead of the num¬ bers i, 2, 3, &c. A. A. A. The chemical abbreviation for Amalgama, or Amalgamation. AA, the name of feveral rivers in Germany and Swif- fcfland.

Long. 9. o. Lat. 47. 55. AAHUS, a little town in Germany, in the circle of Weftphalia, and bifhopric of Munfter. It is the capital of Aahus, a fmall diftritt; has a good caftle ; and lies north-eaft of Coesfeldt. E. Long. 7. x. Lat. 52. 10. AAM, or Ha am, a liquid meafure in common ufe among the Dutch, and containing 128 meafures called mingles, each weighing nearly 36 ounces avoirdupoife ; whence the slam contains 288 Englifh, and iqS-f- pints Paris meafure. AAR, the name of two rivers, one in Swifferland, and another in Weftphalia in Germany. It is alfo the name of a fmall ifland in the Baltic. AARASSUS (anc. geog.), a town of Pifidia, in the Hither Alia, thought to be the Anaffus of Pto¬ lemy. AARON, high-prieft of the Jews, and brother to Mofes, was by the father’s fide great grandfon, and by the mother’s grandfon, of Levi. By God’s command he met Mofes at the foot of mount Horeb, and they went together into Egypt to deliver the children of If- rael: he had a great fhare in all that Mofes did for their deliverance; the fcriptures call him the prophet of Mofes, and he acted in that capacity after the Ifraelites had paffed over the Red Sea. He afcended mount Si¬ nai with two of his fons, Nadab and Abihu, and fe- venty elders of the peoplebut neither he nor they went higher than half way, from whence they faw the glory, of God ; only Mofes and Jofhua went to the top, where they ftaid forty days. During their'abfence, Aaron, ov.etcome by the people’s eager intreaties, fet up the golden calf, which the Ifraelites worfhipped by his confent. This calf has given rife to various con- jectures. Some rabbies maintain that he did not make the golden calf; but only threw the gold into the lire,, to get rid of the importunities of the people ; and that certain magicians’, who mingled with the Ifraelites at their departure from Egypt, call this gold into the figur.e of a calf. According to fome authors, the fear of falling a facrifice to the refentment of the people by giving a refufal, made Aaron comply with their defire and they allege alfo, that he hoped to elude their requeft, by demanding of the women to contribute their ear-rings, imagining they would rather choofe to remain without a vilible deity, than be de¬ prived of their perfonal ornaments. This affair of the golden calf happened in the third month after the If¬ raelites came out of Egypt. In the firft month of the following year, Aaron was appointed by God high- Aaron,, prieft ; which office he executed during the time that, Aarfens- the children of Ifrael continued in the wildernefs. He v died in the fortieth year after their departure from Egypt, upon mount Hor, being then 123 years old; A. M. 2522, of the Julian period 3262, before the Chri- ftian sera 1452. With regard to the attempts of the Egyptian magicians to imitate the miracles performed by his rod, fee fome remarks under the article Ma¬ gician. Aaron and Julius (Saints), fuffered martyrdom together, during the perfecution under the emperor Dioclefian, in the year 303, about the fame time with Saint Alban the protomartyr of Britain. We are no¬ where told what their Britiffi names were, it being ufual with the Chriftian Britons, at the time»of baptifm, 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 fuffered the moft cruel torments. They had each a church ere&ed to his memory ; and their feftival is placed, in the Roman martyrology, on the firft of July. Aaron, or Harm, Al Rafchid, a celebrated khalif,. or Mahometan fovereign of the Saracen empire; whofe hiftory is given under the article Bagdad. Aaron Harifchon, a learned rabbi and caraite in the 15th century, wrote an Hebrew grammar, print¬ ed at Conftantinople in 1581; probably the fame with Aaron the caraite, who wrote a commentary on the five books of Mofes, which is in MS. in the French: king’s library. AARSENS (Francis), Lord of Someldyck and Spyck, was one of the greateft minifters for negocia- tion the United Provinces could ever boaft of. His father, Cornelius Aarfens, was Regifter to the States; and being acquainted with Mr Pleffis Mornay, at the Court of William Prince of Orange,, he prevailed upon him to take his fon under him, with whom he continued fome years. John Olden Barnevelt, who prefided over the affairs of Holland and all the United- Provinces, fent him aftemards agent into France,, where he learned to negociate under thofe profound politicians Hemy IV. Villeroy, Silleri, Roffie, Jaon- nin, &c. and he acquitted himfelf in fuch a manner as to obtain their approbation. Soon after, he was in- vefted with the chara&er of ambaffador, being the firft who was recognifed as fuch by the French court; at which time Henry IV. declared, that he ftiould take precedence next to the Venetian minifter. He refided in France 15 years; during which time he received; great marks of efteem from the king, who created him. a knight and baron ; and for this reafon he was re¬ ceived amongft the nobles of the province of Holland. However, he became at length fo odious to the French: court, that they defired to have him recalled. He was afterwards deputed to Venice, and to feveral Ger¬ man and Italian princes, upon occafion of the troubles in Bohemia. He was the firft of three extraordinary ambaffadors fent to England in 1620, and the fecond in 1641; in which'latter embaffy he was accompanied by the Lord of Brederode as firft ambaffador, and Heemfvliet as third, to treat about the marriage of Prince William, fon to the Prince of Orange. He was likewife ambaffador-extraordinary at the French court in- 1624, and the Cardinal de Richiieu having juft A B A L Aarfen* jufl taken the adminiftration of affairs into his hands, I! and knowing he was an able man, made ufe of him to A"ia' , ferve his own purpofes. He died in a very advanced age ; and his fon, who furvived him, was reputed the wealthieft man in Holland. Aarsevs (Peter), a painter, called in Italy Pietro X.,ongo, becaufe of his llature, was born at Amfterdam 1519. He was eminent for all kinds of fubje&sbut was particularly famous for altar-pieces, and for repre- fenting a kitchen with its furniture: he had the pain to fee a fine altar-piece of his deftroyed by the rabble in the infurre£lion 1566, though a lady of Alcmaer offered zoo crowns for its redemption. AAFvTGEN, or Aertgen, a painter of merit, was the fon of an woolcomber, and born at Leyden in • 1498. He worked at his father’s trade until he had attained the age of eighteen ; and then, having difco- vered a genius for deigning, he was placed with Cor¬ nelius Engelheihtz, under whom he made a confider- able progrefs in painting. He became fo diftinguilh- ed, that the celebrated Erancis Floris went to Ley¬ den out of mere curiofity to fee him. He found him inhabiting a poor half ruined hut, and in a very mean ftyle of living: He folicited him to go to' Antwerp, promifing him wealth and rank fuitable to his merit; but Aartgen refufed, declaring that he found more fweets in his poverty than others did in their riches. It was a cuftom with this painter never to work on Mondays, but to devote that day, with his difciples, to the bottle. He ufed to ftroll about the ffreets in the night, playing on the German flute, anddn one of thefe frolics was drowned in 1564. AASAR (anc. geog.), a town of Paleftine, in the tribe of Judah, fituate between Azotus and Afcalon. In Jerome’s time it was an hamlet. AB, the eleventh month of the civil year of the He¬ brews, and the fifth of their ecclefiaitical year, which begins with the month Nifan. It anfwers to the moon of July; that is, to part of our month of the fame name, and to the beginning of Auguft : it confifts of thirty days. The Jews faff on the firft of this month, in memory of Aaron’s death ; and on the ninth, becaufe on that day both the temple of Solomort, and that ere&ed after the captivity, were burnt; the former by the Chaldeans, and the latter by the Romans. The fame day is alfo remarkable among that people for the publication of Adrian’s edift, wherein they were for¬ bid to continue in Judea, or even to look.back when at a diftance from Jerufalem, in order to lament the defo- lation of that city. The 18th of the fame month is alfo a faff among the Jews ; becaufe the lamp in the fanc- tuary was that night extinguiflied, in the time of Ahaz. Ab, in the Syriac calendar, is the name of the laft fummer-month. The firft day of this month they call¬ ed Sunm Miriam, the faff of the virgin, becaufe the eaftern Chriftians faffed from that day to the fifteenth, ■which was therefore called Fathr-Miriam, the ceffa- tion of the faff of the virgin. ABA (or rather Abau) Hanifah or Han fa h, fir- named Al-Nooma, was the fon of Thabet, and born at Coufah in the 80th year of the Hegira. This is the inqft celebrated doftor of the orthodox Muffulmans, and his fett holds the principal efteem among the four which they indifferently follow. Notwithftanding this, 3 ] A B A . he was not very well efteemed during his life, infomuch that the khaliff Almanfor caufed him to be imprifoned at Bagdad, for having refufed to fubferibe to the opi-. ' .' nion of abfolute predeftination, which the Muffulmans call Cadha. -*But afterwards Abou Jofeph, who was the fovereign judge or chancellor of the empire under the khaliff Hadi, brought his dodlrine into fuch credit, that it became a prevailing opinion, That to be a good Muffulman was to be a Hanifite. He died in the 150th year of the Hegira, in the prifon of Bagdad aforefaid : and it was not till 335 years after his death, that Melick Schah, a fultan of the Selgiucidan race, built for him a magnificent monument in the lame city, whereto he adjoined a college peculiarly appropriated to fuch as made a profeffion of this fett. This was in the 485th year of the hegira, and Anno Chrifti 1092. The moft eminent fucceffors of this dodtor were Ahmed Benali, A1 Giaffas, and A1 Razi who was the matter of Naffari; and there is a mofque particularly appropriated to them in the temple of Mecca. Aba, Abas, Abos, or Abus, (anc. geog.), the name of a mountain of Greater Armenia, fituated between the mountains Niphatos and Nibonis. Accor¬ ding to Strabo, the Euphrates and Araxes rofe from this mountain ; the former running eattward, and the latter weftward. Aba. See Ab.®. ABACtENA (anc. geog.), a town of Media, and another of Cana in the Hither Afia. ABACJENUM (anc. geog.), a town of Sicily, whofe ruins are fuppofed to be thofe lying near Trippi, a citadel on an high and fteep mountain not far from Meflina. The inhabitants were called Abaacnini. ABACATUAIA, in ichthyology, a barbarous name of the zeus vomer. See Zeus. ABACH, a market-town of Germany, in Lower Bavaria, feated on the Danube. It is remarkable for Roman antiquities, and for fprings of mineral waters which are faid to be good for various diftempers. E. Long. 11. 56. Lat. 48. 53. ABACINARE, or Abbacinare, in writers of the middle age, a fpecies of punifhment, confifting in the blinding of the criminal, by holding a hot bafon or bowl of metal before his eyes. ABACK (a fea-term), the fituation of the fails when their furfaces are flatted again!! the mafts by the force of the wind. The fails are faid to be taken aback when they are brought into this fituatton, either by a fudden _ change of the wind, or by an alteration in the {hip’s courfe.

A 2 : ABACGT, ABA [ 4 Abacot ABACOT, the name of an ancient cap of ftate Abacus vvorn b7 tbe °f England, the upper part where- , of was in the form of a double crown. ABACTORS, or Aeactores, a name given to thofe who drive away, or rather fteal, cattle by herds, or great numbers at once ; and are therefore very pro¬ perly diftinguifhed from fares, or thieves. ABACUS, among the ancients, was a kind of cup¬ board or buffet. Livy, defcribing the luxury into which the Romans degenerated after the conqueft of Afia, fays, They had their abaci, beds, &c. plated over with gold. Abacus, among the ancient mathematicians, figni- fied a table covered with dull, on which they drew their diagrams; the word in this fenfe being derived from the Phoenician abak, duft. Abacus, in archite£lure,fignifies the fuperior part or member of the capital of a column, and ferves as a kind of crowning to both. Vitruvius tells us the abacus was originally intended to reprefent a fquare tile laid over an urn, or rather over a bafket. See Architec¬ ture, n° 15.—The form of the abacus is not the fame in all orders : in the Tufcan, Doric, and Ionic, it is generally fquare; but in the Corinthian and Compofite, its four iides are arched inwards, and embellifhed in the middle with fome ornament, as a rofe or other flower. Scammozzi ufes abacus for a con¬ cave moulding on the capital of the Tufcan pedeftal; and Palladio calls the plinth above the echinus, or boul- tin, in the Tufcan and Doric orders, by the fame name. Abacus is alfo the name of an ancient inllrument for facilitating operations in arithmetic. It is varioufly contrived. That chiefly ufed in Europe is made by drawing any number of parallel lines at the diftance oif two diameters of one of the counters ufed in the calcu¬ lation. A counter placed on the loweft line, figni- lies 1 ; on the 2d, 10; on the 3d, 100; on the 4th, IOOO, &c. In the intermediate fpaces, the fame counters are eftimated at one half of the value of the line immediately fuperior, viz. between the ift and 2d, 5 ; between the 2d and 3d, 50; &c. See the figure on Plate I. where the fame number, 1788 for example, is reprefented under both divifions by different difpofitions of the counters. Abacus is alfo ufed by modern writers for a table of numbers ready caff: up, to expedite the operations of arithmetic. In this fenfe we have Abaci of addition, of multiplication, of divifion. Chinefe Abacvs. See Swanpan. Abacus Pythagoricus, the common multiplication- table, fo called from its being invented by Pythagoras. Abacus LogiJUcus is a redangled triangle, whofe fides, forming the right angle, contain the numbers from 1 to 60 ; and its area, the fafta of each two of the numbers perpendicularly oppoiite. This is alfo called ,a canon of fexagefwials. Abacus & Palmula, in the ancient mufic, denote the machinery, whereby the firings of Polyple&ra, or inftruments of many firings, were ftruck with a plec¬ trum made of quills. Abacus Harmonious, is ufed by Kircher for the - ftrudure and difpofition of the keys of a mufical in¬ urnment, whether to be touched with the hands or the feet. ] ABA Abacus Major, in metallurgic operations, the name Atracui of a trough ufed in the mines, wherein the ore is wafhed. II ABADDON, is the name which St John in the , ^ us‘ Revelations gives to the king of the locuft, the angel of the bottomlefs pit. The infpired writer fays, this word is Hebrew, and in Greek fignifies ’Aa-oxxuav, /. e. a dejiroyer. That angel-king is thought to be Satan or the devil: but Mr le Clerc thinks, with Dr Hammond, that by the locuft which came out of the abyfs, may be underftood the zealots and robbers, who miferably afflided the land of Judea, and laid it in a manner wafte, before Jerufalem was taken by the Romans ; and that Abaddon, the king of the locuft, may be John of Gif- chala, who having treacheroufly left that town a little before it was furrendered to Titus, came to Jerufalem, where he foon headed part of the zealots, who acknow¬ ledged* him as their king, whilft the reft would not fubmit to him. This fubdivifio^ of the zealot party brought a thoufand calamities on the Jews. ABADIR, a title which the Carthaginians gave to gods of the firft order. In the Roman mythology, it is the name of a ftone which Saturn fwallowed, by the contrivance of his wife Ops, believing it to be his new-born fon Jupiter : hence it ridiculoufly became the objed of religious worlhip. ABvE, or Aba, (anc. geog.) a town of Pho- cis in Greece, near Helicon; famous for an oracle of Apollo older than that at Delphi, and for a rich temple plundered and burnt by the Perfians. ABAFT, a fea-term, fignifying the hinder part of a Ihip, or all thofe parts both within and without which lie towards the ftern, in oppofition to afore ; which fee.—Abaft, is alfo ufed as a prepofition, and fi'gnifies farther aft, or nearer the fern ; as, the barricade ftand* abaft the main-maft, i. e. behind it, or nearer the ftern. ABAISSED, Abaijfe, in heraldry, an epithet ap¬ plied to the wings of eagles, &c. when the tip looks downwards to the point of the fhield, or when the wings are fhut, the natural way of bearing them being extended, ABAK A khan, the 18th emperor of the Mo¬ guls, a wife and clement prince. He reigned 17 years, and is by fome authors faid to have been a Chriftian. It may be admitted, indeed,, that he joined with the Chriftians in keeping the feaft of Eafter, in the city Hanadau, fome fhort time before his death. But this is no proof of his Chriftianity; it being common, in times of brotherly love, for Chriftians and Mahometans to join in keeping the fame feafts, when each would compliment the other with doing honour to his folem- nity.

ABA [ Abana ABANA, or AmANA (anc. geog.), a river of Phoenicia, which, rifing from Mount Hermon, wafh- j ed the fouth and weft Tides of Damafcus, and falls into the Phoenician fea to the north of Tripolis, called Chryforrheas by the Greeks. ABANGA. See Ady. ABANO, a town of the Paduano, in the republic of Venice, famous among the ancients for its hot baths. ABANTES, a people who came originally from Thrace, and fettled in Phoceca, a country of Greece, where they built a town which they called Aba, after the name of Abas their leader; and, if we may credit fome ancient authors, the Abantes went afterwards into the ifland Euboea, now called Negropont: others fay the Abantes of Euboea came from Athens. The Aban¬ tes were a very warlike people, doling with their ene¬ mies, and fighting hand to hand. ABANTIAS, orAjiANTis (anc. geog.), a. name of the ifland Euboea in the Egean fea, extending a- long the coaft of Greece, from the promontory Su- nium of Attica to Theffaly, and feparated from Boeo- tia by a narrow ftrait called Euripus. From its length the illand wras formerly called Maoris ; afterwards A- bantias, or Abantis, from the Abantes, a people ori¬ ginally of Thrace, called by Homer oxirStv KopoovUi, from wearing their hair long behind, having in a battle ex¬ perienced the inconvenience of wearing long hair be¬ fore.

ABARIS, the Hyperborean ; a celebrated fage of antiquity, whofe hiftory and travels have been the fub- ject of much learned difcuffion. Such a number of fa- * Jamblich.bulous ftories * were told of him, that Herodotus him- V,\^as'felffeemst0fcruPlctorelatethem* Hetellsusonly+» cap. 36.'1V’ that this Barbarian was faid to have travelled with an arrow, and to have taken no fuftenance: but this does not acquaint us with the marvellous properties which were attributed to that arrow; nor that it had been given him by the Hyperborean Apollo. With regard to the occafion of his leaving his native country, Har- 1 Under the pocrationj tells us, that the whole earth being infefted word ’Afa- with a deadly plague, Apollo, upon being confulted, ff'f* gave no other anfwer, than that the Athenians Ihould offer up prayers in behalf of all other nations : upon which, feveral countries deputed ambaffadors to Athens, s ] ABA among whom was Abaris the Hyperborean. In this Abariv. journey, he renewed the alliance between his country-' v men and the inhabitants of the ifland of Delos. It appears that he alfo went to Lacedaemon ; fince, ac¬ cording to fome writers ||, he there built a temple con- j| Paufanlas, fecrated to Proferpine the Salutary. It is afferted, that P-94- he was capable of foretelling earthquakes, driving away plagues, laying ftormsj, &c. He wrote feveral books,! Porphyry as Suidasf informs us, viz. Apollo’s arrival into the j? Vlta country of the Hyperboreans; The nuptials of the river | under the Hebrus; or the Generation of the GodsA word ’ACa- colleftion of oracles; &c. Himerius the fophift ap- fl~ ^rom t^e clergY 5 though frequently confounded with them, becaufe a degree above laymen. In thofe early days, the abbots were fubjedt to the bifhops and the ordinary paftors. Their monafteries being remote from cities, built in the fartheft folitudes, they had no fhare in ecclefiaftical affairs. They went on Sundays to the parifh-church with the reft of the people ; or, if they were too remote, a prieft was fent them to adminifter the facraments ; till at length they were allowed to have priefts of their own body. The abbot or archimandrite himfelf was ufually the prieft : but his fundtion extended no farther than to the fpiritual affiftance of his monaftery; and he remained ftill in obedience to the bifliop. There being among the ab¬ bots feveral perfons of learning, they made a vigorous oppofition to the rifing herefies of thofe times; which firft occafioned the bifhops to call them out of their de* farts, and fix them about the fuburbs of cities, and at length in the cities themfelves: from which air a their degeneracy is to be dated. The abbots, now, foon wore off their former plainnefs and fimplicity, and be¬ gan to be looked on as a fort of little prelates. They afpired at being independent of the bifhops,; and became foinfupportable, that fome fevere laws were made againft them at the council of Chalcedon; this notwithftand- 4ng, in time many of them carried the point’of inde¬ pendency, and got the appellation of lord, with other badges of 'the epifeopate, particularly the mitre. Hence arofe new fpecies of diitindtions between the abbots. Thofe were termed mitred abbots, who were privileged to wear the mitre, and exercife epifcopal au¬ thority within their refpeftive precinfts, being exemp¬ ted from the jurifditftion of the bifhop. Others were Voi>» I. 1 1 ] ABB called crojiered abbots, from their bearing the crofter Abbot, or paftoral ftaff. Others were ftyled oecumenical or uni- v verfal abbots, in imitation of the patriarch of Conftan- tinople: while others were termed cardinal abbots, from their fuperiority over all other abbots.—Among us, the mitred abbots were lords of parliament; and called abbots-fovereign, and abbots-general, to diftinguifh them from the other abbots. And as there were lords abbots, fo there were alfo lords priors, who had exempt jurifdiftion, and were likewife lords of Parliament. Some reckon 26 of thefe lords abbots and priors that fat in parliament. Sir Edward Coke fays, that there were 27 parliamentary abbots and two priors. In the parliament 20 Rich. II. there were but 25 abbots and two priors: but in the fummons to parliament anno 4 Ed. III. more are named. At prefent, in the Roman-catholic countries, the principal diftin&ions obferved between abbots are thofe of regular and commendatory. The former take the vow and wear the habit of their order ; whereas the latter are feculars, though they are obliged by their bulls to take orders when of proper age. Anciently the ceremony of creating an abbot confifted in clothing him with the habit called cuculus, or cowl; putting the paftoral ftaff into his hand, and the fhoes called pedales on his feet; but at prefent, it is only a Ample benediction, improperly called, by fome, con- fecration. Abbot is alfo a title given to others befide the fupe- riors of monafteries: thus biftiops, whofe fees were formerly abbeys, are called abbots; as are the fupe- riors of fome congregations of regular canons, parti¬ cularly that of St Genevieve at Paris : and among the Genoefe, the chief magiftrate of their republic former¬ ly bore the title of Abbot of the people. It was like¬ wife ufual, about the time of Charlemagne, for feveral lords to affume the title of count-abbots, abba comites ; and that for no other reafon, but becaufe the fuper- intendancy of certain abbeys-was committed to them. ABBOT (George), archbifhop of Canterbury, was born OCt. 29. 1562, at Guildford in Surrey. He went through his ftudies at Oxford, and in 1597 was chofen principal of Univerfity College. In 1599, he was inftalled dean of Winchefter: the year following, he was chofen vice-chancellor of the univerfity of Ox¬ ford, and a fecondtime in 1603. In 1604, that tranf- lation of the bible now in ufe was begun by the direc¬ tion of king James; and Dr Abbot was the fecond of eight divines of Oxford, to whom the care of tranfla- ting the whole New Teftament (excepting the epiftles) was committed. The year following, he was a third time vice-chancellor. In 1608, he went to Scotland with George Hume Earl of Dunbar, to afiift in efta- bliftiing an union betwixt the kirk of Scotland and the church of England; and in this affair he behaved* with * Heylin’s fo much addrefs and moderation, that it laid the founda- jj'urianr^ tion of all his future preferment. For king James ever * after paid great deference to his advice and counfel; and upon the death of Dr Overton biftiop of Litchfield and Coventry, he named Dr Abbot for his fucceffor, who was accordingly conftituted bifhop of thofe two united fees in December 1609. About a month afterwards he was tranflated to the fee of London, and on the fe¬ cond of November thereafter was raifed to the archie- pifcopal fee. B It ABB [ io ] ABB Abbot, It is not however improbable, that his extravagant adulation of his royal matter, in which he went as far as any other court-chaplain could do, contributed not a little to the acceleration of his preferment. In the preface to a pamphlet he publiflied, the following fpe- cimen of ridiculous flattery occurs: Speaking of the king, he fays, “ whofe life hath been fo immaculate and unfpotted, &c. that even malice itfelf, which leaves nothing unfearched, could never find true blemifli in it, nor caft probable afperfion on it.—Zealous as Da¬ vid; learned and wife, the Solomon of our age; reli¬ gious as Jofias; careful of fpreading Chrift’s faith as Conftantine the Great; juft as Mofes ; undefiled in all his ways as a Jehofaphat and Hezekias; full of clemen¬ cy as another Theodofius.”—If Mr Walpole had feen this pafiage, he certainly would not have faid, that “ honeft Abbot could not flatter.” His great zeal for the Proteftant religion made him a ftrenuous prompter of the match between the Elector Palatine and the Princefs Elizabeth ; which was accor¬ dingly concluded and folemnized the 14th of February 1612, the archbilhop performing the ceremony on a ftage eredfced in the royal chapel. In the following year happened the famous cafe of divorce betwixt the lady Francis Howard, daughter of the earl of Suffolk, and Robert earl of Effex : an affair which has been by many confidered as one of the greateft blemifhes of king James’s reign; but the part acted therein by the archbilhop added much to the reputation he had already acquired for incorruptible integrity. The matter was by the king referred to a court of delegates. The archbilhop faw plainly, that his Majefty was very de- firous the lady Ihould be divorced; but he was, in his own judgment, diredtly againft the divorce. He la¬ boured all he could to extricate himfelf from this diffi¬ culty, by having an end put to the caufe by fome o- ther way than by fentence : but it was to no purpofe ; for thofe who drove on this affair, had got too great power to be reftrained from bringing it to the conclu- iion the king defired. The archbilhop prepared a fpeech, which he intended to have fpoken againft the nullity of the marriage, in the court at Lambeth ; but he did not make ufe of it, becaufe the king ordered the opinions to be given in few words. He continued, however, inflexible in his opinion againft the divorce; and drew up his reafons, which the king thought fit to anfwer himfelf. It need fcarce be added, that fentence was given in the lady’s favour. In 1618, the king pub- lifhed a declaration, which he ordered to be read in all churches, permitting fports. and paftimes on the Lord’s day : this gave great uneafinefs to the archbilhop ; who, happening to be at Croydon when it came thither, had the courage to forbid its being read. Being now in a declining ftate of health, the archbilhop ufed in the fummer to go to Hamp- fliire for the fake of recreation; and being invit¬ ed by lord Zouch to hunt in his park at Bramzill, he met there with the greateft misfortune that ever be- fel him; for he accidentally killed the game-keeper by an arrow from a erofs-bow which he Ihot at one of the deer.. This accident threw him into a deep melan- choly ; and he ever afterwards kept a monthly fall on Oiurch-hTft5 Tuefda>r’ tlle day on which this fatal mifehance hap- cent. xviii. Pened» and he fettled an annuity of 20/. on the wi- j. 87, dow*. There were feveral perfons who took an ad¬ vantage of this misfortune, to leffen him in the king’s Abhot. favour ; but his Majefty faid, “ An angel might have ' mifearried in this fort.” His enemies alleging that he had incurred an irregularity, and was thereby inca¬ pacitated for performing the offices of a primate ; the king direfted a commiffion to ten perfons to inquire into this matter. The refult, however, was not fatisfaftory • to his Grace’s enemies ; it being declared, that, as the mur¬ der was involuntary, he had not forfeited his archie- pifcopal character. The archbifhop thenceforward fel- dom affifted at the council, being chiefly hindered by his infirmities; but in the king’s laft illnefs he was fent for, and attended with great conftancy till his Majefty expired on the 27th of March 1625. He performed the ceremony of the coronation of king Charles I. though very infirm and much troubled with the gout. He was never greatly in this king’s favour; and the duke of Buckingham being his declared enemy, watched an opportunity of making him feel the weight of his difpleafure. This he at laft accomplilhed, upon the archbilhop’s refufing to licenfe a fermon, preached by Dr Sibthorpe to juftify a loan which the king had demanded, and pregnant with principles which tended to overthrow the conftitution. The archbilhop was immediately after fufpended from all his fun&ions as primate; and they were exercifedby certainbilhops com- miflioned by the king, of whom Laud, the archbilhop’s enemy, and afterwards his fucceffor, was one: while the only caufe afligned for this procedure was, That the archbilhop could not at that time perfonally attend thofe fervices which were otherwife proper for his cognifance and dire&ion. He did not, however, re¬ main long in this fituation ; for a parliament being ab- folutely neceffary, his Grace was fent for, and reftored to his authority and jurifdiftion. But not proving friendly to certain rigorous meafures adopted by the prevailing church-party, headed by Laud, whofe power and intereft at court were now very confiderable, his prefence became unwelcome there ; fo that upon the birth of the Prince of Wales, afterwards Charles II. Laud had the honour to baptize him, as dean of the chapel. The archbilhop being worn out with cares and infirmities, died at Croydon, the 5th of Auguft 1633, aged 71 years; and was buried at Guilford, the place of his nativity, and where he had endowed an hofpital with lands to the amount of 30^/. per annum. A ftately monument was ere died over the grave, with the effigy of the archbilhop in his robes. He Ihewed himfelf, in moft circumftances of his life,. a man of great moderation to all parties; and was de- firous thatthe clergy Ihould attradf the efteem ofthelaity by the fan ft it y of their manners, rather than claim it as due to their funftion. His notions and principles, however, not fuiting the humour of fome writers, have drawn upon him many fevere refleftions ; particularly, which is to be regretted, from the earl of Clarendon. But Dr Wei wood has done morejuftice to his merit and abilities*. He wrote feveral trafts upon various * Mewnirs,- fubjefts; and, as already mentioned, tranllated part of^ V?00* the New Teftament, with the reft of the Oxford di- vines, 1611. It is proper to obferve here, that there was another writer of both his names, who flourilhed fomewhat later. This George Abbot wrote A faraphrafe on ABB t Abbot Joh, A vindication of tbs fabbatb, and A paraphrafe ,, li on the Pfalm. , ABBOT (Robert ), elder brother to the former, and born at Guildford in 1560, went through his lludies in Baliol college, Oxford. In 1582, he took his degree of mailer of arts, and foon became a celebrated preach-- er ; and to this talent he chiefly owed his preferment. Upon his firll fermon at Worceller, he was chofen lec¬ turer in that city, and foon after rector of All-faints in the fame place. John Stanhope, Efq; happening to hear him preach at Paul’s-crofs, was fo pleafed with him, that he immediately prefented him to the rich living of Bingham in Nottinghamfhire. In 1597, he took his degree of do&or in divinity : and, in the beginning of king James’s reign, was appointed chaplain in ordinary to his Majefty ; who had fuch an opinion of him as a writer, that he ordered the dodtor’s book De Antichrijio to be printed with his own commentary upon part of the Apocalypfe. In 1609, he was eledled mafter of Baliol college ; which trull he difcharged with the ut- mofl care and affiduity, by his frequent ledlures to the fcholars, by his continual prefence at public exercifes, and by promoting temperance in the fociety. In No¬ vember 1610, he was made prebendary of Normanton in the church of Southwell; and, in 1612, his Majelly appointed him regius profeffor of divinity at Oxford. The hfme of his ledlures became very great; and thofe which he gave upon the fupreme power of kings againll Bellarmine and Suarez, fo much pleafed his Majelty, that, when the fee of Salilbury became vacant, he na¬ med him to that bilhoprick, and he was confecrated by his own brother at Lambeth, December 3, 1615. When he came to Salifbury, he found the cathedral running to decay, through the negligence and covet- oufnefs of the clergy belonging to it: however, he found means to draw five hundred pounds from the prebenda¬ ries, which he applied to the reparation of this church. He then gave himfelf up to the duties of his fundlion with great diligence and afiiduity, viliting his whole diocefe in perfon, and preaching every Sunday whilll health would permit. But this was not long : for his fe- dentary life, and clofe application to lludy, brought upon him the gravel and llone ; of which he died on the 2d of March 1618, in the fifty-eighth year of his age ; having not filled the fee quite two years and three months, and being one of the five bifhops which Salif¬ bury had in fix years. He was buried oppofite to the * JPor'bLsbifhop’s feat in the cathedral. Dr Fuller*, fpeaking of of Engtaxdin the two brothers, fays, “ that George was the more Sumy. « plau{ible preacher, Robert the greatell fcholar; “ George the abler llatefmen, Robert the deeper di- “ vine; gravity did frown in George, and fmile in “ Robert.” He publifhed feveral pieces ; he alfo left behind him fundry manufcripts, which Dr Corbet made a prefent of to the Bodelian library.

ABBREVIATE of Adjudications, in Scots law* an abftracl or abridgment of a decreet of adjudication, which is recorded in a regifter kept for that purpofe. ABBREVIATION, or Abbreviature, a con- traclion of a word or paffage ; made by dropping fome of the letters, or by fubllituting certain marks or cha- racters in their place.—Lawyers, phyficians, See. ufe abundance of abbreviations, partly for the fake of ex-1 pedition, and partly for that of myftery; but of all people the Rabbins are the moil remarkable for this practice, fo that their writings are unintelligible with¬ out the Hebrew abbreviatures. The Jewifli authors and copyifts do not content themfelves with abbreviating words like the Greeks and Latins, by retrenching fome of the letters or fyllables; they frequently take away all but the initial letters. They even frequently take the initials of feveral fucceeding words, join them to¬ gether, and, adding vowels to them, make a fort of barbarous word, reprefentative of all thofe which they have thus abridged. Thus, Rabbi Mofes ben Maie- men, in their abbreviature is Rambam, 8cc. ABBREVIATOR, in a general fenfe, a perfon who abridges any large book into a narrower compafs. Abbreviators, a college of 72 perfons in the chan¬ cery of Rome, who draw up the pope’s brieves, and re¬ duce petitions, when granted by him, into proper form for being converted in bulls. ABBUTALS, fignify the buttings or boundings of land towards any point. Limits were anciently di- llinguifhed by artificial hillocks, which were called botsmines ; and hence butting. In a defeription of the fite of land, the fides on the breadth are more properly adjacentes, and thofe terminating the length are abbu- tantes; which, in old furveys, were fometimes exprefs- ed by capitare, to head, whence abbutals are now call¬ ed head-lands.

It is called abduction, becaufe, from the con- clufion, it draws us on to prove the propofition affumed. Thus, in the fyllogifm, “ All whom God abfolves are free from fin ; but God abfolves all who are in Chrifl.; therefore all who are in Chrift are free from fin,”—the major is evident; but the minor, or affumption, is not fo evident without fome other propofition to prove it, as, “ God received full fatisfaclion for fin by the fuffer- ings of Jefus Chrift.” Abduction, in furgery, a fpecies of fradture, where¬ in the broken parts of the bone recede from each other.

ABEL, fecond fon of Adam and Eve, was a Ihep- herd. He offered to God fome of the firftlings of his flock, at the fame time that his brother Cain offered the fruits of the earth.

Thefe are the only circumftances Mofes relates of him.; though, were we to bike notice of the feveral particulars to which curiofity has given birth on this occafion, they would run to a very great length. But this will not be expe&ed. It is remark¬ able, that the Greek churches, who celebrate the feafts of every other patriarch and prophet, have not done the fame honour to Abel. His name is not to be found in any catalogue of faints or martyrs till the 10th century ; nor even in the new Roman martyrolo- gy.

ABELARD (Peter), one of the moft famous doc¬ tors of the twelfth century, was born at Palais near Nantz, in Britany: he was well learned in divinity, philofophy, and the languages ; but was particularly di- ftinguilhed by his Ikill in logic, and his fondnefs for de¬ putations, which led him to travel into feveral pro¬ vinces in order to give public proof of his acutenefs in that fcience. After having baffled many antagonifts, he read lectures in divinity with great applaufe at Paris; where he boarded with a canon whofe name was Ful- bert, and who had a very beautiful niece named He- loife. The canon ardently wifhed to fee this young lady make a figure among the learned, and Abelard was made her preceptor: but inftead of inftrufting her in ttie fciences, he taught her to love. Abelard now. performed his public funftions. very coldly, and wrote nothing but amorous verfes. Heloife proving with child, Abelard fent her to a fifter of his in Britany, where fire was delivered of a fon. To foften the canon’s anger, he offered to marry Heloife privately ; and the old man was better pleafed withthepropofalthan the niece; who,from a lingular excefs of paffion, chofe to be Abelard’s miftrefs rather than his wife; She married, however; but ufed of¬ ten to proteft upon oath that ftie was fingle, which provo¬ ked the canon to ufe her ill. Upon this, Abelard fent her to the monaftery of Argenteuil; where Ihe put on a religious habit, but did not take the veil. Heloife’s re¬ lations confidering this as a fecond treachery, hired ruf¬ fians, who, forcing into his chamber in the dead of the night, emafculated him. This infamous treatment made him fly to the gloom of a cloifter. He affumed the mo- naftic habit in the abbey of St Dennis; but the dif- orders of that houfe foon drove him from thence. He was. afterwards charged with-herefy; but after feveral perfecutions for his religious fentiments, he fettled in a folitude in the diocefe of Troies, where he built an ora¬ tory, to which he gave the name of the Paraclet. He was afterwards chofen fuperior of the abbey of Ruis in the diocefe of Vannes : when the nuns being expelled from the nunnery in which Heloife had been placed, he gave her his oratory ; where ftie fettled with fome of her fifter nuns, and became their priorefs. Abelard mixed the pRilofophy of Ariftotle with his divinity, and in 1140 was condemned by the council of. Rheims and Sens. Pope Innocent II. ordered him to be imprifoned, his books to be burnt, and forbid him ever teaching again. However, he. was foon after pardoned, at the felicitation of Peter the Venerable, who received him into his abbey of Clugni, where he led an exem¬ plary life. He died in the priory of Marcellus at Cha- . Ions, April 21, 1142, aged fixty-three. His corpfe was fent to Heloife, who buried it in the Paraclet. He left feveral works: the moft celebrated of which arc Abd-tree Abenfpefg.

Indeed it was not calculated for being of any long continuance. Thofe of this fe£t regulated marriage after the example of Abel; who, they pretended,. was manned, 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 fe&, when a man and woman entered into this fociety, they adopted a boy and a girl, who were to inherit their goods, and to marry upon the fame terms of not be¬ getting children, but of adopting two of different fexes.

It is a fmall but flourilhing place, well built, and Hill increafing. The town has been in an improving Hate for the forty laft years, and the number of inhabitants greatly augmented; wdiich is owing to the introduClion of manufactures. The number* at this time, is faid to be about four thou- fand: thefe principally confift of weavers of coarfe brown linens, and fome fail-cloth ; others are employ¬ ed in making white and coloured threads : the remain¬ der are either engaged in the (hipping of the place, or in the neceffary and common mechanic trades. The brown linens, or Ofnaburghs, were manufactured here before any encouragement was given by Government, or the linen company ereCted at Edinburgh. It ap¬ pears from the books of the ftamp-office in this town, that feven or eight hundred thoufand yards are annu¬ ally made in the place, and a fmall diftriCt round. Be- fides this export and that of thread, much barley and fome wheat is fent abroad. The foreign imports are flax, flax-feed, and timber, from the Baltic.

This port is of great antiquity : there is an agreement yet extant between the abbot and the burghers of Aberbrothic, inn 94, concerning the making of the harbour. - Both parties were bound to contribute their proportions ; but the largeft fell to the (hare 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, whofe very ruins give fome idea of its former magnificence. It was founded by Wil¬ liam the Lion in 1178, and dedicated to our celebra¬ ted primate Thomas a Becket. The founder was bu¬ ried here; but there are • no remains of his tomb, or of any other, excepting that of a monk of the name of Alexander Nicol. The monks were of the Tyro- nenfian order; and were firft brought from Kelfo, whofe abbot declared thofe of this place, on the firft; inftitution, to be free from his jurifdiClion. The laft abbot was the famous Cardinal Beaton, at the fame time archbifliop of St Andrew’s, and, before his death, as great and abfolute here as Wolfey was in England. King John, the Englilh monarch, granted this mona- ftery mod uncommon privileges ; for, by charter under his great feal, he exempted it a teloniis et confuetudine in every part of England, except London.

ABOLLA, a warm kind of garment, lined or dou¬ bled, worn by the Greeks and Romans, chiefly out of the city, in following the camp.—Critics and antiqua¬ ries are greatly divided as to the form, ufe, kinds, &c. of this garment. Papias makes it a fpecies of the toga, or gown ; but Nonius, and the .generality, a fpecies of ■ the pallium, or cloak. The abolla feems rather to have Rood oppofed to the togay which was a garment of peace, as the abolla was of war ; at leaf! Varro and Martial place them in this oppofite light. There feem to have been different kinds of Abollas, fitted to differ¬ ent occafions. Even kings appear to have ufed the abolla : "Caligula was affronted at king Ptolemy for ap¬ pearing at the fhews in a purple abolla, and by the eclat thereof turning the eyes of the fpeftators from the em¬ peror upon himfelf.

The term is alfo applied in the facred writings to idolatry and idols, be¬ caufe the worlhip of idols is in itfelf an abominable thing, and at the fame time ceremonies obferved by idolaters were always attended with licentioufnefs and other odious and abominable aftions. The abomination of deflation, foretold by the prophet Daniel, is fuppo- fed to imply the flatue of Jupiter Olympius, which Abon, Antiochus Epiphanes caufed to be placed in the temple Aborigines., of Jerufalem. And the abomination of deflation, men- " v T‘ tioned by the Evangelifts, fignifies the enfigns of the - Romans, during the laft fiege of Jerufalem by Titus,, on whom the figures of their gods and emperors were embroidered, and placed upon the temple after it was taken. ABON, Abonj^ or Abonis (anc. geog.),, a town, and river of Albion. The town, according to Camden, is Abingdon ; and the river Abhon or Avon. But by' Antonine’s Itinerary, the diftance is nine miles from the Venta Silurum, or Caer-Went: others, therefore, take the town to be Porfhut, at the mouth of the river Avon, over againft Briflol. Abhon or Avon, in the Celtic language, denotes a river. ABORIGINES, (Dionyfius of Halicarnaffus, Livy, Virgil) ; originally a proper name, given to a certain people in Italy, who inhabited the ancient Latium, or country now called Campagna di Roma. In this fenfe the Aborigines are diftinguifhed from the Jani- genas, who, according to the falfe Berofus, inhabited the country before them ; from the Siculi, whom they expelled; from the Grecians, from whom they defeended; from the Latins, whofe name they af- fumed after their union with ./Eneas and the Trojans ; laflly, from the Aufonii, Volfci, Oenotrii, &c. neigh¬ bouring nations in other parts-of the country. Whence this people came by the appellation, is much difputed. St Jerom fays, they were fa called, as being, a^/yaiT origine, the primitive planters of the country after the flood : Dion, of Halicarnaffus accounts for the name, as denoting them the founders of the race of inhabitants of that country: others think them fo called, as being originally Arcadians, who claimed to be earth-born, and not defeended from any people. Aurelius Viftor fuggefts another opinion, viz. that they were called Aborigines, q. d. Aherrigines, from ab “ from,” and er- rare “ to wander as having been before a wandering people. Paufanias rather thinks they were thus call¬ ed aro 0^.;, from “ mountains which opinion feems confirmed by Virgil, who, fpeaking of Saturn, the le- giflator of this people,-fays, Is genus indocile ac difperfum montibus altis Compofuit, legefque dedit. The Aborigines were either the original inhabitants of the country, fettled there by Janus, as fome imagine ; or by Saturn, or Cham, as others; not long after the difperfion, or even, as fome think, before it: Or they were a colony fent from fome other nation ; who ex¬ pelling the ancient inhabitants the Siculi, fettled in their place.—About this mother-nation there is great difpute. Some maintain it to be the Arcadians, parties of whom were brought into Italy at different times ; the firit under the conduft of Oenotrius, fon of Lycaon, 450 years before the Trojan war; a fecond from Theffaly ; a third under Evander, 60 years before the Trcjau war : befides another under Hercules ; and another of Lacedaemonians, who fled from the fevere difeipline of Lycurgus : all thefe uniting, are faid to have form¬ ed the nation or kingdom of the Aborigines. Otheis will have them of barbarian rather than Grecian origin, and to have come from Scythia; others from Gaul. Laftly, others will have them to be Canaanites, expell¬ ed by Jofhua. ABO [ 22 ] A B R Abortion The term Aborigines, though fo famous in antiquity, Aboakir 13 u^e<^ ,n modern geography only occafionally as an i „ appellative. It is given tathe primitive inhabitants of a country, in contradiltinCtion to colonies, or new races of people. ABORTION, in midwifery, the exclufion of a foe¬ tus before it has acquired a fufficient degree of perfec¬ tion to enable it to perform refpiration and the other vital functions.’ See Midwifery. The pra&iee of procuring abortions was prohibited by the ancient Greek legiflators Solon and Lycurgus. Whether or not it was permitted among the Romans, has been much difputed. It is certain the practice, which was by them called vifceribus vim inferre, was frequent enough : but whether there was any penalty on it, before the emperors Severus and Antonine, is the queftion. Noodt maintains the negative; and fur¬ ther, that thofe princes only made it criminal in one particular cafe, viz. of a married woman’s pra&ifing it out of refentmcnt againft her hufband, in order to defraud him of the comfort of children : this was or¬ dered to be punifhed by a temporary exile. The foun¬ dation on which the practice is faid to have been al¬ lowed, was, that the foetus, while in utero, was repu¬ ted as a part of the mother, ranked as one of her own vifcera, over which (he had the fame power-as over the reft : befxdes, that it was noj: reputed as a man, homo; nor to be alive, Otherwife than as a vegetable : confe- quently, that the crime amounted to little more than that of plucking unripe fruit from the tree. Seneca re- prefents it as a peculiar glory of Helvia, that Re had never, like other women, whofe chief ftudy is their beau¬ ty and fhape, deftroyed the foetus in her womb. The primitive fathers, Athenagoras, Tertullian,Minutius Fe¬ lix, Auguftin, &c. declaimed loudly againft the prac¬ tice as virtual murder. Several councils have con- i demned it. Yet we are told that the modern Romifti eccleiiaftical laws allow of difpenfations for it. Egane mentions the rates at which a difpenfation for it may be had. The practice of artificial abortion is chiefly in the hands of women and nurfes, rarely in that of phyfi- cians ; who, in fome countries, are not admitted to the profeflion without abjuring it. Hippocrates, in the oath he would have enjoined on all phyficians, includes their not giving the pejj'us abortivus; though elfewhere he gives the formal procefs whereby he himfelf procu¬ red in a young woman a mifcarriage. It may, how¬ ever, be obferved, that often all the powers of art prove ineffectual, and no lefs often do the attempts prove the means of puniftiment by the fatal confequences which they produce. Abortion, among gardeners, fignifies fuch fruits as are produced too early, and never arrive at maturity. ABORTIVE, is, in general, applied to whatever comes before its legitimate time, or to any defign which mifcarries. AsoRrirE Corn, a diftemper of corn mentioned by M. Gillet, and fufpeCted to be occafioned by infects. It appears long before harveft, and may be known by a deformity of the ftalk, the leaves, the car, and even the grain. Abortive Vellum is made of thefkinof an abortivecalf. ABOUKIR, a fmall town of Egypt, fituate in the defart between Alexandria and Rofetta. It is the an¬ cient Canopus, and is fituated, according to Mr Sava- About, ry, fix leagues from Pharos. Pliny fays, from the te- Graham ftimonies of antiquity, that it was formerly an ifland ; . ^ I and its local appearance makes this credible ; for the grounds around it are fo low, that the lea ftill covered a part of them in the days of Strabo. The town is built upon a rock, which forms a handfome road for fhipping, and was out of the reach of inundations. See Canopus. ABOUT, the fituation of a fhip immediately after ftie has tacked, or changed her courfe by going about and ftanding on the other tack.—About Jhip ! the or¬ der to the fhip’s crew to prepare for tacking. ABOUTIGE, a town in Upper Egypt, in Africa, near the Nile, where they make the beft opium in all the Levant. It was formerly a large, but now is a mean place. N. Lat. 26. 50. ABRA, a lilver coin ftruck in Poland, and worth about one (hilling Sterling. It is current in feveral parts of Germany, Conftantinople, Attracan, Smyrna, and Grand Cairo. ABRABANEL, Abarbanel, or Avravanel, (Ifaac), a celebrated rabbi, defcended from king David, and born at Lilbon A. D. 1437. He became coun- fellor to Alphonfo V. king of Portugal, and afterwards to Ferdinand the Catholic ; but in 1492 was obliged to leave Spain with the other Jews. In ihort, after re¬ fining at Naples, Corfou, and feveral other cities, he died at Venice in 1508, aged 71. Abrabanel paffed for one of the moft learned of the rabbis ; and the Jews gave him the names of the Sage,, the Prince, and the Great Politician. We have a Commentary of his on all the Old Tettament, which is pretty fcarce : he there principally adheres to the literal fenfe ; and his ftyle is clear, but a little diffufe. His other wwks are, A Trea- tife on the Creation of the World; in which he refutes Ariftotle, who imagined that the world was eternal: A Treatife on the explication of the prophecies relating to the Meffiah, againft the Chriftians: A book con¬ cerning articles of Faith ; and fome others lefs fought after. Though Abrabanel difcovers his implacable a- verfion to Chriftianity in all his writings, yet he treat¬ ed Chriftians with politenefs and good-manners in the common affairs of life. ABRACADABRA,a magical word,recommended by Serenus Samonicus as an antidote againft agues and feveral other difeafes. It was to be written upon a piece of paper as many times as the word contains letters, omitting the laft letter of the former every time, as in abracadabra the margin f , and repeated in the fame order; and then abracadabr fufpended about the neck by a linen thread. Abracada- abracadab bra was the name of a god worfhipped by the Syrians; abracada fo wearing his name was a fort of invocation of his aid: ^braca^ a pra&ice which, though not more ufeful, yet was lefs alnac irrational, than is the equally heathenilh practice among abra thofe who call themfelves Chriftians, of wearing various abr things, in expectation of their operating by a Sympa- thy, whofe parents were Ignorance and Superftition. ABRAHAM, the father and ftock whence the faithful fprung, was the fon of Terah. He was de¬ fcended 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 probable he was born in the city of Ur, in Chaldea, which he and his father left when they x went A B R [ 23 ] A B R Abraham, went to Canaan, where they remained till the death of lieves that part of it which makes Terah fo cruel ‘ Terah ; after which, Abraham refumed his firft defij of going to Paleltine. The Scriptures mention the fe- veral places he flopped 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 reflored as before; the victory he obtained over the four kings who had plundered Sodom ; his compliance with his wife, who inlifled that he fliould make ufe of their maid Hagar in order to raife up chil¬ dren ; the covenant God made with him, fealed with the ceremony of circumcifion; his obedience to the command of God, who ordered him to offer up his only fon as a facriflce, and how this bloody aft was prevented ; his marriage with Keturah ; his death at to Abraham be the informer againft his own fon.

W. Long. 1. 10. N. Lat. 48. 40. ABROGATION, the aft of abolifhing a law, by authority of the maker ; in which fenfe the word is fynonymous with abolition, repealing, and revocation. Abrogation ftands oppofed to rogation: it is diftin- guifhed from derogation, which implies the taking away only fome part of a law ; from fabrogation, which de¬ notes the adding a claufe to it; from abrogation, which implies the limiting or reftraining it; from difpenfation, which only fets it afide in a particular inftance ; and from antiquation, which is the refilling to pafs a law. ABROKANI, or Mallemolli, a kind of muflin, or clear white fine cotton cloth, brought from the Eaft Indies, particularly from Bengal; being in length 16 French ells and 3 quarters, and in breadth 5 eighths. ABROLKOS, the name of certain (helves, or banks of fand, about 20 leagues-from the coaft of Brazil. ABROTANUM, in botany. See Artemisia and Santolina. ABROTONUM (anc. geog.), a town and harbour on the Mediterranean, in the diftrift of SyrtisTarva, in Africa, one of the three cities that went to form Tripoly. ABRUS,inbotany, the trivial name of theGtYONE. ABRUZZO, a province in Naples. The river Pef- cara divides it into two parts; one of which is called Ulterior, whereof Aquila is the capital; and the other Citerior, whofe capital is Solomona. Befides the Ap- penines, there are two confiderable mountains, the one called Monte Cavallo, and the other Monte Maiello ; the top of which laft is always covered with fnow. A- bruzzo is a cold country ; but the rigour of the climate is not fo great as to prevent the country from produ¬ cing in abundance every thing requifite for the fupport of life. Vegetables, fruits, animals, and numberlefs other articles of fuftenance, not only furnilh ample provifion for the ufe of the natives, but alfo allow of exportation. There is fo' large a quantity of wheat, reaped, that many thoufands of quartets are annually (hipped off-. Much Turkey wheat is fent out, and the province of Teramo fells a gfeat deal of rice little in¬ ferior in goodnefs to that of Lombardy. Oil is a plen¬ tiful commodity, and wines are made for exportation ., on many parts of the coaft ; but wool has always been, D and A B R ■Abruzzo, an{l ftill Is, their ftaple commodity: the flocks, after paffing the whole fummer in the fine paftures of the mountains, are driven for the winter into the warm plains of Puglia, and a few fpots near their own coaft, where the fnow does not lie ; there are no manufactures of woollens in the province, except two fmall ones of coarfe cloth, and the greateft part of the wool is fent out unwrought. No filk is made here, though, mulberry-trees would grow well in the low grounds. Formerly the territory of Aquila furnilhed Italy al- moftexclufively withfaffron; but fince the culture of that plant has been fo much followed in Lombardy, it has fallen to nothing in Abruzzo. In the maritime tracks of country the cultivation of liquorice has been increafed of late years, but foreigners export the roots, in their natural ftate : in the province of Teramo there is a ma¬ nufactory of pottery-ware, for which there is a great demand in Germany, by the way of Triefte, as it is remarkably hard and fine ; but even this is going to decay, by being abandoned entirely to the ignorance of common workmen. It is not to be expeCted that any improvements will be made in arts and manufac¬ tures, where the encouragement and attention of fu- periors is wanting, and no pains taken to render the commodity more marketable, or to open better chan¬ nels of fale for it.. The only advantages thefe provin¬ ces enjoy, are the gift of benevolent nature ; but fhe has ftill greater prefents in ftore for them, and waits only for the helping hand of government to produce them. This whole coaft, one hundred miles in length, is utterly deftitute of fea-ports; and the only fpots where the produce can be embarked are dangerous in¬ convenient roads, at the mouths of rivers, and along a lee-fhore :: the difficulty of procuring {hipping, and'of loading the goods, frequently caufes great quantities of them to rot on hand ; which damps induftry, and prevents all improvements in agriculture. The hufband- man is a poor difpirited wretch, and wretchednefs pro¬ duces emigration: the uneven furfece of the country occafions it to be inhabited by retail, if the expreffion may be ufed, rather than in large mafies ; for there is not a city that contains ten thoufand people, and the moft of them would find it difficult to mufter three thoufand.. Villages, caftles, and feudatory eftates, are to be met with in abundance ; but the numbers of their inhabitants are to be reckoned by hundreds, not thoufands : in a word,, the political and focial fyftem of the province ftiows no figns of the vigour which na¬ ture fo remarkably difplays here in all her operations. The antiquary- and the naturalift may travel here with exquifite pleafure and profit; the former will find treafures of infcriptions, and inedited, monuments ap¬ pertaining, to the warlike nations that once covered the face of the country : the natural philofopher will have a noblq field for obfervation in the ftupendous monu¬ ments that rife on all fides. Monte-corno and Majella are among the moft interefting ; the firft is like an aged monument of nature, bald, and horribly broken on every afpeft : from various appearances, it is evident that its bowels contain many valuable veins of metallic ®re ; but the great difficulty of accefs renders the fearch of them almoft impra&icable. Majella has other me¬ rits, and of a gayer kind .-—nature has clothed its de¬ clivities and elevated fields with an infinite variety of iisr moft precious plants; vulnerary herbs grow there A B S in as great perfeftion as on the Alps of Swiflerland, Abnirze and are applied by the natives to wounds with equal fuccefs. _ _ thiatet. The chara&er of the inhabitants varies a little among v— themfelves, according to fituation and climate, but ef- fentially from the difpofition of the natives of the more fouthern provinces. This proceeds from a difference of origin : for the Lombards, who were barbarians,, but not cruel; poor, but hofpitable ; endowed with plain honeft ferife, though pofleffed of little acutenefs or fubtlety; remained peaceable proprietors of thefe mountainous regions, till the Normans, who were ac- cuftomed to a finiilar climate, came, and difpoflefled them. The Greeks*, who retained almoft every other part of the kingdom under their dominion, never had any fway here. For this reafon the Abruzzefi ftill bear a great refemblance to their northern progenitors or mafters : to this day, one may trace in them the fame goodnefs of heart, but great indolence, and re¬ pugnance to lively exertions ; a fault that proceeds ra¬ ther from a want of aftive virtue, than a difpofition to wickednefs. Hence it comes that in thefe provinces* where the proximity of the frontier almoft infures im¬ punity, fewer atrocious and inhuman deeds are heard of than in other parts of the realm. Remnants of ancient northern cuftoms exifted here fo late as the be¬ ginning of this century, and, among the mountaineers* very evident traces of the Frank and Teutonic lan¬ guages may be difcovered. ABSALOM, the fon of David by Maacah, was bro¬ ther to Thamar, David’s daughter, who was ravifhed by' Amnon their eldeft brother by another mother. Abfa- lom waited two years for an opportunity of revenging the injury done to his fifter ; and at laft procured the affaffination of Amnon atafeaft which he had prepared for the king’s fons. He took refuge with Talmai king of Geffiur; and was no fooner reftored to favour, but he engaged the Ifraelites to revolt from his father. Abfalom 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 thruft him through with three darts : David had exprefsly ordered his life to be fpared,. and extremely lamented him. ABSCESS, in forgery ; from ahfcedo, to depart. A cavity containing pus; or, a gathering of matter in a part: So called, becaufe the parts which were joined are now feparated ; one part recedes from another, to make way for the collected matter. See Surgery. ABSClSSE, in conics, a part of the diameter or. tranfverfe axis of a conic fedtion intercepted between the vertex or fome other fixed point and a femiordinate. See Conic Settioni. ABSCONSA, a dark lanthern ufed by the monks at the ceremony of burying their dead. ABSENCE, in Scots law: When a perfon cited before a court does not appear, and judgment is pro¬ nounced* that judgment is faid to be in abfence. No. perfon can be tried criminally in abfence. ABSINTHIATED, any thing tinged or impreg¬ nated with abfinthium or wormwood. Bartholin men¬ tions a woman whofe milk was become abfinthiated, and rendered as bitter as gall, by the too liberal ufe of wormwood. Vinum abfnthites, or poculum alfnthiatum, “ worm¬ wood wine,” is much fpoke of among the ancients as a whole- t 26 ] A B S [ 27 ] A B S AfelintViam wholefome drink, and even an antidote againit drunken- I) , nefs ; though feme have charged it with being offen- Abfolutlon. ^ve t0 tjie ancj liable to caufe fevers, caphalalgias, 7 ^ vomitings, uterine fluxes, &c. Ray alfo makes it a preventative of venery. According to the common opinion, it is made by infufing the leaves of the plant in wine ; but, according to Fehr, it ought to be pre¬ pared by fermentation, in order to correct the crudi¬ ties, and call forth a volatile fait; which laft, how¬ ever, does not exift in wormwood. Some prefer the dillilled water; but whatever virtues wormwood pof- felfes refide entirely in its effential oil. ABSINTHIUM, in botany, the trivial name of the common wormwood. See the article Artemi¬ sia. ABSIS, in aftronomy, the fame with apfis. See Apsis, ABSOLUTE, in a general fenfe, fomething that (lands free or independent. Absolute is more particularly underftood of a being or thing which does not proceed from any caufe, or does not fubfill by virtue of any other being, confi- dered as its caufe ; in which fenfe, God alone is abfo- lute. Abfolute, in this fenfe, is fynonymous with mdepen- dent, and Hands oppofed to dependent* Absolute alfo denotes a thing’s being free from conditions or limitations ; in which fenfe, the word is fynonymous with unconditional. We fay, an abfolute decree, abfolute promife, abfolute obedience. Absolute Govermnent, that wherein the prince is left folely to his own will, being not limited to the ob- fervance of any laws except thofe of his own.difcre- tion. Absolute Equation, in aftronomy, is the aggregate of the optic and eccentric equations. The apparent inequality of a planet’s motion arifing from its not be¬ ing equally diftant from the earth at all times, is call¬ ed its optic equation, and would fubfift even if the pla¬ net’s real motion were uniform. The eccentric ine¬ quality is caufed by the planet’s motion being uniform. To illuftrate which, conceive the fun to move, or to appear to move, in the circumference of a circle, in whofe centre the earth is placed. It is manifeft, that if the fun moves uniformly in this circle, it muft appear to move uniformly to a fpeclator on the earth, and in this cafe there will be no optic nor eccentric equation : but fuppofe the earth to be placed out of the centre of the circle, and then, though the fun’s motion fhculd be really uniform, it would not appear to be fo, being feen from the earth ; and in this cafe there would be an optic equation, without an eccentric one. Imagine farther, the fun’s orbit to be not circular, but elliptic, and the earth in its focus ; it will be as evident that the fun cannot appear to have an uniform motion, in fuch -ellipfe : fo that his motion will then be fubjedl to two equations, the optic and the eccentric. Absolute Number, in algebra, is any pure number Handing in any equation without the conjunction of li¬ teral charafters; as 2X+36 = 48 ; where 36 and 48 are abfolute numbers, but 2 is not, as being joined with the letter ,v. ABSOLUTION, in civil law, is afentence whereby the party accufed is declared innocent of the crime laid to his charge.—Among the Romans, the ordinary me¬ thod of pronouncing judgment was this: after the caufe had been pleaded on both Tides, the prseco ufed the Abfolution word dixerunt, q. d. they have faid what they had to , J] fay ; then three ballots were diftributed to each judge, tions^' marked as mentioned under the article A ; and as the ■ t—■> majority fell of either mark, the accufed was abfolved or condemned, &c. If he were abfolved, the pnetor difmifled him with videtur non fecifje, or jure videtur feciffe. _ ' Absolution, in the canon law, is a juridical a£l, whereby the prieft declares the fins of fuch as are pe¬ nitent remitted.—The Romanifts hold abfolution a part of the facrament of penance: the council of Trent, fell. xiv. cap. iii. and that of Florence, in the decree ad Armenos, declare the form or effence of the facrament to lie in the words of abfolution, I abfolve thee of thy fins. The formula of abfolution, in the Romifti church, is abfolute : in the Greek church, it is deprecatory ; and in the churches of the reformed, declarative. Absolution is chiefly ufed among Proteftants for a fentence whereby a perfon who Hands excommunicated is releafed or freed from that puniftiment. ABSORBENT, in general, any thing pofiefling the faculty of abforbing, or {wallowing up another. Absorbent Medicines, teftaceous powders, as chalk, crab-eyes, &c. which are taken inwardly for drying up or abforbing any acid or redundant humours in the fto- mach or inteftiues. They are likewife applied out¬ wardly to ulcers or fores with the fame intention. Absorbent Fejfels, a name given promifeuoufly to the la&eal veflels, lymphatics, and inhalent arteries. See Anatomy. Naturalifts fpeak of the like abforbents in plants, the fibrous or hairy roots of which are as a kind of vafa abforbentia, which attract and imbibe the nutritious juices from the earth. See Plants. ABSORBING, the fwallowing up, fucking up, or . imbibing, any thing : thus black bodies are faid to ab» forb the rays of light; luxuriant branches, to abforb or wafte the nutritious juices which ftiould feed the fruit of trees, &c. ABSORPTION, in the animal ceconomy, is the power whereby the abforbent vefiels imbibe the juices, &c. Absorftions of the Earth, a term ufed by Kircher and others for the finking in of large trails of land by means of fubterranean commotions, and many other accidents. Pliny tells us, that in his time the mountain Cym- botus, with the town of Eurites, which Hood on its fide, were wholly abforbed into the earth, fo that hot the leaft trace of either remained ; and he records the like fate of the city Tantalis in Magnefia, and after it of the mountain Sypelus, _both thus abforbed by a vio¬ lent opening of the earth. Galanis and Garnatus, towns once famous in Phoenicia, are recorded to have met the fame fate ; and the vaft promontory, cal¬ led Phlegium, in Ethiopia, after a violent earthquake in the night-time, was not to be feen in the morning, the whole having difappeared, and the earth clofed over it. Thefe and many other hiftories, attefted by the authors of greateft credit among the ancients, abun¬ dantly prove the fa61 in the earlier ages; and there have not been wanting too many inftances of more mo¬ dem date.

They are either one illand, or two, fepa- rated by a narrow channel, and joined by a bridge ; and are now called Chtrfe and Ofero. ABSTEMII, in church-hiftory, a name given to fhch perfons as could not partake of the cup of the eucharift on account of. their natural averfion to wine. Calvinifts allow thefe to communicate in the fpecies ot bread only, touching the cup with their lip ; which, on the other hand, is by the Lutherans deemed a pro¬ fanation. ABSTEMIOUS, is properly underftood of a per¬ ron who refrains abfolutely from all ufe of wine. The hiftory of Mr Wood, in the Medic. Tranf. vol. ii. p. 261. art. 18. is a very, remarkable exempli¬ fication of the very beneficial alterations which may be effected on the human body- by a ftrift courfe of abllemioufnefs. The Roman ladies, in the fir ft ages of the republic, were all enjoined to be abftemious ; and that it might appear, by their breath, whether or no they kept up to the injunction,, it was one of the laws of the Roman civility, that they fhould kifs their friends and relations whenever they accofted them. ABSTEMIUS (Laurentius) a native of Macerata* profefibr of belles lettres in Urbino, and librarian of duke Guido Ubaldo, under the pontificate of Alexan¬ der VI. He wrote, 1. Notes on moft difficult paflages of ancient authors. 2. Hecatomythium, i. e. A collec¬ tion of an too fables, &c. which have been often printed with, thofe of JEfop, Phsedrus, Gabrias, Avie- nus, &c. ABSTERGENT medicines, thofe employed for refolving obftruCtions,. concretions, &c. fach as foap, &c. ABSTINENCE, in a general fenfe, the a£t or ha¬ bit of refraining from fomething which we have a pro- penfion to or find pleafure in.—Among the Jews, va¬ rious kinds of abftinence were ordained by their law. Among the primitive Chriftians, fome denied them- felves the ufe of fuch meats as were prohibited by that law, others looked upon this abftinence with contempt; as to which, St Paul gives his opinion, Rom. xiv. 1—3. The council of Jerufalem, which was held by the Apo- ftles, enjoined the Chriftian converts to abftain from meats ftrangled, from blood, from fornication, and from idolatry. Abftinence, as prefcribed by the gof- pelj.is intended to mortify and reftrain the paffions, to bumble our vicious natures, and by that means raife our minds to a due fenfe of devotion. But there is another fort of abftinence, which may be called ritual, and confifts. in abftaining from particular meats at cer¬ tain times and feafons. It was the fpiritual monarchy of the weftern world which firft introduced this ritual abftinence ; the rules of which were called rogations ; but grofsly abufed from the true nature and defign of falling.—In England, abftinence from flelh has been enjoined by ftatute even fince the reformation, particu¬ larly on Fridays and Saturdays, on vigils, and on all commonly called The like injunctions were renewed under (^Elizabeth : but at the fame time it was declared, that this was done not out of motives of religion, as if there were any difference in meats ; but Afiftinenee. in favour of the confumption of filh, and to multiply the number of filhermen and mariners, as well as fpare the flock of Iheep. The great fail, fays St Auguftin, is to abftain from fin. Abstinence is more particularly ufed for a fpare diet, or a flendter parfimonious ufe of food, below the ordinary ftandard of nature. The phyficians relate wonders of the effefts of abftinence in the cure of many diforders, and pratrafting the term of life. The noble Venetian, Cornaro, after all- imaginable means had proved vain, fo that his life was defpaired of at 40, recovered, and lived to near 100, by mere dint of abftinence ; as he hirafelf gives the account. It is indeed furprifing to what a great age the primitive Chriftians of the eaft, who retired from the perfecu- tions into the deferts of Arabia and Egypt, lived, healthful and cheerful, on a very little food. Caffian affures U8„ that the common rate for 24 hours was 12 ounces of bread, and mere water: with this St An¬ thony lived 105 years; James'the Hermit 104; Ar- fenius, tutor of the Emperor Arcadius, 120 ; 3. Epi- , phanius, 115; Simeon the Stylite, M2 ; and Romania, T20. Indeed, we can match thefe inftances of longe¬ vity at home. Buchanan writes, that one Laurenc« preferved himfelf to 140 by force of temperance and labour; and, Spotfwood mentions one Kentigern, af¬ terwards called S. Mangali or Mungo, who lived to 185 by the fame means. Other inftances fee under the article Longevity.—Abflinence, however, is to be recommended only as it means a proper regimen;, for in general it muft have bad confequences when obferved without a due regard to conftitution, age; ftrength, £sV. According to Dr Cheyne, moft of the chronical difeafes, the infirmities of old age, and the fhort lives of Englifhmen, are owing to repletion ; and may be either cured, prevented, or remedied by abfli¬ nence : but then the kinds of abftinence which ought to obtain, either in ficknefs or health, are to be dedu¬ ced from the laws of. diet and regimen. Among the brute creation, we fee extraordinary in¬ ftances of long abftinence. The ferpent-kind, in parti¬ cular, bear abftinence to a wonderful degree. We have feen rattle-fnakes that had fubfifted many months with¬ out any food, yet ftill retained their vigour and fiercenefs. Dr Shaw fpeaks of a couple of ceraftes, (a fort of Egyp¬ tian ferpents), which had been kept five years in a bottle clofe corked, without any fort of food, unlefs ft fmitll quantity of fand wherein they coiled themfelves up in the bottom of the veffel may be reckoned as fuch : yet when he faw them, they had newly call their fkins, and were as brifk and lively as if juft taken. But it is even natural for divers, fpecies,to pafs four, five, or fix months.every year, without either eating or drink¬ ing. Accordingly, the tortoife, bear, dormoufe, fer- pent, &c. are obferved regularly to retire, at thofa feafons, to their refpedlive cells, and hide themfelves, fome in the caverns of rocks or ruins; others dig holes under ground; others get into woods, and lay them- felves. up in the clefts of trees.; others bury themfelves under water, GV. And thefe animals are found as fat and flelhy after fome months abftinence as before.— Sir G. Ent* weighed his tortoife feveral years fuccef-» fively, at its going to earth in October, and coming Tranf. out again in March; and found, that, of four pounds;»° 194- four A B S [ 29 ] A B S Abftinence four ounces, it only ufed to lofe about one ounce. AMradt —Indeed, we'have inftances of men paffing feveral . months as ftri&ly abftinent as other creatures. In par¬ ticular, the records of the Tower mention a Scotchman imprifoned for felony, and ftridlly watched in that for- trefs for fix weeks : in all which time he took not the kail fuftenance ; for which he had his pardon. Num- berlefs inftances of extraordinary abftinence, particu¬ larly from morbid caufes, are to be found in the different periodical Memoirs, Tranfaftions,. Ephemerides, &c.— It is to be added, that, in moll inftances of extraordinary human abftinence related by naturalifts, there were faxd to have been apparent marks of a texture of blood and humours, much like that of the animals abovementioned. Though it is no improbable opinion, that the air itfelf may furnilh fomething for nutrition. It is certain, there are fubftances of all kinds, animal, vegetable. See. floating in the atmofphere, which mull be continually taken in by refpiration. And that an animal body may be nourilhed thereby, is evident in the inftance of vi¬ pers } which if taken when firft brought forth, an cl kept from every thing but air, will yet grow very con- fiderably in a few days. So the eggs of lizards are ©bferved to increafe in bulk, after they are produced, though there be nothing to furnilh the increment but air algne ; in like manner as the eggs or fpawn of fifties grow and are nourifhed with the water. And hence, lay feme, it is that cooks, turnfpit-dogs, &c. though they eat but little, yet are ufually fat. See Fasting. ABSTINENTS, or Abstinentes, a fet of here¬ tics that appeared in France and Spain about the end of the third century. They are fuppofed to have bor¬ rowed part of their opinions from the Gnoftics and Manicheans, becaufe they oppofed marriage, condemn¬ ed the ufe of flelh meat, and placed the Holy Ghoft in the clafs of created beings. We have, however, no certain account of their peculiar tenets. , ABSTRACT, in a general fenfe, any thing fepa- rated from fomething elfe. Abstract Idea, in metaphyfics, is a partial idea of a complex objeft, limited to one or more of the compo¬ nent parts or properties, laying afide or abftra&ing from the reft. Thu?, in viewing an objeft with the eye, or recollecting it in the mind, we can eafily ab- ftraft from fame of its parts or properties, and attach ourfelves to others: we can attend to the fednefs.of a cherry, without regard to its figure, tafte, or confift- ence. See Abstraction. Abstract Tentis, words that are ufed to exprefs abftract ideas. Thus beauty, uglinefs, whitenefs, round- nefs, life, death, are ab ft raft terms. Abstract Numbers, are affemblages of units, con- fidered in themfelves without denoting any^particular and determined particulars. Thus 6 is an abftraft number, when not applied to any thing; but, if we fay 6 feet, 6 becomes a concrete number^ See the ar¬ ticle Number. Abstract Mathematics, otherwife called Pur? Ma¬ thematics, is that which treats of magnitude or quan¬ tity, abfolutely and generally confidered, without re- ftriftion to any fpecies of particular magnitude ; fuch are Arithmetic and Geometry. In this fenfe, abftraft mathematics is oppofed to mixed mathematics; wherein , Ample and abftraft properties, and the relations of quantities primitively confidered in pure mathematics; are applied to fenfible objefts, and by that means be¬ come intermixed with phyfical confiderations; fuch are Hydroftatics, Optics, Navigation, See. Abstract, in literature, a compendious view of any large work ; Ihorter and more fuperficial than an abridgment. ABSTRACTION, in general, the aft of abftraft- ing, or the ftate of being abftrafted. Abstraction, in metaphyfics, the operation of the mind when occupied by abftraft ideas. A large oak fixes our attention, and abftrafts us from the ftirubs that furround it. In the fame manner, a beautiful woman in a crowd, abftrafts our thoughts, and engrof- fes our attention folely to herfelf. Thefe are examples of real abftraftion : when thefe, or any others of a fi- milar kind, are recalled to the mind after the objefts; themfelves are removed from our fight, they form what is called abjiraft ideas, or the mind is faid to be em¬ ployed in abftraft ideas. But the power of abftraftion is not confined to objefts that are feparable in reality as well as mentally : the fize, the figure, the colour of a tree are infeparably connefted, and cannot exift in¬ dependent- of each other ; and yet we can mentally con¬ fine pur obfervations to any one of thefe properties, neglefting or abitrafting from the reft. Abftraftion is chiefly employed thefe three ways.. Firft, When the mind confiders any one part of a thing, in feme refpeft diffiinft from the whole; as a man’s arm, without the confideration of the reft of the body. Secondly, When we confider the mode of any fiibftance, omitting the fubftance itfelf; or when we feparately confider feveral modes which fubfift together in one fubjeft. This abftraftion the geometricians make ufe of when they confider the length of a body feparately, which they call a line, omitting the confi¬ deration of its breadth and thicknefs. Thirdly, It is by abftraftion that the mind forms general oruniverfal ideas; omitting the modes and relations of the parti¬ cular objefts whence they are formed. Thus, when we would underftand a thinking being in general, we gather from our felf-confcioufnefs what it is to think; and, omitting thofe things which have a particular re¬ lation to our own minds, or to the human mind, we • conceive a thinking being in general. Ideas formed in this manner, wliich.are what we pro¬ perly call abjlratt ideas, become general reprefentatives of all objefts of the fame kind; and their names ap¬ plicable to whatever exifts conformable to fuch ideas. Thus the idea of colour that we receive from chalk, fnow, milk, &c. is a reprefentative of all of that kind ; and has a name given it,■tfc-:hc.s« may be feen collefted and amplified in Cockburn>s^' ^r Inquiry into the Truth and Certainty of the Mo- tvhich encompaffed it round, and which our tranflators faic Deluge, p. 271, &c. After all, however, this render by deep. Thus it is that darknefs is faid to have been on the face of the abyfs. Abyss is alfo ufed for an immenfe cavern in the earth, wherein God is fuppofed to have colie ft ed all thofe waters on. the third day ; which, in our verfion, is rendered the fas, and elfewhere the great deep. Dr amazing theory of a central abyfs is far from be¬ ing demonftratedit will perhaps in feveral refpefls appear inconfiftent with found philofophy, as well as repugnant to the phenomena of nature. In particular, if we believe any thing like eleftive attraftion to have prevailed in the formation of the earth, we muft believe Woodward, in his Natural Hiftory of the Earth, af- that the feparation of the. chaos proceeded from the ferts, That there is a mighty colleftion of waters in- union of fimilar particles. It is certain that reft is fa- elofed in the bowels of the earth, conftituting a huge vourable to fuch operations of nature. As, therefore, Orb in the interior or central parts of it; and over the the central parts of the earth were more immediately furface of this water he fuppofes the terreftrial ftrata to quiefcent than thofe remote from the centre, it feems ab= be expanded. This, according to him, is what Mofes furd to fuppofe that the heavier and denfer bodies gave calls the great deep, and what moft authors render the place to the more light and fluid; that the central part great abyfs. The water of this vaft abyfs, he alleges, fhould cOnfift of water only, and the more fuperficial’ docs communicate with that of the ocean, by means of part of a cruft or (hell. Vid.

Abyss is more particularly ufed, in antiquity, to de¬ note the temple of Proferpine. It was thus called on account of the immenfe fund of gold and riches depo- fited there-; fome fay, hid under ground. Abyss is alfo ufed in heraldry to denote the centre of an efcutcheon.

ABYSSINIA, by fome called Higher Ethiopia, and by the Arabians Al Habajh, is bounded on the north by Nubia; on the call, by the Arabic gulph or Red Sea, and the kingdom of Adel; on the fouth, by the king¬ doms of Ajan, Alabo, and Gingiro; and on the weft, by the kingdom of Goram, and part of Gingiro; and is divided into a great number of provinces. The principal river is the Nile, which has its fource in this country; and the moft conliderable lake, that of Dam- bea, which difcharges itfelf into the Nile, is about 700 miles in length, and 90 in breadth. The air is pretty temperate in the mountains, and therefore their towns and ftrong holds are generally placed on them ; but in the valleys it is hot and fuffocating. The foil and face of the country is various. In fome places there are nothing but rocks and profound caverns; in others, efpecially where there are rivers, the land is exceedingly fruitful; and the banks of thefe ftreams are bordered with flowers of various kinds, many of which are un¬ known in Europe. The torrents in the rainy feafon walli a great deal of gold from the mountains. This feafon begins in May, when the fun is vertical, -or di- reftly over their heads, and ends in September.—The .country produces a great variety of animals, both tame and wild, fuch as lions, figers, rhinocerofes, leopards, ele¬ phants, monkeys, ftags, deer; horfes, camels, dromeda¬ ries, goats, cows, flieep; likewife oftriches, with a vaft variety of other birds. In the rivers are crocodiles and the hippopotamus. Travellers mention alfo a peculiar kind of bees, fmall, black, and without a fting, which hive in the earth, and make honey and wax that are extremely white. The country is greatly infefted with locufts, which devour every thing that is green where- ever they come. The inhabitants are Moors, Pagans, Jews, and Chri- ftians. The laft was the reigning and eftabliftied reli¬ gion when father Lobo vifited this country in 1624. This diverfity of people and religion is the reafon that the kingdom, in different parts, is under different forms of government, and that their laws and cuftoms are ex¬ tremely various. Some of the people neither fow their lands nor improve them; but live on milk and flefh, and encamp like the Arabs, without any fettled habita¬ tion. In fome places they pra&ife no rites of worlhip, though they believe that there dwells in the regions a- bove a Being who governs the world : This deity they call Oul. In thofe parts where Chriftianity is profeffed, it is fo corrupted with fuperftitious errors, and fo mingled with ceremonies borrowed from the Jews, that little befide the name of Chriftianity is to be found among them. (See the next article.)—They have two har- vefts in the year; one in winter, which begins in May, and lafts, with great rigour, through the months of A B Y July, Auguft, and September ; and the other in fpring. Every man who has a thoufand cows faves once a-year a day’s milk, and makes a bath for his friends ; fo that to give an idea of a man’s wealth, their common ex- preffion is, he bathes fo many times a-year. Their males marry about ten years old, and their females younger,. Their marriage tie is fo loofe, that they part whenever they find that they cannot live agreeably together. Befides the large towns, there are a great number of villages, which in fome places are fo' thick fown, that they look like one continued town : the houfes are very mean, being but one ftory high, and built of ftraw, earth, and lime. In moft of the towns the houfes are feparated by hedges, which are always green, and mixed with flowers and fruit-trees at a cer¬ tain diftance from each other, which affords an agree¬ able profpeft.—The government is monarchical. The, fovereign has the title of Negus, and is an abfolute prince. When he is in camp, the tents art fo regularly difpofed as to have the appearance of a city; and there is a captain over every divifion, to prevent diforders, and to execute juftice. The Abyffines in gaieral are of an olive complexion, tall, graceful, and well featured. Thofe who are nei¬ ther mechanics nor tradefmen (which few of them are) nor tillers of the ground, are inured to bear arms, which are a head-piece, a buckler, a coat of mail, bows and arrows, darts, pikes capped with iron at both ends, a fling, and a fword: they have very few fire-arms, and thofe were introduced by the Portuguefe. The habit of perfons of quality is a fine filken veil, or fine cotton, with a kind of fcarf. The citizens have the fame ha¬ bit, only coarfer. The common people have nothing but a pair of cotton drawers, and a fcarf which covers the reft of their body. The women are of a healthy conftitution, active, and moderately handfome, having neither flat nofes nor thick lips like the negroes; and nature is fo friendly, that they Hand in little need of midwives, which is indeed the cafe of moft countries in the torrid zone. They appear in public as in Europe, without being forbid the converfation of the men as among the Mahometans. Princeffes of the royal blood are not permitted to marry foreigners : and when they take the air, they go in great ftate, with 400 or 500 women attendants. Their language is the Ethiopxc, which bears a great affinity with the Arabic ; but par¬ ticular provinces have a different dialed!:. Manufactures are almoft wholly wanting in this coun¬ try; and the few trades which they have amongft them are always conveyed from the father to the children. They feem indeed by their churches, and other ruinated places, to have had a knowledge of architecture. But the workmen were fent for from other countries, and were forced to do all themfelves; fo that when thefe fa¬ brics were reared, efpecially the imperial palace built by Peter Pais, a Portuguefe architedl, the people flock¬ ed from all parts of Ethiopia to view it, and admired it as a new wonder of the world.—Gold, filver, copper, and iron, are the principal ores with which their mines abound in this extenfive part of Africa : but not above one third part is made ufe of by way of merchandize, or converted into money; of which they have little or no ufe in Abyffinia. They cut their gold indeed into fmall pieces for the pay of their troops,-and for expen- ces of the court, which.is but a modern cuftom among 2 them; 1 3> 1 Abyfliniai A B Y [ 3.3 1 A B Y jAHyffinia. them; the king’s gold, before the end of the 17th cen- tury, being laid up in his treafury in ingots, with in¬ tent to be never carried out, or never ufed in any thing but veflels and trinkets for the fervice of the palace. In the lieu of fmall money, they make ufe of rock fait as white as fnow and as hard as ftone. This is taken out of the mountain of Lafta, and put into the king’s warehoufcs ; where it is reduced into tablets of a foot long, and three inches broad, ten of which are worth about a French crown. When they are circulated in trade, they are reduced into Hill fmaller pieces, as oc- cafion requires. This fait is alfo applied to the fame purpofe as common fea-falt. With this mineral fait they purchafe pepper, fpices, and filk ftuffs, which are brought to them by the Indians, in their ports in the Red Sea. Cardamums, ginger, aloes, myrrh, caffia, civet, ebony-wood, ivory, wax, honey, cotton, and li¬ nens of variflus forts and colours, are merchandifes which may be had from Abyffinia; to which may be added fugar, hemp, flax, and excellent wines, if thefe people had the art of preparing them. It is affirmed there are in this country the findt emeralds that are any where to be found ; and, though they are found but in one place, they are there in great quantities, and fome fo large and fo perfedt as to be of almoft inefti- mable value. The greateft part of the merchan¬ difes above mentioned, are more for foreign than in¬ land trade. Their domeftic commerce confifts chiefly in fait, honey, buck-wheat, grey peafe, citrons, oran¬ ges, lemons, and other provifions, with fruits and her¬ bage neceflfary for the fupport of life. Thofe places that the Abyffian merchants frequent the moft, who dare venture to carry their commodities by fea them- felves, are Arabia Felix, and the Indies, particu¬ larly Goa, Cambaye, Bengal, and Sumatra. With regard to their ports on the Red Sea, to which fo¬ reign merchants commonly refort, the moft confider- able are thofe of Mette, Azum, Zajalla, Maga, Dazo, Patea, and Brava. The trade of the Abyffinians by land is inconfiderable. There are, however, bands of them who arrive yearly at Egypt, particularly at Cairo, laden with gold duft, which they bring to barter for the merchandifes of that country, or of Europe, for which they have occafion. Thefe cafilas or caravans, if we may be allowed thus to call a body of 40 or 50 poor wretches who unite together for their mutual af- iiftance in their journey, are commonly three or four months on their route, traverling forefts and moun¬ tains almoft impaflable, in order to exchange their gold for neceflaries for their families, and return immediately with the greateft part of the merchandife on their backs. Frequently the Jews or Egyptians give them large credit; which may feem furprifing, as they are beyond recourie if they Ihould fail of payment. But experience has ihown, that they have never abufed the confidence Tepofed in them ; and even in the event of death, their fellow-travellers take care of the effedts of the deceafed for the benefit of their families, but in the firft place for the difoharge of thofe debts contrafted at Cairo It remains only to be obferved, that one of the principal branches of trade of the Abyffines is that of flaves; who are greatly efteemed in the Indies and Arabia for the belt, and moft faithful, of all that the other kingdoms of Africa furnilh. The Indian and Arabian merchants frequently fubftitute them as their fadtors; and, on ac- Vot. I. count of their good fervices and integrity, not only of- Abyflinia, ten give them their liberty, but liberally reward them. —v*,“' . Into this part of the globe the admiffion of travel¬ lers has been fuppofed extremely difficult, and their re- _ turn from thence almoft impracticable. A Scotch gentleman, however, of family and fortune, James Bruce, Efq; of Kinnaird, is known not only to have entered that country, but to have refided in it fe- veral years, and returned fafe home, bringing with him many great curiofities. Soon after his return, the fol¬ lowing notice was given by the Count de Buffon in an advertifement prefixed to the 3d volume of his Hiftory of Birds: “ A new aid which I have received, and which I am anxious to announce to the public, is the free and generous communication which I had of the drawings and obfervations of James Bruce, Efq; of Kinnaird, wrho returning from Numidia, and the inte¬ rior parts of Abyffinia, ftopt in my houfe for feveral days, and made me a partaker of the knowledge which he had acquired in a tour no lefs fatiguing than ha¬ zardous. It filled me with the utmoft aftonifhment to view the numerous drawings which he had made and coloured himfelf. He pofTeffes the moft perfedl repre* fentations and defcriptions of the birds, fifties, plants, edifices, monuments, drefs, arms, &c. of different na¬ tions, all of them objedts worthy of knowledge. No¬ thing has efcaped his curiofity, and his talents have been proportioned to it. The Englifh government wall without doubt take proper meafures for the pub¬ lication of his work. That refpedtable nation, which has given a lead to all others in difcoveries of every kind, will not fail to add to its glory, by fpeedily com¬ municating to the w-orld at large, thofe of this excel¬ lent traveller, who, not contented with accurate de¬ fcriptions of nature, has made many important obfer¬ vations on the culture of different kinds of grains ; on the navigation of the Red Sea; on the courfe of the Nile, from its mouth to its fource, which he has been the firft to difcover; and on different particulars which may be of the higheft utility to commerce and agri¬ culture, thofe great arts which are but little known and ill cultivated. Yet, on thefe alone, the fuperiority of one nation over another does depend, and for ever will depend,” It is much to be regretted, that after fo long an in¬ terval, this gentleman’s difcoveries have not yet made their appearance. The delay has given rife to various fpeculations. Doubts have even been entertained con¬ cerning the credibility of the reports that have tran- fpired, or been gathered from his convei fation. His honour and abilities, however, are too extenlively known to be affefted by fuch injurious infrnuations. That he hath great talents for the information of his readers, appears by his differtation on the Theban harp*, which * gee Dr Burney hath inferted in the firft volume of his article Hiftory of Mufic, and in which are alfo mentioned Ha arm feveral of the Abyffinian inftruments. Mr Bruce,thls l)iC" moreover, is faid to have a great facility in learning tl0na‘ Y’ languages, and talents for drawing; nor perhaps was any other traveller furnifhed writh fo large and fcientific an apparatus of inftruments. Add to all this, that he is poffeffed of a fpirit and enterprife not eafily to be equalled. The fpeedy produftion, therefore, of fo in- terefting an account as he is capable of giving, of this almoft unfrequented part of Africa, cannot but ftill be E earneftly A B Y [ 34 1 A B Y .Abyffinia. earneftly wiilied for. In the mean time, the following l—v ' aut}jent{c anecdotes will not, it is prefumed, be unac¬ ceptable, nor appear foreign to the prefent article. Mr Bruce was appointed conful to Algiers, where he continued till 1=765.. In June 1764, he requefted leave of abfence from the fecretary of ftate for the fouthern department, in order to make fome drawings of antiquities near Tunis. In Mr Bruce’s laft letter from Algiers to the fame fecretary (dated December 29. 1764), he alludes to another leave of abfence, which he had likewife re¬ quefted, that he might vifit parts of the African con¬ tinent- He explains himfelf no further, in this letter ; but it is believed that he proceeded confiderably to the fouthward of Algiers, and made thofe very capital drawings of remains of Roman architefture, which many have feen fince his return to Britain. Before he fet out for Algiers, he informed fome of his friends, that the making fuch excurfions for thefe interefting purpofes was his- principal inducement for accepting the confulfhip.. How. long he continued in Africa, the prefent writer has not had: the opportunity of procuring information ; but having intentions afterwards of viiiting Palmyra, he was Shipwrecked on the coaft of Tunis, and plun¬ dered of every thing by the barbarous inhabitants. The moft diftrefling part of the lofs was probably that of his inftruments, fo neceffary to a fcientific tra¬ veller ; and though he afterwards procured fome of thefe, yet others (particularly, a quadrant) could not be recovered. Mr Bruce, however, determining to repair this lofs as foon as pofiible from France, fo much nearer to him than England, was fo fortunate as to be provided with a time-piece and quadrant from that quarter. Upon this occafion Lewis XV. prefented him with an iron quadrant of four feet radius, as he had probably reprefented to the academy of fciences his want of fuch an inftrument whilft he ftiould be in Abyflinia : Mr-Bruce brought back with him to Eng¬ land this cumbrous fellow-traveller, and, having put upon it an infcription to the following purport, is faid to have prefented it to the univerfity of Glafgow : With this inftrument given by the king of France, Lewis XV. Mr Bruce proceeded to the fources of the Nile, it being carried on foot, upon mens ftioulders, over the mountains of Abyflinia.” This information was received from that eminent maker of inftruments. Mr Nairne. Where and when Mr Bruce' received1 the French inftruments is not known ; but as he was ftill bent on vifiting Abyffinia, he gave a commiffion to Mr W. Ruffel, F. R. S. for a refle&ing telefcope, made by Bird or Short; a watch with a hand to point feconds, and the neweft and completeft Englifh aftronomical tables; all of which were to be fent to Mr Fremaux, and forwarded to him at Alexandria before Auguft. On the 29th of March 1768, Mr Bruce was at Sidon on the coaft of Syria, and wrote to Mr Ruffel from thence for the following additional inftruments, viz. a twelve-feet reflecting telefcope, to be divided into pieces of three feet, and joined with fcrews. This telefcope was alfo accompanied by two thermometers and two portable barometers. Mr Bruce moreover informed Mr Ruflel, that he was going into a country (viz. A- byffinia) from which few travellers had returned; and AbyKnii. wilhed Mr Ruflel, or his philofophical friends, would 11 ’ '* fend him their defiderata, as he was entirely at their fervice. Mr Bruce added, that if he could not obtain admiffion into Abyffinia, he ftill would do his bell in the caufe of fcience on the eaftern coaft of the Red Sea., As Mr Bruce had direfted the' inftruments to be ready for him at Alexandria by the beginning of Au¬ guft 1768, it is probable that he reached Cairo about that time ; from whence he proceeded to Abyffinia, by way of Jedda, Mazava, and Arquito. It is fuppofed that Mr Bruce did not continue long at Jedda, as he is faid to have explored the coaft on the eaft fide as low as Mocha, during which drawings were taken of many curious filh in the Red Sea. Mr Bruce muft alfo have entered Abyflinia, either at the latter end of 1768, or the very beginning of ilGg, as he made an oufervation in that part of Africa on the 15th of January of that year. In this perilous enterprife he was accompanied by a Greek fervant (named Michael), and an Italian paint¬ er, who probably affifted in the numerous articles w'hich might deferve reprefentation, and w'ho died of a flux before Mr Bruce’s return to Cairo in 1773. Bruce muft at times alft> have been affifted by many others, as his inftruments, apparatus for drawings, and other neceflaries, from their weight and bulk could not be eafily tranfported from place to place, and perhaps re¬ quired beafts of burden. To thefe likewife muft be added feveral medicines which enabled him to perform cures on the inhabitants, and’ probably occafioned the good reception he afterwards met with. Such, other particulars as happened to Mr Bruce, during his long refidence in this unfrequented country, muft be left to his own fuperior narrative ; and it ftiall fuffice, therefore, only to ftate, that he made a large number of obfervations to fix the fituations of places, out of w'hich 31 have been examined and computed by the aftronomer royal. The firft of thefe obferva¬ tions was made on the 10th of January 1769, and the laft on the 5th of Odlober 1772, from 30 to 38 de¬ grees of eaft longitude from Greenwich, and from, 12 to 28 degrees of north latitude. It need fcarcely be faid, therefore, that thefe obfervations, which in¬ clude fo large an extent of almoft unknown country, muft prove a moft valuable addition to geography ; and the more fo, becaufe the Portuguefe, who firft vifited Abyffinia, give neither longitude nor latitude of any place in that empire ; and Poncet only two latitudes,. viz. thofe of Sennar and Giefum. As Mr Bruce made the laft of his obfervations on the 5th of O(Sober 1772, it is probable that he might' then be on his return to. Cairo, through Nubia and Upper Egypt, where he arrived on the 15th of Ja¬ nuary 1773, after an abfence of more than four years ; bringing back with him his Greek fervant, named Michael. Mr Bruce continued at Cairo four months, during which time he had daily intercourfe with Mr Antes;, the fubftance of a letter from whom will contain the principal confutation of Baron Tott, and others, who. have been incredulous with regard to Mr Bruce’s ex— pefted narrative. Mr. A B Y [ 35 ] A B Y Abyfiinia. jyj;r Antes was bprn of German parents,' vvKo were ' poflefled of lands in the back fettlements of Penfylvania; Sand having fhowed early abilities as a mechanic, re¬ moved to Europe, where he diftinguifhed himfelf in the art of watch-making, which he learned without ap- prenticefhip. Being a member of the church known by the name of Unitas Fratrum, and commonly called Moravian, he vvifhed to be employed in their millions, and more flpecially that of the fame perfuafion efta- blilhed at Cairo, who always have delired to procure opportunities of inllrufting the Abyffinians. Mr Bruce had left Cairo fifteen months before Mr Antes came there ; and the intercourfe, therefore, be¬ tween them firft took place on Mr Bruce’s return in 1773- ... Having given this account of Mr Bruce and Mr Antes’s being firft known to each other, we Ihall ftate the fubftance of fome information received from the latter, who is now eftablilhed at Fulneck near Leeds, after having refided eleven years at Cairo. “ That Mr Bruce left Cairo in 1768, and proceeded thence by Way of Jeda, Mazava, and Arquico, into Abyffinia. “ That in 1771, a Greek came from Gondar (the capital) in Abyffinia, wffio had a draught from Mr Bruce on a French merchant at Cairo (named Roft) for fome hundreds of German crowns, which were paid immediately. This draught was accompanied by a letter from Mr Bruce, and was the firft time that he had been heard of at Cairo fince his departure in 1768. “ That after Mr Bruce’s return to Cairo in 1773, Mr Antes faw a young Armenian and his father (who came likewife from Gondar) at Mr Pini’s, an Italian merchant of Cairo, where they and Mr Bruce con- verfed in the Abyffinian language, and feemed glad to meet him again. “ That Mr Bruce returned to Cairo from Abyffinia by way of Nubia and Upper Egypt; which can be fully attefted by the Francifcan friars who are eftab¬ lilhed at Ifne near Afyuwan, which latter is the high- eft town of Upper Egypt. “ That during Mr Bruce’s ftay at Cairo, which was not lefs than four months, no day puffed without their feeing each other; which gave Mr Antes frequent op- ■portunities of inquiring with regard to Abyffinia, con¬ cerning which he was particularly interefted from a- reafon before ftated. “ That Mr Antes likewife frequently converfed with Michael, Mr Bruce’s Greek fervant; who is ftated to have by no means had a lively imagination, and who Abyflinfi. always agreed with the circumftances mentioned by his * mafter, and more particularly in relation to their having vifited the fources of the Nile ; which the Baron Tott doubts of, from having had a converfation with this fame Greek fervant. Mr Antes adds, “ That Baron Tott ftaid but a few days at Cairo; and, from his ffiort refidence in that country, hath-given feveral erroneous accounts relative to Egypt. Mr Antes, on the other hand, had almoft daily converfations with Michael for feveral years, and often in relation to the fources of the Nile.” Laftly, “ That after Mr Bruce left Cairo, Mr Antes had converfed with others who had known Mr Bruce in Abyffinia, and that he was there called Maalim Jd- kube, or Mr James.” After this ftate of fa&s, it is conceived that no one can entertain a reafonable doubt with regard to Mr Bruce’s not only having vifited, but refided long in Abyffinia ; though it is remarkable that the Jefuits ex- preffed the fame doubts in relation to Poncet, who had continued there nearly as long as Mr Bruce. Poncet happened to be a layman; and the Jefuits, perhaps, would not approve of any narrative that did not come from father Beneverit, who accompanied Poncet to Abyffinia, but unfortunately died there (a). Driven, however, from this hold, the obje&ors will poffibly retain their incredulity as to many particulars to be related. The firft of thefe is, the having vifited the fources of the Nile ; which, from claffical education, we can- n6t eafily believe, as they were unknown to the an¬ cients, though they had fo great curiofity with regard to this difeovery.” Many things, however, have been accomplifhed by travellers in modern times, which the ancients ne¬ ver could atchieve, and which may be attributed to their want of enterprife (as travellers at leaft), of lan¬ guages, and laftly the not being able to procure cre¬ dit when in a diftant country. Mr Bmce could not have continued fo long as he did in Abyffinia, unlefs he had drawn from Gondar upon a merchant eftabliffied at Cairo. The difficulty, however, with regard to reaching the fourcee of the Nile, arifes principally from the un¬ civilized ftate of Abyffinia, unlefs the traveller hath a proper introduftion (3). When once this is procured, all difficulties feem to ceafe, as we find by Lobo’s (c) account of this fame difeovery, and likewife by Pon- E 2 cet’s {a) It muft be admitted, however, that we owe to the zeal of the Jefuits the bed accounts we have both of China and Paraguay. Few laymen have been a.vho was prevented by illnefs from vi- ' ■v ' filing the very fpot, but hath given an ample relation from an Abyfiinian who had often been there. Pon- cet, moreover, had obtained leave from the emperor to make this journey, which he ftates as not being a di- ftant one, and that the emperor hath a palace near the very fources. If it be doubted whether Mr Bruce hath vifited every fource of the Nile, it may be anfwered, that perhaps no Englifhman hath taken this trouble with regard to the fources of the Thames, which, like moft other great rivers, is probably derived from many fprings and rills in different direflions. The other objection which we have often heard, is, “ That Mr Bruce hath mentioned in converfation, that the Abyffinians cut a flice from the living ox, efteeming it one of their greateft delicacies.” This fort of dainty, indeed, is not fo confidered in other parts of the globe ; but every nation almoft hath its peculiarities in the choice of their food. Do not we eat raw oyfters within a fecond of their being fepa- rated from the fhell ? And do not we roaft both them and lobfters whilft alive ; the barbarity of which prac¬ tice deems to equal that of the Abyffinians ? Do not cooks fkin eels whilft alive ? And do not epicures crimp fiffi for the gratification of their appetites ? That the Abyffinians eat beef in a raw ftate, is a- greed both by Lobo and Poncet; and the former fays, rseking from the beaft. Mr Antes, moreover, was told by a Francifcan monk, who went with the cara¬ van from Abyffinia to Cairo (r/- mum mobile and the. folar revolution ; which was com¬ puted at three minutes and 56 feconds. Accelf.ration of the Moon, a term ufed to exprefs the increafe of the moon’s mean motion from the fun, compared with the diurnal motion of the earth ; fo that it is now a little fwifter than it was formerly. Dr Hal¬ ley was the firft who made this difcovery; and he was- led to it by comparing the ancient eclipfes obferved at Babylon with thofe obferved by Albatennius in the ninth century, and fome of his own time. He was not able to afcertain the quantity of this acceleration, becaufe the longitudes of Bagdad, Alexandria, and Aleppo, where the obfervations were made, had not been AC C . . t 5 Accelera- been accurately determined. But iince his time, the ti" to its fubjeA. Accidental, in philofophy, is applied.to that ef- feA which flows from fome caufe intervening by acci¬ dent, without being fubjeA, or at leaft -without any appearance of being fubjeA, to general laws or regu¬ lar returns. In this fenfe, accidents oppofed to conjlant and principal. Thus-the .fun’s place is, with refpeA to the earth, 'the conftant and principal caiife of the heat in fummer, and the cold in winter; whereas winds, fnows, and rains, are the accidental caufes which of¬ ten alter and modify, the a&ion of the principal caufe. Accidental Point, in perfpeftive, is that point in tlie-horizontal line where the projections of two lines . parallel to each other meet the perfpe&ive plane. AceiDF.iiTAL Colours, are thofe which depend upon the dffe&ions of the eye, in contradiftinAion to thofe which belong to the light itfelf. The impreffions made upon the eye by looking ftedfaftly at a particular co¬ lour are various, according to the fingle colour or com¬ bination of colours in the objeA; and they continue for fome time after the eye is withdrawn, and give a falfe colouring to other objeAs. Mr Buffon has en¬ deavoured to trace the conneAions which thefe acci¬ dental colours have with fuch as are natural, in a va¬ riety of inftances. The fubjeA has alfo been confidered by De la Hire, and M. Epences ; and M. d’Arcy has contrived a machine for determining the duration of " v the effeAs of light, and after feveral trials, finds that , it continues about eight thirds of a minute. ACCIPENSER, in ichthyology, a genus of fifhes belonging to the Amphibia Nantes of Linnaeus. The accipenfer has a fingle linear noftril: the mouth is in the under part of the head, and contains no teeth ; the cirri are below the fnout, and before the mouth. There are three fpecies of this genus, viz. 1. The ruthenus has 4 cirri, and 15 fquamo.us pro¬ tuberances. It is a native of Ruffia. 2. The hufo has 4 cirri; the body is naked, i. s. has no prickles or protuberanoes. The dr in of the hufo is fo tough and ftrong, that it is employed for ropes in carts and other wheel-carriages; and the ichthyo- collo, or isinglass of the Ihops, famous as an agglu- tinant, and ufed alfo for the fining of wines, is made from its found or feales. The ancients were acquaint¬ ed with the fiih that afforded this drug. The hufo is the largeft of the genus, and grows to 24 feet in length. •It inhabits the Danube and the rivers of ,Rufiia. 3. The fturio, or ftufgeon, with 4 cirri and n fquamous protuberances on the back. This fifh an¬ nually afeends our rivers, but in no great numbers, and is taken by accident in the falmon-nets. It feems a fpi- ritlefs fifh, making no manner of refiftance when en¬ tangled, but is drawn out of the water like a lifelefs lump. It is feldom taken far out at fea, but frequents ■fuch parts as are not remote from the aeftuaries of great rivers. It is admired for the delicacy and firmnefs of its fiefh, which is white as veal, and extremely good when roafted. ft is generally pickled. The molt we receive comes either from the Baltic rivers or North America. Great numbers are taken during fummer in ■the lakes Frifchehaff, and Curifch-haff near Pillau, in large nets made of fmall cord. The adjacent fhores are /ormed into diftriAs, and .farmed out to companies of fifhermen, fome of which are rented for fix thoufand Acdpltcr guilders, or near three hundred pounds, per annum. Ac||;us> They are found in vaft abundance in the American ri-. ‘ vers in May, June, and July,; at which time they leap fome yards out of the water, and, falling.on their fides, make a noife to be heard in Hill weather at fome miles diftance.. Caviare is made of the roes of this, and alfo of all the other forts of fturgeons, dried, falted, and packed up clofe. Ichthyocolla, or ifinglafs, is likewife made of the found of this fiih, as well as that of the others; but in very fmall quantity. The Iturgeon * grows to a great fize, to the length of 18 feet, and to the weight of 500 pounds, but it is feldom taken in our rivers of that bulk. In the manner of breeding, this fifh is an exception among the cartilaginous kind,; being, like the bony fifh, oviparous, fpaWning in wa¬ ter. ACCIPITER, .the name of Linnoeus.’s firfl order of Birds. See Zoology. Among the Romans, the term accipiter fignified a hawk, and which, from its being very -carnivorous, they confidered as a bird of bad omen ; Odimus aedpitrem, quia Jemper vivit in armis. Ovid. Pliny, however, tells us, that in fome cafes, particu¬ larly in marriage, it was efteemed a bird of good omen, becaufe it never eats the hearts of other birds ; intimating thereby, that no differences in a married flate ought to reach the heart. The accipiter was worfhipped as a divinity by the inhabitants of Tentyra, an ifland in the Nile, being confidered by them as the image of the fun ; and hence we find, that luminary re- prefented, in hieroglyphics, under the figure of a hawk. ACCISMUS, denotes a feigned refufal of foptc- thing which a perfon earneftly defires. The word is Latin ; or rather Greek, A-oue-^of, fuppofed to be form¬ ed from Acco, the name of a foolifh old woman noted, in antiquity for an affeAation of this kind. Accifmus is fometimes confidered as a virtue ; fome- times as a vice, which Auguftus and Tiberius prac- tifed with great fuccefs. Cromwell’s refufal of the crown of England may be brought as an inflance of an Accifmus. Accismus is more particularly ufed, in rhetoric, as a fpecies of irony. ACCITUM, (anc. geog.), a town of Hifpania Ba- tica, now Finiana, as appears from an ancient inferip- tion; fituate on an eminence of the mountains Alpu- xaras in Granada. ACCIUS (Lucius), a Latin tragic poet, thefon of a freedman, and, according to St Jerom, born in the eonfulfhip of Hoftilius .Mancinus and Attilius Serra- nus, in the year of Rome 583 ; but there appears fomewhat of confufion and perplexity in this chronolo¬ gy. He made himfelf known before the death of Pa- cuvius, a dramatic piece of his being exhibited the fame year that Pacuvius brought one upon the ftage,, the latter being then eighty years of age, and Accius only thirty. We do not know the name of this piece of Accius’s, but the titles of feveral of his tragedies are mentioned by various authors. He wrote on the moft celebrated ftories which had been reprefented on the Athenian ftage; as Andromache, Andromeda, A- treus, CLytemneftra, Medea, Meleager, Philocletes, ACC [ 55 ] ACC Accius, the civil wars of Thebes, Tereus, the Troades, &c. Acclama- He d;d not aiways> however, take his fubjefts from l ' i the Grecian ftory ; for he compofed one dramatic piece wholly Roman : it was intitled Brutus, and related to the expulfion of the Tarquins. It is affirmed by fome, that he wrote alfo comedies ; which is not unlikely, if ' he was the author of two pieces, the Wedding and the Merchant, which have been afcribed to him. He did not confine himfelf to dramatic writing ; for he left other productions, particularly his annals, mentioned by Macrobius, Prifcian, Feilus, and Nonius Marcel- lus. He has been cenfured for writing in too harlh a ftyle, but in all other refpeCts has been elteemed a very great poet. He was fo much elteemed by the public, that a comedian was punilhed for only mentioning his name on the Itage. Cicero fpeaks with great derifion of one Accius who had written a hiftory ; and, as our author had wrote annals, fome infiii that he is the per- - fon cenfured : but as Cicero himfelf, Horace, Quinti¬ lian, Ovid, and Paterculus, have fpoken of our author with fo much applaufe, we cannot think it is him whom the Roman orator cenfures with fo much feverity. There was alfo in this age a pretty' good orator of the fame name, again!! whom Cicero defended Cluen- tius. He was born in Pifaurum, and perhaps was a re¬ lation of our poet. ACCIUS, a poet of the 16th century, to whom is attributed A Parapbrafe of JEfop's Fables, on which Julius Scaliger bellows great encomiums. ACCLAMATION, a confufed noife or Ihout of joy, by which the public exprefs their applaufe, elleem, or approbation. Acclamation, in a more proper fenfe,'denotes a certain form of words, uttered with extraordinary ve¬ hemence, and in a peculiar tone fomewhat refembling a fong, frequent in the ancient affemblies. Acclama¬ tions were ufually accompanied with applaufes, with which they are fometimes confounded: though they ought to be dillinguilhed; as acclamation -was given by the voice, applaufe by the hands ; add, that accla¬ mation was alfo bellowed on perfons abfent, applaufe only on thofe prefent. Acclamation was alfo given by women, whereas applaufe feems to have been confined to men. Acclamations are of various kinds; ecclefiailical, military, nuptial, fenatorial, fynodical, fcholallic, thea¬ trical, &c. We meet with loud acclamations, mulical, and rythmical acclamations ; acclamations of joy and refpeft, and even of reproach and contumely. The former, wherein words of happy omen were ufed, were alfo called, Laudationes, et bona vota, or good wilhes; . the latter, Execrationes et convicia. Suetonius furnilhes an inltance of this lalt kind in the Roman fenate, on occafion of the decree for'demolilhing the llatues of Domitian, when the fathers, as the hillorian reprefents it, could not refrain from contumelious acclamations of the deceafed. The like wrere Ihown after the death of Commodus, where the acclamations run in the follow¬ ing ftrain : Hofti pair lie honores detrahantur, parricide bonores detrahantur ; hojlis ftatuas undique, parricida fatuas undique, gladiatoris fiatuas undique, &c.—The formula, in acclamations, was repeated fometimes a greater, fometimes a lelfer, number of times. Hence we find in Roman writers, acclamatum ejl quinquies, et tides; five times, and twenty times; fometimes. aifo fdagics, and even oftuagies; fixty and eight times. Acclamations were not unknown on the theatres in Ac the earliell ages of the Roman commonwealth; but they were artlefs then, and little other than confufed fixouts. Afterwards they became a fort of regular con-, certs. That mentioned by Phaedrus, Lztare incolumis Roma falvo principe, which was made for Augullus, and proved the occafion of a pleafant millake of a flute- player called Princeps, Ihows that mufical acclamations wrere in ufe in that emperor’s reign. Revertentem cx Provinda moduiatis car minibus profequebantur, fays Suetonius, who gives another inllance in the time of Tiberius : a falfe report of Germanicus’s recovery be¬ ing fpread through Rome, the people ran in crowds to the capitol with torches and victims, finging, Salva Roma, Salva Patria, Salvus ejl Germanicus Nero, paffionately fond of mufic, took fpecial care to improve and perfeft the mufic of acclamations. Charmed with the harmony wherewith the Alexandrians, who came to the games celebrated at Naples, had fung his praifes, he brought feveral over to inllruft a number of youth, chofen from among the knights and people, in the dif¬ ferent kinds of acclamations pradlifed at Alexandria. Thefe continued in ufe as long as the reign of Theb- doric. But the people did not always make a fmgle chorus ; fometimes there were two,, who anfwered each other alternately: thus, when Nero played on the theatre, Burrhus and Seneca, who were on either hand, giving the fignal by clapping, 5000 foldiers called Augullals, began to chant his praife, which the fpeftators w-ere obliged to repeat. The whole was conduced by a mufic-maller called Mefochorus or Pau- farius.—rY\\c lionour of acclamations was chiefly ren¬ dered to emperors,.their children, and favourites ; and to the mag ill fates who prefided at the games. Per¬ fons of. dillinguiflied merit alfo fometimes received them, of which Quintilian gives us inllances in Cato and Virgil. The moll ufual forms were, Feliciter, Lon- giorem vitatn, Atmos /dices. The ablors themfelves, and they who gained the prizes, in the games of the circus, w'ere not excluded the honour of acclama¬ tions. To theatrical acclamations may be added thofe of the foldiery and the people in time of triumph. The victorious army accompanied their general to the capi¬ tol ; and,, among the verfes they fung in his praifes, fre¬ quently repeated, lo Triumphe, wffiich the people anfwered in the fame ftrain. It was alfo in the way of acclamation, that the foldiers gave their general the title of Imperator, after fome notable victory : a title which he only kept till the time of his triumph. The acclamations of the fenate were fomewhat more ferious than the popular ones ; but arofe from the fame principle, viz. a defire of pleafing the prince or his fa¬ vourites ; and aimed likewife at. the lame end, either to exprefs the general approbation and zeal of the com¬ pany, or to congratulate him on his victories, or to make him new proteftations of fidelity. Thefe accla¬ mations were ufually given after a report made by foms fenator,,to which the reft all expreffed their confent by crying Gmnes, Omn.es;: or elfe, uEquum:est, Jus- tum est. Sometimes they began with acclamations* and fometimes ended with them without.other debates. It was after this manlier that all the elections and pro¬ clamations of emperors, made by the fenate, were con- dubled ; fomething of which practice is ftill retained at modem eledlions of kings and emperors, where Vivat Rexy ACC r sS 1 ACC Acclama- Rex, Vive le Roy, and Long live the King, are cufto- tion- ( mary forms. » The Greeks borrowed the cuftom of receiving their emperors in the public places from the Romans. Luit- prand relates, that at a proceffion where he was pre- fent, they fung to the emperor Nicephorus, vow* it* ; that is, Many years : which Codin expreffes thus, by to 4-xwsiv to 7ro\uxe,,“,'’> or by to and the wiih or falutation by ■roxv^eo,, ddatio, and accufatio. For, firft, leave was of his work ; but when it was to be formed into CUPS ^cep|ai0lis defined to bring a charge againft one, which was called pojlulare: then he againft whom the charge was laid, was brought before the judge; which was called de¬ fer re, or nominis delatio : laftly, the charge was drawn up and prefented, which was properly the accufatio. The accufation properly commenced, according to Paedianus, when the reus or party charged, being in¬ terrogated, denied he was guilty of the crime, and fub- fcribed his name to the delatio made by his opponent. In the French law', none but the Procureur general, or his deputies, can form an accufation, except for precious vafes, they always chofe the acentetum which had no flaws or blemifties. ACEPHALI, or Acephalit.®,’a term applied to feveral fedls who refufed to follow fome noted leaden. Thus the perfons who refufed to follow either John of Antioch, or St Cyril, in a difpute that happened in the council of Ephefus, were termed Aeepbali, wnthout a head or leader. Such bifhops, alfo, as were exempt from the jurifdicb'on and difcipline of their patriarch, were ftyled Acephali.

ACER, the Maple or Sycamore Tree : a genus of the monoecia order, belonging to the polygamia clafs of plants; and ranking under the 23d Natural Order, Trihilatce.—The generic characters, both natural and effential, are: The Hermaphrodite calyx is an a- cute, coloured, one-leav’d perianthium, divided into five fegments, flat and entire at the bafe, and perfiftent: The corolla is five-petal’d, ovate, and expanding: The fiamina confift of eight Tubulated Ihort filaments ; the antherae Ample, the dull cruciform : The pijlillum has a comprefled germen, immerfed in the receptacle, which is convex, perforated, and large ; the ftylus is filiform ; the ftigmata are two, pointed, {lender,, and reflex: The pericarpium confifts of two or three capfuls unitr¬ ing at the bafe, roundifh, comprefled,, each terminated with a large membranous wing r The feeds are folitary and roundifh. The Male calyx, corolla, and Jla- mina, are the fame as in the hermaphrodite.: The pif- tilium has no germen. nor ftylus; the ftigma is bifid. [Nota. On the firft opening of the flower, the Jligma alone appears ; a few days after,, the Jlylus.—The her¬ maphrodite flowers on the fame umbel are frequently of two forts: the inferior ones feniinine, the antheras of which do not burft, but the piftillura quickly grows into a fruit: the fuperior ones mafculine, of which the antherae fcatter their pollen,, but the piftilla without in- ereafing fall off.] Species, 'with their afes and properties 1. The pfeudb-platanus, 'or fycamore, is a very large and beautiful tree, with broad leaves, divided into five lobes ferrated in their edges; of a dark-green colour on the upper fide, but paler and fomewhat hoary un¬ derneath ; the flowers are very fmall, and of a green- ifh white colour. The corolla of this fpecies is fcarcely diftinguifhable from the calyx, and the ft a- mina are long.. The fruit is large, and beautifully variegated with green and purple-. This fpecies is a native of Germany, but thrives very well in Great Britain, where it is frequent in plantations. It is very proper for making plantations near the fea, or fhelter- ing fuch as are already too near it; becaufe the fyca- more-tree refifts the fpray of the ocean much better than moft other trees. But it has this inconve¬ nience, that its leaves are devoured by infects, fo as to become full of holes, and very unlightly; which has caufed the planting of it to be much negledted of late. It has, however, long been confidered as a tim¬ ber tree in this country,' having been much ufed by the turners for wooden bowls, difhes, trenchers, &c.; but,, fince the cuftom of ufing earthern ware has become fo prevalent, its value for thofe purpofes has greatly de- creafed. There are two varieties, one with broad leaves and large keys, the other with variegated leaves. By tapping it: yields a liquor not unlike that of the birch-tree from which the Highlanders of Scotland fometimes make an agreeable and wholefome wine.. 2. The campeftris, or common maple, is too well known to need any particular defcription, as it grows very- frequently in hedge-rows in molt parts of Britain. The timber of the common maple is far fuperior to Acer, the beech for all the ufes of the turner. When itM the abounds with knots, as it frequently does, it is highly , efteemed by joiners for inlayings. It is alfo frequently employed for making mufical inftruments, on account of its lightnefs; and for the whitenefs of its wood was formerly, efteemed for making tables, &c. But the principal value of the maple is for underwood ; it be¬ ing of a quick growth, and affording good fuel. 3. The negundo, or Virginian afh-leaved maple, is a very ftrong {hooting tree ; and in Virginia, where it is a native, is one of the largeft trees of this kind. Its leaves are of a pale green, and well adapted to give a variety of tint 5 but Hanbury fays, that this tree ought not to be planted in expofed fituations, the branches being fubjeftto be fplit off by the. winds. Its ufes are fimilar to thofe of the fycamore.. 4. The platanoides, or Norway-maple, grows na-- turally in Norway, Sweden, and other northern coun¬ tries of Europe. It rifes to a good height, and is well furnifhed with branches with fmooth leaves, of a Ihining green colour, and beautifully indented.. Thefe.have an acrid milky juice,, which prevents them from being preyed- upon by infefts as the fycamore is ; and as this fpecies refifts the fpray of the fea equally with the firft, it is preferred in plantations fituated near the fea. In autumn the leaves dye to a golden yellow colour, which caufes a delightful effedt at thatfeafon when the different tints of decaying vegetables, are difplayed. The flow¬ ers are alfo beautiful; they come out early in the fpring,. are of a fine yellow colour, and Ihow themfelves. to ad¬ vantage before the leaves come out. They are frequently fucceeded by keys, which fometimes arrive at maturity in this country. There is a variety with ftriped leaves. 5. The rubrum, or Virginian fcarlet flowering maple, is a native of that country, and never grows to a large fize in Britain. It is, however,, cultivated, in gardens for the beauty of its flowers, which appear in the be- ■ ginning of April, imroundifti bunches, at the bottom of the footftalks of the leaves. The feeds, are ripe in five or. fix weeks after ; and ought to be immediately fown, being otherwife very apt to periih. The tree ought to be fheltered, efpecially whilft young, from tlie north-eaft winds; it delights in a moift light foil, where it will thrive much better,, as well as produce many more flowers, and much better feeds, than in a dry ground. A variety of this tree is known in England , by the name, of Sir Charles Wager's Flowering Maple^ from its being firft fent from America to Sir Charles, Wager. The flowers of this kind come out, in larger clufters than the other, and furround the fmall branches,, fo that the tree appears, entirely covered with them, and makes a much more beautiful appearance than the for-- mer, which is now not fo much efteemed. 6. The faccharinum, or fugar-maple, is-a large grow¬ ing tree ; will, arrive at the height of 40 feet; and has broad thin leaves, divided into five principal'parts which are again indented or cut at the edges into fe.- veral acute fegments. Their furface is fmooth, of a light green colour, whitilh underneath ; and they grow on pretty long footftalks. The flowers come out in the fpring, about the time of the Norway maple ; and they are fucceeded by long keys, which fometimes ripen. in England. In America, the inhabitants tap this tree in the fpring, boil the liquor, and the feces af¬ ford: . ACE T 61 1 ACE ■Acer, ford a ufeful fugar. The fycamore, the afli-leaved, and _ tlie the Norway maples, alfo abound with a faccharine juice, . a‘l J from which there is no doubt but a ufeful fugar might be prepared. 7. The Penfylvameum, or American mountain-maple, very much refembles the fugar-maple, only its leaves are more pointed. 8. The opalus, or Italian maple, is very common in moft parts of Italy, particularly about Rome ; but in Britain is very rarely to be met with, though hardy enough to bear the open air. It is one of the largeft fpecies of trees in Italy, and affords a great fhade by its numerous and large leaves. On this account it is planted on the road-fides, and near habitations. 9. The monfpefulanum, or Montpelier maple, is .common in the fouth of France, and in Italy ; but is hardly met with in Britain. The leaves refemble thofe of the common maple but are of a much thicker fub- ftance, a fhining green colour, and not fo large. They continue in verdure very late in the autumn, which renders the trees more valuable. 10. The creticum, or Cretan maple, grows natural¬ ly in the Levant; it fomewhat refembles the laft fpe¬ cies ; but its leaves are of a much thinner texture, and their footftalks covered with a foft hairy down ; where¬ as thofe of the other are fmooth and foft. Propagation and culture.]-—i. By feeds. The fir ft four fpecies are eafily propagated in this way. The keys, when ripe in autumn, may be gathered, and- in a few days after fown, about an.inch and an half deep, in beds of common mould. In fpring the plants will ap¬ pear, and make a fhoot of about a foot and an half by the autumn following,, if the ground of the femi- nary be tolerably good, and they are kept free from breeds. The fpring after they come up they fhould be planted in the nurfery in rows two feet and an half afunder; and their diftance in the rows nmft be one foot and an half. Here they may remain till they are big enough to plant out finally, with no further trouble than taking off unfightly fide-branches, and fuch as have a tendency to make the tree forked, except digging be¬ tween the rows, which mull always be done every winter. For the other fpecies, their feeds, as they do not ripen in this country, ought to be procured from the places where they naturally grow, and managed in the following manner : A cool ftiady part of the femi- nary firould be appropriated for the purpofe ; the mould fhoul&be made fine ; beds fliould be marked out four feet wide,, and in length proportionable to the quantity; and in thefe the feeds fhould be regularly fown, lifting over them abouthalf an inch of the fineft mould. When the plants come up, they mull be kept clean from weeds, and frequently watered ; and this work muft be duly at¬ tended to all fummer.. The next fpring, the flrongell ■ may be drawn out, and planted in the nurfery, in rows two feet afunder, and at the diftance of a foot from each other in the rows; leaving-the others in the feminary to gain ftrength. The fpring following they alfo muft receive the fame culture ; and in the nurfery they may remain, with no other trouble than keeping the ground clean from weeds in the fummer, digging between the rows in the winter, and taking off all ftrong and irre¬ gular fide-fhoots till they are planted out. Trees raifed from feeds will grow fafter, and arrive at greater height, than thofe raifed from layers : but they will not pro¬ duce fuch quantities of flowers; which makes the latter Acer, method more eligible for thofe who want thefe plants ^ for a low ftirubbery.—Seeds of the variegated kinds al- "i ' ^ I fo, when fown, will produce variegated plants in return; which renders the propagation of thefe forts very expe¬ ditious where plenty of feeds may be had. Where thefe are not to be obtained, the plants are propagated by budding, as afterwards diredled. 2. By layers. All the fpecies may be propagated by this method; though it is never pradlifed for the com¬ mon maple and the fycamore. The young ftioots may be at any time laid down in the autumn, winter, or early in the fpring. By the autumn following, they will have ftruck root, and Become good plants ; when the ftrongeft may be fet out in the places where they are'to remain ; whilft the weakeft may be planted in the nurfery, like the feedlings,. for a year or two, to acquire ftrength.- 3. By cuttings : which method, however, is chiefly practifed on the afh-leaved and Norway maples, which more readily take root this way. The cuttings fliould be the bottom parts of the laft year’s (hoots: They fliould be taken off earjy'in Odlober, and planted in rows in a moift ftiady place. The fpring and fummer following, they muft be duly watered as often as dry weather makes it neceflary, and be kept clean from weeds. By the autumn they will be fit to remove into the nurfery ; though if the cuttings are not planted too clofe, they may remain in their fituation for a year or two longer, and then be fet out. finally, w-ithout- the trouble of being previoufly planted in the nurfery. 4. By budding, grafting, and inarching. Thefe methods are only practifed for the variegated forts and the large broad-leaved kind- The latter is to be conti¬ nued no otherw-ife than by budding it on flocks of the common fycamore ; for from , the feeds, though fo large themfelves, only the common fycamore is-produced. In order to propagate thefe varieties by budding,, let fome plants of the common fycamore, one year old, be taken out of the feminary, and fet in the nurfery in rows a yard afunder, and the plants about a foot and a, half diftance from each other in the rows: Let the ground be kept clean from weeds all fummer, and turned in in the winter; and the fummer following the flocks will be of a proper fize to receive the buds, which fhould be taken from- the moft beautifully-ftriped branches. The bed time for this work is the middle or latter end of Auguft. Having then budded your (locks with the eyes or buds fronting the north, early in Oc¬ tober take off the bals-matting, which before this time will have confined the bark and pinched the bud, but1 not fo as to hurt it much. Then cut off the flock- juft above the bud, and dig the ground between the rowrs. The fummer following, keep the ground clean from weeds; cut off all natural fide-buds from the flock as they come out; and by autumn, if the land is good, the buds will have (hot forth, and formed themfelves into trees five or fix feet high. They may be then re¬ moved into the places where they are deftgned to re¬ main ; or a few of them only may be drawn out, lea¬ ving the. others to be trained up for larger ftandards. Theftriped Norway maple (hould be budded on (locks of its own kind ; for on thefe they take beft, and both kinds are not very, liable to run away from their co¬ lours.

ACERRA, in antiquity, an altar erected, among the Romans, near the bed of a perfon deceafed, on which his friends daily oftei jd incenfe till his burial.— The real intention probably was to overcome any offen- ;five fmell that might arifc about the corpfe. The Chi- nefe have ftill a cuftom like this : they ere ft an altar •to the deceafed in a room hung vith mourning; and place an image of the dead perfon on the altar, to which every one that approaches it bows four times, and of¬ fers oblations and perfumes. The Acerra alfo fxgnified a little pot wherein were put the incenfe and perfumes to be burnt on the altars of the gods and before the dead. It appears to have been the fame with what was otherwife called thuribu- lum, and pyxis. We find mention of Acerree in the ancient church. The Jews had alfo their Acerrce, in our verfion render¬ ed confers; and the Romanifts ftill retain them under the name of incenfe-pots. In Roman writers, we fre¬ quently meet with plena acerra, a full acerra: to un- derftand which, it is to be obferved, that people were obliged to offer incenfe in proportion to their eftate and condition ; the rich in larger quantities, the poor only a few grains; the former poured out acerras full on the altar, the latter took out two or three bits with their fingers.

This republic was not con* fiderable 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, itsjuftice, and its love of liberty. Its high reputation for thefe virtues was very ancient. The Crotonians and Sybarites, to re-eftablilh order in their towns, adopted the laws and cuftoms of the Achaeans. After the famous battle of Leuftra, a difference arofe betwixt the Lacedaemonians and Thebans, who held the virtue of this people in fuch veneration, that they terminated the difpute by their decifion. The government of the Achaeans was democratical. They preferved their liberty till the time of Philip and Alexander: But in the reign of thofe princes, and afterwards, they were either fubjefk to the Macedonians, who had made themfelves mafters of Greece, or oppreffed by cruel tyrants. The Achaean commonwealth confifted of twelve inconfiderable towns in Peloponnefus. Its firft annals are not marked by any great aftion, for they are not graced with one eminent chara&er. After the death of Alexander, this little republic was a prey to all the evils which flow from po¬ litical difeord. A zeal for the good of the community was now extinguiflied. Each town was only attentive to its private intereft. There was no longer any liabi¬ lity in the ftate ; for it changed its mafters with every revolution in Macedonia. Towards the 124th Olym¬ piad, about the time when Ptolemy Soter died, and when Pyrrhus invaded Italy, the republic of the A- chasans recovered its old inftitutions and unanimity. The inhabitants of Patas and of Dymae were the firft; afferters of ancient liberty. The tyrants were banilh- ed, and the towns again made one commonwealth. A public council was then held, in which affairs of importance were difeuffed and determined.

ACHiEMENES, according to Herodotus, was fa¬ ther of Cambyfes, and grandfather of Cyms the firft, king of Perfia. , Moft of the commentators of Horace are of opinion, that the Achasmenes whom that poet mentions, ode xii. of his 2d book, was one of the Per- fian monarchs: but, if that were true, he muft have reigned before the Medes fubdued the Perfians; for we do not hear of any king of that name from the time that the Perfians founded that great monarchy, which is looked upon as the fecond univerfal one. However this be, the epithet Achannenians is frequently given to the Perfians, in the old Latin poets. Achjemenes, fon .of Darius I. king of Perfia, and brother of Xerxes, had the government of Egypt be¬ llowed on him, after Xerxes had forced the Egyptians to return to their allegiance. He fome time after com¬ manded the Egyptian fleet in the celebrated expedition which proved fo fatal to all Greece, The Egyptians having again taken up arms after the death of Xerxes, Aehsemenes was fent into Egypt to fupprefs the rebel¬ lion ; but was vanquifhed by Inarus, chief of the rebels, fuccoured by the Athenians. ACHiEUS, coufin-german to Seleucus CeraUnus and Antiodhus the Great, kings of Syria, became a very powerful monarch, and enjoyed the dominions he had ufurped for many years ; but at laft he was pu- niflied for his ufurpations in a dreadful manner, in the * Lib. viii. 14.0th year of Rome, as related by Polybius*, cap. 5. 6. ACHAIA, a name taken for that part of Greece which Ptolemy calls Hellas; the younger Pliny, Gra¬ cia; now called Livadia: bounded on the north by Theflaly, the river Sperchius, the Sinus Maliacus, and mount Oeta ; on the weft by the river Achelous ; on the eaft, turning a little to the north, it is walked by the Archipelago, down to the promontory of Sunium ; on the fouth, joined to the Peloponnefus, or Morea, by the ifthmus of Corinth, five miles broad.

In this dreadful exigence, Jofhua proftra- ted himfelf before the Lord, and begged that he would have mercy upon his people.

ACHEEN, Ache', or Ac hen-, a kingdom of Su-- matra in the Eaft-Indies, lituated on the north-weftern. part of the ifland. The capital is fituated on a river which empties it- felf near the north-weft point, or Acheen-head, about: two miles .from the mouth. It lies in a wide valley,, formed.! A C H [ 64 ] A C H Acfteen. formed like an amphitheatre by two lofty ranges of hills. The river is not large, and by emptying itfelf in feveral channels is rendered very (hallow at the bar. In the dry monfoon it will not admit boats of any burthen, much lets large veffels, which lie without, in the road formed by the iflands off the point. Though no long¬ er the great mart of eaftern commodities, it ftill carries on a confiderable trade with the natives of that part of the coaft of Indoftan called Telinga, who fupply it with the cotton goods of their country, and receive in re¬ turn, gold-duff, fapan-wood, betel-nut, patch-leaf (col- fus Jndicus), a little pepper, fulphur, camphire, and benzoin. The country is fupplied with Bengal opi¬ um, and alfo with iron, and many other articles of ^merchandize, by the European traders. Acheen is efteemed, comparatively, healthy, being more free from woods and fwamps than moft other por¬ tions of the iflandand the fevers and dyfenteries to which thefe are fuppofed to give occafion, are there laid to be uncommon. The foil is light and fertile; and the produfts, befide thofe already enumerated as articles of export trade, and a variety of line fruits, are chiefly rice and cotton. There is likewife feme raw filk procured in the country, of very inferior quality. Gold duff is collefted in the mountains near Acheen, but the greateft part is brought from the fouthern ports of Nalaboo and Soofoo. The fulphur is gathered from a volcano mountain in the neighbourhood, which fup- plies their own confumption for the manufafture of gun-powder, and admits of a large exportation. In their perfons, the Achenefe differ from the reft of the Sumatrans, being taller, ftouter, and darker com- plexioned. They appear not to be a genuine people; but are thought, with great appearance of reafon, to be a mixture of Battas, Malays, and Moors from the weft of India. In their difpofitions they are more aftive and induftrious than their neighbours; they poffefs more penetration and fagacity ; have more general know¬ ledge ; and as merchants, they deal upon a more exten- live and liberal, footing. Their religion is Mahometa- nifm ; and having a great number of mofques and priefts, its forms and ceremonies are ftridlly obferved. The appearance of the town, and the nature of the buildings, are much the fame as are found in the ge¬ nerality of Malay bazars, excepting that the fuperior wealth of this place has occaffoned a great number of public edifices, but without the fmalleft pretenfions to magnificence. The king’s palace, if it deferves the appellation, is a very rude and uncouth piece'of archi- tefture, defigned to refill the force of an enemy, and furrounded for that purpofe by ftrong walls, but with¬ out any regular plan, or view to the modern fyftem of military attack. The houfes in common are built of bamboos and rough timber, and raifed fome feet from the ground on account of the place being overflowed in the rainy feafon. A confiderable fabrick of a thick fpecies of cotton cloth, and of fluff for the Ihort drawers worn both by Malays and Achenefe, is eftablilhed here, and fupplies an extenfive demand. They weave alfo very handfome filk pieces, of a particular form, for that part of the drefs which is called by the Malays cayen farrong. The Achenefe are expert and bold navigators, and employ a variety of veffels, according to the No. 2. 1 voyages they undertake, and the purpofes for which Acheen, they defign them. The river is covered with a mul- " titude of filhing fampans or canoes, which go to fea with the morning breeze, and return in the afternoon, with the fea wind, full laden. Having no convenient coins, though moft fpecies of money will be taken there at a valuation, they com¬ monly make their payments in gold dull, and for that purpofe are all provided with fcales or fmall lleelyards. They carry their gold about them, wrapped up in pieces of bladder, and often purchafe to fo fmall an a- mount, as to make ufe of grain or feeds for weights. The monarchy is hereditary ; and the king ufually maintains a guard of zoo Seapoys about his palace. According to Mr Marfden, “ the grand council of the nation confifts of, the King or Sultan, four Oolooballangs, and eight of a lower degree, who fit on his right hand, and fixteen Cajoorangs, who fit on his left. At the king’s feet fits a woman, to whom he makes known his pleafure: by her it is communicated to an eunuch, who fits next to her, and by him to an officer named Cajoorang Gon- dong, who then proclaims it aloud to the affembly. There are alfo prefent two other officers, one of whom has the government of the bazar or market, and the other the fuperintending and carrying into execution the punifhment of criminals. All matters relative to commerce and the cuftoms of the port come under the jurifdiclion of the Shabandar, who performs the ce¬ remony of giving the chap or licence for trade ; which is' done by lifting a golden-hafted creefe over the head of the merchant who arrives, and without which he dares not to land his goods. Prefents, the value of which are become pretty regularly afcertained, are then fent to the king and his officers. If the ftranger be in the ftyle of an ambaffador, the royal elephants are fent down to carry him and his letters to the monarch’s prefence ; thefe being firft delivered into the hands of an eunuch, who places them in a filver dilh, covered with rich filk, on the back of the largeft elephant, which is provided with a machine {header) for that purpofe. Within about an hundred yards of an open hall where the king fits, the cavalcade Hops, and the ambaffador difmounts, and makes his obeifance 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 fhoes; and having made a fe- cond obeifance, is feated upon a carpet on the floor, where betel is brought to him. The throne was fome years ago of ivory and tortoifelhell, and when the place was governed by queens, a curtain of gauze was hung before it, which did not obftruft the audience, but pre¬ vented any perfeft view. The ftranger, after fome ge¬ neral difeourfe, is then conducted to a feparate build¬ ing, where he is entertained with the delicacies of the country, by the officers of Hate, and in the evening re¬ turns in the manner he came, furrounded by a prodi¬ gious number of lights.

Achen was vifited by the Portuguefe in 1509, only 12 years after they had difcovered the paffage to the Eaft-Indies by the Cape of Good Hope. They made various attempts to eftablifli themfelves in the country, but were expelled with difgrace. Scc Summatra. ACHELOUS, in fabulous hiftory, wreftled with Hercules, for no lefs a prize than Deianira, daughter to king Genus : but as Achelous had the power of af- fuming all lhapes,the conteft was long dubious : at laft, as he took that of a bull, Hercules tore off one of his horns ; fo that he was forced to fubmit, and to redeem it by giving the conqueror the horn of Amalthea, the fame with the Cornucopia or horn of plenty ; which Hercules having filled with a variety of fruits, confe- crated to Jupiter. Some explain this fable, by faying, That Achelous is a winding river of Greece, whofe ftream was fo rapid, that it roared like a bull, and over- from north to fouth. Acheron, or Acheros, a river of the Bruttii in Italy, running from eaft to weft; where Alexander king of Epirus was flain by the Lucani, being decei¬ ved by the oracle of Dodona, which bid him beware of Acheron.

The former takes it to be an effufion, exundation, or wafties of the fea, and there¬ fore called by Lycophron, Acacia —■ Alfo a lake of Epirus, through which the Acheron runs.—There is alfo an Acherujia, a peninfula of Bithynia on the Euxine, near Heraclea ; and a cave there of the fame flowed its banks; but Hercules, by bringing it into name, through which Hercules is fabled to have de- two channels, broke off one of the horns, and fo refto- red plenty to the country. See the next article. Achelous, a river of Acarnania; which rifes in mount Pindus, and, dividing iEtolia from Acarnania, falls from north to * fouth into the Sinus Corinthiacus. It was formerly called Thoas, from its impetuofity, and king of rivers, (Homer.) The epithet Acheloius is ufed for Aqueus, (Virgil); the ancients calling all water fcended to hell to drag forth Cerberus. ACHIAR, is a Malayan word, which fignifies all forts of fruits and roots pickled with vinegar and fpice. The Dutch import from Batavia all forts of achiar, but particularly that of Bamboo (fee Arundo), a kind of cane, extremely thick, which grows in the Eaft Indies. It is preferved there, whilft it is ftill green, with very ftrong vinegar and fpice ; and is Achelous, efpecially in oaths, vows, and facrifices, accor- called bamboo-achiar.

ACHILLiEA, Yarrow, Milfoil, Nosebleed, or. Sneezewort ; a genus of the order of thepolyga- mia fuperflua, belonging to the fyngenefia clafs of plants. The natural order to which it belongs is the 49th, Compojitx difcoides. The characters are: The common calyx is ovate and imbricated, with ovate, acute, converging fcales. The compound corolla is rayed ; the hermaphrodite co- rollets are tubular in the difc, the feminine lingui- form and from 5 to 1 o in the rays : The proper co¬ rolla of the hermaphrodites is funnel-lhaped, expanded, and divided into 5 fegments; that of the females, tongue-fhaped, inverfely cordated, expanding, and of 3 fegments. The Jlamina in the hermaphrodites con- fift of 5 very ftiort capillary filaments; the anthera is cylindric and tubular. The pijlillum in the hermaphro¬ dites has a fmall germen ; the ftylus is filiform the length of the ftamina ; the ftigma is obtufe and end- notched : in the females, the germen is fmall; the fty¬ lus is filiform ; the ftigmata are 2, obtufe and refle&ed. The pericarpiu?n is wanting ; the calyx fcarcely chan¬ ged ; the receptacle filiform, elongated at the difc of the feeds, ovate, and twice as long as the calyx. The feeds are folitary, ovate, and furnifhed with a lock of wool; no pappus. The reccptaculum is chaffy and ele¬ vated. Species and properties. There are 20 fpecies, of which the following are the principal: 1. The mil¬ lefolium, or common yarrow, is found naturally on banks, and by the fides of foot-paths, in moft parts of England. It moft commonly bears white flowers, though a variety of it is found which bears purple ones. Thefe, however, do not long continue to bear flowers of this colour, if tranfplanted into gardens. It was formerly ufed in medicine; but though itmayilillhave a place in fome difpenfatories, no phyfician of any note expefts any virtue from it, or ever prefcribes it. It creeps greatly by its roots, and alfo multiplies by the feeds, fo that it becomes a troublefome weed where it is once allowed to get a footing. The'cultivation of it is recommended by Mr Anderfon, in his Effays on A- griculture, as a proper food for cattle. This fpecies was the proper achillsea of the ancients, fo named from Achilles; who, having been the difciple of Chiron, firft brought it into ufe for the cure of wounds and ulcers. 2. The fantolina, or eaftern fneezewort, is fometimes cultivated in gardens; it has large yellow flowers, which ftand upon pretty long footftalks placed fingly, not in bunches as in the common kind. It has leaves like lavender-cotton, which, when rubbed, emit a ftrong oily odour. The flowers appear in June and July. 3. The tomentofa, or woolly yarrow, is a native of the fouth of Trance and Spain, but lives in the open air in England. The flowers are of a bright yellow, and continue long in beauty, growing in .clutters at the top of the ftalks, which feldom rife above a foot high. The leaves are finely cut, and very hoary. 4. The abrotanifolia, or tall eaftern yarrow, is a native of the iflands in the Ar¬ chipelago : it grows to the height of two feet and a half, with large umbels of yellow flowers on the top ; the leaves refemble thofe of the common wormwood, and are cut into long narrow fegments. 5. The cla- venna, or Alpine umbelliferous wormwood, takes its Achillsa. name from the mountains of which it is a native. It feldom grows above fix or feven inches in height; it fupports umbels of white flowers, like thofe of the com¬ mon fneezewort, which appear in April and May. The leaves are filvery, and fhaped like thofe of wormwood, which often decay in the autumn and winter. 6. The tanacetifolia, or eaftern fneezewort, with tanfey leaves, is a very humble plant, feldom rifing above fix inches in height. The flowers are .nearly as large as thofe of the common fneezewort, white, and growing in flat umbels. They appear in June and July. The leaves of the1 plant have fome likenefs to thofe of the common wormwood, are very hoary, grow clofe to the ground,, and decay in autumn fo as to make little appearance in winter. Like the laft fpecies, this is a native of the Alps. 7. The ageratum, or fweet maudlin, was formerly much ufed in medicine and for culinary pur- pofes, but has now fallen fo much into negleft as to be totally unknown in the markets; fo that when it is demanded, the white maudlin is fubftituted in its ftead. The reafon of this fubftitution was, that the latter is more hardy and eafily propagated than the fweet maud¬ lin, which is apt to rot in wet winters. The common maudlin flowers in June and July, and the feeds are ripe in September. 8. The Egyptiaca, or hoary fneeze¬ wort, is a native of the Archipelago. It hath very hoary leaves, which remain all the year and the plants growing clofe and low, make a pretty appearance at all feafons. The flowers are yellow, and are produced in umbels on the top of the ftalks; they appear in June, and continue till the end of September. 9. The ptarmi- ca, or common fneezewort, grows wild in the woods, and other fliady places, in many parts of England; fo is not admitted into gardens. There is a variety, however, with double flowers, which is preferved in gardens, and is commonly known by the name of double maudlin. This fpecies creeps greatly by the roots, fo as foon to overfpread a large fpot of ground. If planted in- pots, fo as to confine its roots from creeping, the ftalks grow clofe together, and make a tolerable appearance when in flower; but when at a diftance, fo that the roots have full liberty to run, the flowers appear but indifferently. 10. The macrophylla, or Alpine fneeze¬ wort, with feverfew leaves, is a native of the Alps. It produces many ftalks rifing near three feet high ; ha¬ ving loofe branching umbels of white flowers on their top, refembling thofe of the common fneezewort, but larger. 11. The nana, or hoary Alpine milfoil, is like- wile a native of the Alps ; the leaves are hoary, and the umbels of its flowers are more compaft than the former; the ftalks do not rife more than a foot high. 12. The nobilis, or fweet milfoil, approaches to the nature of the common milfoil; but its leaves are of a paler green, and are neither fo long nor fo much cut off as thofe of the common milfoil are: they have a ftrong fweet fcent when bruifed. 13. The alpina, or white maudlin, bears fome refemblance to the common fneezewort; but the leaves are longer, of a deeper green colour, and deeply indented in their edges; the flowers are white, and the roots creep far under ground. The plant will rife, in good land, to the height of four feet. Culture. All the forts of yarrow are eafily propa¬ gated by feeds, which may be fown either in the fpring A C H [ 67 ] A C H Achilleid, or autumn, upon a bed of common earth. When the , Achilles. ^ plants COme up, and are ftrong enough for tranfplant- v ing, they fiiould be planted in beds in the nurfery, where they may continue till autumn, when they fhould be tranfplanted to the places where they are to remain. The Archipelago kinds, however, are often deftroyed by fevere froft ; fo they ought to be flickered during the winter. Thefe kinds alfo rarely bring their feeds to perfection in England ; they are therefore to be pro¬ pagated by flips, which may be taken off and plant¬ ed in a fliady border any time in fummer, when they will take root in about fix weeks, and then may be tranfplanted where they are to remain. ACHILLEID, Achilleis, a celebrated poem of Statius, in which that author propofed to deliver the whole life and exploits of Achilles ; but being prevent¬ ed by death, he has only treated of the infancy and e- ducation of his hero. See Statius. ACHILLES, one of the greatcft. heroes of ancient Greece, was the fon of Peleus and Thetis. He was a native of Phthia, in Theffaly. His mother, it is faid, in order to confume every mortal part of his body, ufed to lay him every night under live coals, anointing him with ambrofia, which preferved every part from burn¬ ing but one of his lips, owing to his having licked it. She dipped him alfo in the waters of the river Styx; by which his whole body became invulnerable, except that part of his heel by which flie held him. But this opinion is not univerfal, nor is it a part of his charac¬ ter as drawn by Homer; for in the Iliad (B. xxi. 161.) he is actually wounded in the- fight arm, by the lance of Afteropaus, in the battle near the river Scamander. Thetis afterwards intrufted him to the care of the cen¬ taur Chiron, who, to give him the llrength neceffary for martial toil, fed him with honey and the marrow of lions and wild boars. To prevent his going to the fiege of Troy, flie difguifcd him in female apparel, and hid him among the maidens at the court of king Lycomedes: but Ulyffes difcovering him, perfuaded him to follow the Greeks. Achilles diftinguiflied him- felf by a number of heroic aftions at the fiege. Being difgutted, however, with Agamemnon for the lofs of Brifeis, he retired from the camp. But returning to avenge the death of his friend Patroclus, he flew Hec¬ tor, faftened his corps to his chariot, and dragged it round the walls of Troy. At laft Paris, the brother of Hettor, wounded him in the heel with an arrow, while he was in the temple treating about his marriage with Philoxena, daughter to king Priam. Of this wound he died, and was interred on the promontory of Sigasum ; and after Troy was taken, the Greeks facri- ficed Philoxena on his tomb, in obedience to his defire, that he might enjoy her company in the Elyfian fields. It is faid, that Alexander, feeing this tomb, honoured it by placing a crown upon it; at the fame time, cry-; ing out, that “ Achilles was happy in having, during his life, fuch a friend as Patroclus; and, after his death, a poet like Homer.” Achilles is fuppofed to have died 1183 years before the Chriftian asra. Achilles Tatius. See Tatius. Tendo AchiluS) in anatomy, is a ftrong tendinous cord formed by the tendons of feveral mufcles, and in- ferted into the os calcis. It has its name from the fa-, tal wound Achilles is faid to have received in that part from Paris the fon of Priam. ACHILLINI (Alexander), born at Bologna, and Achilllni doftor of philofophy in that univerfity. He flourilhed Acj^iet. in the 15th and 16th centuries, and by way of eminence , ^ ; was ftyled the Great Philofopher. He was a ftedfaft follower and accurate interpreter of Averroes upon Ari- ftotle, but moft admired for his acutenefs and ftrength of arguing in private and public deputations. He made a furprifing quick progrefs in his ftudies, and was very early promoted to a profefforfhip in the univerfity ; in which he acquitted himfelf with fo much applaufe that his name became famous throughout all Italy. He con¬ tinued at Bologna till the year 1506 ; when the uni¬ verfity of Padua made choice of him to fucceed Anto¬ nio Francatiano in the firft chair of philofophy, and his fame brought vaft numbers of ftudents to his lec¬ tures at Padua : but the war, wherein the republic of Venice was engaged againft the league of Cambray, putting a flop to the ledtures of that univerfity, he withdrew to his native country ; where he was received with the fame marks of honour and diftindtion as be¬ fore, and again appointed profeffor of philofophy in Bologna. He fpent the remainder of his life in this city, where he died, and was interred with great pomp in the church of St Martin the Great, which belongs to the Carmelite friars. Jovius, who knew Achillini, and heard his ledtures, fays, that he was a man of fuch ex- ceeding fimplicity, and fo unacquainted with addrefs and flattery, that he was a laughing-ftock to the pert and faucy young fcholars, although efteemed on account of his learning. He wrote feveral pieces on philofo- phical fubjedts, which he publiftied, and dedicated to John Bentivogli. Achillini (Claudius), grandfon of the former, read ledtures at Bologna, Ferrara, and Parma ; where he was reputed a great philofopher, a learned divine, an excellent lawyer, an eloquent orator, a good mathe¬ matician, and an elegant poet. He accompanied Car¬ dinal Ludovino, who went as legate into Piedmont; but being afterward negledled by this cardinal, when he became pope under the name of Gregory XV. he left Rome in difguft, and retired to Parma; where the duke appointed him profeffor of law, with a good falary. He publiflied a volume of Latin Letters, and another of Italian poems, which gained him great reputation : he died in 1640, aged 66. ACHIOTTE, orAcHioTL, a foreign drug, ufed in 'dying, • and in the preparation of chocolate. It is the fame with the fubftance more ufually known by the name of Arnotto ; which fee, ACHIROPCETOS, a name given by ancient wri¬ ters .to certain miraculous pictures of Chrift and the Virgin, fuppofed to have been made without hands.— The moft celebrated of thefe is the picture of Chrift, preferved in the church of St John Lateran at Rome ; faid. to have been begun by St Luke, but finiflied by the miniftry of angels. ACHMET, fon of Seerim, has left a book concern¬ ing the interpretation of dreams according to the doc* trine of the Indians, Pferfians, and Egyptians, which was tranflated out of Greek into Latin by Leo Tuf- cus in 1160. He lived in the 9th century. ACHMET GEDUC, a famous general under Ma¬ homet II, and Bajazet II. in the 15th century. When Mahomet II. died, Bajazet and Z-ezan both claimed the throne : Achmet fided with the former, and by his I 2 bravery A C H [ 68 ] A C H Aehmet- bravery and conduft fixed the crown on his head. But Achmi'm ®ajazet t0°k away his life; Ihining virtue being always ^ an unpardonable crime in the eyes of a tyrant. AChJMETSCHET, a town of the peninfula of the Crimea, the refidence of the fultan Galga, who is eldeft fon of the Khan of Tartary. Long. 51. 20. Lat. 45. o. ACHMIM, a large town of Upper Egypt, fituated on the eaftern bank of the Nile. “ One admires there (fays Abulfeda, as quoted by Mr Savary) a temple, which is comparable to the moft celebrated monuments of antiquity. It is conftrufted with. Hones of a furpri- fing fize, on which are fculptured innumerable figures.” Though this town be fallen from its ancient fplendor, it is ftill one of the mofl; beautiful of Upper Egypt. According to Mr Savary, an Arab prince commands there, and the police is well attended to. The ftreets are wide and clean, and commerce and agriculture flou- rifh. It has a manufactory of cotton, fluffs, and pot¬ tery, which are conveyed over all Egypt. It is the fame that Herodotus calls Cbemmis, and Strabo Pano- polis, or the city of Pan, who was worlhipped there. Herodotus fays, that Perfeus was a native of this city, and that his defcendants had eftablifhed feftivals there in his honour. It has loft its ancient edifices, and much of its extent; the ruins of the temple, defcribed by Abulfeda, being without its; limits, to the north. No¬ thing remains of it but fome ftones, of fuch magnitude that the Turks have not been aisle to move them. They are covered with hieroglyphics. On one of them are traced four concentric circles, in a fquare. The inner- moft of thefe contains a fun. The two fucceeding ones, divided into 12 parts, contain, one, 12 birds, the other, 12 animals almoft effaced, which appear to be the figns of the zodiac. The fourth has no divifions, and pre- fents 12 human figures ; which Mr Savary imagines to reprefent the 12 gods, the 12 months of the year, and the 12 figns of the zodiac. The Egyptians, fays He¬ rodotus, are the firft who divided the year into 12 months, and employed the names of the 12 gods. The four feafong occupy the angles of the fquare, on the fide of which may be diftinguifhed a globe with wings. Mr Savary thinks it probable that this ftone belonged to a temple dedicated to the fun, that the whole of thefe hieroglyphics mark his paffage into the figns of the zodiac, and his courfe, whole revolution forms the year. The columns of this temple have been partly broken to make lime and millftones. Some of them have been tranfported into one of the mofques of Ach- mim, where they are placed without tafte ; others are heaped up in the fquares of the town. Mr Savary tells us of a ferpent which is wor¬ lhipped here, and is the wonder of the country. “ Upwards of a century ago (fays he), a religious Turk called Scheilk Haridi died here. He paffed for a faint among the Mahometans; who railed a monument to him, covered with a cupola, at the foot of the mountain. The people flocked from all parts to offer up their prayers to him. One of their priefts, profiting by their credulity, perfuaded them that God had made the foul of Scheilk Haridi pafs into the body of a ferpent. Many of thefe are found in the Thebais, which are harmlefs ;- apd he had taught one to obey his voice. He appeared with his ferpent, dazzled the vulgar by his furprifing tricks, and pretended to cure all diforders. Some lucky in- Achmim ftances of fuccefs, due to nature alone, and fometimes Acjlras to the imagination of the patients, gave him great ce-, ‘ , lebrity. He foon confined his ferpent Haridi to the tomb, producing him only to oblige princes and per- fons capable of giving him a handfome recompence. The fucceflbrs of this prieft, brought up in the fame principles, found no difficulty in giving fanClion to fo advantageous an error. They added to the general perfuafion of his virtue that of his immortality. They had the boldnefs even to make a public proof of it. The ferpent was cut in pieces in prefence of the Emir, and placed for two hours under a vafe. At the inftant of lifting up the vafe, the priefts, no doubt, had the addrefs to fubftitute one exactly refembling it. A miracle was proclaimed, and the immortal Haridi acquired a frefli degree of confideration. This knavery procures them great advantages. The people flock from all quarters to pray at this tomb ; and if the ferpent crawls out from under the ftone, and approaches the fuppliant, it is a fign that his malady will be cured. It may be imagined, that he does not appear till an offering has been made proportioned to the quality and riches of the different perfons. In extraordinary cafes, where the fick per- fon cannot be cured without the prefence of the fer¬ pent, a pure virgin muft come to folicit him. To avoid inconveniences on this head, they take care to choofe a very young girl indeed. She is decked out in her beft clothes, and crowned with flowers. She puts herfelf in a praying attitude ; and as the priefts are inclined, the ferpent comes out, makes circles round the young fuppliant, and goes and repofes on her. The virgin, accompanied by a vaft multitude, carries him in tri¬ umph amidft the general acclamation, No human reafoning would perfuade thefe ignorant and credulous Egyptians that they are the dupes of a few impoftors ; they believe in the ferpent Haridi as firmly as in the prophet.” ACHONRY, a fmall town of Ireland, in the pro¬ vince of Connaught and county of Sligo, feated on the river Shannon. ACHOR, a valley of Jericho, lying along the river Jordon, not far from Gilgal; fo called from Achan, the troubler of Ifrael, being there ftoned to death. Achor, in medicine, a fpecies of Herpes. Achor, in mythology, the god of flies; to whom, according to Pliny, the inhabitants of Cyrene facrifi- ced, in order to obtain deliverance from the infefts and the diforders occafioned by them. ACHRADINA (anc. geog.), one of the four ci¬ ties or divifions of Syracufe, and the ftrongeft, largeft, and moft beautiful part of it; feparated by a very ftrong wall from the outer town, Tycba and Neapolis. It was adorned with a very large forum, with beautiful por¬ ticos, a moft elegant prytaneum, a fpacious fenate- houfe, and a fuperb temple of Jupiter Glympius. ACHRAS, or Sapota Plum: a genus of the mo- nogynia order, belonging to the hexandria clafs of plants; and ranking in the 43d Natural Order, Du- mofte. The characters are: The calyx is a perianthium, confifting of fix ovate concave ere ft leaflets, the ex¬ terior ones broader and fhorter, the interior ones co¬ loured. The corolla is compofed of one ovate petal, the height of the calyx ; the border divided into fix fegments- A G H [ 69 ] A C I Achras fegments. The Jlamina have fix fliort Tubulated fila- ments at the throat of the corolla ; and the anther# thL " are acut;e- The pijlillium has a roundifli depreffed ger- —men ; the ftylus is Tubulated, and longer than the corolla; the ftigma is obtufe. The pericarpium is a globular twelve-celled pomum, with very Toft flefh. The feeds are folitary, ovate, and gloffy. There are four fpecies, all natives of the Weft In¬ dies. The principal are, 1. The fapota, with oblong oval leaves, and fmooth turbinated fruit. 2. The mam- mofa, with fpear-lhaped leaves, and large oval fruit. The firft is common about Panama, and fome places in the Spanifti Weft Indies; but is not to be found in any of the Britifh fettlements in America. The fe- cond fort is very common in Jamaica, Barbadoes, and moft of the Weft India iflands, where the trees are planted in the gardens for their fruit, which is by many perfons greatly efteemed. They grow to the height of 35 or 40 feet, having a ftraight trunk covered with an afh-coloured bark. The branches are produced on e- very fide, forming a regular head ; and are befet with leaves near a foot long, and almoft three inches broad in the middle. The flowers are of a cream colour: and are fucceeded by large oval fruit covered by a brownifli Ikin, inclofing a thick pulp of a ruffet colour, very lufcious, and called natural marmalade, from its refemblance to that of quinces. The ftdnes taken in emulfion are reckoned good againft the gravel.—Thefe trees being natives of very hot climates, cannot be pre- ferved in this country except in the warmeft ftoves. ACHROMATIC, an epithet exprefling want of colour. The word is Greek, being compounded of «, privative, and xPaf*a’ cel°ur' Achromatic Telefcopes, are telefcopes contrived to remedy the aberrations in colours ; fee Aberration. -—A particular account of the invention and conftruc- tion of thefe inftruments will be found under Optics. ACHTELING, a meafure for liquids ufed in Ger¬ many. Thirty-two achtelings make a heemer; four fciltims or fciltins, make an achteling. ACHYR, a ftrong town and caftle of the Ukrain, fubjeft to the Ruffians fince 1667. It Hands on the river Uorlklo near the frontiers of Ruffia, 127 miles W. of Kiow, Long. 36. o. Lat. 49. 32. ACHYRANTHES, in botany, a genus of the pen- tandria order, belonging to the monogynia clafs of plants, and affociating with the Mifcellanex, in the 54th Natural Order. The characters are : The calyx is a double peri- anthium; the exterior one confifting of three lan¬ ced acute leaves, which are perfiftent; the interior of five leaves, alfo perfiftent. No corolla: The neftarium is five-valved, furrounding the germen, bearded at the top, concave* and falling off. The Jlamina confift of five filaments the length of the corolla, the anther# are ovate and incumbent. The pijlillum has a top- (haped germen ; the ftylus is filiform, and the length of the ftamina ; the ftigma is villous, and divided into two fegments. The perianthium is a roundifh one- celled capfule, not gaping. The feed \s fingle and ob- long‘ Of this genus eight fpecies are enumerated ; but the charafter of the genus does not agree in them all. The fpecies are all natives of the Indies. Only one of them, the amaranthus, is commonly cultivated in botanical gardens, and that more for the fake of va- Acican- riety than beauty. It grows to the height of three tll®ra» feet, with oblong pointed leaves. The flowers come Acidity, out in long fpikes from the extremities of the branches, u—v—» and appear in July, the feeds ripening in September. Plants of this kind muft be reared in a hot-bed, and may be tranfplanted when they have acquired fufficient ftrength. if kept in pots, and (heltered during the winter in a warm green-houfe, they will live two or three years. ACICANTHERA, in botany, the trivial name“of a fpecies of Rhexia. ACICUL.dE, the fmall pikes or prickles of the hedge-hog, echinus-marinus, &c. ACIDALIUS (Valens) would, in all probability, have been one of the greateft critics in thefe latter ages, had he lived longer to perfect thofe talents which na¬ ture had given him. He was born at Witftock, in Brandenburg ; and having vifited feveral academies in Germany, Italy, and other countries, where he was greatly efteemed, he afterwards took up his refidencc at Breflaw, the metropolis of Silefia. Here he remain¬ ed a confiderable time, in expectation of fome employ¬ ment;. but nothing offering, he turned Roman-catho¬ lic, and was chofen reCtor of a fchool at Nieffa. It is related, that about four months after, as he was fol¬ lowing a proceffion of the hoft, he was feized with a fudden phrenzy; and being carried home, expired in a. very ftiort time. But Thuanus tells us, that his ex- ceffive application to ftudy was the occafion of his un¬ timely death ; and that his fitting up a-nights in compo- fing his Conjectures on Plautus, brought upon him a diftemper which carried him off in three days, on the 25th of May 1595, being juft turned of 28. He wrote a Commentary on Quintus Curtius; alfo, Notes on Ta¬ citus, on the TwelvePanegyrics; befides fpeeches, let¬ ters, and poems.

On the other hand, the ftrong acids of vitriol, nitre, and even fea-falt, are altogether cauftic, and cannot be tailed until they have been largely diluted with water. 2. With water they combine into a fluid, the fpecific gravity of which is not a medium betwixt the water and acid feparately taken. This holds good with the ftrong acids, which grow hot with water, and fhrink into lefs bulk by reafon of their emitting a quantity of the fire they contain : but whe¬ ther it alfo takes place in the weaker acids, has not yet been afcertained; though the probability is, that it will take place in them alfo. 3. With fpirit of wine, they acid princi¬ ple. a new theory, firft publifhed by M. Lavoifier, and lire- fier’s hypa- nuoufly maintained by the French chemifts, viz. That thefis that the acid principle is contained in the air ; and, accor¬ ding as it combines itfelf with different fubftances, forms acids of different denominations. This theory he confiders as eftablilhed by numerous indifputable experiments. Thefe cannot here be de¬ tailed ; but his conclufions from the whole are, That ^ “ dephlogijitcated air enters as a conftituent part intoBafsof de- the compofition of feveral acids, particularly the phof- phlogiftica- phoric, vitriolic, and nitrous ; that this pure and high- ly refpirable air is the cdnftitutive principle of acidity th^acid ^ common to all acids ; and that the difference by which principle, they are diftinguiftied from each other is produced by the union of one or more principles befides this air, fo as to conftitute the particular form under which each acid appears.” To dephlogifticated air in its ftate of fixity, therefore, he gives the title of the aci¬ difying or oxygenous principle ; and concludes farther unite into a very volatile and inflammable fubftance cal- from his experiments, 1. “ That, when combined with led ether. __ This alfo muft be underftood only of the ftrong mineral acids, or of the acetous when very much concentrated; for the acids of tartar, borax, arfenic, lapis ponderofus (tungfien), and molybdaena, do not produce any. 4.

The opinion of Mr Lavoifier concerning the com- in fuch a manner as to form compounds confiderably pofition of acids has in part been adopted by Mr Kir- „ permanent, and whofe ingredients cannot be feparated without fome difficulty. This is the moft univerfal and wan; who,in histreatifeonPhlogifton,publifhediniyfly, ni0I)S> informs us, that he is now of opinion “ that dephlogifti- diftinguifhing mark; and there is not any acid but what cated air becomes an effential conftituent part of acids. — c .1 acids (he adds) confift of two principles : one pe¬ culiar to each, which, in the opinion of the antiphlo- giftians, has not as yet been deCompofed, and confe- fhows its attraftion for one or other of thefe fubftances, efpecially the alkaline falls.

They cannot be frozen but in a degree of cold below the freezing point of water. This property is likewife not univerfal, but is remarkable only in the ftronger acids. a The nature of acids has long been a matter of fpe- Of the na- culat’on, and of late has engaged the attention ofphi- ture of acids, lofophers very confiderably. Some have fuppofed them acid bajis ; the laft, the oxygenous principle : thus the vitriolic acid, according to them, confifts of fulphur as its bafis, and pure air in a concrete ftate as its aci¬ difying or oxygenous principle. This doftrine of the compofition of acids has been admitted by fome of the ableft defenders of phlogifton, and particularly by that diftinguiftied philofophic chemift M. de Morveau, with this Angle modification, that the bafes of acids contain to be fim'ple chemical elements, while others imagined phlogifton, which they lofe on uniting to pure air: them to be compofed of water and earth. Both thefe opinions, however, are inadmiffible ; the former, becaufe we are certain that moft acids may be entirely decompofed, and refolved into aerial vapours of differ¬ ent kinds, which could not happen if they were fimple and unchangeable elements; the latter, becaufe there is not the finaHeft probability that two ingredients, feemingly fo infipid and inactive as water and earth, could by their union produce a compound endowed yet it feems very difficult to conceive how pure air can unite to phlogifton, a fubftance to which it has the greateft affinity, without forming a new compound endowed with very different properties from thofe which it poffeffed before fuch union. It feems therefore more reafonable to conclude, either that it forms water, as Mr Cavendifh thinks ; or fixed air, as I lhall afterwards endeavour to prove.” In his explanation of the formation of acids, Mr' Kirwan A C I [ 7* 1 A G I Kirwan firft ft ate s the opinion of the antiphlogiftians, gifticated air, phlogifticated air, and inflammable air, viz.That the vitriolic acid, when confidered abftraftedly all in their concrete ftate. ^ from the water it contains, always confifts of fnlphur “ Red, yellow, green, and blue nitrous acids, (which they conftder as a limple fubftance) united to a when thofe colours are intenfe, owe their origin to the large portion of the oxygenous principle. “ In my opi- abforption of nitrous air ; and confequently the pro- nion (fays he), it confifts of a bafts or radical principle, portion of their principles is variable, though all which, when faturated with phlogifton, conftitutes ful- have the dephlogifticated acid for their ground. Thus phur ; when faturated with fixed air, becomes common Dr Prieftley, having expofed ftrong pale-yellow nitrous fixed vitriolic acid; and, when combined partly with the one and partly with the other, becomes volatile vitri¬ olic acid. That fulphur, during its converfion into vi- acid, whofe fpecific gravity could not be lefs than 1.400 to nitrous air, found that 100 grains of this acid abforbed, in two days, 247 cubic inches of nitrous triolic acid, unites to air of fome fort or other, is evident air : now, 100 grains of this fpirit muft have contain- from the quantity of air which it abforbs, in whatever way that converfion is brought about. Thus, firft, du¬ ring combuftion in refpirable air, 100 grains of fulphur abforb 420 cubic inches of pure air, or about 143 grains: but the proportion of this pure air united with a given quantity of fulphur is not eafily determined, becaufe it is vitriolic air that is conftantly formed; and this air effentially contains fome portion of fulphur in folution, which portion is variable. Secondly, Pyrites, during their decompofition, abforb a confiderable proportion of pure air, as Mr Lavoifier has obferved; fo alfo does liver of fulphur expofed to the atmofphere, for after fome time it is converted into tartar vitriolate.” Mr Kirwan next proceeds to inquire, whether the air abforbed during the combuftion of fulphur continues b" to be pure air; or whether tPeburning or fixed ? He inclines to the latter opinions, for va- B of fulphur rious reafons * which he fpecifies. ed, by my calculation, about 21 grains of dry acid, and thefe 21 grains took up 91.39 grains of nitrous air. When about 20 cubic inches of nitrous air were abforbed (that is, about feven grains), the acid became of an orange colour ; when 50 cubic inches were ab¬ forbed (about 18 grains), it became green ; and when nearly the whole was abforbed, it evaporated in the form of nitrous vapour, carrying off part of the wa¬ ter with it. Hence we fee, that nitrous vapour con¬ fifts of nitrous acid united to three or four times its weight of nitrous air and a little water.” Mr Kirwan next proceeds to conteft Mr Lavoifier’s 9 opinion, that nitrous air is a conftituent principle of the ^Ir,L?'V01' nitrous acid. “ The following experiments (fays he) (-ontefted ^ fhow that nitrous air is not a conftituent principle of be converted into water the nitrous acid, but that fixed air is. 1.

But nitrous air, as Mr Lavoifier himfelf has obferved, is a compound ; 100 grains of it, according to him, containing 32 of phlogifticated and 68 of pure air ; confequently 64 grains of it contain 20.5' of phlogifticated air, and 43.5 of pure air. Hence, according to him, 100 grains of dry nitrous acid contain 794 of pure air and g 204- of phlogifticated air. Mr Kirwan is of opinion q Proportion t^iat 100 grains of pure, dry, and colourlefs nitrous ■iofitsconfti-acid contain 38.17 grains of fixed air as its acidifying jfctuent parts, principle, 57.06 of nitrous bafis, and 4.77 of phlogifton united to the nitrous bafis. With regard to the nitrous bafis itfelf, he fays that one third of its weight is phlogifticated and two thirds dephlogifticated air, both in a concrete ftate. dephlogifticated air more or lefs pure, the phlogifton of the fixed air being detained by the metal. Mr Ber- thollet, who feems to have made the experiment with the greateft exa&nefs, produced 714 cubic inches of de¬ phlogifticated air from a Troy ounce of nitre. This, however, was far from being of the pureft kind; and Dr Prieftley, Mr Berthollet, and Mr Succow, obfer¬ ved, that the air which firft paffes contains fixed air, and renders lime-water turbid. Here then we have three of the conftituent parts of the nitrous acid, with fcarce any nitrous air; which the antiphlogiftians fup- pofe to be one of the conftituent parts of the acid,, and to make two thirds of its bulk when exhibited in an aerial form.” To obviate an obje&ion that the quantity of fixed air thus obtained is too fmall to deferve to be ranked- among the conftituent. parts of the nitrous acid, Mr Kirwan firft inquires in what proportion it ought to “ Nitrous bafis (fays Mr Kirwan), faturated with exift there; and though this is variable, according to phlogifton, conftitutes nitrous air : 100 grains of this the different ftates of the nitrous acid with refpecl to bafis take up nearly 22 of phlogifton. lienee the con- phlogiftication, he reckons it at one-third of the acid ftituent principles of nitrous acid are fixed air, dephlo- as exifting in the nitre ; . and, from tlie decompofition of 3 thii A C I [ 72 1 A c r Acids, tin's fixed air, and the phlogifton emitted by it of confe- quence> he attributes the phlogiftication and rednefs of the nitrous acid when expofed to more heat. As a proof that fixed air may be decompofed in this man¬ ner, he adduces two experiments of Dr Prieftley. In one of thefe, dephlogifticated air was obtained by means of acetous acid in that concentrated ftate in which it is called radical vinegar. Having mixed half an ounce of the acid with two ounces of calcined whiting, he obtained from it 350 ounce-meafures of air; of which about one-third was fixed more in the firft: portions, and lefs in the laft. The ftandard of the refiduum in the firft portions was, 1.66, in the fecond, 1.42, and in the third, 1.38 ; which is very near the goodnefs of common air. The whiting then weighed 760 grains. On adding a quarter of an ounce more of radical vine¬ gar, and repeating the operation, 120 ounce-meafures of air were obtained, and the whiting was reduced to 73° grains* A third operation, in which another quar¬ ter of an ounce of vinegar was added, reduced the mat¬ ter to 489 grains ; but the laft portion of air extracted had no fixed air, arid was confiderably better than that of the atmofphere. The other experiment was made with lime-ftone alone; from four ounces of the white cryflahy of which 830 ounce-meafures of air were ob¬ tained, the firft portion of which had only one-fourth of fixed air, and the ftandard of the refiduum was ne¬ ver better than 1.56, nor worfe than 1.66 ; fo that it was nearly of the goodnefs of common air. Our author then proceeds to relate feveral other ex¬ periments in which the nitrous acid was decompofed; but a particular relation of them would fwell this ar¬ ticle beyond its due bounds. At laft, however, he concludes in the following manner. “ If fpirit of nitre be made to boil, and its vapour received through a red-hot earthen tube, it will be converted into de¬ phlogifticated air, in which a portion both of phlogi- fticated and fixed air is found, as Dr Prieftley has dif- covered : the water through which this air paffes will alfo contain fixed air. Here then are feveral ways of decompofing the nitrous acid ; and in one only it is refolved into nitrous and dephlogifticated air ; and in this way it may, at leaft, be ftrongly fufpedled to re¬ ceive an addition of another principle. Why then fhould 10 thefe be regarded as its conftituent principles ? And as Fixed air in the two fimpleft methods of decompofition, in which elements "of ^ rea&ion of no foreign fubftanee can be fufpe&ed, nitrousacid. ^ appears in the form of dephlogifticated, phlogiftica- ted, and fixed air (the former always containing a por¬ tion of the two laft), why then fhould not thefe be ac- 11 counted its true conftituent parts ? This theory How ni- is further confirmed by reflefting on the manner in trims acid is nitrous acid is generated by nature. Mr generated. Thouvenel found that this acid is conftantly produ¬ ced when chalk is expofed to a mixture of putrid air and common air, or putrid and dephlogifticated air; but if the putrid air be pafled through lime-water, it is never generated ; and that it is rarely produced by the expofure of quick-lime or fixed alkalis to thefe airs. The reafon that alkalis, though aerated, are not fo proper, is, that they do not combine with phlogiftica- ted air as calcareous earths do. Mr Cavendifh, indeed, produced nitrous acid without any apparent mixture of fixed air ; but the atom of it neceffary for the for¬ mation of the fmall quaptity of nitrous acid he produ- No. 2. 2 ced (about one-third of a grain), might well be con- Acids, tained in the phlogifticated air he employed, or perhaps v—^ formed in the operation.” Having thus far ftated the different opinions of the moft celebrated French and Englifh philofophers conceraing the compofition of acids, it is neceffary ra to take notice of fome experiments made by Mr^*^1^ Watt, in order to determine whether the dephlo-jyir Wat: gifticated air produced from nitre really proceeds from which a decompofition of the acid, or what quantity of the ('eem cnH" latter is required to conftitute a determinate ftuan‘Kirwan’* f tity of the former. To afcertain this*, 240 grains of do&nne. mercury were put into a glafs retort with 480 grains * Philof. of diluted dephlogifticated nitrous acid, which was the Tranf. quantity neceffary to diffolve the whole of the mercury; v‘ *x‘v' and as foon as the common air was expelled, a proper^’ ^ veffel was applied to receive the air produced in the operation. Sixteen ounce-meafures of nitrous air came over during the folution, and on changing the recei¬ ver, a quantity of dilute, but highly phlogifticated ni¬ trous acid, was obtained. The air receiver being again applied, four ounce meafures of ftrong and pure nitrous air were obtained, which, by the dephlogifticated air that arofe immediately after, were reduced to half an ounce meafure. The produ&ion of dephlogifticated air continued very rapid, the mercury being all the while received, until the operation was ended by the diftillation or fublimation of the whole of the mercury. Two hundred and eighteen grains of the metal were obtained in its running form, and 22 remained in the form of an orange-coloured fublimate in the upper part of the retort.—The 16 ounce-meafures of nitrous air, firft obtained, were then converted into nitrous acid by the gradual admiffion of common air, and then added to the water in the bafon in which the receiver had been inverted ; the whole quantity being about two quarts, and very acid to the tafte, fparkling at the fame time with nitrous air. To determine the quantity of acid thus recovered, as well as that which remained in the fublimate, a folution of alkali of tartar was made; and by experiment it was found, that 120 grains of the acid, originally employed in diffolving the mercury, fa- turated 352 grains of this folution ; the orange colour¬ ed fublimate and all the acid liquor recovered being fa- turated by 1395 grains of the fame. Hence it ap¬ pears, by the rule of proportion, that out of 480 grains of nitrous acid originally employed, only five were loft; “ a fmaller quantity (as Mr Watt juftly obferves) than what might reafonably be fuppofed to be loft in the procefs by the extreme volatility of the nitrous acid.” His conclufion therefore is, that “ the nitrous acid does not enter into the compofition of dephlogifticated air: it feems only to ferve to abforb phlogifton from the watery part of the mercurial nitre.” This experiment was repeated with cubic nitre, and only 30 ounce-meafures of air diftilled from an ounce of the mineral alkali exaftly faturated with nitrous acid. The water through which the air paffed was acid, and the refiduum in the retort alkaline; but on mixing the two together, the folution was found to be exactly neu¬ tral by every poflible teft. Not fatisfied with thefe experiments, Mr Watt di¬ ftilled an ounce (480 grains) of common nitre, Hop¬ ping the procefs when 50 ounce-meafures of air had been produced. This air had a ftrong fmell of the nitrous Anfwered by Mr Kir- wan.

K having A G I [ 74 1 A C I Acids, having pafled the fleam of boiling water through man- ganefe heated in an earthen tube, obtained a very large quantity of fused air, and fcarce any other ; though on repeating- this experiment with manganefe well freed from calcareous earth, I obtained a large portion of de- phlogifticated air ; but I believe much depends on the degree of heat to which the tube is fubjected. But having diftilled manganefe, which yielded of itfelf feme fixed air with common fpirit of fait, I obtained de- phlogifticated marine acid, and not a particle of fixed air ; which fhows that this laft combined with the de» phlogillicated bafis, and formed the dephlogifticated acid. Mr Hermftadt having diffolved the black calx in common marine acid, and precipitated it with an ae¬ rated fixed Alkali, obtained, as ufual,. a-white precipi¬ tate; which, when heated, afforded a great part of the fixed air it had abforbed from the alkali; but when heated to fuch a degree as to be of a brown red colour, and confequently dephlogifticated; it converted- com¬ mon fpirit of fait; into a dephlogifticated acid,which could proceed!; only-from, fome fixed air yet unexpelled : Yet if fal-ammoniac be diftilled with the black calx of man¬ ganefe, it will be expelled in a cauftic ftate ; 'for the fixed air unites to the dephlogifticated marine bails'in preference to the volatile alkali. jg Several other experiments are related by Mr Kirwan, Decifive ex-which the limits-, of this article will not allow us to in- periment in.fert. but the following,.he is of opinion, fully confirms his favour, pjg hypothefis, and fubverts that of the antiphlogiftians. “ Six.cubic inches .of inflammable air were mixed with as much dephlogifticated marine air over lime-water. In about 10 minutes after the greater part of the di¬ minution had taken place, a white cloud appeared on the furface [a) of the lime-water,, and by agitation it became ftill more turbid. As it was poffible that, the manganefe might be mixed with calcareous earth, fome dephlogifticated marine air was extracted from another portion of it, and received on lime-water ; but it was wholly abforbed, without forming the leaf! cloud, tho’ there was lime enough ; for, on adding aerated water, a cloud appeared.” jp The other acids particularly treated of fey Mr Kir- Phofphoric wan are the phofphorie and faccharine. In his treatife acid. on the former, he adopts the analyfis of Mr Lavoifter, changing only his acid principle of dephlogifticated for fixed air. From this it appears, that the phofpho- ric acid confifts of a peculiar bafis united to 2.265 its weight of the acid principle ; or, in other words, roo grains of dry phofphoric acid contains about 6g o{ fixed air and 31 of its peculiar bafis r too grains of the phofphoric bafis take up 226,5 hxed air, or 32.9 of phlogifton when it becomes phofpHorus ; and 100 grains of phofphorus contain 75.24 of bafis and 34.76 of phlogifton.—The bafis of this acid is the only one that can be procured free, both from the phlogi¬ fton and the acidifying principle ; it is called, though improperly, as it is not foluble in water, the glacial phofpboric acid., Mr Lavoifier and others are of opi¬ nion, that phofphorus is a Ample fubftance containing no phlogifton, and that the acid confifts of the oxyge¬ nous principle united to it. With regard to the acid of fugar, Mr Kirwan ob- Acids, ferves, that fugar itfelf is a compound of fixed air with ^ a much larger proportion of inflammable air, and fome s -.eclianae water, all condenfed to a degree of which we are ig-acid. norant, but retaining, upon the whole, much more fpe- eific heat than either oil or charcoal; though he feems inclined to the hypothefis of Mr Morveau, that this fubflance has for its bafis a fine ethereal oil, to which a-large proportion of condenfed inflammable-air is fu- peradded. The acid of fugar, then, according to him, confifts of this peculiar bafis deprived of its fuperfluous phlogifton, and united to a great quantity of fixed air in a concrete ftate. He is alfo of opinion, that it does not exift ready formed in the fugar, but is produced in the operations that fubftance undergoes: that it de¬ rives moft of its acid principle from the nitrous acid employed ; the nitrous bafts taking up the phlogifton, and the fixed air of the nitrous acid combining with the faccharine bafis. He contefts ftrongly an opinion of Mr Lavoifier, that fugar is a fort of charcoal, which, uniting with the oxygenous principle of the nitrous acid, decompofes it, fets loofe the nitrous air, and forms the faccharine acid ; and that, towards the end of the operation, the faccharine acid itfelf is decom- pofed; the confequence of which is the produc¬ tion of fixed air, which, according to'him, is only the oxygenous principle combined with charcoal. On this Mr Kirwan remarks, 1. “ That, according to this the¬ ory, the acid of fugar fliould be the fame with fixed air, fince both are compofed of the oxygenous prin¬ ciple united with charcoal: or, if Mr Lavoifier (hould reply, that fugar is different from common char¬ coal,. he reminds him, that, according to his own ta¬ ble of affinities, the oxygenous principle has a much ftronger attra&ion for charcoal than for fugar, and confequently that the latter ought to be decompofed by-the former; nay, that it ftiould be regenerated by various metallic fubftances, which, according to him,, have a greater attra&ion for this principle. 2. Accor¬ ding to this hypothefis, the faccharine acid ought to weigh more than the fugar employed in the operation; which is fo far from being the cafe, that it is univer- fally agreed to be much lefs; Bergman making it only •fd, Mr Chaptal from -fd to f-ths, and Mr Sage -f-^tha. 3. If the faccharine acid confifted of fugar, or confift- ed of that fubftance undecompofed, and barely united to the oxygenous principle, it ought to be formed by treating fugar with the black calx of manganefe, or with dephlogifticated marine acid ; both of which, ac¬ cording to him, have lefs attradlion for the oxygenous principle than'fugar. Laftly, (fays Mr Kirwan), If the . 2r, acid of fugar be diftilled, it is wholly converted into water, fixed inflammable air, and not a particle of coalpr;nc;pie>. or dephlogifticated air is found in it. It is; not there-according fore reafbnable to- look on either of them as its confti-t0 Kir“~ tuent principles; but as fixed air alone can be extrac- wan‘ ted from all vegetable acids, it feems to be the true a- cidifiable principle ” Having given a view of the prefent opinions re¬ lative to the original formation of acids,- it remains to treat a little more particularly of each of the different kinds.. (a) On mixing thefe, a denfe white cloud appears ; one half the, bulk of both difappears, and the refidimm ex¬ plodes like a mixture of inflammable and dephlogifticated air. A C I Acids, kinds. They are divided into three different claffes, ' ^ expreffive of their origin, viz. the Mineral, Vegetable, Acids howan^ Animal. The mineral acids are thofe of vitriol, divided. nitre, fea-falt, borax, amber, fluor, arfenic, tungften, molybdsena, &c. The vegetable are, thofe of vine¬ gar, tartar, fugar, benzoin, apples, citrons, lemons, tamarinds, forrel, cork, &c. The animal acids are, the microfmic or acid of urine, and that of bones, both of which are alfo called the phofphoric, though this might be accounted a vegetable acid, as it is procured by diHilling muftard and fome other vegetables by a violent fire. Befides thefe, there are the acids of ants, wafps, bees, filk-worms, milk, &c. It has alfo been difcovered, that the human calculus is formed for the moll part of a peculiar acid, which has received the name of lithidjic acid. Laftly, As • an acid dillinft from all thefe, we may now add fixed air, by fome cal¬ led the aerial, and by others the cretaceous acid ; the latter appellation it derives from creta, chalk, becaufe it is found in that fubltance in great quantity. See Aerology. The general properties of acids have already been e- CounT ofaC" numerated > molt remarkable of which is their attrac- thcirattrac- t;'on f°r alkaline falts, earths, and metals. Though this ions for al- is common to all, yet very confiderable differences are ob- talis, &c, ferved among them in this re{pe£l, and on thofe differences depend almoft all the phenomena of that part of Che¬ mistry which treats of falts. As thefe phenomena are particularly confidered under that article, we lhall here only in general take notice, that the three acids named the vitriolic, nitrous, and marine, are the llrong- ell of them all; that is, if any other acid be united to [ is 1 A C I attraction for phlogiilon; and unite with certain oily Acidulous and inflammable matter fo vehemently as to occafion great heat, and fometimes even violent and unextin-. ^ ~ . guifliable flame. This is particularly the cafe with the nitrous acid, or with a mixture of the two; and indeed the nitrous acid, though weaker than the vi¬ triolic, (hows itfelf in every inftance to be far more ac¬ tive, and to perform all its operations with vaftly great¬ er rapidity, than the other. All thefe particulars, how¬ ever, as they properly fall under the article Chemi¬ stry, are there explained at length : together with the origin and peculiar methods of preparing each of the acids, and the various ufes to which they may be ap¬ plied in arts and manufadtures.

The rule, however, is liable to certain exceptions and vari¬ ations, depending chiefly on the circumftances of heat or cold, moifture or drynefs, and particularly on the ftate of the marine acid with regard to its being in the form of an aqueous fluid or reduced to a dry vapour. ACILIUS GLABRIO (Marcus), conful in the year of Rome 562, -and 211 years before the Chriftian sera, diftinguilhed himfelf by his bravery and conduct in gaining a complete victory over Antiochus the Great, king of Syria, at the ftreights of Thermopylae in Theffaly, and on feveral other occafions. He built the Temple of Piety at Rome, in confequence of a vow he made before the above mentioned battle: and the In this laft cafe it feems ftronger than either the vi- reafon of his giving it that name is very remarkable, triolic or nitrous; and even when in an aqueous ftate. The ftory is mentioned by Pliny, Valerius Maximus, both the nitrous and marine acids, when added in great and others. See the article Piety. quantity, feem to opprefs and overwhelm the ftronger vitriolic acid, fo that they wall partly expel it from an alkaline fait. This does not depend on the mere quan¬ tity of acidity they poffefs': for the acetous acid may be concentrated to fuch a degree as to become ftronger in tliis refpect than fpirit of fait; yet it will always be in¬ ferior in point of real ftrength, when tried with an alkali in competition with the latter. The aerial acid is the weakeft of all; and may be expelled not only by vine¬ gar, but by the acid juices of fruits, tartar, and the acids of tungften and molybdsena. Some acids have the property of refilling the .fire, and melting into a kind of glafs, fuch as that of borax and phofphorus.

No corolla. The jlaviina confift of five very ftiort capillary filaments j the anthers are verfa- tile, two-celled, and forked at both ends.—Female on a feparate plant of which the calyx confifts of an in- volucrum many-leav’d, linear, and deciduous; and a perianthium two-leaved, very fmall, and perfillent. No corolla. The pijlillum has an ovate germen ; the ftyli are five, long, reflected, and downy; the ftigmata are fimple. The pericarphwi is an egg-ffiaped fruit, com- prcffed, many-angled, fulcated, and covered with a fiicculent calyx. The feed is folitary, round, and com- preffed. There is only one fpecies of it, viz. the ae- nida cannabina. It is a native of Virginia; but rarely cultivated in Europe, except for the fake of variety. It has little beauty, and at prefent is applied to no ufeful purpofe. ACNUA, in Roman antiquity, fignified a certain mcafure of Lnd, near about the Englifh rood, or fourth part of an acre.

Acoluthi, among the ancient Chriftians, implied a peculiar 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 fub-deacon ; and we learn from the fourth council of Carthage, that the archdeacon, at their ordination, put into their hands a candleftick with a taper, giving them thereby to under- ftand that they were appointed to light the candles of the church; as alfo an empty pitcher, to imply that they were to furniffi wine for the eucharift.

ACONITUM, Aconite, Wolfsbane, or Monks¬ hood ; a genus of the trigynia order, belonging to the polyandria clafs of plants. In the natural order, it affociates with the Multifiliqux, 26. The cha- ratters are : There is no calyx. The corolla confifts of five unequal petals oppofite in pairs; the higheft hel¬ met-tubed, inverted, and obtufe ; the two lateral ones, broad, roundilh, oppofite, and converging; the two loweft, oblong, and looking downwards: The nedfaria are two, piped, nodding, and fitting on long fubulated peduncles, and concealed under the higheft petal: The fcales are fix, very (hort, coloured, and in an orb with the nedtaria. The Jlamina confift of numerous fmall fubulated filaments ; the antherae are eredl and fmall. Thepijlillum has three [five] oblong germens, ending in ftyli the length of the ftamina ; the ftigmata are fimple and refledled. The pericarplum has three or five uni¬ valve capfules gaping inward. The feeds are numerous, angular, and wrinkled. Species, f. The lycodlonum, or yellow wolfsbane, grows upwards of three feet high, flowers about the middle of June, and if the feafon is not warm will con¬ tinue in flower till Auguft. 2. The altifiimum, or greateft yellow wolfsbane, grows upwards of four feet high, and the fpikes of its flower are much longer in this fort than the former. 3. The variegatum, or leffer wolfsbane, feldora grows more than two feet high ; it carries blue flowers, and the fpikes of them are much fllorter than either of the two laft. 4. The anthora, or wholefome wolfsbane, flowers in the middle of Auguft, and often continues in beauty till the middle of September; its flowers are not large, but are of a beautiful fulphur-yellow colour. 5;. The napellus, bears large blue flowers, which appear in Auguft, and make a pretty appearance. There are two or three varieties of this kind ; one with white, another with rofe-co- loured, and a third with variegated flowers ; but thefe are only varieties which often change. 6. The pyra- midale, or common blue monklhood, bears a long fpike of blue flowers, which appear fooner than any of the other forts, being fo early as June, or fometimes even May. The fpikes of flowers are upwards of two feet long, fo that it makes a pretty appearance ; the feeds are ripe in September. 7. The alpinum, or large* flowered monklhood, flowers in Auguft, and will grow to the height of five feet in good ground ; the flowers are very large, of a deep blue colour, but not many upon each fpike. 8, The pyreniacum, or Pyrenean mcnklhood, flowers in July. It grows about four feet high, and carries a long fpike of yellow flowers. 9. The eammarum, grows about four feet high, and flowers in the beginning of July. 1 o. The orientale, or eaftern monkfhood, grows fometimes more thUn fix feet high, and bears a white flower. Culture.

They may all be propagated by lowing their feeds in ' ’Y autumn, upon a north border, where they are fereened from the fun. The plants will come up in the fpring, when they mint be kept clean from weeds during the fummer-months ; and, in very dry feafons, if they are frequently refrelhed with water, their growth will be greatly promoted. The following autumn they fhould be tranfplanted into ftlady borders, in rows a foot afun- der, and the plants fix inches diftant from one another. In this fituation they may remain two years, when they will carry flowers, and fo may be tranfplanted to thofe places where they are to remain. The eaftern monks¬ hood is a native of the Levant, from whence the feeds of it were firft fent by Dr Tournefort to the royal gar¬ den at Paris, from whence fome other gardens have been furniihed with feeds. It is very rare in Europe at pre- fent. Qualities. Since the time of Theophraftus, moft of the fpecies of monkfhood have been reckoned a deadly poifon both to men and brutes. Diofcorides, however, recommends the external application of common monks¬ hood for pains of the eyes. The flowers of a great many fpecies communicate their noxious quality by being fmelled to ; and thofe of the fpecies called na¬ pellus being placed on the head, occafion a violent me¬ grim. Of the bad" qualities of thefe plants we fome¬ times avail ourfelves to get rid of vermin. A decoc¬ tion of the roots deftroyed bugs ; the fame part being powdered, and adminiftered in bread or fome other pa¬ latable vehicle to rats and mice, corrodes and inflames their inteftines, and foon proves mortal. The juice of the plant is ufed to poifon flefh with, for the deftruc- tion of wolves, foxes, and other ravenous beafts. The beft antidote to the poifon of the different monks¬ hoods is faid to be the root of the anthora, a fpecies of the fame genus, hence termed healthful or ivholefome monkjhood. The fame plant is regarded as efficacious againft bites of ferpents and other venomous creatures. The roots have a bitter acrid tafte ; the leaves are only bitter : the former are chiefly ufed in medicine ; and, befides the Excellent quality juft mentioned, are fto- machic, and promote perfpiration. The peafants, who gather the plants on the Alps and Pyrenees, are laid to ufe it with fuccefs againft the biting of mad dogs, and ■ to cure the colic. It is remarkable, that the monks¬ hoods with blue flowers are much more virulent than the yellow or white-flowered kinds. Miller afferts that the huntfmen of the wolves and other wild beafts on the Alps, dip their arrows into the juice of thofe plants, which renders the wounds made by them deadly. That the anthora is an antidote to the poifon of the reft of the fpecies, is not confidered as a fail fufficient- ly eftabliftied. Of the effedls of the above, indeed, and other vegetable poifons, medical writers give but a confufed account. In general, thofe which are not of the narcotic kind, nor excite violent vomitings and purgings, produce their pernicious effefts by irritating the nervous coats of the ftomach and inteftines, fo as to occafion violent convulfions, not- only in them, but through the whole body. The proper cure is evacua¬ tion by vomit: but this is not to be obtained without fome difficulty ; becaufe there is ufually fuch a contrac-* tion about the upper orifice of the ftomach,, that no¬ thing • Acoms AGO [ 78 ] AGO Acer.tia? thing can either be fwallowed or thrown up. In this terminating in a point; the root is pretty long, o£ a cafe,~ an infufion of tobacco has been recommended, j and may probably be of fervice : for being itfelf of a whitifh, reddiih, and partly greenifh colour.

On account of the poifonous qualities of monkftiood, no fpecies of it fhould be plant¬ ed where children have accefs, left they fttould fuffer by putting the leaves or flowers in their mouths, or rubbing them about their eyes; for the juice of the kaves will occafion great diforder by being only rubbed upon very tender flefti; and the farina of the flowers, when blown into the eyes, caufes them to fwell greatly. ACONT-IAS, in zoology, an obfolete name of the paler green. On this grow frequently two fpikes of flowers, by many writers called juli. Thefe are of a brown colour, having a chequered furface. The root of this plant has a very agreeable flavour, which is greatly improved by drying. It is reckoned carmina-: tivc and ftomachic, having a warm, pungent, bitterifh tafte 5 fo is frequently ufed as an ingredient in bitters. It has been complained of, however, as communicating a naufeous flavour to thofe bitters in which it was in- fufed ; and Neumann obferves, that its agreeable fla¬ vour, as well as its diftinguiftiing tafte, refide entirely in a volatile effential oil; the refiduum after diftillation having a naufeous flavour, not at all refembling that of anguis jaculis, or dart-fnake, belonging to the order the calamus.

Chap. I. Different Theories of Sound. 3 , Moll founds, we all know, are conveyed to us on c’esof fbund t^le bofopi of the air. In whatever manner they either float upon it, or are propelled forward in it, certain it is, that, without the vehicle of this or fome other fluid, we fliould have no founds at all. Let the air be ex- haufted from a receiver, and a bell fliall emit no found when rung in the void ; for, as the air continues to grow lefs denfe, the found dies away in proportion, fo that at laft its ftrongeft vibrations are almoft totally filent. 4 Thus air is a vehicle for found. However, we mall Air nut the not, with fome philofophers, affert, that it is the only only one. vehicle ; that, if there were no air, we fliould have no founds whatfoever: for it is found by trial, that founds are conveyed through water almoft with the fame faci¬ lity with which they move through air. A bell rung in water returns a tone as diftinft as if rung in air. This was obferved by Derham, who alfo remarked that the tone came a quarter deeper. Some naturalifts affure us alfo, that fillies have a ftrong perception of founds, even at the bottom of deep rivers (a). From hence, it would feem not to be very material in the propaga¬ tion of founds, whether the fluid which conveys them be elaftic or otherwife. Water, which, of all fubftan- ees that we know, has the leaft elafticity, yet ferves to carry them forward; and if we make allowance for the difference of its denfity, perhaps the founds move in it with a proportional rapidity to what they are found to do in the elaftic fluid of air. One thing however is certain, that whether the fluid which conveys the note be elaftic or non-elaftic, what¬ ever found we hear is produced by a ftroke, which the founding body makes againft the fluid, whether air or water. The fluid being ftruck upon, carries the im- preflion forward to the ear, and there produces its fen- fation. Philofophers are fo far agreed, that they all 5 allow that found is nothing more than the impreffion's made by an elaftic body upon the air or water (b), and propagated.' this impreflion carried along by either fluid to the or¬ gan of hearing. But the manner in which this convey¬ ance is made, is ftill difputed : Whether the found is diffufed into the air, in circle beyond circle, like the waves of. water when we difturb the fmoothnefs of its furface by dropping in a ftone; or whether it travels along, like rays diffufed from a centre, fomewhat in the fwift manner that ele&ricity runs along a rod of ron; thefe are the queftions which have divided the learned. Newton was of the firft opinion. He has explained 5 the progreflion of found by an undidatory, or rather a Newton'* vermicular, motion in the parts of the air. If we have theory, an exadt idea of the crawling of fome infedts, we fliall have a tolerable notion of the progreffion of found upon this hypothefis. The infeft, for inftance, in its motion, firft carries its contractions from the hinder part, in or¬ der to throw its fore-part to the proper diftance, then it carries its contractions from the fore-part to the hin¬ der to bring that forward. Something fimilar to this . (a) Dr Hunter has proved this, and demonftrated the auricular organ in thefe animals. See Fish, and Compa¬ rative Anatomy. (b! Though air and water are both vehicles of found, yet neither of them feems to be fo by itfelf, but only as it contains an exceedingly fubtile fluid capable of penetrating the moft folid bodies. Hence, by the medium of that fluid, founds can be propagated through wood, or metals, even more readily than through the open air. By the fame means, deaf people may be made fenfible of founds, if they hold a piece of metal in their mouth, one end of which is applied to the founding body. As it is certain, therefore, that air cannot penetrate metals, we muft ac¬ knowledge the medium of found to be of a more fubtile nature ; and thus the electrical fluid will naturally occur as the proper one. But why then is found no longer heard in an exhaufted receiver, if the air is not the fluid by whicfi it is conveyed, feeing the eledtrical matter cannot be excluded ? The reply to this is obvious: The electrical fluid is 1 fo exceedingly fubtile, and pervades folid bodies with fo much eafe, that any motion of a folid body in a quantity of eleCtric matter by itfelf, can never excite a degree of agitation in it fufficient for producing a found ; but if the elec¬ tric fluid is entangled among the particles of air, water, wood, metal, &c. whatever affedts their particles Will alfo af- fedt this fluid, and produce an audible noife. In the experiment of the air-pump, however, there may be an ambi¬ guity, as the gradual exhaufting of the air creates an increafmg difference of preffure on the outfide, and may occa- !' fion in the glafs a difficulty of vibrating, fo as to render it lefs fit to communicate to the air without the vibrations that ftrike it from within. From this caufe the diminution of found in an exhaufted receiver may be fuppofed ter proceed, as well as from the diminution of the air. But if any internal agitation of its parts fhould happen to the eledtrical fluid, exceeding loud noifes might be propagated through it, as has been the cafe when large meteors have H ' kindled at a great diftance from the earth. It is alfo difficult to account for the exceeding great fwiftnefs of found, upon the fuppofition that it is propagated by means of air alone; for nothing is more certain, than that the ftrongeft' and mofi.violent gale is, in its courfe, inert and fluggifh, compared with the motion of found. l ■So ACOUSTICS. Ch.T Different is the motion of the air when ftruck upon by a founding ^'Sound ofbody* d-'° be a httle more precife, fuppofe ABC, the ■ ° ^ ' j ftring of an liarpfichord ferewed to a proper pitch, and Plate I. drawn out of the right line by the finger at B. We fig-1- (hall have occafion elfewhere to obferve, that fuch a firing would, if let go, vibrate to E; and from E toD, and back again ; that it would continue thus to vibrate like a pendulum for ever, if not externally refifted, and, like a pendulum, all its little vibrations would be per¬ formed in equal times, the laft and the firft being e- cpially long in performing ; alfo, that, like a pendulum, its greateft fwiftnefs would always be when it arrived at E, the middle part of its motion. Now then, if this ftring be fuppofed to fly from the finger at B, it is ob¬ vious, that whatever be its own motion, fuch alfo will be the motion of the parts of air that fly before it. Its motion, as is obvious, is firft uniformly accelerated for¬ ward from B to E, then retarded as it goes from E to ID, accelerated back again as it returns from D to E, ^ and retarded from E to B. This motion being there¬ fore fent in fucceffion through a range of elaftic air, it muft happen, that the parts of one range of air muft be fent forward with accelerated motion, and then with a retarded motion. This accelerated motion reaching the remoteft end of the firft range will be communi¬ cated to a fecond range, while the neareft parts of the firft range being retarded in their motion, and falling back p ith the receffion of the ftring, retire firft with an accelerated, then with a retarded motion, and the remoteft parts will foon follow. I n the mean time, while the parts of the firft range are thus falling back, the parts of the fecond range are going forward with an accelerated motion. Thus there will be an alter¬ nate condenfation and relaxation of the air, during the time of one vibration ; and as the air going forward ftrikes any oppofing body with greater force than upon retiring, fo each of thefe accelerated progreffions have been called by Newton a pulfs of found. Thus will the air be driven fonvard in the dire&ion of the ftring. But now we muft obferve, that thefe pulfes will move every way ; for all motion imprefled upon fluids in any direction whatfoever, operates all around in a fphere : fo that founds will be driven in all directions, backwards, forwards, upwards, downwards, and on every' fide. They will go on fucceeding each other, one on the outfide of the other, like circles in difturbed water; or rather, they will lie one without the other, in concentric fhells, fhell above fiiell, as we Tee in the coats of an onion. All who have remarked the tone of a bell, while its founds are decaying away, muft have an idea of the pulfes of fpund, which, according to Newton, are form¬ ed by the air’s alternate progreflion and recefiion. And it muft be obferved, that as each of thefe pulles is formed by a Angle vibration of the ftring, they muft be equal to each other; for the vibrations of the ftring are known to be fo. Again, as to the velocity' with which founds travel, this Newton determines, by the moft difficult calcuht* tion that can be imagined, to be in proportion to the thicknefs of the parts of the air, and the diftance of thefe parts from each other. From hence he goes on to prove, that each little part moves backward and for- ward like a pendulum ; and from thence he proceeds to demonftrate, that if the atmofphere were of the fame No. 2. 3 denfity every where as at the furface of the earth, in Different fuch a cafe, a pendulum, that reached from its higheft^^^*^ furface down to the furface of the earth, would by its . ^ ' . vibrations difeover to us the proportion of the velocity with which founds travel. The velocity with which each pulfe would move, he (hows, would be as much greater than the velocity of fuch a pendulum fwinging with one complete vibration, as the circumference of a circle is greater than the diameter. From hence he calculates, that the motion of found will be 979 feet in one fecond. But this not being confonant to ex¬ perience, he takes in another confideration, which de- ftroys entirely the rigour of his former demonftration, namely, vapours in the air j and then finds the motion of found to be 1142 feet in one fecond, or near 13 miles in a minute : a proportion which experience had efta- blifhed nearly before. Thus much will ferve to give an obfeure idea of ap theory which has met with numbers of oppofers. Even ’Theory^ John Bernouilli, Newton’s greateft difciple, hiodeftly pofed. owns that he did not pretend to underftand this part of the Principia. He attempted therefore to give a more perfpicuous demonftration of his own, that might confirm and illuftrate the Newtonian theory. The fubjeft feemed to rejeft elucidation : his theory is ob- vioufly wrong, as D’Alembert has proved In his The¬ ory of Fluids. Various have been the objections that have been ^ _ made to the Newtonian fyftem of founds. It is urged, ™es*Jec that this theory can only 'agree with the motion of found in an elaftic fluid, whereas founds are known to move forward through water that is not elaftic. To explain their progrefs therefore through water, a fe¬ cond theory muft be formed : fo that two theories muft be made to explain a fimilar effect; which is contrary- to the fimplicity of true philofophy, for it is contrary to the firaplicity of nature. It is farther urged, that this flow vermicular motion but ill reprefents the velo¬ city with which founds travel, as we know by experi¬ ence that it is almoft 13 miles in a minute. In (hort, it is urged, that ftich undulations as have been deferi- bed, when coming from feveral fonorous bodies at once, would crofs, obliruft, and confound each other ; fo that, if they were convey-ed to the ear by- this means, we fhould hear nothing but a medley of difeord and broken articulations. But this is equally with the reft contradictory- to experience, fince we hear the fulleft concert, not only without eonfufion, but with the high- eft pleafure. Thefe objections, whether well founded or not, have given rife to another theory-: which we fnall likewife lay before the reader ; though it too ap¬ pears liable to objections, which fliall be afterwards mentioned. Every' found may be ccnfidered as driven off from 9 the founding body in ftraight lines, and impreffed upon Another the air hr one direction only-: but whatever impreffion Theory, is made upon a fluid in one direction, is diffufed upon its furface into all directions ; fo that the foundftirit driven diredtly forward fcon fills up a wide- fphere, and is heard on every fide. Thus, as it is imprefled, it in- ftantaneoufly travels forward w ith a very fwift motion, refembling the velocity- w-ith which w-e know- electricity flies from one end of a line to another.' Now, as to the pulfes, or clofe ihakes as the mufi- cians exprefs it, which a founding body- is known to - make Ch.L A C O U ! Cifferent make, each pulfe (fay the fupporters of this theory) |Theories of ^ a diftinif and perfect found, and the interval . aun('' , between every two pulfes is profoundly filent. Con- 1 tinuity of found from the fame body is only a decep¬ tion of the hearing ; for as each diftinA found fucceeds at very fmall intervals, the organ has no time to tranf- mit its images with equal fwiftnefs to the mind, and the interval is thus loft to fenfe: juft as in feeing a flaming torch, if flared round in a circle, it appears as a ring of fire. In this manner a beaten drum, at fome fmall diftance, prefents us with the idea of" con¬ tinuing found. When children run with their fticks along a rail, a continuing found is thus reprefented, though it need fcarce be obferved that the ftroke a- gainft each rail is perfectly diftindl and infulated. According to this theory, therefore, the pulfes are nothing more than diftindt founds repeated by the fame body, the firft ftroke or vibration being ever the loud- eft, and travelling farther than thofe that follow; while each fucceeding vibration gives a new found, but with diminifhed force, till at laft the pulfes decay away to¬ tally, as the force decays that gives them exiftence. All bodies whatfoever that are ftruck return more or lefs a found: but fome, wanting elafticity, give back no repetition of the found ; the noife is at once begot¬ ten and dies: while other bodies, however, there are, which being more elaftic and capable of vibration, give back a found, and repeat the fame feveral times fuc- ceffively. Thefe laft are faid to have a tone 5 the others are not allowed to have any. This tone of the elaftic fixing, or bell, is notwith- ftanding nothing more than a fimilar found of what the former bodies produced, but with the difference of being many times repeated while their note is but Angle. So that, if we would give the former bodies a tone, it will be neceffary to make them repeat their found, by repeating our blows fwiftly upon them. This will ef- fecftually give them a tone ; and even an unmufical in- ftrument has often had a fine effect by its tone in our concerts. Let us now go on then to fuppofe, that by fwift and equably continued ftrokes we give any non-elaftic body its tone: it is very obvious, that no alterations will be made in this tone by the quicknefs of the ftrokes, though repeated ever fo faft. Thefe will only render the tone more equal and continuous, but make no al¬ teration in the tone it gives. On the contrary, if we make an alteration in the force of each blow, a diffe¬ rent tone will then undoubtedly be excited. The dif- ference will be fmall, it muft be confeffed; for the tones of thefe inflexible bodies are capable but of fmall va¬ riation ; however, there will certainly be a difference. The table on which we write, for iaftance, will return a different found when ftruck with a club, from what it did when ftruck only with a fwitch. Thus non-elaftic bodies return a difference of tone, not in proportion to the fwiftnefs with which their found is repeated, but in proportion to the greatnefs of the blow which pro¬ duced it; for in two equal non-elaftic bodies, that body produced the deepeft tone which was ftruck by the great- eft blow’. We now then come to a critical queftion, What is it that produces the difference of tone in two elaftic founding bells or firings ? Or what makes one deep and the other fhrill ? This queftion has always been hitherto Vol. I. Part I. I T I C S. 81 anfwered by faying, that the depth or height of the Different note proceeded from the flownefs or fwiftnefs of the Theories of times of the vibrations. The flovveft vibrations, it has , Soua°s-^ been faid, are qualified for producing the deepeft tones, v while the fwifteft vibrations produce the higheft tones. In this cafe, an effeft has been given for a caufe. It is in faft the force with which the founding ftring ftrikes the air when ftruck upon, that makes the true diftinc- tion in the tones of founds. It is this force, with great¬ er or lefs impreffions, refembling the greater or lefs force of the blows upon a non-elaftic body, which produces correfpondent affeftions of found. The greateft forces produce the deepeft founds: the high notes are the ef- feft of fmall efforts. In the fame manner a bell, wide at the mouth, gives a grave found ; but if it be very maffy withal, that wall render it ftill graver; but if maffy, wide, and long or high, that will make the tone deepeft of all. Thus, then, udll elaftic bodies give the deepeft found, in proportion to the force wdth wjiich they ftrike the air : but if we ftiould attempt to increafe their force by giving them a ftronger blow, this will be in vain ; they will ftill return the fame tone; for fuch is their forma¬ tion, that they are fonorous only becaufe they are ela¬ ftic, and the force of this elafticity is not increafed by our ftrength, as the greatnefs of a pendulum’s vibra¬ tion will not be increafed by falling from a greater height. Thus far off the length of chords. Now as to the fre¬ quency with which they vibrate the deepeft tones, it has been found, from the nature of elaftic fixings, that the longeft firings have the wideft vibrations, and con- fequently go backward and forward floweft ; while, on the contrary, the Ihorteft firings vibrate the quickeft, or come and go in the fhorteft intervals. From hence thofe who have treated of founds, have afferted, as was faid before, that the tone of the ftring depended upon the length or the Ihortnefs of the vibrations. This, however, is not the cafe. One and the fame ftring, when ftruck, muft always, like the fame pendulum, re¬ turn precifely fimilar vibrations; but it is well known, that one and the fame ftring, when ftruck upon, does not always return precifely the fame tone : fo that in this cafe the vibrations follow one rule, and the tone another. The vibrations muft be invariably the fame in the fame ftring, which does not return the fame tone invariably, as is well known to muficians in general. In the violin, for inftance, they can eafily alter the tone of the firing an o&ave or eight notes higher, by a fofter method of drawing the bow ; and fome are known thus to bring out the moft charming airs imaginable. Thefc peculiar tones are by the Englifti fiddlers called flute- notes. The only reafon, it has been alleged, that can be affigned for the fame ftring thus returning different tones, muft certainly be the different force of its ftrokes upon the air. In one cafe, it has double the tone of the other; becaufe upon the foft touches of the bow, only half its elafticity is put into vibration. This being underftood (continue the authors of this theory), we {hall be able clearly to account for many things relating to founds that have hitherto been inexplicable. Thus, for inftance, if it be aflc- ed, When two firings are ftretched together of equal lengths, tenfions, and thicknefs, how does it happen, that one of them being ftruck, and made to vibrate L throughout, 82 ACOUSTICS. Ch.I Different throughout, the other fliall vibrate throughout alfo ? °^the anfwer is obvious: The force that the firing ftruck . ^ , receives is communicated to the air, and the air com¬ municates the fame to the fimilar firing; which there¬ fore receives all the force of the former; and the force being equal, the vibrations mufl be fo too. Again, put the queflion. If one firing be but half the length of the other, and be flruck, how will the vibrations be ? The anfwer is. The longefl firing will receive all the force of the firing half as long as itfelf, and there¬ fore it will vibrate in proportion, that is, through half its length. In the fame manner, if the longefl firing were three times as long as the other, it would only vibrate in a third of its length ; or if four times, in a fourth of its length. In fhort, whatever force the fmaller firing impreffes upon the air, the air will im- prefs a fimilar force upon the longer firing, and par¬ tially excite its vibrations. *0 From hence alfo we may account for the caufe of See1 Kat^l' thofe charming, melancholy gradations of found in the fig. 2. ' Eolian lyre ; an inflrument (fays Sir John Hawkins) lately obtruded upon the public as a new invention, * Vide Kir- though defcribed above a century ago by Kircher *. cheri Mu- This inflrument is eafily made, being nothing more Jjrgia, than a long narrow box of thin dale, about 30 inches long, 5 inches broad, and t-% inches deep, with a cir¬ cle in the middle of the upper fide or belly about 1J inch diameter, pierced with fmall holes. On this fide are feven, ten, or (according to Kircher) fifteen or more firings of very fine gut, flretched over bridges at each end, like the bridge of a fiddle, and fcrewed up or re¬ laxed with fcrew-pins (b). The firings are all tuned to one and the fame note ; and the inftrument is placed in fome current of air, where the wind can brufhr over its firings with freedom. A window with the fafh juft raifed to give the air admiffion, will anfwer this purpofe exaftly. Now when the entering air blows upon thefe firings with different degrees of force, there will be excited different tones of found; fometimes the blafl brings out all the tones in full concert; fometimes it finks them to the foftefl murmurs; it feels for every tone, and by its gradations of ftrength folicits thofe gradations of found which art has taken different me¬ thods to produce. It remains, in the lafl place, to confider (by this theory) the loudnefs and lownefs, or, as the muficians fpeak, the flrength and foftnefs of found. In vibra¬ ting elaflic firings, the loudnefs of the tone is in pro¬ portion to the deepnefs of the note; that is, in two firings, all things in other circumflances alike, the deepefl tone will be loudefl. In mufical inflruments upon a different principle, as in the violin, it is other- wife ; the tones are made in fuch inflmments, by a number of fmall vibrations crowded into one flroke. The rofined bow, for inflance, being drawn along a firing, its roughneffes catch the firing at very fmall intervals, and excite its vibrations. In this inflrument, therefore, to excite loud tones,- the bow muff be drawn quick, and this will produce the greatefl number of vi¬ brations. But it mull be obferved, that the more quick the bow paffes over the firing, the lefs apt will the roughnefs of its furface be to touch the firing at Different every inflant; to remedy this, therefore, the bow mufl be preffed the harder as it is drawn quicker, and thus. ou^n ' ■ its fullefl found will be brought from the inflrument. If the fwiftnefs of the vibrations in an inflrument thus rubbed upon, exceed the force of the deeper found in another, then the fwift vibrations will be heard at a greater diflance, and as much farther off as the fwiftnefs in them exceeds the force in the other. It By the fame theory (it is alleged) may all the phe-The nature nomena of mufical founds be eafily explained.—The fa- °f Mufical bles of the ancients pretend, that mufic was firfl found } d* out by the beating of different hammers upon the fmith’s anvil. Without purfuing the fable, let us en- the "fame -< deavour to explain the nature of mufical founds by a theory, fimilar method. Let us fuppofe an anvil, or feveral fi¬ milar anvils, to be flruck upon by feveral hammers of different weights or forces. The hammer, which is double that of another, upon linking the anvil will pro¬ duce a found double that of the other : this double found muficians have agreed to call an Odtave. The ear can judge of the difference or refemblance of thefe founds with great eafe, the numbers being as one and two, and therefore very readily compared. Suppofe that an hammer, three times Id’s than the firfl, flrikes the anvil, the found produced by this will be three times lefs than the firfl: fo that the ear, in judging the fimilitude of thefe founds, will find fomewhat more difficulty ; becaufe it is not fo eafy to tell how often one is contained in three, as it is to tell how often it is contained in two. Again, fuppofe that an hammer four times lefs than the firfl llrikes the anvil, the ear will find greater difficulty Hill in judging precifely the difference of the founds; for the difference of the num¬ bers four and one cannot fo foon be determined with precifion as three and one. If the hammer be five times lefs, the difficulty of judging will be flill greater. If the hammer be fix times lefs, the difficulty flill in- creafes, and fo alfo of the feventh, infomuch that the ear cannot always readily and at once determine the precife gradation. Now, of all comparifons, thofe which the mind makes moll eafily, and with leafl la¬ bour, are the mofl pleafing. There is a certain re¬ gularity in the human foul, by which it finds happi- nefs in exa6t and flrieking, and eafily-made comparr- fons. As the ear is but an inflrument of the mind, it is therefore mofl pleafed with the combination of any two founds, the differences of which it can mofl rea¬ dily diflinguifh. It is more pleafed with the concord of two founds which are to each other as one and two, than of two founds which are as one and three, or one and four, or one and five, or one and fix or feven. Up¬ on this pleafure, which the mind takes in comparifon, all harmony depends. The variety of founds is infi¬ nite ; but becaufe the ear cannot compare two founds fo as readily to diflinguifh their diferiminations when they exceed the proportion-of one and feven, muficians have been content to confine all harmony within that compafs, and allowed but feven notes in mufical com- pofition. Let us now then fuppofe a flringed inflrument fitted UP (b) The figure reprefents the inflrument with ten chords ; of which fome dirtil only eight to be tuned unifons, and the two Outernaoft odtaves below them. But this feems not to be material. ICh.I. A C O U Of Muficalup in the order mentioned above. For inftance : Let Sounds. t}ie ftnng be twice as long as the fecond ; let the third ftring be three times ihorter than the firft; let the fourth be four times, the fifth ftring five times, and the fixth fix times as ftiort as the firft. Such an in- ftrument would probably give us a reprefentation of the lyre as it came firft from the hand of the inven¬ tor. This inftrument will give us all the feven notes Following each other, in the order in which any two of them will accord together moft pleafingly ; but yet it will be a very inconvenient and a very difagreeable inftrument: inconvenient, for in a compafs of feven firings only, the firft muft be feven times as long as the laft ; and difagreeable, becaufe this firft ftring will be feven times as loud alfo ; fo that when the tones are to be played in a different order, loud and foft founds would be intermixed with moft difgufting alternations. In order to improve the firft inftrument, therefore, fucceeding muficians very judicioufly threw in all the other firings between the two firft, or, in other words, between the two Oftaves, giving to each, however, the fame proportion to what it would have had in the firft natural inftrument. This made the inftrument more portable, and the founds more even and pleafing. They therefore difpofed the founds between the Ocftave in their natural order, and gave each its own proportional di- menfions. Of thefe founds, where the proportion be¬ tween any two of them is moft obvious, the concord between them will be moft pleafing. Thus Octaves, which are as two to one, have a moft harmonious effect; the fourth and fifth alfo found fweetly together, and they wil^ be found, upon calculation, to bear the fame proportion to each other that Octaves do. “ Let it “ not be fuppofed (fays Mr Saveur), that the mufical “ fcale is merely an arbitrary combination of founds ; “ it is made up from the confonance and differences of “ the parts which compofe it. Thofe who have often “ heard a fourth and fifth accord together, will be “ naturally led to difcover their difference at once ; and “ the mind unites itfelf to their beauties.” Let us then ceafe to affign the coincidences of vibrations as the caufe of harmony, fince thefe coincidences in two firings vi¬ brating at different intervals, muft at heft be but for¬ tuitous ; whereas concord is always pleafing. The true caufe why concord is pleafing, muft arife from our power, in fuch a cafe, of meafuring more eafily the differences of the tones. In proportion as the note can be mea- fured with its fundamental tone by large and obvious diftin&ions, then the concord is moft pleafing ; on the contrary, when the ear meafures the difcriminations of two tones by very fmall parts, or cannot meafure them at all, it lofes the beauty of their refemblance: the whole is difcord and pain (c). But there is another property in the vibration of a muficalftringnot yet taken notice of, and which is alleged to confirm the foregoing theory. If we ftrike the ftring of an harpfichord, or any other elaftic founding chord whatever, it returns a continuing found. This till of late was confidered as one fimple uniform tone ; but all S T I C S. 83 muficians now confefs, that inftead of one tone it ac- Of Mufical tually returns four tones, and that conftantly. The, Sounds- _ notes are, befide the fundamental tone, an odlave above, ' v a twelfth above, and a feventeenth. One of the bafs- notes of an harpfichord has been diffefted in this man¬ ner by Rameau, and the adlual exiftence of thefe tones proved beyond a poffibility of being controverted. In fa ft, the experiment is eafily tried ; for if we fmartly ftrike one of the lower keys of an harpfichord, and the'n take the finger brilkly away, a tolerable ear will be able to diftinguifh, that, after the fundamental tone has ceafed, three other fhriller tones will be diftinclly heard; firft the octave above, then the twelfth, and laftly the feventeenth : the octave above is in general almoft mix¬ ed with the fundamental tone, fo as not to be eafily per¬ ceived, except by an ear long habituated to tire minute difcriminations of founds. So that we may obferve,' that the fmalleft tone is heard laft, and the deepeft and largeft one firft : the two others in order. In the whole theory of founds, nothing has given greater room for fpeculation, conjeflure, and difap- pointment, than this amazing property in elaftic firings. The whole ftring is universally acknowledged to be in vibration in all its^ parts, yet this fingle vibration re¬ turns no lefs than four different founds. They who account for the tones of firings by the number of their vibrations, are here at the greateft lofs. Daniel Ber¬ noulli! fuppofes, that a vibrating ftring divides itfelf into a number of curves, each of which has a peculiar vibration ; and though they all fwing together in the common vibrationy yet each vibrates within itfelf. This opinion, which was fupported, as moft geometrical fpeculations are, with the parade of demonftration, was only hern foon after to die. Others have aferibed this to an elaftic difference in the parts of the air, each of which, at different intervals, thus received different impreffions from the ftring, in proportion to their ela- flicity. This is abfurd. If we allow the difference of tone to proceed from the force, and not the frequency, of the vibrations, this difficulty will admit of an eafy folution. Thefe founds, though they feem to exift to¬ gether in the firing, actually follow each other in fuc- ceffion : while the vibration has greateft force, the fundamental tone is brought forward : the force of the vibration decaying, the oclave is produced, but almoft only inftantaneoufly ; to this fucceeds, with diminifhed force, the twelfth ; and, laftly, the feventeenth is heard to vibrate with great diftindlnefs, while the three other tones are always filent. Thefe founds, thus excited, are all of them thef harmonic tones, whofe differences from the fundamental tone are, as was faid, ftrong, and diftindl. On the other hand, the difeordant tones can¬ not be heard. Their differences being but very fmall, they are overpowered, and in a manner drowned in the tones of fuperior difference: yet not always neither ; for Daniel Bernouilli has been able, from the fame ftroke, to make the fame ftring bring out its harmo¬ nic and its difeordant tones alfo (d.) So that from hence we may juflly infer, that every note whatfoever (c) It is certain, that in proportion to the fimplicity of relations in found, the ear is pleafed with its combinations ; but this is not to be admitted as the caufe why muiicians have confined all harmony to an ('Clave. Difcriminated founds, whofe vibrations either never coincide, or at leaft very rarely, do not only ceafe to pjeafe, but violently grate, the ear. Harmony and difcord, therefore, are neither difcriminated by the judgment of hearers, nor the iuilitution of muficians, but by their own efiential and immutable nature. (d) Via.

S(>ur‘ds- diftinftly heard, whofe differences are moft eafily per- ^ ' ceivable. To this theory, however, though it has a plaufible to the prece- aPPcarance> there are ftrong and indeed infuperable time theory, objections. The very fundamental principle of it is I C S. Ch.

So that a greater quantity of coated glafs always gave a deeper note. Differences in the degree of a charge in the fame falfe. No body whatever, whether elaftic or non-ela- jar made little or no difference in the tone of the ex¬ ilic, yields a graver found by being {truck with a large inftrument, unlefs either the founding body, or that part of it which emits the found, is enlarged. In this cafe, the largeft bodies always return the graveft founds. In fpeaking of elaftic and non-elaftic bodies in a i ploffon : if any, a higher charge gave rather a deeper note.” Thefe experiments (how ns how much the gravity or acutenefs of founds depend on the quantity of air put in agitation by the founding body. We know that the noife of the eleftric explofion arifes from the return ffcal fenfe, we are not to pufh the diftin&ion fo far as, of the air into the vacuum produced by the eleftric when we fpeak of them philofophically. A body is mu- ftafh. Tire larger the vacuum, the deeper was the note : fteally elaftic, all of whofe parts are thrown into vibra- for the fame feafon, the difcharge of a mufket produ- tions fo as to emit a found when only part of their fur- face is ftruck. Of this kind are bells, mufical firings^ and all bodies whatever that are confiderably hollow.— Mufical non-elaftics are fuch bodies as emit a found more acute note than that of a cannon j and thunder is deeper than either. r Befides this, however, other circumftances concur to produce different degrees of gravity or acutenefs in only from that particular place which is ftruck : thus, founds. The found of a table ftruck upon with a piece a table, a plate of iron nailed on wood, a bell funk in the earth, are all of them non-elaftics in a mufical fenfe, though not philofophically fo. When a folid bo¬ dy, fuch as a log of wood, is ftruck with a fwitch, only that part of it emits a found which comes in contaft with the fwitch ; the note is acute and loud, but would be no lefs fo though the adjacent parts of the log were removed. If, inftead of the fwitch, a heavier or lar¬ ger inftrument is made ufe of, a larger portion of its furface then returns a found, and the note is confe- quently more grave; but it would not be fo, if the large inftrument ftruck with a ftiarp edge, or a furface only equal to that of the fmall one. In founds of this kind, where there is only a fingh of wood, will not be the fame with that produced from a plate of iron ftruck by the fame piece of wood, even if the blows {hould be exattly equal, and the iron per- feftly kept from vibrating.—Here the founds are gene¬ rally faid to differ in their degrees of acutenefs, accord¬ ing to the fpecific gravities or denfities of the fubftan- ces which emit them. Thus gold, which is the moft denfe of all metals, returns a much graver found than filver; and metalline wires, which are more denfe than therms, return a proportionably greater found.—But neither does this appear to be a general rule in which we can put confidence. Bell-metal is denfer than cop¬ per, but it by no means appears to yield a graver found j on the contrary, it feems very probable, that copper thwack,, without any repetition, the immediate caufe of will give a graver found than bell-metal, if both a the gravity or acutenefs feems to be the quantity of air ftruck upon in their non-elaftic ftate ; and we can by difplaced by the founding body ; a large quantity of no means think that a bell of pure tin, the leaft denfe air difplaced, produces a grave found, and a fmaller quantity a more acute one, the force wherewith the air is difplaced fignifying very little.—What we hear ad¬ vance is confirmed by fome experiments made by Dr Prieftley, concerning the mufical tone of eleftrical dif- charges. The paffage being curious, and not very long, we {hall here tranferibe it: “ As the courfe of my experiments has required a great variety of eleftrical explofions, I could not help obferving a great variety in the mufical tone made by the reports. This excited my curiofity to attempt to reduce this variation to fome meafure. According¬ ly, by the help of a couple of fpinets, and two per- fons who had good ears for mufic, I endeavoured to afeertain the tone of fome eleftrical difeharges; and obferved, that every difcharge made feveral firings, par¬ ticularly thofe that were chords to one another, to vi¬ brate : but one note was always predominant, and founded after the reft. As every explofion was repeat¬ ed feveral times, and three of us feparately took the fame note, there remained no doubt but that the tone we fixed upon was at leaft very near the true one. The refult was as follows: “ A jar containing half a fquare foot of coated glafs founded F ftiarp, concert pitch. Another jar of a dif¬ ferent form, but equal furface, founded the fame. M A jar of three fquare feet founded C below F of all the metals, will give a more acute found than one of bell-metal, which is greatly more denfe.—In fome bodies hardnefs feems to have a confiderable ef- feft. Glafs, which is confiderably harder than any metal, gives a more acute found ; bell-metal is harder than gold, lead, or tin, and therefore founds much, more acutely; though how far this holds with regard to different fubftances, there are not a fufficient number of experiments for us to judge. In bodies mufically elaftic, the whole fubftance vi¬ brates with the flighteft ftroke, and therefore they al¬ ways give the fame note whether they are ftruck with a large or with a fmall inftrument; fo that ftriking a part of the furface of any body mufically elaftic is e- quivalent, in it, to ftriking the whole furface of a non- elaftic one. If the whole furface of a table was ftruck . with another table, the note produced would be neither more nor lefs acute whatever force was employed; be- caufe the whole furface would then yield a found, and no force could increafe the furface: the found would indeed be louder in proportion to the force employed, but the gravity would remain the fame. In like man¬ ner, when a bell, or mufical ftring, is ftruck, the whole fubftance vibrates, and a greater ftroke cannot increafe the fubftance.—Hence we fee the fallacy of what is faid concerning the Pythagorean anvils. An anvil is a body mufically elaftic, and no difference in the tone j-Ch.I. ACOUSTICS. 0 Of Muficalcan be perceived whether it is ftruck with a large, or 1 , Snunds- with a fmall hammer; becaufe either of them are fuf- v ficient to make the whole fubftance vibrate, provided nothing but the anvil is ftruck upon: fmiths, however, do not ftrike their anvils, but red-hot iron laid upon their anvils; and thus the vibrations of the anvil are ftopped, fo that it becomes a non-elaftic body, and the differences of tone in the ftrokes of different hammers proceed only, from the furface of the large hammers covering the whole furface of the iron, or at leaft a greater part of it than the fmall ones. If the fmall hammer is fufficient to cover the whole furface of the iron as well as the large one, the note produced will be the fame, whether the large or the fmall hammer is ufed. JLaftly, The argument for the preceding theory, grounded on the production of what are. called flute- H „ notes on the violin, is built on a falfe foundation ; for the bow being lightly drawn on an open ftring, pro¬ duces no flute-notes^ but only the hartnonies of the note to which the ftring is tuned. The flute-notes are pro¬ duced by a particular motion of the bow, quick and near the bridge, and by fingering very gently. By this management, the fame founds are produced, tho’ at certain intervals only, as if the vibrations were tranf- ferred to the fpace between the end of the finger-board and the finger, inftead of that between the finger and the bridge. Why this fmall part of the ftring fhould vibrate in fuch a cafe, and not that which is under the immediate aftion of the bow, we muft own ourfelves ignorant: nor dare we affirm that the vibrations really are transferred in this manner, only the fame founds are produced as if they were. Though thefe objections feem fufficiently to over¬ turn the foregoing theory, with regard to acute founds being the effefts of weak ftrokes, and grave ones of -ftronger impulfes, we cannot admit that longer or ffiorter vibrations are the occafion of gravity or a- cutenefs in found. A mufical found, however length¬ ened, either by ftring or bell, is only a repetition of a fingle one, whofe duration by itfelf is but for a mo¬ ment, and is therefore termed inappretiable, like the fmack of a whip, or the explofion of an elecftrical bat¬ tery. The continuation of the found is nothing more* than a repetition of this inftantaneous inappretiable noife after the manner of an echo, and it is only this echo that makes the found agreeable. For this reafon, mufic is much more agreeable when played in a large hall where the found is reverberated, than in a fmall room where there is no fuch reverberation. For the fame reafbn, the found of a ftring is more agreeable when put on a hollow violin than when fattened to a plain board, &c.—In the found of a bell, we cannot avoid obferving this echo very diftinCtly. The found appears to be made up of diftinct pulfes, or repetitions of the fame note produced by the ftroke of the hammer. It can by no means be allowed, that the note would be more acute though thefe pulfes were to fucceed one another more rapidly ; the found would indeed become more Ample, but would ftill preferve the fame tone.— In mufical firings the reverberations are vaftly more quick than in bells 5 and therefore their found is more uniform or fimple, and confequently more agreeable * See Ear- than that of bells. In mufical glaffes*, the vibrations Qmaaica. muft be inconceivably quicker than in any bell, or ftringed inftrument: and hence they are of all others 85 the moft fimple and the moft agreeable, though neither Propaga- the moft acute nor the loudeft.—As far as we can judge, quicknefs of vibration contributes to the unifor-, °“n ' , mity, or fimplicity, but not to the acutenefs, nor to the loudnefs, of a mufical note. It may here be objefted, that each of the different pulfes, of which we obferve the found of a bell to be compofed, is of a very perceptible length, and far from being inftantaneous; fo that it is not fair to infer that the found of a bell is only a repetition of a fingle inftan¬ taneous ftroke, feeing it is evidently the repetition of a. lengthened note.—To this it may be replied, that the in¬ appretiable found which is produced by ftriking a bell in a non-elaftic ftate, is the very fame which, being firft propagated round the bell, forms one of thefe fhort pulfes that is afterwards re-echoed as long as the vibra¬ tions of the metal continue, and it is impoffible that the quicknefs of repetition of any found can either in- creafe or diminifti its gravity.

He candidly owns that the demonftration is obfeurely ftated, and takes the li¬ berty of varying, in fome degree, from the method of Newton. “ 1. The parts of all founding bodies, (he obferves), vibrate according to the law of a cycloidal pendulum : for they may be confidered as compofed of an indefi¬ nite number of elaftic fibres; but thefe fibres vibrate according to that law. Fide Heljham, p. 270. “ 2. Sounding bodies propagate their motions on all fides in direftum, by fucceffive condenfations and rare- fa&ions, and fucceffive goings forward and returning^ backward of the particles. Vide prop. 43. B. 2. Newton. “ 3. The pulfes are thofe parts of the air which vi brate backwards and forwards; and which, by going forward, ftrike [pulfant) againft obftacles. The lati¬ tude of a pulfe is the rectilineal fpace through which the motion of the air is propagated during one vibra¬ tion of the founding body. “ 4. All pulfes move equally faft. This is proved by experiment; and it is found that they deferibe 1070 Paris feet, or 1142 London feet in a fecond, whether the found be loud or low, grave or acute. “ 5. Prob. To determine the latitude of a pulfe. Divide the fpace which the pulfe defcribes in a given time (4) by the number of vibrations performed in the fame time by the founding body, {cor. 1. prop. 24. Smith's Harmonics'), the quotient is the latitude. “ M. Sauveur, by fome experiments on organ-pipes, found that a body, which gives the graveft harmonic found, vibrates 12 times and a half in a fecond, and that the flirilleft founding body vibrates 51.100 times in a fecond. At a medium, let us take the body which gives what Sauveur calls his fixed found: it performs 100 vibrations in a fecond, and in the fame time the pulfes deferibe 1070 Parifian feet; therefore the fpace deferibed by the pulfes whilit the body vibrates once, that 86 A C O U S Propaga- that is, the latitude or interval of the pulfe, will be tinn of iO'J feet. ■ . 141) has found by experiment, that the middle point of a chord which produces his -fixed found, and whofe dia¬ meter is 3-th of a line, runs over in its fmalleft fenfible vibrations V-g-th of a line, and in its greateft vibrations 72 times that fpace; that is 72X-1,-gth of a line, or 4 lines, that is, yd of .n inch. “ The latitude of the pulfes of this fixed found is 10.7 feet (5) ; and fince the circumference of a circle is to its radius as 710 is to 113, the greateft fpace defcribed by the particles will be to the radius of a circle, whofe periphery is equal to the latitude of the pulfe as yd of an inch is to 1.7029 feet, or 20.4348 inches, that is, as 1 to 61.3044. “ If the lengtn of the fixing be increafed or diminifti- td in any proportion, cateris paribus, the greateft fpace defcribed by its middle point will vary in the fame proportion. For the inflefting force is to the tending force as the diftance of the fixing from the middle point of vibration to half the length of the fixing \fee Helfham and Martin); and therefore the inflecting and tending forces being given, the fixing will vibrate through fpaces proportional to its length ; but the latitude of the pulfe is inverfely as the number . of vibrations performed by the firing in a given time, (5) that is, direCtly as the time of one vibration, or diredtly as the length of the firing {prop. 24. cor. 7. Smith’s Harmonics) ; therefore the greateft fpace through which the middle point of the firing vibrates, will vary in the direCt ratio of the latitude of the pulfe, or of the radius of a circle whofe circumference is .e- qual to the latitude, that is, it will be to that radius as 1 to 61.3044. “7. If the particles of the aerial pulfes, during any part of their vibration, be fucceffively agitated, accord¬ ing to the law of a cycloidal pendulum, the compara¬ tive elaftic forces arifing from their mutual aCtion, by which they will afterwards be agitated, will be fuch as will caule the particles to continue that motion, accor¬ ding to the fame law, to the end of their vibration.

Thus will the particle E perform its vibrations according to the law of a cycloidal pendulum. Prop. 52. B. 1. Principia. “ Let us fuppofe now, that the particles have been, fucceffively agitated, according to this law, for a cer¬ tain time, by any caufe whatfoever, and let us examine what will be the comparative elaftic forces arifing from their mutual aft ion, by which they will afterwards con¬ tinue to be agitated. “ In the circumference PH S/6 take the equal arches HI, IK in the fame ratio to the whole circumference which the equal right lines EE, EG have to BC the whole interval of the pulfes; and let fall the per¬ pendiculars HL, IM, KN. Since the points E, F, G are fucceffively agitated in the fame manner, and per¬ form their entire vibrations of progrefs and regrefs while the pulfe is propagated from B to C, if PH be the time from the beginning of the motion of E, PI will be the time from the beginning of the motion of F, and PK the time from the beginning of the motion of G; and therefore E£, Fp, Gy will be refpeftively equal to PL, PM, PN in the progrefs of the particles. Whence or EF+Fp—Et is equal to EF—LM. But Ej is the exparifion of EF in the place £?>, and therefore this expanfion is to its mean expanfion as EF—LM to EF. But LM is to IH as IM is to OP, and IH is to EF as the circumference PHS/; is to BC ; that is, as OP is to V, if V be the radius of a circle whofe circumference is BC; therefore, ex aequo, LM is to EF as IM is to V ; and therefore the expanfion of EF in the place is to its mean expanfion as V—IM is to V; and the elaftic force exifting between the phy- fical points E and F is to the mean elaftic force as y—1 is to ^ {Cotes Pncutn. Led. 9.) By the fame argument, the elaftic force exifting between the phy- fical points F and G is to the mean , elaftic force as ■ is to vG and the difference between thefe V—KN V forces is to the mean elaftic force as IM—KN . 1 , . w—v.iM—v.kn+Tm.kn '18 v; hat ^ as IMrd™ is to A or as IM—KN is to V; if on¬ ly (upon account of the very narrow limits of the vi¬ bration) we fuppofe IM and KN to be indefinitely lefs than V. Wherefore, fince V is given, the difference of the forces is as IM—KN, or as HL—IM (becaufe KH is bifefted in I) ; that is, (becaufe HL—IM is to IH as OM is to 01 or OP, and IH and OP are given quantities) as OM; that is, if I/be bifefted in n as np. “ In the fame manner it may be Ihown, that if PHS/6 be the time from the beginning of the motion of E, PH Si will be the time from the beginning of the mo¬ tion of F, and PHSi the time from the beginning of the A C O U the motion of G ; and that the expanfion of EF in the place is to its mean expanfion as EF+Fp—E?, j or as EF+/;» is to EF, or as \-\-hl is to V in its re- grefs ; and its elaflic force- to the mean elaflic force as 5'3 t0 V 5 an<^ '^iat t^e difference of the elaftic forces exifting between E and F, and between F and G is to the mean elaftic force as kn—im is to V; that is, diredUy as ru. “ But this difference of the elaftic forces, exifting be¬ tween E and F, and between F and G, is the com¬ parative elaftic force by which the phyfical point is agitated: and therefore the comparative accelerating force, by which every phyfical point in the medium will continue to be agitated both in progrefs and re- grefs, will be directly as its diftance from the middle point of its vibration ; and confequently, will be fuch as will caufe the particles to continue their motion, un- difturbed, according to the law of a cycloidal pen¬ dulum. Prop. 38. /. t. Newtoti. “ Newton rejects the quantity -fVXlM-bKN-f-IMX KN, on fuppofition that IM and KN are indefinitely lefs than V. Now, although this may be a reafonable hypothefis, yet, that this quantity may be fafely re¬ jected, will, I think, appear in a more fatisfaftory manner from the following confiderations derived from experiment: PS, in its greateft poffible ftate, is to V as 1 is to 61.3044 (6) ;.and therefore IM or KN, in its greateft poflible ftate, (that is, when the vibrations of the body are as great as poffible, and the particle in the middle point of its vibration) is to V as 1 is to 122.6. Hence V*e=i5030.76,—VXlM+KN=245.a and IMxKN=i ; therefore V* is to V*—VXlM-t- KN+IMxKN as 15.03076^0 14786.56; that is, as 61 is to 60 nearly. “ Hence it appears, that the greateft poffible error in the accelerating foxxe, in the middle point, is the -g-Vft part of the whole. In other points it is much lefs; and in the extreme points the error entirely va- nifhes. We fhould alfo obferve, that the ordinary founds we hear are not produced by the greateft poffible vi¬ brations of which the founding body is capable; and that in general IM and KN are nearly evanefcent with refpedt to V. And very probably the difagreeable fen- fations we feel in very loud founds, arife not only from IM or KN bearing a fenftble proportion to V, by which means the cycloidal law of the pulfes may be in fome meafure difturbed, but alfo from the very law of the motion of the founding body itfelf being difturbed. For, the proof of this law’s being obferved by an e- laftic fibre is founded on the hypothefis that the fpace, through which it vibrates, is indefinitely little with re- fpect to the length of the firing. See Smith's Har¬ monics, pi 237, Heljham, p. 270. “ 8. If a particle of the medium be agitated, ac¬ cording to the law of a cycloidal pendulum, the com¬ parative elaftic force, afting on the adjacent particle, from the inftant in which it begins to move, will be fuch as will caufe it to continue its motion according to the fame law. “ For let us fuppofe, that three particles of the me¬ dium had continued to move, for times denoted by the arches PK, PI, PH, the comparative elaftic force, s t 1 c S. 87 a fling on the fecond during the time of its motion, Propaea- would have been denoted by HE—IM, that is, would llon °.f have been diredlly as MO (7). And if this time be k°UJ1 ' ■ diminiffied till I becomes coincident with P, that is, if you take the particles in that ftate when the fecond is juft beginning to move, and before the third particle has yet been fet in motion ; then the point M will fall on P, and MO become PO ; that is, the comparative elaftic force of the fecond particle, at the inftant in which it begins to move, will be to the force with which it is agitated in any other moment of time, be¬ fore the fubfequent particle has yet been fet in motion, directly as its diftacce from the middle point of vibra¬ tion. Now this comparative elaftic force, with which the fecond particle is agitated in the very moment in which it begins to move, arifes from the preceding particle’s approaching it according to the law of a pen¬ dulum ; and therefore, if the preceding particle ap¬ proaches it in this manner, the force by which it will be agitated, in the very moment it begins to move,, will be exactly fuch as ffiould take place in order to move it according to the law of a pendulum.- It there¬ fore fets out according to that law, and confequently the fubfequent elaftic forces, generated in every fuc- ceffive moment, will alfo continue to be of the jufic magnitude which fhould take place, in order to produce; . fuch a motion. “ 9. The pulfes of the air are propagated from’ founding bodies, according to the law of a cycloidal pendulum* The point E of any elaftic fibre pro- Plate L ducing a found, may be confidered as a particle of^fh 7* air vibrating according to the law of a. pendulum (1). This point E will therefore move, according to this law for a certain time, denoted by the arch IH, before the fecond particle begins to move ; for found is pro¬ pagated in time through the fucceffive particles of air (4). Now from that inftant, the comparative elaftic force which agitates F, is (8) diredlly as its diftance from the middle point of vibration. F therefore fets out with a motion according to the law of a pendulum:. and therefore the comparative elaftic force by which it will be agitated until G begins to move, will continue that law (8). Confequently F will approach G in the fame manner as E approached F, and the comparative elaftic force of G, from the inftant in which it begins to move, will be diredlly as its diftance from the middle point of vibration ; and fo on in fucceffion. Therefore all the particles of air in the pulfes fucceffively fet ow from their proper places according to the law of a pen¬ dulum, and therefore (.7) will finifh their, entire vibra¬ tions according to the fame law. “ Cor. 1. The number of pulfes propagated is the fame with the number of vibrations of the tremulous body, nor is it multiplied in their progrefs: becaufe the little phyfical line -"/, (fg. 7.) as foon as it returns to uts proper place, will there quiefce ; for its velocity, which is denoted by the fine IM, then vaniffies, and its denfity becomes the fame with that of the ambient me¬ dium. This line, therefore, will no longer move, un- lefs it be again driven forwards by the impulfe of the founding body, or of the pulfes propagated from it. “ Cor. 2. In the extreme points of the little fpace through which the particle vibrates, the expanfion of the air is in its natural ftate ; for the expanfion of the phyfical line is to its natural expanfion as V -j-IM.is SB A C O U Propaga- to V; but IM is then equal to nothing. In the middle Souncf P°^nt t^ie Progrefs the condenfation is greateft ; for ~‘n. ‘ . IM is then greateft, and confequently the expanfion V—IM leaft. In the middle of the regrefs, the rare- faftion'is greateft; for im, and confequently V+/'», is then greateft. “ 10. To find the velocity of the pulfes, the den- fity and elaftic force of the medium being given. “ This is the 49th prop. B. 2. Newton, in which he ftiows, that whilft a pendulum, whofe length is equal to the height of the homogeneous atmofphere, vibrates once forwards and backwards, the pulfes will defcribe a fpace equal to the periphery of a circle defcribed with that altitude as its radius. “ Cor. 1. He thence ftiows, that the velocity of the pulfes is equal to that which a heavy body would ac¬ quire in falling down half the altitude of that homoge¬ neous atmofphere ; and therefore, that all pulfes move equally fail, whatever be the magnitude of PS, or the time of its being defcribed; that is, whether the tone be loud or low, grave or acute. See Hales de Sonis, § 49* “ Cor. 2. And alfo, that the velocity of the pulfes is in a ratio compounded of the diredt fubduplicate ra¬ tio of the elaftic force of the medium, and the inverfe fubduplicate of its denfity. Hence founds move fome- what fafter in fummer than in winter. See Hales de Sonis, p. 141. “ n. The ftrength of a tone is as the moment of the particles of air. The moment of thefe particles, (the medium being given) is as their velocity ; and the velocity of thefe particles is as the velocity of the firing which fets them In motion (9). The velocities of two different firings are equal when the fpaces which they defcribe in their vibrations are to each other as the times of thefe vibrations: therefore, two different tones are of equal ftrength, when the fpaces, through which the firings producing them vibrate, are dire fitly as the times of their vibration. ad Plate II. “ 12. Let the ftrength of the tones of the two firings AB, CD, which differ in tenfion only (fig. 1, 2.) be equal. Q_uere the ratio of the inflefiling forces F and / From the hypothefis of the equality of the ftrength of the tones, it follows (n), that the fpace GE muft be to the fpace HF as/’•y to F4-, {Smith's Harm. Prop. 24. Cor. 4.) Now the forces inflefiling AB, CD through the equal fpaces GE, HP are to ♦ach other as the 'tending forces, that is, as F toyj [Malcolm's Treatife on Muftc, p. $2.) But the force inflefiling CD. through HP is to the force inflefiling it through HF as HP or GE to HF, 47.) that is, by the hyp. as /'4- to F4-. Therefore, ex a quo, the forces inflefiling AB and CD, when the tones are equally ftrong, are to each other as FX/'4 to or as F4- to f\. That is, the forces neceffary to produce tones of equal ftrength in various firings which differ only in tenfion, are to each other in the fubduplicate ratio of the tending forces, that is, inverfely as the time of one vibration, or direfilly as the number of vibrations per¬ formed in a given time. Thus, if CD be the acute cfilave to AB, its tending force will be quadruple that of AB, {Malcobn's Treatife on Mujic, />. 53) ; and therefore to produce tones of equal ftrength in thefe firings, the force impelling CD muft be double that impelling AB ; and fo in other cafes. N°3- S T I C S. Ch.lL “ Suppofe, now, that the firings AB, CD, (fig. 2, Propaga- 3.) differ in length only. The force inflefiling AB through GE is to the tending force, which is given, as 1 . GEto AG; and this tending force is to the force piaten, inflefiling CD through the fpace HP equal to GE, as HD to HP. Therefore, ex cequo, the forces inflefiling AB and CD through the equal fpaces GE and HP, are to each other as HD to AG, or as CD to AB. But the force inflefiling CD through HP is to the force inflefiling it through HF, as HP or GE to HF, that is, becaufe thefe fpaces are as the times (11), as AB to CD. Therefore, ex cequo, the forces inflefiling AB and CD, when the tones are equally ftrong, are to each other in a ratio of equality. Hence we ftiould fuppofe, that in this cafe, an equal number of equal impulfes would generate equally powerful tones in thefe firings. But we are to obferve, that the longer the firing, the greater, ceeteris parilus, is the fpace through which a given force inflefils it ( Malcolm) ; and therefore what¬ ever diminution is produced in the fpaces through which the firings move in their fucceffive vibrations, arifing either from the want of perfefit elafticity in the firings, or from the refiftance of the air, this diminution will bear a greater proportion to the lefs fpace, through which the fhorter firing vibrates. And this is confirm¬ ed by experience; for we find that the duration of the tone and motion of the whole firing exceeds that of anv of its fubordinate parts. Therefore, after a given in¬ terval of time, a greater quantity of motion will remain in the longer firing; and confequently, after the fuc ceflive equal impulfes have been made, a greater degree of motion will ftill fubfift in it. That is, a given num¬ ber of equal impulfes being made on various firings dif¬ fering in length only, a ftronger found will be produced in that which is the longer." Chap. III. Cf the Velocity, &c. of Sound. Axioms. Experience has taught us, that found travelsatabout Velocity of the rate of 1142 feet in a fecond, or near 13 miles in a found, minute ; nor do any ohftacles hinder its progrefs, a con¬ trary wind only a fmall matter diminifhing its velocity. The method of calculating its progrefs is eafily madc. known. When a gun is difcharged at a diftance, we fee the fire long before we hear the found. If then we know the diftance of the place, and know the time of h* the interval between our firft feeing the fire and then calculated 1 hearing the report, this will fhow us exafilly the time^ cu a e * the found has been travelling to us. For inftance, if the gun is difcharged a mile off, the moment the flafh is feen, you take a watch and count the feconds tillyou hear the found ; the number of feconds is the time the found has been travelling a mile.—Again, by the above ax - iom, we are enabled to find the diftance between ob- jefils that would be otherwife immeafurable. F°r ex-DHlances ample, fuppofe you fee the flafh of a gun in the night at calculated . fea, and tell feven feconds before you hear the report,by means of i it follows therefore, that the diftance is feven times 1142 found- * feet, that is, 24 yards more than a mile and a half. In like manner, if you obferve the number of feconds be¬ tween the lightning and the report of the thunder, you know the diftance of the cloud from whence it pro¬ ceeds. T7 ,, Derham has proved by experience, that all founds ^lefatthl whatever travel at the fame rate. The found of a gun, fame rate. and Ch.III. A C O U Revcbe- an3 the ftriking of a hammer, are equally fwiftin their motions; the fofteft whifper flies as fwiftly, as far as it goes, as the loudeft thunder. To thefe axioms we may add the following. 18 Smooth and clear founds proceed from bodies that are homogeneous, and of an uniform figure ; and harfti or obtufe founds, from fuch as are of a mixed matter and irregular figure. zg The velocity of found is to that of a briflt wind as fifty to one. so The ftrength of founds is greateft in cold and denfe air, and leall in that which is warm and rarefied. ai Every point againft which the pulfes of found {trike, becomes a centre from which a new feries of pulfes are propagated in every direction. 23 Sound defcribes equal fpaces in equal times. Chap. IV. Of Reverberated Sounds. 23' Sound, like light, after it has been refledted from feveral places, may be colledted in one point, as into a focus; and it will be there more audible than in any other part, even than at the place from whence it pro* ceeded. On this principle it is that a whifpering gal¬ lery is conftru&ed. 24 The form of this gallery mult be that of a concave jVhifpering hemifphere ( e ), as ABC; and if a low found or whifper tat’Y’ bs uttered at A, the vibrations expanding themfelves jgi ^ ' every way will impinge on the points DDD, See. and from thence be reflected to EEE, and from thence to the points F and G, till at laft they all meet in C, where, as we have faid, the found will be the moft diftindtly heard. > The augmentation of found by means of fpeaking- ipeaking- trumpets, is ufually illullrated in the following manner: rumpet, Let ABC be the tube, BD the axis, and B the mouth- 4' piece for conveying the voice to the tube. Then it is evident, when a perfon fpeaks at B in the trumpet, the whole force of his voice is fpent upon the air contained in the tube, which will be agitated through the whole length of the tube; and, by various refledlions from the fide of the tube to the axis, the air along the middle part of the tube will be greatly condenfed, and its mo¬ mentum proportionably increafed, fo that when it comes to agitate the air at the ofifice of the tube AC, its force will be as much greater than what it would have been without the tube, as the furface of a fphere, whofe radius is equal to the length of the tube, is greater than the furface of the fegment of fuch a fphere whofe bafe is the orifice of the tube. For a perfon fpeaking at B, without the tube, will have the force of his voice fpent in exciting concentric fuperficies of air all around the point B; and when thofe fuperficies or pulfes of air are diffufed as far as D every way, it is plain the force of the voice will there be diffufed through the whole fu¬ perficies of a fphere whofe radius is BD; but in the trum¬ pet it will be fo confined, that at its exit it will be dif¬ fufed through fo much of that fpherical furface of air as correfponds to the orifice of the tube. But fince the orce is given, its intenfity will be always inverfely as the number of particles it has to move ; and therefore Vo l. I. Parti. S T I C S. in the tube it will be to that without, as the fuperficies of fuch a fphere to the asra of the large end of the tube nearly. But it is obvious, Mr Young obferves, that the con¬ finement of the voice can have little effedt in increafing the ftrength of the found, as this ftrength depends on the-velocity with which the particles move. Were this reafoning conclufive, the voice (hould ifiue through the fmalleft poffible orifice; cylindrical tubes would be pre¬ ferable to any that increafed in diameter; and the lefs the diameter, the greater would be the effedt of the in- ftrument; becaufe the plate or mafs of air to be moved, would, in that cafe, be lefs, and confequently the effefit of the voice the greater; all which is contradidled by muft therefore be derived from fome other principles : and amongft thefe we ftiall probably find, that what the ingenious Kircher hasfuggefted in hisPhonurgia is the moft deferring of our attention. He tells us, that “ the augmentation of the found depends on its refleftion from the tremulous fides of the tube ; which reflections, con* fpiring in propagating the pulfes in the fame diredtion, muft increafe its intenfity.” Newton alfo feemstohave confidered this as the principal caufe, in the fcholium of prop. 50. B. 2. Princip. when he fays, “ we hence fee why founds are fo much increafed in ftentorophonic tubes, for every reciprocal motion is, in each return, increafed by the generating caufe. Farther, when we fpeak in the open air, the effedt on the tympanum of a diftant auditor is produced mere¬ ly by a fingle pulfe. But when we ufe a tube, all the pulfes propagated from the mouth, except thofe in the diredlion of the axis, ftrike againft the fides of the tube, and every point of impulfe becoming a new centre, from whence the pulfes are propagated in all diredtions, a pulfe will arrive at the ear from each of thofe points ; thus, by the ufe of a tube, a greater number of pulfes are propagated to the ear, and confequently the found increafed. The confinement too of the voice-may have fome effedt, though not fuch as is aferibed to it by fome ; for the condenfed pulfes produced by the naked voice, freely expand every way ; but in tubes, the late¬ ral expanfion being diminiftied, the direct expanfion will be increafed, and confequently the velocity of the par¬ ticles, and the intenfity of the found. The fubftance alfo of the tube has its effedt; for it is found by expe¬ riment, that the more elaftic the fubftance of the tube, and confequently the more fufceptible it is of thefe tre¬ mulous motions, the ftronger is the found. If the tube be laid on any non-elaftic fubftance, it deadens the found, becaufe it prevents the vibratory motion of the parts. The found is increafed in-fpeaking- trumpets, if the tube be fufpended in the air ; becaufe the agitations are then carried on without interruption. Thefe tubes {hould increafe in diameter from the mouth¬ piece, becaufe the parts* vibrating in diredtions perpen¬ dicular to the furface, will conlpire in impelling for¬ ward the particles of air, and confequently, by increa-- fing their velocity, will increafe the intenfity of the found: and the furface alfo increafing, the number of points of impulfe and of new propagations will increafe M pro- (e) Acylindric or elliptic arch will anfwer ftill better than one that is circular. 90 A C 0 U i Reverbe- proportionally. Tlie feveral caufes, therefore, of the Sounds increafe °* found in thefe tubes, Mr Young concludes i- . ^ , to be, i. The diminution of the lateral, and confe- quently the ihcreafe of the direft, expanfion and velo¬ city of the included air. 2. The increafe of the num¬ ber of pulfes, by increafing the points of new propaga¬ tion. 3. The refle&ions of the pulfes from the tremu¬ lous fides of the tube, which impel the particles of air forward, and thus increafe their velocity. Echoes An echo is a refle&ion of found ftriking againft fome objedf, as an image is refledted in a glafs : but it has been.difputed what are the proper qualities in a body for thus reflecting founds. It is in general known, that caverns, grottoes, mountains, and ruined buildings, re¬ turn this image of found. We have heard of a very ex¬ traordinary echo, at a ruined fortrefs near Louvain, in Flanders- If a perfon fung, he only heard his own voice,, without any repetition : on the contrary, thofe who flood at fome diftance, heard the echo but not the voice; but then they heard it with furprifing varia¬ tions, fometimes louder, fometimes fofter, now more near, then more diftant. There is an account in the memoirs of the French academy, of afimilar echo near Rouen. As (by n° 21 and 22) every point againft which the pulfes of found ftrike becomes the centre of a new fe- ries of pulfes, and found defcribes . equal diftances in equal times ; therefore, when any found is propagated from a centre, and its pulfes ftrike againft a variety of obftacles, if the fum of the right lines drawn from that point to each of the obftacles, and from each obftacle to a fecond' point,, be equal, then will the later be a point in which an echo will be heard. “ Thus let A be the point from which the found is propagated in all directions, and let the pulfes ftrike againft the obfta¬ cles C, D, E, F, G, H, I, &e- each of thefe points becomes a new centre of pulfes by the firft principle, and therefore from each of them one feries of pulfes will pafs through the point B. Now if the feveral fums of the right lines AC+CB, AD+DB, AE+EB, AG+GB; AH+HB, AI + IB, &c. be all equal to each other, it is obvious that the pulfes propagated from A to thefe points, and again from thefe points to B, will all ar¬ rive at B at the fame inftant, according to the fecond principle ; and therefore, if the hearer be in that point, his ear will at the fame inftant be ftruck by all thefe pulfes. Now it appears from experiment {fee Mujfchen- broek, V. ii. p. 210), that the ear of an exercifed mu- fician can only diftinguifti fuch founds as follow one another at the rate of g or 1 o in a fecond, or any flow¬ er rate : and therefore, for a diftinCt perception of the direft and reflected found, there fliould intervene the interval’ of -^th of a fecond ; but in this time found defcribes i—Li or 127 feet nearly. And therefore, unlefs the fum of the lines drawn from each of the ob¬ ftacles to the points A and' B. exceeds the interval AB by 127 feet, no echo will be heard at B. Since the feveral fums of the lines drawn from the obftacles to the points A and B are of the fame magnitude, it ap¬ pears that the curve pafling through all the points C, D, E, F, G, H, I, &c. will be an ellipfe, (prop.14. B. 2. Ham. Con.) Hence all the points of the obfta- cles. which produce an echo, muft lie in the furface of 2 5 T I C S. Ch. IV. the oblong fphseroid, generated by the revolution of Reverbe- this ellipfe round its major axis. Sounds “ As there may be feveral fphaeroids of different ■ ^ ^. magnitudes, fo there may be feveral different echoes of the fame original found. And as there may happen to be a greater number of reflecting points in the furface of an exterior fphteroid than in that of an interior, a fecond or a third echo may be much more powerful than the firft, provided that the fuperior number of re¬ flecting points, that is, the fuperior number of reflec¬ ted pulfes propagated to the ear, be more than fuffi- cient to compenfate for the decay of found which a- rifes from its being propagated through a greater fpace. This is finely illuftraied in the celebrated echoes at the lake of Killarney in Kerry, where the firft return of the found is much inferior in ftrength to thofe which immediately fucceed it. “ From what has been laid down it appears, that for the moft powerful echo, the founding body Ihould be in one focus of the ellipfe which is the fection of the echo¬ ing fphseroid, and the hearer in the other. However^ an echo may be heard in other fituations, though not fo favourably; as fuch a number of refleCled pulfes may arrive at the fame time at the ear as may be fufficient to. excite a diftinCt perception. Thus a perfon often hears the echo of his own voice ; but for this purpofe he fhould ftand at leaft 63 or 64 feet from the reflect¬ ing obftacle, according to what has been faid before. At the common rate of fpeaking, we pronounce not above three fyllables and an half, that is, feven half fyllables in a fecond ; therefore, that the echo may re¬ turn juft as foon as three fyllables are expreffed, twice the diftance of the fpeaker from the reflecting objeCl muft be equal to 1000 feet; for, as found defcribes 1142 feet in a fecond, ®ths of that fpace, that is, 100a feet nearly, will be defcribed while fix half or three whole fyllables are pronounced : that is, the fpeaker muft ftand near 500 feet from the obftacle. And in general, the diftance of the fpeaker from the echoing furfaee, for any number of fyllables, muft be equal to the feventh part of the produCt ©f 1142 feet multiplied by that number. “ In churches we never hear a diftinCt echo of the voice, but a confuted found when the fpeaker utters his words too rapidly; becaufe the greateft difference of diftance between the direCt and reflected courfes of fuch a number of pulfes as would produce a diftinCt found, is never in any church equal to 12 7 feet, the li¬ mit of echos. “ But though the firft reflected pulfes may produce no echo, both on account of their being too few in¬ number, and too rapid in their return to the ear ; yet it is evident, that the reflecting furface may be fo formed, as that the- pulfes- which come to the ear after two reflections or more may, after having defcribed 127 feet or more, arrive at the ear in fufficient num¬ bers, and alfo fo nearly at the fame- inftant, as to pro¬ duce an echo, though the diftance of the reflecting fur¬ face from the ear be lefs than the limit of echoes. This- is confirmed by a Angular echo in a grotto on the bankr^ of the little brook called the Dinan, about two miles’ from Caftlecomber, in the county of Kilkenny. As- you enter the cave, and continue fpeaking loud, no re¬ turn of the voice is perceived ; but on your arriving at' a* :ch. IV.

Entertaining Experiments and Contrivances. I *7 ~ . HI. TheCon- I.Place aconcave mirror of about two feet diameter, Mverfive Sta-as AB (g), ina perpendicular direction. The focus of ■Plkte I t^1*3 m,"rror may ke fit 15 or 18 inches diftance from Hg 5. * lts ^ur^ce* At the diftance of about five or fix feet fj let there be a partition, in which there is an opening E F, equal to the fize of the mirror ; againft this opening muft be placed a picture, painted in water¬ colours, on a thin cloth, that the found may eafily pafs through it (h). Behind the partition, at the diftance of two or three feet, place another mirror G H, of the fame lize as the former, and let it be diametrically oppofite to it. At the point C let there be placed the figure of a man feated on a pedeftal, and let his ear be placed ex- a£lly in the focus of the firft mirror : his lower jaw muft be made to open by a wire, and ftiut by a fprng; and there may be another wire to move the eyes: thefe ; wires muft pafs through the figure, go under the floor, and come up behind the partition. Let a perfon, properly inftrufted, be placed behind the partition near the mirror. You then propofe to any one to fpeak foftly to the ftatue, by putting his tnouth to the ear of it, afliiring him that it will anfwer inftantly. You then give the fignal to the perfon be¬ hind the partition, who, by placing his ear to the fo¬ cus I, of the mirror G H, will hear diftinffly what the other faid; and, moving the jaw and eyes of the ftatue by the wires, will return an anfwer diredtly, which will in like manner be diftinctly heard by the firft fpeaker. This experiment appears to be taken from the Century of Inventions of the Marquis of Worcef- ter; whofe defigns, at the time they were publiftied, were treated with ridicule and negledt as being im- prafticable, but are now known to be generally, if not univerfally practicable. _ The words of the Marquis are thefe : “ How to make a brazen or ftone head in the midft of a great field or garden, fo artificial and natu- S T I C S. 9t ral, that though a man fpeak ever fo foftly, and even Entertain whifper into the ear thereof, it will prefently open its10* Ex^.c£1* mouth, and refolve the queftion in French, Latin. *nent*’ ^ Welfh, Iriih, orEnglifh, in good terms, uttering it out of its mouth, and then ftiut it until the next queftion be. allied.”—The two following, of a iimilar nature, • appear to have been inventions of Kircher, by means of which (as he informs us *) he ufed to “ utter * Phonur- feigned and ludicrous confultations, with a view to i'aNova, ihow the fallacy and impofture of ancient oracles.” L 'v:'c' r‘ II. Let there be two heads of plafter of Paris, placed, on pedeftals, on the oppofite fides of a room. There muft 1 e .c°m* be a tm tube or an inch diameter, that mult pals rrom the Bafts, ear of one head, through the pedeftal, under the floor, and go up to the mouth of the other. Obferve, that the end of the tube which is next the ear of the one head, Ihould be confiderably larger than that end which comes to the mouth of the other. Let the whole be fo difpofed that there may not be the leaft fufpicion of a communication. Now, when a perfon fpeaks, quite low, into the ear of one bull, the found is reverberated thro’ the length of the tube, and will be diftinctly heard by any one who lhall place his ear to the mouth of the other. It is not neceflary that the tube Ihould come to the lips of the bull.—If there be two tubes, one going to the ear, and the other to the mouth, of each head, two per- fons may converfe together, by applying their mouth and ear reciprocally to the mouth and ear of the bulls; . and at the fame time other perfons that Hand in the middle of the chamber, between the heads, will not hear any part of their converfation. III. Place a bull on a pedeftal in the corner of a 29 room, and let there be two tubes, as in the foregoing The Oracu- amufement, one of which muftgo from the mouth andlar ea * the other from the ear of the bull, through the pedeftal, and the floor, to an under, apartment. There may be likewife wires that go from the under jaw and the eyes of the bull, by which they may be eafily moved. A perfon being placed in the under room, and at a fignal given applying his ear to one of the tubes, will hear any queftion that is allied, and immediately re¬ ply ; moving at the fame time, by means of the wires, the mouth and the eyes of the bull, as if the reply came from it. IV. In a large cafe, fuch as is ufed for dials and fpring- . „ c clocks, the front of which, or at leaft the lower part of nata° ar *** it, muft be of glafs, covered on the infide with gauze, let there be placed a barrel-organ, which, when wound up, is prevented from playing, by a catch that takes a toothed wheel at the end of the barrel. To one end of this catch there mull be joined a wire, at the end of which there is a flat circle of cork, of the fame dimen- fion with the infide of a glafs tube, in which it is to rife and fall. This tube muft communicate with a refer- vo-ir that goes acrofs the front part of the bottom of the cafe, which is to be filled with fpirits, fuch as is ufed in M 2 ther- . (g) Both the mirrors here ufed may be of tin or gilt pafteboard, this experiment not requiring fuch as are very ac¬ curate. (h) The more effedtually to conceal the caufe of this allufion, the mirror AB may be fixed in the wainfcot, and a gauze of any other thin covering thrown over it, as that will not in the lealt prevent the found from being refledled. An experiment of this kind may be performed in a field or garden, between two hedges, in one of which the mirror A B may be placed, and in the other an opening artfully contrived. 02 Entertain- thermometers, hut not coloured, that it may be the jnent^t?1' ^etter concealed by the gauze. * ‘I ' This cafe being placed in the fun, the fpirits will be rarefied by the heat; and riling in the tube, will lift up the catch or trigger, and fet the organ in play : which it will continue to do as long as it is kept in the fun ; for the fpirits cannot run out of the tube, that part of the catch to which the circle is fixed being prevented from rifing beyond a certain point by a check placed over it. When the machine is placed againft the fide of a room on which the fun fhines ftrong, it may conftantly remain in the fame place, if you inclofe it in a fecond. cafe, made of thick wood, and placed at a little di- ftance from the other. When you want it to perform, it will be only neceffary to throw open the door of the outer cafe, and expofe it to the fun. But if the machine be moveable, it will perform in all feafons by being placed before the fire j and in the winter it will more readily flop when removed into the cold. A machine of this fort is. faid to have been invented by Cornelius Dreble, in the laft century. What the conftrudtion of that was, we know not; it might very likely be more complex, but could fcarce anfwer the intention more readily. .j V. Under the keys of a common harpfichord let there Automa- be fixed a barrel, fomething like that in a chamber or- tous Harp-gan, with ftops or pins correfponding to the tunes you fichord. would have it play. Thefe Hops mult be moveable, fo that the tunes may be varied at pleafure. From each of the keys let there go a wire perpendicular down i the ends of thefe wires mull be turned up for about one- fourth. of an inch. Behind thefe wires let there be an iron bar, to prevent them from going too far back. Now, as the barrel turns round, its pins take the ends of the wires, which pull down the keys, and play the harpfichord. The barrel and wares are to be all in- clofed in a cafe. In the chimney of the fame room where the harpfi¬ chord Hands, or at leaft in one adjacent, there mult be a fmoke jack, from whence comes down a wire, or cord, that, palling behind the wainfcot adjoining the chimney, goes under the floor, and up one of the legs Ch.IV. .of the harpfichord, into the cafe, and round a fmall Entertain- | wheel fixed on the axis of that firft mentioned. There | Ihould be pullies at different diftances, behind the wain- , ^ c', fcot and under the floor, to facilitate the motion of the 1 chord. This machinery may be applied to any other keyed inftrument as well as to chimes, and to many other purpofes where a regular continued motion is required. An inftrument of this fort may be confidered as a perpetual motion, according to the vulgar accepta¬ tion of the term ; for it will never ceafe going till the fire be extinguilhed, or fome parts of the machinery be - wrorn out.

At the top of a fummer-houfe, or other building,. 3* f let there be fixed a vane AB, on which is the pinion C, A Ventofal that takes the toothed wheel D, fixed on the axis EF, ^ep”°ny> • which at its other end carries the wheel G, that takes fig. 6. the pinion Hr. All thefe wheels and pinions are to be between the roof and the ceiling of the building. The pinion H is fixed to the perpendicular axis IK, which goes down very near the wall of the. room, and may be covered after the fame manner as are bell-wires: At the lower end of the axis IK there is a fmall pinion L, that takes the wheel M, fixed on the axis of the great w'heel NO. In this wheel there muft be placed a num¬ ber of ftops, correfponding to the tunes it is to play. Thefe ftops. are to be moveable, that the tunes may be altered at pleafure. Againft this wheel there muft hang i 2 fmall bells, anfwering to the notes of the ga¬ mut. Therefore, as the wheel turns round, the ftops ftriking againft the bells, play the feveral tunes. There ftiould be a fly to the great wheel, to regulate its mo¬ tion when the wind is ftrong. The wheel NO, and the bells, are to be inclofed in a cafe. There may be feveral fets of bells, one of which may anfwer to the tenor, another to the treble, and a third to the bafs ; or they may play different tunes, ac¬ cording to the fize of the wheel. As the bells are fmall, if they are of filver, their tone will be the more pleafing. Inftead of bells, glaffes may be here ufed, fo difpo- fed as to move freely at the ftroke of the ftops. This machinery may likewife be applied to a barrel-organ ; and to many other ufes. ACOUSTICS. A C ^cqS ACQS, a town at the foot of the Pyrenaean moun- || tains, in the government of Foix in France.

It took its name from the river running by it; and be¬ ing but two miles from, enjoyed all the conveniences that fhould come by, the fea. It was a place of great flrength, Handing on the top of a very fteep rock, and wafhed on the fouth fide by the river Acragas, now called Fiume di Gergenti, and on the fouth-weft by the Hypfar with a citadel to the fouth-eaft, externally fur- rounded by a deep gulf, which made it inacceffible but on the fide next the town. It was famous for the ty¬ rant Phalaris and his brazen bull. They were a people, luxurious in their tables, and magnificent in their dwell¬ ings; of whom Empedocles, in Diogenes Laertius, fays, that they lived to-day as if they were to die to-morrow, and built as if they were to live for ever.

It was very famous in the time of the crufadoes, and un¬ derwent feveral iieges both by the Chriftians and Sa¬ racens. It is fituated at the north angle of a bay,. which extends in a femicircle of three leagues, as far as the point of Carmel. During the crufades, the poffeffion of this town, was long difputed by the Chriftians and Saracens. In 1192 it was taken from the latter by Richard I. of England and Philip of France, who gave it to the knigfits of St John of Jerufalem, who kept poffeffion of it 100 years, when it was retaken by the Saracens, and almoft entirely deftroyed. This event is rendered memorable by an adl of fingular refolution with which it was accompanied. A number of beautiful young nuns, terrified at the profpedl of being expofed to the brutal lull of the infidels, determined to avoid the vio¬ lation of their chaftity, by rendering themfelves ob- jecls of averfion. With this view they cut off their nofes and mangled their faces. The Saracens, infla¬ med with refentment at a fpe&acle which prevented. the gratification of their appetites, immediately put them all to the fword. After the expulfion of the crufaders, it remained almoft deferted; but in our time has again revived by the induftry of Daher; and the works eredled by Djezzar, within the laft ten years, have rendered it one of the principal towns upon the coaft. The mofq’ue of this Pacha is boafted as a ma- fterpiece of eaftern tafte. The bazar, or covered mar¬ ket, is not inferior even to thofe of Aleppo ; and its public fountam furpaffes in elegance thofe of Damafcus, though the water is of a very indifferent quality. The Pacha has derived the more honour from thefe works, as he was himfelf both the engineer and architect: he formed the plans, drew the defigns, and fuperin- tended the execution. The port of Acre is one of the bell fituated on the coaft, as it is flieltered from the north and north-weft winds by the town itfelf; but it is greatly choaked up fince the time of Fakr-el-din. Djezzar has contented himfelf with making a landing-place for boats. The fortifications, though more frequently repaired than any other in all Syria, are of.no importance: there are only a few wretched low towers, near the port,. on which cannon , are mounted ; and thefe rufty iron , pieces are fo bad, that fome of them burft every time they are fired. Its defence on the land fide is merely a garden-wall, without any ditch. Corn and cotton form the bafis of the commerce of Acre, which is becoming more flourifhing every day,. Of late, the Pacha, by an abufe common throughout all the Turkifh empire, has monopolized all the trade in his own hands ; no cotton can ,be fold but to him,.. and from him every purchafe muft be made. In vain • have the European merchants claimed the privileges granted! ?

Mount Carmel, -which commands it to the fouth, is a flattened cone, and very rocky; it is about 2000 feet high. We ftill find among the brambles wild vines and olive trees, which prove that induftry has formerly been employed even in this un¬ grateful foil: on the fummit is a chapel dedicated to the prophet Elias, which affords an extenfive profpedl over the fea and land.

Acre, the univerfal meafure of land in Britain. The word (formed from the Saxon acher, or the Ger¬ man aker, a field), did not originally fignify a deter¬ mined quantity of land, but any open ground, efpe- cially a wide champaign ; and in this antique fenfe it feems to be preferved in the names of places, as Caftle- acre, Weft-acre, &c. An acre in England contains four fquare roods, a rood 40 perches or poles of 16 J feet each by ftatute. Yet this meafure does not pre¬ vail in all parts of England, as the length of the pole varies in different counties, and is called cujlomary mea¬ fure, the difference running from the 16~ feet to 28. The acre is alfo divided into 10 fquare. chains, of 22 yards each, that is, 4840 fquare yards. An acre in Scotland contains four fquare roods; one fquare rood is 40 fquare falls; one fquare fall, 36 fquare ells; one fquare ell, nine fquare feet and 73 fquare inches ; one fquare foot, 144 fquare inches. The Scots acre is alfo divided into 10 fquare chains; the meafuring chain fhould be 24 ells in length, divided into 100 links, each link 8 inches; and fo one fquare chain will ■contain 10,000 fquare links. The Englifli ftatute-acre is about three roods and fix falls ftandard meafure of Scotland. The French acre, arpent, contains Englifli acre, or 54,450 fquare Englifli feet, whereof the Englifli acre contains only 43,560.—The Stralburg acre is a- bout half an Englifh acre.—The Welfli acre contains commonly two Englifli ones.—The Irifli acre is equal to one acre two roods and 19 perches TVr, Englifli.

Their ftature was lower than that of other * Lib. Hi. I men; they were meagre, and extremely black. In the & xxxix. ' | fpring, high w'eft wands drove from the defart to their AlfoStrabo, quarter locufts of an extraordinary fize, and remarkable1:1)' XV1‘ for the fqualid colour of their wings. So great w»as the number of thefe infefts, that they were the only fuftenance of the barbarians, who took them in the fol¬ low'ing manner: At the diftance of fome ftadia from their habitations there was a wade and deep valley. They filled this valley with wood and wild herbs, with which their country abounded. When the cloud of •locufts appeared, which were driven on by the wind, they fet fire to the fuel wdrich they had collefted. The fmoke w'hich arofe from this immenfe fire was fo thick, that the locufts, in croffing the valley, were ftifled by it, and fell in heaps on the ground. The paffage of the locufts being thus intercepted for many days, they made a large provifion of thofe infefts. As their coun¬ try produced great-quantities of fait, they faked them, to render them more palatable, and to make them keep till the next feafon. This peculiar fupply was their foie food: they had neither herds nor flocks. They were unacquainted with fifhing; for they lived at a dif¬ tance from the fea. They were very adive, and ran with great fwiftnefs. But their life w'as not of long duration; it exceeded not forty years. The clofe of their life was extremely miferable ; for in their old age, winged lice of different, but all of ugly forms, bred in their bodies. This malady, which began in the breaft and belly, foon fpread through the wdiole frame. The patient at firft felt an itching; and the agreeable fen- fation produced by his fcratching of himfelf, preceded a moft deplorable calamity. For when thofe lice, which had bred in his body, forced then- way out, they caufed effufions of corrupt blood, wuth excrucia¬ ting pains in the fldn. The unhappy man, wuth la¬ mentable cries, was induftrious himfelf to make paf- ' fages for them with his nails.

Indeed, as to the credibility of the whole account, we mull leave the reader to judge. But though the circumftances of thefe people ffiould be deemed fabulous, yet may the acridophagia be true. It is well known, that to this day the inhabitants of Ethiopia, Arabia, &£. frequently ufe locufts as food. The reader will not be difpleafed if we lay before him the refult of Dr Haffelquift’s inquiries as to this parti¬ cular, who travelled in Syria and Egypt fo late as the year 1752. This ingenious gentleman, who travelled with a view to improve natural hiitory, informs us, that he alked Franks, and many other people who had lived long in thefe countries, whether they had ever heard that the inhabitants of Arabia, Ethiopia, &c. ufed locufts as food. They anfwered that they had. He likewife afked the fame queftion of Armenians, Cophtes, and Syrians, who lived in Arabia, and had travelled in Syria and near the Red Sea ; fome of whom faid they heard of fuch a practice, and others that they had often feen the people eat thefe in feds. He at laft obtained complete fatisfadion on this head from a learned fheck at Cairo, who had lived fix years in Mec¬ ca. This gentleman told him, in prefence of M. le Grand the principal French interpreter at Cairo, and others, that a famine frequently rages at Mecca when there is a fcarcity of corn in Egypt, which obliges the inhabitants to live upon coarfer food than, ordinary : That when corn is fcarce, the Arabians grind the lo- cufts in hahd-mills, or ftone-mortars, and bake them into cakes, and ufe thefe cakes in place of bread : That he has frequently feen locufts ufed by the Ara¬ bians, even when there was no fcarcity of corn ; but then they boil them, ftew them with butter, and make them into a kind of fricaflee ; which he fayss is not dif- agreeably tafted, for he had fometimes tatted thefe lo- cuft-fricaflees out of curiofity. * Voyage t» A later traveller, Dr Sparrman, informs us *, He Cape, “ That locufts fometimes afford a high treat to vol.i. p. 36..the more unpoliftled and remote hordes of the Hot¬ tentots ; when, as fometimes happens, after an inter¬ val of 8, 10, 15, or 20 years, they make their appear¬ ance in incredible numbers. At thefe times they come from the north, migrating to the fouthward, and do not fuffer themfelves to be impeded by any obftacles, but fly boldly on, and are drowned in the fea whenever they come to it. The females of this race of infedts, which are moft apt to migrate, and are chiefly eaten, are faid not to be able to fly ; partly by reafon of the fhortnefs of their wings, and partly on account of their being heavy and diftended with eggs t and fhort- ly after they have laid thefe in the fand, they are faid to die. It is particularly of thefe that the Hottentots make a brown coffee-coloured foup, which, at the fame time, acquires from the eggs a fat and greafy appear¬ ance. The Hottentots are highly rejoiced at the ar¬ rival of thefe locufts, though they are fure to deftroy every bit of verdure on the ground : but the Hotten¬ tots make themfelves ample amends for this lofs, by falling foul on the animals themfelves, eating them in fuch quantities as in the fpace of a few days to get Acrlfiuj vifibly fatter and in better condition than before.” . jl . The abbe Poiret, alfo, in his Memoir on the Infedls. cro^:lt!Ca of Barbary and Numidia, informs us, “ That the Moors make locufts a part of their food ; that they go to hunt them; fry them in oil and butter ; and fell them publicly at Tunis, at Bonne,” &c. From thefe accounts, we may fee the folly of that difpute among divines about the nature of St John’s food in the wildernefs : fome maintaining the original word to fignify the fruits of certain trees; others, a kind of birds, &c.: but thofe who adhered to the li¬ teral meaning of the text were at leaft the moft ortho* dox, although their arguments were perhaps not fo ftrong as they might have been, had they had an op¬ portunity of quoting fuch authors as the above.

Ariftotle’s le&ures to his difciple* were: of two kinds, exoteric and acroatic. The acroa¬ tic were thofe to which only his own difciples and in¬ timate friends were admitted ; whereas the exoteric were public, and open to all. But there are other dif¬ ferences. The acroatic were fet apart for the higher and more abftrufe fubjefts; the exoteric were employ¬ ed in rhetorical and civil fpeculations. Again, the acroatics were more fubtile and exadt, evidence and de- monftration being here aimed at ;■ the exoterics chiefly aimed at the probable and plaufible. The former wrere the fubjeft of the mornings exercifes in the Lyceum, the latter of the evenings. Add, that the exoterics were publifhed : whereas the acroatics were kept fecret; being either entirely concealed ; or, if they were pub¬ lifhed, it was in fuch obfcure terms, that few' but his owm difciples could be the wafer for them. Hence, when Alexander complained of. his preceptor for pub- lifhing his acroatics, and thus revealing what fhould have been referved to his difciples, Ariftotle anfwered, that they were made public and not public; for that none who had not heard them explained by the author viva voce, wTould underftand them.

ACTIO, in Roman antiquities, an a&ion at law in a court of juftice. The formalities ufed by the Ro¬ mans, in judicial aftions, were thefe : If the difference failed to be made up by friends, the injured pei-fon pro¬ ceeded in jus reum vocare, to fummon the offending party to the court, who was obliged to go, or give bond for his appearance. The offending party might be fummoned into court viva voce, by the plaintiff himfelf meeting the defen¬ dant, declaring his intention to him, and commanding him to go before the magiftrate and make his defence. If he would not go willingly, he might drag and force him along, unlefs he gave fecurity for his appearance on fome appointed day. If he failed to appear on the day agreed on, then the plaintiff, whenfoever he met him, might take him along with him by force, calling any by-ftanders to bear witnefs, by afking them vifne antejlari; the by-ftanders upon this turned their ear to¬ wards him in token of their confent: To this Horace alludes in his Sat. againft the impertinent, Lib. i. Sat. 9. See this further explained under the article An- testari. Both parties being met before the pnetor, or other fupreme magiftrate prefiding in the court, the plaintiff propofed the aftion to the defendant; in which he de- figned to profecute him. This they termed edere ac¬ tionem; and was commonly performed by writing it in a tablet, and offering it to the defendant, that he might fee whether he had better Hand the fuit or com¬ pound. In the next place came the pqflulatio affiants, or the plaintiff’s petition to the praetor, for leave to profecute the defendant in fuch an adtion. The petition was granted by writing at the bottom of it affionem do, or refufed by writing in the fame manner affionem non do. The petition being granted, the plaintiff vadabatur reum, i. e. obliged him to give fureties for his appear¬ ance on fuch 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 tranfaffione, by letting the caufe fall as dubious; or paffiane, by compofition for damages amongft friends. On the day appointed for hearing, the praetor or¬ dered the feveral bills to be read, and the parties fum¬ moned by an accenfus, or beadle. See Accensi. Upon the non-appearance of either party, the de¬ faulter loft his caufe;—if they both appeared, they were faid feJletiffe; and then the plaintiff proceeded litem five affionem intendere, i. e. to prefer his fuit, which was done in a fet form of words, varying accor¬ ding to the difference of the actions. After this the plaintiff defired judgment of the praetor, that is, to be allowed a judex or arbiter, or elfe the recuperatores or centumviri. Thefe he requefted for the hearing and deciding the bufinefs ; but none of them could be de¬ fired but by the confent of both parties. The praetor having affigned them their judges, de¬ fined and determined the number of witneffes to be ad¬ mitted, to hinder the protrading of the fuit; and then the parties proceeded to give their caution, that the ; i ACT [ ior ]' ACT the judgment, whatever it was, flicmld ftand and be per- which before had always been referred to feparate laws} Aft *l formed on both iides.

Action, in phyfiology, is applied to the funftions of the body, whether vital, animal, or natural. The vital funftions, or aftions, are thofe which are As it is neceffary in works of this kind to have a par- abfolutely neceffary to life, and without which there ii ticular regard to the common language of mechanics and philofophers, we have given this double definition: but the proper fignification of the term is the motion no life, as the aftion of the heart, lungs, and arteries. On the aftion and reaftion of the folids and fluids on each other, depend the vital funftions. The pulfe and which a body really produces, or tends to produce, in refpiration are the external figns of life. Vital difeafes another; that is, fuch is the motion it would have pro¬ duced, had nothing hindered its effeft. All power is nothing more than a body aftually in motion, or which tends to move itfelf; that is, a body which would move itfelf if nothing oppofed it. The aftion therefore of a body is rendered evident to us by its motion only ; and confequently we muft not fix any other idea to the word aftion, than that of aftual mo¬ tion, or a fimple tendency to motion. The famous que- ftion relating to vis viva, and vis mortua, owes, in all probability, its exiftence to an inadequate idea of the are all thofe which hinder the influx of the venous blood into the cavities of the heart, and the expulfion of the arterial blood from the fame.—The natural funftions are thofe which are inftrumental in repairing the feveral Ioffes which the body fuflains; for life is deftruftive of itfelf, its very offices occafioning a perpetual wafte. The manducation of food, the deglutition and digeftion thereof, alfo the feparation and dillribution of the chyle and excrementitious parts, &c. are under the head of natural funftions, as by thefe our aliment is converted into our nature. They are neceffary to the continuanc word aftion ; for had Leibnitz and his followers obfer- of our bodies.—The animal funftions are thofe which ved, that the only precife and diftinft idea we can give we perform at .will, as mufcular motion, and all the vo¬ te the word force or aftion, reduces it to its effeft, that luntary aftions of the body : they are thofe which con- is, to the motion it aftually produces or tends to pro- ftitute the fenfes of touch, tafte, fmell, fight, hearing ; duce, they would never have made that curious diflinc- perception, reafoning, imagination, memory, judg- tion. ment, affeftions of the mind. - Without any, or all Quantity of Action, a name given by M. de Mau- of them, a man may live, but not fo comfortably as pertuis, in the Memoirs of the Parifian Academy of with them.

ACTIVE, denotes fomething that communicates adlion or motion to another ; in which acceptation it Hands oppofed to pafiive. Active, in grammar, is applied to fuch words as cxprefs adtion ; and is therefore oppofed to paffive. The adtive performs the action, as the paffive receives it. Thus we fay, a verb affive, a conjugation adive, &c. or an attive participle.

Neuter verbs alfo denote an adtion, but are diftinguiffied from adtive verbs, in that they cannot have a noun following them: fuch are, To Jleep, to go, dsV.—Some grammarians, however, make three kinds of adtive verbs : the tranfitive, where the adtion palfes into a fubjedt different from the agent; reflefted, where the adtion returns upon the agent; and reciprocal, where the adtion turns mutually upon the two agents who produced it.

ACTIUS, in mythology, a furname of Apollo, from Adtium, where lie was vvorfliipped.

This water is whitifh, to the tafte it is fweetifli, with a mixture of the fame bitter which is in the Epfom water. The fait of this water is not quite fo foft as that of Epfom ; and is more calcareous than 2 it, being more of the nature of the fait of lime : for a Adfor. quantity of the Adton water being boiled high, on be- u‘-‘—1 ing mixed with a folution of fublimate in pure water, threw down a yellow fediment. The fait of the Adton water is more nitrous than that of Epfom ; it ftrikes a deep red, or purple, with the tindture of logwood in brandy, as is ufual with nitrous fitlts; it does not pre¬ cipitate filver out of the fpirit of nitre, as common fait does : li- lb of this water yields 48 grains of fait. ACTOR, in general, fignifies a perfon who adts or performs fomething. Actor, among Civilians, the prodtor or advocate in civil courts or caufes : as, Ador ecclefus has been fometimes ufed for the advocate of the church ; ador dominicus fqr the lord’s attorney ; ador villa, the ftew- ard or head bailiff of a village. ► Actor, in the drama, is a perfon who reprefents fome part or charadter upon the theatre. The drama confifted originally of nothing more than a fimple cho¬ rus, who fung hymns in honour of Bacchus ; fo that the primitive adtors were only fingers and muficians. Thefpis was the firft that, in order to eafe this un¬ formed chorus, introduced a declaimer, who repeated fome heroic or comic adventure. Affchylus, finding a fingle perfon tirefome, attempted to introduce a fe- cond, and changed the ancient recitals into dialogues. He alfo dreffed his adtors in a more majeftic manner, and introduced the cothurnus or bulkin. Sophocles added a third, in order to reprefent the various incidents in a more natural manner; and here the Greeks flopped, at leaft we do not find in any of their tragedies above three perfons in the fame feene. Perhaps they looked upon it as a rule of the dramatic poem, never to admit more than three fpeakers at a time on the ftage ; a rule which Horace has expreffed in the following verfe : Nec quart a loqui perfona labor et. This, however, did not prevent their increafing the number of adtors in comedy. Before the opening of a play, they named their adlors in full theatre, together with the parts they were to perform. The ancient ac tors were malked, and obliged to raife their voice ex¬ tremely, in order to make themfelves heard by the in¬ numerable crowd of people who filled the amphitheatres: they were accompanied with a player on the flute, who played a prelude, gave them the tone, and played while they declaimed. Horace fpeaks of a kind of feconda- ry adtors, in his time, whole bufinefs was to imitate the firft ; and leffen themfelves, to become better foils to their principals. The moderns have introduced an infinite number oi adtors upon the ftage. This heightens the trouble and diftrefs that ffiould reign there, and makes a diverfity, in which the fpedtator is fure to be interefted. Adtors were highly honoured at Athens. At Rome they were defpifed, and not only denied all rank among the citizens, but even when any citizen appeared upon the ftage he was expelled his tribe and deprived of the right of fuffrage by cenfors. Cicero, indeed, efteems the talents of Rofcius: but he values his virtues ftili more ; virtues which diftingui/hed him fo remarkably above all others of his profeffion, that they feemed to have excluded him from the theatre. The French have, in this refpedt, adopted the ideas of the Romans ; and the Englifti thofe of the Greeks. Actor, the name of feveral perfons in fabulous hi- ftory.

The Ma¬ hometans tell us, that our firft parents having been thrown headlong from the celeftial paradife, Adam fell upon the ifle of Serendib, or Ceylon, in the Eaft-In- dies; and Eve on lodda, a port of the Red Sea, not far from Mecca. After a feparation of upwards of 200 years, they met in Ceylon, where they multiplied: . according to fome Eve had twenty, according to others only eight, deliveries; bringing forth at each time twins, a male and a female, who afterwards married. The Rabbins imagine that Eve brought forth Cain and Abel at a birth; that Adam wept for Abel an hundred years in the valley of tears near Hebron, du¬ ring which time he did not cohabit with his wife ; and that this feparation would probably have continued longer, had it not been forbid by the angel Gabriel. The inhabitants of Ceylon affirm, that the fait lake on the mountain of Colembo confifts wholly of the tears which Eve for one hundred years together filed becaufe of Abel’s death. Some of the Arabians tell us, that Adam was bu¬ ried near Mecca on Mount Abukobeis; others, that Noah, having laid his body in the ark, caufed it to be carried after the deluge to Jerufalem by Melchife- dek the fon of Shem : of this opinion are the eaftern Chriftians ; but the Perfians affirm that he was interred ip. the ilk of Sereadib, where his corps was guarded by lions at the time the giants warred upon one another.— Adam St Jerom imagined that Adam was buried at Hebron ; others, on Mount Calvary. Some are of opinion that , he died on the very fpot where Jerufalem was after¬ wards built; and was buried on the place where Chrift fuffered, that fo his bones might be fprinkled with the Saviour’s blood ! ! ! Ada»j (Melchior) lived in the 17th century. He was born in the territory of Grotkaw in Silefia, and educated in the college of Brieg, where the dukes of that name, to the utmoft of their power, encouraged learning and the reformed religion as profeffed by Cal¬ vin. Here he became a firm Proteftant; and was ena¬ bled to purfue his ftudies by the liberality of a perfon of quality, who had left feveral exhibitions for young Undents. He was appointed reftor of a college at Heidelberg, where he publilhed his firft volume of il- luftrious men in the year 1615. This volume, which, confifted of philofophers, poets, writers on polite lite¬ rature, and hiftorians, &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 phyficians : the two laft were publilhed in 1620. All the learned men, whofe lives are-contained in thefe four volumes, lived in the 16th, or beginning of the 17th century, and are either Germans or Flemings ; but he publilhed in 1618 the lives of twenty divines of other countries in a feparate volume. All his divines are Pro- teftants. The Lutherans were not pleafed with him, for they thought him partial; nor will they allow his work to be a proper ftandard whereby to judge of the learning of Germany. He wrote other works befidea his lives, and died in 1622. Adam's Apple, a name given to a fpecies of Citrus. Adam’s Needle. See Yucca.

He maintained, that there ought to be no diftindion be¬ tween priefts and laymen, and that fomication and adul¬ tery were meritorious adions. Tanchelin had a great number of followers, and was conftantly attended by 3000 of thefe profligates in arms. His fed did not, however, continue long after his death: but another ap¬ peared under the name of Turlupins, in Savoy and Dau- phiny, where they committed the moft brutal adions in open day. About the beginning of the fifteenth century, one Picard, a native of Flanders, fpread thefe errors in Germany and Bohemia, particularly in the army of the famous Zifca, notwithftanding the fevere difcipline he maintained.

In the month of June of the fame year, Mary queen of Scots being delivered of a fon, afterwards James VI. of Scotland and Firft of England, Mr Adamfon wrote a Latin poem on the occafion. This proof of his loyalty involved him in fome difficulties, having been confined in France for fix months; nor would he have eafily got off, had not Queen Mary, and fome of the principal nobility, interefled themfelves in his behalf. As foon as he re¬ covered his liberty, he retired with his pupil to Bour- ges. He was in this city during the maffacre at Paris; and the fame perfecuting fpirit prevailing among the catholics at Bourges as at the metropolis, he lived concealed for feven months in a public houfe, the ma¬ fter of which, upwards of 70 years of age, was thrown from the top thereof, and had his brains daflied out, for his charity to heretics. Whilll Mr Adamfon lay thus in his fepulchre, as he called it, he wrote his La¬ tin poetical verfion of the Book of Job, and his Tra¬ gedy of Herod in the fame language. In the year 1573, he returned to Scotland; and, having entered into holy orders, became minifter of Paifley. In the year 1575, he was appointed one of the commiffioners, by the general affembly, to fettle the jurifdidtion and po- 3 licy of the church ; and the following year he was na- Adana, med, with Mr David Lindfay, to report their proceed- -v—** ings to the earl of Mdrtoun, then regent. About this time the earl made him one of his chaplains ; and, on the death of bifliop Douglas, promoted him to the archiepifcopal fee of St Andrew’s, a dignity which brought upon him great trouble and unealinefs: for now the clamour of the Prefbyterian party rofe very high a- gainft him, and many inconfiftent abfurd ftories were propagated concerning him. Soon after his promo¬ tion, he publiflied his catechifm in Latin verfe, a work highly approved even by his enemies; but, ne- verthelefs, they ftill continued to perfecute him with great violence. In 1578, he fubmitted himfelf to the general affembly, which procured him peace but for a very little time ; for, the year following, they brought frefli accufations againll him. In the year 1582, being attacked with a grievous difeafe, in which the phyficians could give him no relief, he happened to take a fimple medicine from an old woman, which did him fervice. The woman, whofe name was Alifon Pearfon, was thereupon charged with witchcraft, and committed to prifon, but efcaped out of her confinement; however, about four years afterwards, five was again found and burnt for a witch. In 1583, king James came to St Andrew’s; and the archbifliop, being much recovered, preached before him, and difputed with Mr Andrew Melvil, in prefence of his Majefty, with great reputation, which drew upon him frefli calumny and perfecution. The king, however, was fo well pleafed with him, that he fent him embaffador to Queen Eli- fabeth, at whofe court he refided for fome years. His conduct, during his embaffy, has been varioufly report¬ ed by different authors. Two things he principally laboured, viz. the recommenditig the king his mafter to the nobility and gentry of England, and the pro¬ curing fome fupport for the epifcopal party in Scotland. By his eloquent preaching, he drew after him fuch crowds of people, and raifed in their minds fuch a high idea of the young king his mafter, that queen Elizabeth forbad him to enter the pulpit during his flay in her dominions. In 1584, he was recalled, and fat in the parliament held in Auguft at Edinburgh. The Prefby- terian party was ftill very violent againft the archbi¬ fliop. A provincial fynod was held at St Andrew’s in April 1586: the archbifhop was here accufed and excommunicated: he appealed to the king and the ftates, but this availed him little ; for the mob being excited againft him, he durft fcarce appear in public. At the next general affembly, a paper being pro¬ duced, containing the archbifliop’s fubmiflion, he was abfolved from the excommunication. In 1588, frefli accufations were brought againft him. The year fol¬ lowing, he publiflied the Lamentations of the pro¬ phet Jeremiah in Latin verfe ; which he dedicated to the king, complaining of his hard ufage. In the lat¬ ter end of the fame year, he publiflied a tranflation of the Apocalypfe, in Latin verfe ; and a copy of Latin verfes, addreffed alfo to his Majefty, when he was in great diftrefs. The king, however, was fo far from giving him affiftance, that he granted the revenue of his fee to the duke of Lennox ; fo that the remaining part of this prelate’s lift: was very wretched, he having hardly fubfiftence for his family. He died in 1591. ADANA, a town of Afia, in Natolia, and in the O 2 province ADA [ i°8 ] ADA A'kiifnnia. province of Carmania.

ADANSONIA, Ethiopian Sour-gourd, Mon- kies-bread, or African Calabash-tree, a genus of the monodelphia order, belonging to the polyandria clafs of plants ; the characters of which are : The cafyx is a perianthium one-leav’d, half five-cleft, cup-form, (the divifions revolute), deciduous: The corolla con- fifts of five petals, roundilh, nerved, revolute, growing reciprocally with the claws and ftamina : The Jlamina have numerous filaments, coalefced beneath into a tube, and crowning it, expanding horizontally ; the anthene kidney-form, incumbent: The piflillum has an egged germ ; the ftylus very long, tubular, varionfly intorted; the ftigmata numerous (10) prifmatic, villous, ray-ex¬ panded : The pericarpium is an. oval capfule, woody, not gaping, 10-celled, with farinaceous pulp, the par¬ titions membranous: The feeds are numerous, kidney- fhaped, rather bony, and involved in a friable pulp. There is at prefent but one known fpecies belonging to this genus, the Baobab, which is perhaps the lar- geft production of the whole vegetable kingdom. It is a native of Africa. The trunk is not above 12 or 15 feet high, but from 65 to 78 feet round. The loweft branches extend al- moft horizontally; and as they are about 60 feet in length, their own weight bends their extremities to the ground, and thus^form an hemifpherical mafs of ver¬ dure of about 120 or 130 feet diameter. The roots extend as far as the branches: that in the middle forms a pivot, which penetrates a great way into the earth ; the reft fpread near the furface. The flowers are in proportion to the fize of the tree : and are followed by an oblong fruit, pointed at both ends, about 10 inches long, five or fix broad, and covered with a kind of greenifh down, under which is a ligneous rind, hard and almoft black, marked with rays which divide it lengthwife into fides. The fruit hangs to the tree by a pedicle two feet long and an inch diameter. It con¬ tains a whitifh fpongy juicy fubftance ; with feeds of a brown colour, and ftiaped like a kidney-bean. The bark of this tree is nearly an inch thick, of an afli- coloured grey, greafy to the touch, bright, and very fmootk : the outfide is covered with a kind of varnifh; and the infide is green, fpeckled with red. The wood is white, and veryfoft; the firft flioots of the year are green and downy. The leaves of the young plants are entire, of an ob¬ long form, about four or five inches long, and almoft three broad, towards the top, having feveral veins run¬ ning from the middle rib; they are of a lucid green Adan colour. As the plants advance in height, the leaves ' alter, and are divided into three parts, and afterwards into five lobes, which fpread out in the fhape of an hand. The tree ftieds its leaves in November, and new ones begin to appear in June. It flowers in July, and the fruit ripens in OCtober and November. It is very common in Senegal, and the Cape de Verd iflands; and is found 100 leagues up the country at Gulatn, and upon the fea-coaft as far as Siefra-leona. The age of this tree is perhaps no lefs remarkable than its enormous fize. Mr Adanfon relates, that in a botanical excurfion to the Magdalene Iflands, in the neighbourhood of Goree, he difeovered fome calabafh- trees, from five to fix feet diameter, on the bark of which were engraved or cut to a confiderable depth a number of European names. Two of thefe names, which he was at the trouble to repair, were dated one the I4th, the other the \fh century. The letters were about fix inches long, but in breadth they occu¬ pied a very fmall part only of the circumference of the trunk: from whence he concluded they had not been cut when thefe trees were young. Thefe inferiptions, however, he thinks fufficient to determine pretty nearly the age which thefe calabalh-trees may attain; for even fuppofing that thofe in queftion were cut in their early years, and that trees grew to the diameter of fix feet in two centuries, as the engraved letters evince, how many centuries muft be requifite to give them a dia¬ meter of 25 feet, which perhaps is not the laft term of their growth! The inferibed trees mentioned by this ingenious Frenchman had been feen in 1555, almoft two centuries before, by Thevet, who mentions them in the relation of his voyage to Terra Antarctica or Auftralis. Adanfon faw them in 1749. The virtues and ufes of this tree and its fruit are various. The negroes of Senegal dry the bark and leaves in the ftiaded air; and then reduce them to powder, which is of a pretty good green colour. This powder they preferve in' bags of linen or cot¬ ton, and call it Hilo. They ufe it every day, putting two or three pinches of it into a mefs, whatever it happens to be, as we do pepper and fait: but their view is, not to give a relfth to their food, but to'pre¬ ferve a perpetual and plentiful perfpiration, and to at¬ temper the too great heat of the blood ; purpofes which it certainly anfwers, as feveral Europeans have proved by repeated experiments, preferving themfelves from the epidemic fever, which, in that country, de- ftroys Europeans like the plague, and generally rages during' the months of September and Oftober, when, the rains having fuddenly ceafed, the fun-exhales the water left by them upon the ground, and fills the air with a noxious vapour. M. Adanfon, in that critical feafon, made a light ptifan of the leaves of the baobab, which he had gathered in the Auguft of the preceding year, and had dried in the fliade ; and drank conftantly about a pint of it every morning, either before dr af¬ ter breakfaft, and the fame quantity of it every even¬ ing after the heat of the fun began to abate; he alfo fometimes took the fame quantity in the middle of the day, but this was only when he felt fome fymptoms of an approaching fever. By this precaution he prefer- ved himfelf, during the five years he refided at Senegal, from the. diarrhoea and fever, which are fo fatal there, and ADA [ i Adanfonia and which are, however, the only dangerous difeafes A jj^ of, the place; and other officers fuffered very feverely, i ' / only one excepted, upon whom M. Adanfon prevailed to ufe this remedy, which for its limplicity was defpi- fed by the reft. This ptifan alone alfo prevents that heat of urine which is common in thefe parts, from the month of July to November, provided the perfon ab- ftains from wine. The fruit is not lefs ufeful than the leaves and the bark. The pulp that envelopes the feeds has an agree¬ able acid tafte, and is eaten for pleafure: it is alfo dried and powdered, and thus ufed medicinally in pefti- lential fevers, the dyfentery, and bloody flux; the dofe is a drachm, puffed through a line lieve, taken either in common water, or in an infulion of the plantain. This powder is brought into Europe under the name of terra Jig:Hat,2 lemnta. The woody bark of the fruit, and the fruit itfelf when fpciled, helps to fupply the ne¬ groes with an excellent foap, which they make by drawing a ley from the afties, and boiling it with palm- oil that begins to be rancid. The trunks of fuch of thefe trees as are decayed, the negroes hollow out into burying places for their poets, muficians, buffoons: perfons of thefe charatfers they efteem greatly while they live, fuppofing them to de¬ rive their fuperior talents from forcery or a commerce with demons; but they regard their bodies with a kind of horror when dead, and will riot give them burial in the ufual manner, neither fuffering them to be put into the ground, nor thrown into the fea or any river, be- caufe they imagine that the water would not then nou- rifli the fifh, nor the earth produce its. fruits. The bo- . dies fnut up in thefe trunks become perfectly dry with¬ out rotting, and form a kind of mummies without the help of embalment. The baobab is very diftinft from the calabafti-tree of America, with which it has been confounded by father Labat. See Crescentia. Culture. This tree is propagated from feeds, which are brought from the countries where they grow na¬ turally. Being natives only of hot climates, the plants will not thrive in the open air in Britain, even in fum- mer. The feeds are therefore to be fawn in pots, and plunged into a hot-bed, where the plants will appear in about fix weeks, and in a ftiort time after be fit to tranfplant. They muft then be planted each in. a fe- parate pot, in light fandy earth, and plunged into a hot-bed, ftiading them until they have taken root: af¬ ter which they fhould have frefh air admitted every day in warai weather : but muft be fparingly watered, as being apt to rot. They grow quickly for two or three years, but afterwards make little progrefs ; the lower part of the ftem then begins to fwell, and put out la¬ teral branches, inclining to a horizontal poiition, and covered with a light grey bark. Some of this kind of plants were raifed from feeds obtained from Grand Cairo by Dr William Sherard, in 1724, and were grown to the height of 18 feet; but were all deftroyed by the fevere froft in 1740; after which they were un¬ known in Britain till the return of Mr Adanfon to Pa¬ ris in 1754.

ADDISON (Lancelot), fon of Lancelot Addifon a clergyman, was born at Mouldifmeaburne, in the pa¬ rish of Crofby Ravenfworth in Weftmoreland, in the year 1632. He was educated at Queen’s College, Ox¬ ford ; and at the Reftoration of king CharlesII. accept¬ ed of the chaplain fliip of the garrifon of Dunkirk : but that fortrefs being delivered up to the French in 1662, he returned to England, and was foon after made chaplain to the garrifon of Tangier; where he continued feven years, and was greatly efteemed. In 1670, he returned to England, and was made chaplain in ordinary to the king; but his chaplainfhip of Tangier being taken from him on account of his abfence, he found himfelf ftraitened in his circumftances, when he feafonably obtained the reftory of Milfton in Wiltfhire, worth about 120I. per annum. He afterwards became a prebendaiy of Sarum ; took his degree of doftor of divinity at Oxford; and in 1683 was made dean of Litchfield, and the next year archdeacon of Coventry. His life was exemplary ; his converfation pleafing, and greatly inflruftive ; and his behaviour as a gentleman, a clergyman, and a neighbour, did honour to the place of his refidence. He wrote, X. A Short Narrative of the Revolutions of the Kingdoms of Fez and Morocco : 2. The prefent Hiftory of the Jews: 3. A Difcourfe on Catechifing: 4. A Modeft Plea for the Clergy : 5. An Introdu&ion to the Sacrament: 6. The firft State of Mahometifm : and feveral other pieces. This worthy divine died on the 20th of April 1703 and left threeTons: Jofeph, the fubjedl of the next article; Gulfton, who died while governor of Fort St George ; Lancelot, mafter of arts, and fellow of Magdalen Col¬ lege in Oxford ; and one daughter, firft married to Dr ■Sartre prebendary of Weftminfter, and afterwards to Daniel Combes, Efq. Addison (Jofeph), fon of dean Addifon the fub- jett of the laft article. He was born at Milfton, near Ambrelbury, in Wiltihire, on the IIth of May 1672 ; and not being thought likely to live, was baptized the fame day. He received the firft rudiments of his edu¬ cation at the place of his nativity, under the reverend Mr Nailh ; but was foon removed to Salisbury, under the care of Mr Taylor ; and from thence to the char- ter-houfe, where he commenced his acquaintance with Sir Richard Steele. About fifteen, he was entered at Queen’s College, Oxford, where he applied very clofe- ly to the ftudy of claffical learning, in which he made a furprifing proficiency. In the year 1687, Dr Lancafter, dean of Magda¬ len College, having, by chance, feen a Latin poem of Mr Addifon’s, was fo pleafed with it, that he im¬ mediately got him elefted into that houfe, where he took up his degrees of bachelor and mafter of arts. His Latin pieces in the courfe of a few years, were exceeding¬ ly admired in both univerfities; norwere theylefs efteem¬ ed abroad, particularly by the celebrated Boileau, who is reported to have faid, that he would not have written againft Pcrrault, had he before feen fuch excellent pieces by a modern hand. He publifiied nothing in Englilh before the twenty-fecond year of his age ; when there appeared a fiiort copy of verfes written by him, and ad- dreffed to Mr Dryden, which procured him great re- - putation from the beft judges. This was foon follow¬ ed by a tranflation of the Fourth Georgic of Virgil, (omitting the ftory of Ariftaeus), much commended by Mr Dryden. He wrote alfo the Effay on the Geor¬ gies, prefixed to Mr Dryden’s tranflation. There are feveral other pieces written by him about this time ; amongft the reft, one dated the 3d of April 1694, addrefled to H. S. that is. Dr Sacheverel, who be¬ came afterwards fo famous, and with whom Mr Addi¬ fon lived once in the greateft friendfliip ; but their in¬ timacy was fome time after broken offby their difagree- ment in political principles. In the year 1695, he wrote a poem to king William on one of his cam¬ paigns, addrefled to Sir John Somers lord keeper of the great feal. This gentleman received it with great pleafure, took the author into the number of his friends, and beftowed on him many marks of his favour. Mr Addifon had been clofely prefled, while at the uni- verfity, to enter into holy orders ; and had once refolved upon it: but his great modefty, his natural diffidence, and an uncommonly delicate fenfe of the importance of the facred function, made him afterwards alter his re- folution ; and having exprefled an inclination to travel, he was encouraged thereto by his patron above-men¬ tioned, who by his intereft procured him from the crown a penfion of L. 300 per annum to fupport him in his travels. He accordingly made a tour to Italy in the year 1699 ; and, in 1701, he wrote a poetical epiftle from Italy to the earl of Halifax, which has been univerfally efteemed as a moft excellent perform¬ ance. It was tranflated into Italian verfe by the abbot Antonio Maria Salvini, Greek profeflbr at Florence. In the year 1705, he publiflied an account of his tra¬ vels, dedicated to lord Somers; which, though at firft but indifferently received, yet in a little time met with its deferred applaufe. In the year 1702, he was about to return to Eng¬ land, 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 hap¬ pening foon after, put an end to this affair as well as his penfion ; and he remained for a confiderable time un¬ employed. But an unexpected incident at once raifed him, and gave him an opportunity of exerting his fine talents to advantage : for in the year 1704, the lord treafurer Godolphin happened to complain to lord Ha¬ lifax, that the duke of Marlborough’s victory at Blen¬ heim had not been celebrated in verfe in the manner it deferved ; and intimated, that he would take it kindly, if his lordfliip, who was the known patron of the poets, would name a gentleman capable of doing juftice to fo elevated a fubjeCt. Lord Halifax replied, fomewhat haftily, that he did know fuch a perfon, but would not mention him ; adding, that long had he feen, with indignation, men of no merit maintained in luxury at 'the public expence, whilft thofe of real worth and mo¬ defty were fuffered to languiih in obfeurity. The treafurer anfwered very coolly, that he was forry there ftiould be occafion for fuch an obfervation, but that he would do his endeavour to wipe off fuch reproaches for the ADD the future ; and he engaged his hononr, that whoever his lordfhip named, as a perfon capable of celebrating this vi&ory, fhould meet with a hiitable recompence. JLord Halifax thereupon named Mr Addifon ; inlifting, hows eer, that the treafurer himfelf ftiould fend to him; wb-'ch he promifed. Accordingly he prevailed on Mr Bby’i: (afterwards lord Carlton) then chancellor of the exchequer, to make the propcfal to Mr Addifon ; which he did in fo polite a manner, that our author readily undertook the talk. The lord-treafurer had a light of the piece, when it was carried no farther than the celebrated fimile of the angel; and was lb pleafed with it, that he immediately appointed Mr Addifon a commiffioner of appeals, vacant by the promotion of Mr Locke, chofen one of the lords commiftioners for trade. The Campaign is addrefled to the duke pf Marlborough ; it gives a Ihort view of the military tranfactions in 1704, and contains a noble defcription of the two great aftions at Schellemberg and Blen¬ heim. In 1705, he attended lord Halifax to Hano¬ ver; and* the enfuing year was appointed under-fecre- tary to Sir Charles Hedges fecretary of Hate ; in which office he acquitted himfelf fo well, that the earl of Sun¬ derland, who fucceeded Sir Charles in December, con¬ tinued Mr Addifon in his employment. A tafte for operas beginning at this time to prevail in England, and many perfons having folicited Mr Ad¬ difon to write one, he complied with their requeft, and compofed his Rofamond. This, however, whether from the defeft of the mufic, or from the prejudices in favour of the Italian tafte, did not fucceed upon the ftage ; but the poetry of it has, and always will be, juftly admiredv About this time, Sir Richard Steele compofed his comedy of the Tender Hulband, to which Mr Addifon wrote a prologue. Sir Richard furprifed him with a dedication of this play, and acquainted the public, that he was indebted to him for fome of the moll excellent ftrokes in the performance. The mar¬ quis of Wharton, being appointed lord lieutenant of Ireland in 1.709, took Mr Addifon with him as his. fecretary. Her majefty alfo made him keeper of the records of Ireland, and, as a farther mark of her fa¬ vour, confiderably augmented the falary annexed to that place. Whilft he was in this kingdom, the Tat- ler was lirft publiihed ; and he difcovered his friend Sir Richard Steele to*be the author, by an obfervation on Virgil, which he had communicated to him. He afterwards aflifted confiderably in carrying on this pa¬ per, which the author acknowledges. The Tatler be¬ ing laid down, the Spectator was fet on foot, and Mr Addifon furnifhed great part of the moft admired pa¬ pers. The Spectator made its firft appearance in March 171 (, and was brought to a conclufion in September 1712; His celebrated Cato appeared in 1715. He form¬ ed the defign of a tragedy upon this fubjedt when he was very young, and wrote it when on his travels: he retouched it in England, without any intention of bringing it on the ftage ; but his friends being per- fuaded it would ferve the caufe of liberty,' he was pre¬ vailed on by their folicitationsj and it was accordingly exhibited on the theatre, with a prologue by Mr Pope, and an epilogue by Dr Garth. It was received with the moft uncommon applaufe, having run thirty-five pights without interruption. The Whigs applauded ADD every line in which- liberty was mentioned, as a fatire on the Tories ; and the Tories echoed every clap, to ftiow that the fatire was unfelt. When it was printed, notice was given- that the Queen would be pleafed if it was dedicated to her; “ but as he had defigned that compliment elfewhere, he found himfelf obliged,” fays- Tickell, “ by his duty on the one hand, and his ho¬ nour on the other, to fend it into the world without any dedication.” It was no lefs efteemed abrpad, ha¬ ving been tranfiated into French, Italian, and German; and it was acted at Leghorn, and feveral other places, with vaft applaufe. The Jefuits of St Omers made a Latin verfion of it, and the ftudents adted it with great magnificence. About this time, another paper called the Guardian was publifhed by Steele, to which Addifon was a prin¬ cipal contributor. It was a continuation of the Spec¬ tator, and was diftinguiftied by the fame elegance and the fame variety; but, in confequence of Steele’s pro- penfity to politics, was abruptly difeontinued in order to write the Engliftiman. The papers of Addifon are marked in the Spectator. by one of the letters in the name of Clio, and in the Guardian by a Hand. Many of thefe papers were written with powers truly comic, with nice diferimi- nation of charadlers, and accurate obfervation of na¬ tural or accidental deviations from propriety : but it was not fuppofed that he had tried a comedy on the ftage, till Steele, after his death, declared him the au¬ thor of “ The Drummer.” This, however, he did not know* to be true by any cogent teftimony: for when Addifon put the play into his, hands, he only, told him it was the work of a gentleman in the com¬ pany ; and when it was received, as is eonfeffed, with* cold' difapprobation, he was probably lefs willing to claim it. Tickell omitted it in his eolleftion ; but the teftimony of Steele, and the total filence cf any other claimant*, has-determined the public to affign it to Ad¬ difon, and it is now printed with his other poetry. Steele carried “ The Drummer” to the playhoufe, and afterwards to the prefs, and fold the copy for 50 gui¬ neas; To Steele’s opinion may be added the proof fupplied by the play itfelf, of which the charafters are fuch as Addifon would have delineated, and the ten¬ dency fuch as Addifon would have promoted. It is faid that Mr Addifon intended to have compo¬ fed an Engiifti dictionary upon the plan of the Italian (Della Crufea) ; but, upon the death of the queen, being appointed fecretary to the lords juft ices, he had not leifure to carry on fuch a work. When the earl of Sunderland was appointed lord lieutenant of Ireland, Mr Addifon was again made fecretary for the affairs of that kingdom ; and, upon the earl’s being removed from the lieutenancy, he was chofen one of the lords of trade. Not long afterwards an attempt was made to revive the Spectator, at a time indeed by no means favour¬ able to literature, when the fneceffitm of a new family to the throne filled the nation with anxiety, difeord, and confufion ; and either the turbulence of the times or the fatiety of the readers put a ftop to the publica¬ tion, after an experiment of 80 numbers, which were afterwards collected into, an eighth volume, perhaps more valuable than any of thofe that went before it : Addifon produced more than a fourth part. [ in I ADD [ it Addiron. In 1715, he began the Freeholder, a political pa r ' per, which was much admired, and proved of great ufe at that juncture. He published alfo, about this time, verfes to Sir Godfrey Kneller upon the king’s pifture, and fome to the princefs of Wales with the tragedy of Cato. Before the arrival of king George he was made fe- cretary to the regency, and was required by his office to fend notice to Hanover that the queen was dead, and that the throne was vacant. To do this would not have been difficult to any man but Addifon, who was fo overwhelmed with the greatnefs of the event, and fo di drafted by choice of expreffion, that the lords, who could not wait for the niceties of criticifm, called Mr Southwell, a clerk in the houfe, and ordered him to difpatch the meffage. Southwell readily told what was neceflary, in the common dyle of bufinefs, and valued himfelf upon having done what was too hard for Addifon. In 1716, he married the countefs dowager of War- *wick, whom he had folicited by a very long and anxi¬ ous courtffiip. He is faid to have fird known her by becoming tutor to her fon. The marriage, if uncon- tradifted report can be credited, made no addition to his happinefs; it neither found them nor made them equal. She always remembered her own rank, and thought herfelf in titled to treat with very little cere¬ mony the tutor of her fon. It is certain that Addifon has left behind him no encouragement for ambitious love. The year after, 1717, he rofe to his highed elevation, being made fecretary of date ; but is repre- fented as having proved unequal to the duties of his place. In the houfe of commons he could not fpeak, and therefore was ufelefs to the defence of the govern¬ ment. In the office he could not idue an order with¬ out lofing his time in qued of fine expreffions. At lad, finding by experience his own inability for public bufinefs, he was forced to folicit his difmiffion, with a penfion of 15001. a-year. Such was the account of thofe who were inclined to detraft from his abilities; but by others his relinquifliment was attributed to de¬ clining health, and the neceffity of recefs and quiet. In his retirement, he applied himfelf to a religious •* Evidences work *, which he had begun long before ; part of of the Xian fcarce finifhed, has been printed in his works. £ ’S1011, He intended alfo to have given an Englilh paraphrafe of fome of David’s pfalms. But his ailments increafed, and cut ffiort his defigns. • He had for fome time been opprefied by an adhmatic diforder, which was now ag¬ gravated by a drppfy, and he prepared to die conform¬ ably to his precepts and profeffions. He fent, as Pope relates, a meffage by the earl of Warwick to, Mr Gay, defiring to fee him : Gay, who had not viiited him for fome time before, obeyed the fummous, and found himfelf received with great kindnefs. The purpofe for which the interview had been folicited was then difco- vered: Addifon told him, that he had injured him ; but that, if he recovered, he would recompenfe him. What the injury was he did not explain, nor did Gay ever know ; but fuppofed that fome preferment defign- ed for him had by Addifon’s intervention been with¬ held.—Another death-bed interview, of a more folemn nature, is recorded: Lord Warwick was a young man of very irregular lifej and perhaps of loofe opinions. Addi- ibn, for whom he did not want relpeft, had very diligent- N0 3. 2 ] ADD ly endeavoured to reclaim him ; but his arguments and expoftulations had no effeft : One experiment, how¬ ever, remained to be tried. When he found his life near its end, he direfted the young lord to be called : and when he defined, with great tendernefs, to hear his laft injunftions, told him, “ I have rent for you that “ you may fee how a Chriltian can die.” What ef¬ feft this awful feene had on the earl’s behaviour is not known : he died himfelf in a ffiort time. Having gi¬ ven direftions to Mr Tickell for the publication of his works, and dedicated them on his death-bed to his friend MrCraggs, he died June 17. 1719, at Holland- houfe, leaving no child but a daughter who is ftill living. Addifon’s courfe of life before his marriage has been detailed by Pope. Pie had in the houfe with him Budgell, and perhaps Philips, His chief companions were Steele, Budgell, Philips, Carey, Davenant, and Colonel Brett. With one or other of thefe he always breakfafted. He ftudied all morning 5 then dined at a tavern, and went afterwards to Button’s. From the coffeehoufe he went again to the tavern, where he often fat late, and drank too much wine. Dr Johnfon, in delineating the charafter of Addi¬ fon, obferves with Tickell, that he employed wit on the fide of virtue and religion. He not only made the proper ufe of wit himfelf, but taught it to others; and from his time it has been generally fubfervient to the caufe of reafon and truth. He has diffipated the prejudice that had long connefted gaiety with vice, and eafinefs of manners with laxity of principles. He has rcltored virtue to its dignity, and taught innocence not to be alhamed. This is an elevation of literary charafter, “ above all Greek, above all Roman fame.” No greater felicity can genius attain than that of ha¬ ving purified intelleftual pleafure, feparated mirth from indecency, and wit from licentioufnefs; of having taught a fucceffion of writers to bring elegance and gaiety to the aid of goodnefs ; and, to ufe expreffions yet more awful, of having “ turned many to righte- “ oufnefs.” As a deferiber of life and manners, he mull be allowed to ftand perhaps the firft of the firll rank. His humour, which, as Steele-obferves, is pe¬ culiar to himfelf, is fo happily diffufed as to give the grace of novelty to domellic feenes and daily occur¬ rences. He never “ outfteps the modelly of nature,” nor raifes merriment or wonder by the violation of truth. His figures neither divert by diftortion, nor amaze by aggravation. He copies life with fo much fidelity, that he can be hardly faid to invent; yet his exhibitions have an air fo much original, that it is dif¬ ficult to fuppofe them not merely the produft of ima¬ gination. As a teacher of wifdom he may be confi¬ dently followed. Plis religion has nothing in it enthu- fialtic or fuperllitious ; he appears neither weakly cre¬ dulous nor wantonly fceptical; his morality is neither dangeroufly lax nor imprafticably rigid. All the en¬ chantment of fancy and all the cogency of argument are employed to recommend to the reader his real in- tereft, the care of pleafing the Author of his being. Truth is fhown fometimes as the phantom of a vifion, fometimes appears half-veiled in an allegory ; fometimes attrafts regard in the robes of fancy, and fometimes fteps forth in the confidence of reafon. She wears a thoufand drefles, and in all is pleafing. Add! Ton. ADD [ US ] ADD The Do&or, however, has related the following a- necdote, which every admirer of Addifon, every man of feeling, muft be reluctant to believe. “ Steele (fays the Doctor), whofe imprudence of generofity, or va¬ nity of profufion, kept him always incurably neceffi- tous, upon fome preffing exigence, in an evil hour, borrowed an hundred pounds of his friend, probably without much purpofe of repayment; but Addifon, who feems to have had other notions of a hundred pounds, grew impatient of delay, and reclaimed his loan by an execution. Steele felt, with great fenfibi- lity, the obduracy of his creditor ; but with emotions of forrow rather than of anger.” It is much to be wifhed, fays Dr Kippis, that Dr Johnfcn had produ¬ ced his authority for this narration. It is very pofiible, that it may be only a ftory the Doctor had fomewhere heard in converfation, and which is entirely ground- lefs: “ and this I am the rather inclined to believe, as I have been allured, by one of the moft refpeftable characters in the kingdom, that the fail hath no foun¬ dation in truth.” Mr Potter, in a late publication, hath informed us, that he is told by the beft authority, that the ftory is an abfolute falfehood. Mr Tyers, in “ An hiftorical Eflay on Mr Addi¬ fon,” printed, but not publilhed, has mentioned fome fails concerning him, with which we were not before acquainted. Thefe are, That he was laid out for dead as foon as he was born : that, when he addrefled his rerfes on the Englilh poets to Henry Sacheverell, he courted that gentleman’s filter : that, whenever Ja¬ cob Tonfon came to him for the Spectator, Bayle’s French Hiftorical and Critical Dictionary lay always open before him : that, upon his return to England, after his travels, he difcharged fome old debts he had contracted at Oxford, with the generofity of good intereft : that he was put into plentiful circumftances by the death of a brother in the Eaft Indies : that, having received encouragement from a married lady, of whom he had been formerly enamoured, he had the integrity to refill the temptation : that he refufed a gratification of a three hundred pounds bank-note, and afterwards of a diamond-ring of the fame value, from a Major Dunbar, whom he had endeavoured to ferve in Ireland by his intereft with lord Sunderland : and that his daughter by lady Warwick is ftill alive and unmarried, refiding at Bilton near Rugby, and pofleffing an income of more than twelve hundred a-year. The following letter, which probably relates to the cafe of Major Dunbar, reflects great honour on Mr Addifon’s integrity. “ June 26. 1715. Sir, I find there is a very ftrong oppofition formed againft you ; but I lhall wait on my lord lieutenant this morning, and lay your cafe before him as advantageoully as I can, if he is not engaged in other company. I am afraid what you fay of his grace does not portend you any good. And now, Sir, believe me, when I allure you I never did, nor ever will, on any pretence what- foever, take more than the Hated and cuftomary fees of my office. I might keep the contrary practice concealed from the world, were I capable of it, but I could not from myfelf; and I hope I lhall always fear the reproaches of my own heart more than thofe of all mankind. In the mean time, if I can ferve a gentleman of merit, and fuch a character as you bear in the world, the fatisfaCtion I meet with on Vol.I. Parti. fuch an occafion is always a fufficient, and the only re- Additamsrt ward to, Sir, your moft obedient, humble fervant, Jt. J. Addison.”—The anecdote which follows was told A“dltlons by the late Dr Birch. Addifon and Mr Temple Stan- . ° ^aCC‘ ■ yan were very intimate. In the familiar converfations which palTed between them, they were accuftomed freely to difpute each other’s opinions. Upon fome occafion, Mr Addifon lent Stanyan five hundred pounds. After this, Mr Stanyan behaved with a timid referve, deference, and refpeCt; not converfing with the fame freedom as formerly, or canvaffing his friend’s fenti- ments. This gave great uneafinefs to Mr Addifon. One day they happened to fall upon a fubjeCt, on which Mr Stanyan had always been ufed ftrenuoully to oppofe his opinion. But, even upon this occafion, he gave way to what his friend advanced, without interpofing his own view of the matter. This hurt Mr Addifon fo much, that he faid to Mr Stanyan, “ Either con¬ tradict me, or pay me the money.” In Tickell’s edition of Mr Addifon’s works there are feveral pieces hitherto unmentioned, viz. The Dif- fertation on Medals ; which, though not publilhed till after his death, yet he had collected the materials, and began to put them in order, at Vienna, in 1702. A pamphlet, intitled, The prefent State of the War, and the Neceffity of an Augmentation, confidered. The late Trial and Conviction of Count Tariff. The Whig Examiner came out on the 14th of September 1716: there were five of thefe papers attributed to Mr Addifon, and they are the fevereft pieces he ever wrote. He is faid alfo to have been the author of a performance intitled Dijfertatio de inftgnioribus Roma- norum Poetis, and of a Difcourfe on Ancient and Mo¬ dern Learning. ADDITAMENT, fomething added to another. Thus phyficians call the ingredients added to a medi¬ cine already compounded, additaments. ADDITION, is the joining together or uniting two or more things, or augmenting a thing by the ac- ceffion of others thereto. Addition, in Arithmetic, Algebra, &c. See thefe articles. Addition, in mufic, a dot marked on the right fide of a note, fignifying that it is to be founded or length¬ ened half as much more as it would have been without fuch mark. _ Addition, in law, is that name or title which is given to a man over and above his proper name and furname, to Ihow of what eftate, degree, or myftery he is ; and of what town, village, or country. Additions of EJbate, or Quality, are, Yeoman, Gentle¬ man, Efquire, and fuch like. Additions of Degree, are thofe we call names of dignity; as Knight, Lord, Earl, Marquis, and Duke. Additions of Myftery, are fuch as forivener, painter, mafon, and the like. Additions of Place, are, of Thorp, of Dale, of Woodftock.—Where a man hath houfehold in two places, he ftiall be faid to dwell in both ; fo that his addition in either may fuffice. Knave was anciently a regular addition. By ftat. 1. Hen. V. cap. 5. it was ordained, that in fuch fuits or aCtions where procefs of outlawry lies, fuch addition fliould be made to the name of the defendant, to ftiow his eftate, myftery, and place where he dwells ; and that the writs not ha- P ving A D E [ n 1 ving fuch additions fhall abate if the defendant take exception thereto ; but not by the office of the court. j The reafon of this ordinance was, that one man might not be troubled by the outlawry of another; but by reafon of the certain addition, every perfon might bear his own burden. Additions, in diddling, a name given to fuch things as are added to the waffi, or liquor, while in a date of fermentation, in order to improve the vinofity of the fpirit, 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 thofe of the bufinefs who fpeak moft intelligently addi¬ tions ; but many confound them with things of a very different nature, under the name of ferjnents. See Distilling. Additions, in heraldry, Tome things added to a coat ©f arms, as marks of honour; and therefore direftly ©ppofite to abatements. Amdng additions we reckon Bordure, Quarter, Canton, Gyp„on, Pile, &c. See thcfe articles. ADDRESS, in a general fenfe, is ufed for ikill and good management, and of late has been adopted from the French. It is ufed alfo in commerce, as fy- nonymous with dire ft ion to a perfon or place. The word is formed of the French verb adrejfer, To direct, any thing to a perfon. ADDUCENT muscles, or Adductors, in ana>- tomy, thofe muffles which pull one part of the body towards another. See Anatomy, Table of the Mufcles. ADEB, in commerce, the name of- a large Egyp¬ tian weight, uffd principally for rice, and confifting of 210 okes, each of three rotolos,.a weight of about two drams lefs than the Englifh pound. But thia is no cer¬ tain weight; for at. Rofttto the adeb is only 150 okes. ADEL,, a kingdom'on the eaftern eoaft of Africa, which reaches as far as the ftraits of Babelmandel, which unite the Red Sea to the fea of Arabia. This country produces corn, and feeds a great number of cattle. The inhabitants carry on a trade in gold, fil- ver, ivory, oil, frankincenfe, a fort of pepper, and other merchandifes of Arabia and the Indies. The king was formerly a vaffal to the grand negus of Abyffinia : but being Mahometans, and the Abyffmians a fort of Chri- ftians,, they could not agree ; and in 1535 came to an open rupture, when the Adelines threw off the yoke, feeking proteftion from the Grand Signior. The prin¬ cipal places are, Adda, feated in the centre of the country, and is the town where the king refides : Zeila, near the Arabian Sea, is a rich town, and has a good trade : Barbora, near the fea-coaft, is an ancient trading town. It rains very feldom in this country. ADELIA, a genus of the monadelphia order, be¬ longing to the dicecia elafs of plants ; the charafters of which are : The mask calyx is a perianthium one¬ leaved, three-parted ; the florets fublanced and con¬ cave : No corolla : The famina confi'ft of many capil¬ lary filaments the length of the calyx, conjoined at the bafe in a cylinder ; the antherae are iroundifli. The female calyx is a five-leaved perianthium ; the leaflets fublanced, concave, perfiftent: No corolla : The pi ft il¬ ium has a roundilh germen ; the ftyli are three, Ihort, and divaricated ; the ftigmata lacerated : The perian¬ thium is a three-grained, roundifli, three-celled capfule : The feeds are folitary and roundilh. In the natural 4 ] A D E method, this genus belongs to the 38th order, Tricocca?. Of this genus there are three fpecies; the bernardta, the ricinella, and acidoton, for which we have no pro¬ per names in Englifli. They are natives of Jamaica, and are akin to the ricinus or croton, and may be pro¬ pagated in hot-beds from feeds procured from Jamaica.. ADELME, or Aldhelm, fon to Kenred, nephew to Ina king of the Weft-Saxons; after having been educated abroad, was abbot of Malmfbury 30 years. He was the firft EngHfliman who wrote in Latin, the firft who brought poetry into England,. and the firit bifliop of Sherburn. Fie lived in.great eileem till his death, which happened in 709.. He was canonized, and many miracles wrere told of him. He is mention¬ ed with great honour by Camden and Bayle, and his. life was written by William of Malmibury. ADELPHIANI, in church-hiftory, a left of an¬ cient heretics, who faffed always on Sundays. ADELSCALC, in ancient cuftoms, denotes a fer- vant of the king. The word is alfo written adclfcalchcy and adelfcalcm. It is compounded of the German am!, or edcl, “ noble,” and fcalc, “ fervant.” Among the Bavarians, adelfcatcs appear to have been the fame with royal thanes among the Saxons, and thofe called mini- fri regis in ancient charters. - ADEMPTION, in the civil law, implies the re¬ vocation of a grant, donation, or the like. ADEN, formerly a rich and confiderable town of Arabia the Happy. It is feated by the fea-fide, a little eaftward of the ftraits of Babelmandel. ADENANTHERA, bastard flower-fence, a genus of the monogynia order, belonging to the de- candria clafs of plants. In the natural method, it belongs to the 33J order, Lomentacea. The cha¬ rafters are : The calyx is a perianthium confifting of one very fmall five-toothed leaf. The corolla- corr- fifts of five bell-lhaped lanceolate feffile petals, convex within and concave under. The famina have ten ereft Tubulated filaments fhorter than the corolla ; the anthe- ne are roundifli, incumbent, bearing a globular gland on the exterior top. The pif ilium has a long gibbous ger¬ men ; the ftylus fubulated the length of the ftamina; the ftigma Ample. The pericarpiu?n is a long com- preffed membranous legumen. The feeds are very nu¬ merous, roundifli, and remote. Only one. fpecies of this plant is known in Britain 1 but there is a variety, with ftarlet feeds ; which, how¬ ever, is rare, and grows very flow^y. It is a native of India, and riffs to a confiderable height. It is as large as the tamarind tree ; fpreads itsbranches wide on every fide, and makes a fine ftiade; for which reafon, it is frequently planted by the inhabitants in their gardens or near their habitations. The leaves of this tree are doubly winged, the flowers of a* yellow, colour, and difpofed in a Jong bunch. Theft are fucceeded by long twiffed membranaceous pods, inclofing feveral hard compreffed feeds, of a beautiful ftavlet, or fhining black,, colour. This plant muff be railed in a hot-bed, and kept during winter in a ftove. ADENBURG, or Aldenburg, a town of Weft,- phalia, and in the duchy of Burg, fubjeft* to the Elec¬ tor Palatine.

ADFILIATION, a Gothic cuftom, whereby the children of a former marriage are put upon the fame footing with thofe of the fecond. This is alfo called unto prolium, and dill retained in fome parts of Ger¬ many. AD FINES (Antonine), a town of Swifferland, fuppofed to be the modern Pfin, in the north of the diftrifl of Turgow, on the rivulet Thur, not far from the borders of Suabia, about half-way between Con* ffance and Frauenfield. So called, becaufe when Ce- cinna, general of the emperor Vkellius, with the auxi¬ liary Rhetians, defeated the Helvetii, the former ex¬ tended their borders thus far, their territory ending here 5 and, in time of the Romans, it was the lad town in this quarter, and of fome repute. ADHA, a fedival which the Mahometans celebrate on the 1 oth day of the month Dhoulkegiat, which is the 12th and lad of their year. This month being par¬ ticularly dedined for the ceremonies which the pilgrims obferve at Mecca, it takes its name from thence, for the word fignifies the month of Pilgrimage On that day they facrifice with great folemnity, at Mecca, and no wdiere elfe, a (beep, which is called by the fame name as the fedival itfelf. The Turks commonly call this fedival the Great Beiram, to didinguidi it from the leffer, which ends their fad, and which the Chri- dians of the Levant call the Eafter of the Turks. The Mahometans celebrate this fedival, out of the city of Mecca, in a neighbouring valley ; and fometimes they facrifice there a camel. See Bairam. ADHATODA, in botany.

The fructifications are collected in oval fpots under the refiedted tops of the fronds. Species. Of this genus botanical writers enumerate fifteen fpecies ; the mod remarkable are the following^' i. The capillus veneris, or true maiden-hair, is a na- tive of the fouthern parts of France, from whence it is brought to Britain ; though it is likewife faid to grow plentifully in Cornwall, and the Trichomanes has been almod univerfally fubdituted for it. 2. The pe- datum, or American maiden-hair, is a native of Ca¬ nada ; and grows in fuch quantities, that the French fend it from thence in package for other goods, and the apothecaries of Paris ufe it for maiden-hair in the com- pofitions wherein that is ordered. 3. The trapezi- forme, or black American maylen-hair, is a native of Jamaica; and has filming black dalks, and leaves of an odd fiiape, which make an agreeable variety among other plants, fo is fometimes cultivated in gardens. Culture. The fird fpecies grows naturally out of the joints of walls, and fiffures of rocks. It ought, therefore to be planted in pots filled with gravel and lime-rubbifh ; wrhere it will thrive much better than in good earth. It mud alfo be flickered under a frame during the winter.—-The fecond is to be treated in the fame manner ; but the third will not thrive in Bri¬ tain, unlefs kept in a dove during the winter. Properties. The true maiden-hair has been greatly celebrated in diforders of the bread proceeding from a thinnefs and acrimony of the juices ; and likewife for opening obdruftions of the vifeera, and promoting the expectoration of tough phlegm. But modern practice pays little regard to it; the afplenium trichomanes, or Englifli maiden-hair, fupplying its place. See Asple- nium, ADIAPHORISTS, in church-hidory, a name im¬ porting lukewarmnefs, given, in the 16th century, to the moderate Lutherans, who embraced the opinions of Melanfthon, whofe difpofition was vadly more paci¬ fic than that of Luther.

ADIT, in a general fenfe, the paffage to, or entrance ©f, any thing. jIdit of a Mine, the hole, or aperture, whereby it is entered and dug, and by which the water and ores are carried away. The term amounts to the fame with funiculus or drift, and is diflinguifhed from air-Jhaft. The adit is ufually made on the fide of a hill, towards the bottom thereof, about four, five, or fix feet high, and eight wide, in form of an arch ; fometimes cut in the rock, and fometimes fupported with timber, fo con- dufted as that the foie or bottom of the adit may an- fwer to the bottom of the fliaft, only fomewhat lower, that the water may have a fufficient current to pafs away without the ufe of the pump. Damps and the impurity of the air are the great impediments againft driving adits above 20 or 30 fathoms, by reafon of the necefiity, in this cafe, of letting down air-fhafts from the day to meet the adit, which are often very expen- five, both on account of the great depth of mines, and the hardnefs of the mineral ftrata to be cut through. The beft remedy againft this is that praftifed in the coal-mines near Liege, where they work their adits without air-lhafts: the manner of which is deferibed by Sir Robert Moray. Vid. Phil. Tranf. N° 5. Adit of a Mine is fometimes ufed for the air-lhaft itfelf, being a hole driven perpendicularly from the fur- face of the earth into fame part of a mine, to give en¬ trance to the air. To draw off the ftanding water in winter, in deep mines, they drive up an adit, or air- firaft, upon which the air difengages itfelf from the water, when it begins to run with fuch violence as pro¬ duces a noife equal to the burfting of a cannon, dallies every thing in the way againft the fides of the mine, and loofens the very rocks at a diftance. Ibid. N° 26. ADJUDICATION, implies the aft of adjudging, ©r determining, a caufe in favour of fome perfon. Adjudication, in Scots law, the name of that ac¬ tion by which a creditor attaches the heritable eftate of his debtor, or his debtor’s heir, in order to appro¬ priate it to himfelf, either in payment or fecurity of his debt; or that aftion by which the holder of an heri AJjunJt table right, labouring under any defeft in point of form, . fl . may fupply that defeft. _ _ ADJUNCT, among philofophers,fignifies fomething added to another, without being any neceffary part of it. Thus water abforbed by cloth or a fponge, is an adjunft, but no neceffary part of either of thefe fub- ftances. Adjunct, in metaphyfics, fome quality belonging to either the body or mind, whether natural or acqui¬ red. Thus thinking is an adjunft of the mind, and growth an adjunft of the body. Adjunct, in mufic, a word which is employed to denominate the conneftion or relation between the prin¬ cipal mode and the modes of its two-fifths, which, from the intervals that conftitute the relation between them and it, are called its adjuncts. Adjunct is alfo ufed to fignify a colleague, or fome perfon affociated with another as an affiftant. Adjunct Gods, or Adjuncts of the Gods, among the Romans, were a kind of inferior deities, added as affiftants to the principal ones, to eafe them in their func¬ tions. Thus, to Mars was adjoined Bellona and Ne- mefis; to Neptune, Salacia ; to Vulcan, the Cabiri} to the Good Genius, the Lares; to the Evil, the Le- mures, &c. Adjuncts, in rhetoric and grammar, fignify certain words or things added to others, to amplify or augment the force of the difeourfe. Adjuncts, orAnjoiNTS, in the royal academy of fciences at Paris, denote a clafs of members, attached to the purfuit of particular fciences. The clafs of Ad¬ juncts was created in 1716, in lieu of the Eleves: they are twelve in number ; two for geometry, two for me¬ chanics, two for aftronomy, two for anatomy, two for chemiftry, and two for botany. The Eleves not ta¬ ken into this eftablifhment were admitted on the foot of fupernumerary Adjuncts. ADJUTANT, in the military art, is an officer whofe bufinefs it is to affift the major. Each battalion of foot and regiment of horfe has an adjutant, who re¬ ceives the orders every night from the brigade-major; which, after carrying them to the colonel, he delivers out to the ferjeants. When detachments are to be made, he gives the number to be furnifhed by each company or troop, and affigns the hour and place of rendezvous. He alfo places the guards; receives, and diftributes the ammunition to the companies, &c.; and, by the major’s orders, regulates the prices of bread, beer, and other provifions. The word is fometimes ufed by the French for an aid-du-camp. AojuTANTS-general, among the jefuits, a feleft number of fathers, who refided with the general of the order, each of whom had a province or country affigned him, asEngland, Holland, &c.andtheir bufinefs was to inform the father-general of ftate-occurrences in fuch countries. To this end they had their correfpon- dents delegated, emiffaries, vifitors, regents, provin¬ cials, &c. ADJUTORIUM, a term ufed by phyficians for any medicine in a prefeription but the capital one. ADLE-eggs, fuch as have not received an impreg¬ nation from the femen of the cock. ADLEGATION, in the public law of the German empire, a right claimed by the ftates of the empire of adjoin*- ADM [ i Adlocutlen adjoining plenipotentiaries, in public treaties and nego- II. . ciations, to thofe of the emperor, for the tranfafting of Station" matters relate to the empire in general. In t t, “ ' which fenfe adlegation differs from legation, which is the right of fending ambaffadors on a perfon’s own ac¬ count.—Several princes and ftates of the empire enjoy the right of legation, who have not that of adlegation, and vice verfa. The bifhops, for inftance, have the right of adlegation in the treaties which concern the common intereft, but no right of legation for their own private affairs. The like had the duke of Mantua.— The emperor allows the princes of Germany the privi¬ lege of legation, but difputes that of adlegation. They challenge it as belonging to them jure regni, which they enjoy in common with the emperor himfelf. ADLOCUTION, Adlocutio, in antiquity, is chiefly underftood of fpeeches made by Roman gene¬ rals to their armies, to encourage them before a battle. We frequently find thefe adlocutions expreffed on me¬ dals by the abbreviature Adlocut. Coh.—The ge¬ neral is fometimes reprefented as feated on a tribunal, often on a bank or mount of turf, with the cohorts ranged orderly round him, in vianipuli and turmce. The ufual formula in adlocutions was, Fortis ejfel ae fidut. ADMANUENSES, in ancient law books, denote perfons who fwore by laying their hands on the book. -—In which fenfe, admanuenfes amount to the fame with laymen; and Hand oppofed to clerks, who were forbid to fwear on the book, their word being to be re¬ puted as their oath ; whence they were alfo denomi¬ nated/i.? digni. ADMEASUREMENT, Admensuratio, in law, a writ which lies for the bringing thofe to reafon, or mediocrity, who ufurp more of any thing than their fhare. This writ lies in two cafes ; termed, s1dmf.asurf.ment of Donver, Admenfuratio dotis, where the widow of the deceafed holds more from the heir, or his guardian, on account of her dower, than, of right belongs to her. And, Admeasurement of Pafture, Admenfuratio pafturee; this lies between thofe who have common of paftures appendant to their freehold, or common by vicinage, in cafe any of them furcharge the common with more cattle than they ought. ADMINICLE, a term ufed chiefly in old law¬ books, to imply an aid, help, affiftance, or fupport. The word is Latin, adminiculum; and derived from ad¬ minicular, to prop or fupport. Adminicle, in Scots law, fignifies any writing or deed referred to by a party, in an adfion of law, for proving his allegations. ADMINICULATOR, an ancient officer of the church, whofe bufinefs it was to attend to and defend the caufe of the widows, orphans, and others deftitute of help. ADMINISTRATION, in general, the govern¬ ment, direftion, or management of affairs, and parti¬ cularly the exercife of diftributive juftice ; among ec- clefiaftics, it is often ufed to exprefs the giving or dif- penfing the facraments, &c. Administration, is alfo the name given by the Spaniards in Peru to the ftaple magazine, or warehoufe, eftabliflied at Callao, a fmall town on the S. Sea, which is the port of Lima, the capital of that part of South .America, and particularly of Peru. The foreign /hips, 17 ] ADM which have leave to trade along that coall, are obliged Admini- to unload here, paying 13 per cent, of the price they ^ratof fell for, if the cargo be entire, and even 16 per cent. Admiral, if other-wife; befides which, they pay 3 per 1000, duty, for confulfliip and fome other fmall royal rights and claims. ADMINISTRATOR, in law, he to whom the or¬ dinary commits the adminiftration of the goods of a perfon deceafod, in default of an executor. — An action lies for, or againft an adminiftrator, as for, or againlt an executor; and he fiiall be accountable to the value. of the goods of the deceafed, and no farther:—unlefs? there be wafte, or other abufe chargeable on him. If the adminiftrator die, his executors are not adminiftra- tors; but the court is to grant a new adminiftration, — If a ftranger, who is neither adminiftrator nor exe¬ cutor, take the goods of the deceafed, and adminifter, he fhall be charged, and fued as an executor, not as an adminiftrator. The origin of adminiftrators is derived from the civil law. Their eftabliftiment in England is owing to a ftatute made in the 31ft year of Edw. III.- Till "then, no office of this kind was known befide that of executor: in cafe of a want of which, the ordinary had the difpofal of goods of perfons inteftate, &c. Administrator, in Scots law, a perfon legally im- powered to aft for another whom the law prefumes in¬ capable of afting for himfelf. Thus tutors or curatora are fometimes ftyled adminiflraiors in lanu to pupils, minors, or fatuous perfons. But more generally the term is ufed to imply that power which is conferred by the law upon a father over the perfons and eftates of his children during their minority. See Law, N°clxi. Administrator, is fometimes ufed for the prefi- dent of a province; for a perfon appointed to receive, manage, and diftribute, the revenues of an hofpital or religious houfe ; for a prince who enjoys the revenues of a fecularized bilhopric; and for the regent of a king¬ dom during a minority of the prince, or a vacancy of the throne. ADMIRABILIS sal, the fame with Glauber’s fait. See Chemistry, n° 124. ADMIRAL, a great officer or magiftrate, who has the government of a navy, and the hearing of all ma¬ ritime caufes. Authors are divided with regard to the origin and denomination of this important officer, whom we find eftabliflied in moft kingdoms that border on the fea. But the moft; probable opinion is that of Sir Henry Spelman, who thinks, that both the name and dignity were derived from the Saracens, and, by reafon of the holy wars, brought amongft us; for admiral, in the Arabian language, fignifies a prince, or chief ruler, and was the ordinary title of the governors of cities, provinces, &c. and therefore they called the com¬ mander of the navy by that name, as a name of dignity and honour. And indeed there are no inftances of admirals in this part of Europe before the year 1284, when Philip of France, who had attended St Lewis in the wars againft the Saracens, created an admiral. Du Cange affures us, that the Sicilians were the firft, and the Genoefe 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 E- mir, a general name for every commanding officer. As for the exaft time when the word was introduced among us, it is uncertain ; fome think if was in the reign of" Edward Si. ADM t i: Admiral. Edward I. Sir Henry Spelman is of opinion that it ’ ^ was firft ufed in the reign of Henry III. becaufe nei¬ ther the laws of Oleron made in 1266, nor Bracton, who wrote about that time, make any mention of it; and that the term admiral was not ufed in a charter in the eighth of Henry III. wherein he granted this of¬ fice to Richard de Lacey, by thefe words Mat itimom Anglia; but in the 56th year of the fame reign, not only the hifiorians, but the charters themfelves, very fre¬ quently ufe the word admiral. Anciently there were generally three or four admi¬ rals appointed in the Englifh feas, all of them holding the office durante bene placito; and each of them having particular limits under their charge and government; as admirals of the fleet of {hips, from the mouth of the Thames northward, fouthward, or weftward. Befides thefe, there were admirals of the Cinque Ports, as in the reign of Edward III. When one William Latimer was llyled admiralis quinque portuum; and we fometimes iind that one perfon has been admiral of the fleets to the fouthward, northward, and weftward : but the title of a lmiralis Anglia was not frequent till the reign of Henry IV. when the king’s brother had that title gi¬ ven him, which in all commiffions afterwards was grant¬ ed to the fucceeding admirals. It may be obferved, that there was a title above that of admiral of England, which was, locum~tenens regis fupsr mare, the king’s lieu¬ tenant-general of the fea ; this title we find mentioned in the reign of Richard II.—Before the ufe of the word admiral was known, the title of cuftos.maris was made ufe of. Lord High Admiral of England, in fome ancient re¬ cords called capitanus maritimarum, an officer of great antiquity and truft, as appears by the laws of Oleron, fo denominated from the place they were made at by Richard I. The firft title of Adtniral of England, ex- prefsly conferred upon a fubjeft, was given by patent of Richardll. to Richard Fitz-Allen, junr. earl of Arun¬ del and Surrey; for thofe who before enjoyed this of¬ fice were Amply termed admirals, though their jurif- diction feems as large, efpecially in the reign of Edward III. when the court of admiralty was firft erected. This great officer has the management of all mari¬ time affairs, and the government of the royal navy, with power of decifion in all maritime cafes both civil and criminal.: he judges of all things done upon or beyond the fea, in any part of the world ; upon the fea-coafts, in all ports and havens, and upon all rivers below the firft bridge from the fea. By him, vice-admirals, rear- admirals, and all fea-captains, are commiffioned j all de¬ puties for particular coafts, and coroners to view dead bodies found on the fea-coafts, or at fea: he alfo ap¬ points the judges for his court of admiralty, and may imprifon, releafe, &c. All ports and havens are infra corpus ccmitatus, and the admiral hath no jurifdittion of any thing done in them. Between high and low wa¬ ter-mark, the common-law and the high-admiral have .jurifdidtion by turns, one upon the water, and the other .upon the land. The lord-admiral has power, not only over the fea- men ferving in his (hips of war, but over all other fea- men, to arreft them for the fervice of the ftate ; and, If any of them run away, without leave of the admiral, he hath power to make a record thereof, and certi¬ fy the fame to the ftveriffs, mayors, bailiffs, &c. who fhall caufe them to be apprehended and imprifoned. 8 ] ADM To the lord high-admiral belong all penalties and Admiral, amercements of all tranfgreffions at fea, on the fea-fnore, Admiralty. in ports and havens, and all rivers below the firft bridge W from the fea; the goods of pirates and felons condemn¬ ed or enflaved', fea-wrecks, goods floating on the fea, or caft on the fhore (not granted to lords of manors adjoining to the fea), and a fhare of lawful prizes; alfo all great fifties, commonly called royal fijbes, except whales and fturgeons: to which add, afalary of 7000/* a-year. In fhort, this is fo great -en office, in point of truft, honour, and profit, that it has been ufually given to princes of the blood, or the moft eminent perfons among the nobility. We have had no high admiral for fome years; the office being put in commiffion, or under the adminiftration of the lords commifiloners of the admi¬ ralty, who by ftatute have the fame power and autho¬ rity as the lord high admiral. Lord High Admiral of Scotland, one of the great of¬ ficers of the crown, and fupreme judge in all maritime cafes within that part of Britain. See Law, Part III. N° clvii. 15. Admiral, alfo implies the commander in chief of any fingle fleet or fquadron ; or, in general, any flag- officer whatever. The commander of a fleet carries his flag at the main-top-maft head. Vice Admiral, is the commander of the fecond fqua¬ dron, and carries his flag at the fore-top-maft head. Rear Admiral, is the commander of the. third fqua¬ dron, and carries his flag at the mizen-top-mafthead. Vice Admiral, is alfo an officer appointed by the lords commiffioners of the admiralty. There are feveral of thefe officers eftabliftied in different parts of Great Britain, with judges and martinis under them, for ex¬ ecuting jurifdiction within their refpeftive limits. Their decrees, however, are not final, an appeal lying to the court of admiralty in London. Admiral is alfo an appellation given to the moft confiderable fiiip of a fleet of merchant-men, or of the veflels employed in the cqd-fiftiery of Newfoundland. This laft has the privilege of choofing what place he pleafes on the fhore to dry his fifh; gives proper orders, and appoints the fifliing-places to thofe who come after him; and as long as the fiftiing-feafon continues, he carries a flag on his maiii-maft. Admiral, in zoology, the Englifh name of a fpe- cies of the voluta, a fliell-lifh belonging to the order of vermes teftacea. See Voluta. ADMIRALTY properly fignifies the office of lord high-admiral, whether difcharged by one fingle per¬ fon, or by joint commiffioners called lords of the admi¬ ralty. a Court of Admiralty, is a fovereign court, held by the lord high-admiral, or lords of the admiralty, where cognizance is taken in all maritime affairs, whether ci¬ vil or criminal.—All crimes committed on the high- feas, or on great rivers below the firft bridge next the fea, are cognizable in this court only, and bJfcre which they muff be tried by judge and jury. But in civil ca¬ fes the mode is different, the decifions being all made according to the civil law/ From the fentences of the admiralty-judge an appeal always lay, in ordinary courfe, to the king in chancery, as may be colledted from ffatute 25 Hen. VIII. c. 19. which diredfs the appeal from the archbiftiop’s courts to be determined by perfons named in the king’s commiffion, “ like as in “ cafe A D N [ i Admiralty « c?.fe of appeal from the admiral-court.” But this is Adnata ai^0 exprefsly declared by ftatute 8 Eliz. c. 5. which ■ , enafts, that upon an appeal made to the chancery, the fentence definitive of the delegates appointed by com- miffion lhall be final. Appeals from the vice-admiralty courts in Ameri- ■ ca, and our other plantations and fettlements, may be brought before the courts of admiralty in England, as being a branch of the admiral’s jurifdiftion, tho’ they may alfo be.brought before the king in council. But in cafe of prize veffela, taken in time of war, in any part of the world, and condemned in any courts of ad¬ miralty or vice-admiralty as lawful prize, the appeal lies to certain commiffioners of appeals confiding chiefly of the privy council, and not to judges delegates. And this by virtue of divers treaties with foreign nations, by which particular courts are eftablifhed in all the maritime countries of Europe for the decifion of this queftion, Whether lawful prize or not ?_ for this being a quellion between fubjetts of different dates, it belongs entirely to the law of nations, and not to the municipal laws of either country, to deter¬ mine it. Court of Admiralty in Scotland. See Law, Part III. N’ clvii. 15. Admiralty Iflands, lie in about 2° 18' S. Lat. and 146 44'E. Long. There are between 20 and 30 illands faid to be fcattered about here, one of which alone would make a large kingdom. Captain Carteret, who fird difcovered them, was prevented touching at them, although their appearance was very inviting, on. account of the condition of his fhip, and of his being entirely unprovided with the articles of barter which fuit an Indian trade. He defcribes them as clothed with a beautiful verdure of woods, lofty and luxuriant, interfperfed with fpots that have been cleared for plan¬ tations, groves of cocoa nut-trees, and houfes of the na¬ tives, who feem to be very numerous. Thelargedof thefe iflands is 18 leagues long in the direftion of ead and wed. The difcoverer thinks it highly probable that thefe iflands produce feveral valuable articles of trade, particularly fpices, as they lie in the fame, climate and latitude as the Moluccas. ADMONITION, in ecclefiadical affairs, a part of difcipline much ufed in the ancient church. It was the fird act, or dep, towards the puuifhment or expulfion of delinquents. In cafe of private offences, it was per¬ formed according to the evangelical rule, privately: in cafe of public offence, openly,, before the church. If. either of thofe fufficed for the recovery of the fallen perfon, all further proceedings in the way of cenfui-e ceafed: if they did not, recourfe was had to excom¬ munication. Admonitio Fuflium, among the Romans, a military punifliment, not unlike our whipping, only it was per¬ formed with vine-branches. ADMORTIZATION, in the feudal cudoms, the reduction ox the property of lands or tenements to mortmain. See Mortmain. ADNATA, in anatomy, one of the coats of the eye, which is alfo called conjunfiiva and albuginea. Adnata, is alfo ufed for any hair, wool, or the like, which grows upon animals or vegetables. Adnata, or Aclnafcentia, among gardeners, denote thofe off-fets, which, by a new germination under the earth, proceed from1 the lily, narciffus, hyacinth, and. 19 ] A D N other flowers, and afterwards grow to true roots. The Adnoun French call them cayeux, “ ftalks.” Adon’ai ADNOUN, is ufed by fome grammarians to ex- prefs what we more ufually call an Adjeftive. The wrord is formed by way of analogy to adverb ; in re¬ gard adjeftives have much the fame office and relation to nouns that adverbs have to verbs. Biihop Wilkins- ufes the word adname in another fenfe,, viz. for what- we otherwife call a prepofition. ADOLESCENCE, the {late of growing youth or that period of a perfon’s age commencing from his infancy, and terminating at his full llature or man¬ hood. The word is formed of the Latin adolefcere.. to grow.—The Hate of adolefcence lafts fo long as the fibres continue to grow, either in magnitude or firmnefs. The fibres being arrived at the degree of firmnefs and tenfion fufficient to fuftain the parts, no- longer yield or give way to the efforts of the nutri¬ tious matter to extend them ; fo that their farther ac¬ cretion is flopped, from the very law of their nutrition. Adolefcence is commonly computed to be between 15 and 25, or even 30 years of age; though in different conftitutions its terms are very different.—The Ro¬ mans ufually reckoned it from 12 to 25 in boys; and to 21 in girls, &c. And yet, among their writers, jli¬ ven is and adolefcens are frequently ufed indifferently for any perfon under 45 years. ADOLLAM, or Odollam (anc. geog.), a town, in the tribe of Judah, to the eafl of Eleutheropolis. David is faid to have hid himfelf in a cave near this, town, (Bible.) ADON, a populous village in the province of Stuhl- Weiffemberg, belonging to Hungary. It lies in a fruitful country, towards the river Danube. Long. 19. 20. Lat. 47. 30. ADONAI, one of the names of the Supreme Being in the feriptures. The proper meaning of the word is my lords, in the plural number ; as Adoni is my lord, in ■ the fingular. The Jews, who either out of refpefl, or fuperflition, do not pronounce the name of febovahy. read Adonai in the room of it, as often as they meet- with Jehovah in, the Hebrew text. But the ancient Jews were not fo fcrupulous ; nor is there any law which forbids them to pronounce the name of God. Calmet. ADONIA, in antiquity,, folemn fealls in honour of Venus, and in memory of her beloved Adonis. The Adonia were obferved with great folemnity by moft nations; Greeks,Phcenicians, Lycians,.Syrians, Egyp¬ tians, &c. From Syria, they are fuppofed to have l'ch.viii,x4v paffed into India. The prophet Ezekiel* is underffood to fpeak .of them.. They were ilill obferved at Alexan¬ dria in the time of St Cyril; and at Antioch in that of Julian the apoftate, who happened to enter that city during the folemnity, which was taken for an ill omen.- The Adonia lafted two days : on the firlt of which cer¬ tain images of Venus and Adonis were carried, with all the pomp and ceremonies, pradlifed at funerals ; the wo¬ men wept, tore. their hairv.beat their breafts, &c. imi¬ tating the cries and lamentations of Venus-for the death, of her paramour. This kunentation they called The Syrians were not contented with weeping, but gave themfelves difcipline, fhaved their heads, &c. Among^ the Egyptians, the queen herfelf ufed to carry the image of A donis in proceffion. St Cyril mentions an extraordi¬ nary ceremony practifed by the Alexandrians: A letter-> was written to thewomenofBybulus,to inform them that Adonis,, A D N [ 120 ] ADO Adonides, Adonis was found again: this letter was thrown into the , Adorns. (it Was pretended) did not fail punctually to v~" convey it to Bybulus in feven days; upon the receipt of which, the Byblian women ceafed their mourning, fung his praifes, and made rejoicings as if he were raifed to life again : Or rather, according to Meurfius, the two offices of mourning and rejoicing made two diftinft .feafts, which were held at different times of the year, the one fix months after the other ; Adonis being fup- pofed to pafs half the year with Proferpine, and half v/ith Venus.—The Egyptian Adonia are faid to have been held in memory of the death of Ofiris ; by others, of his ficknefs and recovery. Bifhop Patrick dates their origin from the daughter of the firft-born under Mofes. ADONIDES, in botany, a name given to botanifts who deferibed or made catalogues of plants cultivated in any particular place. ADONIS, fon to Cinyras king of Cyprus, the dar¬ ling of the goddefs Venus : being killed by a wild boar in the Idalian woods, he was turned into a flower of a blood-colour, fuppofed to be the Anemone. Venus was inconfolable; and no grief was ever more celebrated than this, molt nations having perpetuated the memory f.SeeMonia of it by a train of anniverfary ceremonies*. Among Shakefpeare’s poems, is a long one on the fubjeCt of Venus’s affeCtion for Adonis. The text of the vulgate in Ezekiel, viii. 14. fays, that this prophet faw women fitting in the temple, and weeping for Adonis : but according to the reading of the Hebrew text, they are faid to weep for Tammuz, or the hidden one. Among the Egyptians, Adonis was adored under the name of Ofiris the hufband of Ills. But he was fometimes called by the name of Ammuz, or Tammuz, the concealed, to denote pro¬ bably his death or burial. The Hebrews, in derifion, call him fometimes the dead, Pfal. cvi. 28. and Lev. xix. 28. becaufe they wept for him, and reprefented him as one dead in his coffin ; and at other times, they call him the image of jealoufy, Ezek. viii. 3. 5. be¬ caufe he was the objeCt of the god Mars’s jealoufy. The Syrians, Phoenicians, and Cyprians called him A- donis, and F. Calmet is of opinion, that the Ammo¬ nites and Moabites gave him the name of Baal-peor. See Baal-peor. Adonis, Adonius, (anc. geog.); a river of Phoe¬ nicia, rifing in mount Lebanon, and falling into the fea, after a north-well courfe, at Bybulus; fa¬ mous in fable, as a beautiful fhepherd youth, Virgil; fon of Cynaras, king of the Cyprians, loved by Venus, llain by a boar, and turned into a river. Theocritus la¬ ments him dead in an idyllion, or rather ode, as did the women yearly, when in flood-time, the river rolled down a red earth, which tinged its waters, deemed to be his wound bleeding afrelh In the Phoenician lan¬ guage Adan fignifies a willow, and Adon lord, with the fame radical letters. Hence i-raior A<5Wf, Salignus, and Kvjif, or Kipij AJaur, for Kvgiic- Adonidis horti, are gardens beautifully arranged, but more adapted for pleafure than profit. Adonis, Birds-eye, or Pheafants-eye; a genus of the polyandria order, belonging, to the polygynia clafs of plants. It is affociated with the Multiftli- quae, or 26th Nat. Order.—The characters are: The calyx is a perianthium, confifting of five obtufe concave leaves, fomewhat coloured, and deciduous. The corolla N° 3. has from five to fifteen oblong petals obtufe and glof- Adomfts fy. The Jlamina confift of very numerous, fhort, fub- A(j0pt;0n> ulated filaments ; the anthene are oblong and infleCled. ■ , * The pijlillum has numerous germina colluded in a head; noftyli; the ftigmata acute and reflected. There is no pericarpium; the receptacle is oblong and fpiked. The feeds are numerous, irregular, angular, gibbous at the bafe, reflected at the top, fomewhat prominent, and awnlefs. Species. The moll remarkable fpecies are the follow¬ ing : 1. The annua, or common adonis, is a native of Kent, where it is found in great plenty in the fields fown with wheat. Its flowers are of a beautiful fcarlet colour, and appear in the beginning of June; the feeds ripen¬ ing in Auguft and September. Great quantities of thefe flowers are fold in London, under the name of Red Morocco. 2. The asftivalis, or annual adonis, with yellow flowers, grows much taller than the firft, has its leaves thinner fetr and of a lighter colour. 3. The vernalis, or perennial adonis, grows naturally on the mountains of Bohemia, Pruffia, and other parts of Germany. It flowers the latter end of March, or be¬ ginning of April; the llalks rife about a foot and a half high ; and when the roots are large, and have flood unremoved for fome years, they will put out a great number of flalks from each root; on the top of each of thefe grows one large yellow flower. 4. The apennina, is a native of Siberia and the Appenines. Culture. The firft two fpecies, being annual, muft be propagated from feeds, which ought to be fown in autumn, foon after they are ripe, or they will be in danger of not growing up that year. They thrive beft in a light foil. The third and fourth fpecies are like- wife to be propagated from feeds, which muft be fown in autumn, or they feldom fucceed. When the plants come up, they muft be carefully kept clear from weeds; and in very dry weather their growth will be promoted by being now and then watered. They fhould remain in the place where they are fown till the fecond year; and be tranfplanted thence in autumn, to the place where they are to remain. ADONISTS, a feCl or party, among Divines and Critics, who maintain, that the Hebrew points ordina¬ rily annexed to the confonants of the word Jehovah, are not the natural points belonging to that word, nor ex- prefs the true pronunciation of it; but are the vowel- points, belonging to the words Adonai and Elohim, ap¬ plied to the confonants of the ineffable name Jehovah ; to warn the readers, that inftead of the word Jehovah, which the Jews were forbid to pronounce, and the true pronunciation of which had been long unknown to them, they are always to read Adonai. They are op- pofed to JehoviJis: of whom the principal are Drufius, Capellus, Buxtorf, Alting, and Reland, who has pu- blifhed a colleftion of their writings on this fubjeft. ADOPTIANI, in church-hiftory, a fe£l of ancient heretics, followers of Felix of Urgel, and Elipand of Toledo, who, towards the end of the eighth century, advanced the notion, that Jefus Chrift, in his human na¬ ture, is the fon of God, not by nature, but by adoption. ADOPTION, an aft by which any one takes ano¬ ther into his family, owns him for his fon, and appoints him for his heir. The cuftom of adoption was very common among the ancient Greeks and Romans; yet it was not prac- 1 tifed. A D O [12 sA<3opt'on. tifed, but for certain caufes expreffed in tbe laws, and " with certain formalities ufual in fuch cafes. It was a fort of imitation of nature, intended for the comfort of thofe who had no children : wherefore he that was to adopt was to have no children of his own, and to be paft the age of getting any ; nor were eunuchs allow¬ ed to adopt, as being under an actual impotency of begetting children ; neither was it lawful for a young man to adopt an elder, becaufe that it would have been contrary to the order of nature ; nay, it was even re¬ quired that the perfon who adopted fliould be eighteen years older than his adopted fon, that there might at lealt appear a probability of his being the natural fa¬ ther. Among the Greeks it was called viothc, filiation. It was allowed to fuch as had no iffue of their own ; ex¬ cepting thofe who were not xup/o< skutuv, their own ma- Jlers, e. g. Haves, women, madmen, infants, or perfons under twenty years of age; who being incapable of making wills, or managing their own eftates, were not allowed to adopt heirs to them. Foreigners being in¬ capable of inheriting at Athens, if any fuch were a- dopted, it was neceffary lirft to make them free of the city. The ceremony of adoption being over, the a- dopted had his name inrolled in the tribe and ward of his new father; for which entry a peculiar time was allotted, viz. the feftival bapytiMa. To prevent rafli and inconfiderate adoptions, the Lacedsemonians had a law, that adoptions fhould be tranfa&ed, or at lead confirm¬ ed, in the prefence of their kings. The children adopt¬ ed were invefted with all the privileges, and obliged to perform all the duties, of natural children ; and being thus provided for in another family, ceafed to have any •tlaim of inheritance, or kindred, in the family which they had left, unlefs they firft renounced their adop¬ tion ; which, by the laws of Solon, they were not al¬ lowed to do, unlefs they had firft begotten children, to bear the name of the perfon who had adopted them : thus providing againft the ruin of families, which would otherwife have been extinguilhed by the defertion of thofe who had been adopted to preferve 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 re¬ lations of the adopter. It fhould feem, that by the Athenian law, a perfon, after having adopted another, was not allowed to marry without permiffion from the magiftrate: in effeft, there are inftances of perfons, who being ill ufed by their adoptive children, petition¬ ed for fuch leave. However this be, it is certain fome men married after they had adopted fons: in which cafe, if they begat legitimate children, their eftates were equally lhared between the begotten and adopted. The Romans had two forms of adoption ; one be¬ fore the pretor ; the other at an affembly of the people, in the times of the commonwealth, and afterwards by a refeript of the emperor. In the former, the natural father addreffed himfelf to the pretor, declaring that he emancipated his fon, refigned all his authority over him, and confented he fhould be tranflated into the fa¬ mily of the adopter. The latter was praclifed, where the party to be adopted was already free j and this was called adrogation. The perfon adopted changed all his names ; affuming the prename, name, and furname, of the perfon who adopted him. Vot.I. Parti. " i ] ADO Befides the formalities preferibed by the Roman law, Adoption., various other methods have taken place ; which have ' y ^ given denominations to different fpecies of adoption, among the Gothic nations, in different ages. As, Adoption by arms, was when a prince made a pre- fent of arms to a perfon, in confideratian of his merit and valour. Thus it was that the king of the Heruli was adopted by Theodoric 5 Athalaric by the emperor Ju- ftinian ; and Cofroes, nephew of the king of Perfia, by the emperor Juftin.—The obligation here laid on the adoptive fon was, to proteft and defend the father from injuries, affronts, See. And hence, according to Selden, the ceremony of dubbing knights took its ori¬ gin as well as name. Adoption by baptifin, is that fpiritual affinity which is contracted by god-fathers and god-children in the ce¬ remony of baptifm. This kind of adoption was intro¬ duced into the Greek church, and came afterwards in- to*ufe among the ancient Franks, as appears by the Capitulars of Charlemagne. In reality, the god-father was fo far confidered as adoptive father, that his god-children were fuppqfed. to be intitled to a ftiare in the inheritance of his eftate. Adoption by hairy, was performed by cutting off the hair of a perfon, and giving it to the adoptive father. It was thus that pope John VIII. adopted Bofon king of Arles ; which, perhaps, is the only inftance in hi- ftory, of adoption, in the order of the ecclefiaftics; a law that profeffes to imitate nature, not daring to give children to thofe in whom it would be thought a crime to beget any. Adoption by matrimony, is the taking the children of a wife or hulband, by a former marriage, into the condition of proper or natural children 5 and admitting them to inherit on the fame footing with thofe of the prefent marriage. This is a pradtice peculiar to the Germans ; among whom, it is more particularly known by the name of einkindfchafl; among, their writers in Latin, by that of unio prolium, or union ofijfues. But the more accurate writers obferve, that this is no adop¬ tion. See Adfiliation. Adoption by tejlament, that performed by appointing a perfon heir by will, on condition of his affuming the name, arms. See. of the adopter. Of which kind we meet with feveral inftances in the Roman hiftory. Among the Turks, the ceremony .of adoption is per¬ formed by obliging the perfon adopted to pafs through the ftiirt of the adopter. Hence, among that people, to adopt, is expreffed by the phrafe, to draw another through my Jhirt. It is faid, that fomething like this haa alfo been obferved among the Hebrews; where the prophet Elijah adopted Elifna for his fon and fucceffor, and communicated to him the gift of prophecy, by let¬ ting fall his cloak or mantle on him. But adoption, properly fo called, does not appear to have been prac- tifed among the ancient Jews: Mohs Jays nothing of it in his laws ; and Jacob’s adoption of his two grand- fons, Ephraim and Manaffeh, is not fo properly an adoption, as a kind of fubftitution, whereby thofe two fons of Jofeph were allotted an equal portion in Ifrael with his own fons. Adoption is alfo ufed, in theology, for a federal an ri~ fiX£d to it *. He. had great wit, and an extenfive me¬ mory. He underllood the fciences perfectly well; but Adrian,. was very jealous of others who excelled in them. He ' c—“J was alio cruel, envious, and lafcivious. Antoninus his fucceffor obtained his apotheofis; and prevented the re- fciflion of his acts, which the fenate once intended. ADRIAN IV. (Pope), the only Engliihman who ever had the honour of fitting in the papal chair. His name was Nicholas Brekefpere; and he was born at Langley, near St Alban’s, in Hertfordlhire. His father having left his family, and taken the habit of the monaitery of St Alban’s, Nicholas was obliged to fubmit to the lowefl: offices in that houfe for daily fup- port. After fome time, he defired to take the habit in that monaftery, but was rejected by the abbot Richard. Upon this he refolved to try his fortune in another coun¬ try, and accordingly went to Paris ; where, though in very poor circumftances, he applied himfelf to his ftudies with great affiduity, and made a wonderful pro¬ ficiency. But having ftill a llrong inclination to a re¬ ligious life, he left Paris, and removed to Provence, where lie became a regular, clerk in the monaftery of St Rufus. He was not immediately allowed to take the habit; but paffed fome time, by way of trial, in re¬ commending himfelf to the monks by a ftrift attention to all their commands. This behaviour, together with ■ the beauty of his perfon, and prudent converfation, rendered him fo acceptable to thofe religious, that af¬ ter fome time they intreated him to take the habit of the canonical order. Here he diftinguilhed himfelf fo much by his learning and ftrift obfervauce of the mo- naftic difcipline, that, upon the death of the abbot, he was chofen fuperior of that houfe ; and we are told that ke rebuilt that convent. Pope- Eugenius III. being apprifed of the great merit of Nicholas, and thinking he might be ferviceable to the church in a higher ftation, created him cardinal-bifnop of Alba in 1-146. In 1148, his Holinefs fent, him legate to Denmark and Norway; where, by his fervent preach¬ ing and diligent inftruCtions, he converted thofe bar¬ barous nations to the Chriftian faith; and erected Up- fal- the town of Newcaftle now Hands; fo that it muft have been above 60 Englifh, and near 70 Roman miles in length. It confifted of four parts: 1. The principal agger, mound of earth, or rampart, on the brink of the ditch. 2. The ditch on the north fide of the rampart. 3. Another rampart on the fouth fide of the principal one, about five paces diftant from it. 4. A large rampart on the north fide of the ditch.—This laft. was pro¬ bably the military way to the line of forts on this work : it was fo to thofe formerly built by Agricola ; and if iti did not ferve the fame purpofe in this, there mull have been no military way attending it.—The fouth ram¬ part might ferve for an inner defence in cafe the enemy fhould beat them from, any part of the principal ram¬ part, or it might be defigned to protect the foldiers from any fudden attack of the provincial Britons.—For many ages, this work hath been in fo ruinous a condition, that it is impoffible to difcover its original dimen- fions with certainty. From: their appearance, it feems probable, that the principal rampart was at ieaft 10 or 12 feet high, and the fouth one not much lefs ; but the north one was confiderably lower. From the dimen- fions of the ditch taken as it paffes through a lime-ftone quarry near Harlow hill, it appears to have been 9 feet deep, and \ 1 wide at the top, but fomewhat narrower at the bottom. The north rampart was about 20 feet , diftant from the ditch. (b) The verfes are thefe : Animula vagula, blandula, Hofpes, comefque corporis,.

ADR [ 126 ] ADR A tin an.- fal into an archiepifcopal fee. When he returned to 1 Rome, he was received by the pope and cardinals with great marks of honour: and Pope Anaftafius, who fucceeded Eugenius, happening to die at this time, Nicholas was unanimoufly chofen to the holy fee, in November 1154, and he took the name of Adrian. When the news of his promotion reached England, King Henry II. fent Robert abbot of St Alban’s, and three biihops, to Rome, to congratulate him on his ele&ion ; upon which occafion Adrian granted very confiderable privileges to the ntonaftery of St Alban’s, particularly an exemption from all epifcopal jurifdic- tion, excepting to the fee of Rome. Adrian, in the beginning of his pontificate, boldly withftood the at¬ tempts of the Roman people tjo recover their ancient liberty under the confuls, and obliged thofe magiftrates to abdicate their authority, and leave the government of the city to the pope. In 1155, he drove the he¬ retic Arnaud of Breffe, and his followers, out of Rome. The fame year he excommunicated William king of Sicily, who ravaged the territories of the church, and abfolved that prince’s fubjefts from their allegiance. About the fame time, Frederic king of the Romans, having entered Italy with a powerful army, Adrian met him near Sutrium, and concluded a peace with him. At this interview, Frederic confented to hold the pope’s ftirrup whilft he mounted on horfeback. After which, his holinefs conducted that prince to Rome, and in St Peter’s church placed the imperial crown on his head, to the great mortification of the Roman people, who affembled in a tumultuous man¬ ner, and killed feveral of the Imperialifts. The next year a reconciliation was brought about between the pope and the Sicilian king, that prince taking an oath to do nothing farther to the prejudice of the church, and Adrian granting him the title of king of the two Si¬ cilies. He built and fortified feveral cattles, and left the papal dominions in a more flourilhing condition than he found them. But notwithftanding all his fuccefs, he was extremely fenfible of the difquietudes attending fo high a ftation ; and declared to his countryman John of Sa- lilbury, that all the former hardlhips of his life were mere amufemeut to the misfortunes of the popedom : that he looked upon St Peter’s chair to be the moft uneafy feat in the world; and that his crown feemed to * Baronius be clapped burning on his head*. He died Septem- Annal.tom ker K jn t^c fourth year and tenth month of his Ei.an.1ij4. pontificate . anq was buried in St Peter’s church, near the tomb of his predecefibr Eugenius. There are ex¬ tant feveral letters, and fome homilies, written by Pope Adrian. ADRIAN, cardinal-prieft, of the title ofStChry- fogonus, was a native of Cornetto in Tufcany. Inno¬ cent VIII. fent him nuncio into Scotland and into France ; and after he had been clerk and treafurer of the apoftolic chamber, pope Alexander VI. whofe fe- cretary he had been, honoured him with the cardinal’s hat. His life was a continued fcene of odd alterations. Fie narrowly efcaped death the day Alexander VI. poi- foned himfelf by miftake. Afterward he drew upon liimfdf the hatred of Julius II. fo that he was obliged to go and hide himfelf in the mountains of Trent. Ha¬ ving been recalled by Leo X. he was fo'ungrateful, that he engaged in a confpiracy againft him. The pope par¬ doned his fault; but the cardinal, not caring to trutt to this, made his efcape, and it could never be known Adrian a 1 exactly what was become of him. He was one of the ,11 ' firft that effectually reformed the Latin ftyle. He ftu- Adna"0Ple;|; J died Cicero with great fuccefs, and made many excel- y lent obfervations on the propriety of the Latin tongue. The treatife he compofed De fermone Latino, is a proof of this. He had begun a Latin tranflation of the Old Teftament. He wrote De vera philofopkia : This trea¬ tife was printed at Cologn 1548. ADRIAN VI. (Pope), was born at Utrecht in 1459. His father was not able to maintain him at fchool, but Jie got a place at Louvain, in a college in which a certain number of fcholars wrere maintained gratis. It is reported that he ufed to read in the night-time by the light of the lamps in the churches or ftreets. He made a confiderable progrefs in all the feienetr ; led an exemplary life ; and there never was a man lefs intriguing and forward than he was. He took his degree of dodfor of divinity at Louvain ; w-as foon after made canon of St Peter’s, and profeffor ,of divinity at Utrecht, and then dean of St Peters and vice-chancellor of the univerfity. • He was obliged to leave an academical life, to be tutor to the archduke Charles. This young prince made no great progrefs under him': however, never wras a tutor more confi- derably rewarded ; for it was by Charles V.’s credit he was railed to the papal throne. Leo X. had given him the cardinal’s hat in 1517. After this pope’s death, feveral cabals in the conclave ended in the eleftion of Adrian, with which the people of Rome were very much difpleafed. He would not change his name, and in every thing he Ihow'ed a great diflike for all of- tentation and fenlual pleafures, though ftich an averfion had been long ago out of date. He was very partial to Charles V. and did not enjoy much tranquillity un.- der the triple crown. He lamented much the wicked morals of the clergy, and wiihed to eftabliih a refor¬ mation of manners among them. He died Sept. 14. 1523* ADRIANI (Joanni Battifta), wras born of a patri¬ cian family at Florence, in 1511. He wrote a Hiftory of his own Times in Italian ; which is a continuation of Guicciardini, beginning at the year 1536; to which" Thuanus acknowledges himfelf greatly indebted: be- fide which, he compofed fix funeral orations, on the em¬ peror Charles V. and other noble perfonages; and is thought to have been the author of a long letter on an¬ cient painters and fculptors, prefixed to the third vo¬ lume of Vafari. He died at Florence in 1579. ADRIANISTS, in ecclefiattical hiffory, a feft of heretics divided into two branches ; the firft were dif- ciples of Simon Magus, and flonriftied about the year 34. Theodoret is the only perfon who has preferved their name and memory; but he gives us no account of their origin. Probably this feft, and the fix others which fprung from the Simoniqns, took their name from the particular difciples of Simon. The fecond ■were the followers of Adrian Hamftead, the anabaptift; and held fome particular errors Concerning Chrift. ADRIANOPLE, a city of Turky in Europe, in the province of Romania, and the fee of an archbilhop under the patriarch of Conftantinople. It is about fe- ven or eight miles in circumference, including the old city and fome garden?. The houfes are low, moftly built of mud and clay, and feme of brick: and the 1 ftreets A D V [ 127 ] A D V Adrogation ftreets are exceeding dirty. The walls and towers are Advanced *n 3 £reat meafure fallen to decay. However, there is . V^’lC a beautiful bazar, or market, half a mile long, called Ali Baffa. It is a vaft arched building, with fix gates, and 365 well-furnifhed (hops, kept by Turks, Arme¬ nians, and Jews, wjio pay five crowns a-month for each (hop. The number of inhabitants of all nations and' religions may be about too,boo : but it i§ dear living here, becaufe the provifions are brought from diftant places. The air is wholefome, and the coun¬ try very pleafant in the fummer-time, on account of the river and ftreams that run near and about the city; the chief of which is the Mariza. Thefe promote and preferve the verdure of the gardens, meadows, and fields, for a confiderable part of the year. In the win¬ ter there is plenty of game. Near the principal ba¬ zar there is another, about a mile in length, covered with boards, with holes on each fide to let in the light. It is full of good Ihops, which contain all kinds of commodities. Sultan Selim’s mofque Hands on the. fide of a hill, in the midft of the city ; and hence this magnificent ftrufture may be feen on all fides. Every thing made of gold and filver, jewels, piftols, fcime- tars, &c. are fold in another part of the city, called by travellers the bizejlein, though it differs little from a bazar. This contains about 200 fhops, and is co¬ vered like the former: but the covering is fupported by two rows of large pillars. The grand vifier’s pa¬ lace is nothing more than a convenient houfe, after the Turkilh manner of building. The emperor’s feraglio is a regular ftructure, in a plain near the river Tungia. It is two miles in compafs, and has feven gates, be- fides thofe of the gardens, which are feveral miles in circumference. The city is governed by a mullah cadi, who has an abfolute authority both in-civil and crimi¬ nal matters. In the time of the plague, or war, the grand fignior fometimes refides here. The Turks took this city from the Greeks in 1362, and made it the capital of the empire,, till Mahomet II. took Conftan- tinople in 1453. E. Long. 26. 27. Lat. 41. 41.

ADVENT, in the calendar, properly fignifies the approach of the feaft of the nativity. It includes four fundays, which begin on St Andrew’s day, or on the funday before or after it. During advent, and to the end of the odlaves of epiphany, the folemnizing of marriage is forbid without a fpecial licence. It is ap¬ pointed to employ the thoughts of Chriftians on the firft advent or coming of Chrift in the flelh, and his fecond advent or coming to judge the world. The pri¬ mitive Chriftians practifed great aufterity during this feafon. ADventrem inspiciendum, inlaw, a.writ by which a woman is to be fearched whether {he be with child, by a former hulband, on her with-holding of lands1 from the next, failing iffue of her own body.

Ani'ENTURE-Bay, in Van Diemen’s land. There is a beautiful fandy beach, about two miles long, at, the bottom of Adventure Bay, formed to all. appearance, by the particles which the fea waffies from a fine white fand-ftone. This beach is very well, adapted for haul¬ ing a feine. Behind it is a plain, with a brackiih lake, out of which we caught, by angling, fome bream and trout. The parts adjoining the. bay are moftly hilly, and are an entire foreft of tall trees, rendered almoft impaffable by brakes of fern, Ihrubs, &c. The foil on the flat land, and on the lower part of the hills, is fandy, or confiits of a yellow!fh earth, and in fome parts of a reddiffi clay; but further up' the hills, it is of a grey tough call. This country, upon the whole,, bears.many.marks of being very dry, and the heat appears to be great. No mineral bodies, nor Hones of any other kind than the white fand-ftone, were obferved by us; nor could we find any vegetables that afforded fubfiftence for man. The foreft-trees are all of one kind, and generally quite ftraight: they bear clufters of fmall white flowers. The principal; plants obferved, are wood-forrel, milk-wort, cudweed, bell-flower, gladiolus, famphire, and feveral kinds of fern :. the only quadruped, a .fpecies of opoffum, about twice the fize of a large rat. The kangooroo, found further northward in New Holland, may alfo be fup- pofed to inhabit here, as fome of the inhabitants had pieces of the Ikin of that animal.

On the fhore were feveral gulls, black oylter- catchers, or fea-pies, and plovers of a {tone-colour. The inhabitants feemed mild and cheerful, with lit¬ tle of that wild appearance that favages in general have. They are almolt totally devoid of perfonal ac¬ tivity or genius, and are nearly upon a par wnth the wretched natives of Terra del Fuego. They difplay, however, fome contrivance in their method of cutting their arms and bodies in lines of different direftions, raifed above the furface of the {kin. Their indiffer¬ ence for prefents, their general inattention, and want of curiofity, were very remarkable, and teftified no acutenefs of underftanding. Their complexion is a dull black, which they fometimes heighten by fmut- iing their bodies, as was fuppofed, from their leaving a mark behind on any clean fubftance. Their hair is perfectly woolly, and is clotted with greafe and red Ochre, like that of the Hottentots. Their nofes are broad and full, and the lower part of the face projects confiderably. 'Their eyes are of a moderate lize, and though they are not very quick or piercing, they give the countenance a frank, cheerful, and pleafing caft. Their teeth are not. very white, nor well fet, and their mouths are too wide : they wear their beards long, and Clotted with paint. They are, upon the whole, well proportioned, though their belly is rather protuberant. Their favourite attitude is to {land with one fide for¬ ward, and one hand grafping, acrofs the back, the oppofite arm, which, on this occafion, hangs down by the fide that proje&s. ADVENTURER, in a general fenfe, denotes one who hazards fomething. Adventurers, is particularly ufed for an ancient company of merchants and traders, erected for the dif- covery of lands, territories, trades, &c. unknown. The fociety of adventurers had its rife in Burgundy, and its frit eftablifhment from John Duke of Brabant in I248, being known by the name of The brotherhood of St Thomas a Bechet. It was afterwards t ran dated into England, and fucceffively confirmed by Edward III. and IV. Richard III. Henry IV. V. VI. and VII. who gave it the appellation of Merchant Adven¬ turers. ADVERB, in grammar, a particle joined to a verb, adje£tive, or participle, to explain their manner of ac¬ ting or fullering; or to mark fome circumftance or quality fignified by them..

An adulterefs, by our law, undergoes no temporal pu- nifhment whatever, except the lofs of her dower ; and flie does not lofe even that, if her hufband is weak e- nough to be reconciled to her, and cohabit with her after the offence committed. 13 Ed. I. cap. 34. But it is to be obferved, that adultereffes are fuch either by the canon or civil law. According to the former, a woman is an adulterefs who, either being herfelf married, converfes Carnally with another man; or being fingle herfelf, converfrs with a man that is married. According to the latter, Hie is not an adul- tereis, if Hie be not herfelf in the married Hate, though Hie converfes with a man that is. The crime, in this cafe, was more properly calledJluprum than adulterium. Hence, among the Romans, the word adultera, “ a- dulterefs,” differed from pellex, which denoted a {in¬ gle woman who cohabited with a married man: and j| pellex differed from concubina, which fignified her who had only intercourfe with ah unmarried man. The former was reputed infamous, and the latter innocent. ADULTERATION, the aft of debafing, by an improper mixture, fomething that was pure and ge¬ nuine. The word is Latin, formed of the verb adulterare, “ to corrupt,” by mingling fomething foreign to any fubffance. We have laws againff the adulteration of coffee, tea, tobacco, fnuff, wine, beer, bread, wax, hair-powder, &c. Adulteration of Coin, properly imports the making, or caffing of a wrong metal, or with too bafe or too much alloy. Adulterations of coins are effected divers ways; as, by forging another ffamp or infeription; by mixing impure metals with the gold or filver: moff properly, by making ufe of a wrong metal, or an undue alloy, or too great an admixture of the bafer metals with gold or fdver. Counterfeiting the ftamp, or clipping and 3 A D U [ 129 ] AD U Adulfei ine, and leflening the weight, do not fo properly come under Adultery, denomination of adulterating.—Evelyn gives rules J"'v and methods, both of adulterating and dttefting a- dulterated metals, &c.—Adulterating is fomewhat lefs extenfive than debafwg, which includes diminilhing, clipping, &c. To adulterate or debafe the current coin, is a capi¬ tal crime in all nations.—The ancients punifhed it with great feverity : among the Egyptians both hands were cut off; and by the civil law, the offender was thrown to wild beafls. The emperor Tacitus enacted, that counterfeiting the coin fhould be capital; and under Conflantine it was made treafon, as it is alfo among us, The'adulterating of gems is a curious art, and the me¬ thods of detecting it no lefs ufeful. Nichols Lapid. p. 18. ADULTERINE, in the civil law, is particularly applied to a child iffued from an adulterous amour or commerce. Adulterine children are more odious than the illegitimate offspring of Angle perfons.—The Ro¬ man law' even refufes them the title of natural children; as if nature difowned them.—Adulterine children are not-eafily difpenfed with for admiffion to orders. Tliofe are not deemed adulterine, who are begotten of a wo¬ man 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 fubfequent marriage of the parties, even though a papal difpenfation be had for fuch marriage, wherein is a claufe of legitimation. Adulterine Marriages, in St Aliguftine’s fenfe, de¬ note fecond marriage's, contracted after a divorce. ADULTERY, jtn unlawful commerce between one married perfon and another, or between a married and unmarried perfon, Punifhments have been annexed to adultery in mod; ages and nations, though of different degrees of fCve- rity. In many it has been capital; in others venial, and attended only with flight pecuniary mul£ts. Some of the penalties are ferious, and even cruel; others of a jo- cofe and humorous kind. Even contrary things have ■been ena&ed as punifhments for adultery. By fome law's, the criminals are forbid marrying together, in cafe they became fingle; by others, they are forbid to marry any befides each other; by fome, they are inca¬ pacitated from ever committing the like crime again ; by others, they are glutted with it till it becomes downright naufeous. Among the rich Greeks, adulterers were allowed to redeem themfelves by a pecuniary fine; the woman’s father, in fuch cafes, returned the dower he had recei¬ ved from her hufband, which fome think was refunded by the adulterer. Another puniihment among thofe people was, putting out the eyes of adulterers. The Athenians had an extraordinary way of punifil¬ ing adulterers, called «?«?av5«SWif, practifed at leaf! on the poorer fort who were not able to pay the fines. This was an awkward fort of empalement, per¬ formed by thruffing one of the largeft radifhes up the anus of the adulterer, or, in defect thereof, a fifli with a large head, called mugil, “ mullet.” Alcseus is faid to have died this w ay, though it is doubted whether the punifhment was reputed mortal. Juvenal and Ca- * full us fpeak of this cuftom, as received alfo among the Romans, though not authorifed by an exprefs law, as it was among the Greeks. Vol. I. Part I. There are various conje&ures concerning the anci- Adultery, ent punifhment of Adultery among the Romans. Some will have it to have been made capital by a law of Ro¬ mulus, and again by the twelve tables. Others, that it was firfl made capital by Auguftus; and others, not befoi-e the emperor Conftantine. The truth is, the pu¬ nifhment in the early days was very various, much be¬ ing left to the diferetion of the hufband and parents of the adulterous wife, who exercifed it differently, rather with the filence and countenance of the magiftrate than any formal authority from him. Thus we are told, the wife’s father was allowed to kill both parties, when caught in the fa6t, provided he did it immediately, kill¬ ed both together, and as it w-ere with one blow'. The fame power ordinarily was not indulged the hufband, except the crime were committed wfith fome mean or infamous perfon ; tho% in other cafes, if his rage car¬ ried him to put them to death, he was not punifhed as a murderer. On many occafions, however, revenge was not carried fo far; but mutilating, caflrating, cutting -off the ears, nofes, See. ferved the turn. The punifh¬ ment allotted by the lex Julia, w'as not, as many have imagined, death; but rather banifhment, or deporta¬ tion, being interdi&ed fire and water: though Oftavius appears, in fev“ral inflances, to have gone beyond his own law, and to have put adulterers to death. Un ¬ der Macrinus, many were burnt at a flake. Conilantine firll by law made the crime capital. Under Conftan- tius and Conflans, adulterers were burnt, or fewed in lacks and thrown into the fea. Under Leo and Maf- cian, the penalty was abated to perpetual banifhment, or cutting off the nofe. Under Juftinian, a further mi¬ tigation w'as granted, at leafl in favour of the wife, who was only to be fcourged, lofe her dower, and be fhut up in a monaflery: after two years, the hufband was at li¬ berty to take her back again; if he reftlfed, fhe was fha- ven, and made a nun for lifeBut it ftill remained death in the hufband. The reafon alleged for this difference is, that the woman is the weaker veffel. Matthaeus de¬ claims againfl the emprefs Theodora, who is fuppofed to have been the caufe of this law, as Well as of otherg procured in favour of that fex from the emperor. Under Theodoffus, women convicted of this crime were punifhed after a very Angular manner, viz. by a public conflupration ; being locked up in a narrow' cell, and forced to admit to their embraces all the men that Would offer themfelves. To this end, the gallants were to drefs themfelves on purpofe, having feveral little bells faftened to their clothes, the tinkling of which gave notice to thofe without of every-motion. This cuflont' was again aboliflied by the fame prince. By the Jewifh law', adultery was punifhed by death in both parties, where they were both married, or on¬ ly the w'pman. The Jew's- had a particular method of trying, or rather purging, an adulterefs, or a woman fufpedled of the crime, by making her drink the bit¬ ter waters of jealoufy ; w'hich, if fhe were guilty, made her fwell. Among the Mingrelians, according to^Chardin, a» dultery is punifiled with the forfeiture of a hog, which is ufually eaten in good friendfhip between the gallant; the adulterefs, and the cuckold. In fome parts of the Indies, it is faid any man’s wife is permitted to pro- flitute herfelf to him who will give an elephant for the ufe of her; and it is reputed no fmall glory to her to R have A D U [ 130 ] A D U Adultery, have been rated fo high. Adultery is faid to be fe> ' v ’ frequent at Geylon, that not a woman but praftifes it, notwithftanding its being punifhable with death. A- naong the Japanefe, and divers other nations, adultery is only penal in the woman. Among the Abyffinians, the crime of the hufband is faid to be only p uni died on the innocent wife. In the Marian illands, on the con- trary, the woman is not punilhable for adultery ; but if the man go aftray he pays feverely: the wife and her relations wafte his lands, turn him out of his houfe, &c. Among the Chinefe, there is reafon to conclude that adultery is not capital; for it is faid that fond pa¬ rents will make a contract for their daughters future hufbands to allow them the indulgence of a gallant. In Spain, they punifhed adultery in men by cutting off that part which had been the inftrument of the crime. In Poland, before Chriftianity was eftablifhed, they punifhed adultery and fornication in a very parti¬ cular manner: the criminal they carried to the mar¬ ket-place, and there fattened him by the tefticles with a nail; laying a razor within his reach, and leaving him'under a necefiity, either of doing juftiee upon himfelf Or of perifhing in that condition. The Saxons formerly burnt the adulterefs, and over her afhes erected a gibbet, whereon the adulterer was hanged. In this kingdom, likewife, adultery, by the ancient laws, was feverely punifhed. King Edmund the Saxon ordered adultery to be punifhed in the fame manner as homicide ; and Canute the Dane ordered that a man who committed adultery fhould be banifh- ed, and that the woman fhould have her nofe and ears cut off. In the time of Henry I. it was punifhed with : the lofs'of eyes and genitals. In Britain, adultery is reckoned a fpiritual offence, that is, cognizable by the fpiritual courts, where it is punifhed by fine and penance. Tire common law takes no farther notice of it, than to allow the party grie¬ ved an action and damages. This practice is often cen- fured by foreigners, as making too light of a crime, the bad conlequences of which, public as well as pri¬ vate, are fo great. It has been anfwered, that per¬ haps this penalty, by civil a6tion, is more wifely cal¬ culated to prevent the frequency of the offence, which ought to be the end of all laws, than a feverer punifh- ment. He that by a judgment of law is, according to circamitances, ftripped of great part of his fortune, thrown into prifon till he can pay it, or forced to fly his country, will, no doubt, in molt cafes, own that he pays dearly for his amufement. As to the moral turpitude of this offence, fome have vainly endeavoured to deny or explain it away by va¬ rious arguments, and even by an appeal to feripture. On the part of the man who folicits the chaitity of a married woman, it certainly includes the crime of se¬ duction, and is attended with mifehief ftill more complicated and extenlive : It creates a new fufferer, the injured hufband, upon whofe fimplicity and affec¬ tion is inflicted a wound the mofl; painful and incu- frable that human nature knows. The infidelity of the •woman is aggravated by cruelty to her children, who -kre generally involved in their parents fhame, and al¬ ways made unhappy by their quarrel. It has been argued, that thefe confequences ought lefs'to be attributed to the crime than to the difeovery. But, in the firft place, the crime could not be difeo- vered unlefs it were committed, and the commiflion is Adultery, never fecure from difeovery. 2-dly, If adulterous con- v""~ neftior.s were allowable whenever the parties could hope to efcape detection, which is the conclufion to which this argument leads, the hufband would be left no other fecurity for his wife’s chaflity, than in her want of op¬ portunity or temptation : which would probably deter moft men from marrying; or render marriage a ftate of continual jealoufy and alarm to the hufband, which would end in the flavery and confinement of the wife. The marriage-vow is “ witneffed before God,” and accompanied with circumflances of folemnity and re-* ligiomwhich Approach to the nature of an oath. The married offender, therefore, incurs a crime little fhort of perjury, and the fedu&ion of a married woman is little lefs than fiibornation of perjury :—and this guilt is independent of the difeovery. But the ufual apology for adultery is the prior tranf- greflion of the other party ; and fo far, indeed, as the bad effeils of adultery are anticipated by the conduct of the hufband or wife- who offends firff, the guilt of the fecond offender is extenuated. But this can never amount to a juftification ; unlefs it could be fhown that the obligation of the marriage-vow depends upon the condition of reciprocal fidelity ; a conftruTion which appears founded neither in expediency, nor in the tei/ns of the vow, nor in the defign of the legiflature which preferibed the marriage-rite. The way of confidering the offence upon the footing of provocation and retali* ation, is a childifh trifling with words.. “ Thou fhalt not commit adultery,” was an inter* diet delivered by God himfelf; yet feriptuve has been adduced as giving countenance to the Crime. As Chrift told the woman taken in adultery, “ Neither do 1 con*, demn thee,” we muff believe, it is faid, that he deemed her condutd either not criminal, or at leaft not a crime of the heinous nature we reprefent it to be.. But from a more attentive examination of the cafe, it will be evident that nothing can be concluded from it favour¬ able to fuch an opinion. The tranfaction is thus re¬ lated * :. ‘ Early in the morning Jefus came again in- * gt John'* ‘ to the temple, and all the people came unto him ; Gofyel, ‘ and he fat down and taught them ; and the Scribes ck ' ‘ and Pharifees brought unto him a woman taken in ‘ adultery; and when they had fet her in the midft, ‘ they fay unto him, Mailer, this woman was taken ‘ in adultery, in the very aft ; now Mofes in the law ‘ commanded that fuch fhould be Honed, but what ‘ fayefl thou ? This they faid tempting him, that they ‘ might have to aceufe him : but Jefus Hooped down, ‘ and with his finger wrote on the ground, as though ‘ he heard them not. So when they continued a living ‘ him, he lift up himfelf, and faid unto them, He that ‘ is without fin amongfi you, let him firfi cafi a ‘ Hone at her; and again, he Hooped down and wrote • on the ground : and they which heard it, being con- ‘ vifted by their own confcience, went out one by one, ‘ beginning at the eldell, even unto the lall; and J-r- ‘ fus was left alone, and the woman Handing in the ‘ midH. - When Jefus hud lift up himfelf, and faw none ‘ but the woman, he faid unto her. Woman, where ‘ are thofe thine aceufers ? .Hath no man condemned ‘ thee ? She faid uiito him. No man. Lord : and he ‘ faid unto her, Neither do I condemn thee; go and fin 1 no more. ‘ This Paley’s Moral and Politic, il Pbilofophy, p. 258. 3d edit. 4tO. * De Serm Dom. in Mont. lib. i tap. r6. § 49. ct Dt Civ. Dei, lib. xvi. cap. aj. A D U [ 1 ‘ This they faid tempting him, that they might ‘ have to accufe him that is, to draw him into an exercife of judicial authority, that they might have to accufe him before the Roman governor of ufurping or intermeddling with the civil government. “ This was their defign ; and Chrift’s behaviour throughout the whole affair proceeded from a know¬ ledge of this defign, and a determination to defeat it. He gives them at firfi: a cold and fullen reception, well fuited to the infidious intention with which they came : * he flooped down, and with his finger wrote on ‘ the ground as though he heard them not.’ * When * they continued afking him,’ when they teazed him to fpeak, he difmiffed them with a rebuke, which the impertinent malice of their errand, as well as the fe- cret charafter of many of them, deferred : ‘ he that is ‘ without fin (that is, this fin) among you, let him ‘ firft call a ftone at her.’ This had its effect. Stung with the reproof, and difappbinted of their aim, they ftole away one by one, and left Jefus and the woman alone. And then follows the converfation, which is the part of the narrative moil material to our prefent fubject. ‘ Jefus faith unto her, Woman, where are ‘ thofe thine accufers ? Hath no man condemned thee ? 4 She faid, No man, Lord. And Jefus faid unto her, 1 Neither do I condemn thee; go and fin no more.’ Now, when Chrifl afked the woman, ‘ Hath no man ‘ condemned thee ?’ he certainly fpoke, and was under- flood by the woman to fpeak, of a legal and judicial condemnation ; otherwife her anfwer, ‘ No man, Lord,’ was not true. In every other fenfe of condemnation, as blame, cenfure, reproof, private judgment, and the like, many had condemned her; all thofe, indeed,who. •brought her to Jefiis. If then a judicial fentence was what Chrift meant by condemning in the queflion, the common ufe of language requires us to fuppofe that lie meant the fame in his reply, ‘ Neither do I con- ‘ demn thee i. e. I pretend to no judicial character or authority over thee; it is no office or bufinefs of mine to pronounce or execute the fentence of the law. When- Chrifl adds, ‘ Go and fin no more,’ he in effedl tells her that fhe had finned already ; but as to the degree or quality of the fin, or Chrifl’s opinion con¬ cerning it, nothing is declared, or can be inferred, ei¬ ther way.” It has been controverted, whether adultery may be lawfully committed in war, with the enemies wives ? The anfwer is in the negative, and the authorifed prac¬ tice of civilized nations is agreeable to this. It has alfo been a famous queflion, whether it be lawful for a woman to commit adultery with the confent of her hufband, and for the procuring fome great good to him ? St Auilin apparently allows of it; at leafl, does not condemn it *. It has likewife been a difpute, whether it be lawful for one of the parties married to commit adultery, with the confent of the other, for the fake of having chil¬ dren ? Of which we have in fiances in Abraham, who, on this account, converfed with Hagar; and likewife among the Greeks and Romans. Pollman, a German profeffor, has a difiertation on the hufband’s right to alienate his wife’s body to another’s ufe. It is much difputed, whether adultery diffolves the bond of matrimony, and be a fufficient caufe 0/ di¬ vorce:., fo that the parties may marry again.

When the ille of zEgina wanriepopulated by a plague, his fa¬ ther, in compaffion to his grief, changed all the ants upon it into men and women, who wpre called Myrmi¬ dons, from an ant. The foundation of the fa¬ ble is faid to be, that when the country had been de¬ populated by pirates, who forced the few that remain¬ ed to take Ihelter in caves, YEacus encouraged them to come out, and by commerce and induftry recover what they had loft. His character for juftice was fuch, that, in a time of univerfal drought, he was nominated by the Delphic oracle to intercede for Greece, and his prayer was anfwered. See the article YEgina. The Pagans alfo imagined that YEacus, on account of his impartial juftice, was chofen by Pluto one of the three judges of the dead : and that it was his province to judge the Europeans.

See the next article. iEDILE (tedilis), in Roman antiquity, a magillrate whofe chief .bufinefs was. to fuperintend buildings of all kinds, but more efpecially public ones, as temples, aquaedufts, bridges, &c; To the ,aediles likewife be¬ longed the care of the highways, public places, weights and meafures, &c. They alfo fixed the prices of pro- vifions, took cognizance of debauches, punifhed lewd women, and fuch perfons as frequented gaming houfes. The cuftody of the plebifcita, or orders of the people, was likewife committed to them. They had the infpec- tion of comedies and other pieces of wit; and were ob¬ liged to exhibit magnificent games to the people, at their own expence, whereby many of them were ruin¬ ed. To them alfo belonged the cuftody of the ple¬ bifcita, and the cenfure and examination of books. They had the power, on certain occafions, of iffuing edifts; and, by degrees, they procured to themfelves a confiderable junTdidtion, the 'cognizance of various caufes, &c. This office ruined numbers by its expen- fivenefs ; fo that, in Auguftus’s time,, even many fe- nators declined it on that account. All thefe funftions which rendered the aediles fo con¬ fiderable belonged at firft to the aediles of the people, adiles plebeii, of minores : thefe'were only two in num¬ ber, . and were firft created in the fame year as the tri¬ bunes : for the tribunes, finding themfelves oppreffed with the multiplicity of affairs, demanded of the fe- nate to have officers, with whom they might intruft matters of lefs importance ; and accordingly two aediles were created; and hence, it was that the aediles were elected every year at the fame affembly as the tribunes. But -thefe plebeian aediles having refufed, on a fignah pccafion,' to treat the people with- fhows, as pleading themfelves. unabl'e to fupprirt the expence thereof, the patricians made an offer to do it, provided they would admit them to the honours of the cedildte. On this oecafion there were two new sediles 'created, of the number of the patricians, in the year of Rome 388 ; they were called tediles curules, or major es ; as having a right to fit on a curule chair, enriched with .ivory, when they gave audience ; whereas the plebeian aediles only fat on benches.—Befides that the curule aediles fhared all the ordinary functions with the plebeian, their chief employ was, to procure the. celebration of the grand Roman games, and. to exhibit comedies, 'ftiews of gladiators, &c. to the people; aiid they were alfo appointed judges in all cafes relating to the felling or exchanging eftates.- To eafe thefe four firft aediles, Caefar created a new kind, called idiles cere ales, as being deputed chiefly to take care of. the corn, which was called donum cereris; for the Heathens honoured Ceres as, the goddefs who prefided over corn, and attributed to her the, invention of agriculture. Thefe aediles cereales were alfo taken out of the order of patricians, in tire municipal ci¬ ties there were aediles, and with the fame authority as at Rome.

AEGEAN sea (anc. geog.),' now the Archipelago, a part of the Mediterranean, feparating Europe from Afia and Africawalking, on the one hand, Greece and Macedonia ; on the other, Caria and Ionia.

Feftus advan¬ ces three opinions : one, that it is fo called from the many iflands-therein, at a diftanee appearing like fo many goats : ■ another, .becaufe iEgea queen of the Amazons perilhed in it: a third opinion is, becaufe iEgeus, the father of Thefeus, threw himfelf headlong into it. iEGEUS, in fabulous hiftory, was king of Athens, and the father of Thefeus. The Athenians having bafcly killed the fon of Minos king of Crete, for carry¬ ing away the prize from them, Minos made war upon the'Athenians; and being victorious, impofed this fevere condition.on zEgeus, that he ihould annually fend into Crete feven of. the nobleft of the Athenian youths, . chofen by lot, to be devoured by the Minotaur. On the fourth year of this tribute, the choice fell on The¬ feus ; or, as others fay, he himfelf intreated to be fent. The king, at his fon’s departure, gave orders, that as the Ihip failed with black fails, it Ihould return with the fame in cafe he perilhed ; but, if he became victorious, he Ihould change them into white. When Thefeus re¬ turned to Crete, after killing the Minotaur, and for¬ got to change. the fails in token of his victory, ac¬ cording to the agreement v/ith his father; the latter; who watched the return of the veffel, fuppofing by the black fails that his fon was dead, call hiinfelf head¬ long into the fea, which afterwards obtained the name of the Mgean Sea.

Authors frequently ufe the words agilops, anchilops, and fijhda lachrymalis, promifcuoufly ; but the more accurate, after jEgineta, make a difference.—The tu¬ mor, before it becomes ulcerous, is properly called an¬ chilops; and, after it is got into the lachrymal paffages, and has rendered the os lachrymale carious, fiftula la¬ chrymals s. If the asgilops be accompanied with an inflamma¬ tion, it is fuppofed to take its rife from the abundance of blood which a plethoric habit difcharges on the cor¬ ner of the eye. If it be without an inflammation, it is fuppofed to proceed from a vifcous pituitous humour, thrown upon this part. The method of cure is the fame as that of the oph¬ thalmia. But before it has reached the lachrymal paf¬ fages, it is managed like other ulcers. If the aegilops be neglected, it burlts, and degenerates into a fiftula, which eats into the bone. M.GW.otWildFejluc; a genusofthemonoeciaorder, belonging to the polygamia clafs of plants, and ranking under the 4th natural order, Gramina.—The charadlers are : The hermaphrodite calyx is a two-valved glume, tri- florous; the corolla a two-valved glume, the exterior valvalet terminated by three r,rift32 or awns, the interior awnlefs : Stamina, three capillary filaments ; ftyle, two'. Seed, one, oblong. Male calyx and corolla, each a glume ais in the former ; and Jiamina, the fame number.— There are feven fpecies, natives of Italy and fome other parts of Europe ; one of them, the incurvata, a native of Britain, grows by the fea-fhore, and is vulgarly call¬ ed fea-hard-grafs. yEcmoPS is alfo the trivial name of a fpecies of QmER.cus. .EGIMURUS (anc. geog.), an ifland.on the bay of Carthage, about 30 miles diftant from that city, .{Livy) ; now the Galetta: This illand being after¬ wards funk in the fea, two of its rocks remained above water, which were called slrai, and mentioned by Vir¬ gil, becaufe the Romans and Carthaginians entered in¬ to an agreement or league to fettle their mutual boun¬ daries at tliefe rocks. jEGJNA, in fabulous hiftory, the daughter of iE- •fopus, king of Beotia, was beloved by Jupiter, who debauched her in the fimilitude of a lambent flame, arid then carried her from Epidaurus to a defart ifland called Oenope, which afterwards obtained her own name. xEgina (anc. geog.), an ifland on the Saronic Bay, or Bay of Engia, 20 miles diftant from the Piraeus, formerly vying with .Athens for naval power, and at the fea-fight of Salamin difputing the palm of viftory with the Athenians. It was the country and kingdom, of JEacus, who called it JEgina from his mother’s name, it being before called Oenopia, (Ovid). The inhabi¬ tants were called JEginetec, and JF.ginenfes. The Greeks ■ -N° 4. had a common temple dedicated to Jupiter in iEgina. The vEginetas applied to commerce ; and were the firft who coined money, called 'Ayivaio': hence JE- gineticum res, formerly in great repute. The inhabi¬ tants were called Myrmydones, or a nation of ants, from their great application to agriculture. See JHa- cvs. This ifland was furrounded by Attica, the territory of Megara, and the Peloponnefus, each diftant about 100 ftadia, or 12 miles and a half. In circumference it was reckoned 180 ftadia, or 22 miles and a half. It was wafhed on the eaft and fouth by the Myrtoan aad Cre¬ tan feas. It is now called Eyina, or Egina, the g foft and the i Ihort. The temple above-mentioned is fituated upon the fummit of a mountain called Panhellenius, about an hour diftant from the Ihore. The-fEginetans affirm* ed it was eredled by ALacus ; in whofe time Hellas being terribly oppreffed by drought, the Delphic oracle was confulted ; and the refporife was, That Jupiter muft be rendered propitious by fEacus. The cities intreat- ed him to be their mediator: He facrificed and prayed to Jupiter Panhellenius, and procured rain. The temple was of the Doric order, and had fix co¬ lumns in front. Twenty-one of the exterior columns are yet Handing, with two in the front of the pronaos and of the potticum, and five of the number which formed the ranges of the cell. The entablature, except the architrave, is fallen. The ftone is of a light brown- ifh colour, much eaten in many places, and indicating a very great age. Some of the columns have been in¬ jured by boring to their centres for the metal. In fe- veral, the junction of the parts is fo exaft, that each feems to confift of one piece. This ruin Mr Chandler confiders as fcarcely to be paralleled in its claim to a remote antiquity. The fituation on a lonely mountain, at a diftance from the fea, has preferred it from total demolition, amid all the changes and accidents of nu¬ merous centuries. Near the fliore is a burrow, raifed, it is related, for Phocus, upon the following occafion. Telamon and Peleus, fons of JEacus, challenged their half-brother Phocus to contend in the Pentathlum. In throwing the ft/>ne, which ferved as a quoit, Peleus hit Phocus, who was killed; when both of them fled. Afterwards, Telamon fent a herald to aflert his innocence. iEacus would not fuffer him to land, or to apologize, except from the veffel; or, if he chofe rather, from a heap call up in the water. Telamon, entering the private port by night, raifed a barrow, as a token, it is likely, of a pious regard for the deceafed. He was afterwards condemned, as not free from guilt; and failed away a- gain to Salami’s. The barrow in the fecond century, when feen by Paufanias, was furrounded with a fence, and had on it a rough ftone. The terror of fome dreadful judgment to be inflicted from heaven had pre- ferved it entire and unaltered to his time ; and in a country depopulated and neglecfted, it may ftill endure for many ages. The foil of this ifland is, as deferibed by Strabo, very ftony, efpecially the bottoms, but in fome places not unfertile in grain. Befides corn, it produces olives, grapes, and almonds ; and abounds in pigeons and partridges.

JEGIUM, (anc. geog.) a town of Achaia Propria, five miles from the place where Helice flood, and fa¬ mous for the council of the Acheans, which ufually met there on account either of the dignity or commodious Situation of the place. It was alfo famous for the wor- ftiip of Oftxyvgtos Ttv(, Conventional Jupiter, and of Pa- nackaan Ceres. The territory of Aigium was watered by two rivers, viz. the Phoenix and Meganitas. The epithet is JEgienfts.

There is but one fpecies, a native of Britain and other parts of' Europe. It is very common under hedges and about gardens; the leaves refemble thofe of Angelica, and it carries fmall white flowers. Its roots run fo fall, as to- render it a very troublefome weed. .lEGOPRICON, a genus of the monoecia order, be¬ longing to the diandria clafs of plants ; the charafters of which are : The calyx both of the male and female is a tubular perianthium of one leaf divided into three fegments : Corolla wanting in both : Theflamina con- fifl of a Angle ereft filament longer than the calyx, with an ovate anthera: The pijlillum has an ovate germen, three divaricated ftyli, and fimple perfiftent ftigmata : The pericarpium is a globular berry, three-grained with¬ in, and three-cell’d : The feeds are folitary, and angu¬ lar on one fide.—There is but one fpecies, a native of Surinam. .dEGOSPOTAMOS, (anc. geog.), a river in the Thracian Cherfonefys, falling with a fouth-eaft courfe into the Hellefpont, to the north of Sefios ; alfo a -®gofpo( town, ftation, or road for fnips, at its mouth. Here ™os‘ the Athenians, under Conon, through the fault of his 'r“ colleague Ifocrates, received a iignal overthrow from the Lacedemonians under Lyfander, which was follow¬ ed by the taking of Athens, and put an end to the Peloponnefian war. The Athenian fleet having fol¬ lowed the Lacedemonians, anchored in the road, over againft the enemy, who lay before Lampfacus. Tbe Hellefpont is not above two thoufand paces broad in that place. The two armies feeing themfelves fo near each other, expefted only to reft that day, and were in hopes of coming to a battle on the next. But Lyfander had another defign in his view. He commanded tbe feamen and pilots to go on board their galleys, as if they were in reality to fight the next morning at break of day, to hold themfelves in readi- nefs, and to wait his orders with profound filence. He commanded the land-army in like manner to draw up in battle upon the coaft, and to wait the day with¬ out noife. On the morrow, as foon as the fun was ri- fen, the Athenians began to row towards them with their whole fleet in one line, and to bid them defiance. Lyfander, though his ftiips were ranged in order of battle, with their heads towards the enemy, lay ftill without making any movement. In the evening, when the Athenians withdrew, he did not fuffer his foldiers to go alhore, till two or three galleys, which he had fent out to obferve them, were returned with advice that they had feen the enemy land. The next day paffed in the fame manner, as did the third and fourth. Such a conduft, which argued referve and apprehen- fion, extremely augmented the fecurity and boldnefs of the Athenians, and infpired them with an extreme contempt for an army, which fear, in their fenfe, pre¬ vented from ftiowing themfelves, and' attempting any thing. WhHft this paffed, Alcibiades, who was near the fleet, took horfe, and came to the Athenian generals u to whom he reprefented, that they kept upon a very difadvantageous coaft, where there were neither ports nor cities in the neighbourhood ; that they were ob¬ liged to bring their provifions from Ceftos. with great danger and difficulty ; and that they were very much in the wrong to fuller the foldiers and mariners of the fleet, as foon as they were aftiore, to ftraggle and difperfe themfelves at their own pleafure, whilft they were faced in view by the enemy’s fleet, ac- cuftomed to execute the orders of their general with the readieft obedience, and upon the flighteft fignal. He offered alfo to attack the enemy by land with a ftrong body of Thracian troops, and to force them to- a battle. The generals, efpecially Tydeus and Me¬ nander, jealous of their command, did not content themfelves with refufing his offers,, from the opinion, that if the event proved unfortunate, the whole blame would fall on them, and if favourable, that Alcibiades alone would have the honour of it; but rejefted alfo. with infult his wife and falutary counfeLas if a man in difgrace loft his fenfe and abilities with the favour of the common-wealth. Alcibiades withdrew. The fifth day the Athenians prefented themfelves again, and offered battle; retiring in the evening ac¬ cording to cuftom with more infulting airs than the days before. Lyfander, as ufual, detached fome gal¬ leys to obferve them, with orders, to, return with the utmoft: JE G r [ 139 ] iE M 1 ^gnfpoti- utmoft diligence when they faw the Athenians land- "J.09 ed, and to put up a brazen buckler at each (hip’s head ^ggypt'lla. a? foon as they reached the middle of the channel. c_—v Himfelf in the mean time ran through the whole line in his galley, exhorting the pilots and officers to hold the feamen and foldiers in readinefs to row and fight on the firft fignal. As foon as the bucklers were put up in the (hips heads, and the admiral galley had given the fignal by the found of trumpet, the whole fleet fet forward in good order. The land-army at the fame time made all poffible.halle to the top of the promontary to fee the battle. The ftrait that feparates the two continents in this place is about fifteen lladia, or three quarters of a league in breadth ; which fpace was prefently clear¬ ed through the activity and diligence of the rowers. Conon the Athenian general was the firft who percei¬ ved from (hore, that fleet advance in good order to at¬ tack him ; upon which he immediately cried out for the troops to embark. In the height of forrow and trouble, fome he called to by their names, fome he conjured, and others he forced to go on board their galleys; 'but all his endeavours and emotion were inef- feftual, the foldiers being difperfed on all fides. For they were no fooner come on (hore, than fome run to the futlers, fome to walk in the country, fome to deep in their tents, and others had begun to drefs their fuppers. This proceeded from the want of vigi¬ lance and experience in their generals, who, not fuf- pefting the lead danger, indulged themfelves in their taking repofe, and gave their foldiers the fame li¬ berty. The enemy had already fallen on with loud cries and a great noife of their oars, when Conon, difengaging himfelf with nine galleys, of which number was the fa- cred (hip called the Paralian, flood away for Cyprus, where he took refuge with Evagoras. The Pelopon- nefians, falling upon the reft of the fleet, took imme¬ diately the galleys which were empty, and difabled and deftroyed fuch as began to fill with men. The foldiers, who ran without order or arms ,to their relief, were ei¬ ther killed in the endeavour to get on board, or flying on fhore were cut to pieces by the enemy, who landed in purfuit of them. Lyfander took 3000 prifoners, with all the generals, and the whole fleet. After ha¬ ving plundered the camp, and faftened the enemy’s galleys to the fterns of his own, he returned to Lamp- - facus amidft the found of flutes and fongs of triumph. It was his glory to have atchieved one of the greateft military exploits recorded in hiftory with little or no lofs, and to have terminated a war in the fmall fpace of an hour, which had already lafted 27 years, and which, perhaps, without him, had been of much longer continuance. jEGYPT.

He was likewife honoured with the title of Sophift, an appellation in his days given only to men of learning and wifdom. He loved retirement, and devoted himfelf to ftudy. He greatly admired and ftudied Plato, Ariftotle, Ifocrates, Plutarch, Homer, Anacreon, Archilochus, &c. and, though a Roman, gives the preference to the writers of the Greek nation. His two moft celebrated works are, his Various Hi¬ ftory, and Hiftory of Animals.

The Form of /Enigmas confifts in the words, which, whether they be in profe or verfe, contain eitherLome defeription, a queftion, or a profopopaeia. The laft kind are the moft pleafing, inafmuch as they give life and aftion to things which other wife have them not. To make an aenigma, therefore, two things are to be pitched on, which bear fome refemblance to each other; as the fun and a monarch; or a ft) ip and a houfe: and on this refemblance is to be raifed a fuperttrufture of contrarieties to amufe and perplex. It is eafier to find great fubjefts for aenigmas in figures than in words, inafmuch as painting attrafts the eyes and ex¬ cites the attention to difeover the fenfe. The fubjefts of enigmas in painting, are to be taken either from hiftory or fable : the compofition here is a kind of me- tamorphofis. JE N I [ 141 ] iE N I Enigma, tamorphofis, wherein, e. g. human figures are chan- u“—''v'™' 1 ged into trees, and rivers into metals. It is effential to asnfgmas, that the hiftory or fable, under which they are prefented, be known to every body j other- wife it will be two cenigmas in (lead of one; the firft of the hiftory or fable, the fecond of the fenfe in which it is to be taken. Another effential role of the aenigma is, that it only admit of one fenfe. Every senigma which is fufceptive of different interpretations, all equally na¬ tural, is fo far imperfeft. What gives a kind of erudi¬ tion to an asnigma, is the invention of figures in fitua- tions, geftures, colours, &c. authorifed by paffages of the poets, the cuftoms of artifts in ftatues, baffo relievos, infcriptions, and medals.—In foreign colleges, The Explication of Enigmas makes a confiderable exercife; and that one of the moft difficult and amu- fing, where wit and penetration have the largeft field. —By explaining an aenigma, is meant the finding a motto correfponding to the attion and perfons repre- fented in a pifture, taken either from hiftory or my¬ thology. The great art of this exercife confifts in-the choice of a motto, which either by itfelf, or the cir- cumftances of time, place, perfon who fpeaks, or thofe before whom he is fpeaking, may divert the fpeftators, and furnifti occafion for ftrokes of wit; alfo in ftiowing to advantage the conformities between the figure and thing figured, giving ingenious turns to the reafons employed to fupport what is advanced, and in artfully- introducing pieces of poetry to illuftrate the fubjedf and. awaken the attention of the audience. As to the folution of senigmas, it may be obfer- ved, that thofe expreffed by figures are more difficult to explain than thofe confifting of words, by reafon images may fignify more things than words can ; ,fo that to fix them to a particular fenfe,. we muft apply every fituation, fymbol, &c. and without omitting a circumftance. — As there are few perfons in hiftory, or mythology, but have fome particular character of vice or virtue, we are, before all things, to attend to this cbaratt^r, in order to divine what the figure of a per¬ fon reprefented in a painting fignifies, and to .find what, agreement this may have with the fubjedf whereof we would explain ita Thus, if Proteus be reprefented in a picture, it maybe taken to denote inconftancy, and applied either to a phyfical. or moral fubjtcft, whofe charafter is to be changeable; e. g. an almanack, which' expreffes the weather, the feafons, heat, cold, ftorms, and the like. The colours of figures may alfo help to unriddle what they mean : •white, for inftance, is a mark of innocence, red of modefty, green of hope. Hack of forrow, &c. When figures are accompani¬ ed with fymbols, they are lefs precarious ; thefe being, as it were, the foul of. enigmas, and the key that opens the myftery of them. Of all the kinds of fym¬ bols which may be met with in thofe wdio have treated profeffedly on the fubjecf, the only truly senigmatical are thofe of Pythagoras, which, under dark proverbs, hold forth leffons of morality ; as when he fays, State- ram ne tranflias, to fignify, Do no injuftice. But it muft be added, that, we meet with fome senig- mas in hiftory, complicated to a degree, which much tranfcends all rules, and has given great perplexity to the interpreters of them. Such is that celebrated > ancient one, JEha La-lia Crifpis, about which many of the learned have puzzled their heads. There are two exemplars of it: one found 140 years ago, on a mar> iEniguia. ble near Bolognia : the other in an ancient MS. writ- ' ten in Gothic letters, at Milan. It is controverted be¬ tween the two cities, which is to be reputed the more authentic. The Bononian JEnigma. D. M.

EOLIPILE, in hydraulics, is a hollow ball of me¬ tal, generally ufed in courfes of experimental philofo- phy, ih order to demonftrate the poffibility of convert¬ ing water into an elaftic fteam or vapour by heat. The inftrument, therefore, confifts of a flender neck, or pipe, having a narrow orifice inferted into the ball by means of a Ihouldered fcrew. This pipe being taken out, the ball is filled almoft full of water, and the pipe 2 being again fcrewed in, the ball is placed on a pan or kindled charcoal, where it is well heated, and there iffues from the orifice a vapour, with prodigious vio¬ lence and great noife, which continues till all the in¬ cluded water is difcharged. The ftronger the fire is, the more elaftic and violent will be the fteam ; but care muft be taken that the fmall orifice of the pipe be not, by any accident, flopped up; becaufe the inftrument would in that cafe infallibly burft in pieces, with fuch violence as may greatly endanger the lives of the per- fons near it. Another way of introducing the water is to heat the ball red-hot when empty, which will drive out almoft all the air; and then by fuddenly immerg- ing it in water, the preflure of the atmofphere will force in the fluid, till it is nearly full. Des Cartes and o- thers have ufed this inftrument to account for the na¬ tural caufe and generation of the wind : arid hence it was called JEolopila: q. d. pila JEoli, the ball of Eolus or of the god of the winds. EOLIS, or Eolia (anc. geog.), a country of the Hither Afia, fettled by colonies of Eolian Greeks. Taken at large, it comprehends all Troas, and the coaft. of the Hellefpont to the Propontis, becaufe in thofe parts there were feveral Eoliaa colonies: more ftrictly, it is fituated between Troas to the north, and Ionia to the fouth. The people are called Mclss, or JEolii. EOLIUM -MARE (anc. geog.), a part of the Egean fea, waflring Eolis; called alfo Myftum, from Myfia. Now called, Golfo di Smyrna. EOLUS, in heathen mythology, the god of the winds, was faid to be the fon of Jupiter by Acafta, or Sigefia, the daughter of Hippotus; or, according to others, the fon of Hippotus by Meneclea, daughter of Hyllus king of Lipara. He dwelt in the ifland Strongyle, now called Strombolo, one of the feven iflands called JEolian from their being under the do¬ minion of Eolus. Others fay, that his refidence was at Regium, in Italy; and others again place him in the ifland Lipara. He is reprefented as having autho¬ rity over the winds, which he held enchained in a vaft cavern, to prevent their continuing the devaftations they had been guilty of before they were put under his direction. Mythologifts explain the original of thefe fables, by faying, that he was a wife and good prince ; and, being ikilled in ailronomy, was able, by the flux and reflux of the tides, and the nature of the volcano in the ifland Strongyle, to foretel ftorms and tempefts.

Eon, among the followers of Plato, was ufed to fignify any virtue, attribute, or perfedlion : hence they reprefented the deity as an afiemblage of all pof- fible sons; and called him pleroma, a Greek term fignifying fullnefs. The Valentinians, who, in the firft ages of the church, blended the conceits of the Jewifh cabalifts, the Platonifts, and the Chaldean philofophers, v/ith the fimplicity of the Chriftian dodrine, invented a kind of Theogony, or Genealogy of Gods (not un¬ like that of Hefiod), whom they called by feveral glo¬ rious names, and all by the general appellation of Eons: among which they reckoned L**,Life; Ao/if, Word; Movofunc, Only-begotten; Fullnefs; and many other divine powers and emanations, amounting in -ffioiij ./Eon. jE R A [ 143 ] A £ R ' JEora fn number to thirty: which they fancied to be fuc- U ceffively derived from one another; and all from one , felf-originated deity, named Bythus, i. e. profound or unfathomable; whom they called likewife, The mojl high and ineffable-Father. See Valentinians. iEORA, among ancient writers on medicine, is ufed for geftation ; which fort of exercife was often preferib- ed by the phyficians of thofe days. Other exercifes confuted principally in the motion of the body; but in the which would inllantly ceafe in vacuo. Thus g oils and falts, which remain united in air, feparate as Elaftkity of foon as that fluid is extrafted. Hence alfo, when hot the air.. water is put under an exhaufted receiver, it boils violent¬ ly ; becaufe the preflure of the air being now taken off, the particles of fleam, which exifted invifibly among the water, and which the gravity of the atmofphere prevented from flying off fo foon, are now hurried up with great velocity, by means of the excefilve compa¬ rative gravity of the aqueous fluid. On the gravity of the air depend the afeent of wa¬ ter in pumps, fyphons, &c. and likewife all the pheno- « nomena of the barometer. . Befldes its gravity, which the air has in common with water and other fluids, there is another which it has only in common with fleam or vapour. This is called its elajiicity; by which, like a fpring, it allows itfelf to be compreffed into a fmaller bulk, and then re¬ turns again to its original flze upon removing thepref- fure. The elafticity of the air was firfl afeertained by fome experiments of lord Bacon, who, upon this principle, conftrufted the firft thermometer, which he called his vitruin calendare. Of this power we have numerous proofs. Thus, a blown bladder being fqueezed in the hand, we find the included air fenfibly refift ; fo that, upon ceafing to comprefs, the cavities or impreffions made in its furface are readily expanded again and fill¬ ed up. The flrufture and office of the y&V-PuMP depend on this elaftic property. Every particle of air always exerts a nifus or endeavour to expand, and thus ftrives againft an equal endeavour of the ambient particles ; whofe refiftance happening by any means to be weak¬ ened, it immediately diffufes itfelf into an immenfe ex. tent. Hence it is that thin glafs bubbles, or bladders filled with air, and exactly clofed, being included in the exhaufted receiver of an air-pump, burft by the force of the air they contain; and a bladder almoft quite flaccid, fwells in the receiver and appears full. The fame effeft alfo takes place, though in a fmaller degree, on carrying the flaccid bladder to the top of an high ^ mountain. Whether It has been queftioned among philofbphers, whether this proper- this elaftic power of the air is capable of being deftroy- duninijhed e<^ or diminifhed. Mr Boyle made feveral experiments ' with a view to difeover how long air would retain its fpring after having affumed the greateft degree of ex- panfion his air-pump would give it; but he was never able to obferve any fenfible diminution. Defaguliers found, that air, after having been inclofed for half a year in a wind-gun, had loft none of its elafticity; and Roberval, after preferving it in the fame manner for 16 years, obferved, that its expanfive projectile force was the fame as if it had been recently condenfed.. Neverthelefs, Mr Hauklbee concludes, from a later ex¬ periment, that the fpring of the air may be difturbed by a violent preffure, in fuch a manner as to require fome time to return to its natural tone. Dr Hales in¬ ferred, from a number of experiments, that the elafti¬ city of the air is capable of being impaired and dimi- niftied by a variety of caufes. The weight or preffure of the air has no dependence on its dafticity ; but would be the fame whether it had 3;.. LOGY. Sed. I. fuch a property or not. The air, however, being e- Of Air laftic, is neceffarily affetted by the preffure, which re- *n £tnera^ duces it into fuch a fpace, that the elafticity, which re- ' v' * ads againft the compreffing weight, is equal to that weight. In effed, the law of this elafticity is, that it increafes as the denfity of the air increafes ; and the denfity increafes as the force increafes by which it is preffed. Now there muft neceffarily be a balance be¬ tween the adion and re-adion; i. e. the gravity of the air which tends to comprefs it, and the elafticity by which it endeavours to expand, muft be equal. Hence the elafticity increafing, or diminifliing univerfally, aa the denfity increafes or diminiflies, it is no matter whe¬ ther the air be compreffed and retained in fuch a fpace by the weight of the atmofphere, or by any other means ; it muft endeavour in either cafe to expand with the fame force. And hence,, if air near the earth be pent up in a veffel, and all communication with the external fluid cut off, the preffure of the inclofed air will be equal to the weight of the atmofphere at the time the quantity was confined. Accordingly, we find mercury fuftained to the fame height,, by the elaftic force of air inclofed in a glafs veffel, as by the whole atmofpherical preffure. On the fame principle air may be artificially condenfed; and hence the ftrudure of the Air-G««. ict The utmoft limits to which air, of the denfity which Utmoft li¬ lt poffeffes at the furface of the earth, is capable of be- nuts of its mg compreffed, have not been afeertained. Mr Boyle made it i 3 times more denfe ; Dr Halley fays that he ‘ anj-lon> has feen it compreffed fo as to be 60 times denfer than in its natural ftate, which is farther confirmed by M. Papin and M. Huygens. Dr Hales, by means of a prefs, condenfed it 38 times ; and by forcing water in an iron ball or globe, into 1551 times lefs fpace than it naturally occupies. However, Dr Halley has af- ferted, in the Philofophical Tranfa&ions, Abr. vol. ii. p. 17. that from the experiments made at London, and by the academy del Cimento at Florence, it might be fafely concluded, that no force whatever is able to re¬ duce air into 800 times lefs fpace than that which it naturally poffeffes on the furface of our earth. In an- fwer to this, M. Amontons, in the Memoirs of the French Academy, maintains, that there is no fixing any bounds to its condenfation; that greater and great¬ er weights will ftill reduce it into lefs and lefs compafs; that it is only elaftic in virtue of the fire which it con¬ tains ; and that as it is imppffible ever to drive all the fire out of it, it is impoffible ever to make the utmoft condenfation. The dilatation of the air, by virtue of its elaftic force, is found to be very furprifing ; and yet Dr Wallis fug- gefts, that we are far from knowing the utmoft of which it is capable. In feveral experiments made by Mr Boyle, it dilated firft into nine times its former fpace ; then ihto 31 times ; then into 60 ; then into 15a. Afterwards it was brought to dilate into 8000 times- its fpace, then into 10,000,. and even at laft into 13,679 , times its fpace ; and this altogether by its owm expan¬ five force, without the help of fire. On this depend the ftru&ure and ufe of the Manometer. Hence it appears, that the air we breathe near the furface of the earth is compreffed by its own weight into at leaft the 13,679th part of the fpace it would poffefs in vacuo. But'if the fame air be copdenfed by att, Sed. I. Of Air In general. Expanfion «f the air by heat. 12 General ef feifcs of the air’s elafti- city. AERO art, the fpace it will take up when moft dilated, to that it pofiefles when condenfed, will be, according to the fame author’s experiments, as 550,000 to 1. M. Amontons, and others, we have already ob- ferved, attribute the rarefa&ion of the air wholly to the lire contained in it; and therefore, by irtcreafing the degree of heat, the degree of rarefadtion may be carried Hill farther than its fpontaneous dilatation. Air is expanded one-third of its bulk by boiling water. Dr Hales found, that the air in a retort, when the bottom of the veffel was juft beginning to be red-hot, was expanded through twice its former fpace ; and in a white, or almoft melting heat, it occupied thrice its former fpace ; but Mr Robins found it was expanded by the heat of iron, juft beginning to be white, to four times its former bulk. On this principle depend the ftrufture and office of the Thermometer.. M. Amontons firft difcovered that air will expand in proportion to its denfity with the fame degree of heat. On this foundation the ingenious author has a difcourfe, to prove “ that the fpring and weight of the air, with a moderate degree of warmth, may en¬ able it to produce even earthquakes, and other of the moft vehement commotions of nature.” See the ar¬ ticle EARTHqUAKE. . The elaftic power of the air, then, is the fecond great fource of the effefts of this important fluid. Thus it infi- nuates into the pores of bodies; and, by poffeffing this prodigious faculty of expanding, which is fo eafily ex¬ cited, it muft neceflarily put the particles of bodies into which it infmuates itfelf into perpetual ofcillations. Indeed, the degree of heat, and the air’s gravity and denlxty, and confequently its elafticity and expanfion, never remaining the fame for the leaft fpace of time, there muft be an inceffant vibration or dilatation and contrattion in all bodies. We obferve this reciprocation in feveral inftances, particularly in plants, the air-veffels of which do the office of lungs ; for the contained air alternately ex¬ panding and contrafting, according to the increafe or diminution of the heat, alternately prefles the veffels and eafes them again, thus keeping up a perpetual motion in their juices. Hence we find, that no vegetation or germination will proceed in vacuo. Indeed, beans have been ob- ferved to grow a little tumid therein ; and this has led fome to attribute that to vegetation which was really owing to no other caufe than the dilatation of the air within them. The air is very inftrumental in the pro- duftion and growth of vegetables, not only by invigo¬ rating their feveral juices while in an elaftic aftive ftate, but alfo by greatly contributing in a fixed ftate to the union and firm connexion of their feveral conftituent parts. From the fame caufe it is, that the air contained in bubbles of ice, by its continual action burfts the ice. Thus a’fo, entire columns of marble fometimes cleave in the winter time, from the increafed elafticity of fome little bubble of air contained in them. From the fame principle arife all putrefaiition and fermentation ; nei¬ ther of which will proceed, even in the beft difpofed fubjefts, in vacuo. Since we find fuch great quantities of elaftic air ge¬ nerated in the folution of animal and vegetable fub- ftances, a good deal muft conftantly arife from .the dif- LOGY. 147 folution of thefe aliments in the ftomach and bowels, _ Of Air which is much promoted by it; and, in reality, all in generaI- natural corruption and alteration feem to depend on v '' air. $ 3. Effetts of the different Ingredients of Air.— This fluid a£ts not only by its common properties of gravity and elafticity, but produces numerous other ef- fedts arifing from the peculiar ingredients of which it confifts. 13 Thus, 1. It not only diffolves and attenuates bodies Solvent by its preflure and attrition, but as a chaos containing ^ all kinds of menftrua, and confequently poffeffing pow- metais- ers for diflblving all bodies. It is known that iron and copper readily diflblve and become rufty in air, un- lefs well defended with oil. Boerhaave aflures us, that he has feen pillars of iron fo reduced by air, that they might be crumbled to dull between the fingers; and as for copper, it is converted by the air into a fubftance much like the verdigrife produced by vinegar. Mr Boyle relates, that in the fouthern Englifh co¬ lonies the great guns ruft fo faft, that after lying in the air for a few years, large cakes of crocus martis may be feparated from them. Acofta adds, that in Peru the air difiblves lead, and confiderably increafcs its weight. Yet gold is generally efteemed indiflbluble by air, being never found to contraft ruft, though ex- pofed to it ever fo long. In the laboratories of che- mifts, however, where aqua regia is prepared, the air becoming impregnated with a quantity of the vapour of this menftruum, gold contrails a ruft like other bodies. T4 Stones alfo undergo the changes incident to metals. On Hones. Thus Purbeck ftone, of which Salilbury cathedral con¬ fifts, is obferved gradually to become fofter, and to moulder away in the air; and Mr Boyle gives the fame account of Blackington ftone. He adds, that air may have a confiderable operation on vitriol, even when a ftrong fire could ail no farther upbn it. And he has found, that the fumes of a corrofive liquor work more fuddenly and manifeftly on a certain metal when fuf- tained in the air, than the menftruum itfelf did, which emitted fumes on thofe parts of the metal which it co¬ vered ; referring to the effeils of the effluvia of vine¬ gar on copper. The diffblving power of air is increafed by heat, and by other caufes. It combines with water; and by ac- cefs of cold, depofites part of the matter which was kept diflblved in it by a greater degree of heat. Hence the water, by being depofited and condenfed upon any cold body, fuch as glafs, &c. in windows, forms fogs, and becomes vifible. Ty In the various operations of chemiftry, air is a very Various neceffary and important agent; the refidt of particular chemical proceffes depending on its prefence or abfence, on its e,ffe*s being open or inclofed. Thus, the parts of animals air' and vegetables can only be calcined in open air ; in clofe veflels they never become any other than black coals. And thefe operations are affecled by the changes to which the air is liable. Many inftances might be adduced to this purpofe. Let it fuffice to obferve, that it is very difficult to procure oil of fiilphur, per campanam, in a clear dry atmofphere ; but in a thick moift air it may be obtained with greater eafe, and in larger quantities. So, pure weR-fermented wine, if it be carried to a place where the air is repleniftied with T 2 the 148 AERO Of Aii* the fumes of new wine then fermenting, will begin to in general. ferment afreftu v The changes in the air arife from various caufes, and are obfervable, not only in its mechanical proper¬ ties, fuch as gravity, denfity, &c. but in the ingredients that compofe it. Thus, at Fafhlun in Sweden, noted for copper-mines, the mineral exhalations affe& the air in fuch a manner as to difcolour the fiber coin in purfes; and the fame effluvia change the colour of brafs. In Carniola, Campania, &c. where are mines of fulphur, the air fometimes becomes very unwholefome, which occafions frequent epidemic difeafes, &c. The effluvia of animals alfo have their effeft in vary¬ ing the air; as is evident in contagious difeafes, plagues, murrains, and other mortalities, which are fpread by an infefted air.

Hijlorkal Account of the principal Dif- coveries concerning the Compofition of Atmofphe- rical Air and other Aerial Fluids- While the preceding difcoveries were making con¬ cerning the mechanical and other properties of the air, little notice feems to have been taken of the elementa¬ ry parts of the air itfelf, or the different kinds of fluid which go under that name. It was known, indeed, that air was feparable from terreftrial bodies by means of fire, fermentation, &c. but this was commonly rec- 16 koned to be the fame with what we breathe. Van Van Hel- Helmont, a difciple of Paracelfus, was the firft who fwTdifco undertook to make inquiries concerning this fpecies of verer ofdFf- air- He gave it the name of gasfykejlre, from the ferent kinds.Dutch word ghoafl, fignifying fpirit; and obferves, that ah. fome bodies refolve themfelves almoft entirely into it. “ Not (fays he) that it had been aftuaHy contained in that form in the bodies from which it was feparated; but it was contained under a concrete form, as if fixed, or coagulated.” According to this author, the gas fylveftre is the fame with what is feparated from all fubftances by fermentation ; from vegetables by the aftion of fire ; from gun-powder when it explodes; and from charcoal when burning. On this occafion he afferts, that 62 pounds of charcoal contain 61 pounds of gas and only one pound of earth. To the efflu¬ vium of gas he alfo attributes the fatal effetts of the grotto del Cani in Italy, and the fuffocation of work¬ men in mines. Fie afferts,- that it is to the corruption of the aliment, and the gas difeharged from it, that we are to attribute wind, and the difeharges of it from the bowels. Upon the fame principles he accounts for the fwelihig of dead bodies which have remained for a time under water, and for the tumours which arife on fome parts of the body in certain difeafes. He alfo determines,, that this gas is different from the air we breathe; that it has a greater affinity with water: and he imagined it might confift of water reduced to vapours, or a very fubtile acid combined with volatile 27 alkali. Difcoveries Mr Boyle repeated all Van Helmont’s experiments by Mr to more advantage than he himfelf had performed them; Seylp, but feems not to have proceeded further in his difco¬ veries than Van Helmont did: only he found fome bodies, fuch as fulphur, amber, camphor, See. dimi- aiili the volume of air in which they burn. L O G Y. Sedt. II, Dr Hales firft attempted to determine the quantity Of Air of air produced from different bodies ; for which pur- in general, pofe he made experiments on almoft every known fub- v '* ftance in nature, examining them by diftillation, fer- I mentation, combuftion, combinations, &c. He alfo jp863 j firft fufpefted, that the briflenefs and fparkling of the Snfpicion of ■ i waters, called acidulous, were owing to the air theyair m mine- ;j| contained. But notwithftanding all his difcoveries con- ra' waters* | cerning the quantity of elaftic fluid obtained from dif¬ ferent bodies, he did not imagine there was any effen- tial difference between this fluid and the air we breathe} il only that the former was loaded with noxious vapours, foreign to its nature. His fufpicion concerning this impregnation was confirmed by M. Vend, profeffor of Confirmed ^ chemiftry at Montpelier, in a memoir read before the! y Mr Vo- ] Royal Academy of Sciences in 1750. This gentle-,lel* man was able to difengage the air from the Seltzer waters, and to meafure its quantity ; which he con- ftantly found to amount to about one-fifth of its bulk. The water thus deprived of its air became flat, and ceafed to fparkle ; the only difference then betwixt it and common water was, that the former contained a fmall quantity of fea-falt. Upon thefe principles he attempted to recompofe Seltzer water, by diffolving in a pint of common water two drachms of foffile alkali, and then adding an equal quantity of marine acid. The quantity of fea-falt produced by the union of thefe two, he knew would prove equal to that contain¬ ed in a pint of Seltzer water; and the effervefcence produced by the action of the acid and alkali upon each other, he imagined, would produce air fufficient for the impregnation of the water. In this he was not deceived; the water thus produced was not only analogous to Seltzer, but much more ftrongly impreg¬ nated with air. Dr Black firft difeovered, that chalk, and the other D;fCOV(.r;f3. earths reducible to quicklime by calcination, confift ofbyDrBlack, an alkaline earth, by itfelf foluble in water, but which, &c. combined with a large quantity of fixed air, becomes infoluble; lofing the properties of quicklime, and af- fuming the natural appearance we obferve thofe earths to have when not reduced into lime. The fame thing he difeovered in magnefia alba, and in alkalis both fixed and volatile. On the fixed air contained in thefe bodies, he found not only their property of effervef- cing with acids to depend, but likewife their milunefs ; both the alkalis and calcareous earth being highly cauftic when deprived of their fixed air. He alfo found, that this fluid, which he called fxed air, had different degrees of affinity with different fubftances; that it was ftronger with calcareous earth than with fixed al¬ kali ; with fixed alkali, than magnefia; and with mag¬ nefia, than volatile alkali.. He alfo fufpedted, that the fixed air of alkaline falts unites itfelf with the precipi¬ tates of metal's, when thrown down from acids; and that the increafe of weight obfervable in thefe precipi¬ tates was owing to this caufe. But he was of opinion, that the fluid which he called fxed air was very diffe¬ rent from, the common air we breathe ; and therefore adopted the name of air, merely as one already efta- bliffied, whatever impropriety there might be in the term. It was not long before the difeovery of this fpecies of air fuggefted new theories in phyfiology and natural philofophy. Mr Haller had inferred, from Dr Hales’s experiments,. Sea. IT. AERO . Air experiments, that air is the real cement of bodies 5 in general. wh;c}1} fixJng hfelf in the folids and fluids, unites them ^ * to each other, and ferves as a bond by which they are kept from diffolution. In 1764, Dr Macbride of Dublin publilhed a number of experiments in fupport of this doftrine. From his work it appears, that fixed air is feparated, not only from all fubftances in fermen- tion, but alfo from all animal fubftances as they begin to putrefy; and that this air is capable of uniting it- felf to all calcareous earths, as well as alkalis both fixed and volatile, and reftoring to them the property of ef- fervefcing with acids when they have by any means been deprived of it. But though thefe opinions have fince been found erroneous, the concluixons drawn by him from his numerous, experiments ftill hold good, viz. that fixed air is an elaftic fluid, very different from the common air we breathe : that it is poffeffed of a ftrong antifeptic quality, and may be introduced with fafety into the inteftinal canal, and other parts of the animal ceconomy, where common air would have fatal 24 effefts ; but is mortal if breathed into the lungs, &c. Quantity of Fn 1766 and 1767, Mr Cavendifh communicated fixed air fome new experiments to the Royal Society at Lon- ■^"Ikali 'e ^on’ wherein he determines the quantity of air con- falts deter- ta^ne(i *n ^xed alkali, when fully faturated with it, to mined by be five-twelfths of its weight, and feven-twelfths in vo- Mr Caven- latile alkali: that water is capable of abforbing more difh. than its own bulk of this air; that it has then an agree¬ able, fpirituous, and acidulous tafte ; and that it has the property of diffolving calcareous earths and magnefia, as well as alpioft all the metals, efpecially iron and zinc : that the vapour of burning charcoal occafions a remark¬ able diminution of common air, at the fame time that a confiderable quantity of fixed air is produced in the operation. He alfo found, that folution of copper in fpirit of fait, inftead of producing inflammable air, like that of iron or zinc, afforded a fpecies of air which loft its elafticity as foon as it came into contact a3 with water. Conteft The difcoveries of Dr Black concerning fixed air concerning had not been long publilhed, when they were violently offixecUii-6 attac^efi by fome foreign chemifts, while his caufe was ' as eagerly efpoufed by others. The principal oppo¬ nents were Mr Meyer apothecary at Ofnabruck, Mr Crcfns phyfician to his Ruffian Majefty, and Mr de Smeth at Utrecht. Their arguments, however, were effectually anfwered at the time by Mr Jacquin, bota¬ nical profeffor at Vienna ; and the numerous difcove¬ ries made fince that time have given fuch additional confirmation to his dodtrine, that it is now univerfally adopted by chemifts both in Britain and other coun- Z4 tries. It was referved, however, for Dr Priejlley to Comped- make the great difeovery concerning the nature of our tion of the atmofphere ; and to inform the world, that it is com- Hftovered6 P°^e<^ two > the one abfolutely noxious, and incapable of fupporting animal life for a moment ; the other extremely falutary, and capable of preferring animals alive and healthy for a much longer time than the pureft air we can meet with. This may be confi- dered as the ultimate period of our hiftory : for fince that time the difcoveries of philofophers ftill living, in many different countries, have been fo rapid, that it. is difficult to afeertain the dates of them by any authentic documents; efpecially as, by reafon of fuch numerous experiments, the fame things have not unfrequently LOGY. 149 been difeovered by different perfons unknown to each Dephlogif- other. We Ihall therefore proceed to give an account t»cate u.. of the different kinds of aerial fluids, beginning with thofe which are known, or fuppofed, to conftitute a part of our atmofphere. Sect. III. Gf Dephlogijlicated Air. § X. Difeovery ard Methods of procuring this Kind of Air.—Dephlogifticated air was firft obtained by Dr Prieftley on the ift of Auguft 1774. The circumftan ! ces which led him to the difeovery, were his having always procured inflammable air from fpirit of fait, by adding to it fpirit of wine, oil of olives, oil of turpen¬ tine, charcoal, phofphorus, bees wax, and even fulphur. Hence he fufpe&ed, that the common air wre breathe ,ir might be compofed of fome kind of acid united with whence phlogifton. On this fuppofition he extracted air from firft extrac- mercurius calcinatus per fe, by expofing it to the focus te^‘ of a burning-glafs 12 inches in diameter ; and, having repeated the experiment with red precipitate and mini¬ um, he found, that though a quantity of fixed air was always produced, yet after that was feparated, the re¬ mainder fupported flame much more vigoroufly than common air; for a candle burned in it with a flame very much enlarged, and with a crackling noife, at the fame time that it appeared fully as much diminiih- ed by the tell of nitrous air.. Whence he concluded, that it was refpirable; and, on making the experiment, found that it actually was fo, for a moufe lived a full half hour in a quantity of this fluid; which, had it been common air, would only have kept it alive half that time. Nor did the animal feem to be otherwife injured than by the cold; as it prefently revived on bringing it near the fire, and the remainder of the air ftill ap¬ peared better than that of the atmofphere, when the tell of nitrous air was applied to it. ^ This pure kind of air being difeovered, the Do&or whynamed next proceeded to name it dephlogificated, from hisdephls-gifti- opinion that common air, in the aft of burning, ab- forbed phlogifton ; of confequence, he fuppofed, that which abforbed the moll, or which moft vigoroufly and for the greateft length of time fupported flame, was fuppofed to contain the fmalleft quantity of this fub- ftance. In the courfe of his inquiries why this kind of air comes to be fo much dephlogifticated, he fell upon a method of extracting it from a great variety of fub¬ ftances ; viz. by moiftening them with fpirit of nitre, and produced then diftilling them, with a ftrong heat. Thus he ob-fromagrea^ tained it from flowers of zinc, chalk, quicklime, flacked variety of lime, tobacco-pipe clay, flint, Mufcovy talcs, and even fu^^ancC5, glafs. He then found, that by Amply diffolving any metal in the nitrous acid, and then diftilling the folu¬ tion, he could obtain very pure air: and Mr Warltire found even the trouble of diftillation unneceffary; no¬ thing more being requifite than to moiften red lead with the fpirit of nitre, and then pour upon it the oil of vitriol, which inftantly difengap-ed the dephlogifti¬ cated air without applying any more heat than what was generated by the mixture. 2g While difcoveries of thiskind engaged Dr Prieftley in This kind England,. Mr Scheele was employed in a fimilar man- of ™ dif- ner in Sweden; and had actually obtained the fame ^ov"e<^ 3®*s kind of air, without knowing any thing of what Dx slheeL Prieftley had done. The latter had the merit of the prior 150 AERO Deplilogif- prior difcovery: but Mr Scheele’s method was more t cated Air. confifting only in the diftillation of nitre with a ftrong heat; by which means it is now found that dephlogifticated air may be obtained in very confider- able quantity, and in as great purity, as by the ■ more expenfive procefles. The pure air from nitre had in¬ deed partly been obtained, by Dr Hales long before this time; fince he informs us, that half a cubic inch of nitre yielded 90 cubic inches of air, which was un¬ doubtedly the fluid we fpeak of; but as he negledied to profecute the difcoveiy, nothing farther was known 29 at that time. May be As the nitrous acid was univerfally concerned in the produced firlt procefles for obtaining this kind of air, it was for wnhoutni-w t;me generally believed to be a peculiar pro- . rous aci perty 0f that acid alone to produce it; but the in¬ defatigable genius of Dr Prieftley foon found, that it might not only be procured where no nitrous acid was employed, but where the fubftances were treated with vitriolic acid. It was indeed evident, from the very firft experiment, that nitrous acid was not eflentially neceflary ; fmee pure air was procured from precipitate per fe, in the preparation of which no nitrous acid is employed. The Abbe Fontana found, that 192 grains of this fubftance yielded 26^ cubic inches of dephlogi- flicated air, at the fame time that the weight of it was reduced to 178^- grains, which is nearly the weight of that quantity of air. It had formerly been obferved, that the weight of mercury is augmented during its converfion into precipitate per fe, as that of lead is by its converfion into minium. The experiments juft now mentioned, therefore, fhow, that during this procefs the air is decompounded; the pure dephlogifticated part of it being abforbed by the metal, and appearing again on the application of heat; and the fame appears to be the cafe with red lead, from the experiment of Mr Warltire already mentioned. With regard to this laft fubftance, however, a very great Angularity is ob¬ ferved ; viz. that when newly prepared it yields none at all, and even for fome time after the produce is much fmaller than when it has been long kept. The reafon of this feems to be, that the minium ftill con¬ tains a confiderable quantity of phlogifton, which flies off into the atmofphere by long keeping, a larger quan¬ tity of the dephlogifticated part of the atmofphere be¬ ing imbibed at the fame time. The mode of applying t heat has alfo a very confiderable effect on the quantity and Obferv al'r Pro^uce^- Thus, Dr Prieftley remarks *, that lii. 37. li from equal quantities of red lead, without any mix- 30 ture of fpirit of nitre, and ufing the fame apparatus for Produced diftilling it, he obtained, by means of heat applied in greated fuddenly, more air than when flowly applied, in the byTquick proportion of ten to fix. The proportion of fixed air and violent was the fame in both cafes, and the remainder equally heat. dephlogifticated.” Method of ^ *ieat alone, the Doftor found, that fedative fait, extracting manganefe> lapis calaminaris, and the mineral called it from va-A/uV ponderofus, 'wolfram, or tungften, would yield de- rious fub- phlogifticated air ; the firft indeed in very fmall quan- .fiances. thy, and fometimes even of a quality very little fupe- •rior to common air. In thefe experiments, he made v ufe of fmall-bellied retorts of green glafs, which can ftand the fire beft, containing about an ounce of water, and having narrow necks 18 or 20 inches long. The fubftance to be examined was put into a retort of this LOGY. Setf.Iir, kind, and then expofed to a red heat, either in fand or Depblogif- over a naked fire, while the neck of the yeffel was treated. Air, plunged in water or mercury. ' ^ Having diffolved fix pennyweights of very clean iron in oil of vitriol, and then diftilled the folution to dry- nefs in a long-necked retort, he received the common air a little phlogifticated, fome fixed air, much vitrio¬ lic acid air, and laftly 18 ounce meafures of dephlo¬ gifticated air. The iron that remained undiffolved w eighed 23 grains, fo that the air was yielded by five pennyweights one grain of iron. The ochre weighed feven pennyweights thirteen grains: fo that, fays he, there probably remained a quantity of oil of vitriol in it; and confequenlly, had the heat been greater, more air would have been obtained. In his experiments with the nitrous acid, as it had conftantly been found, that by pouring on more nitrous acid on the refiduum, and repeating the operation, more dephlogifticated air might be obtained, the Doc¬ tor determined to try whether the fame would not hold good with vitriolic acid alfo. For this purpofe, he added more oil of vitriol to the refiduum of the laft- mentioned experiment. When in a red heat with a glafs retort, it yielded a quantity of vitriolic acid air, no fixed air, but about 24 ounce meafures of dephlogifti¬ cated air; when, the retort being melted, a good deal of the air was neceffarily loft ; but, on refuming the procefs in a gun-barrel, he procured as much air as had been got before.—Purfuing thefe experiments, he obtained with common cruft of iron and oil of vitriol, dephlogifticated air at the firft diftillation, and a great deal more from the refiduum, by pouring frefti oil of vitriol upon it. The fame product he obtained from blue vitriol, folution of copper in the vitriolic acid, and from a folution of mercury in that acid. On this fubftance he remarks, that “ either by means of oil of vitriol or fpirit of nitre, it yields a great quantity of dephlogifticated air : but with this difference, that in the procefs with fpirit of nitre, almoft the whole of the mercury is revived (not more than a twentieth part being loft, if the procefs be conducted with care); but in that with vitriolic acid, almoft the whole is loft.” From the later experiments of Mr Lavoifier, however, it appears that the Doftor’s procefs had not been con¬ ducted with fufficient care ; as from two ounces of the dry fait formed by a combination of vitriolic acid with mercury, the former obtained 6 drachms 12 grains of running mercury, befides 3 drachms 58 grains of mer¬ curial fublimate of two different colours. Dephlogi¬ fticated air was like wife obtained from pure calx of tin, or putty, mixed with oil of vitriol; but none in any trial with the marine acid, excepting when it was mixed with minium; in which cafe the air obtained was probably that which the minium would have yielded without any addition. The refult of all thefe, and innumerable other experi¬ ments made by philofophers in different countries, was, that dephlogifticated air may be obtained from a vaft variety of mineral and metallic fubftances by means of the vitriolic and nitrous acids. It now remained onljtHow to difeover in what manner this fluid, fo effentially ne- phlogifti- ceffary to the fupport of animal life, is naturally pro- cated air is duced in quantities fufficient for the great cxpence of natu.ra^y it throughout the whole world, by the breathing of a- uce nimals, the fupport of fires, &c. This difeovery, irf- deed. Sea, III. AERO Dephlogif- deed, had been made before even the exiftence of de- ticated'Air. phlogifticated air itfelf was known. Dr Prieftley, af- y ter having tried various methods of purifying contami¬ nated air unfuccefsfully, found at Jaft, that fome kinds of vegetables anfwered this purpofe. very effe&ually ; for which difcoveryhe received the thanks of the Royal Society. Among the vegetables employed on this oc- cafiori, he found mint anfwer the purpofe very effectu- * Evper. ally. “ When air,” fays he*, “ has been freflily and and Obferv. ftrongly tainted with putrefaflion, fo as to fmell vol.i.p. i. through the water, fprigsof mint have prefently died c ,4' upon being put into it, their leaves turning black ; but if they do not die prefently, they thrive on a moft fur- prifing manner. In no other circumllances have I feen vegetation fo vigorous as in this kind of air, which is immediately fatal to animal life. Though thefe plants have been crowded in jars filled with this kind of air, every leaf has been full of life; freflr Ihoots have branched out in various directions, and grown much 3, fafter than other fimilar plants growing in the fame ex- Noxious air pofure in common air.”—Having in confequence of improved this obfervation rendered a quantity of air thoroughly by vegeta- noxious, by mice breathing and dying in it, he divided ting mint. ^ jnto two rece;vers inverted in water, introducing a fprig of mint into one of them, and keeping the other receiver unaltered. About eight or nine days after, he found that the air of the receiver into which he had introduced the fprig had become refpirable; for a moufe lived very well in this, whereas it died the moment it was put into the other. Experi- From thefe' experiments the Do&or at firft conclu- mentsfeem- ded, that in all cafes the air was meliorated by the ve- ingly con- getation of plants : but even in his firil volume he ob- tradiu 01 y. perveSj fome experiments of this kind did not an¬ fwer fo well towards the end of the year as they had done in the hot feafon; and a fecond courfe feemed to be almoft entirely contrary to the former. Having tried the power of feveral forts of vegetables upon air infe&ed by refpiration or by the burning of candles, he found that it was generally rendered worfe by their vegetation; and the longer the plants were kept in the mfeCted air, the more they phlogifticated it; though ' in feveral cafes it was undoubtedly meliorated, efpeci- ciaHy by the Ihoots of ftrawberries and fome other plants, introduced into the vials containing foul air, • and inverted in water,- which were placed near them, whiift their roots continued in the earth in the garden. Sometimes the infeded air was fo far mended by the vegetation of plants, that it was in a great meafure turned into dephlogifticated air. “ On the whole,” * Exper. fayS J)r Prieftley, “ I ftill think it probable, that the f"d ^)*erv-vegetation of healthy plants, growing in fituations na¬ tural to them, have a falutary effect on the air in which they grow.—For one inftance of the melioration of air in thefe circumftahces fhould weigh againft an hundred, in which the air is made worfe by it, both on account of the difadvantages under which all plants labour, in the circumftances in which thefe experiments muft be made, as well as the great attention and many precau¬ tions that are requifite in conducing fuch a prccefs.” At the time that Dr Prieftley made thefe experi¬ ments, he fuppofed that the air was meliorated merely Experi¬ ments of Dr Ingen- houfzon the by the abforption of phlogifton from that which had melioration been tainted ; but the experiments of Dr Ingenhoufz, vegetation ma(^e l779> ffowed that this was accomplilhed, not L O G Y. 151 only by the abforption juft mentioned, but by the emif- Dephlogif- fion of dephlogifticated air. He obferved in general, betted Air- that plants have a power of correcting bad air, and 7 even of improving common air in a few hours, when expofed to the light of the fun ; but, in the night-time, or when they arc not influenced by the folar rays, they contaminate the air. This property, however, does not belong in an equal degree to all kinds of plants : nor is it poffible to difeover by the external properties of a plant, whether it be fit for this purpofe or not; as fome w’hich have a bad fmell, and are entirely unfit for food, fhow themfelves much fuperior to others whofe external appearance would feem preferable. His me¬ thod of making the experiment was, to fill a vial with air, fouled either by refpiration or combuftion ; after which a fprig of any plant was introduced, by paffrng it through the water in which the vial was immerfed. The vial was then flopped ; or it was removed into a fmall bafon full of water, and expofed to the fun, or fi- tuated in feme other proper place as occafion required, . Air phlogifticated by breathing, and in which a candle could not burn, after being expofed to the fun for three hours, with a fprig of peppermint in it, was fo far cor¬ rected, as to be again capable of fupporting flame. The following experiment, however, made with a mu- ftard plant, may be looked upon as decifive : A plant of this kind was put into a glafs receiver containing common air, and its ftem cut off even with the mouth of the receiver. The veffel was then inverted in an earthen pan, containing fouK water to keep the plant alive, and the whole apparatus was fet over-night in a room. Next morning the air was found fo much con¬ taminated, that it extinguifhed the flame of a wax ta¬ per. On expofing the apparatus to the fun for a quar¬ ter of an hour, the air was found to be fomewhat cor- recled ; and after an hour and an half it was fo far im¬ proved, that by the teft of nitrous air it appeared con- fiderably better than common air. Before we proceed farther in the account of Dr In-Dephlo- genhoufz’s experiments, it will be neceffary to relate gifacated fome obfervations made by Dr Prieftley ; from which it appears, that dephlogifticated air, in very confider-water' able quantity, may, in certain circumftances, be pro¬ cured from water alone. The fubftance of thefe is, that water, efpecially pump-water, when expofed to the light of the fun, emits air flowly : but after fome time a green matter appears on the bottom and fides of the glafs ; after which it emits very pure air in great quan¬ tity, and continues to do fo for a very long time, even ; after the green matter has Ihown fome fymptoms of de¬ cay by becoming yellow. He obferved, that the water which naturally contained the greateft quantity of fix- . ed air, yielded alfo the greateft quantity of that which was dephlogifticated ; but that the quantity of the lat¬ ter much exceeded that of the fixed air contained even in any water. The light of the fun was found to be an , effential requifite in the formation of this air, as very little, and that of a much worfe quality, was produced in the dark. As the green matter produced in Dr Prieftley’s glaf- fes, was by himfelf, as well as others, confidered as be- longing to the vegetable kingdom. Dr Ingenhoufz im¬ proved upon his procefs, by putting the leaves of plants 37 r into water, and expofing them to the fun. All plants * £e were not equally fit for producing dephlogifticated air p^nts.0 by. 152 AERO Dephlogif- by this method more than by the other. Some poifoaons ticated Air, pjaijts> as the hyofcyamus, lauro-cerafus, night-ihade, v"_"" the tobacco-plant, a triplex vulvaria, cicuta aquatica, and fabina, were found very fit for the purpofe ; but the pureft kind of air was extra&ed from fome aquatic vegetables, the turpentine-trees, and efpecially from the green matter he collefted in a ftone trough which was kept continually filled with water from a fpring near the high-road. The purity of this dephlogifticated air, he fays, was equal, if not fuperior, to that procured by the beft chemical proceffes ; as it fometimes required eight times its own quantity of nitrous air to faturate it. All parts of the plants were not found equally pro¬ per for the production of dephlogifticated air; the full grown leaves yielded it in greateft quantity and puri¬ ty, efpecially from their under furface. It was alfo procured from the green ftalks.— One hundred leaves of Naflurtium Indicum, put into a jar holding a gallon, •filled with ordinary pump-water, and expofed to the fun from i o to 12 o’clock, yielded as much air as filled a cylinderical jar four inches and an half in length, and ■one and three quarters in breadth. On removing this •quantity of air, and expofing them again to the fun till feven o’clock, about half as much was produced, of a quality ftill fuperior to the former; and next morning by eleven o’clock, they yielded as much more of an equal quality. The roots of plants, he fays, when kept out of ground, generally yield bad air, and at all times contaminate common air, a few only excepted. Flowers and fruits, in general, yield a very fmall quantity of noxious air, and contaminate a great quantity of com¬ mon air at all times, efpecially in the night, and when kept in the dark. Two dozen of young and fmall French beans, kept in a quart-jar of common air for a Jingle night, contaminated the air to fuch a degree, that a very lively chicken died by being confined in it lefs g than half a minute. Conclufions The obfervations of Dr Ingenhoufz on the whole, from Dr fays Mr Cavallo, clearly (how, “ that the vegetation houfz’s ex P^ants 18 one t^e great means employed by nature fieriments" t0 PurTy ^e atmofphere, fo as to counteract:, in great meafure, the damage done by animal refpiration, com- buftion, &c. It may only be faid, that vegetation does not appear t@ be fufficient to remedy entirely that damage.” The Doctor himfelf, however, fpeaks very highly of the powers of vegetables in this refpect. He informs us, that their office in yielding dephlogifticated air begins a few hours after the fun has made his ap¬ pearance in the horizon, or rather after it has pafied the meridian, and ceafes wfith the clofe of day ; except¬ ing fome plants which continue it a fhort time after fun- fet: The quantity of dephlogifticated air, yielded by plants in general, is greater in a clear day than when it is fomewhat cloudy. It is alfo greater when the plants are more expofed to the fun, than when they are fitua- ted in fhady places. He obferves, moreover, that the damage done by plants in the night, is more than coun¬ terbalanced by the benefit they afford in the day-time. “ By a rough calculation, (fays he), I found the poi- fonous air, yielded by any plant during the whole night, could not amount to onehundredth part of the dephlogif¬ ticated air which the fame plant yielded in two hours time in a fair day.”—It does not appear, however, that plants yield dephlogifticated air by any kind of 'gene¬ ration of that fluid, but only by filtrating the common N°4. LOGY. Sea. III. air, which all plants abforb through their pores j the Dephkg-if- ej phlogiftic part becoming part of their fubftance, and ^cated Air; probably being the true vegetable food, as is explain- v" ed more at large under the article Agriculture. — Dry plants have little or no effeft upon the air until they are moiftened —On all thefe experiments, how¬ ever, it muft be obferved, that they have fometimes failed in the hands of thofe whom we cannot but fup- pofe very capable of trying them ; as Mr Scheele, Mr Cavallo, and the Abbe Fontana. 39 After the publication of Dr Ingenhoufz’s experi-Sir benja- | ments, it became generally believed, that the atmof- j phere was meliorated by the common procefs of vege- riments. tation, and that plants abforbed the phlogiftic part as their food, difcharging the pure dephlogifticated air as an excrement; which is juft the reverfe of what hap¬ pens to animals, who abforb the pure part in refpira¬ tion, and rejett the phlogiftic. In the Philofophical Tranfa&ions for 1787, however, we find a number of experiments related by Sir Benjamin Thompfon, which feem to render this matter dubious.— One very confi- derable objection is, that the green matter, already men¬ tioned in Dr Prieflley’s experiments, when carefully obferved by a good microfcope, appears not to be of a 40 vegetable, but of an animal nature. The colouring Green mat- matter of the water, fays he, is evidently of an animal ter obfer- nature ; being nothing more than the affemblage of an ^ j’V •Dr ! infinite number of very fmall, a&ive, oval-formed ani-tobeof malcules, without any thing refembling tremella, or an animal that kind of green matter or water-mofs which forms nature, upon the bottom and fides of the vefiel when this water is fuffered to remain on it for a confiderable time, and into which Dr Ingenhoufz fuppofes the animalcules above mentioned to be aftually transformed. This gentleman has alfo found, that feveral animal fubftances, as well as vegetables, have a power of fepa- rating dephlogifticated air from water when expofed to the light of the fun, and that for a very great length of time. Not.riiat the fame quantity of water will al¬ ways continue to furniih air; but the fame animal fub¬ ftance being taken out, wafhed, and again put into frefh water, feems to yield dephlogifticated air, with¬ out any kind of limitation. 41 Raw filk pofleffes a remarkable power of this kind. Dephlo- To determine it, Sir Benjamin introduced 30 grains this fubftance, previoufly walked in water, into a thin c^l by raw glafs globe 4! inches in diameter, having a cylindrical filk. neck Iths of an inch wide, and twelve inches long, in¬ verting the globe into ajar filled with the fame kind of water, and expofing it to the aftion of the fun in the window. It had not been ten minutes in this fitua- tion, when the filk became covered with an infinite number of air-bubbles, gradually increafing in fize, till, at the end of two hours, the filk was buoyed up, by their means, to the top of the water. By degrees they began to feparate themfelves, and form a collection of air in the upper part of the globe ; which, when exa¬ mined by the teft of nitrous air, appeared to be very pure. In three days he had collected 34- cubic inches of air; into which a wax-taper being introduced, that had juft before been blown out, the wick only remain¬ ing red, it inftantly took fire, and burned with a bright and enlarged flame. The water in the globe appeared to have loft fomething of its' tranfparency, and had changed its colour to a very faint greenifh caft, having 1 at Sea. III. A E R O 'Dephlogif- at the fame time acquired the fmell of raw filk.—This iticated Air. was fever.q times repeated with freih water, retaining v the fame filk, and always with a fimilar refult; but with this difference, that when the fun fhone very bright, the quantity of air produced was not only greater, but its quality fuperior to that yielded when the fan’s rays were feeble, or when they were frequent¬ ly intercepted by flying clouds. “ The air, however, (fays he), was always not only much better than com¬ mon air, but even than that produced by the frefh leaves of plants expofed in water to the fun’s rays in the ex¬ periments of Dr Ingenhoufz ; and, under the moft fa¬ vourable circumflances, it was fo good, that one mea- fure of it required four of nitrous air to faturate it, and the whole five meafures were reduced to 1.35.” 'ducecTiothe -^-n experiment was next made in order to determine dark. the effeft of darknefs upon the production of air: and in this cafe only a few inconfiderable bubbles were formed, which remained attached to the filk ; nor was the cafe altered by removing the globe into a German ftove. Some fingle bubbles, indeed, had detached themfelves from the filk and afcended to the top, but the air was in too little quantity to be meafured or proved.—The medium heat of the globe, when expo- fed to the fun’s rays, was about 90° of Fahrenheit, though fometimes it would rife as high as 96 ; but air was frequently produced, when the heat did not exceed 43 65 and 70°.—On reverfing this experiment, in order Effe&s of to try the effeCt of light without heat, it was found, light with- by plunging the globe into a mixture of ice and t out ea ■ water, which brought it to the temperature of about 50° of Fahrenheit, the produce of air was diminilhed, 44 though it ftill continued in confiderable quantity. Of artificial The effedt of artificial light, inftead of that of the hght* fun, was next tried. For this purpofe all the air was removed from the globe; and its place being fupplied with a quantity of frefh water, fo as to render it quite full, it was again inverted in the jar, and removed into a dark room furrounded with fix lamps and refleftors ; fix wax candles were alfo placed at different diftances from three to fix inches from it, and dffpofed in fuch a man¬ ner as to throw the greateft quantity of light poffible upon the filk, taking care at the fame time that the water ftiould npt acquire a greater heat than 90°. In this fituation the filk began to be covered with air- bubbles in about ten minutes; and in fix hours as much was collected as could be proved by nitrous air, when it was found to be very pure. A frefh-gathered, healthy leaf of a peach tree, and' a item of the pea- plant with three leaves upon it, furniftied air by expo- fure to the fame light, but in fmaller quantities than by the action of the folar rays. The air produced in the dark, in whatever manner procured, was always in too fmall quantity to be meafured. In making thefe experiments, as it was found fome- what troublefome to invert the globes in water, they were at laft only kept in an inclined pofture on the table, as re- prefented in PlateVIII. fig. 1. the air collecting i-tfelf in the upper part of the belly. Having provided him- felf with a number of globes of different lizes, he then proceeded in his experiments in the following manner. Various Finding that raw filk, expofed to the aCtion of light, ^ufiflancesf produced fo great a quantity of air, he was induced to for raw {ilk tr^ w*let;fier fome other fubftances might not be found ’ out capable of doing the fame. Having therefore Voi*. I. Part I. LOGY. 153 provided fix globes of qi inches in diameter, and filled Dephlogif- them with fpring water, he introduced into.each of them Seated Air. 15 grains of one of the following fubffances, viz. fheep’s v wool, eider-down, fur of a Ruffian hare, cotton wool, lint or the ravelings of linen yarn, and human hair.— The refults of thefe experiments were, 1. The globe containing the flieep’s wool began to yield air in three days ; but feveral days of cloudy weather intervening; he did not remove it for fome time, when only i^ths of an inch of air was colleCted, which proved very pure when tried with nitrous air ; but the wool, even in the moft favourable circumftances, never afforded more than one third of the quantity which would have been yielded by filk. 2. The water with the eider¬ down began to furnifli air almoft immediately, and con¬ tinued to do fo in quantities little lefs than had been furniftied by the filk, and nearly of the fame quality. One cubic inch and three quarters of this air, furniftied the eighth day from the beginning of the experiment, with three meafures of nitrous air, was reduced to 1.34. 3. The fur of the hare produced more air than the wool, but lefs than the eider-down. Two cubic inches of air were collected in four days; which made its appearance in a different manner from that of the other fubftances, the air-bubbles being at confiderable diftances from one another, and growing to an uncom¬ mon fize before they detached themfelves from the fur. The cotton yielded a confiderable quantity of air of a better quality than any of the former. The ravelings of linen were very flow in furniftiing air, and produced but a fmall quantity ; only two cubic inches being col¬ lected in the fpace of a fortnight. This fubftance ap¬ peared to be the very reverfe of the hare’s fur; for the air, inftead of attaching and collecting itfelf about the fubftance in large bubbles, fcarce ever made its appear¬ ance in fufficient quantity to raife it to the top of the water. The human hair furniftied ftill lefs than the linen, and the produce was of inferior quality, though ftill fuperior to the common atmofphere. In order to difeover the comparative finenefs of air produced from vegetables and from raw filk, a fmall quantity of air from the ftem of a pea-plant, which had four, healthy leaves upon it, was proved with nitrous air, and found greatly inferior to that from raw filk and feveral of the fubftances already mentioned. An entire plant of houfewort, of a moderate fize, furniftied only ^ths of a cubic inch of air in feven hours, and that greatly inferior to common air; but the leaves a- lone afforded a much greater quantity, and of a qua¬ lity greatly fuperior. 45 Having proceeded thus far, it was next determined the to afeertain how much air a given quantity of Water ftuantlty 0*j would yield by expofure to the fun’s rays. For this^y ^gans6 purpofe, a globe of fine white, clear, and very thin ofthefe fub- glafs, containing 296 inches, being filled with frefh fiances from fpring water, and 30 grains of raw filk immerfed in it,water* was expofed to the air for three days in the month of May, but for the moft part cold and cloudy. During this time only gi inches <5f air were produced; but next day, by expofure to the fun from nine in the morning till five in the afternoon, the weather being very fine, 8.46 inches more were produced. The wa¬ ter had now affumed a light greenifti colour. Next day, the produCt of air was nine cubic inches, of a better quality; and the day following, fix inches ftill U fuperior, ?54 AERO Dephloanf- fuperior, though expofed only for three hours and an ticated Air.half. but t}ie next day, it being cold and cloudy, only ' :'r 'si-ths of an inch of air were produced, and thefe ma- nifeftly inferior to the foregoing. No more air could afterwards be procured, excepting one quarter of a cu¬ bic inch ; fo that from 296 inches of this water, 33.96 of air were obtained. In this experiment the air produced was every day removed from the globe, and its place fupplied with water: the following were made, to determine what alteration would take place on allowing the quantity of air produced to remain from firlt to laft. The globe being therefore filled again, and the filk well waihed and replaced in it, the quantity of air produced a- mounted in four days to 30.1 cubic inchesj and would probably have been more confiderable, had not the globe been unable to contain it along with yhe water, and therefore there was a neceffity for putting an end to the experiment. The quality was fuperior to the former.—In this experiment the water had loft its tranfparency, and acquired a greeniih caft ; a quantity ef yellowilh earth was precipitated to the bottom, and attached itfelf fo ftrongly to the glafs, that it could Sot be removed without great difficulty. On varying the experiment, by employing unwaffied raw filk, it was found, that 17 grains of it in 20 cubic inches of water, produced, for the firft four days, air of a worfe quality than the atmofphere ; but afterwards yielded near two inches of a fuperior quality. The quantity of this air was fuperior to that in other expe¬ riments, though its quality was fomewhat inferior. In refle&ing on the experiments above related, it oc¬ curred to Sir Benjamin, that the cotton-like fubftance produced by the populus nigra, a fpecies of poplar tree, might be a proper fubftitute for the raw filk; efpeci- ally as he recolle&ed, that on rendering it very, dry for fome other purpofe, fome parcels of it had quitted the plate on which they were laid, and mounted up to the top of the room. An hundred and twenty grains of this fubftance were therefore put into the large globe containing 296 inches •, but after expofure to the fun for fome hours, the air produced, in quantity a- bout i|ths of a cubic inch, was found to be little bet¬ ter than phlogifticated air. In three days after, only one cubic inch was formed ; and this appeared to be completely phlogifticated. Next day, only a few in- confiderable air-bubbles appeared; but, the day fol¬ lowing, the water fuddenly changed to a greeniffi co¬ lour, and began all at once to give good air, and in great abundance. This day 10.42 cubic inches were produced, and the next I4-34- The fame water con¬ tinued to furniih air for four days longer; the whole quantity amounting to 44^ cubic inches, the quality of which was fuperior to that of the air produced in ^ former experiments. Of the canfe. In fpeculating on the caufe of this produftion of air, of this pro Jt occurred to our author, that perhaps the quantity of d.u&ion it might be in proportion to the furfaces of both. In order to afcertain this, he viewed an hair of filk, and another of poplar-cotton, through a good microfcope, when the former appeared twice the diameter of the latter. The fpecific gravity of the cotton was found logy. Sea. nr. to be nearly equivalent to that of water; and, by a Dephlogff- comparative view of the two through a microfcope, Geared Am the furfaces appeared to be as tooo to 3468. By pro- v ceeding in this calculation, it appeared that the furface of 30 grains of the cotton could not be lefs than 6600 fquare inches, while that of a like quantity of the filk amounted to no more than 476. Hence it evidently appeared, that the produce of air from the two fub- ftances was neither in proportion to their weights nor their furfaces. It appeared alfo, that the quality of the air produced at firft was confiderably inferior to that yielded fome time afterwards. In order to afcertain the times at which air of the beft quality was produ- ^ ced, &c. the following experiments were made: 1. A At what globe, containing 46 cubic inches, being filled with wa- times air of ter, and 30 grains of raw filk, well waffied, and freedtlie ' from the remains of former experiments, put into k,^uajty ** yielded in a cold and cloudy day only ^th of a cubic inch P ^ of air: the two following days it yielded 3-'-cubic inches, the quality of which was fuperior to that of the former in the proportion of ^96 to 114 (a). 2. The globe being filled again with water, in two other days when the funffiine was lefs powerful, the quality was 197, and the quantity l|th; but afterwards, when the weather became fine, the quantity was again 3.8 in¬ ches, and quality 342. 3. The globe being again fil¬ led with water, and expofed to the- fun. for two days,, yielded 2.2 inches of air, of a quality equal to 233. 4. A fimilar globe, with poplar-cotton which had been ufed in former experiments, gave 2.53 inches, of a qua¬ lity 280. 5;. A fmall globe of 20 inches, with 17 grains of raw filk, gave one cubic inch of air, of the quality 263. 6. A large globe of 296 inches, filled with frelh water, and a fmall quantity of conferva rivu-- laris, gave 1 j! cubic inch, of the quality only of 124. The water was changed to a brown colour. 7. On. repeating the experiment with a fmall handful of the conferva, 13.14 cubic inches of air were produced, of the quality 246. The water was very faintly tinged, towards the end of the experiment, of a greeniffi caft. 8. The globe of 46 inches, with 30 grains of raw filk ufed in many former experiments, produced in two days 1.6 cubic inches of air, of the quality 204, 9. A gdobe of equal capacity, with 15 grains of poplar-cot¬ ton, produced in the fame time 1.28 inches, of the quality 260. In both thefe experiments, the water had acquired a faint greeniffi caft ; but the colour of that with the cotton was deepeft. On examining this wa¬ ter with a microfcope, it was found to contain a great number of animalcules exceedingly fmall, and nearly of an oval figure ; that with the filk contained them likewife, but not in fuch numbers: however, our author affures us, that in all cafes in which the water acquired a greeniffi hue, he never failed to find them; and thinks, that from their prefence alone, the colour of the water in the firft inftjance univertally ai-ofe. 4p As Sir Benjamin was now more than ever embarrafled Experiment with refpeft to the ffiare the filk and other bodies em- *EUIi ployed in thefe experiments had in producing the air,s s' he made the following experiment to determine the matter: “ Concluding (fays he), that if filk and other bodies.

AERO Dephlogif- bodies, ufed in the foregoing experiments, actually did ticated Air. not contribute any thing, confidered as chemical fub- y ftances, in the procefs of the production of pure air yielded by water ; but if, on the contrary, they a fled merely as a mechanical aid in its feparation from the water, by affording a convenient furface for the air to attach itfelf to ; in this cafe, any other body having a large furface, and attracting air in water, might be made ufe of inftead of the fdk in the experiment, and pure air would be furnifhed, though the body Ihould be totally incapable of "communicating any thing what¬ ever to the water.” With a view to afcertain this, the large globe being made perfectly clean, and filled with fpring-water, he introduced into it a quantity of the fine thread of glafs commonly called fpun-glafs, fuch as is ufed for making a brufh for cleaning jewels, and an artificial feather fold by Jew pedlars. The refult of the experiment was, that the globe being expofed in the fun, air- bubbles began almoft inftantly to make their appear¬ ance on the furface, and in four hours 0.77 of a cu¬ bic inch of air was procured, which, with nitrous air, Ihowed a quality of 88 ; after which, not a fingle glo¬ bule more was produced, though the globe was expo- fed for a whole week in fine funlhine weather. Hence it appears, that fomething more than mere furface was wanted to produce dephlogilticated air from water by ' means of the fun’s light. Of tjje The following experiments were made with a view quantity to determine the quantity and quality of air produced and quality by means of the heat and light of the fun from water ducedPfromal.on.e' A larffe jar of clear gIafs> containing 455 cu- wateralone.bic inches, being walhed very clean, was filled with frefh fpring water, inverted in a glafs bafon of the fame, and expofed to the weather for 28 days. At the fame time, another fimilar jar was filled with water taken from a pond in a garden in which many aquatic plants were growing, and expofed in the fame place, and during the fame period. The latter began to yield air in pretty large quantities on the third day, and continued to do fo till the 14th; the former yielded little or none till the 14th, when it began to emit air, and continued to do fo till the 22d. On removing the air produced, that from the fpring-water was 14 in¬ ches in quantity, and 138 in quality; but from the pond water, 314 in quantity, and 252 in quality. The colour of the waters was not changed; but both of them had depofited a confiderable quantity of earth, which was found adhering to the furfaces of the glafs bafons in which the jars were inverted. As thefe ba- fons, however, were very thick, and confequentiy had but little tranfparency, the fediment of the water wag in a great meafure deprived of the benefit of the fun’s light; the experiment was therefore repeated with the following variations In a large cylindrical jar of very fine tranfparent glafs, to inches in diameter and 1 2 inches high, filled with fpring-water, a conical jar, 94 inches in diameter- at the bottom, and containing 344 .inches, was inverted, and the. whole expofed to the fun for 21 days. Little air was furnilhed till the 7th day, when the liquor affumed a greenifh caff, and a fine llimy fediment of the fame colour, the green matter of Dr Prieftley, beginning to be formed on the bottom, air was generated in abundance, and was furnilhed in pretty large quantities till the 18th, when it entirely LOGY. 155 ceafed. The whole amounted to 40 cubic inches, and Dtphlogif- the quality 213. treated Air. Thefe are the principal experiments contained in Sir ' " jV Benjamin Thompfon’s letter to Sir Jofcph. Banks. Dr tnsjen- In his poftfeript he obferves, that as he neVer was Houfz’s thoroughly fatisfied with the opinion of Dr Ingenhoufz, tho0r/ con" that the dephlogifticated air was elaborated in the vef- te e ’ fels of the plant, he found his doubts rather confirmed than diminifhed by the experiments above related. “ That the frelh leaves of certain vegetables (fays he), expofed in water to the a£tion of the fun’s rays, caufe a certain quantity of pure air to be produced, is a fact which has been put beyond all doubt: but it does not appear to me by any means fo clearly proved, that this air is ‘ elaborated in the plant by the powers of vege¬ tation,—phlogifticated or fixed air being received by the plant as food, and the dephlogifticated air rejected as an excrement;’ for befides that many other fub- ftances, and in which no elaboration or circulation can poffibly be fuppofed to take place, caufe the water in which they are expofed to the action of the light to yield dephlogifticated air as well as plants, and even in much greater quantities, and of a more eminent qua¬ lity ; the circumftances of the leaves of a vegetable, which, accuftomed to grow in air, are feparated from its ftem and confined in water, are fo unnatural, that I cannot conceive that they can perform the fame func¬ tions in fuch different fituations. “ Among many fadts which have been brought in fupport of the received opinion of the elaboration of air in the veffels of plants, there is one upon which great ftrefs is laid, which, I think, requires further ex¬ amination. The frefti healthy leaves of vegetables, feparated from the plant, and expofed in water to the action of the fun’s rays, appear, by all the experiments which have hitherto been made, to furnifti air only for a fhort time. After a day or two, the leaves, chan¬ ging colour, ceafe to yield air. This has been con¬ ceived to arife from the powers of vegetation being de- ftroyed, or, in other words, the death of the plant: and from hence it has been inferred, with fome degree of plaufibility, not only that the leaves actually retained their vegetative powers for fome time after they were feparated from their ftock; but that it was in confe- quence of the exertion of thofe powers, that the air yielded in the experiment was produced. “ But I have found, that though the leaves, exP0_ leaves of fed in water to the aftion of light, actually do ceafe plants re- to furnifti air after a certain time, yet that they regain fume their this power after a ftrort interval, when they furnifti (or proPerty rather caufe the water to furnifti) more and better air"after than at firft ; which can hardly be accounted for upon feeniin<>- ro the fuppofition that the air is elaborated in the veffels have loll it, of the plant.” In confirmation of this doctrine, the globe of 46 inches was filled with frelh fpring-water, and two peach- leaves were expofed for to days to the fun. In four days the water feemed to be entirely exhaufted; but, jnext day, the water acquired a greenilh cplour, and again produced air pretty plentifully, which appeared in bubbles on the leaves; and on the 6th day, 0.34 of a cubic inch of air was produced, of the quality 232. Next day it yielded -i%ths of a cubic inch, of the quality 297. The threefucceeding days it yielded ij inches, the quality 307 ; after which an end was put to the expe- U 2 riment. —- 156 AERO Dephlogif- jlment.—On making other trials with leaves immerfed ticatcd Atr. water already green and prepared to yield dephlogi- '' ftieated air, it was found that they produced air in great quantity : but our author is of opinion, that all the appearances may be folved, by fuppofing that the air was produced in the mafs of water by the green matter; and: that the leaves, filk, &c. did no more than aflilt it in making its efcape, by affording a conveni¬ ent furface to which it could attach itfelf, in order to colleft together and affume its elaftic form. Thus we fee, that nature is provided with abundant refources for the fupplying of this pure part of the at- mofphere which is fubje£t to fach continual wafte; and there is not the leaft doubt, that in a great number of cafes the light of the fun produces pure air from wa- 53 ter as well as from vegetables^ It is probable, alfo,. Pure air that even the waters of the . ocean contribute towards water mfea* t^s fehitary purpofe; as Dr Dobfon of Liverpool found, that fea-vvater contained air fuperior in quality to that of the atmofphere. The purification of atmo- fpherical air by agitating it. in water, will be confidered in a fubfequent fetStiom. 54 As dephlogifticated air is found to fupport animal JJbw to life, for a much longer time than common air, it has procure been fuppofed that it might anfwer valuable purpofes Farge^uan-10 medicine,, provided any cheap method of procuring t'ty, it ih large quantities could'be fallen upon. With this view, Mr Cavallo propofes to diftil it from nitre with a ftrong heat ; but the experiments already related cer¬ tainly point out an eafier method, free from the ex¬ pence and trouble which muft neceffarily attend every chemicar operation of this kind. $ 2. Properties of Dephlogijiicated -dir.—This kind of air pofTefies fome of the properties of common air in a very eminent degree, but is deficient in others. Thofe in which it excels* are the fupport of flame and of ani¬ mal life. It is equally elaftic, or rather more fo, than common air; as it likewife exceeds it a little in fpeeific gravity, the proportion betwixt it and common air being that of 160 to 152. On introducing a lighted candle into dephlogifticated air, the flame not only Bephlogif- grows larger, but becomes exceedingly bright; and ticated air when the air is very pure,, the candle burns with a produces in-cradling noife, as if the air contained fome combufti- cen e leat. matter, at the fame time that the wax or tallow waftes furprifingly faft. The heat of the flame is in proportion to its light. If we fill a bladder with dephlogifticated air, and then faften to its neck a glafs tube whofe aperture is drawn to a fine point, the dephlogifticated air, if driven out by prefling the bladder, will augment the heat of a candle to fuch a degree, that if any fmall bits of metal, placed on a piece of charcoal, be held in the apex of the flame, they will almoft inftantly be melted. Even grains of platina may by this means be melted ; and in a larger fire there is no doubt that the effedls of burn- ing mirrors might be equalled. Explodes On mixing dephlogifticated and inflammable air to- violently gether, an explofion takes place as on mixing com- with in- mon and inflammable air, but with much greater vio- ^aaima e jence_ jf announce vial, which for this purpofe ftiould be very ftrong, be filled with a little more than one- third of dephlogifticated and the reft inflammable air, and the flame of a candle prefented to its mouth, it will explode nearly as loud as a fmallpiftol. LOGY. Sea. XIL All phlogiftic procefles. are promoted much better Dephlogif- by dephlogifticated than; common air. Dr Prieftley ^lcateri Air; put a quantity of pyrophemis into one of the fmall jars ufed for making experiments upon air in quickfilver; 57 then filling up the veflel with that fluid, he inverted i®hemently" in a bafon of the fame, and threw in dephlogifticfited w;th pyr0.. air at different times. It always occafioned a hidden phorus. and vehement accenfion, like the flalhing of gun-pow¬ der, and the air was greatly diminiflied. It has been, ahnoft throughout all ages, believed. Common that combuftion in every inftance diminilhed common ay ‘f "ot air, or reduced it to a fmaller volume : but the late™' 7' experiments of Mr Lavoifier have fhown, that this is a miftake ; and that in ordinary procefles attended with the production of fixed and phlogifticated air, the quantity of vapour produced is equivalent to that abforbed, or otherwife made to difappear during the operation. With dephlogifticated air the cafe is very different. Mr Lavoifier having introduced a burning But depiilo- candle into a glafs jar filled with very pure air obtain- gifticated ed from calcined mercury, a great heat took place; aj.r which at firft expelled a fmall quanity of the air ; but “minutlon> afterwards, when the candle was extinguiftied, it was found that two-thirds of the bulk of air employed had been converted into fixed air, or a quantity of this kind of air equivalent to the former had been produ¬ ced. The remainder, after taking up the fixed air by cauftic alkali, was H ill as pure as before. In the com¬ mon proceffes, he obferves, that not more than one- tenth of the air employed is converted into fixed air. In this experiment, the fuperior gravity of fixed air, and the confequent £ondenfation of the other, muft undoubtedly have produced fome diminution in the volume of air, though Mr Lavoifier does not take no¬ tice of it. In other cafes, however, the diminution is much more perceptible. Mr Scheele having intro¬ duced fome live coals into a matrafs filled with dephlo¬ gifticated air, found that it was diminiihed by one- fourth of its quantity. Repeating the experiment- with fulphur, the flame became larger and more vivid, than in common air, and three-fourths of its quantity were loft. Putting a piece of phofphorus into feven ounce-meafures of this kind of air, flopping the mouth of the bottle with a cork, and fetting fire to the phof¬ phorus within it, the vial broke in pieces, as foon as the flame was extinguiflied; by the preffure of the ex¬ ternal air. Repeating the experiment with a ftronger vial, and opening it afterwards under water, the fluid rufhed into it in fuch a manner as almoft to fill it en¬ tirely. This extraordinary diminution was alfo per¬ ceived on fetting fire to inflammable air in- the dephlo¬ gifticated kind. The way in which he accompliihed this was, by filling a matrafs with dephiogifticated air, and inverting it over a phial containing an effervefcing mixture of vitriolic acid and iron-filings plunged into a veflel of hot water, and furniftied wkh a flender tube reaching above the furface of the veflel,, as reprefented Plate VIII. fig. 2. The inflammable air iffuing from- the orifice of the fmall tube, was feton fire previous , to the inverfion of the matrafs, and the mouth of the latter immerfed in the water; on which that fluid foon began to rife, and continued to do fo till feven-eighths of the veffel were full. In cafes of flow combuftion, where common air is diminilhed and phlogifticated, the dephlogifticated kind was found to be almoft en¬ tirely- Sea. III. AERO DephlogiT- tireljs deftroyed.

Very great differences are perceived in this refpetl; and according to the quan¬ tity of diminution, the air is faid to be twoj three, or four times better than common air. It is not yet accurately determined how far this proportionable pu¬ rity extends. Dr Prieftley mentions fome extrafted from red lead five times as pure as common air. Another quantity, produced from a folution of mercury in nitrous acid, was fo pure, that one meafure of it mixed with two of nitrous air, which had been obtained in the iirft part of tie fame procefs, occupied only 0.03 of a meafure. “ Repeating .the experiment (fays he), I found, that two meafures of nitrous air were rather more than fuffieient to faturate one meafure of the de¬ phlogifticated air; fo that poffibly, had the former ex¬ periment been made with more circumfpeclion, the di¬ minution, extraordinary as it was, would have been fomewhat greater. Indeed it cannot be fuppofed, that exadtly two meafures of nitrous air ftiould be the precife quantity that would afford the greateft diminu¬ tion. It fhould alfo be confidered, that a fmall por¬ tion of air might be yielded by the water in which the experiments were made. Upon the whole, therefore, I am inclined to think, that, were it poffible to make both the dephlogifticated and nitrous air in the greateft purity, and'then to mix them in fome exadt pro¬ portion, the aerial form of them both would be de- ftroyed, the whole quantity feeming to difappear, as in the mixture of alkaline and;acid-air.” Mow de- Notwithstanding this great degree of purity, the phlogifti- belt dephlogifticated air is capable of being contami- cated air nated by fome of the proceffes which affedt the com- tanunatedn,m°n a‘r our atmofpherc. Dr Piieftley having in¬ troduced a quantity of very ■dry, clean nails, into a re¬ ceiver filled with dephlogifticated air, and inverted it in quickfilver, .found,, that about nine months after, one-tenth -of the whole quantity had 3ifappeared, tho’ he could not perceive any ruft upon the nails. The effects of combuftion have already been related, viz. as producing a great quantity of pure fixed air ‘r but pu- trefaftion and animal refpiration probably contaminate it in a manner fimilar to that of atmofpherical air, though few or no experiments feem to have been made on this fubjedt. Mr Cavallo, however, informs us, that “ when an animal is confined in a quantity of de¬ phlogifticated air, and is .kept therein till it dies, that air is not rendered- fo bad but that it will ftill be ca¬ pable of confiderable diminution by nitrous air. This feems to ftiow, that dephlogifticated air is fomewhat different from pure common air ; or that common air is originally different from dephlogifticated air, lowered by the addition of phlogifton. The phenomenon is certainly very remarkable; and fometimes a quantity of dephlogifticated air, after having been breathed by an animal till it died, will appear by the nitrous teft to be even better than common air. When the expe- 2. LOGY. 157 riment is performed over lime-water (to abforb tba Dephlogif- fixed air produced in refpiration), the diminution by a ticated.Air. mixture of nitrous air is lefs than it would otherwife v " be ; but it is ftill diminiftied much more than common air after an animal has died in it; which feems to in¬ timate, that the death of the animal in dephlogiftica¬ ted air is principally owing to the fixed air formed by the act of refpiration. It may be faid, that the in¬ flammable principle difcharged through the lungs of an animal, being perhaps combined with fome other principle, requires a longer time to combine with the dephlogifticated air than the phlogifton of nitrous air; but this- is only an hypothetical explanation of the abovementioned remarkable phenomenon, which re*- quires many diredt proofs.” . Dephlogifticated air is much inferior to that of the Vegetation common atmofphere in fupporting vegetable life. This ill fupport- has been afcertained by the experiments of Dr Prieft-de- ley, Mr Fontana, Mr Scheele, Dr Ingenhoufz, &c. ^edair Dr Prieftley took three fprigs of mint, and having put all the roots.into vials containing the fame pump-water which had been for fome time expofed to the atmofphere, introduced one of them into a jar of dephlogifticated air, another into a jar of common air, and a third into that which had been phlogifticated with nitrous air fe- veral months before, and in fuch a ftate, that one meafure of it, and one of nitrous air, occupied the fpace of 1 ^ meafures. Tlris.was done in April; and , on examining them on the 12th of May following, it was found, that the plant in phlogifticated air had grown remarbably, much better than that in common air; while the plant in dephlogifticated air had a very fickly appearance.. Examining them on the 26th of the fame month, the appearance continued nearly as before; but it was now found, that though the plant in phlo¬ gifticated air had grown fo well, the air was not fen- fibly improved by it, though the dephlogifticated air was injured by the plant which grew in it. $3. Of the-Compofition of Dephlcgifticated Air.— When Dr Prieftley firft difeovered the exiftence of this Dr Prieft- fluid, having found that it was always procured by *c) ,s means of earthy fubftances; and that as it came over, -P01 !e“*’ the bubbles appeared full of fine white powder; he concluded, that it is compofed of the nitrous acid and earth, with as much phlogifton as is neceffary to its elafticity; and that the common atmofphere has as much more as is neceffary to bring it into the mean condition in which we find it. It was not long, how¬ ever, before this theory met with oppofition. Dr Prieftley himfelf, though induced, from the wafte of the folid matter ufed in his experiments, to conclude that the, air contained fome quantity of earth, was neverthelefs unable, by any method he could think of, to afeertain that quantity. His experiments were op- ^ pofed by others made by Lavoifier; who infifted, that Difference when folution of mercury was carefully diftilled, the betwixt Dr metal was obtained in full quantity, or with fcarce ?Pej'e5r\ any lofs, notwithftanding the dephlogifticated air pro- ple(. duced. This gentleman having put two. ounces and one drachm of mercury into red precipitate, and afters wards revived it, loft a very few grains of the metal; which, he fays, might be the weight of a little red matter that was found adhering to the neck of the veffel. The fame thing was obferved by Mr Fontana, who repeated the experiment often with left than a gram 158 AERO De| hlogif- grain weight o£ lofs. The veffel he ufed had a neck tieatcd A;r. 0f about two feet long : and he particularly remarks, _v that, in order to fucceed in this experiment, the fire fhould be managed with very great dexterity; for if that be too ftrong, part of the precipitate will be vo¬ latilized, and then the refult of the experiment is pre¬ carious. Thefe experiments were oppofed by others made by Dr Prieftley, who in feveral trials'found that a confi- derable quantity of the metal was always loft. In one of thefe experiments, out of 11 pennyweights 10 grains of mercury, the lofs amounted to one penny¬ weight two grains. In another experiment, 88 grains were loft, out of a quantity of red precipitate, in the preparation of which half an ounce of mercury had been employed. The quantity of mercury loft in his experiments, or rather the proportion of it to that of , the metal employed, was always various, and the dxf- Earth can- ference not very fmall; whence Mr Cavallo and others, not be pro- with great appearance of reafon, conclude, that the yt d to exifl true reafon of any perceptible lofs was the ftrong heat d' ma^e ufe °* t^e diftillation, and confequently that a;r- there is no reafon to fuppofe that any earth exifts in dephlogifticated air. The next queftion was, Whether any of the nitrous acid exifted in dephlogifticated air ? That it contains none in a proper ftate of acidity, is indeed evident from many decifive experiments ; but an idea was naturally entertained, that in the formation of dephlogifticated 66 air the nitrous acid was decompofed, and part of it en- Whether tered into the compofition of the aerial fluid. This ai-fd'enters £ave r^c to t^ie t^eories °f Mr Lavoifier and Mr its con-troll-Kirwan, which are noticed under the article Acid ; tion. as alfo the experiments of Mr Watt, which tend¬ ed to fhow that no nitrous acid was deftroyed in the compofition of dephlogifticated air. To thefe Mr Kirwan replied in the manner related in that ar¬ ticle. We fliall here, however, give a quotation from Dr Prieftley as a kind of addition to Mr Watt’s tefti- mony on this head, fo that the reader may be the bet¬ ter able to determine the weight of the evidence on both fides. “ At Mr Watt’s requeft (fays he), I endeavoured to afcertain the quantity of acid that was expelled from nitre, in procuring the dephlogifticated air from it. To do this, I put two ounces of purified nitre into a glafs retort, and receiving the air in 300 ounce mea- fures of water, only filled each recipient half full, and agitated the air very much in the water, in order to make the fluid imbibe as much as poffible of the acid it contained. Notwithftanding this agitation, however, every veffel of the air retained a ftrong fmell of the acid. The moment the air ceafed to come, I filled a large phial with the water, and carried it to Mr Watt, who carefully examined it; and in a paper which he prefent- ed to the Royal Society, and which is publilhed in the Philofophical Tran factions, he has given an account of the quantity of acid that was contained in all the 300 ounces of water: whence it may be fairly inferred, that there was no occafion to fuppofe that any of the ; tonclufions inflammable air is in too fmall proportion : and, fecond- )■ from thefe ly, by fuppofing that there is no nitrous acid mixed •r meKts* with or entering into the comppfition of dephlogifti- ; * cated air ; but that, when the air is in fufficient propor¬ tion, part of the dephlogifticated air with which it is debafed is, by the itrcng affinity of phlogifton to de- s phlogifticated air, deprived of its phlogifton, and turn¬ ed into nitrous acid; whereas, when the dephlogifti¬ cated air, is not more than fufficient to confume the in¬ flammable air, none then remains to deprive the phlo¬ gifticated air of its phlogifton, and turn it into acid.— If the latter explanation be true, I think we muft al¬ low that dephlogifticated air is in reality nothing but dephlogijlicated water, or water deprived of its phlo¬ gifton ; or, in other words, that water confifts of de¬ phlogifticated air united to phlogifton. On the other hand, if the former explanation be true, we muft fup- pofe, that dephlogifticated air confifts of water united to a little nitrous acid, and deprived of its phlogifton ; but ftill the nitrous acid in it muft only make a very fmall part of the whole, as it is found that the phlo¬ gifticated air into which it is converted is very fmall in comparifon of the dephlogifticated air. I think the fecond of thefe explanations feems much the more like¬ ly ; as it was found that the acid in the condenfed li¬ quor was of the nitrous kind, not only when the de¬ phlogifticated air was prepared from nitrous acid, but when procured from plants or turbith mineral. Ano¬ ther ftrong argument in favour of this opinion is, that dephlogifticated air yields no nitrous acid when phlo¬ gifticated by liver of fulphur ; for if this air contains nitrous acid, and yields it when phlogifticated by ex- plofion with inflammable air, it is very extraordinary that it (hould not do fo by other means. But what forms a ftronger, and, I think, almoft decifive argu¬ ment in favour of this explanation, is, that when the dephlogifticated air is very pure, the condenfed liquor is made much more ftrongly acid by mixing the air to be exploded with a little phlogifticated air.” The experiments of Dr Prieftley alluded to were . thofe in which inflammable air was fuppofed by Mr Lavoifier to be procured from water by palling its fteam through red-hot ft on tubes. It was foon difco- vered, however, by Dr Prieftley, that this inflammable air did not proceed from the water, but from the iron of the tube; and mightbe obtained by tranfmitting aqueous vapour through charcoal or iron placed in tubes of cop¬ per, glafs, or earthen ware, made red-hot, but not through thefe tubes by the-mfelveSb In this cafe, the lofs of the water employed exceeded that of the inflam¬ mable air produced in the proportion of 1.3 to 2; and the iron which had thus abforbed the v/ater, appeared exa&ly fimilar to that which had been burned in de¬ phlogifticated air in the 'manner already related. His 81 . conclufions from thence are thefe : “ Since iron gains His opinion r)le fa.rae addition of weight by being melted in de- the'eompo- phlogiftmated air, and alfo by the addition of water fition of Von. I. Part I. 80 Dr Prieft¬ ley’sexperi- LOGY. 161 when red hot, and becomes, as I have already obfer- DepMogft- ved, the fame fubftance in all refpefts, it is evident that Uc‘ltc‘ this air or water, as exifting in the iron, is the very fame thing; and this can hardly be explained but on the fuppofition that water confifts of two kinds of air, viz. inflammable and dephlogifticated.” Of thefe procefles he gives the following explana¬ tion : “ When iron is heated in dephlogifticated air, we may fuppofe, that, though part of its phlogifton efcapes, to enter into the compofition of the fmall quantity of fixed air which is then procured, yet enough remains to form water with the dephlogifticated air which it has imbibed, fo that this calx confifts of the intimate union of the pure earth of iron and of water; and therefore, when the fame calx, thus faturated with wa¬ ter, is expofed to heat in inflammable air, this air en¬ ters into it, deftroys the attra&ion between the water and the earth, and revives the iron, while the water is expelled in its proper form.” The whole of the Dottor’s opinions on the compo¬ nent parts of this kind of air, however, are fummed up o^ferv an3 in the following fentence in his Obfervations relating to Exper. vi. Theory,.—“ The only kind of air that is now thought 402. to be properly elementary, and to confift of a Ample fubftance, is dephlogifticated air ; with the addition at leaft of the principle of heat, concerning which we know very little 5 aftd as it is not probable that this adds any thing to the weight of bodies, it can hardly be called, an element in their compofition. Dephlogifticated air appears to be one of the elements of water, of fixed air, of all the acid's, and many other fubftances, which, till lately, have been thought to be fimple.” The experiments of the French philofophers were of Sis, the fame nature with thofe of Mr Cavendifh, but con- dufted on a larger feale. The inference drawn from ^ pren;;L them was the fame with that already mentioned, viz. philofo- that dephlogifticated and inflammable air in all cafes phers. are the two conftituent parts of water. This opinion is adopted by Mr Kirwan in his Treatife on Phlogijlon. “ The experiments of Mr Cavendilh, and of Mr Mr Kir- Monge,” fays he, “ appear to me to leave no room to "’^’5 coa* doubt, that when very pure dephlogifticated and in- flammable air are inflamed, the product is mere wa¬ ter (a) ; for when thefe airs are employed in the pro¬ per proportion, only 0.02 of the mixture of both airs retains its aerial form. Now it is impoffible to fuppofe that all the water obtained pre-exifted in thefe airs ; that is, that 49 parts in 50 were mere water. Notwithftanding thefe pofitive conclufions, however, 84 by fome of the moft refpeftable names in this country, Theforego- the. evidences adduced have been unfatisfaefory to fome altoge-* French chemifts ; who maintain, that Meffrs Caven- ,her fatfs_ difh, Prieftley, and Kirwan, are totally miftaken with fa- perature of the room where the experiment was made, the diminution did not appear to exceed one-fixtieth part.—This air which had been refpired by the fpar*-, row, though in many refpe&s fimilar to that in which the mercury had been calcined, differed from it in this refpeft, that it precipitated lime-water, and, by intro¬ ducing cauftic fixed alkali to it, was redficed one-fixth in bulk by the abforption of fixed air; after which it appeared exactly the fame with that produced by the calcination of mercury or other metals; and atmofphe- rical air was recompofed by mixing this with pure de- phlogifticated air in the proportions already men¬ tioned. 93 That common air is'compounded of two kinds of Scheete’s elaftic fluids, Mr Scheele has proved by the following expert- experiment“ I diffolved (fays he) one ounce of al- snents. haline liver of fulphur in eight ounces of water; of this folution I poured four ounces into an empty bottle, whofe capacity was 24 ounces, and worked it well; then I turned the bottle, immerfed its neck into a fmall veffel with water, and kept it in this pofition a fort¬ night. The folution had partly loft its red colour, and feme fulphur had been precipitated from it during this time. After this I put the bottle in the fame pofition in., a larger veffel with water, keeping the mouth and neck under water, and the bottom of the bottle above water, and thus I drew the cork under water, which immediately ruflied with violence into the bottle. On examining the quantity of water in the bottle, it was found, that during this fortnight, fix parts out of 20 of air were loft.” On repeating the experiment with the fame materials, and in the fame bottle, only four parts out of 20 were loft by ftanding a'week, and no more than fix after four months. , From thefe experiments, and many, others fimilar, Compofi- & appears that the doftrine of phlogifton had been car- tion of at- ried too far by Dr Prieftlqy and other Britifh philofo- mofphericalphers, and that the air confifts of two kinds of fluids; ftrated10"" one Perfe<^iy fahttary, and friendly in the higheft de¬ gree to animal life; the other altogether unfit for it. Thefe two appear incapable of being converted direft- ly into one another by any procefs, natural or artifi¬ cial: for though both are deftruttible, yet they are il>vays cpnverted into other fubftancss;-from which, indeed, either the one or the other may be extracted PhlogifH- at pleafure by employing the proper methods. The fated Air“, ftrongeft arguments in favour of the tranfmutation of , phlogifticated air into that of a purer kind, were drawu from the purification of noxious air by vegetation, and by agitation in water. In the former cafe, however, , it has been obferved in the laft flection, that this feem- ing purification is no other than an exchange of the one air for the other; the vegetables abforbing the ■ phlogifticated, and' emitting the dephlogifticated air in ; its ftead. With refpeft to the agitation in water,- the. • matter remained more dubious; and it-is ,only in theh«wair is laft volume of Dr Prieftley’s treatife that-we have any purified by account of this being accompliftied by an emiflion of aSItation iri purer air from the water. ■—U- Iri the infancy of my ex- gXper amj; periments,” fays he, “ I conduded, that all kinds of obferv. vi* air were brought by agitation to the fame ftate ; the 385 pureft air being partially-phlogifticated, and air com¬ pletely phlogifticated being thereby made purer ; in¬ flammable air alfo lofing its inflammability^ and all of them brought into fueh a ftate as that a cancfle would juft go out in them. This inference I made from all the kinds of air with which I was then acquainted, and which did not require to be confined by mercury, being brought to that ftate by agitation in a trough of wa¬ ter, the furface of which was expofed to the open air ; never imagining that when the air in my jar was fepa¬ rated from the common air by a body of water, gene¬ rally about twelve inches in depth (adding that with¬ in to that without the jar), they could have any influ¬ ence on each other. I have, however; been long con¬ vinced, that, improbable as it then-appeared to me, this is a&ually the cafe.”’ This remarkable fact is illuftrated by the following 98 experiments : 1. About three ounce-meafures of air, Water per- phlogifticated by nitrous air, was agitated for a quar- viousto air,. frr • /ri c ar>d purifies- ter or an hour in a veilel containing 20 ounces of wra-;t ;n pa{pint,. ter, which had been boiled for feveral hours, and which through, was ftill very warm. By this procefs it became dimi- nifhed one-fixth, and confiderably improved in qua¬ lity. The next day the remainder was agitated for another quarter of an hour, and the- water which had been boiled at the fame time, when it was alfo diininifhed in quantity and improved in quality. 2. An equal quantity of air, phlogifticated by means of iron-filings and brimftone, being agitated for 20 minutes, was diminiftied by one-feventh, and improved fo far that a candle would burn in it. 3. After ex¬ pelling all the air he could from a quantity of water by boiling, he put to it, in feparate phials, air that had been phlbgifticated with iron-filings and brimftone, as well as that which the heat had expelled, leaving them with their mouths in water, and agitating them occafionally. Oh examining the phials in-about two. months, he found both the air that was confined by water and that which had been expelled by heat com¬ pletely phlogifticated. 4. That water does imbibe the purer part of the atmofphere, in preferehce to that which is impure, is evident, he fays, from any examination of it: For if the water be clear, and free from any thing that is putrefeent, the air expelled from it by heat is ge¬ nerally of the ftandard of 1; whereas that of the atmo¬ fphere, when the nitrous air is the pureft, is about 1.2. Phlogifticated air is equally invifible with common 99. air, and fomething more efaltic. ^Mr Kirwan pro-ofphlogiftl-. cured catedjur. |! Ni Sea. IV. AERO i PMogifti- cured fome perfectly phlogifticated, fo that it was not ' in the leail diminiihed by nitrous air, from a mixture of iron-filings and brimftone. Having dried it by frequently introducing dry filtering paper under the jar that contained it, he found its weight to be to that of the common air as 985 to 1000, the barometer Hand¬ ing at 30.46 and the thermometer at 6o°. The other properties of it are, that it is extremely fatal to ani¬ mal life, and friendly to that of vegetables, infomuch that it is now generally believed to be the true and proper nourifhment of the latter. It feems to exift originally, in very large quantity, in our atmofphere. It may be feparated from the common mafs of air by combuftion, by refpiration, by putrefaction, afid in Ihort by every fpecies of phlogiftic procefs.; neither is there any other fpecies of air but what may be converted into this by means of fire, dephlogifficated air alone excepted. Phlogifticated air is now generally believed to be a combination of the nitrous acid with phlogifton; and U that, in its gradual progrefs towards this, which is its I phlogiftka- ultimate ftage, it firft a flumes the character of phlo- ted air. gitlicated nitrous acid 5 then of nitrous air, in which it readily parts with its phlogifton to the atmofphere, or rather to the dephlogifticated part of ft; and laftly, it I becomes phlogifticated air, in which the union betwixt the principles is fo ftrong, that it cannot be broken by • Ample expofure to dephlogifticated air without heat; though the experiments- of Mr Cavendifh fhow, that this may be done by mearre of the ekcfric fpark, which produces the moft violent heat'we can imagine. It had been frequently obferved, that common at- mbfpherical air was always diminiffied by taking the electric fpark in it; and this dminution was fuppofed to be occafioned by the phldgtfticaiion of the air, and fepa- ration of its fixed part; in confequenee of which it was urged,.‘that lime-water is precipitated by taking the eleftric fpark over-it in a fmall quantity of air. toi Mr Cavendifh, however, who has carefully examined Mr Caven- this fubjeft, denies that any fixed air is produced in i s e!£Pl?" this manner; and by a fet of very curious experiments, the*prlduc-Puh^cd in the 75th volume of the Philofophical tionofni- Tranfaftions, has clearly fhown that nitrous acid, and trous acid, not fixed air, is the produft of this operation. The apparatus ufed in thefe experiments, was that reprefented Plate Vril. fig. 4. and confifts only of a crooked glafs tube, whofe ends are phmged into quick- filver contained in two glafies, in the middle part of which the air is confined betwixt the two portions of quickfilver. The air was introduced by means of a fmaller tube, fig. 5. the' tube M of the former fi¬ gure being filled with quickfilver, the bent end of which, was introduced into a jar DEF, filled with the pro¬ per kind of air, and inverted in water. The end ■ 0 • being Hopped by the finger, the quickfilver was thus prevented from falling out, let the tube be placed in what pofition* it would, until this preffure was removed. Upon introducing the crooked tube into the jar in the pofition reprefented in the figure, and removing the finger from the orifice at C,. the quickfilver would de- fcend ; and by flopping this orifice again, any quan¬ tity of the fluid may be allowed to run out, and the empty fpace of the tube will be filled with the air de- fitred. Having thus got the proper quantity of air in¬ to the tube ABC, it was held with the end C upper- rnoft, and. flopped with the finger ; and the end A, o Y. 165 made fmaller for that purpofe, being introduced Into Phlogifti- the end of the bent tube M, the air, on removing the ^ated Alf-, finger from C, was forced into that tube by the pref- v fare of the quickfilver in the leg BC. Thus he was enabled to introduce any quantity he pleafed of any kind of air into the tube M; and by the fame means it was in his power to let up any quantity of foap-ley, or other liquor which he wanted to be in contadl with it. In one cafe, however, in which he wiftied to introduce air into the tube many times in the fame experiment,. he made ufe of the apparatus reprefented fig. 6. Con¬ fining of a tube AB, of a fmaller bore, .a ball C and a tube DE of a larger bore. This apparatus was firft filled with quickfilver; and then the ball C and the tube AB were filled with air, by introducing the end A under a glafs inverted into water, which contained- the proper kind of air, and drawing out the quick¬ filver from the leg ED by a fyphon. rAfter beigg thus furnifhed with air, the apparatus was weighed, and the end A introduced into one end of the tube M, and kept there during the experiment; the way of forcing air out of this apparatus into the tube being by thruft- ing down the tube ED, a wooden cylinder of fuch a fixe as almofl to fill up the whole bore, and by occa- fionally pouring quickfilver into the fame tube, to fup- ply the place of that puftied into the ball C. After the experiment was finifhed, the apparatus was weigh¬ ed again, which ftiowed exaflly how much air had been - forced into the tube M during the whole experiment; it being equal in bulk to a quantity of quickfilver, whofe weight was equal to the increafe of weight of the apparatus. The bore of the tube M, ufed in thefe experiments, was about the tenth of an inch in dia¬ meter ; and the length of the column of air occupying the upper part of the tube was in general from -j-ths tt> 1 { inches.-—In order to force an ele&rical fpark through the tube M, it was necefiary to place an in- fuMed ball at.fuch a diftance from the conduflor as to receive a fpark from it, and to make a communication - between that ball and the quickfilver in one of the glafles, w-hile the quickfilver in the other glafs commu¬ nicated with the ground. When the electric fpark was made to pafs through- • common air included between ftiort Columns of a folu- tion of litmus, the folution acquired a red colour, and - the air was diminifhed, as had been obferved by Dr Prieftley. When lime-water was ufed inftead of the foliition of litmus, and the fpark was continued till the air could be no farther dlininiftied but not the fmalleft - cloud be perceived in the water, though the air was- reduced to two thirds of its original bulk ; which is a greater diminution than it could have fuffered by any phlogiftic procefs, that being little more than one-fifth of the whole.: The experiment being repeated with impure dephlogifticated air, a great diminution took place, but without "any cloud in the lime-water. Nei¬ ther was any cloud produced when fixed air was let up into it ; but, on the addition of a little cauftic volatile alkali, a brown fediment immediately appeared. ( It being thus evident that the lime was faturated by fome acid produced in the operation, the experiment was repeated with foap-leys, to difcover the nature of it. A previous experiment had been made in order to know what degree of purity the air ought to be of tu produce the greateft diminution; and thus it was found, 166 AERO Phlogiili- Found, that when good dephlogifticated air was ufed, cated Air. ^ tp,e diminution was but fmali; where perfedtly yihlo- ' gifticated air was made ufe of, no fenfible diminution Proportions took place ; but when five parts of pure dephlogiftica- of the dif- ted air were mixed with three of common air, almoft ferent airs t}le w}10]e vvas made to difappear.—It muft be remcm- for the pro- hered, that common air confifts of one part of dephlo- dudtion of gifticated and four of phlogifticated air ; fo that a uitiousacid. mixture of five parts of pure dephlogifticated air and three of common air, is the fame thing as a mixture of feven parts of dephlogifticated air with three of phlogifticated. Having made thefe previous trials, he introduced into the tube a little foap-leys, and then let up fome dephlogifticated and common air mixed in the above mentioned proportions, which, rifing into the tube M, divided the foap-leys into its two legs. As faft as the air was diminiftied by the eledtric fpark, he continued to add more of the fame kind till no further diminution took place. The foap-leys being then poured out of the tube, and feparated from the quick- filver, feemed to be perfectly neutralized, as they did not at all difcolour paper tinged with blue flowers. On evaporating the liquid to drynefs, a flnall quantity of fait was left, which was evidently nitre, from the manner in which a paper impregnated with the folution ■of it burned. On repeating the experiment on a lar¬ ger fcale, with five times the quantity of materials, pure nitre was obtained in proportion, and was found, by the tell of terra ponderofa falita, to contain no more vitriolic acid than what might have been expedted in the foap-ley itfelf, and which is exceedingly fmall. As, in fome former experiments of Mr Cavendilh, -difli’s (wi-* ^ keen found, that by deflagrating nitre writh nionson the charcoal, the whole of the acid was converted into nature of phlogifticated air, he concluded that this kind of air j>hlo;pftica- is nothing elfe than nitrous acid united to phlogifton ; tea air. according to which, it ought to be converted into ni¬ trous acid by being deprived of its phlogifton. “ But (fays he) as dephlogifticated air is only water depri¬ ved of phlogifton, it is plain, that adding dephlogifti- cated air to a body, is equivalent to depriving it of phlogiftcn, and adding water to it; and therefore phlogifticated air ought alfo to be reduced to nitrous acid, by being made to unite or form a chemical com¬ bination with dephlogifticated air; only the acid thus formed will be more dilute than if the phlogifticated air was fimply deprived of phlogifton. “ This being premifed, we may fafely conclude, that in the prefent experiments, the phlogifticated air was ■enabled, by means of the eleftrical fpark, to unite to, -or form a chemical combination with, the dephlogifti¬ cated air, and was thereby reduced to nitrous acid, which united to the foap-leys, and formed a folution of nitre; for in thefe experiments the two airs actually -difappeared, and nitrous acid was formed in their room ; and as it has been fhown, from other cireumftanccs, -that phlogifticated air mull form nitrous acid when combined with dephlogifticated air, the abovemention- ed opinion feems to be fufficiently eitabliftied. And a further confirmation is, that no diminution of air is per¬ ceived when the eledtric fpark is pafled either through pure dephlogifticated or through perfectly phlogifti¬ cated air; which indicates a necelfity for the combi¬ nation of the two in order to produce nitrous acid. It was alfo found by the laft experiment, that the. 3 LOGY. Sea. IV. quantity of nitre produced was the fame that would Phlogiftj- have been obtained from the foap-leys, had they been ca‘ei^ faturated with nitrous acid; which fhows, that the y production of the nitre was not owing to any decom- pofitioa of the foap-leys. “ The foap-leys ufed in the foregoing experiments were made from fait of tartar prepared without nitre, and were of fuch a ftrength as to yield one-tenth of their weight of nitre when faturated with nitrous acid. The dephlogifticated air was alfo produced without nitre ; that ufed in the firft experiment with the foap-leys being procured from the black powder formed by the agitation of quickfilver mixed with lead, and that ufed in the latter from turbith mineral. In the firft experiment, the quantity of foap-leys ufed was 35 meafures, each of which was equal in bulk to one grain of quickfilver ; and that of the air abforbed was 416 fuch meafures of phlogifticated air and 914 of dephlogifticated. In the fecond experiment, 178 meafures of foap-leys were ufed; which abforbed 1920 of phlogifticated air and 4860 of .dephlogifticated. It mull be be obferved, however, that in both experi¬ ments fome air remained in the tube undecompofed, whofe degree of purity I had no means of trying ; fo that the proportion of each fpecies of air abforbed cannot be known with much exadlnefs. “ As far as the experiments hitherto publilhed extend, we fcarcely know more of the nature of the phlogifti¬ cated part of the atmofphere, than that it is not dimi- nilhed by lime-water, cauftic alkalis, or nitrous air; that it is unfit to fupport fire or maintain life in ani¬ mals ; and that its fpecific gravity is not much lefs than that of common air: fo that though the nitrous acid, by being united to phlogifton, is converted into air polfefled of thefe properties ; and, confequently, .though it was reafonable to fuppofe, that part at leall of the phlogifticated air of the dtmofphere confifts of this acid united to phlogillon ; yet it might be fairly doubted whether the whole is of this kind, or whe¬ ther there are not, in reality, many different fubltan- ces confounded by us under the name Y)f phlogifticated I0^ air. I therefore made an experiment to determine Experi- whether the whole of a given portion of the atmo- ment to de fphere could be reduced to nitrous acid, or whether there te™>i e was not a part of a different nature from the reft, which "hlogiftie* would refufe to undergo that change. For this pur- ted air. pofe, I diminifhed a fimilar mixture of dephlogiftica¬ ted and common air in the fame manner as before, until it was reduced to a fmall part of its original bulk ; after which fome dephlogifticated air was add¬ ed, and the fpark continued until no further diminu¬ tion took place. Having by thefe means condenfed as much as I could of the phlogifticated air, I let up fome folution of liver of fulphur to abforb the dephlo¬ gifticated air ; after which only a fmall bubble of air- remained unabforbed, which certainly was not more than -r l oth of the bulk of the phlogifticated air let up into the tube ; fo that if there is any part of the phlogifticated air of our atmofphere which differs from the reft, and cannot be reduced to nitrous acid, we may fafely conclude, that it is not more than Trjth part of the whole.” Though thefe experiments had fhown, that- the chief caufe of this diminution of airs is the converfion of the phlogifticated kind into'nitrous acid, it feemed not ' Sea. V. AERO S Phlogiftj- not unlikely, that when any liquor containing inflam- 1 ^atf d Air‘, mable matter was in contaft with the air in the tube, fome of this matter might be burnt by the fpark, and T05 thereby diminilh the air. In order to determine this, i! Effects of the eleftric fpark was palled through dephlogifticated I tjie cledric air included between different liquors; and the refult dephlogifti-t^ie experiments was, that when dephlogifticated 3 catedairin-air, containing onb’ ^oth part of its bulk of phlogi- I cMed be- fticated air, was confined between Ihort columns of I tween diffe- foap-leys, and the fpark palled through it till no far- ’ rent 11uors' ther diminution could be perceived, the air loft ^^-ds of its bulk; which is not a greater diminution than might very likely proceed from the decompofition of the fmall quantity of phlogifticated air contained in it, as the dephlogifticated air might eafily be mixed with a fmall quantity of common air while putting into the tube. When the fame dephlogifticated air was con¬ fined between columns of diftilled water, the diminu¬ tion was rather greater than before, and a white pow¬ der was formed on the furface of the quickfilver be¬ neath : the reafon of which, in all probability, was, that the acid produced in the operation corroded the quickfilver, and formed the powder; and that the ni¬ trous air produced by that corrofion united to the de¬ phlogifticated air, and caufed a greater diminution than would otherwife have taken place. When a fo- lution of litmus was ufed inftead of diftilled water, the folution foon acquired a red colour ; fwhich grew paler and pale? as the fpark was continued, till it became quite colourlefs and tranfparent. The air was dimi- mfhed'by almoft one-half, and might perhaps have been further diminilhed had the fpark been continued. When lime-water was let up into the tube, a cloud was formed, and the air was further diminilhed by about one-fifth ; the remainder was good dephlogifti¬ cated air. ■ In this experiment, therefore, the litmus was, if not burnt, at leaft decompounded, fo as to lofe entirely its purple colour, and to yield fixed air; fo that, though foap-leys cannot be decompounded by this procefs, yet the folution of litmus can, and fo very likely might the folutipns of many other fub- ftanees be. But there is nothing in any of thefe ex¬ periments which favours the opinion of the air being at all diminilhed by means of phlogifton communica¬ ted to it by the electric fpark. Sect. V. Of Fixed Air. The difeovery of this kind of air is as old as Van 10£ Helmont; who gave it the name of gas ftlveftre, from Fixed air its being emitted in great quantity by burning char- found in a coal. Subfequent difeoveries Ihowed, that a fluid of r™-the fame kind was plentifully produced by fermenting fuaces! liquor, in almoft every kind of combuftion, and natu¬ rally generated in vaft quantity in mines and coal-pits, where it is known by the name of the choak-damp ; that it exifts in a concrete ftate in alkaline falts, chalk, limeftone, the Ihells of marine animals, magnefia alba, • "See. in a very large proportion, conftituting one-half, and fometimes more of their weight; and that it might always be extracted from the atmofphere, in unlimit¬ ed quantity, by expofing certain fubftances to it.— ■On examining the nature of this fluid, it was found fo manifeftly acid, that it has now obtained a place among thefe fubftances under the name of aerial acid; LOGY. i67 or, more improperly, cretaceous acid, from its being Fixed Air. contained in great quantities in chalk, as has been al- "v ' ready mentioned. Fixed air is the heavieft of all permanently elaftic g I°7 fluids, excepting thofe derived from the mineral acids, gravity Mr. Kirwan determines it to be to common air as 1500 of fixed air! to 1000, the barometer being at 29.85, the thermo¬ meter at 64, and the fixed air being extracted from calcareous fpar by marine acid, whofe fpecific gravity was 1.0x45. He obferves, however, that though this air was obtained in the drieft manner poffible, and that, the globe which contained it appeared perfe&ly free from moifture; yet, when carried into a room 27 de¬ grees colder, the infide of the globe was covered with dew, which foon formed vifible drops.—In its concrete ftate, fixed air is one of the heavieft bodies in nature. Mr Kirwan, in the 71 ft volume of the Philofophical TranfaCtions, gives an account-of his ingenious method of finding the fpecific gravity of fixed air in its fixed ftate, when combined with calcareous earth; from which it appears, that fixed air, in that ftate, is pro- digioufly concentrated, and, were it poffible to exift by itfelf in that concentrated ftate, it would be the heavieft body known, gold and platina excepted. Mr Kirwan firft afeertained the fpecific gravity of a piece of white marble; then expelled the fixed air irom a known weight of it finely powdered, by means of di¬ luted vitriolic acid; the bulk and weight of the obtain¬ ed fixed air being afeertained. Next, 'he calcined a known quantity of the fame fort of marble, by keeping it in a white heat for the fpace of J4 hours; after which, being weighed again, and from the weight loft by this calcination, the weight of the fixed air, which muft have efcaped from it according to the above men¬ tioned experiment, being fubtra&ed, the remainder is. the weight of water contained in the marble; from, which experiments it appears, that 100 grains of the marble contained 32.42 grains of fixed air, 11.66 grains- of water, and 55.92 grains of pure calcareous earth. “ I next (fays he) proceeded to difeover the fpecific gravity of the lime. Into a brafs box, which weighed 607.65 grains, and in the bottom of which a fmall hole was drilled, I fluffed as much as poffible of the finely- powdered lime, and then ferewed the cover on, an ft weighed it both in air and in water. When immerfed in this latter,, a confiderable quantity of common air was expelled; when this ceafed, I weighed it. The refult of this-experiment is as follows: Grains.. 607.65- 73-75 1043-5 43^-85 256.5 182.3 Weight of the box in air Its lofs, of weight in water, Weight of the box and lime in air Weight, of the lime fingly in air Lofs of weight of the box and lime in water Lofs of weight of the lime fingly - - “ Hence, dividing the abfolute weight of the lime by its lofs in water, its fpecific gravity was found to be 2.3908 “ From thefe data I deduced the fpecific gravity of fixed air in its fixed ftate ; for 100 grains of marble con- fift of 55.92' of earth, 32.42. of fixed air, and 11.66 of water ; and the fpecific gravity of the marble is 2.717. Now the fpecific gravity of the fixed air, in its fixed ftate, is as its abfolute weight, divided by its lofs of weight in water; and its lofs of weight in water is a s the. *6* AERO tfixed Air, the lofs of *00 grains of marble, minus the lofles of the v 1 pure calcareous earth and the water. • Lofs of xoo grs. of marble =-i£!5L.—grs.

Its acidity is manifeft to properties. tjle tafte, and ft ill more from its neutralifing both fixed and volatile alkalis ; which it will do in fuch a manner as not only to deflroy their caufticity, but to give them a manifeflly acid tafte, and will moreover enable them to form cryftals of a neutral or acidulous fait. It has a confiderable antifeptic power, and will even check the putrefaftion of animal fubftances; though it has been obferved, that in this cafe it a&s only by abforbing the putrid effluvia already emitted from the body, and be- ■comes itfelf very offenfive, while it fweetens the other. When taken into the lungs, it is equally poifonous with phlogifticated or any other noxious air, and extinguifhes flame as effectually; but, when mixed with dephlogif- ticated air, may be infpired without any danger, and even in its pure ftate may be fwallowed in large quan¬ tities, not only without danger, but with the moft fa- lutary effeits in fome difeafes, whence it has now be¬ come an article of the Materia Medica. As an acid it Hands in the loweft rank, being expelled from alkalis by every other; though it is capable of feparating oils, fulphur, and the colouring matter of Pruffian blue, from the fubftances with which they are combined. 109 The origin of this acid was for a long time as muck Conftituent unknown as that of the others; and while the general of fixed air Preiuc^ce remained that acids were a kind of primary ’ elements unchangeable in their nature, it was fuppofed that fixed air was fome modification of the others, pro¬ bably the nitrous. - But the difcoveries made of late years, have abundantly fhown, that the chemical prin¬ ciples are 'by no means fo indeftrudtible as they were imagined; and that the vegetable acids particularly, may be almcft totally refolved into fixed air. Hence it was naturally fuggefted, that fixed air itfelf might be.a compound of fome other principles ; and it was fuggefted by Dr Black, that it was a combination of atmofpherical air with phlogifton. As the air of our atmofphere, however, is compounded of two fubftances, one of which naturally contains no phlogifton, and the other as much as it can hold; it feemed unlikely that there Ihould be any poffibility of adding to the quantity of phlogifton contained in a portion of the atmofphere, without decompofing it in fome manner or other. Suc¬ ceeding experiments evinced, that it was by a decom- pofition of the pure part of atmofpherical air, and a combination of the phlogifton of the fuel with its bafis, that fixed air was produced; and this faft was evinced by numerous experiments made by Mr Kirwan, Mr Lavoifier, and Dr Prieftley, fo that it is now looked upon to be generally eftablilhed: and as the experiments N° 5- ■ Se&.V. made by Dr Prieftley appear fully as convincing as Fixed Air. any, we fhall here content ourfelves with giving an ac- 1 v— count of them. The compound nature of fixed air, and the principles no from which it is formed, were firft difcovered by Mr Dr Priefi- Kirwan; but Dr Prieftley was not convinced by the 1 proofs he adduced, till after making fome experiments the compo- !| of his own. The firft was, by firing (havings of iron fition of 1 in dephlogifticated air; when he obferved a confider- flxed air» : able refiduum of fixed air, though that in the receiver had be?n of the pureft dephlogifticated kind, and iron could only have yielded inflammable air. The hypo- thefis of Mr Kirwan was (till further confirmed by an experiment in which iron-filings, which could only have yielded inflammable air, were mixed with red precipi¬ tate, which is known to yield only pure dephlogifti¬ cated air. On heating thefe in a glafs retort, they gave a great quantity of fixed air, in fome portions of which nineteen-twentieths were abforbed by lime-wa¬ ter, and the refiduum was inflammable ; but when the red precipitate was mixed with powdered charcoal, which had been found to yield only inflammable air, the fixed air produced from. it was fo pure that only one-fortieth part remained unabforbed by water, which is as pure as that generally prepared from chalk and oil of vitriol. In fome of thefe experiments it appeared, that three ounce-njeafures of dephlogifticated air went teethe compofition of two of fixed air : for one ounce of red precipitate gave 60 ounce-meafures of dephlo¬ gifticated air; and, when mixed with two ounces of iron-filings, it gave about 40 ounce-meafures of fixed air that were actually abforbed by water, befides a re¬ fiduum that was inflammable. The fame proportion was obtained when half the quantity of materials were made ufe of; but on ufing an onnee of each, only 20 ©unce-meafures of fixed air, including the refiduum, could be got. In confidering this fubjeeft farther, it occurred to Dr Prieftley, that his experiments, in which charcoal was ufed, lay open to an objection, that fince dry wood, and imperfectly made charcoal, yield fixed air, it might be faid, that all the elements of fixed air are contained in charcoal; and though this fubftance alone, even with the affiftance of water, will not yield fixed air, this might be effedted by treating it with other fubftances without, their importing any thing to it; efpecially as the inflammable air procured from charcoal by means of water, appears to contain fixed air when decompofed with the dephlogifticated kind. In order to expel all the fixed air from charcoal, hfe made a quantity of it from dry oak, and pounding it while hot, inftantly mixed four meafures of it with one of red precipitate, and, putting them into an earthen retort, got, with a heat no greater than what was fufficient to revive the mercury, a large quantity of air, half of which was fixed. Afterwards the proportion of fixed air was lefs, and at laft no fixed air at all was obtained; but as the refiduum was worfe than the common atmofphere, he is thence inclined to believe, notwithftanding Mr Caven- pofed of phlogifton and dephlogifticated air. In ano- concernin ther experiment he found a better proportion of char- the comp coal and red precipitate. This was by mixing one fition of ounce of precipitate with the fame quantity of perfect i char- e air’ || -Sf %• Sea, V. AERO Fixed Air. charcoal hot from the retort in which it was made. 11,1 *' Putting thefe into a coated retort, he expelled from them, by a ftrong heat, about 30 ounce-meafures of air, the whole of which was the pureft fixed air, leaving only about one-fortieth part unabforbed by water, and this almofl: perfectly phlogifticated. Having recolle&ed, that in fome former experiments .he had obtained fixed air from nitrous acid and char¬ coal, he therefore repeated the experiment with fome of the fame charcoal which had then been made ufe of; when fixed air was obtained, in the quantity fometimes only of one-fifth, and fometimes of one-half; to the for¬ mation of which he fuppofed the dephlogifticated air produced by heating the nitrous acid mutt have contri¬ buted. On account of the obje&ions, however, which might he made to the ufe of charcoal, he next employ- ed ;V(3A , which was liable to nothing of this kind; and on mixing an ounce of iron-filings with as. much char¬ coal, and then heating them in a glafs retort, he ob¬ tained 20 ounce-meafures of air, of which one-feventh remained unabforbed by water. The refiduum was of the ftandard of i.yz, but flightly inflammable. Re¬ peating the experiment with half an ounce of iron filings, he got 26 ounce-meafures of air, of which the firft part was pretty pure, but afterwards one-tenth remain¬ ed unabforbed by water ; but on mixing one ounce of precipitate with two ounces of filings, he got about 40 ounce-meafures of air, of the firft portions of which only one-twentieth was unabforbed by water, though towards the conclufion the refiduum was greater. In this procefs he got in all 36 ounce-meafures of pure fixed air, completely abforbed by water, befides about other four ounce-meafures, which, he fuppofes, might have been abforbed in receiving the air and transferring it into other velfels. Fixed air was alfo produced from red precipitate mixed with brafs filings, with zinc, from turbith mi¬ neral with iron filings, and from the black powder into which mercury mixed with lead is eafily converted. In this laft cafe the Dodftor fuppofes that the fixed air was produced from the dephlogifticated kind abforbed by the metals and the phlogifton of the lead; and this is t x confirmed by an obfervation that the fixed air always # comes firft in the procefs, when the phlogifton is moft * _ readily feparated, but afterwards the produce becomes quite pure and dephlogifticated. In attempting, how¬ ever, to increafe the quantity of fixed air by heating this black powder in dephlogifticated air, he found on¬ ly an augmentation of the quantity of dephlogifticated air, and that of the pureft kind. “ Perhaps,” fays he, “ as decifive a proof as any of the real production of fixed air from phlogifton and de¬ phlogifticated air, may be drawn from the experiments in which I always found a quantity of it when I burn¬ ed fulphur in dephlogifticated air. In one of thefe ex¬ periments, to which I gave particular attention, fix ounce-meafures and an half of the dephlogifticated air were reduced to about two ounce-meafures, and one- fifth of this was fixed air. When both the vitriolic acid and fixed air produced by this operation were abforbed by water, the remainder was very pure dephlo¬ gifticated air. “ I had always concluded, that no fixed air could be procured by the decompofition of inflammable air which had been produced by mineral acids, becaufe I Vol. I. Part I. o Y. 169 had not been able to do it with that which I had got Fixed Air. by means of vitriolic acid; but I learned from Mr Me- v f therie, that this is peculiar to the vitriolic acid, the re¬ mains of which, diffufed through the inflammable air, procured by it, he conje&ures, may actually decompofe the fixed air produced in the procefs. For, as I have hinted before, when the inflammable air is produced from iron by means of fpirit of fait, there is a very per¬ ceivable quantity of fixed air when it is united with de¬ phlogifticated air. When I decompofed -thefe two kinds of air in equal quantities, they were reduced to about 0.5 of a meafure, and of this not more than a- bout one fortieth part was fixed air. This experiment ought, however, to be added to the other proofs of fixed air being produced by the union of dephlogifti¬ cated air and phlogifton. , ii “ The laft inftance, which I fnall mention, of the Preportion generation of fixed air from phlogifton and dephlogif- ticated air, is of a much more ftriking nature than any that I have yet recited. Having made what I call phlogiftica- charcoal of copper, by palling the vapour of fpirit of ted air. wine over copper when it was red-hot, I heated a piece of it in different kinds of air. In common air, obfer- ving neither increafe nor decreafe in the quantity, I concluded, perhaps too haftily, that no change was made in it : for when I repeated the experiment in dephlogifticated air, the charcoal burned very intenfe- ly ; and when a part of it was confumed, which (like common charcoal in the fame procefs, was done with¬ out leaving any fenfible refiduum) I found that no heat which I could apply afterwards, had any farther effeft on what was left of the charcoal. Concluding, there¬ fore, that fome change muft be made in the quality of the air, I examined it, and found about nine-tenths to be the pureft fixed air ; and the refiduum was fuch as would have been made by feparating the abfolutely pure part of the dephlogifticated air, leaving all the impuri¬ ties behind.—Having afcertained this fadl, I repeated the experiment, weighing the piece of charcoal very carefully before and after the procefs ; and then found, that by the lofs of one grain of charcoal, I reduced four ounce-meafures of dephlogifticated air till one-ninth on¬ ly femained unabforbed by water ; and again, with the lofs of one grain and an half of the charcoal, I reduced fix and an half-meafures of dephlogifticated air till five and an half-meafm-es were pure fixed air. In this pro¬ cefs there was a diminution of bulk after the experi¬ ment, as might have been expected from the change of the air into one of a heavier- kind by means of a fub- ftance or principle that could not add much to the weight of it. In one of the experiments, 4.3 ounce- meafures of dephlogifticated air were reduced about one-thirtieth part of the wdiole ; and in this cafe, when the fixed air was fepaxated by water, there was a refi¬ duum of 0.75 of a meafure of the ftandard of 1.0, whereas the dephlogifticated air, before the experiment, had been of the ftandard of 0.2. “ That dephlogifticated air actually enters into the compofition of the fixed air, in this experiment, is evi¬ dent from the weight of the latter, which far exceeds that of the charcoal difperfed in the procefs. For, in this laft experiment, the weight of the fixed air pro¬ duced was 4.95 grains. Confequently, fuppofing the charcoal to be wholly phlogifton, as it is very nearly fo, fixed air may be faid to confift of 3.45 parts of dephlo- Y gifticated 1 Effects of the eledfrie fpark on fixed air. Pneftley’s hypothefis concerning the compo fition of phlogiftica- AERO giftlcated air, and 1.5 of phlogifton; fo that the de- phlogifticated air is more than three times the propor¬ tion of phlogifton in it.—I muft not conclude, how¬ ever, without obferving, that, in one experiment, I ne¬ ver failed to produce fixed air; though it is not eafy to fee how one of its fuppofed elements, viz. dephlogifti- cated air, could enter into it. This is by heating iron in vitriolic acid air. In one of thefe experiments, four ounce-meafures of the vitriolic acid air were reduced to 0.65 of an ounce-meafure; and of the quantity loft three and an half meafures were fixed air abforbed by lime-water, and the remainder weakly inflammable.” Fixed air, even when pure and unmixed, is remark¬ ably altered by the eleftric fpark, part of it being thus rendered immifcible in water. Dr Prieftley,. having taken the electric fpark for about two hours in a fmall quantity of fixed air confined by mercury, found, that after the operation one-fourth of it. remained immifci¬ ble with water; though, before it, only one-thirtieth part had remained unabforbed. The infide of the tube had become very black ; which, in other experiments of a fimilar kind with vitriolic acid air, he had obferved to arife from the adhefion of a fmall quantity of mer¬ cury fuperfaturated with phlogifton. In another ex¬ periment, in which the fpark was taken an hour and ten minutes in about half an ounce-meafure of fixed air, one-fifth remained unabforbed, and the ftandard of the refiduum was 0.9; though, before the operation,only one-thirtieth part had been abforbed,: and the ftandard of the refiduum was 1.0. In this experiment, alfo, he ob¬ ferved, that the air was increafed about a twentieth part. On taking the eledtric fpark an hour in half an ounce of fixed air, as much refiduum was left as had remained in five times the quantity of the fame fixed air in which no fpark had been taken. This refiduum was alfo much purer than that of the original fixed air, the ftandard being 0.8 ; whereas that of the original fixed air had been, as before, 1.0. On repeating the experiment, he found the refiduum ftill greater, but equally pure ; and, in this cafe, a good quantity of black matter was obferved adhering to the tube. Ha¬ ving taken the fpark in a fmall tube containing i^j-th of an ounce-meafure of fixed air, the infide of the tube was clouded with black matter, and in the bottom was a fmall quantity of yellowifli matter refembling ful- phur ; the refiduum was between one-fourth and one- fifth of the whole, and lefs pure than formerly. This circumftance he alfo fuppofes to be a proof that fixed air may be compofed of phlogifton and de- phlogifticated air. Purfuing this experiment, by ta¬ king the eledtric fpark three hours in a fmall quantity of fixed air, he obferved that it was firft increafed, and then diminifhed about one-eighth of the tvhole; the infide of the tube being very black on the upper part; And below the mercury veiy yellow, for the fpace of a quarter of an inch all round the tube; but1 this fpace had been above the mercury in the beginning of the operation. One-third of the air remained unabforbed by water; but fo impure, that jthe ftandard of it was 1.8, or almoft completely phlogifticated.—Varying the procefs by ufing water impregnated with fixed air inftead of mercury, the quantity of air was; much aug¬ mented by that which came from the. water ; but thus the far greater part of it was .incapable of being ab¬ forbed by lime-water; and on this occafipn he obfer- L O G Y. Seft.V. ved, that water impregnated with fixed air is a much Fixed Air. worfe conductor of eleftricity than the fame fluid im-' v pregnated with mineral acids. On ftill varying the circumftances of the experiment, by ufing common water inftead of that which had'abforbed fixed air, he found that the quality of the refiduum was evidently better than that of the original fixed air. 115 In order to difcover whether the heat or light ofFffe&s^of a the eledtric fpark were the circumftances which effect- ^?r. ed the change, the Doctor threw a ftrong light, by means of a lens, for fome hours, on a quantity of pounded glafs confined in fome fixed air; but though the volume of refiduum was thus fomewhat increafed, •yet as it was of the fame quality with common air, he fufpefted that it might be only that portion which had been introduced among the particles of the glafs. The quantity of air was increafed after the operation. With glafs-houfe fand made very hot, the quantity of air was likewife increafed ; but the experiment was not more fatisfadtory than the former. Heated bits of crucibles increafed the quantityof refiduum in the pro¬ portion of 10 to 6.6 ; but the quality was injured ei¬ ther diredlly by a comparifon with nitrous air, or by producing a larger quantity of refiduum: equally bad. By heating iron, however, in fixed air, part of it was evidently converted into phlogifticated air. On heat¬ ing turnings of malleable iron for fome time in fixed air, one-tenth part of it was rendered immifcible with water; and on repeating the procefs with the remain¬ der, there was a refiduum of one-fourth of the whole. There was alfo a fmall addition to the quantity of air after the firft part of the procefs, but none after the fecond; nor could he, after a third and fourth pro¬ cefs, render more than one-fourth immimible with wa¬ ter. In two experiments, the refiduum was inflam¬ mable, and burned with a blue flame. 1T^ With regard to the quantity of fixed air which may Quantity of be expelled from different fubftances, Dr Prieftley ob- fixed air ex- ferves, that from feven ounces of whiting, the pureftP^J™111 calcareous fubftance we are acquainted with, he expel- fubftanc"es. led by heat 630 ounce-meafures of air; by which means the whiting was reduced to four ounces. One third of this was fomewhat phlogifticated ; the ftand¬ ard being 1.36 and 1.38. Repeating the experiment, he obtained 440 ounce-meafures of air from fix ounces of whiting ; about one-half of which was fixed air, and the remainder of the ftandard of 1.4. On moiftening fome calcined whiting with water impregnated with vi¬ triolic acid air, he obtained 90 ounce-meafures; of which the firft portions v/ere three-fourths fixed air, and the ftandard of the refiduum 1.5; the latter had lefs fixed air,: and the ftandard of the refiduum was 1.44. The whiting was rendered black and hard, but became foft and wliite .with fpi.rit of fait. Three ounces and a •quarter of lime fallen in the air, yielded 375 ounce- irieafures; of which about one-fifth was fixed air, and the ftandard of the refiduum 1.4. Four ounces of white lead had yielded 240 meafures of air when the retort melted. The refiduum tof the firft procefs was one- third, the ftandard 1.36 ; and of the laft the ftandard was iv28, that with the common atmofphere being 1.23. Two ounces and three quarters of wood-afhes yielded, in a very ftrOng heat, 430 ounce-meafures of air ; of the firft portion of which one-tenth, of the fe¬ cond one-third, and of the third one-half, was fixed Sea. VI. AERO Fixed Air. a[r. The ftandard of the refiduum of the firft portion was 1.6, and of the fecond 1.7. It extinguifhed a candle ; fo that the air came properly from the a flies, and not from any remaining particles of the charcoal mixed with them. After the procefs, the afhes weigh¬ ed 839 grains; but by expofure to the air for one day, the weight was increafed to 842 grains; and, perhaps with more heat than before, yielded 50 ounce-meafures of air; of which about one-eighth was fixed air, and the ftandard of the refiduum 1.3 8 and 1.41. A can¬ dle burned in this refiduum, and the afhes were redu¬ ced to 7894- grains. Two ounce-meafures of Hom- berg’s pyrophorus burned in the open air, and then diftilled in a retort, yielded 144 ounce-meafures of air; of which one-half at'firft was fixed air, but at the laft very little. The refiduum of the firft portion ex- tinguifhed a candle, but that of the laft burned with a blue lambent flame. The ftandards of both with ni¬ trous air were about 1.8. The pyrophorus was then kept two days in the retort, with the mouth immerfed in mercury; after which, on being taken out, it burn¬ ed as ftrong as ever. Immediately before the burning, it weighed 428 grains; immediately after it, .449 : but being fpread thin and expofed to the atmofphere for a night, the weight was increafed to 828 grains; though, on being well dried, it was again reduced to 486. Subjefting it to a greater heat than before, the matter yielded no ounce-meafures of air; the firft portions of which were half fixed air, but the laft con¬ tained very little, and burned with a blue lambent flame. It was then reduced to 396 grains. The ex¬ periment was then repeated with a quantity of pyro¬ phorus, which would not take fire in the open air; and on heating this fubftance in an earthen retort, five- fevenths of the firft part of the produce was fixed air: but this proportion gradually diminifhed; till at laft nine-tenths of the whole was inflammable air, burning with a lambent blue flame. This inflammable air be¬ ing decompofed with an equal quantity of dephlogifti- cated air, yielded 0.86 of a meafure of fixed air. A- Hother quantity of pyrophorus, which burned very \Vell, and which by expofure to the atmofphere had gained 132 grains, being again expofed to heat in an earthen retort, gave 180 ounce-meafures of air; three-fevenths of the firft portion of which was fixed, and the reft phlogifticated air; but afterwards only one-half was fixed and the reft inflammable, burning with a lambent blue flame ; and at laft it was wholly inflammable. This pyrophorus took fire again after being poured out of the retort, but not without the afliftance of ex¬ ternal heat. It had been red-hot through the whole mafs at the firft burning, and the furface was covered with white allies ; but all the infide was as black as ever it had been. Four ounces of dry ox-blood yield¬ ed 1200 ounce-meafures of air, and it was conje&ured that not lefs than 200 meafures had efcaped. It con¬ tained no fixed air. The firft portion burned with a large lambent white flame, the middle portion fainter, and the laft was hardly inflammable at all. The re¬ maining coal weighed 235 grains, and was a good con¬ ductor of eleftricity. Sect. VI. Inflammable Air. We owe the knowledge of the exiftence, andoffome remarkable properties, of this air, to Mr Cavendilh, by LOGY. 171 whom they were firft publilhed in 1767. Its effedts,b'flamma- however, had long before been fatally experienced by Air- miners ; in whofe fubterraneous habitations it is often ^r; collected in fuch quantities as to produce the moftinflamma- dreadful effedts. It is produced in abundance from hie air pro- putrid animal and vegetable fubftances; and, in gene- '*uce(l'n ral, by all thofe which part with their phlogifton ea- lily. Being much lighter than common air, it always ters, &c. rifes to the top of thofe places where it is generated ; fo that it cannot be confined except in fome vaulted place, but always ftrives to afeeud and mix with the atmofphere. By itfelf it is very noxious, and will in- ftantly put an end to animal life ; but when mixed with atmofpherical air, may be breathed in much greater quantity than fixed air. Its great inflamma¬ bility in this ftate, however, renders it very dangerous to bring any lights, or even to ftrike a flint with fteel, in thofe places where it abounds. But this only takes place when the inflammable air is mixed with common atmofpherical or with dephlogifticated air ; in which cafe, the explofion is much more violent than the for¬ mer ; for pure inflammable air extinguilhes flame as effedtually as fixed or phlogifticated air. Befides the fubterraneous places already mentioned, this kind of air is found in ditches; over the furface of putrid waters, out of which it efcapes; in burying- •places; in houfes of office, where putrid animal and vege¬ table matters are accumulated; and may, by Handing or boiling, be extra&ed from the waters of moft lakes and rivers, efpecially thofe in which great quantities of fermenting and putrefying matters are thrown : and as putrefaftion thus feems to be the principal fource of inflammable air, it thence happens, that much more Greatqiiait - of it is produced in warm than in cold climates. In tides pro- thofe countries, we are informed by Dr Franklin, that ducc,r\in if the mud at the bottom of a pond be well ftirred, and jutes' a lighted candle brought near to the furface of the wa¬ ter immediately after, a flame will inftantly fpread a confiderable way over the water, from the accenfion of the inflammable air, affording a very curious fpcftacle in the night-time. In colder climates, the generation of inflammable air is not fo plentiful as to produce this phenomenon ; neverthelefs Mr Cavallo informs us, that it may be plentifully procured in the following manner, up in all the ponds about London. “ Fill a wide-mouthed Mr Caval- bottle with the water of the pond, and keep it invert- *°’s ed therein ; then, with a ftick, ftir the mud at the ^rinflam- bottom of the pond, juft under the inverted bottle, fomable an¬ as to let the bubbles of air which come out of it enter from'ponds. into the bottle ; which air is inflammable. When by thus ftirring the mud in various places, and catching the air in the bottle until this is filled, a cork or glafs ftopper muft be put over it whilft ftanding in water; and then the bottle muft be taken home, in order to examine the contained inflammable fluid at leifure.” i20 The great quantity of inflammable air produced in Meteors warm climates has given occafion to fome philofophers thou£,l)t to to fuppofe, that it may pofiibly have fome ftiare in producing certain atmofpherical meteors. The weak lightnings without any explofion, which are fome- times perceived near the horizon in ferene weather, are by them conjectured to proceed from inflammable air fired by electric explofions in the atmofphere. Mr Volta fuppofes that the ignes faiui are occafioned by the inflammable air which proceeds from marfhy Y 2 grounds. 172 AERO Inflamma* grounds, and is fet on fire by eleftric fparks: but thefe ^ic A'ir- ! phenomena can be accounted for in a more probable " "v manner from the aftion of the eleftric fluid itfelf. This kind of air is more common than any of the other noxious airs; for there is hardly any inflammable fubftance on earth, out of which it may not be ex- trafted by one means or other. The fluids, however, which go by the generel name of inflammable air, have fcarce any other property in common to them all, be- i?,r fides thofe of inflammability, and being fpecifically Differences lighter than the common atmofpherical air. In other among in- refpefts, the differences between them are very confi- airs!maWe derable. The fmell, weight, power of burning, of preferving their properties, and the phenomena attend¬ ing their combuftion, are by no means the fame in them all; fome burning in an explofive manner; others quietly, and with a lambent flame of a white or blue colour. It is, however, neceflary to make a proper diftinftion between an inflammable elaftic fluid or inflammable gas, which may be properly called fo, and that which is evidently made by combining an in¬ flammable fubftance with common air; which being eafily feparable from the air, leaves that fluid in the ftate it was before. Thus a drop of ether, put into a quantity of common air, mixes itfelf with it, and takes fire on the approach of flame, like a mixture of inflam¬ mable and common air; but if the air to which ether js added be wafhed in water, the latter is foon fepara- ted from it. Common air becomes alfo inflammable by being tranfmitted through feveral effential oils ; and thus the air contiguous to the plant called fraxi- nella becomes inflammable in calm and hot weather, m ky the emiffion of its inflammable air. Extra&ed By heat alone, a confiderable quantity of this kind from vafi- 0f a;r may be extrafted from moft inflammable fub- ces b^heat" I^ances’ ant^ even ^rora ^ome the metals. Dr Hales e s y .ea • obtained inflammable air by limply diftilling wax, pitch, amber, coals, peafe, and oyfter fhells ; and Mr Fontana informs us, that he obtained a confiderable quantity of inflammable air from fpathofe iron, by the aftion of fire only applied to it in a matrafs. Dr Prieftley, however, obtained it from a vaft number of other fubftances, by diftilling them in a gun-barrel; to the extremity of which was luted a tobacco-pipe, or fmall glafk tube, with a flaccid bladder tied on the end. He obferves, that the heat muft be fuddenly *33 applied, in order to get a coafiderahle quantity of air More air from thefe fubftances. “ Notwithftanding (fays he) procured by ^ fatne care be taken in luting, and in every other *haUnd^u-refpeftj fix, or even ten, times more air may be got at heat. by a hidden heat than by a flow one, though the heat that is laft applied be as intenfe as that which was ap¬ plied fuddenly. A bit of dry oak, weighing about twelve grains, will generally yield a fheep’s bladder full of inflammable air with a brifk heat, when it will only yield two or three ounce-meafures if the fame heat be applied gradually.” When he wanted to ex- traft inflammable air from metals, a*glafs was ufed, the focus of which afforded a more intenfe heat than any furnace he could apply : and in this way he obtained inflammable air from feveral metals; as iron, brafs, and tin; but with the metallic calces he had no fuc- cefs. In the infancy of his experiments, and even after vtery confiderable practice, the Doftor imagined, that LOGY. Sea. VI. the inflammable air produced in this way came only Inflamma- from the metal, without attending to the fhare which Ah. water had in the produftion. Some late experiments ' ^ of Mr Lavoifier, however, Ihowed, that water had a How pro¬ great ftiare in the produftion of inflammable air ; info- cured from much that it gave occafion to a fuppofition, that thevvater an.fi water was the only fource from whence it was derived, and^ohd ^ This miftake, however, was detefted by Dr Prieftley; fubftances. who, by his numerous and accurate experiments, feems in a manner to have exhaufted the fubjeft. The me¬ thod which Mr Lavoifier had followed, was to fend the fteam of boiling water through a red-hot iron tube; in doing which, the intenfe heat acquired by the water occafioned the produftion of a great quan¬ tity of inflammable air. Dr Prieftley repeated his ex¬ periments not only with water, but with other fluids. Sending the vapour of two ounces of fpirit of wine through a red-hot earthen tube, he obtained 1900 ounce-meafures of inflammable air, which burned with a white lambent 'flame. It contained no fixed air ; and 30 ounce-meafures of it weighed eight grains lefs than an equal quantity of common air. He collefted alfo 0.35 of an ounce-meafure of water. In this experi¬ ment, the weight of the water collefted was 168 grains, of the inflammable air 633 grains, and that of the fpirit of wine originally was 821 grains; fo that as little was loft in the procefs as could be expefted.— Repeating the experiment with vitriolic ether, an ounce of it treated in the fame manner in an earthen tube almoft filled with pieces of broken earthen retorts and crucibles, one tenth part of an ounce of water was collefted, and 740 ounce-meafures of inflammable air were pro¬ cured, without any mixture or fixed air, burning with a white lambent flame like that of wood, and not exploding with dephlogifticated air. Twenty- nine ounce-meafures of this weighed five grains lefs than an equal quantity of common air. Vapour of fpirit of turpentine yielded inflammable air mixed with much black fmoke, which foon collefted on the fur- face of the water in the receiver. The fmell of this air was exceedingly offenfive, and its flame was much lefs luminous than that of the former. Its fpecifia gravity was the fame with that of the air procured from fpirit of wine. Olive oil yielded a confiderable quantity of air on being mixed with calcined whiting ; the firft portions burning with a large white flame, and the laft with a lambent blue one. In extrafting air from folid fubftances, the fteam of water was always neceflary ; and thus inflammable air was produced from a great number of different ones. From fulphur treated in this manner in an earthen tube, inflammable air was obtained of a nature fimilar to that from oil of vitriol and iron. From ar- fenic, the produce was one-feventh of fixed air; but all the reft ftrongly inflammable, with a fmell fcarcely diftinguifhable from that of phofphorus. Twenty ounce-meafures of this air weighed 44- grains lefs than an equal quantity of common air. Both thefe experi¬ ments, however, were very troublefome, on account of the volatility of the matters, which fublimed and choaked up the tubes. From two ounces of the fcales of iron, or fining cinder, which he has found to be the fame thing. Dr Prieftley obtained 580 ounce- meafures of air ; one-tenth of the firft part of which was fixed air, but afterwards it was all inflammable. Forty f Sea. VI. AERO Inflamma- Forty ounce meafures of this air weighed two grains j*16 Air more than an equal quantity of common air. From v charcoal expofed to the red-hot Iteam of water, in¬ flammable air was procured in great quantities. From ninety-four grains of perfedf charaoal, that is, prepared with a ftrong heat fo as to expel all fixed air from it, and 240 ounces of water, 840 ounce-meafures of air were obtained, one-fifth part of which was fixed air; and the inflammable part appeared likewife, by decom- pofition, to have a quantity of fixed air intimately combined with it.—Three ounces of bones burnt black, and treated in this manner in a copper tube, yielded 840 ounce-meafures of air; the water expended being 288 grains, and the bones lofing 1 io grains of their weight. This air, he obferves, differs confiderably from that of any other kind of inflammable air; being in feveral refpefts a medium betwixt the air procured from charcoal and that from iron. It contains about one-fourth of its bulk of uncombined fixed air, but not quite one-tenth intimately combined with the re¬ mainder. The water that came over was blue, and pretty firongly alkaline; owing to the volatile alkali not having been totally expelled by the heat which had reduced the bones to blacknefs. A variety of fubftances, faid not to contain any phlogifton, were fubje&ed to the fame procefs, but without yielding any inflammable air. The experi¬ ments with iron, however, were the moft fatisfaftory, as being fubjeft to lefs variation than thofe with char¬ coal ; and clearly evincing, that the air in the procefs does not come from the water alone, but from the iron alfo; or, as Dr PriefUey fays, “ only from the iron ; the weight of water expended, dedu&ing the weight of air produced, being found in the addition of weight in the iron as nearly as could be expefted in experiments of this kind. And though the inflam¬ mable air procured in this procefs is between one- third and one-half more than can be procured from iron by folution in acids, the reafon may be, that much phlogifton is retained in the folutions; and therefore much more may be expelled from iron when pure water, without any acid, takes place of it. The produce of air, and likewife the addition of weight gained by the iron, are alfo much more eaftly afcer- tained in- thefe experiments than the quantity of water expended in them; on account of the great length of the veffels ufed in the procefs, and the different quan¬ tities that may perhaps be retained in the worm of the T2J tub> Proper- The following are the refults of fome of the Doc- tiuns of in-tor’s experiments.- Two hundred and fixty-feven flammable grains, added to the weight of a quantity of iron, pro- ed from111' ^uced a lofs of 336 grains of water, and an emiflion iron by °f 840 ounce-meafures of air; and in another experi- tneans of ment, 140 grains added to the weight of the iron Seam. produced a lofs of 240 grains of water, and the emif- fion of 420 ounce-meafures of air. “ The inflammable LOGY, 173 air produced in this manner (fays he) is of the lightell kind, and free from that very offenfive fmell which is , e Air' ^ generally occafioned by the rapid folution of metals in oil of vitriol; and it is extricated in as little time in this way as it is polfible to do it by any mode of folu¬ tion. The following experiment was made with a view to afcertain the quantity of inflammable air that may be procured in this manner from any given quan¬ tity of iron. Nine hundred and fixty grains of iron, when diffolved in acids, will yield about 800 ounce- meafures of air ; but, treated in this manner, it yield¬ ed 1054 meafures, and then the iron had gained 329 grains in weight” (a). ii6 Inflammable air having been at firft produced only ®^t^e^coa 1 from metals by means of acids, it was then fuppofed prjndplcsof that part of the acid neceffarily enters into its compo- inflamma- fition; but this hypothefis is now found to be ill blc air. grounded. “ That no acid (fays Dr Prieftley), is ne- „ ^.7 ceffarily contained, or at leaft in any fenfible quantity, co°t^|;c(j either in inflammable air, though produced by means in it. of acids, or in the dephlogifticated air of the atmo- fphere, is evident from the following experiment, which'- I made with the greateft care : Taking a bafon which contained a fmall quantity of water tinged blue with the juice of turnfole, I placed it in a bent tube of glafs, which came from a veffel- containing iron and diluted oil of vitriol; and lighting the current of in¬ flammable air as it iffued from this tube, fo that it burned exactly like a candle, I placed over it an in¬ verted glafs jar, fo that the mouth of it was plunged in the liquor. Under this jar the inflammable air burn¬ ed as long as- it could ; and when extinguifhed for want of more pure air, I fuffered the liquor to rife as high as it could within the jar, that it might imbibe whatever fhould be depofited from the decompofition of either of the two kinds of air. I then took off the jar, changed the air in it, and, lighting the ftream- of inflammable air, replaced the jar as before. This I did till I had decompofed a very great quantity of the two kinds of air, without perceiving the leaft change in the colour of the liquor, which muft have been the cafe if any acid had entered as a neceffary conftituent part into either of the two kinds of air.. 1 alfo. found no acid whatever in the water, which was procured by keeping a ftream of inflammable air con- ftantly burning in a large glafs balloon, through which the air could circulate, fo that the flame did not go out. Neither was there any acid produced in the de¬ compofition of inflammable and dephlogifticated air in a ftrong clofe glafs veffel. “ With refpeft to inflammable air, I have obferved, that when fufficient care is taken to free it from any acid vapour that may be accidentally contained in it, it is not in the fmalleft degree affetted by a mixture of alkaline air. On the whole, therefore, I have at pre- fent no doubt, but that pure inflammable air, though it certainly contains •water, does not neceffarily contain any (a) In thefe experiments, the D.oftor feems not to have fuppofed that any particular kind of water was ne- celfary for this production of inflammable air: but in the Memoirs of the Philofophical Society at Haerlem, it is afferted by Dr Deiman and M.. Paets Van Trooftwyk, that the experiment will not fucceed when boiled or diftilled water, or any other than that containing fixed air, is made ufe of; and to this air they attribute the calcination of the iron and production of inflammable air- This affertion,. however, is contrary to what we find related by Mr Kirwan. Seen0 138.. 174 AERO Tnflamma- any acid: yet an acid vapour maybe eafdy difFufed ^le '‘’r' ) through it, and may perhaps in many cafes be obfti- v nately retained by it, as no kind of air feems to be ca¬ pable of fo great a variety of impregnations as inflam- 12 8 mable air is.” Water ne- Mr Cavendifli firft perceived the neceflity of moi- k^roduc ^ure t0 t^e produ&ion of inflammable air ; but it was tioii. C not 11 ntd after making feveral experiments that Dr Prieftley could adopt the fame idea. He had obferved fome very remarkable circumftances relating to the produ&ion of inflammable air from charcoal, by which he was induced to fuppofe that the former was pure J2g phlogiilon in a volatile ftate without any moifture Charcoal whatever. The Doftor obferves, that “ charcoal is totally con- generally faid to be indeftrudtible, except by a red toTnfliwn-1" heat in contact with air. But I find (fays he), that it mable air. Is perfectly deftrudtible, or decompofed, m vacuo, and, by the heat of a burning lens, almoft convertible into inflammable air; fo that nothing remains befides an exceedingly fmall quantity of white allies, which are feldom viflble, except when in very fmall particles they happen to crofs the fun-beams as they fly about the receiver. It would be impoflible to collect or weigh them ; but, according to appearance, the alhes thus i.;o produced, from many pounds of wood, could not be Weight of fuppofed to weigh a grain. The great weight of afhes veeffrorn " Pro^uce^ by burning wood in the open air arifes from the air. what is attracted by them from the air. The air which I get in this manner is wholly inflammable, without the lealt particle of fixed air in it. But in order to this, the charcoal muft be perfeftly well made, or with fuch a heat as would expel all the fixed air which the wood contains ; and it muft be (Jontinued till it yield inflammable air only, which, in an earthen retort, is foon produced. “ Wood or charcoal is even perfectly deftru&ible, that is, refolvable into inflammable air, in a good earthen retort, and a fire that would about melt iron. In thefe circumftances, after all the fixed air had come over, I feveral times continued the procefs during a whole day; in all which time inflammable air has been produced equably, and without any appearance of a termination. Nor did I wonder at this, after feeing it wholly vanifh into inflammable air in vacuo. A quantity of charcoal made from oak, and weighing about an ounce, generally gave me about five ounce- meafures of inflammable air in twelve minutes.” Experi- Although from thefe experiments it did not appear j. ent fhow- that water was in any way efientially neceflary to the cefilf16 f6" Produ&i°n this kind of inflammable air, it appeared water* to wianifeftly to be fo in the following: “ At the time the produc- (fays he) when I difperfed any quantity of charcoal with tion of in- a burning lens in vacuo, and thereby filled my receiver flammable with nothing but inflammable air, I had no fufpicion that the wet leather on which my receiver flood could have any influence in the cafe, while the piece of char¬ coal was fubjeft to the intenfe heat of the lens, and placed feveral inches above the leather. I had alfo procured inflammable air from charcoal in a glazed earthen retort for two whole days fucceffively, during which it continued to yield it without intermiflion. Alfo iron-filings in a gun-barrel, and a gun-barrel it- fclf, had always given inflammable air whenever I tried LOGY. Sea. IV. the experiment. Thefe circumftances, however, de- Infiamma- ceived me, and'perhaps would have deceived any other 7" A‘r~ perfon ; for I did not know, and could not have be- lieved, the powerful attraction between water and char- Excel live coal or iron, when the latter are intenfely hot. They attraction will find, and attract it, in the midft of the hotteft ^^coal or fire, and through any pores that may be left open in jron an(j a retort; and iron-filings are feldom fo dry as not to water, have as much moifture adhering to them as is capable of enabling them to give a coniiderable quantity of in¬ flammable air. But my attention being now fully awakened to the fubjett, I prefently found that the circumftances above mentioned had actually mifledme ; I mean with refpeft to the conclufion which I drew from the experiments, and not with reipeCt to the ex¬ periments themfelves, every one of which will, I doubt not, be found to anfwer, when properly tried. “ Being thus apprifed of the influence of unper¬ ceived moifture in the production of inflammable air, and willing to afeertain it to my perfeCt fatisfaCfion, I began with filling a gun-barrel with iron-filings in their common ftate, without taking any-particular pre¬ caution to dry them, and I found that they gave air as they had been ufed to do, and continued to do fo many hours : I even got ten ounce-meafures of inflam¬ mable air from two ounces of iron-filings in a coated glafs retort: At length, however, the production of inflammable air from the-gun-barrel ceafed ; but, on putting water to it, the air was produced again ; and ,23 a few repetitions of the experiment convinced me that Inflamma- I had been too precipitate in concluding that inflam-blt;airisnot mable air is pure phlogifton. I then repeated the ex- °~ periment with the charcoal, rnaking the receiver, theS ftand on which I placed the charcoal, and the charcoal itfelf, as dry and hot as pofiible, and ufing cement in- ftead of wet leather, in order to exclude the air. In thefe circumftances I was not able, with, the advantage of a good fun and an excellent burning lens, to decom- pofe quite fo much as two grains of the piece of char¬ coal which gave me ten ounce-meafures of inflamma¬ ble air ; and this, I imagine, was effected by means of fo much moifture as was depofited from the air in its ftate of rarefaction, and before it could be drawn from the receiver. To the produdion of this kind of inflammable air, therefore, I was now convinced that water is as eflential as to that from iron.” ,^4 In his analyfis of different kinds of inflammable air, Prieftley’s the DoCtor obferves, that the difference moil com- ?-nalyfis of monly perceived is, that fome of them burn with arynd^of in- lambent flame, fometimes white, fometimes yellow, flamrnafois and fometimes blue ; while another kind always burns air. with an explofion, making more or lefs of a report when a lighted candle is dipped into a jar filled with it. The inflammable air extracted from metals by means of acids is of this laft kind; and that from wood, coal, or other inflammable fubftances by means of heat, belongs to the former. It has alfo been obferved, that thefe kinds of inflammable air have different fpecific gravities ; the pureft, or that which is extracted from iron, &c. being about ten times as light as common air ; but fome of the other kinds not more than twice as light (a). This difference was for fome time attributed to a quantity (a) Here the Doctor’s calculation differs fomewhat from that of Mr Kirwan ; who, in his Treatife on Phlo¬ gifton, He Air Sea. VI. AERO Jnflamma- quantity of fixed air intimately combined with the heavier kinds, fo that it could not be difcovered by lime-water, while the lighteft contained no fixed air at all. In order to afcertain this point, he had recourfe to decompofition ; which was performed by mixing with the inflammable air to be tried an equal quantity of common or dephlogiilicated air, and then confining them in a llrong glafs vefiel previoufly filled either with water or mercury; making afterwards’ an eledlric fpark in fome part of the mixture by means of wires inferted through the fides of the veflel, and nearly meeting within it. Thus he fuppofed that he might be able to determine the quantity of co7niined fixed air, and like- wife the relative quantity of pfilogifton contained irt each of them. The former appeared by vyaihing the air with lime-water after the explofion, and obferving how much of them was obferved ; and the latter by examining the i-efiduum with the teft of nitrous air, and obferving the purity of it. Findii>g, however* that, in fome cafes, more fixed air was found after the ekplofion than could have been contained in the inflam¬ mable air, he was thence led to obferve the generation of % j fixed air from the principles mentioned in the laft fedtion; Fixed air In profecuting this fubject, it was found, that one generated meafure of inflammable air produced by fleam from in the de- metals, and one of dephlogifticated air, fuch as by Uorrofin m'xture with two:meafures of nitrous air was reduced flammable to 0.72 of a meafure, were reduced by explofion to air. 0,6 of a meafure ; the refiduum, by an equal quantity of nitrous air, was reduced to 0.87. With the fame dephlogifticated air, the inflammable air from fining- cinder and charcoal was reduced only to 1.85 of a meafure; but by waftiing in lime-water, to 1.2. The refiduum examined by nitrous air appeared to be of the ftandard of 0.9. In another procefs, the diminution after the explofion was to 1.55, and that after wafhing in lime- water to 0.65, of a meafure; in a third, by explofion to 1.6, and by waftiing to 0.66; and in a fourth, the firft diminution was to 1.6, arid the fecond to 0.6. In this laft experiment there was a generation of an entire meafure of fixed air; and that this had not been con¬ tained originally in any latent ftate in the original fluid, was evident from the fpecific gravity of the in- .flammable air m'ade-ufe of. This, indeed, was one of the heavieft kinds of the fluid : but 40 ounce-meafures of it weighed only two grains more than an equal bulk of ccmmon air; whereas, had all the fixed air found in the refiduum been contained in the original air, it muft have been at leaft one-half heavier. “ Indeed (fays the Do£lor) if any quantity of inflammable air, of about the fame fpecific gravity with common air (which is the cafe with that fpecies of it I am now confidering),- yield fo much as feven-tenths of its bulk of fixed air in confcquence of its explofion with de¬ phlogifticated air, it is a proof that at leaft part of that fixed air was generated in the procefs, becaufe feven-tenths of fuch fixed air would weigh more than the whole meafure of inflammable air,” LOGY. 175 Equal parts of dephlogifticated air and the inflam- Tnfiamma- mable kind produced from fpirit of wine, were redu- |^c Al1'' , ced to one meafure, and by waftiing in lirhe-water to v 0.6 of a meafure.

It contained no fixed air.— Air from brimftone, with an equal part of dephlogifticated air, was diminiihed to 0.6, and no fixed air was found in the refiduum. Its ftandard was 0.95.—With inflammable air from arfenic, the firft re¬ duction was to 1.15, the fecond to 0.95. The ftand¬ ard was 0.82.—With the inflammable air procured by a decompofition of alkaline air, the diminution by ex¬ plofion was to 0.96, and no fixed air was contained in 1 the refiduum; the ftandard of which was 0.8. — In¬ flammable air from ether refembles that from fpirit of wine. The firft diminution was to 1.36, the fecond to 1.2 ; and the ftandard was-1.9.

In ano¬ ther experiment, the firft diminution was fo 0.82, the- fecond to 0.63, and the ftandard of the refiduum MT- ' . . Inflammable air procured by diftilling fome rich- mould in a gun-barrel had a very offenfive fmell, like that procured from putrid vegetables; it contained one- twentieth part of uncombined fixed air. When this- was feparated from it, and the remainder decOmpofed with dephlogifticated air, the firft diminution was to 1.4, the fecond to 0.67, and the ftandard of the refi¬ duum was 0.6.—The air procured from caft-iron has likewife a peculiarly offenfive fmell; and, on this ac¬ count, the Dodlor imagined, that it might contain more phlogifton than common inflammable air, fo as. to abforb more dephlogifticated air than the other,. But this conjeclure did not appear to be well founded;, for on exploding it with dephlogifticated air in the proportions gifton, informs us, that in his experiments he ufed “ inflammable air extracted from clean newly-made filings of foft iron, in the temperature of 590, by vitriolic acid whofe fpecific gravity was 1.0973, and obtained over mercury* having very little fmell, and what it had being very unlike the ufual fmell of inflammable air.”—The weight of this air, when the barometer flood at 29.9, and the thermometer at 6o°, was found to be to that.of. common air as 84.3 to 1.000 ; and, confequently, near iz times lighter. 176 AERO Intiamma- proportions already mentioned, the diminution was I’*6 Air- the fame as with inflammable air produced from the ~v ' malleable kind, viz. 1.56. In thefe experiments, it feemed evident, that at leaft part of the fixed air found after the explofion was pro¬ duced by its means; but the following feem no lefs con¬ vincing proofs, that fixed air may be converted into the inflammable kind, or at leaft that the elements of fixed air may remain in inflammable air in fuch a manner as T36 to be imperceptible. On heating in an earthen re- Fixe.l air tort a quantity of flaked lime, which had long been convertible kept clofe corked in a bottle, it gave air, of which one- mahUUp*1* fifth was generally fixed air ; but in the gun-barrel the fame lime yielded no fixed air at all, but a great quan¬ tity of inflammable air of the explofive kind, like that which is got from iron alone by means of water. As this total difappearance of the fixed air appeared ex¬ traordinary, the Doctor was induced to repeat it feve- ral times with all pofiible care; and the following was the refult of his experiments : Three ounces of flaked lime, which had for fome time been expofed to the open air, heated in an earthen tube, yielded 14 ounce- meafures of air, of which only two and an half remain¬ ed unabforbed by water ; the refiduum was flightly in¬ flammable, but not perfectly phlogifticated. Three ounces of the fame lime, heated in a gun-barrel, gave 20 ounce-meafures of air, all of which was inflam¬ mable, and no -part fixed. It was expedted, how¬ ever, that fhe fixed air would have appeared on the de- compofition of this inflammable air with the dephlogif- ticated kind* but after this procefs, it appeared to be exactly fuch inflammable air as is procured from metals by the mineral acids, or by fteam ; the diminution of the two kinds of air being exaftly the fame : and tho’ fome fixed air was found in the refiduum, it was no more than is ufually met with in the decompofition of inflammable air procured by means of fpirit of fait.— Suppofing that the two kinds of air might incorporate, when ©ne of them was generated within the other, a gun-barrel was filled with fixed air, and the clofed end of it put into a hot fire. Inflammable air was inftant- ly produced ; but when the fixed air was feparated from it, it burned like inflammable air with which no other kind had ever been mixed. On heating iron-turnings in five ounce-meafures of fixed air, the quantity of it was increafed about one ounce-meafure, and there remained one and three-fourths unabforbed by water. The experiment was repeated with the fame refult; and it was farther obferved, that though the inflammable air procured in this manner did not appear by the teft of lime-water to contain any fixed air, yet when it was decompofed by firing it with an equal quantity of dephlogifticated air, the refiduum contained one-third of fixed air. The diminution was to 1.45. Hence the Doftor conjeftures, that though, in fome cafes, the fixed air appears to be generated by the decompofition of dephlogifticated and inflammable air, yet that inflammable air, when thus produced in oontaft with fixed air, may combine with it, fo as to be properly contained in it, and in fuch a manner that it cannot be difeovered by lime-water. Inflammable air, when produced in the drieft way poflible, is exceedingly light, as has been already ob- ferved i but Dr Prieftley has found, that by ftanding N° 5- 3 LOGY. Sedt. VI. on water, a very confiderable increafe ’is made in its Inflamma- fpecific gravity; fo that from being ten or twelve times hh Air. ^ lighter than atmofpherical air, it foon becomes only feven times lighter. This great propenfity to unite Great pro- with water is alfo taken notice of by Mr Kirwan; who [ entity of tells us, that the bulk of innflammable air obtained o- ver water with the afliftance of heat towards the end, unite* with was one-eighth greater than when produced over mer- water, cury ; but that the weight of it in the former cafe was only eight or nine times lefs than common air. “ From 85 cubic inches of inflammable air obtained over water, I extra died,” fays he, “ by oil of vitriol ex¬ pofed to it for 55 hours, two grains of water; and* though undoubtedly there is an error in all thefe expe¬ riments, yet there can be little doubt but this inflam¬ mable air contained one-half its weight of water. The inflammable air, by the fubtra&ion of its water, loft its fmell, but continued as inflammable as ever; andthere¬ fore there is no reafon to think that it was decompofed, or that water is any way eflential to it.” This conclufion is directly contrary to that of Dr Prieftley, that water is an effential ingredient in the compofition of inflammable air; nor do the experi¬ ments of the latter, already recited, feem to have had any weight with him, as he concludes his Treatife on Phlogifton in thefe words. “ To the proofs I have Mr j^ir- heretofore given, that inflammable air and phlogifton wan’s con- are the fame fubftance, juft as ice and the vapour ofclslhn con- water are called the fame fubftance, no objedion of any weight has fince been made. Some have thought <4 ;nj]am_ that I ftiould have included the matter of heat or ele- mable air. mentary fire in the definition of inflammable air: but as fire is contained in all corporeal fubftances, it is per- feftly needlefs, except where bodies differ in the quan¬ tity of it they contain ; and in this refpeft I exprefsly mentioned its difference with phlogifton to confift.— Others, attending to the quantity of water contained in inflammable air, have fuppofed it to be an effential ingredient in the compofition of this air, and have call¬ ed it phlogifticated water; but they may as well fup- pofe water to be an effential ingredient in common air, or fixed air, and call this laft acidulated water: for in¬ flammable air, equally as other airs, may be deprived of its water without any limitation, and yet preferve all its properties unaltered; which ftiows the prefence of water to be no way effential to it. Laftly, others have thought, that it effentially requires an acid or an alkali, or fome faline fubftance, for its bafis; as if there were any more repugnance in the nature of things, that phlo¬ gifton fhould exift in an aerial ftate without any bafis, than marine air, alkaline air, or dephlogifticated air; when it is evident, that an aerial ftate requires no more than a certain proportion of latent heat: but the pro- du&ion of inflammable air from iron by means of di- ftilled water, without any acid or fait, has effeftually done away any fufpicion of that fort.” On the other hand, Dr Prieftley informs us, that p'r;e4_ “ inflammable air feems now to confift of water and ley’? con- inflammable air : which, however, feems extraordinary, clufion._ as the two fubftances are hereby made to involve each other; one of the conftituent parts of water being in¬ flammable air, and one of the conftituent parts of in¬ flammable air being water ; and therefore, if the expe¬ riments would favour it (but I do not fee that they do fo). I Seel. VI. O Inflamma- fo), it would be more natural to fuppofe, that water, . k’6 Air~ ; like fixed air, confifts of phlogifton and dephlogifticated v air, in fome different mode of combination. “ There is an aftonilhing,variety in the different kinds of inflammable air, the caufe of which is very im- perfeftly known. The lighteft, and therefore probably the pureft kind, feems to confift of phlogifton and. wa¬ ter only. But it is probable that oil, and that of dif¬ ferent kinds, may be held in folution in feveral of them, and be the reafon of their burning with a lambent flame, and alfo of their being fo readily refolved into fixed air when they are decompofed by dephlogifticated air; though why this fliould be the cafe, I. cannot ima- sine- “ When inflammable and dephlogifticated air are burned together, the weight of the water produced is never, I believe, found quite equal to that of both kinds of air. May not the light, therefore, emitted from the flame, be part of the phlogifton of the inflammable air united to the principle of heat ? And as light accom¬ panies' the elettric/park, may not this alfo be the real accenfion of fome phlogiftic matter, though it is not eafy to find the fource of it ?” The Frepch chemifts, who deny the exiftenee of phlogifton, are of opinion, that inflammable air is a fimple uncompounded element; but for a more full 140 difeuffion of this fubjeft, fee the article Phlogiston. Abforption Inflammable air is abforbed by water in confiderabk mable'air but by the application of heat may be expel- by water, led again in equal quantity. By agitation in water Dr Prieftley was formerly of opinion that this kind of air might be rendered as good as common air; but this undoubtedly proceeds from the atmofpherical air tranf- mitted by the water, as is the cafe with phlogifticated air mentioned in the laft feftion. After a quantity of water, which had abforbed as much inflammable air as it could, had been fuffered to ftand a month, it was ex¬ pelled by heat, and found to be as ftrongly inflammable as ever. The water, after the procefs, depofited a kind of filmy matter; which he fuppofed to be the earth of the metal that had been employed in produ- 141 cing it. Its effects Plants in general grow tolerably well in inflammable iTancT" a”"’ an<^ tbe willow plant has been obferved to abforb anima[ life great quantities of it. Its inflammability is not dimi- nifhed by the putrefaction of animal fubftances, nor does their putrefaftion feem to be retarded by it. Ani¬ mals confined in it are killed almoft as foon as in fixed . air : but infeCts, which can live a confiderable time in phlogifticated air, live alfo a confiderablr time in this kind of air ; but at laft they become torpid, and appear to be dead, though they will ftill recover if removed into the open air. Mr Cavallo relates, that the Abbe Fontana, having filled a large bladder with inflammable air, began to breathe it in his prefence ; after having made a very violent expiration, in which cafe the ef- fedls are moft -powerful. The firft infpiration produced a great oppreffion in his lungs, the fecond made him look very pale, and the third was fcarce accomplifhed when he fell on his knees through weaknefs. Birds and I4i fmall quadrupeds, inclofed in fmall veffels of this air, Has little died after a very few infpirations. Laftly, inflammable refra&ive air appears to have a fmaller (hare- of refradtive power power. than common air ; for Mr Warltire informs us, that having placed an hollow triangular prifin, of which the Vol. I. Part I. LOGY. 177 angle was 72 degrees, fo as to half cover a large obje&-Inflamma- glafs in one of Mr Dollond’s perfpe&ives, and fo turn- , ble Air~ , ed round as to make the frame of a window, at the di- v ftance of 1280 feet, feen partly through the prifm and partly through common air, appear undivided. The inflammable air was then blown out of the prifm, but no part of the apparatus was moved; when the frame of the window feen through the object-glafs and the prifm as before, feemed to feparate about four inches. I43 The inflammability of this fpecies of air has given Schemes ts occafion to various projefts concerning it; fuch as thaten'P'°y u of employing it to give light and heat; and lamps have beendeferibed, which maybe lighted by the elettricfparki 1 in the night-time. By its means alfo very pretty arti¬ ficial fires are made, with glafs tubes bent in various directions, and pierced with a great number of fmall apertures. The inflammable gas is introduced into thefe tubes, from a bladder filled with that fluid, and fitted with a copper cock. When the bladder is pref- fed, the inflammable air, being made to pafs into the tube, iffues out of all the fmall apertures, and is fet on fire by a lighted taper. None of thefe contrivances, however, have ever been applied to any ufe ; and the fcheme of Mr Volta, who propofed to fuhftitute its ex- plofive force inftead of gun-powder, is found infuffi- cient, on account of the weaknefs of the explofion, ex-. cept when the two airs are fifed in very great quantity, which would be incompatible with the fmall bulk ne- ceflary for warlike engines. Sect; VII. Sulphurated Inflammable Air. This was difeovered by Dr Prieftley at the time when he was engaged in the experiments of which fome account has been given in the laft feCtion,' of tranfmit- ting the fteam of water and other fluids through red- r44 hot tubes containing fome folid material. Having, a- Firft pro- mong others, treated manganefe in this manner, by cured from flopping one end of the heated tube with a cork be- manganefe. fore the fteam was applied, he received forty ounce- meafures of air, of which one-fixth was fixed air and the reft of the ftandard of 1.7, lambently inflammable. Having then opened the other end of the tube in or¬ der to admit the fteam, air was produced more co- pioufly thap.before. Of 50 ounces of this air, one- feventh was fixed, and the reft, of the ftandard of 1.8, explofively inflammable. The laft portions were very turbid; and the fmell, efpecially that of the laft por¬ tion, was very fulphureous, tinging the water of a very- dark colour, by depofiting in it a quantity of blackifti water. However, the air itfelf became prefently tranf- parent, and had no other appearance than that of any other kind of air. . On looking at the jar in about ten minutes after, it was quite black and opaque ; fo that nothing could be feen in the infide of it. Filling after¬ wards another jar with the fame kind of air, in order to obferve the progrefs of this uncommon phenomenon, he found, that when the water was well fubfided, black fpecks began to appear in different places, and, ex¬ tending themfelves in all directions, at length joined each other, till the whole jar was become perfectly black, and the glafs opaque. When this was done, he transferred the air into another jar ; and it foon pro¬ duced a fimilar effedt upon this, though it never became Z fo 178 AERO Inflatnma- f0 black as the jar in which it had been firft recei- ble Air. ve(j> jt alf0 frequently happened, that only the lower ' ~v part of the jar would become black, as if the matter with which it was loaded had kept fubfiding, though invifibly, in the mafs of air, and occupied only the lower regions, leaving the upper part entirely free from it. On expofing to the open air the velfels thus turn¬ ed black, the colour prefently difappeared, and a yel¬ low or brown incruftation was left upon it. The fame change took place when the veffels were inverted in, water, in order to obferve the alteration of the air with¬ in them ; but on examining this air, no feniible change was perceived. In feme cafes, indeed,, he "thought the air was injured, but it was much lefs fo than he had expefted. After depofiting the black matter, the air ftill retained its fulphureous fmell, and he did not i* *45 magine that- it would ever leave it entirely, frorr^ivor On trying other fpecimens of manganefe, no air of mekedTn^ ^is kind was obtained; but fome time after, having vitriolic occafion to make a large quantity of inflammable air, acid air. he ufed, inftead of frelh iron, fome that had been al¬ ready melted iq vitriolic acid air. Diffolving this with a confiderable quantity of frefh metal in diluted vitrio¬ lic acid, he found that the water in which the air wa’s received became very black, and depolited more fedi- ment than had appeared in the experiment with the manganefe. The jars were as. black as ink, but be¬ came yellow on expofure to the air as before ; fo that there could be no doubt of its being the fame thing he had got before. On burning a quantity of it, this kind of air appeared to contain fome vitriolic acid, the balloon being filled with a very denfe white fume, which rendered the water fenfibly acid to the tafte. On de- compofing it with dephlogifticated air, however, he found the diminution exaftly the lame as when com-, mon inflammable and deplogifticated air were ufed ; fo that it appeared to contain neither more nor lefs phlo-. gifton than the other ; only there was a fmall quantity of fixed air produced, which is never the cafe with Common inflammable air from vitriolic acid and iron. When the fulphurated inflammable air is received o- ver mercury, very little black matter is produced on the jars; and it is remarkable, that though the black matter collefted on them, when the air is taken through water, foon. grows yellow upon expofing it to the air, it is not the cafe with that which remains in the wa¬ ter ; it adheres to the evaporating vefiel in form of a- black incruftation,. which does not burn blue until it has been digefted in the nitrous acid, which deprives it of its fuperfluous phlogifton, and leaves it. both of the colour, and. fmell of fulphur. S ecT. VIII.. Of Alkaline Air. This was procured by Dr Prieftley, in the begin¬ ning of his experiments,, from common fpirit of fal- ammoniac with quicklime, or the materials from which it is made, kfe did not at that time profecute the difeovery farther than by impregnating water with it; by which means he could make a much ftronger alka¬ line fpirit than any to be met with in the Ihops.. His method of procuring it was by mixing one part of pounded fal-ammoniac with three parts of flacked lime; and for common experiments the fame quantity of ma¬ terials would laft a confidorable time. LOGY. Sed.VIIL This kind of air, when pure, is inftantly fatal to ani- Alkaline mal life, and extinguiihes flame ; though, when mixed Air> , with common atmofpherical air, it is flightiy inflam- v mable,. and alfo medicinal in faintings and other cafes p I4^. of debility. A candle dipped into a jar of this air 0f alkaline is.extinguilhed ; but juft before the flame goes out, it air. is enlarged by the addition of another flame of a pale yellow colour, and fometimes a weak flame fpreads for a confiderable way, or even through the whole body of the alkaline air. The eleftric fpark taken in it ap¬ pears of a red colour. Every fpark taken in it aug¬ ments its bulk, and by degrees turns the whole into inflammable air.. It is readily abforbed by water, as has been already obferved, and diffolves ice almoft as faft as an hot fire. On confining fame water impreg¬ nated with alkaline air in a glafs tube, and thus expo- fmg it to a ftrong heat in a fand-furnace for fome days, he obferved that a white fediment or ineruftation was formed on the furface. The Do&or remarked, that bits of linen, charcoal, and fponge, admitted into a quantity of alkaline air, diminilhed it, and acquired a very pungent fmell; efpecially the fponge, a bit of which, about the fize of an hazle-nut, abforbed an ounce-meafure. It is remarkable that copper, w'hich is fo, eafily corroded by the common volatile alkalis, is not affefted by alkaline air. The fpecific gravity of this kind of air is, by Mr Kirwan, determined to be to that of common air as 600 to 1000; though, as he juftly obfervea, this muft differ very confiderably accor¬ ding to the quantity of moifture it contains. J47 In profecuting his experiments on alkaline air, Dr Proofs of Prieftley concluded that it contains phlogifton, both its conta.'n- from its being convertible into inflammable air by elec inff Pe¬ trie explofions, and likewife from its reviving the cal-®1 on* ces of metals. In attempting to afeertain the quan¬ tity of lead revived in alkaline air, he met with two difficulties; the firft, on account of fome part of the calx being blackened and imperfeftly revived ; the fe- cond, that the lead completely revived was diffolved by the mercury employed to confine the air. To prevent this laft inconvenience, he put the powdered mafficot (the fubftance he chofe to employ on this occafion) in¬ to fmall earthen cups, contriving to place them with- their mouths upwards, in fuch a manner, that when the lead was revived by means of a burning lens, it would remain in the cup, and not mix with the mer¬ cury which fupported it. The proportions of metal then revived, were fix grains of lead in three ounce- meafures, 16 *- in three meafures and an half, 13 in two- and an half, and 12 in three and three-fourths; but thef experiment on which he laid the greateft ftrefs, was that in which 26- grains of lead were revived in y? ounce- meafures of alkaline air. In this proportion, 100 onnee-meafures of alkaline air would revive 352 grains of lead ;. but an equal quantity of inflammable air from, iron would have revived 480 grains of metal. This deficiency appeared fomewhat furprifing to the Doftor, confidering that alkaline air is refolved into more than twice its bulk of the inflammable kind; though it is poffible, that inflammable air from , iron may contain more phlogifton than that into which alkaline air is re-- folvable. On heating red precipitate in alkaline air, the mer¬ cury was revived as in other cafes, and a confiderable quantity of water was produced, though none appears Oil : 2. Sea. VII. AERO Alkaline on reviving it with common inflammable air. “ It has Air. even (fays he) run down in drops in the infide of a ' veflel which contained five ounce-meafures of the air; and a confiderable quantity of dephlogifticated air was found in the refiduum.” On throwing the focus of the lens on red precipitate, inclofed in this kind of air, till three meafures of it were reduced to two, water was i produced as ufual, and the ftandard of the refiduum was 1.7. In another experiment, a violent explofion took place before he could obfefve whether any water • 148 was produced or not. !feonverfion In examining the phenomena which attend the con- of alkaline verfion of alkaline air into the inflammable kind, the Krlv1' Do&Qr was induced to believe that it was occafioned by heat alone, without the concurrence of light. The effects of the former were firft perceived on heating feme ochre of iron in alkaline air ; when, though the matter turned black, as in an incipient reduction of the metal, he found a confiderable increafe of quantity in¬ stead of decreafe in the air, as he had expedted ; and, on examining the quality of it, he found that it con¬ tained no fixed air, but was entirely inflammable. With feales of iron a fimilar enlargement was perceived; but in this way he could never increafe the quantity to more than double that which had been originally employed, and even after this the whole fmelled ffrongly of vola¬ tile alkali; the iron had undergone no change. The Dodtor now, concluding from thefe experiments that the change of alkaline into inflammable air was produced by this caufe alone, proceeded to repeat the experiment, by heating in the alkaline air bits of dry crucibles, or of earthen retorts, which had been jult before expofed to very great heats, fo that they could not be fuppofed to give out any air themfelves, and therefore could only ferve to communicate a ftrong heat to the alkaline air; and in thefe experiments the refult was the fame as when ochre and iron were made ufe of. The bits of white earthen ware were always turned black ; but finding the fame effeft of augment¬ ing the air and giving it an inflammable quality, though he ufed the bit of crucible over and over again, he was thoroughly conrinced that the change was effedled by heat alone. In all thefe experiments, however, with a burning- glafs, as a ftrong light was alfo concerned, he heated a quantity of alkaline air in a green glafs retort, receiving in a glafs tube, filled with water, all the air that could be expelled from it by heat. At firft it was all abforb- ed by the water, being merely alkaline air expelled by the rarefaction ; but when the bulb of the retort be¬ came red-hot, he found that the bubbles driven out were not wholly abforbed, and at laft none of them were fo. Thefe were altogether inflammable ; fo that no doubt remained of the change being produced by heat alone, without any intervention of light. It was farther obferved, that whenever the alkaline air was changed into inflammable by means of bits of retorts or crucibles containing clay, they always be¬ came black during the procefs. He inclined therefore to fuppofe, that fomething might be depofited from the air which might attach itfelf to the clay. “ In¬ deed, (fays he) if this was not the cafe, I do "hot fee why the clay Ihould become black ; though, perhaps, part of the fame phlogifton which forms the inflam- tnable air may be attracted by the red-hot clay, with- L o G V. 179 out there being any proper decorapofition of the air. Nitrous Air. That this is the cafe feems probable from an experi- v ^ ment in which I ufed porcelain inftead of common earthen ware ; which did not become black in the pro¬ cefs, though inflammable air was produced.” ,40 In fome of Dr Prieftley’s experiments, he had oh-Volatile al- ferved that iron, which had long rufted in nitrous air, gave out a ftrong fmell of volatile alkali. This extra- nitrous air ordinary phenomenon, however, was only perceived and iron, where the nitrous air and iron had been in contaft for a very long time; but he found that it was much foon- er produced by making ufe of a weak folution of cop¬ per ; by putting iron into which he obtained that fpe- cies of nitrous air called dephlogifticated. A phial con¬ taining fome of this iron, which had been ufed only once for the purpofe juft mentioned, having been kept clofe corked for about two months, was accidentally broken ; when fome pieces of the iron were found co¬ vered with a green cruft, and thefe had a ftrong fmell of volatile alkali.

Thus, when it is mixed with metals, or animal or ve¬ getable fubftances, nitrous air is produced in great quantities; but very fparingly when treated with me¬ tallic calces, earths, or other matters which are faid to contain little or no phlogifton. All the metals, ex¬ cepting gold, platina, and regulus of antimony, which are not foluble in the pure nitrous acid, yield nitrous air on being treated with it 5 and even from thefe, when diffolved in aqua regia, fome quantity of this air may be obtained. Every metal, however, does not yield it in equal quantity, with equal facility, or e- qually good. Silver, copper, iron, brafs, bifmuth or nickel, when put into nitrous acid, yield this air in confiderable quantity: Mercury yields it but flowly without the application of heat, though no great de¬ gree of it is neceffary. Copper and iron, efpecially the latter, require the acid to be cautioufly applied on ac¬ count of the violent emiflion of fumes. Gold, platina, and regulus of antimony, when put in aqua regia, yield nitrous air pretty readily; but lead yields it in fmaller proportion than any other metal, and zinc does the fame among the femimetals, the elaftic fluid produced from it being moftjy phlogifticated air. In the produftion of this kind of air, great differen¬ ces are perceived by a diverfity in the ftrength of the acid. Thus, if we diffolve copper in ftrong nitrous a- cid, no nitrous air is produced, though the fame ma¬ terials will yield air in great quantity by the mere af- r^I fuflion of water to dilute the acid. This is very pro-Why ftroug perly explained by Doftor Prieftley, from the property citrous acid that the nitrous acid has of attracting phlogifton, ‘ts. which is evident from what happens in the folution 0fnitrousai * mercury. When ftrong fpirit of nitre is poured upon this metal, the folution foon begins, and is very rapid, yet not a Angle bubble of elaftic fluid is produced ; but in a ftiort time the acid next to the'mercury is chan¬ ged of an orange colour, which is an indication of its having acquired phlogifton, probably from the nitrous Z 2 air i8o AERO NitronsAir. aiV which is decompofed the moment it is formed, and ' before its particles are united into vifible bubbles. The bubbles of air indeed break througlr the coloured acid, but they-difappear the moment they come in contadl with the pale-coloured acid. As foon as the whole quantity of acid has affumed the orange colour, nitrous air efcapes from it in confiderable quantity; but the mixture of water deprives the acid of its power , of de- • compofing nitrous air. The ftrong and pale-coloured nitrous acid ought to be diluted with at leaft two or three parts of water to one of the acid, for the eafy production of nitrous air from copper and mer¬ cury. In common experiments, no other degree of heat is neceffary than that produced by the effervefcence itfelf, except mercury be ufed, which requires the application of fome degree of heat; but when the metal expofes a very great furface to the acid, as is the cafe when the filings of the metal are ufed, the effervefcence and production of nitrous air are often much quicker than can be conveniently managed. The moft proper me¬ thod of producing nitrous air, however, is explained 152 in the laft fcCtion of this treatife. Properties Nitrous air by itfelf is equally tranfparent and in- of nitrous vjflble with common air, excepting at its firft produc¬ tion, when it is fomewhat coloured, owing to a little • fuperfluous nitrous acid, or to fome earthy particles which are carried up with it. Its fmell refembles that of nitrous acid, or indeed is' the very fame ; becaufe, in pafiing through the common air to our noftrils, it is decompofed, and converted into nitrous acid. The fame is to be faid of its taite ; though Mr Fontana, who tailed it without any contaft of external air, af¬ firms that it has no tafte whatever. The method in which he afcertained this fa6t was as follows. Having firft introduced the nitrous air into a bottle of elaftic gum in water, as is done with glafs bottles, he brought his mouth, (hut, while the neck of the elaftic-gum bottle was under water, near the neck of it; and then, by preffing the bottle, introduced the nitrous air into his mouth. The experiment, however, is by no means void of danger; for if the perfon happens to draw any quantity of this air into the lungs, he may be nearly fuffocated, as nitrous air is exceedingly noxious. In performing of it, he recommends to exhauft the mouth entirely of common air, though he does not inform us how this can be done; nor indeed is it eafy to con¬ ceive the poffibility of doing fo. Though nitrous air extinguilhes flame, it may by certain proceffes be brought in to fuch a ftate that a candle will burn in it with an enlarged flame; and it becomes what Dr Prieftley calls dephlogijiicated nitrous air, which is treated of in the next fe&ion. It is remarkable, however, that when a candle is extin- guiftied, as it never fails to be in common nitrous air, the flame feems to be a little enlarged about its edges by the addition of another bluiih flame before the for- >53 mer g?es out.

Dr Prieftley informs us, that having carefully pumped all the air out of a quantity of rain-water, letting it Hand 24 hours in a good vacuum, and then impregnating it with nitrous air, he inftantly expelled it again by boiling, when he obtained only about one fourth part of it, though fufficiently pure, and with¬ out any mixture of fixed air. Water may alfo be de¬ prived of the nkrous air it contains, though it does not freeze quite fo readily when impregnated with this air as in its natural ftate. Nitrous air is abforbed by ftrong oil of vitriol nearly in the fame quantity as by water; the acid acquiring a purple colour, by reafon of the phlogifton contained in the piteous air. The ftrong nitrous acid abforbs it in great quantity; and becomes fmoking, orange co¬ loured, and afterwards green, on account of the phlo¬ gifton contained in it. Marine acid imbibes but a fmall quantity, and very flowly, acquiring at the fame time a light-blue colour. Both nitrous, air and com¬ mon' air phlogifticated by it are meliorated by agita- tation in nitrous acid. Nitrous air is abforbed in confiderable quantity by radical vinegar, and the concentrated vegetable acid.— Solution of green vitriol imbibes it in much greater quantity than water, and acquires a black colour; which, however, foon goes off by expofure to the common air. Its tafte alfo becomes acid.—Very little is abforbed by cauftic alkalis. Oil-olive flowly ab¬ forbs a confiderable quantity, but oil of turpentine abforbs much mdre. By a little agitation, it will imbibe more than ten times its quantity of nitrous air ; acquiring at the fame time a yellowilh or orange colour, and becoming a little glutinous. The part which is not abforbed appears to be converted into phlbgifticated air.—Ether and fpirit of wine abforb it very quickly’, but no nitrous air is obtained by the application of heat after they have abforbed it. It is greatly diminilhed by oil of turpentine, liver of fulr phur, and pyrophorus ; all of which leave it in a phlo¬ gifticated ftate. It is alfo diminilhed and phlogiftica¬ ted by being kept in a bladder, alternately expofed to moifture and drynefs. Nitrous acid air has the fame effed. One of the moft remarkable properties of nitrous Dimjnffliea air, is its diminution with dephlogiftieated air; by dephlogifti. which means it becomes a tell of the quantity of thatcatc<*air* kind of air contained in the atmofphere. With pure dephlogiilicated air, the diminution is almoft to no¬ thing, at the fame time that fome quantity of nitrous acid is reproduced by the decompofition of the nitrous air; but as our atmofphere is always mixed with a confiderable quantity of phlogifticated air, on which nitrous.

This property', it was thought, might have been extremely ufeful on many occafions; but Dr Prieftley, after a number of experiments on the fubjeft, concludes in the following manner. “ Ni¬ trous air will indeed preferve meat from putrefaclion ; but after long keeping, it becomes very offenfive both to the noftrils and palate, though the fmell is not alto¬ gether that pf putrefaction ; and indeed the fubftance continuing quite firm, it could not be properly putrid. —Having, formerly experienced, the remarkable anti- feptic power of nitrous air, I propofed an attempt to preferve anatomi'cal preparations, &c. by means of it; but Mr Key, who made the trial, found, that, after fome -months, various animal fubftarices were fhrivel- led, and did not preferve their forms in this kind of i?6 air.” . . . . ’ Specificgra- The fpecific gravity of nitrous air, as well as of vity oi tii- other kinds, has been afcertained by Mr Kirwan.

In one experiment half an ounce of nitrous, air was reduced, an lefs than half an hour, to one^juar ter of its bulk. One-fourth of the refiduum was ftill nitrous, and the reft phlogifticated. Taking the elec¬ tric fpark in a quantity of nitrous air till it was dimi- niflied to one-third, the whole was completely'phlogi¬ fticated, not affefting common air at all, and extinguilh- ing a candle. A white matter was formed with the mercury over which the fpark was taken, which made the water admitted to it extremely turbid. In another procefs, the ele&ric fpark was taken in a quantity of nitrous air till it could be no more diminifhed, when it * was reduced in bulk in the proportion of iol to 24. Letting it ftand all night upon the mercury, it was in- creafed in the proportion of 11^- to 24 ; feemingly by the acid uniting to the mercury and generating more nitrous air, fince it had that fmell. No water appear¬ ed after the procefs; and the water admitted to it ac¬ quired no acid tafte, but an aftringent one like that of water impregnated with nitrous air. There #as a white powder formed, as in the former experiments.—To try if it were poflible to make water imbibe the acid from the nitrous air, the eleftric fpark was taken in it, with a fmall quantity of water over the mercury. But even this water did not acquire any acid tafte, but only air aftringent one.” The Do&or concludes his experiments on this fub- iect with a conje&ure, that the phlogifton, and neither the heat nor light of the eleftric, contributes to the de- compofition of the nitrous air. As his final fentiments on the matter, however, are merely conjecture, without any certain experiments to confirm them, we fiiall here refer the reader to -his SeCtion on Theory, at the end of his fixth volume of Experiments, &c. Sect. IX. Of DephlogijlicatedNitrous dir- This fpecies differs from common nitrous air in be- *6o ing able to fupport flame, though it ftill continues fatal How pro- t0 anijnal life. Common nitrous air may be converted £ure ’ into the dephlogifticated kind by particular proceffes ; though, when zinc is diffolved in the-nitrous acid, if .the air be taken at different times, that which comes about the middle, or rather the latter end of the pro¬ cefs, will be of this kind ; in which it not only fup- ports the burning of a candle, butAhe flame is enlarged (fometimes to four or five times its original bulk) by the addition of a weaker and bluiih flame round the former ; and this burning is fometimes accompa¬ nied with a crackling noifej as if the candle was burn¬ ing in dephlogifticated air. It may alfo be obtained in fome part of the procefs of procuring nitrous air from iron, though with this metal the fuccefs is uncer¬ tain ; but tin yields a conliderable quantity of it. By expofing iron to nitrous air, it may be fo far dephlo¬ gifticated as. to admit a candle to burn in it. Dr Prieft- ley filled an eight-ounce phial with, nails, and then with mercury and difplacing the mercury with nitrous air, left the phial inverted in a quantity of the fame fluid. Two months after, the nitrous air was found to be changed in fuch a manner as to admit a candle to burn in it with its natural flame; and by continuing ftill - longer in contact; with the iron, a candle would burn in it with an enlarged flame. Thefe changes, however, LOGY. Sea. IX. are very irregular, fo that theyfeldom produce the like Dephlogif- 1 effects with the regularity one might expeft. J)r dcated Ni- ; Prieftley once found, that by the contaft of iron introus ^ ir* , i quickfilver, it was fo changed as to be fired with an explofion like a weak inflammable air; whilft another quantity of nitrous air, which had been treated in like - manner for about the fame length of time, only ad¬ mitted a candle to burn in it with an enlarged flame. 1($r ; In that fc&ion of .his laft volume in which the Doc- Component tor treats of this kind of air, he obferves, that water is Parts . ca§ **n£> k’ts of clean crucibles or retorts in this kindLof the nature a‘r>’t feemed to approach in quality to common atmo- of atmo- fpherical air ; and the effects were always found to be ipherical the more confiderable the longer the procefs was con- |air‘ tinued. On attempting, however, to determine whe¬ ther this change in the conftitution of dephlogifticated nitrous air was occafioned by means of heat or light, he heated it in earthen tubes; but found, that though thefe were glazed both on the outfide and infide, and feemed perfectly air-tight both before and after the ex¬ periment, the air had efcaped. By the eleftric fpark it was rendered wholly immifcible with water, and brought to the ftandard of 1.45 ; fo that the Doctor had no doubt of its being refpirable. Yet this kind of air, though it admits a candle to burn fo well in it, will not kindle pyrophorus, though the nitrous air from which it is produced would inftantly fet it on fire. t6s How pro¬ cured. Sect. X. 0/ Vitriolic, Nitrous, Marine, and other Acid Airs- § I. Vitriolic acid Air.—This is always a combina¬ tion of vitriolic acid with phlogifton, and confequently may be procured from any mixture of that acid in its highlyconcentrated Rate with phlogiftic matters. Hence it is obtained from all the metals, gold and platina ex¬ cepted, on boiling them with ftrong oil of vitriol. It is alfo procurable from the fame acid rendered black by any phlogiftic matter. No greater heat is required to expel this kind of air than that produced by the flame of a candle. It is the heavieft of all aerial fluids,, next tofluor acid air, being to common air 33 2265 to 1000. Dr Prieftley informs us, that a quantity of vitriolic acid thus impregnated with phlogifton, will yield many times more air than an equal quantity of the ftrongeft fpirit of fait.—When the vitriolic acid air is produced in great plenty, the top of the phial in which it is gene¬ rated is commonly filled with white vapours. The air has .alfo the fame appearance as it is tranfmitted through LOGY. 183 the glafs tube; and it is fometimes difcoverable in the Nitrous recipient. When fuch fubftances are put to the oil ofAci;i Air‘ , vitriol as caufe a great effervefcence with that acid, care "v fhould be taken to add them by very fmall quantities at a time, and likewife to apply the heat by very flow degrees, left the rapid production of air, and the heat attending it, fhould break the veffels. It is moft equa¬ bly produced by ufirtg ftrong oil of vitriol and char¬ coal ; but in moft cafes the production of vitriolic acid air is attended with that of inflammable, and fometimes fixed or phlogifticated air. With ether about one- half of the firft produce is inflammable ; but’the quan¬ tity leffens as the procefs goes on. The DoCtor ob¬ ferved, that, when quickfilver was ufed, the acid was not turned black, as in other experiments of the like nature. He alfo obferved, that iron yielded a little in¬ flammable air together with the acid gas ; but that the elaftic fluid produced when zinc was ufed, contained about two parts of inflammable and one of acid air. Copper, filver, and lead, when heated in vitriolic acid, yield the pureft vitriolic acid air, without any mixture of inflammable air; but the lead yields only a very fmall quantity, and requires a great degree of heat. It is procured in the greateft abundance from the fumes of burning fulphur, and is then called the volatile vi¬ triolic, or fulphureous acid; for an account of the pro¬ perties of which, fee Chemistry, [Index). jgg, $ 2. Of Nitrous Acid Air.—This is the pure nitrous How ob-- acid by itfelf, without any addition of phlogifton. It tained. is procured by heating the ftrong fpirit of nitre in a phial, and then receiving the vapour in glafs veffels filled with quickfilver. It is, however, extremely difficult, or rather impoffible, to preferve it for a length of time ,5^ by means of any fluid hitherto known. Water abforbs Cannot bs it immediately, and quickfilver is corroded, and pro- preferved duces nitrous air. “ But (fays Dr Prieftley) tho’ the^^f®”5 acid vapour very foon unites with the quickfilver, yet, the jar in which it was received being narrow, the fa line cruft which was formed on the furface of the quick¬ filver, impeded the action of the acid upon it till I had an opportunity of admitting water to the air I had produced, and of fatisfying myfelf, by its abforp- tion, of its being a real acid air, having an affinity with water fimilar to other acid airs.” The moft remarkable property of this vapour is, that Affumes a its colour may be made more or lefs intenfe by the red colon* mere circumftance of heat. It may be confined glafs veffels with ground-ftoppers, or in tubes hermeti¬ cally fealed, and thus expofed to the adlion of heat : in which cafe it will be found, that the colour of the vapour becomes confiderably more intenfe in propor¬ tion as the glafs veffel containing it is more or lefs heated; and that, on the contrary, the intenfity of the colour diminiflies as it is cooled. “ It feems pro¬ bable (fays Dr Prieftley), that if this vapour was not confined, but had room to expand itfelf, it would be¬ come colourlefs with heat. This at leaft is the cafe when it is combined with water. The phenomena f. refer to are very common in the procefs for making dephlogifticated air, in which I firft obferved them. But the fame things are obfervable in the procefs for producing any other kind of air in which much fpirit .of. nitre is made ufe of; and likewife conllantly in the common procefs for making fpirit of nitre itfelf. It is, that when the heat is moderate, the vapour within 184 AEROLOGY Sett. X. MariHe the glafs tube or retort is red; but that, as the heat Acid Air. , jncrcafes> {t becomes tranfparent.” The Dodbor ha- 169 ving obferved that red lead, impregnated with nitrous Its effe6h vapour, may be preferved a long time without deli- -®n red-lead, quefcing or lofing its acid, made life of a compofition of this kind for procuring the nitrous vapour with which he filled his tubes. By imbibing this vapour the minium loft its red colour arid became white. “ I put (fays he) a fmall quantity of this white minium into a glafs tube clofed at one end ; then, holding it to the fire, make it emit the red vapour till the whole tube is filled with it; and having the other end of the tube drawn out ready for clofing, asfoon'as the vapour begins to iffue out of that end, I apply my blowpipe and feal it. By this means I conclude that the tube is filled with a pure red vapour, without any mixture of nitrous air, and perhaps common air alfo.” For a further' accourit of the properties of nitrous acid air, fee Chemistry, (Index.) Of Marine Acid ylir.—-The marine acid, by heat, may be refolved into a permanently elaftic and tranfparent invifible vapour, w’hich, however, is more ,j^0 eafily preferred in its aerial ftate than nitrous acid air. Stow ob- as the former has no effedf upon quickfilver. An eafy - stained. and cheap method of obtaining this kind of air is by filling a phial, fitted with a glafs tube and ftopper, with common fait, and then pouring a fmall quantity of oil of yitriol upon it; which, by the affiftance of heat, will difengage the acid principle, or the marine acid air, from the fait. “ A phial (fays Dr Prieftley) prepared in this manner will fuffice, for common ex¬ periments, many weeks ; efpecially if fome more oil of vitriol be occafionally put to it. It only requires a little more heat at the laft than at the firft. Indeed, at firft, the heat of a perfon’s hand will often be fuf- ficient to make it throw out the vapour. In warm weather it will even keep fmoking many days without the application of any other heat. On this account it fhould be placed where there are no metallic uten- fils which it can corrode ; and it may eafily be per¬ ceived when the phial is throwing out this acid vapour, as it always appears in the open air in form of a light white cloud.’’ After the marine acid has yielded all the air that 171 can be expelled from it, it is extremely weak, fo that Its proper- it can but barely corrode iron. The gas itfelf is con- ties. fiderably heavier than common air, the fpecific gravity of the two being in the proportion of five to three ; a cubic inch weighing 0.654 grains. It is very fatal to animal life, but lefs fo than pure nitrous air; for flies and fpiders live longer in marine acid than in ni- troits air. In dipping a candle into a jar of this air the flame is extinguifhed ; but the moment btfore it goes out, and alfo w'hen it is afterwards firft lighted again, it burns with a green or light-blue flame, like that of common fait thrown into a fire. Its diminu¬ tion by the electric fpark is barely perceptible. Ice is diffolved by it as fait as if it touched a red-hot iron. It is partly abforbed by almoft every fubftance con¬ taining phlogifton, and the remaining part becomes inflammable. Oil of olives abforbs it very flowly, and oil of turpentine very'fail ; by which they both be¬ come almoft black, and the remainder of the air is in¬ flammable. Effential oil of mint abforbs marine air pretty fait, becoming brown, confiftent, and fo heavy N° S' l as to fink in water ; and its fmell is in great meafure Flyor Acid altered. Ethe'r abforbs it very faft, and has its colour ^ir> &c- altered by the impregnation, becoming firft turbid, v ' then yellow, and at laft brown. The air over the ether jyi is ftrongly inflammable. A fmall bit of phofphorus Changed fmoked and gave light in this acid air ; and the elaftic into iniiam- ftuid was but- little diminilhed in twelve hours. Onma e air* the admiflion of water, about four-fifths of the gas were abforbed, and the reft was inflammable. This change was alfo effedfted by a great number of other fubftances: fome of which, however, required a con- fiderable time to produce their effeft ; fuch as crufts of bread not burned, dry wood, dry fleflx, roafted pieces of beef, ivory, and even flints. SccChemistry, (Index.) § 4. Of Fluor Acid Air.—The difeovery of fluor acid air was made by Mr Scheele, who obtained it by diftilling the fpar called fluor with vitriolic acid. Dr Prieftley, who made feveral experiments upon the fub- jetft, was of opinion that this new' acid was only the Different vitriolic difguifed by its connection with the fluor. (!nm vuno- He even fuppofed that he had produced it by pouring 1C aci air<> vitriolic acid on other phofphoric fpars: both thefe opinions, however, he has now retraced, and believes the fluor acid to b.e one of a peculiar kind. Its moft remarkable property is the great attraction it has for filiceous earth, fo that it even corrodes and makes holes in the retorts in which it is diftilled. See Che¬ mistry, (Index.) - § 5. Of the Vegetable and another Acid Air.—By means of heat alone, the concentrated vegetable acid emits a permanently elaftic and aerial fluid. This has the properties of the acid of vinegar ; but, like it, is weaker than the reft of the mineral acid airs, though it agrees with them in its general characters. Water imbibes it as readily as any of the other acid airs; oil- olive readily abforbs it, and in confiderable quantity, lofing at the fame time its yellowifh colour, and be- 174 coming quite tranfparent.

The moft proper method ed from he-of obtaining this air is by pouring marine acid on he- par fulphu-par fulphuris, which extricates it in vail quantity. It is faid alfo to be fometimes produced naturally from putrefying matters. It is the chara&eriftic of all li¬ vers of fulphur, whether they be made with alkalis or earths. The fmell of the pure gas is intolerable ; and the vapour has a difagreeable effect on many metallic fubftances, particularly filver, lead, copper, &c. de- ftroying their colour, and rendering them quite black. It is fuddenly fatal to animal life, renders fyrup of violets green, and is inflammable, burning with a very light blue flame. It is decompofed by vitriolic and nitrous air, by dephlogiilicated air, and by the contact of atmofpherical air, in which cafe it depofites a fmall quantity of fulphur ; being indeed, as is fuppofed by Mr Bergman and Mr Kirwan, no other than fulphur kept in an arrial form. Its fpecific gravity, compared with that of atmofpherical air, is as 1106 to 1000. It combines readily with water, and gives the fmell to the fulphureous medicinal waters. Its great attra&ion for fome of the metals and their calces makes it the balls of fome Sympathetic Inks. See alfo Chemistry, (.Index.) Sect. XII. Of Jtmofpherical Air. ■ The two component parts of our atmofphere, viz. dephlogifticated and phlogifticated air, have been fo fully treated of under their refpe6tive fedlions, that little remains to be faid in this place, excepting to de- t-g termine the proportion in which they are ufually met Proportion with in the common air. The only regular fet of ex- of the two perjments which have been made on this fubjetff are •cfwhidi^8 thofe Mr Scheele. He conftru&ed an eudiometer, iscompofed. confifting of a glafs receiver, which could contain 34 ounces of water, and a glafs cup containing a mixture of one pound of iron-filings, and an equal weight of flowers of fulphur moiftened ; which cup Handing up¬ on a glafs fupporter, was inferted in the former re¬ ceiver, which, when this was in it, could contain 33 ounces of water. To the outfide of the glafs tube or receiver, was affixed a flip of paper, to the height of a third of the tube, containing 11 divifions, each corre- fponding to one ounce of water. This paper was var- i)idled over with oil varnilh, to prevent its being fpoil- ed by water. The whole then was placed in water, which gradually rofe as the air was diminiflied. This mixture would ferve four times before the power of di- miniftiing air was loft. He carefully compared the height of the air therein with the barometer and ther¬ mometer, both before and after the experiment; in eight hours the experiment was completed. With this inftrument he examined the goodnefs of the com¬ mon air in Stockholm every day for a whole year, and found the diminution never to exceed nor to fallftiort of -j-y; fo that upon a medium it may be eftimated at y9-.

The fmall variation in the quantity (hows, that the procef¬ fes in nature which deftroy this air, are nearly balanced by thofe which produce it; though it muft appear fur- prifing, that both thefe fluids, fo extremely different, Ihould be produced at all feafons of the year in a pro¬ portion nearly equal; nor is it lefs furprifing that two fluids of unequal fpecific gravity ftiould remain incor¬ porated together without any tendency to feparate, which it is certain they never do, either in the atmo¬ fphere itfelf, or when confined in veffels in any quanti¬ ty whatever.—A s phlogifticated air is fomewhat light¬ er than dephlogifticated, it might be fuppofed that the 179 former would occupy the higher regions of the atmo- Upper re- fphere in fuch a manner as to render them confider- ably more unwholefome than the lower parts ; but this faiubrious feems not to be the cafe : On the contrary, it appears than the by experiments with the eudiometer, that the upper lower. parts of the air contain a greater proportion of dephlo¬ gifticated air than thofe near the earth. See Eudio¬ meter. Sect. XIII. Of the artificial Production of Ain of different Kinds. § 1. Fixed Air, or Aerial Acid. The artificial me¬ thods of producing this are principally three, viz. by fermentation, by heat, and by acids. (1.) By fermentation. When vegetable or animal fubftances, efpecially the former, are fermented, they yield a great quantity of fixed air. In breweries, on the furface of the fermenting liquor, there is always a ftratum of fixed air reaching as high as the edge of the vats; fo that if thefe veffels are deep, and the ferment¬ ing liquor much below their edges, the above-mention¬ ed ftratum may be fome feet in thicknefs. The fame phenomenon is obfervable in the fermentation of wines in general; and it is owing to the produ&ion and ela- fticity of fixed air, that fermenting liquors, when put into clofe veffels, often burft them with great violence. The cafe is the fame whatever fubftance it is that un¬ dergoes the vinous fermentation, though the quantity of fixed air produced is not the fame in all fubftances, nor even in the fame fubftance at different times. From 42 cubic inches of beer Dr Hales obtained 639 cubic inches of air in 13 days. From a quantity of fugar A a undergoing i86 O O Y. Sea. xnr. OfArtificial undergoing the vinous fermentation, Mr Cavendifh ob- lefs mixed with any putrid or offenfive effluvium, than OfArtificiai tained fo much fixed air, that out of too parts of the former 57 appeared to have been volatilized and con¬ verted into fixed air. But though a vaft quantity of fixed air efcapes du¬ ring this procefs of fermentation, a very confiderable portion ftill remains united with the fermented liquor, and to this it owes all its brilknefs and agreeable pun¬ gent acidulous tafte ; for when the fixed air is totally evaporated, the liquor becomes entirely vapid and flat. Hence alfo we are furniflied with a method of reftoring the brifltnefs to thefe liquors after they have loft it in a whole animal,* or than the liver, &c. The propor-( tion of inflammable and of fixed air is alfo various, ac¬ cording to the various parts employed. (2.) By heat. In every combuftion, except that of fulphur or of metals, a quantity of fixed air is genera* ted. This mav be obferved bv fixing a lighted candle in an inverted receiver over a bafon of lime-water, for a precipitation of the lime will prefently enfue; and the fame precipitation (which is one of the charade- rift ics of fixed air) will always enfuc, whether a candle, a burning piece of wood,, or, in fhort, any other com- confequence of being expofed to the atmofphere, viz. buftible fubftance, except fiilphur or metals, be made by impregnating them again with fixed air, either na- ufe of.. i4- oz. meafure" of rwj Si: 5" J During this produftion or extrication of fixed from atmofpherical air, the latter is commonly fuppofed to be confiderably diminifhed, though Mr Lavoiiier and Mr Scheele have now rendered that opinion doubt¬ ful. If a piece of charcoal be burned by throwing- the focus of a lens upon it when contained, in a glafs- receiver inverted in water, after the apparatus is cool¬ ed, the water will have mounted a fmall way into the-' receiver. The diminution, however, is limited, and depends on feveral circumftances. Dr Hales has ob¬ ferved, that, in equal receivers, the air fuffers a greater diminution by burning large candles than fmall ones ; and likewife that, when equal candles are made ufe of,, the diminution is greater in fmall than in large recei¬ vers. The caufe of this phenomenon probably is, that the air contained in the receiver cannot all come into contadt with the flame of the candle j whence, as fooa as the air which is neareft the flame becomes conta¬ minated, the candle is extinguiflied. Thus the author of a Concife Treatife on the Various Kinds of Perma¬ nently Elaftic Fluids, has diminifhed the air of an in¬ verted receiver one fixth part, by moving the candle whilft it burned through the different parts of the yef- fel, fo that the flame was brought into contact with a greater quantity of the confined air than if it had re¬ mained in one fituation till it became extindt. Dr Mayow obferved, that by the burning of a candle the air was diminifhed of one thirtieth only ; Dr Hales found it to be diminifhed of one twenty fixth part; and Dr Prieftley found it to be diminifhed of one fifteenth turally or artificially produced. Dr Prieftley has made feveral experiments in order to determine the quantity of fixed air contained in fe¬ veral forts of wine. His method was to take a glafs phial (fitted with a ground ftopple and tube),, capable of containing i|- ounce-meafure. This he filled with wine, plunging it into a proper vefl'el of water. The whole was then put over the fire, and the water,, into- which the phial was plunged, fuffered to boil. The end of the tube being placed under the mouth of an inverted receiver filled with quickfilver, the heat expel¬ led the fixed air from the wine, which entering into the receiver, afcended in bubbles through the quick- Jilver to the top, pufhing out part of the metal and ta¬ king its place. The refult of his experiments, was as follows : Madeira ( Port of fix years old Pn . -/-j- j of a Hock of five years Barrelled claret Tokay of 16 years ^ Champagne oftwoyears g 2 oz. meafures. .Bottledcydevof 12years [ 8 3^- ditto. During the acetous fermentation alfo, liquors emit a vapour, great part of which is fixed air, though the nature of its other component parts has not. yet been thoroughly afcertained. Fixed air is likewife produced, though in no great quantity, by putrefaftion. Iti this cafe, however, a great part of the elaftic fluid confifts of inflammable and phlogifticated air, and the fixed air itfelf feems to or fixteenth. Mr Cavendifh obferved, that air fuf- be intimately connedted with a putrid offenfive effluvi¬ um. It feemed to Dr Priellley to “ depend in fame meaftire upon- the time and other circumftances in the diffolution of animal or vegetable fubftances, whether they yield the proper putrid effluvium, or fixed or in¬ flammable air.” The elaftic fluid produced by putrifying vegetables, when kept in a moderate degree of heat, is almoft all fixed air; while that from animal fubftances contains feveral times more inflammable than fixed air. Vege- fered a diminution of one-tenth of the whole quantity, by, palling through an iron-tube filled with red-hot. powder of charcoal. A. candle, or any other Combuf- tible body, will ceafe to burn by itfelf, and confequently to contaminate a quantity of confined air much fooner than when it is, in fame manner, forced to burn by the external application of heat. “ The focus of a burn¬ ing mirror,” fays Dr Prieftley, “ thrown for a fuffi- cient time either upon, brimftone or wood, after it has ceafed to burn of its own, accord, and has become table fubftances yield almoft all the permanently elaftic charcoal, will have a much greater effect of the fame fluid in a few days, but animal bodies continue to emit kind, diminifhing the air to its utmoft extent, and it for feveral weeks. When the elaftie fluid yielded making it thoroughly noxious.” The combuftion of by animal fubftances is abforbed by water, and that the phofphorus of urine diminiflies air in a great de- water boiled, the fixed air may then be obtained with- gree. Mr Lavoifier has obferved, that by the com- out any mixture of the putrid effluvium. It is alfo to bullion of phofphorus, air maybe diminilhed of about, be obferved, that the quantity of elaftic fluid produ- one-fifth or one-fixth. This accurate philofopher has clble from animal fubftances is various according to alfo obferved, that the acid of phofphorus thus formed, the nature of the parts of the animal employed. Thus acquires the weight loft by the diminilhed air; finding the mufcular parts will yield leis elaftie fluid, and alfo that about three inches of air were abforbed by every 4 ’ one Se&.XHT. AERO OfArtifidal one grain o? phofphorus, when the experiment was -Airs- | tried with a receiver inverted in water, upon the fur*- v face of which a fmall quantity of oil had been intro¬ duced ; but when the receiver was inverted in quick*- filver, the abforption was conftantly between two one- fourth and two three-fourth inches for each grain* Mr Cavallo mentions his having often repeated the expe¬ riment of burning phofphorus in a glafs tube inverted in water, by applying the clofed part of the tube, wherein the phofphorus was contained, to a pretty ftrong fire, when he always obferved that the utmoft diminution of the inclofed air effedled by this means was full one-fifth. Dr Hales remarked, that after the extinction of candles in a receiver, the air continued to diminifh for feveral days after. This may be owing to the gradual abforption of part of it by the water; it having been remarked by Dr Prieftley, “ that this diminution of air by burning is not always immediately apparent, till the air has palfed feveral times through water; and that when the experiment was made with veffels Handing in quickfilvqj- inftead of water, the diminution was generally inconfiderable till the air had palfed through water.” In thefe experiments of burning combuftible bodies in a quantity of air, and meafuring the diminution, we jhould always remark two caufes of miftake, viz. the abforption of air by the coaly refiduum of the burned matter, which fometimes is very confiderable, or by the fluid in which the receiver is inverted, and the produc¬ tion of elaflic fluid from the burning fubftances ; thus gunpowder generates a great quantity of elaftic "fluid when inflamed, &c» Even the eleftric fpark feparat-es fixed air from com¬ mon atmolpherical air; for when a number of thefe fparks are taken in a fmall quantity of common air over lime-water, a diminution will take place, the lime will be precipitated, and if we put a blue vegetable juice inllead of the lime-water, it will be turned red by the acidity of the fixed air depofited upon it. Dr Prieftley having cemented a wire into one end of a glafs tube, the diameter of which was about one-tenth of an inch, and shaving fixed a brafs ball to that extremity of the wire which was out of the tube, filled the lower part of it with the juice of tumfole or archil, fo that a quantity of common air was contained in the tube be¬ tween the extremity of the wire and the furface of the liquor. Then taking eleftric fparks between the faid wire and liquor for about one minute, the upper part of the liquor began to look red, and in about two mi¬ nutes it was manifeftly fo. The air, at the fame time, was diminifhed in proportion as the liquor became red; but when the diminution arrived to be one-fifth of the ■quantity of the air contained, then a longer eleftriza- tion produced no fenfible effedf. “ To determine,” fays the Doftor, whether the caufe of the change of colour was in the air or in the eleftric matter, I ex¬ panded the air which had been diminifhed in the tube by means-of an air-pump, till it expelled all the liquor, and admitted frefh blue liquor in its place ; but after that, electricity produced no fenfible effedi, cither on the air or on the liquor; fo that it was evident that the eledtric matter had decompofed the air, and had made it depofite fomcthing that was of an acid nature.” The calcination of metals, as already obferved, phlo- gifticates, and confequently diminilhes comir.on air ; LOGY. 187 hut does not produce any fixed air, fince the lime-water, OfArtificial over which the calcination is made, does not become , , turbid ; and when metallic calxes are expofed to a fuf- v ficient ftrong heat, they in general yield fome fixed air: fo that it feems that the fixed air which is formed in the adt of the calcination of metals is abforbed by the calx. Some fixed air may be obtained from red lead, by no greater degree of heat than that of the flame of a candle applied to the phial that contains it. The calcareous earths, which, when a died on by obtained acids, yield a vaft quantity of fixed air, produce a very from earths fmall quantity of it when expofed to a ftrong heat by themfelves, in a proper veffel, even when expoled to the ° ei ' focus of a lenS. Dr Prieftley, in his experiments re¬ lating to the production of dephlofticated air from va¬ rious fubftances, when moiftened with nitrous acid, and afterwards expofed to a fufficieht degree of heat, gene-* rally found that fome fixed air was produced together with the dephjogifticated air ; but often obtained fixed air only, without any dephlogifticated air being mixed with it, or fixed and nitrous air together* From half an ounce of ruft of iron, moiftened with fpirit of nitre, and dried, he Obtained about a quart of elaftic fluid, about one-third of which was fixed and the reft nitrous air. From alhes of pit-coal, treated in the fame manner, he obtained nearly the like refult. But'in thofe experi¬ ments, theDoftor moilly ufed a gun-barrel, into which he introduCed the fubftances to be tried; fo that it is very probable, as he juftly obfervcs, that the iron might have contributed to the formation of the fixed air. In faft, when he tried fubftances of the fame fort, firft in a gun* barrel and then in glafsveffels, he obtained much more fixed air in the former than in the latter cafe. One of thofe experiments he made with tobacco pipe-clay, which, after'being moiftened with fpirit of nitre, was when dry expofed to the fire in a gun-barrel, and yield¬ ed fome elaftic fluid, which appeared to be wholly fix¬ ed air ; but repeating the experiment in a glafs-phial with a ground ftopple, and taking the produced da- ftie fluid at eight different times, found that on the begimnng fome fixed air was produced, but afterwards the produce was dephlogifticated dr. He,made a fimilar experiment with flints carefully calcined in clofe veffels, and obtained a fimilar refult. ^ Moft minerals contain fixed air, which may be ex-jrom dige4 traded to a certain degree by means of heat. Mrirent miue- Krenger, diftilling a grecnifh fufible fpar, which was^als. luminous in the dark, obtained from it fome perma¬ nently elaftic fluid, which, like fixed air, cryftallized a folution of fixed alkali. Mr Fontana, in his analyfis of the malachite, finds that that mineral contains a vaft quantity of fixed air, as pure as that which is extract¬ ed from chalk by means of vitriolic acid. From almoft every metallic ere and earthy mineral fome fixed air may be obtained, as well as from chalk, lime-ftone, marble, marine (hells, fixed and volatile al¬ kali, and from magnefia alba, by means of a violent fire, ot of acids. In Mr Boyle’s, Dr Boerhaave’s, and Dr Hales’s w'orks, and in other books, the quantities of elaftic fluid generated in various proceffes, and by divers fob-* ftances, are mentioned with diftin&ion; but as thofe writers were not acquainted with the charafteriftic pro-* perties of fixed air, we do not know whether the elaftic fluid mentioned by them was pure fixed air or not. A a 3 From i88 A E R Q OfArtlficial From animal fubftanees, mixed with fpirit of nitre, , Airs- , and fometimes heated a little, in order to facilitate the ~ v produftion of elaftic fluid. Dr Prieftley obtained, in general, fixed air ; but whereas the fixed air produced by a fimilar procefs with vegetable fubftances is moftly mixed with nitrous air, this is mixed with an elaftic fluid, which is feldcm nitrous in a very flight degree, but is often phlogifticated air, viz. in fuch a ftate as f xtinguifhes a candle, does not diminifli- common air, nor is itfelf diminifhed by nitrous air. Towards the end of the procefs, the Doftor remarks, “ that when, by means of a ftrong heat, the produce of air is very rapid, and the air full of clouds, it is, like air, produ¬ ced from vegetable fubftances in the fame circumitan- ces, flightly inflammable, burning with a lambent, 181 greenifli, or bluifli flame.” Abundant- (3.) By acids. Calcareous fubftances in general pro- ly produced (]uce abundance of fixed air when acted upon by any reous fub-a"ac^’ onty the ftrongeft acids will expel from them fiances. more fixed air than the weakeft; and it happens to be peculiarly advantageous for thofe who want to produce a great quantity of fixed-air, that the vitriolic acid is both the cheapeft and ftrongeft acid, and, upon the whole, the fitteft for this purpofe. The phenomena attending the production of fixed air from calcareous fubftances, &c.. are themfelves very remarkable, and. furnifh the fubjeft of much fpeculation in philofophy.. —The principal fads are the following. 1. When calcareous earths, alkalis, and magnefia, in their ufual ftate, are mixed with acids, they caufe an effervefcence; and confequently the produdtion of a permanently ela¬ ftic fluid, namely, fixed air. 2. Thefe fubftances re¬ tain the fixed air very obftinately; fo that a ftrong fire is neceflary to expel it from magnefia, and the ttrongeft is not fufficient to expel it entirely from fixed alkalis, and efpecially from calcareous earths (a). When thefe fubftances are treated with acids, they yield the fixed air, becaufe they have a ftronger attradion to thofe acids than to the fixed air. 3. The calcareous earths which are infoluble in water, when deprived of the fixed air become foluble in it. Thus lime-ftone is not foluble in water, but lime (viz. lime-ftone deprived of its fixed air) is foluble in water. And if thofe fub- iftances, deprived of their fixed air, are put in a fitua- tion proper to recover their loft fixed air, they lofe the property of being foluble in water. Thus, when lime-water is expofed to fixed air, the lime abforbs the fixed air; and, lofing at the fame time its property of being foluble in water, is precipitated from it in the ftate it was before calcination, viz. of a calcareous earth infoluble in water, and capable of effervefeing with acids. 4. Alkalis, both fixed and volatile, when deprived of their fixed air, become more cauftic, and more powerful folvents, incapable of cryftallization, and of effervefeing with acids. But if to thofe alkalis, and alfo earths rendered more cauftic, their fixed air be reftored, they acquire at once all the properties they had before they were deprived of the fixed air, viz. they become more mild, effervefee with acids, re¬ cover their weight, &c. LOGY. Sea.XTin. Thofe properties of calcareous earths and alkalis OfArtificial were afeertained by the learned Dr Black, who per- A‘rs' formed: a variety of decifive and well-contrived experi¬ ments, upon which he formed a juft theory, viz. that the cauftieity, ftiarpnefs, folubility, &c. of thofe fub¬ ftances, wras owing to the fixed air being expelled from them; and that when they were combined with.a pro¬ per quantity of fixed air, they were mild, &c. The Docftor gives the epithet of mild to thofe fubftances: when they are combined with air, and of cauftic when- deprived of it; as.cauftic calcareous earth, cauftic fixed- alkali, &c. Among the other experiments, he connec¬ ted two phials by means of a bent tube; in one of which he put fome cauftic fpirit of faf ammoniac; and in the other fome mild, alkali, or mild calcareous-: earth; then pouring, through a hole made in the. fide of the latter phial, fome acid upon the mild alkali, fo as to produce fome fixed air, which, palling through the tube into the other phial, combined with the fpirit of fal ammo¬ niac, and rendered it mild. Eajy methods of obtaining Fixable Air for occaftonal Experiments, &c. ( .) By Fermentation. Mix together equal parts oft brown fugar and good yeft of beer, to which add about twice the bulk of water. This mixture being put in¬ to a phial, to which a bent tube with a cork may be adapted, will yield a confiderable quantity of fixed air,, which may be received into a phial filled with quickfil- ver or water, as in the following procefs. (2.) By Acids. Let a glafs tube, open at both ends, be bent, by means of a blow-pipe and the flame of a candle, nearly into the ftiape of an S, as it is repre- fented by AB, and fix a cork D to one of its extre-plate mities, fo as to fit the neck of a common phial, that 1* may hold about four or five ounce meafures. The hole through the cork may be made with an iron wire red- hot, and the tube may be faftened in it with a bit of foft wax, fo as not to let any air go through. Fill a fimilar phial, or any glafs receiver K, with water, and Cavallo m invert it after the manner Ihown above, in.abafin about half filled with water Now put fome chalk or marble, grofsly powdered, into the bottle E, fo as to fill about a fourth or fifth part of it, and upon it pour fome water, juft enough to cover the chalk ; then add fome oil of vitriol to it, which needs not be more than about the fourth or fifth part of the water. Imme¬ diately after, apply the cork D, with the tube AB, to the bottle, and putting it in the fituation FG, let the extremity B of the tube pafs through the water of the bafin into the neck of the bottle K, which now muft be kept up with the hand, or other convenient fupport, as it cannot reft upon the bottom of the ba¬ fin. The mixture of chalk, &c. in the bottle FG, will immediately begin to effervefee, ftiowing a froth¬ ing, and an inteftine motion accompanied with heat, that may be felt by applying the hand to the outfide of the fluid. The elaftic fluid called fixed air is co- pioufly emitted from this mixture, and pafling through the bent tube, will go into the bottle K, as appears by the bubbles which come out of the tube, and, paf- fing (a) Chalk, lime-ftone, &c. after being kept in a very ftrong fire for many hours, if they are put into acids, yield a confiderable quantity of fixed air; which ftiows that the pureft quick-lime contains fome fixed air. | Sea. xm.

In proportion as the elaftic fluid fills * the bottle K, the water gradually defcends, and at laft is quite expelled from it; the bottle K then is filled with fixed air, and being corked under water, may be removed from the bafin, and kept for ufe. Another bottle may then be filled with water, and may be in¬ verted over the extremity of thcbent tube in the place of K, which other bottle may be filled in a fimilar man¬ ner, and fo on till the mixture in FG has finifhed to yield any fixed air. If one of thefe bottles filled with fixed air be un¬ corked, and, holding it with the mouth upwards, a lighted wax taper, bent like L, or a fmall piece of it affixed to the extremity of a wire, be immediately let down in it, the flame will be inftantly extinguiffied. The fame thing will happen if a lighted piece of wood is let down in it. Take a clean bowl, and putting the mouth of a bot¬ tle, filled with Iked, air, in it, uncork it, and keep it in that fituation for about a minute. The fixed air be¬ ing fpecifically heavier than common air, will come out of the bottle, and will remain at the bottom of the bowl, whilft common air enters into the bottle; which 1, bottle may now be removed ; and, in order to ffiow the real exiftence of the fixed, air, which will immediately I Ca-vallo q» (how its being heavier than common air,, put, a lighted /**r‘ wax-taper into the bowl, pretty near its bottom, which taper will be extinguiffied immediately. The air in this experiment muft be agitated as little as it is pof- fible. That the flame of the wax taper was really ex¬ tinguiffied by the fixed air, may be eafily proved in the following manner:—Blow once or twice into the bowl, by which means the fixed air will be expelled from it; and then, on letting down a lighted wax-taper in it as before, it will be found that it is no longer extinguiffi¬ ed, but will burn very well, the bowl being now filled with common air. This experiment never fails of fur- prifing the fpeffators, as it clearly exhibits two remark- . able properties of a fluid, which they can neither fee nor diftinguiffi by the feeling. When the bottle K is about half filled with fixed air, put a mark with a bit of foft wax on the outlide of it, juft coinciding with the level of the water in it, and immediately after ffiake the bottlebut taking care that its mouth be not lifted above the furface of the water in the bafin. After having ffiaked it for about a minute, on intermitting the agitation, it will be found that the water is above the mark; which {hows that feme of the fixed air has been abforbed by it. Let this abforption be carried on as far as pof- fible, by agitating the bottle repeatedly, and allowing time to let more fixed air be produced and enter into the bottle in proportion as the water abforbs it. Then appply the hand, or a finger, to the mouth of the bottle whilft under waterbring the bottle out, and turn it with the mouth upwards.. The water then will be found to have acquired a pleafant acidulous tafte. The water thus impregnated with fixed air changes the blue infufion of feme vegetable fubftances into red ; fo that if a weak folution of heliotrope is mixed with it, or indeed if it is fimply expofed to fixed air, the liquor acquires a reddiffi appearance. It alfo corrodes iron, and fome other metals, much more eafily than common water.. But the greateft and moft. ufeful property of LOG Y. 189 this acidulated water, or water impregnated with fixed CfArtiiiciui air, is its being a powerful antifeptic. As the moft, A!f%‘ , ufed mineral waters are medicinal principally on account of their being impregnated with fixed air, befides which they generally contain fome fmall portion of metal or fait diffolved ; they may be imitated by impregnating- water wdth fixed airv and then adding that quantity of fait or of metal, that by analyfis the. original mineral waters are found to contain* 183 It is for its great property of hindering putrefac-Ufrfui pro- tion, that fixed air by itfelf, or incorporated with va-.Pert:es.°^ rious-fluids, efpecially with water, and that vegetables, xe air* fugar, and other fubftances wffiich abound with fixed air, are very powerful remedies in putrid difeafes. Sir John Pringle fuppofes, with great probability, that the frequent ufe of fugar and freffi vegetables, which at this time make up a confiderable part of the diet.of the European nations, prevents thofe putrid difeafea and plagues which formerly were rather frequent.—- Dr Macbride, ffiow'ing experimentally that fixed air is difeharged by fuch fubftances as form our common food, aferibes the prefervation of the body from putre¬ faction.in great meafure to the fixed air, which in the ordinary procefs of digeftion is difengaged from the a* liment, and incorporates with the fluids of the body. From the fame property it may be alfo ufefully ap¬ plied to feveral ceconomical purpofes. Mr Henry found, that fixed air can preferve fruit for a confider¬ able time. He tried a bunch of Italian grapes, which being fufpended in the middle part of Dr Nooth’s ap¬ paratus, and being fupplied with plentiful ftreams of fixed air every day, was preferyed without any figns of decay for about one month longer than a fimilar bunch fufpended in a decanter containing common air. Strawberries and cherries he alfo found to be prefer- ved without decay fome days longer in fixed than - in common air. Indeed, fixed air preferves not only fruit, but refifts putrefaction in generaL Dr Mao bride, in his elegant Eflays on Medical and Philoio- phical SubjeCts, has publiffied variousexperiments which demonftrate this property of fixed air. He found, .that not only goad meat was preferved incorrupt for a con¬ fiderable time, when expofed to fixed air;,but that the putrefaction of fubftances aCtually putrid was im¬ peded by this means, and even that thofe fubftances were reitored from the putrefeent to a found ftate. That putrefaCtion was checked by fermentation, was Rtfifis .-u. difeovered by Sir John Pringle; and Dr Macbrideu-efuctio... obferved, that this effeCt was owing to the- fixed air produced in the aCt of fermentation. But it muft be obferved, that when the found, or even putrid fob-! ftances, expofe a very great forface to the .fixed air, as is the cafe with milk, bile, and other fluids impregna¬ ted with fixed air, and alfo with fmall bits of meat, then they are preferved for a confiderable time : but large pieces of folid animal fubftances, as. for inftance roundiffi pieces of fleffi of about half a pound weight, do not feem to remain incorrupt much longer in. fixed than in'eommon air; at leaft the difference is inconfi- derable. Sir William Lee, baronet, in two of his h •- ters to Dr Prieftley, informs him of his having found, that fleffi-meat, even in the hot feafon, could be pre¬ ferved wholefome for feveral days, by only waffiing it two or three times a-day in water impregnated with fixed. 190 AERO' OfArtific'ai fixed air. tl We have been enabled,” lays he, “ to , Airs' , preferve meat as perfectly fweet and good to the ex- v ' tent of ten days, as at the firft killing ; and there feems no doubt it might be preferved much longer.” He has even recovered fome meat that had begun to change. This ufeful difcovery. Sir William juftly ob- ferves, may be very beneficial to the public, efpe- cially to butchers. “ Particularly a butcher,” fays he, “ who deals pretty largely, alfures me he found the greateft fuccefs from it, and only objects that the veal was a little difcoloured, though kept perfe&ly fweet.” Fixed air, as it combines with water, fo it may be combined with other liquors. Beer, wine, and other fermented liquors, may be impregnated with fijsed air, and by this means their lharpnefs may be reftored, when they are become vapid, or, as it is commonly faid, dead. The acidulous tafte communicated by the im¬ pregnation of fixed air, cannot be difcovered in beer, ■wanes, and, in fhort, in fuch liquors which have much tafte of their own. Milk acquires an acidulous tafte by being impregnated with fixed air, and is thereby preferved incorrupt for fome days ; which affords a very eafy expedient of preferving milk in thofe places where it cannot be had new very often. 185 Production £ 2. To produce Inflammable Air.—The procefs of inflam- for ma}l;ng this fort of gas is the fame as that for ma¬ ma c air. gxe(j ajr . one 0f the materials only muft be dif¬ ferent, viz. iron-filings, or grofsly powdered zinc, mull be ufed inllead of chalk ; to which filings fome oil of vitriol and water muft be added, in the fame propor¬ tion as in the fixed air, or rather a little mofe of oil of vitriol. N.B. Inftead of the filings of iron, fmall nails, or fmall bits of iron-wire, anfwer equally well. The inflammable elaftic fluid produced by this mix* ture has a difpleafing fmell, even when mixed with a very large quantity of common air ; fo that if any confiderable quantity of it comes out of the bottle, before the cork with the bent tube be applied to it, &c. its fmell may be perceived all over the room in which the experiment is made, but this fmell is not particu¬ larly offenfive. When a bottle has been filled with this elaftic fluid, Hop the mouth of it with your thumb, or any Hopper, and taking it out of the bafin, bring it near the flame of a candle ; and when the mouth of the bottle is very near it, remove the ftopper, and the elaftic fluid con¬ tained in the bottle will be immediately inflamed; and if the capacity of the bottle is nearly equal to four ■Ounce-meafures, it will continue burning quietly for about .half a minute, the flame . gradually defeending lower and lower, as far as about the middle of the bot¬ tle, in proportion as the inflammable gas is confumed. In this experiment we fee, that inflammable air fol¬ lows the general rule of all other combuftible fub- ftances, namely, that of burning only when in contact with common air: thus the flame of this gas, whilft burning, is obfervable only on that furface of ft which ^ is contiguous to the common air ; fo that if the bottle Pheno ke clofed, the flame is put out immediately, becaufe mena. the air is intercepted from it. But if the inflammable air were put in fuch a fituation as to expofe a very great furface to the common air, it is plain, that by LOOT. Sea. XBt, this means its combuftion would be accelerated, fo as OfArtifidal J to let it burn inftantly, and go off with an explofion, , Airs~ . caufed by the fudden rarefaftion of the air. In fa£t, " v ' this effect may be eafily obferved in the following man¬ ner: When the bottle is to be inverted into the bafin, in order to let it be filled with the inflammable gas, inftead of filling it entirely with water, let half of it remain filled with common air; then invert it, and let the other half, which is now filled with water, be filled with inflammable air after the ufual manner; and when the bottle is full, remove it in the manner {flown above, and approach it to the flame of the candle, by which means the inflammable air takes fire ; but now it ex¬ plodes all at once with a large flame and a confider¬ able report, fometimes breaking the bottle in which it is contained. In this cafe, the bottle being filled with equal parts of inflammable and common air, thefe two elaftic fluids were mixed together, fo that almoft every particle of the one touched every particle of the other, and hence the fudden combuftion was occafioned. The force of this explofion is fo very confiderable, that fome piftols have been contrived, which are charged with a mixture of air and inflammable gas, and being fired by means of an ele&ric fpark, are capable to drive a leaden bullet with great violence. Sometimes thofe j piftols are made of glafs (but in this cafe they are not charged with a bullet), and it is very diverting to (how that piftols are charged and explode by the combuftion of an invifible fubftance-. When a {lender pipe is tied to the neck of a blad¬ der, and the bladder is filled with inflammable air, after the manner deferibed in the preceding experi¬ ment (viz. when the bladder was required to be filled with fixed air), two very pleafing experiments may be performed with it. Firft, the inflammable gas may be inflamed by applying the flame of the candle to the extremity of the pipe ; and fqueezing at the fame time •the bladder, a ftream of fire will be formed in the air, which will laft as long as the bladder contains any in¬ flammable air; for this gas coming out of the pipe with violence, will continue inflamed for a confiderable way in the air. Secondly, the extremity of the pipe may be dipped into a folution of foap, then removing it from the folution, and fqueezing the bladder very gently, a ball of foap-water may be formed, including inflammable ait: which ball, on account of the inflam¬ mable gas being much lighter than common air, as foon as it is detached. from the pipe will afeend upwards, and will break by daftiing againft the ceiling, contrary to thofe commonly made by children, which in ftill air go downwards.—Whilft the ball is afeending, if the flame of the candle be approached to it, the film of foap-water will be inftantly broke, and the inflam¬ mable air will take fire ; thus a flame may be fhown to be feemingly produced from a foap-ball. ^ By taking electric fparks in any kind of oil, fpirit Inflamma- df wine, ether, or fpirit of fal ammoniac, Dr Piieft-ble air ob- ley obtained inflammable air. The oil, or other li- tamed from quor, was confined in a glafs tube by quickfilver, and a wire was cemented in the upper part of the tube, through which the fparks being fent, went to the quickfilver through the oil; but after that a few fparks had been taken, a quantity of inflammable air was generated, See. Left the produttion of inflammable air ftiould be attributed to the cement which faftened the I Isea. Xlir. A K R o 2i ©fArtificial the wire, the Doctor repeated the experiment with Al^ ether in a glafs fyphon ; but the inflammable air was i generated as before. This elattic fluid does not lofe its inflammability by being palled feveral times from one velfel into another through water. Alkaline air, by taking eleftric explofions in it, is changed into inflammable air. By means of acids, inflammable air is obtained in greater abundance, and more readily. Iron, zinc, or tin, yield plenty of inflammable air when a&ed on by diluted vitriolic or marine acids. If iron is put into llrong vitriolic acid, the quan tity of elaltic fluid that is produced is very little, ex¬ cept heat be applied to the phial, for then the pro¬ duction of eiaftic fluid is more copious but this ela- itic fluid is vitriolic acid air, mixed with a fmall por¬ tion of inflammable air, the proportional quantity of it being lefs when the acid is more concentrated. Zinc, treated after the fame manner, produces the like effects, except that it gives more elailic fluid, without the application of heat, than iron does ; and the greats eft part of the produced eiaftic fluid is inflammable. In order to obtain the greateft quantity of inflam¬ mable air from iron or zinc, the vitriolic acid muft be diluted with much water, as about one part of ftrong oil of vitriol to five or fix parts of water. Dr Prieft- ley found, that 11 grains of iron yielded ounce- meafures of inflammable air. According to Mr Ca- vendifli, one ounce of zinc, diffolved either in the vi¬ triolic or marine acid, yields a quantity of inflammable air equal to the bulk of 356 ounces of water one ounce of iron, diffolved by means of vitriolic acid, yields a quantity of inflammable air equal to the bulk of 412 ounces of water ; and one ounce of tin yields half as much inflammable air as iron does. The folutions of iron, tin, copper, lead, and zinc, in the marine acid, produce marine acid air, and in¬ flammable air, but in various quantities. The propor¬ tion of the former to the latter is as. one to eight in iron, as one to fix in tin, as three to one in copper and lead,, and as one to ten in zinc. Regulus of anti¬ mony, diffolved in marine acid, with the application of heat, yields a fmall quantity of eiaftic fluid,, which is weakly inflammable. Dr Prieftley obtained inflammable air, not only by diffolving various fubftances in marine acid, but alfo by expofing divers bodies, to marine acid air, , which is probably the pureft part, of the marine acid. Having admitted iron-filings to this acid air, they were diffol¬ ved by it pretty fait ; half of the elaftic fluid difap- peared, and the reft was rendered unabforbable by wa¬ ter, and inflammable. The fame effe6t was produced by almoft every fubftance which contains plilogifton, as by fpirit of wine, oil of olives, fpirit of turpentine, charcoal, phofphorus, bees-wax, fulphur, dry cork¬ wood, pieces of oak, ivory, pieces of roafted beef, and even fome pieces of a whitiftt kind of flint. A greater or fmaller portion of the acid air was ab- forbed, and the reft fometimes was all inflammable, and often was partly acid air, which was foon abforbed on the admifiion of water, and partly inflammable. In fliort, it feems as if this acid air, having a great affinity with phlogifton, feparates it from all thofe fub¬ ftances which contain it even in fmall quantity, and from that combination becomes inflammable,- LOGY. 191 By means of nitrous acid, inflammable air may be OfAnificial obtained from various fubftances containing phlogifton ;, Airs- , but it is always mixed with nitrous air, and fometimes v alfo with fixed and common or phlogifticated air. If two parts of fpirit of wine, mixed with one part of nitrous acid, are put into a phial with a ground-ftopple and tube, and the flame of a candle be applied to it, fo as to heat it gradually, the inflammable air will be pro¬ duced very readily ; the inflammability of which is, however, not very permanent, for by a little waffiing in water it may be annihilated. In the folution of moft fubftances in nitrous acid, it generally happens, that the eiaftic fluid, which is obtained towards the latter end of the procefs, poffeffes the property of be¬ ing inflammable : thus iron, diffolved in nitrous acid, yields nitrous air; but when the nitrous air ceafes to be produced, if the heat of a candle be applied to the folution, more eiaftic fluid will be produced which is inflammable. “ The nitrous acid (fays Dr Ingen- houfz) when mixed with iron-filings in a very diluted ftate, gives, by the affiftance of a moderate degree of heat, a mixture of different airs, partly fixed, partly common air, and partly phlogifticated air. See further the article Aerostation. § 3. To produce Nitrous Air.—This permanently eiaftic fluid is never found naturally, like fixed or in¬ flammable air, but is entirely artificial. 188 Either filver, copper, brafs, iron, mercury, bifniuth, Nitrous air or nickel, when mixed with nitrous acid, yield nitrous ^ air in great quantities. Some of them, efpecially mer¬ cury, require the aid of heat in order to produce the eiaftic fluid ; the flame of a eandle applied to the phial is fufficient: but others, efpecially copper and iron, da not want the application of any heat. Gold, pla- tina, and the regulus of antimony, when put in aqua regia, yield nitrous air pretty readily. Among the metals, lead yields nitrous air in the fmalleft quantity. “ I poured (fays Dr Prieftley) fmoking fpirit of nitre into a phial with a ground-ftopple and •tube, contain¬ ing 1 r ounce-meafure filled with fmall leaden ihot, fo as to leave no common air at all, either in the phial or in the tube; and I placed it. fo as to receive the air that might come from it in water. After waiting an hour, in which little or no air waS p^^ produced, I applied the flame of a candle,. though fuijftanccs not' very near, to it: and in thefe circumftances I got produced, about an ounce-meafure of air : but upon fome water ruihing into the phial while the candle was withdrawn, air was produced very plentifully. I collefted in all about a quarter of a pint; and might probably have got much more, but that the fait formed by the folu¬ tion of the lead had fo nearly clofed up the tube, that I thought: proper to difeontinue the procefs. The air, both of the firft and of the laft produce, was of the fame quantity-; and fo far nitrous, that two meafures of common air, and one of this, occupied the fpace of two meafures only ; excepting that the very firft and very laft produce, mixed with common air, took up a little more room than that which I got in the middle of the procefs. When the air was produced very fail, it was exceedingly turbid, as if it had been filled with a white powder.” Among the femi-metals, zinc gives the weakeft ni¬ trous air, when diffolved in nitrous acid. The eiaftic fluid AERO ^ Maid produced from it is mo illy phlogifticated air. From four penny weights and 17 grains of zinc, diflbl- ved in fpirit of nitre diluted with an equal quantity of water. Dr Prieftley obtained about 1 2 ounce-meafures of very weak nitrous air. It occalioned a very flight effervefcence when mixed with common air. The Dodtor obtained nitrous air even from fome flowers of zinc. “ Having (fays he) mixed a quantity of blue fpirit of nitre with flowers of zinc, which were • of a dull colour, and appeared from feveral experiments to contain a portion of phlogi'fton, it yielded, with the heat of a candle applied to the-phial which contained it, ftrong nitrous air ; -when the common fpirit of nitre, applied in the fame manner, gave only phlogifticated air ; the phlogifton of which came probably from the calx itfelf, though a fmall portion of it might have been in the nitrous acid, which I believe is never entirely free from it.” The quantity of nitrous air that may be obtained from various metals, is difficult to be afcertained, on account of the diverfity occafioned by the ftrength of the acid, the various nature of the metallic fubftance, and the .method of .performing the experiments. The following is a table of the produces of nitrous air from various metals, extracted from Dr Prieftley’s firft vo¬ lume of Experiments and Obfervations; but which, as, the author himfelf intimates, is far from being very accurate. ,dwt. grs. 6 o of 151 ver yielded 174-ounce-meafures. 5 19 of qtiickfilver, 44. 1 24- of copper, 144- 2 o of brafs, 21 o 20 of iron, 1 5 of bifmuth, 6 o 12 'of nickel, 4 The various ftrength of the nitrous acid produces great diverfity in the production of nitrous air. Thus, if copper is diffolved in ftrong nitrous acid, it will not produce the leaft quantity of nitrous air; but when dif¬ folved in diluted nitrous acid, it produces a great quan- tity;of that elaftic fluid. The ftrong and pale-coloured nitrous acid fhould he diluted with at leaft two or three parts of water to one of the acid, for the eafy pro- duftion of nitrous air from copper and mercury. The brilknefs of the effervefcence, and the produc¬ tion of nitrous air, are promoted by heat, and alfo by letting the metallic fubftance prefent a great quantity of furface to the acids. For the generality of experiments, no other degree of heat is required than that produced by the effer¬ vefcence itfelf, except mercury be ufed, which requires the application of fome heat. When the metal exhi¬ bits a very great furface to the acid, as is the cafe when filings are ufed, the effervefcence and production of nitrous air are often much quicker than can be con¬ veniently managed. Copper or brafs, when clipped into flat bits, each about two or three grains in weight, and about a quarter of a fquare inch in furface, and when diffolved in nitrous acid properly diluted, yield nitrous air very equably; but if iron be ufed, the pieces of it fhould be larger and fewer; in ftiort, it fliould prefent a much lefs furface to the diluted acid ; otherwife the increafe of heat in the procefs, and the rapid production of N°J- 3 logy. Sea.xnr. elaftic fluid, render the operation both difficult and OfArtificial dangerous for the operator. Airs- As the nitrous air is moftly neceffary to try the goodnefs of refpirable air, it is of great confequence l9° to make it always of one conftant degree of goodnefs.; ^ e but this object is anfwered by diffolving fubftances of the^beft. * a very homologous nature in the nitrous acid; there¬ fore it is plain, that the metals whofe nature is more uniform muft be .preferred for this purpofe. Accord¬ ingly, brafs yields nitrous air of a more uniform nature than iron : copper is fuperior to brafs ; but pure mer¬ cury is ftill fuperior to copper: and indeed this is the metal which, confidering its nature, uniformity of fub¬ ftance, and eafy folution, is upon the whole the moft ufeful for .this purpofe. It has been generally obferved, that felid vegetable fubftances, when diffolved ijr nitrous acid, yield more nitrous air than the animal fubftances, though this ni¬ trous air is not fo pure as that obtained from metals. Sometimes it contains fome fixed air, and a good deal of inflammable air, which is moftly produced to¬ wards the end of the procefs. On the other hand, the nitrous air extracted from animal-fubftances generally contains a good deal of phlogifticated air, and fome- times fome fixed air. In order to obtain nitrous air from the folution of animal and vegetable fubftances in nitrous acid, often fome degree of heat muft be ap¬ plied to the phial. The acid alfo fometimes muft be very concentrated, and in other cafes it muft be dilu¬ ted ; but it is hardly worth while, or practicable, to determine with exaCtnefs all thofe particular cafes. To make Nitrous /iir.—The metal, viz. copper, brafs, or mercury, is firft put into the bottle (which, as well as the whole procefs, is the fame as that de- fcribed for fixed Air), fo as to fill about one-third of the fame ; then fome water is poured into the bottle, fo as juft to cover the metal-filings; and laftly, the ni¬ trous acid is added, the quantity of which, when ftrong, fhould be about one-third or half the quantity of the water. The fmell of the nitrous gas is very penetra¬ ting and offenfive, and occafions a red fmoke as foon as it comes into contad with the common air ; hence, whenever any of it efcapes from the bottle, it may be obferved not only by the iinell, but alfo by the flight red colour. In order to obferve the principal property of this elaftic fluid, which is that of diminifhing the bulk of common air, let a glafs tube, clofed at one end, and gbout nine inches long, and half or three quarters of an inch in diameter, be filled with water, and inverted in water; then take a fmall phial, of about half as ounce-meafure, filled with common air, and plunging it under the water contained in the fame bafin where the inverted tube is kept, let that quantity of air en¬ ter into the tube, which will go to the top of it, the water fubfiding accordingly. Let a mark be made, either with a file or by flicking foft wax on the tube, juft oppofite to the furface of the water in it, which will mark how much of the tube is filled by that given meafure of air. After the fame manner, fill the fame fmall phial (which we fhall call the meafure) again with air; throw that air into the tube, and put a mark on the tube coinciding with the level of the water in it. In this manner let four or five meafures be marked on the tube. Now, if three meafures of common air are put Sea. XIII.

In what manner a difference fo enormous can take place, between philofophers in other refpefts fo accu¬ rate, we can by no means determine. It is plain, however, that if 27,000 inches of common air are ne- ceffary for a perfon in one hour, the fame quantity of dephlogifticated air cannot be breathed longer than four hours, nor even fo long, with any real advantage. Mr Cavallo indeed allows only 12000 inches for four hours ; but though this might no doubt.fuftain life for that time, the perfon muft at beil expert nothing from it fuperior to the common atmofpere, if he was not materially injured by it. Avery readymethod of procuring dephlogifticated air in large quantity, is by means of nitre; and on the fup- pofition that 12,000 inches are fufficient for four hours, (or for 40 hours, as he limits the Abbe Fontana’s fuppo- fition), Mr Gavallo proceeds in the:following manner: “ The inftruments neceffary for the produftion of de¬ phlogifticated air from nitre are the following; viz. earthen retorts, or earthen veffels with a ftraight neck, fomewhat in the fhape of Florence flafks, but with a longer neck, thefe being cheaper than the retorts, and anfwering as well;—a fmall furnace, in which the earthen retort, muft be kept red-hot; a common chimney-fire is not fufficient.. Thefe furnaces may be very eafily made out of large black lead crucibles. The nitre muft be put into the retort or other veffel, fo as to fill half or nearly three quarters of its belly ; then a bent glafs tube is luted to the neck of the ear¬ then veffel, in fuch a manner as not to let any elaftic fluid efcape into the open air. The beft lute or ce¬ ment for this or fimilar purpofes is made by mixing to¬ gether whiting and drying oil. The retort being put into the furnace, muft be furrounded with lighted charcoal, which is to be fupplied according as it waftes: in ftiort, the belly of the retort muft be kept quite red-hot, or rather white-hot, for about three hours at leaft. If, inftead of the retort, the other defcribed earthen veffel be ufed, care fliould be had to place it with the neck as little inclined to the horizon as pof- fible, left the nitre ftiould ftop the neck and break it.” The air is then to be received into large glafs jars, as is ufual in other experiments on air. “ The retort or other earthen veffel that is ufed for this purpofe cannot ferve for more than once, becaufe it generally breaks in cooling; and befides, the de- eompofed nitre cannot eafily be taken out of it. The retort capable of holding a pound of nitre (the quan¬ tity neceffary for producing 12,000 cubic inches of dephlogifticated air) for this operation, cofts at leaft half-a-crown ; the other earthen veffels in the lhape of Florence flail:;;, but with longer necks, coft about l8d. a-piece, or 2 s. } fo that the price of thefe veffels forms a confiderable part of the expence. If glafs veffels are employed, the nitre will not yield near fo much air, though of a purer fort, becaufe the glafs veffels cannot endure fuch a great fire as the earthen ones. The retorts of metal, or at leaft of thofe metals which are moft ufually employed for this purpofe, viz. iron and copper, phlogifticate in a great meafure the air as foon as produced. Confidering, then, all thefe circumftances, it appears, that when a perfon has all the LOGY. Sea. xm. ufual apparatus and furnace, the expences at prefent Of Artificial neceffary in London for the produ&ion of 12,000 cu- Air-* hie inches of dephlogiftieated air, (viz. the price of one u“—v— pound of nitre, of an earthen retort or other veffel, and of charcoal), amount to about 4s. or 4s. 6d.” Another method of preparing dephlogifticated air is, by blowing that of the common atmofphere thro* melted nitre. In this procefs the phlogifton contained in the atmofphere is gradually confumed, by detonating with the acid of the nitre, and therefore iffues much more pure than before. This method has the appear¬ ance at firft of being much eafier and more commodious than the former; but as it is impoffible to mix the at- mofperic air fo exaftly with the melted nitre that every particle of the one may come in contact with every particle of the other, it is plain that the former me¬ thod muft be preferable ; not to mention that it will be found exceedingly troublefome to blow the air through the nitre, as the latter will be perpetually apt to cool and concrete into lumps by the cold blaft. $ 5. To procure Vitriolic Acid Air,—This confifts’of the vitriolic acid, united with fome phlogifton,which vo¬ latilizes and renders it capable of affuming the form of a permanently elaftic fluid. To obtain it, fome ftrong concentrated vitriolic acid muft be put into the ufual bottle, together with fome fubftance capable of fur- nifhing phlogifton. Olive oil anfwers very well. The oil of vitriol fhould be about three or four times as much as the fweet oil, and both together fhould fill about one-third or half the bottle. A gentle degree of heat is then required, in order to let thefe materials yield any elaftic fluid ; which may be done by apply¬ ing the flame of a wax taper, as diredted above for the produftion of dephlogifticated air. $ 6. To procure Marine Acid Air, which is no o- ther than the marine acid itfelf, and which without any addition becomes a permanently elaftic fluid ; put fome fea-falt, or common kitchen fait, into the ufual bottle in which the materials for producing elaftic fluids are generally put, fo as to fill about a fourth part of it, and upon this fait pour a fmall quantity of good con¬ centrated vitriolic acid; then apply the bent tube to the bottle, and introduce it through the quickfilver into the receiver, filled with and inverted in quickfilver after the ufual method, and the elaftic fluid is copi- oufly produced. $ 7. To procure Nitrous Acid Air.—This may be obtained from heated nitrous acid, the vapour of which acquires a permanent elafticity, and it has been found to remain uncondenfed into a vifible fluid by any cold to which it has been hitherto expofed. The great dif¬ ficulty is to find a fluid capable of confining this acid air; becaufe it is eafily and abundantly abforbed by water, which is one of its properties by which it differs from nitrous air. It a&s upon quickfiiver, and alfo up¬ on oils: hence its examination cannot be made but very imperfectly ; for fubftances muft be expofed to it, or mixed with it, whilft it is actually changing its na¬ ture by aCting on the mercury or other fluid that con- - fines it. When water has abforbed a good quantity of this elaftic fluid, it acquires the properties of nitrous acid; and when heated, it yields a large quantity of nitrous airj Sea. XIII. AERO OfArtificial air, viz. a quantity many times greater than that which , •Air9~ , water is won't to imbibe of it by agitation, or by any v "" known means. When the nitrous acid air is combined with effen- tial oils, a confiderable effervefcence and heat are pro¬ duced, nearly in the fame manner as when the nitrous acid itfelf is poured upon thofe oils. § 8. Fluor /4cid Air.—Put fome of thofe minerals called fiuors, or fiifible /pars, pulverized, into the ufual bottle, and upon it pour fome concentrated oil of vi¬ triol; then adapt the bent tube, &c. The fluor acid LOGY. 195 air is at firft produced without the help of heat; but in Of Artificial a fhort time it will be necelfary to apply the flame of ^r3, . a candle to the bottle, by which means a confiderable quantity of this elaftic fluid is obtained. § 9. Alkaline Let the ufual bottle be about half filled with volatile fpirit of fal ammoniac; and after applying the bent tube, &c. let the flame of a candle be brought under the bottle, by which means the al¬ kaline air will be produced copioufly.

AEROSTATION A ERG S T A T I O N 198 IS a fcience newly introduced into the Encyclopaedia. The word} in its primitive fenfe, denotes the fcience of fufpending- weights in the . air; but in its modern ac¬ ceptation, it lignifies aerial navigation, or the art of na¬ vigating through the atmofphere. Hence alfo the ma¬ chines which are employed for this purpofe are called aerojlats, or aeroftatic machines; and from their globu¬ lar fhape, air-balloons. The romances of almoft every nation have recorded inftances of perfons being carried through the air, both 1 by the agency of fpirits and by mechanical inventions; Lord Bacon but till the time of the celebrated Lord Bacon, no ra- I'ftd'th" t^ona^ principle appears ever to have been thought of true prim by which this might be accompliihed. Before that ciples of ae- time, indeed, Friar Bacon had written upon the fubjedt; rotation, and many had been of opinion, that, by means of arti¬ ficial wings, fixed to the arms or legs, a man might fly 2, as well as a bird: but thefe opinions were thoroughly Impofiibili- refuted by Borelli in his treatife De Motu Animalium, ty of flying where, from a comparifon between the power of the nfcalmeans niufcles which move the wings of a bird, and thofe which move the arms of a man, he demonftrates that the latter are utterly infufficient to ftrike the air with 'fuch force as to raife him from the ground. It can¬ not be denied, however, that wings of this kind, if properly conftrudted, and dexteroufly managed, might be fufficient to break the fall of a human body from an high place, fo that fome adventurers in this way might poflibly come off with fafety ; though by far the great- eft number of thofe who have raflily adopted fuch fchemes, have either loft their lives or limbs in the at- 3 tempt. Scheme of In the year 1672, Biftiop Wilkins publifhed a trea- BifliopWil-tife> intitled, The Difcovery of the New World; in .Albemisde which l16 mentions, though in a very indittindt and Saxonia. confufed manner, the true principle on which the air is navigable ; quoting, from Albertus de Saxonia and •Francis Mendoca, “ that the air is in fome part of it -navigable : and upon this ftatic principle, any brafs or iron veffel (fuppofe a kettle), whofe fubftance is much heavier than that of wafer, yet being filled with the lighter air, it will fwim upon it and not fink. So fup¬ pofe a cup or wooden veflel upon the outward borders of this elementary air, the capacity of it being filled with fire, or rather ethereal air, it muft neceffarily, up¬ on the fame ground, remain fwimming there, and of it- felf can no more fall than an empty fliip can fink.” This idea, however, he did not by any means purfue, but refted his hopes entirely upon mechanical motions, to be accompliflied by the mere ftrength of a man, or by fprings, &c. and which have been demonftrated in- 4 capable of anfwering any ufeful purpofe. Bifliop La- The only perfon who brought his fcheme of flying na’sfcheoie. to any kind of rational principle was the Jefuit Francis Lana, cotemporary with Bifiiop Wilkins. He, being acquainted with the real weight of the atmofphere, j uftly concluded, that if a globular veflel wrere exhauft- ed of air, it would weigh lefs than before ; and confi- dering that the folid contents of vefiels increafe in much greater proportion than their furfaces; he fuppo- fed that a metalline veflel might be made fo large, that, when emptied of its air, it would be able not only to raife itfelf in the atmofphere, but to carry up pafiengers along with it; and he made a number of calculations neceflary for putting the projedt in execu¬ tion. But though the theory was here unexception¬ able, the means propofed were certainly infufficient to accomplilh the end: for a veflel of copper, made fo thin as was necefiary to make it float in the atmo¬ fphere, would be utterly unable to refill the external preflure ; which being demonftrated by thofe fkilled in mechanics, no attempt was made on that principle. ^ In the year 1709, however, as we were infonned by Strange a letter publilhed in France in 1784, a Portuguefe propofal of projector, Friar Gufman, applied to the king for en- Fr‘ar Gul~* couragement to his invention of a flying machine. The man* principle on which this was conftrudted, if indeed it had any principle, feems to have been that of the pa¬ per kite. The machine was conftru&ed in form of a bird, and contained feveral tubes through which the wind was to pafs, in ordei* to fill a kind of fails, which were to elevate it; and when the wind was deficient, the fame effedl was to be performed by means of bel¬ lows concealed within the body of the machine. The afeent was alfo to be promoted by the eleftric attrac¬ tion of pieces of amber placed in the top, and by two fpheres inclofing magnets in the fame fituation. Thefe childilh inventions (how the low ftate of fci¬ ence at that time in Portugal, efpecially as the king, in order to encourage him to farther exertions in fuch an ufeful invention, granted him the firft vacant place in his college of Barcelos or Santarem, with the firft profeflbrlhip in the Univerfity of Coimbra, and an an¬ nual penfion of 600,000 reis during his life. Of this De Gufman,. it is alfo related, that in the year 1736, he made a wicker balket of about feven or eight feet diameter, and covered with paper, which raifed itfelf about 200 feet in the air, and the effedl was generally attributed to witchcraft. In the year 1766, Mr Henry Cavendilh afeertained Loflibility the weight and other properties of inflammable air, de- ° termining it to be at leaft feven times lighter than air thought common air. Soon after which, it occurred to Dr of by Dr Black, that perhaps a thin bag filled with inflammable an<* air might be buoyed up by the common atmofphere ; rt'ava °* and he thought of having the allantois of a calf prepa¬ red for this purpofe : but his other avocations prevent¬ ed him from profecuting the experiment. The fame thought occurred fome years afterwards to Mr Cavallo ; and he has the honour of being the firft who made ex¬ periments on the fubjedl. He firft tried bladders ; but the thinneft of thefe, however Well feraped and prepa¬ red, were found too heavy. He then tried Chinefc paper ; but that proved fo permeable, that the vapour paffed through it like water through a fieve. His ex¬ periments, therefore, mr^le in the year 1782, proceed- I99 AEROSTATION. ed no farther than blowing up foap-bubbles with in¬ flammable air, which afcended rapidly to the cieling, ? and broke againft it. Aeroftation But' while the difcovery of the art of aeroftation difenvered feemed thus on the point of being made in Britain, it Mont°ol' was at once announced in France, and that from a tier. S ‘ quarter whence nothing of the kind was to have been expected. Two brothers, Stephen and John Mont¬ golfier, natives of Annonay, and matters of a confider- able paper-man ufaftory there, had turned their thoughts towards this project as early as the middle of the year 1782. The idea was firft fuggefted by the natural afcent of the fmoke and clouds in the atmofphere; and their defign was to form an artificial cloud, by inclofxng the fmoke in a bag, and making it carry up the cover- g ing along with it. Towards the middle of November Account of that year, the experiment was made at Avignon with his experi- a fine filk bag of a parallelepiped fhape. By applying jnent?. burning paper to the lower aperture, the air was rare¬ fied, and the bag afcended in the atmofphere, and ftruck rapidly againft the ceiling. On repeating the experiment in the open air, it rofe to the height of about 70 feet. An experiment on a more enlarged fcale was now projected; and a new machine, containing about 650 cubic feet, was made, which broke the cords that con¬ fined it, and rofe to the height of about 600 feet. A- nother of 35 feet in diameter rofe about 1000 feet high, and fell to the ground three quarters of a mile from the place where it afcended. A public exhibition was next made on the 5th of June 1783, at Annonay, where a vaft number of fpeftators affembled. An im- menfe bag of linen, lined with paper, and containing upwards of 23,000 cubic feet, was found to have a power of lifting about 500 pounds, including its own weight. The operation was begun by burning chop¬ ped ftraw and wool under the aperture of the machine, which immediately began to fwell; and after being fet at liberty, afcended into the atmofphere. In ten mi¬ nutes it had afcended 6000 feet; and when its force was exhaufted, it fell to the ground at the diftance of 7668 feet from the place from whence it fet out. Socm after this, one of the brothers arrived at Paris, where he was invited by the Academy of Sciences to repeat his experiments at their expence. In confe- quence of this invitation, he conftrufled, in a garden in the Fauxbourg of St Germain, a large balloon of an elliptical form. In a preliminary experiment, this ma¬ chine lifted up from the ground eight perfons who held it, and would have carried them all off if more had not quickly come to their afliftance. Next day the expe¬ riment was repeated in prefenee of the members of the academy ; the machine was filled by the combuftion of 50 pounds of ftraw made up in fmalF bundles, upon which about 12 pounds of chopped wool were thrown at intervals. The ufual fuccefs attended this • exhibi¬ tion : The machine foon fwelled; endeavoured, to a- feend; and immediately after fuftained itfelf in the air, together with the charge of between 4 and 500 pounds weights It was evident , that it would have afcended to a great height; but as it was defigned to repeat the experiment before the king and royal family at Verfailles, the cords by which it was tied down were not cut. But in confequence of a violent rain and wind which happened at this, time, the machine was 2 fo far damaged, that it became neceflary to prepare a new one for the time that it had been determined to honour the experiment with the royal prefencC; and fuch expedition was ufed, that this vaft machine, of near 60 feet in height and 43 in diameter, was made, painted with water-colours both within and without, and finely decorated, in no more than four days and four nights. Along with this machine was fent a Some ani- wicker cage, containing a fheep, a cock, and a duck, ™als ^e|y. which were the firft animals ever fent through the at- mofphere. The full fuccefs of the experiment was pre¬ vented by a violent guft of wind which tore the cloth in two places near the top before it afcended: How¬ ever, it rofe to the height of 1440 feet; and, after re¬ maining in the air about eight minutes, fell to the ground at the diftance of 10,200 feet from the place ■ of its fetting out. The animals were not in' the leaft hurt. 10 The great power of thefe aeroftatic machines, and Mr Pilatre their very gradual defeent in falling to the ground, had originally fhowed that they were capable of tranfport-rial navigaI ing people through the air with all imaginable fafety ; tor. and this was further confirmed by the experiment al¬ ready mentioned. As Mr Montgolfier, therefore, propofed to make a new aeroftatic machine of a firmer and better conftruftion than the former, Mr Pilatre de Rozier offered himfelf to be the firft aerial adven¬ turer. This new machine was conftrufted in a garden in the Fauxbourg of St Antoine. It was of an oval ftiape, about 48 feet in diameter and 74 in height; elegantly painted on the outfide with the figns of the zodiac, ciphers of the king’s name, and other ornaments. A proper gallery, grate, See. were appended in the man¬ ner afterwards deferibed; fo that it was eafy for the perfon who afcended to fupply the fire with fuel, and thus keep up the machine as long as he pleafed. The . weight of the whole apparatus was upwards of 1600 pounds. The experiment was performed on the 15th n of October 1783. Mr Pilatre having placed himfelf Account of 1 in the gallery, the machine-waa inflated, and permit- ted to afeend to the height of 84 feet, where he kept V°5 a* it afloat for about four minutes and a half; after6 which it defeended very- gently :. and ‘fuch was its tendency to afeend, that it rebounded to a confiderable height after touching the ground. Two days after, he repeated the experiment with the fame fuccefs as . before; but the wind being ftrong, the machine did not fuftain itfelf fo well as formerly. On repeating the experiment in calmer weather, he afcended to . the height of 210 feet. His next afcent was 262 feet; and- in the defeent, a guft of wind having blown the machine over feime large trees of an adjoin¬ ing garden, Mr Pilatre fuddenly extricated himfelf from fo dangerous a fituation, by throwing fome ftraw and chopped wool on the fire, which raifed him at once to a fufficient height. On defeending again, he once more raifed himfelf to a proper height by throw¬ ing ftraw on the fire. Some time after, he afcended in company with Mr Girond de Villette to the height of 330 feet; hovering -over Paris at leaft nine minutes in fight of all the inhabitants, and the machine keep¬ ing all the while perfectly fteady. Thefe experiments had fhown, that the aeroftatic machines might be raifed or lowered at the pleafure of the. .2.00 AEROSTATION. Hifloryv the perfons who afcended : they had likewife dxfcover- ed, that the keeping them faft with ropes was no advantage ; but, on the contrary, that this was attend¬ ed with inconvenience and hazard. On the 21ft of November 1783, therefore, M. Pilatre determined to undertake an aerial voyage in which the machine fliould be fully fet at liberty. Every thing being got in rea- dinefs, the balloon was filled in a few minutes ; and M. Pilatre placed himfelf in the gallery, counterpoifed by the Marquis d’Arlandes, who occupied the .other fide. It was intended to make fome preliminaiy ex¬ periments on the afcending power of the machine: -but the violence of the wind prevented this from being .done, and even damaged the balloon effentiallyfo that it would have been entirely deftroyed had not timely alfiftance been given.. The extraordinary exer¬ tions of the workmen, however, repaired it again in two hours, and the adventurers fet out. They met with no inconvenience during their voyage, which laded about 25 minutes; during which, time they had palled over a fpace of above five miles.—From the account given by the Marquis d’Arlandes, it ap¬ pears that they met with feveral different currents of air; the effedt of which was, to give a very fenfible Ihocfe to the machine, and the diredtion of the motion feemed to be from the upper part downwards. It ap¬ pears alfo that they were in fome danger of having the balloon burnt altogether; as the Marquis obferved fe¬ veral round holes made by the fire in the lower part of it, which alarmed him confiderably, and indeed not without reafon. However, the progrefs of the fire was eafily flopped by the application of a wet fpunge, and all appearance of danger ceafed in a very fhort time. Montgol- This voyage of M. Pilatre and the Marquis d’Ar- fier’s ma- landes may be faid to conclude the. hiflory of thofe chines fu- aeroftatic machines which are elevated by means of r-feded hy fire; for though many other attempts have been made witfiin-' uPon the fame principle, molt of them have either flammable proved unfuccefsful or were of little confequence. They air. have therefore given place to the other kind, filled with inflammable air; which, by reafon of its fmaller fpe- cific gravity, is both more manageable, and capable of performing voyages of greater length, as -it does not require to be fupplied with fuel like the others. This was invented a very fhort time after the difcovery had been made by M. Montgolfier. This gentleman had indeed defigned to keep his method in fome degree a fecret from the world ; but as it could not be conceal¬ ed, that a bag filled with any kind of fluid lighter than the common atmofphere would rife in it, inflammable air was naturally thought of as -a proper fuccedaneum 13 for the rarefied air of M. Montgolfier. The firfl ex- Experi- periment was made by two brothers Meffrs Roberts, Meffrs^ anh M. Charles a profeffor of experimental philofo- Chai les and phy* The bag'which contained the gas was compo- lloberts. fed of lutefiring, varnifhed over with a folution of the elaflic gum called caoutchouc.;, and that with which they made their firfl effay was only about 13 Englifh feet in diameter. Many difficulties occurred in filling it with the inflammable air, chiefly owing to their ig¬ norance of the proper apparatus; infomuch, that, af¬ ter a. whole day’s labour from nine in the' morning, they had got the balloon only one third part full. Next morning they were furprifed to find that it had fully inflated of itfelf during the night: but Upon in- 14 1 quiry, it was found, that they had inadvertently left1,1 w|la£ . ^ open a flop-cock connected with the balloon, by which.j,aqoon ;■ the common air gaining accefs, had mixed itfelf with partly filled the inflammable air; forming a compound flill lighter may inflate than the common atmofphere, but not fufficiently light ^t^' to anfwer the purpofes of aeroflation. Thus they were obliged to renew their operation ; and, by fix o’clock in the evening of next day, they found the machine confiderably lighter than the common air ; and, in an hour after, it made a confiderable effort to afcend. The public exhibition, however, had been announced only for the third day after ; fo that the balloon was allowed to remain in an inflated flate for a whole day; I? during which they found it had loft a power of afcent Lots of j equal to about three pounds, being one feventh part power in of the whole. When it was at laft fet at liberty, after |^r : having been well filled with inflammable air, it was 35 pounds lighter than an equal bulk of common air. It remained in the atmofphere only three quarters of an hour, during which it had traverfed 15 miles. Its fudden defcent was fuppofed to have been owing to a rupture which had taken place when it afcended into the higher regions of the atmofphere. ,5 The fuccefs of this experiment, and the aerial voy-Firft aerial age made by Meffrs Rozier and Arlandes, naturally voyage of fuggefted the idea'of undertaking fomething of the"sand fame kind with a balloon filled with inflammable air. Roberts. The machine ufed on this occafion was formed of gores of filk, covered over with a varnifh made of caoutchouc, of a fpherical figure, and meafuring 274- feet in dia¬ meter. A net was fpread over the upper hemifphere, and was faftened to an hoop which paffed round the middle of the balloon. To this a fort of car, or ra¬ ther boat, was fufpended by ropes, in fuch a manner as to hang a few. feet below the lower part of the bal¬ loon ; and, in order to prevent the burfling of the ma¬ chine, a valve was placed in it; by opening of which fome of the inflammable air might be bccafionally let out. A long filken pipe communicated with the bal¬ loon, by means of which it was filled. The boat was made of bafket-work, covered with painted linen, and beautifully ornamented ; being 8 feet long, 4 broad, and 3t deep ; its weight 130 pounds. At this time, however, as at the former, they met with great difficul¬ ties in filling the machine with inflammable air, owing to their ignorance of the moft proper apparatus. But at laft, all obftacles being removed, the two adventu¬ rers took their feats at three quarters after one in the afternoon of the firft of December 1783. Perfons fltilled in mathematics were conveniently ftationed with proper inftruments to calculate the height, velocity, &c. of the balloon. The weight of the whole appa¬ ratus, including that of the two adventurers, was found to be 6044-'pounds, and the power of afcent when they fet out was 20 pounds; fo that the whole difference betwixt the weight of this balloon and an equal bulk of common air was 624 pounds. But the weight of I7 common atmofphere difplaced by the inflammable gas Specific was calculated to be 771 pounds, fo that there remains gravity of 147 for the weight of the latter; and this calculation makes it only 5^ times lighter than common air. ™js m At the time the balloon left the ground, the ther- voyage, mometer flood at g° of Fahrenheit’s fcale, and the quicklilver in the barometer at 30.18 inches; and, by means AjKMOSTA 7Vf^V Vei-faillep Plate H.

Hiflory. which a deviation of about 80 degrees would have been obtained. “ We had already obferved (fay they), that if we did not deviate more than 12 degrees, it was becaufe the wind carried us at the rate of 24 miles an hour ; and it is natural to judge, that, if the wind had been twice as ftrong as it was, we ftiould not have deviated more than one-half of what we adually did; and, on the contrary, if the wind had been only half as ftrong, our deviation would have been proportionably great- er.” 3I Flaving thus related all that has been done with re- Contrivan* gard to the conducting of aeroftatic machines through ccs ufed t0 the atmofphere, we ftiall now relate the attempts that have been made to leflen their expence, by falling upon flammable fome contrivance to afcend without throwing out bal- air. laft, and to defcend without lofing any of the inflam- 3a mable air. The firft attempt of this kind was made Voyage of by the Duke de Chartres; who, on the 15th of July the Duke 1784, afcended with the two brothers, Charles and Ro- de Chartres, bert, from the Park of St Cloud. The balloon was of an oblong form, made to afcend with its longeft dia¬ meter horizontally, and meafured 55 feet in length and 24 in breadth. It contained within it a fmaller balloon filled with common air; by blowing into which with a pair of bellows, and thus throwing in a confi- derable quantity of common air, it was fuppofed that the machine Would become fufficiently heavy to defcend, efpecially as, by the inflation of the internal bag, the inflammable air in the external one would be condenfed into a fmaller fpace, and thus become fpecifically hea¬ vier. The voyage, however, was attended with fuch circumftances as rendered it impoffible to know what would have been the event of the fcheme. The power of afcent with which they fet out, feems to have been very great; as, in three minutes after parting with the ground, they were loft in the clouds, and involved in 33 fuch a denfe vapour that they could fee neither the fky Is involved nor the earth. In this fituation they feemed to be dark attacked by a whirlwind, which, befides turning the jt'ackeTby balloon three times round from right to left, {hocked, a W}1!F[. and beat it fo about, that they were rendered incapable wind, of ufing any of the means propofed for dire&ing their courfe, and the filk fluff of which the helm had been compofed was even torn away. No feene can be con¬ ceived more terrible than that in which they were now involved. An immenfe ocean of fhapelefs clouds rolled one upon another below them, and feemed to prevent any return to the earth, which ftill continued invifible, while the agitation of the balloon became greater every moment. In this extremity they cut the cords which held the interior balloon, and of confequence it fell down upon the aperture of the tube that came from the large balloon into the boat, and flopped it up. They were then driven upwards by a guft of wind from below, which carried them to the top of that ftormy vapour in which they had been involved. They now faw the fun without a cloud ; but the heat of his rays, with the diminifhed denfity of the atmofphere, had fuch an effedft on the inflammable air, that the balloon feem¬ ed every moment ready to burft. To prevent this they introduced a flick through the tube, in order to pufh away the inner balloon from its aperture ; but the ex- panfion of the inflammable air pulhed it fo clofe, that ! AEROSTATION. Hiftory. all attempts of this kind proved ineffe&ual. It was now, however, become absolutely neceffary to give vent to a very confiderable quantity of the inflammable air; for which purpofe the Duke de Chartres himfelf bored two holes in the balloon, which tore open for the length ©f feven or eight feet. On this they defcended with great rapidity ; and would have fallen into a lake, had they not haftily thrown out 60 pounds of ballaft, which enabled them juft to reach the water’s edge. The fuccefs of the Scheme for raifing or lowering aeroftatic machines by means of bags filled with com¬ mon air being thus rendered dubious, another method was thought of. This was to put a fmall aeroftatic ' machine with rarefied air under an inflammable air- balloon, but at fuch a diftatrce that the inflammable air ©f the latter might be perfectly out of the reach of the fire ufed for inflating the former; and thus, by increa- fing or diminifliing the fire in the finall machine, the 34 abfolute weiglit of the whole would be confiderably di- Unfortu- minifhed or augmented. This fcheme was unhappily an^ de at if6 Put *n execut‘on hy the celebrated Mr Pilatre de Ro¬ of Meffrs z^er> and another gentleman named Mr Romaine. Their Rozierand inflammable-air balloon was about 37 feet in diameter,! Romaine. and the power of the rarefied-air one was equivalent to about 60 pounds. They afcended without any appear¬ ance of danger or finifter accident; but had not been long in the atmofphere when the inflammable-air bal¬ loon was feen to fwell very confiderably, at the fame time that the aeronauts were obferved, by means of te- lefcopes, very anxious to get down, and bufied in pull¬ ing the valve and opening the appendages to the bal¬ loon, in order to facilitate the efeape of as much in¬ flammable air as poffible. A Ihort time after this the whole machine was on fire, when they had then attained the height of about three quarters of a mile from the * ground. No explofion was heard ; and the filk which eompofed the air-balloon continued expanded, and feemed to refill the atmofphere for about a minute ; after which it collapfed, and the remains of the appara¬ tus defcended along with the two unfortunate travellers fo rapidly, that both of them were killed. Mr Pilatre feemed to have been dead before he came to the ground; but Mr Romaine was alive when fome perfons came up to the place where he lay, though he expired imme¬ diately after. Thefe are the moft remarkable attempts that have been made to improve the fcience of aeroftation; tho’ a great number of other expeditions through the at¬ mofphere have taken place. But of all the voyages which had been hitherto proje&ed or put in exe- V< y?ge of cution> the m°ft daring was that of Mr Blanchard MefLBIan-and Dr Jeffries acrofs the ftraits of Dover which chard and feparate Britain from France. This took place on Jeffries the 7th of January 1785, being a clear frolly mor- StraitMrf “ing* .with a wind, barely perceptible, at N. N. W. X)pver. The operation . of filling the balloon began, at 10 o’clock, and, at three quarters after twelve, every thing was ready for their departure. At one o’clock Mr Blanchard defired the boat to be pufhed off, which now flood only two feet diftant from that precipice fo finely defcribed by Shakefpeare in his tragedy of King Lear. As the balloon was fcarcely fufficient to cany two, they were obliged to. throw out all their ballaft except three bags of 10 pounds each ; when they at laft rofe gently, though making very little _ way on account of there being fo little wind. At a quarter after one o’clock, the barometer, which on the cliff flood at 29.7 inches, was now fallen to 27.3, and the weather proved fine and warm. They had now a moft beautiful profpeft of the fouth coaft of England, and were able to count'37 villages upon it. After palling over feveral veffels, they found that the balloon, at 50 minutes after one, was defcending, on which they threw out a fack and an half of ballaft; but as they faw that it ftill defcended, and that with much greater velocity than before, they now threw out all the ballaft. This ftill proving ineffeAual, they next threw out a parcel of books they carried along with them, which made the balloon afcend, when they were about midway betwixt France and England.. At a quarter pall two, finding themfelves again defcending, they threw away the re- • mainder of their books, and, ten mimites after, they had a moft enchanting profpeft of the French coaft. Still, however, the machine defcended; and as they had now no more ballaft; they were fain to throw away their provifions for eating, the wipgs of their boat, and every other moveable they could eafily fpare. “ We threw- away, fays Dr Jeffries, our only bottle, which, in its defcent, call out a fleam like fmoke, with a ruffl¬ ing noife; and when it ftruck the water, wo heard and felt the Ihock very perceptibly on our car and balloon.’> All this proving infufficient to Hop the defcent of the balloon, they next threw out their anchors and cords,. und at laft ftripped off their cloths, faftening themfelves to certain flings, and intending to cut away the boat as their laft refource.. They had now the fatisfa&ion, however, to find that they were riling ; and as they paffed over the high lands between Cape'Blanc and Calais, the machine rofe very fall, and carried them to . a greater height than they had been at any former part of their voyage. They defcended fafely among fome trees in the foreft of Guiennes, where there was juft opening enough to admit them. It would be tedious as well as unneceffary to recount all the other aerial voyages that have been performed in our own or other countries : It appeared fufficient for the purpofe of this article to notice thofe which were moft remarkable and interefting ; and therefore an account of the ingenious Mr-Baldwin’s excurfion from Chefter, alluded. to .albove, Ihall. now clofe our enu¬ meration. On the 8th of September 1-785, at .forty minutes ; pall one P. M. Mr Baldwin afcended from Chefter in Mr Lunardi’s(A) balloon. After traverfingin a variety of different directions, he firft alighted, at .28 minutes after three, about twelve, miles from Chefter, in the neighbourhood of. Frodfham; then reafeending and purfuing his excurfion,. he finally landed at Rixton mofa, five miles N. N. E. of Wavington, and 25 miles from Chefter. Mr Baldwin has publilhed his Obferva- tions and Remarks made during his voyage, and taken from .minutes. Our limits will not admit of relating C c 2 many (a) Of this gentleman’s adventurous excurfions moft people have been witneffes ; and therefore it appeared.! unaeceffary to take up room with an account of them in this article. . 204 A E R O S T A T I O N. Hiftory many of his obfervations; but the few following are fome of the moft important and curious. “ The fen- fation of afcending is compared to that of a ftrong preflure from the bottom of the car upwards againft the foies of his feet At the diftance of what appeared to him feven miles from the earth, though by the ba¬ rometer fcarcely a mile and a half, he had a grand and moft enchanting view of the city of Chefter and its adjacent places below. The river Dee appeared of a red colour; the city very diminutive; and the town entirely blue. The whole appeared a perfeft plain, the higheft building having no apparent height, but reduced all to the fame level, and the whole terreftrial profpeft appeared like a coloured map. Juft after his firft afcent, being in a well-watered and maritime part of the country, he obferved a remarkable and regular tendency of the balloon towards the fea; but ftiortly after rifing into another current of air, he efcaped the danger; this upper current, he fays, was vifible to him at the time of his afcent, by a lofty found ftratum of clouds flying in a fafe direction. The perfpeftive ap¬ pearance of things to him was very remarkable. The loweft bed df vapour that firft appeared as cloud was pure white, in detached fleeces, increafing as they rofe: they prefently coalefced, and formed, as he exprefles it, a fea of cotton, tufting here and there by the aftion of the air in the undifturbed part of the clouds. The whole became an extended white floor of cloud, the upper furface being fmooth and even. Above this white floor he obferved, at great and une¬ qual diftances, a vaft affemblage of thunder-clouds, each parcel confifting of whole acres in the denfeft form; he compares their form and appearance to the fmoke of pieces of ordnance, which had confolidated as it were intomaffesof fnow, and penetrated through the upper furface or white floor of common clouds, there remaining wifible and at reft. Some clouds had mo¬ tions in flow and various direttions, forming an appear¬ ance truly, ftupendous and majeftic. He endeavours to convey fome idea of the fcene by a figure; (and from which fig. 13. of 2d Plate II. is copied), reprefents a circular view he had from the car of the balloon, him- felf being over the centre of the view, looking downonthe white floor of clouds and feeing the city of Chefter through an opening, which difcovered the landfcape be¬ low, limited by furrounding vapour, to lefs than two miles in diameter. The breadth of the outer margin defines his apparent height in the balloon (viz. 4 miles) above the white floor of clouds. Mr Baldwin alfo gives a curious defcription of his tracing the Ihadow of the balloon over tops of volumes of clouds. 'At firft it was final!, in fize and fltape like an egg ; but foon en- creafcd to the magnitude of the fun’s difc, ftill grow¬ ing larger, and attended with a moft captivating ap¬ pearance of an iris encircling the whole (hadow at fome diftance round it, the colours of which were remarkably brilliant. The regions did not feel colder, but rather -warmer* than below. The fun was hotteft to him when the balloon was ftationary. The difeharge pf a cannon when the balloon was at a confiderable height, was diftinctly heard by the aeronaut; and a difeharge from the fame piece, when at the height of 30 yards, fo difturbed him as to oblige him for fafety to lay hold .firmly of the cords of the balloon. At a confiderable height he poured down a pint-bottle full of water; and as the air did not oppofe a refiftancefufficient to break the fteam into fmall drops, it moftly fell down in large drops. In the courfe of the balloon’s tract it was found much affefted by the water (a circumftance ob¬ ferved in former aerial voyages). At one time the direction of the balloon kept continually over the wa¬ ter, going diredtly towards the fea, fo much as to en¬ danger the aeronaut; the mouth of the balloon was opened, and he in two minutes defeended into an under current blowing from the fea : he kept defeending, and landed at Bellair farm in Rinfley, x 2 miles from Chefter. Here he lightened his car by 31 pounds, and inftantly reafeending, was carried into the interior part of the country, performing a number of different manoeuvres. At his greateft altitude he found his refpiration free and eafy. Several bladders which he had along with him crackled and expanded very confiderably. Clouds and land, as before, appeared oh the fame level. By way of experiment, he tried the upper valve two or three times, the neck of the balloon being clofe; and re¬ marked, that the efcape of the gas was attended with a growling noife like millftones, but not near fo loud. Again, round the fliadow of the balloon, on the clouds he obferved the iris. A variety of other circumftances and appearances he met with, is fancifully deferibed; and at 53 minutes paft three he finally landed. 36 The frequency of aerial voyages, accompanied with of ac particular details of trifling and uninterefting circum-ro a 10n‘ ftances, and apparently made with a view to promote the intereft of particular perfons, regardlefs of any ad¬ vancement in knowledge, have now funk the fcience of aeroftation fo low in the opinion of moft people, that before giving any account of the moft . proper method of conftruCting thefe machines, it may feem neceffary to premife fomething concerning the ufes to which they may pofiibly be applied. Thefe, according to Mr Cavallo, are the following. “ The fmall balloons, efpecially thofe made of paper, and raifed by means of fpirit of wine, may ferve to ex¬ plore the direction of the winds ip the upper regions of the atmofphere, particularly when there is a calm below: they may ferve for fignals in various circum¬ ftances, in which no other means can be ufed; and let¬ ters or other fmall things may be eafily fent by them, as for inftance from Ihips that cannot fafely land on account of ftorms, from befieged places, iflands, or the like. The larger aeroftatic machines may anfwer all the abovementioned purpofes in a better manner; and they may, befides, be ufed as a help to a perfon who wants to afeend a mountain, a precipice, or to crofs a river ; and perhaps one of thofe machines tied to a boat by a long rope, may be, in fome cafes, a better fort of fail than any that is ufed at prefent. The largeft fort of machines, which can take up one or more men, may evidently be fubfervient to various ceconomical and phi- lofophical purpofes. Their conveying people from place to place with great fwiftnefs, and without trouble, may be of effential ufe, even if the art of guiding them in a direction different from that of the wind ihould never be difcovered. By means of thofe machines the ihape of certain feas and lands may be better afeer- tained; men may afeend to the tops of mountains they never vifited before; they may be carried over marfhy ’ssn* Principles. A E R O S and dangerous grounds; they may by that means come out of a befieged place, or an ifland; and they may, in hot climates, afcend to a cold region of the atmofphere, either to refrefh themfelves, or to obferve the ice, which is never feen below; and, in fhort, they may be thus taken to feveral places, to which human art hitherto knew of no conveyance. “ The philofophical ufes, to which thefe machines may be fubfervient, are numerous indeed; and it may be fufficient to fay, that hardly any thing which paffes in the atmofphere is known with preciiion, and that principally for w-ant of a method of afcending into it. The formation of rain, of thunder-ftorms, of vapours, hail, fnow, and meteors in general, require to be atten¬ tively examined and afcertained. The adlion of the barometer^ the refraftion and temperature of the air in various regions, the defcent of bodies, the propagation of found, &c. are fubje&s which all require a feries of obfervations and experiments, the performance of which could never have been properly expected before the difcovery of aeroftatic machines.” To thofe ufes we may add the gratification of curiofity and pleafure as a very ftrong inducement to the practice of an art, in which, with any tolerable degree of cau¬ tion, there appears not to be the fmalleft danger. Every one who has tried the experiment teftifies, that the beauty of the profpedt afforded by an afcent, or the pleafure of being conveyed through the atmo¬ fphere, cannot be exceeded. No one has felt the leaft of that giddinefs confequent upon looking from the top of a very high building or of a precipice, nor have they any of the ficknefs arifing from the motion of a veffel at fea. Many have Jbeen carried by bal¬ loons at the rate of 30, 40, or even 50 miles an hour, without feeling the leaft inconvenience, or even agi¬ tation of the wind; the reafon of which is, that as the machine moves with nearly the velocity of the wind itfelf, they are always in a calm, and without uneafi- nefs. Some have apprehended danger from the elec¬ tricity of the atmofphere; and have thought that a ftroke of lightning, or the fmalleft eleftric fpark, hap¬ pening near a balloon, might fet fire to the inflamma¬ ble air. and deftroy both the machine and the adven¬ turers. Mr Cavallo has fuggefted feveral confiderations for diminiihing apprehenfions of this kind. Balloons have been already raifed in every feafon of the year, and even when thunder has been heard, without in¬ jury. Jn cafe of danger, the aeronauts may either de- fcend to the earth, or afcend above the region of the clouds and thunder-ftorms. Befides, as balloons are formed of materials that are not conductors of electri¬ city, they are not likely to receive ftrokes, efpecially as by being encompaffed with air they ftand infulated. Moreover, inflammable air by itfelf, or unmixed with a certain quantity of common air, will not burn ; fo that if an eleftric fpark ftiould happen to pafs through the balloon, it would not fet fire to the inflammable 37 air, unlefs a hole was made in the covering. Principles The general principles of aeroftation are fo little tiener° ^ different from thofe of hydroftatics, that it may feem fuperfiuous to infift much upon them. It is a fa£t univerfally known, That when a body is immerfed in any fluid, if its weight be lefs than an equal bulk of that fluid, it will rife to the furface; but if. heavier, it will fmk ; and if equal, it will remain in the place where it T A T I O N. 205 is left. For this reafon fmoke afcends into the atmo¬ fphere, and heated air in that which is colder. The 38 afcent of the latter is fliown in q. very eafy and fatis- Pxperi- factory manner by bringing a red-hot iron under one *"ent? of the feales of a balance, by which the latter is ‘n_ impuiffof* ftantly made to afcend ; for, as foon as the red-hot heated air. iron is brought under the fcale, the hot a,ir being light* er than that which is colder, afcends, and ftrikes the bottom, which is thus impelled upwards, and the op- pofite fcale defeends, as if a weight had been put in¬ to it. u Upon this Ample principle depends the whole theo¬ ry of aeroftation ; for it is the fame thing whether we render the air lighter by introducing a quantity of heat into it, or inclofing a quantity of gas fpecifically lighter than the common atmofphere in a certain fpace; both will afcend, and for the fame reafon. A cubic foot of air, by the moft accurate experiments, has been found to weigh about 554 grains, and to be ex¬ panded by every degree of heat, marked on Fahren¬ heit’s thermometer, about tW1 part of the whole. By heating a quantity of air, therefore, to 500 de¬ grees of Fahrenheit, we will juft double its bulk when the thermometer ftands at 54 in the open air, and in the fame proportion we will diminifh its weight; and if fuch a quantity of this hot air be inclofed in a bag, that the excels of the weight of an equal bulk of com¬ mon air weighs more than the bag with the air con¬ tained in it, both the bag and air will rife into the at¬ mofphere, and continue to do fo until they arrive at a place where the external air is naturally fo much rare¬ fied that the weight becomes equal; and here the whole will float. The power of hot air in raifing weights, or rather that by which it is itfelf impelled upwards, may be fliown in the- following manner: Roll up a flieet of paper into a conical form, and, by thrufting a pin in¬ to it near the apex, prevent it from unrolling. Fatten it then, by its apex, under one of the feales of a ba¬ lance by means of a thread, and, having properly counterpoifed it by weights, put it into the oppofite fcale ; apply the flame of a candle underneath, you will inftantly perceive the cone to arife, and it will not be brought into equilibrium with the other but by a much greater weight than thofe who have never feen the experiment would believe. If we try this experi¬ ment with more accuracy, by getting proper recep¬ tacles made which contain determinate quantities of air, we will find that the pow.er of the heat depends much more on the capacity of the bag which contains it than could well be fuppofed. Thus, let a cubical receptacle be made of a fmall wooden frame covered with paper capable of containing one foot of air, and let the power of a candle be tried with this as above diredled for the paper cone. It will then be found that a certain weight may be raifed; but a much greater one will be raifed by having a receptacle of the fame kind which contains two cubic feet; a ftill greater by one of three feet ; a yet greater by one of four feet, &c. and this even though the very fame candle be made ufe of; nor is. it known to what extent even the power of this fmall flame might be carried. Rarefied- From thefe experiments it appears, that in the aero- air balloons ftatic machines conftrudled on Montgolfier’s'plan, it^®’^^’! c muft be ah advantage to have them as large aspoffible ;|a‘r'e.e ass becaufe poffible. 206 A E R O S T becaufe a fmaller quantity of fire will tfren have a great¬ er effect in railing them, and the danger from that element, which in this kind of machines is chiefly to be 40 dreaded, will be in a great meafure avoided. On this How bal-^ fubjedt it may be remarked, that as the cubical con- rife'by'the tents a globe, or any other figure of which balloons common are made, increafe much more rapidly than their fur- heat of the faces, there muff ultimately be a degree of magni- atmofpfjere. tude at which the imalleft imaginable heat would raife any weight whatever. Thus, fuppofing any aeroftatic machine capable of containing 500 cubic feet, and the air within it to-be only one degree hotter than the ex¬ ternal atmofphere; the tendency of this machine to rife, even without the application of artificial heat, would be near an ounce. Let its capacity be increafed 16 times; and the tendency to arife will be equivalent to a pound, though this may be done without making the machine 16 times heavier than before. It is cer¬ tain, however, that all aeroftatic machines have a ten¬ dency to produce or preferve heat within them, which would by no means be imagined by thofe who have not made the experiment. When Meffrs Charles and Roberts made their longeft aerial voyage of 150 miles, they had the curiofity to try the temperature of the air within their balloon, in comparifon with that of the external atmofphere ; and at this time they found, that, when the external atmofphere was 63°, the ther¬ mometer within the balloon ftood at 104°. Such a dif¬ ference of temperature mull have given a machine of the magnitude which carried them a confiderableafcend- ing power independent of any other caufe, as, it amount¬ ed to 41 grains on every cubic foot; and therefore in a machine containing 50,000 fuch feet would have been almoft 200 pounds. Hence we may eafily ac- count for what happened at Dijon, and is recorded by A'ballot n Mr Morveau. “ A balloon, intended to be filled with at Dijon inflammable air, being completed, was, by way of into the at hUed with common air, and in that ftate ex- jpofpbere, P0fed to the atmofphere. Now it was obferved, and indeed a fimilar obfervation had been made before, that the air within the balloon was much hotter than the circumambient air: the thermometer in the former ftood at I20c; whereas in the latter, even when the fun Ihone upon it, the thermometer ftood at 84°. This ftiowed a confiderable degree of rarefadlion within the balloon; and confequently it was fufpefted, that, by means of this rarefaction alone, efpecially if it were to increafe a little, the balloon might afcend. On the 30th of May, about noon, the wind being rather ftrong, agitated the balloon fo that two men were em¬ ployed to take care of it ; but, notwithftanding all their endeavours, it efcaped from its confinement, and, lifting up about 65 pounds weight of cords, equato¬ rial circle, &c. rofe many feet high, and, palling over fome houfes, west to the diftanee of 250 yards, where at length it was .properly fecured.” Internal This difference between the external and internal beat of the heat being fo very confiderable, muft. have a great in-, balloon* has fllienCe.upon aeroftatic machines, and will undoubtedly enceVn U ^nfluence thofe filled with inflammable air as well as the aerial voy- other kind. Npr is.it unlikely, that the Ihort time ages. which fnany aerial voyagers have been able to continue in the atmofphere, may have been owing to the want of a method of preferving this internal heat. It may flaturally be fuppofed, and indeed it has always been A T I O N. Principles* found, that balloons, in palling through the higher re¬ gions of the atmofphere, acquire a very eonfiderable quantity of moifture, not only from the rain or fnow they fometimes meet with, but even from the dew and vapour which condenfes upon them. On this an eva¬ poration will inftantly take place ; and, as it is the pro¬ perty of this operation to produce a very violent cold, the internal heat of the balloon muft be foon exhaufted in fuch a manner as to make it become fpecifically hea¬ vier than the common atmofphere, and confequently defcend in a much Ihorter time than it would have done by the mere lofs of air. To this, in all probability,. 43 we are to afcribe the defcent of the balloon which car- Great ten- ried Meffrs Blanchard and Jeffries ; and which feemed fo extraordinary to many people, that they were ob- chard>3 ],a|^ liged to have recourfe to an imaginary attraction in ]0on to de- the waters of the ocean in order to folve the pheno-fcend ac- menon. This fuppofition is rejected by Mr Caval-counted^or* lo ; who explains the matter, by remarking, that in two former voyages made with the fame machine, it could not long fupport two men in the atmofphere; fo that we had no occafion to wonder at its weaknefs on this occafion. “ As for its rifing higher (fays he), juft when it got over the land, that may be eafily ac¬ counted for. In the firft place, the two travellers, threw out their clothes juft about that time; fecondly, in confequence of the wind’s then increafing, the bal- kion travelled at a much greater rate than it had done whilft over the fea ; which increafe of velocity leffened its tendency to defcend: befides which, the vicilfitudes of heat and cold may produce a very confiderable ef- feft ; for if we fuppofe, that the air over the land was colder than that over the fea, the balloon coming into the latter from the former, continued to be hotter than the circumambient air for fome time after; and confe¬ quently, it was comparatively much lighter when in the cold air over the land, than when in the hotter air over the fea; hence it floated eafier in the former than . in the latter cafe.” It feems indeed very probable, that there was fome- thirig uncommon in the cafe of Mr Blanchard’s balloon . while palling over the fea ; for, as it rofe higher after reaching the land than in any former period of the voyage, and likewife carried them to the diftance over land more than half of that which they had paffed over water, we can fcarce avoid fuppofing, that it had a tendency to defcend when over the water more than when over land, independent of any lofs of air. Now, it does not appear that the air over the fea is at all warmer than that above land ; on the contrary, there is every reafon to believe, that the fuperior refledtive power of the land renders the atmofphere above it warmer than the fea can do : but it is very natural to fuppofe, that the air above the fea is more moift than that above land ; and confequently, by letting fall its moifture upon the balloon, muft have occafioned an e- vaporation that would deprive the machine of its inter¬ nal heat, v/hich it would partly recover after it entered the warmer and drier atmofphere over land. 44 We lhall now proceed to the conftruclion of aero- Conftrue- ftatic machines ; of which the fmaller are only for a- tion of ae- mufement, or fome flight experiments, and are very ma- eafily made* As in all of them, however, it is of thec 1‘ies* utmoft cohfequence to have the weight as little as pof- fible, the jhape becomes. an objeft of great confidera- tipn, . Pradice. A E R O S 1 45 tion. For this purpofe a fpherical figure has been ma- Gf their thematically demonftrated to be the bell; as capable of * ' containing a greater quantity under a fmaller furface than any other. Thus a perfect fphere cdntains lefs furface in proportion to its folidity than a fpheroid ; a fpheroid lefs than a cylinder; the latter lefs than a cube ; and a cube ftill lefs than a paralklopiped. In all cafes, therefore, where we can fill the whole capa¬ city of the balloon with air equally light, the fpherical figure is undoubtedly to be preferred ; and this holds good with regard to all inflammable air-balloons, whe¬ ther their fize be great or fmall; but in the rarefied air ones, where the under part muft neceflarily be much colder than the upper, the globular fhape feems not fo proper. An inverted cone, or truncated pyramid, with the fmaller part undermoft, feems then to be moft pro¬ per, as it allows the heated air (which has a great ten¬ dency to expand as well as to afcend) to collect in the wide part at the top,, while the ufelefs furface in the lower part, and which, in any other figure, would con¬ tain only the colder and heavier air, is thus thrown afide. In fail it has been found, that aeroftatic ma¬ chines, railed by means of rarefied air, when made of the ihape of a parallelepiped, or even one deviating ftill more from the Ihape of a globe, have anfwered the purpofe as well as they could have been fuppofed to do, had ever fo much care been taken in forming them exaftly to that ftiape. The very firft machine made by Mr Montgolfier was in form of a parallelepiped ; and though it contained only 40 cubic feet, ihowed a very confiderable power of afeent. A very large one, 74 feet high, which Mr Montgolfier had defigned to exhibit before the royal family, had the middle part of it prifmatic for about the height of 25 feet; its top was a pyramid of 29 feet; and its lower part was a truncated cone of near 20 feet. It weighed 1000 pounds; and, notwithftanding its ihape, in a very ftiort time manifefted a power of afeent equal to 500 pounds. Another aeroftatic machine of a fmall fize, but of the figure of a parallelepiped, being fuffered to afcend with 30 iheets of oiled paper fixed in a wire frame, and fet on fire, rofe to a great height, and in 22 mi¬ nutes could not be feen. It feems therefore, that, with regard to the ihape of thefe machines, it is by no means neceflary to adhere rigidly to that of a fphere; but g that any oblong form anfwers very well. Materials. For experimental purpofes, both the inflammable and rarefied air-balloons may be made of paper ; the former being made of that kind called^/tf-/«/?, var- niihed over with linfeed-oil; the latter either of that or any other kind, without varnifh. In order to avoid the danger of burning, however, it has been propofed to impregnate the paper of which thefe fmall rarefied air-balloons are made with folution of fal-ammoniac, alum or fome other fait; but this does not feem to be neceifary. Thpfe filled with inflammable air have been made of gold-beater ikin or peeled bladders ; but the cheaper material of paper is undoubtedly preferable. ■ For aeroftatic machines of ft larger fize, the material Sell; varnifh univerfally employed is varnilhed filk ; and for thofe of for inflam- the rarefied-air kind, linen painted over with fome fize mable-air colour, or lined with paper. The beft varnifh for an cordin^ ^o" inflammable air-balloon is that made with bird-lime, Mr de St ‘ansmetho^* Fond.—“ In order to render linfeed-oil drying, boil it with two ounces of faccharum faturni and three ounces of litharge, for every pint of oil, till the oil has diffolved them, which will be accomplifhed in half an hour; then put a pound of birdlime and half a pint of the drying oil into a pot (iron or copper pots are the fafeft for this purpofe), the capacity of which may be equal to about one gallon, and let it boil very gently over a flow charcoal fire till the birdlime ceafes to crackle, which will be in about half or three quar¬ ters of an hour; then pouf upon it two pints and a half more of drying oil, and let it boil for one hour longer, ftirring it very frequently with an iron or wooden fpatula. As the varnifh, whilft boiling, and efpecially when it is nearly done, fwells very much, care fhould be had to remove, in thofe cafes, the pot from the fire, and to replace it when the varnifh fub- fides, otherwife it will boil over. Whilft the fluff is boiling, the operator fhould, from time to time, ex¬ amine whether the varnifh has boiled enough; which is thus known :—Take fome of it upon the blade of a knife, and then, after rubbing the blade of another knife upon it, feparate the knives ; and when, on this feparation, the varnifh begins to form threads between the two, you may conclude that it is done ; and, withoot lofing time, it muft be removed from the fire. When it is almoft, though not quite, cold, add about an equal quantity of fpirit of turpentine : mix it well together, and let it reft till the next day ; when, having warmed it a little, ftrain and bottle it. If it is too thick, add fome more fpirit of turpentine. When this varnifh is laid upon the filk, the fluff fhould be made perfeftly dry, and ftretched ; fo that the varnifh, which ought to be ufed lukewarm, may fill up the pores of the fluff. The varnifh fhould be laid once very thin upon one fide of the fluff; and, about 12 hpurs after, two other coats of it fhould be laid on, one on each fide ; and, 24 hours after, the filk may be ufed, though, in cold weather, it may be left to dry fome time longer.” Much has been faid in France of their elaftic gum* varnifh, 208 AEROSTATION. Pradice vamifli, and its compofition kept a fecret; but Mr each equal to a quarter of the circumference, fo that Baldwin, after many expenfive trials, declares to the the whole length AE of the pattern may be equal to world what he confiders as the fecret; and it is merely half the circumference. Thirdly, divide AD into 18 this: “Take any quantity of caoutchouc, as two ounces equal parts; and to the points of divifion apply the averdupois ; cut it into fmall bits with a pair of fcif- lines hi, kl, &c. parallel to each other, and perpen- fars; put a ftrong iron ladle (like that ufed by plum- dicular to AD. Fourthly, divide the whole circum- bers) over a common pitcoal or other fire. The fire ference in twice the given number of pieces, and make muft be gentle, glowing, and without fmoke. When DC and BB each equal to the quotient of this divi- the ladle is hot, much below a red heat, put a fingle fion ; fo that the whole, BC, is equal to the greateft bit into the ladle. If black fmoke iffues, it 'will pre- breadth of one of thefe pieces. Fifthly, multiply the fently flame and difappear, or it will evaporate with- above-mentioned quotient by the decimals annexed to out flame: the ladle is then too hot. When the fg, viz. 0.99619, and then the product exprefles the ladle is lefs hot, put in a fecond bit, which will pro- length of fg“, again multiply the fame length of DE duce a •white fmoke. This •white fmoke will continue by the decimals annexed to hi, and the product ex- during the operation, and evaporate the caoutchouc: therefore no time is to be loft; but little bits are to be put in, a few at a time, till the whole are melted. It fjhould be continually and gently ftirred with an iron or brafs fpoon. Two pounds or one quart of the beft drying oil (or of raw linfeed-oil, which, to¬ gether with a few drops of neats-foot oil, has flood a month, or not fo long, on a lump of quicklime, to make it more or lefs drying), is to be put into the melted caoutchouc, and ftirred till hot, and the whole poured into a glazed veffel, through a coarfe gauze or fine fieve. When fettled and clear, which will be in a few minutes, it will be fit for ufe either hot or cold.” Mr Baldwin is not at liberty, he obferves, to publifh the art of laying on the varnifh: but fays, that it con- fifts in making no intejline motion in the varnifh, which would create minute bubbles ; that therefore brufhes are improper. Mr Blanchard’s method of making elaftic- gum varnifh for the filk of a balloon, is the following. “ Diffolve elaftic gum (caoutchouc) cut fmall in five times its weight of fpirit of turpentine, by keeping them feme days together ; then boil one ounce of this folu- tion in eight-ounces of drying linfeed-oil for a few mi¬ nutes ; laftly, ftrain it. It muft be ufed warm.” The pieces of filk for the balloon muft be cut out of a pro¬ per fize, according to the dimenfions, after the varnifh is fufficiently dry. They may be joined by laying about half an inch of the edge of one piece over the edge of the other, and fewing them by a double Hitch¬ ing. Mr Blanchard ufes expeditioufly the following method. He lays about half an inch of the edge of one piece flat over the edge of the other, and pafies a hot iron over it; in doing which a piece of paper ought to be laid both under and over the filk. The joining may be rendered more fecure by running it with a filk thread, and flicking a ribband over it. The ribbands laid over feams may be ftuck with common glue, provided the varnifh of the filk is properly dried. When the glue is quite dry, the ribbands fhould be varnifhed over, to prevent their being unglued by the ^ rain. Of cutting The beft method of cutting the pieces of filk that are tic gores to form a balloon, is to deferibe a pattern of wood or ftiff for a gli-be. card.paper, and then to cut the filk upon it. As the edges of fuch a pattern are not perfect circles, they cannot be deferibed by a pair of compaffes : but the ad Plate ILbeft method of drawing them is as follows. Firft, draw, fig- 5- on a flat furface two right lines AE and BC, per¬ pendicular to each other. Secondly, Jind the circum¬ ference anfwering to the given diameter of the balloon in feet and decimals of a foot; and make AD and DE 6. ' 3 preffes the length of hi; and, in fhort, the product arifing from the multiplication of the length of DC by the decimals annexed to each of the parallel lines; gives the length of that line. Laftly, having found the lengths of all thefe lines, draw by hand a curve¬ line palling through all the extremities of the faid lines, and that is the edge of one quarter of the pat¬ tern. The other quarters may be eafily deferibed, by. applying to them a piece of paper cut according to that already found;—Suppofe, for example, that the diameter of the balloon to be conftructed is 20 feet, and that it is required to make it of 12 pieces: then, in order to draw the pattern for thofe pieces, find the circumference of the balloon, which is 62.83 feet, and, dividing it by four, the quotient is 15.7 feet; make therefore AD equal to 15.7 feet, and DE likewife of the fame length. Divide the circumference 62.83 hy 2£, which is double the number of pieces that are to form the balloon, and the quotient, 2.618 feet, is the length of DC and likewife of BD ; fo that BC is equal to 5.236 feet. Then,, having divided the line AD into 18 equal parts, and having drawn the paral¬ lel lines from thofe points of divifion, find the length of each of thofe lines by multiplying 2.618 by the de¬ cimals annexed to that line; Thus,. 2.618, multiplied by 0.99619, gives 2.608 feet for the length of Jg; and again, multiplying 2.618 by 0.98481, gives 2.578 feet for the length of hi; and fo of the reft.—In cut¬ ting the pieces after fuch a pattern, care fhould be taken to leave them about three quarters of an inch all round larger than the pattern, which will be taken up by the feams. To the upper part of the balloon there ftiould be adapted, and well fitted in, a valve opening inwards ; to which fhould be faftened a firing pafling through a hole made in a fmall piece of round wood fixed in the loweft part of the balloon oppofite to the valve, the end of this, firing faftened in the car below, fo that the aeronaut may open the valve when occafion requires. The adlion of this valve may be underftood from fig. 3. A round brafs plate AB has a round hole CD,, about' two or three inches diameter, covered on both fides with ftrong fmooth leather. On the infide there is a fhutter E, alfo of brafs, covered with leather, which is to clofe the hole CD ; being about two inches larger in diameter than the hole. It is faftened to the lea¬ ther of the plate AB ; and by a fpring, which need not be very flrong, it is kept againft the hole. The elafticity of the gas itfelf will help to keep it fhut. To this fhutter the firing is faftened, by which it is occafionally opened for the efcape of gas. A fmall firing Seriate i: Acorsi'ics. Aerostation. /3. 'Practice. A EROSTATION. ft ring or other fecurity fhould be fixed to the ftiutter and the plate, fo as not to admit the fhutter to be opened beyond a certain fafe diftanee. To the lower part of the balloon two pipes ftiould be fixed, made of the fame ftuff as the envelope ; 6 inches diameter for a balloon of 30 feet, and proportionally larger for bal¬ loons of a greater capacity. They muft be long enough for the car. For balloons of 18 feet and lefs diame¬ ter, one neck or pipe will be fufficient. Thefe pipes are the apertures through which the inflammable gas is introduced'into the balloon. The car or boat is belt made of wicker-work, cover¬ ed with leather, and well painted or varniflied over; and the proper method of fufpending it, is by ropes pro¬ ceeding from the net which goes over the balloon. This net fliould be formed to the fhape of the balloon, and fall dewn to the middle of it, with various cords proceeding from it to the circumference of a circle about two feet below the balloon; and from that circle other ropes fhould go to the edge of the boat. This circle may be made of wood, or of feve- ral pieces of flender cane bound together. The mefhes of the net may be fmall at top, againft which part of the balloon the inflammable air exerts the greateft force; and increafe in fize as they recede from the top. A hoop has fometimes been applied round the middle of the balloon to faften the net. This, though not abfolutely neceflary, is beft made of pieces of cane bound together, and covered with leather. With regard to the rarefied-air machines, Mr Ca- vallo recommends firft to foak the cloth in a folution of fal ammoniac and common fize, ufing one pound of each to every gallon of water ; and when the cloth is quite *dry, to paint it over in the infide with fome earthy colour, and ftrong fize'or glue. When this paint has dried perfettly, it will then be proper to varnifli it.with oily varniih, which might dry before it could penetrate quite through the cloth. Simple dry¬ ing linfeed oil will anfwer the purpofe as well as any, provided it be not very fluid. Of fiffing ^ now only remains to give fome account of the aeroftatic method by which aeroftatic machines may be filled machines, with their proper gas, in order to give them their power of afeending into the atmofphere ; and here we are enabled to determine with much greater precifion concerning the inflammable-air balloons than the others. Methods of With regard to them, a primary confideration is, the procuring moft proper method of procuring the inflammable air. inflamma- Jt may be obtained in various ways, as has been fhown ble air.. under the article Aerology : But the moft advanta¬ geous methods are, by applying acids to certain metals; by expofing animal, vegetable, and fome mineral fub- ftances, in a- clofe vdfel to a ftrong fire ; or by tranf- mitting the vapour of certain fluids through fed-hot tubes. 1. In the firft of thefe methods, iron, zinc, and vitriolic acid, are the materials moft generally ufed. The vitriolic acid muft be diluted by five or fix parts of water. Iron may be expefted to yield in the com¬ mon way 1700 times its own bulk of gas 5 or one cubic foot of inflammable air to be produced by 4! ounces of iron, the like weight of oil of vitriol, and 2z\ oun¬ ces of water. Six ounces of zinc, an equal weight of oil of vitriol, and 30 ounces of water, are neceffary for producing the fame quantity of gas. It is more Vol. I. Part I. proper to ufe the turnings or chippings of great pieces of iron, as of cannon, See. than the filings of that metal, becaufe the heat attending the effervefcence will be diminifhed 5 and the diluted acid will pafs more readily through the interftices of the turnings when they are heaped together, than through the filings, which ftick clofer to one another. The weight of the inflammable air thus obtained by means of acid of vi¬ triol, is, in the common way of procuring it, gene¬ rally one feventh part of the weight of common air; but with the neceffary precautions for philofophical experiments, lefs than one-tenth of the weight of common air. Two other forts .of elaftic fluids are fometimes generated with the inflammable air. Thefe may be feparated from it by paffing the inflammable air through water in which quicklime has been diffol- ved. The water will abforb thefe fluids, cool the in¬ flammable air, and prevent its over-heating the bal¬ loon when introduced into it. Fig. 7. of 2d Plate II. reprefents an apparatus de- feribed by Mr Cavallo as proper for filling balloons of the fize of two or three feet in diameter with inflam¬ mable air, after paffing it through water.—A is the bottle with the ingredients ; BCD a tube fattened in the neck at B, and paffing through C, the cork of the other bottle, in which there is another hole made to re¬ ceive the tube on which the balloon is tied. Thus it is plain, that the inflammable air coming out of the tube D will pafs firft through the water of the bottle E and then into the balloon. Two fmall calks may be ufed inftead of the bottles A and E. 2. Inflammable air may be obtained at a much cheaper rate by the action of fire on various fubftances; but the gas which thefe yield is not fo light as that produced by the effervefcence of acids and metals. The fubftances proper to be ufed in this way are, pit-coal, afphaltum, amber, rock-oil, and other minerals; wood, and efpecially oak, camphor-oil, fpirits of wine, ether, and animal fubftances, which yield air in different de- .grees, and of various fpecific gravities 5 but pit-coal is the preferable fubftance. A pound of this expofed to a red heat, yields about three cubic feet of inflammable air, which, whether it be paffed through water or not, weighs about one-fourth of the weight of common air. Dr Prieftley found, as we have elfewhere noticed, that animal or vegetable fubftances will yield fix or feven times more inflammable air when the fire is fuddenly increafed than when it is gently raifed, though it be afterwards made very ftrong. Mr Cavallo obferves, that the various fubftances above enumerated generally yield all their inflammable air in about one hour’s time. The general method is, to inclofe the fubftances in iron or earthen veffels, and thus expofe them to a ftrong fire fufficient to make the veffels red-hot: the inflam¬ mable air proceeding from the aperture of the veffel is received into a tube or refrigeratory, and,paffingthrough thebube or worm, is at laft collected in a balloon or other veffel. A gun-barrel has often been ufed for ef- fays of this kind. The fubftance is put into it fo as to fill fix or eight inches of its loweft part, the re¬ mainder filled with dry fand: a tube, adapted to the mouth of the barrel, is brought into a bafin of water under an inverted receiver; and the part of the barrel containing the fubftance being put into the fire and made red-hot, the inflammable air is col- D d le&ed 209 AEROSTATION. Praftice. lefted in the inverted receiver. As the gun-barrel can¬ not ferve for producing a large quantity of inflammable air, Mr Cavallo recommends, as the moft advantageous fhape, the following contrivance :—Let the veffel be made of clay, or rather of iron, in the (hape of a Flo¬ rence flafk, fomewhat larger, and whofe neck is longer and larger (See ABC, fig. 8.) Put the fubftance to be ufed Into this veffel, fo as to fill about four-fifths or lefs of its cavity AB. If the fubflance is of fuch a nature as to fwell much by the aftion of the fire, lute a tube of brafs, or firft a brafs and then a leaden tube, to the neck C of the veffel; and let the end D of the tube be fliaped as in the figure, fo that going into the iter of a tube HI, it may terminate under a fort ol ' erted vef¬ fel EF, to the upper aperture of which the balloon G is adapted. Things thus prepared, if the part AB of the veffel is put into the fire, and made red-hot, the in¬ flammable air produced will come out of the tube CD, and palling through the water will at laft enter into the balloon G. Previous to the operation, as. a confider- able quantity of common air remains in the inverted veffel EF, which it is more proper to expel, the veffel EF Ihould have a ftop-cock K, through which the common air may be fucked out, and the water afcend as high as the ftop-cock. The dimenfions of fuch an apparatus Mr Cavallo gives thus : Diameter of largeft part of the veffel ABC feven inches, length of whole veffel 16 inches; diameter of its aperture one inch, dia¬ meter of the cavity of tube CD three-fourths of an inch; lower aperture of the veffel EF fix inches, leaft height of the veffel EF 24 inches; its aperture F about two inches. The aperture of the veffel EF Ihould be at leaft one foot below the furface of the water in HI. Care muft be taken that the fire ufed in this procefs be at a fufficient diftance, otherwife it may happen to fire the inflammable air which may efcape out of the veffel EF. 3. The laft method of obtaining inflammable air was lately difcovered by Mr Lavoifier, and alfo by Dr. Prieftley. Mr Lavoifier made the fteam of boiling wa¬ ter pafs through the barrel of a gun, kept red-hot by burning coals. Dr Prieftley ufes, inftead of the gun- barrel, a tube of red-hot brafs, upon which the fteam of water has no effeft, and which he fills with the pieces of iron which are feparated in the boring of can¬ non. By this method he obtains an inflammable air, the fpecific gravity of which is to that of common air as 1 to 13. In this method, not yet indeed reduced to general practice, a tube, about three quarters of an inch in diameter, and about three feet long, is filled with iron turnings; then the neck of a retort, or clofe boiler, is luted to one of its ends, and the worm of a refrigeratory is adapted to its other extremity. The middle part of the tube is then furrounded with burn¬ ing coals, fo as to keep about one foot in length of it red-hot, and a fire is always made under the retort or boiler fufficient to make the water boil with vehemence. In this procefs a confiderable quantity of inflammable air comes out of the worm of the refrigeratory. It is faid that iron yields one half more air by this means than by the action of vitriolic acid. For filling large balloons, a greater apparatus is ne- ceffary ; and the only materials that can, with any cer¬ tainty of fuccefs, be employed for producing the pro¬ per gas, are, oil of vitriol, and iron filings or turnings^ It has indeed been recommended to ufe zinc inftead of iron filings, becaufe white vitriol, the fait produced by the union of the vitriolic acid and zinc, is much more valuable than the green fort produced by the u- nion of the fame acid with iron. But though this is undoubtedly the cafe, it will as certainly be found, up¬ on trial, that the fuperior price of the zinc will be more than an equivalent for all the advantage that can be derived from the additional price of the white vitriol. ^ For a balloon of 30 feet diameter, Mr Cavallo vecom- jyrr Caval- mends 3900 pounds of iron turnings, as much oil ofio’sreceqst.l vitriol, and 19,500 pc.—ds of w^ater. Thefe pro¬ portions, however, appear too great with refpeft to the acid and metal, and too little with refpeft to the water. Oil of vitriol will not exert its power upon iron unlefs it be diluted with five or fix times its quan¬ tity of water; in which cafe, a much fmaller quantity of both acid and metal will ferve. Mr Lunardi, who jvjr Hinar-j from the number of his voyages had certainly much di’smethod, praftical knowledge in aeroftation, filled his balloon at Edinburgh and Glafgow with about 2000 pounds of iron (the borings of cannon procured from Carron), as much vitriolic acid, and 12,coo pounds of water. The iron was placed in his veffels in layers, with ftraw between them, in order to increafe the furface. His apparatus was not materially different from that of Mr Cavallo, reprefented bottom of Plate I. fig. 2. where AA are two tubs, about three. feet in diameter and nearly two feet deep, inverted in large tubs EiB filled with water. In the bottom of each of the inverted tubs a hole is made, and a tube E of tin adapted, which is about feven inches in diameter, and feven or eight long. To thefe tubes the filken ones of the balloon are to be tied. Round each of the tubs B, five, fix, or more ftrong calks are placed; in the top of each two holes are made, and to one of thefe holes a tin tube is adapted, and fo fhaped, that, palling over the edge of the tub B, and through the w^ater, it may ter¬ minate with its aperture under the inverted tub A. The other hole of thefe calks ferves for the introduc¬ tion of materials, and is flopped with a wooden plug. When the balloon is to be filled, put the net over it, and let it be fufpended as ffiowm by CDF; and having expelled all the common air from it, let the filken tubes be faftened round the tin ones EE ; and the materials being put into the calks, the inflammable air, palling into the balloon, will foon diftend, and render it ca¬ pable of fupporting itfelf; after which the rope GH may be flipped off. As the balloon continues to be filled, the net is adjufted properly round it; the cords that furround it are faftened to the hoop MN ; then the boat IK being placed between the two fets of cafks, is faftened to the hoop MN, and every thing that is required to be fent up, as ballaft, inftruments, &c. is placed in it. At laft, when the balloon is little more than three quarters full, the filken tubes are fe¬ parated from the tin ones of the inverted tubs, and their extremities being tied up, are placed in the boat. Laftly, the aeronauts being feated in the-boat, the la-, teral ropes are flipped off, and the machine is abando • ned to the air. (See Blanchard's -balloon, Plate II.) This apparatus was at laft reduced by Mr Lunardi to its utmoft fimplicity, by ufing only tw'o large calks, , and fuffering the vapour to go into the balloon with- ' out paging through water. Thua his balloon was filled iPradHce. A E R O S T in lefs than half an hour, when, before, it had requi¬ red two hours at leaft. The finking of his cafks in the ground was alfo an additional convenience, as it created no confufion, and rendered the materials much more eafily conveyed into them. With regard to the rarefied-air balloons, the method r of filling them is as follows. A fcaffold ABCD, the I'Of filling I rarefied-a' | balloons. A T I O N. fcending, and difcharge of the ballaft for afcending, will by degrees render the machine incapable of float¬ ing ; for hr the air it is impoffible to fupply the lofs of ballaft, and very difficult to fupply that of inflammable air. Thefe balloons will alfo rife or fall by means of the rarefaction or condenfation of the inclofed air, oc- cafioned by heat and cold. It has been propofed to breadth of which is at leaft two-thirds of the diameter pf aid a balloon in its alternate motion of afcent and de- the machine, is elevated about fix or eight feet above the ground. From the middle of it defcends a well E, rifing about two or three feet above it, and reaching to the ground, furnifhed with a door or two, through which the fire in the well is fupplied with fuel. The well fhould be conftruCted of brick or of plaftered wood, fcent, by annexing tp it a veffel of common air, which might be condenfed for lowering the machine, and ra¬ refied again, by expelling part of it, for raifing the machine: But a veflel adapted to this purpofe muft be very ftrong; and, after all, the affiftance afforded by it would not be very confiderable. ,M. Meunier, in Gr¬ and its diameter fhould be fomewhat lefs than 'that of der to attain this end, propofes to inclofe one balloon the machine. On each fide of the fcaffold are. erefted filled with common air in another filled with inflam- two mafts HI, KL, each of which has a pulley at the top, and .rendered firm by means of ropes KG, KP, HP, PIG. The machine to be filled is to be placed mable air: as the balloon afcends, the inflammable air is dilated, and of courfe compreffes the internal balloon containing the common air; and by diminiihing its on the fcaffold, with its neck round the aperture of quantity, leffens its weight. If it ftiould be neceffary the well. The rope palling over the pullies of the two mafts, ferves, by pulling its two ends, to lift the balloon about 15 feet or more above the fcaffold ; and the reft of the machine is reprefented by the dotted lines in the figure MNO. The machine is kept fteady, and held down, whilft filling, by ropes palling through loops or holes about its equator; and thefe ropes may eafily be di^ngaged from the machine, by flipping them through the loops when it is able to fuftain it- felf. The proper combuftibles to be lighted in the to fupply this lofs, he fays it may be eafily done by a pair of bellows fixed in the gallery. Others have pro- pofed to annex a fmall machine with rarefied air to an inflammable-air balloon by ropes, at fuch a diftance that the fire of the former might not affeft the inflammable air of the latter: the whole apparatus, thus combined, of balloons formed on the two principles of heated and inflammable air, might be raifed or lowered by merely increafing or diminifhing the fire in the lower balloon. Wings or oars are the only means of this fort that have well, are thofe which burn quick and clear, rather than been ufed with fome fuccefs; and, as Mr Cavallo ob- fuch as produce much fmoke ; becaufe it is hot air, ferves, they feem to be capable of confiderable improve- and not fmoke, that is required to be introduced into ment. Although great effedls are not to be expected the machine. Small wood and ftraw have been found from them, when the machine goes at a great fate, the to be very fit for this purpofe. Mr Cavallo obferves, as beft methods of moving thofe wings are by the hu¬ man ftrength applied fimilarly to the oars of a water¬ man. They may be made in general of filk ftretched between wires, tubes, or flicks ; and when ufed, mull be turned edgewife when they are moved in the direc¬ tion in which the machine is intended to be impelled, but flat in the oppofite direftion.

As the current of h°t air afcends, the machine will foon dilate, and lift itfelf above the fcaffold and gallery which was covered by it. The paffengers, fuel, inftru- ments, &c. are then placed in the gallery. When the is the reprefentation of one of Mr Blanchard’s wings, machine makes efforts to afcend, its aperture muft be Fig. 10. is one of thofe ufed by Mr Lunardi, brought, by means of the ropes annexed to it, towards which confifts of many filk fhutters or valves, ABCD, the fide of the well a little above the fcaffold ; the fire¬ place is then fufpended in it, the fire lighted in the DECF, &c. every one of which opens on one fide only, viz.

(See Montgolfier'’s bal- ' loon, Plate II.) It has been determined by accurate ex¬ periments, that only one-third of the common air can be expelled from thefe large machines ; .and therefore conltruftion, this fort of oars do not need being turn¬ ed edgewife.

Mr Le Clerc has given a Latin tranflation of them, with'notes, and feveral differtations intitled Sylva Pbilologica. jESCHYLUS, the tragic poet, was born at Athens. Authors differ in regard to the time of his birth, fome placing it in the 65th, others in the 70th Olympiad; but according to Stanley, who relies on the Arunde- lian marbles, he was born in the 63d Olympiad. He was the fon of Euphorion, and brother to Cynegirus and Aminias, who diftinguiftied themfelves in the battle of Marathon, and the fea-fight of Salamis, at which en¬ gagements jEfchylus was likewife -wefent. In this laft aftion, according to Diodorus Siculus, Aminias, the younger of the three brothers, commanded a fquadronr of (hips, and behaved with fo much conducl and bra¬ very, that he funk the admiral of the PerSin fleet, and- fignalized himfelf above all the Athenians. To this brother our poet Was, upon a particular occafion, obli¬ ged for faving his life : ./Elian relates, that zEfchylus being charged by the Athenians with certain blafphe- mous expreffions in fome of his pieces, was accufed of impiety, and condemned to be ftoned to death : they were juft going to put the fentence in execution, when Aminias, with a happy prefence of mind, throwing afide his cloak, fliowed his arm without a hand, which he had loft at the battle of Salamis in defence of his country. This fight made fuch an impreffion on the judges, that,, touched with the remembrance of his valour, and with the friendftiip he (bowed for his brother, they pardoned jEfchylus. Our poet, however, refented the indignity of this profecution, and refolved to leave a place where his life had been in danger. He became more deter¬ mined in this refolution when he found his pieces lefs pleafing to the Athenians than thofe of Sophocles, tho’ a much younger writer. Some affirm, that iEfchylus ne¬ ver fat down to compofe butwhen he had drank liberally- He wrote a great number of tragedies, of which there are but feven remaining; and notwithftanding the (harp. cenfures of fome critics, he muft be allowed to have been the father of the tragic art. In the time of Thefpis,, there was no public theatre to aft upon ; the ftrollers. driving about from place to place in a cart. ^Efchylus furnifhed his aftorS with malks, and dreffed them fuitably to their charafters. He likewife introduced the • buflein, to make them appear more like heroes.—The ancients gave JEfchylus alfo the praife of having been the firft who removed murders and (hocking fights from, the eyes of the fpeftators. He is faid likewife to have leffened the number of the chorus. M. Le Fevre has obferved, that iEfchylus never reprefented women in love in his tragedies; which, he fays, was not fuited to his genius; but, in reprefenting a woman tranfported with fur)’, he was Incomparable. Longius fays, that JEfchylue JE S C [2 Jifchyno- jEfchylus has a noble boldnefs of expreffion; and that —-ne- . his imagination is lofty and heroic. It muft be owned, v however, that he affedbed pompous words, and that his fenfe is too often obfcured by figures : this gave Sal- mafius occafion to fay, that he was more difficult to b.e underftood than the fcripture itfelf. But notwith- ftanding thefe imperfeftions, this poet was held in great veneration by the Athenians, who made a public de¬ cree that his tragedies ffiould be played after his death. He was killed in the 69th year of his age, by an eagle letting fall a tortoife 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 Ge- la ; and the tragedians of the country performed plays and theatrical exercifes at his tomb. —The belt edition of his plays is that of London, 1663, fob with a La¬ tin tranflation and a learned commentary by Thomas Stanly. jESCHYNOMENE, Bastard sensitive-plant: • A genus of the decandria order, belonging to the dia- delphia clafs of plants ; the characters of which are r The'cafyx is a one-leav’d eampanulated bilabiated pe- rianthiurn ; the lips equal, but the fuperior one two- cleft, the inferior tridentate.

According to Cicero, there were three deities of this name : the firft, the fon of Apollo, worffiipped in Arcadia, who invented the probe, and bandages for wounds; the fecond, the brother of Mercury, killed by lightning; and the third, the fon of Arifippus and Arfinoe, who firft: taught the art of tooth-drawing and purging. At Epidaurus, AEfculapius’s ftatue was of gold and ivory', with a long beard, his head fur- rounded with rays, holding in one hand a knotty flick, and the other entwined with a ferpent; he was feated - on a throne of tire fame materials as his ftatue, and had a dog lying at his feet. The'Romans crowned him with laurel, to reprefent his defeent from Apollo ; and the Phaliafins reprefented him as beardlefs. The cock, the raven, and the goat, were facred to this deity. His chief temples were at Pergamus, Smyrna, Trica a ci¬ ty in Ionia, and the ifle of Coos ; in all which, votive tablets were hung up, ffiowing the difeafes cured by his afliftance. But his moft famous ftirine was at Epidau¬ rus ; where, every five years, games were inftituted to him, nine days after the Ifthmian games at Corinth. aESCULUS, the Horse-chestnut": Agenu'sof the monogynia order, belonging to the heptandria clafs of plants;; and ranking, in the natural method, under the 39th order, Trihilata.—The characters are : The calyx is a fmall, fingle-leaved, bellied perianthium, divided into five fegments.j The corolla (except in the pavia, where it is four-petal’d and clofe) confifts of five roundith, flat, expanding petals, unequally co¬ loured, and with narrow claws inferted into the calyx. The fiamina have feven fubulated declining filaments, the length of the corolla; the antherse afeending. The pijlillum is a roundiffi germen, ending in a fubulated ftylus; the ftigma pointed. , The pericarpium is a leathery, roundiffi, trilocular, three-valved capfule, The feeds are two, and fubglobular.—In this genus Van Rozen and Miller obferve both male and herma¬ phrodite flowers. There are two Species. \. The hippocaftanum, or common horfe- chefthut. It was brought from the northern parts of Afia about the year 1550, and fent to Vienna about 1588. This tree makes a 1 noble appearance all the month of May, the extremities of the branches being terminated by fine fpikes of flowers fpotted with rofe colours, fo that the whole tree feems covered with them, It is quick in its growth ; fo that in a few years it ar¬ rives at a fize large enough to afford a good (hade in famine r. j£SC [214] iESC ^5fculus. fummer, as alfo to produce plenty of flowers. They ‘-“‘"'i'"" have, however, this great inconvenience, that their wood is of no ufe, being unfit even for burning ; and their leaves beginning to fall in July, foon deprive the trees of their beauty. There is fomething very fingu- lar in the growth' of thefe trees; which is, that the whole (hoot is performed in lefs than three weeks after the buds are opened.—The .nuts are reckoned good food for horfes. In Turkey, they are ground, and mixed with the provender of thefe animals, efpecially thofe which are troubled with coughs or broken-wind- ed. Deer are alfo very fond of the fruit; and at the time of their ripening keep much about the trees, but efpecialiy, in ftrong winds, when the nuts are blown down, which they carefully watch, and greedily de¬ vour as they fall. 2. The pavia, or fcarlet-flowering horfe-cheftnut, a native of Carolina, the Brafils, and the Eall. It grows to about fifteen or fixteen feet high; and there is a delicacy in this tree that makes it definable. The bark of the young (hoots is quite fmooth, and the growing (hoots in fiimmer are of a reddifli hue. The leaves are palmated, being pretty much like thofe of the horfe-chefnut, only much (mailer, and the indentures at the edges are deeper and more acute. The lobes of which they are compofed are fpear-lhaped; they are five in number, are united at their bafe, and (land on a long red footftalk. The leaves grow oppo- fite by pairs on the branches, which are fpread abroad on every fide. The flowers come out from the ends of the branches. The firft appearance of the buds is in May ; though they will not be in full blow till the middle of June. They are of a bright red colour, and confequently have a pleafing effect among the vaft tribe of yellow-flowering forts which (how themfelves in bloom at that feafon. They continue in fuccefiion for upwards of fix weeks; and fometimes are fucceeded by ripe feeds in our gardens. Propagation and culture. The firfl; fpecies is pro¬ pagated from the nuts. In autumn, therefore, when they' fall, a fuflicient quantity (hould be gathered. Thefe (hould be fown foon afterwards in drills, about two inches afunder. If the nuts are kept till fpring, • many of them will be faulty ; but where the femin ary- ground cannot be got ready before, and they' are kept fo long, it may be proper to put them in water, to try their goodnefs. The good nuts will fink, whilft thofe which are faulty will fwim; fo that by proving them this way you may be fure of good nuts, and have more promifing hopes of a crop. In the fpring the plants will come up ; and when they have flood one year, they may be taken up, their tap-roots (hortened, and afterwards planted in the nurfery. When they are of fuflicient fize to be planted -out finally, they muft be taken out of the nurfery with care, the great fide-ihoots and the bruifed parts of the roots (hould be taken off, and then planted in large holes level with the furface of the ground, at the top of their roots; the fibres be¬ ing all fpread and lapped in the fine mold, and the turf alfo worked to the bottom. A flake (hould be placed to keep them fafe from the winds; and they 4 muft be fenced from the cattle till they are of a fuffi- cient fize to defend themfelves. The bed feafon for all this work is O&ober. After the trees are planted, sreither knife nor hatchet (hould come near them; but • they (hould be left to Nature to form their beautiful -Sfculus parabolic heads, and affiime their utmoft beauty.—The horfe-chefnut, like moft other trees, delights moft in good fat land ; but it will grow exceedingly well on clayey and marley grounds. Miller fays, “ When thefe trees are tranfplanted, their roots (hould be preferved as entire as poffible, for they do not fucceed well when torn or cut: nor (hould any of the branches be (hortened, for there is fcarce any tree that will not bear amputation better than this; fo that when any branches are by accident broken, they (liquid be cut off clofe to the Item, that the wound may heal over.” The fecond fpecies is propagated, i. By budding it upon the young plants of the horfe-chefnut. Thefe flocks (hould be raifed as was directed in that article. They (hould be planted in the nurfery way, one foot afunder, and two feet diftant in the rows, which (hould be kept clean of weeds, and muft be dug be¬ tween every winter till the operation is to be pterform- ed. After they have flood in the nurfery-ground about two years, and have made at lead one good fummer’s (hoot, the fummer following is the time for the operation. Then, having your cuttings ready foon after midfummer, the evenings and cloudy weather (hould be made choice of for the work. Whoever has a great number of trees to inoculate, muft regard ho weather, but keep working on, to get his bnfinefs over before the feafon ends ; and, indeed, a good hand will be always pretty fure of fuccefs be the weather what it will. If the flocks were healthy, the fummer fol¬ lowing they will make pretty good (hoots; and in a year or two after that will flower. This is one me¬ thod of propagating this tree; and thofe plants that are propagated this way will grow' to a larger fize than thofe raifed immediately from feeds.—2. This tree alfo may be propagated by feeds; wbich will fome¬ times ripen with us, and may be obtained out of our own gardens. The manner of raifing them this way is as follows: Let a warm border be prepared ; and if it is not naturally fandy, let drift-fand be mixed with the foil; and in this border let the feeds be fown in the month of March, about half an inch deep. After this, conftant weeding muft be obferved; and when the plants are come up, if they could be (haded in the heat of the day, it would be much better. Thefe, with now and then a gentle watering in a dry feafon, w’ill be all the precautions they will require the firft; fummer. The winter following, if the fituation is not extremely well fheltered, protedtion muft be given them from the hard black frofts, which will otherwife often deftroy them ; fo that it will be the fafeft way to have the bed hooped, to cover them wfith mats in fuch weather, if the fituation is not well defended: if it is, this trouble may be faved; for, even wdien young, they are tolerably hardy. In about twro or three years they may be removed into the nurfery, or planted where they are to remain, and they will flower in three - or four years after. The ufual nurfery-care muft be taken of them when planted in that way; and the bed time for planting them there, or where they are. to re¬ main, is October ; though they will grow exceeding well if removed in any of the winter months ; but, if planted late in the fpring, they will require more watering, as the ground will not be fo regularly fettled SO [ 2 as if they had been planted ear- JE fettled to the roots ' lier. ^diSOP, the Phrygian, lived in the time of Solon, about the 50th Olympiad, under the reign of Croefus the laft king of Lydia. As to genius and abilities, he was greatly indebted tp nature ; but in other refpefts not fo fortunate, being born a Have and extremely de¬ formed. St Jerom, fpeaking of him, fays he was un¬ fortunate in his birth, condition in life, and death; hinting thereby at his deformity, fervile Hate, and tragical end. His great genius, however, enabled him to fupport his misfortunes; and in order to alleviate the hardlhips of fervitude, he compofed thofe entertaining and inftrudtive fables which have acquired him fo much reputation. He is generally fuppofed to have been the inventor of that kind of writing; but this is contefted by feveral, particularly Quintilian, who feems to think that Hefiod was the firft author of fables, -difop, how¬ ever, certainly improved this art to a very great degree; and hence it is that he has been recounted the'author of this fort of produ&ions : JEfopus auftor quam materam reperit, Hanc ego poltivi verfibus fenariis. P/W Prol. ad. lib. i. If any thoughts in-thefe iambics f ine, Th’ invention’s iEfop’s, and the verfe is mine.” The firft matter whom rEfop ferved, was one Cara- fius Demarchus, an inhabitant of Athens; and there in all probability he acquired his purity in the Greek tongue. After him he had feveral mafters; and at length came under a philofopher named Idmon or ladmon, who enfranchifed him. After he had recovered his liberty, he foon acquired a great reputation amongft the Greeks; fo that, according to Meziriac, the report of his wif- dom having reached Crcefus, he fent to inquire after him, and engaged him in his fervice. He travelled through Greece, according to the fame author; whe¬ ther for his own pleafure, or upon the affairs of Croefus, is uncertain; and pafiing by Athens foon. after Pifi- ftratus had ufurped the fovereign 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 ufe of by iEfcp are cer¬ tainly very happy inventions to inftrudt, mankind; they poffefs all that is neceffary to perfeft a precept, having a mixture of the ufeful with the agreeable. “ At fop the fabulift (fays Aulus Gellius) was defervedly e- fteemed wife, fince he did not, after the manner of the philofophers, rigidly and imperioufly dictate fuch things as were proper to be advifed and perfuaded ; but, fra-' ming entertaining and agreeable apologues, he thereby charms and captivates the human mind.”—At fop was put to death at Delphi. Plutarch tells us, that he came there with a great quantity of gold and filver, being ordered by Croefus to offer a facrifice to Apollo, and to give a confiderable fum to each inhabitant: but a quarrel arifing betwixt him and the Delphians, he fent back the money to Crcefus; for he thought thofe for whom the prince defigned it, had rendered themfelves unworthy of it. The inhabitants of Delphi contrived an accufation of facrilege againft him; and pretending they had convifted him, threw him headlong from a rock. For this cruelty and injuftice, we are told they were vifited with famine and peftilence; and confulting the oracle, they received for anfwer, that the god de- 15 ] JE T H figned this as a puniftiment for their treatment of rFfop: -®fop they endeavoured to make an atonement, by raifing a pyramid to his honour. . " A2SOP (Clodius), a celebrated adtor, who flourifhed about the 670th year of Rome. He and Rofcius were cotemporaries, and the beft performers who ever appear¬ ed upon the Roman ftage, the former excelling in tra¬ gedy, the latter in comedy. Cicero put himfelf under their diredtion to perfedt his adtion. Alfop lived in a moft expenfive manner, and at one entertainment is faid to have had a dilh which coft above eight hundred pounds; this dilh, we are told, was filled with finging and fpeaking birds, fame of which coft near 50/. The delight which Aifop took in this fart of birds proceed¬ ed, as Mr Bayle obferves; from the expence. He did not make a difh of them becaufe they could fpeak, ac¬ cording to the refinement of Pliny upon this circum- ftance, this motive being only by accident; but becaufe of their extraordinary price. If there had been any birds that could not fpeak, and yet more fcarce and dear than thefe, he would have procured fuch for his table. ALfop’s fan was no lefs luxurious than his fa¬ ther, for he diffolved pearls for his guefts to fwallow. Some fpeak of this as a common pra&ice of his; but others mention his falling into this excefs only on a particular day, when he was treating his friends.

See Fire. The philofophers cannot conceive that the largefb part of the creation fhould be perfe£Uy void; and there* fore they fill it with a fpecies of matter under the de¬ nomination of aiher. But they vary extremely as to the nature and charafter of this aether. Some conceive it as a body_/«/ generis, appointed only to fill up the vacuities between the heavenly bodies; and therefore confined to the regions above our atmofpherc. Others fuppofe it of fo fubtile and penetrating a nature, as to pervade the air, and other bodies, and poflefs the pores and intervals thereof. Others deny the exiftence of any fuch fpecific matter ; and think the air itfelf, by that immenfe tenuity and expanfion it is found capable of, may diffufe itfelf through the interilellar fpaces, and be the only matter found therein. In effeft, aether, being'no objeft of our fenfe, but the mere work of imagination, brought only upon the if age for the fake of hypothefis, or to folve fome phe¬ nomenon, real or imaginary ; authors take the liberty to modify it how they pleafe. Some fuppofe it of an elementary nature, like other bodies ; and only diilin- guiflied by its tenuity, and the other affeftions confe- quent thereon : which is the philofophical aether. O- thers will have it of another fpecies, and not elemen¬ tary ; but rather a fort of fifth element, of a purer, more refined, and fpirituous nature, than the fubltances about our earth: and void of the-common afledtions thereof, as gravity, &e. The heavenly fpaces being the fuppofed region or refidence of a more exalted clafs of beings, the medium muft be more exalted in pro¬ portion. Such is the ancient and popular idea of aether, or aetherial matter. The term if/Ar being thus embarraffed with a va¬ riety of ideas, and arbitrarily applied to fo many dif- ferent things, the later and feverer philofophers choofe to fet it afide, and in lieu thereof fubftitute other more determinate ones. Thus, the Cartefians ufe the term materia fubtilis ; which is 'their aether : and Sir Ifaac Newton, fometimes a fubtile fpirit, as in the clofe of his Principia ; and fometimes a fubtile or cetherial me¬ dium, as in his Optics. The truth is, there are abundance of confiderations, which feem to evince the exiftence of fome matter in the air, much finer than the air itfelf. There is an un¬ known fomething, which remains behind when the air is taken away ; as appears from certain eifedls which we fee produced in vacuo. Heat, Sir Ifaac Newton obferves, is communicated through a vacuum almoft as readily-as through air : but fuch communication can¬ not be without fome interjacent body, to a£l as a me¬ dium. And fuch body may be fubtile enough to pe¬ netrate the pores of glafs; and may be very well con- N° 6. 6 1 iE T H eluded to permeate thofe of all other bodies, and con- JEthee fcquently be diffufed through all the parts of fpace which anfwers to the full charadler of an sether. See , { u s . Heat. The exiftence of fuch an setherial medium being fet¬ tled, that author proceeds to its properties; inferring . it to be not only- rarer and more fluid than air, but ex¬ ceedingly more elaftic and aftive: in virtue of which properties, he fhows, that a great part of the phenome¬ na of nature may be produced by it. To the weight, e. g. of this medium, he attributes gravitation, or ,the weight of all other bodies ; and to its elafticity, the elaftic force of the air and of nervous fibres, and the emiffion, refra&ion, refleftion, and other phenomena of light; as alfo, fenfation, mufcular motion, &c. In fine, this fame matter feems the primum mobile, the firft fource or fpring of phyfical aiStion in the modem fyftem. The Cartefian aether is fuppofed not only'to pervade, but adequately to fill, all the vacuities of bodies ; and thus to make an abfolute plenum in the tmiverfe. But Sir Ifaac Newton overturns this opinion, from divers confiderations by ihowing, that the celeftial fpaces are void of all fenfible refiftance : for, hence it follows, that the matteV contained therein muft be im- menfely rare, in regard the refiftance of bodies is chief¬ ly as their denfity; fo that if the heavens were thus adequately'filled with a medium or matter, how fubtile foever, they would refift the motion of the planets and comets much more than quickfilver or gold. The late difeoveries in electricity have thrown great light upon this fubjeft, and rendered it extremely pro¬ bable that the aether fo often talked of is no other than -the ele&ric fluid, or folar light, which difFufes itfelf throughout the whole fyftem of nature.

If we fuppofe it likewife to be 30 miles, and that mount -Etna can be reprefented by an equilateral triangle, each of whofe fides is 30 miles, we will have an amazing elevation indeed, no lefs than 26 miles perpendicular !—Such a height being beyond all credibility, we muft contra£1 the fides of our tri¬ angle, in proportion to its bafis. We fhall begin with allowing 1 o miles for the difference between a ftraight line from Catania to the fummit, and the length of the road, occafioned by the inequalities of the moun¬ tain and fuppofing the defcent on the other fide to be fomewhat ffiorter, we may call it 15 miles. Mount iEtna will now be reprefented by a fcalene triangle, whofe bafe is 30 miles, its longeft fide 20, and its ffiorteft 15 ; from which proportions we will ftill find Dimer,fions its height to be betwixt eight and nine miles.—This uncertain. Js {till incredible ; and when all the various relations concerning the height of iEtna are compared, we hope it will not be thought prefumptuous in us to give it as our opinion, that the true dimeufions of this mountain are as yet unknown. The following meafures are given by different authors: Height above the furface of the fea, 10,036 feet. One hundred and eighty miles circumference at the bafe.—Faujas de S. Fon in his Volcans du Vivarais. Height 12,000 feet.— Brydone. Tour to Sicily. Height 2500 toifes.—La Platriere, faid as from Recupero. , Height 1950 toifes.—Diameter 30 miles.—Men- telle Geogr. comp. Others make its height only 2000 toifes, and its fuperfices 300 fquare miles. General ap- Concerning the produfts and general appearance of pearance, {his vukano, authors are much better agreed.—The ^ journey from Catania to its fummit has been lately defcribed by three travellers, M. D’Orville, Mr Bry¬ done, and Sir William Hamilton. AH thefe agree, that this fingle mountain affords an epitome of the dif¬ ferent climates throughout the whole world: towards the foot, it is very hot; farther up, more temperate ; and grows gradually more and more cold the higher we afcend. At the very top, it is perpetually covered with fnow : from thence the whole ifiand is fupplied with that article, fo neceffary in a hot climate, and without which the natives fay Sicily could not be inhabited. So great is the demand for this commodity, that the biftiop’s re¬ venues, which are confiderable, arife from the fale of mount ^Etna’s fnow ; and he is faid to draw 1000 /. a- year from one fmall portion lying on the north fide of the mountain. Great quantities of fnow and ice are like¬ wife exported to Malta and Italy, making a eonfiderable -ffitna,, branch of commerce. On the north fide of this fnowy ' v " region, Mr Brydone was affured, that there are feveral fmall lakes which never thaw; and that the fnow mixed with the afhes and fait of the mountain are accumulated to a vaft depth. The quantity of falts contained in this mountain, he, with great probability, conjedtures to be one reafon of the prefervation of its fnows; for fait in- creafes the coldnefs of fnow to a furprifing degree *. * See Cold,, - In the middle of the fnowy regions Hands the great ' crater, or mouth of ./Etna ; from which, though con- trary to the ufual method of travellers, we ffiall begin our particular account of this mountain. Sir William Hamilton defcribes the mater as a little mountain, about a quarter of a mile perpendicular^ and very fteep, fituated in the middle of a gently inclining plain,, of Crater de- I about nine miles in circumference. It is entirely form- bribed, ed of ftones and affies; and, as Mr Hamilton was in¬ formed by feveral people of Catania, had been thrown up about 25 or 30 years before the time (1769) he vi* filed mount ./Etna. Before this mountain was thrown up, there was, only a prodigious large chafm, or gulph, in the middle of the above-mentioned plain; and it has been remarked, that about once in 100 years the top of jEtna falls in ; which undoubtedly muft be the cafe at certain periods, or the mountain behoved conti* nually to increafe in height. As this little mountain, though emitting fmoke from every pore, appeared fo- lid and firm, Mr 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 Mr Hamilton; three miles and a half, according to Mr Brydone ; and three or four, according to Mr D’Or- ville. The infide is crufted over with falts and fulphur of different colours. It goes /helving down, from the top, like an inverted cone ; the depth, in Mr Hamil¬ ton’s opinion,, nearly correfponding to the height of the little mountain. From many places of this fpace iffue volumes of fulphureous fmoke, which being much heavier than the circumambient air, inftead of amend¬ ing in it, roll down the fide of the mountain, till, co¬ ming to a more denfe atmofphere, it/hoots off horizon- tally, and forms a large tra£t in the air, according to the direction of the wind; which, happily for our tra¬ vellers, carried it exa&ly to the fide oppofite to which they were placed. In the middle of this funnel is the tremenduous and unfathomable gulph, fo much cele¬ brated in all ages, both as the terror of this life, and the place of puniihment in the next. From this gulph continually iffue terrible and confufed noifes, which in eruptions are increafed to fuch a degree as to be heard at a prodigious diftance. Its diameter is probably very different at different times: for Mr Hamilton obfer- ved, by the wind clearing away the fmoke from time to time, that the inverted hollow cone was contra£ted almoft to a point; while Mr D’Orville and Mr Bry¬ done found the opening very large. Both Mr Bry¬ done and Mr Hamilton found the crater too hot to defcend into it; but Mr D’Orville was bolder : and accordingly he and his fellow-traveller, faftened to ropes which two or three men held at a diftance for fear of accidents, defcended as near as poffible to the brink of the gulph ; but the fmall flames and fmoke which iffued from it on every fide, and a greeni/h ful¬ phur, and pumice-ftones, quite black, which covered the margin, would not permit them to come fo near iE T N as to have a full view. They only faw diftinftly in J the middle, a mafs of matter which rofe, in the ftiape of a cone, to the height of above 60 feet, and which towards the bafe, as far as their fight could reach, might be 600 or 800. While they were obferving this fub- llance, fome motion was perceived on the north fide, oppofite to that whereon they flood ; and immediately the mountain began to fend forth fmoke and afhes. [ 219 ] ^ T N This eruption was preceded by a fenfible increafe of nothing. whole ifland, and far into the fea on the other fide, form¬ ing a vifible traft in the air, which, as the fun rifes a- L bove the horizon, is fhortened, and at laft confined to the neighbourhood of -/Etna. The moft beautiful part of the fcene, however, in Mr Brydone’s opinion, is the mountain itfelf, the ifland of Sicily, and the numerous iflands lying round it. Thefe laft feem to be clofe to the fkirts of ^Etna; the diftances appearing reduced to its internal roarings; which, however, did not conti¬ nue ; but after a moment’s dilatation, as if to give it vent, the vulca-no refumed its former tranquillity ; but as it was by no means proper to make a long flay in fuch a place, our travellers immediately returned to their attendants. On the fummit of mount iEtna, Mr Hamilton ob- ferves, that he was fenfible of a difficulty in refpiration This mountain is divided into three zones, which Dlvifion in¬ might properly enough be diftinguifhed by the names to three of torrid, temperate, and frigid: they are, however,zones* known by the names of the Piedmontefe, or Regione cul- ta, the cultivated, or fertile region; the Sylvbfa, woody, or temperate zone; and the Region; deferta, the frigid, or defert zone, or region. All thefe are plainly diftin¬ guifhed from the fummit. The Regione deferta is mark- Re^ione from the too great fubtilty of the air, independent of ed out by a circle offnow and ice, which extends on alldeferta. what arofe from the fulphureous fmoke of the moun- fides to the diftance of about eight miles, beginning at tain. Mr Brydone takes no notice of this; which pro- the foot of the crater. Greateft part of this region is bably arofe from the air being in a more rarefied ftate fmooth and even. This is immediately fucceeded by at the time of Mr Hamilton’s obfervation than of Mr the Sylvofa, or woody region ; which forms a circle of Brydbne’s; the barometer, as obferved by the former, (landing at 18 inches and 1 o lines, by the latter at 19 inches 64- lines. Tn thefe high regions there is generally a very vio- lend wind, which, as all our travellers found it conftantly blowing from the fouth, may poffibly be commonly di- redled from that point. Here Mr Brydone’s thermo¬ meter fell to 2 70. Splendor of The top of iEtna being above the common region the ftars 0f vapours, the heavens appear with exceeding great the'to °of fplendor.— Mr Brydone and his company obferved, as the mqft beautiful green, furrounding the mountain on all fides. This region is variegated with a vail number of mountains of a conical form, thrown up by v??tna in thofe eruptions which burft out from its fides. Mr Ha¬ milton counted 44 on the Catania fide, each having its crater, many with large trees flourilhing both within and without the crater. All thefe, except a few of late date, have acquired a wonderful degree of fertility. The circumference of this zone, or great circle, according to Recupero, is not lefs than 70 or 80 miles. It is every¬ one . _ where fucceeded by the Regione culta ; which is much JEtnaf 01 they afeended in the night, that the number of ftars broader than the reft, and extends on all fides to the feemed to be infinitely increafed, and the light of each foot of the mountain.

Mafia, a Sici¬ lian author, affirms, that the African coaft, as well as that of Naples, with many of its iflands, have been dif¬ eovered from the top of iEtna. The vifible horizon here is not lefs than 8 or 900 miles in diameter. The pyramidal ftiadow of the mountain reaches acrofs the del Filolofo, by fome fuppofed to have been built by the Fdofofo. philofopher Empedocles, who took up his habitation here, the better to ftudy the nature of mount iEtna. By others they are fuppofed to be ruins of a temple of Vulcan. They are of brick, and feem to have been or¬ namented with marble. Somewhere in this region alfo, Mr D’Orville found a great oblong block of poliflied marble, eight or ten feet high, and three or four thick; though how it came there, was quite unaccountable to him. From Mr D’Orville’s and Mr Brydone’s accounts, we muft reckon this part of the mountain pretty fteep: but Mr Hamilton fays, that the afeent was fo gradual, as not to be in the leaft fatiguing; and had it not been for the fnows, they might have rode on their mules to the very foot of the crater. The woody region defeends eight or nine miles be- Regionc low the Regione deferta, but differs greatly in the tem-sy'v°fa* perature of its climate. Mr Hamilton obferved a gra¬ dual decreafe of the vegetation as he advanced; the under part being covered with large timber trees, which E e 3 grew : ^ T N r 22Q T iE T N Mtm. grtvr gradually lefs as he approached the third region, at laft they degenerated into the fmall plants of the northern climates. He alfo obferved quantities of ju¬ niper and tanfey; and was informed by his guide, that later in the feafon (he vifited ^Etnain June 1769) there are a great many curious plants, and in fome places rhubarb and faffron in great plenty. In Carrera’s hi- ftory of Catania, there is a lift of all the plants and herbs of ./Etna, in alphabetical order. This region is extolled by Mr Brydone as one of the moft delightful fpots on earth. He lodged for a night in a large cave near .the middle, formed by one of the moft ancient lavas. It is called La Spelonca del Capri- ds, or the goats cavern ; becaufe it is frequented by thofe animals, which take refuge there in bad weather. Here his reft was difturbed by a mountain thrown up in the eruption 1766. It difcharged great quantities of fmoke, and made feveral explofions like heavy can¬ non fired at a diftance; but they could obfcrve no ap¬ pearance of fire. This gentleman likewife vifited the eaftern fide of the Rcgione fylvofa, intending to have afcended that way to the fummit, and defcended again on the fouth fide to Catania; but found it impracticable; though what the infurmountable difficulties were, he does not men- Pruption eftion. On this fide, part of the woody region was de- boiling wa- ftroyed, in 1755, by an immenfe torrent of boiling wa- t£r* ter, which iffued from the great crater. Its traces were ftill very vifible, about a mile and an half broad, and in fome places more. The foil was then only begin¬ ning to recover its vegetative power, which it feems this torrent had deftroyed for 14 years.—Near this place are fome beautiful woods of cork, and evergreen oak, grow¬ ing abfolutely out of the lava,, the foil having hardly filled the crevices; and not far off, our traveller obfer¬ ved feven little mountains that feemed to have been form¬ ed by a late eruption. Each of theft had a regular cup, or crater, on the top; and, in fome, the middle gulph, or Voragine^ as the Sicilians call it, was ftill open. Into thefe gulphs Mr Brydone tumbled down ftones, and heard the noife for a long time after. All the fields round, to a confiderable diftance,. were covered with large burnt ftones difcharged from thefe little vol¬ canoes. ©vergrown The woody region,, efpecially the eaft fide, called ehefinut- Carpinetto, abounds with very large cheftnut-trees; the trees. moft remarkable of which has been called, from its fize, Caftagno de Cento Cavalli, or cheftnut-tree of an. hun¬ dred horfe. Mr Brydone was greatly difapppointed at the fight of this tree, as. it is only a bufh of five large ones growing together: but his guides affured him, that all thefe five were once united into one ftem; and Sig- nior Recupero told him, that he himfelf had been at the expence of carrying up peafants with tools to dig round this bufh of trees, and found all the ftems united below ground in one root. The circumference, as mea- fured by Mefirs Brydone and Glover who accompanied him, amounted to 204 feet. Another of thefe, about a mile and a half higher on the mountain, is called Cajlag- na del Galea: it rifes from one folid ftem to a confide- rablc height; after which it branches out, and is a much finer obieft than the other: this was meafured two feet above the ground, and found to be 76 feet in circum¬ ference. A third, called Cajtagna del Nave, is pretty nearly of the lame fixe; and Mafia, one of the moft efteemed Sicilian authors, affirms that he has feen folid /Etna. oaks there upwards of 40 feet round All thefe grow 1 v— on a thick rich foil, which feems originally to have been formed of afhes thrown out by the mountain. Here the barometer ftood at 26 inches 5 lines and an halfj, indicating an elevation of near 4000 feet. The Piedmontefe diftrict is covered with towns, vU- Region* lages, monafteries, &c. and is well peopled, notwith- Cufu.* ! ftanding the danger of fuch a fituation: but the ferti¬ lity of the foil tempts people to inhabit that country; and their fuperftitious confidence in their faints, with the propenfity mankind have to defpife danger which they do not fee, render them as fecure there as in any o- ther place. Here, Sir William Hamilton obferyes, they keep their vines low, contrary to the cuftom of thofe who inhabit mount Vefuvius; and they produce a ftronger wine, but not in fuch abundance: here alfo many terrible eruptions have burft forth; particularly one in 1669. At the foot of the mountain raifed by Subterraoei that eruption, is a hole, through which Sir Wiftiamouscaverns* J Hamilton defcended, by means of a rope, into feveral fubterraneous caverns, branching out, and extending much farther than he chofe to venture, the cold there being exceffive, and a violent wind extinguifliing fomc of the torches. Many other caverns are known in this, and the other regions of .Etna; particularly one near this place called La Sptlonca della Paloviba, (from the wild pigeons building their nefts there.) Here Mr Brydone was told that fome people had loft.their fenfes, from having advanced too far, imagining-they faw de¬ vils and damned fpirits.—Some of. thefe caverns are made ufe of as magazines for fnow ; , which they are well adapted for, on account of their extreme cold.. Thefe are with great probability fuppofed by Sir Wil- Eam Hamilton to be the hollows made by the iffuing of the lava in eruptions. In this region the river Jdj, fo much celebrated by River Adj.ll the poets, in the fable of Acis and Galatea, takes its ~ [i rife. It burfts out of the earth at once in a large Itream, runs with great rapidity, and about, a mile from its fource throws itfelf into the fea. Its water is remark¬ ably clear; and fo extremely cold, that it is reckoned dangerous to drink it: it is faid,, however,. to have a poifonous quality, from being impregnated with vitriol; in confequence of which cattle have been killed by it. It never freezes,.but is faid often to contract a greater degree of cold than ice. Having thus given an account of this mountain in Appearan- its quiet and peaceable ftate, we muft now defcribe the ces dui l®S appearance it puts on during the time of an eruption,anerUi>tl0B’ when it fpreads deftruttion for many miles round, and is capable of ftriking the boldeft with terror. Sir William Hamilton, who has examined both Ve¬ fuvius and .Etna in a very accurate manner, never had an opportunity of feeing an eruption of the latter; but as he is of opinion that the two vulcanoes agree per— feftly in all refpefts, only that the latter is on a much larger feale than the former, we hope it will not be un¬ acceptable to our readers to give an account of fome of the general appearances of Vefuvius when in a ftate of eruption, the better to help their ideas concerning -Etna. It has been already obferved, that a fmoke con- ftantly iffues from the top of /Etna, and that; its inter¬ nal aoifes never ceafe. The cafe is the fame with Vefu. iE T N [ 221 ] iE T N -ffitna. viiis : and Sir William Hamilton obferved, that in bad weather the fmoke was more confiderable, as well as the noifes much louder, than when it was fair; fo that in bad weather he had frequently heard the inward ex- plofions of the mountain at Naples fix miles diftant from Vefuvius. He alfo obferved the fmoke that ifiued from the mountain in bad weather to be very white, moift, and not near fo offenfive as the fulphureous fteams from various cracks in the fide of the mountain. Signs of an The firft fymptom of an approaching eruption is an approach- increafe of the fmoke in fair weather: after fome time, ing erup- a pUff 0f black fmoke is frequently feen to (hoot up in tion. tjie of the white, to a confiderable height. Thefe puffs are attended with confiderable explofions: for Hamilton’s while Vefuvius was in this ftate, Sir William Hamilton Obferva- went up to its top, which was covered with fnow; and tions, p. 4- perceiving a little hillock of fulphur, about fix feet high, which had been lately thrown up, and burnt with a blue flame at the top, he was examining this pheno¬ menon, when fuddenly a violent report was heard, a column of black fmoke fhot up with violence, and was followed by a reddifh. flame. Immediately a fhowcr of ftones fell; upon which he thought proper to retire. Phenomena of this kind, in all probability, precede the eruptions of ^Etna in a much greater degree.—The fmoke at length appears wholly black in the day-time, and in the night has the appearance of flame ; fhowers of afhes are fent forth, earthquakes are produced, the mountain difcharges volleys of red-hot ftones to a great height in the air. The force by which thefe ftones are projected, as well as their magnitudes, feems to be in proportion to the bulk of the mountain. Signior Recupero affured Mr Brydone, that he had feen im- menfely large ones thrown perpendicularly upwards to the height of 7000 feet, as he calculated from the time they took to arrive at the earth after beginning to defcend from their greateft elevation. The largeft ftone, or rather rock, that was ever known to be emit¬ ted by Vefuvius, was 12 feet long and 45 in circum¬ ference. This was thrown a quarter of a mile ; but much larger ones have been thrown out by mount J£.t- «a, almoft in the proportion in which the latter exceeds Vefuvius in bulk. Along with thefe terrible fymp- toms, the fmoke that iftiies from the crater is fome- times in a highly electrified ftate. In this cafe, the imall allies which are continually emitted from the cra¬ ter, are attracted by the fmoke, and rife with it to a great height, forming a vaft black, and to appearance denfe, column; from this column continual flafties of Thunder & forked or zig-zag lightning ifiue, fometimes attended ftorndie thunder, and fometimes not, but equally powerful fmoke. with ordinary lightning. This phenomenon was ob¬ ferved by Sir William Hamilton in the fmoke of Vefu¬ vius, and has alfo been taken notice of in that of ./Et¬ na ; and where this eleCtrified fmoke hath fpread over a trad of land, much mifchief hath been done by the lightning proceeding from it. When thefe dreadful appearances have continued fometimes four or five months, the lava begins to make its appearance. This is a ftream of melted mineral matters, which in Vefuvius commonly boils over the top, but very feldom does, fo in ./Etna; owing to the great weight of the lava, which long before it can be raifed to the vaft height of mount ./Etna, burfts out through fome weak place in its fide. Upon the ap¬ pearance of the lava, the violent eruptions of the moun- -®tna. tain generally, though not always, ceafe; for if this v burning matter gets not fufficient vent, the commo¬ tions increafe to a prodigious degree.—-In the night¬ time the lava appears like a ftream of fire, accompanied with flame: but in the day-time it has no fuch appear¬ ance; its progrefs is marked by a white fmoke, which by the refledion of the red-hot matter in the night af- fumes the appearance of flame. All the abovementioned fymptoms preceded the great Eruption 111 eruption of .ditna in 1669. For feveral months before1 ^ the lava broke forth, the old mouth, or great crater on the fummit, was obferved to fend forth great quantities of fmoke and flame; the top had fallen in, fo that the mountain was much lowered; the iflands alfo of Volcan and Stromboli, twro volcanoes to the weftward of Sicily, were obferved to rage more than ufual.—Eighteen days before the eruption, the Sky was very thick and dark, with thunder, lightning, frequent concuflions of the earth, and dreadful fubterraneous bellowings. On the 1 ith of March, fome time before the lava got vent, a rent was opened in the mountain twelve miles in length, into which, when ftones were thrown down, they could not bejreard to ftrike the bottom. Burning rocks, 60 palms (15 of our feet) in length, were thrown to the diftance of a mile; others of a lefier fize were carried three miles off; the internal noifes of the moun¬ tain were exceedingly dreadful, and the thunder and lightning from the fmoke fcarce lefs terrible than they. When the lava at laft got vent, it burft out of a vineyard, 20 miles below the great crater, and fprung up into the air to a confiderable height. Here it formed a mountain of ftones and allies, not lefs, as Sir Wm Hamilton conjectures, than half a mile perpendicular in height, and three miles in circumference. For 54 days neither fun nor ftars had appeared : but foon af¬ ter the lava got vent, the mountain became very quiet. The terrible effefts of this fiery ftream may be imagined from its amazing extent; being, as Sir Wm Hamilton obferves, no lefs than 14 miles long, and in many pla¬ ces fix in breadth. In its courfe, it deftroyed the ha¬ bitations of near 30,000 perfons ; and meeting with a lake four miles in compafs, it not only filled it up, though feveral' fathom deep, but made a mountain in the place of it. Having reached Catanea, it deftroyed part of its walls, and ran for a confiderable length into the fea, forming a fafe and beautiful harbour ; which, however, was foon filled up by a frefh torrent of the fame inflamed matter. It is not eafy for thofe who have never been prefent Phenome- at thofe terrible operations of nature, to reprefent to na at ,the their minds the horror which muft attend the breaking forth of the lava ; for though the giving vent to this java< burning matter generally produces a ceffation of the violent efforts of the internal fire, yet at the very in- ftant of its explofion fcarce any thing can be conceived fo dreadful. See Vesuvius. When the lava firft iffues, it appears very fluid, and Hamilton’s runs with the rapidity of a fwift river; but even then it obierva- furprifingly refills the impreffion of folid bodies: for SirtIons’ 1’’I0* Wm Hamilton could not pierce that of Vefuvius with a flick driven againft it with all his force ; nor did the largeft ftone he was able to throw upon it fink, but made a flight impreffion, and then floated along. This hap¬ pened almoft at the very mouth, when the lava appear- E e 3 ed iE T N [ 222 ] iE T JEtna. ed liquid as water, and when he faw it running with a 1 v 1 rapidity equal to the river Severn at the panage near Briftol.—A defcription'of the lava iffuing from mount iEtna in 1669 was fent to the court of England by- Lord Winchelfea, who at that time happened to be at Catania in his way home from an embaffy at Conftanti- nople. His account is not now to be procured ; but Mr Hamilton found a copy in Sicily, and hath given Lava of an extraft, part of which follows. “ When it was i669defcri-night, I went upon two towers in divers places; and I hed. could plainly fee, at ten miles diftance, as we judged, the fire begin to run from the mountain in a direft line, the flame to afcend as high and as big as one of the greateft fteeples in your Majefty?s kingdoms, and to throw up great ftones into the air; I could difcern the river of fire to defcend the mountain of a terrible fiery or red colour, and ftones of a paler red to fwim there¬ on, and to be fome as big as an ordinary table. We could fee this fire to move in feveral other places, and all the country covered with fire, afcending with great flames in many places, fmoking like to a violent fur¬ nace of iron melted, making a noife with the great pieces that fell, efpecially thofe that fell into the fea. A cavalier of Malta, who lives there, and attended me, told me, that the river was as liquid, where it iflues out of the mountain, as water, and came out like a torrent with great violence, and is five or fix fathom deep, and as broad, and that no ftones fink therein. The account given in the Philofophical Tranfa&ions is to the fame purpofe. We are there told, that the lava is “ nothing elfe than diverfe kinds of metals and minerals, rendered liquid by the fiercenefs of the fire in the bowels of the earth, boiling up and gufhing forth as the water doth at the head of fome great ri¬ ver ; and having run in a full body for a Hone’s caft or more, began to cruft or curdle, becoming, when cold, thofe hard porous ftones which the people call Sciarri” Thofe, though cold in comparifon of v/hat firft iflues from the mountain, yet retained fo much heat as to refemble huge cakes of fea-coal ftrongly ignited, and came tumbling over one another, ’nearing down or burning whatever was in their way. — In this manner the lava proceeded (lowly on till it came to the fea, when a moft extraordinary conflidt enfued betwixt the two adverfe elements. The noife was vaftly more dreadful than the loudeft thunder, being heard thro’ the whole country to an immenfe diftance ; the water feemed to retire and diminiftr before the lava, while clouds of vapour darkened the fun. The whole fifti on the coaft were deftroyed, the colour of the fea itfelf was changed, and the tranfparency of its waters loft for many months. While this lava was ifiuing in fuch prodigious quan¬ tity, the merchants, whofe account is recorded in the Philofophical Tranfadtions, attempted to go up to the mouth itfelf; but durft not come nearer than a furlong, left they (hould have been overwhelmed by a vaft pil¬ lar of aflies, which to their apprehenfion exceeded twice the bignefs of St Paul’s fteeple in London, and went up into the air to a far greater height; at the mouth itfelf was a continual noife, like the beating of great waves of the fea againft rocks, or like diftant thunder, which fometimes wns fo violent as to be heard 60, or even 100 miles off; to which diftance alfo part of the afttes were carried. Some time after, having gone up, they found the mouth from whence this terrible deluge -®ma. iflued to be only a hole about 1 o feet diameter. This is alfo confirmed by Mr Brydone; and is probably the ofth^holfr fame through which Sir W™ Hamilton defcended into whence the the fubterranean caverns already mentioned. lava iffued. Mount iEtna, as we have already remarked, has Antiquity been a celebrated volcano from the remoteft antiquity, of the erup* Diodorus Siculus mentions eruptions of it as happening ti0115* 500 years before the Trojan war, or 1693 years before the Chriftian sera. From Homer’s filence with regard to the phenomenon of iEtna, it is to be prefumed that the volcano had been many-ages in a ftate of inadtivity, and that no tradition of its burning remained among the inhabitants at the time he compoied his Odyffey ; perhaps it never had emitted flames fince the country wjfs peopled. The firft eruption taken notice of by an¬ cient, but by no means cotemporary authors, happened before the Greeks landed on the illand, and is fuppofed to have feared the Sicani from the eaft part of Sicily. Pindar, quoted above, is the oldeft writer extant who fpeakg of ./Etna as a volcano. The firft recorded erup¬ tion was in the time of Pythagoras. Plato was invited by the younger Dyonifius to examine the ftate of the mountain after the fixth. It threw up flames and lava near an hundred times between that period and the battle of Pharfalia; it was particularly furious while Sextus Pompeius was adding the horrors of war to its devaftations. Charlemagne happened to be at Catania during one of the eruptions ; and from his reign the chronicles mention fifteen down to that of the year 1669, the moft terrible of them all. Since 1669 there have been feveral eruptions, but none of them compa¬ rable to it. In that which happened in 1766, the lava fprung up into the air to a confiderable height, twelve miles below the fummit; but formed a ftream only fix miles in length and one mile in breadth. The laft eruption happened in 1787. From the ift Account of to the 10th of July, there were figns of its approach, the late e- On the 1 ith, after a little calm, there was a fubterra- ruP'Ion> neous noife, like the found of a drum in a clofe place,17 ^ and it was followed by a copious burft of black fmoke. It was then calm till the 15th, when the fame progno- ftics recurred. On the 17th, the fubterraneous noife was heard again; the fmoke was more abundant, flight (hocks of an earthquake followed, and the lava flowed from behind one of the two little mountains which form the double head of /Etna. On the 18th, while the fpedtators were in anxious expectation of a more fevers eruption, all was quiet, and continued fo more than. 12 hours : foon after they perceived fome new (hocks, accompanied with much noife; and the mountain threw out a thick fmoke, which, as the wind.was wefterly, foon darkened the eaftern horizon: two hours after¬ wards a (hower of fine black brilliant fand defcended 1 on the eaft fide it was a ftorm of ftones; and, at the foot of the mountain, a deluge of flaflres of fire, of: fcoria and lava. Thefe appearances continued the whole day; at the fetting of the fun the feene changed. A number oF conical flames rofe from the volcano; one on the north, another on the fouth,, were very confpicuous, and rofe and fell alternately. At three in the morning, the mountain appeared cleft, and the fummit feemed a burn¬ ing mafs. The cones of light which arofe from the crater were of an inunenfe extent, particularly the two ^ T N L 223 ] A F F JEtna. juft mentioned. The two heads feemed to be cut away; ^tnafalr. an(j at thejr feparation was a cone of flame, feemingly v compofed of many leffer cones. The flame feemed of the height of the mountain placed on the mountain ; fo that it was probably two miles high, on a bafe of a mile and a half in diameter. This cone was ftill co¬ vered with a very thick fmoke, in which there appear¬ ed very brilliant flafhes of lightning, a phenomenon which JEtna had not before aflbrded. At times, founds like thofe from the explofion of a large cannon were heard feemingly at a lefs diftance than the mountain. From the cone, as from a fountain, a jet of many fla¬ ming volcanic matters were thrown, which were car¬ ried to the diftance of fix or feven miles : from the bafe of the cone a thick fmoke arofe, which, for a mo¬ ment, obfcured fome parts of the flame, at the time when the rivers of lava broke out. This beautiful ap¬ pearance continued three quarters of an hour. It be¬ gan the next night with more force; but continued only half an hour. In the intervals, however, iEtna continued to throw out flames, fmoke, Hones ignited, and ftiowers of fand. From the 20th to the 22d, the appearances gradually ceafed. The ftream of lava was carried towards Bronte and the plain of Lago. After the eruption, the top of the mountain on the weftefn fide was found covered with hardened lava, fcoria, and ftones.' The travellers were annoyed by fmoke, by ftiowers of fand, mephitic vapours, and ex- ceflive heat. They faw that the lava which came from the weftern point divided into two branches, one of which was directed towards Libeccio; the other, as we have already faid, towards the plain of Lago. The lava on the weftern head of the mountain, had from its va¬ rious fliapes been evidently in a ftate of fufion : from one of the fpiracula, the odour was ftrongly that of li¬ ver of fulphur. The thermometer, in defcending, was at 40 degrees of Farenheit’s fcale; while near the lava, in the plain of Lago, it was 140 degrees. The lava extended two miles; its width was from 13^ to 21 feet, and its depth 13-! feet. Thefe are the moft remarkable circumftances we have been able to collect, that might ferve to give an ade¬ quate idea of this famous mountain.—Many things, however, concerning the extent, antiquity, fffc. of the - lavas, remain to be difcufled, as well as the opinions of philofophers concerning the origin of the internal fire which produces fo much mifchief: but the confideration of thefe belongs to the general article Volcano,' to which the reader is referred.—The fate of Catania and Hybla, which have often been deftroyed by eruptions, will be mentioned under thefe two words. JEtna fait, Sal JEt/ te, a name given by fome au¬ thors to the fal ammoniac, which is found on the fur- face and fides of the openings of JEtna, and other burning mountains after their eruptions ; and fome- times on the furface of the ferruginous matter which they throw out. This fait makes a very various ap¬ pearance in many cafes; it is fometimes found in large and thick cakes, fometimes only in form of a thin powder, fcattered over the furface of the earth and ftones. Some of this fait is yellow, fome white, and fome greenifti. This fait is a concrete of nitre, fulphur, and vitriol, burnt and fublimed together; Borelli found oace a vaft quantity of this fait on mount JEtna, and tried many experiments on it; from whence he con- /Etolarcha eluded, that this fait is fo far from occafioning the ,ex- ^g-e|!j.ion plofions of that mountain, as fome have fuppofed, that it does not exift in it, but is formed during the burn¬ ing. Phil. Tranf. N' 100. iETOLARCHA, in Grecian antiquity, the prin¬ cipal magiftrate or governor of the ^Etolians. AFER (Domitius), a famous orator, born at Nif- mes, flourilhed under Tiberius and the three fucceed- ing emperors. Quintilian makes frequent mention of him, and commends his pleadings. But he difgraced his talents, by turning informer againft fome of the moft diftinguiftied perfonages in Rome. Quintilian, in his youth, cultivated the friendfhip of Domitius very afti- duoufly. He tells us that his pleadings abounded with pleafant ftories, and that there were public colleftions of his witty fayings, fome of which he quotes. He alfo mentions two books of his “ On Witneffes.” Do¬ mitius was once in great danger from an infeription he put upon a ftatue erefted by him in honour of Cali¬ gula, wherein he declared that this prince was a fecond time a conful at the age of 27. This he intended as an encomium, but Caligula taking it as a farcafm up¬ on his youth, and his infringement of the laws, raifed a procefs againft him, and pleaded himfelf in perfqn, Domitius, inftead of making a defence, repeated part of the emperor’s fpeech with the higheft marks of ad¬ miration; after which he fell upon his knees, and, beg¬ ging pardon, declared, that he dreaded more the elo¬ quence of Caligula than his imperial power. This piece of flattery fucceeded fo well, that the emperor not only pardoned, but alfo raifed him to the conful- ftiip. Afer died in the reign of Nero, A. D. 59. AFFA, a weight ufed on the Gold Coaft of Gui¬ nea. It is equal to an ounce, and the half of it is cal¬ led eggeba. Moft of the blacks on the Gold Coaft give thefe names to thofe weights. AFFECTION, in a general fenfe, implies an at¬ tribute infeparable from its fubjedL Thus magnitude, figure, weight, &c. are affections of all bodies ; and love, fear, hatred, &c. are affedtions of the mind *. * ^tMorat Affection, fignifying a fettled bent tf mind to aIlc^ before there can be an opportunity to exerffit upon any *'aff10n' particular objedt; whereas Affedtion can never be ori¬ ginal, becaufe, having a fpecial relation to a particular objedt, it cannot exift till the objedt have once at leaft been prefented. It is alfo diftinguifhable from Pafiion, which, depending on the real or ideal prefence of its objedt, vanifhes with its objedt: whereas Affedtion is a lafting connexion; and, like other connedtions, fubfifts even when we do not think of the perfon. A familiar example will illuftrate this. There may be in one per- fon’s mind a difpolition to gratitude, which,, through want of an objedt, happens neVer to be exerted ; and’ * which therefore is never difeovered even by the perfon- himfelf. Another, who has the fame difpofition, meets with a kindly office that makes him grateful to his bene- fadtor: An intimate connedtion is formed between them,, termed affeftion : which, like other connedtions, has a permanent exiftence, though not always in. view. The A F F [ 224 ] A F F Affection afFeftion, for the moft part, lies dormant, till an cppor- iAffinit' tunity °^er ^or e^erting ^ : in circumilance, it is t ‘ ^ ' converted into paflion of gratitude ; and the opportu¬ nity is eagerly feized of teftifying gratitude in the warmeft manner. Affection, among phyficians, fignifies the fame as"difeafe. Thus the hyfteric affettwn is the fame with the hylleric difeafe. AFFERERS, or Afferors, in law, perfons ap¬ pointed in court-leets, courts-baron, &c. to fettle, upon oath, the fines to be impofed upon thofe who have been guilty of faults arbitrarily puniihable. AFFETUOSO, or Con Affetto, in the Italian mufic, intimates that the part to which it is added ought to be played in a tender moving way, and confequently rather flow than faft. AFFIANCE, in law, denotes the mutual plight¬ ing of troth between a man and woman to marry each other. AFFIDAVIT, fignifies an oath in writing, fworn before fome perfon who is authorifed to take the fame. AFFINITY,among civilians, implies a relation con- trafted by marriage ; in contradiftin&ion to confangui- nity, or relation by blood.—Affinity does not found any real kinffiip; it is no more than akindof fi£tion, intro¬ duced on account of the clofe relation between hufband and wife. It is even faid to ceafe when the caufe of it ceafes : hence a woman who is not capable of being a witnefs for her hufband’s brother during his lifetime, is allowed for a witnefs when a widow, by reafon the affinity is diffolved. Yet with regard to the contract¬ ing marriage, affinity is not difiblved by death, though it be in every thing elfe. There are feveral degrees of affinity, wherein mar¬ riage was prohibited by the law of Mofes : thus, the fon could not marry his mother, nor his father’s wife (Lev. xviii. 7. et feq.) : the brother could not marry his After, whether fhe were fo by the father only or by the mother only, and much lefs if ffie was his After both by the fame father and mother: the grandfather could not marry his grand-daughter, either by his fon or daughter. No one could marry the daughter of his father’s wife; nor the lifter 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 fide. The father-in-law could not marry his daugh¬ ter-in-law : nor the brother the wife of his bro¬ ther, while living; nor even after the death of his brother, if he left children. If he left no children, the furviving brother was to raife up children to his deceafed brother, by marrying his widow. It was for¬ bidden to marry the mother and the daughter at one time, or the daughter of the mother’s fon, or the daughter of her daughter, or two filters together. It is true the patriarchs before the law married their filters, as Abraham married Sarah, who was his father’s daughter by another mother; and two filters together, as J^cob married Rachel and Leah; and their own fillers by both father and mother, as Seth and Cain. But thefe cafes are not to be propofed as examples : becaufe in fome they were authoiifed by neceffity ; in others by cuftom; and the law as yet was not in being. If fome other examples may be found, either before or fince the law, the fcripture exprefsly difapproves of them, as Reuben’s inceft with Balah his father’s con- N® 6. 5 cubine, and the aCtion of Ammon with his After Ta- Affinity' mar; and that of Herod-Antipas, who married He- il rodias his filler-in-law, his brother Philip’s wife, while . ^ loa‘ her hulband was yet living. Affinity is alfo ufed to denote conformity or agree¬ ment : Thus we fay, the affinity of languages, the af¬ finity of words, the affinity of founds, &c. Affinity, or Elective Attraction, are terms ufed by modern chemifts to exprefs that peculiar pro- penfity which different fpecies of matter have to unite and combine with certain other bodies exclufively, or in preference to any other connection. AFFIRMATION, in logic, the afferting the truth of any propolition. Affirmation, in law, denotes an indulgence allow¬ ed to the people called Quakers ; who, in cafes where an oath is required from others, may make a folemn af¬ firmation that what they fay is true; and if they make a falfe affirmation, they are fubjeCt to the penalties of perjury. But this relates only to oaths taken to the government, and on civil occafions; for Quakers are not permitted to give their teftimony in any criminal cafe, &c. Affirmation is alfo ufed for the ratifying or con¬ firming the fentence or decree of fome inferior court: Thus we fay, the houfe of lords affirmed the decree of the lord chancellor, or the decree of the lords of feffion. AFFIRMATIVE, in grammar. Authors diftin- guilh affirmative particles ; fuch is, yes.—The term affirmative is fometimes alfo ufed fubftantively. Thus we fay, the affirmative is the more probable fide of fhe queftion : there were fo many votes, or voices, for the affirmative. AFFIX, in grammar, a particle added at the clofe of a word, either to diverfify its form or alter its figni- fication. We meet with affixes in the Saxon, the Ger¬ man, and other northern languages; but more efpecially in the Hebrew, and other oriental tongues. The He¬ brew affixes are Angle fyllables, frequently Angle-letters, fubjoined to nouns and verbs; and contribute not a little to the brevity of that language. The oriental languages are much the fame as to the radicals, and differ chiefly from each other as to affixes and prefixes. AFFLATUS, literally denotes a blaft of wind, breath, or vapour, ftriking with force againft another body. The word is Latin, formed from ad “ to,” and flare “ to blow.” Naturalifts fometimes fpeak of the afflatus of ferpents. Tully ufes the word figuratively, for a divine infpiration ; in which fenfe, he aferibes all great and eminent accomplilhments to a divine afflatus. The Pythian prieftefs being placed on a tripod or per¬ forated ftool, over a holy cave, received the divine afflatus, as a late author expreffes it, in her belly ; and being thus infpired, fell into agitations, like a phrene¬ tic ; during which ffie pronounced, in hollow groans and broken fentences, the will of the deity. This af¬ flatus is fuppofed, by fome, to have been a fubterra- neous fume, or exhalation, wherewith the prieftefs was literally infpired. Accordingly, it had the effedts of a real phyfical difeafe ; the paroxyfm of which was fo vehement, that Plutarch obferves it fometimes proved mortal. Van Dale fuppofes the pretended enthufiafm of the Pythia to have arifen from the fumes of aro¬ matics. AFFLICTION, is not itfelf, in propriety of medi¬ cal 1 A F R [ 225 ] A F R Afforage cal fpeech, a difeafe, but it produces many : for what- U ever excites envy, anger, or hatred, produces difeafes l ic:i‘ , from 'tenfe fibres ; as whatever excites fear, grief, joy, or deKght, begets difeafes from relaxation. AFFORAGE, in the French cuftoms, a duty paid to the lord of a diftrift, for permilfion to fell wine, ox- other liquors, within his feignory. Afforage is alfo ufed for the rate or price of provifions laid and fixed by the provoft or fheriffs of Paris. AFFORESTING, Afforestatio, the turning ground into foreft. The Conqueror, and his fuccel- fors, continued afforefting the lands of the fubjedt for many reigns ; till the grievance became fo notorious, that the people of all degrees and denominations were brought to fue for relief; which was at length obtain¬ ed, and coinmiffions were granted to furvey and pe¬ rambulate the foreft, and feparate all the new afforefted lands, and re-convert them to the ufes of their proprie¬ tors, under the name and quality of purlieu, or pcuralle land. AFFRAY, or Affrayment, in law, formerly fig- nified the crime of affrighting other perfons, by ap¬ pearing in unufual armour, bi-andiftxing a weapon, &c. but, at prefent, affray denotes a fkirmifh or fight be¬ tween two or more. AFFRONTEE, in heraldry, an appellation given to animals facing one another on an efcutcheon ; a kind of bearing which is otherwife called confrontee, and ftands oppofed to adoffee. AFFUSION, the ad of pouring fome fluid fub- ftance on another body. Dr Grew gives feveral expe¬ riments of the ludation arifing from the affufion of divers menftruums on all forts of bodies. Divines and church hiftorians fpeak of baptifm by affufion ; which amounts to much the fame with what we now call fprinkling. AFRANIUS, a Latin poet, who wrote comedies in imitation of Menander, commended by Tully and Quintilian: he lived in the 170th olympiad. AFRICA (according to Bochart, from a Punic word, fignifying Ears of Corn); one of the four great divifions, by the moderns called quarters, of the world, and one of the three called by the Greeks or ■continents. By them it was alfo called Libya. Africa lies fouth of Europe, and weft of Afia. It is bounded on the north by the Mediterranean, which fe- parates it from the former ; on the north-eatt, by the Red Sea, which divides it from Afia, and to which it is attached by a neck of land called the IJlhmus of Suez, about 60 miles over, feparating the Mediterranean from the Red Sea. On the weft, fouth, and eaft, it is bound¬ ed by the main ocean : fo that it is properly a vaft peninfula, bearing fome faint refemblance of a pyra¬ mid, the bafe of which is the northex-n part, running a- long the fliores of the Mediterranean; and the top of the pyramid is the moft foutherly point, called the Cape of Good Hope. Its greateft length from north to fouth is 4300 miles, and its greateft breadth from eaft to weft is 3500 miles; reaching from Lat. 37° N. to35°S. and from Long. 170 W. to 50° E. Though the greateft part of this continent hath been in all ages unknown both to the Europeans and Afia- tics, its fituation is more favourable than either Europe or Afia for maintaining an intex-courfe with other na¬ tions. It ftand, as it were, in the centre of the three Von. I. Part I. other quarters of the globe ; and has thereby a much nearer communication with Europe, Afia, and Ame¬ rica, than any one of thefe has with another. For,( 1.) It is oppofite to Europe in the Mediterranean, for al- moft 1000 miles in a line from eaft to weft ; the dis¬ tance feldom too miles, never too leagues, and fome- times not above 20 leagues. (2.) It is oppofite to Afia for all the length of the Red Sea, the diftance fome- timee not exceeding five leagues, feldcm fifty. (3.) Its coaft for the length of about 2O00 miles lies oppofite to America at the diftance of from 500 to 700 leagues, including the iflands : whereas America, unlefs where it may be a terra incognita, is no where nearer Europe than 1000 leagues ; and Afia, than 2500. As the equator divides this continent almoft in the middle, the far greateft part of it is within the tro-. pics; and of confequence the heat in fome places is al¬ moft infupportable by Europeans, it being there great¬ ly increafed by vaft deferts of burning fand.—It can¬ not be doubted, however, that, were the country well cultivated, it would be extremely fertile ; and would produce in great abundance not only the neceflaries, but alfo the luxuries, of life. It has been aflerted, that the fugars of Barbadoes and Jamaica, as alfo the gin¬ ger, cotton, rice, pepper, pimento, cocoa, indigo, &c. of thefe illands, would thrive in Africa to as much perfe&ion as where they ax-e now produced. Nor can it be doubted, that the Eaft Indian fpices, the tea of China and Japan, the coffee of Mocha, &c. would all thrive in fome parts of the African coaift; as this con¬ tinent has the advantage of feeling no cold, the climate being either very warm or very temperate. Whatever may be the cafe with the internal parts of Africa, it is certain that its coafts are well watered with many very confiderable rivers. The Nile and the Niger may be reckoned among the largeft in any part of the world, America excepted. The firft difeharges itfelf into the Mediterranean, after a prodigious courfe from its fource in Abyffinia. The origin neither of the Nile, nor of the Niger, is certainly known ; but that of the latter is fuppofed to run through a tra& of land little lefs than 3000 miles. Both thefe rivers annually •overflow their banks, fertilizing by that means the coxintries through which they pafs. The Gambia and Senegal rivers are only branches of the Niger. Many vaft ridges of mountains alfo run through different parts of this continent; but their extent is very little known. Some of the moft remarkable are, (1.) Thofe called Atlas, lying between the 20th and 25th degree of north latitude, and fuppofed almoft to divide the continent from eaft to weft. (2.) The mountains of the moon, fo called on account of their great height ; fuppofed to be the boundaries between Abyffinia and fome of the interior kingdoms. (3.) The mountains of Sierra Leona, fo called on account of their abounding with lions, and likewife fuppofed to be the boundaries of fome of the nations. (4.) Thofe called by the ancients the mountains of God, on account of their being fub- jedt to perpetual thunder and lightning. Of all thefe, however, little more is known than their names. To what we have already faid concerning the pro¬ duce of Africa, we may add, that no part of the world abounds with gold and filver in a greater degree. Here alfo are a prodigious number of elephants; and it is furprifing, that neither the ancient nor modern Euro- F f peans, A F R r 226 1 A F R peans, notwithftanding their extravagant and infatiable thirft after gold and filver, Ihould have endeavoured to eftablifli themfelves effe&ually in a country much nearer to them than either America or the Eaft Indies ; and where the objefts of their defire are found in equal, if not greater, plenty. Next to gold and filver, copper is the moft valuable metal; and on this continent is found in great plenty, infomuch that the mountains of Atlas above mentioned are faid all to be compofed of copper ore. In fhort, Africa, though a full quarter of the globe, ftored with -an inexhauftible treafure, and capable of producing al- moft every neceffary, conveniency, and luxury of life, within itfelf, feems to be utterly negle&ed both by its own inhabitants and all other nations: the former, being in a favage ftate, are incapable of enjoying the bleffings offered them by nature ; and the latter taking no farther notice of the inhabitants, or their land, than to obtain at the eafieft rate what they procure with as little trouble as poffible, or to carry them off for flaves to their plantations in America. Only a fmall part of this continent was known to the ancients, viz. the kingdom of Egypt, and the nor¬ thern coaft, comprehending little more than what is now known by the name of Barb ary. It was divided into Africa Propria, and Africa Anterior. Africa Pro¬ pria comprehended only the Carthaginian territories. Africa Interior comprehended all other nations to the fouthward of thefe territories, or thofe at a greater di- ftance from Rome. The only kingdoms, however, with which the Romans had any connexion, were the Numidians, the Mauritanians, and the Gartuli. All thefe, as well as Egypt, were fwallowed up by that enormous power, and reduced to the condition of Ro¬ man provinces. But the Romans never feem to have penetrated beyond the tropic of cancer. There appears, indeed, to have been fome intercourfe between them and the Ethiopians: but the latter always preferred their liberty; and we find their queen Candace men¬ tioned in the times of the apoftles, when the Roman power was at its higheft pitch. Between the tropic of cancer and the equinoftial line, a multitude of favage nations were fuppofed to have their refidence, known by the names of Melano- gaetuli, Nigritse, Blemmyes, Dolopes, Aftacuri, Lo- tophagi, Ichthyophagi, Elephantophagi, &c. (which are taken notice of, as well as the others already men¬ tioned, under their proper names); but that Africa was a peninfula, feems to have been totally unknown both to the Europeans and Afiatics for many ages.— It is probable indeed, that fome of the Phenicians, and their offspring the Carthaginians, were not fa ignorant; as they carried navigation to a much greater height than either the Greeks or Romans : but their difcove- ries were all concealed with the greateft care, left other nations ftiould reap the benefit of them ; and accord¬ ingly we can now find no authentic accounts concern¬ ing them. The navigation round Africa, in particular, is recorded by the Greek and Roman writers rather as a ftrange amufing tale than as. a real tranfa&ion ; and as neither the progrefs of the Phenician and Carthagi¬ nian difcoveries, nor the extent of their navigation, were communicated to the reft of mankind, all memorials of their extraordinary fkill in naval affairs feem in a great aieafure to have periffied, when the maritime power of the former was annihilated by Alexander’s eonqueft of Africa. Tyre, and the empire of the latter was overturned by -v””*- the Romans. That the peninfula of Africa, however, was in reality failed round by the Phenicians, we have oh indifputable authority ; for fome of that nation un¬ dertook the voyage, at the command of Necho king of Egypt, about 604 years before the Chriftian sera. They failed from a port in the Red-fea, and after three years returned by the Mediterranean : and the very obje&ions that were made to the veracity of their accounts at that time, are unanfwerable proofs to us that this voyage was really accomplifhed. They pre¬ tended, that, having failed for fome time, the fun be¬ came more and more vertical, after which he appeared in the north, and feemed to recede from them : that as they returned, the fun gradually feemed to move fouthwards; and, after becoming vertical once more, appeared then in the fouth fide of them as before they fet out. This, which we know muft certainly have been the cafe, was deemed incredible at that time, and uni- verfal ignorance concerning the extent of this continent prevailed till the 15th century. The firft attempts to¬ wards attaining a knowledge of Africa was made by the Portuguefe in 1412. Notwithftanding their vici¬ nity, they had never ventured beyond Cape Non, fituated in about N. lat. 270. : it had received its name from a fuppofed impoffibility of paffing it. This year they proceeded 160 miles farther, to Cape Bojador; which ftretching a confiderable way into the Atlantic ocean, with rocky clifts, appeared fo dreadful to the naviga¬ tors, that they returned without any attempt to pafs it. In an attempt to double this formidable cape, they difcovered the Madeira iflands in 1419 : but Cape Bojador continued to be the boundary of their conti¬ nental difcoveries till 1433 ; when they penetrated within the tropics, and in a few years difcovered the river Senegal, Cape de Verd, and the ifiands which lie off that promontory. In '449, the weftern iflands, called the Azores, were difcovered : and in 1471, they firft penetrated beyond the line ; and were furprifed to find, that the torrid zone, contrary to the opinion of the ancients, who imagined it to be burnt up with heat, was not only habitable, but fertile and populous. In 1484, they proceeded 1500 miles beyond the line ; fo that they began to entertain hopes of finding that way a paffage to the Eaft Indies : and two years after¬ wards, the Cape of Good Hope was difcovered by Bar¬ tholomew de Diaz ; but it was not till the year 1497, that the Portuguefe, under Vafquez de Gama, actually doubled this cape, and difcovered the true fliape of the continent. Thus the coafts of Africa were made per- fedfly known ; and probably the knowledge concerning its interior parts would have been much greater than it is, had not the general attention been called off from this continent by the difcovery of America in 1492. The Romans for a long time maintained their power. in Africa: but in the year 426, Bonifacius,. fupreme governor of all the Roman dominions in this quarter, being compelled to revolt by the treachery of another general called Aetius, and finding himfelf unable to contend with the whole ftrength of the Roman em¬ pire, carted in Genferic king of the Vandals to his aid;- who thereupon abandoned the provinces he had feized in Europe, and paffed over into Africa. Bonifacius, however J; A F R L 227 ] A F R Africa, however, being foon after reconciled to his emprefs -'-v ' placidia, endeavoured in vain to perfuade the Vandals to retire. Hereupon a war enfued, in which the bar¬ barians proved vidtorious, and quickly over-ran all the Roman provinces in Africa. In the year 435, a peace was concluded; when Numidia and fome other coun¬ tries were ceded to the Vandals, who foon after feized all the reft. Thefe barbarians did not long enjoy their ill-gotten jaoflefiiens: for, about the year 533, Be- lifarius drove them out, annexing the provinces to the eaftern empire ; and in 647, the Saracens, having conquered Mefopotamia, Egypt (which anciently was not included in the meaning of the word Africa), Phenicia, Arabia, and Paleftine, broke like a torrent into Africa, which they quickly fubdued. Their vaft empire being in 936 divided into feven kingdoms, the African ftates retained their independency long after the others were fubdued by the Turks: but in the be¬ ginning of the 16th century, being afraid of falling un¬ der the yoke of Spain, they invited the Turks to their afliftance; who firft protefted, and then enflaved, them. They ftill continue in a kind of dependence on the Ot¬ toman empire. They are not, however, properly fpeak- ,ing, the fubjefts of the grand Signior, but call him their protettor, paying him an annual tribute. On the coafts, the natives are almoft all addicted to piracy; and with fuch fuccefs have they carried on their employment, that the greateft powers in Europe are become their tributaries, in order to procure liberty to trade on the . Mediterranean. Concerning even thofe ftates which are neareft to Europe, very little is known : but the interior nations are fcarce known by name ; nor do almoft any two of the moft learned moderns agree in their divifion of A- frica into kingdoms; and the reafon is, that fcarcely any traveller hath ever penetrated into thefe inhofpi- table regions, According to the beft accounts, con¬ cerning thofe regions of Africa lying beyond Egypt and Barbary, they are divided in the following man¬ ner. On the weftern coaft, to the fouth of Barbary, lie the kingdoms of Bildulgerid, Zaara, Negroland, Loango, Congo, Angola, Benguela, and Terra de Natal. On the eaftern coaft beyond Egypt, are thofe of Nubia, Adel, Ajan, Zanguebar (between thefe two a huge defart is interpofed), Monomatapa, and Sofola. In the interior parts, the kingdoms of Lower Ethiopia, Abex, Monemuge, and Matanan, are made mention of. The fouthermoft part, called Cafraria, is well known for the habitation of the Hottentots. In many material circumftances, the inhabitants of this extenlive continent agree with each other. If we except the people of Abyflinia, who are tawny, and profefs a mixture of Chriftianity, Judaifm, and Pagan- ifm, they are all of a black complexion. In their re¬ ligion, except on the fea-coafts, which have been vifi- ted and fettled by ftrangers, they are pagans; and the form of government is every where monarchical. Few princes, however, poflefs a very extenfive jurifdi&ion; for as the natives of this part of Africa are grofsly ig¬ norant in all the arts of utility or refinement, they are little acquainted with one another; and generally united in fmall focieties, each governed by its own prince. IntAbyfiinia, indeed, as well as in Congo, Loango, and Angola, we are told of powerful mo- narchs ^ but on examination, it is found that the au¬ thority of thefe princes Hands on a precarious foot- Afnw ing, each tribe or feparate body of their fubjedts being ' ' ~ v under the influence of a petty chieftain of their own, ftyled Negus, to whofe commands, however contrary to thofe of the Negafcha Negafcht, or king of kings, they are always ready to fubmit. The fertility of a country fo prodigioufly extenfive, might be fuppofed more various than we find it is : in fa6t, there is no medium in this part of Africa with regard to the advantages of foil; it is either perfectly barren or extremely fertile. This arifes from the in- tenfe heat of the fun ; which, where it meets with fuf- ficient moifture, produces the utmoft luxuriancy ; and in thofe countries where there are few rivers, reduces the furface of the earth to a barren fand. Of this fort are the countries of Anian and Zaara ; which, for want of water, and confequently of all other necefla- ries, are reduced to perfeft deferts, as the name of the latter denotes. In thofe countries, on the other hand, where there is plenty of water, and particularly where the rivers overflow the land part of the year, as in A- byffinia, the productions of nature, both of the animal and vegetable kinds, are found in the higheft perfec¬ tion and greateft abundance. The countries of Man- dmgo, Ethiopia, Congo, Angola, Batua, Truticui, Monomotapa, Cafati, and Mehenemugi, are extreme¬ ly rich in gold and filver. The bafer metals, likewife, are found in thefe and many other parts of Africa. But the perfons of the natives make the moft confider- able article in the produce and traffic of this miferable quarter of the globe. On the Guinea or weftern coaft, the Englifh trade to James Fort, and other fettlements near and up the river Gambia; where they exchange their woollen and linen manufactures, their hardware, and fpirituous li¬ quors, for the perfons of the natives. By the treaty of peace in 1783, the river of Senegal, with its de¬ pendencies, were given up to France. Gold and ivory, next to the flave trade, form the principal branches of African commerce. Thefe are carried on from the fame coaft, where the Dutch and French, as well as Englilh, have their fettlements for this purpofe. The Portuguefe are in pofleffion of the eaft and weft coaft of Afriba, from the Tropic of Capricorn to the Equator; which immenfe trad they became matters of by their fucceffive attempts and happy difeovery and navigation of the Cape of Good Hope. From the poaft of Zanguebar, on the eaftern fide, they trade not only for the articles abovementioned, but likewife for feveral others ; as fena, aloes, civet, ambergris, and frankincenfe. The Dutch have fettlements towards the fouthern part of the continent, in the country called Caffraria, or the land of the Hottentots, parti¬ cularly Cape Town, which is well fettled and fortified; where their Ihips bound for India ufually put in, and trade with the natives for their cattle, in exchange for which they give them fpirituous liquors. The Portuguefe being fovereigns of the greateft part of the coaft, have a number of black princes their tri¬ butaries. There arc fome independent princes who have extenfive dominions; particularly the kings of Dahome and Widah, the moft noted of any for the infamous flave trade. Upwards of 200 years have the European nations traded with Africa in human flelh ; and encouraged in the Negro countries, wars, rapine, F f 3 defolation.

Upon this lay more dung, about xo inches thick; then another layer of earth. Hill drawing in the fides of the bed, fo as to form it like the roof of a houfe; which may / be done by three layers of dung, and as many of earth. When the bed is finilhed, it muft be covered with litter or old thatch, both to prevent its drying too fall and to keep out wet. In this fituation it ought to remain eight or ten. days, when it wall be in a proper tempe¬ rature to receive the fpawn ; for this is deftroyed byi Agancss, too much heat; though, before planting, it may be kept' v very dry, not only without detriment, but with confi- derable advantage.—The bed being in a proper tem¬ perature for the fpawn, the covering of litter Ihould be taken off, and the fides of the bed fmoothed ; then a covering of light rich earth, about an inch thick, Ihould be laid all over the bed ; but this Ihould not be wet. Upon this the fpawn muft be thruft, laying the lumps two or three inches afunder: then gently cover this with the fame light earth, above half an inch thick; and put the covering of litter over the bed, lay¬ ing it fo thick as to keep out wet, and prevent the bed from drying. In fpring or autumn the muihrooms will begin to appear, perhaps in a month after making ; but when the beds are made in fummer or winter, they are much longer before they produce. In any feafon, however, they ought not to be haftily deftroyed ; fince mufhroom-beds have been known to produce very plentifully, even after the fpawn has lain in them five or fix months. When the beds are deftroyed, the fpawn fhould be carefully preferred,, and laid up in a dry place, at leaft five or fix weeks before it is again planted.—The difficulty of managing mufhrom-beds is, to keep them always in a proper degree of moifture. In the fummer feafon they may be uncovered to re¬ ceive gentle ffiowem of rain at proper times; and in long dry feafons the beds ffiould now and then be watered, but much wet ought by no means to be fuf- fered to come to them. During the winter feafon they muft be kept as dry as poffible, and fo clofely covered as to keep out cold. In frofty, or very cold weather, if fome warm litter, fhaken out of a dung-heap, is laid on, the growth of the muffirooms will be promoted : but betwixt this and the bed, a covering of dry litter muft be interpofed ; which Ihould be renewed as it de¬ cays ; and, as the cold increafes, the covering muft be thickened. By attending to thefe diredlions, plenty of muftirooms may be produced all the year round. One bed will continue good for many months. For a pe¬ culiar, perhaps fabulous, method of producing muffi¬ rooms, fee the article Lyncurius. Phyficians have difputed much about the qualities of muffirooms ; fome confidering them as a rich nou- riffiment, and perfectly innocent, when properly cho- fen ; and others afferting them to be extremely dele¬ terious. Moil of the fungi are indeed of a hurtful quality; and, with refpeft to the whole tribe, the ef¬ culent are very few. Efculent muffirooms are very nutritive, very readily alkalefcent, and more fo with¬ out intermediate acefcency than any other vegetable : they are therefore a, rich nouriffiment, and much akin to animal food; on which account they may be in¬ dulged in confiderable quantity to ftrong perfons. It requires, however, ikill to diftinguiih this efculent kind ; and very few, efpecially of thofe who are commonly employed to gather them, viz. the fervants, have ftu- died Clufius, or other authors who have been at the pains to diftinguiffi them. Perhaps our efculent muffi¬ rooms, if old, acquire a dangerous acrimony ; and for thefe reafons Dr Cullen is of opinion that it is for the moft part prudent to avoid them. In the warmer cli¬ mates they may be ufed as light food ; but here it is prepofterous to ufe them along with animal food, as they do not correct its alkaline tendency. AGATE,. f A G A [ 232 ] A G A ;Ag«e. AGATE, or Achat, (among the Greeks and La- tins, A^ar»c, and Achates, from a river in Sicily, on the banks of which it was firft found), a very extenlive ge¬ nus of the femipellucid gems. Thefe ftones are variegated with veins and clouds, but have no zones like thofe of the onyx. They are compofed of chryftal debafed by a large quantity of earth, and pot formed, either by repeated incruftations round a central nucleus, or made up of plates laid even¬ ly on one another; but are merely the effeft of one iim- ple concretion, and variegated only by the difpoiition given, by the fluid they were formed in, to their differ¬ ently coloured veins or matters. Agates are arranged according to the different co¬ lours of their ground. Of thofe with a •white ground there are three fpecies. (1.) The dendrachates, mocca jlone, or aborefcent a gat. This feems to be the fame with what fome authors call the achates with rofemary in the middle, and others achates with little branches of black leaves. (2.) The dull, milky-looking^ agate. This, though greatly inferior to the former, is yet a •very beautiful ftone. It is common on the fhores of rivers in the Eali Indies, and alfo in Germany and fome other parts of Europe. Our lapidaries cut it in¬ to counters for card-playing, and other toys of fmall value. (3.) The lead-coloured agate, called the phajfa- chates by the ancients. Of the agates with a reddijh ground there are four fpecies. (1.) An impure one of a flefli-coloured white, which is but of little beauty in comparifon with other agates. The admixture of flefli-colour is but very flight; and it is often found without any clouds, veins, or other variegations ; but fometimes it is prettily vein¬ ed or variegated with fpots of irregular figures, ha¬ ving fimbriated edges. It is found in Germany, Italy, and fome other parts of Europe ; and is wrought into ' toys of fmall value, and often into the German gun- flints. It has been fometimes found with evident fpeci- mens of the perfeft moffes bedded deep in it. (2.) That of a pure blood colour, called hcesnachates, or \dxe. bloody agate, by the ancients. (3.) The clouded and fpotted agate, of a pale flefli colour, called by the ancients the carnelian agate, or fardachates. 4. The red-lead-coloured one, variegated with yellow, called . the coral agate, or coraila-uchates, by the ancients. Of the agates with a yellonuijb ground there are on¬ ly two known fpecies; the one of the colour of yel¬ low wax, .called cerachates by the ancients ; the other a very elegant ftone, of a yellow ground, variegated with white, black, and green, called the leonina, and leonteferes by‘the ancients. Laftly, Of the agates with a greenijh ground, there is only one known fpecies, called by the ancients jaf~ 'pachates. Of all thefe fpecies there are a great many varieties ; fome-of them having upon them natural reprefentations of men and different kinds of animals, &c. Thefe reprefentations are not confined to the agates whofe ground is of any particular colour, but are occafional- ly found on all the different fpecies. Velfchius had in his culledy'a flefh-coloured agate, on one fide of which appeared a half-moon in great perfection, reprefented by a milky femicircle ; on the other fide, the phafes of vefper, or the evening-ftar; whence he denominated it an aphrod:Jian agate. An agate is mentioned by Kir- N3 6. cher *, on which was the reprefentation of a heroine Agate, armed; and one in the church of St "Mark in Venice " 1 has the reprefentation of a king’s head adorned with a German1* ^ diadem. On another, in the mufseum of the prince dec. i. an", r. of Gonzaga, was reprefented the body of a man with obf. 151, all his clothes in a running pofture. A ftift more cu¬ rious one is mentioned by de Boot f, wherein appears a | De Gem. i circle ftruck in brown, as exaftly as if done with a pairl. ii. c. 95. of compaffes, and in the middle of the circle the exaCt figure of a bifliop with a mitre on : but inverting the ftone a little, another figure appears ; and if it is turn¬ ed yet further, two others appear, the one of a man, and the other of a woman. But the moft celebrated agate of this kind is that of Pyrrhus, wherein were re¬ prefented the nine mufes, each with their proper attri¬ butes, and Apollo in the middle playing on the harp J;-. j pjjny. In the emperor’s cabinet is an oriental agate of a fur-!, xxxvii. ] prifing bignefs, being fafliioned into a cup, whofe dia-c- 3* meter is an ell, abating two inches. In the cavity is found delineated in black fpecks, b. xrtstor. s. xxx. Other agates have .alfo been found, reprefenting the numbers 4191, 191 ; whence they were called arithme¬ tical agates, as thofe reprefenting men or women have obtained the name of anthropomorphous. Great medicinal virtues were formerly attributed to the agate, fuch as “refifting poifons, efpecially thofe of the viper, fcorpion, and fpider ; but they are now very juftiy rejeCted from medicinal praClice. The oriental ones are all faid to be brought from the river Gambay. A mine of agates was fome time ago difeovered in Tranfylvania, of divers colours ; and fome of a large fize, weighing feveral pounds. Agates may be ftained artificially with folution of filver in fpirit of nitre, and afterwards expofing the part to the fun; and though thefe artificial colours difappear on laying the ftone for a night in aquafortis, yet a knowledge of the practicability of thus ftaining agates, muft render thofe curious figures above-men¬ tioned ftrongly fufpeCted of being the work not of na¬ ture, but of art. Some account for thefe phenome¬ na from natural caufes. Thus, Kircher, who had feen a ftone of this kind in which were depicted the four letters ufually inferibed on crucifixes, I. N. R. I. ap¬ prehends that fome real crucifix had been buried un¬ der-ground, amnog ftones and other rubbifti, where the infeription happening to be parted from the crofs, and to be received among a foft mould or clay fufceptible of the imprelfion of the letters, came afterwards to be petrified. In the fame manner he fuppofes the agate of Pyrrhus to have been formed. Others refolve much of the wonder into fancy, and fuppofe thofe ftones formed in the fame manner with the camieux * or Flo- • See Cc» j rentine ftones. mieux. The agate is ufed for making cups, rings, feals, han¬ dles for knives and forks, hilts for fwords and hangers, beads to pray with, fmelling boxes, patch-boxes, See. being cut or fawed with no great difficulty. At Paris, none have a right to deal in this commodity except the wholefale mercers and goldfmiths. The fword-cutlers are allowed to fell it, but only when made into handles for couteaux de chaffe, and ready fet in. The cutlers have the fame privilege for their knives and forks. Confiderable quantities of thefe ftones are ftill found near the river Achates in Sicily. There are found in fome of thefe the furprifing reprefentations above- men- A G A L 233 ] A G A Agate mentioned, or others fimilar to them. By a dexterous II management of thefe natural ftains, medals have been . ^at ias', produced, which feem mafter-pieces of nature: for this done bears the graver well; and as pieces of all mag¬ nitudes are found of it, they make all forts of work of it. The high altar of the cathedral of Meffina is all over encrutled with it. The lapidaries pretend that the In¬ dian agates are finer than the Sicilian; but Father La- ’ Voyage bat * informs us, that in the fame quarries, and even in <5 ItaL tom. tjje fam€ block, there are found pieces much finer than 1 v. p. 15 . ot}ierS) ancl thefe fine pieces are fold for Indian agates in order to enhance their price. Agate, among antiquaries, denotes a Hone of this kind engraven by art. In this fenfe, agates make a fpe- ciesof antique gems ; in the workmanfhip whereof we find eminent proofs of the great Ikill and dexterity of the fculptors. Several agates of exquifite beauty are preferved in the cabinets of the curious ; but the fadts or hiftories reprefented on thefe antique agates, however well executed, are now become fo obfeure, and their explications fo difficult, that feveral diverting miftakes and difputes have arifen among thofe who undertook to give their true meaning. 1 he great agate of the apotheofis of Auguftus, in the treafury of the holy chapel, when fent from Con- ftantinople to St Lewis, paffed for a triumph of Jofeph. An agate, now in the French king’s cabinet, had been IHift. Acad, kept yco years with great devotion, in the BenedidHne R.. Infcript, abbey of St Evre at Toul, where it paffed for St John ' :t0:: *_!_P the EVangelilt carried away by an eagle, and crowned ■335> by an angel; but the Heathenifm of it having been lately detefted, the religious would no longer give it a place among their relifts, but prefented it in 1684 to the king. The antiquaries found it to be the apo¬ theofis of Germanicus. In like manner the triumph of Jofeph was found to be a reprefentation of Germa¬ nicus and Agrippina, under the figures of Ceres and Triptolemus. Another was preferved, from time im¬ memorial, in one of the moft ancient churches of France, where it had paffed for a reprefentation of pa- radife and the fall of man ; there being found on it two figures reprefenting Adam and Eve, with a tree, a fer- pent, and a Hebrew infeription round it, taken from the third chapter of Genefis, “ The woman faw that the tree was good,” &c. The French academifts, in- ftead of our firft parents, found Jupiter and Minerva reprefented by the two figures: the infeription was of a modern date, written in a Rabbinical charafter, very incorreft, and poorly engraven. The prevailing opi¬ nion was,sthat this agate reprefented fimply the worlhip ef Jupiter and Minerva at Athens. .Agate, is alfo a name of an inftrument ufed by gold- v/irc-drawers; fo called from the agate in the middle of it, which forms its principal part. AGATHIAS, or, as he calls himfelf in his epi- grams, Agathius, diftinguifhed by the title of Scls- lajlicus, a Greek hiftorian in the 6th century under Ju- ftinian. He was born at Myrina, a colony of the an¬ cient JEolians, in Afia the lefs, at the mouth of the ri¬ ver Phythicus. He was an advocate at Smyrna. Tho’ he had a tafte for poetry, he was yet more famous for his hiftory, which begins with the 26th year of Jufti- nian’s reign, where Procopius ends. It was printed in Greek and Latin, with Bonaventure Vulcanius’s, at Vol. I. Part I. Leyden, 1594, in 4to; and in Paris at the king’s print- Agatho ing-houfe, 1660, in folio. II AGATHO, a tragic and comic poet, difciple to ■ g*ve' Prodicus and Socrates, applauded in Plato’s Dialogues for his virtue and beauty. His firft tragedy obtained the prize; and he was crowned in the prefence of upwards of 30,000 men, the 4th year of the 90th Olympiad. There is nothing now extant of his, ex¬ cept a few quotations in Ariftotle, Athenseus, and others. AGATHOCLES, the famous tyrant of Sicily, was fon of a potter at Reggio. He was a thief, a common foldier, a centurion, a general, and a pirate, all in a regular fucceffion. He defeated the Carthaginians fe¬ veral times in Sicily, and was once defeated himfelf. He firft made himfelf tyrant of Syracufe, and then of all Sicily; after which, he vanquifhed the Carthagi¬ nians again both in Sicily and Africa. But at length having ill fuccefs, and being in arrears with his foldiers, they mutinied, forced him to fly his camp, and cut the throats of his children, whom he left behind. Re¬ covering himfelf again, he relieved Corfou, befieged by Caffander; burnt the Macedonian fleet; returned to Si¬ cily; murdered the wives and children of thofe who had murdered his ; afterwards meeting with the foldiers themfelves, he put them all to the fword; and ravaging the fea-coaft of Italy, took the city of Hipponium. He was at length poifoned by his grandfon Archaga- thus, in the 72d year of his age, 290 years before Chrift, having reigned 28 years. AGATHYRNA, or Agathyrnum, Agathyr- sa, or Agathyrsum, (anc. geog.), a town of Sicily.; now 5 Marco; as old as the war of Troy, being built by Agathyrnus, fon of JEolus, on an eminence. The gentilitious name is Agathyrnxus; or, according to the Roman idiom, Agathyrnenjis. AGAVE, the common American aloe: A genus of the monogynia order, belonging to the hexandria clafs of plants; and in the natural method ranking under the xoth order, Corot;aria. The characters are : There is no calyx : The corolla is monopetalous and funnel- fliaped ; the border fix-parted, with lanced ereft divi- fions; The Jlamina confift of fix ereft filaments, longer than the corolla ; the antherae are linear, fliorter than the filaments, and verfatile : The piftillum is an oblong germen; the ftylus is filifonn, the length of the ftami- na, and triangular; the ftigma headed and triangular: The pericarpimn is an oblong triangular capfule, tri- locular and three-valved: The feeds are numerous. Of this genus, botanical writers enumerate eight fpecies. Of the Americana, or great American aloe, the ftems generally rife upwards of 20 feet high, and branch out on every fide towards the top, fo as to form a kind of py¬ ramid: the flender (hoots being garniftied with greenifh yellow flowers, which ftand ereft, and come out in thick clufters at every joint: thefe make a fine appearance, and continue long in beauty; a fucceffion of new flowers being produced for near three months in favourable feafons, if the plant is protefted from the autumnal colds. The feeds do not ripen in England. It has been generally thought, that thefe plants do not flower till they are 100 years old : but this is a miftake; for the time of their flowering depends on their growth : fo that in hot countries, where they grow fall, and ex- Gg pand AGE [ Adge, pand many leaves every feafon, they will flower , , few years ; but in colder climates, where their growth * 11 is flow, it will be much longer before they fhoot up their ftem. There is a variety of this fpecies with ftriped leaves, which are pretty common in the Englifh gardens. The other forts are fb tender, that they mull conilantly remain in the ftove. ADGE, a city of France, in Lower Languedoc, in the territory of Agadez, with a bifliop’s fee. The diocefe-is final!, but is one of the richeft countries in the kingdom.. It produces fine wool, wine, oil, corn, and filk. It is feated on the river Eraut, a mile and a _ quarter from'its mouth, where it falls into the gulph more properly denominated an iron than a golden age.. of Lyons, and where there is a fort built to guard its.

This period is fnppofed to have lafted till the expulfion of Saturn from his kingdom. The fiver age commen¬ ced when men began to deviate from the paths of vir¬ tue ;■ and in confequenee of this deviation, their lives - became lefs happy.. The brazen age commenced on a. farther deviation, and the iron age took place in confe-- quence of one Hill greater.—A late author, however, reflefting on the barbarifm of the firft ages, will have the order which the poets aflign to the four ages invert¬ ed ; the firft being a time of rudenefs and ignorance,, nient. The city is extended along the river, where it forms a little port, wherein fmall craft: may enter.- There is a great concourfe of pilgrims and other devout people to the chapel of Notre Dame de Grace. It is a little without the city, between which and the chapel there are about 13 or 14 oratories, which they vifit with naked feet. The convent of the Capuchins is well refted, on mount Ararat; whence men were faid to be defeended or fprung from mountains: or from Deu¬ calion and Pyrrha reftoring the -race of mankind, by throwing ftones .over thei-r heads. The northern poeta. alfo ftyle the fourth age of the world the ajhen-z'g^, from a Gothic king Madenis, or Mannus, who on account cf his great ftrehgth was-faid to be made of alh, or be- built, and on the outfide are lodgings and apartments caufe in his time people began to make ufe of weapons; for the pilgrims who come to perform their neuvaine made of that wood. or nine days devotion.. The chapel, which contains the image of the Vigin Mary, is diftin efent age, denotes all the fpace of time from Mofes to the coming of the Meffiah and, _ 3. The age to conte, denotes the time from the co¬ ming of the Meffiah to the. end of the world. Various other, divifions of the duration of the world into ages have been made by hiftorians.—The Sibyl¬ line oracles, wrote, according to fome, by Jews ac¬ quainted with the prophecies of the Old Teftament, divide the duration, of the world into ten ages; and ac • cording to Jofephus, each age contained fix hundred years. It appears, by Virgil’s fourth. eclogue, and other teftimonies,. that the age of Auguftus was repu- tion to the deluge which happened in . Greece during ted the end of thofe ten ages, confequentlyas the period the reign of Ogyges; this they called the obfeura uncertain age, becaufe the hiftory of mankind is alto¬ gether uncertain during that period. The fecond they call the fabulous or heroic age, becaufe it is the pe¬ riod in which the fabulous exploits of their gods and heroes are faid to have been performed. It began with the Ogygian deluge, and continued to the firft Olym¬ piad; where the third or hiftorical age commenced.— This divifion, however, it muft be obferved,,holds good only with regard to the Greeks and Romans, who had no hiftories. earlier than the firft Olympiad ; the Jews, of the world’s duration. By fome, the fpace of time commencing from Con- ftantine, and ending with the taking of Conftantinople by the Turks in the 15th century, is called the mid¬ dle, age: but others choofe rather to date the middle age from the divifion of the empire made by Theodo-- fins at the clofe of the 4th century, and extend it to the time of the emperor Maximilian I. in the begin- - ning of the 16th century, when tire empire was firft di¬ vided into circles.—The middle is by feme denoted the barbarous age, and the latter part of it the loivfl Some divide it into the non-academical zodL aca- Egyptians, Phenicians, and Chaldees,. not to mention age. the Indians and Chiriefe, who pretend to much higher, demical ages. The firft includes the fpace of time from. antiquity, are not included The interval fince the firft formation of man has been divided by the poets into four ages, diftinguiihed by the epithets of golden, fiver, brazen, and iron. During dot golden age, Saturn reigned in heaven, and juftice and innocence in this ..lower world. The, earth then the 6th to the 9th centuries, during which fchools o academies were loft in Europe. The fecond from the 9th century, when fchools were reftored, and univer ■ fities eftabliihed, chiefly by the care of Charlemagne. The feveral ages of the world may be reduced to three grand epochas, viz. the age of the law of nature, called b-y; AGE [ 235 1 AG E Age by tlie lews the void ape, from Adam to Mofes; the AGEMOGLANS, Agiamoglans, or At.amo- Agyt ” aSe the Jewifh law, from Mofes to Chrifl:; and the age of grace, from Chrift to the prefent year. Age is alfo frequently ufed in the fame fenfe with century, to denominate a duration of too years. Age likewife fignifies a certain period of the du» ration of human life : by fome divided into four ftages, namely, infancy, youth, manhood, and old age; the firft extending , to the 14th year, the fecond to the 25th, the third to the 50th, and the fourth to the end of lifeby others divided into infancy, childhood, youth, manhood, and old age. Age, in law, fignifies a certain period of life, when perfons of both fexes are enabled to do certain a&s. Thus, one at twelve years of age ought to take the oath of allegiance to the king in a leet; at fourteen he may marry, chufe his guardian, and claim his lands held in foccage. Twenty-one is called full age, a man or woman being then capable of afting for themfelves, of managing their affairs, making contradls, difpofing of their eftates, and the like. sIgf. of a Hsrfe. See Horse. jIge of Trees. Thefe after a certain age wafle. An oak at an hundred years old ceafes to grow. The tifual rule for judging of the age of wood, is by the number of circles which appear in the fubftance of a trunk or flock cut perpendicularly, each circle being fuppofed the growth of a year: though fome reject this method as precarious, alleging, that a fimple cir¬ cle is fometimes the produce of feveral years ; befides that, after a certain age, no new circles are formed. AaE-prler, in law, is when an adlion being brought againfl a perfon under age, for lands defcended to him, he, by motion or petition, fiiews the matter to the court, praying the adlion may be flaid till his full age, which the court generally agrees to. AGELNOTH, EgElnoth, or ^.thelnoth, in Latin Achelnotus, archbifhop of Canterbury, in the feign of Canute the Great, fucceeded Livingus in that fee in the year 1020. This prelate, firnamed the God, , was fon of earl Agilmer, and, at the time of his elec¬ tron, dean of Canterbury. After his promotion lie went to Rome, and received his pall from Pope Bene- dift VIII. In his way thither, as he paffed through Pavia, he purchafed, for an hundred talents of filver and one of gold, St Auguftin’s arm, which was kept there as a relic ; and fent it over to England as a pre¬ fent to Leofric earl of Coventry. Upon his return, he is faid to have raifed the fee of Canterbury to its for¬ mer In fire. He was much in favour with king Ca¬ nute, and employed his intereft with that monarch to good purpofes. It was by his advice the king fent over large fums of money for the fupport of the foreign churches’; and Mahnibury obfcrves, that this prince was prompted to afts of piety, and reftrained from ex- ceffes, by the regard he had for the archbifhop. Agel- hoth, after he had fat 17 years in the fee of Can- terbury, departed this life the 29th of October 1038, and was fucceeded by Eadfius, -king Harold's chap¬ lain.—This archbifhop was an author, having written, •i. A Panegyric on the blefled Virgin Maiy. 2. A Letter to Earl Leofric concerning St Auguftin. 3. Letters to federal perfons. AGEMA, in Macedonian antiquity, was a body of foldiery, not unlike the Roman legion. clans, in the Turkifh polity, are children purchafed ^jl11 from the Tartars, or raifed every third year, by way ^,r£1 of tribute, from the Chriflians tolerated in the Turkifh ’—-v- empire. Thefe, after being circumcifed and inilrudled in the religion and language of their tyrannical mailers, are learrit the exercifes of war, till they are of a pro¬ per age for carrying arms ; and from this corps the Ju- niffanes are recruited. With regard to thofe who are thought unfit for the army, they are employed in the lowell offices of the feraglio. Their appointments alfo are very fmall, not exceeding feven afpers and a half per day, which amount to about threepence-halfpenny of our money. AGEN, a city of France, on the river Garonne, the capital of Agenois in Guienne, and the fee of a bifhop. The gates and old walls, which are yet remaining, fhow that this city is very ancient, and that its former cir¬ cuit was not fo great as the prefent. The palace, wherein the prefidial holds his feffions at this day, was heretofore called the caftle of Montravel, and is feated without the walls of the old city, and on the fide of the fofle. There are likewife the ruins of another cattle called La Sagne, which was without the walls clofe by a brook.' Though the fituation of Agen is very convenient for trade and commerce, the inhabitants are fo very indolent that there is very little ; of which the neighbouring cities take the advantage. It is feat¬ ed on the bank of the river Garonne, in a pleafant country; but is itfelf a very mean and difagreeable place, the houfes being ill built, and the ftreets narrow, crook¬ ed, and dirty. E.

AGENDA, among philofophers and divines, figni¬ fies the duties which a man lies under an obligation to perform: thus, we meet with the agenda of a Chri- ftian, or the duties he ought to perform ; in oppofition to the credenda, or tilings he is to believe. Agenda, among merchants, a term lometimes ufed for a memorandum-book, in which is fet down all the bufinefs to be tranfacled during the day, either at home or abroad. Agenda, among ecclefiaftical writers, denotes the .fervice or office of the church. We meet with agenda matutina cS5 vefpertina, “ morning and evening pray¬ er's ;” agenda diet, “ the office of the day,” whether feaft or fail day ; agenda mortuorum, called alfo limply agenda, “ the fervice of the dead.” Agenda is alfo applied to certain church-books, compiled by public authority, preferibing the order and manner to be obferved by the minitters and peo¬ ple in the principal ceremonies and devotions of the church. In which fenfe, agenda amounts to the fame with what is otherwife called ritual, liturgy, acalou- thia, mijfal, formulary, directory. See.

The agentes in rebus, are by fome made fynonymous with our poft-mafters, but their funftions were of great extent. They correfpond to what the Greeks call ■nrvpvpopoi, and the Latins veredarii. There were various orders or degrees of agentes in rebus ; as, tribuni, pritnicerii, fenaieres, ducenarii, hi- archi, circitores, equites, tyrones, &c. through all which they rofe gradatim. Their chief, who refided at Con- ftantinople, was denominated princeps; which was a poll of great dignity, being reckoned on a level with the Thebans formed againft the Lacedaemonians had not obliged him to return home, he would have car¬ ried his victorious arms into the very heart of the Per- fian empire. He gave up, however, all thefe triumphs readily, to come to the fuccour of his country, which he happily relieved by his viftory over the allies in Bce- otia. He obtained another near Corinth ; but to his great mortification, the Thebans afterward gained fe- veral over the Lacedaemonians. Thefe misfortunes at firft raifed fomewhat of a clamour againil him. He had been fick during the firft advantages which the enemy gained ; but as foon as he was able to aft in perfon, by his valour and prudence he prevented the Thebans from reaping the advantages of their viftories; infomuch that it was generally believed, had he been in health at the beginning, the Lacedremonians would have fuftained no Ioffes, and that all would have been loft had it not been for his affiftance. It cannot be denied but he loved war more than the intereft of his country required; for if he could have lived in peace, he had faved the Lace- that of procunful. They were fettled in every part of daemonians feveral Ioffes, and they would not have been the empin preters. ; and are alfo faid to have ferved as inter¬ engaged in many enterprifes which in the end contri¬ buted much to weaken their power.

AGER picenus, or Picenum, (anc. geog.) a ter¬ ritory of Italy to the fouth-eaft of Umbria, reaching from the Apennine to the Adriatic. The people ; of his age, and 41ft year of his reign. Agefilaus would never fuffer any pifture or fculpture to be made of him, and prohibited it alfo by his will: this he is fuppofed to have done from a confcioufnefs of his own deformity; called Picentes (Cicero, Livy), diftinft from the Picen- for he was of a fhort ftature, and lame of one foot, fo tini on the Tufcan fea, though called by Greek writers nntsvTiMi. This name is faid to be from the bird Ficus, under whofe conduft they removed from the Sabines, of whom they were a colony. AGERATUM, bastard hemp-agrimony: Age- nus of the polygamia sequalis order, belonging to the fyngenefia clafs of plants; and in the natural method ranking under the 49th order, Compqfita difcoides. The charafters are : The common calyx is oblong, with ma¬ ny fcales. The compound corolla is uniform ; the co- rollets hermaphrodite, tubular, and numerous: the proper corolla is funnel-fhaped; the border 4-cleft, and expanded. The Jiamina confift of 5 capillary very Ihort filaments ; the anthera is cylindric and tubular. The pijiillum is an oblong germen ; with a filiform ftylus, and two flender ereft ftigmata. There is no pericar- pium; the calyx unchanged. The feeds are folitary, oblong, and angular. The receptaculum is naked, con¬ vex, and very fmall. Of this genus there are three Species / the conyzoides, the houftonianum, and the altiffimum. All thefe are natives of warm climates. The two firft are annual plants, and confequently can fee propagated only by feeds; which, however, come to perfeftion in this country. The third fpecies will that ftrapgers ufed to defpife him at the firft fight. His fame went before him into Egypt, and there they had formed the higheft idea of Agefilaus. When he landed in that country, the people ran in crowds to fee him but great was their furprife when they faw an ill-dreffed, flovenly, mean-looking little fellow lying upon the grafs; they could not forbear laughing, and applied to him the fable of the mountain in labour. He was, however, the firft to jeft upon his own perfon; and fuch was the gaiety of his temper, and the ftrength with which he bore the rougheft exereifes, that thefe qua¬ lities made amends for his corporal defefts. He was extremely remarkable for plainnefs and frugality in his drefsand way of living. “This ({ays Cornelius Nepos) is efpecially to be admired in Agefilaus: when very great prefents were fent him by kings, governors, and ftates, he never brought any of them to his own houfe ; he changed nothing of the diet, nothing of the apparel of the Lacedaemonians. He was contented with the fame houfe in which Eurifthenes, the founder of his fa¬ mily, had lived: and whoever entered there, could fee no fign of debauchery, none of luxury; but on the contrary, many of moderation and abftinence; for it was furn idl¬ ed in fuch a manner, that it differed in nothing from bear the fevereft cold of this country, but its feeds do that of any poor or private perfon.” Upon his arrival •4' into Egypt, all kind of provifions were fent to him but he chofe only the moft common, leaving the per¬ fumes, the confeftions, and all that was efteemed moft delicious, to his fervants. Agefilaus was extremely fond of his children, and would often amufe himfelf by- joining not ripen Ageratum, or Maudlin. See Achillea.

It is fituated under the meri¬ dian of London, in 6 degrees of N. lat. AGGER, in the ancient military art, a work of for¬ tification, ufed both for the defence and the attack of towns, camps, &c. In which fenfe it is the fame with what was otherwife called vallum, and in later times ag- gejlum; and among the moderns lines, fometimes cava¬ liers, terrajfes. See. The agger was ufually a bank, or elevation of earth or other matter, bound and fupport- ed with timber ; having fometimes turrets on the top, wherein the workmen, engineers, and foldiery, were placed. It was alfo accompanied with a ditch, which ferved as its chief defence. The ufual materials of which it was made were earth, boughs, fafeines, flakes, and even trunks of trees, ropes, &c. varioufly crofied, and interwoven fomewhat in the figure of ftars ; whence they were calledJle/lati axes. Where thefe were want¬ ing, ftones, bricks, tiles, fupplied the office : on fome occafions, arms, utenfils, pack-faddles, were thrown in to fill it up. We even read of aggers formed of the carcafes of the flain ; fometimes of dead bones mixed with lime ; and even with the heads of flaughtered ci¬ tizens. For want of due binding, or folid materials, aggers have fometimes tumbled down, with infinite mifehief to the men. The befiegers ufed to carry on a work of this kind nearer and nearer towards the place, till at length they reached the very wall. The methods taken, on the other fide, to defeat them, were by fire, efpecially if the agger were of wood ; by fap- ping and undermining, if of earth ; and, in fome cafes, by erecting a counter agger. The height of the agger was frequently equal to that ©f the wall of the place. Caefar tells us of one he made, which was 30 feet high and 330 feet broad. Befides the ufe of aggers before towns, the generals ufed to fortify their camps with fuch works ; for want of this precaution, armies have often been furprifed and ruined. There were vaft aggers made in towns and places on the fea-fide, fortified with towers, cattles, &c. Thofe made by Caefar and Pompey at Brundufium, are fa¬ mous. Sometimes aggers were even built acrofs arms of the fea, lakes, and morattes; as was done by Alex- der before Tyre, and by M. Antony and Caffius.— The wall of Severus, in the north of England, may be confidered as a grand agger, to which belong feveral letter ones. See SerERue’s Wall. Agger, in ancient writers, likewife denotes the middle part of a military road, raifed into a ridge, with a gentle flope on either fide, to make a drain for the water, and keep the way dry. The term is-alfo ufed for the whole road, or military way. Where highways were to be made in low grounds, as between two hills,, the Romans ufed to raife them above the adjacent land, fo as to make them of a level with the hills., Thefe banks they called aggeres. Ber- gier mentions feveral in Gallia Belgica, which were thus raifed ten, fifteen, or twenty feet above ground. —They are fometimes alfo called aggeres calceati; and now generally known by the name ebaujees, or caufe- Aggerhuys ways. - • H.

AGGLUTINANTS, in pharmacy, a general name for all medicines of a glutinous or vifeid nature; which, by adhering to the folids, contribute greatly to repair their lofs. AGGLUTINATION, in a general fenfe, denotes the joining two or more things together, by means of a proper glue or cement. Agglutination, among phyficians,. implies the action of reuniting the parts of a body, feparated by a wound, cut, See. It is alfo applied to the aftion of fuch internal medicines as are of an agglutinating qua¬ lity, and which, by giving a glutinous confiftence to the animal-fluids, render them more proper for nourifti- ing the body. AGGREGATE, in a general fenfe, denotes the fum of feveral things added together, or the collection of them into one whole. Thus, a houfe is an aggregate of ftones, wood, mortar, &c. It differs from a mixed or compound, inafmuch as the union of thefe laft is more intimate than between the parts of an aggregate. Aggregate, in botany, is a term ufed to exprefs thofe flowers, which are compofed of parts or florets; fo united by means either of the receptacle or calyx, that no one of them can be taken away without de- ftroying the form of the whole. They are oppofed to Ample flowers, which have no fuch common part, and are ufually divided into feven kinds, viz. the aggregate, properly fo called, whofe receptacle is dilated, and whofe florets are fupported by foot-ftalks ; fuch are the blue daify, thrift, or fea-pink, &c.; the compound; the umbellati ; the cymofe ; the amentaceous ; the glu* mofe ; and the fpadheous. AGGREGATION, in phyfics, a fpecies of union whereby feveral things which have no natural depen¬ dence or connection with one another are collected to¬ gether, fo as in fome fenfe to eonftitute one. Thus, a heap of fand, or a mafs of ruins, are bodies by aggre¬ gation. AGHER, a town of Ireland, which fends two mem¬ bers to parliament.

Aghrim, in Galway ; a fmall village, diftant.about 32 miles from Dublin, and rendered memorable by a decifive battle fought there, and at Kilcommodon-hili, the 1 2th of July 1691, between general Ginckle and Monfieur St Ruth, the commanders under king Wil ¬ liam III. and James II. when St Ruth, the general of the Irifli army, with 7000 of his men, were flain ; but of the Engliffi only 600. The vi&ory was the more confiderable, as the Englifli army, confifted of no more than 18,000 men ; whereas the Irifli were computed at 20,000 foot and 5000 horfe and dragoons.

AGILITY, an aptitude of the feveral parts of the body to motion.—The improving of agility was one of the chief objefts of the inftitution of games and exer- cifes. The athletse made particular profeffion of the fci- ence of cultivating and improving agility. Agility of body is often fuppofed peculiar to fome people; yet it feems lefs owing to any thing peculiar, in their frame and ftru&ure, than to practice. AGINCOURT, a village of the French Nether¬ lands, fituated in E. Long. 2. 10. N. Lat. 50. 35.; fa¬ mous on account of the vi&ory obtained by Henry V. of England over the French, in 1415. The army of Henry, after landing in France, was by various accidents reduced to 10,000 men, of whom not a few were fick, orflowly recovering fromficknefs; —they had to traverfe a long trail of country, inha¬ bited by exafperated enemies, from whom they were to procure provifions, lodgings, guides, intelligence, and every thing they wanted;—that country was de¬ fended by many ftrong towns, interfeiled by deep ri¬ vers, and guarded by an army of 100,000, or (accord¬ ing to fome contemporary writers) 140,000 men. Henry, undaunted by all thefe dangers and difficul¬ ties, departed from Harfleur, marching his army in three lines, with bodies of cavalry on the wings. He proceeded by very eafy journeys, that he might not fa- [ 238 1 A G I tigue his troops, or difcourage them by the appearance or ufc their arms ; and, in a -word, was the chief caufe Henry, with fdme of his bed officers, Carefully ex»- ^ mined the ground, and pitched upon a field of battle, admirably calculated to preferve a fmall army from be¬ ing furrounded by a great one. It was a gentle de¬ clivity from the village of Agrncourt, of fufficient ex¬ tent for his fmall army, defended on each fide by hedges, trees, and brulh-wood. Having placed guards and kindled fires on all fides, the king and his army betook themfelves to reft; except fuch as were of a more fe- rious turn of mind, and, confidering that as the laft night of their lives, fpent it in devotion. The French, exulting in their numbers, confident of ' victory, and abounding in provifions, fpent the night in noify feftivity, and in forming fanciful fchemes a- bout the difpofal of their prifoners and their booty. It was in general refolved to put all the Englifli to the fword, except the king and the chief nobility, who were to be taken prifoners for the fake of their ran- foms. On the morning oi Friday, the memorable 25th of OCtober, A. D. 14x5, the day of Crifpin and Crifpia- nus, the Englilh and French armies were ranged in or¬ der of battle, each in three lines, with bodies of cavalry on each wing. The Conftable D’Albert, who com¬ manded the French army, fell into the fnare that was laid for him, by drawing up his army in the narrow plain between the two woods. This deprived him, in a great meafure, of the advantage he fhould have de¬ rived from the prodigious fuperiority of his numbers ; obliged him to make his lines unneceflarily deep, about 30 men in file ; to crowd his troops, particularly his cavalry, fo clofe together, that they could hardly move of a flight; obferving the ftriCleft difcipline, and pay¬ ing generoufly for every thing he received'^ which in¬ duced the country people to bring provifions to his camp, in fpite of all the commands they had received to the contrary. To keep his men in fpirits, and from repining, the king fared as ill as the meaneft foldier, always appearing with a cheerful countenance, and ad- dreffing them in the me ft friendly and encouraging language. They arrived at the village of Agincourt, in the county of St Pol, on the evening of OClober of all the difafters that followed. The French, it i faid, had a confiderable number of cannon of different fixes in the field; but we do not hear that they did any execution, probably for want of room. The ftrft line of the French army, which confifted of 8000 men- at-arms on foot mixed with 4000 archers, with 500 men-at-arms mounted on each wing, was commanded by the Conftable D’Albert, the dukes of Orleans and Bourbon, and many other nobles ; the dukes of Alen- $on, Brabant, and Bar, &c. conduced the fecond line; 24th; and there beheld the whole French army, at a and the earls of Marie, Damartine, Fauconberg, &c. fmall diftance, diredtly in their route. The king took an attentive view of it from an eminence ; and being ■fully convinced that it was impoffible to proceed any further on his way to Calais without a battle, and e- qually impoffible to return-to Harfleur with fo great an mrmy in his rear, he refolved to hazard an aftion next were at the head of the third line. The king of Eng¬ land employed various arts to fupply his defeft of num¬ bers. He placed 200 of his heft archers in ambufh, in a low meadow, on the flank of the firft line of the French. His own firft line confifted wholly of archers, four in file ; each of whom, befides his how and ar- morning, as the only means of preferving himfelf and rows, had a battle-axe, a fword, and a ftake pointed ibis little army from deftruftion, The Englifh army lodged that night in the villages ■of Agincourt, Maifoncelle, and fome others; where sthey met with better accommodation than they had been accuftomed to for fome time part, and fpent part of their time in mutual exhortations to fight bravely in with iron at hot’ll ends, which he fixed before him in the ground, the point inclining outwards, to protect him from cavalry; which was a new invention, and had a happy effect. That he might not be encumbered, he difmuTed all his prifoners, on their word of honour to furrender themfelves at Calais, if he obtained the vio the approaching battle. The king, overhearing fome tory; and lodged all his baggage in the village of A- of bis nobles expreffing a wifh that the many brave ginCourt, in his rear, under a flender guard.

The lines being 1 formed, the king, in fhining armour, with a crown of gold adorned with precious ftones on his helmet, mount- ed on a fine white hor-fc, rode along them,, and addref- fed each corps with a cheerful countenance and ^ani¬ mating fpeeches. To inflame their refentment againit their enemies, he told them, that the French had de¬ termined. to cut off three fingers of the right hand of every prifoner ; and to roufe their love of honour, he declared, that every foldier in that army who behaved well, fhou'ld from henceforth be deemed a gentleman, and intitled to bear coat-armour. When the two armies were drawn up in this man* ner, they flood a coniiderable time gazing at one ano¬ ther in folemn filence. But the king, dreading that the French would diicover the danger of their iituation and decline a battle, commanded the charge to be founded, about ten o’clock in the forenoon. At that inflant, the firfl line of the Englifh kneeled down,, and killed the ground ; and then flailing up, difehar- ged a flight of arrows,, which did great execution a- along the crowded ranks of the French- Immediate¬ ly after, upon a fignal being given, the archers in am- bulh a role, andMifcharged their arrows on the flank of the French line, and threw it into fome diforder. The battle now became general, and raged with uncommon fury. The Engliflt archers, having expended all their arrows, threw away their bows, and, rulhing forward, made dreadful havoc with their fwords and battle-axes. The firll line of the enemy was, by thefe means, de¬ feated ; its leaders being either killed or taken prifon- ers. The fecond line, commanded by the duke D’A- len5on, (who had made a vow either to kill or take the king of England, or to periih in the attempt), now advanced to the charge, and was encountered by the. fecond line of the Ehglilh, conduced by the king- This conflict was more clofe and furious than the for¬ mer. Tire duke of Gloucefter, wounded and unhorfed, was protected by his royal brother till he was earned’ off the field. The duke D’Alen$on forced his way to the king, and aflaulted him with great fury ;. but that, prince brought him to the ground, where he was in* ftantly difpatcbed. Difcouraged by this difafter, the fecond line made-no more refiflance; and the third fled without ttrikmg a blow; yielding a complete and glo¬ rious victory to the Eugliih, after a violent ftruggle of three hours duration.. The king did not permit his men to purfue the fu-* gitivesvto a great diftance, but encouraged them to take as many pi ifoners as they could on or near the field ; in which they were fo fuccefsful, that, in a little time, , Kis captives were more numerous than his foldiers. A great proportion of thefe prifoners-were men of rank and fortune ; for many of the French nobleffe being- on foot, and loaded with their heavy armour, could not make their efcape. Among thefe were the dukes of ©rleans and Bourbon, the marflial Boueicaut, the counts D’Eu, Vendome, Richemont, and Harcourt, and 7000 barons, knights, and gentlemen. The French left dead on the field of battle, the conftable D’Albert, the three dukes of Alenpon, Brabant, and Bar, the arehbifhop of Sens, one marftial, 13 earls, 92 barons, 1500 knights, and a far greater number of gentlemen, befides feveral thoufands of common foldiers. Even the French hi- ftorians acknowledge, that, the lofs of the Engliffi 1r was inconfiderable: thofe of our own contemporary Agio writers who make it the greateft, affirm, that it did not exceed 100, and that the duke of York and the earl, y ' of ‘Suffolk were the only great men who fell on that fide in this memorable action. AGIO, in commerce, is a term chiefly ufed in Hol¬ land, and at Venice, to fignify the difference between the value of bank-flock and the current coin. The agio in Holland is generally three or four per cent. and at Rome it is from 15 to 25 jkr cent, but at Venice the agio is fixed at 20 per cent.

Agefilaus II. in a right line, fie projefted the re¬ formation of ~his kingdom, by the rettoring of the laws of Lycurgus ; but he fell under the weight of an en- terprife that could not but be difagreeable to all thofe who had great poffeffions, and had been long accuftom- ed to the iweets of a voluptuous life. Agis being in. the flower of his age, and having a very refined defire of glory, praffifed the ancient difeipline firft in his own perfon: his clothes, and his table were accord¬ ing to the manners of former times which is fa much the more to be admired, becaufe Agefiftrata his mother and Archidamia his grandmother had brought him up voluptuoufly. When he founded his peoples minds, he found the younger fort oppo- fed his project lefs than thofe who had enjoyed a relaxation, of difeipline feveral years. The greateft: difficulty was expedted to arife from the women. They had at that time more credit than ever ; for their power is never greater than when luxury is in faflrion*. Agefilaus’s. mother did not at all relilh the propo- fed reformation. She muft'have loft her riches, which, gave her a ihare in a thoufand forts of intrigues ; fo ftie oppofed the defign at once, and treated it as a chimera. But her brother Agefilaus, whom Agis had engaged in his interefts, knew how to manage her in fucli a manner that flie promifed to fecond the enter- prife. She endeavoured to gain the women : but in— ftead of fuffering thcmfelves to be perfuaded, they ap¬ plied to Leonidas the other king of Lacedaemon, and; humbly befought him to fruftrate the defigns of his- colleague. Leonidas durft'not oppofe it openly, for- fear of irritating the people ; to whom the reforma¬ tion was agreeable, beeaufe they found their account in it. He contented himfelf'with countermining it by intrigues, and fowing fufpicions as if Agis had afpired to tyranny, by pulling down the rich and raifing the poor. . Agis did not fail to propofe his new laws to - the fenate, relating to the difeharge of debts, and a. new divifion of the lands. Leonidas, being fupported1 by the rich, oppofed this projetft fo ftrongly, that there, was one voice more againft it than for it. He paid: dear for the fuccefs in this affair. Lyfander, - one of the Ephori, who had been the grand promoter of the reformation, called him to account; alleged the celeftiaF figns; and put to death Cleombrotus,a princeof the royal: blood and fon-in-law to Leonidas, to make fure of the kingdom.

He was fummoned ; and becaufe he did not appear, he was degraded of his dig¬ nity, which was conferred on Cleombrotus. He ob¬ tained leave to retire to Tegsea. The new Ephori had Lyfander and Mandroclidas tried for innovation : thefe perfuaded the two kings to unite and turn out thefe Ephori. The thing was brought about; but not with¬ out a great uproar in the city. Agefilaus, one of the Ephori that Succeeded thofe who were juft turned out, would have caufed Leonidas to be killed on the way to Tegsea, if Agis had not fcnt him a ftrong guard, [ 240 ] A G M The reformation might then have been eftablifhed, if tation of the particles. and are created by letters-patent.

At his return, he found his affairs fo embroiled by the ill conduft of Ag'efilaus, that it was impoffible for him to maintain himfelf.

K . ... . J . . . r . _ . Lett. tom. banilhing his fon-in-law; after which he applied him- people into trembling and agitations, and unlefs they ^ felf entirely to the ruin of Agis. One of the Epk who had no mind to return what Agefiftrata had lent him, was the principal inftrument of the misfortune of this family. Agis never went out of his fanftuary but to bathe. One day, as he was returning from thence to the temple, he was feized by that Ephorus and carried to prifon. Then he was brought to his got away betimes, fet them a dancing, with ftrange contortions and gefticulations. This leems to verify what has been related of the temple of Delphi. Agitation is alfo ufed in medicine for a fpecies of exercife popularly calledfwinging. Maurice prince of Orange found this method a relief againft the fevere pains of the gout and ftone. Bartholine mentions fits trial and condemned to death, and delivered to the of the toothach, deafnefs, &c. removed by vehement executioner. His mother and grandmother ufed all agitations of the body. the intreaty and importunity imaginable, that, as he was king of Lacedsemon, he might at leaft be permit¬ ted to, plead his caufe before the people. But they were apprehenfive left his words would make too great an impreffion, and therefore they ordered him to be ftrangled that very Four. The Ephorus who was in debt to Agefiftrata permitted that princefs to go into th« prifon ; which he granted likewife to Agis’s grand¬ mother^ but he gave orders to ftrangle them one after another. Agefiftrata died in a manner that was ex¬ tremely to her honour. The wife of Agis, who was a princefs of great fortune and prudence, and one of the fineft ladies in Greece, was forced away from her apartment by king Leonidas, and obliged to marry his fon, who was then very young, and hardly fit for mar¬ riage. AGISTMENT, Agistage, or Agistation, in law, the taking in other people’s cattle to graze at fo much per week. The term is peculiarly ufed for the Liking cattle to feed in the king’s forefts, as well as for the profits arifing from that praftice.—It is alfo ufed, in a metaphorical fenfe, for any tax, burden, or AGITATOR, in antiquity, a term fometimes ufed for a charioteer, efpecially thofe who drove in the cir¬ cus at the curule games. Agitators, in the Englifii hiftory, certain officers fet up by the army in 1647, to take care of its inte- refts.—Cromwell joined the agitators, only with a view to ferve his own ends; which being once accompliftied, he found means to get them aholiftied. AGLAIA, the name of the youngeft of the three Graces, efpoufed to Vulcan. AGLIONBY (John), an Englilh divine, chaplain in ordinary to king James I. a man of univerfal learn¬ ing, who had a very confiderable hand in the tranfla- tion of the NewTeftament appointed by king James I. in 1604. AGMEN, in antiquity, properly denotes a Roman army in march: in which fenfe, it Hands contradi- ftinguiftied from acies, which denoted the army in bat¬ tle array; though, on fome occafions, we find the two words ufed indifferently for each other. The Roman armies, in their marches, were divided into prirnum ag- men, anfwering to our vanguard ; medium agmen, our change ; thus, the tax levied for repairing the banks of main-battle ; and poftremum agmen, the rear-guard. Romney-marfn was called agiftamentum. The order of their march was thus : After the firft fig- AGISTOR, or Agistator, an officer belonging fial with the trumpets, &c. the tents were taken down, to forefts, who has the care of cattle taken in to be and the baggage packed up ; at the fecond fignal, the grazed, and levies the moneys due on that account, baggage was to be loaden on the horfes and carriages ; The -, are generally called quejl-taken or gift-takers, and at the third fignal, they were to begin their march. .N° 6. - 3 Fir.it A G N [ 241 ] AGO Agrate Flrfl; came the extras din aril; then the auxiliaries of If the firft wing, with their baggage ; thefe were follow- .^nils' , ed by the legions. The cavalry marched either on each fide or behind. AGNATE, in law, any male relation by the fa¬ ther’s fide. AGNEL, an ancient French gold Coin, firft ftruck Under the reign of St Louis, worth about twelve fols fix deniers. The agnel is alfo called fometimes mouton d’nr, and agnel d’or. The denomination is fuppofed to have arifen from the figure of a lamb, agnus, or Iheep, ftruck on one fide. AGNO, a river of Naples, which, taking its rife in the mountainous parts of Terra di Lavoro, wafhes the town of Acerra ; and, palling between Capua and Averfa, falls into the Mediterranean, about feven miles north of Puzzuoli. AGNOETiE (from to be ignorant of), in church-hiftory, a feet of ancient heretics, who main¬ tained that Chrift, confidered as to his human nature, was ignorant of certain things, and particularly of the time of the day of judgment. Eulogius, patriarch of Alexandria, aferibes this herefy to certain folitaries in the neighbourhood of Jerufalem, who built their opi¬ nion 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 fame palfage was made ufe of by the Arians; and hence the orthodox divines of thofe days were induced to give various explications thereof. Some allege, that' our Saviour here had no regard to his divine nature, but only fpoke of his human. Others underftand -it thus, That the knowledge of the day of judgment does not concern our Saviour confidered in his quality of Meffiah, but God only: which is the molt natural folution. AGNOMEN, in Roman antiquity, a kind of fourth or honorary name, given to a perfon on account of fome extraordinary adlion, virtue, or other accomplifti- ment. Thus the agnomen jdfricamu was bellowed upon Publius Cornelius Scipio, on account of his great atchievements in Africa.—The agnomen was the third in order of the three Roman names : thus, in Marcus Tullius Cicero, Marcus is the prosnomen, Tullius the nomen, and Cicero the agnomen. AGNUS, or Lan(b, in zoology, the young of the ovis or Iheep. See Ovis. jdaNvs Cajlus, in botany, the trivial name of a fpe- oies of the vitex. See Vitbx. The Greeks call it «>'v©q chafle; to which has fince been added the re¬ duplicative cajlus, q. -d. chafte chafte. It was famous among the ancients as a fpecific for the prefervation of chaftity. The Athenian ladies, who made profeffion of chaftity, lay upon leaves of agnus cajlus during the feafts of Ceres.—Being reputed a cooler, and parti¬ cularly of the genital parts, it was anciently ufed in phyfic to allay thofe inordinate motions arifing from feminai turgefcences: but it is out of the prefent praTice. Avkus Dei, in the church of Rome, a cake of wax ftamped with the figure of a lamb fupporting the ban¬ ner of the crofs. Thefe being confecrated by the pope with great folemnity, and diftributed among the people, are fuppofed to have great virtues ; as, to pre- ferve thofe who carry them worthily, and with faith, Vol.L Part I. from all manner of accidents ; to expel evil fpirits, 8cc. Agnus • The name literally fignifies Lamb of God; this being II fuppofed an image or reprefentation of the Lamb of. g"na s*. God who took away the fins of the world. They co¬ ver it up with a piece of ftuff cut in form of a heart, and carry it very devoutly in their proceffions.—The Romilh priefts and religious derive confiderable pecu¬ niary advantage from felling thefe Agnus Dei's to fome, and prefenting them to others. The pope provides a regular fupply, by confecrating once in feven years; they are diftributed by the mafter of the wardrobe, and received by the cardinals and other prelates, with great reverence, in their caps and mitres.—This cere¬ mony they pretend to derive from an ancient cuftom of the church, wherein part of the pafchal taper con¬ fecrated on Holy Thurfday was diftributed among the people, to perfume their houfes, fields, See. in order to drive away devils, and to preferve them from ftorms and tempefts. The Agnus Dei is forbidden to be brought into England under pain of incurring a pre- munire; 13 Eliz. cap. 2. Agnus Dei is alfo a popular name for that part of the mafs wherein the prieft, ftriking his breaft three, times, rehearfes, with a loud voice, a prayer beginning with the words Agnus Dei.—The Agnus Dei is faid to have been firft brought into the miffal by pope Ser¬ gius I. Agnus Scythicus. See Scythian Lams. AGOGE, among ancient muficians, a fpecies of modulation, wherein the notes proceed by contiguous degrees. AGON, among the ancients, implied any difpute or conteft, whether it had regard to bodily exercifes or the accomplifhments of -the mind; and therefore poets, muficians, painters, Sec. had their agones, as well as the athletae. Games of this kind were celebra¬ ted at moft of the heathen feftivals, with great folemnity, either annually, or at certain periods of years. Among the latter were celebrated at Athens, the agongymnicus, the agon nemeus inftituted by the Argives in the 53d Olympiad, and the agon Olympias inftituted by Her¬ cules 430 years before the firft Olympiad.—The Ro¬ mans alfo, in imitation of the Greeks, inftituted contefts of this kind. The emperor Aurelian eftablifhed one under the name of agon folis, the conteft of the fun ; Dioclefian another, which he called agon capitolinus, which was celebrated every fourth year, after the man¬ ner of the Olympic games. Hence the years, inftead of lujlra, are fometimes numbered by agones. Agon alfo fignified one of the minifters employed in the Heathen facrifices, and whofebufinefs it was to ftrike the viftim. The name is fuppofed to have been derived from hence, that Handing ready to give the ftroke he allied, Agon' ? or A gone? Shall I ftrike? AGONALES, an epithet given to the Salii. AGONALIA, in Roman antiquity, feftivals ce¬ lebrated in honour of Janus, or the god Agonius, whom the Romans invoked before undertaking any affair of importance. AGONALIS circus, now La Piazza Navona, a long, large, beautiful ftreet in the heart of Rome, adorned with fountains, and the obelilk of Caracalla, ft ill retaining the form of that circus. The reafon of the name Agonalis is either unknown or doubtful. Ovid feems to derive it from the agones, or folemn games, H h there AGO [ 242 ] A G R Agonifma there celebrated; fuppofed to have been the Ludi Apol- II tinarss, or Aftiaci, inftituted by Auguftus : whence the circus was called Ap Alinaris ; alfo Alexandrinus, W—y—from the emperor Alexander Severus, who either en- clofed or repaired the circus. AGONISMA, in antiquity, denotes the prize given to the viftor in anv combat or difpute. AGONISTARCHA, from combat,” and “ chief,” in antiquity, feems to have been much the fame with agomtheta; though fome fuggeft a dif¬ ference, making it the office of the former to prefide at and direft the private exercifes of the athletic, which they went through by way of practice, before they made their appearance on the public theatres or am¬ phitheatres. AGONISTICI, in church-hiftory, a name given by Donatus to fueh of his difciples as he fent to fairs, markets, and other public places, to propagate his do&rine ; for which reafon they were alfo called Cir- cuitores, Circelliones, Catropitte, Coropitce, and at Rome Montenfcs. They were called Agonijfici, from the Greek eyov, “ combat,” in regard they were fent as it were to fight and fobdue the people to their opinions. AGONIUM, in Roman antiquity, was ufed for the day on which the rex facromm facrificed a victim, as well as for the place where the games were celebrated, otherwife called agon. AGONOTHETA, or Agonothetes, in Grecian antiquity, was the prefident or fuperintendant of the facred games; who not only defrayed the expences at¬ tending them, but infpe&ed the manners and difcipline of the athletse, and adjudged the prizes to the victors. AGONY, any extreme pain. It is alfo ufed for the pangs of death. Much of the terror of death con- fifts in the pangs and convulfions wherewith the agony feems attended; tho’ we have reafon to believe that the pain in fuch cafes is ordinarily not extremely acute; a courfe of pain and ficknefs having ufually ftupified and indifpofed the nerves for any quick fenfations. However, various means have been thought of for mi¬ tigating the agony of death. Lord Bacon confiders this as part of the province of a phyfician; and that not only when fuch a mitigation may tend to a reco~ very, but alfo when, there being no further hopes of a recovery, it can only tend to make the paflage out of life more calm and eafy. Complacency in death, which Auguftus fo much defired, is certainly no fmall part of happinefs. Accordingly the author laft cited ranks euthanajia, or the art of dying eafily, among the de- fiderata of fcience ; and does not even feem to difap- prove of the courfe Epicurus took fur that end, Hinc Jtygias ebrius haujit aquas. Opium has been applied for this purpofe, with the ap- plaufe of fome, but the condemnation of more. AGONYCLITzE, or Agonyclites, in church- hiftory, a fefl of Chriftians, in the 7th century, who prayed always ftanding, as thinking it unlawful to kneel. AGORzEUS, in heathen antiquity, an appellation given to fuch dieties as had ftatues in the market¬ places ; particularly Mercury, whofe ftatue was to be £een in almoft every public place. AGORANOMUS, in Grecian antiquity, a magi- ftrate of Athens, who had the regulation of weights and meafures, the prices of provifions, &c.—-The aoo- ranomi, at Athens, were ten in number, five belong- Ageuti ing to the city, and as many to the Piraeus ; though (I others make them fifteen in all, of whom they affign . gr‘cna,i ten to the city. To thefe a certain toll or tribute was paid, by all who brought any thing to fell in the market. AGOUTI, or Agutj. See Mus. AGRA, the capital town-of a province of the fame name, in Indoftan, and in the dominions of the Great Mogul. It is looked upon as the largeft eity in thefe parts, and is in the form of a half-moon. A man on j horfeback can hardly ride round it in a day. It is fur- rounded with a wall of red ftone, and with a ditch roo feet wide. The palace isprodigioufiy large, and the fera- glio commonly contains above 1000 women. There are upwards of 8oo baths in this town ; but that which travellers moft admire, is the maufoleum of one of the Mogul’s wives, which was 20 years in building. The indigo of Agra is the moft valuable of all that comes from the Eaft Indies. This town is feated on the river Jemma, about 50 miles above its confluence with the Tehemel, and is 300 miles N. E. of Surat. E. Long. 79. 12. N. Lat. 26. 29. AGRARIAN laws, among the Romans, thofe relating to the divifion and diftribution of lands ; of which there were a great number; but that called the Agrarian Law, by way of eminence, was publifhed by Spurius Caffius, about the year of Rome 268, for di¬ viding the conquered lands equally among all the citi¬ zens, and limiting the number of acres which each citizen might enjoy.—The Roman lands were of feve- ral kinds ; fome conquered from the enemies, and not yet brought to the public account; others brought in¬ deed to the public, but clandeftinely ufurped by pri¬ vate great men; laftly, others purchafed with the public money, in order to be divided. Agrarian laws, either for dividing lands taken from the enemy, or the public lands, or thofe purchafed with the public mo¬ ney, were eafily palled without difturbance ; but thofe whereby private rich men were to be deprived of their lands, and the common people put in poffeffion of what had been held by the nobility, were never at¬ tempted without great difturbances. Several have pleaded for the neceffity of agrarian laws among us: but no author has entered fo deeply into the fubjedt as Mr Harrington in his Oceana; which the reader who choofes may confult. AGREDA, a town of Spain, in Old Caftile, near the frontiers of Arragon, and about three leagues fouth-weft of Taracon. , AGRIA, called by the Germans Eger, is a fmall but ftrong town in Upper Hungary, and is a bilhop’s fee. It is fituated on a river of the fame name, and has a citadel called Eriaw. It was befieged by the Turks in 1552, with 70,000 men: but they loft 800a in one day; and were obliged to raife the fiege, though the garrifon confifted only of 2000 Hungarians, affift- ed by the women,, who performed wonders on this occafion. However, it was afterwards taken by Ma¬ homet III. in 1596 ; but was retaken by the emperor in 1687 ; fince which time it has continued under the dominion of the houfe of Auftria. It is 47 miles north- eaft of Buda, and 55 fouth-weft of Caflbvia. E. Long. 20. 10. N. Lat. 48. 10. AGRICOLA (Cneus Junius), born at Frejus in I. Pjro- A G R [ 243 ] A G R Agricola. Provence, was, in Vefpafian’s time, made lieutenant to ■' Vettius Bolanus in Britain; and, upon his return, was ranked by that emperor among the patricians, and made governor of Aquitnoia. This poll he held three years; and upon his return was chofen counfel, and after¬ ward appointed governor of Britain, where he greatly riiitinguifhed himfelf. He reformed many abufes oc- caiioned by the avarice or negligence of former gover¬ nors, put a flop to extortion, and caufed juftice to be impartially adminiftered. Vefpafian dying about this time, his fon Titus, knowing the great merit of Agri¬ cola, continued him in the government. In the fpring, he marched towards the north, where he made fome new conquefts, and ordered forts to be built for the Romans to winter in. He fpent the following win¬ ter in concerting fchemes to bring the Britons to con¬ form to the Roman cuftoms. He thought the belt way of diverting them from rifing and taking arms, was to foften their rough manners, by propofmg to them new kinds of pleafure, and infpiring them with a cklke of imitating the Roman manners. Sopn after this, the country was adorned with magnificent temples, porti¬ cos, baths, and many other fine buildings. The Britifli nobles had at length their fons educated in learning; and they who before had the utmoft averfion to the Roman language, now began to ftudy it with great affiduity: they wore likewife the Roman habit; and, as Tacitus obferves, they were brought to confider thofe things as marks of politenefs, which were only fo many badges of flavery. Agricola, in his third campaign, advan¬ ced as far as the Tweed; and in his fourth, he fub- dued the nations betwixt the Tweed and the friths of Edinburgh and Dumbritton, into which the rivers Glotta and Bodotria difcharge themfelves; and here he built fortrefles to ftiut up the nations yet unconquered. In his fifth, he marched beyond the friths; where he made fome new acquifitions, and fixed garrifons along the weftern coafts, over againft Ireland. In his fixth campaign he palled the river Bodotria, ordering his fleet, the firfl which the Romans ever had in thofe parts, to row along the coalts, and take a view of the northern parts. In the following fpring, the Britains raifed an army of 30,000 men; and the command, was given to Galgacus, who, according to Tacitus, made an excellent Ipeech to his countrymen on this occafion. Agricola likewife addrelfed his men in very ftrong and eloquent terms. The Romans gained the vidtory, and 16,000 of the Britains are faid to have been killed. This happened in the reign of the emperor Domitian; who, growing jealous of the glory of Agricola, recal¬ led him, under pretence of making him governor of Syria. Agricola died foon after; and his death is fufpefted to have been occafioned by poifon given him by that emperor. Tacitus the hiilorian married his daughter, wrote his life, and laments his death in the molt pathetic manner. Agricola (George), a German phyfician, famous Agricola, for his Ikill in metals. He was born at Glaucha, 1— in Mifnia, the 24th of March 1494. The difcoveries which he made in the mountains of Bohemia, gave him fo great a defire of examining accurately into e- very thing relating to metals, that though he had en¬ gaged in the practice of phyfic at Joachimltal by ad¬ vice of his friends, he Hill profecuted his Itudy of fof- fils with great affiduity; and at length removed to Chemnitz, where he entirely devoted himfelf to this Itudy. He fpent in purfuit of it the penfion he had of Maurice duke of Saxony, and part of his own eftate ; fo that he reaped more reputation than profit from his labours. He wrote feveral pieces upon this and other fubjedts; and died at Chemnitz the 2 ill of November 1555, a very firm Papill. In his younger years he feemed not averfe to the Protellant dodtrine ; and he highly difapproved of the fcandalous traffic of indul¬ gences, and feveral other things in the church of Rome. The following lines of his were polled up in the llreets of Zwickaw, in the year 1719 : Si nos inje&o fal-oebit ciftula nummo, Heu mmium iifdix tu mihi, pauper, eris ! Si not, Chrijlt, tua feruatos morte beafti, T:m nihil infelix tu mihi, pauper, eris. If wealth alone falvation can procure, How fad a (late for ever waits the poo." ! But if thou, Chrift, our only faviour be, Thy merits Hill may blefs ev’n poverty ! In the latter part of his life, however, he had attacked the Protellant religion : which rendered him fo odious to the Lutherans, that they fuffered his body to remain unburied for five days together; fo that it was obliged to be removed from Chem¬ nitz to Zeits, where it was interred in the principal church. Agricola (John), a Saxon divine born at Mebe in 1492. He went as chaplain to count Mansfield, when that nobleman attended the Eledlor of Saxony to the diet of Spire in 1526, and that of Aulburg in 1530. He was of a reltlefs ambitious temper, rivalled and wrote againll Melandllion, and gave count Mansfield occafion to reproach him feverely. He obtained a pro- felforlhip at Wittemberg, where he taught particular dodlrines, and became founder of the fedt of Antino- mians; which ©ccafioned warm difputes between him and Luther, who had before been his very good friend. But though he was never able to recover the favour ei¬ ther of the eledlor of Saxony or of Luther, he recei¬ ved fome confolation from the fame he acquired at Ber¬ lin ; where he became preacher at court; and was cho¬ fen in 1548, in conjundlion with Julius Phlug and Michael Heldingus, to compofe the famous Interim, which made fo much noife in the world. He died at Berlin in 1566. AGRICULTURE Definition. /T AY be defined, The art of difpofing the earth in by this definition, agriculture, llriclly fpeaking, includes J_VJl Inch a manner as to produce whatever vegetables in it the cultivation of every fpecies of vegetable what- we defire, in large quantity, and in the greatell perfec- ever, and confequently comprehends all that is under- tion of which their natures are capable.—But though, Hood of gardening and. planting, we mean here to con- H h 2 fine fine ourfelves to the cultivation of thofe fpecies of grain, grafs, See. which, in this country, are generally ne- ceffary as food for men and beafts. History. The antiquity of this art is undoubtedly beyond that of all others; for we are informed by Scrip¬ ture, that Adam was feat from the garden of Eden to till the ground; and, this being the cafe, he certain¬ ly muft have known how to do fo.—It would be ridi¬ culous, however, to imagine that he was acquainted with all the methods of ploughing, harrowing, fallow¬ ing, &c. which are now made ufe of; and it would be equally fo to fuppofe, that he ufed fuch clumfy and unartful inftruments as wooden hooks, horns of oxen, &c. to dig the ground, which were afterwards employ¬ ed for this purpofe by certain favages: but as we know nothing of the particular circumftances in which he was fituated, we can know as little Concerning his method of agriculture. The prodigious length of life which the antedilu¬ vians enjoyed, muft have been very favourable to the advancement of arts and fciences, efpecially agriculture, to which it behoved them to apply themfelves in a parti¬ cular manner, in order to procure their fubfiftence. It is probable, therefore, that, even in the antediluvian world, arts and fciences had made great progrefs, nay, might be farther advanced in fome refpeftsthan they are at prefent. Of this, however, we can form no judg¬ ment, as there are no hiftories of thofe times, and the fenpture gives us but very flight hints concerning thefe matters. No doubt, by the terrible cataftrophe of the flood, which overwhelmed the whole world, many fciences would be entirely loft, and agriculture would fuffer ; as it was impoflible that Noah or his children could put in pradlice, or perhaps know, all the different methods of cultivating the ground that were formerly ufed. The common methods, however, we cannot but fuppofe to have been known to him and his children, and by them tranfmitted to their pofterity : fo that as long as man¬ kind continued in one body without being difperfed in¬ to different nations, the arts, agriculture efpecially, would neceffarily advance; and that they did fo, is evident from the undertaking of the tower of Babel. It is from the difperfion of mankind confequent upon the confufion of tongues, that we muft date the origin of favage na¬ tions. In all focieties where different arts are cultiva¬ ted, there are fome perfons who have a kind of gene¬ ral knowledge of moft of thofe praftifed through the whole fociety, while others are in a manner ignorant of every one of them. If we fuppofe a few people of underftanding to feparate from the reft, and become the founders of a nation, it will probably be a civilized one, and the arts will begin to flourifh from its very origin ; but, if a nation is founded by others whofe in- tellects are in a manner callous to every human fcience (and of this kind there are many in the moft learned countries), the little knowledge or memory of arts that were among the original founders will be loft, and fuch a people will continue in a ftate of barharifm for many ages, unlefs the arts be brought to them from other nations. From this, or fimilar caufes, all nations of equal an¬ tiquity have not been equally favage, nor is there any folid reafoa for concluding that all nations were origi- 4 nally uncalled in agriculture ; though as we know not the original inftruments of hufbandry ufed by mankind when living in one fociety, we cannot fix the date of the improvements in this art. different nations have always been in a different ftate of civilization ; and agri¬ culture, as well as other arts, has always been in diffe¬ rent degrees of improvement among different nations at the fame time. From the earlieft accounts of the eaftern nations, we have reafon to think, that agriculture has at all times been underftood by them in confiderable perfection; feeing they were always fupplied not only with the ne- ceffaries, but the greateft luxuries of life. As foon as the defeendants of Abraham were fettled in Paleftine, they generally became huibandmen, from the chiefs of the tribe of Judah to the loweft branch of the family of Benjamin. High birth or rank did not at that time make any diftimftion, for agriculture was confidered as the moft honourable of all employ¬ ments ; witnefs the illuftrious examples of Gideon, Saul, and David. The Chaldeans, who inhabited the country where agriculture had its birth, carried that valuable art to a. degree of excellence unknown in former times. They cultivated their lands with great afliduity, and feem to have found out fome means of reftoring fertility to an exhaufted foil, by having plentiful harvefts in fucceffion ; on which account they were not obliged, as their prede - ceffors had been, to change their fituations,.in order to obtain a fufficiency for themfelves and their numerous - flocks and herds. The Egyptians, who, from the natural fertility of their country by the overflowing of the Nile, raifed every year vaft quantities of corn, were, fo fenfible of the bleflings refulting from agriculture, that they aferi- bed the invention of that art to Ofiris. They alfo re¬ garded Ifis, their fecond deity, as the difeoverer of the ufe of wheat and barley, which before grew wild in the fields, and were not applied by that people to the purpofes of food.. Their fuperftitious gratitude was carried fo far, as to worihip thofe animals which were employed in tillage ; and even to the produce of their lands, as leeks, onions, &c.. The divine honours paid to Bacchus in India were derived from the fame fource, he being coniidered in that country as the inventor of planting vineyards, and the other arts attendant upon agriculture.. It is alfo related of the ancient Perfians, on the moft refpeftable authority, that their kings laid afide their grandeur once every month to eat with hufbandmen.- This is a ftriking inftance of the high eftimation in which they held agriculture; for at that time arts were praftifed among that people in great perfeftion, parti¬ cularly thofe of weaving, needle-work, and embroidery. The precepts of the religion taught by their ancien j magi, or priefts, included the practice of agriculture* The faint among them was obliged to work out his falvation by purfuing all the labours of agriculture: And it was a maxim of the Zendavefta, that he who fows the ground with care and diligence, acquires a greater degree of religious merit, than he could have gained by the repetition of ten thoufand prayers. The Phenicians, fo well known in feripture by the name of Philijlines, were alfo remarkable for their at¬ tention to, and ikill in agriculture. But finding them¬ felves Hi ft or y. A G R I C U felves too much ciifturbed and confined by the incur- fions and conquefts of the Ifraelites, they fpread them- felves throughout the greateft part of the Mediterra¬ nean iflands, and carried with them their knowledge in the arts of cultivation. Mago, a famous general of the Carthaginians, is faid to have written no lefs than 28 books on the fubjedt; which Columella tells us were tranflated into Latin by the exprefs order of the Roman fenate. We are in¬ formed by the ancient writers, that Ceres was born in Sicily, where fhe firft invented the arts of tillage and of fowing corn. For this eflential fervice, fhe was, agreeably to the fuperftition of thofe ages, deified, and worfhipped as the goddefs- of plenty. The truth of this is, that in the time of Ceres, the ifland, through her endeavdurs and the induftry of the people, became very fruitful in corn; and agriculture was there efteem- ed fo honourable an employment, that even their kings did not difdain to praftife it with their own hands. But time,., which at firft gave birth to arts, often caufed them to be forgotten when they were removed from the place of their origin.. The defcendants of Noah, who fettled in Europe, doubtlefs carried their knowledge of agriculture with them into the regions which they fucceffively occupied. But *thofe who took poffeffion of Greece were fuch an uncivilized race, that they fed on roots, herbs, and acorns, after the man¬ ner of beafts. Pelafgus had taught them the culture of the oak, and the ufe of acorns as food ; for which fervice, we are told, divine honours were paid Inm by the people. The Athenians, who were the firft people that ac¬ quired any tinfture of politenefs, taught the ufe of corn to the reft of the Greeks. They alfo inftrufted them how to cultivate the ground, and to prepare it for the reception of the feed. This art, we are told, was taught them by Triptolemus. The Greeks foon per¬ ceived that bread was more wholefomej and its tafte more delicate, than that of acorns and the wild roots of the fields; accordingly they thanked the gods for fuch an unexpected and beneficial prefent, and honour¬ ed their benefactor. As the arts of cultivation increafed,. and the blef- fings they afforded became generally experienced, the people foon preferred them to whatever the ravages of conqueft, and the cruel depredations of favage life, could procure. And accordingly we find, that the A- thenian kings, thinking it more glorious to govern a fmall ftate wifely,. than to aggrandize themfelves, and enlarge the extent of their dominions by foreign con¬ quefts, withdrew their fubjefts from war, and moftly employed them in cultivating the earth. Thus, by continued application, they brought agriculture to a confiderable degree of perfection, and foon reduced it to an art.. Hefiod was the firft we know of among the Greeks who wrote on this interefting fubjeCt. According to the cuftom of the Oriental authors, he wrote in poetry, and embelHfhed his poem with luxuriant defcription and fubli-me imagery. He calls his poem Weeks and Days, becaufe-agriculture requires exaft obfervations on times and feafons. Xenophon has alfo, in his Oeconomics, remarked, that agriculture is the nurfing mother of the arts. For, fays he, “ where. agriculture fucceeds profperoufly, L T U R E. 245 there the arts thrive ; but where the earth neceffarily lies uncultivated, there the other arts are deftroyed.” Other eminent Greek writers upon agriculture were, Democritus of Abdera, Socraticus, Archytas, Tarentinus, Ariftotle, and Theophraftus, from whom the art received confiderable improvements. The ancient Romans efteemed agriculture fo honour¬ able an employment, that the moft illuftrious fenators of the empire, in the intervals of public concerns, ap¬ plied themfelvcs to this profeffion; and fuch was the fimplicity of thofe ages, that they affumed no appear¬ ance of magnificence and fplendor, or of majefty, but when they appeared in public. At their return from the toils of war, the taking of cities, and the fubduing of hoftile nations, their greateft generals were impatient till they were again employed in the arts of cultiva- Regulus, when in Africa,. requefted of the fenate to be recalled, left his farm might fuffer, for want of pro¬ per cultivation, in his abfence ; and the fenate wrote him foranfwer, that it ihould be taken care of at the public expence, while‘he continued to lead their ar¬ mies. Cato the ccnfor, after having governed extenfive provinces, and fubdued many warlike nations, did not think it below his dignity to write a Treatife on Agri¬ culture. This work (as we are told by Servius) he dedicated to his own fon, it being the firft Latin trea¬ tife written on this important fubjeft ; and it has been handed down to us in all its purity,. in the manner that Cato wrote it. Varro compofed a treatife on the fame fubjeft, and on a more regular plan. This work is embellilhed with all the Greek and Latin erudition of that learned author, who died 28 years before the commencement ' of the Chriftian; sera. Virgil, who- lived about the fame time, has,, in his Georgies, adorned this fubjeft with the language of the Mufes, and finely illuftrated the precepts and' rules of huibandry left by Hefiod, Mago, and Varro.. Columella, who flourifhed in the reign of the em¬ peror Claudius, wrote 12 books on huibandry, replete with important inftruftion. From this period to that of the reign of Conftantine Poganatus, huibandry continued in a declining ftate ; but that wife emperor caufed a large colleftion of the moft ufeful precepts relating to agriculture to be ex- .trafted from the belt writers, and publilhed them un¬ der the title of Geoponics. It has been afferted, that he made this colleftion with his own hand; and the truth . of the affertion is not improbable, as it is well known, that after he had conquered the Saracens and the Ar rabians, he not only praftifed and encouraged, but Hu- died the arts of peace, fixing his principal attention on . agriculture, as their belt foundation.' After the death of Conftantine, however, the in- creaiing attention of the people to commerce, and the ignorance and grofs fuperftition of the ages which fuc- ceeded, feems to have rendered agriculture an almoft ne- glefted feience. The irruptions of the northern na¬ tions foon abolifhed any improved fyftem. Thefe innu¬ merable and enterprifing barbarians, who over-ran all Europe, were originally Ihepherds or hunters, like the prefent Tartars and the favages of America. They con- tented themfdves with poffeffing thofe vaft deferts made 246 * Cafar de Bell Gall, lib. 5. c. 12, + Plin. Nar Hift.lrb.i; xap.6. A G R I C I by their own ravages, without labour or trouble, cul¬ tivating only a very fmall fpot near their habitations; and in this trifling hulbandry only the meanelt flavea were employed : fo that the art itfelf, which formerly was thought worthy of the ftudy of kings, was now looked upon as mean and ignoble ; a prejudice which is fcarcely effaced at prefent, or at leaft but very lately. — During this period, therefore, we find no veitiges •of any thing tolerably written on the fubjedl. No new attempts were made to revive it, or to improve it, till the year 1478, when Crefcenzio publiihed an excellent performance on the fubjeft at Florence. This rouzed the flumbering attention of his countrymen, feveral of whom foon followed his example. Among thefe, Tat- ti, Steffano Auguftino Gallo, Sanfovino, Lauro, and Tarello, deferve particular notice. At what time agriculture was introduced into Bri¬ tain, is uncertain. When Julius Casfar firft invaded this ifland, it was not wholly unknown. That conqueror was of opinion, that agriculture was firft introduced by fome of thofe colonies from Gaul which had fettled in the fouthern parts of Britain, about 100 years before the Roman invafion *. It is not to be expected that we can now be acquaint¬ ed with many of the practices of thefe ancient huf- bandmen. It appears, however, that they were not unacquainted, with the ufe of manures, particularly marie. This we have on the authority of Plinyf, who tells us, that it was peculiar to the people of Gaul and of Britain; that its effe&s continued 80 years; and that no man was ever known to marie his field twice, &c.—It is highly probable, too, that lime was at this time alfo ufed as a manure in Britain, it being certain¬ ly made ufe of in Gaul for this purpofe at the time of Julius Casfar’s invafion. The eftabliflrment of the Romans in Britain produ¬ ced great improvements in agriculture, infomuch that prodigious quantities of corn were annually exported from the ifland ; but when the Roman power began to decline, this, like all the other arts, declined alfo, and was almoft totally deftroyed by the departure of that people. The unhappy Britons were now expoied to frequent incurfions of the Scots and Pierfons to form themfelves into a fociety for fitting out one of thefe ploughs, providing it with oxen and every thing neceffary for ploughing ; and many minute and curious laws were made for the regulation of fuch fo- cieries. If any peribn laid dung on a field with the confent of the proprietor, he was by law allowed the ufe of that land for one year. If the dung was carried F L T U R E. Hi ilory. out in a cart in great abundance, he was to have the ufe of the land for three years. Whoever cut down a wood, and converted the ground into arable, with the confent of the owner, was to have the ufe of it for five years. If any one folded his cattle, for one year, up¬ on a piece of ground belonging to another, with the owner’s confent, he was allowed the ufe of that field for four years. Thus, though the Britons had in a great meafure loft the know ledge of agriculture, they appear to have been very affiduous in giving encouragement to fuch as would attempt a revival of it; but, among the Anglo- Saxons, things were not at prefent in fo good a ftate. Thefe reftlefs and haughty warriors, having contrac¬ ted a diftafte and contempt for agriculture, were at pains to enact laws to prevent its being followed by any other than women and flaves. When they firft arri¬ ved in Britain, they had no occafion for this art, being fupplied by the natives with all the neceffaries of life. After the commencement of hoftilities, the Saxons fubfifted chiefly by plunder: but having driven out or extirpated moft of the ancient Britons, and divided their lands among themfelves, they found themfelves in danger of ftarving, there being now no enemy to plun¬ der ; and therefore they were obliged to apply to agri¬ culture. The Saxon princes and great men, who, in the divi- fion of the lands, had received the greateft (hares, are faid to have fubdivided their eftates into two parts, which were called the in-lands and the out-lands. The in¬ lands were thofe which lay moft contiguous to the manfion-houfe of their, owner, which he kept in his own poffeffion, and cultivated by his (laves, uuder the direftion of a bailiff, for the purpofe of raifing provi- fions for the family. The out-lands were thofe at a greater diftance from the houfe, and were let to the cciorls, or farmers of thofe times, at very moderate rents. By the laws of Ina kmg of the weft Saxons, who reigned in the end of the feventh and beginning of the eighth century, a farm confiding of ten hides, or plough-lands, was to pay the following rent: “ Ten cades of honey; three hundred loaves of bread; twelve cades of (bong ale; thirty cades of fmall ale; two oxen ; ten wedders; ten geefe; twenty hens ; ten cheefes; one cafle of butter; five falmon; twenty pounds of forage ; and one hundred eels.” From this low rent, the imperfection of agriculture at that time is eafily difcoverable ; but it is (till more fo from the low prices at which land was then fold. In the ancient hiftory of the church of Ely, publiihed by Dr Gale, there are accounts of many purchafes of lands by jEdel- wold the founder of that church, and by other bene- fadtors, in the reign of Edgar the Peaceable, in the tenth century. By a comparifon of thefe accounts it appears, that the ordinary price of an acre of the beft land in that part of England, in thofe times, was no more than 16 Saxon pennies, or about four (hillings of pur money: a very trifling price, even in comparifon with that of other commodities at the fame time: for, by comparing other accounts, it appears, that four (beep were then equal in value to an acre of the beft land, and one horfe of the fame value with three acres. The frequent and deplorable famines which alflidted England about this time, are further inftances of the wretched ftate of agriculture. In 1043, a quarter of wheat fold iftory.

Gabriel Plattes may be faid to have been an origi¬ nal genius in hufbandry. He began his obfervations at an earlier period, in the reign of Queen Elizabeth, and continued them down to the Commonwealth. But notwithftanding the great merit of this writer, and the effential fervice he had rendered his country by his wri¬ tings, the public ungratefully fuffered him to ftarve and perilh in the ftreets of London; nor had he a fhirt on his back when he died. Samuel Hartlib, a celebrated writer on agriculture in the laft century, was highly efteemed and beloved by Milton, and other great men of his time. In the preface to his work intitled His Legacy, he laments that no public director of hufbandry was eftablifhed in England by authority ; and that we had not adopted the Flemifh method of letting farms upon improvement. This remark of Hartlib’s procured him a penfion of L. 100 a-year from Cromwell; and the writer after¬ wards, the better to fulfil the intention bf his bene- faftor, procured Dr Beatti’s excellent annotation on the Legacy, with other valuable papers from his nu¬ merous correfpondents.. The time in which Hartlih flourifhed feems to have been ari sera when the Englifh hufbandry rofe to great perfection, compared with that of former ages’; for the preceding wars had impoverifhed the country gen¬ tlemen, and of courfe made them induftrious. They found the cultivation of their own landslo be the moft profitable ftation they could fill. But this wife turn was not bf long continuance. At the Reftoration, they generally became inftcled with that intoxication and love of pleafure which fucceeded. Ali their in* duftry and knowledge were exchanged for negleft and diffipation; and hufbandry defcended almoft entirely into the hands of common farmers* Evelyn was the firft writer who infpired his Country¬ men with a defire of reviving the ftudy of agriculture; and he was followed by the famous Jethro Tull. The former, by his admirable treatifes on earth and on planting, and the latter, by {bowing the fuperior advan¬ tages of the drill-hufbandry, excited numbers to bring ■their theory to the teft of fair experiment. Many-valuable and capital improvements have, fince 'that period, been -made in Englifh hufbandry: and •thefe great men haye been fucceeded by a variety of writers, many of whom have done effential fervice, by enlightening the minds of their countrymen, and ex¬ citing them to emulation. About the middle of the laft century, Ireland be¬ gan to make a confiderable figure in the art of huf¬ bandry. It muft indeed be confefled, that the Irifh had very ftrong prejudices in favour of a wretched me¬ thod of agriculture, till Blyth opened their eyes by his excellent writings. Since that time, a fpirit of im¬ provement has more or lefs been promoted, and in many inftances carried on with great zeal, by the N° 7. L T U R E. H nobility, clergy, and gentry of that kingdom. In proof of this, it will be fufficient to obferve, that the Tranfaftions of the Dublin Society for encourage- ing Hufbandry are now cited by all foreigners in their memoirs relating to that fubjech And the obferva¬ tions of that difcerning and judicious writer, Arthur Young, Efq; in his late Tour through that kingdom, fhow, that in many refpefts improvements there have of late years made a progrefs nearly as rapid as in England. After the peace of Aix-la-Chapelle, moft of the na¬ tions of Europe, by a fort of tacit confent, applied themfelves to the ftudy of agriculture, and continued to do fo, more or lefs, amidft the univerfal confufion that fucceeded. The French found, by repeated experience, that they could never maintain a long war, or procure a to¬ lerable peace, unlefs they could raife corn enough to fupport themfelves in fuch a manner as not to be ob¬ liged to harfh terms on the one hand, or to perifh by famine on the other. This occafioned the King to give public encouragement to agriculture, and even to be prefent at the making of feveral experiments. The great, and the rich of various ranks and ftations, fol¬ lowed his example-; and even the ladies were candi¬ dates for a fhare of fame in this public-fpirited and commendable undertaking. During the hurry and diftreffeS of France in the war of 1756, confiderable attention was paid to agricul¬ ture. Frize-queftions were annually propofed in their rural academies, particularly thofe of Lyons and Bdur- deaux ; and many judicious obfervations were made by the Society for improving agriculture in Brittany. ■Since the conclufion of that war in 1760, matters have been carried on there with great vigour. The univerfity of Amiens made various propofals for the advancement of hulbandry ; and the Marquis de Tour- billy (a writer who proceeded chiefly on experience) had the principal direction of a Georgical fociety efta- bliihed at Tours. The fociety at Rouen alfo deferves notice; nor have the King and his minifters thought it unworthy their attention. There are at prefent about fifteen focieties exifting in France, eftablifhed by royal approbation, for the promoting of agriculture; and thefe have twen¬ ty co-operating focieties belonging to them. About this time vigorous exertions began to be made in Ruffia to introduce the moft approved fyftem of hulbandry which had taken place in other parts of Europe. The prefent Emprefs has fent feveral gentle¬ men into Britain and other countries to ftudy agricul¬ ture, and is giving it all poffible encouragement in her own dominions. The art of agriculture has alfo been for near 30 years publicly taught in the Swedifh, Danifh, and German univerfities, where the profeflbrs may render effedtual fervice to their refpeftive countries, if they underftand the practical as well as the fpeculative part, and can converfe with as much advantage with the far¬ mer as with Virgil and Columella. Even Italy has not been totally inaftive. The Nea¬ politans of this age have condefcended to recur to the firft rudiments of revived hiiibandry, and begun to ftu¬ dy anew the Agricultural Syftem of Crefcenzio, firft publilhed in 1478. The people of Bergamo have our- fued !Hiilory. A G R I C U fued the fame plan, and given a new edition of the Ri- ■ ' cordo d’Agriculturae de Tarello, firftpublirtied in 1577. The dutchy of Tufcany have imbibed the fam& fpirit for improvement. A private gentleman, above 40 years lince, left his whole fortune to endow an academy of agriculture. The firft ecclefiaftic in the dutchy is pre- fident of this fociety, and many of the chief nobility are members. His SardinianMajefty has alfo fent perfons to learn the different modes of praftice in foreign countries ; and made fome fpirited attempts to ellablifh a better me- f thod of agriculture among his fubje&s. In Poland, alfo, M. De Bielufki, grand marfhal of the crown, has made many fuccefsful attempts to in¬ troduce the new hufbandry among his countrymen ; and prdcured the befl; inttruments for that purpofe from France, England, and other parts of Europe. The Hollanders are the only people now in Europe jh who feem to look upon agriculture with indifference. Except the Angle collateral inftance of draining their fens and moraffes, they have fcarcely paid any atten¬ tion to it; and even this feems to have proceeded more from the motive of felf-prefervation than any love of, or difpofition to, hufbandry. In the year 1759, a few ingenious and public- fpirited men at Berne in Switzerland eflablifhed a fo¬ ciety for the advancement of agriculture and rural ceconomics. In that fociety were many men of great weight in the republic, and moft of them perfons of a true call: for making improvements in hufbandry, being enabled to join the practice with the theory. Nor muff we here omit to mention, that the juftly cele- j brated Linnaeus and his difciples have performed great things in the north of Europe, particularly in difeover- ing new kinds of profitable and well-tafted food for cat¬ tle. About the fame time, Sweden bellowed fuccefsful labours on a foil which had before been looked upon as cold, barren, and incapable of melioration. Of this the Stockholm Memoirs will be a lafling monument. Denmark, and many of the courts in Germany, fol¬ lowed the fame example. Woollen manufactures were encouraged, and his Danifh Majefty fent three perfons into Arabia Felix to make remarks, and bring over fuch plants and trees as would be ufeful in hufbandry, building, and rural affairs. The duchy of Wirtemburgh, alfo, a country by no means unfertile, but even friendly to corn and paf- turage, has contributed its afliftance towards the im¬ provement of agriculture, having more than 30 years fince publifhed 14 ceconomical relations.at Stutgard. Neither muft we forget the very affiduous attention L T U R E. of the learned in Leipfic and Hanover to this im¬ portant object. During the rage and devaftation of a long war, they cultivated the arts of peace; witnefs the Journal dr Agriculture printed at Leipfic, and the Recueils d' Hanover printed in that city. Even Spain, conftitutionally and habitually inaftive on fuch occafions, in fpite of all their natural indo¬ lence, and the prejudices of bigotry, invited Linnaeus, with the offer of a large penfion, to fuperintend a col¬ lege founded for the purpofe of making new enqui¬ ries into the hiftory of Nature and the art of agriculture. Among the Japanefe, agriculture is in great repute; and among the Chinefe it is diftinguifhed and encou¬ raged by the court beyond all other fciences. The Emperor of China yearly, at the beginning of fpring, goes to plough in perfon, attended by all the princes and grandees of the empire. The ceremony is performed with great folemnity ; and is accompanied with a fa- crifice, which the emperor, as high-prieft, offers to Chang-Ti, to enfure a plentiful crop in favour of his people. But, without any improper partiality to pur own country, we are fully juftified in afferting, that Bri¬ tain alone exceeds all modern nations in hulbandry; and from the fpirit which for the laft twenty years has animated many of our nobility and gentry, to become the liberal patrons of improvement, there is reafon to hope that this moft ufeful of arts will, in a few years, be carried to a greater pitch of per¬ fection than it has ever yet attained in any age or country.—The Royal Society, the Bath Society, and the Society of Arts, &c. in particular, have been fig- nally ufeful in this refpeft ; and the other affociations, which are now eftablilhed in many parts of the kingdom, co-operate with them in forwarding their laudable de- fign. _ It is not, however, to the exertion of public focie- ties, excellent and honourable as they are, that all our modern improvements in agriculture owe their origin. To the natural genius of the people have been added the theory and praClice of all nations in ancient and modern times. This accumulated mafs of knowledge has been arranged, divided, and fubdivided ; and after paffrng the teft of practical experiments, the effential and moft valuable parts of it have been preferved, im¬ proved, and amply diffufed in the works of Lord Karnes, Mr Young, Stillingfleet, Dr Hunter, Ander- fon, Dickfon, Ellis, Randal, Lifle, Marlhal, Mortimer, Duhamel, Bradley, Kent, Mills, and a few other wri¬ ters upon this great art of rendering mankind happy; wealthy, and powerful. PartI. THEORY of AGRICULTURE. IN an art fo extenfively ufeful to mankind, and which has been fo univerfally pra&ifed fince the creation of the world, it is natural to expedl the moft exaft and perfect theory. But in this we are totally difap- Ignorance pointed. i of the food One reafon of this want of a diftinCt theory of agri- jf of vege* culture is, the ignorance of what is properly the food reafon of6 vegetables; for as the art of agriculture coniifts imperfec- principally in fupplying them with a proper quaptity of j tion in the food, in the moft favourable circumftances, it is evi- theory of a- dent, we might proceed upon a much furer foun- : griculture. y0L< L part p dation if we could afcertain what their proper nou- rifliment is, than we can do without this knowledge. —The reafon of the great differences regarding the pra&ice, probably, is the difficulty of making experi¬ ments in agriculture. It is not in this art as in Me¬ chanics, Chemiftry, &c. where an experiment can be made in an hour, or a day or two at fartheft : an ex¬ periment in agriculture cannot be properly made in lefs than feveral years.: Some favourable unobferved cir¬ cumftances, quite foreign to the experiment itfelf, may concur to produce plentiful crops for a year or two : I i and 25Q AGRIC ULTURE.

Were he, however, capable of feeing and handling-the food of vegetables, as well as he can . do that of a horfe or an ox, and procuring it in any imaginable quantity, it is plain, that he would be able to caufe vegetables grow in their utmoft luxuriancy,, or, if we may be allowed the expreffion, fatten them, with as great certainty as he can fatten a horfe or an ox, when he hath plenty-of proper food to give them.—To afcertain what this food is, therefore, muft. be a ftep towards the perfection of agriculture.;, and to this we fliall .contribute our endea¬ vour. . ^ Sect. I. Of the proper Food of Plants- Various fuppofitions not fpen(j t;me ;n refuting the theories the^oo^of t^°fe who imagined the vegetable food to confxft plants. of oily and faline fubftances. A more probable fuppo- fition has been, That Water and Air are the proper vegetable food, to which alone they owe their increafe in bulk and weight.—That plants cannot be fupported without both thefe, is very certain : but we know, that air is a compound fluid; and water is never without feme impurities, fo may alfo be confidered as a com¬ pound.— Is it then the aqueous, the earthy, the acid, or the phlogiftic part of the air, which nourilhes plants? In- like manner, is it the pure elementary part of water which nouriflies them ? or does it contribute to their growth only by the heterogeneous fubftanees which it 3 contains ? Vegetables From Dr Prieftley’s experiments on different kinds thrive in Df ai'r> Jt appears that the pureft kind of that fluid is putrid air. not ^ for the purpofes of vegetation. On the contrary, vegetables flouriflied in a furprifing degree when confined in a fmall quantity of air made perfeClly noxious by the putrid effluvia of animal bodies.— Hence it appears probable, that fuch effluvia, or, in other words, the effence of corrupted matter, conftitute at leaft one fpecies of vegetable food ; and when vege¬ tables are put into fuch circumftances that the fteams of putrefying bodies can have accefs to them, we are 4 fare they will thrive the better. Water ca- The DoCtor alfo found, that by agitating putrid air hibin 'n water> Part of which was expofed to the atmofphere, tridcfflu-' t^ie water acquired a very putrid noxious fmell; which via. ftiows, that water, as well as air, is capable of abforbing thofe effluvia which are found proper food for vegetables. We cannot help concluding, therefore, that in the con¬ tinual afcent of water in vapour, and its defcent again in rain, which is a much, more effeftual agitation than could be made by Dr Prieftley, the water muff be very intimately combined, with the phlogiftic or putrid efflu¬ via which are contained in the air. To this union we are led ftrongly' to fufpett that rain-water owes its fer¬ tilizing qualities ; for the pureft fpring waters, though j moft wholefome for animals, are not found to be fitteft Putrid ef- for promoting the growth of vegetables.—As, there- fiuvia the fore, vegetables evidently receive nouriflunent both by proper food their kaves and roots, and increafe remarkably in bulk * P *n 5* Jiy abforbing the putrid effluvia from the air ; and as they like wife increafe in bulk by admitting water to Theory. their roots, and more fo when the water contains much 1 r-—* of that kind of effluvium than when it contains lefs: fo we would conclude, that the nouriihment recei¬ ved by the roots of plants is of the fame kind with that received by their leaves; and that this food may be given them in greater plenty than they naturally re¬ ceive it, by impregnating the air which furrounds them, or the water which moiftens them, with a greater quan¬ tity of putrid matter than what they contain in a natu¬ ral ftate. Sect. II. The foregoing Theory confirmed from con- fidcrations on the nature of vegetable Mouldy and the different kinds of Manure found proper for fertilizing the Soil. ^ Though plants will grow on any kind of earth, and kinds of | ftourilh vigoroufly, if plentiffflly fupplied with water ; yet fome kinds of foil are found much more proper for per for nou.. | fupplying them with nourifhment than others.—Werifliingve- | cannot, indeed, allow the inferences to be quite fair getables. which fqme would draw from experiments on plants fet in mere fand, &c.; viz. that the earth is of no other ufe to vegetation than to afford a proper fupport to the plant, that it be not eafily moved out of its place ; be- caufe the experiments made on fingle vegetables are al¬ ways performed in or very near houfes, where the air is by no means fo pure as in the open fields, and con- fequently where they have an opportunity of receiving as much nourifhment from the air as may compenfate the want of what they would have derived from the earth if planted in a rich foil. Lord Karnes, in the Gentleman Farmer, mentions an experiment wherein a pea was planted on fome cotton fpread on water, in a phial. It fprung, and puftied roots through the cotton into the water. The plant grew vigoroufly, and, at the time of his writing the experiment, carried large pods full of ripe feed.—From this experiment, or others of a fimilar kind, however, a farmer would not be thought to aft very judicioufly, who fhould conclude that nothing more was requifite to produce a plentiful crop, than to keep his fields conftantly foaking with water, and apply his labour only for that purpofe, with¬ out regarding either tillage, manure, or the difference of foils. Experience has abundantly fliown, that by certain operations performed on the earth itfelf, it is rendered much more capable of fupplying vegetables >1 with plenty of nourifhment than if fuch operations were omitted ; and that fome kinds of foils cannot without certain additions be rendered fo fit for this purpofe as others ; and this is what conftitutes the difference be¬ tween a rich and a poor foil. ^ That fpecies of earth which is capable of fupply- of the tnn t ing the vegetable kingdom with nourifhment in the vegetable j i greateft plenty, is found beft in well cultivated gar- earth* dens. It is not, however, even in thefe, found in per- feft purity ; being conftantly mixed with greater or lefs proportions of fand, fmall ftones, &c. It can be had. by itfelf, and entirely feparated from all other fubftances, only by fuffering vegetable or animal bodies to putrefy. By undergoing this operation, they are at laft refolved into a kind of earth, which appears perfeftly the fame, from whatever fubftance it is produced. Of this earth Dr Lewis gives us the following charafters. It is in- diffoluble li Part T. AGRICULTURE. 251 ''I'l Theory, diflbluble in acids, fomewhat tenacious when moiftened ' with water, friable when dry, and acquires no addition¬ al hardnefs in the fire.—The chemiftry of nature, and that of art, however, are fo very difiimilar, that an ac¬ count of the chemical properties of this earth can be but of very little fervice to the practice of agriculture ; how¬ ever, to thofe above mentioned we may add, that when it is difiilled with a violent fire, a volatile alkaline fpi- rit, and foetid oil, fimilar to thofe of hartfhorn or other animal fubftances, are obtained. As the volatile alkali is known to be produced in great plenty by diftilling putrid fubftances either ani¬ mal or vegetable, the obtaining aa alkaline fpirit from this kind of earth is a ftrong argument of its being much impregnated with the putrid effluvium, wrhich we have already mentioned as the proper vegetable food contained in the air and water. Indeed, confidering that this kind of earth is produced by putrefa&ion, it is next to an impofiibiiity that it ftiould not be impreg¬ nated with putrid fleams, as much as earth can be; and if the earth which is moft impregnated with thefe fleams is found to afford the greateft quantity of nouriftiment to vegetables, we have from thence an additional proof that they live on. the putrid matter emitted from dead ^ . animals and vegetables like themfelves. ’ Earth is ca- That we may be the more afeertained of this, it pable of ab- mull be confidered, that the earth, which undoubtedly l0-a *>U" *s t^e great Source of nourifhment to vegetables, is ca- I; in prochgi- Pable of abforbing putrid effluvia more powerfully, or I cus quanti- at leaft in much greater quantity, before it is faturated, ' ties. than either the air or water. The pradlice of bury¬ ing dead bodies is an undeniable proof of this. They are laid but a fmall depth under ground ; yet the abo¬ minable1 flench emitted by the carcafe is retained in the earth, fo that it never penetrates in fuch a man¬ ner as to be offenfive. That earth may be faturated with this putrid matter, as well as air or water, is very I certain; and, in cafe of fuch a faturation, no doubt either of thefe will take up the fuperfluous quantity, and become noxious : but unlefs the earth is fully fa¬ turated, both of them will depofite part of what they themfelves contain in the earth, and by that means be- I0 come more falutary than they were before. Agreeable That earth is capable of attracting putrid effluvia from odour emit- the air, perhaps, may not be fo readily granted; and in- 1 te,l bymoift ({eeci we know Gf no experiment whereby it can be j eanh' fhown that putrid air is made falutary by having any kind of earth agitated in it: but if we confider the ex¬ ceeding great falubrity of the air in the country, and the healthinefs of thofe who follow the plough or are employed in digging the ground, we mull at leaft al¬ low, that when the ground is turned up, it communi¬ cates no kind of noxious quality to the air; which it would certainly do, if it emitted A putrid effluvium. So far from this, the fmell of moift earth is always a- greeable and wholefome; and here we have the fatisfac- tion to find our theory fomewhat confirmed by the ce¬ lebrated Baron van Swieten, late phyfician to the em- * prefs of Hungary. “ Phyficians,” fays he, “ ufually advife their patients to ruftication, not only that they may enjoy a pure and freely circulating air; but that, as their ftrength in- creafes, they may, difengaged from all care, exercife their body by the /lighter labours of agriculture, and other country amufements. 8 This earth , impregna¬ ted with Iputrid ef¬ fluvia. “ There may perhaps be another caufe why ruftica- Theory, tion will be of benefit in confumptions. It is well ■ ' known, that, after fome days drought, on the falling of rain that moiftens the earth, there arifes a grateful fmell, which we all are fenfible of; and this is common¬ ly attributed to the vegetables, which before faplefs, but now refrelhed by rain, perfpire more copioully. But Reaumur obferved, that a like fragrancy is alfo per¬ ceptible after rain when the corn has been cut down in the fields, where there only remains dry ftubble ; and examining the matter more particularly, he found that dry earth is without fmell, but as foon as it is moiften¬ ed to the degree of having the confiftence offoftilh pap, it then diffufes a ftrong fmell; but if more water is added, the fmell is diminifhed, nay even quite diffipated. Neither does it feem an eafy matter to exhauft that power of producing fmells which the earth is poffeffed of. E- very day, during a fortnight, he made cakes of moiftened earth; and having dried and wetted them over again, he could not perceive that the earth was lefs fragrant after all thefe repeated experiments, if it was again wetted. He further obferved, that this fragrancy does not diffufe itfdf to anything at a greatdiftance,without being much diminilhed, and foon entirely gone.—It has been ob¬ ferved, that this exfpiration of the earth ceafes if thun¬ der and ftorms foon follow: while they continue, it be¬ gins to return ; and when over, the fame fragrancy of the earth for fome hours affe&s the fmell of a man as he walks along over a confiderable trad of ground. There is no one, I believe, but has fometimes made this obfervation ; and hence the earth, when moiftened to a certain degree, feems to exhale fragrant odours, and indeed various in various places, as we are fenfible of from their diverfity. They are for the moft part of a falubrious quality ; as fome perfons quite faint and languid in the fummer-heats perceive themfelves won¬ derfully refrelhed, whilft, after rain, they fnuff up the fragrant odour. In fome places thofe effluvia are per¬ haps bad, and may be the caufes of difeafes.” This property of emitting a fragrant fmell is like- wife taken notice of by Dr Home in his Principles of Agriculture and Vegetation. Some phyficians have preferibed a bath of earth for the cure of confump- tive patients; and Dr Solano de Luque was of opinion, that the earth had the property of abforbing conta¬ gious miafmata into it: but whether it can abforb thefe miafmata from living bodies or not, it certainly can ab¬ forb them from dead ones ; for a piece of putrid meat will be much fweetened by lying for a Ihort-time in the ground. „ From all this we cannot indeed infer, that putrid Power of air is fweetened by mere earth ; but we difeover what tranfmuta- is perhaps more important, namely, that though earth tlon in the is the common receptacle of all putrid matters both ^rt a ert* animal and vegetable, there is a change made on them when in it, which cannot be made either by air or win¬ ter. Thus, if the carc^fe of a fmall animal is left to putrefy in the air, it becomes exceedingly offenfive, and continues fo from firft to laft. The fame thing happens if it is left to putrefy in water. But, in earth, the cafe is quite different. After the carcafe is con- fumed, the earth Vhich has imbibed all the putrid fleams, inftead of exhaling an offenfive odour, diffufes an agreeable one ; and thus we may fee that it is en¬ dued with a power no lefs remarkable than that of at- I i 2 traftion 252 A G R I C U [ Theory, traftion or repulfion, and which we may diftinguifh by ' v ' the name of tranfmutation. With regard to water, the cafe is more evident; for the moft putrid water will be fweetened by percolation through earth, or even running in a channel for fome time on its furface ; but if it contains any impurities of the faline kind, they will not be feparated, or at lead: in very fmall quan- tit5r* Attraction The exiftence of fuch a power as that of tranfmuta- infufficient tion we will be obliged to own, whatever we imagine to folve the the vegetable food to confift of; for it is impoflible to of veeeta-3 ^ve the Phenomena of vegetation by attractions and Sion. repulfions. If we fuppofe the vegetable food to be fait, let us attract and repel fait as we will, it remains fait from firft to laft. Let us fuppofe it water, the cafe is the fame ; and, by mere attraction, nothing but mafles of fait, or pools of water, could be produced. The cafe is the fame on our own hypothefis; for, fup- pofing plants compofed of the putrid effluvia of others, and of dead animals, if nature was endued with no other power than attraction or repulfion, the vegetable would neceffarily be a corrupted mafs like that of which it was compofed.—This power, as we have already feen, refides only in the earth, and in the vegetables them- felves; air and water can- indeed act as powerful fol- 13 vents, but cannot transform or compound. Confirma- We mud next confider the nature of thofe different abovcftheo oPerat'0ns> which, from time immemorial, have been ry from the Perf°rmed on the earth, in order to caufe it produce different o- the greated crops of vegetables. If all of thefe (hall perations ofbe found confpiring to one general purpofe, then the agriculture, fhorted and mod eafy method of attaining that pur¬ pofe is undoubtedly the mod proper to be pra&ifed in agriculture, whether it hath been as yet put in execu- tion or not. Thefe. are, Fallowing. Frequent ploughing, or fallowing. The imme¬ diate confequences of this is to expofe different quan¬ tities of the foil to the aedion of the air and fun, which will not fail to exei;t their folvent powers upon it. In confeqiience of this aedion, the earth is partly reduced to powder; many of the roots of vegetables, with which it always abounds, are diffolyed and putrefied ; and the earth .produced from them mixes with the red, as well as the effluyia they emit during their diffolution. The earth foon begins again to exert its prolific powers, and a crop of vegetables is produced. By a repetition of the ploughing, thefe are turned with their roots up¬ wards, are expofed to the folvent powers of the air and light yin confequence of which they die, are putrefied, and more of the native foil is reduced to powder, and mixed with them. By a frequent repetition of this procefs, the foil becomes vadly more tender, and ap¬ proaches to the nature of garden-mould, and its ferti- lity is confiderably increafed. The capaci- Lord Kames is of opinion, that the reafon of the ty of a foil fertility of any foil being increafed by fallowing, is, to retain that its capacity of retaining water is increafed. But irejeafedby cannot be admitted; for fo far from being more fallowing, difpofed to retain water by its pulverifation, the foil is evidently more difpofed to part with it, either by eva¬ poration, orby fuffering the moifture to percolate thro’ it. In this refpeft it is far inferior to clay; for though dry garden-mould abforbs water much more quickly than clay, it alfo dries much fooner, and thus all the advantage is loft. L T U R E. Parti. To thofe who reckon the food of vegetables to con- | Theory. fift of oils or falts, the operation of fallowing ground ^ muft appear an ufelefs one, as it can tend neither to 0;]s ancj produce oils nor falts, but to deftroy them. As its falts not the utility, however, cannot be denied, the favourers oftr^ vfeg this theory imagine, that the ground, by repeated ope-ta e 00 rations' of this kind, is fitted for attrafting the nitrous falts from the air: but it is found, that thefe falts can¬ not be attra&ed by earth, or any other fubftance, even when Ckpofed for a great length of time to the air with a view to produce falt-petre ; which gives a ftrong fufpicion againft their exiftence; and even if nitre is mixed with the foil, it is found to be detrimental, and will kill or poifon plants inftead of nouriftiing them. 17 2. Overflowing the ground with water.—This is Overflow- found prodigioufly to increafe the fertility of any foil. It is well known how much Egypt owes to the annual overflowing of the Nile ; and even in this country the overflowing of any ground is found to be attended with great advantage. This is practifed by Mr Bakewell of Leicefterfhire, famous for his improvements in the breed of cattle ; and he finds it fully to anfwer an an¬ nual manuring of any other fort. It is alfo recom¬ mended by Mr Anderfon of Monkfliill, in his Effays on Agriculture. ,g The fertilizing quality of water will eafily he ac- Reaf ns of counted for on the fame principles. When grown ve- increafe getables are covered with water, their growth, how-£yt^re“e5r_ ever vigorous before, is immediately ftopt, unlefs they flowing, be of the aquatic kind: they die, are diffolved, and putrefied; in which cafe, their finer parts are undoubt¬ edly abforbed by the earth : and thus, the floating, as it is called, of fields with water, anfvvers the purpofe of fallowing, with very little trouble. This is not all: for ftagnating water always depofites a fediment, which mixing'with the diffolved parts. of the vegetables all over the field, forms an excellent manure ; and when the water is allowed to run off, the heat of the fun foon brings the higheft degree of putrefa&ion on the dead vegetables; the effluvia of which, mixing with the mud depofited from the water, makes it exceedingly rich. Upon the fuppofition of oily and faline food for ve- oils ^ fa]ts getables, this operation muft;. certainly be prejudicial; cannot be for nothing can fo effeftually deprive any fubftance of the vegeta* fait as fteeping it in water. Neither will water either ^0£** depofite oilfrom itfelf, or fuffer it to mix with theground if accidentally brought to it; nay, though a field were previoufly impregnated with oil. upon overflowing it with water great part of the oil would be feparated, and rife to the top : fo that, in either cafe, this opera¬ tion could not fail to impoverilh land rather than enrich it; and as vegetables are found to be fupplied with food in plenty by an operation which muft undoubtedly tend to take away both oils and falts from them, we cannot help thinking this, a demonftration, that their. food is compofed neither of oil nor fait. ao 3. Manuring, or mixing the foil with different fub- Ofmanures, ftances.—We fa all here confine ourfelves to thofe which and their o- are of undoubted efficacy, and have their credit efta- pemion*. blilhed by long experience. Thefe are, 1. lime, chalk, marie, ihells, or other earths, called by the chemifts calcareous earths; 2. foot; 3. afhes : 4. dung of dif¬ ferent kinds.—(1.) The lime, chalk, marie, and ftiells, are all found to be of the fame nature. The marie differs from the reft, only in having a mixture of clay along "art I. AGRICULTURE. 253 Theory, along with its calcareous part. Thefe contain neither falt nor oil of any kind ; they readily imbibe water, and as readily part with it. Quicklime, indeed, retains water very obftinately: but fuch lime as is laid upon the ground foon returns to the fame ftate in which it originally was; and powdered limeftone is found to anfwer as well for the purpofes of manure as that which has been burnt; fo that here we may conlider them all as-fubftances of the fame clafs.—If any of thefe fubftances are mixed with dead animal or vegetable bodies, they remarkably quicken their diflblution and corruption, as appears from Sir John Pringle’s expe¬ riments on putrefaftion. When mixed with the foil, therefore, they mult undoubtedly exert their powers on fuch fubftances as they find there, in the fame manner as they do on others; that is, they muft haften their diflblution and putrefaction, and give the pure vege¬ table mould an opportunity of abforbing their putrid {teams, and confequently of being fertilized by it in the fame manner as by putrid fubftances of any kind. (2.) Thofe who contend for oily and faline principles in the vegetable food, avail themfelves of the ufefulnefs of foot as a manure ; which is not only oily of itfelf, but affords a great quantity of volatile fait, along with fome neutral fal-ammoniac. It muft be remembered, however, that not an atom either of volatile fait or fal- ammoniac can be extrafted from foot without a confi- derable heat, which no foil can give, nor could any vegetable bear. Neither doth its oil appear without a great degree of heat: and though it feels fomewhat unCtuous to the touch, this is but a mere deception ; for no true oil, capable of floating on water, can be ob¬ tained from foot without diftillation. It is impoffible, therefore, that foot can aft upon the foil either as an oily or a faline fubftance; how far it is capable of dif- folution by putrefaftion, or being otherwife converted into an earth, hath not yet been determined by expe¬ riments*, but as it yields, on diftillation, the fame principles which are obtained from animal or putrefied vegetable fubftances, it is probable that foot enriches the ground in the fame manner that they do. (3.) The * ufe of aflies in manure is likewife. urged as an argument for the food of vegetables being of a faline nature ; as it is known, that the common alkaline falts are procured by lixiviating the alhes of wood and other vegetables. Experience, however, fhows us, that aflies are "no lefs fit for manure after the fait is extrafted from them than before. Indeed, if there be any difference, it is in fa¬ vour of the waftied aflies. The alkali itfelf, though in Sir John Pringle’s experiments it was found to be an/i- feptic, or a refifter of putrefaftion, is neverthelefs a powerful diffolvent; and as it muft foon lofe its alkaline properties when mixed with the earth, in confequence of the univerfal exiftence of the vitriolic acid, thofe fubftances which it has diffolved will be more difpofed to putrefaftion than before, and confequently tend to fertilize the ground in the manner we have already de- fcribed. The waflied aflies are feptics, or promoters • of putrefaftion, and confequently aft in the fame man¬ ner as chalk or limeftone. (4.) All kinds of dung are fo much difpofed to putrefaftion, that it is difficult to imagine any other way in which they can be ferviceable to vegetation than by their putrid effluvia.—People in¬ deed may dream of imaginary falts in dung; but if they knew or, confidered the difficulty of procuring fait of any kind from dung, they would probably al- Theory. ^ ter their fentiments. The volatile falts procured from ^* this as well as other animal matters, are mere creatures of the fire: putrid urine produces them indeed w'ithout heat, but fcarce any other animal fubftance. Never¬ thelefs, other putrid fubftances will fertilize the ground as well as urine, and therefore muft aft in fome other way than by their falts. Though Dr Prieftley’s experi¬ ments had never been made, we could have formed no other rational fuppofition concerning the manner in which putrid fubftances fertilize the earth, than what we have already done ; but as he has fhown that vege¬ tables are prodigioufly increafed in bulk by the mere contaft of thefe putrid {teams, where no faline fub¬ ftances could have accefs to them, we cannot help think¬ ing this a decifive experiment concerning the manner in which the ground is fertilized by manuring with dung or other putrid fubftances. 41 We ftiall conclude this part of the fubjeft with an ac- Efferts of count of fome experiments concerning the effefts of fa- ^ine fe¬ line fubftances on the growth of vegetables. The fol- growing” lowing are related by Lord Karnes, in his Gentleman vegetables. Farmer.—“ A number of Jerufalem artichokes were fet in pots filled with pure fand. One plant was kept as a* ftandard, being nourifhed with W’ater only. Other plants of the fame kind were nouriftied with water in which fait of tartar, a fixed alkali, was diffolved. Thefe grew more vigoroufly than the ftandard plant; but, by reiterated waterings, there came to be fuch an accumulation of the fixed alkali among the fand, as to make the plants decay, and at laft to die. Some plants were nouriftied with water in which fal-ammoniac, a volatile alkali, was diffolved. Thefe grew alfo well for fome time; but, like the former, were deftroyed by frequent reiterations of it. Weak lime-water promo¬ ted the growth of its plants more than common water. But water completely faturated with quicklime, pro¬ ved more noxious than that which contained a fixed al¬ kali, though lefs than that which contained a folution of volatile alkali.—Urine promoted, for a long time, the growth of its plants; and the mofi putrid appeared to have the flrongeji effett; but at laft it totally deftroyed them. Water impregnated with putrid animal and ve¬ getable fubjlances, did more effectually promote the growth ' of its plants than any other folution ; and in every ffage of the procefs appeared to be falutary.,> With regard to other faline fubftances, there are not Common many experiments which can be depended upon con- - Se¬ cerning their qualities as a manure. Mr Anderfon re-tua ^ a lates an experiment made with common fait; the fuccefsmanUre’ of which, we apprehend, may juftly enough be taken as a fpecimen of what is to be expefted from manures of a fimilar kind.—He marked out a circle of fix feet diameter in the middle of a grafs-field, which he di- ftinguiflied by driving a ftake in its centre. All over this circle he ftrewed common fait, which, about the ftake, lay near an inch thick on the ground. In this ftate he left it to the operations of nature. The grafs fprung up as ufual, neither better nor worfe about the ftake than in the reft of the field, and the place where the circle was could be diftinguifhed only by the ftake, wdiich was left there for fome years. Upon thefe experiments we need make very few ob- fervations. They are fo much in favour of our theory, that they feetn made on purpofe to confirm it. The- fixed i 254 A G R I C U Theory, fixed alkali employed in Lord Karnes’s experiments would firft exert its folvent powers on fuch heteroge¬ neous fubftances as it met with among the fand; for no fand can be fuppofed to be perfe&ly free of thefe. As long as it exerted its ftrength on thefe only, the plant would thrive, for the reafons we have already men¬ tioned ; but having exhaufted the fmall quantity of fub* fiances contained in the fand, it would next attack the plant itfelf,which confequentlywoulddecayanddie. The fame effedls would neceffarily follow in a greater degree from ftrong lime-water which contains lime in its cau- flic date ; for this is a more powerful folvent than fix¬ ed alkali itfelf, and would not fail to deftroy every thing it touched; nor is it at all improbable that the plant would feem to grow vigoroufly by the diflblution of part of its own roots, more nourilhment being by this means given to thofe which remained found.—Volatile alkali is likewife a powerful folvent: but, by reafon of its volatility, would exert its cauflic power on the plant fooner than either lime or fixed alkali; and according¬ ly it feems to have been the moft deftruclive of any thing that was tried. It feems owing to this, that pu¬ trid urine at laft deftroyed the plants whofe growth it fo long promoted; while water impregnated with other putrid matters, which yield no volatile alkali without heat, proved always falutary. End to be From all this, we may draw the following general kept In view conclufion, viz. That the principal end which a farmer by a farmer, to keep in view, is to impregnate his ground as much as poffible, with fubflances which either actually contain putrid matter, or which are in their own na¬ ture feptic, or promoters of putrefaction. To impreg¬ nate the air with putrid effluvia is impoffible : and tho’ it could be done, would be highly dangerous; for how¬ ever falutary fuch effluvia may be to vegetables, nothing can be more fatal to mankind. The putrid fubftances, therefore, can only be ufed by mixing them with the earth ; and in whatever manner they can be moft per¬ fectly, and in the greateft quantity, mixed with the foil, there the beft crops may be expefted. Sect.III. Of the different Soils, and the Ma¬ nures moft proper for each. Ri theft foils According to the theory we have juft now laid muft at laft down, the richett foil muft be that which contains the be Impove- greateft quantity of putrid matter, either animal or ve- j-fthed. getable ; and fuch is the earth into which animal and vegetable fubftances refolve themfelves. Was this earth to be had in perfection, it is evident it could not ftand in need of manure of any kind, or be in the leaft enrich¬ ed by it; for containing an immenfe quantity of putrid matter, it would freely communicate it to the vegetables planted in it, which would grow in the moft luxuriant manner, without requiring any other care than that of keeping them conftantly fupplied with water. If we fuppofe the crop left upon the ground to putrefy and ■.mix with the earth as before, the foil will contain the fame quantity of putrid matter the fecond year that it did the firft, and be equally prolific: but if the crop is removed to another place, and nothing is brought back to enrich the ground in its Head, it is evident, that it will contain lefs of the true vegetable food the fecond year than it did the firft, and confequently be lefs prolific. For fome time, however, the difference L T U R E. Parti.; will not be perceptible ; and people who are in poffef- Theory, fion of fuch ground may imagine that they enjoy a foil which will be perpetually fertile ; but long expe¬ rience has taught us, that the richeft foils will at laft be exhaufted by repeated cropping without manure, as according to our theory they ought to be. Where the ground has been fuffered to remain un¬ cultivated for many ages, producing all that time fuc- culent plants which are eafily putrefied, and trees, the leaves of which likewife contribute to enrich the ground by their falling off and mixing with i.t, the foil will in a manner be totally made up of pure vegetable earth, and be the richeft, when cultivated, that can be ima¬ gined. This was the cafe with the lands of America. They had remained uncultivated perhapsTince the Crea¬ tion, and were endowed with an extraordinary degree . of fertility; neverthelefs we are affured by one who went to America in order to purchafe lands there, that fuch grounds as had been long cultivated, were fo much ex¬ haufted, as to be much worfe than the generality of cul- 25 tivated grounds in this country. Here, then, we have One fpecies an example of one fpecies of poor foil; namely, one ^fS-oved01*1 that has been formerly very rich, but has been deprived, j,y ];mye> by repeated cropping, of the greateft part of the vege¬ table food it contained. The farmer who is in poffef- fion of fuch ground, would no doubt willingly reftore it to its former ftate; the prefent queftion is, What muft be done in order to obtain this end ? We have men¬ tioned feveral kinds of manures which long practice has recommended as ferviceable for improving ground: we fhall fuppofe the farmer tries lime, or chalk; for, as we have already feen, their operations upon the foil muft be precifely the fame. This fubftance, being of a feptic nature, will aft upon fuch parts of the foil as are not putrefied, or but imperfeftly fo; in confequence 1 of which, the farmer will reap a better crop than for¬ merly. The feptic nature of the lime is not altered by any length of time. In ploughing the ground, the lime is more and more perfeftly mixed with it, and gradually exerts its power on every putrefcible matter it touches. As long as any matter of this kind remains, the far¬ mer will reap good crops: but when the putrefcible matter is all exhaufted, the ground then becomes per¬ feftly barren; and the cauftic qualities of the lime are moft unjuftly blamed for burning the ground, and re¬ ducing it to a caput mortuuni; while it is plain, the lime has only done its office, and made the foil yield all that it was capable of yielding. ^ When ground has been long uncultivated, producing A'fpecies of all the time plants, not fucculent, but fuch as are very poor foil difficultly diffolved, and in a manner incapable of pu- meliorated trefaftion; there the foil will be exceffively barren, and ^ imei yield very fcanty crops, tho’ cultivated with the greateft care. Of this kind are thofe lands covered with heath, which are found to be the moft barren of any, and the moft difficultly brought to yield good crops. In this cafe lime will be as ferviceable, as it was detrimental in the other: for by its feptic qualities, it will con¬ tinually reduce more and more of the foil to a putrid ftate; and thus there will be a conftant fucceffion of better and better crops, by the continued ufe of lime when the quantity firft laid on has exerted all its force. By a continued ufe of this manure, the ground will be gradually brought nearer and nearer to the nature of gar¬ den-mould ; and, no doubt, by proper care, might be 2 made *art I. Theory. *7., : ioiis, low refto- ed. A G R I C U made as good as any: but it will be as great a miftake to imagine, that, by the ufe of lime, this kind of foil may be rendered perpetually fertile, as to think that the other was naturally fo; for though lime enriches this foil, it does fo, not by adding vegetable food to it, but by preparing what it already contains ; and when all is properly prepared, it muft as certainly be exhauft- ed as in the other cafe. Here, then, we have examples of two kinds of poor foils; one of which is totally deftroyed, the other greatly improved, by lime, and which therefore require very different manures; lime being more proper for the laft than dung; while dung, being more proper to reftore an exhaufled foil than lime, ought only to be ufed for the firft. Befxdes dunging land which has been ex- haufted by long cropping, it is of great fervice to let it lie fallow for fome time : for to this it owed its ori¬ ginal fertility ; and what gave the fertility originally, cannot fail to reftore it in fome degree. By attending to the diftin&ion between the reafons for the poverty of the two foils juft now mentioned, We will always be able to judge with certainty in what cafes lime is to be ufed, and when dung is proper. The mere poverty of a foil is not a criterion whereby we can judge ; we muft confider what hath made it poor. If L T U R E. 255 that lime alone, upon a poor foil, will, in many cafes, Theory, produce a much greater and more lafting degree of fertility than dung alone.” Thus far Mr Anderfon’s experience is exaftly con¬ formable to the theory we have laid down, and what ought to happen according to our principles. He men¬ tions, however, fome fafts which feem very ftrongly to militate againft it; and indeed he himfelf feems to proceed upon a theory altogether different. “ Calcareous matter alone (fays he) is not capable Query con- of rearing plants to perfection ;—mould is necef- cerning the fary to be mixed with it in certain proportions,nature a before it can form a proper foil. It remains, ’ 01 * however, to be determined, whaf is the due pro¬ portion of thefe ingredients for forming a proper foil. “ We know that neither chalk, nor marie, nor lime, can be made to nourifh plants alone; and foils are fometimes found that abound with the two firft of thefe to a faulty degree. , But the proportion of calcareous matter in thele is fo much larger than could ever be produced by art, where the foil was naturally deftitute of thefe fubftances, that there feems to be no danger of erring on that fide. Probably it would be much eafier to correft the defeCts of thofe foils in which calcareous it is naturally fo, we may almoft infallibly conclude, that matters fuperabound, by driving earth upon them : Mr Ander¬ fon’s opini- ion concern- iing lime. it will become better by being manured with lime. If it is artificially poor, or exhaufted by continual crop¬ ping, we may conclude that lime will entirely de- ftroy it.—We apprehend, that it is this natural kind of poverty only which Mr Anderfon fays, in his Effays on is Agriculture, may be remedied by lime; for we can fcarce think that experience would dire& any perfon to put lime upon land already exhaufted. His words are, “ Calcareous matters a61 as powerfully upon land that is naturally poor, as upon land that is more richly impregnated with thofe fubftances that tend to produce a luxuriant vegetation.” “ Writers on agriculture have long been in the cu~ ftom of dividing manures into two claffes, viz. Enriching^ manures, or thofe that tended direftly to render the foil more prolific, hpwever fterile it may be; among the foremoft of which was dung: Exciting manures, or thofe that were fuppofed to have a tendency to render the foil more prolific, merely by aCling upon thofe enrich¬ ing manures that had been formerly in the foil, and giving them a new ftimulus, fo as to enable them to operate anew upon that foil which they had formerly fertilized. Ih which elafs of ftimulating manures, lime was always allowed to hold the foremoft place. “ In confequence of this theory, it would follow, that lime could only be of ufe as a manure when ap¬ plied to rich foils—and when applied to p6or foils, would produce hardly any, or even perhaps hurtful, effe&s. “ I will frankly acknowledge, that I myfelf was fo far impofed upon by the beauty of this theory, as to be hurried along with the general current of mankind, in the firm perfuafion of the truth of this obfervation, and for many years did not fufficiently advert to thofe fads that were daily occurring to contradict this theory.—I am now, however, firmly convinced, from manure, than is generally imagined ; as a very fmall proportion of it fometimes affords a very perfeft foil, I fhall illuftrate my meaning by a few examples. 3o " Near Sandfide, in the county of Caithnefs, there Examples pretty extenfive plain on the fea-coaft, endowedol foil per* with a moft Angular degree of fertility. In all feafons it produces a moft luxuriant herbage, although it never got any manure fince the creation; and has been for time immemorial fubjeCted to the following courfe of crops. “ I. Bear, after once ploughing from grafs,. ufually a good crop. “ 2. Bear, after once ploughing, a better crop than the firft. “ 3. Bear, after once ploughing, a crop equal,, to the firft. “ 4. 5. and 6, Natural grafs, as clofe and rich as could be imagined, might be cut, if the poffeffor fo inclined, and would yield an extraordinary crop of hay each year. “ After this the fame courfe of cropping is renewed. The foil that admits of this Angular mode of farming, , appears to be a pure incoherant fand, deftitute of the fmalleft particle of vegetable mould; but, upon exa¬ mination, it is found to confift almoft entirely of broken ftiells: the fine mould here bears fuch a fmall propor¬ tion to the calcareous matter, as to be fcarce percep¬ tible, and yet it forms the moft fertile foil that ever I yet met with. “ I have feen many other links (downs) upon the fea-fhore, which produced the moft luxuriant herbage, and the clofeft and fweeteft pile of grafs, where they confifted of Ihelly fand ; which, without doubt, derive their extraordinary fertility from that caufe. “ A very remarkable plain is found in the ifiand of Jir-eye, one of the Hebrides. It has been long em- repeated obfervations, that lime, and other calcareous ployed as a common; fo that it has never been difturb- manures, produce a much greater propdrtional improve¬ ment upon poor foils than fuch as are richer.—And ed by the plough, and affords annually the moft luxu¬ riant crop of herbage, confifting of white clover, and other 256 AGRICULTURE. Part L Theory, other valuable pafture-graffes, that can be met with any where. The foil confifts of a very pure flielly fand. “ From thefe examples, I think it is evident, that a very fmall proportion of vegetable mould is fufficient to render calcareous matter a very rich foil. Perhaps, however, a larger proportion may be necdlary when it is mixed with clay than with fand ; as poor chalky foils feem to be of the nature of that compofition. To thefe examples brought by Mr Anderfon, we may add fome of the fame kind mentioned by Lord Kames. His lordfhip having endeavoured to eltablilh the theory of water being the only food of plants, tho* he himfelf frequently deviates from that theory, yet thinks it poffible, upon fuch a principle, to make a foil .perpetually fertile. “ To recruit (fays he) with vegetable food, a foil impoverilhed by cropping, has hitherto been held the only objeft of agriculture. But here opens a grander objeft, worthy to employ our keeneft induftry, that of making a foil perpetually fertile. Such- foils actually exifl; and why Ihould it be thought, -that imitation here is above the reach of art ? Many are the inftan- ces of nature being imitated with fuccefs. Let us not defpair, while any hope remains; for invention never was exercifed upon a fubjeft of greater utility. The attempt may fuggeft proper experiments : it may open new views: and if we fail in equalling nature, may we not, however, hope to approach it? A foil perpetually fertile muft be endowed with a power to retain moilture fufficient for its plants; and at the fame time muft be of a nature that does not harden by moifture. Cal¬ careous earth promifes to anfwerboth ends: it prevents a foil from being hardened by water; and it may pro¬ bably alfo' invigorate its retentive quality. A field •that got a fufficient dofe of clay-marle, carried above 30 fucceffive rich crops, without either dung or fallow. Doth not a foil fo meliorated draw near to one per¬ petually fertile ? Near the eaft fide of Fife, the coaft for a mile inward is covered with fea-fand, a foot deep or fo ; which is extremely fertile, by a mixture of fea- ffiells reduced to powder by attrition. The powdered ffiells, being the fame with fhell-marle, make the fand retentive of moifture ; and yet no quantity of moifture will unite the fand into a folid body. A foil fo mix¬ ed, feems to be not far diftant from one perpetually fertile. Thefe, it is true, are but' faint effays ; but what will not perfeverance accompliffi in a good caufe t” Having thus, in a manner, pofitively determined with Mr Anderfon, that no dofe of calcareous matter can poffibly be too great, we cannot help owning our- ^ t felves furprifed on finding his Lordlhip expreffing him- Inconfiften- feT as follows : “ An over-dofe of ffiell-marle, laid per- cy in Lord haps an inch, and an inch and a half, or two inches Kiinns s thick, produces, for a time, large crops ; but at laft it renders the foil a caput mortuum, capable of neither corn nor grafs; of which there are too many inftances in Scotland ; the fame probably would follow from an over-dofe of clay-marle, ftone-marle, or pounded lime- ft°ne-”—To account for this, he is obliged to make a fuppofition directly contrary to his former one ; name¬ ly, that calcareous matter renders the foil incapable of retaining water. This phenomenon, however, we think is folved upon the principles, above laid down, in a fa- tisfa&ory manner, and without the leaft inconfiftency. As to rendering foils perpetually fertile,, we cannot help thinking the attempt altogether chimerical and Theory., vain. There is not one example in nature of a foil perpetually fertile, where it air, and the rain which falls „ cited examples can by no means be admitted as proofs foih chimel of perpetual fertility. We know, that the grafs on the ricul. j banks of a' river is. much more luxuriant than what grows at a diftance : the reafon is, that the water is at¬ tracted by the earth, and communicates its fertilizing qualities to it; but was the river to be dried up, the grafs would foon become like the reft. Why Ihould not the ocean have the fame power of fertilizing plains near its ffiores, that rivers have of fertilizing fmall fpots near their banks ? We fee, however, that it hath not; for the fea-lhores are generally fandy and barren. The reafon of this is, that the. waters of the ocean contain a quantity of loofe acid *; and this acid is poifonous to *S&tWater^ plants; but abftrafting this acid part, we hefitate not to affirm, that fea-water is more fertilizing than river- water. It is impoffible to know how far the waters of the ocean penetrate under ground through a fandy foil. Where they meet with nothing to abforb their acid, there the ground is quite barren ; but in palling through an jmmenfe quantity of broken Ihells, the cal¬ careous matter, we are very certain, will abforb all the acid; and thus the foil will be continually benefited by its vicinity to the ocean. Ail the above fields, there¬ fore, are evidently fupplied with nourilhment from the ocean': for if the falt-water has fufficient efficacy to render fields which are in its neighbourhood barren, why ffiould it not render them fertile when the caufe of barrennefs is removed from its waters ? After all, the field in Caithnefs, mentioned by Mr Anderfon, feems to have been perpetually fertile only in grafs; for though the fecond year it carried a better crop of bear than it did the firft, yet the third year the crop was worfe than the fecond, and only equal to the firft. Had it been ploughed a fourth time, the crop would probably have been worfe than the firft. Ground is not near fo much exhaufted by grafs as corn, even though the crop be cut, and carried off; and ftill lefs, if it only feeds cattle, and is manured by their dung; which appears to have been the cafe with this field. Lord Kames, indeed, mentions fields in Scotland, that, paft memory, have carried fucceffive crops of wheat, peafe, barley, oats, without a fallow, and without a ma¬ nure; and particularifes one on the river Carron, of nine or ten acres, which had carried 103 crops of oats without intermiffion, and without manure : but as we are not acquainted with any fuch fields, nor know any thing about their particular fituation, we can form no judgment concerning them. ^ f Befides the two kinds of foils above mentioned, there Clay and t\ are others, the principal ingredient of which is clay orf.mdy foils!; fand. The firft of thefe is apt to be hardened by the heat of the fun, fo that the vegetables can fcarce pe- , netrate it in fuch a manner as to receive proper nou- riffiment. The fecond, if it is not fituated fo as to re¬ ceive a great deal of moifture, is very apt to be parch- ed up in fummer, and the crop deftroyed; nor has it fufficient adhefion to fupport plants that have few roots and grow high. From thefe oppofite qualities, it is evident, that thefe two foils woul4 be a proper manure for one another; the clay would give a fufficient de¬ gree of firmnefs to the fand, and the fand would break tins has no fupply but from the _ 3* >: it. The above re-^u*S Part. I. A G R I C U Theory, the too great tenacity of the clay. According to Dr Home’s experiments, however, fand is the worit manure for clay that can be ufed. He recommends marie moft. To reduce clay-ground as near as poffible to the form of pure vegetable mould, it mufl. firll be pulverized. This is moft effe&ually performed by ploughing and harrowing; but care muft be taken not to plough it whilft too wet, otherwife it will concrete into hard clots which can fcarcely be broken. After it is pulverized, however, fome means muft be taken to keep it from concreting again into the fame hard maffes as before. According to Lord Karnes, though clay, after pulve* rization, will concrete into as hard a mafs as before, if mixed with water $ yet if mixed with dunghill juice, it will not concrete any more. Lime alfo breaks its tenaci* ty, and is very ufeful as a manure for this kind of foil. Fertility of The conclufion we wifh the practical farmer to draw the earth li- from our theory is, That there is a certain limit to the xnited. fertility of the earth, both as to duration and to de¬ gree, at any particular time : that the nearer any foil approaches to the nature of pure garden-mould, the nearer it is to the moft perfect degree of fertility ; but that there are no hopes of keeping it perpetually in fuch a ftate, or in any degree of approximation to it, but by conftant and regular manuring with dung. Lime, chalk, marie, &c. may be proper to bring it near to I, this ftate, but are abfolutely unfit to keep it continu¬ ally fo. They may indeed for feveral years produce large crops; but the more they increafe the fertility for fome years, the fooner will they bring on an abfo* lute barrennefs; while regular manuring with plenty of dung will always enfure the keeping up-the foil in good condition, without any occafion for fallow. What we have faid concerning the ufe of lime, &c. applies likewife to the practice of frequent ploughing, though in a lefs degree. This tends to meliorate ground that is naturally poor, by giving an opportunity to the ve¬ getable parts to putrefy; but when that is done, it tends to exhauft, though not fo much as lime. A ju¬ dicious farmer will conftantly ftrive to keep his lands always in good condition, rather than to make them fuddenlymuch better; left a few years fhould convince him that he was in reality doing almoft irreparable mif- chief, while he fancied himfelf making improvements. As for the ridiculous notions of ftimulating the ground by faline manures, we hope they will never enter the brain of any rational practitioner of agriculture. Sect. IV. Of the different kinds of Vegetables proper to be raifed with a view to the Meliora¬ tion of Soil. Soil pulve- The methods of meliorating foils, which we have fized by mentioned above, confifting of tedious and laborious certain ve- operations that yield no return at firft, it is natural for geta es. a farrner to wJfh for f0me method of meliorating his ground, and reaping crops at the fame time. One very confiderable ftep towards the melioration of ground is, its pulverization. This is accomplifhed by repeated ploughings (a), as already mentioned; efpecially ifper- xormed in autumn, that the ground may be expofed to Vql. I. Part I. L T U R E. 257 the winter’s froft; but thefe ploughings yield no crop Theory. as long as the field is not fown. By planting in the y J field, however, thofe vegetables whofe roots fwell to a confiderable bulk, the ground muft conftantly be afted upon by the fwelling of their roots in all direftions; and thus the growing of the crop itfelf may be equal, or fupe- rior, in efficacy to feveral ploughings, at the fame time that the farmer enjoys the benefit of it. The plant molt remarkable for the {welling of its roots is the potato; and by none is the ground meliorated more, or even fo much. They are not, however, equally proper for all foils. In clay they do not thrive, nor are palatable ; but in hard gravelly or fandy foils, they grow to a large fize, and are of an excellent quality. Turnips likewife contribute to meliorate the ground, by the fwelling of their roots, though not fo much as potatoes. They have this advantage, however, that they will thrive in almoft any foil. In clay ground, peafe and beans thrive exceedingly well, and therefore are proper in this kind of foil as a preparatory for other kinds of grain. Thefe pufh their roots deep into the ground, and cover it with their leaves more than other crops; fo that the fun has not fo much accefs as when it is covered with other kinds of grain. Wherever any of thefe kinds of vegetables are raifed, it is obfervable, that more or lefs blacknefs is communicated to the foil: an evident fign of its melioration ; this being the colour of the true vegetable mould, or loamy foil, as it is called. Befides the above-mentioned plants, carrots, parfnips, cabbages, and all thofe vegetables which fink their roots deep in the ground, anfwer the fame purpofe of loofening and pulverifing the earth; but as they will not thrive but on ground already well cultivated, they cannot be raifed to any advantage for the purpofe of meliorating a poor foil. It hath been cuftomary in many places, particular¬ ly in England, to fow turnip, peafe, buck-wheat, [&c. and then to plough them down for manuring the land. This being fimilar to that operation of nature by which {he renders the uncultivated foils fo exceedingly fertile, cannot fail of being attended with lingular ad¬ vantages ; and might be looked upon as preferable even to driving dung on the land to fatten it, was it not attended with the entire lofs of a crop for that year. Sect. V. Of defraying Weeds. What we have already faid regarding the cultivation of the foil, refpedts only the fitting it for producing all kinds of vegetables indiferiminately. Experience, however, fliows, that the ground is naturally much more difpofed to produce and nourilh fome kinds of vegetables than others; and thofe which the earth feems moft to delight in, are commonly fuch as are of very little ufe to man; but if nfeglefted, will increafe to fuch a degree, as entirely to deftroy the plants intended to be raifed, or at leaft hinder them from coming to perfection, by depriving them of nourilhment. The clearing the ground of weeds, therefore, is an article no lefs neceffary in agriculture, than the difpofing it to produce vegetables of any kind in plenty. K k The (a) This, however, muft be underftood with fome limitation: for it appears from experience, that many light and thin foils receive detriment rather than advantage from frequent ploughings; particularly in fummer, when'the fun exhales the nutritive particles in great abundance, A G C U Perennial weeds,how deftroyed. 38 Broom, 'furze, &c. how de¬ ftroyed. C I The weeds may be divided, according to the time of their duration, into annual, or fuch as fpring from a: feed, and die the fame year;, and perennial, that is, fuch as are propagated by the roots, and lail for a number of years. The firft kind are the leaft noxious, and molb eafily deftroyed. For this purpofe it will be fufficient to let them fpring up till near the time of ripening their feed, and then plough them down before it comes ttr maturity. It is alfo of fervice to deftroy fuch weeds as grow in borders, or neglefted corners,, and frequent¬ ly fcatter their feeds to a great diftance ; fuch as the thiftle, dandelion, rag-weed, &c.. for thefe are fufficient to propagate their fpecies through a deal of ground; as their feeds are carried about with the wind to very confiderable diftances. A farmer ought alfo to take care, that the fmall feeds of weeds, feparated from corn in winnowing, be not. fown again upon the ground; for this certainly happens when they are thrown upon a dunghill; becaufe, being the natural offspring of the earth, they are not eafily deftroyed. The beft method of preventing any mifchief from this caufe, would be to burn them. Perennial weeds cannot be effectually deftroyed, but by removing the roots from the ground, which is often a matter of ibme difficulty. Many of thefe roots ftrike fo deep in the ground, that they can fcareely be got out. The only method that can be depended upon in this cafe, is frequent ploughing, to render the ground as tender as- poffible ; and harrowing with a particular kind of harrow, v/hich fhall hereafter be defcribed, in order to colleft thefe pernicious roots. When collec¬ ted, they ought to be dried and burnt, as the only effectual method of infuring their doing no further mifchief. There is a particular fpecies of weed, peculiar only to grafs-lands, of a foft fpongy nature, called^S^, which it is found very difficult to exterminate. Where the land can be conveniently tilled, this weed may be deftroyed by covering k with a crop of peafe, potatoes, &c. or, paffing a heavy roller over the gound will be of great fervice; for fog owes its origin to too great a laxity of the foil, and wilLnot grow upon firm ground. Befides thefe kinds of weeds which are of an herba¬ ceous- nature, there are others which are woody, and grow to a very confiderable fize; fuch as broom, furze or whins, and thorns. Broom is an evergreen fttrub, that thrives beft in fandy foil; and there it grows fo vi- goroufly, as fcarce to admit any grafs under it. It pro¬ pagates by feed which grows in pods; and thefe, when fully ripe, break with violence, fcattering the feeds all around. Thus, a field which is overgrown with broom, befides the old plants, always contains an in¬ finite number of young ones; fo that though the old plants die when cut over, a frefh crop conftantly fprings up. It may, however, be deftroyed by frequent plough¬ ing and harrowing, in the fame manner as other peren¬ nial weeds are; for it does not for fome time carry any feed, and the frequent ploughing encourages the vege¬ tation of all thofe that are already in the ground, which cannot fail of being deftroyed by frequent repetitions of the operation. Another method of deftroying broom, is by pafturing the field where it grows with fheep. A few of the old bullies may be left as a Ihelter, and thefe will be in a good meafure prevented from fpreading by the cropping of the Iheep. Thefe animals are very fond L T U R E. Part. E of broom, and greedily devour every young Ihoot; fo Theory. , that if any remain after the firft year, there will not be “ a veftige the fecond. If this method of extirpating broom is equally effectual with that of frequent plough¬ ing, it is certainly much more profitable, as there is no food more nourilhing to Iheep than young broom. Broom, however, is faid to have a fingular effedf upon fheep : it makes them drunk fo effectually, that when heated with a little driving, they tumble over, and lie without motion. The ’whin is a fine evergreen Ihrub, carrying a fweet- fmelling flower all the year round. It propagates both by feed and by its roots, which fpread fometimes to the diftance of 10 or 12 feet; and hence, when once efta- blifhed, it is with difficulty extirpated. The beft me¬ thod is to fet fire to the whins in frofty weather; for froft has the eftedt to wither whins, and make them burn readily. The Humps muft then be cut over with a hatchet; and when the ground is well foftened by rain, it may be ploughed up, and the roots taken out by a harrow adapted to that purpofe. If the field is foon laid down to grafs, the whins will again fpring up in great abundance, from the feeds, and fmall parts of the roots left in the ground. In this cafe, pafturing with flieep is an effectual remedy ; as they are no lei’s fond of young whins than of young broom; and if there are a fufficient number, they will not leave a Angle plant above ground. But if grafs is not imme¬ diately wanted, the moft effectual method of clearing a field of whins, .is by reiterated ploughings. The thorn, or bramble, fpreads its roots very wide, and at the fame time finks them deep in the earth. Though cut in the winter, ft rifes, and comes to fuch perfection as to carry fruit in fummer. It can only be extirpated by ploughing up the ground, and collec¬ ting the roots. Sect.VI. Of the mojl proper kinds of Vegetables to be raifed for the purpofes of feeding Cattle. Though this muft be an article of the utmoft con- fequence to every farmer, we do not find that it has been much confidered. Mr Anderfon feems to have been the firft writer on agriculture who hath properly attended to this fubjeft ; and what he hath wrote upon it, is rather a catalogue of defiderata, than any thing elfe : and indeed the defiderata on this fubjedt are fo many and fo great, that we muft acknowledge ourfelves very un¬ able to fill them up.— To attain to a competent knowledge in this refpeft, the following things muft beQyjj-^e, c.f ij taken into confideration. ( i.) The wholefomenefs of the food re- the food for cattle, with regard to health and ftrength, qoifite foi- |! or fatnefs. (2.) The quantity that any extent,ofcaU*e‘ ground is capable of yielding. (3.) The quantity ne- ceffary to feed the different kinds of cattle. (4.) The labour of cultivation; and, (5.) The foil they require to bring them to perfection, and the effedt they have upon it. With regard to the wholefomenefs, it is plain, that as the natural food of wild cattle is the green fucculent plants they meet with all the year round, food of this kind, could it be had, muft be preferable to hay ; and accordingly we find that cattle will always prefer fuc¬ culent vegetables where they can get them. To find AGRICULTURE. 359 plants of tliis kind, and having proper qualities in o- giving putrefcent food to his cattle. It is well known, Theory. J ther refpedts, we muft fearch among thofe which con- what a prodigious difference there is in the health of' 1 ~' tinue green all the year round, or come to their great- the human fpecies when fed on putrid meats, in .conrw eft perfeftion in the winter-time.—Of thefe, cabbages parifon of what they enjoy when fupplied with food of bid fair for holding the firft place ; both as being very a contrary nature ; and why may there not be a dif- fucculent, and a very large quantity of them growing ference in the health of beafts, as well as of men, when upon a fmall fpace of ground. In Mr Young’s Six in fimilar circumftances ?—It is alfo very probable,, Months Tour, we have an account of the produce of that as carrots are more folid than cabbages or tur- cabbages in many different places, and on a variety of nips, they will go much farther in feeding cattle than foils.

Horfes are very fond of the grain ; poultry of all forts are fpeedily fattened by it; and the bloffom of the plant affords food for bees at a very opportune feafon of the year, when the meadows and trees are moftly ftripped of their flowers. Probably the grain may hereafter be even found a ma¬ terial article in diflillation, fhould a fufficient quantity be raifed with that view. From the fuccefs of fome experiments detailed in the Bath Society Papers, and for which a premium was beftowed, it has been infer¬ red, that this article ought in numerous cafes to fuper- fede the practice of fummer-fallowing. Whins have lately been recommended as a very pro¬ per food for cattle, efpecially horfes ; and are recom¬ mended by Mr Anderfon in a particular manner. They have this advantage, that they require no culture, and grow on the very worfl: foil; but they are trouble- fome to cut, and require to be bruifed in a mill con- ftrutted for this purpofe ; neither is the ground at all meliorated by letting whins grow upon it for any length of time. Notwithftanding thefe difadvantages, how¬ ever, as whins "continue green all the year round, and when bruifed will afford an excellent fucculent food, which feems pofleffed of itrongly invigorating qualities, they may be looked upon as the cheapeft winter-food that can poffiblybe given to cattle.—According to the calculations of Mr Eddifon of Gateford, a Angle acre, well cropped with whins, will winter Ax horfes : at three or four years growth, the whole crop fhould be taken, cut clofe to the ground, and carried to the mill; in which the whins are to be bruifed, and then given to the horfes. Four acres ought to be planted, that one may be ufed each year, at the proper age to be cut; and he reckons the labour of one man fuffi¬ cient for providing food to this number of horfes. He fays they all prefer the whins to hay, or even to corn. The herb called burnet hath likewife been recom¬ mended as proper food for cattle, on account of its being an evergreen ; and further recommended, by growing almoft as faff in winter as in fummer. Of this herb, however, we have very various accounts. In a letter addrefled by Sir James Caldwell, F. R. S. to the Dublin Society, the culture of this plant is ftrongly recommended' on the authority of one Bartholomew Rocque, farmer at Walham-Green, a village about three miles fouth-weft of London. What gave occaAon to the recommendation of this plant, was, that about the year 1760., Mr Wych, chair¬ man of the committee of Agriculture of the London Society for the encouragement of arts, manufaftures, and commerce, came to Rocque ( who was become very eminent by the premiums he had received from the fo- ciety), and told him, he had been thinking, that as there are many animals which fubflll wholly upon the fruits of the earth, there muft certainly be fome plant or herb At for them that naturally vegetates in winter; otherwife we mull believe the Creator, inAnitely wife and good,. to have made creatures without providing for their fubfiftence : and that if there had been no fuch plants or herbs, many fpecies ,of animals would have perifhed before we took them out of the hands of nature, and provided for them dry meat at a feafon, when, indigenuous plants having been indifcriminately 4; excluded, under the name of weeds, from cultivated Theory. Aelds and places fet apart for natural grafs, green or ' v'~"’ freflr meat was no longer to be found. Rocque allowed the force of this reafoning ; but faid, the knowledge of a grafs, or artiflcial pallure, that would vegetate in winter, and produce green fodder for cattle, was loft ; at leaft, that he knew of no fuch plant.—Mr Wych, however, knowing how very great the advantage would be of difcovering a green fodder for winter and early in the fpring, wrote to Bern, and alfo to fome conftderable places in Sweden, ftating the fame argument, and afliing the fame queftion. His an- fwers to thefe letters were the fame that had been given by Rocque. They owned there muft be fuch plant, but declared they did not know it. Mr Wych then applied again to Rocque ; and defl- red him tofearch for the plant fo much deftred, and fo. certainly exifting. Rocque fet about this fearch with great afliduity; and ftnding that a pimpernel, called burnet, was of very fpeedy growth, and grew near as fall in winter as in fummer, he took a handful of it and carried it into his liable, where there were five hor¬ fes ; every one of which eat of it with the greateft eager- nefs, fnatching it even without firft fmelling it. Upon the fuccefs of this experiment he went to London, and bought all the burnet-feed he could get, amounting to no more than eight pounds, it having been only ufed in falads; and he paid for it at the rate of 4 s. a pound. Six of the eight pounds of feed he fowed upon half an acre of ground, in March, in the year 1761, with a quarter of a peck of fpring-wheat, both by hand. The feed being very bad, it came up but thin. However, he fowed the other two pounds in the beginning of June,. upon about Ax rood of ground : this he mowed in the beginning of Auguft ; and at Michaelmas he planted off the plants on about 20 rood of ground, giving each plant a foot every way, and taking care not to bury the heart. Thefe plants bore two crops of feed the year following; the firft about the middle of June, the fecond about the middle of September ; but the June crop was the bell. The year after, it grew very rank, and produced two crops of feed, both very good. As it ought not to be cut after September, he let it Hand till the next year; when it Iheltered itfelf, and grew very well during all the winter, except when there was a hard froft; and even during the froft it continued green, though it was not perceived to grow. In the March following it covered the ground very well, and ; was fit to receive cattle. If the winter is not remarkably fevere, the burnet,, though cut in September, will be 18 inches long in . March; and it may be fed from the beginning of Fe¬ bruary till May: if the cattle are taken, off in May,. there will be a good crop of feed in the beginning of July. Five weeks after the cattle are taken off, it may be removed, if that is preferred to its Handing for feed; . it grows at the rate of an inch a-day, and is made into . hay like other grafs. It may be mown three times in one fummer, and Ihould be cut juft before it begins to flower. Six rood of ground has produced 1150 pounds at the firft cutting of the third year after it was fowed ; and, in autumn 1763, Rocque fold -no lefs than 300 , bulhels of the feed. According to Rocque, the foil in which burnet flou-~ rifhes heft, is a dry gravel; the longeft drought never hurts;. I Fart I.

It has even been afferted, that this root affords lefs nourifhment than any of thofe that have been commonly employed for feeding cattle. This does not correfpond with the pompous accounts with which the public has been en¬ tertained.

White beet Upon the authority of Mr Rocque, likewife, the for cows; that it vegetates during the whole winter, confequently is very forward in the fpring ; and that the moft profitable way of feeding cows is, to mow this . herb, and give it to them green, all the fummer. It grew in Rocque’s-garden, during a very great drought, no lefs than four feet high, from the 30th of May to judge what might be the value of a field of . grafs of this kind in thefe circumftances.” ^ Of another kind of grafs, called purple fefcue, Mr Purple f „ .. Anderfon gives the following character. “ It retain- cue- ed its verdure much better than rye-grafs during the winter-feafon ; but it had more of its points killed by the 3d of July; which is no more than one month and the weather than the former. It likewife rifes in the Root of Scarcity, four days. In fummer it grows more than an inch a- day,. and is beft fown in March : a buftiel is enough for an acre, and will not coft more than ten {hillings. It thrives beft in a rich, deep, light foil: the ftalks are very thick and fucculent; the cows ftiould therefore eat them green.. Another fpecies of beet (Beta cicla), the Mangel Wurzel, or Root of Scarcity, as it has been called, has fpring, at leaft as early as rye*grafs.” This ingenious farmer has alfo made experiments on the culture of thefe and feveral other kinds of graf- fes; which being very well worthy of attention, we {hall here infert. 1. Purple fefcue-grafs. “Although this grafs is very often found in old paftures, yet as it has but few flower- ftalks, and as it is greedily eat by all domeftic animals, been lately extolled as food both for man and cattle ; thefe are feldom fuffered to appear ; ,fo that it ufually but, after all, feems only to deferve attention in the latter view. It is a biennial-plant; the root is large and flefhy, fometimes a foot in diameter. It rifes above the ground feveral inches, is thickeft at the top, taper¬ ing gradually downward. The roots are of various colours, white, yellow, and red ; but thefe laft are al¬ ways of a much paler colour than beetrave. It is good fodder for cows, and does not communicate any tafte to the. milk. It produces great abundance of leaves remains there unperceived. But it feems to be better able to endure the peculiar, acrimony of the dung of dogs than almoft any other plant; and is therefore of¬ ten to be met with in dog-hills, as I call the little hills by road-fides where dogs ufually pifs and dung: and as it is allowed to grow there undifturbed, the farmer may have an opportunity of examining the plant, and , becoming acquainted with its appearance. “ The leaves, are long and fmall, and appear to be round!£h,. J2<)2 AGRICULTURE. Parti. Theory, roundifh, fometliing like a wire ; but, upon examina- ' v——' tion, they are found not to be tubulated like a reed or ru(h ; the Tides of the leaf being only folded together from the middle rib, exactly like the ftrong bent-grafs on the fea-fhore. The flower-ftalk is fmall, and branches out in the head, a little refembling the wild-oat; only the grains are much fmaller, and the ear does not fpread full open, but lies bending a little to one fide. The ftalks are often fpotted with reddifh freckles, and the tops of the roots are ufually tinged with the fame co¬ lour ; from whence it has probably obtained its diftinc- tivename of Fefhica rubra, or red [purple) fefaie. “ It is often to be met with in old garden-walks; and, as its leaves advance very quickly after cutting, it may ufually be difcovered above the other gralfes, about a week or fortnight after the walks are cut. Nor do they feem to advance only at one feafon, and then ftop and decay, like the rye-grafs; but continue to advance during the whole of the fummer, even where they are not cut; fo that they fometimes attain a very great length. Laft feafoni, (1774,)! meafured a leaf of this grafs, that fprung up in a neglefted corner, which was four feet and four inches in length, although not thicker than a fmall wire. It is unnecelfary to add, that thefe leaves naturally trail upon the ground, unlefs where they meet with fome accidental fupport; and that if any quan¬ tity of it is fuffered to grow for a whole feafon, with¬ out being eat down or cut, the roots of the leaves are almoft rotted, by the overfhadowing of the tops of the other leaves, before the end of the feafon. Appearance “ This is the appearance and condition of the plant in its culti- in its native fituation : as it Is feldom that it is difco- vated Hate, vered but in pretty old paftures, and as irt that ftate it carries only a very few feed-ftalks, it was with fome difficulty that I could celleft a fmall handful of the feed, which I carefully fowed in a fmall patch of garden- mould, to try if it could be eafily.cultivated. It came up as quickly as any other kind of grafs, but was at firft: as fmall as hairs: the leaves, however, advanced a- pace ; and were, before autumn, when the grain with which they had been fowed was cut down, about 16 or 18 inches in length: but having been fown very thin, it was neceffary to pick out fome other kinds of grafs that came up amongft it, left it might have been choaked by them. Early next fpring it advanced with prodigious A’igour, and the tufts that were form¬ ed from every .feed became exceeding large; fo that it quickly filled the whole ground. But now the leaves were almoft as broad as thofe of common rye-grafs, and the two fides only inclined a little towards one another from the mid-rib, without any appearance of roundnefs. In due time a great many feed-ftalks fprung out, which attained very nearly to the height of four feet, and produced feeds in abundance ; v/hich may be .as eafily faved as thofe of common rye-grafs. “ The prodigious difference between this plant in its native and cultivated ftate amazed me ; but it was with a good deal of fatisfa&ion that I found there would be no difficulty of procuring feeds from it, which I had much doubted of at firft. It would feem, that nature hath endowed this plant with a ftrong generative power during its youth, which it gradually lofes as it advan¬ ces in age (for the difference perceived in this cafe could not be attributed to the richnefs of the foil); and.that, on the contrary, when it was old, the leaves advanced with an additional vigour, in proportion to Theory, the declining ftrength of the flower-ftalks: for the 'r—J. leaves of the young plant feldom exceed two feet, whereas numbers of the old leaves were near four feet in length. “ From thefe peculiarities in the growth of this plant, it would feem to promife to be of great ufe to the far¬ mer; as he could reap from a field of it, for the firft two or three years, as great a weight of hay as he could obtain from any of the culmiferous graffes (thofe bearing a long jointed ftalk) ; and, if he meant afterwards to pafture it, he would fuffer no inconveniences from the flower-ftalks; and the fucculent leaves that continue to vegetate during the whole fummer, would at all times furnilh his cattle with abundance of wholefome food. It has alfo been remarked, that this grafs rifes as early in the fpring as rye grafs; and continues green for the greateft part of winter, which the other does not. It is moreover an abiding plant, as it feems never to wear out of the ground where it has once.been eftablifhed. On all which accounts, it appears to me highly to me¬ rit the attention of the farmer; and well deferves to have its feveral qualities, and the culture that beft agrees with it, afeertained by accurate experiments. s$ 2. “ Sheeps fefeue grafs, or fejluca ovina, is much Sheeps fef- praifed by the Swedifh naturalifts for its Angular value as cue deferi- a pafture-grafs for {keep ; this animal being reprefent- e * ed as fonder of it than of any other grafs, and fatten¬ ing upon it more quickly than on any other kind of food whatever. And indeed, the general appearance of the plant, and its peculiar manner of growth, feems very much to favour the accounts that have been given •us of it. “ This plant is of the fame family with the former, and agrees with it in feveral refpefts; although they may be eafily diftinguifhed from one another. Its leaves, like the former, in its natural ftate, are always rounded, but much fmaller; being little bigger than large horfe-hairs, or fwines-briftles, and feldom exceed fix or feven inches in length. But thefe fpring out of the root in tufts, fo clofe upon one another, that they refemble, in this refpeft, a clofe hair-brufh more than any thing elfe I know : fo that it would feem natural¬ ly adapted to form that thick ftiort pile of grafs in which ftieep are known chiefly to delight. Its flower- ftalks are numerous, and fometimes attain the height of two feet; but are more ufually about 12 or 15 inch- es hi£h' . , . .57 “ Upon gathering the feeds of this plant, and fowingits appear- them as the former, it was found that they fprung up ance when as quickly as any other kind of grafs ; but the leaves cuhivated. are at firft no bigger than a human hair. From each fide fprings up one or two of thefe hair-like filaments, that in a ftiort time fend out new off-fets, fo as quickly to form a fort of tuft, which grows larger and larger, till it at length attains a very large fize, or till all the intervals are clofed up, and then it forms the clofeft pile of grafs that it is poffible to imagine. In April and May it pufhed forth an innumerable quantity of flower-ftalks, that afforded an immenfe quantity of hay; it being fo clofe throughout, that the feythe could fcarcely penetrate it. This was allowed to ftand till the feeds ripened; but the bottom of the ftalks were quite blanched, and almoft rotted for want of air before that time. << This Part L w a [ycr. P AGRICULTURE. 26 “ This was the appearance that it made the firit year after it was fowed ; but I have reafon to think, that, af¬ ter a few years, it likewife produces fewer feed-ftalks, and a greater quantity of leaves than at fir ft. But however that may be, it is certain, that if thefe are eat down in the fpring, it does not, like rye-grafs, perfift in a continued tendency to run to feed; but is at once determined to pufti forth a quantity of leaves without almoft any ftalks at all: and as all domeftic animals, but more efpecially fheep, are extremely fond of this grafs, if they have liberty to pafture where it grows, they bite it fo clofe as never to fuffer almoft a Angle feed- ftalk to efeape them; fo that the botanift will often fearch in vain for it, when he is treading upon it with his feet. The heft way to difeover it in any pafture, is to fearch for it in winter, when the tufts of it may be ealily diftinguifned from every other kind of grafs, by their extraordinary clofenefs, and the deep green colour of the leaves. “ It feems to grow in almoft any foil; altho’ it is ima¬ gined that it would flourifti beft in a light fandy foil, as it can evidently live with lefs moifture than almoft any other kind of grafs; being often feen to remain in the fods that have been employed in coping for ftone- dykes, after all the other graffes that grew in them have difappeared. It is likewife found in poor barren foils, where hardly any other plant can be made to grow at all; and on the furface of dry worn-out peat-mofs, where no moifture remains fufficient to fupport any o- ther plant whatever: but in neither of thefe fituations does it thrive ; as it is there only a weak and unfxghtly plant, very unlike what it is when it has the good for¬ tune to be eftabliftied upon a good foil; although it is feldomer met with in this laft ftate than in the former. “ I will not here repeat what has been already faid about the particular property that this plant poflelfcs of continuing all winter ; nor point out the benefits that the farmer may reap from this valuable quality.— He need not, however, expect to find any verdure in winr ter on fuch plants as grow upon the loofe mofly foil above-mentioned; for, as the froft. in winter always hoves up the furface of this foil, the roots of the plants are fo lacerated thereby, as to make it, for fome time in the fpring, to all appearance dead. Nor will he of¬ ten perceive much verdure in winter upon thofe plants that grow upon poor hungry foils, which cannot afford abundant nourifhment to keep them in a proper ftate of .vegetation at all times : but. fuch plants as grow on earthen dykes, which ufually begin to vegetate with vigour when the autumnal rains come on, for the moft part retain their verdure at that feafon almoft as well as if they were in good garden-mould. “ I have been very particular in regard to this plant; becaufe, in as far as my obfervations have yet gone, it promifes on many accounts to make a moft valuable ac- quifition to the farmer, and therefore juftly demands a very particular {hare of his attention.” 3. The holcus lanatus> or creeping foft-grafs of Hud- fon.—This is confidered by our author as one of the moft valuable kinds of meadow-graffes; its pile being exceedingly clofe, foft, and fucculeht. It delights much in moifture, and is feldom found on dry ground, unlefs the foil is exceeding rich. It is often found on thofe patches near fprings, over which the water fre¬ quently flaw's; and may be known by the uncommon 2 foftnefs and fucculence of the blade, the lively light Theory, green colour of the leaves,, and the matted intertexture v of its roots. But, notwithftanding the foftnefs of its firft leaves, when the feed-ftalks advance, they are rough to the touch, fo that the plant then affumes a very dif¬ ferent appearance from what we would have expedled. The ear is' branched out into a great number of fine ra¬ mifications fomewhat like the oat, but much fmaller.— This kind of grafs, however, would not be eafily culti¬ vated, on account of a kind of foft membrane that makes the feeds adhere to the ftalk, and to one another, after they are feparated from it, as if they were inter¬ mixed with cobweb, fo that, it is difficult to ge.t them feparated from the ftalk,'or tofpread readily in fowing. It fpreads, however, fo faft by its running roots, that a fmall quantity fowed very thin, would be fufficient t® ftock a large field.in a ftiort time.. Thefe. are the kinds, of grajfes, properly fo called, which have not as yet been cultivated, that Mr An- derfon thinks the moft likely to be of value; but, be- fides thefe,. he recommends the following, of tire pea- tribe. (,0 I* Milk-vetch, liquorice-vetch, or milkwort. This Milk-vetcr plant, in fome refpefts, very much refembles the com¬ mon white clover; from-the top of the root a great number of ftioots come out in the fpring, fpreading a- long the furface of the ground every way around it ; from which arife a great many clutters of bright yel¬ low flowers, exaftly refembling thofe of the common broom. Thefe are fueceeded by hard round pods, fil¬ led with fmall kidney-fhaped feeds. From a fuppofed refemblance of a clufter of thefe pods to the fingers of an open hand,, the plant has been fometimes called ladies-fingers. By others it is called crow-toes, from a fancied refemblance of the pods to the toes of a bird. Others, from the appearance of the bloffom, and the part where the plant is found, have called it feal, im- . properly fell-broom. It is found plentifully almoft e- very where in old grafs-fields ; -but as .every fpecies of domeftic animals eat .it, almoft,in preference to any o- ther plant, it is feldom allowed to come to the flower in pafture-grounds, unlefs where they have been acci¬ dentally faved from the cattle for fome time ; fo that it. is only about the borders of corn-fields, or the fides of inclofures to which cattle have not accefs, that we have an opportunity, of obferving. iu As it has been imagined that the cows which feed on-thefe paftures, where this plant abounds, yield a quantity of rich milk, the plant has, from that circumftance, obtained its moft proper Englifti name of milk-vetch. gr One of the greateft recommendations of this, plant Its good is, that it grows in poor barren ground, where almoft 4- AGRICU LTURE. Part I.t , Theory- to cover the earth with the clofeft and mcft beautiful 'v carpet that can be defired. The flalks of the milk-vetch are weak and flender, To that they fpread upon the furface of the ground, nn- lefs they are fupported by fome other vegetable. In ordinary foils they do not grow to a great length, nor produce many flowers; but in richer fields the Talks grow to a much greater length, branch out a good deal, but carry few or no flowers or feeds. From thefe qualities our author did not attempt at firll to cultivate it with any other view than that of pafture; and, with this intention, fowed it with his ordinary hay feeds, expefting no material benefit from it till he defifted from cutting his field. In this, however, he was a- greeably difappointed ; the milk-vetch growing, the firft feafon, as tall as his great clover, and forming ex¬ ceeding fine hay; being fcarce diftinguilhable from lu¬ cerne, but by the flendernefs of the ftalk, and propor¬ tional fmallnefs of the leaf. Another recommendation to this plant is, that it is ’perennial. It is feveral years after it is fowed before it attains to its full perfe&ion ; but, when once efta- blifiled, it probably remains for a great number of years in full vigour, and produces annually a great quantity of fodder. In autumn 1773, Mr Anderfon cut the ftalk from an old plant that grew on a very in¬ different foil; and after having thoroughly dried it, he found that it weighed 14 ounces and a half. The ftalks of this plant die down entirely in winter, and do not come up in the fpring till the fame time ’that clover begins to advance ; nor does it advance ve¬ ry faft, even in fummer, when once cut down or eat over : fo that it feems much inferior to the abovemen- tioned graffes; but might be of ufe to cover the worft parts of a farm, on which no other vegetable could 62, thrive. ’Yellow 2. The commonyelhv) vetchling,(Lathyrus pratenjis') vetchling. or everlajiing tare, grows with great luxuriance in ftiff clay foils, and continues to yield annually a great weight of fodder, of the very beft quality, for any length of time. This is equally fit for pafture, or hay; and grows with equal vigour in the end of fum¬ mer as in the beginning of it; fo would admit being paftured upon in the fpring, till the middle, or even the end of May, without endangering the lofs of the crop of hay. This is an advantage which no other plant except clover poffeffes ; but clover is equally un¬ fit for early pafture or for hay. Sain-foin is the only plant whofe qualities approach to it in this refpeft, and the yellow vetchling will grow in fuch foils as are ut¬ terly unfit for producing fain-foin.—It is alfo a peren¬ nial plant, and increafes fo faft by its running roots, that a fmall quantity of the feed would produce a fuf- ficient number of plants to fill a whole field in a very ihort time. If a fmall patch of good ground is fowed with the feeds of this plant in rows, about a foot di- ftance from one another, and the intervals kept clear of weeds for that feafon, the roots will fpread fo much as to fill up the whole patch next year; when the ftalks may be cut for green fodder or hay. And if that patch were dug over in the fpring following, and the roots taken out, it would furnifti a great quantity of plants, which might be planted at two or three feet diftance from one another, where they would probably overfpread the whole field in a ftiort time. No 7. 3. The common blue tare feems more likely than Theory. ; the former to produce a more nourilhing kind of hay,' as it abounds much more in feeds; but as the ftalks B;ue come up more thinly from the root, and branch more above, ifdoes not appear to be fo well adapted for a pafture-grafs as the other'. The leaves of this plant are much fmaller, and more divided, than thofe of the other ; the ftalks are likewife fmaller, and grow to a much greater length. Though it produces a great quantity of feeds, yet the fmall birds are fo fond of them, that, unlefs the field was carefully guarded, few ■ J of them would be allowed to ripen. ^ II 4. The Vicia fepium, purple everlajiing, or bujh-vetch. Bulh-vetcMj Our author gives the preference to this plant beyond all others of the fame tribe for pafture. The roots of it fpread on every fide a little below the furface of the ground, from which, in the fpring, many ftems ;|] arife quite clofe by one another 5 and as thefe have a broad tufted top covered with many leaves, it forms as clofe a pile as could be defired. It grows very quick¬ ly after being cut or cropt, but.does not arrive at any great height; fo that it feems riiore proper for paftu- rage than making hay; altho’, upon a good foil, it will grow fufliciently high for that purpofe ; but the ftalks grow fo clofe upon one another, that there is great dan¬ ger of having it rotted at the root, if the feafon ftiould prove damp. It feems to thrive beft in a clay foil. , - Befides thefe, there are a variety of others of the fame EvcrlaflinJir clafs, which he thinks might be ufeful to the farmer, pea. The common garden everlafting pea, cultivated as a flowering-plant, he conje&ures, would yield a prodi¬ gious weight of hay upon an acre; as it grows to the height of ten or twelve feet, having very ftrong ftalks, that could fupport themfelves without rotting till they attained a great height. ^ |i One other plant, hitherto unnoticed, is recommend-Achillxa ed by our author to the attention of the farmer; it millefolium is the common yarrow, (Achillea millefolium), or hundred- leaved grafs. Concerning this plant,' he remarks, that, in almoft every fine old pafture, a great proportion of the growing vegetables with which the field is covered, confifts of it; but the animals which feed there are fo fond of the yarrow, as never to allow one feed-ftalk of it to come to perfection. Hence thefe feed-ftalks are never found but in negleCted corners, or by the fides of roads; and are fo difagreeable to cattle, that they are never tafted ; and thus it has been erroneoufly thought that the whole plant was refufed by them. — The leaves of this plant have a great tendency to grow very thick upon one another, and are therefore peculiarly adapted for pafturage. It arrives at its greateft perfection in rich fields that are naturally fit for producing a large and fucculent crop of grafs. It grows alfo upon clays; and is among the firft plants that ftrike root in any barren clay that has been lately dug from any confi- derable depth; fo that this plant, and thiftles, are ufual- ly the firft that appear on the banks of deep ditches formed in a clayey foil. All animals delight to eat it; but, from the dry aromatic tafte it poffeffes, it would feem peculiarly favourable to the conftitution of ftieep. It feems altogether unfit for hay. ^ Befides thefe plants, which are natives of our own>iirUcerfiejh, country, there are others, which, though natives of a foreign climute, are found to thrive very well in Bri¬ tain ; and have been raifed with fuch fuccefs by indi- | viduals, 11 A G R I c u viduals, as highly to merit the attention of every fanner. ' Among thefe the fir it place is claimed by lucerne. This is the plant called medica by the ancients, be- Caufe it came originally from Media, and on the culture of which they bellowed fuch great care and pains. It hath a perennial root, and annual ftalks, which, in good foil, rife to three feet, or fometimes more in height; its leaves grow at a joint like thofe of clover ; the flowers which appear in June, are purple, and its pods of a ferew-like fhape, containing feeds which ripen in Sep¬ tember. All forts of domeilic cattle are fond of this plant, efpecially when allowed to eat it green, and black L T U R.

Dr Home, in his Principles of Agriculture and Vegetation,claflesthe/mui in grain among the difeafes arifing from this caufe. He is of opinion, that too great an abundance of juices in a vegetable will produce difeafes fimilar to thofe occa- cattle may be fed very well with the hay made from jt; fioned by repletion in animal-bodies; viz. ftagnations, 68 Timothy- but an excefsof this food isfaid to be very dangerous. Lucerne has the property of growing very quickly after it is cut down, infomuch that Mr Rocque has mowed it five times in a feafon, and Mr Anderfon af¬ firms he has cut it no lefs than fix times. It is, how¬ ever, not very eafily cultivated; in confequence of which it fometimes does not fucqeed 5 and as it dies entirely in the winter, it is perhaps inferior to the fefeue graffes already mentioned, which, tho’ defpifed and neglefted, might probably yield as rich a crop as lucerne, with¬ out any danger of a mifearriage. Another grafs was brought from Virginia, where it , is a native, and fown by Rocque in 1763. This grafs is called Timothy, from its being brought from New- York to Carolina by one Timothy Hanfon. It grows heft in a wet foil; but will thrive in almofi: any. If it is fown in Auguft, it will be fit for cutting in the latter end of May or beginning of June. Horfes are very fond of it, and will leave lucerne to eat it. It is alfo preferred by black cattle and fheep; for a fquare piece of land having been divided into four equal parts, and ; part fowed with lucerne, another with fain-foin, a corruptions, varices, cariofities, See. along with the too great luxuriancy we have juft now mentioned, which he expreffesby “ too great an abundance of wa- ter-flioots.” Hence he is induced to clafs the fmut a- mong difeafes arifing from this caufe ; it being a cor¬ ruption happening moft in rainy; feafons, and to weak grain.—Like other contagious difeafes, he tells us, the fmut may be communicated from the infetted to health- yt ful grain. As a preventative, he recommends fteeping How pro* the grain in a ftrong pickle of fea-falt. Befides the ef- vcnted- fedt which this has upon the grain itfelf, it is ufeful for feparating the good from the bad; the beft feed falling to the bottom, and the faulty'fwimming on the top of the liquor.—For the fame purpofe, a ley of wood-aihes and quicklime is recommended by fome; and, byothers, a folution of faltpetre or copperas; after which the grain is to be dried with flacked lime, or dry turf aihes. This folution, however, we can by no means recommend, as it feems moft likely to kill the grain entirely. According to Dr Home, dung is a preventative ofAifeafes difeafes arifing from too great moifture; in confirmation from to°. of which, he relates the following experiment. third with clover, and the fourth with timothy, fome acres of poor ground, which had never got any ma- prevented. horfes, black cattle, and flreep, were turned into it. when the plants were all in a condition for pafturage ; and the timothy was eaten quite bare, before the clover, lucern, or fain-foin, was touched. One valuable property of this grafs is, that its roots are fin ftrong and interwoven with one another, that they render the wetteft and fofteft land, on which a horfe could not find footing, firm enough to bear the heavieft cart. With the view of. improving boggy lands, therefore, fo as to-prevent their being poached with the were fallowed with a defign to be fown with wheat; but the fcheme being altered, fome dung was laid on a fmall part of it, and the whole fowed, after it had got five furrows, with barley. A great quantity of rain fell. The barley on that part which was dung¬ ed was very good; but what was on the reft of the field turned yellow after the rains, and when ripe was not worth the reaping.” ^ • The want of nourifhment in plants may be eafily Difeafe pe- known by their decay ; in which cafe, the only remedy culiart°fef* feet of cattle, Mr Anderfon recommends the cultivation is, to fupply them with food, according to the methods ^ron' of this kind of grafs, from which he has little expecta¬ tion in other refpedts. Sect. VII. Of the Difeafes of Plants. These are divided by Tournefort into the following tlafies. 1.

It is owing to another plant, a fpecies of trefoil, fixing fome violet-coloured dance of juice; 2. From having too little; 3. From its threads, which are its roots, to the roots of the faffron, _ 69 Erte6h of too great an abundance 'Of juices. bad qualities; 4. From its unequal diftribution ; and 5. From external accidents.

Where the plants are of eafy accefs, thefe vermin may be deftroyed by fprinkling the vegetable with lime-water; for quick-lime is a mortal poifon to creatures of this kind, and throws them into the great- eft agonies the moment they are touched with it. On trees, however, where this method cannot fo well be followed, fumigation is the moft proper; and, for this purpofe, nothing is better than the fmoke of vege¬ tables not perfectly dry. In fome cafes the eggs of thofe deftroying creatures may be obferved, and ought without doubt immediately to be taken away. On the fruit trees, as apples, pears, medlars, on fome foreft- trees, the oak and dwarf-maple efpecially, and the white and black thorn in hedges, a kind of little tufts are to be obferved, refembling, at firft fight, withered leaves twifted, by a cobweb, about the uppermoft twigs or branches. Thefe contain a vaft number of little black eggs, that in the fpring produce fwarms of caterpillars which devour every thing. To prevent this, all the twigs on which thefe cobwebs appear fllould be taken off and burnt as foon as poffible. This ought to be done before the end of March, that none of the eggs be allowed fufficient time for hatching. The grubs are a kind of worms which deftroy the corn by feeding upon its roots ; they are transformed every fourth year into the beetles called cock-chaffers, may-bugs. See. they are very deftructive when in their vermicular ftate, and cannot then be deftroyed becaufe they go deep in the ground. When become beetles, they conceal themfelves under the leaves of trees, where they feem afteep till near funfet, when they take their flight. It is only now that they can be deftroyed, and that by a very laborious method; namely, by fpreading pack-(heets below the trees in the day-time when the L T U R E. Part L turnips is, that all the feeds contained in the dung, and Theory, which of courfe are carried on the land with it, vege- v—— tates almoft immediately, are moftly - killed by the fe- verity of the winter, and the few that remain feldom, avoid deftrudlion from the plough-fhare. ^ The following method i of fowing has alfo been re- Various re¬ commended as a preventative of the fly :—“ About medics a- Midfummer, take the firft opportunity when it rains, yj* or there is an apparent certainty of rain approaching, turnil> to fow your turnip feed; if about the full moon, the better. In this cafe, neither harrow, brufh, nor roll, after fowing. The natural heat of the ground at that feafon, and the confequent fermentation occafioned by copious rain, will give an aftonifhingly quick vegeta¬ tion to the feed, which in a few days will be up and out of all danger from the fly. At all events, fow not till it rains ; it is better to wait a month, or even longer, for rain, than to fow (merely for the fake of fowing about the ufual time) when the ground is parched with heat. By the fcorching of the fun, the oil and vegetative quality of the feed are exhaufted; and the few weak plants that come up will be deftroyed by the fly before they can attain ftrength to put forth their rough leaves. The fly infefts the ground abundantly in dry hot wea¬ ther, but do no injury in tain. The falling rain will fufficiently wafh the turnip-feed into the ground with¬ out harrowung it in; which, inftead of merely cover¬ ing, too often buries this fmall feed at fo great a depth, as never afterwards to get above ground.” The following remedies are alfo recommended as having often proved fuccefsful:—A fmall quantity of foot fown over the land at their firft appearance. Bran¬ ches of elder with the leaves bruifed, drawn in a gate over them. Mufk mixed with the feed before it is fown. And fulphur burnt under it, after moiftening beetles are in their torpid ftate, then {baking them off it with water in which tobacco has been fteeped. 77 Turnip-fly. 78 Prevented* by fumiga- wen, &c. and burning them. Some time ago, they made fuch devaftations in the county of Norfolk, that feveral far¬ mers were entirely ruined by them; one gathered 8o buft.els of thefe infects from the trees which grew on his farm. It is faid that, in 1574, there fell fuch a multitude of thefe infefts into the river Severn, that they ftopped and clogged the wheels of the water¬ mills. Turnips, when young, are apt to be totally deftroyed by a multitude of little black flies, from thence called the turnip-fly. As a preveniative of thefe, fome ad- vife the feed, to be mixed with brimftone but this is improper, as brimftone is found to be poifonous to ve¬ getables. The beft method feems to be the fumiga¬ tion of the fields with fmoke of half-dried vegetables. For this purpofe weeds will anfwer as well as any. This fumigation muft no doubt be often- repeated, in order to drive away the innumerable multitudes of thefe But ftiowers on the plants as foon as they appear a- bove ground, are efteemed the beft prefervatives. They enfeeble and kill the fly, and haften the plants into the rough leaf, in which ftate they are out of danger. The fweet fmell ot the turnip has been thought to attraft the fly ; upon which fuppofition, the remedy appeared to confift in overpowering that fmell by one which is ftrong, fetid, and difagreeable. Hence it has. been recommended, that upon an acre of turnips fown in the ufual way, a peck or more of dry foot be thrown after the ground is finiftted, and in as regular a way as he fows the feed. 8a Some time ago an infeft, called the corn-lutterfly. Corn bi committed fuch ravages while in its vermicular ftate, ter%* in France, that upwards of 200 parilhes were ruined by it; and the miniftry offered a reward to the difeo- verer of an effeftual remedy againft this deftroying worm. The cure which was at laft difeovered, was infefts which are capable of deftroying a large field of to heat the corn, in an oven, fo much as not to de- turnip. Some have fuppofod that the fly’ is either engendered in new dung, or enticed by it; and have therefore ad- vifed the manure to be laid on in the autumn prece¬ ding, by which it lofes all its noxious qualities, while its nutritive ones are retained, notwithftanding thefe might be fuppofed liable in fome degree to be exhaled B}r the fun.

It is certain, that though in¬ fefts can bear a great deal of cold, they are eafily de¬ ftroyed by a flight degree of heat; nor is the vegeta¬ tive power of corn eafily deftroyed, even when kept for a long time in a pretty ftrong heat.

I. According to the writer of. the firft letter, this convinced will prevent the curl. All the good potatoes he faw this year, either on frefii ley land or on old-tilled land, were raifed from fets that grew upon frefti ley land laft year; and where I methods of (pfea{'e jg caufed by an iufedt produced by frdft or bad he has feen curled potatoes, he found, upon inquiry. ’ keeping before fetting ; and the neweft kinds, fuch as have been raifed within thefe nine or ten years, are moft apt to curl, beqmfe they will not ftand to be kept in winter and fpring before fetting, as the old kinds will. In autumn 1776, he got up a bed of potatoes to lay by in winter, leaving plenty in the ground as regular as poffible ; and, before the feverity of winter came on, covered part of the bed with ftraw and peafe- haulm, and left the other part of the bed uncovered. the potato-fets grew upon old-tilled and worn-out land laft year. He gives as a general reafon for the difor- der, that the land is oftener cropt than it had ufed to be, much more corn being now raifed than formerly. V. In 1772, this writer planted fome potatoes by accident full nine inches deep : when taken up, many of the plants were rotted, and a few curled. He kept the whole produce for feed, and planted two acres with it in 1773, not quite fix inches deep. The crop v That part of the bed which was covered was quite free amazingly great; and he did not obferve any curled from curled ones ; but the uncovered part produced a great many curled, owing, as the writer fays, to froft and feverity of the weather. plants among them. In 1774, many of thefe were planted in different foils ; yet they were fo infe&ed with the curled difeafe, that not one in twenty efcaped II. This writer had about a quarter of an acre of In 1775, the complaint of this difeafe became general. potatoes, well manured with cow and horfe dung, and took the greateft care in picking the fine fmooth-lkinned potatoes for fets; yet nine out of ten parts were curled. He attributes the caufe of this difeafe to a white grub or infeft, which he found near the root, about half an inch long, with eight or ten legs, its head browm and hard; as upon examining a number of the curled roots, he found them all bitten, chiefly from the furface to In' 1776, it occurred to him that the good crop of 1773 was owing to the accidental deep fetting of 1772 ; and that the reafon why the fame feed became curled in I774> was their being fet fo near the furface in 1773 ; and attributes the difeafe to the pra&ice of ebb-fetting. In 1777, he took fome potatoes from a crop that was curled the year before, and after cutting the fets, left them in a dry robm for a month. Half the root, which of courfe flopped the progrefs of the were planted in ground dug fourteen days before; the fap, and threw the leaf into a curl. The uncurled roots were not bitten. He tried a few experiments as follow:—Firft, he put foot to the infefts in the rows For two days; and after that, he put lime to them for the fame time, but they ftill kept lively ; next he put a little fait, which deftroyed them in a few hours. From which he infers, that if coarfe fait were put into the ground at the time the land is preparing for pota¬ toes, it would effetlually cure this diftemper. III. In this letter, the caufe of the difeafe is attri¬ buted to the method of earthing the Items while in cul¬ tivation ; and the branch, ftriking root into the new other half, having been fteeped in a brine made of whitfter’s alhes for two hours, were alfo planted in the fame land at the fame time. The fteeped ones came up ten days before the others, and hardly any miffed or were curled. The unfteeped ones generally failed, and thofe few that came up were moftly curled. He therefore advifed as a remedy, 1. That the po¬ tatoes intended for next year’s fets be planted nine in¬ ches deep. 2. That they remain in the ground as long as the feafon will permit. 3. That thefe fets be well defended from froft till the beginning of March. 4. That the fets be cut a fortnight before planting. 5. earthed-up foil, it is faid, produces potatoes of fuch a That they be fteeped, as above, two hours in brine or nature as the year following to caufe the difeafe com¬ plained of. To prevent the difeafe, it is recommended to take the fets from thofe potatoes that have not bred any from the branch covered; or otherwife, to dig the part the fets are to be raifed from, IV. According to this writer, the diforder proceeds from potatoes being fet in old-tilled orworn-out ground: ley. 6. That the dung be put over the fets. And 7. That frefli fets be got every year from fandy foils near the coaft, or on the ftiore. P. S. At planting, the hard dry fets ftiould be call afide, for they will probably be curled. Curled pota¬ toes always proceed from fets which do not rot or pu¬ trefy in the ground. VI. This writer had five drills of the old red pota- for though thofe potatoes may look tolerably well, yet toes, and four of the winter whites, growing at the their fets will moft, if not all, produce curled potatoes, fame time in the fame field. The drills were prepared 268 AGRICULTURE. Parti. Theory, exaftly alike. Among the red not one was curled; v""" the winter whites were nearly all curled. He fays he has found by experience, that the red never curl. VII. Two of the writer’s neighbours had their fets out of one heap of potatoes. They both fet with the plough, the one early, and the other late in the fea- fon. Moft of thofe early fet proved curled, and moft of thofe fet late fmooth ; the latter on clay land. A few roods of land were alfo planted with fmall potatoes, which had lain fpread on a chamber floor all the winter and fpring, till the middle of May. They were foft and withered ; they proved fmooth and a good crop. Middle-fized potatoes, withered and foft, which had been kept in a large dry cellar, and the fprouts of which had been broken off three times, pro¬ duced alfo a fmooth good crop. Hence he was led to think a fuperfluity of fap, oc- cafioned by the feed being unripe, might caufe the dif- eafe. To be fatisfied in this, he allied the farmer whe¬ ther he had fet any of the fame potatoes this year, and what was the nature of his land ? He told him “ he had; that they had been fet on his farm fourteen years, without ever curling; that his foil was a poor whitilh fand, of little depth ; that he let thofe he deligned for keeping grow till they were fully ripe.” Hence he concludes, the only fure way to prevent the curl is, to let potatoes intended for feed Hand till they are fully ripe, and to keep them dry all winter. VIII. This writer fet a quantity of the red potatoes^ without having a curled one amongft them. His me¬ thod is, when the fets are cut, to pick out fuch as are icddeft in the inlide. On digging them up at Mi¬ chaelmas, he mixes none of the curled feed among the others. The curled are eafily diltinguilhed, by their ftalks withering two months before the reft- of the crop. The caufe of the curled difeafe he attributes to po¬ tatoes being of late years produced from feed inftead of roots, as formerly. Such will not Hand good more than two or three years, ufe what method you pleafe. Lalt fpring, he fet the old red and white ruffets, and had not a curled potato among!! them. On the lime-ftone. land about Denbigh, in North Wales, they have no curled potatoes. If this be ow¬ ing to the nature of that land, perhaps lime might pre¬ vent the difeafe., IX. , According to this writer, all- forts of grain wear out»and turn wild if fown too long -on the fame land; the fame will hold good in all forts of pulfe, peafe, beans, and (as he conceives) potatoes. It ge¬ nerally happens, that thofe who have moft curled po¬ tatoes plant very, fmall fets. Eleven years ago he bought a parcel of frefh fets, of the golden-dun kind, and has ufed them without change to the prefent year, without- arty being curled. This he principally attributes to his having always planted good large fets. About four years fince, he thought of changing hk fets, as his potatoes were too fmooth, too round, and much diminifhed in fi/.e. But the curl at that time beginning to. be very, alarming, he continued his fets till part of his crop miffing laft year, he was obliged to buy new fets this fpring, which, being fmall,. were curled like other peoples.,,, He allows, that the curl has frequently happened to Theory, perfons who have ufed large potatoes for fets ; for, as v—' all roots are not equally affedted, fome curled ones may be mixed with the reft. To prevent the evil, cut your fets from clear and middle-fized potatoes, gathered from places as clear of the curl as poffible ; preferve them as ufual till fpring. If any are harder, or grafli more in cutting than ufual, . caft them afide. He would alfo recommend the railing a frefh fort from the crab produced bn the forts leaft affefted, which in Lancafhire are the long-duns.. X. Set potatoes with the fprits-broke off, .and they will (fays the writer of this letter) be curled ones; if fet with the fprits on, they will not be curled. Again, take a potato which is fprit, and cut a fet off With two . fights : break one fprit off, and let the other ftay on, and fet it; the former will be curled, and the latter will mot. When you have holed your potatoes, take them out before they are fprit, and lay them dry until you have fet pr fown them, and you wilh have no curled po¬ tatoes. XL This writer was at the expence of'procuring fets at fifty miles diftance, and where this difeafe was not known.- The firft year’s trial was fuccefsful; the year following he procured fets from the fame place,, but one-fifth of his crop was infe&ed. By way of ex¬ periment; he planted fets from roots which had been infedfted the year before, and fome of thefe produced healthy plants, free from all infection. As. every effect muft have a caufe, he fuppofed it might be fome infe£t, which, living on the leaves, gave them that curled and lickly appearance, as is the cafe in the leaves of many (hrubs and trees. But whether the infeft is lodged in the old fets, and to be deftroyed at the time of planting, or, proceeding from fome ex¬ ternal caufe, can only be deftroyed afterwards, he is not yet certain, although he has made the following- experiments. On a piece of ground that had not been dug for 20 , years, he planted four rows of fets, which he knew to he perfectly clear; the drills were two feet diftant, the fets one foot diftant in each drill. He then planted ' on the fame ground four rows .with fets from curled ; , potatoes, at equal diftances; in each row were about. 20 fets. Lot i ft, the curled ft ate.. N° I. Without manure, I N° 3.

This writer advifes fuch fets to be planted as grow in mofs-land ; and, he fays, there will not be a fingle curled one the firft year.. This is affirmed by the inhabitants of two townihips, where they grow a- mazing quantities.—A medical gentleman fowed fail year two buihels of fets from one of the above places, and had not one curled ; but on fowing them again this year, lie had a few. Notwithftanding there feems to be a diverfity of opinions in the above writers, occafioned by the diffe¬ rent appearances of their crops, and the feemingly contrary effefts of the means ufed to prevent or cure the difeafe, we conceive that the following general propofitions may be fairly draxvn from the whole, i. That fome kinds of potatoes are {c&tcris paribus') much more liable to be affe&ed by the difeafe than the reft; and that the old-red, the golden-dun, and the long-dun, are the moft free from it.—-2. That the difeafe is occafioned by one or more of the following caufes, either finglyor combined : I ft, By froft, either before or after the fets are planted : 2d, From planting fets out of large unripe potatoes: 3d, From planting too near the furface, and in old wdrn-out ground: 4th, From the firft ftioots of the fets being broken off before plant¬ ing; by which means there is an incapacity in the plan- ta feminalis to fend forth others fufficiently vigorous to expand fo fully as they ought.—3.

PRACTICE of AGRICULTURE. Sect. I. Injlruments of Hv/bandry- nn HE inftruments employed in agriculture are vari- JL ous; as the plough, the harrow, the roller, &c. which are again greatly diverfified by various conftruc- tions adapted to particular ufes. 1. Of Ploughs. 5cots plough. 84 Defcription of the Scots plough. Plate IV. % I- The plough conftrufted in the following manner is Hill the moft common and the moft generally underftood in Scotland ; and, if properly made, is the beft for an- fwering all purpofes, when only one is ufed ; though others are, perhaps, more proper on fome particular oe- cafions. The parts of which this plough is compofed, are, the head, the beam, the fneath, the wreft, the mould-board, the two handles, the two rungs, the fock, and the coul¬ ter; the two laft are made of iron, and all the reft ofwood, The Head, is defigned for opening the ground be¬ low. The length of the head from A to B is about 20 inches, and the breadth from A to D about five inches; C is the point upon which the fock is driven, and the length from B to C is about fix inches; a is the mor- toife into which the larger handle is fixed, and l is the mortoife into which the fheath is fixed. The head is that part of the plough which goes in the ground; therefore the ihorter and narrower it is, the friction will be the lefs, and the plough more eafily drawn ; but the longer the head is, the plough goes more fteadily, and is not fo eafily put out of its direc¬ tion by any obftru&ions that occur. Twenty inches is confidered as a mean length; and five inches as the moft convenient breadth. The Sheath, E, is driven into the mortoife l, and Fig. 3, thus fixed to the head A B. It is not perpendicular to the head, but placed obliquely, fo as to make the angle formed by the lines A B and E B about 60 degrees. The (heath is about 13 inches long, befides what is dri¬ ven into the mortoife b (fig. 1.); about three inches broad, and one inch thick. The (heath is fixed to the mould-board, as in fig. 11. E, in the fame manher as the wreft is fixed to the head •in fig. 7- The Mould-board, is defigned to turn, over thfFig. 3. earth of the furrow made by the plough ; and it is ob¬ vious, that, according to the polition of the (heath, the mould-board will turn over the earth of the furrow more or lefs fuddenly. Befides, when it forms a lefs angle with the head than 60 degrees, the plough is in great danger of being choked, as the farmers term it. The V “iPart IT. A G R I C U MPraAice. ^ The Larger Handle, F A, is fixed to the head, by ll' " v driving it into the mortoife « (fig. i.). It is placed in the n fame plane with the head ; and its length from. A F is about five feet four inches, and its diameter at the place where it is fixed to the beam is about two inches and an half, and tapers a little to the top F. About ten inches from A, there is a curve in the handle,, which, when F is raifed to its proper height, makes the lower part of it nearly parallel to the (heath E B. This curve is de- I iigned to ftrengthen the handle. The proper pofition of the handle is, when the top F is about three feet two inches higher than the bottom of the head A B; The longer the handles, the plough is the more eafi- ly managed, becaufe the levers are more dirtant from the centre of motion. The higher the top of the handles, the plough is more eafily raifed out of the ground, pro¬ vided they be no higher than the lower part of a man’s breaft. ?3g-4- The Beam, is fixed to the larger handle and the fheath, all of which are -placed in the fame plane with the head. The length of it, from H to I, js about fix feet; its diameter is about four inches. When the plough is in the ground, the beam (hould be juft high enough not to be incommoded by anything on the fur- ' face. The pofition of the beam depends on the number of cattle in the plough. When two horfes are yoked, the beam fhould be placed in fuch a manner as to make the perpendicular diftance betwixt the bolt-hole of the beam and the plane of the head about ti inches.; when four horfes are yoked, two a-breaft, this diftance {hould only be about 18 inches. I'Fig.J* The Sock, BP, is fixed to the end of the head, and is about two feet Idng. In. fitting the fock to the head, the point ought to be turned a little to the land or left fide; becaufe otherwife it is apt to come out of the land altogether. When turned1 to the left, it likewife takes off more land ; when turned upwards, the plough: goes fhallow; and when downwards, it goes deeper. |Fig.-6. The Coulter,, is fixed to the beam, and is about two feet ten inches-long, two inches and a half broad, (harp at the point and before, and thick on the back, like a knife. It is fixed and directed by wedges, fo as to make the point of it equal to, or rather a little be¬ fore the point of the fock,.and upon aline with the left fide of the head. This oblique pofition enables it to throw roots, &c. out of the land, which requires lefs force than cutting or puffing them forward. : %•’ 7- The Wrest, BD, is fixed to the head, and is about 2(5 inches long, two broad, and one thick. It is fixed to the head at B, in fuch a manner as to make the angle contained between the lines AB and BD about 25 degrees^ The wreft is feldom or never placed in the fame plane with the head, but gradually raifed from the place where it is fixed to it; that is, from B to K, It as in fig. 8. The pofition of the wreft determines the nature of the furrow. When the wreft is wide and low , fet, the furrow is wide; and when it is najTow and high fet, the furrow, is narrow. Fig. 9. reprefents the two Handles, fixed together by the two rungs. The larger handle has already been deferibed; the leffer one is a few inches fforter, and does not require to be quite fo ftrong. The diftance of the handles at the little rung depends on the pofition of the wreft. Their diftance at M and P is about two 3 . L T U R E. 271 feet fix inches. The leffer handle is fixed to the mould Practice, board at M, fig. 10. and to the wreft K B, at L. 1—~-v—j Fig. 11. reprefents the plough complete, by joining together figures 6. and 10. in the ffeath E B. The wreft B K is fuppofed to make an angle with the head A B as in fig. 7. and the handles joined together as in %• 9* . \ . After having given fuch a particular defeription of all the parts and proportions of the Scots plough, it will eafily appear how it feparates, raifes, and turns over the earth of the furrow. If it had no coulter, the earth would open above the middle of the fock, and in a line before the ffeath; but as the coulter opens the earth in a line with the left fide of the head, if the foil has anycohefion, the earth of the furrow will bewholly rai- fed from the left fide, and, as the fock moves forward, will be thrown on the right fide of the ffeath, and bv the calling out of the mould-board, or the railing of the wreft, will be turned oyer. The Bridle, or Muzzle, is another article belong- Fig. 12. ing to the plough. It is fixed to the end of the beam, and the cattle are yoked by it. The muzzle commonly ufed is a curved piece of iron, fixed to the beam by a bolt through it. ABC is the muzzle, A C the bolt by which it is fixed to the beam; D is the fwingle-tree or crofs-tree, to which the.traces are fixed ; and B is a hook, ox cleeky as it is commonly called, which joins , the muzzle and fwingle-tree. Some ufe another kind of muzzle, A B C D. It is Fig. 13. fixed to the beam by two bolts, and has notches by ° which the cleek of the fwingle-tree may be fixed ei¬ ther to the right or the left, of the beam. There are alfo different holes for the hind-bolt to pafs thro’, by which, the draught may be fixed either above or below the beam. AD is the fore-bolt upon which the muzzle turns ; on B C are four notches, betwixt any two of which the cleek of the fwingle-tree may be fixed. When the cleek is fixed at B, the plough is turned to- wards the firm land, and takes off a broader furrow ; and when fixed at C, it is turned towards the plough¬ ed land, and takes of a narrower furrow. E and F are the holes on each fide thro’ which the hindmeft bolt, panes. When the bolt is put thro’the higheft two, thefe holes being thereby brought to the middle of the beam, , the fore-part of the muzzle is raifed above the beam, and the plough is made to go deeper; and when put through the loweft two, the fore-part of the muzzle is - funk below the beam, and the plough is made to go {hallOwer. This muzzle may be fo conftrudleu as to have the fame play with the common one. A is thepig. zA end of the beam ; B a plate of iron funk into it, and, with a fimilar one in the other fide, is rivetted into it by bolts; C is the muzzle fixed to thefe plates of iron * by the bolt D, which bolt may be put through any of the holes E E.

Thefe teeth muft be made of fled, very fine, and fo long as to reach down to the plank on which the dire£lors are fixed, that is Practice, to fay, fix inches long (the dire&ers r.re alfo to lie v made fix inches broad above the plank). The rake- head fhould alfo fall a little before the crank is at its extremity, which will caufe the rake to pufh forward to let the teeth come into the roots. The rake-teeth muft drop in the fame plane with the roller and wlvels, or on the furface of the earth. No more fpace fhould be given from the roller C to the long teeth at G G than that the rake may juft mifs the fpikes of the rol¬ ler C and fall on the places before mentioned. As the ftrft roller B was intended to cleanfe the fecond C more than for any other- ufe, it may be omitted when the machine is made in large, as Mr Ogden has lately found that the long teeth at G G anfwer the end alone, and this renders the machine about a fixth part fhorter; Now, to fuit any fort of earth, there fhould be to each machine three planks, with directors at different fpaces, to ufe occafionally; in the firft, the fpaces between the directors fhould be eight inches wide, in the fecond fix, and the third four.. This will anfwer the fame end'as having fo many machines. As there may be fome objections- to the rake not leaving the roots when it has brought them up, Mr Ogden has feveral methods of cleanfing it; but as he would make it as fimple as pofiible, he choofes to let it be without them at prefent p but. fuppofe it fhould bring fome roots back , again with it, it will probably lofe them before it gets back to the extremity ; whence they will lie light, and be of but little detriment to. the others coming up. Mr Ogden would have the firft machine made four feet fix inches wide, the teeth . divided into equal fpaces, the outfides into half fpaces,-. 7. The new-invented Patent Univerfal Sowing , Machire. This machine, whether made to be worked by handj Univeffal ' drawn by a horfe, or fixed to a plough, and ufed with lowing it, is extremely fimple in the. conftruClion,.and notra,aciline,r liable to be put out of order; as there is but one movement to diredf the whole, nor does it require any fkill in working. It will fow wheat, barley, oats, rye, clover, cole-feed, hemp, flax, canary, rape, turnip, be- fides a great, variety of other kinds of grain and feeds broad-caft, with an accuracy hitherto unknown. It is equally ufeful in the new hufhandry, particularly when fixed to a plough ; it will then drill a more exten- five variety of grain, pulfe, and feed (through every gradation, with regard to quantity), and deliver each kind with greater regularity than any. drill-plough whatever. When ufed in this manner, it will likewile be found of the utmoft fervice to farmers who are par¬ tial to the old hufbandry, as, among many other very valuable and peculiar properties, it will not only fow in the broad-cafl way with a moft fingular exaftnefs, but fave the expence of a. feedfman; the feed being fown (either over or-under furrow at. pleafure), and the land ploughed, at the fame operation. Perhaps a fair and deeifive experiment for, afcertain- ing the fuperior advantage of broad-cafting or drilling any particular crop, was never before fo practicable; as the feed may now be put in with the utmoft degree of regularity, in both methods of culture,. by the fame; machine; AGRICULTURE. Part II machine; confequeritly, the feed will be fown in both cafes with equal accuracy,. without which it is impof- fible to make a juft decifion. The excellence of this machine confifts in fpreading ■ any given quantity of feed over any given number of acres, with a mathematical exa&nefs, which cannot be done by hand ; by which a great faving may be made in feeding the ground, as well as benefiting the ex¬ pected crop. There has always been a difficulty in fowing turnip feed with any degree of exactnefs, both from the mi- nutenefs of the feed, and the fmallnefs of the quantity required to be .fown on an acre. Here the machine has a manifeft advantage, as it may be fet to fow the leaft quantity ever required on an acre; and with an accuracy the beft feedfman can never attain to. It will alfo fow clover, cole, flax, and every other kind of final! feed, with the utmoft degree of regularity. It will likewife broad-caft beans, peafe, and tares, or drill them with the greateft exadftnefs, particularly when conftrufted to be ufed with a plough. Another advantage attending the ufe of this machine is, that the wind can have no effe& on the falling of the feed. Of the Machine when made to he ufed without a Plough, and to be drawn by a Horje.—It may in this cafe be made of different lengths at the defire of the purchafer. The upper part AAA A, contains the hoppers from which the grain or feed defcends into the fpouts. The feveral fpouts all reft upon a bar, which hangs and plays freely by two diagonal fupport- ers BB; a trigger fixed to this bar bears a catch wheel: this being fixed on the axle, occafions a regular and continual motion, or jogging of the fpouts, quicker or flower in proportion to the pace the perfon fowing with it drives; and of courfe, if he quickens his pace, the bar will receive a greater number of ftrokes from the catch wheel, and the grain or feed will feed the fafter. If he drives flower, by receiving fewer -ftrokes, the contrary muft take place. In going along the fide of a hill, the ftrength of the ftroke is corre&ed by a fpring which afts with more or lefs power, in pro¬ portion as the machine is more or lefs from a horizon¬ tal pofition, and counteracts the difference of gravity in the bar, fo that it preffes, in all fituations, with a pro¬ per force againft the catch wheel. This fpring is un- neceffary if the land be pretty level. At the bottom of the machine is placed an apron or fhelf in a Hoping pofition, and the corn or feed, by falling thereon from the fpouts above, is fcattered about in eveiy direction under the machine, and covers the ground in a moft regular and uniform manner. To fow the -corn or feed in drills, there are moveable fpouts, (fee fig. 10.) which are fixed on, or taken off at pleafure, to direft the feed from the upper fpout to the bottom of the furrow. The machine is regulated for fowing any particular .quantity of feed on an acre by a brafs Aider, A, fig. 7. fixed by fcrews againft a brafs bridge on each of the fpouts. The machine is prevented from feeding while turning at the ends, by only removing the lever, E, fig. 2. out of the channel G, to another at H, on the right hand of it, which carries back the bar from the catch-wheel, and occafions the motion of the fpouts to eeafe, and at the fame tirfie brings them upon a level N0;. by the aftion of the diagonal fupporters; fo that no corn or feed can fall from them. The machine in this form is particularly ufeful for broad-cafting clover upon barley or wheat; or for fow¬ ing any other kind of feed, where it is neceflary that the land fhould firft be harrowed exceedingly fine and even. Manner of ufing the Machine, when drawn by a Horfe.—Place the machine about two feet from the ends of the furrows where you intend it ftiall begin to fow. Fill the hoppers with feed, and drive it forwards with the outfide wheel in the firft furrow. When you are at the end of the length, at the oppofite fide of the field, lift the lever E, fig. 2, into the channel H, and the machine will inftantly ftop fowing. Drive it on about two feet, and then turn. Fill the hoppers again if neceflary; then remove the lever back again into the channel G, and in returning, let the outfide wheel of the machine go one furrow within the track which was made by it, in pafling from the oppofite end; as for example, if the wheel pafled down thfc eighth fur¬ row from the outfide of the field, let it return in the feventh; and in every following length let the outfide wheel always run one furrow within the traft made by the fame wheel: becaufe the breadth fown is about nine inches lefs than the diftance between the wheels. Let the machine be kept in a perpendicular fitua- tion. If the farmer wifhes to fow more or lefs feed on any one part of the field than the other, it is only raifing the handles a little higher, or finking them a little lower than ufual, and it will occafion a fufficient alteration; and flrould the laft turn be lefs in breadth than the machine, thofe fpouts which are not wanted may be taken up from the bar, and prevented from feeding, by turning the knob above them. Alfo, when the land required to be fown has what is called a -cent, that is, when the fides of the field run in an oblique line to the furrows, w hich by this means are unequal in length; the fpouts muft be taken up or let down in fucceffion by turning the knobs; as that part of the machine, where they are placed, arrives* at the ends of the furrowrs. This is done while the ma¬ chine is going forwards. If the land be tolerably level, the machine may be fixed by the fcrew in the front, and the machine may then be ufed by any common harrow boy. Method of regulating the Machine.—In each fpout is fixed a bridge, (fee fig. 7.) with an aperture in it, B, for the grain or feed to pafs through. This aperture is enlarged or contracted by a Aider, A, which pafies over it; and when properly fixed for the quantity of feed defigned to be fown on an acre, is faftened by means of two ftrong fcrews firmly againft the bridge. This is made ufe of in fowing all kinds of feed, where it is required to fow from one buffiel upwards on an acre. To fow one, two, three gallons, or any of the inter¬ mediate quantities, as of clover, cole-feed, &c. the brafs plate, fig. 6, is placed between the bridge and the Aider, with the largeft aperture B downwards, which aperture is enlarged or contracted by the Aider as be¬ fore. To fow turnips, the fame plate is placed between the bridge and the Aider, with its fmalleft aperture A downwards, and the hollow part about the fame aper¬ ture inwards. Fig. 8. is a view of the regulator, by which the 2 apertures Praftice. A<®IGITLTflTRE. Flnte VI. | Part II.

Fig. 11. reprefents the machine fixed to a double¬ furrow creafing plough, and prepared for drilling. As this plough may not be generally known, it will not be improper to obferve, that it is chiefly ufed for creafing the land with furrows (after it has been once ploughed and harrowed); which method is neceifary when the feed is to be fown broad-caft upon land that has been a c lover-lay, See. b'ecaufe, if the feed be thrown upon the rough furrows, a confiderable part of it will fall be¬ tween them, and be unavoidably loft, by laying too deep buried in the earth. This mode anfwers ex¬ tremely well, and partakes of both methods of culture; the feed, though fown broad-caft, falling chiefly into the furrows. The machine is very ufeful for fowing in this man¬ ner; as the feed is broad-caft, with an inconceivable regularity, at the time the land is creafed. The ad¬ vantages it likewife pofiefies for drilling all forts of grain or feed with this plough, are too evident to need mentioning. The machine, when conftru&ed to be ufed with a double-furrow plough, is made with two upper and two long fpouts for drilling, two aprons for broad- cafting, and with a double hopper; but in other re- fpefts the fame as when intended for a Angle furrow plough: it is ufed in all cafes with the greateft eafe imaginable. The interval between the points of the two /hares of a creafing plough is ufually ten inches; the beam about nine feet long; and the whole made of a light con- ftm&ion. sJPlateVH A more particular explanation of the figures.—Fig. I.

Obstructions to Cropping. 106 In preparing land for cropping, the firft thing that Ob/lruc- occurs, is to coniider the obftruflions to regular plough-tlons> 'V'!S ing. The moft formidable of thefe, are Jlones lying a- stones* bove or below the furface, which are an impediment to a plough, as rocks are to a fliip. Stones above the furface may be avoided by the ploughman, though not without lofs of ground ; but ftones below the furface are commonly not difeovered till the plough be flrat- tered to pieces, and perhaps a day’s work loft. The clearing land of ftones is therefore neceffary to prevent mifehief. And to encourage the 'operation, it is at¬ tended with much actual profit. In the firft place, the ftones are ufeful for fences: when large they muft be blown, and commonly fall into parts proper for build¬ ing. And as the blowing, when gunpowder is furni/h- ed, does not exceed a halfpenny for each inch that is bored, thefe ftones come generally cheaper than to dig as many out of the quarry. In the next place, as the foil round a large ftone is commonly the beft in the field, it is purchafed at a low rate by taking out the ftone. Nor is this a trifle ; for not only is the ground loft that is occupied by a large ftone, but alfo a con¬ fiderable fpace round it, to which the plough has not accefsjyjthout danger. A third advantage is greater than all the reft; which is, that the ploughing can be carried on with much expedition, when there is no ap- prehenfion of ftones: in ftony land, the plough muft proceed fo flow, as not to perform half of its work. To clear land of ftones, is in many inftances an un¬ dertaking Part II. AGRICULTURE. 283 Pra&ice. dertaking too expenfive for a tenant who has not a *•—““v very long leafe. As it is profitable both to him and to his landlord, it appears reafonable that the work fhould be divided, where the leafe exceeds not nineteen years. It falls naturally upon the landlord to be at the expence of blowing the ftones, and upon the tenant to carry I ioS them off the field, Wetnefs. Another obitruftion is wet ground. Water may improve gravelly or fandy foils ; but it fours (a) a clay foil, and converts low ground into a morafs, unfit for any purppfe that can interell the hufbandman. A great deal has been written upon different me¬ thods of draining land, mollly fo expenfive as to be fcarce fit for the landlord, not to mention the tenant. One way of draining without expence when land is to be inclofed with hedge and ditch, is to diredl the ditches fo as to carry off the water. But this method is not always practicable, even where the divifions lie con¬ venient for it. If the run of water be confiderable, it will deftroy the ditches, and lay open the fences, efpe- cially where the foil is loofe or fandy. If ditches will not anfwer, hollow drains are fome- times made, and fometimes open drains, which muff be made fo deep as to command the water. The former is filled up with loofe ftones, with brufii-wood, or with any ether porous matter that permits the water to pafs. The latter is left open, and not filled up. To make the former effedlual, the ground mull have fuch a flope as to give the water a brifle courfe. To execute them in level ground is a grofs error: the paffages are foon Hopped up with fand and fediment, and the work is rendered ufelefs. This inconvenience takes not place in open drains ; but they are fubject to other inconve¬ niences : They are always filling up, to make a yearly reparation neceffary ; and they obftruCt both plough¬ ing and pa fturing. The following is the bell in all view's. It is an open drain made with the plough, cleaving the fpace in¬ tended for the drain over and over, till the furrow be made of a fufficient depth for carrying off the water. The flope on either fide may, by repeated ploughings, be made fo gentle as to give no obltruction either to- the plough or to the harrow. There is no occafion for a fpade, unlefs to fmooth the fides of the drain, and to remove accidental obftrudlions in the bottom. The advantages of this drain are manifold. It is executed at much lefs expence than either of the former; and it is perpetual, as it can never be obftrudled. In level ground, it is true, grafs may grow at the bottom of the drain ; but to clear off the grafs once in four or five years, will reftore it to its original perfection. A hol¬ low drain may be proper between the fpring-head and the main drain, where the diftance is not great; but in every other cafe the drain recommended is the belt. Where a level field is infefted with water from higher ground, the water ought to be intercepted by a ditch carried along the foot of the high ground, and terminating in fome capital drain. The only way to clear a field of water that is hollow in the middle, is to carry it off by fome drain ftill low- Pradice. er. This is commonly the cafe of a morafs fed with w—^ water from higher ground, and kept on the furface by a clay bottom. A clay foil of any thicknefs is never peftered with fprings; but it is peftered with rain, which fettles on the furface as in a cup. The only remedy is high nar¬ row' ridges, w'ell rounded. And to clear the furrows, the furrow of the foot-ridge ought * to be confiderably low'er, in order to carry off the water cleverly. It can¬ not be made too low, as nothing hurts clay foil more than the ftagnation of water on it; w'itnefs the hollows at the end of crooked ridges, which are abfolutely bar¬ ren. Some gravelly foils have a clay bottom; which is a fubftantial benefit to a field when in grafs, as it re¬ tains moifture. But when in tillage, ridges are necef¬ fary to prevent rain from fettling at the bottom ; and this is the only cafe where a gravelly foil ought to be ridged. Clay foils that have little or no level, have fometimes a gravelly bottom. For difeharging the water, the bell method is, at the end of every ridge to pierce down to the gravel, which will abforb the water. But if the furrow of the foot-ridge be low enough to receive all the water, it will be more expeditious to make a few holes in that furrow. In fome cafes, a field may be drained, by filling up the hollows with earth taken from higher ground. But as this method is expenfive, it will only be taken where no other method anfwers. Where a field happens to be partly wet, partly dry, there ought to be a feparation by a middle ridge, if it can be done conveniently ; and the dry part may be ploughed while the other is drying. The low part of Berwickftiireisgenerallya brick clay, extremely wet and poachy during winter. This in a good meafure may be prevented by proper inclofing, as there is not a field but can be drained into lower ground all the way down to the river Tweed. But as this would ieffen the quantity of rain in a dry cli¬ mate, fuch as is all the eaft fide of Britain, it may ad¬ mit of fome doubt whether the remedy would not be as bad as the difeafe. {See the article Draining.) 2. Bringing into culture, Land from the STATE of NATURE. To improve a moor, let it be opened in winter when Moorifii it is wet; which has one convenience, that the plough ground, cannot be employed at any other work. In fpring, after froft is over, a flight harrowing will fill up the feams with mould, to keep out the air, and rot the fod.. In that Hate let it lie the following fummer and winter, which will rot the fod more than if laid open to the air by ploughing. Next April, let it be crofs-ploughed, braked, and harrowed, till it be fufficiently pulverized. Let the manure laid upon it, whether lime or dung, be intimately mixed with the foil by repeated harrow- ings. This will make a fine bed for turnip-feed if fown broad-caft. But if drills be intended, the method mull N n 2 be (a) By this expreffion it is not meant that the ground really becomes acid, but only that it becomes unfit for the purpofes of iiegetation. The natural products of fuch a foil are rulhes and four grafs: which lall ap¬ pears in the furrows, but feldom in the crown of the ridge ; is dry and taftelefs like a chip of wood ; and feels rough when ftroked backwards. 284 A G R I C U Practice, be followed that is direcled afterward in treating more direflily of the culture of turnip. A fuceefsful turnip-crop, fed on the ground with fheep, is a fine preparation for laying down a field with grafs-feeds. It is'an improvement upon this method, to take two or three fucceffive crops of turnip, which will require no dung for the fecond and following crops, no This will thicken the foil, and enrich it greatly. Swampy The beft way of improving fwampy ground after groimd. dra;ning) is paring and burning. But where the ground is dry, and the foil fo thin as that the furface cannot be pared, the beft way 6f bringing it into tilth from the ftate of nature, as mentioned above, is to plough it with a feathered fock, laying the graffy furface un¬ der. After the new furface is mellowed with froft, fill up all the feams by harrowing crofs the field, which by excluding the air will effectually rot the fod. In this ftate let it lie fummer and winter. In the begin- ing of May after, a crofs-ploughing will reduce all to fmall fquare pieces, which muft be pulverized with the brake, and make it ready for a May or June crop. .If thefe fquare pieces be allowed to lie long in the fap without breaking, they will become tough and not be eafily reduced. 3. Forming Ridges. ©f ridges. The firft thing that occurs on this head, is to con- fider what grounds ought to be formed into ridges, and what ought to be tilled with a flat furface. Dry foils, which fuffer by lack of moifture, ought to be tilled flat, which tends to retain moifture. And the method for fuch tilling, is to go round and round from the cir¬ cumference to the centre, or from the centre to the cir¬ cumference. This method is advantageous in point of expedition, as the whole is finilhed without once turn¬ ing the plough. At the fame time, every inch of the foil is moved, inftead of leaving either the crown or the furrow unmoved, as is commonly done in tilling ridges. Clay foil, which fuffers by water Handing on it, ought to be laid as dry as poffible by proper ridges. A loamy foil is the middle between the two mentioned. It ought to be tilled flat in a dry country, efpecially if it incline to the foil firft mentioned. In a moift country, it ought to be formed into ridges, high or low according to the degree of moifture and tendency to clay. In grounds that require ridging, an error prevails, that ridges cannot be raifed too high. High ridges labour under feveral difadvantages. The foil is heap¬ ed upon the crown, leaving the furrows bare : the •crown is too dry, and the furrows too wet: the crop, which is always beft on the crown, is more readily flra- ken with the wind, than where the whole crop is of an equal height: the half of the ridge is always covered from the fun, a difadvantage which is far from being ■flight in a cold climate. High ridges labour under another difadvantage in ground that has no more level than barely fufficient to carry off water: they fink the furrows below the level of the, ground; and confe- quently retain water at the end of every ridge. The furrows ought never to be funk below tbe level of the ground. Water will more effe&ually be carried off by leffening the ridges both in height and breadth : a l. T U R K. Part II; i narrow ridge, the crown of which is but 18 inches Prathke. 'j higher than the furrow, has a greater flape than a very '—1 broad ridge where the difference is three or four feet. Next, of forming ridges where the ground hangs confiderably. Ridges may be too fteep as well as too horizontal; and if to the ridges be given all the fteep- nefs of a field, a heavy fhower may do irreparable mif- chief. To prevent fuch mifehief, the ridges ought to be fo directed crofs the fi-dd, as to have a gentle flope for carrying off water flowly, and no more. In that refpedl, a hanging field has greatly the advantage of one that is nearly horizontal; becaufe in the latter, there is no opportunity of a choice in forming the ridges. A hill is of all the beft adapted for dire&ing the ridges properly. If the foil be gravelly, it may be ploughed round and round, beginning at the bottom and afeending gradually to the top in a fpiral line. This method of ploughing a hill, requires no more force than ploughing on a level; and at the fame time removes the great inconvenience of a gravelly hill, that rains go off too quickly; for the rain is retained in every furrow. If the foil be fuch as to require ridges, they may be direfted to any flope that is proper. In order to form a field into ridges, that has not been formerly cultivated, the rules mentioned are eafily put in execution. But what if ridges be already formed, that are either crooked or too high ? After feeing the advantage of forming a field into ridges, people were naturally led into an error, that the higher the better. But what could tempt them to make their ridges crook¬ ed ? Certainly this method did not originate from de- fign ; but from the lazinefs of the driver fuffering the cattle to turn too haftily, inftead of making them finifli the ridge without turning. There is more than one difadvantage in this flovenly practice. Firft, the wa¬ ter is kept in by the curve at the end of every ridge, and fours the ground. Next, as a plough has the leaft fridlion polfible in a ftraight line, the friftion muft be increafed in a curve, the back part of the mouldboard preffing hard on the one hand, and the coulter preffing bard - on the other. In the third place, the plough moving in a ftraight line, has the greateft command in laying the earth over. But where the ftraight line of the plough is applied to the curvature of a ridge in order to heighten it by gathering, the earth moved by the plough is continually falling back, in fpite of the moft Ikilful ploughman. The inconveniences of ridges high and crooked are fo many, that one would- be tempted to apply a remedy at any rifle. And yet, if the foil be clay, it would not be advifable for a tenant to apply the remedy upon a leafe flrorter than two nineteen years. In a dry gravelly foil, the work is not difficult nor hazardous. When the ridges are cleaved two or three years fnccef* lively in tHe courfe of cropping, the operation ought to be concluded in one fummer. The earth, by reite¬ rated ploughings, fliould be accumulated upon the fur¬ rows, fo as to raife them higher than the crowns : they cannot be raifed too high, for the accumulated eartb will fubfide by its own weight. Crofs-ploughing once or twice, will reduce the ground to a flat furface, and give opportunity to form ridges-at will. The fame method brings down ridges in clay foil: only let care be taken to carry on the work with expedition; be¬ caufe Part. IT.

But, if he fuddenly levels his high ridges by any of thefe mechanical contrivan¬ ces, he of neceffity buries all the good mould that was on the top of the ridges in the old furrows ; by which he greatly impoveriffies one part of his field, while he too much enriches another ; infomuch that it is a mat¬ ter of great difficulty, for many years thereafter, to get the field brought to an equal degree of fertility in dif* ferent places; which makes it impoffible for the far¬ mer to get an equal crop over the whole of his field by any management whatever : and he has the mortifica¬ tion frequently, by- this means, to fee the one half of his crop rotted by an over-luxuriance, while other parts of it are weak and fickly, or one part ripe and ready for reaping, while the other is not properly filled ; fo that it were, on many occafions, better for him to have ‘ But, where a man is fecure of pofleffing his ground for any confiderable length of time, the advantages that he will reap from having level and well laid-out fields, are fo confiderable as to be worth purchafing, if it fliould even be at a confiderable expence. But the lofs that is fultained at the beginning, by this mecha¬ nical mode of levelling ridges, if they are of confider¬ able height, is fo very great, that it is perhaps doubt¬ ful if any future advantages can ever fully compenfate it. I would therefore advife, that all this levelling apparatus fhould be laid afide ; and the following more efficacious practice be fubftituted in its ftead : A prac¬ tice that I have long followed with fuccefs, and can fafely recommend as the very belt that has yet come to my knowledge. iij “ If the ridges have been raifed to a very great nie‘ height, as a preparation for the enfuing operations,j'y'nLj, they may be firlt cloven, or fealed out, as it is called in ‘ _ different places ; that is, ploughed fo as to lay the earth on each ridge from the middle towards the furrows. But, if they are only of a moderate degree of height, this operation may be omitted. When you mean to proceed to level the ground, let a number of men be his whole field reduced at once to the fame degree of collefted, with fpades, more or fewer as the nature of poornefs as the pooreft of it, than have it in this ftate.

And when he has finifhed that part of the furrow allotted to him that the plough has made in going, let him then go and finifh in the fame manner his own portion of the furrow that the plough makes in returning. In this manner, each man performs his own talk through the whole field, gradually raifing the old furrows as the old heights are deprelfed. And, if an attentive over- feer is at hand, to fee that the whole is equally well done, and that each furrow is railed to a greater height than the middle of the old ridges, fo as to allow for the fubfiding of that loofe earth, the operation will be en¬ tirely finilhed at once, and never again need to be re¬ peated* “ In performing this operation, it will always be proper to make the ridges, formed for the purpofe of levelling, which go acrofs the old ridges, as broad as poffible ; becaufe the deep trench that is thus made in each of the furrows are an impediment in the future operations, as well as the height that is accumulated in the middle of each of thefe ridges; fo that the fewer there are of thefe, the better it is. The farmer, there¬ fore, will do well to advert to this in time, and begin by forming a ridge by always turning the plough to the right hand, till it becomes of fuch a breadth as makes it very inconvenient to turn longer in that man- per; and then, at the diftance of twice the breadth of expences of levelling by the plough and by the fpade, Practice. 1 in which he finds the latter by far the cheapeil me- v—^ thod. xi6 I Let it be a rule, to direft the ridges north and Proper di- | fouth, if the ground will permit.

The foil advantages neareft the furface is the belt; and by fuch ploughing, it is always kept near the furface, and never buried. In high ridges, the foil is accumulated at the crown and the furrows left bare. Such alteration of crown and furrow, is eafy where the ridges are no more but feven or eight feet broad. This mode of ploughing anfwers perfectly well in fandy and gravelly foils, and even in loam ; but it is not fafe in clay foil. In that foil, the ridges ought to be n feet wide, and 20 inches high ; to be preferred always in the fame form by call¬ ing, that is, by ploughing two ridges together, be¬ ginning at the furrow that feparates them, and plough¬ ing round and round till the two ridges be finilhed. By this method, the feparating furrow is railed a little higher than the furrows that bound the two ridges. But at the next ploughing, that inequality is correc¬ ted, by beginning at the bounding furrows, and going round and round till the ploughing of the two ridges be completed at the feparating furrow. 4. Clearing Ground of Weeds. For this purpofe a new inftrument, termed a cleaning Cleaning harrow, has been introduced by Lord Kames, and is harrow. ; ftrongly recommended (b). It is one entire piece | like the firft of thofe mentioned above, confifting ol s‘ ’ j feven bulls, four feet long each, two and one-fourth inches broad, two and three-fourths deep. The bulls are united together by Iheths, fimilar to what are men¬ tioned above. The intervals between the bulls being three and three-fourths inches, the breadth of the whole harrow is three feet five inches. In each bull are in¬ fected eight teeth, each nine inches free below the wood, and diftant from each other fix inches.

By this mode of ploughing, each ridge may be made of 40, or 50 or 60 yards in breadth, without any great inconvenience ; for although fome time will be loft in turning at the ends of thefe broad ridges, yet, as this operation is only to be once performed in this manner, the advantage that is reaped by having few open furrows, is more than fufficient to counter- {b} Iq his CantJeman Farmer; to which performance the pradlical part of this article is materially indebted.. 1 ; Part II.

The difference between culmiferous and leguminous plants with refpedt to the effects they produce in the foil, will be infilled on afterward, in the fedlion concerning rotation of crops. As the pre- fent fection is confined to the propagation of plants, it falls naturally to be divided into three articles : firlt. Plants cultivated for fruit; fecond, Plants cultivated, for roots; third, Plants cultivated for leaves. I. Plants Cultivated for Fruits I 1. Wheat and Rye. _ I 5,2®’ Any time from the middle of April to the middle Fallowing*-' of May, the fallowing for wheat may commence. The for wheaWj moment Ihould be chofen, wdien the ground, beginning to dry, has yet fome remaining foftnefs : in that con¬ dition, the foil divides ealily by the plough, and falls into fmall parts. This is an effential article, deferving the ftridlell attention of the farmer.. Ground plough¬ ed too wet, rifes, as we nuhole-fur, as when pafture- ground is ploughed where ploughed too dry, it rifes in great lumps, which are not reduced by fubfequent ploughings ; not to mention, that it requires double force to plough ground too dry, and that the plough is often broken to pieces.. When the ground is in pro¬ per order, the farmer can have no excufe for delaying, a Angle minute. This firft courfe of fallow muft, it is true, yield to the barley-feed ; but as the barley-feed is commonly over the firft week of May, or fooner, the feafon.muft be unfavourable if the fallow cannot be reached by the middle of May. As clay foil requires high ridges, thefe ought to be. cleaved at the firft ploughing, beginning at the furrow, and ending at the crown. This ploughing ought to be as deep as the foil will admit,: and water-fufrowing ought inftantly to follow; fog if rain happen before water-furrowing, it ftagnates in the furrow, neceffarily delays the fecond ploughing till that part of the ridge be dry, and prevents the furrow from.being mellowed and roafted by the fun. If this firft ploughing be well executed, annual weeds will rife in plenty. About the firft week of June, the great brake wall loofen and reduce the foil, encourage a fecond crop of annuals, and raife to the furface the roots of weeds moved by the plough. Give the weeds time to fpring, which may be in two or three weeks. Then proceed to the fecond ploughing about the beginning of July which muft be crofs the ridges, in order to reach all the flips, of the former ploughing.

The deftruc- ' tion of weeds is a capital article in fallowing : yet fo blind are people to their intereft, that nothing is more common than a fallow field covered with charlock and wild muftard, all in, flower, and 10 or 12 inches high. The field having now received two harrowings and two breakings, is prepared for manure, whether lime or dung, which without delay ought to be incorporated with the foil by a repeated harrowing and a gathering Drefling loam for wheat.

This ought to be about the beginning of butt of their neighbours merriment for adopting fo September, and as foon after as you pleafe the feed may be fown. As in ploughing a clay foil it is of importance to prevent poaching, the hinting furrows ought to be done with two horfes in a line. If four ploughs be employ¬ ed in the fame field, to one of them may be allotted the care of finifliing the hinting furrows. Loam, being a medium between fand and clay, is of all foils the fitteft for culture, and the leaft fubjeft to chances. It does not hold water like clay; and when wet, it dries fooner. At the fame time> it is more retentive than fand of that degree of moifture which promotes vegetation. On the other hand, it is more fubjeft to couch-grafs than clay, and to other weeds; to deftroy which, fallowing is ftill more necelfary than in clay. Beginning the fallow about the firft ©f May, or as foon as barley-feed is over, take as deep a furrow as the foil will admit. Where the ridges are fo low and narrow as that the crown and furrow can be changed alternately, there is little or no occafion for water fur¬ rowing. Where the ridges are fo high as to make it proper to cleave them, water-furrowing is proper. The fecond ploughing may be at the diftance of five weeks. Two crops of annuals may be got in the interim, the fii ft by the brake and the next by the harrow; and by the fame means eight crops may be got in the feafon. The ground muft be cleared of couch-grafs and knot- grafs roots, by the cleaning harrow deferibed above. The time for this operation is immediately before the manure is laid on. The ground at that time being in its loofeft ftate, parts with its grafs roots more freely than at any other time. After the manure is fpread, and incorporated wdth the foil by brakeing or harrow¬ ing, the feed may be fown under furrow, if the ground hang fo as eafily to carry off the moifture.

They had, however, confiderably better corn and larger crops than their neighbours : this, together with the faving in feed, engaged more to follow them: while fome ingenious perfons, ob- ferving its great advantage, recommended and pub- liftied its utility in the Norwich papers. Thefe re¬ commendations had their effect. The curiofity and inquiry of the Norfolk farmers (particularly round Norwich) were excited, and they found fufficient rea- fon to make general experiments. Among the reft was one of the largeft occupiers of lands in this county, who fet 57 acres in one year. His fuccefs, from the vifible fuperiority of his crop, both in quantity and quality, was fo great, that the following autumn he fet 300 acres, and has continued the praftice ever fince. This noble experiment eftabliftied the praftice, 127 and was the means of introducing it generally among A capita! the intelligent farmers in a very large diftridl of land; imPro.vc* there being few who now fow any wheat, if they can gncuiture* procure hands to fet it. It has been generally obferved, that although the fet crops appear very thin during the autumn and winter, the plants tiller and fpread prodi- gioufly in tbe fpring. The ears are indifputably lar¬ ger, without any dwarfifti or fmall corn ; the grain is of a larger bulk, and fpecifically heavier per bufhel than when fown. The lands on which this method is particularly pro- fperous, are either after a clover ftubble, or on which trefoil and grafs-feed were fown the fpring before the 12S laft. Thefe grounds, after the ufual manuring, are Method, once turned over by the plough in an extended flag or turf, at ten inches wide ; along which a man, who is called a dibbler, with two fetting-irons, fome what big¬ ger than ram-rods, but confiderably bigger at the lower end, and pointed at the extremity, fteps back¬ wards along the turf and makes the holes about four in- it rough without harrowing has two advantages : it ches afunder every way, and an inch deep.

But if it lie flat, it ought to be fmoothed with a flight harrow after the feed is fown, which will facilitate the courfe of the rain from the crown to the furrow. A fandy foil is too loofe for wheat. The only chance . for a crop is after red clover, the roots of which bind the foil; and the inftruftions above given for loam are applicable here. Rye is a crop much fitter for fandy foil than wheat ; and, like wheat, it is generally fown after a fummer-fallow. Laftly,'Sow wheat as foon in tbe.month of Oftober as the‘ground is ready. When fown a month more early, it is too forward in the fpring, and apt to be hurt by froft; when fown a month later, it has not time to holes the droppers (women, boys, and girls) drop two grains, which is quite fufficient. After this, a gate bufhed with thorns is drawn by one horfe over the land, and clofes up the holes. By this mode, three pecks of grain is fufficient for an acre ; and being im¬ mediately buried, it is equally removed from vermin or the power of froft. The regularity of its rifing gives the beft opportunity of keeping it clear from weeds, by weeding or hand-hoeing. • ^ Wheat-fetting is a method peculiarly beneficial when Peculiar corn is dear ; and, if the feafon be favourable, may, advantages, be prahtifed with great benefit to the farmer. Sir Thomas Beevor of Hethel-Hall in Norfolk, found the produce to be two buftiels per acre more than from the wheat which is fown ; but having much lefs fmall corn root before froft comes on, and froft fpews it out of intermixed with it, the fample is better, and always the ground.

Our reafon for this, as well as for print¬ ing Mr B’s letter, was rather to excite decifive trials by ingenious perfons, than from any expeftation of the practice ever becoming a general one. General, in¬ deed, it never can be. A fufficient number of hands could not be found to do it. Unkindly feafons at the time of tranfplanting and dividing the roots would fre¬ quently endanger and injure, if not deftroy the crops. But admitting the mode generally practicable, we very much doubt whether-all the advantages he has enumera¬ ted would be derived from this mode of culture. Why fhould dividing and tranfplanting the roots of wheat caufe the crop to be early, or afford a certainty of its • being a good one ? We cannot think that le/s manure is neceffary in this method, than either in drilling or . , n 1 j perhaps a triple quantity of what is reaped either by drilling, or by the broad-caft hufbandry. 5.

That in general he has found the diftance of nine inches every way a very proper diftance for fetting out the plants at; but recommends them to be tried at o- ther fpaces, fuch as fix, eight, or even 12 inches. 8. That he conceives an earlier crop may be obtain¬ ed in this manner than can be obtained by any other mode of cultivation. 9. That a clean crop may alfo be procured in this way, becaufe if the land be ploughed immediately be¬ fore the plants are fet out, the corn will fpring much quicker from the plants than the weeds will do from their feeds, and the cord will thereby bear down the growth of the weeds. 10.

Laftly, Mr Bogle has hinted at a fecondary objeef O o 2 which A G R I C U which he has in view, from this mode of cultivation, which he apprehends may in time, with a fmall degree of attention, prove extremely advantageous to agricul¬ ture.—It is, that in the firft place, the real and intrin- fic value of different kinds of grain may be more ac¬ curately afcertained by making a comparifon of it with a few plants of each kind fet out at the fame time, than can be done when fown in drills or, broad-caft ; and when the moll valuable kinds of wheat, oats, or barley, are difcovered, he ftates, that in a very fhort time (not exceeding four or five years) a fufficient quantity of that valuable kind may be procured to fup- ply the kingdom with feed from a fingle grain of each kind; for he calculates, that 47,000 grains of wheat may be produced by divifibility in two years and three months. Upon thefe propofitions the Society obferves, “ That although Mr Bogle appears to be too fanguine in his expectations of feeing his plan realized \n general prac¬ tice, it certainly merits the attention of Gentlemen Farmers. We wifh them to make fair experiments, and report their fuccefs. Every grand improvement has been, and ever will be, progreffive. They muft necef- farily originate with gentlemen ; and thence the circle is extended by almoll imperceptible degrees over pro¬ vinces and countries. At all events, Mr Bogle is juftly intitled to the thanks of the Society, and of the pub¬ lic, for the great attention he has paid to the fubjeft.” 2. Oats. As winter-ploughing enters into the culture of oats, we muft remind the reader of the effeft 'of froft upon • tilled land, tilled land. Providence has negleCted no region in¬ tended for the habitation of man. If in warm cli¬ mates the foil be meliorated by the fun, it is no lefs meliorated by froft in cold climates; Froft aCts upon water, by expanding it into a larger fpace. Froft has^ no effeft upon dry earth ; witnefs fand, upon which it it makes no impreffion. But upon wet earth it ads moft vigoroufly: it expands the inoifture, which re¬ quiring more fpace puts every particle of the earth out of its place, and feparates them from each other. In that view, froft may be confidered as a plough fuperior to any that is made, or can be made, by the hand of man : its aftion reaches the minuteft particles; and, by dividing andr feparating them, it renders the foil loofe and friable. This operation is the moft remarkable in tilled land, which gives free accefs to froft. With re- fpeCl to clay-foil in particular, there is no rule in huf- bandry more eflential than to open it before winter in hopes of froft. It is even advifable in a clay-foil to leave the ftubble rank ; which, when ploughed in be¬ fore winter, keeps the clay loofe, and admits the froft into every cranny. To apply this doftrine, it is dangerous to plough clay-foil when wet; becaufe water is a cement for clay, and binds it fo as to render it unfit for vegetation. It is, however, lefs dangerous to plough wet clay before winter than after. A fucceeding froft corrects the bad effefts of fuchploughing; a fucceeding drought increafes 138 thern* Culture of The common method is, to fowoats on new-plough- oats. ed land in the month of March, as fbon as the ground is tolerably dry.

But the preferable method, efpecially in clay-foil, is * to turn over the fielcbafter harveft, and to lay it open to the influences of froft and air, which leflen the te¬ nacity of clay, and reduce it to a free mould. The fur- face-foil by this means is finely mellowed for reception of the feed ; and it would be a pity to bury it by a fe- cond ploughing before fowing. In general, the bulk of clay-foils are rich ; and fkilful ploughing without dung, will probably give a better crop, than unlkilful' ploughing with dung. Hitherto of natural clays. We muft add a. word of ' carfe-clays which are artificial, whether left V by the fea, or fweeped down ’ from higher grounds' by rain. The method commonly ufed of drdTmg_carfe-clay for ■ oats, is, not to ftir it till the ground .be dry in the fpring, which feldom happens before the firft of March,. and the feed is fown as foon after as the ground is fuffi- ciently dry for its reception., Froft has T a ftronger effedt on fuch clays than on natural clay. And if the field be laid open before winter, it is rendered fo loofe by froft as to be foon drenched in water. The particles at the fame time are fo fmalt, as that the firft drought in fpring makes the furface cake or cruft. The difficulty of reducing this, craft into mould for covering the oat- feed, has led farmers to delay ploughing till the month of March; But we are taught by experience, that this foil ploughed before winter, is fooner dry than when • the ploughing is delayed till fpring ; and as early fow-. ing is a great advantage, the objettion of the fuperfi- cial crafting is eafily removed by the firft harrow above deferibed, which will produce abundance of mould for covering the feed. The ploughing before winter not only procures early fowing, but has another advantage: the furface-foil that had been mellowed during winter by the fun, froft, and wind, is kept above. • The dreffing a loamy foil for oats differs little from dreffing a clay foil, except in the following particular, that being lefs hurt by rain, it requires not high ridges, , and therefore ought to be ploughed crown and furrow alternately. Where there is both clay and loam in a farm, it is ; obvious from what is faid above, that the ploughing of the clay after harveft ought firft to be difpatched.. If both cannot be overtaken that feafon, the loam may be delayed till the fpring with lefs hurt. Next of a gravelly foil; which is thereverfe of clayy as it never fuffers but from want of moifture. Such a . foil ought to have no ridges; but be ploughed circularly: from the centre to the circumference, or from the cir¬ cumference to the centre. It ought to be tilled after harveft : and the firft dry weather in fpring ought to be laid hold of to fow, harrow, and roll; which will pre-. ferve it in fap. The culture of oats is the fimpleftof all; That grain, is probably a native of Britain : it will grow on the worft foil with very little preparation. For that reafon, before turnip was introduced, it was always the firft' crop upon land broken up from the ftate of nature. Upon fuch land, may it not be a good method, to build upon the crown of every ridge, in the form: of a wall, all the furface-earth, one fod above ano¬ ther, as in a fold for ffieep? After ftanding in this form all the fummer and winter, let the walls be thrown down, and the ground prepared for oata. This wilh fecure AGR ICULTURE. 139 fecure one or two good crops ; after which the land may be dunged for a crop of barley and grafs-feeds. This method may anfwer in a farm where manure is fcanty.. 3. B A R L E Y. Iture of This is a culmiferous plant that requires a mellow ■leV- foil. Up on that account, extraordinary care is requi- fite where it is to be fown in clay. The land ought to be ftirred immediately after the foregoing crop is re¬ moved, which lays it open to be mellowed with the froft and air. In that view, a peculiar fort of plough- Sbbing. ing has been introduced, termed rilbing; by which the greatefl. quantity of furface pofiible is expofed to the air and froil. The obvious objedtion to this method is, that half of the ridge is left unmoved. And to ob¬ viate that objeftion, the following method is offered, which moves the whole foil, and at the fame time ex- poles the fame quantity of furface to the froft and air.- As foon as the former crop is off the field, let the ridges be gathered with as deep a furrow as the foil, wiir admit, beginning at the crown and ending at the furrows. This ploughing loofens the whole foil, gi¬ ving free accefs to the air and froft. Soon after, begii 293 better | tethod. prevents thefe noxious effedts. By the two ploughings Pradhcc. ^ the whole foil is opened, admitting freely air and froft;'1 v * and the multitude of furrows lays the furface perfedtly dry, giving an early opportunity for the barley-feed.— But further, as to the advantage of this method: When it is proper to fow the feed, all is laid flat with the brake, which is an eafy operation upon foil that is dry and pulverized; and the feed-furrow which fuc- ceeds, is fo {hallow as to bury little or none of the fur- face-earth : whereas the ftirring for barley is common¬ ly done with the deepeft furrow; and confequently bu-.. l4^ _ ries all the furface-foil that was mellowed by the froft. ment and air. Nor is this method more expenfive; becaufe feed in a the common ribbing muft always be followed with a dry feafem ftirring furrow, which is fayed in the method recom¬ mended. Nay, it is lefs expenfive ; for after common . ribbing, which keeps in the rain water, the ground is commonly fo foured, ,as to. make the ftirring .a labo- - rious work.. It is well known that barley is lefs valuable when it does not ripen equally ; and that barley which comes up fpeedily in a dufky foil, muft gain a great advantage, over feed-weeds. Therefore, firft take out about one- third of the contents of the facks of feed barley or bear, to allow for the fwelling of the grain. Lay the a fecond ploughing in the following manner. Let the facks with the grain to fteep in clean water ; let it lie field be divided by parallel dinea crofs the ridges,. witL covered with it for at leaft 24 hours.

Plough the other intervals only the .fower muft put in a fourth or a third more feed in bulk than ufual .of dry grain, as-the grain is fwelled in that proportion : harrow it in as quickly as in the fame manner.. As by this operation the furrows poffible after it is- fbwn ; -and though not necefiary. of the ridges, will be pretty much .filled up, let them be cleared and water-furrowed without delay. By this method, the held will be left waving like a plot in a kitchen-garden, ridged up for winter. In this form, the field is kept perfedtly dry; for. befide the capital furrows that feparate the ridges, every ridge has a number of crofs furrows that carry the rain in- ftantly to the capital furrows. In hanging grounds retentive of moifture, the parallel lines above mention¬ ed ought not to be perpendicular to the furrows of the give it the benefit of frefh furrow, if convenient, may expedt it up in a fortnight at fartheft.-, The following experiment by a correfpondent of the • Bath Society being canfidered . as , a, .-very interefting one, is here fubjoinetL. 144 , ‘‘'The laft fpring (1783) being remarkably dry, I Important v foaked my feed-barley in the black water taken from a e3CPen- refervoir which conftantly receives the draining of my fced-barkyo > dung-heap and ftables.

Loam or fand may be ftirred a little moift: better, however, delay a week or two, than to ftir a loam when moift. Clay muft never be ploughed moift, even tho’ the feafon ffiould efcape altogether. But this will fel- dom be neceflary; for not in one year of 20 will it hap¬ pen, but that clay is dry enough for ploughing fome time in May. Fro ft may correft clay ploughed wet after harveft ; but ploughed wet in the fpring, it unites into a hard mafs, not to be diffolved but by very hard labour. On the cultivation of this grain we have the follow- T46 ing obfervations by a Norfolk farmer. Mifcellane- The beft foil, he obferves, is that which is dry and 0113 otiler- healthy, rather light than ftiff, but yet of fufficient tenacity and ftrength to retain the moifture. On this cultivation1 kind of land the grain is always the beft bodied and of barley, coloured, the nimbleft in the hand, and has the thin- neft rind. Thefe are qualities which recommend it raoft to the maltfter. If the land is poor, it ffiould be dry and warm ; and when fo, it will often bear better corn than richer land in a cold and wet fituation. In the choice of your feed, it is needful to obferve, that the beft is of a pale lively colour, and brightiffi caft, without any deep rednefs or black tinge at the tail. If the rind be a little ffirivelled, it is the better; for that flight ffirivelling proves it to have a thin flcin, and to havp fweated in the mow. The neceffity of a change of feed by not fowing two years together what grew bn the fame foil, is not in any part of hufbandry more evident than in the culture of this grain, which, if not frequently changed, will grow coarfer and coar- fer every fucceeding year. It has generally been thought that feed-barley would be benefited by fteeping ; but liming it has, in many inftances, been found prejudicial. Sprinkling a little foot with the water in which it is fteeped has been of, ;great fervice, as it will fecure the feed from infedts. In a very dry feed-time, barley that has been wetted for malting, and begins to fprout, will come up fooner, and produce as good a crop as any other. If you fow after a fallow, plough three times at leaft. At the firft ploughing, lay your land up in fmall ridges, and let it remain fo during the winter, for the froft to mellow it; the fecond ploughing ffiould be the begin¬ ning of February. In March fplit the ridges, and lay the land as flat as poffible, at the fame time harrowing it fine. But in ftrong wet lands (if you have no other for barley) lay it round, and make deep furrows to re¬ ceive the water. “ I have often (continues he), taken the following method «ith fuccefs : On lands tolerably manured, I fowed clover with my barley, which I reaped at har- . vdt; and fed the clover all the following winter, and from fpring to July, when I fallowed it till the fol¬ lowing fpring, and then fowed it-with barley and clo¬ ver as before. Repeating this method every year I had very large crops, but w ould not recommend this prac¬ tice on poor light land. “ We fow on our lighteft lands in April, on our iRoilt lands in May; finding that thofe lands which are 3 the moft fubjeft to weeds produce the beft crops when Pradtice. fown late. u—y—a —■ “ The common method is to fow the barley-feed broad-caft at two fowings ; the firft harrowed in once, the fecond twice; the ufual allowance from three to Tour buffiels per acre. But If farmers could be pre- ■ ■ j vailed on to alter this practice, they would foon find their account in it. Were only half the quantity fown equally, the produce would be greater, and the corn lefs liable to lodge : For when com ftands very clofe, the ftalks are drawn up weak; and on that account are lefs capable of refilling the force of winds, or fupport- ing themfelves under heavy rains. “ Fropi our great fuccefs in fetting and drilling wheat, fome of our farmers tried thefe methods with barley ; but did not find it anfwer their expectations, except on very rich land. “ I have myfelf had 80 ftalks on one root of Barley, which all produced good and long ears, and the grain was better than any other; but the method is too ex- penfive for general praCtice. In poor land, fow thin, or your crop will be worth little. Farmers who do not reafon on the matter, will be of a different opinion; but the fad is indifputable.” When the barley is fowed and harrowed in, he ad- vifes that the land be rolled after the firft ffiower of rain, to break the clods. This will clofe the earth about the roots, which will be a great advantage to it in dry weather. When the barley has been up three weeks or a month, it is a very good way to roll it again with a heavy roller, which will prevent the fun and air from penetrating the ground to the injury of the roots. This rolling, before it branches out, will alfo caufe it to tiller into a greater number of ftalks ; fo that if the plants be thin, the ground will be thereby filled, and the ftalks ftrengthened. If the blade grows too rank, as it fometimes will in a warm wet fpring, mowing is a much better method than feeding it down with fheep ; becaufe the fcythe takes off only the rank tops, but the ffieep being fond of the fweet end of the ftalk next the root, will often bite fo clofe as to injure its future growth. 4.

Probably, in hot dry fummers, a crop of vetches might even be mown for hay early enough to introduce a crop of this grain after it. In the year 1780, about feven acres of a fandy foil on art IT.

Ivcinta- The vegetation appeared in five or fix days, as is 5 of.t,lls conftantly the cafe be the weather wet or dry. The ;)PPinb- growth vvas fo rapid, that the fern, with which this land greatly abounded, was completely kept under. About the middle of September the crop was mown, but by reafon of a great deal of rain about that time, it was not fecured until the beginning of Oftober; hence a lofs of great part of the grain by fhedding, as well as fome eaten by birds. However, there were faved about 24 Winchefter bujfhels per acre ; and, not- withftanding its long expofure to the weather, recei¬ ved no fort of damage, only perhaps that the fineft and moft perfect grain was the firft to fall from the plant. The ground after this had almoft the appear¬ ance of a fallow, and was immediately ploughed. When it had lain a moderate time to meliorate, and to receive the influences of the atmofphere, it was har¬ rowed, fown with Lammas wheat, and ploughed in under furrow, in a contrary direftion to the firft | ploughing. Thus a piece of land, which in the month of April was altogether in a ftate of nature, in the following November was feen under a promifing crop of what is well ftyled the king of grain, and this w’ithout the aid of manure, or of any very great degree of tillage. Nor was the harveft by any means deficient; for feveral perfons converfant in fuch things eftimated the produce from 26 to 30 buftiels per acre. As foon as the wheat crop was taken off, the ground had one ploughing, and on the firft of September following was- fown with turnip-feed. The turnips were not large, but of an herbage fo abundant as in the following fpring to fupport 120 ewes with their lambs, wrhich were fed on it by folding four weeks. After this it was manured with a compofition of rotten dung and natural earth, about 20 putt loads per acre, and plant¬ ed with potatoes. The crop fold for L. 138, befides a confiderable number ufed in the family, and'a quan¬ tity referved with which ten acres were planted the following feafon. The enfuing autumn it was again fown with wheat, and produced an excellent crop. In the fpring of 1784, it was manured and planted with potatoes, as in the preceding inftance; the crop (tho’ tolerably good) by no means equal to the former, pro¬ ducing about 100 facks per acre only. In fpring 1785, -the land was now for a third time under a crop of \tfheat, it being intended to try how far this mode of alternate cropping, one year with potatoes and another with wheat, may be carried.. From the fuceefs of the preceding and other expe¬ riments, by Nehemiah Bartley, Efq; of Briftol, as de¬ tailed in the Bath Society Papers, it would feem, that the culture of this plant ought in many cafes to be a- dopted inftead of a fummer-fallowing: for the crop produced appears not only to he fo much clear gain in refpeft to fuch practice, but alfo affords a confiderable quantity of ftraw for fodder and manure ; befide that L T U R E. 295 a fummer-fallowing is far from being fo advantageous Praftke. a preparation for a fucceeding crop. 1111 ■’ 5. Beans. The propereft foil for beans is a deep and moift clay. Culture of There was lately introduced into Scotland a method beans, of fowing beans with a drill-plough, and horfe-hoeing the intervals; which, befide affording a good crop, is a dreffing to the ground. But as that method is far from being general, we keep in the common track. As this grain is early fown, the ground intended for it fhould be ploughed before winter, to give accefs to the froft and air ; beneficial in all foils, and neceffary in a clay foil. Take the firft opportunity after Ja¬ nuary when the ground is dry, to loofen the foil with the harrow firft deferibed, till a mould be brought up¬ on it. Sow the feed, and cover it with the fecond harrow. The third will fmooth the furface, and cover the feed equally. Thefe harrows make the very beft figure in fowing beans; which ought to be laid deep in the ground, not lefs than fix inches. In clay foil, the common harrows are altogether infufficient. The foil, which has rerted long after ploughing, is render¬ ed compact and folid : the common harrows Ikim the furface: the feed is not covered; and the firft hearty ftiower of rain lays it-above ground. Where the far¬ mer overtakes not the ploughing after harveft, and is reduced to plough immediately before fowing, the plough anfwers. the purpofe of the firft harrow ; and the other two will complete the work. But the labour of the firft harrow is-ill faved; as the ploughing before winter is a fine preparation, not only for beans, but for grain, of every kind. If the ground ploughed be-■ fore winter happen by fuperfluity of moifture to cake, the firft harrow going along the ridges, and crofting them, will loofen the furface, and give accefs to the air for drying. As foon as the ground is dry; fow with¬ out delaying a moment. If rain happen in the interim,., there is no remedy but patience till a dry day or two come. Carfe-clay, ploughed before winter, feldom fails to cake. Upon that account, a fecond ploughing is ne¬ ceffary before fowing; which ought to be performed with an ebb furrow,. in order to keep the froft-mould as near the furface as pofiible. To cover the feed with the plow is exprefled by the phrafe A? fow under fur. row. The clods, raifed in this ploughing are a fort, of (helter to the young plants in the chilly fpring- - months. The foregoing method will anfwer for loam. And - as for a fandy or gravelly foil,, it is altogether impro-- per for beans. Though we cannot approve the horfe-hoeing of beans, with the invervals that are commonly allotted for turnip, yet we would ftrongly recommend the drill¬ ing them atthe diftanceof 10 or 12 inches,. and keep¬ ing the intervals clean of weeds., This may be done by hand-hoeing, taking opportunity at the fame time to lay frelh foil to the roots of the plants. But as this is an expenfive operation, and hands are not always to be got, a narrow plough, drawn by a Angle horfe, might be ufed, with a mould-board on each fide to fcatter the earth. (a) A very rough piece of land, at that time juft inclofed. 296 A G R I G Practice, eartli upon the roots of the plants. This is a cheap and expeditious method: it keeps the ground clean ; and nourifhes the plants with frefh foil. As beans delight in a moiil foil, and have no end of growing in a moift feafon, they cover the ground totally when fown broadcaft, keep in the dew, and ex¬ clude the fun and air : the plants grow to a great height; but carry little feed, and that little not well ripened. This difplays the advantage of drilling ; which gives free accefs to the fun and air, dries the •ground, and affords plenty of ripe feed. * 6. Peas e. 150 Culture of Pease are- of two kinds ; the white, and the gray. • |>eafe. The cultivation of the latter only belongs to this place. There are two fpecies of the gray kind, diftinguifh- ed by their time of ripening. One ripens foon, and for that reafon is termed hot feed: the other, which is flower ■ in ripening, is termed cold feed. Peafe, a leguminous crop, is proper to intervene between two culmiferous crops; lefs for the profit of a peafe-crop, than for meliorating the ground. Peafe, however, in a dry feafon, will produce fix or feven bolls each acre ; but, in an ordinary feafon, they feldom reach above two, or two and a half. Hence, in a moift cli¬ mate, which all the weft of Britain is, red clover feems a more beneficial crop than peafe; as it makes as good winter-food as peafe, and can be cut green thrice du¬ ring fummer. A field intended for cold feed ought to be ploughed in October or November; and in February, as foon as the ground is dry, the feed ought to be fown on the winter-furrow. A field intended for hot feed ought to be ploughed in March or April, immediately before fowing. But if infefted with weeds, it ought to be al- fo ploughed in October or November. Peafe laid a foot below the furface will vegetate ; but the moft approved depth is fix inches in light foil, and four inches in clay foil; for which reafon, they ought to be fown under furrow when the ploughing is delayed till fpring. Of all grain, beans excepted, they are the leaft in danger of being buried. Peafe differ from beans, in loving a dry foil and a dry feafon. Horfe-hoeing would be a great benefit, could it be performed to any advantage 5 but peafe .grow expeditioufly, and foon fall over and cover the ground, which bars ploughing. Horfe-hoeing has ■little effedt when the plants are new fprung; and when they are advanced to be benefited by that culture, their length prevents it. Faft growing at the fame time is ■the caufe of their carrying fo little feed : the feed is buried among the leaves; and the fun cannot penetrate to make it grow and ripen. The only practicable re¬ medy to obtain grain, is thin fowing ; but thick fowing produces more ftraw, and mellows the ground more. Half a boll for an Englifh acre may be reckoned thin fowing ; three firlots, thick fowing. Notwithftanding what is faid above, Mr Hunter, a noted farmer in Berwickftiire, began fome time ago to fow all his peafe in drills; and never failed to have great crops of corn as well as of ftraw. He fowed double rows at a foot interval, and two feet and an half be¬ tween the double rows, which admit horfe-hoeing. By that method, he had alfo good crops of beans on light land. N° 8. 4 U L T U R E. Part It Peafe and beans mixed -are often fown together, in Pra&iee, order to catch different feafons. In a moift feafon, the v""* beans make a good crop ; in a dry feafon, the peafe. The growth of plants is commonly checked by drought in the month of July ; but promoted by rain in Auguft. In July, grafs is parched ; in Auguft, it recovers verdure. Where peafe are fo far advanced in the dry feafon as thfit the feed begins to form, their growth is indeed checked, but the feed continues to fill. If only in the bloffom at that feafon, their growth is checked a little; but they become vigorous again in Auguft, and continue growing without filling till flop¬ ped by ffoft. H?nce it is, that cold feed, which is early fown, has the beft chance to produce corn : hot feed, which is late fown, has the beft chance to pro¬ duce ftraw. The following method is pradlifed in Norfolk, for fowing peafe upon a dry light foil, immediately opened from pafture. The ground is pared with a plough ex¬ tremely thin, and every fod is laid exadtly on its back. In every fod a double row of holes is made. A pea dropt in every hole lodges in the flay’d ground imme¬ diately below the fod, thrufts its roots horizontally, and has fufficient moifture. This method enabled Norfolk farmers, in the barren year 1740, to furnifh white peafe at 12 s. per boll. II. Plants cultivated for Roots. \_See alfo Art. III.'] 1. Turnip. Turnip delights in a gravelly foil; and there it can Culture J be raifed to the greateft perfection, and with the leaft turnip, hazard of mifcarrying. At the fame time, there is no foil but will bear turnip when well prepared. No perfon ever deferved better of a country, than he who firft cultivated turnip in the field. No plant is bet¬ ter fitted for the climate of Britain, no plant profpers better in the coldeft part of it, and, no plant contributes more to fertility. In a word, there has not for two centuries been introduced into Britain a more valuable improvement. Of all roots, turnip requires the fineft mould; and to that end, of all harrows froft is the beft. In order to give accefs to froft, the land ought to be prepared by ribbing after harveft, as above diredled in preparing land for barley. If the field be not fubjedl to annuals, it may lie in that ftate till the end of May ; otherwife the weeds muft be deftroyed by a brakeing about the )■ middle of April; and again in May, if weeds rife. The firft week of June, plough the field with a fhallow furrow. Lime it if requifite, and harrow the lime into the foil. Draw Angle furrows with intervals of three feet, and lay dung in the furrows. Cover the dung fuf- ficiently, by going round it with the plough, and form- -ing the three-feet fpaces into ridges. The dung comes thus to lie below the crown of every ridge. j j- The feafon of fowing muft be regulated by the time Seafon ail n intended for feeding. Where intended for feeding in method Jbfi November, December, January, and February, the IowinS- QR feed ought, to be fown from the ift to the 20th of June. Where the feeding is intended to be carried on to March, April, and May, the feed muft not be fown till the end of July. Turnip fown earlier than above direfted, flowers that very fummer, and runs faft to feed; which renders it in a good meafure unfit for food. 4 'Part II. AGRICULTURE. Pra(Slice, food. If fown much later, it does not apple, and there is no food but from the leaves. Though by a drill-plough the feed may be fown of any thicknefs, the fafefl: way is to fow thick. Thin fowing is liable to many accidents, which are far from being counterbalanced by the expence that is faved in thinning. Thick-fowing can bear the ravage of the black fly, and leave a fufficient crop behind. It is a pro- teftion againil drought, gives the plants" a rapid prb- grefs, and eftablifhes them in the ground before it is neceffary to thin them. The fowing turnip broadcaft is univerfal in England, and common in Scotland, though a barbarous practice. The eminent advantage of turnip is, that beflde a pro¬ fitable crop, it makes a moft complete fallow ; and the latter cannot be obtained but by horfe-hoeing. Upon that account, the fowing turnip in rows at three feet diftance is recommended. Wider rows anfwer no pro¬ fitable end, ftraiter rows afford not room for a horfe to walk in. When the turnip is about four inches high, annual weeds will appear. Go round every interval with the flighteft furrow pofiible, at the diitance of two inches from each row, moving the earth from the rows toward the middle of the interval. A thin plate of iron muft be fixed on the left fide of the plough, to prevent the earth from falling back and burying the turnip. Next, let women be employed to weed the rows with their fingers ; which is better, and cheaper done, than with the hand-hoe. The hand-hoe, be- fide, is apt to difturb the roots of the turnip that are to Hand, and to leave them open to drought by removing the earth from them. The ftanding turnip are to be at the diftance of twelve inches from each other : a greater diftance makes them fwell too much ; a lefs di¬ ftance affords them not fufficient room. A woman foon comes to be expert in finger-weeding. The fol¬ lowing hint may be neceffary to a learner. To fecure the turnip that is to ftand, let her cover it with the left hand ; and with the right pull up the turnip on both fides. After thus freeing the ftanding turnip, fhe may fafely ufe both hands. Let the field remain in this ftate till the appearance of new annuals make a fecond ploughing neceffary ; which muft be in the fame fur¬ row with the former, but a little deeper. As in this ploughing the iron plate is to be removed, part of the loofe earth will fall back on the roots of the plants : the reft will fill the middle of the interval, and bury every weed. When weeds begin again to appear, then is the time for a third ploughing in an oppofite direc¬ tion, which lays the earth to the roots of the plants. This ploughing may be about the middle of Augufi ; after which, weeds rife very faintly. If they do rife, another ploughing will clear the ground of them. Weeds that at this time rife in the row, may be cleared with a hand-hoe, which can do little mifchief among plants diftant twelve inches from each other. It is cer¬ tain, however, that it may be done cheaper with the hand (a). And after the leaves of turnips in a row meet Vol. I. Parti. 297 together, the hand is the only inftrument that can be Practice, applied for weeding. e_—w In fwampy ground, the furface of which is beft re¬ duced by paring and burning, the feed may be fown in rows with intervals of a foot. To fave time, a drill- plough may be ufed that fows three or four rows at once. Hand-hoeing is proper for fuch ground ; be- caufe the foil under the burnt Jir^atum is commonly full of roots, which digeft and rot better under ground than when brought to the furface by the plough. In the mean time, while thefe are digefting, the aihes will fe¬ cure a good crop. In cultivating turnips to advantage, great care fliould Properties be taken to procure good, bright, nimble, and well-of Afferent dried feed, and of the beft kinds. forts of tur- The Norfolk farmers generally raife the oval white, 1 the large green-topp’d, and the red or purple-topp’d kinds, which from long experience they have found to be the moft profitable. The roots of the. green-topp’d will grow to a large fize, and continue good much longer than others. The red or purple-topp’d will alio grow large, and continue good to the beginning of February ; but the roots be¬ come hard and ftringy fooner than the former. The green-topp’d growing more above ground, is in more danger of fuftaining injury from fevere frofts than the red or purple, which are more than half covered by the foil; but it is the fofteft and fweeteft, when grown large, of any kind. We have feen them brought to ta¬ ble a foot in diameter, and equally good as garden turnips. Turnips delight in a light foil, confifting of fand and loam mixed ; for when the foil is rich and heavy, although the crop may be as great in weight, they will be rank, and run to flower earlier in fpring. Turnip-feed, like that of grain, will not do well OMerva- without frequent changing. The Norfolk feed is fent tions with to moft parts of the kingdom, and even to Ireland, but regar. RIG L. s. d. 120 o o 21 O O 5 0 0 L. 146 O O The field on which the above experiment was made, was an oat-ftubble in the autumn of 1783. In O6I0- ber it was ploughed, and left in a rough ftate during the winter. In April it was crofs-ploughed and har¬ rowed. On the 8th of May the field was marked out into beds or ridges eight feet wide, leaving a fpace of two feet wHe for an alley between every two ridges. The manure (a eompoft of liable dung, virgin earth, and fcrapings of a turnpike road) was then brought on the land, and depofited in fmall heaps on the centre of each ridge, in the proportion of about 30 cart-loads to each acre. A trench was - then opened with a fpade, breadth-way of the ridge, about four inches deep ; in this trench the potato-fets were placed, at the diitance of nine inches from each other; the dung was then fpread in a trench on the fets, and a fpace or plit of 14 inches in breadth, dug in upon them. When the plants I were about fix inches high, they were carefully hoed, I: and foon after the two feet intervals between the ridges were dug, and the contents thrown around the young- plants.

For a long time,.potatoes in Scotland were confined to the kitchen-garden ; and after they were planted in the field, it was not imagined at firft that they could be ufed after the month of December. Of late years, they have been found to anfwer even till April; which has proved' a great fupport to many a poor family, as they are eafily. cooked,, and require neither- kiln nor mill. But there ia no caufe for Hopping there. It is eafy to preferve them till the next crop : When taken cut of the ground, lay in the corner of a barn a quan- t tity that may ferve till April, covered from froll with dry llraw. prefied down: bury the remainder in a hole dug in dry ground, mixed with the hulks of dried oats, fand, or the dry leaves of trees, over which build a Hack of hay or corn. When the pit is opened for taking out the potatoes, the eyes of what have a ten¬ dency to pulh mull be cut out; and this cargo will ferve all the month of June. To be Hill more certain of making the old crop meet the new, the fetting of a fmall quantity may be delayed till June, to be taken U L T U R E. 301 up at the ordinary time before froft. This cargo, ha- Pradhce. ^ ving not arrived to full growth, will not be fo ready to ' v pulh as what are fet in April. If the old crop happen to be exhaulled before the new crop is ready, the interval may be fupplied by the po¬ tatoes of the new crop that lie next the futface, to be picked up with the hand 5 which, far from hurting the crop, will rather Improve it. 3. Carrot and Parsnip. . . *6? Of all roots, a carrot requires the deepell foil. It Culture of: ought at leall to be a foot deep, all equally good from c.arreU top to bottom. If fuch a foil be not in the farm, it may be made artificially by trench-ploughing, which brings to the furface what never had any communica¬ tion with the fun or air. When this new foil is fuffi- ciently improved by a crop or two with dung, it is fit for bearing carrots. Beware of dunging the year when the carrots are fown ; fur with frefh dung they feldom- efcape rotten feabs. v The only foils proper for that root,., are a loam and a fandy foil. The ground mull be prepared by the deepeft furrow that can be taken, the fooner after harveft the better immediately upon the bade of which, ai ribbing ought' to fucceed, as diredled for barley. At the end of March,, or beginning of April, which is the time of lowing the feed, the ground muft. be fmoothed with a brake. Sow the feed in drills, with intervals of a foot fof hand- hoeing : which is no expenfive operation where the ' crop is confined to an acre or two; but if the quantity of ground be greater, the intervals ought to be three, feet, in order for horfe-hoeing. In fiat ground without ridges, it may be proper to make parallel furrows with the plough, ten feet from each other, in order to'carry off any redundant moi- fture. At Parlington in Yorkfhire, from the end of Sep¬ tember to the firft of May, 20 work-horfes, four bul¬ locks, and fix milk-cows, were fed on the carrots that grew on three acres; and thefe animals never tafted any other food but a little hay. The milk was excel¬ lent and, over and above, 30 hogs-were fattened upon what was left by the other beafts. We have this fact from undoubted authority. , i68~‘ The culture of parfnips is the fame with that ofPaifiups, carrots. IIP. Plants cultivated for Leaves* or for both Leaves and Root. There are many garden-plants of thefe kinds. The plants proper for the field are cabbage red and white, colewort plain and curled, turnip-rooted cabbage,, and the root of fearcity; 169. 1. Cabbage is an interefting article in hufbandry. It Culture o, is eafily raifed, is fubject to few difeafes, refifts froft cabbage, more than turnip, is palatable to cattle, and fooner fills them, than turnip, carrot, or potatoesi The feafon for fetting cabbage depends on the, ufe it is intended for..

The late fetting of the plants retards their growth; by which means they have a vigorous growth the follow¬ ing fpring. And this crop makes an important link in the chain that connedts winter and fummer green food. Where cabbage for fpring-food happens to be negledfed, a few acres of rye, fown at Michaelmas, will fupply the want. After the lye is confumed, there is time fufficient to prepare the ground for turnip. And now to prepare a field for cabbage. Where _ the plants are to be fet in March, the field mull be made up after harveft, in ridges three feet wide. In that form let it lie all winter, to be mellowed with air and froft. In March, take the firft opportunity, be¬ tween wet and dry, to lay dung in the furrows. Cover the dung with a plough, which will convert the furrow into a crown, and confequently the crown into a fur¬ row. Set the plants Upon the dung, diftant from each other three feet. Plant them fo as to make a ftraight line crofs the ridges, as well as along the furrows, to which a gardener’s line ftretched perpendicularly crofs the furrows will be requifite. This will fet each plant at the diltance precifely of three feet from the plants that furround it. The purpofe of this accuracy is to give opportunity for ploughing, not only along the ridges, but crofs them. This mode is attended with three fignal advantages: it faves hand-hoeing, it is a more complete dreffing to the foil, and it lays earth neatly round every plant. If the foil be deep and compofed of good earth, a trench-ploughing after the preceding crop will not be amifs; in which cafe, the time for dividing the field into three-feet ridged, as above, ought to be immediately before the dunging for the plants. If weeds happen to rife fo clofe to the plants as not to be reached by the plough, it will require very little labour to deltroy them with a hand-hoe. Unlefs the foil be much infefted with annuals, twice ploughing after the plants are fet will be a fufficient drefiing. The firft removes the earth from the plants ; the next, at the diftance of a month or fo, lays it back. Where the plants are to be fet in July, the field mull be ribbed as diredted for barley. It ought to have a flight ploughing in June before the planting, in order to loofen the foil, but not fo as to bury the fur- face-earth ; after which the three feet ridges muft be formed, and the other particulars carried on as diredt- ed above with refpcdl to plants that are to be fet in , j0 March. Cultivation 2. As to the turnip-rooted callages, their importance of the tur- and value feem only to have been lately afcertained. cabba°es^ t^e Society Papers we have the following ac- s ' count of Sir Thomas Beevor’s method of cultivating them ; which from experience he found to be cheaper and better than any other. “ In the firft or fecond week of June, I fow the fame quantity of feed, hoe the plants at the fame fize, leave them at the fame diftance from each other, and treat them in all refpetts like the common turnip. In this method I have always obtained a plentiful crop of them ; to afcertain the value of which I need only in¬ form you, that on the 23d day of April laft, having then two acres left of my crop, found, and in great L T U R E. Part II. perfedlion, I divided them by fold hurdles into three Practice, parts of nearly equal dimenfions. Into the firft partv— I put 24 fmall bullocks of about 30 ftone weight each ,7l (141b. to the ftone), and 30 middle-fized fat wethers, Their utili- which, at the end of the firft week, after they had ty and va- eaten down the greater part of the leaves, and fomelue< part of the roots, I drifted into the fecond divifion, and then put 70 lean fheep into what was left of the firft; thefe fed off the remainder of the turnips left by the fat ftock; and fo they were drifted through the three divifions, the lean ftock following the fat as they wanted food, until the whole was confumed. “ The 24 bullocks and 30 fat wethers continued in the turnips until the 21ft of May, being exactly four weeks; and the 70 lean dreep until the 29th, which is one day over four weeks : fo that the two acres kept me 24 fmall bullocks and no dreep four weeks (not reckoning the overplus day of keeping the lean dreep) ; the value, at the rate of keeping at that feafon, cannot be eftimated in any common year at lefs than 4d. a-week for each dreep, and is. 6d. per week for each bullock, which would amount together to the firm of L,. 14 : 10 : 8 for the two acres. “ You will hardly, I conceive, think I have fet the price of keeping the dock at too high a rate ; it is be¬ neath the price here in almoft every fpring, and in this laft it would have coft double, could it have been pro¬ cured ; which was fo far from being the cafe, that hundreds of dreep and lambs here were loft, and the reft greatly pinched for want of food. “ You will obferve, gentlemen, that in the valua¬ tion of the crop above mentioned I have claimed no allowance for the great benefit the farmer receives by being enabled to fuffer his grafs to get into a forward growth, nor for the fuperior quality of thefe turnips in fattening his ftock ; both which circumftances muft ftamp a new and a great additional value upon them. But as their continuance on the land may feem to be injurious to the fucceeding crop, and indeed will de¬ prive the farmer totally of either oats or barley; fo to fupply that lofs I have always fown buck-wheat on the firft earth upon the land from which the turnips were thus fed off; allowing one budiel of feed per acre, for which I commonly receive from five to fix quarters per 1 acre in return. And that I may mot throw that part of my land out of the fame courfe of tillage with the reft, I fow my clover or other grafs-feeds with the buck-wheat, in the fame manner as with the oat or barley crops, and have always found as good a layer (ley) of it afterwards. “ Thus you fee, that in providing a moft incompa¬ rable vegetable food for cattle, in that feafon of the year in which the farmer is generally moft diftreffed, and his cattle almoft ftarved, a confiderable profit may like wife be obtained, much beyond what is ufually de¬ rived from his former practice, by the great produce and price of a crop raifed at fo eafy an expence as that of buck-wheat, which, with us, fells commonly at the fame price as barley, oftentimes more, and but very rarely for lefs. “ The land on which I have ufually fown turnip- rooted cabbages is a drymixed foil, worth 15 s. per acre.” To the preceding account the Society have fubjoin- ed the following note : “ Whether we regard the im- portancr Part II. if Practice, portance of the fubjeft, or the dear and practical in- ' formation which the foregoing letter conveys, it may be conlidered as truly interefting as any we have ever com been favoured with : and therefore it is recommended mendatlon *n ftrongeft manner to farmers in general, that they !by the Bath adopt a mode of practice fo decifively afcertained to -society. be in a high degree judicious and profitable.” To raife the turnip-rooted cabbage for tranfplanting, the bell; method yet difcovered is, to breaft-plough and burn as much old pafture as may be judged neceffary for the feed-bed; two perch well Hocked with plants will be fufficient to plant an acre.

Thefe plants will ftrike root in twenty-four hours, and a man a little accuftomed to planting, will plant with eafe 1800 or 2000 a-day. In the feed-bed, the plants, like all others, muff be kept clear of weeds : when they are planted out, after once hoeing, they will take care of themfelves, and fuffocate every kind of weed near them. The heft time to fow the feed is from the beginning of March to the middle of April: it is, however, ad- vifed to continue fowing every month until the begin¬ ning of July, in order to have a fucceflion of plants. Both leaves and roots have been extolled as excellent both for man and bead. This plant is faid not to be liable, like the turnip, to be deftroyed by infects, for no infedt touches it, nor is it affedted by exceffive drought, or the changes of feafons. Horned cattle, horfes, pigs, and poultry, are exceedingly fond of it when cut fmall. The leaves may be gathered every 12 or 15 days; they are from 30 to 40 inches long, by 22 to 25 inches broad.

To put all thefe pro¬ perties beyond doubt, however, further experiments are wanting. Sect. IV. Culture of Graft. The latter end of Auguft, or the beginning of Sep- tember, is the beft feafon for lowing grafs-feeds, as Of laying there is time for the roots of the young plants to fix d°WB fields themfelves before the (harp frofts fet in. It is fcarcet0 gra*®' neceffary to fay, that moift weather is beft for fowing; the earth being then warm, the feeds will vegetate im¬ mediately ; but if this feafon prove unfavourable, they will do very well the middle of March following. If you would have fine pafture, never fow on foul land. On the contraiy, plough it well, and clear it from the roots of couch-grafs, reft harrow, fern, broom, and all other noxious weeds. If thefe are fuffered to remain, they will foon get above, and deftroy your young grafs. Rake thefe up in heaps, and burn them on the land, and fpread the allies as a manure. Thefe ploughings and harrowings (hould be repeated in dry weather. And if the foil be clayey and vest, make fome under-drains to carry off the water, which, if fuf¬ fered to remain, will not only chill the grafs, but make it four. Before fowing, lay the land as level and fine as poffible. If your grafs-feeds are clean, ( which (hould: always be the cafe) three bufhels will be fufficient per acre. When fown, harrow it in gently, and roll it in with a wooden roller. When it comes up, fill up all the bare fpots by frelh feed, which, if rolled to fix it, will foon come up, and overtake the reft. In Norfolk they fow clover with their graffes, par¬ ticularly with rye-grafs; but this (hould not be done except when the land is defigned for grafs only three or four years, becaufe neither of thefe kinds will laft long in the land. Where you intend it for a continuance, it is better to mix only fmall white Dutch clover, or marie grafs, with your other grafs feed, and not more than eight pounds to an aefe. Thefe are abiding plants, fpread clofe on the furface, and make the fweefeft feed of any for cattle. In the following fpring, root up thiftles, hemlock, or any large plants that appear. The doing this while the ground is foft enough to per¬ mit your drawing them by the roots, and before they feed, will fave you infinite trouble afterwards. The common method of proceeding in laying down fields to grafs is extremely injudicious. Some fow barley with their graffes, which they fuppofe to be ufeful in (hading them, without coilfidering how much the com draws away the nourifhment from the land. Others take their feeds from a foul hay-rick; by which means, befides filling the land with rubbiffi and weeds, what they intend for dry foils may have come ^ from moift, where it grew naturally, and vice verfa. Differcnr The confequence is, that the ground, inftead of being kinds of covered with a good thick fward, is filled with grafs> plants unnatural to it. The kinds of grafs moft eligible for pafture-lands are, the annual-meadow, creeping, and fine bent, the fox-tails, and crefted dog’s-tail, the poas, the fefcucs, the vernal, oat- grafs, AGRICULTURE. Part IT; * Plate V, %• 7- grafs, and tlie ray, or rye-grafs. We do not, how¬ ever, approve of fowing all thefe kinds together ; for ■not to mention their ripening at different times, by •which means you can never cut them all in perfe&ion and full vigour, no kind, of cattle are fond of all alike. Horfes will fcarcely eat hay which oxen and cows will thrive upon ; fheep are particularly fond of fome kinds, and refufe others. The Darnel-grafs, if not cut before feveral of the other kinds are ripe, becomes fo hard and wiry in the ftalks, that few cattle care to eat it. Such gentlemen as wifh a particular account of the above-mentioned graffes, will be amply gratified in con¬ sulting Mr Stillingfleet on this fubjeft. He has treat¬ ed it with great judgment and accuracy, and thofe who follow his directions in the choice of their graffes will be under no fmall obligation to him for the valu¬ able information he has given them. The fubftance of his obfe'rvations are given in the article Grasses in this Dictionary. The graffes commonly fown for pafture, for hay, or to cut green for cattle, are red clover, white clover, ■yellow clover, rye-grafs, narrow-leaved plaintain com¬ monly called ribwort, faintfoin, and lucerne. Red clover is of all the molt proper to be cut green for fummer-food. It is a biennial plant when fuffered to perfeCt its feed; but when cut green, it will laft three years, and in a dry foil longer. At the fame time the fafeft courfe is to let it ftand but .a fingle year: if the fecond year's crop happen to be fcanty, it proves, like a bad crop pf peafe, a great encourager of weeds by the Ihelter it affords them. Here, as in all other crops, the goodnefs of feed is of importance. Choofe plump feed of a purple colour, becaufe it takes pn that colour when ripe. It is red when hurt in the drying, and of a faint colour when unripe. Red clover is luxuriant upon a rich foil, whether clay, loam, or gravel: it will grow even upon a moor, when properly cultivated. A wet foil is its only bane ; for there it does not thrive. To have red clover in perfection, weeds muff be ex¬ tirpated, and Hones taken off. The mould ought to be made as fine as -.harrowing can make it ; and the furface be fmoothed with a light roller, if not fuffi- ciently fmooth without it.' This gives opportunity for diftributing the feed evenly : which mull be covered by a fmall harrow with teeth no larger than that of a gar¬ den-rake, three inches long, and fix inches afunder*. In harrowing, the man Ihould-walk behind with a rope in his hand fixed to the back part of the harrow, ready to difentangle it from Hones, clods, turnip or cabbage- roots, which would trail the feed, and difplace it. Nature has not determined any precife depth for the feed of red clover more than of other feed. It will grow vigoroufly from two iitches deep, and it will grow when barely covered. Half an inch may be reckoned the moil advantageous pofition in clay foil, a whole inch in what is light or loofe. It is a vulgar error, that fmall feed ought to be fparingly covered. Milled by that error, farmers commonly cover their Clover- feed with a bufhy branch of thorn ; which not only covers it unequally, but leaves part on the furface to wither in the air. The proper feafon for fowing red-clover, is from the n° a. middle of April to the middle of May. It will fpring Practice. from the firH of March to. the end of AuguHbut fuch liberty ought not to be taken except from ne- ceffity. There cannot be a greater blunder in hufbandry, than to be fparing of feed. Ideal writers talk of fowing an acre with four pounds. That quantity of feed, fay they, will fill an acre with plants as thick as they ought to Hand. This rule maybe admitted where grain is the objeCl; but it will not anfwer with refpeft tp grafs. Grafs-feed cannot be fown too thick: the plants fliel- ter one another: they retain all the dew: and they muH puflx upward, having no room laterally. Obferve the place where a fack of peafe, or of other ,grain, has been fet down for fowing: the feed, dropt there acci¬ dentally grows more quickly than in the reH of the field fown thin out of hand. A young plant of clover, or of faintfoin, according to Tull, may be raifed to a great fize where it has room; but the field will not produce half the quantity. When red clover is fown for cutting green, there ought not to be lefs than 24 pounds to an acre. A field of clover is feldom too thick : the fmaller a Hem be, the more acceptable it is to cattle. It is often too thin j and when fo, the Hems tend to wood. || Red clover Is commonly fown with grain ; and the Of fowing | moil proper grain has been found by experience to beclovfr with! flax. The foil mufl be highly cultivated for flax as wellsrain’ as for red clover. The proper feafon of fowing is the fame for both ; the leaves of flax being very fmall, ad¬ mit of free circulation of air ; and flax being an early crop, is removed fo early as to give the clover time for growing. In a rich foil it has grown lb fafl, as to af¬ ford a good cutting that very year. Next to flax, barley is the belt companion to clover. The foil muH be loofe and free for barley; and fo it ought to be for clover: the feafon of fowing is the fame ; and the clo¬ ver is well eltabliihed in the ground, before it is over¬ topped by the barley. At the fame time, barley com¬ monly is fooner cut than either oats or wheat. In a word, barley is rather a nurfe than a flepmother to clover during its infancy. When clover is fown in fpring upon wheat, the foil, which has lain five or fix months without being Hirred, is an improper bed for it; and the wheat, being in the vigour of. growth, overtops it from the beginning. It cannot be fown along with oats, becaufe of the hazard of frofl; and when fown as ul'ual among the oats three inches high, it is over-topped, and never enjoys free air till the oats be cut. Add, that where oats are fown upon the winter- furrow, the foil is rendered as hard as when under wheat.—Red clover is fometimes fown by itfelf with¬ out other grain: but this method, befide lofing a crop, is not falutary ; becaufe clover in its infant Hate re¬ quires flicker. As to the quantity of grain proper to be fown with clover : In a rich foil well pulverized, a peck of barley on an Englifh acre is all that ought to be ventured ; but there is not much foil in Scotland fo rich. Two Linlithgow firlots make the proper quantity for an acre that produces commonly fix bolls of barley ; half a firlot for what produces nine bolls. To thofe who are governed by cuflom, fo fmall a quantity will be thought ridiculous. Let them only confider, that a rich foil in perfett good order, will from a fingle feed : Part. II.

The yellow- |yellow clo- ribwort, 0f rye-grafs, is the fame in general with that nefs of the ftem is another indication of its ripenefs; ■| wor^and °f red clover. We proceed to their peculiarities. Yel- in which particular it refembles oats, barley, and other rye-grafs. low clover, ribwort, rye-grafs, are all of them early culmiferous plants. The bell manner to manage a crop plants, blooming in the end of April or beginning of of rye-grafs for feed, is to bind it loofely in fmall May. The two latter are evergreens, and therefore fheaves, widening thent at the bottom to make them excellent for winter-pafture. Rye-grafs is lefs hurt by Hand ereA; as is done with oats in moift weather. In froft than any of the clovers, and will thrive in a moi- that Hate they may Hand till fufficiently dry for fter foil: nor in that foil is it much affedted by threlhing. By this method they dry more quickly, drought. In a rich foil, it grows four feet high : even and are' lefs hurt by rain, than by clofe binding and in the dry fummer 1775, it rofe to three feet eight putting the flieaves in fhocks like corn. The worfl: inches; but it had gained that height before the drought came on. Thefe graifes are generally fown with red clover for producing a plentiful crop. The proportion of feed is arbitrary; and there is little danger of too much. When rye-grafs is fown for procuring feed, five firlots wheat-meafure may be fown on an acre; and for procuring feed of ribwort, 40 pounds may be fown. The roots of rye-grafs fpread horizontally : they bind the foil by their number; and tho* fmall, are yet fo vi¬ gorous as to thrive in hard foil. Red clover has a large tap-root, which cannot penetrate any foil but what is open and free ; and the largenefs of the root makes the foil ftill more open and free. Rye-grafs, once a great favourite, appears to be difcarded in moft parts of Bri¬ tain. The common pra&ice has been, to fow it with red clover, and to cut them promifcuoufly the beginning of ufelefs for feed. t r r i th * • rru., — way of all is to fpread the rye-grafs on the moift ground, for it makes the feed malten. The flieaves, when fuffi¬ ciently dry, are carried into clofe carts to where they are to be threfhed on a board, as mentioned above for clover. Put the ftraw in a rick when a hundred {tone or fo are threflied. Carry the threftiing-board to the place where another rick is intended; and fo on till the whole feed be threflied, and the ftraw ricked. There is neceffity for clofe carts to fave the feed, which is apt to drop out in a hot fun; and, as obferved above, a hot fun ought always to be chofen for threfliing. Carry the. feed in facks to the granary or barn, there to be feparated from the hulks by a fanner. Spread the feed thin upon a timber-floor, and turn it once or twice a- day till perfedlly dry. If fuffered to take a heat, it is June for green food, and a little later for hay. This in¬ deed is the proper feafon for cutting red clover, becaufe at that time it begins to flower; but as at that time the feed of the rye-grafs is approaching to maturity, its growth is ftopped for that year, as much as of oats or barley cut after the feed is ripe. Oat? or barley cut green before the feed forms, will afford two other cut- The writers on agriculture reckon fainfoin prefer-Ciil ure of able to clover in many refpe&s: They fay, that it pro- f-unfoiu. duces a larger crop ; that it does not hurt cattle when eaten green; that it makes better hay; that it continues four times longer in the ground; and that it will grow on land that will bear no other crop. Sainfoin has a very long tap-root, which is able to tings'; which is the cafe of rye-grafs, of yellow clover, pierce very hard earth. The roots grow very large; and and of ribwort. By fuch management, all the profit will be drawn that thefe plants can afford. When red clover is intended for feed, the ground ought to be cleared of weeds, were it for no other pur- pofe than that the feed cannot otherwife be preferved pure: what feeds efcape the plough ought to be ta- the larger they are, they penetrate to the greater depth; and hence it may be concluded, that this grafs, when it thrives well, receives a great part of its nouriftiment from below the Jiaple of the foil: of courfe, a deep dry foil is beft for the culture of fainfoin. When plants draw their nourifliment from that part of the foil that ken out by the hand. In England, when a crop of is near the furface, it is not of much confequence feed is intended, the clover is always firft cut for hay. This appears to be done, as in fruit-trees, to check the growth of the wood, in order to encourage the fruit. This pra&ice will not anfwer in Scotland, as the feed would often be too late for ripening. It would do bet¬ ter to eat the clover with fheep till the middle of May, which would allow the feed to ripen. The feed is ripe when, upon rubbing it between the hands, it parts readily from the hulk. Then apply the fcythe, fpread the crop' thin, and turn it carefully. When perfectly dry, take the firft opportunity of a hot day for threfli¬ ing it on boards covered with a coarfe Iheet. Another way lefs fubjedt to, rifle, is to Hack the dry hay, and to threlh it in the end of April. After the firft threfli¬ ing, expofe the hulks to the fun, and threlh them over and over till no feed remain. Nothing is more effica- Vol. I. Part I. whether their number be great or fmall. But the cafe is very different when the plants receive their food, not only near, but alfo deep below, the furface- Befides, plants that Ihoot their roots deep are often fupplied with moifture, when thofe near the furface are parched with drought. To render the plants of fainfoin vigorous, itisnecef- fary that they be fown thin. The beft method of do¬ ing this is by a drill; becaufe, when fown in this man ner, not only the weeds, but alfo the fupernumerary plants, can eafily be removed.' It is feveral years be¬ fore fainfoin comes to its full ftrength ; and the num ber of plants fufficient to ftock a field, while in this im- perfeft ftate, will make but a poor crop for the firft year or two. It is therefore neceffary tnat it be fown in fuch a manner as to make it eafy to take up plants Qjl in 3c6 A G R I C U PraAice. in fuch numbers, and in fuch order, as always to leave v-—-' in the field the proper number in their proper places. This can only be done, with propriety, by fowing the ^plants in rows by a drill. Suppofing a field to be dril¬ led in rows at ten inches diftance, the partitions may be hand-hoed, and the rows drefi'ed in fuch a manner as to leave a proper number of plants. In this fitua- tion the field may remain two years; then one-fourth of the rows may be taken out in pairs, in fuch a man¬ ner as to make the beds of fifty inches, with fix rows in each, and intervals of thirty inches, which may be ploughed. Next year, another fourth of the rows may be taken out in the fame manner, fo as to leave double rows with partitions of ten inches, and intervals of thirty : All of which may be hoed at once or alternately, as it may be found moft conve¬ nient. The great quantity of this grafs which the writers on this fubjeft afiure us may be railed upon an acre, and the excellency and great value of the hay made of it, fhould induce farmers to make a complete trial of it, and even to ufe the fpade in place of the hoe, or hoe- plough, if neceffary. The plants taken up from a field of fainfoin may be fet in another field; and if the tranfplanting of this grafs fucceeds as well as the tranfplanting of lucerne has done with Mr Lunin de Chateauvieux, the trouble and expence will be fufficiently recompenfed by the largenefs of the crops. In tranfplanting, it is necef¬ fary to cut off great part of the long tap-root: this will prevent it from ftriking very deep into the foil, and make it pufh out large roots in a Hoping direction from the cut end of the tap-root. Sainfoin managed in this manner, will thrive even on {hallow land that has a wet bottom, provided it be not overftocked with plants. Whoever inclines, to try the culture of this grafs in Scotland, fiiould take great pains in preparing the land, and making it as free from weeds as poffible. In England, as the roots ftrike deep in that chalky foil, this plant is not liable to be fo much injured by drought as other graffes are, whofe fibres lie horizon¬ tally, and lie near the furface. The quantity of hay produced is greater and better in quality than any other. But there is one advantage attending this guafs, , which renders it fuperior to any other; and that ari- fes from feeding with it milch cows. The prodigious increafe of milk which it makes is aftonifiiing, being nearly double that produced by any other green food. The milk is alfo better, and yields more cream than any other; and the butter procured from it much bet- jgj ter coloured and flavoured. Remarks The following remarks by an Englifli farmer are on the cul- made from much experience and obfervation. foTn in**”1* ^a^nf°in much cultivated in thofe parts where England. t^ie ^ ’s a chalky kind. It will always fucceed well where the roots run deep; the worft foil of all for it is where there is a bed of cold wet clay, which the tender fibres cannot penetrate. This plant will make a greater increafe of produce, by at leaft 30 times, than common grafs or turf on poor land. Where it meets with chalk or Hone, it will extend its roots through the cracks and chinks to a very great depth in fearch of nourifhixient. The drynefs is of more L T U R E. Part II. confequence than the richnefs of land for fainfoin ; al- Pi adHce. though land that is both dry and rich will always pro- -v—"' duce the largeft crops. It is very commonly fowed broadcafl; but it is found to anfwer bell in drills, efpecially if the land be made fine by repeated ploughing, rolling, and harrowing. Much depends on the depth which this feed is fown. If it be buried more than an inch deep, it will feldom grow ; and if left uncovered, it will pulh out its roots above ground, and thefe will be killed by the air. March and the beginning of April are the beft feafons for fowing it, as the feverity of winter and the drought of fummer are equally unfavourable to the young plants. A bufhel of feed fown broadcaft, or half that quantity in drills, if good, is fufficient for an acre. The drills fhould be 30 inches apart, to admit of horfe- hoeing between them. Much, however, depends on the goodnefs of the feed, which may be beft judged of by the following marks. The hulk being of a bright colour, the kernel plump, of a grey or bluifh colour without, and, if cut acrofs, greenifti and frefti withinfide ; if it be thin and furrowed, and of a yeliowifli call, it will feldom grow. When the plants ftand fingle, and have room to fpread, they produce the greateft quantity of herbage, and. the feed ripens beft. But farmers in general, from a miftaken notion of all that appears to be wafte ground being unprofitable, plant them fo clofe, that they choke and impoveriftr each other, and often die" in a few years. Single plants run deepeft and draw moft nou- rifhment; they are alfo eafieft kept free from weeds. A fingle plant will often produce half a pound of hay, when dry. On rich land this plant will yield two good: crops in a year, with a moderate {hare of culture. A, good crop muft not be expefted the firft year ; but, if the plants ftand not too thick, they will increafe in fize the fecond year prodigioufly. No cattle ftiould be turned on the field the firft win¬ ter after the corn is off with which it was fown, as their feet would injure the young plants. Sheep fhould not come on the following fummer, becaufe they would bite off the crown of the plants, and prevent their {hooting again. A fmall quantity of foapers afhes as. a top-dreffing will be of great fervice, if laid on the firft winter. If the fainfoin be cut juft before it comes into bloom, it is adfnirable food for horned cattle ; and if cut thus early, it will yield a fecond crop the fame feafon. But if it proves a wet feafon, it is better to let it ftand till its bloom be perfected; for great care muft be taken, in making it into hay, that the flowers do not drop off, as cows are very fond of them ; and it requires more time than other hay in drying. Sain¬ foin is fo excellent a fodder for horfes, that they require no oats while they eat it, although they be worked hard all the time. Sheep will alfo be fattened with it fafter than with any other food.. If the whole feafon for cutting proves very rainy, it is better to let the crop ftand for feed, as that will amply repay the lofs of the hay; becaufe it will not only fetch a good price,, but a peck of it . will go as far as a peck and a half of oats for horfes.

Seeded fainfoin fliould always be cut in a morning or evening, when the dews render the ftalks tender. If cut when the fun fhines hot, much of the feed will fall out and be loft. An acre of very ordinary land, when improved by this grafs, will maintain four cows very well from the firft of April to the end of November; and afford, be- fides, a fufficient ftore of hay to make the greater part of their food the four months following. If the foil be tolerably good, a field of fainfoin will laft from 15 to 20 years in prime; but at the end of feven or eight years, it will be neceffary to lay on a moderate coat of well-rotted dung; or, if the foil be very light and fandy, of marie. By this means the future crops, and the duration of the plants in health and vigour, will be greatly increaled and prolonged. Hence it will appear, that for poor land there is no¬ thing equal to this grafs in poin't of advantage to the farmer. Clover will laft only two years in perfe&ion; and often, if the foil be cold and moift, near half the plants will rot, and bald patches be found in every part of the field the fecond year. Befides, from our frequent rains during the month of September, many crops left for feeding are loft. But from the quantity and excellent quality of this grafs (fainfoin), and its ripen¬ ing earlier, and continuing in vigour fo much longer, much rifk and certain expence is avoided, and a large annual profit accrues to the farmer. Culture of The writers on agriculture, ancient as well as mo- Juceme. dern, beftow the higheft encomiums upon lucerne as affording excellent hay, and producing very large crops. Lucerne remains at leaft x o or 12 years in the ground, and produces about eight tons of hay upon the Scots acre. Thereisbutlittle ofitcultivatedinScotland. How¬ ever, it has been tried in feveral parts of that country; and it is found, that, when the feed is good, it comes up very well, and Hands the winter froft. But the chief thing which prevents this grafs from being more ufed in Scotland, is the difficulty of keeping the foil open and free from weeds. In a few years the furface becomes fo hard, and the turf fo ftrong, that it de- ftroys the lucerne before the plants have arrived at their greateft perfection : fo that lucerne can fcarce be cultivated with fuccefs there, unlefs fome method be fallen upon of deftroying the natural grafs, and pre¬ vent the furface from becoming hard and impenetrable. This cannot be done effectually by any other means than horfe-hoeing. This method was firft propofed by Mr Tull, and afterwards praftifed fuccefsfully by M. de Chateauvieux near Geneva. It may be of ufe therefore to give a view of that gentleman’s method of cultivating lucerne. He does not mention any thing particular as to the manner of preparing the land; but only obferves in ge¬ neral, that no pains fliould be fpared in preparing it. He tried the fowing of lucerne both in rows upon the beds where it was intended to ftand, and likewife the fowing it in a nurfery, and afterwards tranfplanting it into the beds prepared for it. He prefers tranfplant¬ ing ; becaufe, when tranfplanted., part of the tap-root L T U R E. 307 is cut off, and the plant (hoots out a number oflateral Pradticc. ^ branches from the cut part of the root, which makes it y ’ fpread its roots nearer the furface, and confequently renders it more eafily cultivated : befides, this circum- ftance adapts it to a (hallow foil, in which, if left in its natural ftate, it would not grow. The tranfplanting of lucerne is attended with many advantages., The land may be prepared in the fummcr for receiving the plants from the nurfery in autumn ; by which means the field muft be in a much better fi- tuation than if the feed had been fown upon it in the fpring. By tranfplanting, the rows can be made more regular, and the intended diftances more exaftly ob- ferved; and confequently the hoeing can be performed more perfedtly, and with lefs expence. Mr Chateau¬ vieux likewife tried the lucerne in Angle beds three feet wide, with (ingle rows ; in beds three feet nine inches wide, with double rows; and in beds four feet three inches wide, with triple rows. The plants in the Angle rows were fix inches afunder, and thofe in the double and triple rows were about eight or nine inches. In a courfe of three years he found, that a fingle row produced more than a triple row of the fame length. The plants of lucerne, when cul¬ tivated by tranfplantation, ftiould be at leaft fix in¬ ches afunder, to allow them room for extending their crowns. He further obferves, that the beds or ridges ought to be raifed in the middle ; that a fmall trench, two or three inches deep, ftiould be drawn in the middle; and that the plants ought to be fet in this trench, covered with earth up to the neck. He fays, that if the lu¬ cerne be fown in fpring, and in a warm foil, it will be ready for tranfplanting in September; that, if the wea¬ ther be too hot and dry, the tranfplanting fliould be delayed till Oftober; and that, if the weather be un¬ favourable during both thefe months, this operation muft be delayed till fpring. He further direfts, that the plants fliould be carefully taken out of the nurfery* fo as not to damage the roots; that the roots be left only about fix or feven inches long ; that the green crops be cut off within about two inches of the crown ; that they be put into water as foon as taken up, there to remain till they are planted ; and that they fliould be planted with a planting-ftick, in the fame manner as cabbages. He does not give particular dire&ions as to the times of horfe-hoeing; but only fays in general, that the in¬ tervals fliould be ftirred once in the month during the whole time that the lucerne is in a growing ftate. He likewife obferves, that great care ought to be taken not to fuffer any weeds to grow among the plants, at leaft for the firft two or three years ; and for this purppfe, that the rows, as well as the edges of the intervals where the plough cannot go, ftiould be weeded by the hand. _ „ Burnet is peculiarly adapted to poor land; be- cu]ture 0f fides, it proves an excellent winter-pafture when hardly burnet. any thing elfe vegetates. Other advantages are, It makes good butter; it never blows or fwells cattle ; it is fine pafture for (heep ; and will flourifti well on poor, light, fandy, or ftony foils, or even on dry chalk hills. The cultivation of it is neither hazardous nor expen Qjj z five. So8 A G R I C U Pradtice. five. If the land is prepared as is generally done for turnips, there is no danger of its failing. After the firft year, it will be attended with very little expence, as the flat circular fpread of its leaves will keep down, or prevent the growth of weeds. On the failure of turnips, either from the fly or the black worm, fome of our farmers have fown the land with burnet, and in March following had a fine pafture for their fheep and lambs. It will perfect its feed twice in a fummer; and this feed is faid to be as good as oats for horfes ; but it is too valuable to be applied to that ufe. It is fometimes fown late in the fpring with oats and barley, and fucceeds very well; but it is beft to fow it fingly in the beginning of July, when there is a pro- fpe£l of rain, on a fmall piece of land, and in O&ober following, tranfplant it in rows two feet apart, and a- bout a foot diftant in the rows. This is a proper dif- tance, and gives opportunity for hoeing the intervals in the fucceeding fpring and fummer. After it is fed down with cattle, it fhould be har¬ rowed clean. Some horfes will not eat it freely at fir ft, but in two or three days they are generally very fond of it. It affords rich pleafaht milk, and in great plenty. A gentlemen farmer near Maidftone fome years fince fowed four acres as foon as the crop of oats were got off, which was the latter end of Auguft. He threw in i 2 pounds of feed per acre, broadcaft; and no rain falling until the middle of September, the plants did not appear Before the latter end" of that month. There was however a good crop, and in the fpring he fit the plants out with a turnip-hoe, leaving them about a foot diftant from each other. But the drill method is preferable, as it faves more than half the feed. The land was, a poor dry gravel, not worth three ihillings an acre for any thing elfe. The fevereft froft never injures this plant; and the oftener it is fed the thicker are its leaves, which fpring conftantly from its root. Sect.V. Rotation of Crops. 185 No branch of huibandry requires more IkiH and fa- gacity than a proper rotation of crops, fo as to keep the ground always in heart, and yet to draw out of it the greateft profit poffible. Some plants rob the foil, others are gentle to it: fome bind, others loofen. The nice point is, to intermix crops, fo as to make the greateft profit confiftently with keeping the ground in trim. In that view, the nature of the plants employ¬ ed in hufbandry muft be accurately examined. Oulmifo The difference between culmiferous and leguminous rous and le- plants, is occafionally mentioned above*. With re- guminous fpe& to the prefent fubjedl, a clofer infpe&ion is necef- j lants. fary. Culmiferous-plants, having fmall leaves and few * N° i2o, in number, depend moftly on the foil for nouriftiment, and little on the air. During the ripening of the feed, they draw probably their whole nourifhment from the foil; as the leaves by this time, being dry and wither¬ ed, muft have loft their power of drawing nouriftiment from the air. Now, as culmifercus plants are chiefly cultivated for their feed, and are not cut down till the feed be fully ripe, they may be pronounced all of them to be robbers, fome more, fome lefs. But fuch plants, while young, are all leaves; and in that ftate draw. L T U R E. Part IE moft of their nourifhment from the air. Hence it is, Pradtice. that where cut green for food to cattle, a culmiferous crop is far from being a robber. A hay-crop accor¬ dingly, even where it confifts moftly of rye-grafs, is not a robber, provided it be cut before the feed is formed; which at any rate it ought to be, if one would have hay in perfection. And the foggage, excluding the froft by covering the ground, keeps the roots warm. A leguminous plant, by its broad leaves, draws much of its nouriftiment from the air. A cabbage, which has very broad leaves, and a multitude of them, owes its growth more to the air than to the foil. One fact is certain, that a cabbage cut and hung up in a damp place, preferves its verdure longer than other plants. At the fame time,; a feed is that part of a plant which requires the moft nourifhment; and for that nourifh¬ ment a culmiferous plant muft be indebted entirely to the foil. A leguminous crop, on the contrary, when cut green for food, muft be very gentle to the ground. Peafe and beans are leguminous plants ; but being cul¬ tivated for feed, they feem to occupy a middle ftation : . their feed makes them more fevere than other legumi¬ nous crops cut green ; their leaves, which grow till reaping, make them lefs fevere than a culmiferous plant left to ripen. Thefe plants are diftinguifhed no lefs remarkably by the following circumftance. All the feeds of a culmife¬ rous plant ripen at the fame time. As foon as they begin to form, the plant becomes ftationary, the leaves wither, the roots ceafe to pufh, and the plant when cut down is blanched and faplefs. The feeds of a leguminous plant are formed fucceftively : flowers and fruit appear at the fame time in different parts of the plant. This plant accordingly is continually growing, and pufhing its roots. Hence the value of bean or peafe ftraw above that of wheat or oats: the latter is withered and dry when the crop is cut; the former, green and fucculent. The difference therefore, with refpedl to the foil, be¬ tween a culmiferous and leguminous crop, is great. The latter, growing till cut down, keeps the ground in con- ftant motion, and leaves it to the plough loofe and mel¬ low. The former gives over growing long before reap¬ ing ; and the ground, by want of motion, turns com- paft and hard. Nor is this all. Dew falling on a culmiferous crop after the ground begins to harden, refts on the furface, and is lucked up by the next fun. Dew that falls on a leguminous crop, is lhaded from the fun by the broad leaves, and finks at leifure into the ground. The ground accordingly, after a culmi-. ferous crop, is not only hard, but dry : after a legu¬ minous crop, it is not only loofe, but foft and unc-. /tuous. Of all culmiferous plants, wheat is the moft fevere,. by the long time it occupies the ground without ad¬ mitting a plough. And as the grain is heavier'than that of barley or oats, it probably requires more nou-. rilhment than either. It is, obferved above, that as peafe and beans draw part of their nouriftiment from the air, by their green leaves while allowed to Hand, they draw the lefs from the ground ; and by their con- ftant growing they leave it in good condition for fub- fequent crops. In both refpefts they are preferable to any culmiferous crop. Culmiferous crops, as obferved above, are not rob¬ bers when cut green ; the foil, far from hardening, is , jrtir. A G II I C raftice. kept in conilant motion by the pufhing of the roots, J and is left more tender than if it had been left at reft without any bearing crop. Bulbous-rooted plants are above all fuecefsful in di¬ viding and pulverizing the foil. Potato-roots grow fix, eight, or ten inches under the furface ; and, by their fize and number, they divide and pulverize the foil better than can be done by the plough; confequent- Jy, whatever be the natural colour of the foil, it is black when a potato-crop is taken up. The potato, however, with refpeft to its quality of dividing the foil, muft yield to a carrot or parfnip ; which are large roots, and pierce often to the depth of 18 inches. The turnip, by its tap-root, divides' the foil more than can be done by a fibrous-rooted plant; but as its bul¬ bous root grows moftly above ground, it divides the foil lefs than the potato, the carrot, or the parfnip. Red clover, in that refpeft, may be put in the fame clafs with turnip. Whether, potatoes or turnip be the more gentle crop, appears a puzzling queftion. The former bears feed, and probably draws more nourifhment from the foil than the latter, when cut green. On the other hand, potatoes divide the foil more than turnip, and leave it more loofe and friable. It appears no lefs puzzling, to determine between cabbage and turnip : the former draws more of its nourifhment from the air, the latter leaves the foil more free and open. The refult of the whole is what follows: Culmi- ferous plants are robbers ; fome more, fome lefs : they at the fame time bind the foil; fome more, fome lefs. Leguminous plants in both refpefts are oppofite : if any of them rob the foil, it is in a very flight degree; and all of them without exception loofen the foil. A culmiferous crop, however, is generally the more pro¬ fitable : but few foils can long bear the burden of fuch crops, unlefs relieved by interjected leguminous crops. Thefe, on the other hand, without a mixture of cul¬ miferous crops, would foon render the foil too loofe. Thefe preliminaries will carry the farmer fome length in directing a proper rotation of crops. Where dung, lime, or other manure, can be procured in plenty to recruit the foil after fevere cropping, no rotation is more proper or profitable m a ftrong foil, than wheat, peafe or beans, barley, oats, fallow.. The whole farm may be brought under this rotation, except fo far as hay is wanted. But as fuch command of manure is rare, it is of more importance to determine what fhould be the rotation when no manure can be procured but the dung colle&ed in the farm. Confidering that cul¬ miferous crops are the more profitable in rich land, it would be proper to make them more frequent than the other kind. But as there are few foils in Scotland that ; will admit fuch frequent culmiferous crops without fuf- fering, it may be laid down as a general rule, that al¬ ternate crops, culmiferous and leguminous, ought to form the rotation. Nor are there many foils that will Hand good, even with this favourable rotation, un¬ lefs relieved from time to time by pafturing a few years. If fuch extended rotation be artfully carried on, crops without end may be obtained in a tolerable good foil, without any manure but what is produced in the farm. It is fcarce neceffary to be mentioned, being known to every farmer that clay anfwers belt for. wheat, U L T U R E. 309 moift clay for beans, loam for barley and peafe, light Prafiice. foil for turnip, fandy foil for rye and buck-wheat; and " that oats thrive better in coarfe foil than any other The. nature grain. Now, in directing a rotation, it is not fuffi-of foil con- dent that a culmiferous crop be always fucceeded by a fdered, leguminous: attention muft alfo be given, that no crop be introduced that is unfit for the foil. Wheat, being rotation of a great binder, requires more than any other crop a crops.. leguminous crop to follow. But every fuch crop is not proper: potatoes are the greateft openers of foil; but they are improper in a wheat foil. Neither will tur¬ nip anfwer, becaufe.it requires a light foil. A very loofe foil, after a crop of rye, requires rye-grafs to bind it, or the treading of cattle in pafturing: but to bind the foil, wheat muft not be ventured; for it fucceeds ill in loofe foil. Another confideration of moment in dire&ing the rotation, is to avoid crops that encourage weeds. Peafe is the fitteft of all crops for fucceeding to wheat, be- caufe it renders the ground loofe and mellow, and the fame foil agrees with both. But beware of peafe, un¬ lefs the foil be left by the wheat perfe&ly free of weeds; becaufe peafe, if not an extraordinary crop, fofter weeds. Barley may be ventured after wheat, if the farmer be unwilling to lofe a crop. It is indeed a rob¬ ber; better, however, any crop, than run the hazard of poifoning the foil with weeds. But to prevent the ne- ceffity of barley after wheat, the land ought to be fal¬ lowed before the wheat: it cleans the ground tho¬ roughly, and makes peafe a fecure crop after wheat. And after a good crop of peafe, barely never fails. A horfe-hoed crop of turnip is equal to a fallow for root¬ ing out weeds ; but turnip does not fuit land that is proper for wheat. Cabbage does well in wheat foil; and a horfe-hoed crop of cabbage, which eradicates weeds, is a good preparation for wheat to be fucceed¬ ed by peafe; and a crop of beans diligently hand- hoed, is in that view little inferior;.. As red clover re- ■ quires the ground to be perfeftly clean, a good crop • of it enfures wheat; and next peafe. . In loam, a drill- - ed crop of turnip or potatoes prepares the ground, e- - qual to a fallow., for the fame fuecellion; Another rule is, to avoid a frequent repetition of the fame fpecies; for to produce good crops, change of fpecies is no lefs neceflary than change of feed. The fame fpecres returning every fecond or third year, will infallibly degenerate, and be a fcanty crop. This is remarkably the cafe of red clover. Nor will our - fields bear pleafantly perpetual crops of wheat after fallow, which is the practice of fome Englifh farmers. , Hitherto of rotation in the fame field.

Pafture-grafs, while young, maintains many animals; and the field is greatly recruited by what they drop ; it is even recruited by hay crops, provided the grafs be cut before feeding. But as old grafs yields little pro¬ fit, the field ought to be taken up for corn when the pafture begins to fail; and after a few crops, it ought Rotation in a free foil. r> *775- 1. Turnip. 2.

Some farmers are of opinion, that wheat ought to be cut before it is fully ripe. Their reafons. are, firft, that ripe wheat is apt to fhakeand next, that the flour is not fo good. With refpe Wheat, and fuch grain as is fown before winter, requires hoeing more than oats, barley, or other grain fown in the fpring ; for, if the land has. been well ploughed before the fowing of fpring-corn, it neither has time to harden, nor to produce many weeds, not having been expofed to the winter’s fnow and rain.

In the common method, as there are many more plants than can find fufficient nourifhment, and as it is impoffible to affift them by hoeing, numbers die before they attain maturity, the greateft part remain fickly and drooping ; and thus part of the feed is loft. On the contrary, in the new method, all the plants have as much food as they require-; and as they are, from time to time, affifted by hoeing, they become fo vigo¬ rous as to equal in their production the numerous but fickly plants cultivated in the common method. Of Hoeing. The new hulbandry is abfolutely impra&icable in lands that are not eafily ploughed. Attempting to cultivate land according to this hulbandry, without at¬ tending to this circumftance, that it is practicable in no land excepting fuch as have already been brought ' into good tilth by the old method, has gone far to zzo make it contemptible in many places. The diffe- When a field is in good tilth, it fhould be fown fo rent hoe- ^Jn a3 to leave fufficient room for the plants to extend ln^S’ their roots. After being well ploughed and harrowed, it muft" be divided into'rows, at the diftance of thirty inches from one another. On the fidesof each of thefe rows, two rows of wheat muft be fowed fix inches di- ftant from each other. By this means there will be an- interval of two feet wide betwixt the rows, and every plant will have room enough to extend its roots, and to fupply it vvith food. The intervals will likewife be fuf¬ ficient for allowing the earth to be hoed or tilled with¬ out injuring the plants in the rows., The firft hoeing, which ffiould be given before the winter, is intended to drain away the wet, and to dif- pofe the earth to be mellowed by the frofts. Thefe two ends will be anfwered by drawing two fmall fur¬ rows at a little diftance from the rows, and throwing the earth taken from the furrows into the middle of the intervals. This firft hoeing (hould be given when the wheat is in leaf. The fecond hoeing, which is intended to make the- plants branch, ffiould be given after the hard frofts are over. To do this with advantage, after ftirring the earth a little near the rows, the earth which was thrown in the middle of the intervals ffiould be turned back in¬ to the furrows. This earth, having been mellowed by the winter, fupplies the plants with excellent food, and . makes the roots extend. The third hoeing, which is intended to invigorate the ftalk, ffiould be given when the ears of the corn begin to ffiow themfelves. This hoeing may, however, be very flight. But the laft hoeing is of the greateft importance, as it enlarges the grain, and makes the ears fill at their extremities. This hoeing ffiould be given when the wheat is in bloom ; a furrow muft be drawn in the middle of the interval, and the earth thrown to the right and left on the fftot of the plants. This fupports the plants, prevents them from being laid, and pre- L T U R E. 317 pares the ground for the next flowing, as the feed is Practice, then to be put in the middle of the ground that form- ^ 1 ed the intervals. The beft feafon for hoeing is two or three days af¬ ter rain, or fo foon after rain as the foil will quit the inftrument in hoeing. Light dry foils may be hoed al- moft any time, but this is far from being the cafe with ftrong clay foils; the feafon for hoeing fuch is fre¬ quently ffiort and precarious ; every opportunity there¬ fore ,ffiould be carefully watched, and eagerly embra¬ ced. The two extremes of wet and dry, are great ene¬ mies to vegetation in ftrong clay foils. There is a pe¬ riod between the time of clay foils running together, fo as to puddle by Superfluous wet, and the time of their caking by drought, that they are as tra£lable_as need be. This is the junfture for hoeing; and fo much land as ffiall be thus-feafonably hoed, will not cake or cruft upon the furface, as it otherwife would have done, till it has been foaked or drenched again with rain ; in which cafe the hoeing is to be repeated as foon as the foil will quit the inftrument, and as of¬ ten as neceffary; by which time the growing crop will begin to cover the ground, fo as to aft as a fcreen to the furface of the land againft the intenfe heat of the fun, and thereby prevent, in great meafure, the bad effefts of the foil’s caking in dry weather. By this fucceffive tillage, or hoeing, good crops will- be obtained, provided the weather is not very unfa¬ vourable. But as ftrong, vigorous plants are longer before they, arrive at maturity, corn raifed in the new way is later in ripening than any other, and muft therefore be flown earlier. In order to prepare the intervals for flowing again,, fome well-rooted dung may be laid in the deep furrows made in the middle of the intervals ; and this dung muft be covered with the earth that was before thrown towards the rows-of wheat. But, if the land does not require mending, the deep furrow is filled without any dung. This operation ffiould be performed immedi¬ ately after harveft, that there may be time to give the land a flight ftirring before the rows are fowed; which ffiould occupy the middle of the fpace which formed the intervals during the laft crop. The intervals of the fecond year take up the fpace occupied by the ftubble of the firft. Suppofing dung to -be neceffary, which is denied by- many, a very fmall quantity is fufficient; a Angle layer, , put in the bottom of each furrow, will be enough. Description of the Instruments commonly ufed ini the New Husbandry. ^ 221 Fig. 1. is a marking plough. The principal ufe ofinftruments- this plough is to ftraight and regulate the ridges. The defcribed.- firft line is traced by the eye, by means of three poles,plate VII->r placed in a ftraight line. The plough draws the firft furrow in the direftion of this line ; and, at the fame time, with the tooth A, fixed in the block of wood near the end of the crofs-pole or Aider B B, marks the breadth of the ridge at the diftance intended. The ploughman next traces the fecond line or rutt made by the tooth, and draws a fmall furrow along it; and con¬ tinues in this manner till the whole field is laid out in ftraight and equidiftant ridges. Figv- 3i 8 A G R I C Practice. Fig. 2. is a plough for breaking up lee, or turning Up the bottom of land when greatly exhaufted. By its conftruftion, the width and depth of the furrows can Plate VII. be regulated to a greater certainty than by any other hitherto known in this country. Its appearance is heavy ; but two horfes are fufficient to plough with it in ordinary free land; and only four are neceffary in the ftiffeft clay-foils. This plough is likewife eafily held and tempered. A, is the fword fixed fh the fixers B, which runs thro’ a mortoife E, at the end of the beam C, and regulates the depth of the furrow by railing or depreffing the beam ; it is fixed by putting the pin D thro’ the beam and fword, and is moveable at E. Fig. 3. is a jointed brake-harrow with 24. teeth, fha- ped like coulters, and Handing at about an angle of 80 degrees. By this inflrument the land is finely pulve¬ rized, and-prepared for receiving the feed from the drill. It requires four horfes in HifF, and two in open, land. This harrow is likewife ufed for levelling the ridges; which is done by preffing it down by the handles where the ridge is high, and railing it up when low. Fig. 4. is an angular weeding harrow, which may follow the brake when necefiary. The feven hindmolt teeth fhould Hand at a more acute angle than the reft, in order to colledt the weeds, which the holder can drop at pleafure, by railing the hinder part, which is fixed to the body of the harrow by two joints. Fig. 5. is a pair of harrows with drafts. This har¬ row is ufed for covering the feed in the drills, the horfe going in the furrow. Fig. 6. is a drill-plough, conftrucled in fuch a man¬ ner as to fow at once two rows of beans, peafe, or wheat. This machine is eafily wrought by two horfes. A, is the happer for containing the feed ; B, circular boxes forTeceiving the feed from the happer; CC, two fquare boxes which receive the feed from fmall holes in the circular boxes, as they turn round ; and laft of all, the feed is dropped into the drills through holes in the fquare boxes, behind the coulters D. The cylinder E follows, which, together with the wheel F, regulates the depth of the coulters, and covers the feed; the har¬ row G comes behind all, and covers the feed more completely. Id H, two Aiders, which, when drawn out, prevent the feed from falling into the boxes ; and, I, is a ketch which holds the rungs, and prevents the boxes from turning, and lofing feed at the ends of the ridges.

This inftrument, which is chiefly calculated for fmall inclofures of light grounds, is a fort of ftrong plough rake, with four large teeth at a, a, b, b, a little incurvated. The diftance from a to a, and from b to b, is nine inches. The interval between the two inner teeth, a and b, is three feet fix in¬ ches, which allows fuf&cient room for the hole-plough to move in. To the piece of timber cc, forming the head of the rake, are fixed the handles d, and the beam e, to which the horfe is farmed. When this inftrument is drawn over a piece of land made thoroughly fine, 2 J L T U R E.

When the ground is thus formed into drills, the peafe may be fcattered by a fingle motion of the hand at a cer¬ tain diftance from one another into the channels, and then covered with the flat part of a hand-rake, and prefied down gently. This inftrument is fo fimple, that -any workman may eafily make or repair it.

Thefe machines, (with five coulters fixteen guineas, with four coulters fifteen guineas) equally excel in fet- ting or planting all forts of grain and feeds, even carrot feed,' to exaiftnefs, after the rate of from eight to ten chain acres per day, with one man, a boy, and two horfes. They depofite the grain or feed in any given quantity from one peck to three bufhels per acre, re¬ gularly and uniformly, and that without grinding or bruifing the feed, and at any given depth, from half an inch to half a dozen inches, in rows at the diftance of twelve.

But Drufus dying fuddenly, all thofe who had been much about him were commanded by Tibe¬ rius to withdraw from Rome, left the fight and pre¬ fence of them ihould renew his affliction. Agrippa, who had indulged bis inclination to liberality, was ob¬ liged to leave Rome overwhelmed with debts, and in a very poor condition. He did not think it fit to go to Jerufalem, becaufe he was not able to make a figui about the feaft of the paffover, in the year of JefusChrift 44, St James major, the fon of Zebedee and brother to St John the Evangelift, was feized by, his order and put to death. He proceeded alfo to lay hands on Sj: Peter, and imprifoned him, waiting till the feftival was over, that he might then have him executed.' But God having miraculoufly delivered St Peter from the place of his confinement, the defigns of Agrippa were fruftrated. After the paflbver, this prince went from. there fuitable to his birth. He retired therefore to Jerufalem to Ccefarea, and there had games performed a1' --l— ,-1 ■ in honour of Claudius. Here the inhabitants of Tyre and Sidon waited on him to fue for peace. Agrippa being come early in the morning to the theatre, with a defign to give them audience, feated himfelf on his throne, drefted in a robe of filver-tiffue, worked in the moft admirable manner. The rifing fun darted on it " ith its rays, and gave it fuch a luftre as the eyes of the caftle of Malfada, where he lived rather like a pri¬ vate perfon than a prince. Herod the Tetrarch, his uncle, who had married Herodias his fifter, affifted him for fome time with great generofity. He made him principal magiftrate of Tiberias, and prefented him with a large fum of money: but all this was not fuffi- cient to anfwer the exceffive expences and profufion of Agrippa ; fo that Herod growing weary of. afiifting the fpeCtators could not endure. When therefore the him, and reproaching him with his bad oeconomy. A- grippa took a refolution to quit Judea and return to Rome. Upon his arrival, he was received into the good graces of Tiberius, and commanded to attend Tiberius Nero the fon of Drufus. Agrippa, however, "having more inclination for Caius the Ton of Germani- cus, and grandfon of Antonia, chofe rather to attach himfelf to him ; as if he had fome prophetic views of the future elevation of Caius, who at that time was be¬ loved by all the world. The great affiduity and agree¬ able behaviour of Agrippa fo far engaged this prince, that he kept him continually about him. Agrippa being one day overheard by Eutyches, a have whom he had made free, to exprefs his wifiies for Tiberius’s death and the advancement of Caius, the Have betrayed him to the Emperor; whereupon A- grippa was loaded with fetters, and committed to the cuftody of an officer. Tiberius foon after dying, and Caius Caligula fucceeding him, the new Emperor heaped many favours and much wealth upon Agrippa; changed his iron fetters into a chain of gold; fet a royal diadem upon his head ; and gave him the tetrar- chy which Philip, the fon of Plerod the Great, had been poffeffed of, that is, Batanssa and Trachonitis. To this he added that of Lyfanias ; and Agrippa re¬ turned very foon into Judea to take poffeffion of his new kingdom. Caius being foon after killed, Agrippa, who was then at Rome, contributed much by his advice to maintain Claudius in poffeffion of the imperial dignity, to which he had been advanced by the army. But in this affair Agrippa a<5led a part wherein he ffiowed more cunning and addrefs than fincerity and honefty for while he made a ftiow of being in the intereft of du£ts, &c. king fpoke to the Tyrians and Sidonians, the parafites around him began to fay, that it was the voice of a god, and not that of a man. Inftead of rejefting thefe impious flatteries, Agrippa received them with an air of complacency; but at the fame time obferved an owl above him on a cord.' He had feen the fame bird before when he was in bonds by order of Tiberius; and it was then told him, that he fliould be foon fet at liberty: but that whenever he faw the fame thing a fecond time, he ftiould not live above five days after¬ wards. He was therefore extremely terrified; and he died at the end of five days, racked with tormenting pains in his bowels, and devoured with worms. Such was the death of Herod Agrippa, after a reign of feven years, in the year of Chrift 44. Agrippa II. Jon of the preceding Herod, was made king of Chaicide; but three or four years after, he was deprived of that kingdom by Claudius, who gave him in the place of it other provinces. In the war Vef- pafian carried on againft the Jews, Herod fent him a fuccour of 2000 men; by which it appears, that, tho’ a Jew by religion, he was yet entirely devoted to the Ro¬ mans, whofe affiftance indeed he wanted, to fecure the peace of his own kingdom. He lived to the third year of Trajan, and died at Rome A. C. 100. He was the feventh and laft king of the family of Herod the Great. It was before him and Berenice his fifter, that St Paul pleaded his caufe at Caefarea. Agrippa (Marcus Vefpanius), fon-in-law to Augu- ftus, of mean birth, but one of the moft confiderable generals among the Romans. Auguftus’s victory over Pompey and Mark Anthony was owing to his counfel: he adorned the city with the pantheon, baths, aque- the fenate, he fecretly advifed Claudius to be refolute, and not to abandon his good fortune. The Emperor, as an acknowledgment for his kind offices, gave him all Judea and the kindom of Chalcis, which had been Agrippa (Cornelius), born at Cologne in i486, a man of confiderable learning, and by common report a great magician ; for the monks at that time fufpefted every thing of herefy or forcery which they did not un- poffeffed by Herod his brother.

God, being provoked by the fins of jefture that Agur, as well as Lemuel (in chap. xxxi. 1.) Ahab, fent the prophet Elijah to him (1 Kings xvii. were wife men who lived in the time of Solomon,- and 1, /ef.) who declared to him, that there would be a were his interlocutors in the book of Proverbs; an opi- famine of three years continuance. The dearth having nion which F. Calmet thinks is without the leaft fhew lafted three years, the prophet defired Ahab to gather of probability, this book being nothing like a dia- all the people to mount Carmel, and with them the logue. This laft expofitor thinks it probable, that prophets of Baal: when they were thus affembled, Agur was an infpired author different from Solomon, Elijah caufed fire to defeend from heaven upon his fa- whofe fentences it was thought fit to join with thofe of crifice, after which he obtained of God that it ftiould. this prince, becaufe of the conformity of their mat- rain; and then the earth recovered its former fertility, ter. Six years after this, Ben-hadad king of Syria (chap, 2 AHA [ 331 ] AHA xx.) laid fiege to Jerufalem. But God, provoked at this proud Syrian, fent a prophet to Ahab, not only to affure him of victory, but to inftruft him likewife in what manner he was to obtain it. Ahab was order¬ ed to review the princes of the provinces, which he found to be a choice company confifting of 232 young men, who were to command the people in Samaria, •amounting to about 7000 men : with this fmall army Ahab was direfted to fall upon the great hoft of the •Syrians, and that at noon-day, while Ben-hadad and the 3 2 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 deixgns were : but the young men, followed by this fmall army, ad¬ vanced, and killing all that oppofed them, fuch a pa¬ nic feized the Syrian troops, that they began to fly; and even Ben-hadad himfelf mounted his horfe and fled with his cavalry ; which Ahab perceiving, purfued them, killed great numbers of them, and took a con- fiderable booty. After this the prophet came to Ahab, to animate him with frefh courage, and to caution him to keep upon his guard ; affuring him, that Ben-hadad would return againft him the year following. Ac¬ cording to this prediction, at the end of the year he returned and encamped at Aphek, with a refolution to give the Ifraelites battle. Both-armies being ranged in order of battle for feven days fucceffively, at length, upon the feventh day, a battle enfued, wherein the If¬ raelites killed 100,000 of the Syrians, and the reft fled to Aphek; but as they were preffing to get into the city, the walls of Aphek fell upon them and killed 27,000 more. Ben-hadad throwing himfelf upon the mercy of Ahab, this prince received him into his own chariot, and made an alliance with him. The. year following, Ahab defiring to make a kitchen-garden near his palace (chap, xxi.), requefted of one Naboth, a citizen of Jezreel, that he would fell him his vineyard, becaufe it lay convenient for him. But being refufed, he returned in great difcontentment to his houfe, threw himfelf upon the bed, turned towards the wall, and would eat nothing. Jezebel his wife coming in, aflced the reafon of his great concern ; of which being informed, (he procured the death of Naboth, and Ahab took pofleffion of his vineyard. As he returnedfrom Jez¬ reel to Samaria, the prophet Elijah met him, and faid, “ Haft thou killed and alfo taken pofleffion ? Now faith the Lord, In the place where dogs licked up the blood of Naboth, fhall dogs lick thy blood, even thine. As for Jezebel, of her the Lord fpake, faying, The dogs lhall eat Jezebel by the way of Jezreel.” Ahab, hear¬ ing thefe and other denunciations, rent his clothes, put fackcloth upon his.flelh, and gave other indications of his forrow and repentance. But his repentance was neither fmcere nor perfevering. Two years after thefe things, Jeholhaphat king of Judah came to Samaria to vifit Ahab (chap, xxii.) at a time' when he was preparing to attack Ramoth-gilead, which Ben-hadad king of Syria unjuftly with-held from him. The king of Ifrael invited Jehoftiaphat to accompany him in this expedition; which that prince agreed to do, but defired that fome prophet might firft be confulted. Ahabthereforeaffembled the prophets of Baal, in number about 400 ; who all concurred in exhorting the king to march refolutely againft Ramoth-gilead. But Micaiah being alfo confulted, at Jehofhaphat’sfuggeftion,prophe- fied the ruin of Ahab. Upon this, Ahab gave orders to his people to feize Micaiah, and to carry him to Amon the governor of the city, and to Joafh the king’s fon ; telling them in his name,. “ Put this fellow in prifon, and feed him with the bread of affli&ion, and with the water of afflidlion, until I come in peace.” But Mi¬ caiah faid, “ If thou return at all in peace, the Lord hath not fpoken by me.” Ahab therefore and Jehoftia¬ phat marched up to Ramoth-gilead ; and the king of Ifrael faid unto Jehofhaphat, “ I will difguife myfelf,and enter into the battle, but put thou on thy robes :” for he knew that the king of Syria had commanded two and thirty captains that had rule over his chariots, faying, “ Fight neither with fmall nor with great, fave only with the king of Ifrael.” Thefe officers therefore having obferved that Jehoftiaphat was dreffed in royal robes, took him for the king of Ifrael, and fell upon him with great impetuofity : but this prince feeing himfelf prefled fo clofely, cried out; and the miftake being difcovered, the captains of the king of Syria gave over purfuing him. But one of the Syrian army ftiot a random arrow, which pierced the heart of Ahab. The battle lafted the whole day, and Ahab continued in his chariot with his face turned towards the Syrians. la the mean time, his blood was ftill ifiuing from his wound, and falling in his chariot; and towards the evening he died : whereupon proclamation was made by found of trumpet, that every man ffiould return to his own city and country. The king of Ifrael being dead, was carried to Samaria and buried : but his cha¬ riot and the reins of his horfes were walked in the fifti- pool of Samaria, and the dogs licked his blood, ac¬ cording to the word of the prophet. Such being the end of Ahab ; his fon Ahaziah fucceeded him, in the year of the world 3107. AHjETULA, the trivial name of a fpecies of the coluber. See Coluber.

One of his fons he confecrated, by making him pafs through and pe- rifh by the fire, in honour of the falfe god Moloch ; and he offered facrifices and incenfe upon the high places, upon hills, and in groves. Rezin king of Sy¬ ria and Pekah king of Ifrael invaded Judea in the be¬ ginning of the reign of Ahaz ; and having defeated his army and pillaged the country, they laid fiege to Jerufalem. When they found that they could not make themfelves mafters of that city, they divided their army, plundered the country, and made the inhabitants prifoners of war. Rezin and his part of the confede¬ rate army marched with all their fpoil to Damafcus; but Pekah with his divifion of the army having at¬ tacked Ahaz, killed 120,000 men of his army in one battle, and carried away men, women, and children, without diftinftion, to the number of 200,000. But as they were carrying thofe captives to Samaria, the prophet Oded, with the principal inhabitants of the T t 2 city. Ahab II Ahaz. AHA I 332 J AHA city, came out to meet them; and by their remon- ftrances prevailed with them to fet their prifoners at , liberty. At the fame time, the Philiftines and Edo¬ mites invaded other parts of his land, hilled multitudes of the people, and carried off much booty. In this diftrelfed condition, Ahaz finding no other remedy for his affairs, fent ambaffadors to Tiglath-pilefer king of the Affyrians; and to engage him to his intereff, he ilripped the temple and city of all the gold which he could meet with, and "fent it as a prefent. Accor¬ dingly Tiglath-pilefer marched to the affiilance of Ahaz, attacked Rezin and killed him, took his capital Damaf- cus, deftroyed, it and removed the inhabitants thereof to Cyrene. The misfortunes of this prince had no influence to make him better : on the contrary, in the times of his greateft afflidlion, he facrificcd to the Syrian deities, whom he looked upon as the authors of his calamities, and endeavoured to render propitious to him, by honouring them in this manner; He broke in pieces the veffels of the houfe of God, (hut up the gates of the temple, and erefted altars in ail parts of jerufalem. He fet up altars likewife in all the cities of Judah, with a defign to offer incenfe on them. At length he died, and was buried in Jerufalem, but not in the fepulchres of the kings of Judah his pre- deceffors; which honour he was deprived of, on ac¬ count of his iniquitous courfe of life. Hezekiah his fon fucceeded him in the year of the world 3278, before Jefus Chrift 726. AHAZ I AH, the fon and fucceffor of Ahab king of Ifrael, reigned two years, part alone, and part with his father Ahab, who ordained him his af- fociate in the kingdom a year before his death. Aha- ziah imitated his father’s impieties (1 Kings xxii. 52, feq.), and paid his adoration to Baal and Altai te, the vvorlhip of whom had been introduced in Ifrael by Je¬ zebel his mother. The Moabites, who had been al¬ ways obedient to the kings of the ten tribes ever fince their feparation from the kingdom of Judah, revolted after the death of Ahab, and refufed to pay the ordi¬ nary tribute. Ahaziah had not leifure or power to reduce them (2 Kings i. 1, 2, See.) : for about the fame time, having fallen through a lattice from the top of his houfe, lie hurt himfelf confiderably, and fent meffengers to Ekron, in order to confult Baal- zebub, the god of that place, whether he _ fhould recover of the indifpofition occafioned by this ac¬ cident. But the prophet Elijah went to Ahaziah, and declared that he fliould not recover from his ill- nefs: and accordingly he died in the year of the world 3108, and Jehoram his brother fucceeded to the crown. Ahaziah, king of Judah, the fon of Jehoram and Athaliah, fucceeded his father in the kingdom of Ju¬ dah in the year,of the world 3119. He walked in the ways of Ahab’s houfe, to which he was allied, his mother being of that family. He reigned only one year, being flain by Jehu the fon of Nimihi.

AHIJAH, the prophet of Shilo. He is thought to be the perfon who fpoke twice to Solomon from God, once while he was building the temple (1 Kings vi. 11.), at which time he promifed him his protec¬ tion ; and at another time (/V. xi. 6.) after his falling into all his irregularities, when God expreffed his in¬ dignation with great threatenings and reproaches. A- hijah was one of thofe who wrote the annals or hiftory of this prince (2 Chr. ix. 29.). The fame prophet declared to Jeroboam that he would ufurp the king¬ dom (1 Kings xi. 29, &c.), and that two heifers fliould alienate him from the Lord, meaning the golden calves eredted by Jeroboam, one at Dan, the other at Bethel. About the end of Jeroboam’s reign, towards the year of the world 3046, Abijah the fon of that prince fell fick ; upon which Jeroboam fent his wife to this pro¬ phet to inquire what would become of the child. The queen therefore went to Ahijah’s houfe in Shilo, difgui- fed: But the prophet, upon hearing the found of her feet, faid, “ Come in, thou wife of Jeroboam, why feigneft thou thyfelf to be another ? for I am fent 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 houfe for his impieties ; that fo foon as fne would enter into the city her fon Abijah fliould die, and fliould be the only one of Jeroboam’s houfe that, fliould come to the grave or receive the honours of a burial. Ahijah in all probability did not long furvive the time of this laft prophecy ; but with the time and maimer of his death we are not ac¬ quainted. AHITOPHEL, a native of Gillo, was for fomc time the counfellor of king David, whom he at length deferted, by joining in the rebellion of Abfalom. This prince, upon his being preferred to the crown by the greateft part of the Ilraelites, fent for Ahitophel from Gillo (2 Sam. xv. 12.) to aflift him with his advice in the prefent ftate of his affairs: for at that time Ahi- tophel’s counfels were received as the oracles of God. himfelf (chap. xvi. Nothing gave David more unealinefs than this event; and when Huflrai his friend came to wait on him and attend him in his flight, he intreated him to return rather to Jerufalem, make a. fliow of offering his fervices to Abfalom, and endea¬ vour to fruftrate the prudent meafures which fliould be propofed by Ahitophel. When Abfalom was come to Jerufalem, he defired Ahitophel to deliberate with his other counfellors upon the meafures which were proper for him to take. Ahitophel advifed him in the firft place to abufe his father’s concubines ; fo that when his party Ihould underftand that he had diflionoured his father in this manner, they might conclude -that there were no hopes of a reconciliation, and therefore efpoufe his intereft more refolutely. A tent, therefore, being prepared for this purpofe upon the terrafs of the king’s palace, Abfalom, in the fight of all lira el, lay with his father’s concubines. The next thing A- hitophel propofed was in the terms following : “ Let me now choofe out 12,000 men, and I will arife and purfue after David this night, and I will come upon him while he is. weary and weak-handed, and I will make him A H U [ 333 ] A J A .Ahmella him afraid, and all the people that are with him (hall flee, j II. and I will finite tlie king only ; and I will bring back all Ai~* , the people unto thee; the man whom thou feekeft is as if all returned; fo all the people {hail be in peace.” This advice was very agreeable to Abfalom and all the elders of Ifrael. However, Abfalom delired Huftiai to be call¬ ed to have his opinion. Hufhai being come, and hear¬ ing what advice Ahitophel had given, faid, The coun- fel which Ahitophel has given is not good at this time; what, for the prefent, in my opinion, may do better, is this : Let all Ifrael be gathered unto thee, from Dan even to Beerflieba, as the fand that is by the fea for multitude, and put thyfelf in the midit of them, and wherever David is, we may fall upon him, and over¬ whelm him with our numbers, as the dew falleth upon the ground. This lalt advice being more agreeable to Abfalom and all the elders of Ifrael, was preferred ; upon *which Ahitophel faddled his afs, went to his houfe at Gillo, hanged himfeif, and was buried in the fepulchre of his fathers. He forefaw, without doubt,, all that would happen in confequence of Hufhai’s ad¬ vice, and was determined to prevent the death which he had deferved, and which David would probably have, in flitted on him, as foon as he fiiouldbe refettled on his throne.

AI, (anc. gepg.) a town in Judea, to the north of Jericho, called A'v t by Jofephus, and the inhabitants Ainatce. Joftiua having fent a detachment of 3000 men againtt Ai, God permitted them to be repulfed on account of Achan’s fin, who had violated the anathema pronounced againft the city of Jericho. But after the expiation of this offence, God commanded Joftiua (chap, viii.) to march with the whole army of the If- raelites againft Ai, and treat this city and the kingdom thereof as he had treated Jericho, with this difference, that he gave the plunder of the town to the people. Joftiua fent by night 30,000 men to lie in ambufti be¬ hind Ai; having firft well inftrudted thofe who had the command of them in what they were to do; and the next day, early in the morning, he marched againft the city with the remainder of his army. The king of Ai perceiving them, fallied haftily out of the town with all his peopk, and fell upon the forces of the Ifraelites; who upon the firft. onfet fled, as if they had been under fome great terror... As foon as Joftiua faw the enemy all out of the gates,. he raifed his ftiield upon the top of a pike, which was the fignal given to the ambufeade; whereupon they imme¬ diately entered the place, which they found without defence, and fet fire to it. The people of A.i percei¬ ving the fmoke afeending, were willing to return, but difeovered thofe who had fet fire to the city in their rear, while Joftiua and thofe who were with him turn¬ ing about, fell upon them, and cut them in pieces. The king was taken alive, and afterwards put to- death. The chevalier Folard obferves, that Joftma’s enter- prife on Ai, excepting in fome particulars of military- art, is very like that of Gibeah, which is fcarce any thing more than a copy of it. It would appear, fays that writer, by the feripture account, that Joftiua was not the author of the ftratagem made ufe of by him: for when God diredls himfelf to Joftma, he fays, ‘ Go 4 up againft Ai» lay an ambufeade behind the town ; I 4 have delivered the king and the people of it into thine 4 hands:’ yet notwithftanding this, God might leave the whole glory of the invention and execution of it to him, as to a great general.. 4 Joftiua arofe,’ fays the facred author, 4 and all the people of war, to go up a- 4 gainft Ai (verfe 3.) ; and Juftiua chofe 00130,000 4 mighty men of valour, and fent them away by night.’ Folard remarks, that there is a manifeft contradiction between this verfe and the 12th, wherein it is faid, that Joftiua chofe out 500 men, whom he fent to lie in, ambufti, between Bethel and Ai. How is this to be reconciled ? Calmet fays, that Mafius allows but 5000 men for the ambufeade, and 25,000 for the attack of the city, being perfuaded that an army of 6oo;coo men could only create confufion on this occafion, with¬ out any neceflity for, or advantage in, fuch numbers : but the generality of interpreters, continues Calmet,. acknowledge two bodies to be placed in ambufeade,, both between Bethel and Ai; one of 25,000, and the: other of 5000 men. With regard to the fignal Joftiua made to that part of his army which lay in ambufeade, the learned Fo¬ lard embraces the opinion of the Rabbins, who believe what is called the ftiield to be too fmall to ferve for a fismal: hence they make it to be the ftaff of one of their colours: from this, our author concludes, that the whole colours were ufed on the occafion; for in - the Afiatic ftyie, which is very near the poetic, the part is oftentimes to be taken for the whole.

He was fo enraged that the arms of Achilles were adjudged to Ulyffes, -that he immediately became mad.

This govern¬ ment has nine large parifties; and is divided into four parts, Aigle, Bex, Olon, and Ormont. This laft is among the mountains, and joins to Rougement. It is a double valley, abounding in pafture-lands. Ivor- na, in the diftridf of Aigle, was in part buried by jhe fall of a mountain, occafioned by an earthquake inji 584.

It is not known of what family he was. His authority and riches were great, and fo alfo in appearance was his piety. He founded the abbey of Cerne, in Dorfet- fhire ; and had fo great a veneration for Eadwald, the brother of St Edmund the martyr, who had lived a hermit in that country, near the filver well, as they called it, that, with the affiftance.of Archbilhop Dun- ftan, he tranflated his relics to the old church of Cernel. In 1016, when Canute, the fon of Suane, in¬ vaded England, and found himfelf ftoutly oppofed by that valiant Saxon prince Edmund Ironfide, the fon of iEthelred, this Earl Ailmer, with that arch traitor Eadric Streone, Earl of Mercia, and Earl Algar, join¬ ed the Dane againll their natural prince, which was one great caufe of the Saxons ruin. He did not long furvive this; and we find mentioned in hiftory only one fon of his, whofe name was aEthelward, Earl of Corn¬ wall, who followed his father’s maxims, and was pro¬ perly rewarded for it. For in 1018, Canute reaping the benefit of their treafons, and perceiving that the traitors were no longer ufeful, he caufed the infamous Eadric Streone, and this Earl iEthelward, to be both put to death. AILRED, or Ealred, abbot of Revefby in Lin- colnfnire, in the reigns of Stephen and Henry II. He was born in 1109* of a noble family, and educated in Scotland with Henry the fon of king David. On his return to England, he became a monk of the Ciftertian order, in the monaftery of Revefby, of which he after¬ wards was made Abbot. He died on the 12th of Ja¬ nuary 1166, aged 57, and was buried in his mona¬ ftery. “ He was (fays Leland) in great efteem du¬ ring his life ; celebrated for the miracles wrought after his death ; and admitted into the catalogue of faints.” He was author of feveral works ; moll of which were publilhed by Gilbo the Jefuit at Douay, 1631 part of them may be alfo found in the "Bibliotheca Cifiertien- Jis, and Bibliotheca Patrum. His principal woncs is the Speculum charitatis. Leland, Bale, and Pits, mention feveral manufcripts which never were publiihed. AILSA, an infulated rock on the weftern coaft of Scotland, between the ftiores of Airlhire and Cantire. It is two miles in circumference at the bafe, is accef- fible only at one place, and rifes to a great height in a pyramidical form. A few goats and rabbits pick up a fubfiftence among the ftiort grafs and furze ; but the importance of the rock confifts in the great variety and boundlefs numbers of birds, by which it is frequented, particularly the gannets or folan-geefe, whofe young are ufed at the bell tables, and bring a good price. Other birds are caught for their feathers. The rock is rented from the Earl of Caffilis at L. 3.3 per annum. The depth of water around the bafe is from 7 to 48 fathoms. It is furrounded with excellent banks, well flocked with cod and other white filh.

His ikill in the Hebrew language, and his ex¬ cellent Annotations on the Holy Scriptures, which are ftill highly efteemed, gained him great reputation. He alfo wrote feveral pieces in defence of the Brownifts, and feveral other works. Ainsworth (Robert), born at Woodyale in Lan- caftiire in 1660, was mafter of a boarding-fchool at Bethnal-green, from whence he removed to Hackney, and to other places in the neighbourhood of London. After acquiring a moderate fortune, he retired, and lived privately till the time of his death, which happen¬ ed in 1743. are indebted to him for the beft La¬ tin and Englifh Didlionary extant: he publifhed it in quarto 1736 ; and in' 1752, the fourth edition, under the care of Dodlor Ward of Greftiam College, and the Rev.

They will plcafe to advert, that the one of thefe tubes communicates with the atmofphere at the bottom of the houfe, and the other towards the top: the opening of the one is beneath the level of the room, that of the other above it. Now, as the air is more denfe at the fur- face of the ground than at any height above it, the warm rarefying air will naturally iffue at that opening where it meets with leaft refiftance, which muft invariably be through that which opens to the external air at the great - eft height; and as the cool air will naturally be preffed into the room by that opening where the air is moft weighty, this muft invariably be by that which is neareft the furface of the earth. AIR [ 337 I AIR Air equal degrees of heat and cold, as are -unavoidable ’ .

In warmer regions, or during the fummer-feafon, there can be no objection to the wheel-ventilator in the window.—It is a Ample contrivance, and a fafe and effectual mean of preferring the air in our apartments fweet and wholefome at that feafon.” It is a vulgar error among many people, to believe that fire purifies the contaminated air, by deftroying the noxious particles mixed with it; and for this rea- fon they think, that the fire kept in a room where the air is tainted, purifies the room, by rendering the air in it again fit for refpiration. Indeed, a fire kept in a room or apartment where the air is tainted, as is the cafe with hofpitals, goals, and the like, does certainly purify the apartment, and the practice is very ufeful; but this effect is only becaufe the fire promotes the circulation of the air, and dries the dampnefs of rooms, furniture, &c.: fo that it is not the infected air that is purified, but is new, frelh, and wholefome air, that by the action of the fire has taken the place of the infect¬ ed air; which infected air, being rarefied by the heat, has been expelled from the apartment. Fire and com- buftion in general is fo far from purifying contami¬ nated air, that it actually contaminates a prodigious quantity of it in a Ihort time ; fo that not only a com¬ mon fire, but even a lighted candle, when kept in a well-clofed room, wherein the external air has not a free accefs, inltead of purifying, renders the air of that room noxious.

AIR Balloons, a general name given to bags of any light fubftance filled with inflammable air, or other permanently elaftic fluid, whofe fpecific gravity is con- fiderably lefs than that of common atmofpheric air. The confequence of their being filled in this manner is, that if they are of any confiderable magnitude, they afcend in the air to an amazing height; and will not only afcend in this manner by themfelves, but carry up along with them great weights, and continue to rife till they at¬ tain an height in which the circumambient air is of the fame fpecific gravity with themfelves. In this fitua- tion they will either float or be driven in the direction of the wind or current of air in which they are expo- fed, remaining in thefe elevated regions till the fluid efcapes by the burfting of the bags from the fuperior elafticity of the fluid, or by its gradual evaporation through the pores of the envelope.

See Comparative Ana¬ tomy, chap. iii. and Ichthyology. i Plate VII Aiu-Gun, a pneumatic machine for exploding bul¬ lets, &c. with great violence. The common air-gun is made of brafs, and has two barrels ; the infide barrel A, fig. 8. which is of a fmall bore, from whence the bullets are exploded) and a large barrel ECDR on the outfide of it. There is a fyringe SMNP fixed in the ftock of the gun, by which the Vol. I. Part I. air is injefled into the cavity between the two barrels Air-gun. through the valve E P. The ball K is put down into ' v~““ its place in the fmall barrel, with the rammer, as in any other gun. At S L is another valve, which, being opened by the trigger O, permits the air to come be¬ hind the bullet, fo as to drive it out with great force. If this valve be opened and (hut fuddenly, one charge of condenfed air may be fufficient for feveral difcharges of bullets ; but if the whole air be difcharged on one fingle bullet, it will drive it out with a great force. This difcharge is effe&ed by means of a lock, fig. 9, placed here as ufual in other guns ; for the trigger be¬ ing pulled, the cock will go down and drive the lever O, fig. 8. which will open the valve, and let in the air upon the bullet K. Air-guns of late years have received very great im¬ provements in their conltruftion. Fig' 10. is a repre- fentation of one made by the late Mr B. Martin of London, and now by feveral of the mathematical in- ftrument and gun makers of the metropolis. For fim- plicity and perfection it exceeds any other heretofore contrived. A is the gun-barrel, with' the lock, Hock, ram-rod, and of the fize and weight of a common fowling-piece. Under the lock, at h, is a round Heel tube, having a fmall moveable pin in the infide, which is puflied out when the trigger a is pulled, by the fpring- work within the lock ; to this tube L a hollow copper- ball c fcrews, perfectly air-tight. This copper ball is fully charged with condenfed air by the fyringe B (fig. 7.) previous to its being applied to the tube b of fig. 10. It is then evident, that if a bullet be rammed down in the barrel, the copper ball fcrewed fall at £, and the trigger a be pulled, that the pin in b will, by the aftion of the fpring-work within the lock, forcibly ftrike out into the copper ball; and thereby pufhing in fuddenly a valve within the copper ball, let out a por¬ tion of the condenfed air; which air will ru(h up thro’ the aperture of the lock, and forcibly aft againft the bullet, driving it to the diftance of 60 or 70 yard* or further. If the air is ftrongly condenfed at every difcharge, only a portion of the air efcapes from the ball; therefore, by re-cocking the piece, another dif¬ charge may be made; and this repeated to the amount of 15 or 16 times. An additional barrel is fometimes made, and applied for the difcharge of (hot, inftead of the one above defcribed. The air in the copper ball is condenfed by means of the fyringe B (fig.7.), in the following manner: The ball c is fcrewed quite clofe on the top of the fyringe at bf at the end of the fteel pointed rod: a is a flout ring through which paffes the rod k : upon this rod the feet ufe to be formerly fet; then the hands are to be applied to the two handles i fixed on the fide of the barrel of the fyringe. Now by moving the barrel B fteadily up and down on the rod a, the ball c will become charged with condenfed air; and it may be ea- fily known when the bail is as full as poffible, by the irrefiftible adlion that the air makes againft the pifton when you are working the fyringe. At the end of the rod k is ufually a four-fquare hole, which witli the rod ferves as a key to fallen the ball c fall on the fcrew b of the gun and fyringe clofe to the orifice in the ball c. In the infide is fixed a valve and fpring, which gives way for the admiflion of air ; but upon its emiflion comes clofe up to the orifice, (hutting up the internal A I R Air-^un. air. The pifton-rod works air-tight, by a collar of v leather on it, in the barrel B ; it is therefore plain, when the barrel is drawn up, the air will rufh in at the hole h. When the barrel is pufhed down, the air there¬ in contained will have no other way to pafs from the prefliire of the pifton but into the ball c at top. The barrel being drawn up, the operation is repeated, until the condenfation is fo ftrong as to refill the adlion of the pillon. Sometimes the fyringe is applied to the end of the barrel C (fee lig. x i.); the lock and trigger Ihut up in a brafs cafe*/; and the trigger pulled, or difcharge made, by pulling the chain b. In this contrivance there is a round chamber for the condenfed air at the end of the fyringe at e, and it has a valve a&ing in a fimilar man¬ ner to that of the copper ball. When this inftrument is not in ufe, the brafs cafe d is made to Hide off, and the inft'rument then becomes a walking-ftick; from which circumftance, and the barrel being made'of cane, brafs, &c. it has received the appellation of the Air- cane. The head of the cane unfcrews and takes off at «, where the extremity of the pifton-rod in the barrel is Ihown : an iron rod is placed in a ring at the end of this, and the air condenfed in the barrel in a fimilar manner to that of the gun as above; but its force of adlion is not near fo ftrong and permanent as that of the latter. The Magazine AiR-gun was invented by that inge¬ nious artift L. Colbe. By this contrivance ten bullets are fo lodged in a cavity, near the place of difeharge, that they may ba drawn into the Ihooting-barrel, and fucceflively difcharged fo fall as to be nearly of the fame ufe as fo many different guns. Fig. 12. reprelents the prefent form of this machine, where part of the ftock is cut off, to the end of the in- jedling fyringe. It has its valve opening into the ca¬ vity between the barrels, as before. K K is the fmall Ihooting-barrel, which receives the bullets from the magazine- ED, which is of a ferpentine form, and> doled at the end D when the bullets are lodged in it. The circular part abc, is the key of a cock, having a cylindric hole through it, / i, which is equal to the bore of the fame barrel, and makes a part of it in the prefent fituation. When the lock is taken off, the fe- veral parts R, T, W. &c. come into view, by which means the difcharge is made by pufhing up the pin P/>, which raifes and opens a valve V, to let in the air againft the bullet I, from the cavity F F; which valve is im¬ mediately Ihut down again by means of a long fpring ef brafs N N. This valve V being a conical piece of brafs, ground very true in the part which receives it, will of itfelf be fufficient to confine the air. To make a difcharge, you will pull the trigger ZZ, which throws up the leer y ay and difengages it from the notch a, upon which the ftrong fpring WW moves the tumbler T, to which the cock is fixed. This, by its end u, bears down the end v of the tumbling lever Pv, which, by the other end m, raifes at the fame time the fiat end of the horizontal lever Qj and by this means, of courfe, the pin Pp, which Hands upon it, is puIhed up, and thus opens the valve V, and difeharges the bullet. This is all evident from a bare view of the figure. To bring another bullet to fucceed that marked I, ■ inftamaneoufly, turn the cylindric cavity of the key of A I R the cock, which before made part of the barrel R K, Air-gun into the fituation i k, fo that the part i may be at K j . II. and hold the gun upon your Ihoulder, with the bar- Air P1Pe»-i rel downwards and the magazine upwards, by which means that bullet next the cock will fall into it out of the magazine, but go no farther into this cylindric cavity than the two little fprings //, which detain it. The two circles reprefent the cock-barrel, wherein the key abovementioned turns upon an axis not reprefent.- ed here, but vifible in fig. 13. This axis is a fquare piece of Heel, on which comes the fquare hole of the hammer H, fig. 14.; by which the cylindric cavity mens- tioned is opened to the magazine. Then opening the hammer, as in that figure, the bullet is brought into its proper place near the difcharge-valve, and the cylindrie cavity of the key of the cock again makes part of the inward barrel KK. It evidently appears how expeditious a method this is of charging and difeharging a gun; and were the force of condenfed air equal to that of gun-powder, fuch an air-gun would anfwer the end of feveral guns. In the air-gun, and all other cafes where the air is required to be condenfed to a very great degree, it will be requilite to have the fy.ringe of a fmall bore, viz. not exceeding half an inch in diameter ; becaufe the preffure againft every fquare inch, is about 1.5 pounds* and, therefore againft every circular inch about 12 pounds. If therefore the fyringe be one inch in dia¬ meter, when one atmofphere is injected, there •will be a refillance of 12 pounds againft the .pifton ; and when 10 are injedled, there will be a force of 120 pounds to be overcome ; whereas 10 atmofpheres a£t againft the circular half-inch pifton (whofe area is only one-fourth part fo big) with only a force equal to 30 pounds j or 40 atmofpheres may be injefted with fuch a fyringe, as well as 10 with the other. In ftiort, the facility of- working will be inverfely as the fquares. of the diame¬ ter of the fyringe. Am-Jacket, a fort of jacket made of leather, in which are feveral bags, or bladders, compofed of the fame materials, communicating with each other. Thefe are filled with air through a leather tube, having a brafs ftop-cock accurately ground at the extremity, by which means the air blown in through the tube is confined in the bladders. The jacket mull be wet, before the air be blown into the bags, as otherwife it will immediate¬ ly efcape through the pores of the leather. By the help of thefe bladders, which are placed near the bread*, the perfon is fupported- in the water, without making the efforts ufed in fwimming. Am- Pipes, an invention for drawing foul air out of Ihips, or any other clofe places, by means of fire* Thefe pipes were firft found out by one Mr Sutton, a brewer in London ; and from him have ,got the name of Sutton's Air-pipes. The principle on which their operation depends is known to every body,, being in» deed no other than that air is neeeffary for the fup- port of fire; and, if it has not accefs from the plai¬ ces moft adjacent, will not fail to come from thofe that are more remote. Thus, in a common furnace, the air enters through the afh-hole; but if this is do* fed up, and a hole made in the fide of the furnace, the air will rufh in with great violence through that holei If a tube of any length whatever is inferted in this hole, the air will rufh through the tube into the fire, and of coa- 1 338 1 T g IT AIR .

And thus it feems plain, from what has been already faid, that there will be, from the hold, a conftant difcharge of the air therein contained; and confequently, that that air, fo difcharged, mufl be as conilantly fupplied by frefh air down the hatches or fuch other communications as are opened into the hold ; whereby the fame mufl be continually frefhened, and its air rendered more whole- fome and fit for refpiration. “ And if into this principal pipe fo laid into the hold, other pipes are let in, communicating reipective- ly either with the well or lower decks; it mull follow, that part of the air, coniumeS in feeding the tire, muil be reipectiveiy drawn out of all fuch places to which the communication ihall be fo made.” This account is fp plain, that no doubt can remain on an axis. - It was divided into 12 parts, by means of partitions placed like the radii of a circle. Thefe par¬ titions did not extend quite to the centre, but left an open fpace of about i8 inches diameter in the middle ; towards the circumference, they extended as far as pof- fible without interfering with the cafe, fo that the wheel might always be allowed to turn freely.—Things being thus cifcumflanced, it is plain, that if the wheel was turned towards that fide of the box on which the trunk was, every divifioh would pufh the air before it, and drive it out through the trunk, at the fame time that frefh air would come in through the open fpace at the centre, to fupply that which was thrown out thro’ the trunk. By turning the wheel fwiftly, a flrong blafl of air would be continually forced out thro’ the fquare trunk, on the fame principles on which a common fan¬ ner winnows corn. If the wheel is turned the oppofite way, a draught of air may be produced from the trunk to the centre. If this machine, then, ik placed in room where a circulation of air is wanted, and the trunk made to pafs through one of the walls ; by turning the wheel fwiftly round, the air will be forced with great velocity out of that room, at the fame time that frefh air will enter through any chinks by which it can have accefs to fupply that which has been forced out. It is evident, that the circulation which is promoted by this machine, is entirely of the fame kind with that produced by Mr Sutton’s; the turning of the wheel in Mr Defagulier’s machine being equivalent to the rare- fadlion of the air by fire in Mr Sutton’s: but that the latter is vallly fuperior, as adling of itfelf, and without intermiffion, requires no arguments to prove. Mr Sut¬ ton’s machine has yet another conveniency, of which no other contrivance for the fame purpofe can boafl j namely, that it not only draws out putrid air, but de- flroys it by caufing it pafs through fire; and experience has abundantly fhown, that th6ugh putrid air is thrown into a great quantity of frefh air, it is fo far from lo- fing its pernicious properties, that it often produces noxious difeafes. We do not fay, indeed, that putrid air becomes falutary by this means; but it is undoubt¬ edly rendered lefs noxious than before; tho’ whether it is equally innocent with the fmoke of a fire fed in the common way, we cannot pretend to determine. Befides this machine by Mr Defaguliers, the venti- concerning the efficacy of the contrivance: it is evi- lators of Dr Hales, already mentioned, and thofe dent, that, by means of pipes of this kind, a conftant circulation of frefh air would be occafioned thro’ thofe places where it would otherwife be moll apt to llagnate and putrefy. Several other contrivances have been ufed for the fame purpofe ; and Dodtor Hales’s ventilators, by iome unaccountable prejudice, have been reckoned fuperior in efficacy and even limplicity to Mr Sutton’s machine, which at its firll invention met with great • See Swf- oppofition and even when introduced by Dr Mead, called 'wind-fails. are likewife ufed for the fame purpofe. The former of which is an improvement of the Heffian- bellows*: the other is a contrivance-for throwing frefh * See Vtr, air into thofe places where putrid air is apt to lodge; i’.a or. but this has the lafl-mentioned inconvenience in a much greater degree than any of the others, as the blafl of frefh air throws out that which was rendered putrid by flagnation, in fuch a manner as to contami¬ nate all around it. See Wiub-&i//r. ;U u 2 Aits A I R Air-trunk Am-Trunk, is alfo a contrivance by Doftor Hales II to prevent the ftagnation of putrid effluvia in jails, Air-mafts. Qther placeg wi1ere a great number of people are »'’ ■ Growcieci together in a fmall fpace. It confifts only of a long fquare trunk open at both ends; one of which is inferted into the ceiling of the room, the air ,of which is required to be kept pure; and the other extends a good way beyond the roof. Through this trunk a continued circulation is carried on : and the reafon is, that the putrid effluvia which do fo much mifchief when colle&ed, being much lighter than the pure atmofphere, arife to the top of the room ; and, if they there find a. vent, will continually go out through it. Thefe effluvia arife in very confiderable quantity, being calculated by the late DrKeil at no lefs than 39 ounces from one man in, 24 hours. Thefe trunks were firft made trial of by Mr Yeoman, over the Houfe of Commons, where they were nine inches wide within; and over the Court of King’s-bench in Wdlminfter-hall, where they were fix inches wide. They are fometimes made wider, and fometimes nar¬ rower : but the wider they are the longer they ought to be, more effe&ually to promote the afcent of the va¬ pour. The reafon why vapours of this kind afcend more fwiftly through a long trunk than a fflort one, is, that the preiTure of fluids is always according to their different depth, without regard to the diameter of their bafis, or. of the veffel which contains them; and, upon this principle, a gallon of water may be made to fplit aflrong calk. See Hydrostatics. When the co¬ lumn of putrid effluvia is long and narrow, the differ¬ ence between the column of atmofphere preffing on the upper end of the trunk, and that which preffes on the lower end, is much greater than if; the column of pu¬ trid effluvia was fhort and wide; and coniequendy the afcent is much fwifter.—One pan of a fingle pair of fcales, which was two inches in diameter, being held within one of thefe trunks over the Houfe of Commons, the force of the afcending air made it rife fo as to re¬ quire four grains to reftore the equilibrium, and this when there was no perfon in the houfe; but when it was full, no lefs than 12 grains were requifite to re- flore the equilibrium ; which clearly Ihows that thefe trunks muff be of real and very great efficacy.

AiR-Shafts, among miners, denote holes or ftiafts let down from the open air to meet the adits and fur- niih frelh air. The damps, want, and impurity of air which occur, when adits are wrought 30 or 40 fathoms long, make it neceffary to let down air-fhafts, in order to give the air liberty to play through the whole work, and thus difcharge bad vapours, and furnilh good air for refpiration : the expence of which lhafts, in regard of their vaft depths, hardnefs of the rock, drawing of water, &c. fometimes equals, nay exceeds, the ordinary charge of the whole adit. Sir Robert Murray deferibes a method, ufed in the coal-mines at Liege, of working mines without air- fliafts. When the miners at Mendip have funk a groove, they will not be at the charge of an air-ftiaft till A I R they come at ore; and for the fupply of air have Air-thrcadj boxes of elm exaftly clofed, of about fix inches in the fl clear, by which they carry it down about twenty fa- , Air- thorns. They cut a trench at a little diftance from the top of the groove, covering it with turf and rods difpofed to receive the pipe, which they contrive to come in fideways to their groove, four feet from the top; which carries down the air to a great depth. When they come at ore, and need an air-fhaft, they fink it four or five fathoms diftant, according to the convenience of the breadth, and of the fame faftiion with the groove, to draw as well ore as air. Air-Tbreads% in natural hiffory, a name given to the long filaments, fo frequently feen in autumn float¬ ing about in the air. Thefe threads are the wmrk of fpiders, efpecially of that fpecies called the long-legged field-fpider; which, having mounted to the fummit of a buffi or tree, darts from its tail feveral of thefe threads, till one is produced capable of fupporting the creature in the air: on this it .mounts in queft of prey, and frequently rifes to a very confiderable height. See Aranea. AiR-VeJfels, are fpiral dudts in the leaves, &c. of plants, fuppofed to be analogous to the lungs of ani¬ mals, in fupplying the different parts of a plant with air. See the article Plants. Air, in mythology, was adored by the Heathens un¬ der the names of Jupiter and Juno ; the former repre- fenting the fuperior and finer part of the atmofphere, and the latter the inferior and groffer part. The augurs alfo drew prefages from the clouds, thunder, light¬ ning, &c. Air, in painting, &c. denotes the manner and-very life of adtion ; or it is that which expreffes the difpofi- tion of the agent.—It is ibmetimes alfo ufed in afyno- nymous fenfe with gefture or attitude. Air, in mufic, is taken in different fenfes. It is fometimes contrafted with harmony; and, in this fenfe, it is fynonymous with melody in general.— Its proper meaning is, A tune, which is fet to words, or to ftiort pieces of poetry that are called fongs. In operas, we give the name of air to fuch pieces of mufic as are formed with meafures and cadences, to di- llinguifh it from the recitative ; and, in general, every piece of mufic is called an air, which is formed for the voice, or even for inftruments, and adapted to ftanzas, whether it forms a whole in itfelf, or whether it can be detached from any whole of which it forms a part, and be executed alone. If thefubjedt admits of harmony, and is fet in parts, the air is, according to their number, denominated a duett, a trio, a quartet to, &c. We need not follow Rouffeau, and the other philologifts, in their endeavours to inveftigate the etymon of the word air. Its deriva¬ tion, though found and afeertained, would contribute little to illuftrate its meaning in that remote fenfe, to which, through a long continuance of time, and the various viciffitudes of language, it has now paffed. The curious may confult the lame article in the DUiionnaire de Mufique by M. Rouffeau. In modern mufic, there are feveral different kinds of airs, each of which agrees to a certain kind of dancing, and fiom thefe dances the airs themfelves take their fpecific names. The airs of our operas, are, if we may be permitted the [ 34° ] A I R the exnrefiion, the canvafs or fubftratum upon w iich are painted all the pictures of imitative mufic ; melody is the defign, and harmony the colouring; every pictu- refq.ue objeft felefted from the moft beautiful parts of nature, every refte&ed fentiment of the human heart, are the models which the artift imitates^ whatever gains attention, whatever interefts the foul, whatever charms the ear, or caufes emotion in the heart, thefe are the obje&s of his imitation. • See Imitation.- An air which delights the ear, and difcovers the learning of the compofer ; an air in vented by genius, and compofed with tafte; is the nobleft effort of mufic: it is this which explores the compafs,.and difplays the delicacy, of a beautiful voice; it is in this where the charms of a well-conducted fymphony fhine ; it is by this, that the paffions, excited and inflamed by nice gradations, reach and agitate the foul through the avenues of external fenfe. After hearing a beautiful air, the mind is ac- quiefeent and ferene: the ear is fatisfied, not difgufted: it remains imprefled on the fancy, it becomes a part of our eflence, we carry it with us, we are able to repeat it at pleafure: without the ability acquired by habit to breathe a Angle note of it, we execute it in our ima¬ gination in the fame manner as we heard it upon the theatre: one fees the feene, the adtor, the theatre ; one hears the accompaniments and the applaufes. The real enthuflafl in mufle never forgets the beautiful airs which he has heard ; when he choofes, he caufes the opera to recommence. The words to which airs are adapted, are not always rehearfed in regular fucceffion, nor fpoken in the fame manner with thofe of the recitative ; and though, for ordinary, they are very fhort, yet they are interrupted^ repeated, tranfpofed,|at the pleafure of the artift. They do not conilitute a narrative, which once told is over : they either delineate a pidlure, which it is neceffary to contemplate in different points of view; or infpire a fen¬ timent in which the heart acquiefces with pleafure, and from which it is neither able nor willing to be difen- gaged; and the different phrafes of the air, are nothing elfe but different manners of beholding the fame image. This is the reafon why the fubjedl of an air fhould be one. It is by thefe repetitions properly placed, it is by thefe redoubled efforts, that an impreflion, which at flrft was not able to move you, at length fhakes your foul, agitates you, tranfports you out of yourfelf: and it is likewife upon the fame principle, that the runnings, as they are called, or thofe long, mazy, and inarticu- lated inflexions of the voice, which, in pathetic airs, frequently feem, though they are not always fo, im¬ properly placed; whilft the heart is affected with a fen¬ timent exquifltely moving, it often expreffes its emo¬ tions by inarticulate founds, more ftrongly and fenflbly than it could do by words themfelves. The form of airs is of two kinds. The fmall airs are often compofed of two flrains, which ought each of them to be fung twice; but the important airs in ope¬ ras are frequently in the form of rondeaus. Air, ox Ayr, in geography, a town of Scotland, capital of an extenflve. county of the fame name. It Hands on the river Air, and was formerly a place of good trade, and feat of fifheries; all of which have vanifhed, and the people now live by one another. Air appears, from hi- fiory and other documents, to have been a conflderable place at the time of the Norman conqueft. The vouchers A X R of its antiquity are corroborated by an elegant building, Aira called the Crop, which hath efcaped the deftruXive . 0 rage of the laft and preceding century. The date on , Airinj?' this fragment of antiquity is 1055, confequently it hath Hood in its place above 730 years; and it is to be wilhed, that the majority of the inhabitants may unite in preferring it from being deftroyed by perfons who have exprelfed a ftrong defire to that purpofe. In 15:57, the tax levied upon Air was L. 236 Scots; upon Glafgow only L. 202. In 1771, Air was aflefled at 15 s. Sterl. and Glafgow at L. 18, 10s. In 1 751, the pickled herrings exported from Air were 6624 barrels; Ance the year 1777, none. Thefe revolutions appear the more extraordinary, when we conAder the very advan¬ tageous Atuation of Air both by land and water; the fertility of the country; the riches of the fea 4 its contiguity to the weftern Aflieries on one Ade, and to Glafgow on the other; the large returns for cattle, grain, and coal; the ample revenues of the town ; and particularly the conveniency of its harbour for Afhing- veflels of every conftruXion.—About a mile north from the town there is a lazar-houfe, commonly called The King's Chapel, which King Robert de Bruce fet apart for the maintenance of lepers. AIRA, in botany: A genus of the triandria digy’- nia clafs ; and in the natural method ranking under the 4th order, Gramina. The charaXers are : The calyx’ is a two-flowered double-valved glume : The corolla is two-valved, and no rudiment of a flower between the florets : The Jlamina conflft of three capillary filaments the length of the flower; the antherae are oblong, and forked at both ends: The piftillum is an egg-fhaped germen ; the ftyli are two, briftly, and expanding; the ftigmata are pubefeent: There is no pericarpium ; the including corolla grows to the feed : The feed is egg- fliaped and covered. There are 14 fpecies of the aira,. nine of which are natives of Britain. The Engliflr name is Hair-grafs. See the general article Grass. AIRANI, in church-hiftory, an obfeure feX of A- rians, in the fourth century, who denied the confubftan- tiality of the Holy Ghoft with the Father and the Son. They are otherwife called Airani/la; and are faid to have taken their name from one Airas, who diftinguifh- ed himfelf at the head of this part}-, in the reigns of Valentinian and Gratian.

AIRING, a term peculiarly ufed for the exercifing horfes in the open air. It purifies the blood; purges the body from grofs humours; and, as the jockies exprefs it, teaches the horfe how to make Ins wind rake equally, and keep time with the other motions of his body. It alfo flrarpens the ftomach, and keeps the creature hun¬ gry ; which is a thing of great confequence, as hunters and racers are very apt to have their llomach fall off, either from want of. exercife, or from the too violent exer- • [ 341 3 A J U [ 342 ] A I X exercife which they are often expofed to. If the horfe be over fat, it is befl to air him before fun-rife and j after fun-fetting ; and in general, it is allowed by all, that nothing is more beneficial to thofe creatures than early and late airings. -Some of our modern managers, however, difpute this: they fay, that the cold of thefe times is too great for tjie creature; and that if, in par* ticular, he is fubjedlto cattarrhs, rheums, or the like complaints, the dews and cold fogs, in thefe early and late airings, will be apt to increafe all thofe diforders. Nature, we fee, -alfo points out the fun-beams as of great ufe to thefe animals j thofe which are kept hardy and lie out all night, always running to thofe places where the funlhiae comes, as foon as it appears in a morning. This ftiauld feem to recommend thofe airings that are to be made before fun-fct, and a little time after fun-rife. As to the caution, fo earneftly in¬ culcated by Markham, of ufing thefe early and late airings for fat horfes, it is found unneceifary by many: for they fay, that the fame effeft may be produced by airings at warmer times, provided only that they are made longer; and that, in general, it is from long air¬ ings that we are to expedt to bring a horfe to a perfect wind and found courage. AIRvS, in the manege, are the artificial motions of taught horfes; as the demivolt, curvet, capriole, &c. AIRY, or Aery, among fportfmen, a term expref- fing the neft of a hawk or eagle. /hur Triplicity, among aftrologers, denotes the three figns, gemini, libra, and aquarius. AISNE, a river of France, which rifes in Cham¬ paign, and runs W. by Soifons in the Ifle of France, falling in to, the. river Oife, a little above Campeigne. AITOCZU, a. coafiderable river of Lelfer Afia, which, arifing in the mountain Taurus, falls into the fouth part of the Euxine.fea. .AJUGA, Bugle: A genus of the gymnolpermia order, -belonging to the didynamia clafs of plants ; and in,the natural method ranking under the 43d order, yifperifilia. The characters are: The calyx is a fliort -perianthium, mor.ophyllous and perfdlent: The corolla is monopetalous and grinning:; 'TXinJlamina conlift of four eredt Tubulated filaments ; the anthene are -dimi¬ diated : The pijhllum has a four-cleft germen, a fili¬ form ftylus, and two {lender ftigmata. There is no ps- rlca-pium ; the calyx converging, and containing the feeds in i ts bofom: The feeds are four, and oblong. The Species enumerated by Linnaeus are, /. The orienta- Iis, with inverted flowers, which is a native of the eaft. i. The genevenfis, with woolly leaves and hairy cups, is a native of. Swifferland and -of the fouthern parts of Europe. ,3. The pyramidalis, or mountain-bugle, with a fquare pyramidal fpike and blue flowers, is a native of Sweden, Germany, SwifTerland, and the hilly parts of Britain. Sheep and goats eat it; cows are not fond of it; horfes and fwine refufe it. 4. The reptans, com¬ mon or paflure bugle, with creeping fuckers, and blue, -red, or white blofibms, in long leafy fpikes, is a native of the fouthern parts of Europe, and is met with in woods and moift places in many parts of Britain. The roots are aftringent, and flrike a black colour'with vi¬ triol of iron. Culture, T. he firrt: fpecies is propagated by fowing the feeds foon after they are ripe, in a pot filled with loamy earth, and placed in a fliady fituation till autumn; when it mull be removed under a frame, and protefted Alu» from the frofts. In the fpring, after the plants are come up, let them be tranflated each into a feparate pot, and in fummer placed under a fhady fituation. The other , - forts are eafily propogated by -their fide-fhoots, and fucceed beft in a moift fliady fituation. AIUS locutios, the name of a deity to whom the Romans eredted an altar.—The words are Latin, and fignify “ a fpeaking voice.”—The following ac¬ cident gave occafion to the Romans creeling an altar to the Aius Locutius. One M. Seditius, a plebian, ac- quainted-the tribunes, that, in walking the ftreets by night, he had heard a voice over the temple of Vefta, giving the Romans notice that the Gaids were coming againft them. This intimation was however negle&ed ; but after the truth was confirmed by the event, Camil¬ las acknowledged this voice to be a new deity, and erec¬ ted an altar to it under the name of the Aius Lacutius. AJUTAGE, or Adjutage, a kind of tube fitted to the mouth of the vefiel through which the water of a fountain is to be played. To the different form and ffrufture of ajutages, is owing to the great variety of fountains. See Fountain and Hydrostatics. AIX, a fmall, but ancient town in the duchy of Sa¬ voy, with the title of a marquifate. It is feated on the lake Bourget, at the foot of a mountain, between Chamberry, Annecy, and Rumilly. There is here a triumphal arch of the ancient Romans, but it is almoft entirely ruined. The mineral waters bring a great number of ftrangers to this place. The place was o- riginally called Aqua Gratiana, from the hot baths built there by the Emperor Gratian. E. Long. 7.10. N. Lat. 45. 40. Aix, an ancient city, the capital of Provence, in France. It is an archbifhopric ; and has a parliament, a court of aids, a chamber of accounts, a fenefchal’s jurifdiftion, a generality, and an univerfity. It has that air of iilence and gloom fo commonly charafteriilic of places deftitute of commerce or iuduftry : It is, however, a well-built city; and moft like Paris of any place in the kingdom, as well for the largenefs of the buildings, as in refpeft of the politenefs of the inhabi¬ tants. It is embellifhed with abundance of fine foun¬ tains, and feveral beautiful fquares. The preachers fquare is on the fide of a hill; it is about 160 yards in length, and is furrounded with trees, and houfes built with ftone three {lories high. The town-hall is at one end of the city, and is diftributed into feveral fine a- partments: the two lowed are takeh up by the board of accounts, and by the fenefchal; that above is defign- ed for the feffions of parliament. The hall of audience is adorned with the pi&ufes of the kings of France on horfeback. The hotel of the city is a handfome build¬ ing, but hid by the houfes of the narrow ftreet in which it is placed. The cathedral church is a Gothic ftruc- ture, with tombs of feveral earls of Provence, and fome good pictures by French maflers. The Corfe, or Orbi- telle, is a magnificent walk, above 300 yards long, formed by a triple avenue of elms, and two rows of re¬ gular and {lately houfes. The church of the fathers of the oratory is a handfome building ; and not far from thence is the chapel of the blue penitents, which is full of paintings. The convent of preachers is very fine; in their church is a lilver ftatue of the Virgin Mary al¬ moft as big as the life. There are other churches and buildings 1 343 ] eleclor palafiru A I X in the quality of the duke of Ju- A I X Aix. buildings which contain a great number of rarities. The baths without the city, which were difcovered not long fince, have good buildings, raifed at a vaft ex¬ pence, for the accommodation of thofe who drink the waters. Although Aix was the firft Roman fettlement in Gaul, it is not remarkable for ancient remains. The warm fprings from which it is now known and fre¬ quented induced Sextus Calvinus to found a colony here, to which he gave the name of Aqute Sextice. They were fiippofed to poffefs particular virtues in cafes of debility ; and feveral altars have been dug up facred to Priapus, the infcriptions on which indicate their gra¬ titude to that deity for his fuppofed fuccbur and affift- ance.

Aix la chapelle, a fine city of Germany, in the circle of Weftphalia and duchy of Juliers. All authors are agreed about its antiquity, it being mentioned in Csefar's Commentaries and the Annals ef Tacitus. The Romans had colonies and fortrefles there, when they were at war with the Germans; but the mineral waters and the hot bath fo increafed its fame, that, in procefs of time, it was advanced to the privileges of a city, by the name of Aqusegranii, that ‘ is, the waters of Granius t that which it has now, of Jlix la Chapelle, was given it by the French, to di- ftinguifh it from the other Aix. It isfo called, on ac¬ count of a chapel built in honour of the Holy Virgin by Charlemagne;- who having repaired, beautified, and enlarged the city, which was deftroyed by the Huns in the reign of Attila in 451, made it the ufual place of his refidence. The town is feated in. a valley furrounded with mountains and woods, and yet the air is very wholefome. It may be divided into the inward and outward city. The inward is fncompaffed with a wall about three quarters of a league in circum¬ ference, having ten gates; and the outward wall, in which there are eleven gates, is about a league and a half in circumference. There are rivulets which run through the town and keep it very clean, turning fe¬ veral mills; befides twenty public fountains, and many private ones. They have- ftone-quarries in the neigh¬ bourhood, which-furnilh the inhabitants with proper materials for their magnificent buildings, of which the ftadt-houfe and the cathedral are the chief. There are likewife thirty parochial or collegiate churches. The market-place is very fpacious, and the houfes round k are ftately. In the middle, before the ftadt-houfe, is a fountain of blue ftones, which throws out- water; from fix pipes, into a marble bafon placed beneath, thirty feet in circumference. 0n the top of this foun¬ tain, is placed the ftatue of Charlemagne, of brafs, gilt; holding a fceptre in his right-hand, and a globe in his left. The ftadt-houfe is adorned with the ftatues of all the emperors fince- Charlemagne. This- fabric has three ftories, the upper of which is one entire room of 162 feet in length and'60 in breadth. In this the new-eledted emperor formerly entertained all. the elees¬ ters of the empire. Aix la chapelle is a free imperial city, and chan¬ ges its magiftracy every year on the eve of St John Baptift. The . mayor is. in the nomination-of the 3r liers, as proteftor of the city. This place is famous for feveral councils and treaties of peace concluded here; particularly thofe between France and Spain in 1668, and between Great Britain and France in 1748. The hot fulphurous waters for which this place has fo long been celebrated, arife from feveral fources, which fupply eight baths conftrufted in different parts of the town. Thefe waters near the fources are clear and pel¬ lucid ; and have a ffrong fulphureous fmell refembling the wafhings of a foul gun ; but they lofe this frrjell by expofure to air. Their tafte is faline, bitter, and uri¬ nous. They do not contain iron. They are alfo neu¬ tral near the fountain, but afterwards are manifeftly and pretty ftrongly alkaline, infomuch that clothes are waftied with them without foap.—On the vaults above the fprings and aqueducts of- thefe waters is found, e- very year, when they are opened, a quantity of fine white-coloured flowers of fulphur, which has been fub- limed from the waters^ The heat of the water of the hotteft fpring, by Dr Lucas’s account, raifes the quickfilver of Fahrenheit’s thermometer to : 36-—by Monf. Monet’s account, ,to 146—and the heat of the fountain, where they com¬ monly drink, by Dr Lucas’s, account, to 112. Dr Simmons has given the following account of their feveral temperatures, as- repeatedly obferved by himfelf with a-thermometer conftru&ed by Nairne.

The fpring ufed for drinking is in the High Street, oppofite to Charles’s bath; the heat of it at the pump is - - 1060- Dr Lucas evaporated the water of the hotteft fpring (of the Emperor’s Bath), and obtained 268 grains of folid matter from a gallon, compofed of 15 grains of calcareous earth, 10 grains of felenites, and 243 grains, of a faline matter made up of natrbn and fea fait. They are at firft naufeous and harfti, but by habit become familiar and agreeable. At firft drinking,. alfo, they generally affect the head. Their general operation is - by ftool and urine, without griping or diminution of ftfength ; ■ and they alfo -promote perfpiration. The quantity to- be drank-us^an alterative is to be varied according to-the conftitution and other circum- ftances.of the patient. In general, it is beft to begin., with a quarter or half a pint in the morning, and in-* - creafe the dofe afterwards-to, pints, as may be found convenient. The water is beft drank at the fountain,- When it, is required to purge, it IhouldBc drank in large and often-repeated draughts. In regard- to bathing, this alio muft be determined- by the age, fex; ftrength, &c. of the patient, and by the feafonr The degree of-heat of the bath fttould like* wife be confidered. The tepid ones are in general the. beft, though there are fome cafes in which the hotter, ones are moft proper. But even in thefe,. it is beft to be£ia* A K E [ 344 ] A K E begin with the temperate baths, and increafe the heat gradually. Thefe waters are efficacious in difeafes proceeding from indigeftion and from foulnefs of the ftomach and bowels. In rheumatifms; in the fcurvy, fcrophula, and difeafes of the Ikin; in hyfteric and hypochondrial diforders; in nervous complaints and melancholy; in the ftone and gravel; in paralytic complaints; in thofc evils which follow an injudicious ufe of mercury; and in many other cafes. They ought not, however, to be given in heftic cafes where there is heat and fever, in putrid diforders, or where the blood is diffolved, or the conftitution much broken down. The time of drinking, in the firft feafon, is from the beginning of May to the middle of June ; and, in the latter feafon, from the middle of Auguft to the latter end of September. There are galleries or piazzas under which the com¬ pany walk during the time of drinking, in order to promote the operation of the waters.—The poor’s bath is free for every body, and is frequented by crowds of poor people. It is fcarcely neceffary to add, that there are all kinds of amufements common to other places of public refort; but the (harpers appear more fplendid here than elfewhere, affuming titles, with an equipage fuitable to them.—Aix la Chapelle is 2 i miles from Spa, 36 from Liege, and 30 from Cologne.

AIZOON, called by Mr Miller fanper-vives though the name Aizoon has been by fome writers applied to the houfe-leek, and alfo to the aloes : A genus of the pentagynia order, belonging to the icofandria clafs of plants ; and in the natural method ranking under the 13th order, Succulent#. The characters are : The ca¬ lyx is a fingle-leaved perianthium, divided into five feg- ments, and perfiftent: There is no corolla: The Jhx- mlna confift of very numerous capillary filaments ; the antherae are fimple : The piftillum has a five-cornered germen above, with five fimple ftyli; and the ftigmata are fimple. The pericarpium is a bellied, retufe, five- cornered capfule, having five cells and five valves: The Jeeds are many and globular.—Linnaeus mentions three fpecies; the canarienfe, hifpanicum, and paniculatum. The firft is a native of the Canary iflands, the fecond of Spain, and the third of the Cape of Good Hope. They may all be raifed in this country on hot-beds; but as they are not remarkable either for beauty or any other property, it appears unneceffary to take further notice of them. AKENSIDE (Mark), a phyfician, who pub- lilhed in Latin “ ATreatife upon the Dyfentery,” in 1764, and a few pieces in the firft volume of the “ Me¬ dical TranfaCtions” of the college of phyficians, print¬ ed in 1768; but far better known, and to be diftin- guiflied chiefly hereafter, as a poet. He was born at New- caftle-upon-Tyne, November 9.1721; and after being e- ducated at the grammar-fchool in Newcaftle, was fent to the univerfities of Edinburgh and Leyden ; at which laft he took his degree of Doftor in Phyfic. He was af¬ terwards admitted by mandamus to the fame degree at Cambridge; elefted a fellow of the college of phyfi¬ cians, and one of the phyficians at St Thomas’s Ho- fpbal; and, upon the eftabliffiment of the queen’s houfe- tioid, appointed one of the phyficians to her majefty. N°9. That Dr Akenfide was able to acquire no other kind Akenfide. of celebrity than that of a fcholar and a poet, is to be L—v—'' accounted for by the following particulars in his life and conduCt, related by Sir John Hawkins.—Mr Dy- fon and he were fellow-ftudents, the one of law and the other of phyfic, at Leyden; where, being of conge¬ nial tempers, a friendftiip commenced between them that lafted through their lives. They left the univer- fity at the fame time, and both fettled in London: Mr Dyfon took to the bar, and being poffeifed of a hand- fome fortune, fupported his friend while he was endea¬ vouring to make himfelf known as a phyfician ; but in a fhort time, having purchafed of Mr Hardinge his place of clerk of the houfe of commons, he quitted Weftminfter-hall; and for the purpofe of introducing Akenfide to acquaintance in an opulent neighbourhood near the town, bought a houfe at North-End, Hamp- ftead ; where they dwelt together during the fummer- feafon, frequenting the long-room, and all clubs, and affemblies of the inhabitants. At thefe meetings, which, as they were not feleft, muft be fuppofed to have confifted of fuch perfons as ufually meet for the purpofe of goffiping, men of wealth, but of ordinary endowments, and able to talk of little elfe than news, and the occurrences of the day. Akenfide was for difplaying thofe talents which had acquired him the reputation he enjoyed in other com¬ panies : but here they were of little ufe to him; on the contrary, they tended to engage him in difputes that betrayed him into a contempt of thofe that differed in opinion from him. It was found out that he was a man of low birth, and a dependent on Mr Dyfon; cir- cumftances that furnifhed thofe whom he offended with a ground of reproach, that reduced him to the necef- fity of afferting in terms that he was a gentleman. Little could be done at Hampftead after matters had proceeded to this extremity : Mr Dyfon parted with his villa at North-End, and fettled his friend in a fmall . houfe in Bloomftmry-fquare ; affigning for his fupport fuch a part of his income as enabled him to keep a chariot.— In this new fituation Akenfide ufed every endeavour to become popular, but defeated them all, by the high opinion he everywhere manifefted of him¬ felf, and the little condefcenfion he Ihowed to men of inferior endowments; by his love of political contro- verfy, his authoritative cenfure of the public councils, and his bigotted notions rcfpefting government; fub* jefts foreign to his profeffion, and with which fome of the wifeft of it have thought it prudent not to concern themfelves. In the winter evenings he frequented Tom’s coffee-houfe in Devereux-court, then the refort of fome of the moft eminent men for learning and in¬ genuity of the time ; with fome of whom he became intangled in difputes and altercations, chiefly on fub- jefts of literature and politics, that fixed on his cha- radter the ftamp of haughtinefs and felf-conceit, and drew him into difagreeable fituations. Hence many, who admired him for his genius and parts, were ihy of becoming his intimates. The value of that precept which exhorts us to live peaceably with all men, or, in other words, to avoid creating enemies, can only be eftimated by the reflec¬ tion on thofe many amiable qualities againft which the negledt of it will preponderate. Akenfide was a man of religion and ftridt virtue ; a philofopher, a fcholar, l and A K O [ 345 ] ALA A?c«nude an(j a fjne p0et. His converfation was of the moft de- Akond h’ghtful kind ; learned, inflructive, and without any ■ < affectation of wit, cheerful and entertaining. Dr Akenfide died of a putrid fever, June 23. ! 770 ; and is buried in the parifh-chureh of St James’s, Weft- minfter. His poems, publifhed foon after his death in 4to and 8vo, confift of “ The Pleafures of Imagination,” two books of “ Odes,” a “ Hymn to the Naiads,” and fome “ Infcriptions.” “ The Pleafures of Imagina¬ tion,” his capital work, was firft publifhed in 1 744 ; and a very extraordinary production it was from a man who had not reached his 23d year. He was afterwards fenfible, however, that it wanted revifion and correc¬ tion ; and he went on reviling and corre&ing it for feveral years : but finding this tafk to grow upon his hands, and defpairing of ever executing it to his own fatisfaction, he abandoned the purpofe of correcting, and refolved to write the poem over anew upon a fome- what different and enlarged plan. He finifhed two books of his new poem, a few copies of which were printed for the ufe of the author and certain friends; of the firft book in 1757, of the fecond in 1765. He finifhed alfo a good part of a third book, and an in- trodution to a fourth; but his moft munificent and ex¬ cellent friend, conceiving all that is executed of the new work, too inconfiderable to fupply the place, and fu- perfede the republication of the original poem, and yet too valuable to be with-held from the public, hath caufed them both to be inferted in the collection of his poems. AKIBA, a famous rabbin, flourifhed a little after the deftruction of Jerufalem by Titus. He kept the flocks of a rich citizen of Jerufalem till the 40th year of his age, and then applied himfelf to ftudy in the academies for 24 years; and was afterwards one of the greateft mafters in Ifrael, he having 24,000 fcholars. He declared for the impoftor Barcochebas, -whom he owned for the Mefiiah; and not only anointed him king, but took upon himfelf the office of his mafter of the horfe. The troops which the emperor Hadrian fent againft the Jews, who under the conduct of this falfe Meffiah had committed horrid maffacres, exterminated this facffipn. Akiba 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, and his 24,000 fcholars were buried round about him'upon the fame mountain. It is imagined he invented a fuppofititious work under-the name of the patriarch Abraham. AKISSAT, the ancient Thyatira, a city in Nato- lia, in Afia, fituated in a plain 18 miles broad, which produces plenty of cotton and grain. The inhabitants, who are reckoned to be about yooo, are faid to be all Mahometans. The houfes are built of nothing but earth or turf dried in the fun, and are very low and ill contrived : but there are fix or feven mofques, which are all of marble. There are remarkable infcriptions on marble in feveral parts of the town, which are part of the ruins of ancient Thyatira. It is feated on the river Hermus, 50 miles from Pergamos. E.

Sometimes it is ufed for thofe parts of leaves otherwife called lobej, or nvirgs. ALAI (the plural number) is ufed to fignify thofe petals or leaves of papilionaceous flowers, placed be¬ tween thofe others which are called the vexillttm and carina, and which make the top and bottom of the flowers. Inftances of flowers of this ftrufture are feen in thofe of peafe and beans, in which the top leaf or petal is the vexillum, the bottom the carina, and the fide ones the alae.

Under the Romans they enjoyed aflifes, or a convention of jurifdiftion, by Pliny reckoned the fourth in order ; hence the proverb in Stephanus, expreffing their happinefs. It was built by Alabandus, whom therefore they deemed a god. The people were called Alahandi, Alabandenfes, Cicero ; and Alalandeis, after the Greek manner, in coins of Auguftus and Claudius; they were alfo called Alabandeni (Livy)‘.

Others will have it, that the name alalafler denotes the form rather than the matter Alamandtis box : In this view they define alabafter by a u_—v~ box without a handle, deriving the word from the pri¬ vative «, and anfa, handle. Alabafter is alfo faid to have been ufed for an an¬ cient liquid meafure, containing ten ounces of wine, or nine of oil. In this fenfe, the alabafter v\%s equal to half the fextary. ALABASTRUM dendroide, a kind of lamina¬ ted alabafter, beautifully variegated with the figures of ftirubs, trees, &c. found in great abundance in the pro¬ vince of Hohenftein. ALADINISTS, a feft among the Mahometans, anfwering to free-thinkers among us. ALADULIA, a confiderable province of Turky, in Afia, in that part called Natolia, between the moun¬ tains of Antitaurus, which feparate it from Amafia on the north, and from Carimania on the weft. It has TneMediterranean fea on the fouth; and the Euphrates, or Frat, on the eaft, which divides it from Diarbeker. It comprehends the Lefler Armenia of the ancients, and the eaft part of Cilicia. Formerly it had kings of its own ; but the head of the laft king was cut off by Selim I. emperor of the Turks, who had conquered the country. It is now divided into two parts: the north, comprehended between Taurus, Antitaurus, and the Euphrates, is a beglerbeglic, which bears the name of Maraih, the capital town ; and the fouth, feated be¬ tween mount Taurus and the Mediterranean, is united to the beglerbeglic of Aleppo. The country is rough, ragged, and mountainous; yet there are good paftures, and plenty of horfes and camels. The people are har¬ dy and thievifh. The capital is MaJatigah. ALAIN (Chartier), fecretary to Charles VII. king of France, born in the year 1386. He was the author of feveral works in profe and verfe; but his moft famous performance was his Chronicle of King Charles VII. Bernard de Girard, in his preface to the Hi- ftory of France, ftyles him “ an excellent hiftorian, who has^given an account of all the affairs, particulars, ceremonies, fpeeches, anfwers, and circumftances, at which he was prefent himfelf, or had information of.” Giles Coroxet tells us, that Margaret, daughter to the king of Scotland, and wife to the dauphin, puf¬ fing once through a hall where Alain lay afleep, fhe flopped and kiffed him before all the company who at¬ tended : fome of them telling her, that it was ftrange fhe fhould kifs a man who had fo few charms in his perfon, fhe replied, “ I did not kifs the man, but the .mouth from whence proceed fo many excellent fayings, fo many wife difcourfes, and fo many elegant expref- fions.” Mr Fontenelle, among his Dialogues of the Dead, has one upon this incident, between the prin- •cefs Margaret and Plato. Mr Pafquier compares Alain to Seneca, on account of the great number of beauti¬ ful fentences interfperfed throughout his writings. ALAIS, a confiderable town of France, in the province of Languedoc, fituated on the river Gardon, at the foot of the Cevennes. The Jefuits had a college in this place; and a fort was built here in 1689. It is 34 miles north of Montpellier, and 340 from Paris. E. Lon. 4. 20. N. Lat. 44. 8. ALAMANDUS (Lewis), in Yrench. Jleman, arch- bifhop of Arles, and cardinal of St Cecilia, was one of the greateft men of the fifteenth century. The cardi- Alamannf nal prefided in the council of Bafil, which depofed Eu- , H genius IV. and ele&ed the antipope Felix V. He is at”° e-j much commended by iEneas Sylvius, as a man extreme¬ ly well formed for prefiding in fuch affemblies, firm and vigorous, illuftrious by his virtue, learned, and off an admirable memory in recapitulating all that the ora¬ tors and difputants had faid. One day, when he ha¬ rangued againft the fuperiority of the pope over the council, he diftingui/hed himfelf in fuch an eminent manner, that feveral perfons went to kifs him, while others preffed- even to kifs his robe. They extolled to the Dries his abilities and genius, which had raifed him, though a Frenchman, to a fuperiority over the Italians, notwithflanding all their natural fubtlety and fineffe. There is no need of aflring, whether Pope Eugenius thundered againft the prefident of a council which depofed him. He deprived him of all his dig¬ nities, and treated him as a fon of iniquity. How¬ ever, notwithftanding this, Lewis Alamandus died in the odour of fanftity, and performed fo many miracles af¬ ter his death, that at the requeft of the canons and Celeftine monks of Avignon, and the folicitation of the cardinal of Clermont legate a latere of Clement VII. he was beatified by that pope in the year tyzy.

Albert was certainly it man of a moft curious and inquifitive turn of mind, which gave rife to other accufations brought againft him.

We are told, that Albert was naturally very dull, and fo incapable of iriftruftion, as to be upon the point of quitting the cloifter, from defpair of learning what his habit required : but that the Holy Virgin appeared to' him, and alked him in which he chofe to excel, philofophy or divinity ? that having chofen the former, fhe affured him he fhould become incomparable therein; but that, as a punifhment for not preferring divinity, he fhould fink, before he died, into his former ftupidity. It is added, that after this apparition he had an infinite deal of wit; • and that he advanced in all the fciences with fo quick a progrefs, as utterly aftoniffied his mafters : but that, three years before his death, he flopped ffiort when reading a divinity-leifture at Cologn ; and having in vain endeavoured to recal his ideas, he found that the Virgin’s prediftion was accomplifhed. “ It would be very unneceffary (fays Bayle, after relating thefe par¬ ticulars) to obferve that they are fables.

The fame debility feemed alfo to account for the into¬ lerance of the light, and for the whitenefs of the hair. “ But a learned phyfiologift, M. Blumenbach, profef- for in the univerfity at Gottingen, who has made many profound obfervations on the organs of fight, and has confidered with great attention the albinos of Chamou¬ ni, attributes their infirmity to a different caufe. “ The ftudyof comparative anatomyhas fumifhed him with frequent opportunities of obferving this pheno¬ menon ; he has found it in brutes, in white dogs, and blue ; the iris is of a very diftinft rofe-colour: the pu- in owls; he fays, it is generally to be feen in the warm- pil too, when viewed in the light, feems decidedly red; blooded animals ; but that he has never met with it in ■which feems to demonftrate, that the interior mem¬ branes are deprived of the uvea, and of that black cous matter that ftiould line them. Their hair, their' eye-brows, and eye-lalhes, the down upon their fkin, were all, in their infancy, of the moft perfect milk- thofe with cold blood. “ From his obfervations, he is of opinion, that the rednefs of the iris, and of the other internal parts of the eye, as well as the extreme fenfibility that accompanies this rednefs, is owing to the total privation of that white colour, and very fine; but their hair is now of brown or blackifh mucus, that, about the fifth week a reddifh caft, and has grown pretty ftrong. Their fight too is fomewhat {Lengthened; though they ex- aggerate to ftrangers their averfion for the light, and after conception, covers all the interior parts of the eye in its found ftate. He obferves, that Simon Pontius,. half-fhut the eye-lids, to give themfelves a more extra¬ ordinary appearance. But thofe who, like me, have feen them in their infancy, before they were tutored to this deceit, and when too few people came to Cha¬ mouni to make this affectation profitable to them, can atteft that then they were not very much offended with his treatife de Coloribus Oculorum, long ago remark¬ ed, that in blue eyes the interior membranes were lefs abundantly provided with this black mucus, and were therefore more fenfible to the a&ion of light. This fenfibility of blue eyes agrees very well, fays M. Blumenbach, with northern people, during their long twilight; while, on the contrary’, the deep black in the light of day.

It is al- learned phyfiologift fays, that it is owing to a fimila- fo 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 fame age ; and that one of their uncles maintained them out of charity, at a time of veffels contiguous to it, but contains no fat; like the dor of the fun’s beam in the torrid zone. “ As to the connexion between this red colour of: the eyes and the whitenefs of the flun and hair, the fame rity of ftrufture, confenfus ex fimilitudene fabric#.

Blumenbach was reading this memoir to the Royal Society of Gottingen, M. Buzzi, furgeon to the hofpital at Milan, an eleve of the celebrated anatomift Mofcaii, publilhed, in the 0- pufcoli Scelti de Milan, 1784, t. vii. p. 11. a very in- terefting memoir, in which he demonllrates by diffec- tion what Blumenbach had only fuppofed. A peafant of abbut 30 years of age died at the hof¬ pital of Milan of a pulmonary diforder. His body, be¬ ing expofed to view, was exceedingly remarkable by the uncommon whitenefs of the ikin, of the hair, of the beard, and of all the other covered parts of the body. M. Buzzi, who had long defired an opportunity of dif- fefting fuch a fubjeft, immediately feized upon this. He found the iris of the eyes perfeftly white, and the pupil of a rofe-colour. The eyes were diflefted with the greateft poffible care, and were found entirely def- titute of that black membrane which anatomifts call the uvea; it was not to be feen either behind the iris, or under the retina: within the eye there was only found the choroid coat extremely thin and tinged, of a pale red colour, by veflels filled with difcoloured blood. What was more extraordinary, the Ikin, when detached from different parts of the body, feemed alfo entirely divefted of the re/e mucofum: maceration did not dif- cover the leaft veftige of this, not even in the wrinkles of the abdomen, where it is molt abundant and. moll vifible. “ M. Buzzi likewife accounts for the whitenefs of the fkin and of the hair, from the abfence of the rete mu¬ cofum, which, according to him, gives the colour to the cuticle, and to the hairs that are fcattered over it. Ar mong other proofs of this opinion, he alleges a well- known faft, that if the fkin of the blackeft horfe be accidentally deflroyed in any part of the body, the hairs that afterwards grow on that part are always white, becaufe the rete mucofim which tinges thofe hairs is ne¬ ver regenerated with the fkin. “The proximate caufe of the whitenefs of albinos, and the colour of their eyes, feems therefore pretty evident¬ ly to depend on the abfence of the rete mucofum: But what is the remote caufe ? “In the firfl place, it feems probable that men affec¬ ted with this infirmity form no diflinft fpecies, for they are produced from parent^ that have dark fkins and black eyes. What is it then that deflroys the reie mu- cofum in fuch perfons ? M. Buzzi relates a fingular faft, which feems to throw fome light on this fubjeft. “A woman of Milan, named Calcagni, had fev.en fons. The two eldeil had brown hair and black eyes; the three next had white fkins, white hair, and red eyes the two lafl refembled the two eldeft. It was faid that this woman, during the three pregnancies that produ¬ ced the albinos, had a continual and immoderate appe¬ tite for milk, which fhe took in great quantities.: but that when fhe was with child of the other four chil- • dren, fhe had no fuch defire. It is not however afcer- tained, that this preternatural appetite was not itfelf the effeft of a certain heat, or internal difeafe, which deflroyed the rete mucofum in the children before they were born. ‘‘ The. albinos.of Chamouni are alfo the offspring of parents with dark fkins and black eyes. They have Albinwa- thrce fillers by the fame father and mother, who are AjI^’UJI alfo brunettes. One of them that I faw had the eyes . ^ ‘r of a dark brown, and the hair almofl black. They are faid, however, to be all afflifted with a weaknefs of fight. When the lads are married, it will be curious to obferve how the eyes of their children will be for¬ med. The experiment would be particularly decifive if they were married to women like themfelves. But this faulty conformation feems to be more rare among women than among men ; for the four of Milan, the two of Chamouni, the one defcribed by Mauperitus, the one by Helvetius, and almofl all the inflances of thefe fingular produftions, have been of our fex. It is known, however, that there are races of men and wo¬ men afiefted with this difeafe, and that thefe races per¬ petuate themfelves, in Guinea, in Java, at Panama, &c,_ “ Upon the whole, this degeneration does not feem to be owing to the air of the mountains ; for though I have traverfed the greatefl part of the Alps, and the other mountains of Europe, thefe are the only indivi¬ duals of the kind that ever I met with.” ALBINOVANUS, a Latin poet,.whom Ovid fur- named the Divine. There is now nothing of his extant, except an Elegy on Drufus, and another on the Death- of Mecsenas. ALBINUS (Bernhard Siegfred), a celebrated phy- fician and anatomifl, was born, of an illuflrious fami¬ ly, at Francfort on the Oder in 1697. His father was then profeflbr of the praftice of medicine in the univer- fity of Francfort; but in the year 1702 he repaired to Leyden, being nominated profeffor of anatomy and furgery in that univerfity. Here his fon had an oppor¬ tunity of fludying under the mofl eminent mailers in Europe, who, from the fingular abilities which he then difplayed, had no difficulty in prognoflicating his fu¬ ture eminence. But while he was diflinguifhed in every branch of literature, his attention was particularly turned to anatomy and furgery. His peculiar attach¬ ment to thefe branches of knowledge gained him the intimate friendfhip of Ruyfch and Rau, who at that time flourifhed in Leyden ; and the latter, fo juflly ce¬ lebrated as a lithotomifl, is faid to have feldom per¬ formed a capital operation without inviting him to be prefent. Having finifhed his fludies at Leyden, he went to Paris, where he attended the leftures of Du- Verney, Vaillant, and other celebrated profeffors. But he had fcarce fpent a year there, when he was invited by the curators of the univerfity of Leyden, to be a lefturer in anatomy and furgery at that place. Though, contrary to his own inclination, he complied with their requelt, and upon that occafion was created Dr of phyfic without any examination. Soon after, upon the death of his father, he was appointed to fucceed him as profeflbr of anatomy; and upon being admitted in¬ to that office on the 9th of November J72J, he deli¬ vered an oration, De vera via ad fabric# humani cor¬ poris coguitionem ducente; which was heard with uni- verfal approbation. In the capacity of a profeffor, he not only bellowed the greatefl attention upon the in- flruftion of the youth entrufted to his care, but in the improvement of the medical art. With this view, he publifhed many important difcoveries of his own ; and . by elegant editions, turned the attention of phyficians to w.orks of merit, which might othenvife have been neglefte^K ALB [ 358 ] ALB negle&ed. By thefe means his fame \ras foon extend¬ ed over Europe ; and the focieties of London, Peterf- burgh, and Harlem, cheerfully, received him as an af- fociate. In 1745, was appointed profelfor of the praftice of medicine at Leyden, and was fucceeded in the anatomical chair by his brother Frid. Bern. Al- binus. He was twice re ft or of the univerfity, and as often he refufed that high honour when it was volun¬ tarily offered him. At length, worn out by long fer- v'ice and intenfe ftudy, he died on the 9th of Septem¬ ber 1.770, in the 74th year of his age.

ALBUCA, Bastard stAr-of-Bethlehem : A genus of the monogynia order, belonging to the hex- andria clafs of plants ; and in the natural method ranking under the 10th order, CoronarLe. The cha- rafters are : The calyx is wanting : The corolla confiils of fix oval oblong petals, which are perfiftent: The fiamina con fill of fix three-fided filaments the length of the corolla : Of thefe, three are fertile, with verfatile antherie; three are barren, without antherss: The pijlillum has an oblong three-fided germen ; the ftylus is three-fided : The pericarpium is an oblong obtufe triangular capfule, having three cells and three valves: Theym/r are numerous,'flat, and incumbent. Of this genus Linnaeus reckons only two Species.- 1. The major, or liar-flower, with fpear- Ihaped leaves. This is a native of Canada, and fome other parts of North America: the root is bulbous; from whence Ihoot up eight or ten long, narrow, fpear- Ihaped leaves. In the centre of thefe arifes a flower- llem, a foot or more in height, garnifhed with a loofe fpike of greenilh yellow flowers. After the flowers are pail, the germen fwells to a three-cornered capfule, having three cells filled with flat feeds. 2. The minor, or African liar-flower, is a native of the Cape of Good Hope. This, hath alfo a pretty large bulbous root, from which arife four or five narrow awl-lhaped leaves, of a deep green colour; the flower-llem, which comes from the center of the root, is naked, and'rarely rifes more than eight or nine inches high, having five or llxgreen- ifli-yellow flowers, growing almbll in the form of an umbel at top : thefe are rarely fucceeded by feeds in Britain.

The Canada albura is hardy; fo the roots may be planted about four inches deep in a border of light earth, where they will thrive and produce their flowers late in the fummer: but as the feeds do not of¬ ten ripen in Britain, and the bulbs put out few off- fets, the plants are not common in this country. The African fort generally flowers twice a-year; firil in March or April, and again in July or Augull ; and if its roots are kept in pots filled with light earth, Ihtl- tered under a hot-bed frame, they will flower even in winter; but the bed method is to have a border in the front of a green-houfe, or Hove, where the roots of moll of the bulbous flowers may be planted in the full ground, and fereened in winter from froft : in fuch fi- tuations they'thrive much better, and flower llronger, than when kept in pots ALBUGINEA tunica, in anatomy, the third or innermoll coat or covering of the telles ; it is likewife the name given to one of the coats of the eye.

The white of an egg, according to Boerhaave, makes, an extraordinary menftruum. Being boiled hard in the fliell, and afterwards fufpended in the air by a thread, it refolves and drops down into an inf pid, fcentlefs, li¬ quor, which appears to be that anomalous unaccount¬ able menftruum fo much ufed by Paracelfus; and will, though it contain nothing ffiarp, oleaginous, or fapo- naceous, make a thorough folution of myrrh ; which is more than either water, oil, fpirits, or even fire itfelf, can effeift. A little putrid white of egg taken into the ftomach, ©ccafions a naufea, horror, fainting, vomiting, diarrhoea, and gripes ; it inflames the bile, excites heat, thirft, fe¬ ver ; and diffolves the humours like the plague. On the contrary, the white of freffi-laid eggs, if taken while warm from the hen, is extremely nourilhing to the infirm : it may be taken in luke-warm milk ; but if any other heat is applied to it, the nutritious quality will be deftroyed. The frefh white of egg prevents burns from rifing in blifters, if it is ufed immediately after the accident : it mitigates inflammations of the eyes, and preferves the face from fun-burning. In phar¬ macy, it is ufed as a medium to render balfams and tur¬ pentines, &c. mifcible with aqueous fluids; but as it difagrees with many ftomachs when thus taken, a mu¬ cilage of gum arabic may fupply its place, it being as good a medium in fimilar circumftances, and not apt to Albu- offend the tendereft ftomach.—Whites of eggs are alfo <-lue'|clu* ufeful for clarifying liquors; to which purpofe, being A|c;l_ mixed and incorporated with the liquors to be clan- —~v f fied, and the whole afterwards boiled, the whites of eggs are by this means brought together and harden¬ ed, and thus carry off the grofs parts of the liquor along with them.

ALBURNUM, the foft white fubftance which iij trees is found between the liber or inner bark and the wood, and in progrefs of time acquiring folidity, be¬ comes itfelf the wood. From its colour and compara¬ tive foftnefs, it has been ftyled by fome writers the fat of trees, adeps arborum. The alburnum is found in largeft quantities in trees that are vigorous; though in fuch as languifh, or are fickly, there is a great number of bed-s. In an oak fix inches in diameter, this fubftance is nearly equal in bulk to the wood. In a trunk of one foot diameter, it is as one to three and a half; of two and a half feet diameter, as one to four and a half, &c. but thefe pro¬ portions vary according to the health and conftitutiorv of the trees.—The alburnum is frequently gnawed in pieces by infedfs, which lodge in the fubftance, and are noirrilhed from it. ALBURNUS, in zoology, a fpeciesof the cyprinm. of Linnaeus. . See Cyprinus. ALCA, or Auk,-in ornithology, a genus of the order of anferes. The beak of this genus is without teeth, fhort, convex, compreffed, and frequently fur¬ rowed tranfverfely ; the inferior mandible is gibbous near the bafe; the feet have generally three toes. The - fpecies of the alca are 12 ; of which the moil remark¬ able are, 1. The impennis, northern penguin, or great auk,„ with a compreffed bill furrowed on each fide, and an oval fpot on each fide of tire eyes. According to Mr Martin, this bird breeds on the ifle of St Kilda ; ap¬ pearing there the beginning of May, and retiring the middle of June. It'lays one egg, which is fix inches long, of a white colour ; fome are irregularly marked -with purplifh lines croffing each other, others blotched with black, and ferruginous about the thicker end : it the egg is taken away, it will not lay another that fea- fon. Mr Macaulay informs us that it does not vifit that illand annually, but fometimes keeps aw'ay for fe- veral years together; and adds, that it lays its egg clofe to the fea-mark, being incapable, by reafon of the fhortnefs of its wings, to mount higher. The length of this bird, to the end of its toes, is three feet r but its wings are fo fmall, as to be ufelefs for flight; the length, from the tip of the longeft quill-feathers to A L C [ 360 ] A L C Alca. tlie firft joint, being only four inches and a quarter. '■J This bird is obferved by feamen never to wander be¬ yond foundings ; and according to its appearance they direct their meafures, being then aflured that land is not ' very remote. It fometimes frequents the coafts of Nor¬ way, the Ferroe ifles, Iceland, Greenland, and New¬ foundland; and feeds much on the lump-fifh, father-lafli- er, and other fiih of that fize. The young birds eat rofe- root, and other plants. The old ones are very rarely feen on Ihore, tho’ the young ones are not unfrequently met with. It is a very fhy bird. It walks ill; but dives well, and is taken in the manner ufed for the razor-bill and puffin. The fkin between the jaws is blown into a blad¬ der, and ufed for the darts of the Greenlanders, as is alfo that of fome other birds. The Ikin of the body is fuppofed to be ufed by the Efquimaux Indians for gar¬ ments. 2. The alle, little auk, or black and white diver, with a fmooth conical bill, a white ftreak on the belly and wings, and black feet. The bulk of this fpecies exceeds not that of a black-bird. It is not very common in Britain, being only met with now and then. It feems to be moll plentiful towards the north, being met with in various parts as far as Spitzbergen. It is common in Greenland, in company with the black¬ billed fpecies; feeds on the fame food ; and lays two blueilh white eggs, larger than thofe of a pigeon. It flies quick, and dives well; and is always dipping its bill into the water while fwimming or at reft on the water. It grows fat in the ftormy feafon, from the waves bringing plenty of crabs and fmall fifti within its reach ; but from its fize it is lefs fought after than the others In Greenland it is called the Ice-bird, being the harbinger of ice. This fpecies is fometimes feen of a pure white. 3. The anftica, or puffin, with a comprefied bill and four furrows ; the orbit of the eyes and temples are white. The legs of this fpecies are very fmall; and placed fo far behind as to difqualify it from Hand¬ ing, except quite eredl, refting not only on the foot, * It attends but the whole length of the leg. This circumftance* every one makes the rife of the -puffin from the ground very dif- *xus 6 ge" ^cu^t> anc^ ^ meets with many falls before it gets on wing ; but when that is effe&ed, few birds fly longer or ftronger. Thefe birds frequent the coafts of feveral parts of Great Britain and Ireland ;' but no place in greater numbers than Prieftholm ifle, where their flocks may be compared to fwarms of bees for multitude. Thefe are birds of paflage ; they refort there annually about the fifth or tenth of April, quit the place (almoft to a bird), and return twice or thrice before they fettle to burrow and prepare for ovation and incubation. They begin to burrow the firft week in May ; but fome few fave themfelves that trouble, and diflodge the rabbits from their holes, taking poffeffion of them till their departure from the ifle. Thofe which form their own burrows, are at that time fo intent on the work as to fuffer themfelves to be taken by the hand. This talk falls chiefly to the fliare of the males ; who alfo affift ■in incubation. The firft young are hatched the begin¬ ning of July. The old ones Ihow vaft affedtion to¬ wards them.; and feem totally infenfible of danger in the breeding feafon. If a parent is taken at that time, and fufpended by the wings, it will in a fort of defpair treat itfelf molt cruelly, by biting every part it can N° 9. 1 reach; and the moment it is loofed, will never offer to Alca efcape, but inftantly refort to its unfledged young: u-■nr" this affedlion ceafes at the ftated time of migration, which is moft pundlally about the nth of Auguft, when they leave fuch young as cannot fly to the mercy of the peregrine falcon, who watches the mouths of the houfe for the appearance of the little -deferted puf¬ fins, which, forced by hunger, are compelled to leave their burrows. They lay only one egg. The eggs dif¬ fer much in form : fome have one end very acute ; others have both extremely obtufe ; all are white. Their flelh is exceffively rank, as they feed on fea-weeds and filh, efpecially fprats: but when pickled and preferved with fpices, are admired by thofe who love high-eating. Dr Caius tells, that, in his days, the church allowed them in lent, inftead of fiflr: he alfo acquaints us, that they were taken by means of ferrets, as we take rabbits: at prefent, they are either dug out, or drawn from their burrow's by a hooked ftick : they bite extremely hard ; and keep fuch fall hold on whatever they faften, as not to be ealily difengaged. Their noife, when taken, is very difagreeable ; being like the efforts of a dumb per- fon to fpeak. Thefe birds are alfo common in Ire¬ land ; on the ifland Sherries, three leagues N. N. W. of Holyhead; and in the S. Stack, near Holyhead, they breed in plenty. They inhabit Iceland and Green¬ land ; and breed in the extreme part of the iflands. It is alfo found in the Ferroe ifles, where it is called Lunda; and in the Farn ifles, where it is called Coulter- neb, from the fhape of the bill. It goes alfo by vari¬ ous other names; fuch as Gulden-head, Bottle-nofe, and Helegug, in Wales; at Scarborough, Mullet; and in Cornwall, Pope. In America they are faid to frequent Carolina in winter ; and have been met with in Sand¬ wich Sound by our late voyagers: the natives ornament the fore parts and collar of their feal-fldn jackets with the beaks of them ; and thofe of Aoonalaftika wear gowns of their /kins, along with thofe of other birds. On the coaft of Kamtfchatka and the Kurulfchi iflands they are common, even on the Penfchinfki bay, almoft; as far as Ochotka: the nations of the two firft wear the bills about their necks faftened to ftraps; and, accor- . ding to the fuperftition of thefe people, their lhaman or prieft miift put them on with a proper ceremony, in order to procure good fortune. 4. The torda, or razor-bill, with four furrow's on the bill, and a white line on each fide running from the bill to the eyes. Thefe birds, in company with the guillemot, appear in our feas the beginning of Febru¬ ary ; but do not fettle on their breeding places till they begin to lay, about the beginning of May. They inr habit the ledges of the higheft rocks that impend over the fea, where they form a grotefque appearance ; fit¬ ting clofe together, and in rows one above another. They properly lay but one egg a-piece, of an extra¬ ordinary fize for the bulk of the bird, being three inches long: it is either w'hite, or of a pale fea-green, irre¬ gularly fpotted with black : if this egg is deftroyed, both the auk and the guillemot will lay another; if that is taken, then a third: they make no neft, depo- fiting their egg on the bare rock ; and though fuch multitudes lay contiguous, by a wonderful inftinct each diftinguifties its own. What is alfo matter of great amazement, they fix their egg on the fmooth rock, with fo exa£t a balance, as to fecure it from rolling off; yet ftould A L C [ fliould it be removed, and then attempted to be repla¬ ced by the human hand, it is extremely difficult, if not impoffible, to find its former equilibrium. According to Mr Latham, it is by means of a cement that the bird fixed its egg. The eggs are food to the inhabi¬ tants of the coafts they frequent; which they get with great hazard ; being lowered from above by ropes, trufting to the ftrength of their companions, whofe footing is often fo unfiable that they are forced down the precipice, and perilh together. Thefe birds are found in the north of Europe, alfo in Iceland, Green¬ land, and on the coaft of Labrador. In Europe they extend along the White Sea into the Arctic Afiatic fhores, and from thence to Kamtfchatka and the gulph ■of Ocliotka; It is the only one which reaches the inland Baltic ; being found there on the Carls-Ozar ifles, near Gothland, and the ifle of Bondon off Angermania. 5. The pica, or black-billed auk, has the bill of the fame form with the torda, but is entirely black. The cheeks, chin, .and throat, are white : in all other re- fpe£ls it agrees with the former fpecies. Mr Latham is of opinion that it is no other than the young of that fpecies. Mr Pennant obferves, that it is fometimes found on our coafts ; but, according to Mr Latham, it is in the winter-feafon only, when the common fort has quitted them. They are faid to be met with on the coaft of Candia and other parts of the Mediterra¬ nean ; “ where, no doubt (Mr Latham obferves) the complete old bird is likewife found, as I have been in¬ formed that they are common in the bay of Gibraltar, where it is curious to fee .their activity under water when purfuing the fifti; for, as the water in the bay is fometimes clear for a great depth from the furface, thefe birds may be often feen as it were flying after their prey, with all the agility of a bird in the air, turning in every direction after the fifti, with fuch wonderful addrefs and dexterity as feldom to mifs their aim.” 6. The cirrhata of Dr Pallas, or tufted auk, fome- what bigger than the common puffin, and the colours much the fame : the bill is an inch and three-quarters in length, the fame in depth at the bafe, and crolfed with three furrows : over each eye arifes a tuft of fea¬ thers four inches in length, which falls elegantly on ■each fide of the neck, reaching almoft to the back 4 and are white as far as they are attached to the head, but afterwards of a fine buff yellow : the legs are of a bright red ; the claws black. The female is princi¬ pally diftinguiftied by having the bill croffed only with two furrows inftead of three. This fpecies inhabits the ftiores of Kamtfchatka, the Kurile iflands, and thofe intervening between Kamtfchatka and America. In manners it greatly refembles the puffin ; living all day at lea, but at no great diftance from the rocks ; it comes on ftiore at night; burrows a yard •deep under ground, and makes a neft, with feathers and fea-plants; is monogamous, and lodges there the whole night with its mate. It lays one white egg, the end of May or beginning of June, which alone is thought fit to be eaten, the flefh of the bird itfelf being infipid and hard. It feeds on crabs, ftirimps, and fhell-fifli, which lull it forces from the rocks with its ftrong bill. Pal¬ las remarks, that the Kamlfchatkan girls imitate the tufts of thefe birds, which nature has fupplied them Vql. I.

The bills both of this and the common puffin >vere formerly held by the natives as a charm, and worn by the priefts as amulets ; indeed at the prefent thefe have been feen fixed round their head- dreffes, but fuppofed now to be only efteemed as mere ornaments : the flcins are however made ufe of for clothing, being fewed together. It is called in Kamt¬ fchatka, Muechagatka ; and in Ofchotka, Igilma. 7. The pfittacula, or perroquet auk, of Dr Pallas, is about the fize of the little aukv. The bill is much compreffed on the fides, in fhape convex both above and below, and of a bright red colour : from the re¬ mote corner of each eye is a very flender tuft of fine white feathers, hanging down the neck : the head and upper part of the body are dulky ; the lower whitifti, varied with black edges : the legs are of a dirty yel¬ low ; and the webs dulky. This fpecies is found at Kamtfchatka, in the ifles towards Japan, and on the weftern ffiores of America. They are fometimes feen in flocks, but feldom far from land, except driven by ftorms. Of nights they harbour in the crevices of rocks. They lay an egg almoft the fize of a hen’s, of a dirty white or yellowilh colour fpotted with brown ; which they do about the middle of June, upon the bare rock or fand, for they make no neft. Like moft of the tribe, they are ftupid birds, as may be evinced by the ridiculous method of catching them :—One of the natives places himfelf under a loofe garment of fur, of a particular make, with large open fleeves, among the rocks, at evenings when the birds, returning to their lodging-places at dufk, run under the fldrts, and up the arm-holes, for ffieiter during the night; and thus become an eafy prey. Their ftupidity likewife ■occafions them to fly aboard a ffiip at fuch times, mif- taking it for a roofting-place ; whereby navigators have been taught to avoid the danger of falling in too near with land, either of evenings, or on approaching ftorms. The eggs are efteemed good. ALCiEUS, a famous ancient lyric poet, born at Mitylene, in the ifland of Lefbos. Horace feems to think him the inventor of this kind of poefy: Now the Roman mufe infpire, And warm the fong with Grecian fire. Francis, He flourilhed in the 44th Olympiad, at the fame time with Sappho, who was likewife of Mitylene. Alcaeus was a great enemy to tyrants, but not a very brave fol- dier. He was prefent at an engagement, wherein the Athenians gained a vidlory over the Leftuans gand here, as. he himfelf is faid to have confeffed in one of his pieces, he threw down his arms, and faved himfelf by flight. Horace, who, of all the Latin poets, moft refembled Alcaeus, has made the like confeffion : With thee I faw Philippi’s plain, Its fatal rout, a fearful fcene ! And dropp’d, alas ! th’ inglorious ftiield. Where valour’s felf was forc’d to yield ; Where foil’d in dull the vanquifti’d lay, And breath’d th’ indignant foul away. Francis, The poetical abilities of Alcaeus are indifputed; and Z z though A L C [362 Alcseu?, though his writings were chiefly in the lyric ftrain, yet A1<:aics' his mufe was capable of treating the fublimelt fubjedts ~v with a fuitable dignity. Hence Horace fays, Alcsus ftrikes the golden firings, And feas, and war, and exile, fijigs. Thus while they flrike the various lyre, The ghofts the facred founds admire : But when Alaeus lifts the ftrain To deeds of war and tyrants /lain, In thicker crowds the fhadowy throng Drink deeper down the martial fong. Francis. Alcjeus, an Athenian tragic poet, and, as fome ihink, the firft compofer of tragedies. He renoun¬ ced his native country Mitylene, and paffed for an A- thenian. He left ten pieces, one of which was Pa- fiphae, that which he produced when he difputed with Ariftophanes, in the fourth year of the 97th Olympiad. There is another Alcaeus mentioned in Jftutarch, perhaps the fame whom Porphyrius mentions as a cum- pofer of fatirical iambics and epigrams, and who wrote a poem concerning the plagiarifm of Euphorus the hiftorian. He lived in the 145th Olympiad. We are told likewife of one Alc-EUs, a Meffenian, who lived in the reign of Vefpafian and Titus. We know not which of thefe it was who fuffered for his lewdnefs a very fmgular kind of death, which gave oc*- cafion to the following epitaph : ’AJkxari* rapoc &c. This is Alcseus’s tomb ; who died by a radifh,. The daughter of the earth, and punifher of Adulterers. This punifhment infiifted on adtilterers, was thrufting one of the largeft radilhes up the anus of the adulterer : or, for want of radifhes, they made ufe of a fifh with a very large head, which Juvenal alludes to : $)uofdam machos et mugilis hit rat.

ALCAICS, in ancient poetry, a denomination gi¬ ven to feveral kinds of verfe, from Alcaeus, their in¬ ventor. The firft kind confifts of five feet, viz. a fpondee, or iambic; an iambic ; a long fyllable ; a daftyle ; ano¬ ther daftyle : fuch is the following verfe of Horace, Qmnss j eo\dem cogimur, | omnium Verfa\tur ttr\nu \ferius | ocyus ] • Sors exitura. The fecond kind coqiifts of two da&yles and two tro¬ chees : as, - Exiii\um impoJi\tura) cymba. Befides thefe two, which are called dactylic Alcaics, there is another ftyled fimply Alcaic ; confifting of an epitrite; a choriambus; another choriambus ; and a bacchius: the following is of this fpecies, Cur timet Jla'yum Tiberim tan\gerc, cur \ olivum ? ] A L C Alcaic Ode, a kind of manly ode compofed of fe- Alcaic veral ftrophes, each confifting of four verfes ; the two II firft of which are always Alcaics of the firft kind ; the c^Mla‘., third verfe is a diameter hypercatalectic, or confift¬ ing of four feet and a long fyllable; and the fourth verfe is an Alcaic of the fecond kind.

The univerfity was founded by cardinal Xime- nes, archbiffiop of Toledo, about the beginning of the 16th century. The land about Alcala is watered by the Henares, well cultivated, and very fruitful, .while that at a diftance is dry and fterile : it yields grain in plenty, very good mufcat wine, and melons of a deli¬ cious kind. Without the walls is a fpring, the water of which is fo pure and fo well tafted, that it is inclo- I fed and ftuit up- for the king of Spain’s own ufe, from , | whence it is carried to Madrid.—This city is 1 o miles - fouth-weft of Guadalaxara, and 13 miles eaft of Ma¬ drid.

There is alfo an oil extracted from the berries of alcanna, and ufed in medicine as a calmer. ALCANTARA, a fmall, but very ftrong city of Eftremadura, in Spain. It gives name to one of the three orders of knighthood. It is feated on the banks of the Tajo, or Tagus, 21 miles from Coria, in a very fruitful foil, and is celebrated for its bridge over that river. This was built in the time of the emperor Ttajan, as appears by an infcription over one of the arches, by the people of Lufitania, who were affefled , to fupply the expence. It is raifed 20afeet above the level of the water; and though it confifts but of fix arches, is 670 feet in length, and 28 in breadth. At the entrance of the bridge, there is a fmall antique chapel hewn in a rock by the ancient Pagans, who de¬ dicated it to Trajan, as the Chrillians did to St Julian. This city was built by the Moors-, on account of the convenience of this bridge; which is at a place where the Tajo is very deep, running between two high fteep rocks: for this reafon, they called it Al-Cantara, which, in their language, fignifies the Bridge;. It was taken from them in 1214, and given to the knights of Cala- trava, who afterwards affumed the name of Alcantara. It was taken by the Earl of Galloway, in April, 1706, and retaken by the French in November following. It is 45 miles from Madrid, and 125 from Seville. W. Long. 7. 12. N. Lat. 39. 30.. Knights of Alcantara, a military order of Spain, which took its name from the above-mentioned city. They make a very confiderable figure in the hiftory of the expeditions againft the Moors. The knights of Alcantara make the fame vows as thofe of Calatrava, and are only diftinguifhed from them by this, that the crofs fleur de lys, which they bear over a large white cloak, is of a green colour. They poffefs 37 com- manderies. By the terms of the furrender of Alcan¬ tara to this order,, it was ftipulated, that there fhould be a confraternity between the two orders, with the fame praftices and obfervances in both ; and that the order of Alcantara fhould be fubjeft to be vifited by the grand-mafter of Calatrava. But the former foon feleafed themfelves from this engagement, on pretence that their grand-mafter had not been called-to the elec¬ tion of that of Calatrava, as had been likewife ftipula¬ ted in the articles. After the expulfion of the Moors, and the taking of Granada, the fovereignty of the or¬ der of Alcantara and that of Calatrava was fettled in the crown of Caftile by Ferdinand and Ifabella.—In 1540, the knights of Alcantara fued for leave to mar¬ ry, wliich was granted them. ALCAREZ, a fmall city of La Mancha, in Spain, defended by a pretty ftrong caftle, and remarkable for an ancient aqueduft. It Hands near the river Guarda- mena, and the foil about it is very fruitful. They have a breed , of little running-horfes, which are very fleet and ftrong. It is 25 miles north of the confines of Andalufia, 108 fouth of Cuenza, and 138 fouth by- eaft of Madrid. W.

Here is a falt-work which produces very fine white fait, from whence the town takes its name. The fields produce large quantities of a fort of rufhes, of which they make mats, which are tranfported out of the kingdom. W. Long. 9. 10. N. Lat. 38. 18. Alcassar, a city of Barbary, feated about two leagues from Larache, in Afga, a province of the king¬ dom of Fez. It was of great note, and the feat of the governor of this part of the kingdom. It was built by Jacob Almanzor, king of Fez, about the year x 180, and defigned for a magazine and place of rendezvous for the great preparations he was making to enter Granada in Spain, and to make good the footing Jo- feph Almanzor had got fame time before. It is faid his father firft invaded Spain with 300,000 men, moft of whom he was obliged to bring back to Africa to quiet a rebellion that had broke out in Morocco. This done, he returned to Spain again with an army, as is faid, of 200,000 horfe and 300,000 foot. The city is now fallen greatly to decay, fo that of fifteen mofques there are only two that they make ufe of. The reafon, probably, is the bad fituation of the toy n; for it Hands fo low, that it is exceflively hot in fummer, and almoft overflowed with water in the winter. This they affirm to be owing to a curfe of one of their faints. Here are a great number of ftorks, who live very familiarly with the people, walking about the town, pofieffing the tops of the houfes and mofques without molefta- tion; for they efteem them facred birds, and account it finful to difturb them. At prefent, the balhaw of Te- tuan appoints a governor to this town, which is the' laft of his dominions towards Mequinez. Near this city there is a high ridge of mountains, running towards Tetuan, whofe inhabitants were never brought entirely under fubjeftion; and whenever it was attempted, they revenged themfelves by infefting the roads, and robbing and deftroying the travellers. When they were purfued, they retired into their woody mountains, where none could fafely follow them. Not far from hence is the river Elmahaflen, famous for the battle fought between Don Sebaftian king of Portugal and the Moors ; in which the Portuguefe were defeated and their king flain. W.

ALCAVALA, in the Spaniffi finances, was at firft a tax of ten per cent, afterwards of fourteen per cent, and is at prefent of only fix per cent, upon the fale of every fort of property, whether moveable or im¬ moveable ; and it is repeated every time the property is fold. The levying of this tax requires a multitude of revenue-officers fufficient to guard the tranfportation of goods, not only from one province to another, but from one ffiop to another. It fubjefts not only the dealers in fome forts of goods, but thofe in all forts, every farmer, every manufacturer, every merchant and ffiopkeeper, to the continual vifits and examination of the tax-gatlierers. Through the greater part of a country in which a tax of this kind is eftabliffied, no¬ thing can be produced for diftant fale. The produce of everyr part of the country muft be proportioned to the confumption of the neighbourhood. It is to the Alcavala, accordingly, that Uftaritz imputes the ruin of the manufa&ures of Spain.

See Cervvs. ALCEA, the Holly-hock: A genus of the poly¬ which ftiould be carefully faved from thofe plants whofe Alcedo. flowers are double and of the beft colours : for though —'v" the duplicity of the flowers, as well as their colour, are only accidental properties, yet the young plants will produce nearly the fame kind of flowers with thofe from which the feeds are taken, provided no plants with Angle or bad-coloured flowers are permitted to. groiv'- near them ; and as foo'n as fueh appear they ought to, be removed from the good ones, that their farina: may not fpread into the others, which would caufe them to degenerate. The feeds ought to he gathered very dry,, and remain in their capfules until fpringj but.care muft be taken that no wet comes to them* in .winter,. other, wife the covers would turn, mouldy,-and fpoil their con¬ tents.—Theyfhould be fown in drills, about the middle of April, on a bed of light earth, and covered with earth of the fame kind about half an inch deep. When the plants have put out fix. or eight leaves, they ftiould andria order, belonging to the monodelphia clafs of be tranfplanted into nurfery-beds, obferving to water plants ; and in the natural method ranking under the 3 7th order, Columniferis. The characters are : The j;alyx is a double perianthium, monophyllous and per- fiftent; the exterior one fix-cleft, the interior half fivc- cleft: The corolla confifts of five petals, coalefced at the bafe, heait-ihaped inverfely, and expanding: The Jlamina confift of numerous filaments, coalefced below1 into a five-cornered cylinder, loofe above, and inferted into the corolla; the anthers are kidney-fhaped : The piftiUum has a roundifli germen; a fiiort cylindric ftylus; and numerous briltly ftigmata the length of the ftylus : The pericarpium confifts of many arilli,.. jointed into a verticillum about a columnar depreffed receptacle: The feeds are folitary, reniform, and deprefled. Species*- Although.Linnaeus mentions two diftinft fpecies of this. genus, vizc the rofea and ficifolia, he thinks,, that the latter may perhaps be only a va¬ riety of the former ; but Mr Miller affirms them to be diftinft fpecies, whofe difference in the form of their leaves always continues. The leaves of the firft fort are roundifli, and cut at their extremities into angles ; thofe of the fecond are deeply cut into fix or feven feg- ments, fo as to refemble a hand. Cultivation produces them until they have taken good root; after which they will require - no farther cai-e, but to keep them clean from weeds till October, when they fhould be tranfplanted where they are to remain. ALCEDO, or Kingsfisher, in ornithology, a ge¬ nus . of the order of pics. The alcedo has a long* ftrait, thick, triangular bill; with a flelhy, plain, ftiort, flat tongue. Of this genus there are a great many fpecies, vvitlv one or other of which almoft every part of the world is furniffied. Moft of them frequent rivers, and live 00 fifli, the Angularity of catching which is admirable : fometimes hovering over the wrater, where a flioal of fmall fiflies is feen playing near the furface ; at other times waiting with attention, on fome low branch hanging over the water, for the approach of a Angle one who is fo unlucky as to fwim that way ; in either cafe dropping like a ftone, or rather darting with ra¬ pidity on his prey; when, feizing it croffwife in his bill, it retires to a refting place to feaft on it; which it does piecemeal, bones and all, without referve, afterwards bringing up the indegiftible parts in pellets, like birds of prey. The wings of moft of the genus are very fhort; almoft an infinite variety of this plant, fuch as double- yet the birds fly rapidly, and with great ftrength. It flowered, fingle-flowered, deep red, pale red, blackifh red,, white, purple, yellow, and flelh-colour. The firft fpecies is a native of China, the fecond grows alfo in Iftria. Tho’ natives of warm countries, they are hardy enough to thrive in the open air in Britain, and have for many years been fome of the greateft ornaments in gardens, towards the end of fummer;, but they have the inconvenience of growings too large for fmall gardens, and requiring tall flakes to fecure them from being broken by ftrong winds. In large gardens, however, when properly difpofed, they make a fine appearance; for as their fpikes of flowers, grow very tall, there will be a fucceffion of them on the fame Items more than two months: the flowers on the lower part of the fpike ap¬ pear in July; and as their ftalks advance* new flowers are produced till near the end of September.. When planted in good ground, the ftalks will often rife to the height of eight or nine feet; fo that near fix feet of each will be garniflied with flowers, which, when double a.nd of good colours, make a very beautiful appearance. Culture-. The holly-hock is propogated by feeds. may be remarked, that throughout this genus, blue, in different ftiades, is the moft predominant colour.—The fpecies found in the South Sea Iflands are held in a kind of fuperftitious veneration by the natives of the places they feverally inhabit, perhaps on account of their be¬ ing frequently feen flying about the morais or burial- places. That which inhabits Otaheite, where it is called Erooro, is accounted particularly facred, and not allowed to be taken or killed. I. The ifpida, or common kingsfiftier, is not much larger than a fwallow; its fliape is clumfy; the bill dif- proportionably long; it is two inches from the bafe to the tip ; the upper chap black, and the lower yellow. But the colours of this bird attone for its inelegant form: the crown of the head and the coverts of the wings are of a deep blackifh green, fpotted with bright azure: the back and tail are of the moft refplendent azure; the whole under-fide of the body is orange-coloured; a broad mark of the fame paffes from the bill beyond the eyes; beyond that is a large white fpot; the tail' is Ihort, and conflils of , twelve feathers of a rich deep blue; A L C [ 365 ] A L C Akedo. blue ; the feet are of a reddifli yellow, and the three 'joints of the oUtmoft toe adhere to the middle toe, while the inner toe adheres only by one. From the diminutive fize, the flender ihort legs, and the beautiful colours of this bird, no perfon would be led to fuppofe it one of the moil rapacious little ani¬ mals that ikims the deep. Yet it is for ever on the wing, and feeds on fiih ; which it takes in furprifing quantities, when we confxder its fize and figure. It takes its prey after the manner of the ofprey, balancing itfelf at a certain diftance above the water for a confiderable fpace, then darting into the deep, and feizing the fiih with inevitable certainty. While it remains fufpended in the air, in a bright day, the plumage exhibits a beau¬ tiful variety of the moil dazzling and brilliant colours. This llriking attitude did not efcape the notice of the ancients; for Iby cus, as quoted by Athen£eus,ilyles thefe birds axxuovEx T-avutrixT^, the halcyons with expanded wings. It makes its neil in holes in the fides of the cliffs, which it fcoops to the depth of three feet; and lays from five to nine eggs, of a moil beautiful femi- tranfparent white. The female begins to lay early in the feafon, and excludes her firil brood about the be¬ ginning of April. The male, whofe fidelity exceeds even that of the turtle, brings her large provifions.of fiih while ihe is thus employed ; and ftie, contrary to moil other birds, is found plump and fat at that fea¬ fon. The male, that ufcd to twitter before this, now enters the neil as quietly and as privately as poifible. The young ones are hatched at the expiration of 20 days; but are feen to differ as well in their fize as in their beauty. This fpecies is the axxuavapav®-, or mute halcyon of Ariilotle, which he defcribea with more precifion than is ufual with that great philofopher. After his defcrip- tiOn of the bird follows that of its neil ; than which the moil inventive of the ancients have delivered no¬ thing that appears at firil fight more fabulous and ex¬ travagant. He relates, that it refembled thofe con¬ cretions that are formed by the fea-water; that it re¬ fembled the long-necked gourd; that it was hollow within; that the entrance was very narrow, fo that, faould it overfet,,the water could not enter; that it re- fiiled any violence from iron, but could be broke with a blow from the hand; and that it was compofed of the bones of the or fea-needle. The neil had medi¬ cal virtues afcribed to it;.and from the bird was called Haleyoneum. In a fabulous age, every odd fubilance that was flung aihore received that name; a fpecies of tubular coral, a fponge, a zoophite, and a mifcellane- ous concrete, having by the ancients been dignified I; *- Plin. li’-. with that title from their imaginary origin*; Yet much xxxii. c. 8 of this feems to be founded on truth.

Whoever has feen the neil of the kings- fiftier, will obferve it Itrewed with the bones and feales of fifh; the fragments of the food of the owner and its young.— On. the foundation laid by the philofopher, lueceeding writers formed other tales extremely abfurd; and the poets, indulging the powers of imagination’, dreffed the llory in all the robes of romance. This neil was a floating one : Jotcubat halcyone pendentibus aequore nidi’s. Ovid. Met. lib. xi. It was therefore neceffary to place it in a tranquil fea, Akedo. and to fupply the bird with charms to allay the fury "" " "v of a turbulent element during the time of its incubation; for it had, at that feafon, power over the feas and the winds.

It grows naturally in pafture-lands in this as well as in moft other countries in Europe. The leaves difco- ver to the tafte a moderate aftringency; and were for¬ merly much efteemed in fome female weakneffes, and in fluxes of the belly. They are now rarelymade ufe of,tho’ both the leaves and roots might douhtlefs be of fervice in cafes where mild aftringents are required. In the province of Smolandia in Gothland, they make a tinc¬ ture of the leaves, and give it in fpafmodic or convul- five difeafes. Horfes, flieep, and goats, eat it; cows are not fond of it; fwine refufe it.— 2. The alpina, or dnque-foil ladies-mantle, with finger-fhaped fawed leaves, and greenifh bloflbms. It is a native of the mountainous parts of Europe. Goats, and cows eat it ; horfes,. Iheep, and fwine, refufe it.—3. The minor, or leaft ladies-mantle, with five fmooth leaves growing at a joint, and cut into many fegments. It grows na¬ turally in Sweden, Lapland, and other cold countries. Eaten by cows and goats; refufed by horfes,. flieep, and fwine. Culture. Thefe plants have perennial roots, and an¬ nual ftalks. They are ealily propagated by parting of their roots, or fowing their feeds in autumn. They fliould have a moift foil and fhady fituation, and be kept clean from weeds ; which is all the culture they 1, require. ALCHEMIST, a practitioner in alchemy. ALCHEMY, that branch of chemiftry which had for its principal objects the tranfmutation of metals into gold ; the panacea, or univerfal remedy ; .an alka- faeft, or univerfal menftruum ; an univerfal ferment; and many other things equally ridiculous. Kircher, inftrudl"'*1’. in all the. fecrets of chemiftryj has fully expofed t..e artifices and impoftures of alche- mifts. An alchemift puts into a crucible the matter which is to be converted into gold; this hefets on the fire, blows it, ftirs it with rods ; and, after divers ope¬ rations, gold is found at the bottom of the crucible, inftead of the matter firft put in : this there are a thoufand ways of effecting, without any tranfmuta¬ tion. Sometimes it is done by dexteroufly dropping in a piece of gold concealed between the fingers, fome- times by calling in a little of the dull of gold or filver difguifed under the appearance of fome elixir, or other indifferent matter ; fometimes a crucible is ufed which has a double bottom, and gold put between the two ; fometimes the rod ufed to llir the-matter is hollow, and filled with the dull of the metal defired ; at other times there is metal mixed with the charcoal, the alhes of the furnace, or the like. . Mr Harris very properly diftinguilhes from alchemy and chemillry ; and de¬ fines the former to be ars fine arte, cujus principum ejl nentiri, medium. labor are, et finis mcndicare; and the Italians have a proverb, non ti fidiare al alchemifta po- vero 0 medico amalato. The ruin which has attended this delufion has, occafioned feveral Hates to make fe- vere laws againft pretences to alchemy. The Romans, formerly banilhed all fuch as profeffed it; and the fa- cred canons likewife dire&ed the thunder of their cen- fure againll them. Dioclefian and Casfar direded all books which treated of this fubjedl to be burnt.

ALCIAT (Andrew), a great lawyer, who flourifh- ed in the 16th century, 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 leftures and writings of lawyers ; for which Thuanus highly praifes him. He publifhed a great many law-books, and fome notes upon Tacitus. His Emblems have been much admired, and tranflated into French, Italian, and Spanifti; and feveral 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 feene of cpnfufion, The Greeks, grown infolent from their oonquefts in Perfia, turned their army againft each other, and bandied together under the conduft of the two moft opulent ftates Athens and Lacedasmon. Alcibiades, in the midft of an expedition he had planned againft the enemy of his country, was recalled home to anfwer fome charge of a private na¬ ture ; but fearing the violence of his enemy, inftead of going to Athens, he offered his fervices at Sparta, where they were readily accepted. By his advice the Lacedaemonians made a league with Perfia, which gave a very favourable turn to their affairs. But his credit in the republic railing jealdufies againft him, he pri¬ vately reconciled himfelf to his country, and took a- gain the command of an Athenian army. Here victory, waiting as it were at his command, attended all his motions. The lofs of feven battles obliged the Spar¬ tans to fue for peace. He enjoyed his triumphs, how¬ ever,..only a ftrort time at Athens. One unfuccefsfuf event made him again obnoxious to the malice of his citizens ; and he found it expedient to retire from A- thens. In his ahfence the Spartans again took the lead, and at the fatal battle of iEgos entirely fubdued the Athenian power. Alcibiades, though an exile, endea¬ voured to reftore the power of his country ; of which the Spartans having intelligence, procured him to be affaffinated. He was a man of admirable accompliflr- ments, but indifferently principled; of great parts; and of an amazing verfatility of genius. ALCINOUS, king of the Phanicians, in the ifland now called Corfu, was fon of Naufithous, and grand- fon of Neptune and Peribea. It is by his gardens this king has chiefly immortalized his memory. He re¬ ceived Ulyffes with much civility, when a ftorm had call him on his ccaft. The people here loved pleafure .- and good cheer, yet were flcilful feamen ; and Alcinous . was a good prince. . ALCMAER, a city of the United Provinces, feat* ed in North Holland, about four miles from the fea, . 15 from Haerlem, and, 18 from Amfterdam. It is a handfome city, and one of the cleaneft in Holland. The ftreets and houfes are extremely neat and regular, and the public buildings very beautiful. It had for¬ merly two parifti-churches, dedicated to St Matthew and St Lawrence. The latter had fo.high a tower, that it ferved for a fea-mark to the veffels that were in the open fea; but, in 1464, it tumbled down, and damaged the other church fa much, that they were both A L C [ 368 ] A L G Aleman both demolirtied in 1470, and one church was built in _ under the command of Frederic of Toledo, fon of the duke d’Alva, came to befiege it, after theythad taken Haerlem in 1573 ; but were forced to raife the fiege, after three months lying before it, as well on account of the infeftion of the air as the ftout refillance of the inhabitants and foldiers; even the women fignalizing themfelves bravely in its defence. It is recorded in the regifter of this city, that, in the year 1637, 120 tulips, with the off-fets, fold for 90,000 florins. The Bale accordingly calls this nunnery fpiritualium mere- Alcohol tricum canobium, “ a community of fpiritual harlots.” .

ALCOR, in aftronomy, a fmall liar adjoining to the large bright one in -the middle of the tail of urfa major.—The word is Arabic. It is a proverb among writers. He was very amorous; accounted the father the Arabians, applied to one who pretends to fee fmall of gallant poefy ; and is faid to have been the firft that introduced the cuftom of finging love-fongs in com¬ pany. He is reported to have been one of the great- eft eaters of his age ; upon which Mr Bayle remarks, that fuch a quality would have been extremely incon¬ venient, if poetry had been at that time upon fuch a footing as it has been often fince, not able to pro¬ cure the poet bread. He died of a ftrange difeafe; for he was eat up with lice. things, but overlooks much greater: Thou canjl fee Al- cor, and not yet fee the full moon. ALCORAN, or Al-koran, the feripture, or bible, of the Mahometans. The word is compounded of the Arabic particle al, and coran or Koran, derived from the verb caraa or karaa, to read. The word therefore properly fignifies, the reading; or rather, that which ought to be read. By this name the Mahometans de¬ note not only the entire book or volume of the Koran, ALCMANIAN, in ancient lyric-poetry, a kind of but alfo any particular chapter or fe&ion of it; juft as verfe confifting of two daftyles and two trochees ; as,- Virgini\bus pue\rifque | canto. The word is formed from Aleman, the name of an an¬ cient Greek poet, in great efteem for his erotics or amorous compofitions.

Befides this peculiar name, the Koran is alfo honour¬ ed with feveral appellations commca to other books of feripture : as, al Farkan, from the verb foraka, to divide or diftinguijh; not, as the Mahometan doctors fay, becaufe thofe books are divided into chapters or feftions, or diftinguifli between good and evil; but in the fame notion that the Jews ufe the word Perek, or Pirka, from the fame root, to denote a feftion or por tion of feripture. It is alfo called al Mojhaf, the vo verly in Yorklhire, and educated at Cambridge. He was lume, and al Kitah, the book, by way of eminence, which :firft -made dean of Weftminfter, and afterwards ap¬ pointed mafter of the rolls. In 1471, he was confe- cratedbifhop of Rochefter: in 1476, he was tranflated to the fee of Worcefter; and in i486, to that of Ely, 1 the room of Dr John Morton, preferred to the fee anfwers to the Biblia of the Greeks; and al Dhikr, the admonition, which name is alfo given to the Pentateuch and Gofpel. The Koran is divided into 114 larger portions of very unequal length, which we call chapters; but the Ara- of Canterbury, He was a prelate of great learning bians fowar, in the Angular Jura; a word rarely ufed and piety ; and fo highly efteemed by king Henry, -that he appointed him lord prefident of Wales, and afterwards lord chancellor of England. Alcock found¬ ed a fchool at Kingfton upon Hull, and built the fpa- cious hall belonging to the epifcopal palace at Ely. He was alfo the founder of Jefus-college in Cambridge, for a mafter, fix fellows, and as many fcholars. This houfe was formerly a nunnery, dedicated to St Radi- on any other occafion, and properly fignifying a row, order, or a regular feries; as a courfe of bricks iu building, or a rank of foldiers in an army ; and is the fame in ufe and import with the Sura, or Tora, of the Jews, who alfo call the fifty-three fedtions of the Pen¬ tateuch Scdarim, a word of the fame fignification. Thefe chapters are not, in the manufeript copies, di- ftinguiflied by their numerical order, but by particular gund: and, as Godwin tells us, the building being titles, which are taken fometimes from a particular greatly decayed, and the revenues reduced almoft to nothing, the nups had all forfaken it, except two ; whereupon bilhop Alcock procured a grant from the crown, and converted it into a college. But Cambden and others tell us, that the nuns of that houfe were fo notorious for their incontinence, that king Henry VII. and pope Julius II. confented to its difl'olution : N° 10. * matter treated, of, or perfon mentioned therein ; but ufually .from the firft word of note, exaftly in the fame manner as the Jews have named their Sedarim ; though the word from which fome chapters are denominated be very far diftant, towards the middle, or perhaps the end, of the chapter; which feems ridiculous. But the occafion of this appears to have been, that the yerfe or paflage - A L C [ 3^9 ] A L C A1, corah, pa flag e wherein-fuch ivord occurs, was, in point of time, revealed and committed to writing-before the o- ther verfes of the fame chapter which precede it in or¬ der 5 and the title being given to the chapter before it was completed, or the pillages reduced to their prefent order, the verfe from whence fuch title was taken did not always happen to begin the chapter. SoSe chap¬ ters have two or more titles, occalioned by the difference of the copies. .Some of the chapters having been revealed at Mecca,- and others at Medina, the noting this difference makes a part of the title i but the reader will obferve, that fe* veral of the chapters are faid to have been revealed part¬ ly at Mecca and partly at Medina ; and, as to others, it is yet a difpute among the commentators to which of the two places they belong. Every chapter is fubdivided into fmaller portions, of very unequal length alfo, which we ciiflomarily call verfes : but the Arabic word is ayaf, the fame with the Hebrew ototb, and figniftes fgru or wonders: fuch as are the fecrets of God, his attributes, works, judge¬ ments, and ordinances, delivered in thofe verfes; many of which have their particular titles alfo, impofed in ' the fame manner as thofe of the chapters. Befides thefe unequal divifions of chapter and verfe, the Mahometans have alfo divided their Koran into fix- ty equal portions, wdiich they call Jlhzab, in the fin- gular Hizb, each fubdivided into four equal parts; which is alfo an imitation of'the Jews, who have an ancient divifion of their Mifhma into fixty portions call¬ ed MaffiftotL But the Koran is more ufually divided into thirty feftions only, named djza, from the lingu¬ lar Joz, each of twice the length of the former, and in the like manner fubdivided into four parts-. Thefe divi¬ fions are for the ufe of the readers of the Koran in the royal temples, or in the adjoining chapels where the emperors and great men are interred. There are thir¬ ty of thefe readers belonging to every chapel, and each reads his feefion every day; fothat the whole Koran is read over once a-day. Next after the title, at the head of every chapter, except only the ninth, is prefixed the following folemn form, by the Mahometants called the Bifmallah, In THE NAME OF THE MOST MERCIFUL GOD ; which form they conftantly place at the beginning of all their books and writings in general, as a peculiar mark or diflin- guifhing charadleriftic of their religion, it being Count¬ ed a fort of impiety to omit it. The Jews, for the fame purpofe, make ufe of the form, In the name of the Lord, or. In the name of the great God ; and the ea- ftern Chriftians that of, In the name of the Father, and of the Son, and of the Holy Ghof. But Mahomet probably took this form, as he did many other things, from the Perfian Magi, who ufed to begin their books in thefe words, Benam Tezdan bakfhafhgher dadar; that is, In the name of the moft merciful juft God. There are twenty-nine chapters of the Koran, which: have this peculiarity, that they begin with certain let¬ ters of the alphabet, fome with a Angle one, others Kith'- more. Thefe letters the Mahometans believe to be the peculiar marks of the Koran, and to conceal feve- * Vol. I.

Others explain the intent of thefe letters from their na¬ ture or organ, or elfe from their value in numbers, ac¬ cording to another fpecies of the Jewilh Cabala called Gematria; the uncertainty of which conjectures fuffi- ciently appears from their difagreement. Thus, for example, five chapters, one of which is the fecond, be¬ gins with thefe letters, A. L. M. which fome imagine to Hand for Allah latiff magid, “ God is gracious and , to be glorified f or, Ana li minni, i. e. to me and from me, viz; belongs all perfection, and proceeds all good ; or elfe for Ana Allah alam, “ / am the mojl wife Gob,” taking the firft letter to mark the beginning of the firfl; word, the fecond the middle of the fecond word, and the third the laft of the third word ; or for Allah, Gabriel, Mohammed, the author, revealer, and preacher of the Koran. Others fay, that as the letter A belongs to the lower part of the throat, the firft: of the organs of fpeech ; L to the palate, the middle or¬ gan ; and M to the lips, which are the laft organ ; fo thefe letters'fignify that God is the beginning, middle, and end, or ought to be praifed in the beginning, middle, and end, of all bur words and aftions : or, as the total value of thofe three letters, in numbers, is feventy-one, they fignify, that, in the fpace of fo many years, the religion preached in the Koran (hould be fully efta- blifhed. The conjecture of a learned Chriftian is at leaft as certain as any of the former, who fuppofes thofe letters were fet there by the amanuenfis, for Amar ft Mohammed,e. ai the command of Mohammed, as the five letters prefixed to the nineteenth chapter feem to be there written by a Jewifh feribe, for Cob yaas, i. e. Thus he commanded. ' , The Koran is univerfally allowed to be written with, the utmoft elegance and purity of language, in the dia¬ led of .the tribe of Koreifh, the moft noble and polite of all the Arabians, but with fome mixture, tho’ very rarely, of other dialects. It is confefledly the ftandard of the Arabic tongue, and, as the more orthodox be¬ lieve, and are taught by the book itfelf, inimitable by any human pen (though fome feCfaries have been of another opinion), and therefore infilled on as a per manent miracle, greater than that of railing the dead, and alone fufficient to convince the wbrld of its divine original. And to this miracle did Mahomet himfelf chiefly appeal for the confirmation of his million, publicly chal¬ lenging the moft eloquent men in Arabia, which was at that time Hocked with thoufands whofe foie ftudy and ambition it was to excel in elegance of ftyle and compofition, to produce even a lingle chapter that might be compared with it (a). 3 A To (a) As the compofition and arrangement of words, however, admit of infinite varieties, it can never be ab- folutely faid that any one is the bell pofiible. In fad, Hamzah Benahmed wrote a book againft the Alcoran, with at leaft equal elegance ; and Mofelema another, which even furpaffed it, and occafioned a defedion of a great part of the Muffulmans.

To the pomp and harmony of expreflion fome aferibe all the force and effeft of the Alcoran ; which they confider as a fort of mufic, equally fitted with other fpe- cies of that art to ravifli and amaze. In this Mahomet fucceeded fo well, and fo ftrangely'captivated the minds of his audience, that feveral of his opponents thought it the effeft of witchcraft and enchantment, as he himfelf complains.—Others have attributed the effedl of the Alcoran to the frequent mention of rewards and punilh- ments; heaven and hell occurring almoft in every page. Some fuppofe, that the fenfual pleafures of paradife, fo frequently fet before the imaginations of the readers of the Alcoran, were what chiefly bewitched them. Tho’, with regard to thefe, there is a great difpute whether they are to be underftood literally or fpiritually. Se¬ veral have even allegorized the whole book. The general defign of the Koran was to unite the profeflbrs of the three different religions, then followed in the populous country of Arabia (who for the moft part lived promifeuoufly, and wandered without guides, the far greater number being idolaters, and thq veil Jews and Chriflians moftly of erroaeous and heterodox be¬ lief), in the knowledge and worfhip of one God, under the fanftion of certain laws, and the outward figns of ceremonies partly of ancient and partly of novel infti- tution, enforced by the confideration of rewards and punifhments both temporal and eternal; and to bring them all to the obedience of Mahomet, as the prophet and ambaffador cf God, who, after the repeated ad¬ monitions, promifes, and threats, of former ages, was at lafl to eltablifh and propagate God’s religion on earth, and to be acknowledged chief pontiff in fpiritual matters, as well as fupreme prince in temporal. The great doctrine then of the Koran, is the unity of God ; to reflore which point Mahomet pretended was the chief end of his miffion ; it being laid down by him as a fundamental truth, That there never was, nor ever can be, more than one true orthodox religion. For, though the particular laws or ceremonies are only temporary, and fubjedl to alteration, according to the divine diredlion ; yet the fubftance of it being eternal truth, is not liable to change, but continues immutably the fame. And he taught, that, whenever this religion became neglefted, or corrupted in effentials, God had the goodnefs to re-inform and re-admonifh mankind thereof, by feveral prophets, of whom Mofes and Je- fus were the mofl diflinguilhed, till the appearance of Mahomet, who is their feal, and no other to be expec¬ ted after him. The more effeftually to engage peo- - pie to hearken to him, great part of the Koran is em¬ ployed in relating examples of dreadful punifhments formerly inflicted by God on thofe who rejected and abufed his meffengers; feveral of which llories, or fome circumflances of them, are taken from the Old and New Teflaments, but many more from the apocry¬ phal books and traditions of the Jews and Chriflians of thofe ages, fet up in the Koran as truths in oppofition to the feriptures, which the Jews and Chriflians are charged with having altered : and indeed, few or none of the relations or circumflances in the Koran were in¬ vented by Mahomet, as is generally fuppofed, it being Cafy to trace the greatefl part of them much higher, as the reft might be, were more of thofe books extant, and was it worth while to make the inquiry. The reft of the Alcoran is taken up in preferibing neceffary laws and diredlions, frequent admonitions to moral and divine virtues, the worfhip and reverence of the Supreme Being, and refignation to his will. One of their moft learned . commentators diftinguifhes the contents of the Alcoran into allegorical and literal; under the former are comprehended all the obfeure, parabolital, and enigmatical paffages, with fuch as are repealed, or abrogated ; the latter, fuch as are clear, and in full force. The mo ft excellent moral in the whole Alcoran, in¬ terpreters fay, is that in the chapter Vll Alraf, viz., Shew mercy, do good to all, and difpute not with the ignorant; or, as Mr Sale renders it, Ufe indulgence,, command that which is juft, and withdraw far from the ignorant. Mahomet, according to the authors of the Kefchaf, having begged of the angel Gabriel a more ample explication of this paffage, received it in the fol¬ lowing terms: “ Seek him who turns thee out, give t© “ him who takes from thee, pardon him who injures, “ thee ; for God will have you plant in your fouls the “ roots of his chief perfections.” It is eafy to fee that this commentary is copied from the gofpel.—In reality, tire neceffity of forgiving enemies, though fre¬ quently inculcated in the Alcoran, is of a later date among the Mahometans than among the Chriftians;. among thofe latter, than among the heathens; and to be traced originally among the Jews. (See Exodus xxxiii. 4, 5.) But it matters not fo much who had it firft, as who obferves it beft. The caliph Haffan, fon of Hali, being at table, a flave unfortunately let fall a difli of meat reeking hot, which fealded him feverely. The flave fell on his knees, rehearfing thefe words of the Alcoran, “ Paradife is for thofe who reftrain their “ anger.” I am not angry with thee, anfwered the caliph.—“ And for thofe who forgive offences againft them,” continues the flave. I forgive thee thine, re¬ plies the caliph’—“ But above all, for thofe who return good for evil,” adds the flave. I fet thee at liberty, rejoined the caliph ; and I give thee ten dinars. There are alfo a great number of occafional paffages in the Alcoran, relating only to particular emergencies.. For this advantage Mahomet had in the piecemeal me¬ thod of receiving his revelation, that whenever he hap¬ pened to be perplexed and gravelled with any thing, he had a certain refource in fome new morfelof revelation. It was an admirable contrivance of his, to bring down the whole Alcoran at once, only to the loweft heaven,, not to earth; fince, had the whole been publifhed at once, innumerable objections would have been made, which it would have been impoffible for him to folve : but as he received it by parcels, as God faw fit they fhould be publifhed for the converfion and inftruftiom of the people, he had a fure way to anfwer all emer¬ gencies, and to extricate himfelf with honour from any difficulty which might occur.. It is the general and orthodox belief among the Maho- metants, that the Koran is of divine original; nay, that it is eternal and uncreated, remaining, as fome exprefs it, in the very effence of God: that the firft tranfeript has been from everlafting by God’s throne, written on a table of vaft bignefs', called the preferved table, in which are alfo recorded the divine decrees paft and future : that a copy from this table, in one volume on paper, was. by the miniftry of the angel Gabriel fent down to the loweft heaven, in the month of Ramadan, on the night r A L C Alcoran, of power: from whence Gabriel revealed it to Maho- by parcels, fome at Mecca, and fome at Medina, at different times, during the fpace of 23 years, as the exigency of affairs required; giving him, however, the confolation to fhow him the whole (which they tell us was bound in {ilk, and' adorned with gold and pre¬ cious ftones of paradife) once a-year ; but in the lafl Year of his life he had the favour to fee it twice. They fay, that few chapters were delivered entire, the moft part being revealed piecemeal, and written down from [ 371 1 A L C efleem and reverence among the Muflelmaris. They Alcoran, dare not fo much as touch the Alcoran without being J iirft wafhed, or legally purified; to prevent which, an infcription is put on the cover or label, Let none touch hut they •who are clean. It is read with great care and reipect; being never held below the girdle. They fwear by it ; take omens from it on all weighty occa- fions; carry it with them to war; write fentences of it in their banners; adorn it with gold and precious ftones; and knowingly fuffer it not to be in the poffeflion of any time to time by the prophet’s amanuenfis in fuch a part of a different religion; Some fay that it is punifhable of fuch and fuch a chapter, till they were completedj according to the diredfions of the angel. The firft par¬ cel that was revealed is generally agreed to have been the firft five verfes of the 96th chapter. After .the new-revealed paffages had been from the prophet’s mouth taken down in writing by his fcribe, they were publifhed to his followers; feveral of whom took copies for their private ufe, but the far greater number got them by heart. 'The originals, when re¬ turned, were put promifcuoufly into a cheft, obferving no order of time; for which reafon it is uncertain when many'paffages were revealed. When Mahomet died, he left his revelations in the fame diforder, and not digefted into the method, fuch with death, in a Chriftian, to touch it; others, that the veneration of the Muffelmans leads them to con¬ demn the tranllating it into any other language as a profanation : but thefe feem to be aggravations. The Mahometans have taken care to have their fcripture tranflated into the Perfian, the Javan, the Malayan, and other languages; tho’, out of refpedt to the origi¬ nal, thefe verfions are generally, if not always, inter- lineated. By the advocates of Mahometanifm, the Koran, as already obferved, has always been held forth as the Chrijlianhy greateft of miracles, and equally ftupendous with theand ad of raifing the dead. The miracles of Mofes and Jefus, they fay, were tranfient and temporary ; but thatl> of as it is, in which we now find them. This was the. of the Koran is permanent and perpetual; "and there- work of his fucceflbr Abu Beer; who, confidering that a great number of paflages were committed to the me¬ mory of Mahomet’s followers, many of whom were flain in their wars, ordered the whole to be collected, not only from the palm-leaves and fkins on which they had been written, and which were kept between two boards or covers, but alfo from the mouths of fuch as had gotten them by heart. And this tranfeript, when completed, he committed to the cuftody of Haffa the daughter of Omar, one of the prophet’s widows. From this relation it is generally imagined that Abu Beer was really the compiler of the Koran; though, for aught appears to the contrary, Mahomet left the chapters complete as we now have them, excepting fuch fore far furpaffes all the miraculous events of preceding ages. We will not detrad from the real merit of the Koran : we allow it to be generally elegant, and often fublime : but at the fame time we rejed with difdain its arrogant pretence to any thing fupernatural; all the real excellence of the work being eafily referable to na¬ tural and vifible caufes. “ ln the language of Arabia, a language extremely loved and diligently cultivated by the people to whom it was vernacular, Mahomet found advantages which were never enjoyed by any former or fucceeding im- poftor. It requires not the eye of a philofopher to difeover in every foil and country a principle of national pride: and if we look back for many ages on the hi- paflages as his fucceffor might add or corred from ftory of the Arabians, we fhall eafily perceive that prich thofe who had gotten them by heart; what Abu Beer among them invariably to have coniifted in the know- did elfe, being perhaps no more than to range the chapters in their prefent order, which he feems to ha'/e done without any regard to time, having generally placed the longeft firft. However, in the 30th year of the Hegira, Othman being then caliph, and obferving the great difagree- ment in the copies of the Koran in the feveral pro¬ vinces of the empire ; thofe of Irak, for example, fol¬ lowing the reading of Abu Mufa al Afhari, and the Syrians that of Macdad Ebn Afwad ; he, by the advice be tranferibed from that of Abu Beer, in Haifa’s care, under the infpedion of Zeid Ebn Thabet, Abd’allah Ebn Zobair, Said Ebn al As, and Ad’alrahman Ebn ledge and improvement of their native language. The Arabic, which has been juftly efteemed the moft copi¬ ous of the Eaftern tongues; which had exifted from the remoteft antiquity; which had been embellilhed by numberlefs poets, and refined by the conftant exercife of the natives; was the moft fuccefsful inftrument which Mahomet employed in planting his new religion among them. Admirably adapted by its unrivalled harmonv, and by its endlefs variety to add painting to expreflion, . . , . and to purfue the imagination in its unbounded flight; of the companions, ordered a great number of copies to 1t became in the hands of Mahomet an irrefiftible be tranfrnbed fmm that r>f Abn TW,- In bT,rtV<, now. charm to blind the judgment, and to captivate the fan¬ cy of his followers. “ Of that defeription of men, who firft compofed the al Hareth the Makhzumite; whom he dire&ed, that, adherents of Mahomet, and to wbom the Koran was wherever they difagreed about any word, they fhould addrefled, few, probably, were able to pafs a very ac- write it in the dialed! of the Koreilh, in which it w'as at curate judgment on the propriety of the fentiments or firft delivered. Thefe copies, when made, were dif- on the beauties of the diftion : but all could judge of period in the feveral provinces of the empire, and the the military abilities of their le'ader ; and in the midft old ones burnt and fupprefied. Though many things in Haifa’s copy were corre&ed by the abovementioned revifers, yet fome few various readings ftill occur. In fine, the book of the Alcoran is held in the higheft of their admiration it is not difficult to conceive, that they would aferibe to his compofitions every imaginary beauty of infpired language. “ Fhe ftiepherd and the foldier, though awake to the 3 A 2 charms A L C [ 372 ] A I C charms of thofe wild but beautiful compofitions, in which were celebrated their favourite occupations of love dr war, were yet little able to criticife any other works than thoie which were addreffed to their ima¬ gination or the heart. To abftraft reafonings on the attributes and the difpenfations of the Deity, to the comparative excellencies of rival religions, to the con- fiftency of any one religious fyilem in all its parts, and to the force of its various proofs, they were quite inatten¬ tive. In fuch a fituation, the appearance of a work which pofieffed fomething like wifdom and coiifiiience ; which prefcribed the rules, and illuftrated the duties of life ; and which contained the principles of a new and com¬ paratively fublime theology, independently of its real and permanent merit, was likely to excite their afto- niflrment, and to become the llandard of future com- pofition. “ In the fir ft periods of the literature of every country, fomething of this kind has happened.. The father of Grecian poetry very obvioufly influenced the tafte and imitation of his countrymen. The modern nations of Europe all poffefs fome original author, who, rifirig from the darknefs of former ages, has begun the career of compofition, and tin&ijred with the charafter of his own imagination the ftream which has flowed through Lis pofterity. “ But the prophet of Arabia had in this refpedl ad¬ vantages peculiar to himfelf. His compofitions were not to his followers the works of man, but the-.genuine language of Heaven,, which had fent him.. They were not confined therefore to that admiration which is fo liberally bellowed on the earliell produftions of genius, or to that fond attachment with which men every where regard the original compofitions of their coun¬ try: but with their admiration they blended their piety. To know and to.feel the beauties of die Koran, was in fome refpedl to lhare in the temper of heaven ; and he who was mod affedled with admiration in the peru- fal of its beauties,, feemed moll, fitly the object of that mercy which had given, it to ignorant man. The Ko¬ ran, therefore, became naturally and necelfarily - die ftandard of talle. With a language thus hallowed in their imaginations, they were too well fatisfied, either to difpute its elegance or improve its Itrufture. In fucceeding ages, the additional fandtion of antiquity, or prefcription, was given to thefe compofitions which their fathers had admiredand while the belief of its divine original continues, that admiration, which has thus become the tell and the duty of the faithful, can. Beither be altered nor diminilhed.. “ When therefore we confider thefe peculiar advan¬ tages of the Koran, we have no reafon to be furprifed at the admiration in which it is held. But if, defcend- ing to a more minute invelligation of it, we confider its perpetual inconfillence and abfurdity, vi e lhall in¬ deed, have caufe-for allcnilhment at that weaknefs of humanity which could ever have received fuch compo¬ fitions as the work of the Deitv. “ The firlt praife of all the produftiona of genius, is invention j that quality of the mind, which, by the ex¬ tent and quicknefs of its views, is capable . of. the lar- geft conceptions, and- of forming new combinations cvf obje&s the. moll diflant and unufual. But the Koran bears little imprefiion of this tranfcendent characler. Its materials are wholly borrowed fiom the JewilKand .4 Chrillian fcriptures, from the Talmudical legends and apocryphal gofpels then current in the Eall, and frcm the traditions and fables which abounded in Arabia. The materials colle&ed from thefe feveral fources arc here heaped together, with perpetual and needlef* repe¬ titions, without any fettled principleorvifibleconnectiom “ When a great part of the life of Mahomet had been fpent in preparatory meditation on the fyilem >he wa* about to ellablilh, its chapters were dealt out flowly and feparately during the long period of 23 years. Yet thus defedlive in its llrudlure, and not 1'efs exception¬ able in its doftrines, was the work which Mahomet delivered to his followers as the oracles of God.'. “ The moll prominent feature of theKoran, that point of excellence in which the partiality of its admirers has- ever delighted to view it, is the fublime notion it gene¬ rally imprefles of the nature and. attributes of God. If its author had really derived thefe. jull Conceptions from the infpiration of that Being whom they attempt to defcribe, they would not have been furrounded, as they now are on. every fide, with error and abfurdity. But.it might, eafily be proved, that whatever it jullly defines of the divine attributes,,was borrowed from ouf holy fcripture ; which even from itsfirll promulgation,, but efpecially from the completion of the New Telia-- ment,, has extended the views and enlightened the un- derjlandings of mankind; and thus furnilhcd them with arms, which have too often been ineffectually turned againll itfelf by its ungenerous enemies. “ In this initance particularly, the copy is far below the great original, both in the propriety of its images, and the force of its deferiptions. Our holy fcriptures. are the only c.ompofitions that can enable the dim fight of mortality to penetrate into the invifible world, and to behold a glimpfe of the Divine perfections. Accor¬ dingly, when they would reprefent to us the happinefs of Heaven, they defcribe it, not by any thing minute and particular, but by fomething general and great; fomething, that without defeending to any determinate object, may at onee by its beauty and immenfity ex.- cite our wilhes^and elevate our affedlions. Though in the prophetical and evangelical writings the joys that ffiall attend us in a future Hate are often mentioned, with ardent admiration, they are expreffed rather by allufion than fimilitude, rather by indefinite and figurar tive terms, than by any thing, fixed and determinate. ‘ Eye hath not feen, nor ear heard, neither have en¬ tered into the heart of man, the things which God hath prepared for them, that love him.’ 1 £V. ii. 9. What a reverence and allonilhment does this paffage excite in every heaver of talle and piety ? What ener¬ gy, and at the fame time what fimplicity, in the expref- fion? Howfublime, and at the .fame time how obfeure,. is the imagery ? “ Different was the conduct of Mahomet an his de- feriptions of heaven and of paradife. Unaffilled by the neceffary influence of virtuous intentions andDivine infpi- - ration, be was neither defirous, nor indeed able, to exalt the minds of men.to fublinw conceptions, or to ration¬ al.expedatjons. By attempting to explain what is in¬ conceivable, to defcribe what is ineffable, and to mate¬ rialize what in itfelf is fpiritual ; he ahfurdly and im- pioufly aimed to fenfualize the purity of the Divine elfence, Thus he fabricated a fyffem of incoherence, a religion .qfto.epravity, totally repugnant indeed to:the /ature.

Who is he that can intercede with him but through his good pleafure ? He knoweth that whiih is pad, and that which is to come. His throne is extended over heaven and earth, and the preferva* tion of both is to him no burden. He is the high, the mighty.’ Sale's. Kor. ii. p. 30. 4to edit. “ To this defcription who can refufe the praife of magnificence? Part of that magnificence, however, is to be referred to that verfe of the Pfalmid, whence it was borrowed, ‘ He that keepeth Ifrael, lhall neither dum¬ ber nor deep.’ Pfal. cxxi. 4. “ But if we compare it with that other paflage of the fame infpired Pfalmift, all its boafted grandeur is at once obfcured, and loll in the blaze of a greater light. “ O my God, take me not away in the midft of my days ; thy years are throughout all generations. Of ©Id had thou laid the foundations of the earth ; and the heavens are the work of thy hands. They Ihall perilh, but thou (halt endure : yea all of them Ihall wax old, as doth a garmentas a vefture lhalt thou change them, and they lhall be changed; but thou art the fame, and thy years ‘lhall not fail.’ “ The Koran, therefore, upon a retrofpe&ive view of thefe feveral circumftances, far from fupporting its arrogant claim to a fupernatural work, dnks below the level of many compofitions confeffedly of human origi¬ nal} and dill lower does it fall in our edimation, when compared with that pure and perfect pattern which we judly admire in the fcriptures of truth.- “ It is therefore abundantly apparent, that no miracle either was externally performed for the fupport, or is internally involvedinthe compofition, of the Mahometan revelation.” Alcoran, >is alfo figuratively applied to certain o- ther books full of impieties and impodures. —In this fenfe we meet with the /ilccran of the Cordeliers, which has made a great noife; wherein St Francis is extravagantly magnified, and put- on a level with Jefus Chrid. The Alcoran ,of the Cordeliers, is properly an extract of a very fcarce book, inti tied, The conformity of the life of the feraphic father St Francis with the life of Chrid, publifhed in i 5 0, 410 ; fince, at Bologna, in folio. Eralmus Albertus, being by the eltftor of Brandenburg appointed to vifit a monadery of Fran- cifcans, found this book ; and being ftruck with the extreme folly and abfurdity of it, colledted a number of curiofities out of it, and publilhed them under the title of the Alcoran of the Franeifcans, with a preface by Martin Luther. ALCORANISTS, among Mahometans, thofewho adhere dn£t?y to the letter or text of the alcoran, from an oj inioa of its ultimate fuilickncy and pcrtcction. The Perfians are generally Alcoranijls, as admitting Alcove,, the Alcoran alone for their rule of faith. The Turks,, Alcumus^ Tartars, Arabs, &c. befides the Alcoran, admit a mul- " “ v titude of traditions. The Alcoranids, among Maho¬ metans, amount to much the fame with the textuaries among the Jews. The Alcoranids can find nothing excellent out of the Alcoran ; are enemies of philofo- phers, metaphyficians, and fcholadic writers. With- them the Alccran is. every thing.

ALCUINUS (Flaccus), an ecclefiaftlc of the eighth century. Where he was born,, is a matter of difpute ; but,, according to the mod probable opinion, it was in Yorklhire. It is pretty certain, however, that he was educated at York, under the direftion of arch- bifhop Egbert, as we learn from his own letters, in which he frequently calls that great.prelate his beloved mader, and the. clergy of York the companions of his - youthful dudies. As he futvived venerable Bede about 70 years, it is hardly poffible that he could have re¬ ceived any part of his education under him, as fome writers of literary hidory have affirmed 5 and it is wor¬ thy of obfervation, that he never calls that,great man his mader, though he fpeaks of him with the highefl veneration. It is not well known to what preferments he had attained in the church before he left England, though fome fay he was abbot of Canterbury. The occalion of his leaving his native country, was his be¬ ing fent on an embafly by Offa king of Mercia to the emperor Charlemagne ; who contracted fo great an. edeem and friendffiip for him, that he earneftly folici- ted, and at length prevailed upon ihm, to fettle in his court, and became his preceptor in the fciences. Al- cuinus accordingly inftructed that great prince in rhe¬ toric, logic, mathematics, and divinity ; which ren¬ dered him one of his greateft favourites. “ He was treated with fo. much kindnefs and familiarity (fays a cotemporary writer).by the Emperor, that the other courtiers.called him, by way of eminence, the emperor's delight." Charlemagne employed bis learned favourite to write feveral books againd the heretical opinions of Felix Bifhop of Urgel in Catalonia, and-to defend the orthodox laith againd that herefiareh, in the coun¬ cil of Francfort, A. 1). #94; which he performed to the entire fatisfatiion of the Emperor and.council, ami even to the conviction of Felix and his followers, who abandoned their errors. The Emperor confultcd chiefly with Aleuinus on all things relating to religion arid learning; and, by his advice, did many great tilings for the advancement of both. An academy was edablifhed in the Imperial palace, over wdiich Al- cuinus prelided, and in which the princes and prime-’ nobility were educated; and ocher acadamits were eftabiilhed in the chief towns of Italy and France, at his. mitigation, and under his irifperition. “ France (fays one of our bed writers of literary hidory) is in- dtbied to Alcuinus for all the polite learning it bead¬ ed of in that and the following ages. The univerlities oi Fans, Tours, Fuiden, SoilLns, and many others, A L C [ 374 J A L D A'cuituis owe to him their origin and inereafe; thofe of whom II . he was not the fuperior and founder, being at lead en- lightened by his dodlrine and example, and enriched 'r~~ by the benefits he procured for them from Charle¬ magne.” After Alcuinus had fpent many years in the mod intimate familiarity with the greateft prince of his age, he at length, with great difficulty, obtained leave to retire from court to his abbey of St Martin’s at Tours. Here he kept up a conftant correfpondence , by letters with Charlemagne ; from' which it appears, that both the emperor and his learned friend were ani¬ mated with the mod ardent love to learning and reli¬ gion, and conftantly employed in contriving and exe¬ cuting the.noblefi: defigns for their advancement. He compbfed many treatifes on a great variety of fubjects, in a ftyle much fuperior in purity and elegance to that of the generality of writers in the age in which he flou- rifhed. Charlemagne often folicited him, with all the warmth of a mod affectionate friend, to return to court, and favour him with his company and advice ; but he dill excufed himfelf; and nothing could draw him horn his retirement in his abbey of St Martin in Tours, where he died A.

ALCYGN, the trivial name of a fpeciCS of alcedo. See Alcedo. ALCYONIUM, an obfolete name of a fubmarine plant. It is alfo ufed for a kind of coral, or affroites, frequently found foffile in England. AlcvoniuM Stagnum (anc. geog.), a lake in the territory of Corinth, whofe depth was unfathomable, and in vain attempted to be difcOvered by Nerct. Thro’ this lake Bacchus is faid to have defcended to hell, to Bring back Semele ; (Paufanias). ALCYONIUS (Peter), a learned Italian, whoflou- rifhed in the 16th century. He was well verfed in the 'Greek and Latin tongues, and wrote foitte pieces of eloquence which met with great approbation. He was correftor of the prefs a confiderable time for Al¬ dus Manutius, and is intitled to a fhare in the praifes given to the editions of that learned printer. He pu¬ blifhed a treatife concerning banifhment, which con¬ tained fo many fine paffages intermixed with others quite the reverfe, that it was thought he had tacked to fomewhat of his own, feveral fragments of a treatife of Cicero de gloria ; and that afterwards, in order to fave himfelf from being deteCted in this theft, he burnt the manufcript of Cicero, the only one extant. Pau- lus Manutius, in his commentary upon thefe words of Cicero, Librum tibi celeriter inittam de gloria, “ I will fpeedily fend you my treatife on gloryhas the following paffage relating to'this affair: “ He means (fays he) Kis two books On Glory, which were handed down to the age of our fathers; for Bernard Juftinian, in the index of his books, mentions Cicero de Gloria. This treatife, however, when Bernard had left his whole library to a nunnery, could not be found, though fought after with great care: nobody doubted but Pe¬ ter Alcyonius, who, being phyfician to. the nuiinery, 3 was entrufled with the library, had bafely Hole it.

There is alfo an oration afcribed to him, on the knights who died at the fiege of Rhodes. ALDBOROUGH, a fea-port town in Suffolk, wuth a market on Saturdays. It is pleafantly iituated, in a dale, between a high hill to the weftward, on which its large old-built church Hands; the fea to the eaft, and its rivet running fouth-weft. It is a large, long, ordinary town, made up of two or three ftreets of low houfes, running parallel to each other. A quar¬ ter of a mile to the fouth lies Slaughden, where they have a commodious key, with warehoufes for fifii: more foutherly itill, they have conveniences for drying their north-fea fifh. Their employment in the filhery is their chief bufinefs, which is confiderable in the feafons for cajtching herrings and fprats ; and it is the ojily place in England for curing red fprats. It is a town corpo¬ rate, and fends two members to parliament. Towards the fea, it has fome pieces of cannon planted for its de¬ fence. It is 88 miles north-eatt from London. E. Long. 1. 32. N.

ALDERHOLM, a pleafant ifland of Sweden, for¬ med by the three arms of a river running thro’ Gentle, a town of Nordland, in Sweden. Here is a wharf, a repofitory for planks and deals, two packing houfes, a large cultomhoufe for taking toll of the fhips, an arfe- nal for cannon, and a grenary. ALDERMAN, in the Britilh policy, a magiftrate fubordinate to the lord-mayor of a city or town-cor¬ porate. The number of thefe magiftrates is not limi¬ ted, but is more or lefs according to the magnitude of the place. In London they are 26 ; ,each having one of the wards of the city committed to his care. This office is for life ; fo that when one of them dies, or re* figns, a ward-mote is called, who return two perfons, one of whom the lord-mayor and aldermen choofe to fupply the vacancy. All the aldermen are juftices of the peace, by a charter of 15 Geo. II. The aldermen of London, &c. are exempted from ferving inferior offi¬ ces ; nor (hall they be put upon affizes, or ferve on ju¬ ries, lo long as they continue to be aldermen. Alderman, among our Saxon anceftors, was a de<- gree of nobility anfvvering to earl or count at prefent. Alderman was alfo ufed, in the time of king Edgar, for a judge or juftice. Thus we meet with the ALB Jtfderncy, the titles of Aldermannui totius Anglia, aldermannus Aidhe.m. regis, comitatus, civitatis, burgi, cafislli, hundredi jjvf nxsapentachii, et novemdecimorum. According to Spelman, the aldermannus totius Anglia feems to have been the fame officer who was afterwards ityled c apt ta¬ ps jujliciarius Anglia, or chief-jultice of England; the aldermannus regis feems to have been an occafional magiilrate, anfwering to our juftice of affize ; and the aldermannus comitatus, a magiftrate who held a middle rank between what was afterward called the earl and the /heriff; he fat at the trial of caufes with the bifhop: the latter proceeding according to ecclefiaftical law, and the former declaring and expounding the common law of the land. ALDERNEY, an ifland in the Britiffi channel, fub- jeft to the crown of Great Britain. It is about eight miles in compafs, and is feparated from Cape la Hogue, in_ Normandy, by a narrow ftreight, called the Race of Alderney, which is a very dangerous palfage in ftormy weather when the two currents meet; otherwife it is fafe, and has depth of water for the largeft (hips. Thro’ this ftreight the French fleet made their efcape after their defeat at La Hogue, in 1692. It is a healthy ifland, has but one church, is fruitful both in corn and pafture, and is remarkable for a fine breed of cows. The inhabitants, for their greater fafety, live together in a town of the fame name. The number of houfes are faid to be 200, and the inhabitants 1000. It has but one harbour, called Crabby, which is at a good diftance from the town; and is only fit for fmall veffels. To the weft lie the range of rocks called the Ca/kets, fo dan¬ gerous to mariners.

He is faid to have been the fon of Kenred, brother to Irta, king of the Weft- Saxons; but, in the opinion of William of Malmftmry, his father was no more than a diftant relation to the king. Having received the firft part of his education in the fchool which one Macdulf, a learned Scot, had fet up in the place where Malmlbury now Hands, he travelled into France and Italy for his improvement. At his return home, he ftudied feme time under Adrian abbot of St Auguftine’s in Canterbury, the moft learn¬ ed profeflbr of the fciences who had ever been in Eng¬ land. In thefe different feminaries he acquired a very uncommon ftock of knowledge; and became famous for his learning,, not only in England, but, in foreign countries : whence feveral learned men fent him their writings for his perufal and correction; particularly Prince Arcivil, a fon of the king of Scotland, who wrote many pieces which he fent to Aldhelm, “ in- treating him to give^ them the laft polifh, by rubbing off their Scots ruft.” He was the firft Englifhman who wrote in the Latin language, both in profe and. I, verfe, and compofed a book for the inftruCtion of his countrymen in the profody of that language. Befides this, he wrote feveral other treatifes on various fubjeCIs; fome of which are loft, and others publiftied by Martin Delrio and Canifius. Venerable Bede, who fiourifhed in the end of this and the beginning of the next cen¬ tury, gives the following character of Aldhelm : “ He was a man of univerfal erudition, having an elegant ftyle, and being wonderfully well acquainted with books, both on philofophical and religious fubjeCls.” In fa£t, tonfidering the cloud of ignorance by which he was A L D furrounded, and the great difficulty of acquiring know- Aldhtha. ledge without proper inftru&ion, Aldhelm was a very AjJ[e| extraordinary man. From one of his letters to Hedda , bilhop of Winchefter, concerning the nature of his ftu- dies whilft at Canterbury, he appears to have been indefatigably determined to acquire every fpecies of learning in his power. For a copy of this curious epiftle, fee Henry’s Hiftory, vol. ii. p. 320. King Al¬ fred the Great declared, that Aldhelm was the beft of all the Saxon poets; and that a favourite fong, which was univerfally fung in his time, near 200 years after its author’s death, was of his compofition. When he ' was abbot of Malmftury, having a fine voice, and great fkill in mufic as well as poetry, and obferving the backwardnefs of his barbarous countrymen to liften to grave inftruCtions, he compofed a number of little poems, which he fung to them after mafs in the fweet- eft manner; by which they were gradually iuftructed and civilized. After this excellent perfon had govern¬ ed the monaftery of Malmftmry, of which he was the founder, about 30 years, he was made biftiop of Shere- burn, where he died A. D. 709.—He wrote, 1. De otto vitiis principalibus. This treatife is extant in Bi- . hliotbeca Patrum of Canifius. 2. ALnigmaticum verfus mille. This, with feveral other of his poems, was. publiftied, by Martin Delrio at Mentz, 8vo, 1601. 3. A book addreffed to a certain king of Northumber¬ land, named Alfrid, on various fubjetts. 4. De vita monacborum. 5. De laude fanflorum. 6. De arithme- tica. 7. De ajlrologia. 8. A book againft the mi- ftake of the Britons concerning the celebration of Ea- fter; printed by Sonius, 1576. 9. De laude virgi- nitatis. Manufcript, in Bonnet-college, Cambridge. - Publiftied among Bede’s Opufcula. Befides many fon- nets, epiftles, and homilies in the Saxon language. ALDPORT, an ancient name for Manchefter.. See Manchester. ALDRED, abbot of Taviftock, was-promoted to the biftiopric of Worcefter in the year 1046. He was fo much in favour with King Edward the Confeffor, and had fp much power over his mind, that he obliged him to be reconciled with the worft of his enemies,.- particularly with Swane fon of the earl Goodwin, who -- had revolted againft him, and came with an army to invade the kingdom. Aldred alfo reftored the union - and friendftiip between king Edward and Griffin-kingy of Wales. He took afterwards1 a journey to Rome, and being returned into England, in the year 1054, he was fent ambaffador to the emperor Henry II.; he ftaid a whole year in Germany, and was very honour¬ ably entertained by Herman archbifhop of Cologn, from whom he learned many things relating to ecclefi¬ aftical difeipline, which on his return he eftabliftied in his own diocefs. In the year 1058 he. went to Jeru- falem, which no archbiftiop or biftiop of England had ever done before him. Two.years after he returned to-- England; and Kinfius archbiftiop of York dying the 22d of December 1060, Aldred was elefted in his Head on Chriftmas day following, and thought fit to keep his biftroprick of Worcefter with the archbiftiopric of Canterbury, as fome of his predeceffors had done. Al¬ dred went foon after to Rome, in order to receive the Pallium from the Pope: He was attended by Tofton earl of Northumberland, Gifo biftiop of Wells, and Walter biftiop of Hereford. The pope received Tof¬ ton [ 375 1 A L D [37 tfin fcry lionourably, and made him fit by him in the fynod which he held againft the Simonifts. He grant¬ ed to Gifo and Walter their requeft, becaufe they were tolerably well learned, and not accufed of limony. Bat Aldred being by his anfwers found ignorant, and guil¬ ty of fimony, the pope deprived him very feve'rely of all honoprs and dignities; fo that he was obliged to return without the Pallium. On his way home he and his three fellow-travellers were attacked by fome rob¬ bers, 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 com- paffion, of by the threatenings of the earl of Northum¬ berland, gave Aldred the Pallium ; but he was obli¬ ged to relign his bifhopric of Worcefter. However, as the archbifhopric of York had been almoft entirely ruined by the many invalions of foreigners, king Ed¬ ward gave the new archbifhop leave to keep twelve vil¬ lages or manors which belonged to the bifhopric of Worcefter. Edward the Confeffor dying in 1066, Aldred crowned Harald his fucceffor. He alfo crown- -ed 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 eftablifh and obferve righteous laws ; that he would en¬ tirely prohibit and fupprefs all rapines and unjuft judgments. He was fo much in favour with the Con¬ queror, that this prince looked upon him as a father ; and, though imperious in regard to every body elfe, he yet fubmitted to obey this archbifhop: John Bromton gives us an inftance of the king’s fubmiffion, which at the fame time fhows the prelate’s haughtinefs.— It hap¬ pened one day, as the archbifhop was at York, that the deputy-governor or lord-lieutenant going out of the city with a great number of people, met the arch* bifhop’s fervants, who came to town with feveral carts and horfes loaded with provifions. The governor afk- ed them to whom they belonged ; and they having an- fwered they were Aldred’s fervants, the governor or¬ dered that all thefe provifions fhould be carried to the king’s ftore-houfe. The archbifhop fent immediately fome of his clergy to the governor, commanding him to deliver the provifions, and to make fatisfaftion to St Peter, and to him the faint’s vicar, for the injury he had done them ; adding, that'if he refufed to comply, the archbifhop "would make ufe of his apoftolic autho¬ rity againft him, (intimating thereby that he would ex¬ communicate him). The governor, offended at this proud meffage, ufe•» ronarite. The characters are : The corolla is monope- talous, funnel-ftiaped, hexangular, much corrugated, fe- miquinquefid, and perfiftent: The Jlamina confift of fix fubulated filaments, the length of the corolla, and infert- ed into the bafe of the divifions of the corolla ; the an- theras are oblong and erect: The pijlillum has an ovate germen; the ftylus fubulated, and the length of the ftamina; the ftigma is tfifid: The pericarpium is an ovated capfule, triquetrous, pointed, and triocular The feeds are numerous. Of this genus botanical wri¬ ters enumerate five Species. 1. The farinofa, a native of Virginia, and other parts of North America. 2. The capenfis, a na¬ tive of the Cape of Good Hope. 3. The hyacinthoi- des, or Guinea aloe. 4. The zeylanica, or Ceylon aloe. 5. The fragrana, or tree-aloe, a native of Africa. Of thefe only the firft is fo hardy as to outlive the win¬ ter in Britain, unlefs placed in a ftove; and even this requires to be flickered under a frame. The flowers appear in June or July, of a whitifli green colour. The third and fifth produce fine fpikes of white flowers; thofe of the third kind appearing in July, of the fifth in March or April. By proper management the laft kind becomes a ftately plant, rifing to the height of 12 or 14 feet; the flowers open wide in the evening, and perfume the air of the ftove. Thefe fend out one or two heads, or tufts, towards their tops, which may be cut off; and after they have lain a week in the ftove to heal the wounded parts, they may be planted for in- creafe.

ALEXANDER the great, king of Macedonia.' His father Philip laid the plan of that extenfive empire, which his fon afterwards executed.—Philip, having made himfelf matter of Greece, began to call his eyes upon Perfia, with a view to retaliate upon that haughty empire the injuries of former times. It was the po¬ pular topic of the day. But this prince was cut off in the midft of his enterprife. Such, however, was the influence of Alexander in the aflembly of the Grecian ftates, that ,he was created general of their combined fbrces in the room of his father. Having made every 3 C needful [ 385 ] ALE Alexander, needful preparation, at the head of invaded Afia. The lieutenants of Darius, who was then king of Perfia, oppofed him at the river Grani- cus, where Alexander obtained a complete victory, af¬ ter which he purfued his march through Afia. At Iffus, near Scanderoon, he was met by Darius in per- fon, at the head of a prodigious army. Here he ob¬ tained a fecond viftory ; and took the camp of Darius, together with his family, whom he treated with the utmoft humanity. Contrary to all the maxims of war, inftead of purfuing Darius, he made an excurfion into Egypt; and, as far as appears, through no better mo¬ tives than thofe of vanity. Here he was acknowledged to be the fon of Jupiter Ammon. In the mean time Darius recruited his ftrength, and got together an ar¬ my fuperior to what he brought into the plain of Iffus. Alexander having finifhed his Egyptian expedition, tra- verfed Afia, and paffed the Euphrates. At Arbella, a town in Affyria, he met Darius.

He was perfedlly in the right, fays Bayle; “ for if Greece had not furnifhed him with good wri- “ ters, he would long ago have been as much forgot-> “ ten as the kings who reigned in Macedon before; “ Amphitryon.” Alexander has been praifed upon die fcore of con- tinency, yet his.life could not Turely be quite-regular; in that refpedt. Indeed, the fire of his early youth ap¬ peared fo cold towards women, that his. mother fuf- pedled him to be impotent;, and,, to fatisfy herfelf in this point, did, with the confent of Philip, procure a. very handfome courtezan to, lie with him, whofe car- reffes, however, were all to no purpofe. His behaviour tie was fought, which put all Perfia into the hands of afterwards to the Perfian captives {hows him to have had Alexander.

But thefe veterans, harraffed with the- fatigues, and feeing no end of their labour, mutinied, likewife were ali.beauties yet this young prince, who had them in his power, not only beftowed on them all the honours due to their high rank, but managed their reputation with the utmoft delicacy. They were kept as in a clayfter concealed from the world, and fecured from the reach of every diffionourable (riot only at- and refufed to march further. The difappointed chief tack,, but J imputation. He did not give the leaft han- was therefore obliged to return. At Babylon he pro- die to fcandal, either by his vilits, bis looks, or his pofed to receive ambaffadors, appoint governors, and- words: and for other Perfian dames his prifoners. fettle his vaft monarchy; but his exceffes put an end to his life in the midft of his defigns, and ’ his age. The character of this hero is fo familiar tor every bo¬ dy, that it is almoft needlefs labour to draw it. All the world knows, fays Mr Bayle, that it was equally compofed of very great virtues and very great vices. He had no^mediocrity in any thing but his ftature in his other properties, whether good or bad, he was all extremes. His ambition rofe even to madnefs. His father was not at all miftaken in fuppofing the bounds of Macedon too fmall for his fon : for how could Ma¬ cedon bound the ambition of a man, who reckoned the whole -world too fmall a dominion ? He wept at hearing the philofopher Anaxarchus fay, that there was qually beautiful in face and ffiape, he contented him- the flower of felf with faying gaily, that they gave indeed much pain to his eyes. Tfuy amazon Thaleftris could not obtain from him a compliance with her gallant requeft till after a delay of thirteen days. In the mean time, what are we to conclude from his caufing his favourite miftrefs Pancafte to be drawn naked by Apelles, the/' it is true he gave her to the painter, who fijll in love with her ? What of that immoderate love of boys,, which Athenaeus relates of him ? What of that prodi¬ gious number of wives and concubines which he kept ? His exceffes with regard to wine were notorious, and beyond all imagination ; and he committed, when drunk, a thoufand extravagancies. It was owing to wine, that he killed Clytus who faved his life, and. 1 infinite number of worlds : his tears were owing to burnt Perfepolis, one of the moft beautiful cities of his defpair of conquering them all, lince he had not the Eaft: he did this laft indeed at the indigation of yet been able to conquer, one. Livy, in a fhort di- greffion, has attempted to enquire into the events which might have happened, if Alexander, after the conqneft of Afia, had brought his arms into Italy ? Doubtlefs the courtezan Thais; but this circumftance made it. only the more heinous. It is generally believed, that he died by drinking immoderately : and even Plutarch* 'ho affeits to contradict it, owns that he did nothing things might have taken a very different turn with him; but drink the whole day he was taken ill. and all the grand projects, which fucceeded lo well a- In fhort, to firm up the character of this prince, we gainfit an effeminate Perfian monarch, might eafily have cannot be of opinion, that his good qualities did mifearried if he had to do with rough hardy Roman armies. And yet the vaft aims of this mighty con¬ queror, if feen under another point of view, may ap¬ pear to have been confined in a very narrow compafs; lince, as we are told, the utmoft wifh of that great heart, for which the whole earth was not big enough, was, after all, to be praifed by the Athenians : for it any wife compenfate for his bad ones. Heroes make a noife : their aftions glare, and ftrike the fenfes for¬ cibly ; while the infinite deftruClion and mifery they occafion lies more in the (hade, and out of fight.

He followed the profeffion of the law firft at Naples, afterwards Alexander. ALE C 387 ] ALE afterwards at Rome: but he devoted all the time he could fpare to the ftudy of polite literature; and at length he entirely left the bar, that he might lead a more eafy and agreeable life with the mufes. The par¬ ticulars of his life are to be gathered from his work in- titled Genialiuvi Dierum; We are there informed, that he lodged at Rome, in A houfe that was haunted; and he relates many furprifing particulars about the gholt: he fays alfo, that when he was very young, he went to the lectures of Philelphus, who explained at Rome the Tufculan queftions of Cicero ; he was there alfo when Nicholas Perot and Domitius Calderinus read their lectures upon Martial. The particular time when he died is not known; but he was buried in the monaftery of the Olivets. Tiraquea wrote a learned commentary upon his work, which was printed at Lyons in 1587, and reprinted at Leyden in 1673, with the notes of Dennis Godfrey, Chriflopher Colerus, and Nicholas Mercerus. ALEXANDER (Neckham), an eminent Englifh writer in the 12th and 13th centuries, born at St Al¬ bans in Hertfordfhire. In 12x5 he was made abbot of Exeter, and died in 1227. He wrote feveral works, which were never publilhed; but they are to be found in manufcript in the libraries of England and other countries. ALEXANDER (Noel) an indefatigable writer of the 17th century, born at Roan in Normandy, 1639. After finifhing his ftudies at Roan, he entered into the order of Dominican friars, and was profeffed there in 1655. Soon after he went to Paris, to go through a courfe of philofophy and divinity in the great convent, where he diftinguifhed himfelf fo, that he was appoint¬ ed to teach philofophy there, which he- did for 1 2 years. Mr Colbert fhowed him many marks of his e- fteem ; and being determined to omit nothing to per- feft the education of his fon, afterwards archbilhop of Roan, he formed an afiemly of the moft learned per- fons, whofe conferences upon ecclefiaftical hiftory might be of advantage to him. Father Alexander was in¬ vited to this affembly, where he exerted himfelf with fo much genius and ability, that he gained the parti¬ cular friendfliip of young Colbert, who fhowed him the utmoft regard as long as he lived. Thefe conferences gave rife to Alexander’s defign of'writing an eccle- fiaflical hiftory ; for, being defined to reduce what was material in thefe conferences to writing, he did it with fo much accuracy, that the learned men who compo- fed this affembly, advifed him to undertake a complete body of church-hiflory. This he executed with great affiduity, collecting and digefling the materials him¬ felf, and writing even the tables with his own hand. Fie at laft completed his work in 1686. Towards the latter part of his life, he was afflicted with the lofs of his fight; a moft inexpreffible misfortune to one whofe whole pleafure was in ftudy, yet he bore it with great patience and refigaation. He died merely of a decay of nature, 1724, in the 86th year of his age. Alexander Severus, emperor of Rome, fucceed- ed Heliogabalus about A. D. 222, when but 16 years of age.

Alexander Bilhop of Lincoln in the reigns of Henry I. and Stephen, was a Norman by birth, and nephew of the famous Roger, bifliop of Salilbury, who firft made him archdeacon of Salifbury, and afterwards, by his intereft with the king, raifed him to the mitre. Alexander was confecrated at C&nterbury, July 22. 1123. Having received his education under his uncle the bilhop of Salifbury, and been accuftomed to a fplen- •did way of living, he affefted fhow and ftate more than was fuitable to his character, or confiftent with his fortunes. This failing excepted, he was a man of worth and honour, and every way qualified for his fta- tion. The year after his confecration, his cathedral church at Lincoln having been accidentally burnt down, he rebuilt it, and fecured it againft the like accident for the future by a ftone roof. This prelate increafed the number of prebends in his church, and augmented its revenues with feveral manors and eftates. In imi¬ tation of the barons and fome of the bifhops, parti¬ cularly his uncle the bilhop of Salifbury, he built three caftles; one at Banbury, another at Sleaford, and a third at Newark. He likewife founded two mona- fteries ; one at Haverholm, for regular canons and nuns together, the other at Tame for white-friars.' He wrent twice to Rome in the years 1142 and 1144. The firft time, he came back in quality of the pope’s legate, for the calling a fynod, in which he publifhed feveral wholefome and neceflary canons. In Auguft 1147, he took a third journey to the pope, wfflo was then in France ; where he fell fick through the exceffive heat of the weather, and returning with great difficulty to England, he died in the 24th year of his prelacy. Alexander (William), earl of Stirling, an eminent Scots ftatefman and poet in the reigns of James I. and Charles I. wfflo, after travelling wuth the duke of Ar- gyle as his tutor or companion, wTote a poetical com¬ plaint of his unfucctfsful love of fome beauty, under the title of Aurora. He then removed to the court of James VI. where he applied to the more folid parts of poetry, forming himfelf upon the plan of the Greek and Roman tragedians. In 1607, he publifhed fome dra¬ matic performances, intitled The Monarchic Tragedies, dedicated to king James ; who was fo well pleafed with them, as to call him his philofophical poet. After this, he is faid to have written A fupplement to complete the third part of Sir Philip Sidney’s Arcadia; and in 1613, he produced a poem called Doovifday, or the Great Day of Judgment. He was made gentleman-ufher to prince Charles, and mafter of the requefts; was knighted; and obtained a grant of Nova Scotia, where he projected the fettlement of a colony, but afterv/ard fold it to the French. In 1626, he was made fecretary of ftate for 3 C 2 Scotland; ALE [ 388 ] ALE Alfltander Scotland; was created firft. vlfcount, and then earl, of Alexan Stirling ; and died in 1640. drettal" Alexander I. (St), whom St Ireneus reckons the tf fifth bilhop of Rome, fucceeded St Evariftus in the year 109, and died in the year 119. There is no ac¬ count of his life ; and the epiftles which are attributed to him are fuppofitious. Alexander II. king of Scotland, fucceeded his fa¬ ther William in 1213, at 16 years of age. He made an expedition into England, to oppofe the tyranny of king John ; who returned the vifit, and was offered bat¬ tle by Alexander, but refufed it. He took the city of Carlifle from Henrylll. which was afterwards exchan¬ ged for Berwick. Alexander died in 1249, in the 51ft year of his age, and 35th of his reign ; and left for his fucceffor, his ion Alexander III. who was crowned king of Scotland in j 249. The Cummings, lords of Scotland, took arms againll him; and taking him prifoner, confined him at Striveling : but he was afterwards releafed by his fnb- jedts. He married the daughter of Henry III. king of England ; and was at length killed by a, fall from his horfe, on the 10th of April 1290, after having reigned 42, or according to others 37, years. ALEXANDERS, in botany. See Smyrnium. ALEXANDREA, (anc. geog.) a mountain of Myfia, on the fea-coaft, forming a part of mount Ida, where Paris gave judgment on the three goddeffes. ALEXANDRETTA, by the Turks called Scav- deroon; a town in Syria, at the extremity of the Me¬ diterranean fea. It is the port of Aleppo, from which it is diftanc 28 or 30 leagues. It is now, properly fpeaking, nothing elfe but a village, without walls, in which the tombs are more numerous than the houfes, and which entirely owes its exiilence to the road which it commands. This is the only road, in all Syria, where veffels anchor on a foiid bottom, without their cables being liable to chafe : but in other refpedls it has many inconveniences. It is infefted, during winter, by a pecu¬ liar wind, called by the French failors k Raguier, which, rufhing from the fnowy fummits of the mountains, fre¬ quently forces ftiips to drag their anchors feveral leagues: And when the fnow begins to cover the mountains which furround the Gulph, tempeftuous winds arife which prevent veffels from entering for three or four months together. The road alfo to Aleppo by the plain is infefted by Curd robbers, who conceal themfelves in the neighbouring rocks, and frequently attack and plunder the ftrongeft caravans. But the worft circumftanee is the extreme unwholefomenefs of the air, occafioned here by ftagnant waters and mephi¬ tic exhalations. It may be affirmed, that this every year carries off one-third of the crews of the veffels which remain here during the fummer; nay, ffiips fre¬ quently lofe all their men in two months. The feafon for this epidemic diforder is principally from May to the end of September: it is an intermitting fever of the moft malignant kind ; and is accompanied with ob- ftruftions of the liver, which terminate in a dropfy. To this baneful epidemic, Alexandretta, from its fitu- ation, feems to be irremediably condemned: for the plain on which the town is built is fo low and fiat, that the rivulets, finding no declivity,can never reach the lea. When they are fwelled by the winter rains, the fea, fwelled likewife by temp efts, hinders their difeharging themfelves into it: hence their waters, forced to fpread themfelves, form lakes in the plain- On the approach of the fummer, the waters becoming corrupted by the heat, exhale vapours equally corrupt, and which can¬ not difperfe, being confined by the mountains that en¬ circle the gulph. The entrance of the bay befide's lies to the weft, which in thofe countries is the moft un¬ healthy expofure when it correfponds with 'the fea. The labour neceffary to remedy this would be immenfe, and after all infufficient; and, indeed, fuch an under¬ taking would be abfolutely impoffible under a govern¬ ment like that of the Turks. A few years ago, Mr Volney informs us, the merchants of Aleppo, difguft- ed with the numerous inconveniences of Alexandretta, wilhed to abandon that port and carry the trade to La- takia. They propofed to the Pacha of Tripoli to re¬ pair the harbour at their own expence, provided he would grant them an exemption from all duties for ten years. To induce him to comply with their requeft, the agent they employed talked much of the advantage which would, in time, refult to the whole country : “ But what fignifies it to me what may happen in time, replied the Pacha? I was yefterday at Marach; to¬ morrow, perhaps, I (hall be at Djedda: Why ftrould I deprive myfelf of prefent advantages, which are certain, for future benefits I cannot hope to partake?” The European factors were obliged therefore to remain at Skandaroon. There are three of thefe factors, two for the French, and one for the Englifh and Venetians. The only curiofity which they have to amufe ftrangers with confifts in fix or feven marble monuments, fent from England, on which you read: Here lies fuch a one, carried off in the flower of his age, by the fatal effetts of a contagious air. The fight of thefe is the more di- ftreffing, as the languid air, yellow complexion, livid eyes, and dropfical bellies of thofe who thow them, make it but too probable they cannot long efcape the fame fate. It is true, they have fome refource in the village of Bailan, the pure air and excellent waters of which furprizingly reftore the fick. The Aga, for fome years paft, has applied the duties of the cuftom- houfe of Alexandretta to his own ufe, and rendered himfelf almoft independent of the Pacha of Aleppo. The Turkifh empire is full of fuch rebels, who fre¬ quently die in peaceable poffeffion of theirmfurpations. ALEXANDRIA, now Scanderia, by Athenseus called x?Uir»; a city of Lower Egypt, and for a long time its capital. This city was built by Alexander the Great, foon after the overthrow of Tyre, about 333 years before Chrift. It is fituated on the Mediterra¬ nean, twelve miles weft of that mouth of the Nile anciently called Canopicutn; and lies in E. Long. 30.. 19. N. Lat. 31. 10. Alexander is faid to have been induced to build this city, on account of its being conveniently fituated for a fine port; and fo fudden was his refolution, that af¬ ter he had direfted where every public ftru&ure was to be placed, fixed the number of temples, and the dei¬ ties to whom they fhould be dedicated, &c. there were no inftruments at hand proper for marking out the walls, according to the cuilom of thofe times. Upon this, a workman advifed the king to collect what meal was among the foldiers, and to fift it in lines upon the ground, whereby the circuit of the walls would be fufficiently marked out. This advice was followed; A’exar. dretta Alexandria ALE [ 389 ] ALE Alexandria, and the new method of marking out the walls was, by * ~~J Ariftander, the king’s foothfayer, interpreted as a pre- fage of the city’s abounding with all the neceffaries of life. Nor was he deceived in his prediftion ; for A- lexandria foon became the ftaple, not only for merchan- dife, but alfo for all the arts and fciences of the Greeks. Alexandria was a league and a half long, by one- third in breadth, which made the circumference of its walls about four leagues. Lake Mareotis bathed its walls on the fouth, and the Mediterranean on the north. It was interfecfed lengthwife by ftraight pa¬ rallel ftreets. This direftion left a free paffage to the northerly wind, which alone conveys coolnefs and fa- lubrity into Egypt. A ftreet of 2000 feet wide be¬ gan at the gate of the fea, and terminated at the gate of Canopus. It w-as decorated by magnificent houfes, by temples, and by public buildings. In this extenfive range, the eye was never tired with admiring the marble, the porphyry, and the obeli fits, which were deftined at fome future day to embellifh Rome and Conftantinople. This ftreet, the handfomeft in the univerfe, was inter- fedfed by another of the fame breadth, which formed a fquare at their jun&ion of half a league in circumfe¬ rence. From the middle of this great place, the two gates were to be feen at once, and veffels arriving un¬ der full fail from the north and from the fouth. A mole of a mile in length flretched from the con¬ tinent to the ifle of Pharos, and divided the great har- •bour into two. That which is to the northward pre¬ ferred its name. A dyke drawn from the ifland to the rock whereon was built the Pharos, fecured it from the wefterly winds. The other was called Eunoflos^ or the Safe Return. The former is called at prefent the new, the latter the old harbour: a bridge that joins the mole to thq city, ferved for a communication between them.' It was raifed on lofty pillars funk into the fea, •and left a free pafiage for (hips. The palace, which advanced beyond the promontory of lochias, extended as far as the dyke, and occupied more than a quarter, of the city. Each of the Ptolemies added to its mag¬ nificence. It contained within its inclofure, the mu- feum, an afylum for learned men, groves, and buildings worthy of royal majefty, and a temple where the body ©f Alexander was depofited in a golden coffin. The infamous Seleucus Cibyofactes violated this monument, carried off the golden coffin, and put a glafs one in its place. In the great harbour was the little ifland of Anti-Rhodes, where Hood a theatre, and a royal place of refidence. Within the harbour of Eunoftc s was a fmaller one, called Kjbotos, dug by the hand of man, which communicated with Lake Mareotis by a canal. Between this canal and the palace was the admirable temple of Serapis, and that of Neptune near the great place where the market was held.' Alexandria extend¬ ed likewife along the fonthern banks of the lake. Its eaftertt part prefented to view the gymnafium, with its porticoes of more than 600 feet long, fupported by fe- veral rows of marble pillars. Without the gate of Ca¬ nopus was a fpacious circus for the chariot races. Be¬ yond that, the fuburb of Nicopolis ran along the fea- fhore, and fee me d a fecond Alexandria. A fuperb amphitheatre was built there with a race-ground, for the celebration of the quinquennalia. Such is the defeription left us of Alexandria by the ancients, and above all by Strabo.. The architeft employed by Alexander in this un- A’t-randra, dertaking was the celebrated Dinocrates, who had —-v—J acquired fo much reputation by rebuilding the temple of Diana at Ephefus. The city was firft rendered populous by Ptolemy Soter, one of Alexander’s cap¬ tains, who, after the death of the Macedonian monarch, being appointed governor of Egypt, form affumed the title of king, and took up his refidence at Alexandria, about 304 years before Chrift. In the 30th year of Ptolemy Spter’s reign, he took his fon Ptolemy Philadelphus partner with him in the empire ; and by this prince the city of Alexandria was much embellifhsd. In the firft year of his reign the famous watch-tower of Pharos was finifhed. It had been begun feveral years before by Ptolemy Soter; and, when finifhed, was looked upon as one of the wonders of the world. The fame year, the ifland of Pharos itfelf, originally feven furlongs diftant from the continent, was joined to it by a caufeway. This was the work of Dexiphanes, who completed it at the fame time that his fon put the laft hand to the tower. The tower was a large fquare ftruclure of white marble ; on the top of which fires were kept conftantly burning, for the direction of failors. The building coft 800 talents ; which, if Attic, amounted to L. ] 65,000 ; if Alexandrian, to twice that fum. The architect employed in this famous ftrufture fell upon the following contrivance to ufurp the whole glory to himfelf. — Being ordered to engrave upon it the following infeription, “ King Ptolemy to the Gods the Saviours, for the benefit of Sailorsinftead of the king’s name he fubftituted his own, and then filling up the hollowof the marble with mortar, wrote upon it the above mentioned infeription. In proeefs of time, the mortar being wore off, the following in¬ feription appeared: “ Sostratus the Cnidian, the fon of Dexiphanes, to the Gods the Saviours, for the benefit of Sailors.” This year alfo was remarkable for the bringing of the image of Serapis from Pontus to Alexandria. It was fet up in one of the fuburbs of the city called Rhacotis, where a temple was afterwards erected to his honour, fuitable to the greatnefs of that (lately me¬ tropolis, and called, from the god worshipped there, Serapeum. This ftruclure, according to Ammianus Marcellinus, furpaffed In beauty and magnificence all others in the world, except the capitol at Rome. ——— Within the verge of this temple was the famous Alex¬ andrian library. It was founded by Ptolemy Soter, for the ufe of an academy he inftituted in this city ; and,by continual additions by his fucceffors, became at laft the fined library in the world, containing no fewer than ; 700,000 volumes. The method followed in collecting books for this library, was, to feize allthofe which were brought into Egypt by Greeks or other foreigners. The books were tranferibed in the mufeum- by perfons . appointed for that purpofe; the copies were then deli¬ vered to the. proprietors, and the originals laid up in the library. Ptolemy Euergetes, having borrowed from the Athenians the works of Sophocles, Euri¬ pides, and riEfchylus, returned them only the copies,. which he caufed to be tranferibed in as beautiful a. manner as poffible^ prefenting the Athenians at the fame time with fifteen talents (upwards of L. 3000. Sterling) for the exchange.. Aa ALE I 39° 3 ALE Alexandrl'a. As" the mufeum was at firft in that quarter oi the 1 v~*~' city called Brucbim, near the royal palace, the library was placed there likewife ; but when it came to con¬ tain 400,000 volumes, another library, within the -Serapeum, was erefted by way of fupplement to it, and on that account called the daughter of the former. In this fecond library 300,000 volumes, in procefs of time, were depoiited ; and the two together contained •the 700,000 volumes already mentioned. In the war carried on by Julius Casfar again!! the inhabitants of this city, the library in the Bruchion, with the 400,000 volumes it contained, was reduced to a!hes. The li¬ brary in the Serapeum, however. Hill remained; and here Cleopatra depofited 200,000 volumes of the Per- gamean library, which Marc Antony prefented her with. Thefe, and others added from time to time, rendered the new library at Alexandria more nume¬ rous and confiderable than the former ; and though it was often plundered during the revolutions and troubles of the Roman empire, yet it was again and again re¬ paired, and filled with the fame number of books. For 293 years Alexandria was held in fubjedlion by the Ptolemies. Here is a lift of thefe princes, with the dates of their refpeftive reigns. Ptolemy the fon of Lagus, furnamed Soter, reigned 39 years, and died in the year of the world 3720. Ptolemy Philadelphus reigned 39 years, and died in 3758. Ptolemy Euergetes reigned 25 years, and died in 3783. Ptolemy Philopator reigned 17 years, and died in 3800. Ptolemy Epiphanes reigned 24 years, and died in 3824. Ptolemy Philometor reigned 37 years, and died in 3861. Ptolemy Euergetes, or Phyf- con, reigned 53 years, part with his brother Philome- ter and part alone. He died in 3888. Ptolemy La- thyrus reigned 36 year® fix months. He died in 3923. Cleopatra, the daughter of Lathyrus and wife of A- lexander I. reigned fix months. Alexander L the ne¬ phew of Lathyrus, was eftabliihed in 3924 and died in 3943. Alexander II. the fon of Alexander I. was difpoffeffed by the Alexandrians in 3939. Ptolemy Nothus, or Auletes, the fen of Lathyrus, reigned 1 3 years, and died in 3953. Ptolemy, furnamed Z)/^- Jius or Bacchus, reigned three years eight months, and died in 3957. Cleopatra reigned from 3957, and kill¬ ed herfelf in 3974. This city, as we have already obferved, foon became extremely populous, and was embelliflied both by its own princes and the Romans ; but, like moft other noted cities of antiquity, hath been the feat of terrible maflacres. About 141 years before Chrift, it was al- moft totally depopulated by Ptolemy Phyfcon. That barbarous monfter, without the leaft provocation, gave free liberty to his guards to plunder his metropolis and murder the inhabitants at their pleafure. The cruel¬ ties praftifed on this occafion cannot be exprefied; and the few who efcaped were fo terrified that they fled into other countries. Upon this, Phyfcon, that he might not reign over empty houfes, invited thither ftrangers from the neighbouring countries ; by whom the city was repeopled, and foon recovered its former fplendor. On this occafion many learned men having been obliged to fly, proved the means of reviving learn¬ ing in Greece, Afia Minor, the iflands of the Archi¬ pelago, and other places, where it was almoft totally loft. The new inhabitants were not treated with much Verandrii. more kindnefs by Phyfcon than the old ones had been } ——v~ for, on their complaining of his tyrannical behaviour, he refolved on a general maffacre of the young men. Accordingly, when they were one day affembled in the gymnafium, or place of their public exercifes, he or¬ dered it to be fet on fire ; fo that they all perilh- ed, either in the flames, or by the fwords of his mer¬ cenaries, whom the tyrant had placed at all the ave¬ nues. Though Julius Casfar was obliged to carry on a war for fome time again!! this ’city, it feems not to have fuffered much damage, except the burning of the library already mentioned. Before Ctefar left Alexandria, in acknowledgment of the alfiftance he had received from the Jews, he confirmed all their privileges there, and even engraved his decree on a pil¬ lar of brafs. This, however, did not prevent the maf¬ facre of 50,000 of them in this city about the year of Chrift 67. The city of Alexandria feems to have fallen into de¬ cay foon after this, and to have forfeited many of its ancient privileges, tho’ for what offence is not known ; but when Adrian vifited Egypt, about the year 141, it was almoft totally ruined. He repaired both the public and private buildings, not only reftoring the inhabitants to their ancient privileges, but heaping new favours upon them 5 for wdiich they returned him their folemn thanks, and conferred upon him what honours they could while he was prefent; but as foon as he was gone, they publilhed the moll bitter and virulent lam¬ poons again!! him. The fickle and fatirical humour of the Alexandrians was highly difliked by Adrian, though he inflidled no puniflrment upon them for it; but when they lampoon¬ ed Caracalla, he did not let them efcape fo eafily. That tyrant, in the year 215, when he vifited their city, having become the fubjedl of their fooliflr fatires, ordered a general maffacre by his numerous troops, who were difperfed all over the city. The inhuman orders . ? being given, all were murdered, without diftinction of age or fex; fo that in one night’s time the whole city floated in blood, and every houfe was filled with car- cafes. The monfter w ho occafioned this had retired during the night to the temple of. Serapis, to implore the protection of that deity ; and, not yet fatiated with flaughter, commanded the maffacre to be continued all the next day; fo that very few of the inhabitants remain¬ ed. As if even this had not been fufficient, he ftripped the city of all its ancient privileges ; fuppreffed the aca¬ demy ; ordered all ftrangers who lived there to depart; and that the few who remained might, not have the fa- tisfa&ion of feeing one another, he cut off all commu¬ nication of one ftreet with another, by walls built for that purpofe, and guarded by troops left there. Notwjthftanding this terrible difafter, Alexandria foon recovered its former fplendor, as Caracalla was murdered afliort time after. It was long efteemed the fir!! city in the world, next to Rome ; and we may judge of its magnificence, and the multitude of people con¬ tained in it, from the account of Diodorus Siculus, who relates, that in his time (44 years before Chrift) Alexandria had on its rolls 300,000 freemen. To¬ wards the middle of the fixth century, Amrou Ebn el alas, Omar’s general, took it by ftorm, after a liege ALE Alexandria.of 14 months, and with the lofs of 23,000 men. He- radius, then emperor of Conftantinople, did not fend a fingle ihip to its affiftance. This prince affords an example very rare in hiftory ; he had difplayed fome vigour in the firft year of his reign, and then fuffered himfelf to be lulled into idlenefs and effeminacy. A- wakened fuddenly from his lethargy by the noife of tiie conqueits of Cofroes, that fcourge of the eaft, he put hhnfelf at the head of his armies, diftinguifhed himfelf as a great captain from his very nrfl campaign, laid wafte Perfia for feven years, and returned to his capital covered with laurels : he then became a theo- lo pan on the throne, loft all his energy, and amufed himfelf the reft of his life with difputing upon Mono- theifm, whilft the Arabs were robbing him of the finefl provinces of his empire. Deaf to the cries of the un¬ fortunate inhabitants of Alexandria, as he had been to thofe of the people of Jerufaiem, who defended them- felves for two years, he left them a facrifiee to the for¬ tunate afcendant of the indefatigable Amrou. All their intrepid youth periftied with their arms in their hands. The victor, aftonilhed at his conqueft, wrote to the caliph, “ I have taken the city of the w^eft. It is of an immenfe extent. I cannot defcribe to you how many winders it contains. There are 4000 palaces, 4000 baths, 12,000 dealers in freih oil, 12,000 gar¬ deners, 40,000'Jews who pay tribute, 400 come¬ dians,” &c. At this time, according to the Arabian hiftorians, Alexandria confifted of three cities, vi". Menna, or the port, which included Pharos, and the neighbouring parts; Alexandria, properly fa called, where the mo¬ dern Scanderia now Hands.; and Nekita, probably the Necropolis of Joftphus and Strabo. that time John, fornamed the gra?nmarian, a famous Peripatetic philofopher, being in the city, and in high favour with Amrou Ehn al Aas the Saracen general begged of him the royal library. Amrou re¬ plied, that it was not in his powmr to grant fuch a re- queft; but that he would write to the khalif on that head; fince,*without knowing his pleafure, he dared not to difpofe of a fingle book. He accordingly wrote to Omar, who was then khalif, acquainting him with the requeft of his friend : To which the ignorant ty¬ rant replied, That if thofe .books contained the fame doctrine with the koran, they could be of no ufe, fince the koran contained all neceffary truths ; but if they contained any thing contrary to that book, they ought not to be fuffered ; and therefore, whateve- their con¬ tents were, he ordered them to be deftroyed. Purfuant to this order, they were diftributed among the public baths ; where, for the fpace of fix months, they ferved to fupply the fires of thofe places, of which there was I an incredible number in Alexandria. After the city was taken, Amrou thought proper to purfue the Greeks who had fled farther up the coun- try ; and therefore marched out of Alexandria, leaving but a very flender garrifon in the place. The Greeks, who had before fled on board their (hips, being appri- fed of this, returned on a-fudden, furprifed the town, and put all the Arabs they found therein to the fword : hut Amrou, receiving advice of what had happened, fuddenly returned, and dri ve them out of it with great {laughter; after which the Greeks were io intimidated, 4. ALE that he had nothing farther to fear from them.—A few Alexandria^ years after, however, Amrou being deprived of his -v—-11 government by the khalif Othman, the Egyptians were fo much difpleafed with his difmiffion that they inclined' to a revolt; and Conftantine the Greek emperor, having1 received intelligence of their difaffeftion, began to me-' ditate the redinftion of Alexandria. For this purpofe,. he fent one Manuel, an eunuch,, and his general, with a powerful army, to retake that place ; which, by the affiftance of the Greeks in the city, who kept a fecret correfpondence with the imperial forces while at fea, and joined them as foon as they had made a defcent,. he elibeled, without any confiderable effufion of Chri- ftian blood. The khalif, now perceiving his miftake, immediately reftored Amrou to his former dignity. This ftep was very agreeable to the natives ; who ha¬ ving had experience of the military Ik ill and bravery of this renowned general, and apprehending that they ffiould be called to an account by the Greeks for their former perfidious conduft, had petitioned Othman to fend him again into Egypt.—Upon Amrou’s arrival, therefore, at Alexandria, the Copts or natives, with the traitor Al-Mokawkas (who had formerly betrayed to Amrou the fortrefs of Mefr) at their head, not only joined him, but fupplied him with all kinds of provi- ilons, exciting him to attack the Greeks without de¬ lay. This he did ; and, after a moft obftinate difpute which lafted feveral days, drove them into the town, where, for fome time, they defended themfelves with great bravery,, and repelled the utmoft: efforts of the befiegers. This fo exafperated Amrou, that he fwore, “ If God enabled him to conquer tire Greeks, he would throw down the walls of the city,, and make it as eafy of accefa as a ba-ivdy-houfe, which' lies open to every body.” Nor did he fail to execute this menace ; for- having taken the town by ftorm, he quite difmantled it, entirely demolifiring the walls and fortifications. TI12 lives of the citizens, however, wrere fpared, at leaft as far as lay in the general’s power; but many of them were put to the fword by the foldiers on their firft en¬ trance. In one quarter particularly, Amrou found them butchering,the Alexandrians with unrelenting barbarity ; to which, however, by his feafonable inter- pofition, he put a* ftop, and^on that fpot erefted a mofque, which he called the mofque of- mercy * From this time Alexandria never recovered its for¬ mer fplendor. It continued under the dominion of the khalifs till the year 9-24, when it was taken by the Ma- grebians-, two years after its great church had been de¬ ftroyed by fire. This church was called by the Arabs Al Kaifdria, or Crefarea ; and had formerly been a pa¬ gan temple, ere&ed in . honour of Saturn by the fa¬ mous queen Cleopatra,. The city was foon after abandoned by the Magre- biansi;. but in 928 they again made themfelves mailers of it: their fleet being afterwards defeated by that be¬ longing to the khalif; Abul Kafem the Magrebian ge¬ neral retired from Alexandria, leaving there only a gar* rifon of-300'men of which Thmaul, the khalif’s ad¬ miral, being apprifed, he in a few days appeared before the town, and carried off the remainder of the inhabi¬ tants to an ifland in the Nile called Abukair. This was done, to prevent Abul Kafem from meeting with any entertainment at Alexandria, in cafe he fhould think proper to. return. According to Eutychius, above 300,000 f 39i 1 A T. r. [ 39 a. 200,000 of the miferable inhabitants perifhed this year. What contributed to raife Alexandria to fuch a pro¬ digious height of fplendor as it enjoyed for a long time, was its being the centre of commerce between the eaft- ern and weftern parts of the world. It was with the view of becoming mailer of this lucrative trade, that Alexander built this city, after having extirpated the Tyrians, who formerly engrofled all the Eall-India traffic. Of the immenfe riches which that trade afford¬ ed, we may form an idea, from confidering that the Romans accounted it a point of policy to opprefs the Egyptians, efpecially the Alexandrians ; and after the defeat of Zenobia, there was a lingle merchant of Alex¬ andria who undertook to raife and pay an army out of the profits of his trade. The Greek emperors drew prodigious tributes from Egypt, and yet the khalifs found their fubjedls in fo good circumltances as to fcrew up their revenues to three hundred millions of crowns. Though the revolutions which happened in the go¬ vernment of Egypt, after it fell into the hands of the Mahometans, frequently affedled this city to a very great degree ; yet Hill the excellence of its port, and the in¬ numerable conveniences refulting from the Eaft-India trade, to whomfoever were mailers of Egypt, preferved Alexandria from total deltrudlion, even when in the hands of the moll barbarous nations. Thus, in the 13th century, when the barbarifm introduced by the Goths, See. began to wear off from the European na¬ tions, and they acquired a tafte for the elegancies of life, the old mart of Alexandria began to revive ; and the port, though far from recovering its former mag¬ nificence, grew once more famous by becoming the centre of commerce: but having fallen under the do¬ minion of the Turks, and the paffage round the Cape of Good Hope being difeovered by the Portuguefe in 1499, a fatal blow was given to the Alexandrian com¬ merce, ahd the city has fince fallen into decay. At prefent, the city of Alexandria is reckoned to have about 14,000 or 15,000 inhabitants; a ftrange coi- luvies of different nations, as well as from various parts of the Turkilh empire. They are in general given to thieving and cheating; and (like their predeceffors) feditious -above all others, were they not kept in awe by the feverity of their governmenf. The Britilh and French carry bn a confiderable commerce with them, and have each a conful refiding here.. Some Venetian lliips alfo Tail thither yearly, but with French colours, and under the prote&ion of France. The fubjedts of thofe kingdoms which keep no conful here, are iubjedf- ed to a tax by the. Grand Signior: but the Jews have found out a method of indemnifying themfelves for this difadvantage ; namely, by felling their commodities cheaper than other foreigners can afford. They are al¬ fo, favoured by the farmers of the revenue ; who know, that if they do not pay fome prfvate regard to them, the Jews have it in their power to caufe fewer merchan-- dizes come into their port during the two. years that their farm lafts. The prefent city is a kind of peninfula fituated be¬ tween the two ports. That to the weftward was called by the ancients the Pert us Eunojius, now the Old Port, and is by far the bell; Turkiih veffels only are allowed to anchor there: the other, called the New Port, is for the Chriltians; at the extremity of one of the arms of- which Hood the famous Pharos. The New Port. ■ N0io. x 2 ] ALE the only harbour for the Europeans, is clogged up with Alexandra. fand, infomuch that in llormy weather Ihips are liable to bilge ; and the bottom being alfo rocky, the cables foon chafe and part; fo that one veffel driving againll a fecond, and that againit a third, they ■are perhaps all loft. Of this there was a fatal inftance 16 or 18 years ago, when 42 veffels were dallied to pieces on the mole in a gale of wind from thetnorth-weft, and numbers have been fince loft there at different times. If it be a Iked in Europe, Why do they not repair the New Port ? the anfwer is, That in Turkey they deftroy every thing, and repair nothing. The old harbour will be deftr.oy- ed likewife, as the ballaft of veffels has been continu¬ ally thrown into it. for the laft 200 years. The fpirit of the Turkiih government is to ruin the labours of pall ages, and deftroy the hopes of future times, be- caufe the barbarity of ignorant defpotifm never confi- ders to-morrow. ' In time of war, Alexandria is of no importance; no fortification is to be feen ; even the Farillon, with its lofty towers, cannot be defended. It has not four cannon fit for fervice, nor a gunner who knows how to point them. The 500 jailifaries, who Ihould form the garrifon, reduced to half that number, kno\v no¬ thing but how to fmoke a pipe. But Alexandria is a place of which the conquelt would be of no value. A foreign power could not maintain itfelf there, as the country is without water. This mull be brought from the Nile by the kalidj, or canal of 12 leagues, which conveys it thither every year at the time of the inun¬ dation. It fills the vaults or refervoirs dug under the ancient city, and this provifion mull ferve till the next year. It is evident, therefore, that were a foreign power to take poffeffion, the canal would be Ihut, and all fupplies of waiter cut off. It is this canal alone which connedls Alexandria with Egypt; for from its fituation without the Delta, and the nature of the foil, it really belongs to the deferts of Africa. Its environs are fandy, flat, and fterile, without trees and without houfes; where we meet with- nothing but the plant which yields the kali, and a row of palm trees which follows the courfe of the kalidj or canal. The city is governed like others in the fame king¬ dom. (See Egypt.) It hath a fmall garrifon of fol- diers, part of which are Janifaries and Affaffs; who are very haughty and infolent, not only to ftrangers, but to the mercantile and induftrious part of the people, tho’ ever fo confiderable and ufeful. The government is fo remifs in favour of thefe wretches, that Mr Norden in¬ forms us, one of them did not hefitate to kill a farmer of the cuftoms, for refufing to take lefs of him than the duty impofed, and w-ent off unpuniffied ; it being a common falvo among them, that what is done can¬ not be undone. The prefent condition of Alexandria is very defpi- cable, being now' fo far ruined, that the rubbhh in many places overtops the houfes. The famous tower of Pha¬ ros has long fince been demolifhed, and a caftle, called Farillon, built in its place. The caufeway which joined the ifland to the continent is broken down, and its place fupplied by a ilone-bridge of feveral arches. Some parts of the old walls of the city are yet Hand¬ ing, and prefent us with a mafterpiece of ancient ma- fonry. They are flanked, with large towers, about 200 paces diftant from each other, wfith fmall ones in the middle. ALE [ 393 ] ALE t if Alexandria, middle. Below are magnificent e&femates, wliich may "" ‘ ferve for galleries to walk in. In the lower part of the towers is a large fquare hall, whole roof is fupported by thick columns of Thebaic flone. Above this are feveVal rooms, over which there are platforms more than 20 paces fquare. The ancient refervoirs, vaulted with fo much art, which extend underthe whole town, are almoft entire at the end of 2000 years. Of Caefar’s palace there remain only a few porphyry pillars, and the front, which is almoft: entire, and looks very beautiful. The palace of Cleopatra was built upon the walls facing the port, having a gallery on the outfide, fupported by feveral fine columns. Not far from this palace are two obelifks vulgarly called Cleo¬ patra's Needles. They are of Thebaic ftone, and co¬ vered with hieroglyphics. One is overturned, broken, and lying under the fand ; the- other is on its pedeftal. Thefe two obeli Acs, each of them of a Angle ftone, are about 60 feet high, by feven foot fquare at the bafe. Towards the gate of Rofetta, are five columns of marble on the place formerly occupied by the porticoes of the Gymnafium. The reft of the colonnade, tire defign of which was difcoverable too years ago by Maillet, has fince been deftroyed by the barbarifm of the Turks. But what moft engages the attention of travellers is the Pillar of Pompey, as it is commonly called, fitua- ted at a quarter of a league frofh the fouthern gate. It is compofed of red granite. The capital is Corin¬ thian, with palm leaves, and not indented. It is nine feet high. The flraft and the upper member of the bafe are of one piece of go feet long, and 9 in diame¬ ter. The bafe is a fquare of about 15 feet on each fide. This block of marble, 60 feet in circumference, refts on two layers of ftone bound together with lead ; which, however,- has not prevented the Arabs from forcing out feveral of them, to- fearch for an imaginary treafure. The whole column is 114 feet high. It is perfectly well poliflied, and only a little fhivered on the eaftern fide. Nothing can equal the majefty of this monument; feen from a diftance, it overtops the town, and ferves as a fignal for veflels. Approaching it nearer, it produces an aftonifhment mixed with awe. One can never be tired with admiring the beauty of the capital, the length of the ftiaft, nor the extraordi¬ nary Simplicity of the pedeftal. This laft has been fomewhat damaged by the inftruments of travellers, who are curious to poffefs a relick of this antiquity; and one of the volutes of the column was immaturely brought down about twelve years ago, by a prank of fome Engliflr captains, which is thus related by Mr Irwin. Thefe jolly fons of Neptune had been pufhing about the can on board one of the fhips in the harbour, until a ftrange freak entered into one of their brains. The eccentricity of the thought occafioned it immediately ,|i to be adopted ; and its apparent impoflibility was but IFoyagt and a fpur for the putting it into execution. The boat monte, was'ordered ; and with proper implements for the at- 1 IP- 37°- tempt, thefe enterprifing heroes pufhed aftiore, to drink a bowel of punch on the top of Pompey’s pillar .! At the fpot they arrived; and many contrivances were propofed to accomplifii the defired point. But their labour was vain ; and they began to defpair of fuccefs,- when the genius who ftruck out the frolic happily fug- Vol. L Part I. gefted the means of performing it. A man was dif- Alexandria, patched to the city for a paper kite. The inhabitants -—V—"* were by this time apprized of what was going forward, and flocked in crowds to be witnefles.of the addrefs and boldnefs of the Englifh. The governor of Alex¬ andria was told that thefe feamen were about to pull down Pompey’s pillar. But whether he gave, them credit for their refpeft to the Roman warrior, or to the Turkifh government, he left them to themfelves ; and politely anfwered, that the Englifli were too great patriots to injure the remains of Pompey. He knew little, however, of the difpofition of the people who were engaged in this undertaking. Had the Turkifh empire rofe in oppoiition, it would not perhaps at that moment have deterred them. The kite was brought, and flown fo directly over the pillar, that when it fell on the other fide, the firing lodged upon the capital. The chief obftacle was now overcome. A two-inch rope was tied to one end of the firing, and drawn over the pillar by the .end to which the kite was affixed. By this rope one of the feamen afcended to the top ■; and in lefs than an hour, a kind of fhroud wa£ con- ftructed, by which the whole company went up, and drank their punch amid the fhouts of the aftonifhed multitude. To the eye below, the capital of the pil¬ lar does not appear capable of holding more than one man upon it; but our feamen found it -could contain no lefs than eight perfons very conveniently. It is aftonifhing that no accident befel thefe madcaps, in a fituation fo elevated, that would have turned a land- man giddy in his fober fenfes. The only detriment which the pillar received, was the Jofs of the volute be- forementioned ; which came down with -a thundering found, and was carried to England by one of the cap¬ tains, as a prefent to a lady who commiflioned him for a piece of the pillar. The difcovery which they made amply compenfated for this mifchief; as without their evidence, the world would, not have known at this . hour, that there was originally a ftatue on this pillar, one foot and ancle of which are ftill remaining. The ftatue muft have been of a gigantic fize, to have ap¬ peared of a man’s proportion at fo great an height. There are circumftances in this ftory which might give it an air of fi£Uon, were it not demonftrated be¬ yond all doubt. Befides the tellimonies of many eye- witneffes, the adventurers themfelves have left us a to¬ ken of the fadt, by the initials of their names, which are very legible in black' paint juft beneath the capital. Learned men and travellers have made many fruit- lefs attempts to. difcover in honour of what prince it was ere&ed. The heft informed have concluded, that it could hot be in honour of Pompey, fince neither Strabo nor Diodorus Siculus have fpoken of it. The Arabian Abulfeda, in his defcription of Egypt, .calls it the Pillar of Severws. And hiftory informs usf, that f Vide Spay this emperor “ vifited the city of Alexandria: That tian's L fe he granted a fenate to its inhabitants, who until that "'f' '”’”er*s* time, under the fubjedtion of a Angle Roman magi- 7’ ftrate, had lived without any national council, as under the reign of the Ptolemies, when the will of the prince was their only law : That he did not confine his be- nefattions there ; he changed feveral laws in their fa¬ vour.” This column, therefore, Mr S a vary concludes to have been eredled by the inhabitants as a mark of their gratitude to Severus. And in a Greek infcrip- 3 D tion. ALE Alexandria, tion, now half effaced, but vifible on the weft fide when the fun fhines upon it, and which probably was legible in the time of Abulfeda, he fuppofes the name of Severus to have been preferved. He further ob- ferves, that this was not the only monument erefted to [ 394 1 ALE water of the fea, as pure and trarifparent as cryftal. Seated on the ftone bench, the water rifes a little above the waift; while the feet foftly repofe on a fine fand. The waves of the fea are heard roaring againft the rock, and foaming in the canal.

On the fouth-weft fide of the city, at a mile’s di- ftance, are fituated the catacombs, the ancient burial- place of Alexandria; and although they cannot be compared to thofe of the ancient Memphis, which the Arabs will not permit to be vifited, in order to make the better market of their mummies, it is probable that, the method of embalming being the fame, the form of thefe catacombs can only differ in their pro¬ portions.—The Baron de Tott, in deferibing thefe, obferves, “ that Nature not having furnifhed this part of Egypt with a ridge of rocks, like that which runs parrallel with the Nile above Delta, the ancient inhabi¬ tants of Alexandria could only have an imitation by dig¬ ging into a bed of folid rock ; and thus they formed Necropolis, or ‘ City of the Dead.’ The excavation is from 30 to 40 feet wide, and 200 long and 25 deep, and is terminated by gentle declivities at each end. The two fides, cut perpendicularly, contain feveral openings, about 10 or 12 feet in width and height, hollowed horizontally ; and which form, by their dif¬ ferent branches, fubterranean ftreets. One of thefe, which curiofity has difencumbered from the ruins and fands that render the entrance of others difficult or im- poffible, contains no mummies, but only the places they occupied. The order in which they were ranged coolnefs which is truly delicious under a burning iky. This place is vulgarly called the Bath of Cleopa¬ tra.

But ■this high antiquity, and the authority of the tradition to which the patriarch refers, have been difputed; nor are the moft accurate biblical writers agreed about its age.

Lat. 53. 30. 3 D 2 ALFRED, A L F [ 396 ] A L F AIfred- i ALFRED, or ^Elfred, the Great, king of Eng- lancl, was the fifth and youngeft fon of ^Ethelwolf king of the Weft Saxons, and was born at Wantage in Berklhire in 849. He diftinguifhed himfelf, du¬ ring the reign of his brother Ethelred, in feveral en¬ gagements againft the Danes; and upon his death fuc- ceeded to the crown, in the yean871, and the 22d of his age. At his afcending the throne he found him¬ felf involved in a dangerous war with the Danes, and placed in fuch circumftances of diftrefs as called for the greateft valour, refolution, and all the other vir¬ tues 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 againft thofe formidable ene¬ mies. After many battles gained on both fides, he was at length reduced to the greateft diftrefs, and was entirely abandoned by his fubje&s. In this fituation, Alfred, conceiving himfelf no longer a king, laid afide all marks of royalty, and took Ihelter in the houfe of one who kept his. cattle. He retired afterwards to the ifle of aEthelingey in Somerfetfhire, where he built a fort for the fecurity of himfelf, his family, and the few faithful fervants who repaired thither to him. When he had been about a year in this retreat, having been inform¬ ed that fome of his fubjefts had routed a great army of the Danes, killed their chiefs, and taken their magical ftandard (a), he iffued his letters, giving notice where he was, and inviting his nobility to come and confult 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 fufpicion, he was every where admitted, and had the honour to play be¬ fore their princes. Having thereby acquired, an exadt knowledge of their fituation, he returned in great fe- crecy to his nobility, whom he ordered to their refpec- 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 randezvous at the great wood, called Sefavood, in Wiltfhire. This affair was tranfac- ted fo fecretly and expeditioufly, that, in a little time, the king, at the head of an army, approached the Danes, before they hfd the leaft intelligence of his de- fign. Alfred, taking advantage of the furprife and terror they were in, fell upon them, and totally defeat¬ ed them at iEthencJune, now Eddington. Thofe who efcaped fled to a neighbouring caftle, where they were foon befieged, and obliged to furrender at difcretion. Alfred granted them better terms than they could ex- pedt. He agreed to give up the whole kingdom of the Eaft-Angles to fuch as would embrace the Chriftian re¬ ligion, on condition they fhould oblige the reft of their -.countrymen to quit the ifland, and, as much as it was in their power, prevent the landing of any more fo¬ reigners. For the performance thereof he took hofta- ges; and when, in purfuance of the treaty, Guthrum the Danifh captain came, with thirty of his chief offi¬ cers, to be baptized, Alfred anfwered for him at the font, and gave him the name of Mthelfiane; and cer¬ tain laws were drawn up betwixt the king and Gu¬ thrum for the regulation and government of the Danes fettled in England. In 884, a frefh number of Danes landed in Kent, and laid fiege to Rochefter ; but the king coming to the relief of that city, they were ob¬ liged to abandon their defign. Alfred had now great fuccefs; which was chiefly owing to his fleet, an ad¬ vantage of his own creating. Having fecured the fea- coafts, he fortified the reft of the kingdom with caftles and walled towns; and he befieged and recovered from the Danes the city of London, which he refolved to re¬ pair, and keep as a frontier (b). After fome years refpite, Alfred was again called into the field : for a body of Danes, being ' worfted in the weft of France, came with a fleet of 250 fail on the coaft of Kent; and having landed, fixed themfelves at Apple-tree: Ihortly after, another fleet of 80 veffels coming up the Thames, the men landed, and built a fort at Middleton. Before Alfred marched againft the enemy, he obliged the Danes, fettled in Northumber¬ land and Effex, to give him hoftages for their good behaviour. He then moved towards the invaders, and pitched his camp between their armies, to prevent their junftion. A great body, however, moved off to Ef¬ fex; and croffing the river, came to Farnham in Surry, where they were defeated by the king’s forces. Mean while the Danes fettled in Northumberland, in breach of treaty, and notwithftanding the hoftages given, e- quipped two fleets; and, after plundering the northern and fouthern coafts, failed to Exeter, and befieged it. The king, as foon as he received intelligence, marched againft them ; but before he reached Exeter, they had got poffeffion of it. He kept them, however, blocked up on all fides; and reduced them at laft to fuch extremi¬ ties, that they were obliged to eat their horfes, and were even ready to devour each other. Being at length ren¬ dered defperate, they made a general fally on the be- fiegers; (a) “ This (fays Sir John Spelman) was a banner with the image of a raven magically wrought by the three fillers of Hinguar and Hubba, on purpofe for their expedition, in revenge of their father Lodebroch’s murder,, made, they fay, almoft in an inftant, being by them at once begun and finiflied in a noontide, and believed by the Danes to. have carried great fatality with it, for which it was higlily efteemed by them. It is pretended, that being carried in battle, towards good fuccefs it would always feem to clap its wings, and make as if it would; fly ; but towards the approach of milhap, it would hang down and not move.” Life of Alfred, p. 6r. (b) The Danes had poffeffed themfelves 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 themfelves in ; neither was it taken from them but by a clofe fiege. However, when it came into the king’s hands, it was in a miferable condition, fcarce habitable, and all1 its fortifications ruined. The king, moved by the importance of the place, and the defire of ftrengthening his- frontier againft the Danes, reftored it to its ancient fplendor. And obferving, that, through the confufion o£ the times, many, both Saxons and Danes, lived in a loofe diforderly manner, without owning any government^ he offered thenrnow a comfortable eftablifhment, if they would fubmit and become his fubjedts. This propofi- tion was better received than he expefted ; for multitudes growing weary of a vagabond kind of life, joyfully accepted fuch an offer. Chr.m. Sax. p. 88. A L F [ 397 7 A L F Alfred, fiegers ; but were defeated, though with great lofs on the king’s fide. The remainder of this body of Danes fled into Eflex, to the fort they had built there, and to their fhips. Before Alfred had time to recruit him- felf, another Danilh leader, whofe name was Laf, came with a great army out of Northumberland, and de- ftroyed all before him, marching on to the city of Werheal in the* weft,- which is fuppofed to be Chefter, where they remained the reft of that year. The year following they invaded North-Wales; and after having plundered and deftroyed every thing, they divided, one body returning to Northumberland, another into the territories of the Eaft-Angles ; from whence they pro¬ ceeded to Eflex, and took pofieflion of a fmall ifland called Me rejig. Here they did not long remain : for- having parted, fome failed up the river Thames, and others up the Lea-road; where drawing up their fhips, 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 repulfed with great lofs: at har- veft-time the king himfelf was obliged to encamp with a body of troops in the neighbourhood of the city, in order to cover the reapers from the excurfions of the Danes. As he was one day riding by the fide of the river Lea, after fome obfervation, he began to think that the Danifh fhips might be laid quite dry: this - he attempted, and fucceeded; fo that the Danes de- ferted their fort and fhips, and marched away to the banks of the Severn, where they built a fort, and win- - tered at a pla?e called Quatbrig (c). Such of the Da¬ nifh fhips as could be got off, the'' Londoners carried into their own road; the reft they burnt and deftroyed. Alfred enjoyed a profound peace during the three laft years of his reign, which he chiefly employed in eftablifhing and regulating his government, for the fecu- rity of himfelf and his fucceffors, as well as the eafe and benefit of his fubjetts in general. After a troublefome reign of 28 years, he died on the i^th of October A. D. 900; and was buried at Winchefter, in Hyde- , abbey, under a monument of porphyry. All our hiftorians agree in diftinguiftiing him as one of the moil valiant, wifeft, and belt of kings that ever reigned in England ; and it is alfo generally allowed, that he not only digefted feveral particular laws ftill in being, but that he laid the firft foundation of our pre- fent happy conftitutiou. There is great reafon to be¬ lieve that we are indebted to this prince for trials by juries ; and the doomfday book, which is preferved in the exchequer, is thought to be no more than ano¬ ther edition of Alfred’s book of Winchefter, which contained a furvey of the kingdom. It is faid alfo, that he was the firft who divided the kingdom into fhjres: what is aferibed to him is not a bare divifion of the country, but the fettling a new form of judicature; for after having divided his dominions into fhires, he fub- divided each fhire inta three parts, called trythings. There are fome remains of this ancient divifion in the ridings of Yorkfhire,. the laths of Kent, and the three parts of Lincolnfhire. Each trything was divided into Alfred, hundreds or wapentakes ; and thefe again into tythings or dwellings of ten houfeholders: each of thefe houfe- holders flood engaged to the king, as a pledge for the good behaviour of his family, and all the ten were mu¬ tually pledges for each other; fo that if any one of the tything was fufpefted of an offence, if the head bo¬ roughs or chiefs of the tything would not be fecurity for him, he was imprifoned ; and if he made his efcape, the tything and hundred were fined to the king. .Each* ftiire was under the government of an earl, under whom was the reive, his deputy; fince, from his office, cal¬ led Jhire-reive, or Jheriff. And fo effectual were thefe regulations, that it is faid he caufed bracelets of gold to be hung up in the highways, as a challenge to rob¬ bers, and they remained untouched. In private life, Alfred was the moft amiable man in his dominions; of fo equal a temper, that he never fuffered either fadnefs or unbecoming gaiety to enter his mind ; but appeared always of a calm, yet cheerful difpofition, familiar to his friends, juft even to his ene¬ mies, kind and tender.to all. He was a remarkable ceconomift of his time, and Afferius has given us an account of the method he took for dividing and keep¬ ing an account of it: he caufed fix wax-candles to be made, each of 12 inches long, and of as many ounces weight; on the candles the inches were regularly mark¬ ed, and having found that one of them burnt juft 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 wafted by the impreffion of the air on the flame, to remedy this inconvenience, he invented lan- thorns, there being then no glafs in. his dominions. This prince, we are told, was 12, years of age be¬ fore a matter could be procured in the weftern kingdom, to teach, him the alphabet; fueh was the ftate of learn¬ ing when Alfred began to reign. He had felt the mi- fery of ignorance; and determined even to rival his co- temporary Charlemagne in the encouragement of lite¬ rature. He is fuppofed to have appointed perfons to read ledtures at Oxford, and is thence confidered as the founder of that univerfity. By other proper eftablifti- ments, and by a general encouragement to rtiemof abi¬ lities, he did every thing in his power to diffufe know¬ ledge throughout his dominions. Nor was this end promoted more by his countenance and encouragement" than by his own example and his writings. For not- withftanding the latenefs of his initiation, he had ac¬ quired extraordinary erudition ; artd, had he not been, illuftrious as-a king, he would have been famous as an - author. His works are, I. Breviarutn quoddam collec- tum ex Legibus Trojanorum, &c. lib. I. A Breviary col- ledted out of the Laws of the Trojans, Greeks, Britons, Saxons, and Danes, ih one Book.

Hertford and Bow; for at Hertford was the Danilh £brt,: and from thence they made frequent excurfions on the inhabitants of London-.. Authors are not agreed as to the method the king purfued in laying dry the Danifh fliips: Dugdale fuppofea that he did it by ftraitening the channel; but Henry of Huntingdon alleges, that he cut feveral canals, which exhaufted its water.

Here he com- pofed his “ Newtonian Philofophy for the Ladiesas Fontenelle had done his Cartelian Aftronomy, in the work intitled, “ The Plurality of worlds.” He was noticed by the king of Pruffia, who gave him marks of the efteem he had for him. He died at Pifa the 23d of May, 1764; and ordered his own maufoleum, with this infcription to be fixed upon it: “ Hie jacet Alga- “ rottus, fed non omnis.” He is allowed to have been a very great connoifleur in painting, fculpture, and ar¬ chitecture. He contributed much to the reformation of the Italian opera.

ALGEBRA, Definition A General method of computation, wherein figns and etymo- and fymbols, commonly the letters of the alpha- iugy‘ bet, are made ufe of to reprefent numbers, or any other quantities. This fcience, properly fpeaking, is no other than a kind of fhort-hand, or ready way of writing down a chain of mathematical reafoning on any fubjeCt what¬ ever ; fo that it is applicable to arithmetic, geometry, aftronomy, menfuration of all kinds of folids, &c. and the great advantages derived from it appear manifeftly to arife from the concifenefs and perfpicuity with which every propofition on mathematical fubjeCts can be writ¬ ten down in algebraic characters, greatly fuperior to the tedious circumlocutions which would be neceflary were the reafoning to be written in words at length. With regard to the etymology of the word algelra, it is much contefted by the critics. Menage derives it' from the Arabic algiaharat, which fignifies the reftitution of any thing broken ; fuppofing that the principal part of algebra is the confideration of broken numbers. Others rather borrow it from the Spanilh, algebri/la, » perfon who replaces diflocated bones; ad- History. ALGEBRA. 399 ding, that algebra has nothing to do with fraction. Some, with M. d’Herbelot, are of opinion, that alge¬ bra takes its name from Gebar, a celebrated philofo- pher, chemift, and mathematician, whom the Arabs call Giaber, and who is fuppofed to have been the in¬ ventor. Others from gefr, a kind of parchment made of the Ikin of a camel, whereon Ali and Giafer Sadek wrote, in myftic chara&crs, the fate of Mahomctanifm, ami the grand events that were to happen till the end of the world. But others, with more probability, de¬ rive it from geber ; a word whence, by prefixing the ar¬ ticle al, we have formed algebra ; which is pure Ara¬ bic, and properly fignifies the reduction of fractions to a whole number. However, the Arabs, it is to be ob- ferved, never ufe the word algebra alone, to exprefs what we mean by it; but always add to it the word macabelah, which fignifies oppofition and comparifon : thus algebra-almacabelab, is what we properly call al- ■ gebra. ► Some authors define algebra, The art of folving ma¬ thematical problems; but this is rather the idea of ana- lyfis, or the analytic art. The Arabs call it, The art of rejlitution and comparifon ; or, The art of reflation and equation. Lucas de Burgo, the firft European who wrote of algebra, calls it, Regula rei et cenfus ; that is, the rule of the root and its fquare; the root with them being called res, and the fquare cenfus. Ci¬ thers call it Specious Arithmetic ; and fome, Univerfal Arithmetic. It is highly probable that the Indians or Arabians firft invented this noble art: for it may be reafonably fuppofed/ that the ancient Greeks wrere ignorant of It; becaufe Pappus, in his mathematical colle&ions, where he enumerates their analyfis, makes no mention of any thing like it; and, befides, fpeaks of a local problem, begun by Euclid, and continued by Apol¬ lonius, which none of them could fully refolve ; which doubtlefs they might eafily have done, had they known any thing of algebra. Diaphantus was the firft Greek writer of algebra ; who publifhed 13 books about the year 800, though only fix of them were tranflated into Latin, by XyJan- der, in 1575 ; and afterwards, viz. anno 1621,. in Greek and Latin, by M. Bachet and Fermat, with ad¬ ditions of their own. This algebra of Diaphantus’s only extends to the folution of arithmetical indeter¬ minate problems. Before this tranflation of Diaphantus came out, Lu¬ cas Pacciolus, or Lucas de Burgo, a Minorite friar, publifhed at Venice, in the year 1494, an Italian trea- tife of algebra. This author makes mention of Leo- nardus Pifanus, and fome others, of whom he had learn¬ ed the art ; but we have none of their writings. He adds, that algebra came originally from the Arabs, and never mentions Diaphantus ; which makes it probable, that that author was not then known in Europe. His algebra goes no farther than fimple and quadratic equa¬ tions. After Pacciolus appeared Stifelius, a good author ; but neither did he advance any farther. After him came Scipio Ferreus, Cardan, Tarta- gilla, and fome others, who reached as far as the fo¬ lution of fome cubic equations. Bombelli followed thefe, and went a little farther. At laft came Nun- nius, Ramus, Schoner, Salignac, Clavius, &c. who all H'ftory. of them took different courfes, but none of them went beyond quadratics. In 1590, Vieta introduced what he called his Specious Arithmetic, which confifts in denoting the quantities, both known and unknown, by fymbols or letters. He alfo introduced an ingenious method of extracting the roots of equations, by approximations; fince greatly improved and facilitated by Raphfon, Halley, Maclau- rin, Simpfon, and others. Vieta was followed by Oughtred, who, in his Clavis Mathematica, printed in 1631, improved Vieta’s me¬ thod, and invented feveral compendious characters, to fhowthe fums, differences, reCtangles,fquares, cubes, &c. Harriot, another Englifhman, cotemporary with Oughtred, left feveral treatifes at his death ; and among the reft, an Analyfis, or Algebra, which was printed in 1631, where Vieta’s method is brought into a ftill more commodious form, and is much efteemed to this day. In 1657, Des Cartes publifhed his geometry, where¬ in he made ufe of the literal calculus and the algebraic rules of Harriot; and as Oughtred in his Clavis, and Marin. Ghetaldus in his books of mathematical com- pofition and refolution publifhed in 1630, applied Vieta’s arithmetic to elementary geometry, and gave the conftruftion of fimple and quadratic equations; fo Des Cartes applied Harriot’s method to the higher geometry, explaining the nature of curves by equations, and adding the conftniftions of cubic, biquadratic, and other higher equations. Des Cartes’s rule for conftru&ing cubic and biqua¬ dratic equations, was farther improved by Thomas Ba¬ ker, in his Clavis Geometrica Catkdica, publifhed in 1684 ; and the foundation of fuch conftruCtions, with the application of algebra to the quadratures of curves, queftions de maximis et minimis, the centrobaryc me¬ thod of Guldinus, &c. was given by R. Slufius, in 1668; as alfo by Fermat in his Opera Mathematica, Roberval in the Mem. de Mathem. et de Phyfque, and Barrow in his Left. Geomet. In x 708, algebra was ap¬ plied to the laws of chance and gaming, by R. de Mont- mort; and fince by de Moivre and James Bernouilli. The elements of the art were compiled and publifhed by Kerfey, in 1671 ; wherein the fpecious arithmetic, and the nature of equations, are largely explained, and illuftrated by a variety of examples : the whole fubftance of Diaphantus is here delivered, and many things add¬ ed concerning mathematical compofition and refolution from Ghetaldus. The like has been fince done by Preftet in 1694, and by Ozanam in 1703 : but thefe authors omit the application of algebra to geometry; which deleft is fupplied by Guifnec in a French treatife exprefsly on the fubjeft publifhed in 1 704, and 1’Ho- pital in his analytical treatife of the conic feftions in 1707. The rules of algebra are alfo compendioufly delivered by Sirlfaac Newton, in his Aritkmetica i'ni- verfalis, firft publifhed in 1707, which abounds in fe- left examples, and contains feveral rules and method* inventabz divided by 'imbe is the? fraftion 2mbc.

A L G fun 'amen- Rule I. The terms of the dividend are to be ranged r,Pera' according to the powers of fome one of its letters ; ^ and thofe of the divifor, according to the powers of the fame letter. Thus, if is the dividend, and a-\-b the divifor, they are ranged according to the powers of a. 2. The firfl: term of the dividend is to be divided by the firft term of the divifor (obferving the general rule for the ligns); and this quotient being fet down as a part of the quotient wanted, is to be multiplied by the whole divifor, and the produft fubtrafted from the dividend. If nothing remain, the divi- fion is finiflied : the remainder, when there is any, is a new dividend. Thus, in the preceding example, a1 divided by a, gives a, which is the firft part of the quotient want¬ ed : and the product of this part by the whole divifor a-\-b, viz. al-i-ab being fubtra&ed from the given di¬ vidend, there remains in this example ab-\-b*. 3. Divide the firft term of this new dividend by the firft term of the divifor. as before, and join the quo¬ tient to the part already found, with its proper fign : then multiply the whole divifor by this part of the quotient, and fubtraft the produft from the new dividend ; and thus the operation is to be continued till no remainder is left, or till it appear that there will always be a remainder. Thus, in the preceding example, -\-ab, the firft term of the new dividend divided by a, gives b; the product of which, multiplied by a+b, being fubtradl- ed from ab+b1, nothing remains, and a-\-b is the true quotient.

They are alfo called proportionals. Thus, if <7, b, c, d, are the four quantities, then and their ratio is thus denoted a : b : : c •. d. Cor. Three quantities may be geometrical propor¬ tionals, viz. by fdppofing the two middle terms of the four to be equal. If the quantities are a, b, c, then ah and the proportion is expreffed thus, a:b:c. 4- —&c. 1 a1 1 This quotient becomes a ferious, of which the law of continuation is obvious, without any farther opera¬ tion. In fuch cafes, when we arrive at a remainder of one term, it is commonly fet down with the divifor below it, after the other terms of the quotient, which then becomes a mixt quantity. Thus the laft quotient is alfo expreffed by a— Ta + x Prop. I. The product of the extremes of four quan¬ tities geometrically proportional is equal to the product of the means; and converfely. t Let a\b::c:d.

By the preceding operations quantities of the fame kind may be compared together. The relation ariling from this comparifon is called ratio or proportion, and is of two kinds. If we confi- der the difference of the two quantities, it is called arithmetical proportion ; and if we confider their quo¬ tient, it is called geometrical proportion. This laft be¬ ing moft generally ufeful, is commonly called fimply proportion. j. Of Arithmetical Proportion. Definition. When of four quantities the difference of the firft and fecond is equal to the difference of the third and fourth, the quantities are called arithmetical proportionals. Cor. Three quantities maybe arithmetically propor¬ tional, by fuppofing the two middle terms of the four to be equal. Prop. In four quantities arithmetically proportional, the fum of the extremes is equal to the fum of .the means. Let the four be a, b, c, d. Therefore from Def, tz—bzzc—d; to thefe add b-\~d and a-\-d—b-\-c. Cor. 1. The product of the extremes of three quan¬ tities, geometrically proportional, is equal to the fquare of the middle term. Cor. 2. Of four quantities geometrically proportion¬ al, any three being given, the fourth may be found. Ex. Let a, b, c, be the three firft; to find the 4th. Let it be x, then a:b::c:x, and by this propofition, ax—be be. and dividing both by a, x~ —. This coincides with the Rule of Three in arithmetic, and may be confidered as a demonftration of it. In applying the rule to any particular cafe, it is only to be obferved, that the quantities muft be fo connedted and fo arranged, that they be proportional, according to the preceding definition. Cor, 3. Of three geometrical proportionals, any two being given, the third may be found. Prop. II. If four quantities be geometrically pro¬ portional, then if any equimultiples whatever be taken of the firft and third, and alfo any equimultiples what¬ ever of the fecond and fourth; if the multiple of the firft be greater than that of the fecond, the multiple of the third will be greater than that of the fourth; and if equal, equal ; and if lefs, lefs. For, let a} b, c, d, be the four proportionals. Of the Part I. A L G Of Equa- the fir(l and third, ma and me may reprefent any equl- tlons' multiples whatever, and alfo nb, nd, may reprefent v any equimultiples of the fecohd and fourth. Since a:bt:c:d, ad—bc; and hence multiplying by mn, mnad~mnbc't and therefore (Conv. Prop, i.) ma: nb : : me: nd; and from 'the definition of pro¬ portionals, it is plain, that if ma is greater than nb, me muft be greater than nd; and if equal, equal; and iflefs, lefs. Prop. III. If four quantities are proportionals, they will alfo be proportionals when taken alternately or in- verfely, or by compofition, or by divilion, or by con- verfion. See Def. 13. 14. 15. 16. 17. of Book V. of Euclid, Simfon’s edition. By Prop. II. they will alfo be proportionals accord- ino to Def. 5. BookV. of Euclid; and therefore this propofition is demonftrated by propofitions 16, B, 18, 17, E, of the fame book. Qthenvife algebraically. Let a '.b'.'.cvd, and therefore ad—bc.

(Prop. 1.) Prep. IV. If four numbers be proportionals, accord¬ ing to Def. 5. V. B. of Euclid, they will be geome¬ trically proportional, according to the preceding defi¬ nition. \Ji, Let the four numbers be integers, and let them be a, b, c, d. Then if b times a and b times c be ta¬ ken, and alfo a times b and a times d, fince ba the. multiple of the firlt is equal to ab the multiple of the fecond, be, the multiple of the third, muft be equal to ad the multiple of the fourth. And fince be—ad, by Prop. 1. a, b, c, and d, muft be geometrical propor¬ tionals. zdly, If any of the numbers be fractional,, all the four being multiplied by the denominators of the frac¬ tions, they continue proportionals, according to Def. 5. B. V. Euclid (by Prop. 4. of that book) ; and the four integer quantities produced being fuch. propor¬ tionals, they will.be geometrical proportionals, by the firft part of this prop.; and therefore, being reduced by divifion to their original form,, they manifeftly will, remain proportionals, according to the algebraical de¬ finition. CHAP. III. Sect. I. Of Equations in general, arid cf the Solution of fimple Equations. Definitions. I* An Equation may in general be defined to be a propoiition afferting the equality of two quantities; E B R A. 407 and is exprefled by placing the fign = between Of Equa- them> , ti»n3- „ 2. When a quantity Hands alone upon one fide of an equation, the quantities on the other fide are faid to be a value of it. Thus in the equation xzzb^-y—d, x Hands alone on one fide, and b-^-y—d is a value of it. 3. When an unknown quantity is made to ft'and alone on one fide of an equation,, and there are only known quantities on the other, that equation, is faid to be refolved; and the value of the unknown quantity is called a root of the equation. 4. Equations containing only one unknown quantity and its powers, are divided into orders, according to the higheft power of the unknown quantity to be found in any of its terms. If the higheft power of 1 1 ft, 1 The E- T Simple, the unknown quanti- > 2d, >- quatfon Xfifiuadrat. ty in any term be the J 3d,&c. J iscalled (^Cubic, 8ic. But the exponents of the unknown quantity are fup* pofed - to be integers, and the equation is fuppofed to be cleared of fractions, in which the unknown quanti ty, or any of its powers, enter the denominators. Thus, x 4-^ = —^— is a fimple equation; 3.V—I2» when cleared of the fraCtion by multiplying both Tides by zx, becomes 6x2—5 = 24* a quadratic. x3—2x4 rrx6—26 is an equation of the fixth order, &c» As the general relations of quantity which may be treated of in algebra, are almoft univerfally either that of equality, or fuch as may be reduced to that of e- quality, the doCtrine of equations becomes one of the chief branches of the fcience. The moft common and ufeful application of algebra is in the inveftigation of quantities that are unknown, from certain given relations to each other, and to fuch as are known ; and hence it has been called the analy¬ tical art. The equations employed for expreffing thefe relations muft therefore contain one or more unknown quantities; and the principal bufinefs of this art will be, the deducing equations containing only one un¬ known quantity, and refolving them. The folution of the different orders of equations will be fucceflively explained. The preliminary rules in the following feClion are ufeful in all orders, and are alone fufficient for. the folution of fimple equations. $;i. Offmiple Equations, and iheir Reflation. Simple equations are refolved by the four fundamen¬ tal operations already explained ; and the application of them to this purpofe is contained'in the following rules. Rule 1. Any quantity maybe tranfpofed from one fide of an equation to the other, by changing its fign. Thus, if 3.V—10 = 2x4-5 Then, 3.V—2x= io-f-5 or x= 15 Thus alfo, qx-\-b—a-{-2x. By tranfp. ^x—a—F. This rule is obvious from prob. 1. and 2.; for it is- equivalent to adding equal quantities to both fides of the equation, or to fubtrading equal quantities from: both fides. Cor.. A. Or A L G E Cor. The figns of all the terra's of an equation may • be changed into the contrary figns, and it will continue- to be true. Ruk. 2. Any quantity by which the unknown quan¬ tity is multiplied may be taken away, by dividing all the other quantities of the equation by it.

Thus, —^bJf-c Alfo, if —7~<: x=ab-\-ac ax—b=cx And by tranf. ax—cx=b b And by div. x~ 1 a—c For if all the terms of the equation are multiplied by the fame quantity, it remains a true propofition. Corollary to the three lajl Rules. If any quantity be found on both fides of the equa¬ tion, with the fame fign, it may be taken away from both. (Rule 1.) Alfo, if all the terms in the equation are multiplied or divided by the fame quantity, it may be taken out of them all. (Rule 2. and 3.) Ex. If then 3x=b.

LaJUy, If the unknown quantity is multiplied by any known quantity, it may be made to Hand alone by R. 2. and the equation will then be refolved. Def. 3.

From the refolution of equations vve obtain the re- folution of a variety of ufeful problems, both in pure mathematics and phyfics, and alfo in the practical arts founded upon thefe fciences. In this place, we con- fider the application of it to thofr queitions where the quantities are expreffed by numbers, and their magni¬ tude alone is to be confidered. When an equation, containing only one unknown quantity, is deduced from the queltion by the follow¬ ing rules, it is fometimes called a final equation. If it be Ample, it may be refolved by the preceding rules; but if it be of a fuperior order, it mull be refolved by the rules afterwards to be explained. The examples in this chapter are fo contrived, that the Anal equation may be Ample. The rules given in this feflion for the folution of queftions, though they contain a reference to Ample equations only, are to be confidered as general, and as applicable to queftions which produce equations of any order. General Rule. The unknown quantities in the queftion propofed mull be expreffed by letters, and the rela¬ tions of the’ known and unknown quantities con¬ tained in it, or the conditions of it, as they are call¬ ed, mull be exprelfed by equations. Thefe equa¬ tions being refolved by the rules of this fcience, will give the anfwer of the queftion. For example, if the queftion is concerning two num¬ bers, they may be called x and^>, and the conditions from which they are to be invelligated mull be expref- Able by equation?. Thus, if it be required that the Aim of two numbers fought be 60, that condition is ex- prelfed thus If their difference mull be 24, then x—y=24 If their produft is 1640, then xy=i640 If their quotient muft be 6, then 6 If their ratio is as 3 to 2, then 7 2x_ Thefe are fome of the relations which are moft ea- Aly expreffed. Many others occur which are lefs ob¬ vious ; but as they cannot be deferibed in particular rules, the algebraical expreffion of them is beft explain¬ ed by examples, and muft be acquired by experience. 1 x+y=6o 5 .

The folution, however, will be obtained by fuch fubfttui¬ tions as are ufed in Ex. 7. and 9. or by fimilar opera¬ tions, which need not be particularly defciibed. Corollary to the preceding Rules. It appears that, in every queftion, there mull be as many independent equations as unknown quantities; if there are not, then the queftion is called indetermi¬ nate^ becaufe it may admit of an infinite number of anfwers; fince the equations wanting may be aflumed at pleafure. There may be other circumftances, how¬ ever, to limit the anfwers to one, or a precife number, and which, at the fame time, cannot be direftly ex- preffed by equations. Such are thefe; that the num¬ bers muft be integers, fquares, cubes, and many others. The folution of fuch problems, which are alfo called diophantine, (hall be confidered afterwards. Scholium. On many occafions, by particular contrivances, the operations by the preceding ruks may be much abrid¬ ged. This however, muft be left to the Ikill and praftice of the learner. A few examples are the following. 1. It is often eafy to employ fewer letters than there are unknown quantities, by expreffing fome of them from a fimple relation to others contained in the con¬ ditions of the queftion. Thus, the folution becomes more eafy and elegant. (See Ex. 4. 5.) 2. Sometimes it is convenient to exprefs by letters, not the unknown, quantities themfelves, but fome o- ther quantities connefted with them, as their fum,. difference, &c. from which they may be eafily derived. (See Ex. 1. of chap. 5.) In the operation alfo, circumftances will fuggeft a more eafy road than that pointed out by the general rules. Two of the original equations may be added together, or may be fubtra£led; fometimes they muft be previoufly multiplied by fome quantity, to render fuch addition or fubtradlion effettual, in exterminating one of the unknown quantities, or otherwife promo¬ ting the folution. Subftitutions may be made of the values of quantities, in place of quantities themfelves, and various other fuch contrivances may be ufed, which will render the folution much lefs complicated. (See Ex. 3. 7. and 9.) Sect. II. General Solution of Problems. In the folutions of the queftions in the preceding E B R A. 411 part, the given quantities (being numbers) difappear Of EqUa. in the laft conclufion, fo that no general rules for like dons, cafes can be deduced from them. But if letters are ufed to denote the known quantities, as well as the unknown, a general folution may be obtained, becaufe, during the whole courfe of the operation, they retain their original form. Hence alfo the connexion of the quantities will appear in fuch a manner as to difcover the neceffary limitations of the data, when there are any, which is effential to the perfect folution of a pro¬ blem. From this method, too, it is eafy to derive a fynthetical demonftration of the folution. When letters, or any other fuch fymbols, are em¬ ployed to exprefs all the quantities, the algebra is fome¬ times called Jpecious or literal. Ex amp. 8.

This is necef- fary to give pofitive values of x, y, and z, which alone can take place in this queftion. Befides, if x, y, and z be affumed as any known numbers whatever, and if values of a, b, and c be deduced from fteps 7th, 8th, and 9th, of the preceding operation, it will appear, that a, by and c will have the property required in the limitation here mentioned. If a, by and c were fuch, that any of the quantities, Xy y, or z, became equal to o, it implies that one of the agents did nothing in the work. If the values of any of thefe quantities be negative, the only fnppofi- tion which could give them any meaning would be, that fome of the agents, inftead of promoting the ■work, either obftru&ed it, or undid it to a certain ex¬ tent.

This limita¬ tion appears alfo from the nature of the queftion, as the fecond courier muft travel at a greater rate than the firft, in order to overtake him. For the rate of the firft courier is to the rate of the fecond as £ to —, , • 9 J that is, as ps to qr ; and therefore qr muft be greater than ps. Scholium. Sometimes when there are many known quantities in a general folution, it may fimplify the operation to exprefs certain combinations of them by new letters, ftill to be confidered as known. CHAP. IV. Of Involution and Evolution. In order to refolve equations of the higher orders, it is neceffary to premife the rules of Involution and Evolution. The reciprocals of the powers of a quantity may be expreffed by that quantity, with negative exponents of the fame denomination. That is, the feries ay 1, —> —> ~y See. may be exprefied by aJ, a°ya—t, a—% a—3, a—m. See. For the rule for dividing the powers of the fame root was to fubtradf the exponents; if then the index of the divifor be greater than that of the dividend, the index of the quotient muft be negative. Thus, — z: -3=n—Alfo, ^=-1. —-—am—m — a?. And, — = 1. and fo on of others. am am Cor. 1. Hence any quantity which multiplies either the numerator or denominator of a fraction, may be tranfpofed from the one to the other, by changing the fign of its index. Thus, —zzxv—1. And —f—, &c. y ' y3 y3*—1 Cor. 2. From this notation, it is evident that thefe negative powers, as they are called, are multiplied by adding, and divided by fubtrading their exponents. Thus, a—aX«—%—a—y. Or, _Lx-1 =-=*—*. -zzax Or, aiJa\a I. Of 5 A L G E BRA, Part I. Of Involu¬ tion and Evolution. I. Of Involution. To find any power of any quantity is the bufinefs of involution.

The exponents of the letters may not be multi¬ ples of the index of the root, and then they become fradlions ; and when the root of the coefficient cannot be extracted, it may alfo be expreffed by a fractional exponent, its original index being underftood to be I. Thus, ViGa’b1 3 V'y-zx3 = 7t«tx = 3 v' 7 XaTx. As evolution is the reverfe of involution, the reafon of the rule is evident. The root of any fra&ion is found by extracting that root out of both numerator and denominator. Cafe II. When the quantity is compound. 1. To extraCt the fquare root. Rule. 1.

The fquare root is to be extrafted out of the firft term (by preceding rules), which gives the firft part of the root fought. SubftraA its fquare from the given quantity, and divide the firft term of the re¬ mainder by double the part already found, and the quotient is the fecond term of the root. Thus, in this example, the remainder is iah + b11 ; and iab being divided by the double of the part found, gives -\-b for the fecond part of the root. 3. Add this fecond part to double of the firft, and multiply their fum by the fecond part: Subtract the produtt from the laft remainder, and if nothing re¬ main, the fquare root is obtained. But, if there is a remainder, it muft be divided by the double of the parts already found, and the quotient would give the third part of the root; and fo on. In the laft example, it is obvious, that <7-}-£ is the fquare root fought. The entire operation is as follows. a'1 -\-2ab-\-bz fa-\-b za + bX + zab + b1 Xb) zab+b1 The reafon of this rule appears from the compofi- tion of a fquare. BRA. Part L In evolution it will often happen, that the opera- 9f Solu¬ tion will not terminate, and the root will be exprefled by a feries. w Thus, the fquare root of a1 -J-x1 becomes a feries. x1 x4 x6 5T'+ T-s> &c* k ' 1 2« 8a3 1 i6as’ x6 x8 * + 8^-6^’ &c* The extraction of roots by feries is much facilitated by the binomial theorem (Chap. vi. Se&. 3.) By fi- milar rules, founded on the fame principles, are the roots of numbers to be extracted. III. Of Surds. Def. Quantities with fractional exponents are call ed furds, or imperfecl powers. Such quantities are alfo called irrational; in oppo- fition to others with integral exponents, which are called rational. Surds may be expreffed either by the fractional ex¬ ponents, or by the radical fign, the denominator of the fraCtion being its index; and hence the orders of furds are denominated from this index. In the following operations, however, it is generally convenient to ufe the notation by the fractional expo¬ nents. 2. To extraCt any other root. — Va. V^abx — iba*. V—cPb'*. Rule. Range the quantity according to the dimen- fions of its letters, and extraCt the faid root out of the firft term, and that ftiall be the firft member of the root required. Then raife this root to a dimen- fion lower by unit than the number that denomi¬ nates the root required, and multiply the power that arifes by that number itfelf. Divide the fecond term of the given quantity by the produCt, and the quotient fhall give the fecond member of the root required.—In like manner are the other parts to be found, by confidering thofe already got as making one term. Thus, the fifth root of . 5*4 ) 5a*h And tf-f-3 raifed to the 5th power is the given quan¬ tity, and therefore it is the root fought. The operations concerning furds depend on the fol¬ lowing principle : If the numerator and denominator of a fractional exponent be both multiplied or both di¬ vided by the fame quantity, the value of the power is the fame. Thus an=zani; : for let an zab \ then amzzbn, and amczzbnc, and extracting the root nc, anc ~bnc —bzza'1. Lem.

If they are furds of different rational quantities, let them be brought to others of the fame denomina¬ tion, if already they are not, by prob. 1. Then, by multiplying or dividing thefe rational quantities, their produft or quotient may be fet under the com¬ mon radical fign. Thus, Vbzasa b ~\/anbm v a+b ~s/u dTb* , , , , ~aJF~a Tb r~a V6~ , V ab* If the furds have any rational coefficients, their produft or quotient muft be prefixed. Thus, The application of the rules of this chapter to the refolving of equations, fhall be explained in the fucceed- ing chapters, which treat of the folution of the differ¬ ent claffes of them ; but fome examples of their ufe in preparing equations for a folution are the following. If a member of an equation be a furd root, then the equation may be freed from any furd, by bringing that member firft to hand alone upon one fide of the equa¬ tion, (and then taking away the radical fign from it, and raifing the other fide to the power denominated by the index of that furd. This operation becomes a neceffary fiep towards the folution of an equation, when any of the unknown quantities are under the radical fign. Example. If 3 Vx2 —a1 -+-2j~a-j-y Then 3V/x1—a2 —a—y and 9XX2—a2=.al—zay-^-y* If the unknown quantity be found only under the radical fign, and only of the firlt dimenfion, the equa¬ tion will become fimple, and may be refolved by the preceding rules. Thus, if 3 V^-f-16 + 5 = 9 Then 3V/4x+i6=4 And 4^ -f-16 = 64 4^=48 And x = 12 a n—abufmn. It is often convenient, in the operations of this problem, not to bring the furds of fimple quantities to the fame denomination, but to exprefs their produCt or quotient without the radical fign, in the fame manner as if they were ra¬ tional quantities. Thus, the produft in Ex. 1. may be ambn, and the quotient in Ex. 3. cT^b^ Cor. If a rational coefficient be prefixed to a radical fign, it may be reduced to the form of a furd by the lemma, and multiplied by this problem ; and converfe- ly, if the quantity under the radical fign be divifible by a perfeCI power of the fame denomination, it may¬ be taken out, and its root prefixed as a coefficient. a\/b~Va'‘b} = 3y'8/V. Conv. Va2b* ■=aab*/b }*/\a2—'Ota'1 bzz. 2aV 1—zb. Even when the quantity under the radical fign is not divifible by a perfeft power, it may be ufeful fome- times to divide furds into their component fa&ors, by reverfing the operation of this problem. Thus Vab — Va X a2b—bx2Vba—bx xVa+x=£fxV^xV^F. If mVa2x—b2x =a Then a2x—blx=a’n If the unknown quantity in a final equation has fractional exponents, by means of the preceding rules a new equation may be fubftituted, in which the ex¬ ponents of the unknown quantity are integers. Thus, if x2+ 3xT= 10, by reducing the furds to the fame denomination, it becomes xt+3x^=io; and if z=xT, then z3-f-3z4 = 10 ;-and if this equa¬ tion be refolved from a value of z, a value of x may be got by the rules of the next chapter. Thus alfo, if x + 2x2—3xt=ioo. If x7=zz, this equation be¬ comes Zfi + 2Z3—3Z2 = 100. p m In general, if x-+x—= pofing the above mentioned half coefficient, a value of the unknown quantity is obtained in known terms, and therefore the equation is refolved. The reafon of this rule is manifeft from the compo- fition of the fquare of a binomial, for it confifts of the fquares of the two parts, and twice the product of the two parts. [Note, at the ertd of Chap. IV.) The different forms of quadratic equations, expref- fed in general terms, being reduced by the firil and fe* cond parts of the rule, are thefej Cafe 3. Of thefe cafes it may be obferved, 1. That if it be fuppofed, that the fquare root of a pofitive quantity may be either poiitive or negative, ac¬ cording to the moft extenfive ufe of the iigns, every quadratic equation will have two roots, except fuch of the third form, whofe roots become impoffible. 2. It is obvious, that, in the two firit forms, one of the roots muff be pofitive, and the other negative. 3. In the third form, if or the fquare of half 4 the coefficient of the unknown quantity, be greater than b1, the known quantity, the two roots will be poii¬ tive. If —be equal to 31, the two roots then be- V 4 come equal. But if ift this third cafe — is lefs than b*, the 4 quantity under the radical iign becomes negative, and the two roots are therefore impoffible. This may be eafily fliown to arife from an impoffible fuppolition in the original equation. • 4. If the equation, however, exprefs the relation of magnitudes abltraftly confidered, where a contrariety cannot be fuppofed to take place, the negative roots cannot be of ufe, or rather there are no fuch roots} Vol I. Part II. and thefe are the fame two pofitive E B R A. 417 for then a negative quantity by itfelf is unintelligible, Equation*. and therefore the fquare root of a pofitive quantity " muff be pofitive only. Hence, in the two firft cafes, there will be only one root; but in the third, there will be two. For in this third cafe, x*—ax——5*, or ax—x1 = £1, it is obvious that X may be either greater or lefs than ^a, and yet a x may be pofitive; and hence «—xX.x = ax—x* may alfo be pofitive, and may bf equal to a given pofitive quantity b'1: therefore the fquare root of xJ—ax-\-^a’1 may be either x—£4* or -la—x, and both thefe quantities alfo pofitive. Let then /——b\ Alfo k x=-— / f b\ 2 V 4 roots as were obtained by the general rule. The general rule is ufually employed, even in que- ftions where negative numbers cannot take place, and then the negative roots of the two .firft forms are ne¬ glected. Sometimes even only one of the pofitive roots of the third cafe can be ufed, and the other may be ex¬ cluded by a particular condition in the queftion. When an impoffible root arifes in the folution of a queftion, and if it be refolved in general terms, the neceffary li¬ mitation of the data will be difcovered. When a queftion can be fo Hated as to produce a pure equation, it is generally to be preferred to an ad- fedfed. Thus the queftion in the preceding feftion, by the moft obvious notation, would produce an adfe&ed equation. 2. Solution of Shieflions producing Quadratic Equations. The expreffion of the conditions of the queftioh by equations, or the ftating of it, and the reduction like- wife of thefe equations, till we arrive at a quadratic e- quation, involving only one unknown quantity and its fquare, are effected by the fame rules which were given for the folution of fimple equations in Chap III.

For as the fum of the firft and fecond is 10, 25 can¬ not be one of them: 2 therefore is the firft, and the proportionals will be 2, 8, 32. This reftri&ion will alfo appear from the explana¬ tion given of the third' form, to which this equation belongs. For z may be lefs than 11, but from the firft condition of the queftion it cannot be greater; hence the quantity z*—27Z-J-12 can have only one i 2 I fquare root, viz. 11—z‘, and this being put equal to we have by tranfpofition z=——— = 2, 4 _ 2 . 2 which gives the only juft folution of the queftion.

When a number of quantities increafe or de- creafe by the fame common, difference, they form an arithmetical feries. Thus, a,'a+b, a+ 21, a + $b, &c. x, x—b, x—zb, &c.

The fum of a geometrical feries wanting '~~*v the firft term, is equal to the fum of all but the laft term multiplied by the common ratio. For, aftuming the preceding notation of a feries, it is plain, that It is plain, that the terms in the fame perpendicular rank are equally diftant from the extremes; and that the fum of any two in it is tf+.v,. the fum of the firft and laft. Cor. i. Hence the fum of all the terms-of an arith¬ metical feries is equal to the fum of the firft and laft, taken half as often as there are terms; Therefore if n be the number of terms, and s the fum of the feries; Xj If a=o, then / = Cor. z. The fame notation being underftood, fince any term in the feries confifts of a, the firft term, to¬ gether with b taken as often as the number of terms preceding it, it follows, that x — a-\-n—iX£, and hence j = —iX&X —; or by multiplication, r — zan+n'b—nb _ 4 Therefore from the firft term, the common difference, and number of terms being given, the fum may be- found. Ex. Required the fum of 50 terms of the feries 2, 4, 6, 8, &c. 2X2Xco-4-eo,X2^—50X2 cioo J= 2“ = -^-=2550. Cor. 3. Of the firft term, common difference; firm and number of terms, any three being given, the fourth may be found by refolving the preceding -equa¬ tion ; a, b, s, and n, being fucceffively confidered as the unknown quantity. In the-three firft cafes the equation is fimple, and in the laft it is quadratic. II. Of Geometrical Series. Def. When a number of quantities-increafe by the fame multiplier, or decreafe by the fame divifor, they form a geometrical feries.. This common multiplier or divifor is called the common ratio. a a a Thus, a, ar, ar2, &c. a, —, t, &c. 1, z, 4, 8, See. Prop. I. The produtt of the extremes in a geome¬ trical feries is equal to the product of any two terms, equally diftant from the extremes. JLet a be the firft term, y the laft, r the common ra¬ tio : then the- feries is, a, ar, ar2, ar*, ar*, &c.

Therefore s being the fum of the feries, > a , yr~-a j—yXrzzs—a. And s=:jy^- Hence s can be found from a, y, and r; and any three of the four being given, the fourth may be found-- Cor. 2. Since the exponent of r in any term is equal to the number of terms preceding it; hence in the laft term its exponent will be n— 1 ; the laft term, there- £ort,y—ar , and s—- - " ■■ Hence of thefe four; /, a, r, n, any three being given, the fourth may be found by the folution of equations. If n is not a fmall number, the cafes of this problem will be moft conveniently, refolved by logarithms; and of ffleh folutions there are examples in the appendix to this part. Cor. 3. If the feries decreafes, and the number of terms is infinite ; then, according to this notation, a the leaft term* will be o, . and a finite fum. Ex. Required the fum of the feries x, 4-, -g-, &c, to infinity. I X2 Here^=x, and r—z. Therefore s= 22_1==2.

Of Infinite Series. It was obferved (Chap. I. and IV.), that in many cafes, if the divifion and evolution of compound quan¬ tities be actually performed, the quotients and roots can only be expreffed by a feries of terms, which may, be continued ad infinitum. By comparing a few of the firft terms, the law- of the progrelfion of fuch a fe- A L G E ries will frequently be difcovered, by which it be r continued without any farther operation. When this "j cannot be dong, the work is much facilitated by feve- ral methods; the chief of which is that by the binomial theorem. Theorem, dny binomial {at a +b) may he raifed to any power (m) by the following rules. x. From infpedfing a table of the powers of a bino¬ mial obtained by multiplication, it appears that the terms vyithout their coefficients arg am, am—'b, am—1bi, &c. ' ' 2. The coefficients of thefe terms will be found by the following rule. Divide the exponent of a in any term by the exponent of b increafed by i, and the quotient multiplied by the coefficient of that term will givg the epefficient of the next following term. This rule is found, upon trial in the table of powers, to hold imiverfally. The coefficient of the iirft terms is always i. and by applying the general rule now pro- pofed, the coefficients of the terms in order will be as m—i m—i.. m-r-2 follows: i, m} m%—-—, nfA : : ~ X——, &c.

It is deduced here by indudfion only; but it may be rigidly demonftrated, though upon principles which do not belong to this place. • Cor. 1. As m may denote any number, integral or fractional, poiitive or negative ; hence the diviiioh, in¬ volution, and evolution, of a binomial, may be performr ed by this theorem. £x. I.

This theoi'em may be applied to quantities which confift of more than two parts, by fuppofing them diftinguiffied into two, and theiv fubftituting fpr the powers of thefe compound parts their values, to be obtained alfo, if required, from the theorem. Thus, a+bfc^—a-y-b+c*. Scholium. An infinite feries may itfelf be multiplied or divided by another; it may be involved or evolved; and va¬ rious other operations may be performed upon it which are necefiary in the higher parts of algebra. The me¬ thods fpr finding the fum depend upon other prin¬ ciples. IV. Properties of Numbers. Theor. I. The fum of two quantities multiplied by their difference is equal to the difference of their Jquflres. Let the quantities be reprefented by a and b, then a + bXa—rbszd1—b1, as appears by performing the operation. Cor. If a and b be any two quantities of which the fum may be denoted by s, the difference by d, and their product by p, then the following propolitions will be true. 2. a*—b*—sd 4. a1—P—s'd—dp 6. a*—b*—s>d—isdp, &c« ries, fince - 1X1- , let a £=—r, and m——i; and the fame feries will arife as was obtained by diviiion (Chap.

The quotient will be rn x-\-rn % See. till the in¬ dex of r be o, and then the laft term of it will be 1 ; for if this feries be multiplied by the divifor r—i , it will produce the dividend rn-—t. It will appear alfo by performing the divifion, and inferting for n any number. Lem. 2. Let r be any number, and n any integer odd number, r”+1 is divifible by r-}- 1. Alfo, if n is arty even number, rn—1 is divifible by r-j-i. The quotient in both cafes is r11" 1—rn—I-f- rn—3 exponent of r be o, and the laft term r°~i. If this feries confift of an odd number of terms, and be muli^ died by rft-1 the divifor, the produa is r"-|~i the dividend. If the feries confift of an even number of terms, the produa is r”— 1; but it is plain that the number of terms will be odd only when n is odd, and even only when n is even. The conclufion will be manifeft by performing the divifion. Lem. 3. If r is the root of an arithmetical fcale, any number in that fcafe may be reprefented in the fol¬ lowing manner, a, b, c, &c. being the coefficients of digits, a-\.br-\-crz-{-dr'3, See. Theor. IV. If from any number in the general fcale now deferibed, the furn of its digits be fubt rafted, the remainder is divifible by r— 1. The number is a+br+cr* -{-dr}, &c. and the fum of the digits is a-\-b-\-c^-d, 8tc. Subtraaing the lat¬ ter from the former, the remainder is br—b-\-cr,‘— c+dr1—d. See. —brX—i-brXr* — i+^/Xr3—i,&c. But (by Lem. 1.) r”— t is divifible by r—t, whatever integer number » may be, and therefore any multiple of rn—1 is alfo divifible by r— t: Hence each of the terms, bXr—i,cXrz— , &c. is divifible by r—I, and therefore the whole is divifible by r— 1. Cor. 1. Any number, the fum of whofe digits is di¬ vifible by r— 1, is itfelf divifible by r— 1. Let the number be called N, and the fum of the digits D; then by this prop. N—D is divifible by r— 1, and D is fup- pofed to be divifible by r— 1; therefore it is plain that N muft alfo be divifible by r— 1. Cor. 2. Any number, the fum of whofe digits is di¬ vifible by ah aliquot part of r— 1, is alfo divifible by that aliquot part. For, let N and D denote as before; and fince N—D (Theor. 4.) is divifible by r—1, it is alfo divifible by an aliquot part of r— 1 ; but D is di¬ vifible by an aliquot part of r—1, therefore N is alfo divifible by that aliquot part. from the former, and the remainder added to the given number, it makes br-\-b-\-cr’1 — c-h/r3-j-be direttly as Y and Z, joint¬ ly; or X is faid to be as Y and Z. hr it follows, For fine.

If the two fides of a proportional equation be both multiplied, or both divided by the fame quan¬ tity, it will continue to be true. iftt If the quantity be conftant, it is manifeft from Prop. 1. zd. If the quantity be variable, let Xzz Y, and Z a variable quantity, then XZ—YZ. For, fince X~Y, (Def. 2.)

Let the preceding notation of proportion be fince X:x:: Y:y : : Z s z. (Chap. II.) Y:y;:Xdt=Z ; x=t=z, therefore Def. 5. Yj= XztzZ. Cor. Hence, one fide of a proportional equation will be as the fum, or as the difference of the two fides 4 and the fum of the two fides will be as their difference. Thus, if X=r+Z, then X+ Y+Z and X=X —Y—Z, and alfo X+Y+Z=zX—Y~Z. Prop. 4. If the two fides of a proportional equation called a proportional equation (a), the equations for- be refpeaively multiplied or divided by the two fides merly treated of being in this place, for the fake of 0f any other proportional equation, the produfts or diftin&ion, called abfolute. quotients will form a proportional equation.

The experiments by which the principles are afcertained admit of vari- v 1 ous degrees of accuracy; and on the degree of phyfical accuracy in the principles will depend the phyfical ac¬ curacy of the conclufions mathematically deduced* from them. If the principles are inaccurate, the conclufions muft, in like manner, be inaccurate; and, if the limits of inaccuracy in the principles can be afcertained, the correfponding limits, in the conclufions derived from them, may likewife be calculated. Examp. 1. Let a glafs tube, 30 inches {a') long, be filled with mercury, excepting 8 inches [b); and let it be inverted as in the Toricellian experiment, fi» that the 8 inches of common air may rife to the top: It is required to find at what height the mer¬ cury will remain fufpended, the mercury in the ba-s rometer being at that time 28 inches («/) high. The folution of this problem depends upon the fol¬ lowing principles: 1. The preffure of the atmofphere is meafured by the column of mercury in the barometer; and the ela- * | flic force of the air, in its natural ftate, which refills, this prefiure, is therefore meafured by the fame co¬ lumn. T. If there be two variable phyfical quantities, ei¬ ther of the fame, or of different kinds, which are fo connected, that when the one is increafed or diminilh- ed, the other is increafed or diminifhed in the fame proportion; or, if the magnitudes of the one, in any two fit nations, have the fame ratio to each other, as the magnitudes of the other in the correfponding fitua- tions, the relation of the mathematical meafure of thefe quantities may be expreffed by a proportional equa¬ tion, according to Def. x. 2. If two variable phyfical quantities be fo connec¬ ted, that the one increafes in the fame proportion as the other is diminilhed, and converfely ; or, if the mag¬ nitudes of the one, in any two fituations, be recipro¬ cally proportional to the magnitudes of the other, in the correfponding fituations, the relation of their mea- fures may be expreffed by a proportional equation, ac¬ cording to Def. 2. 3. If three variable phyfical quantities are fo connec¬ ted, that one of them is increafed or diminilhed, in proportion as both the others are increafed or diminilh¬ ed; or, if the magnitudes of one of them, in any two fituations, have a ratio which is compounded of the ra¬ tios of the magnitudes of the other two, in the corre¬ fponding fituations; the relation of the meafures of thefe three may be expreffed by a proportional equa¬ tion, according to Def. 3. .4. In like manner may the relations of other com¬ binations of phyfical quantities be expreffed according to Def. 4. And when thefe proportional equations are obtained, by reafoning with regard to them, ac¬ cording to the preceding propofitions, new relations of the phyfical quantities may be deduced. 2. Examples of Phyfcal Problems. The ufe of algebra, in natural philofophy, may be properly illuftrated by fome examples of phyfical pro¬ blems. The folution of fuch problems muft be derived from known phyfical laws, which, though ultimately 2. In different ftates, the elaftic force of the air is reciprocally as the fpaces which it occupies. 3. In this experiment, the mercury which remains fufpended in the tube, together with the elaftic force of the air in the top of it, being a counterbalance to the preffure of the atmofphere, may therefore be ex- preffed by the column of mercury in the barpmeter. Let the mercury in the tube be x inches, the air in the top of it occupies now the fpace a—x; it occupied formerly b inches, and its elaftic force was d inches of mercury: Now,therefore,the force muft be(#—x-.b wd:) Jli!— inches.

One of the roots 44 is plainly excluded in this cafe, and the other, 14, is the true anfwer. If the column of mercury x, fufpended in the tube, were a counterba¬ lance to the preffure of the atmofphere, expreffed by the height of the barometer d, together with the mea¬ fure of the elaftic force of b inches of common air in the fpace x—a, that is, if x=d or x= x—a x — a d, the equation will be the fame as before, and the root 44 would be the true anfwer. But the experiment in this queftion does not admit of fuch a fuppofition. Examp. 2. The diftance of the earth and moon (, R, t, /, any three being gi¬ ven the 4th may be found. When t is not very fmall, the folution will be obtained moft conveniently by lo¬ garithms. When R is known r may be found, aod converfely. Ex.

III. Of Annuities. An annuity is a payment made annually for a cer¬ tain term of years, and the chief problem with regard to it is, * to determine its prefent worth.’ The fup- pofition on which the folution proceeds is, that the money received by the feller, being improved by him in a certain manner during the continuance of the an¬ nuity, amounts to the fame fum as the feveral payments received by the purchafer, improved in the fame man¬ ner. The fuppofitions with regard to the improve¬ ment may be various. What is called the method of Jtmple inter eft, in which fimple intereft: only is reckon¬ ed upon the purchafe-money, and fimple intereft on each annuity from the time of payment, is fo manifeftly un¬ equitable, as to be univerfally rejefted ; and the fuppo- fition which is now generally admitted in praftice, is the higheft improvement poffible on both fides, viz. by compound intereft. As the taking compound intereft is prohibited by law, the realizing of this fuppofed im¬ provement requires punctual payment of intereft, and therefore the intereft in fuch calculations is ufually made low. Even with this advantage, it can hardly be rendered effectual in its full extent; it is however univerfally acquiefced in, as the moft proper founda¬ tion of general rules; and when peculiar circumftances require any different hypothefis, a fuitable calculation may be made. Let then the annuity be called a, and let p be the prefent worth of it or purchafe-money, t the time of its continuance, and let the other letters denote as for¬ merly. The feller, by improving the price received p, at compound intereft, at the time the annuity ceafes, has The purchafer is fuppofed to receive the firft annui¬ ty a at the end of the-firft year, which is improved by him for t—I years; it becomes therefore (Th. 2.) qR' — '.

The calculations of life annuities, depend partly up¬ on the principles now explained, and partly on phyfi- cal principles, from the probable duration of human life, as deduced from bills of mortality. PART Part It ALGEBRA* PART II. 429 Of the General Properties and Refolution of Equations of all Orders. CHAP. I. Of the Origin and Compofition of Equations; and of the Signs and Coefficients of their Terms. IN order to refolve the higher orders of equations, and to inveftigate their general affections, it is pro¬ per firfl to confider their origin from the combination of inferior equations. As it would be impoffible to exhibit particular rules for the folution of every order of equations, their num¬ ber being indefinite ; there is a necefiity of deducing rules from their general properties, which may be equal¬ ly applicable to all. In the application of algebra to certain fubjedts, and efpecially to geometry, there may be an oppofition in the quantities, analogous to that of addition and fub- tradtion, which may therefore be expreffed by the figns + and —. Hence thefe figns may be underftood by ^bftra&ion, to denote contrariety in general; and therefore, in this method of treating of equations, ne¬ gative roots are admitted as well as pofitive. In many cafes the negative will have a proper and determinate meaning ; and when the equation relates to magnitude only, where contrariety cannot be fuppofed to exift, thefe roots are negledled, as in the cafe of quadratic equations formerly explained. There is befides this advantage in admitting negative roots, that both the properties of equations from which their refolution is obtained, and alfo thofe which are ufeful in the many extenfive applications of algebra, become more Ample and general, and are more eafily deduced. In this general method, all the terms of any equation are brought to one fide, and the equation is expreffed by making them equal to o. Therefore, if a root of the equation be inferted inftead of (x) the unknown .quantity, the pofitive terms will be equal to the nega¬ tive, and the whole muft be equal to o. l)ef. When any equation is put into this form, the term in which (x) the unknown quantity, is of the higheft power, is called the Firf; that in which the index of x is lefs by 1, is the Second, and fo on, till the lalt into which the unknown quantity does not enter, and which is called the jdbfoluteTzrm. Prof . I. If any number of equations be multiplied together, an equation will be produced, of which the dimenfion (a) is equal to the fum of the dimenfions of the equations multiplied. If any number of Ample equations be multiplied to¬ gether, as x—a—o, x—bzzo, x—c—o, &c. it is obvi¬ ous, that the produft will be an equation of a dimen- fron, containing as many units as there are fimple equa¬ tions. In like manner, if higher equations are multi¬ plied together, as a cubic and a quadratic, one of the fifth order is produced, and fo on. Converfely. An equation of any dimenfion is confi- dered as compounded either of fimple equations, or of others, fuch that the fum of their dimenfions is equal to the dimenfion of the given one. By the refolution of equations thefe inferior equations are difcovered, and by inveftigating the component fimple equations, the roots of any higher equation are found. Cor. 1. Any equation admits of as many folutions, or has as many roots as there are fimple equations which compofe it, that is, as there are units in the di¬ menfion of it. Cor. i. And converfely, no equation can have more roots than the units in its dimenfion. Cor. 3. Imaginary or impoffible roots muft enter art- equation by pairs ; for they arife from quadratics, in which both the roots are fuch. Hence alfo,, an equation of an even dimenfion may have all its roots, or any even number of them impof¬ fible, but an equation of an odd dimenfion mult at leafi: have one poffible root. Cor. 4. The roots are either pofitive or negative, according as the roots of the fimple equations, from which they are produced, are pofitive or negative. Cor. 5. When one root of an equation is difcovered, one of the fimple equations is found, from which the given one is compounded. The given equation, there¬ fore, being divided by this fimple equation, will give an equation of a dimenfion lower-by 1. Thus, any equation may be depreffed as many degrees as there are roots found by any method whatever. Prop. II. To explain the general properties of the figns and coefficients of the terms of an equation. Let *•—a—o, x—fc=o, x—c—o, x—d-zzo, &c. be fimple equations, of which the roots are any pofitive quantities -f #, -\-b, -\-c, -\-d, &c. and let x-\-m=.0, x+n—o, &c. be fimple equations, of which the roots are any negative quantities —m,—n, &c. and let any number of thefe equations be multiplied together,,as in the following table t x—azzo Xx—b=zo ~XZZ+ai 5 =or a Quadratic, X.v—c—o (a) The term dimenfion, in this treatife, is ufed in fenfes fomewhat different, but fo as not to create any ambiguity.

The reafon of tfiis is derived from the compofition of the coefficients of thefe terms, which confift of combinations of odd numbers-of the roots, as explain¬ ed in the preceding Chapter. Prop. 2. An equation may be transformed into another that fhall have its1 roots-greater or lefs than the roots of the given equation by fome given difference. Let x' be ' the unknown quantity of the equation, and e the given-difference ; let y=x2±2—o, and e—\p, which being fubftituted for e, the new equation will want the fecond term. And univerfally, the coefficient of the firft term of a cubic equation being 1, and x being the unknown quantity, the fecond term may be taken away by fuppofing x—yz+z\p,z±zp being the coefficient of that term. Cor. 2. The fecond term may be taken away by the folution of a fimple equation, the third by the folution of a quadratic, and fo on. Cor. 3. If the fecond term of a quadratic equation be taken away, it will become a pure equation, and thus a folution of quadratics will be obtained, which coincides with the folution already given in Part I. Cor. 4. The laft term of the transformed equation is the fame with the given equation, only having e in place of x. Prop. 3. In like manner may an equation be trans¬ formed into another, of which the roots (hall be equal to the roots of the given equation, multiplied or di¬ vided by a given quantity. Let x be the unknown letter in the given equation, and y that of the equation wanted ; alfo kt e be the given quantity. To multiply the roots let xe~y, and x—JL, To divide the roots let ~~y, and x—ye. The* Part IF. Then fubftltute for x and its powers, or ye and e its powers, and the new equation of which y is the unknown quantity will have the property required. Cor. i.

If the roots of any of thefe transformed equations be found by any method, the roots of the original equation, from which they were derived, will eafily' be found from the fimple equations expreffing their re-- lation. Thus, if 8 is found to be a root of the trans¬ formed equation 23 + 23s—696 = 0 (Cor. 2. prop. 3.) Since the cbrrefponding root of the given- ——r=o, ory*—py1 -\~qay—a^r—o.

If the two transformations in Prop,. 2. and 3. be both required, they may be performed either feparately or together. Thus, if it is required to transform- the equation /ix3—px1 -\-qx—r=o into one which fhall want the fecond term, and in which the coefficient of the lirft term fhall be 1 •; let x=-, and theny3—A1 + qay— equation 5x3—6xt+7x—30=0 muilbeli!=2. It is to be obferved alfo, that the reafoning in Prop. 2. and 3. and the corollaries, may be extended to any or¬ der of equations, though in them it is applied chiefly to cubics. CHAP. III. Of the Refolution of Equations. From the preceding principles and operations, rulesr ' may be derived for refolving equations of all orders.. i*V=o as before ; then let and the new- equation, of which z is the unknown quantity, will want the fecond term, and the coefficient of z3, the higheft term is 1. Or, if x=the fame equa¬ tion as the laft found will arife from one operation. Ex. Let the equation >be 5X3—6x1-j-7x—30=0. If x=£, theny'3—Oy'+lSy—750=0. And if y— Zr\-2, z3-f 230—696=0. Alfo, at once, let x= , and the equation propqrly reduced, by bring¬ ing all the terms to a common denominator, and thetr cafting it off, , will be z3-4-23z—696 = 0, as before. Cor. 3. If there are fractions in an equation, they may be taken away, by multiplying the equation by the denominators, and by this propofition the equa¬ tion may then be transformed into another, without fractions, in which the. coefficient of the firft term is 1. In like manner may a furd coefficient be taken away in certain cafes. Cor. 4. Hence alfo, if the coefficient of the fecond term of a cubic equation is not divifible by 3, the fractions thence ariling in the transformed equation, wanting the fecond term, may be taken away by the preceding corollary. But the fecond term alfo may be taken away, fo. that there fhalLbe nafuch fraftions in the transformed equation, by fuppofing x=5rfc£, r±rp being the coefficient of the fecond term of the given, equation. And if the equation ax3—px2 ^-qx—r — o be given, in which p is not divifible by 3, by fuppofirig x = Alh£, the transformed equation reduced is z3— 3a ^p1 -\-9aq.Xz—2p3^~9apq—274+4qy24-4°3 ^._4°5 - X y v44-40>,24-40Q _ 405 y* ~ y Mult, and tranfp. 44+40/—40544-400=0.

If any two numbers, being inferted for Of Equa- the unknown quantity (x) in any equation, give re-, c:Hns‘ , fults with oppofite figns, an odd number of roots muff " ',r~v be between thefe numbers. This appears from the property of the abfolute term, and from this obvious maxim, that if a number of quantities be multiplied together, and if the figns of an odd number of them be changed, the fign of the produdt is changed. For, when a pofitive quantity is inferted for x, the refult is the abfolute term of an equation whofe roots are lefs than the roots of the gi¬ ven equation by that quantity (Prop. 2. Cor. 3. Chap. II.^ If the refult has the fame fign as the given ab¬ folute term, then from the property of the abfolute term (Prop. 2. Chap. I.) either none or an even num¬ ber only of the pofitive roots, have had their figns changed by the transformation; but if the refult has an oppofite fign to that of the given abfolute term, the figns of an odd number of the pofitive roots muff have been changed. In the firlt cafe, then, the quantity fubftituted muff have been either greater than each of an even number of the pofitive roots of the given equa¬ tion, or lefs than any of them ; in the fecond cafe, it muff have been greater than each of an odd number of the pofitive roots. An odd number of the pofitive roots, therefore, muff lie between them when they give refults with oppofite figns. The fame obfervation is to be extended to the fubftitution of negative quan¬ tities and the negative roots. From this lemma, by means of trials, it will not be difficult to find the neareft integer to a root of a given numeral equation. This is the firft ftep towards the approximation ; and both the manner of continuing it, and the reafon of the operation, will be evident from the following example. Let the greater be and the lefs x—4. Then x4^24-k—y^=2xl4-242:=2o8 Hence 42c=i 04—x* Alfo x-\-yl3 4- x^/yl s—2 x 2 40 Subftitute for4* its value and 2x34*624x—6x3=2 240. This reduced gives x3—156x4-5602=0. The roots of this equation are 4-10, 4-4, —14. If x=:jo, then 42=2; and the numbers fought are 12 and 8, which give the only juft folution. If x—4, then 42=:88 and y—/88. The numbers fought are there¬ fore 44-V^88 and 4—88. The laft is negative, but they anfwer the conditions. Laftly, if xc=— 14, then 41——92, hence y—*/—92, is impoffible; but ftill the two numbers——92, —14—92, be¬ ing inferted, would anfwer the conditions. But it has been frequently obferved, that fuch folutions are both ufelefs and without meaning. IV. Solution of Equations by Approximation. By the former rules, the roots of equations, when they are commenfurate, may be obtained. Thefe, however, more rarely occur; and when they are in- fcommenfurate, we can find only an approximate value of them, but to any degree of exadtnefs required. There are various rules for this purpofe; one of the moft fimple is that of Sir Ifaac Newton, which ffiall be now explained. Voi I. Part II. Let the equation be x3—2x—5=0. 1. Find the neareft integer to the root. In this cafe a root is between 2 and 3 ; for thefe numbers being inferted for x, the one gives a pofitive, and the other a negative, refult. Either the number above the root, or that below it, may be affumed as the firft value; only it will be more convenient to take that which ap¬ pears to be neareft to the root, as will be manifeft from the nature of the operation. 2.

Of the Application of Algebra to GecIme.try. . CHAP. I. General Principles. GEOMETRY treats both of the magnitude and pofition of extenfion, and their connections. Algebra treats only of magnitude; therefore, of the relations which fubfift in geometrical figures, th'ofe of magnitude only can be immediately expreffed by algebra. The oppofite pofition of ftraight lines may indeed be expreffed fimply by the figns + and —. But, in order to exprefs the various other pofitions of geome¬ trical figures by algebra from -the principles.of geome¬ try, fome relations of magnitude mull be found, which depend upon thefe-pofitions, and which can be exhi¬ bited by equations: And, converfely, by the fame principles may the pofitions of figures be inferred from the equations denoting fuch relations of their parts. Though this application of algebra appears to be indireCt, yet fuch is the fimplicity of the operations, and the general nature of its theorems, that inveftiga- tions, efpeciaHy in the higher parts of geometry, are generally eafier' and more expeditious by the alge¬ braical method, though lefs elegant than by what is purely geometrical.. The connections alfo, and ana¬ logies of the two fciences eftablifhed by this appli¬ cation, have given rife to many curious fpeculations. Geometry has been rendered far more extenfive and ufeful, and algebra itfelf .has received confiderable im» provements. I. Of the Algebraical ExpreJJidn of Geometrical Mag" nitudes. A line, whether known or unknown, is reprefented by a fingle letter: a redangle is properly expreffed by the produCt of the two letters reprefenting its fides : and a redangular parallelepiped by the produCt of three letters ; two of which reprefent the fides of any of its rectangular bafes, and the third the altitude. Thefe are the moll fimple expreffions of geometrical magnitudes; and any other which has a known pro¬ portion to thefe, may in like manner be exprdfed al¬ gebraically. Converfely, the geometrical magnitude^ . reprefented by fuch algebraical quantities, may be found, only the algebraical dimenfions above the third, not having any correfponding geometrical dimenfions,. mult be expreffed'by proportionals (a). The .oppofite pofition of ftraight lines, it has been remarked, may be expreffed by the figns + and —. Thus, let a point A be given in the line f A~ M P~~ B AP, any fegment AP taken to the right hand being confidered as politive, a fegment Ap to the left is pro¬ perly (a) All algebraical dimenfions above the third mull he exprefled by inferior geometrical dimenfions; and though any algebraical quantities of two or three dimenfions may be immediately expreffed by furfaces and . fplids refpeCtively, yet it is generally neceffary to exprefs them, and all fuperior dimenfions,;, by lines., If, in any geometrical inveftigation by algebra, each line is expreffed by a fingle letter, and each furface or folid by an algebraical quantity of two or three dimenfions refpeCtively, then .whatever legitimate operations are „■ performed with regard to them, the terms in any equation derived will, when properly reduced, be all of. the fame dimenfion ; and any fuch equation may be eafily expreffed geometrically by means of proportionals, as in the following example. Thus, if the algebraical equation —ff4, is to be expreffed geometrically, a, b, c, and d, being fup- . pofed to reprefent ftraight lines ; \&. a \b \ e \f‘. g, in continued proportion, then aA :b* :: a-, g and a* -.a* b* :: a : a+g ; then-let a : c: h : k :l, and a4 : cA :: a: 1; alfo, \et c : d; m : n : p, and c4 : d4: : c: p, or c{ : c4 -—d\ :: c: c—p. By combining the two former proportions (Chap. II. Part I.), c4 ‘.a4 +b4 : : l: a-j-g, and combining the latter with this laft.found, c4~~d4 :; c—pXl; cXa+g; therefore c—pXl= cXa-j-g, and 9ie—p:ilia+g. If: Partlll. A L G Application perly reprefented by a negative quantity. If a and b to Geo- reprefent two lines; and if, upon the line AB from i, . e^‘ . the point A, AP be taken towards the right equal to a, it may be expreffed by -\-a; then PM taken to the left and equal to b, will be properly reprefented by —b, for AM is equal to a—b. If a—b, then M will fall upon A, and a—b—o. By the fame notation, if b is greater than a, M will fall to the left of A ; and in this cafe, if 2a—b, and if Pp be taken equal to b, then (a—b~) —a will reprefent Ap, which is equal to a, and fituated to the left of A. This ufe of the figns, however, in particular cafes, may be precluded, or in fome meafure reftrained. The pofitions of geometrical figures are fo various, that it is impoffible to give general rules for the alge¬ braical expreffion of them. The following are a few examples. An angle is exprefled by the ratio of its fine to the radius; a right angle in a triangle, by putting the fquares of the two fides equal to the fquare of the hy- pothenufe; the pofition of points is afcertained by the perpendiculars from them on lines given in pofition ; the pofition of lines by the angles which they make with given lines, or by the perpendiculars on them from given 'points ; the fimilarity of triangles by the proportionality of their fides which gives an equation, &c. Thefe and other geometrical principles mufl be em¬ ployed both in the demonftration of theorems and in the folution of problems. The geometrical propofition muft firft be expreffed in the algebraical manner, and the refult after the operation muft be expreffed geome- |i trically. II. The Demonjlration of Theorems. All propofitions in which the proportions of mag¬ nitudes only are employed, alfo all propofitions expref- fing the relations of the fegments of a ftraight line, of their fquares, rectangles, cubes, and parallelepipeds, are demonftrated algebraically with great eafe. Such 1 demonftrations, indeed, may in general be confidered as an abridged notation of what are purely geome¬ trical. This is particularly the cafe in thofe propofitions which may be geometrically deduced without any con- ftruftion of the fquares, reftangles, &c. to which they refer. From the firft propofition of the fecond book of Euclid, the nine following may be eafily derived in this manner, and they may be confidered as proper, ex¬ amples of this moft obvious application of algebra to geometry. If certain pofitions are either fuppofed or to be in¬ ferred in a theorem, we muft find, according to the preceding obfervations, the connexion between thefe pofitions and fuch relations of magnitude as can be ex¬ preffed and reafoned upon by algebra. The algebrai- E B R A. 435 cal demonftratioris of the 12th and 13th propofitions Application of the 2d book of Euclid, require only the 47th of the t0 Ge0' I. El. The 35th and 36th of the 3d book require only 1 nu^ry' , the 3. III. El. and 47. I. El. From a few fimple geometrical principles alone, a number of conclufions, with regard to figures, may be deduced by algebra; and to this in a great meafure is owing the extenfive ufe of this fcience in geometry. If other more remote geometrical principles are occa- fionally introduced, the algebraical calculations may be much abridged. The fame is to be obferved in the folution of problems ; but fuch in general are lefs ob¬ vious, and more properly belong to the ftrift geome¬ trical method. III. Of the Solution of Problems. Upon the fame principles are geometrical problems to be refolved. The problem is fuppofed to be con- ftrufled, and proper algebraical notations of the known and unknown magnitudes are to be fought for, by means of which their connexions may be expreffed by equations. It may firft be remarked, as was done in the cafe of theorems, that in thofe problems which re¬ late to the divifions of a line and the proportions of its parts, the expreffion of the quantities, and the ftating their relations by equations, are fo eafy as not to re¬ quire any particular direftions. But when various po¬ fitions of geometrical figures and their properties are introduced, the folution requires more attention and fidll. No general rules can be given on this fubjedt, but the following obfervations may be of ufe. 1. The conftruXion of the problem being fuppofed, it is often farther neceffary to produce fome of the lines till they meet; to draw new lines joining remark¬ able points; to draw lines from fuch points perpendi¬ cular or parallel to other lines, and fuch other opera¬ tions as feem conducive to the finding of equations ; and for this purpofe, thofe efpecially are to be employ¬ ed which divide the fcheme into triangles that are gi¬ ven, right angled or fimilar. 2. It is often convenient to denote by letters, not the quantities particularly fought, but fome others from which they can eafily be deduced. The fame may be obferved of given quantities. 3. The proper notation being made, the neceffary equations are to be derived by the ufe of the moft fim¬ ple geometrical principles; fuch as the addition and fub- ftraftion of lines or of fquares, the proportionality of lines, particularly of the fides of fimilar triangles, See. 4. There muft be as many independent equations as there are unknown quantities affumed in the inveftiga- fion, and from thefe a filial equation may be inferred by the rules of Part I. If the final equation from the problem be refolved, the roots may often be exhibited geometrically; but the geometrical conftruXion of problems may be ef- 3 I 2 feXed p If any known line is affumed as 1, as its powers do not appear, the terms of an equation, including any of them, may be of very different dimenfions ; and before it can be properly expreffed by geometrical magnitudes, the deficient dimenfions muft be fupplied by powers of the 1. When an equation has been derived from geo¬ metrical relations, the line denoting 1 is known ; and when an affumed equation is to be expreffed by the rela¬ tions of geometrical magnitudes, the 1 is to be'affumed. In this manner may any fingle power be expreffed by a line. If it is then to 1, x find four quantities in continued proportion; fo that 1 ; xy, then 1 ; y :; or ; and fo of others. 436 A L G E Application fefted alfo without refolvtng the equation, and even to G30. wJthout deducing a final equation, by the methods af- v me“y' , terwards to be explained. If the final equation is fimple or quadratic, the roots being obtained by the common rules, may be geome¬ trically exhibited by the finding of proportionals, and the addition or fubtradlion of fquares. By inferting numbers for the known quantities, a numeral expreffion of the quantities fought will be ob¬ tained byrefolving the equation. But in order to de¬ termine fome particulars of the problem befides finding the unknown quantities of the equation, it may be far¬ ther neceflary to make a fimple conftruftion ; or, if it is required that every thing be expreffed in numbers, to fubftitute a new -calculation in place of that con- itru&ion.

This is prop, nth II. B. of Eucl. C A C B Let C be the point of divifion, and let ABr=tr, — and then CB = tf—x. From the problem a1—a.Y = .va; and this equation being refolved (Chap. ¥. P.

But if a line AC be taken on the oppofite fide of A, and equal to the above-mentioned hypothenufe,together with —, it will reprefent the negative root—^'a 2 4 — —, and will give another folution ; for in this cafe alfo ABxBc= Ac\ But c is without the line AB ; and therefore, if it is not confidered as making a divi¬ fion of AB, this negative root is rejected. This folution coincides with what is given by Eu¬ clid, For yV-j-a2 is equal (fee the fig. of Prop, i ith II. B. Eucl. Simfon’s edit.) to EB or EF, and there¬ fore xz: « =EF—EA=AF=AH; and 4 2 the point H correfponds to C in the preceding figure. Befides, if on (EF+EA=) CF (inftead of EF— EArrFA) a fquare be defcribed on the oppofite fide of CF from AG, BA produced will meet a fide of it in a point; which if it be called K, will give.KBxBA r=KA2. K correfponds to c, and this folution will correfpond with the algebraical folution- by means of the negative root. If CB had been called x, and AC—«—x, the equa¬ tion would be axzza^-zax-t-x2, which gives x = 5a. , in which both roots are pofitive, and the BRA. Part IIL folutions derived from them coincide with the prece-Application ding.

Hence lines may be defined in various methods, of which the moll convenient is to be deter¬ mined by the purpofe in view. The fimplicity of a definition, and the eafe with which the other proper¬ ties can be derived from it, generally give a prefe¬ rence. being multiplied by 2, and added to the former, gives 2^x~a2—lax-f-x2, which being refolved accord¬ ing to the rules of Part I.

Either of the points, therefore, in which thefe two loci interfeft each other, as O, will give OP an ordinate in both equations, KP being the common abfcifs ; therefore KP, OP are the two perpendiculars required^ from which the point F is eaidy found. The conftruftion might have been made on figure ift, with fewer lines. If the circle touches LN, there is only one folutipn which is a minimum; and if the circle (does not meet LN? the problem becomes impoffible.

It may be remarked alfo, that the point which gives the fum of the fquares a minimum, is found by dividing the bafe, in the proportion of the fquares of the two fides of the triangle ; and this is eafily demondrated from the preceding condru&ion. Pros. V. Between two given Lines to find two mean Proportionals. Let the lines be a and b, and let the two means be x and y; therefore a : x :y : b, and hence ay=x*, and bx—y'1, which are both equations to the parabola, and are eafily condm&ed. The co-Ordinates at the inter* feftion of thefe two loci will be the means required. If one unknown quantity only is aflumed, or if it is convenient to deduce a final equation containing only one, the condrlufrion of the roots is to be obtained by the method mentioned in the next fe&ion. Scholium. The condruftions of the two preceding problems art geometrical; but it is fometimes convenient to have a practical folution, by the mechanical defcription either of the algebraical lines employed in the geometrical fo¬ lution, or of other geometrical lines by which it can be effe&ed. But few of thefe are tolerably accurate ; fo that, in general, by means of calculation, the prac¬ tical operations are all reduced to what may be per¬ formed by a ruler and a compafs. III. Ccnjlrufticn of Equations. The roots of an equation, containing only one un¬ known quantity, may be found by the interfedtion of lines, the produfr of whofe dimenfions is equal to the dimenfion of that equation. And hence problems are refolved without an algebraical folution of the equation arifing from them. Thus cubic and biquadratic equations may be con- firufted by the interfeftions of two conic feftions as the circle and parabola, which are generally affumed as freing moft eafily defcribed. In order to find thefe conftruftions, a new equation is to be affumed, containing two variable quantities, one of which is the unknown quantity of the given e- quation, and the other by fubllitution is to be inferted alfo in the given equation ; the interfeftion of the loci of thefe equations will exhibit the roots required. Canons may be devifed for the conftruftion of par¬ ticular orders, without affuming the new equation. The final equation from prob. 5. would be x5 ~a'lb, which being conftrufted according to the rules, exhi¬ bits the common geometrical folution of that problem by the circle and parabola. If an equation be affumed, as ayenx1, the other by fubftitution becomes xyz=ab; the locus of the former is a parabola, and of the latter an hyperbola, one of its affymptotes being the bafe, and the co-ordinates at their interfeftion will reprefent x ancTy; the firftof the two means is x, and in this cafe y is the other. 3 K Equa- 442 A L G E Application Equations alfo might be affumed fo as to give a fo- to Geo- iU|-;on 0f problem by other combinations of two of < 1 >’y' the conic fe&ions, one of them not being the circle. As geometrical magnitudes may be reprefented by algebra, fo algebraical quantities and numbers may be reprefented by lines. Hence this conllruftion of equa¬ tions has fometimes been ufed as an eafy method of. approximation to the roots of numeral equations. For this purpofe, the neceffary ftraight lines muft be laid down by means of a fcale of equal parts, and the curve lines, on whofe interfefiion the conftru6ti6n depends, muft be aftually defcribed; the linear roots being mea- fiired on the fcale will give the numbers required. Thefe operations may be performed with fufficient ac¬ curacy for certain purpofes ; but as they depend on mechanical principles, the approximation obtained by them cannot be continued at pleafure; and hence it is BRA.

If the relation between the ordinate and abfeifs be fixed, but not expreftible by a finite equation, the curve is called Mechanical (a) or Tranfcehdental. This clafs is alfo fometimes defined by equations, by fuppofing 'either x or_)> in a finite equation to be a curve line, of which the relation to a ftraight line cannot be expref- fed in finite terms. If the variable quantities x or y enter the exponents of any term of an equation, the locus of that equation is called an Exponential Curve. Many properties of thefe two claffes of curves may be difcovered from their equations. A L G Al-redo AI.GEDO, the running of a gonorrhoea flopping 11 fuddenly after it appears.

The foil, however, is exceffively various; fome places being very hot, dry, and barren, on which account they are generally fiif- fered to lie uncultivated by the inhabitants, who are very negligent. Thefe barren places, efpecially fuch as lie on the fouthern fide, and are at a great diftance from the fea, harbour vaft numbers of wild creatures, as lions, tigers, buffaloes, wild boars, flags, porcupines,, monkeys, oftriches, &c.

A L G [ 443 ] A L G fien fubdu the Arab princes. Algiers, happened about the middle of the feventh century; 1 and the Arabs continued mailers of the country, di¬ vided into a great number of petty kingdoms or dates, a under chiefs of their own choofing, till the year 1051. Abu-Texe- This year, one Abubeker-ben-Omar, Or, as the Spa- csni{h authors call him, Abu-Texefien, an Arab of the Zinhagian tribe, being provoked at the tyranny of thofe defpots, gathered, by the help of his marabouts or faints, a moil powerful army of malcontents, in the fouthern provinces of Numidia and Libya. His fol¬ lowers were nicknamed Marabites or Morabites; by the Spaniards, Almoravides; probably from their being affembled principally by the faints who were alfo called Morabites. The khalif of Kayem’s forces were at this time taken up with quelling other revolts in Syria, Mefopotamia, &c. and the Arabs in Spain engaged in the moil bloody wars ; fo that Texefien having nothing to fear from them, had all the fuccefs he could wiih againit the Arabian cheyks or petty tyrants, whom he defeated in many battles, and at lail drove them not only out of Numidia and Libya, but out of all the weftern parts, reducing the whole province of Tingi- tania under his dominion. Texefien was fucceeded by his fon Yufef, or.Jofeph, a brave and warlike prince. In the beginning of his reign, he laid the foundation of the city of Morocco, which he defigned to make the capital of his empire. While that city was building, he fent fome of his ma¬ rabouts ambafiadors to Tremecen (now a province of Algiers), at that time inhabited by a powerful and infolent fe£t of Mahometans called Zeneti. The de- fign of this embaffy was to bring them back to what he called the true faith ; but the Zeneti, defpifing his of¬ fers, affembled at Amaf, or Amfa, their capital, mur¬ dered the ambaffadors, and invaded Jofeph’s dominions with an army of 50,000 men. The king hearing of their infamous proceedings, firoyed. fpeedily muftered his army, and led it by long marches into their country, dellroying all with fire and fword ; - while the Zeneti, inftead of oppofing his progrefs, re¬ tired as fall as poffible towards Fez, in hopes of recei¬ ving affiftance from-thence. In this they were miferably deceived : the Fezzans marched out againll them in a hollile manner; and coming up with the unhappy Ze¬ neti, encumbered with their families and baggage, and ready to expire with hunger and wearinefs, they cut them all to pieces, except a fmall number who were mollly drowned in attempting to fwim acrofs a river, and feme others who ‘ in their flight perilhed by falling from the high adjacent rocks. In the mean time ■ Jofeph reduced their country to a mere defart: which was, however, foon peopled by a numerous colony of Fezzans, who fettled there under the proteftion of the reigning kings. In this war ft is computed that near a million of the Zeneti, men, women, and children, loll their lives. The reftlefs and ambitious temper of Jofeph did not let him remain long at peace, fie quickly declared war again!! the Fezzans, reduced them to become his tributaries, and extended his conquefts all along the Mediterranean. He next attacked fome Arabian cheyks who had not yet fubmitted to his jurifdiftion; and pur- fued them with fuch fury, that neither the Libyan de¬ farts, nor ridges of the molt craggy rocks, could {bel¬ ter them from his arms. He attacked them in fuch of their retreats, caftles, and fortreffes, as were till then deemed impregnable ; and at laft fubdued them, to the great grief of the other African nations, who were great¬ ly annoyed by the ravages committed by his; numerous forces. Algiers. Thus was founded the empire of theMorabites; which, however, was of n6 long duration ; that race being in the j 2th century driven out by Mohavedin, a marabout. This race of priefts was expelled by Abdnlac governor of Fez; and he, in the 13th century, ftripped of his new 4 conquefts by the Sliarifs of Hafcsn, the defeendants of sharifs of thofe Arabian princes whom Abu-Texefien had for- Hafcen merly expelled. w*10* The better to fecure their new dominions, the Sha¬ rifs divided them into feveral little kingdoms or pro¬ vinces ; and among the reft the prefent kingdom of Algiers was divided into four, namely, Tremecen. Te- nez, Algiers propert and Bujeyah. The four firft mo- narchs laid fo good a foundation for a lafting balance of power between their little kingdoms, that they con¬ tinued for fome centuries in mutual peace and amity ; but at length the king of Tremecen having ventured to violate fome of their articles, Abul-Farez, king of Tenez, declared war againft him, and obliged him to become his tributary. This king dying foon after, and having divided his kingdom among his three fons, new difeords arofe ; which Spain taking advantage of, a powerful fleet and army was fent againft Barbary, un- ^ der the Count of Navarre, in 1505. This commander Algerinesin foon made himfelf mafter of the important cities of dangerfroni Oran, Bujeyah, and fome others ; which fo alarmed ^ Spani- the Algerines, that they put themfelves under the pro-ar s" teftion of Selim Eutemi, a noble and warlike Arabian prince. He came to their afliftance with a great num¬ ber of his brave!! fubje&s, bringing with him his wife Zaphira, and a fon then about 12 years old. This however was not fufficient to prevent the Spaniards from landing a number of forces near Algiers that fame year, and obliging that metropolis to become tributary to Spain. Nor could Prince Selim hinder them from building a ftrong fort on a fmall Hand oppofite to the city, which terrified their corfairs from failing either in or out of the harbour. To this galling yoke the Algerines were obliged to fubmit till the year 1516 ; when, hearing of the death of Ferdinand king of Spain, they fent an embaffy to 6 Aruch Barbaroffa, who was at this time no lefs dread- inv;re 3^ ed for his valour than his furprifing fuccefs, and was barofla. then fent on a cruize with a fquadron of galleys and barks. The purport of the embaffy was, that he fliould come and free them from the Spanifh yoke ; for which they agreed to pay him a gratuity aufwerable to fo great a fervice. Upon this Barbaroffa immediately difpatched 18 galleys and 30 barks to the affiftance of the Algerines ; while he himfelf advanced towards the city with 800 Turks, 3000 Jigelites, and 2000 Moorifti volunteers. Inftead of taking the neareft road to Al¬ giers, he directed his courfe towards Sharjhel, where Hajfan, another famed corfair, had fettled himfelf. Him he furprifed, and obliged to furrender; not without a previous promife of friendfliip : but no fooner had Bar¬ baroffa got him ip his power, than he cut off his head; and obliged all Haffan’s Turks to follow him in his new expedition. On Barbaroffa’s approach to Algiers, he was met by 3 K 2 prince A L G [ 444 3 A L G Algiers, prince Eutemi, attended by all the people of that me- capital, which he eafily made himfeff mailer of; and, Algiers, ' tropolis, great and fmall; who looked for deliverance having given it up to be plundered by his Turks, obli- His treach- from this abandoned villain, whom they accounted in- ged the inhabitants to acknowledge him as their fove- eiy and vincible.

The king of Tremecen,. not fufpedling the treachery of his fubjedls, met the tyrant with an army of 6000 horfe and 3000 foot: but Barbarofla’a. artillery gave him fuch an advantage, that the king was at length forced to retire into the capital; which he had no fooner entered, than his head was cut off, and fent to Barbarofla, with a frelh invitation to come and take pofleffion of the kingdom; On his approach, he brutality of this new king, whom fhe unfuccefsfully en- was met by the inhabitants, whom he received with great deavoured to flab with a dagge: Barbarofla was no fooner feated on the throne, than he treated his fubjedls with fuch cruelty, that they ufed to fhut up their houfes and hide themfelves when he ap¬ peared in public. In confequence of this, a plot was complaifance, and many fair promifes ; but beginning to tyrannize as ufual, his new fubjedls foon convinced him that they were not fo paffive as the inhabitants of Algiers. Apprehending, therefore, that his reign might prove uneafy and precarious, he entered into an foon formed againft him; but being difeovered, he cau- alliance with the king of Fez ; after which, he took fed twenty of the principal cqnfpirators to be behead¬ ed, their bodies to be buried in a dunghill, and laid a heavy fine on thofe who furvived.

But the fleet was no fooner come within fight of land,, than Men: but their cabals being difeovefed,. a great n ber of the confpirators were maflacred in the mo ft cruel - manner. The prince had the good luck to efcape to Oran, and was taken-under the protedlion of the mar¬ quis of Gomarez, who fent immediate advice of it to Charles V. then lately arrived in Spain, with a power¬ ful fleet and army.

Moll of the Spa¬ niards were drowned ; and the few who efcaped to fliore were either killed by the Turks or made flaves. Though BarbaroiTa had nothing to boaft on this oc- cafion, his pride and infoknee were now fwelled to fuch a degree, that he imagined himfelf invincible, and that the very elements confpired to make him fo. The A- rabians were fo much alarmed at his fuccefs, that they implored the afliftance of Hamidel Abdes king of Te¬ nez, to drive the Turks out of Algiers. That prince readily undertook to do what was in his power for this purpofe, provided they agreed to fettle the kingdom on himfelf and his defeendants. This propofal being accepted, he immediately fetout at the head of 10,coo command of the governor of Oran ; who, under the guidance of Abuchen Men, began his march towards Tremecen ; and in their way they were joined by prince Selim, with a great number of Arabs and Moors. The firft thing they refolved upon was, to attack the im¬ portant fortrefs of Calau, fituated between Tremecen and Algiers, and commanded by the corfair Efcander at the head of about 3,00 Turks. They in veiled it clofely on all fides, in hopes Barbarofla would come out of Tremecen to its relief, which would give the Tre- mecenians an opportunity of keeping him out. That tyrant, however, kept clofe in his capital, being em- barafied by bis fears of a revolt, and the politic delays of the king of Fez, who had not fent the auxiliaries Moors; and, upon his entering the Algerine domini- he promifed.

Barbaroffa being now informed that Abuchen Men, with his Arabs, accompanied by the Spaniards, were in full march to lay fiege to Tremeccn, thought pro¬ per to come out, at the head of 1500 Turks and 5000 Moorifh horfe, in order to break his way through the enemy ; but he had not proceeded far from the city, before his council advifed him to return and fortify himfelf in it. This advice was now too late ; the in¬ habitants being refolved to keep him out, and open their gates to their own lawful prince as foon as he appear¬ ed. In this diftrefs Barbaroffa faw no way left but to retire to the citadel, and there defend himfelf till he could find an opportunity of Healing out with his men and all his treafure. Here he defended himfelf vigo- roufly ; but his provifions failing him, he took advan¬ tage of a fubterraneous back-way, which he had caufed to be digged up for that purpofe, and, taking his im- menfe treafurewith him,Hole awayasfecretlyashe could. His flight, however, was foon difeovered ; and he was fo clofely purfued, that to amufe, as he hoped, the ene¬ my, he caufed a great deal of his money, plate, jewels, &c. to be fcattered all the way, thinking they would not fail to Hop their purfuit to gather it up. This ftratagem, however, failed, through the vigilance of the Spanifh commander, who being himfelf at the head of the purfuers, obliged them to march on, till he was come up clofe to him on the banks of the Huexda, a- bout eight leagues from Tremecin. Barbaroffa had juft croffed the river with his vanguard, when the Spa¬ niards came up with his rear on the other fide, and cut them all off; and then croffing the water, overtook him at a fmall diftance from it. Here a bloody engagement enfued, in which the Turks fought like as many lions; but, being at length overpowered by numbers, they were all cut to pieces, and Barbaroffa among the reft,, in the 44th year of his age, and four years after he had raifed himfelf to the royal title of Jigel and the adja¬ cent country ; two years after he had acquired the fo- vereignty of Algiers, and fcarce a- twelvemonth after the reduction of Tremecen. His head was c. rried to Tremecen, on the point of a fpear; and Abuchen Men proclaimed king, to the joy of all the inhabitants. A few days after the fight, the king of Fez made his ap¬ pearance at the Itead of 20,000 horfe, near the field of battle; but hearing of Barharoffa’s defeat and death, marched off with all poffible fpeed, to avoid being attacked by the enemy. The news of Barbaroffa’s death fpread the utmoft conflernation among the Turks at Algiers ; however, they caufed his brother Hayradin to be immediately proclaimed king. The Spanifh commander now fent back the emperor’s-forces, without making any at¬ tempt upon Algiers ;.by which he loft the opportunity of driving the Turks out of that country ; while Hay¬ radin, juftly dreading the confequences of the tyranny of his officers, fougbt the protedlion of the Grand Sig- nior.

In this he employed 30,000 Chriftian flaves, whom he obliged to work without in- termiffion for three years; in which time the work was completed. He then caufed the fort he had taken from the Spaniards to be repaired, and placed a ftrong garrifon in it, to prevent any foreign veffels from en¬ tering the harbour without giving an account of them- felves. By thefe two important works, Hayradin foon became dreaded not only by the Arabs and Moors, but alfo by the maritime Chriftian powers, efpecially the Spaniards. The viceroy failed not to acquaint the Grand Signior with his fuccefs, and obtained from him-, a frefh fupply of money, by which he was enabled to build a ftronger fort, and to ere ft batteries on all places • that might favour the landing of an enemy. All thefe have fince received greater improvements from time to time, as often as there was occafion for them. In the mean time the Sultan, either out of a fenfe of the great fervices Hayradin had done, or perhaps out of jealoufy left he ftiould make himfelf independent, raifed Hayradin to the dignity of baftiaw of the em- rI pire, and appointed Haffan Aga, a Sardinian renega-Succeeded; do, an intrepid warrior, and an experienced officer, V Haffan to fucceed him as bafhaw of Algiers, Haffan had no Asa' fooner taken poffeffion of his -new government, than he began to purfue his ravages on the Spanifh coaft with greater fury than ever; extending them to the ecclefi- aftical ftate, and other parts of Italy. But Pope Paul III. being alarmed at this, exhorted the emperor Charles V. to fend a powerful fleet to fupprefs thofe frequent and cruel piracies;, and, that nothing might be wanting to render the enterprife fuccefsful, a bull was publifhed by his holinefs, wherein a plenary abfo- lution of fins, and the crown of martyrdom, was pro- mifed to all thofe whq either fell in battle or were made flaves; the emperor on his part, needed no fpur 5 Charles and therefore fet fail at the head of a powerful fleet Vth’s expe- eonfifting of 120 ftiipa and 20 gallies, having on board dition a- 30,000 chofen troops, an immenfe quantity of money, Al¬ arms, ammunition, &c.

But to this Halfan only replied, that he muft be a madman who would pretend to advife an enemy, and that the advifed muft ftill aft more madly who would take counfel of fuch an advifer. He was, however, on the point of furrender¬ ing the city, when advice was brought him that the forces belonging to the weftfern government were in a poor fortune-teller, which had been obtained by the fervent prayers of an eminent faint of their own profef- fion. But though the balhaw and his douwan feemed, out of policy, to give into this laft notion, yet the im- preffion which YufePs prediftions and their late accom- plifhments had made upon the minds of the common people, proved too ftrong to be eradicated; and the fpi- rit of divination and conjuring has fince got into fuch full march towards the place; upon which it was refol- credit among them, that not only their great ftatefmen. ■ed to defend it to the utmoft.

This difafter was owing to the inconfi- derate raftmefs, or rather madnefs, of the commander ; which was fo great, that, after finding it impofiible to rally his fcattered forces, he rufhed, fword in hand, into the thickeft of the enemy’s ranks, at the head of a fmall the Porte.

Mahomet, being foon after recalled, was fucceed- ed by the famous renegade Ochali, who reduced the 'kingdom of Tunis; which, however, remained fub- jeft to the viceroy of Algiers only till the year 1586, when a bafhaw of Tunis was appointed by the Porte. The kingdom of Algiers continued to be governed, till the beginning of the feventeenth century, by vice¬ roys or bafhaws appointed by the Porte ; concerning whom we find nothing very remarkable, further than that their avarice and tyranny was intolerable both to obfervation of which they obliged all their fubjefts to fwear ; and the militia, navy, commerce, &c. were all fettled pretty nearlyon the footing upon which they now are, and which fhall be afterwards deferibed ; tho’ the fubfequent altercations that frequently happened be¬ tween the bafhaws and deys, the one endeavouring to recover their former power, and the other to curtail it, caufed fuch frequent complaints and difeontents at the Ottoman court, as made them frequently repent their compliance. In the year 1601, the Spaniards, under the com¬ mand of Doria the Genoefe admiral, made another at¬ tempt upon Algiers, in which they were more fortu¬ nate than ufual, their fleet being only driven back by contrary winds, fo that they came off without lofs.

The next year, the Coulolies, or Celoglies (the chil¬ dren of fuch Turks as had been permitted to marry at Algiers), who were enrolled in the militia, having fei- zed on the citadel, had well nigh made themfelves mailers of the city; but were attacked by the Turks and renegadoes, who defeated them with terrible flaughter. Many fcores of them were executed ; and their heads thrown in heaps upon the city-walls, without the eaftern gate. Part of the citadel was blown up; and the remaining Coulolies were difmilTed from the militia, to which they were not again admitted till long after. In 1623, the Algerines and other Hates of Barbary *»ruai 1 threw off their dependence on the Porte altogether, and throw off fet Up for themfelves.

Thefe two large vef- fels having got the fmall frigate between them, plied her furioufly with great Ihot, which foon took off her main mall: notwithftanding which, the French made fo defperate a refiftance, that the pirates were not able to take them, till the noife of their fire brought up five more Algerines ; when the French veffel, being almoll torn to pieces, was boarded and taken.

But though Pinchinin thus returned in difgrace, the reft of the fleet quickly, came back with vaft numbers, of (laves, and an immenfe quantity of rich fpoils ; info- much that the Englifti, French, and Dutch, were o- bliged to cringe to the mighty Algerines, who fome- times vouchfafed to be at peace with them, but fwore eternal war againft Spain, Portugal, and Italy, whom they looked upon as the greateft enemies to the Maho- metan name.

AH the regulations of ftate ought to be determined by that affembly, before they pafs into a law, or the dey hath power to put them in execution: but, for many years back, the douwan is of fo little account, that it is only convened out of formality, and to give aflent to what the dey and his chief favourites have concerted Strangeme- beforehand. The method of gathering the votes in this thod ofga- auguft affembly is perfectly agreeable to the charafter votesefr the t^°^e w^° compofe it.

From- the loudnefs of this growling noife, the aga is left to guefs as. well as he can whether the majority of the af¬ fembly are pleafed or difpleafed with the queftion; and from luch a prepofterous method, it is not furprifing that thefe affemblies fhoivld feldom end without fome tumult or diforder. As the whole body of the militia- is concerned in the election of a new dey, it is feldom carried on without blows and bloodftied: but-when once the choice is made, the perfon elected is fainted with the words Alla Barick, “ God blefs you, and profper you and the new dey ufually caufes all the officers of the douwan who had oppofed his eledtion to be ftrangled, filling up their places with thofe who had been moft zealous in promoting it. From this ac¬ count, of the eledtion of the deys, it cannot be expec¬ ted that their government fhould be at all fecure ; and as they arrive at the throne by tumult, diforder, and bloodffied, they are generally deprived of it by the fame means, fcarcely one in ten of them having the good fortune to die a natural death. In this country it is not to be expe&ed that jtiftice will be adminiftered with any degree of impartiality. Punifh- The Mahometan foldiery, in particular, are fo much mems, &c. favoured, that they are feldom put to death for any crime, except rebellion ; in which cafe they are either ftrangled with a bow-ftring, or hanged to an iron hook. In leifer offences, they are fined, or their pay flopped; and if officers, they are reduced to the ftation of com¬ mon foldiers, from whence they may gradually raife themfelves to their former dignity. Women guilty of adultery, have a halter tied about their necks, with the other end faftened to a pole, by which they are held under water till they are fuffocated. The baftinado is likewife inflidled for fmall offences; and is given either upon the belly, back, or foies of the feet, according to the pleafure of the cadi; who alfo appoints the num¬ ber of ftrokes. Thefe fometimes amount to 200 or 300, according to the indulgence the offender can obtain either by bribery or friends ; and hence he often dies under this punifhment, for want of powerful enough advocates. But the moft terrible punifhments are thefe inflitfted upon the Jews or Chriftians who fpeak againft Mahomet or his religion; in which cafe, they muft ei¬ ther turn Mahometan, or be impaled alive. If they afterwards apoftatize, they are burned or roafted alive, Algiers, or elfe thrown down from the top of the city-walls, u,_nr*“ upon iron hooks, where they are caught by different parts of their body, according as they happen to fall, and fometiraesexpire in the greateft torments; though by accident they may be put out of pain at once, as we have already related of the Spanifh adventurer John Gafcon. This terrible puniftiraent, however, begins now to be be difufed. The officer next in power to the dey is the aga ofAgaof the the janizaries, who is one of the oldeft officers in the janizaries army, and holds his poll only for two months. He is “y then fucceeded by the chiah, or next fenior officer.;-— foe's. During the two monthsdn which the aga enjoys his dig¬ nity, the keys of the metropolis are in his hands ; all military orders are iflued out in his name ; and the fen- tence -of the dey upon any offending foldier, whether capital or not, can only be executed in the court of his palace.—As foon as he is gone through, this Ihorfc office, he is confidered as mazoul, or fuperannuated ; receives his pay regularly, like the reft of the militia, every two moons; is exempt from all further duties, ex¬ cept when called by the dey to affift at the grand coun¬ cil, to which he hath, however, a right to come at all times, but hath no longer a vote in it.—Next to the aga in dignity, is the fecretary of ftate, who regifters all the public adls; and after him are the 30 chiahs, or colonels, who fit next to the aga in the douwan, and in the fame gallery with him. Out of this clafs are generally chofen thofe who go embaffadors to fo¬ reign courts, or who difperfe the dey’s orders through¬ out the realm.— Next to them are 800 bolluck-bafhaws, or eldeft captains, who are promoted to that of chiah- baftpws, according to their feniority. The oldack- baftiaws, or lieutenantr, are next; who amount to 400; and are regularly, railed to the rank of captains in their turn, and to other employments in the ftate, according to their abilities. Thefe, by way of diftindlion, wear a leather ftrap, hanging down to the middle of their back. One rule is ftridlly obferved in the rotation of thefe troops from one deputy to a higher; viz. the right: of feniority ; one fingle infringement of which would eaufe an infurre&ion, and probably coft the dey his life. Other military officers of note are the vekelards, or purveyors of the army ; the peys, who are the four oldeft foldiers, and confequently the neareft to prefer¬ ment ; the foulacks, who are the next in feniority to them, and are part of the dey’s body-guard, always marching before him when he takes the field, and dif- tinguifhed by their carbines and gilt fcymiters, with a brafs gun on their caps; the kayts, or Turkifh fol¬ diers, each band of whom have the government of one or more adowars, or itinerant villages, and colledl their taxes for the dey ; and the fagiards, or Turkifh lance- men, 100 of whom always.attend the army, and watch over the water appointed for it. To thefe we may add the beys, or governors of the three great provinces of the realm. All the above-mentioned officers ought to coropofe the great douwan or council above-mentioned; but only the 30 chiah-bafhaws have a right to fit in the gallery next after the dey: The reft are obliged to ftand on the floor of the hall, or council-chamber, with their arms acrofs, and, as much as poffible, with¬ out motion ; neither are they permitted to enter with their fwords on, for fear of a tumult. As for thofe A L G [ 453 J A L G Civilian of the king¬ dom. who have any matters to tranfaft with the douwan, they muft ftand without, let the weather be ever fo bad ; and there they are commonly prefented with cof¬ fee by fome of the inferior officers, till they are dif- miffed. The kingdom of Algiers is at prefent divided into three provinces or diftri&s, viz. the eaflern, weftern. (8.) The Ladag, or Ludeg, runs down from mount | Algierv^ Atlas through part of Conftantina, and falls into the fea a little eaftward of Bona. (9.) Guadi, or Guadel Barbar, fprings from the head of Orbus, or Urbs, in Tripoli, runs through Bujeyah, and falls into the fea near Tabarea. 58 Befides thefe there are many others of lefs note; of Account of and fouthern. The eallern, or Levantine government, which, however, we do not find that the Algerines which is by far the moil confiderable of the three, and is vail themfelvea as they might do, their genius leading &c, 5 -ir u^j rn— n—n— them too much to the piratical trade to mind any real 56 Rivers. alfo called Bey lick, contains the towns of Bona, Conflan- tina, Gigeri, Bujeyah, StefTa, Tebef, Zamoura, Bifcara, and Necanz, in all which the Turks have their garri- fons : befides which, it includes the two ancient king¬ doms of Cuco and Labez, though independent of the Algerine government, to whofe forces their country is inacceffible; fo that they ftilllive under their own cheyks chofen by each of their adowars or hords. To thefe we may add a French factory at Callo, under the di- reCtion of the company of the French Ballion.—The weftern government hath-the towns of Oran, Tremecen, Moftagan, Tenez, and Seerelly with its caftle and gar- rifon.—The fouthern government hath neither town, village, nor even a houfe, all the inhabitants living in tents, which obliges the dey and his forces to be al¬ ways encamped. The moft confiderable rivers of Algiers are the Zha, or Ziz, which runs acrofs the province of Tremecen, and the defert of Anguid, falling into the Mediterra- ir the town of Tabecrita, where it has the name advantage that might be derived from their own coun¬ try. The corfairs, or pirates, form each a fmall re¬ public, of which the rais or captain is the fupreme bafhaw; who, with the officers under him, form a kind of douwan, in which every matter relating to the vef- fel is decided in an arbitrary way. Thefe corfairs are chiefly mftrumental in importing whatever commodities are brought into the kingdom either by way of mer- chandife or prizes. Thefe confift chiefly of gold and fdver fluffs, damafks, cloths, fpices, tin, iron, plated brafs, lead, quiekfilver, cordage, fail-cloth, bullets, cochineal, linen,, tartar, alumj. rice, fugar, foap, cot¬ ton raw and fpun, copperas, aloes, brazil and log¬ wood, vermilion,. &c. Very few commodities, however,, are exported from this part of the world: the oil, wax, hides, pulfe, and corn produced, being but barely fuffi- cient to fupply the country; though, before the lofs of. Oran, the merchants have been known to fhip off from- one or other of the ports of Barbary feveral thoufand. of Strut. (2.) The Haregol, fuppofed the Sign of Pto- tons of com. The confumption of oil, though here in- lemy, comes down from the great Atlas, croffes the defert of Anguid, and falls into the fea, about five great abundance, is likewife fo confiderable in this king- dbm, that it is feldom permitted to be fnipped off. for leagues from Oran. (3.) The Mina, fuppofed the Cky* Europe. The other exports confift chiefly in oftriches leviatis of Ptolemy, a large river, which runs through the plains of Bathala, and falls into the fea near the town of Arzew. This river hath lately received the name of Cena, who rebuilt the town of Bathalah af¬ ter it had been deftroyed. (4.) The Shellif, Zilef, or Zilif, defeending from the mount Gnanexeris, runs through fome great deferts,.the lake Titteri, the fron¬ tiers of Tremecen and Tenez, falling into the iea a little above the city of Moftagan. (5.) The Celef, feathers, copper, ruggs, filk fafhes, embroidered hand¬ kerchiefs, dates, and Chriftian flaves. Some manu- fatflures in filk, cotton, wool, leather, &c. are car¬ ried on in this country, but moftly by the Spaniards fettled here, efpecially about the metropolis. Carpets are alfo a manufacture of the country, which, though much inferior to thofe of Turkey, both in beauty and finenefs, are preferred by the people to lie upon, on account of their being both cheaper and fofter. There fuppofed to be the Cartkena of the ancients, falls into are alfo, at Algiers, looms for velvet, taffaties, and other the fea about three leagues weft of Algiers, after a fhort courfe of 18 or 20 leagues. (6.) The Hued-al- quivir, fuppofed to be the Nalabata, or Nafaba, of the ancients, and called by the Europeans Zinganir, runs down with a fwift courfe, through fome high moun- 57 tains of Cuco, and falls into the fea near Bujeyah. Harbour of Whilft the city of Bujeyah was in the hands of the Bujeyah Chriftians, the mouth of this river was fo choaked up accident ^ ^and> that no veffel could come up into it: but in r555» very foon after it: was taken by the Moors, the great rains fwelled it to fuch a degree, that all the fand and mud was carried off; fo that galleys, and other veffels, have ever fince entered it with eafe, where .they lie fafe from ftorms, and all winds, but that which blows from the north. ( 7.) Suf-Gemar, or Suf-Gimmar al Rumniel, fuppofed to be the Ampfaga of Ptolemy, hath its fource on mount Auras, on the confines of Atlas; thence runs through fome barren plains, and the fruit¬ ful ones of Conftantina, where its ftream is greatly ' ihcreafed by fome other rivers it receives ; from thence running northward, along the ridges of fome high mountains, it. falls into the fea a little eaft of Gigeri. & wrought filks; and a coarfe fort of linen is likewife made in moft parts of the kingdom. The country furnifhes- no materials for ftiip-building. They have neither ropes, tar, fails,, anchors, nor even iron. When they can procure enough of new wood to form the main timbers of a fhip, they fupply the reft from the materials of prizes which they have made; and thus find the fecret of producing new and fwift failing vef¬ fels from the ruins of the old. Of all the ftates on the coaft of Barbary, the Algerines are the ftrongeft at fea. The. inhabitants along the fea-coafts are a mixture Inhabitants, of different nations; but chiefly Moors and Morefcos driven out of Catalonia, Arragon, and other parts of Spain. Here are alfo great numbers of Turks, who come from the Levant to feek their fortune; as well as multitudes of Jews and Chriftians taken at fea-, who are brought hither to be fold for flaves. The Bere- bers are fome of the moft ancient inhabitants of the country; and are 'fuppofed to be defeended from the ancient Sabeans, who came hither from Arabia Felix,, under the condudt- of one of their princes. Others be. Ee.ve A L G [ 454 ] A L G lieve them to be fome of the Canaanites driven out of Paleftine by Jofhua. Thefe are difperfed all over Bar¬ bary, and divided into a multitude of tribes under their refpeftive chiefs: moft of them inhabit the mountainous parts; fome range from place to place, and live in tents, or portable huts; others in fcattered villages: they have, neverthelefs, kept themfelves for the moft part from in¬ termixing with other nations. The Berebers are reckon¬ ed the richeft of all, go better cloathed, and carry on a much larger traffic of cattle, hides, wax, honey, iron, and other commodities. They have alfo fome artifi¬ cers in iron, and fome manufa&urers in the weaving branch.—The name of Bereber is fuppofed to have been originally given them onraccount of their being firft fettled in fome defert place. Upon their increafing in procefs of time, they divided themfelves into five tribes, probably on account of religious differences, called the Zinhagians, Mufamedins, Zeneti, Hottres, and Gonn- res; and thefe having produced 600 families, fubdi- vided themfe'lves into a great number of petty tribes.— To thefe we may add the Zn.vo'wahs, by European au¬ thors called Azuagws, or Ajfagues, who are likewife difperfed over moft parts of Barbary and Numidia. Great numbers of thefe inhabit the mountainous parts of Cuco, Labez, &c. leading a wandering paftoral life.—But the moft numerous inhabitants are the Moors and Arabians- The former are very ftout and warlike, and fkilfiil horfemen ; but fo addicted to robbing, that one cannot fafely travel along the country at a diftance from the towns without a guard, or at leaft a marabout or faint for a fafeguard. Tor as they look upon them¬ felves to be the original proprietors of the country, and not only as difpoffeffed by the reft of the inhabitants, but reduced by them to the loweft ftate of poverty, they make no fcruple to plunder all they meet by way of reprifal. The inhabitants, in general, have a pretty fair complexion; they are robuft and well proportioned. People of diftinftion wear their beard ; they have rich clothes made of filk, embroidered with flowers of gold, and turbans enriched with jewels. The Turks, who cOmpofe the military force, have great privileges, pay no taxes, are never publicly punifhed, and rarely in private. The loweft foldier domineers over the moft diftinguilhed Moors at pleafure. If he finds them bet¬ ter mounted than himfelf, he exchanges horfes without ceremony. The Turks alone have the privilege of •carrying fire-arms. Many good qualities, however, diftinguifh them in fpite of this excefs of defpotifm. They never game for money, not even for trifles; and they never profane the name of the Deity. They foon forget their private quarrels; and after the firft pa- Toxyfim of refentment is over, it is infamy for a Turk to keep in remembrance the injuries he has received. In this refpect certainly they are lefs barbarous than ■other nations that boaft of their civilization. See Moors. Algiers, a city, the capital of the above king¬ dom, is probably the ancient Icojium: by the Arabians called Algezair, or rather Al-Jezicr^ or Al-Jezerah, i. e. the ijland, becaufe there was an ifland before the city, to which it hath'been finee joined by a mole. It is built on the declivity of a hill by the fea-fide, in the form of an amphitheatre: at fea, it looks like the top- fail of a Ihip. The tops of the houfes are quite flat and white ; infomuch, that when it is firft difcovered, one 3 would take it to be a place where they bleach linen. Algiers. One houfe rifes above another in fuch a manner that—v— they do not hinder each other’s profpeft. The ttreets are fo narrow, that they will fcarce admit two perfons to walk a-breaft, and the middle part is lower than the Tides. When any loaded beafts, fuch as camels, horfes, mules, or affes, pafs along, you are forced to ftand up clofe to the wall to let them pafs by. There is but one broad ftreet, which runs through the city ftops eaft to weft, in which are the (hops of the prin¬ cipal merchants, and the market for corn and other com¬ modities. The lower part of the walls of the city are of hewn ftone, and the upper part of brick ; they are 30 feet high on the land fide, and 40 towards the fea; the foffes or ditches are twenty feet broad, and feven deep. There is no fweet water in the city ; and tho* there is a tank or ciftern in every houfe, yet they often want water, becaufe it rains but feldom: the chief fup- ply is from a fpring on a hill, the water of which is conveyed by pipes to above a hundred fountains, at which a bowl is faftened for the ufe of paffengers. The common refervoir is at the end of the mole, where the fhips take in their water. Every one takes his turn at thefe places, except the Turks, who are firft, and the Jews laft. There are five gates, which are open from fun- rifing till fun-fetting ; and feven forts, or caftles, with¬ out the walls, the greateft of which is on the mole with¬ out the gate, all of which are well fupplied with great guns. There are ten large mofques, and fifty fmafl ones; three great colleges or public fchools, and a great number of petty ones for children. The houfes are fquare, and built of ftone and brick, with a fquare court in the middle, and galleries all round. There are faid to be about 100,000 inhabitants in the city, comprehending 5000 Jewiffi families, befides Chriftians. There are four fundics, or public inns, fuch as are in Turkey ; and fix cazernes, or barracks, for the unmar¬ ried Turkiflifoldiers, which will hold 600 each. There are no inns for Chriftians to lodge at; but only a few tippling huts kept by flaves, for the accommodation of Greeks and the poorer fort of travellers, where any thing may be had for money. Here are bagnios, or public baths, in the fame manner as in Turkey, at a very moderate rate. The women have baths of their own, where the men dare not come. Without the city there are a great number of fepulchres, as alfo cells or chapels, dedicated to marabouts, or reputed faints, which the women go to vifit every Friday. The Turkifli foldiers are great tyrants; for they not only turn others out of the way in the ftreets, but will go to the farm- houfes in the country for twenty days together, living on free quarters, and making ufe of every thing, not excepting the women. The Algerines eat, as in Turkey, fitting crofs-legged round a table about four inches high, and ufe neither knives nor forks; before they begin, e- very one fays Be ifrite Allah, “ In the name of God.” When they have done, a flave pours water on all their hands as they fit, and then they wafh their mouths." Their drink is water, flierbet, and coffee. Wine is not allowed, though drank immoderately by fome. The pro- fpeft of the country and fea from Algiers is very beau¬ tiful, being built on the declivity of a mountain ; but the city, though for feveral ages it has braved fome of the greateft powers in Chriftendom, it is faid, could make but a faint defence againft a regular liege; and that A L G [ 455 1 A L H Algol, that three Englifh fifty-gun fiu'ps might batter it about Algonqmns the eaig of its inhabitants from the harbour.

In the year 1783 and 1784, they alfo;re¬ newed their attacks-by fea to deftroy the city and gal¬ leys ; but, after fpending a quantity of ammunition, bombs, &c. were forced to retire without either its- capture or extin&iom The mole of the harbour is 500 paces in length, extending from the continent to a fmall ifland where there is a caftle and large battery.

ALGONQUINS, a nation in North America, who formerly pofTefled great trafts of land along the north fhore of the river St Lawrance. For a long time they had no rivals as hunters and warriors, and were long in alliance with the Iroquois ; whom they, agreed to protect from alb invaders, and to let them have a-fhare of their venifon. The 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, fuch as flaying the game, curing the flelh, and drefling the {kins. By degrees, however, the Iroquois aflbeiated in the hunting matches and warlike expeditions of the Algonquins ; fo that they foon began to fancy them- felves as well qualified, either for war or hunting, as their neighbours. One winter, a large detachment, of both nations having gone out a-hunting, and fecured, as they thought, a vail quantity of game, fix young Algon¬ quins and as many Iroquois were fent out to begin, the {laughter. The Algonquins, probably become a little jealous, of their aflbciates, upon feeing a few elks, defired the' Iroquois to return, on pretence that they would have fufficient employment: in flaying the game they fhould kill; but after three days hunting,.having killed none, the Iroquois exulted, and in a day or two privately fet out to hunt for themfelves. The Algon¬ quins were fo exafperated at feeing their rivals return laden with game, that they murdered all the hunters in the night-time. The Iroquois diffembled their re- fentment; but in order to be revenged, applied them¬ felves to ftudy the art of war as pra&ifed among thofe favage nations.. Being afraid of engaging with the Algonquins at firft, they tried their prowefs on other inferior nations, and, when they thought, themfelves fufficiently expert, attacked the Algonquins with fuch diabolical fury, as {bowed they could be fatisfied with nothing lefs than the extermination of the whole race; which, had it not been for the interpofition of the French, they would have accomplilhed.—The few Al¬ gonquin nations that are now to be feen, feem entirely ignorant of agriculture, and fubfift by fifliing and huntr ing.

The inhabitants, though furprifed, and the town with¬ out a garrifon, made a gallant defence: but being at length forced to fubmit, the place was abandoned to the pillage of the Chriflian foldiers; who, not fatisfied with an immenfe quantity of gold and jewels, made flaves of upwards of 3000 of the inhabitants. ALHAMBRA, the ancient fortrefs and refidence of the Mooriftr monarchs of Granada. It derives its name from the red colour of the materials which it was originally built with, Alhambra fignifying a red houfe. It appears to a traveller a huge heap of as ugly build¬ ings as can well be feen, all huddled together, feem- ingly without the leaft intention of forming one habi¬ tation out. of them. The walls are,- entirely unorna¬ mented, all gravel and pebbles, daubed over with pla- fter by a very courfe hand: yet this is the palace of the Moorifh kings of Granada, indifputably the moft curious place within that exiffcs in Spain, perhaps in the world. In many countries may be feen excellent modern as well as ancient architecture, both entire and . in ruins ; but nothing to be met with any where elfe can. convey an idea of this edifice, except the decora-, tions of an opera, or the tales of the genii. Palling round, the corner of the emperor’s palace, . one is admitted at a plain unornamented door in a cor¬ ner. On my firft vifit, fays Mr Swinburne, .1 confefs Travels i*. I was {truck with amazement, as I ftept over the threffiold, to find myfelf on a hidden tranfported into a fpecies of fairy land. The firft place you come to is the court called the communa or del mefucar, that is the common baths; an oblong fquare, with a deep ba- fon of clear water in the middle ; two flights of marble fteps leading down to the bottom ; on each fide a par¬ terre of flowers, and a row of orange-trees. Round the court runs a periftyle paved with marble; the arches bear upon very flight pillars, in proportions and ftyle different from all the regular orders of architecture. The ceilings and walls are incruftated" with fret-work in ftucco, fo minute and intricate, that the moft patient dranghtfman would find it difficult to follow it, unlefs he made himfelf mailer of the general plan. This would facilitate the operation exceedingly; for all this work is frequently and regularly repeated at certain diftances; and has been executed by means of fquare moulds applied fucceffively, and the parts joined together with the utmoft nicety. In every di- vifion are Arabic fentences of different lengths, moft off A L H [ 456 ] A L H Alhambra, of them expreffive of the following meanings: “ There is no conqueror but God;” or, “ Obedience and ho¬ nour to our Lord Abouabdoula.” The ceilings are gilt or painted, and time has caufed no diminution in the frelhnefs of their colours, though conftantly expo- fed to the air. The lower part of the walls is mofaic, difpofed in fantaftic knots and feftoons. A work fo novel, fo exquilitely finiflied, and fo different from all that he had ever feen, muft afford a flranger the moll agreeable fenfations while he treads this magic ground. The porches at the ends are more like grotto-work than any thing elfe to which they can be compared. That on the right hand opens into an oftagon vault, under the emperor’s palace, and forms a perfeft whif- pering gallery, meant to be a communication between the offices of both houfes. Oppofite 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, environ¬ ed with a colonnade 7 feet broad on the frdes and 10 at the end. Two porticos or cabinets about 15 feet fquare, projedt into the court at the two extremities. The fquare is paved with coloured tiles ; the colonnade •with white marble. The walls are covered five feet up from the ground with blue and yellow tiles, dHpofed chequerwife. Above and below is a border of fmall efeutebeons, enamelled blue and gold, with an Arabic motto on a bend; fignifying, “ No conqueror but God.” The columns that fupport the roof and gal¬ lery are of white marble, very flender, and fantaflically .adorned. They are 9 feet high, including bafe and capital, and 84- inches diameter. They are very irre¬ gularly placed ; fometimes fingly, at others in groups of three, but more frequently two together. The width of the horfe-fhoe arches above them is four feet two inches for the large ones, and three for the fmaller. The ceiling of the portico is finifhed in a much finer and more complicated manner than that of the com¬ muna, and the ftucco laid on the walls with inimitable delicacy; in the ceiling it is fo artfully frofted and handled as to exceed belief. The capitals are of vari¬ ous defigns, though each defign is repeated feveral times in the circumference of tire court, but not the leaft attention has been paid to placing them regularly or oppofite to each other. Not the fmalleft reprefen- tation of animal life can be difeovered amidft the va¬ rieties of foliages, grotefques, and ftrange ornaments. About each arch is a large fquare of arabefques, fur- rounded with a rim of characters, that are generally quotations from the Koran. Over the pillars is ano¬ ther fquare of delightful filligree work. Higher up is a wooden rim, or kind of cornice, as much enrich¬ ed with carving as the ftucco that covers the part un¬ derneath. Over this projeCts a roof of red tiles, the only thing that disfigures this beautiful fquare. This ugly covering is modern, put on by order of Mr Wall, the late prime minifter, who a few years ago gave the Alhambra a thorough repair. In Moorifti times, the building was covered with large painted and glazed tiles, of which fome few are ftili to be feen. In the •centre of the court are twelve ill-made lions muzzled, their fore parts fmooth, their hind parts rough, which bear upon their backs an enormous bafon, out of which a leffer rifes. While the pipes were kept in good or- . N° 12. I der/a great volume of water was thrown up, that, fall- Alhambri, ing down into the bafons, pafled through the beafts,y-—wJ and ifiued out of their mouths into a large refervoir, where it communicated by channels with the jet d’eaus in the apartments. This fountain is of white marble, embellifhed with - many feftoons and Arabic diftichs, -thus tranflated : “ Seeft thou not how the water flows copioufly like the Nile >” “ This refembles a fea wafhing over its fttores, threatening ihipwreck to the mariner.” “ This water runs abundantly, to give drink to the lions.” Terrible as the lion is our king in the day of battle.” 4‘ The Nile gives glory to the king, and the lofty mountains proclaim it.” “ This garden is fertile in delights: God takes care that no noxious animal {hall approach it.” “ The fair princefs that walks in this garden, co¬ vered with pearls, augments its beauty fo much, that ■thou may’ft doubt whether it be a fountain that flows, or the tears of her admirers.” Faffing along the colonnade, and keeping on the fouth fide, you come to a circular room ufed by the men as a place for drinking coffee and forbets in. A fountain in the middle refreihed the apartment in fum- mer. The form of this hall, the elegance of its cu¬ pola, the cheerful diftribution of light from above, and the exquifite manner in which the ftucco is defigned, painted, and finiihed, exceed all powers of defeription. Every thing in it infpires the moft pleafing, voluptu¬ ous ideas ; yet in this fweet retreat they pretend that Abouabdoulah affembled the Abencerrages, and cau¬ fed their heads to be ftruck off into the fountain. Con¬ tinuing your walk round, you are next brought to a couple of rooms at the head of the court, which are fuppofed to have been tribunals, or audience-chambers. Oppofite to the Sala de los Ahencerrages is the en¬ trance into the Torre de las dos hermanas, or the tower of the two fifters; fo named from two very beautiful pieces of marble laid as flags in the pavement. This gate exceeds all the reft in profufion of ornaments, and in beauty of profpedt which it affords through a range of apartments, where a multitude of arches ter¬ minate in a large window open to the country. In a gleam of funfhine, the variety of tints and lights thrown upon this enfilade are uncommonly rich. The firft hall is the concert-room, where the women fate; the muficians played above in four balconies. In the middle is a jet d’eau. The marble pavement is equal to the fineft exlfting, for the fize of the flags and even- nefs of the colour. The two fifters, which give name to the room, are flabs that meafure x 5 feet by 74-, without flaw or ftain. The walls, up to a certain height, are mofaic, and above are divided into very neat compartments of ftucco, all of one defign, which is alfo followed in many of the adjacent halls and gal¬ leries. The ceiling is a fretted cove. To preferve this vaulted roof, as well as fome of the other principal cupolas, the outward walls of the towers are raifed 10 feet above the top of the dome, and fupport another roof over all, by which means no damage can ever be caufed by wet weather or exceffive heat and cold. From this hall you pafs round the little myrtle-garden A L H [ 457 3 A L I Alhambra, of LIndaraxa, into an additional building made to the 4”—"v--”—' eaft end by Charles V. The rooms are fmall and low. His dear motto, Plus outre, appears on every beam. This leads to a little tower, proje&ing from the line of the north wall, called El tocador, or the dreffing-room of the fultana. It is a fmall fquare cabinet, in the middle of an open gallery, from which it receives light by a door and three windows. The look-out is charm¬ ing. In one corner is a large marble flag, drilled full of holes, through which the fmoke of perfumes afcend- ed from furnaces below t and here, it is prefumed, the Moorifli queen was wont to fit to fumigate and fweeten her perfon. The emperor caufed this pretty room to be painted with reprefentations of his wars, and a great Variety of grotefques, which appear to be copies, or at leaft imitations, of thofe in the loggie of the Vati¬ can. From hence you go through a long paflage to the hall of ambafladors, which is magnificently de¬ corated with innumerable varieties of mofaics, and the mottos of all the kings of Granada. This long narrow antichamber 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 fquare, 36 high up to the cornice, and 18 from thence to the centre of the cupola. The walls on three fides are r 5 feet thick, on the other 9 ; the lower range of win¬ dows 13 feet high. The whole wall is inlaid with mofaic of many colours, difpofed in intricate knots, ftars, and other figures. In every part various Arabic fentences are repeated. Having thus completed the tower of the upper apart¬ ments, which are upon a level with the offices of the new palace, you defcend to the lower floor, which confifted of bedchambers and fummer-rooms: the back- ftairs and paffages, that facilitated the intercourfe be¬ tween them, are without number. The moft remark¬ able room below is the king’s bedchamber, which communicated, by means of a gallery, with the upper flory. The beds were placed in two alcoves, upon a raifed pavement of blue and white tiles; but as it was repaired by Philip V. who paffed fome time here, it cannot be faid how it may have been in former times. A fountain played in the middle, to refrelh the apartment in hot weather. Behind the alcoves are fmall doors, that conduit you to the royal baths. Thefe confift of one fmall clofet with marble cifterns for waffiing children, two rooms for grown up perfons, and vaults for boilers and furnaces that fupplied the baths with water and the ftoves with vapours. The troughs are formed of large flabs of white marble; the wall are beautified with party-coloured earthen ware ; light is admitted by holes in the coved ceiling. Hard by is a whifpering gallery, and a kind of laby¬ rinth, faid to have been made for the diverfion of the women and children. One of the pafiages of commu¬ nication is fenced off with a ftrong iron grate, and called th» prifon of the fultana; but it feems more pro¬ bable that it was put up to prevent any body from climbing up into the womens quarter. Under the council-room is it long flip, called the hinjf s fiudy; and adjoining to it are feveral vaults, faid to be the place of burial of the royal family. In the year 15 74, four fepulchres were opened ; but as they contained nothing but bones and affies, were immedi¬ ately clofed again. Vcn. I. Part II. This defcription of the Alhambra may be finifhed by obferving how admirably every thing was planned and calculated for rendering this palace the moft vo¬ luptuous of all retirements; what plentiful fupplies of water were brought to refreih it in the hot months of futAmer ; what a free circulation oF air was contrived, by the judicious difpofition of doors and windows; what lhady gardens of aromatic trees; what noble views over the beautiful hills and fertile plains! No wonder the Moors regretted Granada; no wonder they ftill offer up prayers to God every Friday for the re¬ covery of this city, which they efteem a terreftrial pa- radife. See Granada. ALI, gives the denomination to a fe&, or divifion, among- the Mahometans, who adhere to the right of fucceffion of Ali the fourth caliph or fucceffor of Ma¬ homet, and to the reform of Muffulmanifm introduced by him. The feftaries of Ali are more particularly called Schiites; and ftand oppofed to the Sunnites, or feft of Omar, who adhere to the law as left by Maho¬ met, Abubeker, and Omar. Ali was coufin of Maho¬ met, and fon-in-law of that prophet, having married his daughter Fatimah. After Mahomet’s death, great de¬ putes arofe about the fucceffion. Many flood for Ali; but Abubeker was preferred, and defied the firft kalif. Ali took his turn, after the death of Othman.—The Perfians are the chief adherents to the fed of Ali, whom they hold to have been the legitimate fucceffor of Ma¬ homet, and Abubeker an ufurper. On the contrary, the Turks are of the fed of Omar; and hold Ali in execra¬ tion, having raifed a furious civil war among the Muf- fulmans. The diftinguifhing badge of the followers of Ali is a red turban, which is worn by the Perfians, who are hence called in derifion, by the Turks, Kiftlbachi, q. d. red-heads. Ali is reputed the author of feveral works, particularly a Centiloquium, in great efteem among the Arabs and Perfians, part of which has been publifhed in Englifh by Mr Ockley. ALJAMEIA is a name which the Morifcoes in Spain give to the language of the Spaniards. Among other articles agreed on by the junto, which was ap¬ pointed by the emperor Charles V. in 1526, in favour of the Morifcoes, this was one, That the Morifcoes ftiould no longer fpeak Algavareia, i. e. Moorifti or Arabic; but ftiould all fpeak /Hjameia, i. e. Spanifti, as it was called by the Moors, and all their writings and contrads ftiould be in that language.

It was taken from the Moors in 1264.

In confequence of 3his volatility, it always affe&s the olfactory nerves 4 very perceptibly, and its fmell is the general criterion Alkali, by which its ftrength may be judged of. Its attradlion ——v—^ for acids, power of changing colours, &c. are alfo con- fiderably weaker than thofe of the fixed alkalis. Though two forts of volatile alkali are commonly fold under the names of fpirits of hartfhorn and of fal ammoniac, the one differs from the other only in its degree of putity. The former is fo called from its be-. ing originally made from the horns of deer; but this material has long been laid afide, and the bones of horr ■ fes, the flint t, as they are called, of the horns of cat¬ tle, the parings of hoofs, &c. have been fubftiiuted in their (lead. This kind, however carefully- prepared, always contains a portion of animal oil, .the fmell of which is very perceptible; the other, prepared from pure fal ammoniac, is totally free of any empyreuma- tic fmell, and is as pure as it can be obtained by any means whatever. 4 Effervefcence with acids was ■ formerly fuppofed to Effervef- be a diftinguilhing property. of alkalis, though it was ce:'ce wit!Vi always known that by a mixture with quicklime they charlaeri-, might be deprived of this property., . Dr Black, how-‘flic of alC ever, has (hown, that the effervefeing with acids is no kali, property of pure alkali,,but is occafioned only by the efcape of fixed air from it i , of confequence, when quicklime is added,. , which attracts the. whole or great- eft part of the fixed air, no effervefcence can be per¬ ceived. Io the. ftate . in .which the, fixed alkalis are commonly met with, indeed, .effervefcence. with acids may be faid to be an effential property ; .but this is enr tirely owing to the .caufe juft mentioned, viz. a quan¬ tity of fixed air, .to. which they are united during the procefs by which they were originally formed. The quantity of . this air, however, is never fo great as to faturate them entirely; on the contrary, their alkaline properties are always very perceptible, and they are commonly faid to be in a mild ftate. But the truth is, that now they are in a kind of intermediate ftate between what may be called perfedlly mild and per- feftly cauftic. In their perfe&ly mild ftate, they are united with fuch a large quantity of fixed air as en¬ tirely overpowers their alkaline properties ; and there¬ fore they are no more intitled to the name of alkalis in this ftate, than when combined with the marine, ni¬ trous, or any other acid; in which cafe the compounds, are called neutral falts. But it is a much .more labo- . rious and tedious procefs to faturate an alkali com¬ pletely with fixed air than with any other acid; nor, does it very eafily retain the aerial acid after it has once been combined with it., Hence the cauftic tafte- and properties of the alkali almoft always, predominate^ and the fait contains a portion of pure and cauftic al¬ kali, to which alone its virtues are to be aferibed. ^ Vegetable alkali is obtained in its greateft purity by Prep: ratioa, deflagrating nitre with charcoal, provided we make ufe,°f the ve- 1] of no more of the latter than is barely fufficient to de- .Setahie al» ftroy the nitrous acid. It is, however, a very difficultka '* matter to adjuft thi? proportion with fufficient ac¬ curacy ; for if we employ too much charcoal, the fait, will be confiderably phlogifticated; if too little, fome part of the nitre will remain undecqmpofed. Burnt tartar therefore, purified by folution and filtration, may be looked upon as the belt alkali we have. The com¬ mon alkalis, or ajhes as they are called, and faid to b& obtained from the allies of vegetables, are always mix¬ ed Alkali. A L K [46 A Alkali, ed with much phlogifton, and fometxmes with lime, .. , fait, or other hetei-ogeneous matters ; for which rea- .1 fon they are not to be employed in the nicer chemi¬ cal experiments, without being purified by folution in water, by filtration, and cryftallization. The pureft of all thefe falts is that called the blue pearl, imported 6 from Hungary. * Its peculiar The vegetable alkali when thus purified, and con- ij properties. ta;ning near one half its weight of fixed air, is of a white colour when dry, with a very hot and caullic tafte, polfeffing in an eminent degree all thofe qualities which have been afcribed to the alkaline falts in ge- Ineral. It runs per deliquhmi when expofed to the air; and is ufually incapable of being chryftallized, though it acquires this property after being employed in the rectification of ardent fpirit. It adheres more clofe- ly to acids than any fubftance hitherto difeovered; though, from fome experiments, Bergman was induced to believe that pure terra ponderofa attra&ed acid's ftill more powerfully. But this has been difeovered to be a= miftake by Dr Withering, who, in a- paper publifhed in the 74th volume of the Philofophical Tranfa&ions-, Ihows, that unlefs where the earth is united with vi¬ triolic acid, not only the vegetable, the fofiil, but even the volatile alkali in its pure or cauftic ftate, will fepa- rate it from any other with which it may be combined; Terra ponderofa, therefore, will always decompofe vi- triolated tartar, Glauber’s fait,' or vitriolic ammoniac ; whence the miftake of this celebrated chemift probably has proceeded. After this alkali has been once united -with marine acid, it-appears to have undergone fome change; for the fait then produced, by combining it with the vitriolic acid, refembles Glauber’s fait almofi as much as it docs vitriolated tartar. It feems there¬ fore to have made fome approach towards the nature of foffil alkali; but chemifts have not inquired what would be the confequence of repeated combinations of 7 this kind.

The knowledge of this fait was loft in the general obfeurathm of feienee which took place on the decline of the Roman empire ; nor do we find it mentioned till the time of the Hon. Robert Boyle; and, even fince that time, though M du Ha¬ mel gave an accurate account of it in a memoir for the year 1736, little farther notice was taken of it till p very lately. Faund na- We are now certainly informed that the foffil alkali tive in ma- is found native in many parts of the world, which ne- the^worlcf ver ‘s t^le ca^e w’t^1 ^ie vegetable alkali.

Foffii alkali is the natural baits of fea-falt; and could any method of readily procuring it from this fait be fallen upon, it would no doubt be a moft valuable fecret. Hitherto, however, all the methods ufed with any fuc- cefs by the ehemifts may be reduced to two. 1. By mixing the nitrous acid with fea-falt in a retort, in the proportion, according- to Dr Vogel, of four of the acid to one of the fait, and' diftilling off the muriatic acid, or rather aqua regia, which will be produced in ■ the procefs.. The .reiiduum-will afford a cubical nitre by cryftallization, from whence the alkali may' be ob¬ tained pure by deflagrating with charcoal. 2. By ad¬ dition of vitriolic acid the ipirit of fea-falt will be ex¬ pelled much more eafily, and at a cheaper rate, than by the nitrous acid. The refiduum • affords Glauber’s lalt in great plenty : this being melted in a crucible with a fufficient quantity of charcoal-duft, forms a hepar fulphuris ; which being decomppfed by means of the vegetable acid, the latter may be deftroyed by force of fire, and the alkali obtained in purity. - Eor a fur* then- explanation of both thefe methods, fee the article Chemistry, Index. The demand in this country for foffil alkali is fup¬ plied from the afhes of kali and other fea plants, from which it is feparated in the.fame manner as the vege¬ table alkali from the aflies of other plants. The pureft kind of aflies containing this fait is called foda or ba¬ rilla, and is imported chiefly from foreign countries ; that which is obtained from the fea-weed growing on our own coafts, and known by the name of kelp, is exceffively impure, and fcarce admits of being tho¬ roughly analyfed according to the rules of chemiftry. - Jr Both thefe alkalis may be deprived of their fixed Properties air, and thus rendered pure and cauftic, by the addi- “I l oth Ac¬ tion of quicklime. In this ftate the difference between them is much lefs perceptible than in any other, thougff g;c> the addition of fixed air, or any other acid, always fttows that no effential change has taken place in either. In this highly .cauftic ftate they deftroy. the parts of animals in a manner fimilar to that of fire; whence . they are called potential cauteries, as the former is called the afiual cautery. M. Morvean informs us, that on digefting a piece of beef in a foktion of cau¬ ftic vegetable alkali, the liquor fo©n became red, and the fleftri affiimed the form of a famitranfparent jelly, in which, however, one could eafily perceive the ra¬ mifications of the fmalleft fibre ; and, after {landing fome months, it emitted but very little fmell. The vegetable alkali is commonly made ufe of as the mate¬ rial for the common cauftic or lapis inftmalis oi the fliops 5 for the preparation of which, fee Chemistry, Index. Both alkalis attraft moifture from the air when reduced to a folid form in their cauftic ftate, though neither the foffil alkali nor its combinations do fo in any other cafe.

'—^ v Alkalis promote tire fecretions in general, particu¬ larly by the kidneys ; but by the help of warm liquors and bed-clothes, their operation may be diredled to¬ wards the fkin. They have alfo been employed in cafes of heartburn, and others where an acid prevails in the ftomach and bowels, or where thefe organs are loaded with vifcid phlegm. They are likewife given with a- view to affift the operation of the bile when it is too weak and inert, either by themfelves, or mixed with, purgative or other medicines. The foffil alkali has been alleged to be a more powerful folvent of the hu¬ man calculus than the vegetable, though perhaps with¬ out any juft foundation. It is given from 5 to 20 grains three times a-day; and in fome cafes even to double that quantity. It may be taken in any common li¬ quor, or in clear broth made of lean meat, from which the fat has been flammed off; or the powdered falts may be made up into pills or bolufes mixed with li¬ quorice powder, by means of mucilage of gum Arabic or conferve. 16 The vegetable alkali has long been ufed as a diuretic Are of con» in dropfies with great fuccefs; and Dr Monro informs^ us, that he has feen a number of cafes of anafarca in pies> which the water was carried off by it. As diuretics, it may be taken from ten grains to half a drachm, or more, two or three .times a-day, mixed with fome di- ftilled water, fyrup, broth, or water-gruel, or with two- ounces of white-wine, which partly neutralizes the fait- When added to infufions of juniper-berries, broom-tops, horfe-radifb, muftard-feed, winter’s-bark, &c. in wine and beer, they prove powerful diuretics; and Dr Monro gives the following formula. “ Take broom-tops, horfe-radiffi, and juniper-ber¬ ries, of each an ounce ; bruife them in a ftone or marble mortar ; put them into a large wide-mouthed bottle, and add to them an ounce of fait of tartar and two- quarts, of Rheniffi wine. Infufe them for four days;, decant off the wine, and filter it through paper for ufe* Two or three ounces may be taken three or four times a-day.” Or, “ Take an ounce of canella alba, and as much muftard-feed and juniper-berries; bruife them well in an iron mortar, and add an ounce of purified vegetable alkafi with two quarts of porter: infufe for four days, and filter the liquor through paper; let the patient take a wine-glafs full every four or fix hours.” The diuretic powers of thefe medicinesare fometimes- increafed by opiumj and theyj have been fuccefsfully joined with effential oils and balfams.

Dr Hartley, likewife, laboured under this complaint; and believing that the efficacy of Mrs Stephens’s medicines depended on the foap, lime, and alkaline falts which they contained, ordered a pafte to be prepared for himfelf, made of eight ounces of foap, one of oyfter- fhell lime, a drachm of fait of tartar, and relieved, and fome of them feemed to be cured ; that fome few of thofe who had the confirmed ftone, received eonfiderable relief for a time from its ufe: but the com¬ plaints afterwards returned; ndf can he fay that one com¬ plete cure was made; though from the accounts given by the late Dr Whytt of Edinburgh, and others, it fhould appear that this had fometimes happened : that in s much water as formed the whole into afoft mafs; of many cafes of ftone the ley occafioned pain and irrita- which he took large quantities, and found himfelf tion, and increafed the violence of the fymptoms fo greatly relieved, though not cured, as a ftone was found in his bladder after his death. Thefe and other in- ftances of fuccefs, foon brought the medicines into ge¬ neral ufe : but though many found relief from them, others, particularly thofe who were affi idled with the ftone, had all the fymptoms of their diftemper aggra¬ vated, by the falts rendering the blood, and other li¬ quors of the body, particularly the urine, ffiarp and a- crid, fo as to irritate and inflame the bladder, which was already in too irritable a ftate, from the conftant fri&ion of the calculus lodged within it. The late ex¬ periments of Mr Scheele and Sir Torbern Bergman, however, have made it evident, that the human calcu¬ lus is compofed of a concrete acid joined to a fmall por¬ tion of animal earth, Moft people, therefore, who are affiidled with the ftone or gravel, wifh to try the effi¬ cacy of thefe remedies, rather than fubmit to the dan¬ gerous operation of lithotomy ; we fhall therefore fub- man who had taken it, and who had found confider- much, that the patients were obliged to lay it afide ; and that this happened moft frequently where the blad¬ der feemed to be already difeafed from the irritation of the ftone : that at all. times it is advifable to lay afide this medicine, at leaft for a time, whenever it irritates and occaftons pain, or where there are appearances of its continued ufe having broken down the crafis of the blood. Inftead of the foap-ley, the following folution of vegetable alkali, fully faturated with fixed air, has been rtecoa^ lately recommended as a powerful folvent of the ftone. mended. “ Take two ounces of fait of tartar, and diffolve it in two quarts of diftilled water, and then faturate it fully with fixed air ; and let the patient take eight ounces of it every eight hours. But though many cafes have been related in which this medicine is faid to have been ferviceable, our author fays he has feen only one gentle- join, from Dr Monro, the following direftions for ma- j8 king and ufing the foap-ley. "Monro’s “ Take of fait of tartar, eight ounces; of freffi quick- direftions lime, four ounces; of diftilled water, a quart: mix and ^en} ‘I11 weft together in a large bottle, and let them the toap- ftand f°r 24 hours ; then pour off the ley and filter it ley. through paper, keeping it in well-ftopped vials for ufe.

Soap-ley has likewife been recom¬ mended as a folvent of bilious calculi, and has fome¬ times been of fervice; but this has probably arifen more from its property of diffolving thick and vifcid hu¬ mours, and affifting the aftion of the bile, than by adling on the calculi themfelves. 20 The volatile alkali has many of the virtues of the Medical fixed, but affedls animal fubftances, particularly in its cauftic ftate, lefs powerfully than they do. It gives a a 1 brifli and ftrong ftimulus to the nerves and fibres of li¬ ving animals; and is therefore employed in difeafes mix the quantity to be ufed in the day with three pints where the pulfe is low and the circulation too languid; of plain broth, which has been made with the lean’part of veal, with all the fat or oily parts feparated from it, by putting it, when made, into a large bowl, and flam¬ ming them off with a fpoon when cold, and to drink, within an hour, a pint of this broth three times in the day—early in the morning—ut noon—and in the even¬ ing ; and to continue the ufe of this medicine for three, four, or more months ; and, during this courfe, to live on fuch things as leaft counteraft the operation of the medicine : to take for breakfaft fome plain broth, fuch as has been defcribed, with dry toafted bread or bifcuit; or a dilh or two of tea or coffee in place of the broth: for dinner, to eat the lean part of plain boiled orroaft- ed meat, or a fowl, with their own gravy or juice for fauce ; and to eat only of vegetables which contain but little acid, fuch as potatoes, &e. and to ufe for drink in low' fevers, where the patient is in danger of fink¬ ing ; in apople&ic and lethargic diforders of elderly people of phlegmatic habits, in paralytic cafes, faint¬ ing fits, &c. where a brifk and ftimulating remedy is wanted. It is often ufed as a diaphoretic and fudorific in cafes of rheumatifm, in the end of fevers, catarrhs, and other difeafes, where a plentiful diaphorefis or fweat is required; and, according to our author, it is prin¬ cipally owing to this quality that the alkalis have ob¬ tained their reputation of being efficacious remedies againft the bites of ferpents and other venomous ani¬ mals. It is equally efficacious againft mineral acid poifons with the fixed alkali. ar It now remains only to give fome account of the o- Origin rigin of the alkalis, or that procefs by which they are a|kalin$ naturally produced.

Chemifts have been drinking wine, beer, cyder, punch, and in ftiort from divided in their opinions, whether alkaline falts be na- N® 12. tural A L K [ 465 ] A L K Alkali, tural bodies, or formed by the force of fire, uniting the ' principles of which they confift in the burning or di- fiilling the fubftances from which they are got. It is generally fuppofed that they are formed by the force of fire intimately uniting an earth, an acid, and an in¬ flammable matter together, fo as to form an alkaline fait, which is fuppofed to be compofed of thefe prin¬ ciples. In fupport of this opinion, it has been alleged, 1. That the fiKed vegetable alkali is produced by burn¬ ing vegetables which contain the principles fit for form¬ ing thefe falts; though no veftige of an alkali can be difcovered in thefe vegetables in their natural ftate. 2. That the effential falts of vegetables, which contain an acid and an earth, on being calcined in a crucible with charcoal, yield an alkaline fait. 3. That by al¬ ternately allowing the vegetable alkali to run per deli- quium, and drying it again, it precipitates a quantity of earth every time it is diflblved; fo that the whole of the fait is at lafl: reduced to this kind of earth, vrhile the acid, phlogifton, &c. have evaporated, or been de- ftroyed by the repeated application of heat for drying the fait. 4. In like manner the volatile alkaii is pro¬ duced by diftilling animal fubftances which contain the principles fit for producing it, though no marks of a volatile alkali could be difcovered in thefe fubftances while they were frelh. On the other hand, it has been aflerted, that the al¬ kaline falts obtained by burning vegetables, or diftilling animal fubftances, exifted originally in the materials from which they are procured ; that they were gene¬ rated in the plants by the procefs of vegetation, and freed by the fire from the other principles which dif- guifed them. In fupport of this opinion the following arguments are made ufe of by Mellrs Weigleb, Rofen- ftiel, Morveau, &c. 1. That they had not been able to procure an alkaline fait by mixing earths, oil, and acids together, and fubje&ing them to the moft intenfe fire. 2. The cryftals of tartar, which were formerly believed to be pure acid falts, have been found by late experi¬ ments to contain a vegetable alkali. 3. The vegetable alkaline fait, when purified, is always of the fame na¬ ture, from whatever fubftance it is procured ; and therefore muft have been an original principle or body exifting in the vegetables from which it is procured: for had it been produced by art, it would have varied, and we fhould have had different fpecies of it, accor¬ ding to the principles which the plants contained. And, 4, The neutral falts which have been found mix¬ ed with the afhes of plants, as vitriolated tartar, nitre, and fea-falt, are likewife ftrong proofs of the original exiftence of alkali in vegetables. On this fubjedt Dr Monro obferves, that hitherto we have not fufficient evidence to determine pofitively whether the vegetable alkali be produced by the force of fire, or if it exifted originally in the fubftances from which it is prepared, though he is inclined to favour the former opinion. With regard to the volatile al¬ kali, however, we have abundant evidence of its being produced from fubftances which could not pofiibly be fuppofed to contain it originally. Dr Stahl affures us, that if any dry fixed alkaline fait be well rubbed in a mortar with fuch a quantity of oil of turpentine as is fufficient to make it of the confidence of a pulp, and digefted for fome weeks in a cucurbit or retort, we ob¬ tain a volatile alkali. Mr Geoffroy relates, that having Vol.I. Part II. placed a large retort in a fand furnace, and adapting a Alkali tubulated receiver to it, afterwards heating the hot- .„ - , , . , . . . ^ -All-Saints, tom ox the retort red not, he put into it, by means 01 , a long tube rifing from the upper part of the neck, a powder compofed of equal parts of nitre and charcoal, on which there came over into the receiver a liquor highly impregnated with volatile alkali. Cartheufer, in the firft volume of his Materia Mcdica, tells us, that if two parts of fait of tartar be mixed with one of ful- phur, and be afterwards diftilled, they yield a volatile alkaline fait and fpirit. Boerhaave and Macquer have both affirmed, that the vegetative procefs itfelf produ¬ ces a volatile alkali; and that the juices got by bruifing muftard-feed and other alkalefcent vegetables, as they are called, contain a volatile alkali which effervefces with acids: but this is denied by Cartheufer and Vo¬ gel, who affirm that they could difcover no traces of volatile alkali in thefe juices by any experiments they made. But whatever may be concluded from the experience of former chemifts, the late difcoveries of Dr Prieftley and Mr Cavendifti have decifively fliown, that the vola¬ tile alkali is by no means a Ample element or natural principle, but a compound, and which may be artifi¬ cially prepared. Dr Prieftley informs us, that by the See Aeroli- union of nitrous air with iron, a volatile alkali is gene- gy, n° 149- rated ; and Mr Cavendifh, that by the aftion of the electric fluid, or pure elementary fire, upon phlogifti- cated air, the nitrous acid is produced: the volatile al- See Acid, kali, therefore, muft be fuppofed to confift ultimately n° 7* of phlogifticated air united to a great quantity of ele¬ mentary fire. In Iik<^mar>ier, if we can fuppofe this fubtile element to enter into the fubftance of any kind of earth in fuch a manner as to exert its peculiar action when that fubftance is applied to any other, we may reafonably conclude that the fixed alkalis alfo are not Ample and permanent principles, but capable of artifi¬ cial compoiition and decompofition. It is certain that the aftion of alkaline falts is extremely fimilar to that of fire ; and as we know that this element is combined in a latent ftate with fluids, there can be no abfurdity in fuppofing it capable of combining alfo with folids.

No Latin was ever more devoted to the fee ef Rome, or more inveterate againft the Greek fchif- matics, than Allatius. He never engaged in matri¬ mony, nor was he ever in orders; and Pope Alexan¬ der VII. having afked him one day, why he did not en¬ ter into orders ? he anfvvered, “ Becaufe I would be free to marry.” The pope rejoined, “ If fo, why do you not marry ?” “ Becaufe,” replied Allatius, “ I would be at liberty to take orders.” Thus, as Mr Bayle obferves, he paifed his whole life, wavering be¬ twixt a parifh and a wife; forry, perhaps, at his death, for having chofen neither of them; when, if he had fix¬ ed upon one, he might have repented his choice for 30 or 40 years.—If we believe John Patricias, Allatius had a very extraordinary pen, with which, and no o- ther, he wrote Greek for 40 years ; and we need not be furprifed, that, when he loft it, he was fo grieved, that he could fcarce forbear crying.

ALLEGEAS, or Allegias, a fluff manufactured in the Eaft-Indies. There are two forts of them ; fome are of cotton, and others of feveral kinds of herbs, which are fpun like flax-and hemp.

ALLEGIANCE, in law, is the tie, or ligamen, which binds the fubjeft to the king, in return for that. protection which the king affords the fubjedt. The thing itfelf, or fubftantial part of it, is founded in rea- fon and the nature of government; the name and the form are derived to us from our Gothic anceftors. Un¬ der the feodal fyftem, every owner of lands held them in fubjedtion to fome fuperior or lord, from whom or from whofe anceftbrs the tenant or vaffal had received them : and there was a mutual truft or confidence fubfifting between the lord and vaffal, that the lord ftiould proteft ~ the vaffal in the enjoyment of the territoryhe had granted him; and, on the other hand, that the vaffal fhould be faithful to the lord, and defend him againft all his enemies. This obligation on the part of the vaffal was called his /f- delitas or fealty : and an oath of fealty was required by the feodal law to be taken by all tenants to their land¬ lord, which is couched in almoft the fame terms as our ancient oath of allegiance; except that, in the ufual oath of fealty, there was frequently a faving or exception of the faith due to a fuperior lord by name, under whom the landlord himfelf was perhaps only-a tenant or vaf¬ fal. But when the acknowledgment was made to the abfolute fuperior himfelf, who was vaffal to no man, it' was no longer called the oath of fealty', but the oath of allegiance ; and therein the tenant fwore to bear faith to his fovereign lord, in oppofition to all men, without any faving or exception. Land held by this exalted fpecies of fealty, was called fiudum ligium, a liege fee ; the vaffals homines ligii, or liege men; and the fovereign, their dominus ligius, or liege lord. And when fovereign princes did homage to each other for lands held under their refpeftive fovereignties, a diftinftion was always made between fimple homage, which was only an ac¬ knowledgement of tenure ; and liege homage, which in¬ cluded the fealty before-mentioned, and the fervices confequent upon it. In Britain, it becoming a fettled principle of tenure, that all lands in the kingdom are holden of the king as. their fovereign and lord para¬ mount, no oath but that of fealty could ever be taken to inferior lords ; and the oath of allegiance was ne- cefiarily confined to the perfon of the king alone. By an eafy analogy, the term of allegiance was foon brought to fignify all other engagements which are due from fubjedls to their prince, as well as thofe duties which were fimply and merely territorial. And the oath of allegiance, as adminiftered in England for upwards of 600 years, contained a promife “ to be true and faith- u ful to the king and his heirs, and truth and faith to “ bear of life and limb and terrene honour, and not to “ know ?!i Allegiance ilmmtnt. ALL [ 467 1 ALL 11 know or kear of any ill or damage intended him, in dan t fuch llranger transfers himfelf from this king- Al!eg«ry. “ without defending him therefrom.” But, at the re- dom to another. Natui-al allegiance is therefore per- volution, the terms of this oath being thought perhaps petual, and local temporary only; and that for this rea- to favour too much the notion, of non-reiidance, the fon, evidently founded upon the nature of government. That allegiance is a debt due from the fubject, upon an implied contradb with the prince; that fo long as the one affords protection, fo long the other will demean him¬ felf faithfully. The oath of allegiance, or rather the allegiance it- prefent form was introduced by the convention parlia¬ ment, which is more general and indeterminate than the former; the fubjeCt only promifing “ that he will “ be faithful and bear true allegiance to the king,” without mentioning “ his heirs,” or fpecifying in the ^ lead wherein-that allegiance confids. The oath of fu- felf, is held to be applicable, not only to the political premacy is principally calculated as a renunciation of capacity of the king, or regal office, but to his natural the pope’s pretended authority : and the oath of abju¬ ration, introduced in the reign of King William, very amply fupplies the loofe and general texture of the oath of allegiance ; it recognizing the right of his majedy; derived under the aft of fettle.ment; engaging to i'up- port him to the utmod of the juror’s power; promifing to difclofe all traiterpus confpiracies againd him ; and perfon and blood-royal: and for the mifapplication of their allegiance, viz. to the regal capacity or crown, exclufive of the perfon of the king, were the Spencers banidied in the reign of Edward II. And from hence arofe that principle of perfonal attachment and affec-? tionate loyalty, which induced our forefathers (and, if occafion required, would doubtlefs induce tlieir fons) to exprefsly renouncing any claim of the defcendants of hazard all that was dear to them, life, fortune, .and fa-i the late pretender, in as clear and explicit terms as the Engliffi language can furnifh. This oath mud be ta¬ ken by all perfons in any office, trud, or employment ; and may be tendered by two judices of the peace to any perfon whom they fhall fufpedt of difaffedlion. And the oath of allegiance may be tendered to all perfons above the age of twelve years; whether natives, deni¬ zens, or aliens. But, befides thefe exprefs engagements, the law alfo holds that there is an implied, original, and virtual al¬ legiance, owing from every fubjedl to his fovereign, an¬ tecedently to any exprefs promife, and although the .fubjedd .never fwore any faith or allegiance in form. mily, in defence and fupport of their liege lord and fo¬ vereign. It is to be obferved, however, in explanation of this- p hy's Mo- allegiance, That it does not preclude refidance to tlxeral and Po¬ king, when his mifcondudt or weakncfs is fuch as toL,tical’ pbi- make refidance beneficial to the community. It feems ■y’ fairly prefumable, that the convention parliament, which introduced the oath of allegiance in its prefent form, did not intend to exclude all refidance; lince the very authority by yvhich the members fat together, was it- felf the cdecl of a fuccefsful oppofition to an ackhoW- ledged fovereign. Again.: The allegiance above defcribed can only be Thus Sir Edward Coke very judly obferves, that “all underdood to fignify obedience to lawful commands. fubjedds arc equally bounden to their allegiance as if they had taken the oath ; becaufe 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 fame.” Allegiance, both exprefs and implied, is however di- ftinguidied by the law into two forts or fpecies, the one natural, the other local; the former being alfo perpe¬ tual, the latter temporary. Natural allegiance is fuch as is due from all men born within the king’s dominions immediately upon their birth.

How common is it for Writers, who affeft to be comic, when in want of other means for raihng a fmile, to ufe af¬ fected ahiteration with fuccefe. But, in the fine arts, no beauty nor grace is beyond the power of ridicule. The nobleft attitudes in painting have been rendered laughable by caricatura. St Paul preaching at Athens, in the defign of Raphael, appears elegant, noble, and in fome degree awful. The fame apoftle, reprefented by Hogarth in nearly the fame attitude, pleading be¬ fore the governor Felix, feems altogether ridiculous. So the language and verfification of Milton in the Pa- radife Loft appear only proper for the moft elevated fubjefts. In the Splendid Shilling of Philips, they appear equally proper for the loweft. So fares it alfo with alliteration. Nor ought we to be mortified at the difcovery, that much of the delight afforded by verfi¬ fication arifes from a caufe fo-pitiful as the repetition of the fame letter twice, or oftener, on the accented parts of a verfe; ifor there are many other caufes of pleafure, which, when thus detefted and taken to pie¬ ces, feem equally contemptible. We apprehend the principal operation of this orna¬ ment to be quite mechanical. It is eafier for the or¬ gans of fpeech to refume, at ftiort intervals, one cer¬ tain. conformation, than to throw themfelves into a number of different ones, unconnected and difcordant. Tor example, a fucceffion of labials, interfperfed at regular diftances with dentals and gutturals, will be more eafily pronounced than the fuccefiion of all the three at random. Sounds of which the articulation is eafieft, are moft completely in the power of the fpeaker. He can pronounce them flowly or rapidly, foftly or with force, at pleafure. In this we imagine the power and advantage of alliteration is founded: for we would not lay any ftrefs on the pleafure which can refult to the ear from the repetition of the fame letter. It has been compared to the frequent returns of the key-note in a mufical ftrain ; but that analogy is extremely faint. The ear, we prefume, can be pleafed with alliteration only in fo far as it contributes to the fuperibr eafinefs of recitation ; for what is reci¬ ted with eafe muft be heard with pleafure. Thefe remarks might be confirmed and illuftrated by numberlefs paffages from the bell poets. Some few lines will fuffice, taken from Grey, wdio feems to have -paid particular attention to this grace. He profeffed to have learned his verfification from Dryden, as Dry- den did from Spencer ; and thefe three abound in alliteration above all the Englilh poets. We choofe Grey for another reafon, in proof of what we men¬ tioned before, that alliteration contributes not only to the f'weetnefs, but alfo to the energy, of verfification; for he ufes it chiefly when he aims at ftrength and boldnefs. In the Sifter Odes (as Dr Johnfon ftyles them), almoft every ftrophe commences and concludes with an alliterative line. The poet, we fuppofe, wilh- ed to begin with force, and end with dignity. “ Ruin feize thee, ruthlefs king.” “ To ^igh-born Abel’s />arp, or foft Llewe/lyn’s /ay.” “ /Feare the warp, and weave the woof.” “ Stamp we our vengeance ^ « and feldom appear but amongft the grandees and rich men. The common people have alfo their Alme. They are girls of the fecond clafs, who try to imitate the former; but they have neither their elegance, their graces, nor their knowledge. They are every where to be met with. The public places and the walks about Grand Cairo are full of them. As the populace re¬ quire allufions ftill more ftrongly marked, decency will not permit the relation to what a pitch they carry the licentioufnefs of their geftures and attitudes. ALMEDIA, a frontier-town of Portugal, in the province of Tralos Montes, on the confines of Leon, where there was a very brilk adtion between the French and Pprtuguefe in 1663 ; 17 miles N.

ALMEHRAB, in the Mahometan cuftoms, a nich in their mofques, pointing towards the kebla or temple of Mecca, to which they are obliged to bow in pray¬ ing. See Kebla. ALMEISAR, a celebrated game among the an¬ cient Arabs, performed by a kind of calling of lots witli arrows, ftrictly forbid by the law of Mahomet, on account of the frequent quarrels occafioned by it. The manner of the game was thus: A young camel being brought and killed, was divided into a number of parts. The adventurers, to the number of feven, being met, 11 arrows were provided without heads or feathers ; feven of which were marked, the firft with one notch, the fecond with two, the third with three, &c. the other four had no marks. Thefe arrows were put promifeuoufly into a bag, and thus drawn by an indifferent perfon. Thofe to whom the marked ar¬ rows fell, won Ihares in proportion to their lot; the • reft to whom the blanks fell, were intitled to no part of the camel, but obliged to pay the whole price of it. Even the winners tailed not of the flefh themfelves more than the lofers, but the whole was diftributed to the poor. ALMENE, In commerce, a weight of two pounds ufed to weigh faffron in feveral parts of the continent of the E. Indies. ALMERIA, a fea-port town in the kingdom of Granada in Spain, pleafantly fituated in a fine bay at the mouth of the river Almeria, on the Mediterranean-: W. Long. 3. 20. N. Lat. 36. 51. This town is by fome thought to have rifen upon the ruins of the an¬ cient Abdera, and was formerly a place of great con- fequence. It was taken from the Moors in 1147, by * the emperor Conrad III. in conjunction with the French, Genoefe, and Pifans.—It was at that time the ftrongeft place in Spain, held by the infidels ; from which their privateers, which were exceedingly nume¬ rous, not only troubled the fea-coafts inhabited by the Chriftians, but gave equal difturbance to the maritime provinces of France, Italy, and the adjacent iflands. The city being well fortified, having a ftrong caftle, a numerous garrifon, and being excellently provided with every thing neceffary, made a vigorous refiftance; but was at laft taken by ftorm, when the viftor put to the fword all the inhabitants who were found in arms, diftributing the bell part of the plunder among his al- 3 P fcsi A L M [ 482 ] A L M Almeria lies, whom he fent away thoroughly fatisfied. The Almoner Genoefe, particularly, acquired here that emerald vef- « ^ *. fel which ftill remains in their treafury, and is deemed invaluable. Upon its reduction by the Chriftians Almeria be¬ came a bifhopric ; but is at prefent very little better than a village, indifferently inhabited, and has nothing to teflify fo much as the probability of its former great- nefs, except certain circumftances which cannot be effaced even by the indolence of the Spaniards them- of the almoner; alfo the place where alms felves. What thefe are, Udal ap Rhys, a Wehhman, See Ambry, ihus defcribes, in his tour through Spain and Portugal. “ Its climate (fays he) is fo peculiarly bleffed, that one really wants words to exprefs its charms and excel¬ lence. Its fields 6nd meads are covered with flowers all the year round ; they are adorned alfo with palms, myrtles, plane-trees, oranges, and olives ; and the moun- the highefl: eccleflailical dignity in that kingdom. To hint belongs the fuperintendency of all hofpitals and houfes of lepers. The king receives the facrament from his hand ; and he fays mafs before the king in all grand ceremonies and folemnities. Almoner is alfo a more fafhionable title given by fome writers to chaplains. In this fenfe we meet with almoner of a fhip, almoner of a regiment. ALMONRY, or Aumbry, the office or lodgings given. ALMS, a general term for what is given out of cha¬ rity to the poor. In the early ages of Chriftianity, the alms of the charitable were divided into four parts ; one of which was allotted to the bifhop, another to the priefts, and a third to the deacons and fubdeacons, which made tains and promontories near it are as noted for their their whole fubfiftence ; the fourth part was employed producing a great variety of precious ftones,' infomuch that the next promontory to it is called the Cape of Gates, which is a corruption from the word agates, the in relieving the poor, and in repairing the churches. No religious fyftem is more frequent or warm in it exhortations to alms-giving than the Mahometan. The hills thereabouts abounding in that fort of precious Alcoran reprefents alms as a neceffary means to make ftones, as well as in emeralds and amethyfts, granites prayer be heard. Hence that faying of one of their ©r coarfe rubies, and extreme curious alaballer in the mountains of Filaures.” ALMISSA, a fmall but ftrong town at the mouth of the Cetina, in Dalmatia, famous for its piracies ; ten miles eaft of Spalatro.'

Almonds, in anatomy, a name fometimes given to two glands, generally called the tonfls. Almonds, among lapidaries, fignify pieces of rock- eryftal, ufed in adorning branch-candleilicks, &c. on account of the refemblance they bear to the fruit of that name. AiMOKn-Furnace, among refiners, that in which the flags of litharge, left in refining filver, are reduced to lead again by the help of charcoal. ALMONDBURY, a village in England, in the weft-riding of Yorkftiire, fix miles from Halifax. ALMONER, in its primitive fenfe, denotes an officer in religious houfes, to whom belonged the management and diftribution of the alms of the houfe. By the an¬ cient canons, all monafteries were to fpend at leaft a tenth part of their income in alms to the poor. The almoner of St Paul’s is to difpofe of the monies left for charity, according to the appointment of the donors, khaljfs : “ Prayer carries us half-vrty to God, faffing brings us to the door of his palace, and alms introduces us into the prefence-chamher.” Hence many illuftri- ous examples of this virtue among the Mahometans. Hafan, the fon of Ali, and grandfon of Mohammed, in particular, is related to have thrice in his life divided his fubftance equally between himfelf and the poor, and twice to have given away all he had. And the gene¬ rality are fo addicted to the doing of good, that they extend their charity even to brutes. Alms, alfo denotes lands or other effecfts left to churches or religious houfes, on condition of praying for the foul of the donor. Hence, Free Alms was that wdiich is liable to no rent or fervice. Reafomble Alms was a certain portion of the eftates of inteftate perfons, allotted to the poor. Alms-Box, or Chef, a fmall cheft, or coffer. Called by the Greeks wherein anciently the alms were collefted, both at church and at private houfes. The alms-cheft in Englifh churches, is a ftrong box,, with a hole in the upper part, having three keys, one to be kept by the parfon or curate, the other two by the church-wardens. The erecting of fuch alms-cheft in every chqrch is enjoined by the book of canons, aa alfo the manner of diftributing what is thus collected among the poor of the parifti. Alms-Houfe, a petty kind of hofpital, for the main- to bury the poor who die in the neighbourhood, and tenance of a certain number of poor, aged, or difabled to breed up eight boys to finging, for the ufe of the people. choir. By an ancient canon, all bifhops are required to keep almoners. Lord Almoner, or Lord High Almoner, of Eng¬ land, is an ecclefiaftical officer, generally a bifhop, who has the forfeiture of all deodands, and the goods of frlos de fe, which he is to diftribute among the poor. He has alfo, by virtue of an ancient cuftom, the power of giving the firft difh from the king’s table to what¬ ever poor perfon he pleafes, or, inftead of it, an alms in money. Great Almoner, Grand Aumonier, in France, is ALMUCANTARS, in aftronomy, an Arabic word denoting circles of the fphere paffing through the cen¬ tre of the fun, or a ftar, parallel to the horizon, being the fame as Parallels of Altitude. AiMucANTARs-Staff, is an inftrument ufually made of pear-tree or box, having an arch of 15 degrees; ufed to take obfervations of the fun, about the time of its rifing and fetting ; in order to find the amplitude, and confequently the variation of the compafs. ALMUCIUM, denotes a kind of cover for the head, worn chiefly by monks and ecclefiaftics : It was of a A L M [ 483 ] A L O fj| Almugim fquare form, and feems to have given rife to the bon- 1 II. . nets of the fame Ihape ftill retained in univerfities and A Alnwick. j , x \ - ^ cathedrals. ALMUGIM, or Almug-tree, a certain kind of wood mentioned in the firft book of Kings, (x. 11.) , which the vulgate tranflates iigna thyina, and the Sep- tuagint wrought wood. The Rabbins generally render it coral; others, ebony, brazil, or pine. But it is ob- ferved, that the almug-tree can by no means be coral, becaufe that wood is not fit for the purpofes that the Scripture tells us the ‘almug-tree was ufed, fuch as mu- fical inftruments, Hair-cafes, &c. The word thyinuvi is a name for the citron-tree, known to the ancients, and very much efteemed for its fweet odour and great beauty. It came from Mauritania. The almug-tree, or almugim, algumim, or Amply gummim, taking al for a kind of article, is therefore by the beft commen¬ tators underftood to be an oily and gummy fort of wood; and particularly that fort of tree which pro¬ duces the gum ammoniac, which is alfo thought to be the fame with the Ihittim-wood, whereof there is fuch frequent mention made by Mofes. ALMUNECAR, a fea-port town in thelkingdom of Granada, feated on the Mediterranean, with a good harbour, defended by a ftrong caftle, 20 miles fouth of Alhama. W. Long. 3. 45. N. Lat. 36. 50. ALNAGE, orAuLNAGE, the meafuring of wool¬ len manufactures with an ell. It was at firlt intended as a proof of the goodnefs of that commodity, and ac¬ cordingly a feal was invented as a mark that the com¬ modity was made according to the ftatute ; but, it be- . ing'now poffible to purchafe thefe feals, they are affix¬ ed, whenever the vender pleafes, to all cloaths indifcri- minately, to the great prejudice of our woollen manu¬ factures. ALNAGER, Alneger, or Aulneger, q. d. mea- furer by the ell; fignifies a fworn public officer, who by himfelf, or deputy, is to look to the affize of woollen cloth made throughout the land, i. e. the length, width, and work thereof; and to the feals for that purpofe ordained. The office of king’s aulnager feems to have been derived from the ftatute of Richard I. A.D. 1197, which ordained, that there ffiould be only one weight and one meafure throughout the kingdom; and that the'cuftody of the affize, or ftandard of weights and meafures, ffiould be committed to certain perfons in e- very city and borough. His bufinefs was, for a cer¬ tain fee, to meafure all cloths made for fale, till the of¬ fice was aboliffied by the ftatute 11 and 12 W. III. cap. 20. ALNUS, the Alder-tree, a fpecies of betula. See Betula. Alnus, in the ancient theatres, that part which was tnoft diftant from the ftage. ALNWICK, a thoroughfare town in Northumber- | land, on the road to Scotland. Here Malcolm, king of Scotland, making an inroad into Northumberland, was killed, with Edward his fon, and his army defeated by Robert Mowbray, earl of this county, anno 1092. Likevvife William, king of Scotland, in 1174, inva¬ ding England with an army of 80,000 men, was here encountered, his army routed, and himfelf made pri- foner. The town is populous, and in general well built; it has a large town-houfe, where the quarter- feffions and county-courts are held, and members of parliament elecled. It has a fpacious fquare, in which Alnwick a market is held every Saturday. Alnwick appears to have been formerly fortified, by the veftiges of a > ^ « wall ftill vifible in many parts, and three gates which remain almoft entire. It is governed by four chamber¬ lains, who are chofen once in two years out of a com¬ mon council, confifting of 24 members. It is orna¬ mented by a ftately old Gothic caftle, which has been the feat of the noble family of Piercy, earls of North¬ umberland. As the audits for receipt of rents have ever been in this caftle, it has always been kept in to¬ lerable repair; and not many years ago, it was repaired and beautified by the duke of Northumberland, who made very confiderable alterations, upon a moft elegant plan, with a view to refide in it fome part of the fum- mer-feafon. The manner of making freemen is pecu¬ liar to this place, and indeed is as ridiculous as lingu¬ lar. The perfons who are to be made free, or, as the phrafe is, leap the well, affemble in the market-place, very early in the morning, on the 25th of April, being St Mark’s day. They appear on horfe-back, with e- very man his fword by his fide, dreffed in white, and with white night-caps, attended by the four chamber¬ lains and the c'aftle-bailiff, mounted and armed in the fame manner; from hence they proceed, with mufic playing before them, to a large dirty pool, called Free- man’s-well, where they difmount, and draw up in a body, at fome diftance from the water ; and then ruffi into it all at once, and fcramble through the mud as fall 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, remount their horfes, and ride full gallop round the confines of the dillridl; then re-enter the town, fword in hand, and are met by women dreffed in ribbons with bells and garlands, dancing and finging. Thefe are called timber-wajh. The houfes of the new freemen are on this day diftin- guiffied by a great holly-buffi, as a fignal for their friends to affemble and make merry with them after their re¬ turn. This ceremony is owing to king John, who was mired in this well; and who, as a puniffiment for not mending the road, made this a part of their charter. Alnwick is 31 o miles north by weft from London, 3 3 north of Newcaftle, and 29 fouth of Berwick. Long. 1. 10. Lat. 55. 24. ALOA, in Grecian antiquity', a feftival kept in ho¬ nour of Ceres by the huffiandmen, and fuppofed to re- femble our harveft-home. ALOE, in botany, a genus of the monogynia or¬ der, belonging to the hexandria clafs of plants ; and, in the natural method, ranking under the 10th order, Coronarix. The characters are : There is no calyx; The corolla is monopetalous, ereCt, fix-cleft, and ob¬ long ; the tube gibbous; the border fpreading, and fmall; with a neftary-bearing bottom : The Jlamina confift of fix tabulated filaments, rather furpaffing the corolla in length, and inferted into the receptacle; the anthers are oblong and incumbent: The piftillum has an ovate germen ; the llylus is fimple, the length of • the ftamina ; the ftigma is obtufe and trifid : The pe- ricarpium is an oblong capfule, three-furrowed, three- celled, three-valved : The feeds are many and angular. Of this genus, botanical writers enumerate ten fpecies ; of which the moft remarkable are, x. The diilicha, by fome called the foap aloe, by 3 P 2 others A L O [ 484 1 A L O others calalline aloe. This feldom rifes above two ' feet high. The leaves are very broad at the bafe, where they clofely embrace the ftalk, and gradual¬ ly decreafe to a point. The edges are fet with lharp fpines, and the under leaves fpread open horizon¬ tally every way. Thefe are of a'dark green colour fpotted with white, fomewhat refembling the colour of foft foap, from whence the plant got the name of Jbap-aloe. The flowers grow in umbels on. the tops of the (talks, are of a beautiful red colour, and appear in Augtift and September. 2. The variegata, or partridge-bread aloe, is a low. plant, feldom rifing above eight inches high. The leaves of this are trian¬ gular, and curioufly veined and fpotted, fomewhat like the feathers of a partridge’s breaft. The flowers grow in very loofe fpikes, and are of a fine red colour tip¬ ped with green. 3. The vifeofa, with funnel-fliaped flowers, grows ftear a foot high, with triangular leaves of a dark green colour. The flowers grow thinly upon very (lender footftalks, are of an herba¬ ceous colour, and their upper part turns backward. 4. The fpiralis, with oval crenated flowers^ grows fome¬ what like the former; only tire flowers grow upon tal¬ ler ftalks, which branch out and grow, in very long clofe fpikes, 5. The linguisformae, or tongue-aloe, has its leaves about fix. inches indength, and (haped like a tongue.. The flowers grow in flender loofe fpikes, each hanging downward, of a red colour below, and green at; the top. 6. The margaritifera, or pearl aloe, is a very beautiful plant. It is fmaller than mod of the aloe kind. The leaves are (hort, very thick, fharp pointed, and turning down, with a large thick end, appear there triangular. The colour of the leaves is a fine green, dripped in an elegant manner with white, and frequently tipped with red at the point* The flower-dalk, which rifes in the midd of the leaves, is round, fmooth, of a purple colour, and generally about eight inches high. When the plant has been properly cultivated, the flowers are dripped with green and white ; and fometimes they are entirely white. This aloe is Angular in not having the hitter refinous juice with which the leaves of mod others abound ; when a leaf of this fpecies .is cut, what runs from it is watery, . colourlefs, and perfeftly infipid. 7. The perfoliata, or focotorine aloe, hath long, narrow, fuccu- Jent leaves, which eome out without any order, and form large heads. The dalks grow three or four feet high; and have two, three, and fometimes four, of thefe heads branching out from it. The flowers grow in long fpikes, each danding on a pretty long footdalk ; they are of a bright red colour tipped with green, and generally appear in the winter feafon.. 8. The retufa, or cufliion aloe, hath very fhort, thick, fucculent leaves, comprefled on the upper fide like a cufliion. This grows very clofe to the ground ;. the flowers grow on flender dalks, and are of an herbaceous colour.. Culture. The proper earth for planting thefe veger tables in, is, one half frefli light earth from a com¬ mon, and the red an equal mixture of white fea-fand and fifted lime-rubbifli. This mixture (hould be al¬ ways made fix or eight months before the plants are to be fet in it. The common aloe will live in a dry green- houfe in winter; and may be placed in the open air in fummer, in a flickered fituation, but mud have very lit- tl'e water. Mod of the other aloes are bed preferved in an airy glafs-cafe, in which there is a dove, to make Aide* a little fire in very bad weather., The tendered kinds '* require a greater (hare of heat to preferve them in win¬ ter, and fliQuld be kept in a good dove, in a degree of heat ten degrees above temperate. Many other kinds may alfo be kept in-this heat; but the greater the heat, the- more water they always-require. About the beginning of June,, it is ufual in England to fet the pots-of aloes out of the houfe : but they fliould be fet under the (belter of hedges or trees; to keep them front the violence of the fun ; the rains alfo, which ufually fall in this and the following month, are apt to rob them* It ia therefore bed to keep them under cover the greated part of the year. The bed time to fliift thefe plants is the middle of July. They are, on this occafion, to be taken out of the pots, the loofe earth- to be picked from about their roots, and the decayed' or mouldy parts of them cut off; then a few dones are to be put at the bottom of the pot, and it is to be filled with the compofition before deferibed, and the plants carefully put in, the roots being fo difpofed as not to interfere with one another. They are to be carefully watered after this, at times, for three weeks, and fet in a fliady place. The common kind will bear the open air from May to October, and (hould be ftiif- ted every year. All the aloes are propagated by off-- fets, or by planting the leaves.. The off-fets fliould be taken from the mother plant, at the time when it is drifted: they are to be planted in very fmall pots of the proper mixed earth; and if that part of then* which joined to the mother-plant be obferved to be mold when taken off, it (hould lie on the ground in a (hady place two or three days before it is planted, o» therwife it will rot. After planting thefe, they (hould remain in a fliady place a fortnight; and then be re¬ moved to a very moderate hot-bed, plunging the pots. therein, which will help their driking new roots. To¬ wards the end of Augud they mud be, by degrees, hardened to the open air, by taking off the glaffes of the hot-bed; and in September they may be removed into the green-houfe. Properties, &c. The aloe is a kind of fymbolid plant to the Mahometants, efpecially in Egypt, and in fome meafure dedicated to the offices of religion ; for whoever returns from a pilgrimage to Mecca,, hangs it over his dreet-door, as a token of his ha¬ ving performed that holy journey. The fuperditious Egyptians believe that this plant hinders evil fpirits and apparitions from entering the houfe ; and on this account, whoever walks the dreets in Cairo, will find it over the doors both of Chridians and Jews. Front the fame plant the Egyptians diflil a water, which is fold in the apothecaries (hops at Cairo,.and recommen-- ded in coughs, hyderics, and adhmas.. An unexpe¬ rienced French furgeon, fays Haffelquid, gave a Cop- tite, 40 years old, afflicted with the jaundice, four tea¬ cups full of the diddled water of this fpecies of aloe, and cured him in four days.. This remedy, unknown to our apothecaries, is not difficult to be obtained, as the plant might eafily be raifed in the warm fouthern parts of Europe. The Arabians call it fittara. Of the leaves of the Guinea aloe, mentioned by Mr Adanfon in his voyage to Senegal, the negroes make very good ropes, not apt to rot in the water. Dr Sloane mentions two forts of aloe; one of which is A L O [ 4S5 ] A L O rs ufed for fifhing-lines, bow-ftrings, ftockings, and hammocks; the other has leaves which, like thofe of the wild-pine and banana, hold rain-water, and there¬ by afford a very neceffary refrefhment to travellers in hot countries, where there is generally a fcarcity of wells and water. In Mexico, the maguei, a fpecies of aloe, yields almolt every thing neceffary to the life of the poor. Befides making excellent hedges for their fields, its trunk ferved in place of beams for the roofs of their houfes, and its leaves inftead of tiles. From thofe leaves they obtained paper, thread, needles, clothing, fhoes, and ftockings,. and cordage; and from its co¬ pious juice they made wine, honey, fugar, and vine¬ gar. Of the trunk, and thickeft part of the leaves, when well baked, they made a very tolerable difh of food. Laftly, it was a powerful medicine in feveral dif- orders, and particularly in thofe of the urine. It is alfo at prefent one of the plants the moft valued and moft profitable to. the Spaniards.. The medical fubftance known by the name of aloes is the infpiffated juice of fome of the abovementioned fpecies. The ancients diftinguilhed two forts of aloes: the one was pure and of a yellowifh colour, inclining to red, refembling the colour of a liver, and thence na¬ med hepatic; the. other was full of impurities, and hence fuppofed to be only the drofs of the better kind. At prefent, various forts are met with in the fhops; which are diftinguifhed either from the places, from the fpecies of the plants, or from fome difference in the juices themfelves. Thefe may be all ranged in three claffes w 1. Alou Perfoliata, focotorine aloes, brought from the ifland Socotora in the Indian ocean, wrapt in lltins; it is obtained from the 15th fpecies abovementioned.— This fort is the pureft of the three : it is of a gloffy furface, clear, and in fome degree pellucid; in the lump, of a yellowilh red colour, with a purple call; when reduced to powder, of a bright golden colour. It is hard and friable in the winter, fomewhat pliable in fummer,. and grows foft betwixt the fingers. Its tafte is bitter, accompanied with an aromatic flavour, but infufficient to prevent its being difagreeable : the fmell is not very unpleafant, and fomewhat refembles that of myrrh. 2. A lor Hepatica, hepatic, Barbadoes, or common aloes (the juice of a variety of the former), is not fo clear and bright as the foregoing fort; it is alfo of a darker colour, more compaft texture, and for the moft part drier. Its fmell is much ftronger and more difagree¬ able ; the tafte intenfely bitter and naufeous, with lit¬ tle or nothing of the fine aromatic flavour of the focor torine.—The beft hepatic aloes come from Barbadoes in large gourd-fhells; an inferior fort of it (which is ge¬ nerally foft and clammy) is brought over in calks. Of the cultivation and preparation of hepatic aloes in the ifland of Barbadoes, we have the following ac¬ count in the London Medical Journal*. “ The lands in the vicinity of the fea, that is, from tv/o to three miles, which are rather fubjeftto drought than other- wife, and are fo ftony and lhallow as not to admit of the planting of fugar canes with any profpeft of fuc- cefs, are generally found, to anfwer beft for the aloe plant. The Hones, at leaft the larger ones, are firft picked up, and either packed in heaps, upon the moft lhallow barren fpots, or laid round the field as a dry Aloe.' wall. The land is then lightly ploughed, and very carefully cleared of all noxious weeds, lined at one foot dillance from row to row, and the young plants fet, like cabbages, at about five or fix inches from each o- ther. This regular mode of lining and fetting the plants is pra&ifed only by the moft exaft planters, in order to facilitate the weeding of theni, by hand, very frequently; beeaufe, if they are not kept perfectly clean and free from weeds, the produce will be but very fmall. They will bear being planted in any fea- fon of the year, even in the drieft, as they will live on the furface of the earth for many weeks without a drop of. rain. The moft general time,, however, of planting them, is from April to June. “ In the March following, the labourers carry a parcel of tubs and jars into the field, and each takes a flip or breadth of it, and begins by laying hold of a bunch of the blades, as much as he can conveniently grafp with one hand, while with the other he cuts it juft above the furface of the earth, as quickly as poffi- ble (that the juice may not be wafted), and then pla¬ ces the blades in the tub, bunch by bunch, or handful by handful. When the firft tub is thus packed quite full, a fecond is begun (each labourer having two); and by the time .the fecond is filled, all the juice is generally drained out of the blades in the firft tub. The blades are then lightly taken out, and thrown o- ver the land by way of manure and the juice is pour- ' ed out into a jar. The tub is then filled again with blades, and fo alternately till the labourer has produ¬ ced his jar full, or about four gallons and an half of juice, which is often done in fix or feven hours, and he has then the remainder of the day to himfelf, it being his employer’s intereft to get each day’s operation as quickly done as poffible.—It may be obferved, that al¬ though aloes are often cut in nine, ten, or twelve months after being planted, they are not in perfedtion till the fecond and third year; and that they will be productive for a length of time, fay 10 or 12 years, or even for a much longer time, if good dung, or mar nure of any kind, is ftrewed over the field once in three or four years, or oftener if convenient^ “ The aloe juice will keep for feveral weeks without injury. It is therefore not boiled .till a fufficient quan¬ tity is procured to make it an objedt for the boiling,- houfe. In the large wayj three boilers, either of iron or of copper, are placed to one fire, .though fome have but two, and the fmall planters only one. The boilers are filled with the juice ; and, as it ripens or becomes more infpiffated, by a conftant but regular fire, it is ladled forward from boiler to boiler, and frelh juice is added to that fartheft from the fire, till the juice in that neareft to the fire (by much the; fmalleft of the three, and commonly called by the name of latch, as in the manufactory of firtar) becomes of a proper eon- fiftency to be flapped or ladled out into gourds, or o- ther fmall veffels, ufed for its final reception. The proper time to fkip or ladle it out of the tatch, is when it is arrived at what is termed a refin height, or when it cuts freely, or in thin flakes, from the edges of a fmall wooden flice, that is dipped from time to time into the tatch. for that purpofe. A little lime-water is ufed by fome .aloe-boilers, during the procefs, when the ebulH= tion is too great. “•As* Aloe.

At this period the liquor is thrown through a ftrainer into a •deep vat, narrow at bottom, to cool, and to depofite its feculent parts.

The Mexicans, too, had made fome rude attempts of the fame kind ; but with lefs fuccefs than the Chinefe. We know alfo, that hieroglyphics were in ufe among the Egyptians pofterior to the praftice of alphabetical writing by the Jews; but whether the epiftelography, as it is called, of the former people, which was in vogue during the continuance of the hieroglyphics, might not pofiibly be another name for alphabetical writing, cannot be decided. 4. We fliall confider the argument on which the commonly received fuppofition entirely depends: that is, the natural gradation through the feveral fpecies of fymbols acknowledged to have been in ufe with various people, terminating at laft by an eafy tranfition, in the deteftion of alphabetical characters. The ftrength of this argument will be belt underltood from the fol¬ lowing reprefentation. “ 1. The firll method of embodying ideas would be by drawing a reprefentation of the objeCts them- felves. The imperfection of this method is very ob¬ vious, both on account of its tedioufnefs and its ina¬ bility of going beyond external appearances to the abftraCt ideas of the mind. “ 2. The next method would be fomewhat more general, and would fubllitute two or three principal circumltances for the whole tranfaCtion. So two kings, for example, engaging each other with military wea¬ pons, might ferve to convey the idea of a war between the two nations. This abbreviated method would be more expeditious than the former; but what it gained in concifenefs would be loft in perfpicuity. It is a defcription more compendious indeed, but ftill a de- fcription of outward objeCts alone, by drawing their refemblance. To this head may be referred the pic¬ ture-writing of the Mexicans. “ 3. The next advance would be to the ufe of fym¬ bols : the incorporation, as it were, of abftraCt and complex ideas in figures more or lefs generalized, in proportion to the improvement of it. Thus, in the earlier ftages of this device, a circle might ferve to ex- prefs the fun, a femicircie the moon ; which is only a contraction of the foregoing method. This fymbol- writing in its advanced ftate would become more re¬ fined, but enigmatical and myfterious in proportion to its'refinement. Hence it would become lefs fit for common ufe; and therefore more particularly appro¬ priated to the myfteries of philofophy and religion. Thus, two feet Handing upon water ferved to exprefs an impoffibility ; a ferpent denoted the oblique trajectories Of the heavenly bodies ; and the beetle, on account of fome fuppofed properties of that infeCt, ferved to re- prefent the fun. The Egyptian hieroglyphics were of this kind. “ 4. This method being ftill too fubtile and com¬ plicated for common ufe, the only plan to be purfued was a reduction of the firft ftage of the preceding method. Thus a dot, inftead of a circle, might Hand for the fun ; and a fimilar abbreviation might be extended to all the fymbols. On this fcheme every objeCt and idea would have its appropriated mark : thefe marks therefore would have a multiplicity pro¬ portionable to the works of nature and the operations of the mind. This method was likewife pfaCtifed by the Egyptians 5 but has been carried to greater per- Vol. L Part II. feCtion by the Chinefe. The vocabulary of the latter Alphabet, is therefore infinite, or at leaft capable of being ex- ■v'—-' tended to any imaginable length. But if we compare this tedious and aukward contrivance with the aftonifti- ing brevity and perfpicuity of alphabetical writing, we muft be perfuaded that no two things can be more diffimilar; and that the tranfition from a fcheme con- ftantly enlarging itfelf, and growing daily more intri¬ cate, to the expreffion of every poffible idea by the modified arrangement of four-and-twenty marks, is not fo very eafy and perceptible as fome have imagined. Indeed this feems ftill to be rather an expreffion of things in a manner fimilar to the fecond ftage of fym- bol-writing than the notification of ideas by arbitrary figns.” _ _ * To all this we fhall fubjoin the following remarks. Additional which feem to give additional force to the foregoing remarks in reafoning. tionoTthefe “ 1. Pliny afferts the ufe of letters to have been eter- arguments, nal; which {hows the antiquity of the praCtice to ex¬ tend beyond the asra of authentic hiftory. “ 2. The cabaliftical doftors of the Jews maintain, that alphabetical writing was one of the ten things which God created on the evening of the Sabbath. “ 3. Moft of the profane authors of antiquity aferibe the firft ufe of alphabetical characters to the Egyptians ; who, according to fome, received them from Mer¬ cury ; and, according to others, from their god Tenth. “ 4. There is very little reafori to fuppofe that even language itfelf is the effeCt of human ingenuity and invention.^ ^ Thus we have ftated the arguments in favour of the Anfwers to revelation of alphabetical writing ; which are anfwer-the above ed, by thofe who take the contrary fide, in the fol- ar2umcnts’ lowing manner. 1. Mofes no where fays that the alphabet was a newr thing in his time ; nor does he give the leaft hint of his being the inventor of it. The firft mention we find of •writing is in the x 7th chapter of Exodus ; where Mofes is commanded to •write in a book ; and which took place before the arrival of the Ifraelites at Sinai. This {hows that writing did not com¬ mence with the delivery of the two tables of the law, as fome have fuppofed. Neither are we to conclude that the invention had taken place only a fuort time before ; for- the •writing in a book is com¬ manded as a thing commonly underftood, and with which Mofes was well acquainted. It is plain, from the command to engrave the names of the twelve tribes of Ifrael upon Hones' like the engravings of a fignety that writing had been known and prattifed among them, as well as other nations, long before. We muft alfo remember, that the people were commanded to write the law on their dqor-pofts, &c. fo that the art ’ feems not only to have been known, but univerfally praClifed among them. But had writing been a new difeovery in the time of Mofes, he would probably have commemorated it as well as the other inventions of mufic, &c.: Nor is there any reafon to fuppofe that God was the immediate revealer of the art; for Mofes would never have omitted to record a circum- ftance of fuch importance, as the memory of it would have been one of the ftrongeft barriers againft ido¬ latry. 3 Again, ALP E 490 1 ALP Alphabet Again, though feveral profane writers attribute the The former was called the curiolsgic, the latter the tro- Alphabet.: origin of letters to the gods, or to fome divine perfon, ftcal hieroglyphic ; which lail was a gradual improve- v-"*J Claim of the Egyp¬ tians to the invention of letters. yet this is no proof of its being actually revealed ; but only that the original inventor was unknown. The learned bifhop of Gloucefter obferves, that the ancients gave nothing to the gods of whofe original they had any records ; but where the memory of the invention was loft, as of feed-corn, wine, writing, civil fociety, &c. the gods feized the property, by that kind of right which gives ftrays to the lord of the manor. As neither tire facred nor profane hiftorians, there¬ fore, have determined any thing concerning the in¬ vention of letters, we are at liberty to form what con- je&ures we think moft plaufrble concerning the origin of them; and this, it is thought, might have taken place in the following manner. “ 1. Men, in their rude uncultivated ftate, would have neither leifure, inclination, nor inducement, to cultivate the powers of the mind to a degree fufficient for the formation of an alphabet: but when a people arrived at fuch a pitch of civilization as required them to reprefent the conceptions of the mind which have no corporeal forms, neceffity would occafion further exertions, and urge them to find out a more expedi¬ tious manner of tranfa&ing their bufinefs than by pic¬ ture-writing. “ 2. Thefe exertions would take place whenever a nation began to improve in arts, manufactures, and commerce ; and the greater genius fuch a nation had, the more improvements would be made in the notation of their language ; whilft thofe people who had made lefs progrefs in civilization and fcience, would have a lefs perfeft fyftem of elementary characters ; and per¬ haps advance no farther for many ages than the marks or characters of the Chinefe. Hence we may fee, that the bufinefs of princes, as well as the manufac¬ tures and commerce of each country, would produce the neceffity of deviling fome expeditious manner of communicating information to one another.” The art of writing, -however, is of fo great anti¬ quity, and the early hiftory of moft nations fo full of fable, that it muft be extremely difficult to determine what nation or people may juftly claim the honour of the invention. But as it is probable that letters were the produce of a certain degree of civilization among mankind, we muft therefore have recourfe to the hifto¬ ry of thofe nations who feem to have been firft civi¬ lized. The Egyptians have an undoubted title to a very early civilization; and many learned men have attributed. the invention of letters to them. The late bilhop of Gloucefter contends, that Egypt was the parent of all the learning of Greece, and was reforted to by all the Grecian legiflators, naturalifts, and philofophers ; and endeavours to prove that it was one of the firft civilized countries on the globe. Their writing was of four kinds: 1. Hieroglyphic; 2. Symbolic; 3. Epijlolic; and, 4. Hierograrnmatic, In the moft early, ages they wrote like all other infant nations, by pictures; of which fome traces yet remain amongtt the hierogly¬ phics of Horapollo, who informs us, that theyrepre- fented fuller by a man’s two feet in water ; fire, by fmoke afeending, &c. But to render this rude Inven¬ tion lefs incommodious,, they foon devifed the method of putting one thing of limilar qualities for another. ment on the former. Thefe alterations in the manner of delineating hieroglyphic figures produced and per¬ fected another character, called the running-hand of the hieroglyphics, refembling the Chinefe writing ; which having been firft formed by the outlines of each figure, became at length a kind of marks ; the natural effeCts of which were, that the conftant ufe of them would take off the attention from the fymbol and fix it on the thing fignified. Thus the ftudy of fymbolic wri¬ ting would be much abbreviated ; becaufe the writer or decypherer would have then little to do but to ret member the power of the fymbolic mark; whereas before, the properties of the thing or animal delineated were to be learned. This, together with the other marks by in- ftitution, to denote mental conceptions, would reduce the characters to a fimilar ftate with the prefent Chi¬ nefe ; and thefe were properly what the ancients called hieroglyphieal. We are informed by Dr Robert Hun¬ tingdon, in his account of the Porphyry pillars, that there are fome ancient monuments of this kind yet re¬ maining in Egypt.. The facred book or ritual of the Egyptians, ac¬ cording to Apuleius, was written partly in fymbolic and partly in thefe hieroglyphic characters, in the fol¬ lowing manner: He (the hierophant) drew out cer¬ tain books from the fecret repeiitories of the fanCtu- ary, written in unknown characters, which contained the words of the facred formula compendioufly ex- preffed, partly by figures of animals, and partly by certain marks or notes, intricately knotted, revolving in the manner of a wheel, crowded together, and curled- inward like the tendrils of a vine, fo as to hide the meaning from the curiofity of the profane,” $ But though letters were of great antiquity in Egypt,d-erUr^ there is reafon to believe that they were not firft in-gVeri|e vented in that country. Mr Jackfon, in his Chrono-. ^ logical Antiquities, has endeavoured to prove, that they- were not invented or carried into Egypt by Taaut or Tboth, the firft Hermes, and fon of Mifraim, who lived about 500 years after the deluge ; but that they were in¬ troduced into that country by the fecond Hermes, who livedabout 40a years after theformer. This fecond Her¬ mes, according to Diodorus, was the inventor of gram¬ mar and mufic, and added many words to the Egyp¬ tian language. According to tl^e fame author alfo, he invented letters, rythm, and the harmony of founds. This was the Hermes fo much celebrated by the Greeks, who knew no other than hitnfelf. On the- other hand, Mr Wife afferts that Mofes and. Cadmus could not - learn the alphabet in Egypt; and that, the. Egyptians had no alphabet in their time. He adduces feveral reafons to prove that they had none till they received what is called the Coptic, which was introdu¬ ced either in the time of the Ptolemies or under P:am-; mitichus or Amafis; and the oldeft alphabetic letters which can be produced as Egyptian, appear plainly to have been derived from the Greek. Herodotus con- feffes, that all he relates before the reign of Pfammiti- chus is uncertain; and that he reports the early tranf- aftions of that natron on the credit of the Egyptian priefts, on which he did not greatly depend ; -and Dio¬ dorus Siculus is faid to have been greatly impofed upon by them. Manetho, the oldeft Egyptian hillorian, tranflated (Alphabet. 6 Claim of the Phoe; i- nicians.

He al¬ lows the Egyptian gods to have been mortal men ; but his hiilory was very much corrupted by the Greeks, and hath been called in queftion by feveral writers from the account which he himfelf gave of it. After Cam- byfes had carried away the Egyptian records, the priefts, to fupply their lofs, and to keep up their pre- tenfions to antiquity, began to write new records; wherein they not only unavoidably made great mi flakes, but added much of their own invention, efpecially as to diflant times. The Phoenicians have likewife been fuppofed the ' inventors of letters ; and we have the ftrongeil proofs of the early civilization of this people. Their mofl ancient hiflorian, Sanchoniatho, lived in the time»of Abibalus, father of Hiram king, of Tyre. He informs us, that letters were invented by Taaut who lived in Phoenicia in the 12th and 13th generations after the creation. “ Mifor (fays he) was the fon of Hamyn ; ffie fon of Mifor was Taci t, who invented the firfl letters for writing.” The Egyptians call him Thoth ; the Alexandrians Thcyth; and the Greeks Hermes, or Mercury. In the time of^ this Taaut or Mercury (the grandfon of Ham the fon of Noah), Phoenicia and the adjacent country was governed by Uranus, and after him by his fon Saturn or Cronus. He in¬ vented letters either in the reign of Uranus or Cronus ; and flaid in Phoenicia with Cronus till the 32d year of his reign. Cronus, after the death of his father Ura¬ nus, made feveral fettlements of his family, and tra¬ velled into other parts ; and when he came to the fouth country, he gave all Egypt to the god Taautus, that it fliould be his kingdom. Satichoniatho began his hillory with the creation, and ended it with placing Taautus on the throne of Egypt. He does not men¬ tion the deluge, but makes two more generations in Cain’s line from Protagonus to Agrovenus (or from Adam to Noah) than Mofes. As Sanchoniatho has not told us whether Taaut invented letters either in the reign of Uranus or Cronus, “ we cannot err much (fays Mr Jackfon) if we place his invention of them 550 years after the flood, or 20 years after thedifper- fion, and 2619 years before the Chriftian aera, and fix, or perhaps ten years, before he went into Egypt.” This prince and his pofterity reigned at Thebes in Upper Egypt for 15 generations. Several Roman authors attribute the invention of letters to the Phoenicians. Pliny fays (a), the Phoeni¬ cians were famed for the invention of letters, as well as for aftronomical obfervations and novel and martial arts. Curtius informs us, that the Tyrian nation are related to be the firfl who either taught or learned let¬ ters ; and Lucan fays, that they were the firfl who at¬ tempted to exprefs founds or words by letters. Eu- febius alfo tells us from Porphyry, that “ Sanchonia¬ tho fludied with great application the writings of Taaut, knowing that he was the firll who invented letters.” years after the Mezrite Taaut or Hermes. This fe¬ cond Hermes is called by Plato Theuth, and counfellor or facred fcribe to king Thanius; but it is not faid that he ever reigned in Egypt: but the former Taaut, or Athothes, as Monetho calls him, was the immedi¬ ate fucceffor of Menes the firfl king of Egypt. This fecond Mercury, if we may believe Manetho, compo- fed feveral books of the Egyptian hiftory; and having improved both the language and letters of that nation, the Egyptians attributed the arts and inventions of the former to the latter. The Phoenician language is ge¬ nerally allowed to have been a dialeft of the Hebrew; and tho’ their alphabet does not entirely agree with the Samaritan, yet there is a great fimilarity between them. Aftronomy and arithmetic were much cultivated among them in the-mofl early ages; their fine linen, purple, and glafs, were much fuperior to thofe of other na¬ tions ; and their extraordinary Ikill in architedture and other arts was fuch, that whatever was great, elegant, or pleafing, whether in buildings, apparel, or toys, was diflinguifhed by the epithet of Tyrian or Sidonian; thefe being the chief cities of Phoenicia. Their great proficiency in learning and arts of all kinds, together with their engrofling all the commerce of the weftern world, are likewife thought to give them a juft, claim to the invention of letters. 7 The Chaldeans alfo have laid claim to the invention Of the of letters; and with regard to this, there is a tradition c^a^eans< among the Jews, Indians, and Arabians, that the E- gyptians derived their knowledge from Abraham, who was a Chaldean. This tradition is in fame degree confirmed by moft of the weftern writers, who afcribe the inventions of arithmetic and aftronomy to the Chaldeans. Jofephus pofitively afferts, that the Egyp¬ tians were ignorant of the fciences of arithmetic and aftronomy before they were inftrudled by Abraham ; and Sir Ifaac Newton admits, that letters were*known in the line of that patriarch for many centuries before Mofes. The Chaldaic letters appear to have been de¬ rived from the Hebrew or Samaritan ; which are the fame, or nearly fo, with the old Phoenician. Ezra is fuppofed to have exchanged the old Hebrew characters for the more beautiful and commodious Chaldee, which are fill in ufe. Berofus, the moft ancient Chaldean hiftorian, who was born in the minority of Alexander the Great, does not fay that he believed his country¬ men to have been the inventors of letters. 8 The Syrians have alfo laid claim to the invention of the letters. It is certain, indeed, that they yielded tonans* no nation in knowledge and fkill in the fine arts. Their language is faid to have been the vernacular of all the oriental tongues, and was divided into three diale&s. 1. The Aramean, ufed in Mefopotamia, and by the inhabitants of Roha and Edefa of Harram, and the Outer Syria. 2. The dialed of Paleftine ; fpoken by the inhabitants of Damafcus, Mount Libanus, and the Inner Syria. 3. The Chaldee or Nabathean dia¬ led, the moft unpolifhed of the three ; and fpoken in the mountainous parts of Affyria, and the villages of 3 0^2 Irac (a) See above, nR 2. where he fays that the knowledge of letters was eternal. What dependence can we put in the teftimony of .fuch a writer ? 4 ALP [ 492 ] ALP Alphabet. Irac or Babylonia. It lias been generally believed, that no nation of equal antiquityhad a more confiderable trade than the Syrians : they are fuppofed to have firft brought the commodities of Perfia and India into the weft of Afia ; and they feem to have carried on an inland trade by engroffing the navigation of the Eu¬ phrates, whilft the Phoenicians traded to the moft di- itant countries. Notwithftanding thefe circumftances, however, which might feem to favour the claim of the Syrians, the oldeft charadlers they have are but about three centuries before Chrift. Their letters are of two forts. 1. The Eftrangelo, which is the more ancient; and, 2. The Fftiito, the iimple or common character, 9 which is the more expeditious and beautiful. Of the In- We muft next examine the claims of the Indians, dians. whofe pretenfions to antiquity yield to no other nation on earth. Mr Halhed, who has written a grammar of the Shanfcrit language, informs us, that it is not only the grand fource of Indian literature, but the parent of almoft every dialed! from the Perfian gulph to the Chinefe feas, and which is faid to be a language of the moft venerable antiquity. At prefent it is appropri¬ ated to religious records of the Bramins, and there¬ fore fhut up in their libraries; but formerly it appears to have been current over the greateft part of the eaftern world, as traces of* its extent may be found in almoft every diitrict of Afia. Mr Halhed informs us, that “ there is a great fimi- larity between the Shanfcrit words and thofe of the Perfian and Arabic, and even of Latin and Greek; and thefe not in technical or metaphorical terms, but in the main ground-works of language ; in monofylla- bles, the names of numbers, and the appellations of fuch things as would be firft difcriminated on the im¬ mediate dawn of civilization. The refemblance which may be feen of the chara&ers on the medals and fignets of different parts of Afia, the light they reciprocally throw upon one another, and the general analogy which they all bear to the grand prototype, affords another ample field for curiofity. The coins of Affam, Na- paul, Calhmiria, and many other kingdoms, are all ftamped with Shanfcrit letters, and moftly contain al- lufions to the old Shanfcrit mythology. The fame con¬ formity may be obferved in the impreffions of feals from Bootan and Thibet.” The country between the Indus and Ganges ftill preferves the Shanfcrit language in its original purity, and offers a great number of books to the perufal of the curious ; many of which have been handed down from the earlieft periods of human civilization. There are feven different forts of Indian hand-wri¬ tings, all comprifed under the general term of Naagoree, vyhich may be interpreted ‘writing. The Bramins fay that letters were of divine original; and the elegant Shanfcrit is ftyfed Daeb-naagoree, or the writings of the Immortals, which might not improbably be a re¬ finement from the more fimple Naagoree of former ages. The Bengal letters are another branch of the fame ftock. The Bramins of .Bengal have all their Shanfcrit books copied in their national alphabet, and they tranfpofe into them all the Daeb-naagbree manu- fcripts for their own perufal. The Moorifh dialed is that fpecies of Hindoftauic which we owe to the con- quefts of the Mahometans. The Shanfcrit language contains about 700 radical words; the fundamental part being being divided into Alphabet, three claffes, viz. 1. Dbaat, or roots of verbs; 2. Shubd, or original nouns; 3. Evya, or particles. Their al¬ phabet contains 50 letters ; viz. 34 confonants and 16 vowels. They affert that they were in poffeffion of letters before any other nation in the world; and Mr Halhed conjectures, that the long-boafted original ci¬ vilization of the Egyptians may ftill be a matter of dif- pute. The Rajah of Kilhinagur affirms, that he has in his poffeffion Shanfcrit books, where the Egyptians are conftantly defcribed as.difciples, not as inftruftors; and as feeking in Hindoftan that liberal education, and thofe feiences, which none of their own countrymen had fufficient knowledge to impart. Mr Halhed hints alfo, that the learning of Hindoftan might have been tranfplanted into Egypt, and thus have become fami¬ liar to Mofes. Several authors, however, are of opi- nioo, that the ancient Egyptians poffeffed themfelve* of the trade of the Eaft by the Red Sea, and that they carried on a confiderable traffic with the Indian na¬ tions before the time of Sefoftris; whom they fuppofe to have been cotemporary with Abraham, though Sir Ifaac Newton conjeftures him to have been the Shifhak who took Jerufalem in the time of Rehoboam. In the year 1769, one of the facred books of the Gentoos called Bagavadam, tranflated by Meridas Poule, a learned man of Indian origin, and chief in¬ terpreter to the fupreme council of Pondicherry, was fent by him to M. Bertin in France. In his preface he fays, that it was compofed by Viaffer the fon of Brahma, and is of facred authority among the worfhip- pers of Vifchnow. This book claims an antiquity «f 5000 years ; but M. de Guines has ffiown, that its pre¬ tenfions to fuch extravagant antiquity are entirely in- conclufive and unfatisfaftory: whence we may con¬ clude, fays Mr Aftle, that though a farther inquiry in¬ to the literature of the Indian nations may be laudable, yet we muft by no means give too eafy credit to their relations concerning the high antiquity of their manu- fcripts and early civilization. 10 It is not pretended that the Perfians had any great Letters not learning among them till the time of Hyftafpes the ‘a father of Darius. The former, we are told, travelled er a * into India, and was inftrudted by the Bramihs in the feiences for which they were famed at that time. The ancient Perfians defpifed riches and commerce, nor had they any money among them till after the conqueft of Lydia. It appears by feveral inferipfions taken from the ruins of the palace of Perfepolis, which was built near 700 years before the Chriftian xra, that the Per¬ fians fometimes wrote in perpendicular columns like the Chinefe. This mode of writing was firft made ufe of on the items of trees, pillars, or obeliiks. As for thofe fimple characters found on the weft fide of the ftair-cafe of Perfepolis, fome have fuppofed them to be alphabetic, fome hieroglyphic, and others antediluvian. Dr Hyde pronounces them to have been mere whim- fical ornaments, though the author of Conjectural Ob- fervations on Alphabetic Writing fuppofes them to be fragments of Egyptian antiquity brought by Cambyfes from the fpoils of Thebes. The learned are generally agreed, that the Perfians were later in civilization than many of their neighbours; and they are not fuppofed to have any pretenfions to the invention of letters. As the Arabians have been in poffeffion of the coun¬ try Mphabet. try they now inhabit for upwards of 3700 years, with¬ out being intermixed with foreign nations, or fubjuga- ted by any other power, their language muft be very ancient. The two principal dialers of it were that fpoken by the Hamyarites and other genuine Arabs ; and that of the Koreifh, in which Mahomet wrote the Alcoran. The former is named by oriental writers for by the trabians. ALP C 493 ] ALP their calculations ; and we have fhown, that thefe were Alphabet, the parents of letters. This circumliance greatly fa- vours their claim to the invention; becaufe Chaldea, and the countries adjacent, are allowed by all authors, both facred and profane, to have been peopled before Egypt; and it is certain that many nations faid to be defcended from Shem and Japhet, had their let- the Arabic of Hamyar; the latter, the pure, or defecated ters from the Phoenicians, who were defcended from Arabic.

Hence fome have fuppofed that the Ara¬ bians were the inventors of letters ; and Sir Ifaac New¬ ton is of opinion, that Mofes learned the alphabet from the Midianites, who were Arabians. The alphabet of the Arabs confifts of 28 letters li¬ the moft ancient commercial nation, it is very probable that they communicated letters to the Egyptians, the ports of Tyre and Sidon being not far diftant from each other. “ Mr Jackfon is evidently miftaken when he fays, that letters were invented 2619 years before the birth of Chrift. The deluge recorded by Mofes was 2349 milar to the ancient Cufic, in which the firft copies of years before that event; and if letters were not invent- the Alcoran were written. The prefent Arabic cha- rafters were formed by Ebn Moklah, a learned Ara¬ bian, who lived about 300 years after Mahomet. The Arabian writers themfelves inform us, that their alpha¬ bet is not very ancient, and that they received it only a Ihort time before the introduction of Iflamifm. On this account of the pretenfions of different" na¬ ed till 550 years after, as he afferts, we muft date their difcovery only 1799 years before the Chriftian sera, which is 410 years after the reign of -Menes the firft king of Egypt, who, according to Syncellus and others, is faid to have been the fame perfon with the Mifor of Sanchoniatho, the Mizraim of the Scriptures, and the Ofiris of the Egyptians; but whether this be tions to the invention of letters, Mr Aftle makes true or not, Egypt is frequently called in Scripture the the following reflections. “ The vanity of each na- land of Mizraim. tion induces them to pretend to the moft early civili¬ zation ; but fuch is the uncertainty of ancient hiftory, that it is difficult to determine to whom the honour is due. It Ihould feem, however, that the conteft may be confined to the Egyptians, the Phoenicians, and the Chaldeans. The Greek writers, and moft of thofe who have copied them, decide in favour of Egypt, be- This Mizraim, the fecond fon of Amyn or Ham, feated himfelf near the entrance of Egypt at Zoan, in the year before Chrift 2188, and 160 years after the flood.

The pofitive claim of the Phoenicians does not depend entirely upon the teftimony of Sanchonia¬ tho ; the credit of his hiftory is fo well fupported by Philo of Byblus his tranflator, Porphyry, Pliny, Cur- tius, Lucan, and other ancient writers, who might will not enable us to trace the knowledge of them; have feen his works entire, and whofe relations deferve at leaft as much credit as thofe of the Egyptian and Greek writers. It muft be allowed, that Sanchonia- tho’s hiftory contains many fabulous accounts; but though this want of materials is no proof that letters were not known until a century and an half after the; deluge. As for the pretenfions of the Indian nations, we muft be better acquainted with their records before does not the ancient hiftory of the Egyptians, the we can admit of their claim to the firft ufe of letters; Greeks, and moft other nations, abound with them to a much greater degree ? The fragments which we have of this moft ancient hiftorian are chiefly furniftied by Eufebius, who took all poffible advantages to re- prefent the Pagan writers in the worft light, and to render their theology abfurd and ridiculous. “ The Phoenician and Egyptian languages are very fimilar; but the latter is faid to be more large and full, which is an indication of its being of a later date. The efpecially as none of their manufcripts of any great antiquity have as yet appeared in Europe.

The writings, therefore, attributed to the antediluvians, muft appear quite uncertain ; though it might be improper to affert that letters were unknown before the deluge recorded by Mofes.” All the al- Our author proceeds to (how, that all the alpha- phahets in bets in the world cannot be derived from one origi- the world nal; becaufe there are a variety of alphabets ufed in 'roved to <^®erent Pairts °f Afia, which vary in name, number, arifeVrom order, and power, from the Phoenician, ancient Hebrew, or Samaritan. In feveral of thefe alphabets alfo, there are marks for founds peculiar to the lan¬ guage of the eaft, which are not necelfary to be em¬ ployed in the notation of the languages of Europe. None of the alphabets to the eaft of Perfia have any connexion with the Phoenician or its derivatives, ex¬ cept where the Arabic letters have been introduced by the conquefts of the Mahometans. The foundation of all the Indian chara&ers are thofe called Jhanfcrit, or fungfkrit. This fignifies fomething brought to perfec¬ tion, in contradiftin&ion to prakrit, which fignifies vulgar or unpolifhed. Hence the refined and religious language and charadters of India are called Sungfkrit, and the more vulgar mode of writing and expreffion Prakrit. From this Shanfcrit are derived the facred charafters of Thibet, the Cafhmirian, Bengalefe, Ma- labaric, and Tamoul; the Singalefe, Siamefe, Maharat- tan, Concanee, &c. From the fame fource we may derive the Tangutic or Tartar charadters, which are iimilar,in their great outlines, to the Shanfcrit; though it is not eafily determined which is derived from the other. The common Tartar is generally read, like the Chinefe, from top to bottom. There are, however, feveral alphabets ufed in diffe¬ rent parts of Afxa, entirely different not only from the Shanfcrit and all thofe derived from it, but alfo from the Phcenician and thofe which proceed from it. Some of thefe are the alphabet of Pegu, the Batta charadters ufed in the ifland of Sumatra, and the Barman or Bo- man charadters ufed in fome parts of Pegu. The names and powers of the letters of which thefe alpha¬ bets are compofed, differ entirely from the Phoenician, or thofe derived from them. It is impoffible to affimi- late their forms, and indeed it is by no means eafy to conceive how the 50 letters of the Shanfcrit language could be derived from the Phcenician alphabet, which confiftcd originally only of 13 ; though it is certain, that by far the greater number of alphabets now in ufe are derived from the ancient Hebrew, Phoenician, or Samaritan. Mr Aftle next proceeds to confider what alphabets are Alphabet, derived from the Phoenician. Thefe he fuppofes to have been immediately the ancient Hebrew or Samaritan ; Alp I^etg the Chaldaic ; the Baftulian (a) or Spanilh Phceni-der/eri cian ; the Punic, Carthaginian, or Sicilian; and the fro n the Pelafgian. From the ancient Hebrew proceeded the ^ 'lucian Chaidalc or fquare Hebrew; the round Hebrew ; and what is called the running band of the Rabbins. The Pelafgian gave birth to the Etrufcan, Eugubian, or Umbrian, Ofcan, Samnite, and Ionic Greek, written from the left. From the Chaldaic or fquare Hebrew are derived the Syriac, and the ancient and modern Arabic. The Syriac is divided into the Eftrangelo and Mendasan, and the modern Arabic has given rife to the Perfian and Turkifh. From the ancient Arabic are derived the Kufic or Oriental, the Mauritanic or Occidental; the African or Saracen, and the Moorifh. The Ionic Greek gave rife to the Arcadian, Latin, ancient Gaulifti, ancient Spanifh, ancient Gothic, Cop¬ tic, Ethiopic, Ruffian, Illynian or Sclavonic, Bulga¬ rian and Armenian. From the Roman are derived the Lombardic, Vifigothic, Saxon, G illican, Franco- Gallic or Merovingian, German, Caroline, Capetian, and modern Gothic. The Punic letters are alfo called Tyrian, and were much the fame with the Carthaginian or Sicilian.. The Pu¬ nic language was at firft the fame with the Phoenician; it is nearly allied to the Hebrew, and has an affinity with the Chaldee and Syriac. Some remains of it are to be met with in the Maltefe. To make a complete Punic, Carthaginian, or Sicilian alphabet, we muft admit feveral pure Phoenician letters. The Pelafgi were likewife of Phoenician original; and, according to Sanconiatho, the Diofcuri and Ca¬ bin wrote the firft annals of the Phoenician hiftory, by order of Taaut the inventor of letters. They made ffiips of burthen, and being caft upon the coaft near mount Cafius, about 40 miles from Pelufium, where they built a temple in the fecond generation after the deluge related by Mofes, they were called Pelafgi from their paffing by fea, and wandering from one coun¬ try to another. Herodotus informs us, that the Pe¬ lafgi were defcendants of the Phoenician Cabin-, and that the Samothracians received and prac'difed the Ca- biric myfteries from them. The Pelafgic alphabet pre¬ vailed in Greece till the time of Deucalion, when the Pelafgi were driven out of Theffaly or Oenotria by the Hellenes ; after which fome of them fettled at the mouth of the Po, and others at Croton, now Cartona in Tufcany. Their alphabet confifted of 16 letters, and the Tyrrhenian alphabet, brought into Italy before the reign of that prince, confifted of no more than 13. Deucalion is faid to have reigned about 820 years af¬ ter the deluge, and 1529 before the Chriftian sera. That the Tyrrheni, Tyrfeni, or Hetrufci, fettled in Italy long before this period, appears from the tefti- mony of Herodotus, who informs us, that a colony went by fea from Lydia into Italy under Tyrrhenus; and Dionyfius of Halicarnaffus proves that many au¬ thors called them Pelafgi. He then cites Hellanicus Lefbicus, an author fomewhat more ancient than He¬ rodotus, (a) The Baftuli are faid to have been a Canaanitifti or Phoenician people who fled from Joflrua, and fettled afterwards in Spgin. ALP C 495 1 ALP Alphabet, rodotus, to prove, that they were firft called Pelafgi Tyrrheni; and when they paffed into Italy, they fettled in that part of it called Etruria. Their emigration took place about the year of the world 2011, or 1993 years before the Chriftian sera, which is 350 years be¬ fore the Pelafgi left Greece. Bifhop Cumberland ad¬ duces many proofs to fhow that the Tyrrhenians origi¬ nally came out of Lydia into Italy. Several Roman authors alfo fpeak of this Lydian colony; and Horace compliments his patron Maecenas upon his Lydian de- fcent: Lydorum quicquid Etrufcos Incoluit fines, nemo generofior ejl te. The Etrufcan letters are Pelafgic, and feveral of the Etrufcan infcriptions are written in the Pelafgic lan¬ guage. The Roman letters are Ionic. The Ofcan language was a dialed of the Etrufcan ; their charac¬ ters are nearer the Ionic or Roman than the Etrufcan. There is alfo very little difference between the Pelaf- gian, Etrufcan-, and moft ancient Greek letters, which are placed from right to left. The Arcadians were an¬ cient Greeks, and ufed the Ionic letters ; .but at what time they began to write from left to right is not known, as their chronology is very uncertain. The E- trufean, Ofcan, and Samnite alphabets, are derived from the Pelafgic ; they; differ from each other more in name than in form, but a far greater number are derived from the Ionic Greek; namely, the Arcadian, the Latin or Roman, and the others already enumerated. The Ru¬ nic is immediately derived from the Gothic. According to Dionyfius of Halicarnaffus, the fir3; Greek colony , which came into Italy confifted of Ar¬ cadians under, the conduft of Oenotrus the fon of Ly- caon, and fifth in defeent from Phoroneus the firfl king of Argos, who reigned about 566 years before the taking of Troy, and x 750 years before the Chri¬ ftian asra. Thefe Oenotrians were called Abo>igir.es ; and after they had been engaged for many years in a war with the ^Siculi, entered into an alliance with a colony of the Pelafgi, who came out of Theffaly into Italy, after having been driven from the former coun¬ try.—About 1476 B. C. another colony of the Pelaf¬ gi, who had been driven out of Theffaly by the Cu- retes and Leleges, arrived in Italy, where they, affifted the Aborigines to drive out the Siculi; polfeffing them- felves of the greateft part of the country between the Tiber and the Liris, and building, feveral cities. So- linus and Pliny tell us, that the Pelafgi firft carried letters into Italy ; and the latter diftinguifhes between the Pelafgi and the Arcades : fo the letters firfl car¬ ried into Italy were not the Ionic Greek, but thofe more ancient Pelafgi characters which the Pelafgi car- ried with them before Deucalion and Cadmus are faid to have come into Bceotia and Theflaly. The ftory of Cadmus, is much involved in fable ; but it is agreed by moft of the ancients, that the children of Agenor, viz. Cadmus, Europa, Phoenix, and Cilix, carried wi h them a colony, compofed of Phoenicians and Sy¬ rians, into Afia Minor, Crete, Greece, and Lybia, where they introduced, letters, mufic, poetry, and other arts, fciences, and cuftoms, of the Phoenicians. Dionyfius enumerates the following Greek colonies which came into Italy: 1. The Aborigines under Oe¬ notrus from Arcadia. 2. The Pelafgic colony which came from Hoemoma or Theflaly. 3.^Another Arca¬ dian colony which came with Evander from Paiantium. Alphabet.^ 4. Thofe who came from Peloponnefus with Hercules; * and, 5. Thofe who came with CEneas from Troy. It is not eafy to difeover when the Ionic way of writing from left to right was introduced into Italy ; but it is cer¬ tain, that it did not univerfally prevail even in Greece till feveral ages after it was found but. The Athenians did not-comply with it till the year of Rome 350 ; nor was it pra&ifed by the Samnites even in the fixth century of that city, or 230 years before Chrift : for M. Gse- belin, Vol. VI, pi. 2.'gives us the Samnite alphabet of that century, wherein the letters are placed from right to left; although the Ionic way of writing prevailed in fome parts of Italy in the third century of Rome. u In time (fays Pliny), the tacit confent of all nations agreed to ufe the Ionic letters.5 The Romans confent- ed to this mode about the time of Tarquinius Prifcus their fifth king.” The letters brought by Damaratus the Corinthian, the father of Tarquin, Mr Wife thinks; mull have been the new or Ionic alphabet, and not the fame with that brought1 by Evander 500 years before. After the Romans had eftablifhed the ufe of the Ionic letters, they feem not to have acknowledged the Pe- l.'fgian and Etrufcan to have been Greek alphabets: the moft learned of them knew none.older than the I- onic, as appears from the Greek Farnefe infcriptions of Herodes Atticus. This learned man, out of a re¬ gard to antiquity, caufed the oldeft orthography to be obferved in the writing, and the letters to be deli¬ neated after the moft antique forms that could be found? and they are plainly no other than the Ionic or right-handed characters. The ancient Gaulifti letters are derived from theSee Plates Greek, and their writing approaches more nearly tb|^f^.X* the Gothic than that of the Romans : this appears by mens ^ithe the monumental infeription of Gordian, meffenger of ancient ak the Gauls, who fuffered martyrdom in the third cen- phabets tury with all his family. Thefe ancient Gaulifh c^a' mgrat "d ~ rafters were generally ufed by that people before themeraC conqueft of Gaul by Caefar; but - after* that time the Roman letters were gradually introduced. The ancient Spaniards ufed letters nearly Greek before their inter- courfe with the Romans. The ancient Gothic alpha¬ bet was- very fimiiar to the Greek, and is attributed to. - Ulphilas, bilhop of the Goths, who lived in Mtefia a- bout 370 years after Chrift. He tranflated the bible into the Gothic tongue. This circumftance might have occafioned the tradition of his having invented thefe letters; but it is probable that thefe charafters . were in ufe long before this time. The Runic alpha¬ bet is derived from the ancient Gothic. The Coptic letters are derived immediately from tlii Greek. Some have confounded them with the ancient Egyptian; but there is a very material difference be¬ tween them. The Ethiopic alphabet is derived from the Coptic. The alphabet proceeding from that of the Scythians eftablifhed in Europe, is the fame with what St Cyril calls the Servien. The Ruffian, Illyrian or Sclavonic, and the Bulgarian, are all derived from the Greek. The Armenian letters differ very much from the Greek, , from which they are- derived,, as well as from the Latin. 16 > With regard to the alphabets derived from the La-^f^eta tin, the Lombardic relates to the manuferipts of Italy1; tjje the Batin.: ALP the Vifigothic to thofe of Spain ; the Saxon to thofe of England; the Gallican and Franco-Gallic or Me¬ rovingian to the manufcripts of France; the German to-thofe of that country; and the Caroline, Copetian; and Modern Gothic, to all the countries of Europe who read Latin. The firft fix of thefe alphabets are before the age of Charlemagne, the laft three pofterior [ 49<5 1 ALP indeed nothing elfe than Latin writing degenerated. A'phaliet^ It began in the 12th century, and was in general ufe, » efpecially among monks and fchoolmen, in all parts of Europe, till the reftoration of arts in the 15th century, and continued longer in Germany and the northern na¬ tions. Our ftatute-books are Hill printed in Gothic letters. The moft barbarous writing of the feventh, to it. They are more diftinguiihed by their names eighth, and ninth centuries, was preferable to the mo- than the forms of their characters, and the former indicate all of them to have been of Roman extraction. Each nation, in adopting the letters of the Romans, added thereto a tafte and manner peculiar to itfelf, dern Gothic. It is diverfified in fuch a manner a fcarce admit of defcription; and the abbreviations ufed by the writers were fo numerous, that it became very difficult to read it; which was one of the great caufes which obvioufly dillinguiffied it from the writings of of the ignorance of thofe times. Along with tliisj all other people ; whence arofe the differences between the writings of the Lombards, Spaniards, French, Sax¬ ons, Germans, and Goths, and all the ftrange terms obfervable in the writings of the Francic Gauls or Me¬ rovingians ; and thofe of the Carlovingians their fuc- ceffors may be traced from the fame fource. From thefe diitinclions the name of national 'writing was de¬ rived. The writing of Italy was uniform till the irruption of the Goths, who disfigured it by their barbarous take. In 569, the Lombards, having poffeffed them- felves of all Italy, excepting Rome and Ravenna, in¬ troduced that form of writing which goes under their name ; and as the Popes ufed the Lombardic manner in their bulls, the name of Roman was fometimes gi¬ ven to it in the nth century; and though the domi¬ nion of the Lombards continued no longer than 206 years, the name of their writing continued in Italy from the 7th to the 13th century, and then ceafed; when learning, having declined in that as well as in o- ther countries, the manner of writing degenerated in¬ to the modern Gothic. The Vifigoths introduced their form of writing into Spain, after having over-run that country ; but it was aboliffied in a provincial fynod held at Leon in 1091, when the Latin characters were eftabliffied for all pub¬ lic inftruments, though the Vifigothic were ufed in private writings for three centuries afterwards. The Gauls, on being fubje&ed by the Romans, a- dopted their manner of writing; but by fubfequent additions of their own, their characters were changed into what is called the Gallican or Roman Gallic mode. This was changed by the Franks into the Franco-Gal¬ lic or Merovingian mode of writing, being praCtifed under the kings of the Merovingian race. It took place towards the clofe of the fixth century, and con¬ tinued till the beginning of the ninth. The German mode of wilting was improved by Charlemagne, and this improvement occafioned ano¬ ther diftinCtion in writing by introducing the alphabet named Caroline, which declined in the 12th century, and was fucceeded in the 13th by the modern Gothic. In France it had degenerated by the middle of the Ioth century, but was reftored in 987 by Hugh Ca¬ pet, whence it obtained the name of Capetian. It was ufed in England as well as Germany and France. The modem Gothic, which fpread itfelf all over Europe in the 12th and 13th centuries, is improperly named, as not deriving its origin from the writing an¬ ciently ufed by the Goths. It is, however, the worit and moft barbarous way of writing, and originated a- mong the fchoolmen in the decline of the arts; being N°i3. 5 however, the Lombardic, Gothic, Roman, Caroline, and Copetian modes of writing, were occafionally ufed by individuals. The idea that all the alphabets above mentioned are derived from the Roman, tends to prove the diftindtion of national writing, and is of great ufe in difcovering the age of manufcripts: for though we may not be •able exadtly to determine the time when a manufcript was written, we may be able nearly to afcertain its age. For example, if a writing is Morvingian, it may be declared not to be pofterior to the ninth, nor prior to the fifth, century. If another be Lombardic, it may be affirmed to be pofterior to the middle of the 6th, and prior to the 13th. Should it be Saxon, it cannot be of an earlier date than the 7 th, nor later than a- bout the middle of the 12th. I7 Having confidered whence the alphabets nowin ufe,Letters throughout the various nations of the world are derived, co“ld ^ot it remains to fay fomething concerning them as the ele- ments of words, or how far they are capable of ex- decompofi- preffing thofe founds, which, by proper combination tion of ian- and arrangement, eonftitute articulate language. The gua2e* number of Ample founds in any language cannot be very numerous; and it is plainly thefe fimple founds a- lone that wfe have occafion to reprefent by alphabetical characters. Hence the perfon who firft invented let¬ ters, muft have been capable of analyfing language in a manner which feems by no means eafy to do, and concerning which even the learned among ourfelves are not yet agreed. It is this difficulty which has pro¬ duced the great diverfity in the number of alphabetical characters ufed by different nations ; and where we fee a vaft number of them ufed, we may account the wri¬ ting not the better, but much the worfe for it; and whoever the pretended inventor was, it is more rea- fonable to fuppofe that he disfigured an alphabet al¬ ready invented, by unneceffary additions, than been the author of one himfelf. When we confider alphabetical charafters as thus re- Probably . fulting from an analyfis of language, it will by no means Je* appear probable that it was derived from a gradual and progreflive progreffive operation of the human mind through many evolution of ages. There is not the leaft affinity betwixt reprefent- the human ing any objeft by a picture and finding out the foundsPowers- which compofe the word by which it is expreffed ; nor, though a nation had been in ufe to reprefent things ei¬ ther in this method, or by any kind of arbitrary marks, for thoufands of years, could the one ever have led to the other. Arbitrary marks muft always be the fame with pictures in this refpeCt, that they muft always be fixed to particular objeCts, and thus be increafed ad infini¬ tum. Letters, on the other hand, are indifferent to all iS Alpha tie rim .1 inu ^ lL/'//ATTE VA t / Ar Tiq TTJSSJMA. r s/'.rf/Ye ttt/ '/tt/lt/tytt/t p*y//y//.^r~ " "ij' /'" " ■/ s/*- * t I’latr IX, 1 2 B "> 0 4 J) 3 E '/.' r) # A h1 s e: 4)L lOEJ 11 El 12 0 p P 14 Pv 1 > S |'!0 1' 1 Q Plwenuunn.

This might furnifh an argument of fome ftrength for the divine revelation of writing, were it not that other arts feemingly as ufeful, and as difficult to be in¬ vented, had not been exprefsly afcribed to particular perfons whom we cannot fuppofe to have been divinely infpired. Thus metallurgy, mulic, the keeping of cattle, and ufe of tents, are all afcribed to a fmgle fa¬ mily ; and though writing be not exprefsly mentioned as an invention in Scripture, there is no reafon to have recourfe to a revelation for it as long as the human fa¬ culties are known to have been fufficient for the inven¬ tion of it. Nevertheiefs, if we take a review of the different arts which mankind have invented, we fhall find, that few of them refulted from any gradual pro- grefs or evolution of the powers of the human mind, but rather by fome fudden and almoft unaccountable turn of thought in an individual. Thus, the art of printing, little inferior in its utility to that of writing, lay hid for ages, and was at laft invented we fcarce know how; fo that if one inclined to fuppofe this a divine revelation, he could be at little lofs for argu¬ ments to fupport his hypothefis. This was what all the inventions and evolutions of human powers fince the creation had never been able to accomplifli; yet ndbody believes that it required fupernatural abilities to be the author of this art, becaufe we fee plainly that it might have occurred to the human mind from various fources, and are furprifed that it did not occur long before. In like manner, the method of account¬ ing for the celeftial motions by the united forces of proje&ion and gravitation, was no refult of the pro- grefs that mankind had made In fcience, but luckily occurred to Mr Horrox, without any thing that we know to direct him, or perhaps from caufes alraoft un¬ known to himfelf. Thus alfo, the fteam-engine, aero- ilation, &c. were fuddenly invented only by a flight re¬ view of principles well known before, and which had been a thoufand times overlooked by thofe who might have invented both. Alphabetic writing, therefore, might have been no deduction from hieroglyphic or picture writing, from which it is erflentially different; and it feems to be fome confirmation of this, that all nations who ever pretended to the invention of letters, have afcribed it-to the labours of one particular per- fon, without taking notice of the progrefs made to¬ wards it in preceding ages. Of th quired the knowledge of them in three weeks, and cor- refponded with him therein during their intimacy. ALPHiENIX, white barley-fugar, to which is gi¬ ven an extraordinary name, to render it more valuable. This fugar, which is thought good for colds, is made of common fugar, which is boiled until it becomes eafy to crack, when they pour it upon a marble table, grea- fed with oil of fweet almonds, and mould it into vari¬ ous figures with a brafs crotchet. It is eafily falfified with ftarch. ALPHERY (Mikipher), born in Ruffia, and of the Imperial line. When that country was torn to pieces by inteftine quarrels, in the latter end of the 1 d'1* century, and the royal houfe particularly was fo fe* verely perfecuted by impoftors, this gentleman and his. two brothers were fent over to England, and recom¬ mended to the care of Mr Jofeph Bidell, a Ruffia mer¬ chant. Mr Bidell, when they were of age fit for the univerfity, fent them all three to Oxford, where the- fmall-pox unhappily prevailing, two of them died of it. We know not whether this furviving brother took any degrees or not, but it is very probable he did, fince he entered into holy orders; and in the year 1618, had the reftory of Wooley in Huntingtonlhire, a living of no very confiderable value, being rated at under L. 10 in, the king’s books. Here he did his duty with great cheerfulnefs and alacrityand although he was twice invited back to his native country by fome who would have ventured their utmoft to have fet him on the throne of his anceftors, he. chofe rather to re¬ main with his flock, and to ferve God in the humble ftation of a pari (h prieft. Yet in 1643, he underwent the fevered trials from the rage of the fanatics; who, not fatislied with depriving him of his living, infulted him in the mod barbarous manner ; for having procu¬ red a file of mufqueteers to pull him out of his pulpit* as he was preaching on a Sunday, they turned his wife and fmall children into the dreet, into which alfo they threw his goods. The poor man in this didrefs railed him a tent under fome trees in the church-yard, over againd his houfe, where he and his family lived for a week. One day having gotten a few eggs, he picked up fome rotten wood and dry dicks, and with thefe made a fire in the church-porch in order to boil them; but fome of his adverfaries, to (how how far they could carry their rage againd the church, for this poor man was fo harmlefs they could have none againd him, came and kicked about his fire, threw down his Jkillet, and broke his eggs. After this, having dill a little money; he made a fmall purchafe in that neighbourhood, built him* ALP [ 499 1 ALP jUph&is him a houfe5 and lived there fome years. He was en- i Ai . ^ f couraged to this by a preibyterian minifter who came ''i p us‘ in his room, who honellly paid him the fifth part of the annual income of the living, which was the allow¬ ance made by parliament to ejected minifters, treated him with great humanity, and did him all the fervices in his power. It is a great misfortune that this gentle¬ man’s name is not preserved, his conduft in this refpeft being the more laudable, becaufe it was not a little fih- gular. Afterwards, probably on the death or removal ©f this gentleman, Mr Alphery left Huntingtonlhire, and came and refided at Hammerfmith till the Refto- ration put him in pofleffion of his living again. He returned on this occafion to Huntingtonfhire, where he did not ftay long; for being upwards of 80, and withal very infirm, he could not perform the duties of his funftion. Having, therefore, fettled a curate, he re¬ tired to his eldeft foil’s houfe at Hammerfmith, where ihortly after he died, full of years and of honour. ALPHEUS, (Strabo); Alpheius, (Ptolemy); a noted and large river of the Peleponnefus; which, ri¬ ling in, and after feveral windings running through, Arcadia, and by Olympia in Elis, with a fouth-weft courfe, pours into the Sinus Chelonites, about ten miles to the fouth of Olympia. It has a common fpring with the Eurotas, at the foot of mount Parthenius, near the village Afea, (Strabo.) The Alpheus and Eurotas mix and run together for 20 ftadia ; after which, they enter a fubterraneous paffage at Mantinea ; then again emerge, the Eurotas in Laconica, and the Alpheus in the territory of Megalopolis, (Paufanias.) The poets fable ftrange things of this river; particularly, that, out of love to the nymph Arethufu, it runs under the fea to Sicily, and burfts out at the fountain of that name in Syra- cufe, (Virgil). Its waters were reckoned good in the leprofy, which is called A\pof by the Greeks; and hence the name Alpbeas.—Paufanias adds, that the Eleans had a law, which condemned any woman to death that Ihould either appear at the Olympic games, or even crofs this river during that folemnity: and the Eleans add, that the only woman who tranfgrefied it, had dif- guifed herfelf in the habit of a matter or keeper of thefe games, and conducted her fon thither; but when Ihe faw him come off victorious, her joy made her forget her difguife, fo that her fex was difcovered. She was pardoned, but from that time u law was made that the keepers fliould appear there naked- ALPHONSIN, in furgeiy, an inftrument for ex¬ tracting bullets out of gun-fhot wounds. This inftru- mertt derives its name from the inventor Alphonfus Fer- vier, a phyfician of Naples. It confifts of three branch¬ es, which are olofed by a ring. When clofed and in¬ troduced into the wound, the operator draws back the ring towards the handle, upon which the branches o- peningtake hold of the ball; and then the ring is puflr- ed from the haft, by which means the branches grafp the ball fo firmly, as to extraCt it from the wound. ALPHONSUS X, king of Leen and Caftile, fur- tiamed the Wife, was author of the aftronomical tables called Alphonftne. Reading of Quintus Curtius gave • him fuch delight, that it recovered him out of a danger¬ ous illnefs. He read the Bible fourteen times, with fe¬ veral comments on it. He is faid to have found fault with the ftrudture of the mundane fyftem, and has been charged with impiety on that fcore; but Unjitttly, for Afpinl, he only found fault with the involved fyftem of fome A‘rl0‘3' aftronomers. He was dethroned by his fon Sancho ; v and died of grief, A. D. 1284. ALPINI (Pfofpero), a famous phyfician and bo- tanift, born in the Venetian territory, in 1553. He travelled in Egypt to acquire a knowledge of exotic plants, and was the firft who explained the fructifica¬ tion and generation of plants by the fexual fyttem. Upon his return to Venice, in 1586, Andrea Doria, prince of Melfi, appointed him his phyfician : and he diftinguilhed himfelf fo much in this capacity, that he was efteemed the firft phyfician of his age. The repu¬ blic of Venice began to be uneafy, that a fubjeCt of theirs, of fo great merit as Alpini, ihould continue at Genoa, when he might be of fo much fervice and ho¬ nour to their ftate: they therefore recalled him in 1593, to fill the profefforihip of botany at Padua ; and he had a falary of 200 florins, which was after¬ wards raifed to 750. He difcharged this office with great reputation ; but his health became very precari¬ ous, having been much broke by the voyages he had made. According to the regifter of the univerfity of Padua, he died the 5th of February 1617, in the 64^* year of his age ; and was buried the day after, without any funeral pomp, in the church of St Anthony.—Al¬ pini wrote the following works in Latin: 1.

In High Alface there are mines of filver, copper, and media, or common chickweed, with white bloffoms, which is fo well known as to need no particular de- u feription.—This fpecies affords a notable inftance of what is called the Jleep of plants : for, every night, the leaves approach in pairs, fo as to include within lead. They however work none but thofe of Giromany, their upper furfaces the tender rudiments of the new from which are annually drawn 1600 marks of filver, fhoots ; and the uppermoft pair but one at the end of each mark being eight ounces ; and 24,000 pounds of the ftalk are furniflred with longer leaf-ftalks than the copper i but the expence of working them is afmoft equal to the profit. There are iron-works in feveral parts of Alface, and particularly at Betford. There is a mineral fpring at Sultfbach, near Munfter, in High Alface; which is in great reputation for the palfy, weaknefs of the nerves, and the gravel.—The original inhabitants of Alface are honeft and good-natured, but wedded to their own manners and cuffoms. The fruitfulnefs of their country renders them indolent and ina&ive; for the Swifs make their hay and reap their corn. others 5 fo that they can clofe upon the terminating pair, and protect the end of the branch. The young fhoots and leaves, when boiled, can hardly be diftin- guilhed from fpring fpmach. They are deemed refri¬ gerating and nutritive, and an excellent food for per- fons of a confumptive habit of body.—Swine are ex¬ tremely fond of chickweed; cows and horfes eat it; ffieep are indifferent to it; and goats refufe it.

(Anthony); a divine and poet, was edu¬ cated at Weftminfter-fchool, and thence ele&ed to Chrift-church, Oxford, where he took the degree of M. A. in March 1696, and of B. D. in Decern. 1706; On his coming to the univerfity, he was very foon di- ftinguilhed by Dean Aldrich, and publifhed Fabula- rum Mfipicarum Delettus, Oxon.. 1698, 8vo. with a poetical dedication to lord vifeount Scudamore, and a preface in which he took part againft Dr Bentley ia the famous difpute with Mr Boyle. He paffed through the ufual offices in his college to that of cenfor with confiderable reputation ; and for fome years had the principal noblemen and gentlemen.belonging to thefo- ciety committed to his care. In this employment he continued till his merit recommended him to Sir Jona¬ than Trelawney, bifhop of Winchefter, who appointed him his chaplain, and foon after gave him a prebend in his own cathedral, together with the reftory of Bright- well in the county of Berks, which afforded him ample provifion for a learned retirement, from which he could: not be drawn by the repeated felicitations of thefe who thought him qualified for a more public chara&er and a higher ftation. In 1717 an aftion w'as brought a* gainft him by Mrs Elizabeth Aftrey of Oxford, for a breads A L S [ 504 ] A L S -A!fop. breach of a marriage-contraft ; and a verdict obtained v ' againft him for 20001. which probably occafioned him to leave the kingdom for fome time. His death, which happened June 10, 1726, was occafioned by his falling into a ditch that led tp his garden-door. A quarto vo¬ lume was publifhed in 1752, under the title of An- tonrii Alfopi, JEdis ChriJU olim Aluniui Odarum li- Iri duo* Four Englifti poems of his are in Dodfley’s Colledtion, one in Pearch’s, feveralinthe early volumes of the Gentleman’s Magazine, and fome in “ The Stu¬ dent.” Mr Alfop is refpeftfully mentioned by the fa¬ cetious Dr King of the Commons (vol. I. p. 236), as having enriched the commonwealth of learning, by “ TranHations of Fables from Greek, Hebrew, and Arabic and not lefs detraitingly by Dr Bentley, under the name of “ Tony Alfop, a late editor of the iEfopean Fables.” Alsop (Vincent), an eminent divine, was educated in St John’s college in Cambridge, where he took the degree of Mailer of Arts. He received deacon’s or¬ ders from a bilhop, after which he went down into Rut- landlhire, and fettled at Oakham,' where he was an af- fillant to the mailer of the free-fchool. As he was a man of a fprightly turn, he fell there into indifferent company ; but was reclaimed by the frequent admoni¬ tions of the reverend Mr Benjamin King. He after¬ wards married that gentleman’s daughter, and beco¬ ming a convert to his principles, received ordination in the Prefbyterian way, not being fatisfied with that which he had from the bilhop. He was fettled at Wilbee in the county of Northampton, whence he was eje&ed in 1662, for nonconformity. After this he ven¬ tured to preach fometimes at Oakham, and at Welling¬ borough where he lived, and was once fix months in prifon for praying by a fick perfon. A book he wrote againft Dr Sherlock in a humorous ftyle, made him well known to the world, and induced Mr Cawton, an emi¬ nent nonconformift in Weftminfter, to recommend him to his congregation for his fucceffor. On receiving this call, he quitted Northamptonfhire and came to .London, where he preached conftantly, and wrote fe- veral pieces which were extremely well received by the public. His living in the neighbourhood of the cotirt expofed him to many inconveniences ; but thefe ended with the reign of Charles II. or at leaft in the begin¬ ning of the next reign, when Mr Alfop’s fon engaging in treafonable practices was freely pardoned by king James. After this our divine went frequently to court, and is generally fuppofed to have been the perfon who drew the Prefbyterian’s addrefs to that prince fen* his general indulgence. After the Revolution, Mr Alfop gave very public teftimonies of his affection for the go¬ vernment ; yet upon all occafions he fpoke very refpedl- fully of king James, and retained a very high fenfe of his clemency in fparing his only fon. The^remainder of his life he fpent in the exercife of his miniftry, preaching once every Lord’s day; befides which he had a Thurfday lefture, and was one of the lefturers at Pin¬ ner’s hall. He lived to be a very old man, and pre- ferved his fpirits to the laft. On grave fubjedls he wrote with a becoming ferioufnefs ; but where wit might, pro¬ perly be fhovvn, he difplayed his to great advantage. His funeral fermon was preached by Mr Slater, and his memory will be always preferved by his own learned N0 13. and elegant writings.

A branch infinuates itfelf between the fources of the rivers Onon and Ingoda, and thofe of Ichikoi, accompanied with very high mountains, running without interruption to the north-eaft, and dividing the river of Amur, which difcharges itfelf into the eaft, in the Chinefe dominions, from the river Lena and lake Baikal. Another branch ftretches along the Olecma, crofles the Lena below Jakoutfk, and is continued between the two rivers Tongoufka to the Jenefei, where it is loft in wooded and morafly plains. The principal chain, rugged with fliarp-pointed rocks, approaches and keeps near the fhores of the fea of Ockhozt, and palling by the fources of the rivers Oiith, Aldan, and Maia, is diftributed in fmall branches, which range between the eaftern rivers which fall into the Icy Sea ; befides two principal branches, one of which, turning fouth, runs through all Kamtfchatka, and is broken, from the cape Lopatka, into the numerous Kurile illes, and to the eaft forms another marine chain, in the iflands which range from Kamtfchatka to Ame¬ rica ; moft of them, as well as Kamtfchatka itfelf, di- ftinguilhed by fierce vuicanoes, or the traces of vulcanic fires.

ALTAR, a place upon which facrifices were an¬ ciently offered to fome deity.. The heathens -at firft made their altars only of turf; afterwards they were made of ftone, 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 fquare, and others triangular. All of them were turned towards the- eaft, and ftood lower than the ftatues of the gods ; and were generally adorn¬ ed with fculpture, reprefenting either the gods to whom they were erefted, or their fymbols. See the Pagan Altars reprefented on Plate XI. Upon the fides of N° x. a trident and two dolphins are exhibited, which denote it to have been dedicated to Neptune. NJ 2. a four-fquare altar, was dedicated to the nymphs, as the infcription imports. N0 3. exhibits a Bacchanal holding a thyrfus in his hand, a mark of the altar’s be¬ ing built to Bacchus: it had two other fides, which made it appear triangular. Of N° 4. which was alfo triangular, each face or fide exhibited a genius, one of whom (on the fide reprefented) carries an oar upon his neck, which feems to denote it an altar of Neptune. N 5. an altar of a round ftiape, is infcribed //ra Nep- tuni: the god himfelf is there reprefented, all naked, faring the pallium upon his fhoulder; and holding in his left hand a trident, and in his right a- dolphin. The height of altars alfo differed according to the Vol. I. Part II. different gods to whom they facrificed. According to Servius, thofe altars fet apart for the honour of the celeftial gods, and gods of the higher clafs, were placed on fome pretty tall pile of building ; and for that rea- fon were called altaria, from the words alta and ara, “ a high elevated altar.” Thofe appointed, for the terreftrial gods were laid on the furface of the earth, and called ara’. And, on the contrary, they dug into the earth and opened a pit for thofe of the infernal gods, which they called \ctx.x,oit « fcrobiculi.” But this diftinftion is not every where obferved : the beft authors frequently ufe ara as a general word, under which are included the altars of the celeftial and in¬ fernal, as well as thofe of the terreftrial, gods. Wit- nefs Virgil, Eel. 5. -En quatuir arau Where ar# plainly includes altaria ; for whatever we make of Daphnis, Phoebus was certainly a celeftial god. So Gicero, pro Quint. Aras delubraque Hecates in Gracia vidimus. The Greeks alfo diftinguifhed two forts of altars; that whereon they facrificed to the gods was called/Wor, and was a real altar, different from the other whereon they facrificed to the heroes^ which was fmaller, and called Pollux makes this diftinftion of altars in his Onomafticon; he adds, however, that fome poets ufed the word for the altar whereon facrifice was offered to the gods. The Septuagint verfion does fometimes alfo ufe the word urynpet for a fort of little low altar, which may be ex- preffed in Latin by craticula ; being a hearth rather than an altar. Before temples were in ufe, altars were eredted fome¬ times in groves, fometimes in the highways, andfome- times on the tops of mountains ; and it was a cuftojn to engrave upon them the name, enfign, or char after, of the deity to whom they were confecrated. . In the great temples of ancient Rome there were ordinarily three altars: The firft was placed in the fa ac¬ tuary, at the foot of the ftatue of the divinity,- upon which incenfe was burnt and libations offered ; the fe- cond was before the gate of the temple, and upon it they facrificed the riftims; and the third was a portable altar, upon which were placed the offering and the fa- cred veffels. Befides thefe ufes of altars, the ancients fwore upon them, and fwore by them, in making alliances, con¬ firming treaties of peace, and other folemn occafions. Altars alfo ferved as places of refuge to all thofe who fled to them, whatever crime they had committed. Altars are doubtlefs as ancient as facrifices them- felves ; confequently their origin is not much later than that of the world ; Gen. ch. iv. Some attribute their origin to the Egyptians ; others to the Jews; others to the patriarchs before the flood. Some carry them as far back as Adam, whofe altar is much fpoken of by Jewifh, and even Chriftian writers. Others are con¬ tented to make the patriarch Enoch the firft who con¬ fecrated a public altar. Be this as it will, the earlieft ahars we find any exprefs teftimony of are thofe ereft- ed by Abraham. Altars, in the patriarchal times, were very rude. The altar which Jacob fet up at Beth-el was nothing but a ftone, which ferved him inftead of a bolder; that of Gideon, a ftone before his houfe: and the firft which 3 S God ALT [ 506 ] ALT Altar, God commanded Mofes to erect was probably of earth, or unpolUhed ftones, without afiy iron ; for if any ufe was made of that metal, the altar was declared im~ " pure. The principal altars of the Jews were, The altar of incenfe; that of burnt-offering; and the altar, or table, f r the Jhow-bread. The altar of incenfe was a fmall table of fhittim- wood, covered with plates of gold, of one cubit in length, another in width, and two in height. At the four corners, were four kinds of horns, and all round a little border or crown over it. This was the altar hidden by Jeremiah before the captivity; and upon it the officiating prieft offered, every morning and evening, incenfe of a particular compofition. See Plate XL The altar of burnt-offerings was made of fhittim- wood, and carried upon the fhoulders of the priefts by (laves of the fame wood overlaid with brafs. In the time of Mofes, this altar was five cubits fquare and three high ; but in Solomon’s temple it was much lar¬ ger, being 20 cubits fquare and to in height. It was covered with brafs; and at each corner was a horn or (pire, wrought out of the fame wood with the altar, to which the facrifices were tied. Within the hollow was a grate of brafs, on which the fire was made; through it fell the afhes, and were received in a pan below. At the four corners of the grate were four rings and four chains, which kept it up at the horns. This altar was placed in the open air, that the fmoke of the burnt-offerings might not fully the infide of the tabernacle. See Plate XI. The altar, or table, for the Jheox-bread, was likewife of fhittim-wood, covered with plates of gold, having a little border round it,, adorned with fculpture. It was two cubits long, one wide,, and one and an half in height. Upon this table, which flood in the holy of holies, were put, every fabbath-day, 12 loaves,, with fait and incenfe. The Jewifh altars, after their return from the capti¬ vity, and the building of the fecond temple, were in fome refpe£ts different from thofe defcribed above. That of 'burnt-offerings was a large pile, built of un¬ hewn (tone, 32 cubits fquare at the bottom, and 24 fquare at the top. The afcent was by a gentle rifing, 32 cubits in length, and 16 in breadth. Altar, is alfo ufed among Chriflians for the com¬ munion-table. In the primitive church, the altars were only of wood ; as being frequently to be removed from place to place. But the council of Paris, in 509, decreed that no altar fhould be built but of (lone.—At firfl there was but one altar in each church ; but the num¬ ber foon increafed ; and from the writings of Gregory the Great, who lived in the fixth century, we learn, that there were fometimes in the fame church 12 or 13. In the cathedral of Magdeburg there are no lefs than 49 altars. The altar is fometimes fuftained on a fingle column, as in the fubterraneous chapels of St Cecilia, at Rome, fee. ; and fometimes by four' columns, as the altar of St Sebaftian of Crypta Arenaria; but the cuflomary form is, to be a maffive of (lone-work, fuflaining the altar-table. Thefe altars bear a refemblance to tombs : 3 to this purpofe, we read in church-hiftory, that the Altar-thane, primitive Chriflians chiefly held their meeting at the II | tombs of the martyrs, and celebrated the myfteries of A ten’>ul'g’ ijj religion upon them ; for which reafon, it is a (landing rule to this day in the church of Rome, never t,o build an altar, without inclofmg the relics of fome faint in it.

The word comes from altercari, which anciently fignified to converfe or hold difeourfe together.—Thus, we fay, They never come to an open quarrel, but there is continually fome little altercation or other. ALTERN-base, in trigonometry, a term ufed in contradiilindfion to the true bafe. Thus in oblique triangles, the true bafe is either the fum of the fides, and then the difference of the fides is called the altern- bafe; or the true bafe is the difference of the fides, and then the fum of the fides is called the altern-lafe- ALTERNATE, in a general fenfe, a term applied to fuch perfons or things as fucceed each other by turns. Thus, two who command each his day, are faid to have an alternate command, or to command al¬ ternately. Alternate, in heraldry, is faid in refpedf of the fituation of the quarters. Thus the firft and fourth quarters, and the fecond and third, are ufually of the fame nature, and are called alternate quarters. Alternate, in botany, when the leaves or branch¬ es of plants arife higher on oppofite fides alternately. ALTERNATION, in its primary fenfe, denotes a fucceffion by turns. Alternation is fometimes ufed to exprefs the different changes or alterations of orders in any num¬ ber of things propofed. This is alfo called permu¬ tation, &c. and is eafily found by a continual multi¬ plication of all the numbers, beginning at unity. Thus, if it be required to know how many changes or alter¬ nations can be rung on fix bells, multiply the numbers 1,2, 3, 4, 5, 6, continually into one another; and the Jail product gives the number of changes. ALTERNATIVE, is particularly ufed for the choice of two things propofed. In this fenfe we fay, to take the alternative of two propofitions. ALTELEA, Marshmallow: A genus of the po- lyandria order, belonging to the monodelphia clafs of plants; and, in the natural method, ranking under the 3 yth order, Columniferne. The characters are : The calyx is a double perianthium, the exterior one nine-cleft: The corolla confifts of five petals, coalefced at the bafe : Ahhica. The Jlamina confift: of numerous filaments inferted into v'— the corolla ; the antherse are kidney-fhaped. The pi- jlillum has ari orbicular germen ; a ftiort cylindrical fty- lus ; and numerous briltly ftigmata, the length of the ftylus : The pericarpium confills of numerous arilke : The feeds are folitary, and kidney-ftiaped. There arc three / Species. 1. The vulgaris, or common marfhmallow. is a native of Britain, and hath a perennial root, and an annual ftalk, which periihes every autumn. The ftalks grow ere£t to the height of four or five feet. Thefe are garniftied with leaves which are hoary, foft to the touch, and placed alternately on the branches. The fiowei s come out from under the wings of the leaves, like the mallow, and are of a purplifli white. 2. The hirfuta, or hairy marfhmallow, is a native of Spain and Portugal. It is a low plant, whofe branches trail on the ground, unlefs they are fupported by ftakeS. The leaves and ftalks are befet with ftrong hairs, the flowers come out like thofe of the common fort, but are fmall- er, and have purplifh bottoms. 3. The cannabina, or fhrubby marfhmallow, is a native of Hungary and If- tria. It has a woody ftem, which rifes to the height of four or five feet; and puts out many fide-branches. The flowers come out in the fame manner as in the others, but are of a deeper red colour. This fort feldom flow¬ ers the firft year, unlefs the fummer proves warm ; but when the plants live through the winter, they will flower early in the following fummer, and produce good feeds. Culture.- Though the firft fort is found naturally in fait marfhes, it will thrive when tranfplanted into any foil, or in any fituation ; however, it will always grow larger in moift than in dry foil. It may be propagated either by parting the roots in autumn when the ftalks decay, or by lowing the feeds in the fpring. If the feeds of the fecond fpecies are fown in April, the plants will flower in July, and carry ripe feed in September. They ought to be fown in the places where they are to remain, as the roots fhoot deep in the ground; fo that unlefs the plants are removed very young, they feldom furvive it. The feeds of the cannabina ought alfo to be fown where the plants are to remain, for the reafon juft now given. They fhould have a flickered fituation and a dry foil, otherwife they will not live through the winter. Indeed they feldom continue in this country above two years, with all the care that can be taken of them. Medicinal Ufes. The firft is the only fpecies ufed in medicine. The whole plant, efpecially the root, a- bounds with a mild mucilage. It has the general vir¬ tues of an emollient medicine ; and proves ferviceable in a thin acrimonious, ftate of the juices, and where the natural mucus of the inteftines is abraded. It is chief¬ ly recommended in (harp defluxions upon the lungs, hoarfenefs, dyfenteries ; and likewjfe in nephritic and calculous complaints: not, as fome have fuppofed, that this medicine has any peculiar power of diffolving or expelling the calculus; but as, by lubricating and re¬ laxing the veffels, it procures a more free and eafy paf- fage. The root is fometimes employed externally for foftening and maturating hard tumours; chewed, it is faid to give eafe in difficult dentition of children. This root gave name to an officinal fyrup, decoc- 3 S 2 ' tion, ALT [ 508 ] ALT tion, and ointment j and was likewife an ingredient in the compound powder of gum tragacanth and the oil and plailer of mucilages. But of all thefe formulae the fyrup alone is now retained, SUthjea Frutex. See Hibiscus. ALTIMETRY, the art of meafuring altitudes or heights, whether acceffible or inacceffible. See Geo¬ metry. ALTIN, a money of account in Mirfcovy, worth three copecs; one hundred of which make a ruble, worth about 4s. 6d^ fterling. ALTIN, a lake in Siberia,, from whence ifTues the river Ob, or Oby, in N. Lat. 52. o. E. Long. 85°. 55'. This lake is called by the Ruffians Telojkoi Qfero, from the Teleffi, a Tartarian nation, who inhabit the borders of it, and who give it the name of Altin-Kul. By the Calmucks it is called'It is near ninety miles long and 50 broad, with a rocky bottom.; The north part of it is fometimes frozen fo hard as to be paffable on foot, but the fouthern part is never covered with ice. The water in the Akin lake, as well as in the ri¬ vers which run through the adjacent places, only rifes in the middle of fummer, when the fnows on the moun¬ tains are melted by the heat of the fun. ALTINCAR, among mineralifts, a fpecies of fac¬ titious fait ufed in the fuiion and purification of metals. The altincar is a fort of flux powder.. Divers ways of preparing it are given by Libavius. ALTING (Henry), profeffor of divinity at Hei¬ delberg and Groningen, was born at Embden in 1583, of a family which had been long confpicuous in Frifeland. His father, Menfo Altihg, was the firfl, who, with two others, preached the reformation in the territory of Groningen, about the year 156$, under the tyrannical government of the duke of Alva ; and the firft that preached in the.great church of Gronin¬ gen, after the redudtion of that town by the States Ge¬ neral in 1594. Henry was chofen, in 1605, preceptor to the three young counts of Naffau, Solms, and Izen- berg. After various difficulties, he fettled at Gronin¬ gen, where he continued till his death,-Augufl 25. 1644. He was a found protefHnt divine, a pious Ghriflian, a ufeful member of fociety in many refpects, and one who fuffered much for the truth. Mod of his Works were never publifhed; thofe which have been are the following: Not* in decadent prableinatum J, Behm, 1618. Loci communes explicatio catecbefeos Pa- latinee, 1646, in 3 vols. Exegtjis Augujianx confef. 1647. Methodus theologies, 1650. It appears from the catalogue of his works annexed to his life, that the Medulla hiji. prophanx, publifhed by Dr Pareus, was compofed by Alting. The mod remarkable piece a- mong Alting’s MMS. is, The ecclefiadical hidory of the Palatinate, from the reformation to the adminidra- tion of John Cafimir. Alting (James), fon of the former, was born at Heidelberg in 1618. He travelled into England in 1640, where he was ordained by the learned Dr Pri- deaux, biffiop of Worceder. Pie afterwards accepted of the profefforfhip of Groningen, vacant by the death of Gomarus; but his fituation was rendered very dif- agreeable by the continual difputes which he had with his colleague Sam. des Marets, who favoured the fchool- divinity. He died in 1697. He recortimended the edi¬ tion of his works to Menfo Alting (author of Notitia German. Infer. Atriiqua, fol. Amd. 1679) ; but they were publilhed in 5 vols. folio, with his life, by Mr Bekker of Amderdam. They contain various analy¬ tical, exegetical, practical, problematical, and philofo- phical tradls, which fhow his great indudry and know¬ ledge. Alting was a divine greatly addicted to the text of the fcripture, to Cocceianifm, and Rabbinifm. He. preached well in German, Dutch, and Englifh. ALTITUDE, acceffible, and inacceffible. See Geometry, The method of taking eonfiderable terredrial, alti¬ tudes, of which thofe of mountains are the greatedj by means of the barometer, is very eafy and expeditious. It is done by obferving, on the top of the mountain, how much the mercury has fallen below what it was at the foot of the mountain. See Barometer. . Altitude of the Eye, 'in perfpeftive, is a right line let fall from the eye, perpendicular to the geometrical' plane-. Altitube, in adronomy,- is the didance of a dar,. or other point, in the mundane fphere, from the ho¬ rizon. This altitude may be either true or apparent.—If it be taken from the rational or real horizon,, the altitude is faid to be true or real;. if from the apparent or fen— fible horizon, the altitude is apparent.—Or rather, the., apparent altitude is fuch as it appears to our obferva- tion-,- and the true is that from which the refraction has been fubtradted. The true altitudes of the fun, fixed dars, and planets,, differ but very little from their, apparent altitudes; be- caufe of . their great didance from the centre of the earth, and the fmallnefs of the earth’s femidiameter, „ when compared thereto. But the difference between the true and apparent altitude of the moon is about 52'. This fubject is further explained under Astro¬ nomy.

He was therefore recalled; and, being invelted with his ufual authority, revenged him- felf feverely upon his enemies, by perfuading the king to'banifh them. Of the 45 years he fpent at court, he enjoyed for 30 of them fo entire an afcendancy o- ver the king, that nothing could be done without his exprefs orders: nay, it is related by Mariana, that the Alto-Ripieno, in mufic, the tenor of the great king could not change an officer or fervant, or even •chorus which fxngs and plays only now and then in Tome particular places.

ALVARES d'e luna, or as fome call him Alva¬ ro, is a charadfer too edifying to be omitted in this work. He was the favourite of John II. king of Ca- ftile: was famous for the prodigious afcendancy he gained over this prince,. and for the punifhment which at length overtook him. He was natural fon of Don Alvaro de Luna, lord of Canete in Arragon, and of a woman infamous for unbounded luft. He was born in 1388, and named Peter; but Pope Benedict XIII. who was charmed with his wit tho'" yet a child, changed Pe¬ ter to Alvares. He was introduced to court in 1408, and made a gentleman of the bedchamber to king John, with whom he grew into the higheft favour. In 1427 he was obliged to retire: the courtiers exerted all their endeavours to ruin him ; they complained, that a man of no military fldll, of no virtues whatever, fliould, by mere artifice and difiimulation, be advanced to the higheft authority; and they could not bear that, by the affiftance of a few upftart men, whom he had raifed and fixed to his intereft, he fhould reign as ab- folutely as if he were king. They prevailed againft him, and Alvares was banilh- ed from court a year and an half: but this was the greateft affliction imaginable to the king; who ftiow- 4, But the day of reckoning was approaching;, and at length he was feized ; yet not direftly, openly, and vio¬ lently, but with fome of that management which up¬ on a fimilar occafion was formerly employed by Tibe¬ rius againft Sejanus. During his confinement^ he made feveral attempts to fpeak to the king in perfon ; but not being able to effeCt this, he lent the following let¬ ter, from which, as well as from the reft of Al- vares’s hiftory, all court favourites may draw abundant matter for edification and inftruciion; “ Sir, it is five- “ and forty years fince I was admitted into your fer- “ vice. I do not complain of the rewards I have re- “ ceived s.they were greater than my merits or expec- “ tation, as I fliall not deny. There was but one “ thing wanting to'complete my happinefs ; and that “ was to have fixed proper limits in time to this great “ fortune of mine. While, inftead of choofing retire- “ ment, after the example of the greateft men, I ftili “ Continued in the employment, which I thought not “ only my duty, but neceflary for your intereft, I fell “ into this misfortune. It is very hard that I fiiould “ be deprived of liberty, when I have Hiked life and “ fortune more than once to reftore it to you. Grief “ prevents me from faying more. I know that the “ Deity is provoked againft me by my fins; but it will be fufficient for me, if his anger is appeafed by the “ calamities I now fuffer. I can no longer bear that “ prodigious mafs of riches, which it was wrong in “ me to have heaped together. I. ihould willingly “ refign them, but that every thing I have is in your “ power; and I am denied the opportunity of ftiowing “ mankind, that you have raifed a perfon to the height “ of greatnefs, who can contemn wealth as well as pro- “ cure it, and give it back to him from whom he re- “ ceived it. But I defire you in the ftrongeft terms, “ that, as I was obliged by the lownefs of the trea- “ fury to raife 10,000 or 12,000 crowns by methods “ I ought not to. have taken, you will reftore them to “ the perfons from whom they were extorted- If you “ will not grant this on account of the fervices I have “ done, yet I think it neceflary to be done from the “ reafon of the thing.” This letter, however, produced no effeft in his fa¬ vour : Alvares was tried, and condemned to lofe his head. After condemnation, he was removed to Valladolid; and, having 'confefled himfelf, and received the facra- ment, he was carried upon a mule to the market-place, ALU [ 510 ] ALU Aludeh in the middle of which a large fcaffold was ere&ed. II Mounting the fcaffold, he paid reverence to the croff, . “m' , and prefently gave his hat and fignet to his page, fay¬ ing, “ Thefe are the laft gifts you will ever receive “ from me.” He then fubmitted himfelf to the axe with the utmoft intrepidity. Dr Geddes relates, that Jie was executed the 4th of June, others the 5th of July, 1453. ALUDELS, in chermftry, are earthen pots with¬ out bottoms, inferted into each other, and ufed in fub- limations. ALVEARIUM, in anatomy, the bottom of the concha, or hollow of the outer ear. Alvearium alfo fignifies a bee-hive. The word is formed of alveus, a “ channel or cavity in allufion to the. alveoli, or cells in bee-hives. Some of the ancients ufe alfo the word alvearium for a bee-houfe, more ufually called among us apiary. Alveariiim is fometimes alfo ufed figuratively, to denote a collection. In which fenfe, alvearium amounts to much the fame with what we otherwife call thefau- rus, cornucopia, or the like. Vine. Boreus has publiih- cd an alvearium of law. ALVEOLUS, in natural hiftory, the name of the waxen cells in bee hives. Alfo the name of a fea-follil of a conic figure, compofed of a number of cells, like bee-hives, joined into each other, with a pipe of com¬ munication. Alveolus, in anatomy, the fockets in the jaws wherein the teeth are fixed.— Some writers fpeak of teeth growing without alveoli. Pliny mentions a per- fon who had a tooth in his palate. Euftachius relates, that he faw a man who at 60 had a tooth growing out ©f the middle of his fauces. Holler gives an inllance of a perfon, whofe teeth were of a piece with his jaws, ^ without any infertion into alveoli. , ALUM, in chemiftry, a clear and tranfparent fa- [f line matter, ufually fold in large maffes, of a very a u ft ere and aftringent tafte, ufeful in medicine and in various arts. Moft of the alum to be met with is artificially pre¬ pared by the methods related in their proper place under the article Chemistry, or by others fimilar to them ; though fometimes a fmall quantity is produced naturally. This native alum is mixed with heterogeneous matters, or efflorefees in various forms upon the ores during cal¬ cination. It rarely occurs in a cryftallized ftate, though thus it is faid to be met with in Egypt, Sardinia, Spain, Bohemia, and other places. It is alfo found in the wa¬ ters, impregnated with fixed air, but very feldom in fountains or hot medicated waters. There are .feveral kinds of alum to be met with ; but thefe differ from one another only in being mixed with fome falts which are not of the aluminous kind. That called the Roman alum has been confidered as preferable to any other. This is ufually met with in imall cryftals, and has a reddifh colour, moft probably owing to a fmall quantity of calx of iron, which, how¬ ever, does not in the leaft impair its qualities. The other kinds of alum contain a portion either of vitrio- ' bated tartar or fal ammoniac, according to the nature of the alkali ufed in its preparation. Mr Bergman in¬ forms us, that the vegetable alkali, if pure, docs not hurt the alum, though it be added in the preparation ; ■hut that the volatile alkali, by adulterating it with a portion of vitriolic fai ammoniac, renders it unfit for Alum, fome purpofes. The alum, made by adding a portion ——v— of clay to the liquor at the beginning of the boiling, he confiders as equal, if not fuperior, to Roman alum. He informs us alfo, that a kind of alum fome time ago began to be manufactured at Brunfwick, which was equal in quality to the Roman alum. On a chemical analyfis of this alum he found it mixed with cobalt. This fait is extremely ufeful in the art of dyeing; as by means of it a great number of colours are fixed and rendered permanent upon cloth, which otherwife would either not adhere in any degree, or only for a very Ihort time. In what manner this is accomplilhed we are very much ignorant; the conjectures and theories on this fubjeCt are related under the article Dyeing. It conftitutes the bafis of crayons, which generally confift of the earth of alum finely powdered and tinged for the purpofe. In the preparation of Pruftian blue, it prevents the bafis of martial vitriol, which is foluble in acids, from being precipitated by the fuperfluous al¬ kali employed in the preparation of that pigment; that is, the alkali which is not faturated by the colouring matter. As this bafis adheres more ftrongly than the clay to the vitriolic acid, and would form a green by the mixture of its yellownefs, the white earth of alum likewife, according to its quantity, dilutes the darker colours, even black itfelf, and produces an infinite number of ftiades. It is alfo of ufe in the making of candles ; for being mixed with the tallow, it gives it an hardnefs and confiftence which it has not naturally. Wood fufficiently foaked in a folution of alum does not eafily take fire, and the fame is true of paper impreg¬ nated with it; which for that reafon is very properly employed in preferving gun-powder, as it alfo excludes the moifture of the air. Paper impregnated with alum is ufeful in whitening filver, and filvering brafs without heat. Alum is alfo of ufe in tanning, where it afiifts in reftoring the cohefion of the Ikins almoft entirely de- ftroyed by the lime. Vintners fine down their wines, &c. with alum ; filhers ufe it to dry codfilh with ; and ba¬ kers have mixed it with the flour to make their bread compaft and white : to this laft ufe of it great objec¬ tions have been made, but unjuftly, for it is entirely in¬ nocent, and now feldom ufed. In medicine it is of confiderable ufe as an aftringent and tonic. It is reckoned particularly ferviceable for reftraining hemorrhagies, and immoderate fecretions from the blood ; but lefs proper in inteftinal fluxes. In violent hemorrhagies, it may be given in dofes of 15 or 20 grains, and repeated every hour or half hour till the bleeding abates: in other cafes, fmaller dofes are more advifable ; large ones being apt to naufeate the ftomach, and occafion violent conftipations of the bowels. It is ufed alfo externally, in aftringent and repellent lotions and collyria. Burnt alum taken in¬ ternally has been highly extolled in cafes of colic. In fuch inftances, when taken to the extent of a fcruple for a dofe, it has been faid gently to move the belly, and give very great relief from the fevere pain. Its officinal preparations are, for internal ufe, pulvis Jlyp- ticus, and aqua Jlyptica for external applications, the aqua aluminis, and coagulum aluminis and alumen ufhim ; which laft is no other than the alum dried by fire, or freed from the watery moifture, which, like o- ther falts, it always retains in its cryftalline fqrm.

For thefe preparations, fee Phar¬ macy. Alvm minet are faid to have been firll found in Italy in the year 1460 ; and in 1506 king Henry VII. made a monopolizing grant of this commodity to Au- guftine Chigi, a merchant of Sienna. In the year 1608 the manufafture of alum was firit invented, and fucceflively praftifed in England, meeting with great encouragement in Yorkfhire, where it was firll made, from Eord Sheffield, and other gentleman of that county. King James I. by advice of his minillry, af- fpmed the monopoly of it to himfelf, and therefore prohibited the importation of foreign alum; and in 1625 the importation of it was further prohibited by the proclamation of Charles I. /huM-works, places where alum is prepared, and manufaftured in quantities for fale. They differ from alum-mines, as in the former an artificial alum, and in the latter natural alum, is produced. ALUNTIUM, Alontium, (anc. geog.) a town in the north of Sicily, fituated on a fteep eminence, at the mouth of the Chydas; faid to be as old as the war of Troy. Now in ruins; from which arofe the ham¬ let St Filadelfo, in the Val di Demona. The inha¬ bitants were called Haluntini. ALVUS, in anatomy, a term ufed for the belly in general, but more frequently applied to the bowels. ALWAIDII, a feft of Mahometans who believe all great crimes to be unpardonable.—The Alwadii Hand in oppofition to the Morgii. They attribute lefs efficacy to the true belief in the falvation of men than the reft of the Muffelmans. ALYSSUM, Allysok, orAllysoides, Madwort; (from aAuo-o-u, to be mad; becaufe it was believed to have the property of curing madnefs) : A genus of the filiculofa order, belonging to the tetradynamia clafs of plants j and, in the natural method, ranking under the 39th order, Sihquofa. The charafters are : The calyx is an oblong four-leav’d perianthium : The corolla con- fifts of four cruciform petals ; with claws the length of the calyx, the petals fhorter: The Jlamina confift of fix filaments, the length of the calyx, two of them ra¬ ther fhorter and denticulated; the antherae are ereft and expanding : The pljlilium has an ovate germen ; the ftylus is fimple, and the length of the flamina; the ftigma is obtufe: The pericarpium is a fub-globular emarginated filicle, furnifhed with a bilocular ftylus, having an elliptic partition : The feeds are few, orbi¬ cular, and affixed to filiform receptacles. Species. Of this genus, Linnaeus enumerates 19 fpecies; but none of them are remarkable either for beauty, or any other property, except the halimifo- lium, or madwort with whole fpear-fhaped leaves. This fpreads itfelf upon the ground, and never rifes to any height. It produces, at the extremity of its branches, very pretty tufts of fmall white flowers ; of which it is feldom deftitute for fix or feven months fuccefiively ; for which reafon it well deferves a place in the gardens of the curious. Culture. Though thefe plants are natives of the fbuthern parts of Europe ; yet, if planted on a dry, lean, or rubbifhy foil, they will endure our fevereft win¬ ters in the open air.—-The halimifolium feldom conti- Alytarcha nues above two or three years, and muft therefore be Ama|aj,at often fown to preferve it; or if the feeds are fuffered > ^ 1 to fall, the plants will rife without any trouble. It may-alfo be propagated by cuttings, which ought to be planted in April or May, and are very apt to take root, if kept fhaded in the heat of the day, and gently refreflied with water. This plant, as already obferved, was thought to cure fome kinds of madnefs; but the preferj; praftice has entirely rejefted it for this or any other purpofe.

The city Hands in a beautiful plain ; and is watered by the little river Sabremetti, which, though not deep, in time of rains overflows the plains prodigioufly. The walls are built with Hone and brick, flanked at certain di- ftances with great round towers and battlements. It has twelve gates ; and, including the fuburbs, is about four miles and an half long.

The A M A The ground of the enmity of the Amalekites againft the Ifraelites is generally fuppofed to have been an in¬ nate hatred from the remembrance of Jacob’s depri¬ ving their progenitor both of his birthright and blef- fmg. Their falling upon them, however, and that without any provocation, when they faw them reduced to fo low a condition by the fatigue of their march and the exceffive drought they laboured under, was an inhuman a&ion, and juftly deferved the defeat which Jofhua gave them. Under the Judges (v. 3.), we fee the Amalekites united with the Midianites and Moab¬ ites, in a delign to opprefs Ifrael; but Elrud delivered the Ifraelites from Eglon king of the Moabites (Judges iii.), and Gideon (chap, viii.) delivered them from the Midianites and Amalekites. About the year of the world 2930, Saul marched againfl the Amalekites, ad¬ vanced as far as their capital, and put all the people of the country to the fword; but fpared the beft of all the cattle and moveables, contrary to a divine com¬ mand; which a£! of difobedience was the caufe of Saul’s future misfortunes. After this war, the Amalekites fcarce appear any more in hiftory. However, about the year of the w'orld 2949, a troop of Amalekites came and pillaged Ziklag, which belonged to David (1 Sam. xxx.), wdiere he had left his two wives Ahinoam and Abigail; but he returning from an expedition which he had made in the company of Achifh into the valley of Jezreel, pur- fued them, overtook and difperfed them, and recover¬ ed all the booty which they had carried off from Zik- la£- The Arabians maintain Amalek to have been the fon of Ham and grandfon of Noah ; that he was the father of Ad and grandfather of Schedad. Calmet thinks that this opinion is by no means to be reje&ed; as it is not very probable that Amalek the fon of Eli- phaz, and grandfon of Efau, Ihould be the father of a people fo powerful and numerous as the Amalekites were when the Ifraelites departed out of Egypt. Mofes in the book of Genefis (xiv. 7,) relates, that in Abra¬ ham’s time, long before the birth of Amalek the fon ' of Eliphaz, the five confederate kings carried the war into Amalek’s country, about Kadefli; and into that of the Amorites, about Hazezontamar. The fame Mofes (Numb. xxiv. 20.) relates, that the diviner Ba¬ laam, obferving at a diftance the land of Amalek, faid, in his prophetic ftyle, “ Amalek is the firft, the head, the original of the nations ; but his latter end ihall be that he perifii for ever.” Our commentator obferves, that this epithet of the firft of nations cannot certainly agree with the Amalekites defcended from the fon of Eliphaz, becaufe the generation then living was but the third from Amalek. Befides, Mofes never re¬ proaches the Amalekites with attacking their brethren the Ifraelites; an aggravating circumftance which he would not have omitted were the Amalekites defcended' from Efau; in which cafe they had been the brethren of the Ifraelites. Laftly, We fee the Amalekites almoft always joined in the Scripture with the Canaanites and Philiftines, and never with the Edomites; and when Saul made war upon the Amalekites, and almoft utterly de- ftroyed them, we do not find that the Edomites made the leaft: motion towards their afliftance, nor to revenge them .afterwards. Thence it is thought probable, that the Amalekites who are fo often mentioned in Scrip- Vot. I. Part II. A M A ture were a free people defcended from Canaan, and Air,a' devoted to the curfe as well as the other Amorites, and , ' ma “ very different from the defendants of Amalek the y grandfon of Efau. The accounts which the Arabians give us of the Amalekites deftroyed by Saul are as follow. Amalek was the father of an ancient tribe in Arabia, extermi¬ nated in the reign of Saul. This tribe contained only the Arabians who are called Pure; the remains where¬ of were mingled with the pofterity of Joktan and Ad- nan, and fo became Mofarabes or Moftaarabes ; that is to fay, Arabians blended with foreign nations. They farther believe, that Goliah, who was overcome by David, was king of the Amalekites; and that the giants who inhabited Paleftine in Jofhua’s time were of the fame race. That at laft part of the Amalekites retired into Afric while Jofliua was yet living, and fet¬ tled upon the coafts of Barbary, along the Mediterra¬ nean fea. The fon of Amalek was Ad, a celebrated prince among the Arabians. Some make him the fon of Uz, and grandfon of Aram the fon of Shem. Let this be as it will, the Mahometans fay that Ad was the father of an Arabian tribe called /Idites; who were exterminated, as they tell us, for not hearkening to the patriarch Eber, who preached the unity of God to them. Ad had two fons, Schedad and Schedid. AMALFI, an ancient city of Italy, fituated in E. Long. 15. 20. N. Lat. 40. 35.—It is faid to have de¬ rived its origin from a number of Roman families, who, about the middle of the fourth century, either from private views of emolument, or in confequence of com- pulfory orders from the emperor, had left Rome and embarked for Conftantinople; but meeting with ftorms on their paffage, were caft away on the fliores of Sa¬ lerno, and deprived of the means of purfuing their voyage. In this ftate of perplexity they long remain¬ ed, but at laft came to the refolution of fettling on the prefent fite of Amalfi, where they expedted to enjoy fecurity and fufficient plenty of the neceffaries of life. The earlieft notice of them in this fettlement dates no higher than the latter end of the fixth century. Im¬ pervious mountains and inacceffible coafts preferved their infant ftate from the firft fury of the Lombards, who feldom attempted the conqueft of'a maritime people. . In the year 825, when this little republic had, under the patronage of the eaftern emperors, attained a der gree of wealth and reputation fufficient to excite the ambition of its neighbours, Sico, prince of Salerno, marched a body of troops by night; furprifed Amalfi; and, carrying off the greateft part of the inhabitants, compelled them to fix at Salerno, which had lately fuffered a great lofs of people by an epidemical difor- der. But before the fourth year of their captivity was expired, the Amalfitans took advantage of the abfence of the Salernitan chiefs, who were than carrying on a war with the Beneventans ; armed themfelves ; and, after burning and plundering Salerno, marched in tri¬ umph back to their own country. Here they framed a better fyftem of government, and reformed many abufes in their former legiftation ; adopting various meafures that were likely to promote internal concord and defeat the evil intentions of fo¬ reign enemies. Their firft plan was to veil the fupreme authority in a temporary prefect; but the experience [ 513 1 A M A [ 5H 1 A M A Amalfi of a few years caufed them to prefer lodging that heat; neverthelefs, heat confiderably facilitates the o- Amalthaa power in the hands of a duke eledfed for the term of peration, . puwci lil LilC iictuud tJl Cl UUA.C Itli Lilt U1 VJI. mation. natural life.

L,eo IV. found the Amalfitans an ufeful ally in his wars with the infidels, and honoured the commonwealth with the title of Defender of the Faith. The Neapo¬ litans, with whom, as Greek vaffals, they were uni¬ ted in flridl bonds of friendlhip, experienced many fig- nal favours at their hands ; and the Muffulmen them- felves found it expedient to court their alliance, and to enter into treaty with them. Their fituation had from the beginning given them a turn to commerce, and their attention to naval affairs fo much confequence in the eyes of their proteftor, the emperor of Conflanti- fiople, that by his orders a court was eftablifhed at Amalfi for the decifion of all controverfies ariling in maritime tranfaftions. Its code and reports became the general rule in thofe cafes throughout this part of Eu¬ rope •, its precedents and decrees were allowed to be good authority to found judgment upon even in foreign tribunals.—To crown the mercantile and naval glory of the republic, it was referred to the lot of an Amal- fitan to make, or at leafl to perfedt, the moft import¬ ant difcovery ever made for the improvement of navi¬ gation.

If it be gold or filver, it is fufficient to ftir the fluid with an iron rod for a little while, and then throw it into a veflel filled with water. This amalgam is ufed for gilding or filvering on copper, which is afterwards expofed to a degree of heat fufficient to evaporate the mercury. Amalgamation with lead or tin is effected by pour¬ ing an equal weight of mercury into either of thefe metals in a ftate of fufion, and fliiring with an iron rod.

When the plants are in full vigour, the leaves are large, and clofely fet from the bottom to the top of the ftalks, and the branches form a fort of pyramid; fo that there is not a more beautiful plant than this when it is in full luftre. 2. The melancho- licus, bicolor, of- two-coloured amaranthus. This greatly refembles the former in its manner of growth ; but the leaves have only two colours, which are an obfcure purple, and a bright crimfon. Thefe are fo blended as to fet off each other, and, when the plants are vigorous, make a fine appearance. 3. The caudata, with very long hanging cylindrical fpikes. This fpe- eies is a native of America. It hath an upright ftem three feet high; the leaves and ftalks are of a pale green colour. The fpikes of flowers are produced from the wings of the ftalks, and alfo at the extre¬ mities of the branches. They are of a bright purple colour, and hang downward, fometimes to the length , of two feet and an half, fo that many of them touch the ground. 4. The maximus, or tree-like amaran¬ thus, grows with a ftrong ftem, to the. height of feven or eight feet. Towards the top it fends forth manyr horizontal branches, garniftied' with oblong rough green leaves. At the extremity of every fhbot, the cylindrical fpikes of flowers are produced. They are of a purple colour, and hang downward like the laft; but are feldom half the length, tho’ much thick¬ er than the former. 5. The fanguineus, with com¬ pound fpikes, and oblong oval leaves.. This is a na¬ tive of the Bahama iflands. It is an efculent plant, and bears fine flowers.. It grows to the height of three feet, with purple ftalks and leaves. The fpikes are fliort and cylindrical, , of-, a bright purple at firft, but after¬ wards fade to a darket colour. They are frequently produced from the wings of the ftalks; but at the ex¬ tremity of the ftalk arifes a large clufter of fpikes, which are placed crofs-wife, with one upright ftalk in the middle. 6. The, oleraceus, with obtufe indent¬ ed leaves.:. This has no beauty ; but it is ufed by the Indians as a fubftitute to cabbage. Culture. The two firft of thefe fpecies being ten¬ der, require fome art and care to bring them to per¬ fection in Britain, by a fucceffion of hot-bed, with proper waterings, airings, and fhadings. Where people are curious in having thefe annual plants in great perfection, there ftiould be a glafs-cafe ereCted, with upright and Hoping glafles on every fide, with a pit in the bottom for tan, in which the pots {hould be plunged. If this is raifed eight or nine feet to the ridge, and the upright glafles are five feet, there will be room enough to raife thefe and other annual plants to great perfection ; and in fuch a building* many tender vegetables, which rarely perfeCt their feeds in this climate, may be every year brought forward fo as. to ripen their feeds. AMARYLLIS, lily-asphqdel : A genus of the 6 ] A M A monogynia order, belonging to the hexandria clafs of AmaryIIi*| plants; and, in the natural method, ranking under the 9th order, Spathaceee. The charaCters are : The calyx is an oblong obtufe fpatha, emarginated, and wither¬ ing : The corolla confifts of fix petals, lanced: The. Jlaviina confift of fix Tubulated filaments; the anther® oblong, incumbent, and afeending : The pijlillum has-, a roundifh fulcated germen beneath ; a filiform ftylus,. nearly the length of the ftamina ; the ftigma trifid and flender: The pericarpium is an ovate trilocular capfule, with three valves: The feeds are many. Principal Species. 1. The lutea, or autumnal narciffus.. This is ufually fold by gardeners, along with colchicums,, for autumnal ornaments to gardens. For this purpofe it is very proper, as it will keep flowering from the begin¬ ning of September to the middle of November, provided the froft is not fo fevere as to deftroy the flowers. Al¬ though there is but one flower in each cover, yet there is a fucceflion of flowers from the -fame root, efpecially when they are fuffered to . remain three or four years unremoved. The flowers feldom rife above three or four inches high. They are fliaped fomewhat like the flowers of the yellow crocus; the green leaves come up at the fame time, like the faffron ; and, after the flow¬ ers are paft,. the leaves increafe all the winter. The rootsare bulbous, and fliaped like thofe of the n arc if- fus; fo are proper ornaments for fuch borders as are planted with cyclamens, faffron, autumnal crocus, col¬ chicums, and fuch low autumnal flowers. 2. The formofiffima, or jacohaea lily, produces its flowers J two or three times in a year, without being regu¬ lar to any feafon. The flowers are of a deep red, the under petals very large, and the whole flower flands nodding on one fide of the ftalk, making a beautiful ap¬ pearance. The Items of thefe flowers are produced from the iides of the bulbs ; fo that when the flowers produ¬ ced on one fide are decayed, another italk arifes from the other fide of the bulb; but there is no more than one- flower produced on the fame ftalk. When the roots are in vigour, flowers will be produced from March to the beginning of September. 3. The far- nienfis, or Guernfey lily, is fuppofed to have come ori¬ ginally from Japan, but has been many years cultivated in the gardens of Guernfey and Jerfey ; in both which- places they feem to thrive as well as if it was their na¬ tive country, and from thefe iflands their roots are fent annually to the curious in moft parts of Europe. The flowers of this fpecies are admired for the richnefs . of their colour, which is commonly red, though they have no feent. They-appear towards the end of Sep¬ tember ; and, if properly managed, will continue a month in beauty. The roots of thefe plants do not flower again the fucceeding year, as is the cafe with many other bulbs : but if their bulbs contain two buds in their centre, which is often the cafe, they frequent¬ ly flower twice in three years ; after which the fame in¬ dividual root does not flower again in feveral years, but only the offsets from it. 4. The regina, or belladon- . na lily, is a native of Portugal, where it was formerly cultivated in great plenty ; but of late it lias been fup- planted by the jacohrea lily, fo that the roots which have been brought. from that country for.fome time paft for the belladonna, have generally proved the ja- cobsea lily. This kind, if properly managed, will fometimes put out two or three items, growing near three A M A [5 Amaryllis, three feet high, and produce many flowers in each um- Arnaryn- make a fine appearance during the month . 1 Us~ 1 of Oftober. 5. The zeylanica, or Ceylon lily, is a native of the Weft Indies, and ufually flowers in June. Sometimes the fame root will' flower again in autumn, but the flowers are of no long duration. 6. The ori- entalis, or lily daffodil, with leaves ftiaped like a tongue. This is a native of the Cape of Good Hope. The bulbs of the root are large and almoft round; the leaves long, broad, and rounded at their extremities ; thefe fpread two ways on the furface of the ground, and do not come up till after the flower-ftem appears, which is generally in November. After the flowers are paft, the leaves in- creafe till fpring, and in May they begin to decay ; fo that from the middle of June to Odtober the roots are entirely deftitute of leaves. Culture. The firft fort is very hardy, and will thrive in almoft any foil or firuation ; but will fucceed beft in a freflx light dry foil, and not too near the dripping of trees, or too near walls. It increafes very fall by off- fets, by which all the other fpecies are alfo to be pro¬ pagated. Thefe roots may be tranfplanted any time from May to the end of July ; after which it will be too lateto remove them.—The jacobsea ought to be keptina moderate ftove all winter ; in which cafe it will fend forth plenty of offsets, that will produce vigorous plants.— The roots of the Guernfey lily are generally brought over in June and July ; but the fooner they are taken, out of the ground after the leaves decay, the.better: for alt ho’ the roots which are taken up when their flower- ftems begin to appear, will flower ; yet their flowers will not be fo large, nor will their roots be near fo good af¬ ter, as thofe which vtere removed before they fent forth frefli fibres. When thefe roots come over, they ftiould be planted in pots filled with frefli, light, fandy earth,mixed with a little very rotten dung, and placed in a warm litua- tion, obferving now and then to refrefh the earth with water: but by no means let them have too much wet* which would rot their roots, efpeeially before they come up. About the middle of September, fuch of the roots as are ftrong enough to flower will begin to ftiow the bud of their flower-ftem r therefore thefe pots ought to be removed into a fituation where they may have the benefit of the fun, and be flickered from ftrong winds., When the flowers begin to open, the pots ftiould be removed under {belter, to prevent injury from too much wet.—After the flowers are decayed, the green leaves will begin to fhoot forth in length * and, if {belter-* ed from fevere cold, will continue growing all win¬ ter : but they muft have as much free air as pofiible in mild weather, and are to be covered only in great rains or frofts. For this purpofe, a common hot-bed frame is the moft proper {belter for them ; the glaffes of which may be taken off every day in dry open wea¬ ther, which will encourage the leaves to grow ftrong and broad. The roots ftrould be tranfplanted every fourth or fifth year, toward the end of June or begin¬ ning of July-; the offsets alfo fliould be taken off and planted in pots, w'here in three years time they-will produce flowers. The other fpecies of the amaryllis may eafilybe raifed by taking care to {belter them in a. ftove from the winter’s cold. AMARYNTHUS (anc. geog.), a hamlet of Ere- tsias, in the. ifland of Euboea, about feven ftadia diftant fifim its walls. Here Diana, was worihipped by an i-7 ] A M A annual folemnity, at which thofe of Caryftus aflifted ; Amafia hence the title of the goddefs was Amcv ynthis, and A- , U . r 0 ■' Amazon:: maryjia. , AMASIA (anc. geog.), now Marpurg, a city in the landgraviate of Heffe, on the Lahn. According: to others, it is Embden in Weftphalia. Amasia, an ancient town of Turkey, in Natolia, remarkable for the birth of Strabo the geographer. It is the refidence of a bafttaw, and gives its name to the province it ftands in, where there are the beft wines and the beft fruits in Natolia. It is feated near the ri¬ ver Iris or Cafalmack; and was anciently the refidence: of the kings of Cappadocia. E. Long. 36. 10. ’ N. Lat. 39. 33. Amasia, the name of the northern divifion of Lef- fer Afia, lying on the fouth fliore of the Euxine fea in- Natolia. It takes its name from Amafia the capital, , mentioned in the preceding article. A.MASONIA, in botany: A genus of the angio- fpermia order, belonging to the didynamia clafs of plants ; the characters of which are: The calyx is a- tripartite pnonophyllous perianthium, bell-fhaped and- perfiftent: The torolla is monopetalous and tubular; the border quinquefid, expanding, and fmall: The /la¬ mina confift of four filaments longer than the corolla the antherae oval and incumbent: Thepijlillum has an- ovate germen ; the ftylus the length of the ftamina; the ftigmata two, acute :. There is no pericarpium : The feed is an ovate unilocular nut, the length of the calyx. AMATHUS, a very ancient town in' the fouth of Cyprus (Strabo, Ptolemy) : .fo called from Amathus the founder; or, according to others, from Amath, a Phoenician town facred to Venus, with a very ancient temple of Adonis and Venus : and hence Venus is de¬ nominated Amathufia (Tacitus); According to Ovid* it was a place rich in copper-ore, and where the in habitants became Cer^/?^, or . horned. Now called Limiffoi, Amathus (anc. geog.), a town of the tribe of Gad, beyond Jordan ; but whether at a greater or lefs diilance from it, is not fo eafy to determine- Eufebius places ; it in the Lower Penea ; Reland, in Ramoth-Gilead. Gabinius,. proconful of Syria, eftabliftied five juridical conventions in Judea ; two of which were on the. other fide Jordan ; one at. Gadara, the. other at. Amathus (Jofephus). AMATORII musculii, in anatomy, a term fome- times ufed for the obliquus fuperior and obliquus infe¬ rior mufcles of the eye, as thefe mufcles affift in ogling or drawing the eye fideways. AMATRICE, a city of the kingdom of Naples, in the farther Abruzzo, upon the confines of the pope’s territories, and the marquifate of Ancona. . AMAUROSIS, in medicine, a deprivation of fight, the eye remaining fair and feemin’gly unaffe&ed. A perfedl amaurofis is when the blindnefs is total; when there is ftill a power of diftinguiftiing light from dark- nefs, the difeafe is called by M. de St Ives an impetfefl amaurojtu There is a periodical fort which comes on inftantaneoufly, continues for hours, or days, and then difappears. Mr Hey, furgeon at Leeds, mentions fe- veral cafes of patients afflifted with the amaurofis who were relieved by being eledtrified. AMAZONIA, or the country of the American A M A [51 Amazonia. Amazons, is fituate between 50 and 70 degrees of ' weft longitude'; and between the equator and 15 de¬ grees of fouth latitude; being bounded on the foutli by La Plata, on the weft by Peru, on the north by the province of Terra Firma, and on the eaft by Brazil. With refpecft to the Amazons faid to have given name to this territory, they have been reprefented as governed and led to war only by their queen. No men were fuffered to live among them; though thofe of Lome neighbouring nations were fuffered to vifit them, at a certain feafon, for the fake of procreation. The females iffuing from this commerce were bred up with care, and inftrufted in what relates to war and govern¬ ment ; as to the males, they were fent away into the country of their fathers. But no fuch nation is at .prefent to be found, any more than the giants and ca- nibals mentioned by the firft adventurers thither. Amazonia is generally a flat region, abounding in '•woods, lakes, rivers, bogs, and moraffes. The chief river, and one of the largeft in the world, is that call¬ ed the river of Amazons, or the Orellana, which is formed by two large rivers, the one riling in the pro¬ vince of Quito, a little fouth of the equator, in 73 degrees of weft longitude, and the other, named Xauxa, rifing in the lake of Bourbon, near the Andes, in ten degrees of fouth latitude. Thofe two rivers uniting on the confines of Peru and Amazonia, in three de¬ grees odd minutes of fouth latitude, affume the name of Amazon ; whence running eaftward upwards of 200 miles, and afterwards inclining to the north, they fall into the Atlantic ocean by 84 channels, which in the rainy feafon overflow the adjacent country. Befides the two ftreams mentioned, a multitude of others, both on the north and fouth fide, contribute to the formation of this extraordinary river. As it runs almoft acrofs the broadeft part of South America, it is computed to be between four and five thoufand miles in length, inclu¬ ding all its windings. Its channel from Junta de los Reyos, about 60 degrees from its head, to the river Maranhon, is from one to two leagues broad ; it then widens from three to four, and becomes gradually broader as it approaches the ocean. Between the places laft mentioned, its depth is from five to ten fathom ; but from Maranhon to Rio Negro it increafes to 20 fathom ; after which it is fometimes 30, and fometimes 50 fathoms, or more, till it comes near the end of its courfe. It has no fand-banks, nor does the ftiore ftielve fo as to render it dangerous for veffels. The manetu and tortoife abound both upon the banks of this and the other rivers ; and the filhermen muft be upon their guard againft the crocodiles, alligators, and water-fer- pents, which alfo fwarm here. The air, as in the countries under the fame parallel, is obferved to be nearly as cool under the equator as about the tropics, on account of the rains continuing longer, and the Iky in that feafon being clouded. Be¬ fides, an eafterly wind fets from the Atlantic up the river fo ftrong, that veffels are carried by it againft the ftream. The produce of the country is Indian corn and the caffavi root, of which they make flour and bread ; to¬ bacco, cotton, fugar, farfaparilla, yams, potatoes, and ether roots. They have alfo plenty of venifon, fifti, and fowl. Among the latter are vaft flocks of parrots 8 ] A M A of all colours, the flefh of which ferves for food and Amazonia^ the feathers for ornament. All the trees here are ever- Amazons.^ greens; and fruits, flowers, and herbage, are in per- v fedtion all the year round. The principal fruits are cocoa-nuts, ananas or pine-apples, guavas, bananas, and fuch others as are ufually found between the tro¬ pics. The foreft and timber trees are cedar, Brazil wood, oak, ebony, logwood, iron-wood, fo called from its weight and hardnefs, and feveral forts of dyeing wood. The natives are of the common ftature, with good features, a copper complexion, black eyes and hair. It is computed that there are of them about 150 dif¬ ferent tribes or nations, and the villages are fo nume¬ rous as to be within call of one another. Among thofe the Homagues, a people near the head of the river, are famous for their cotton manufactures; the Jurines, who live between five and ten degrees of latitude, for their joiners works ; and the Wrofiffares for their earthen ware. The Topinambes, who inhabit a large ifland in the river, are remarkable for their ftrength. Some of thofe nations frequently make war upon each other. Their armour confifts of darts, javelins, bows and ar¬ rows, and they wear targets of cane, or filh-lkin. They make flaves of their prifoners, whom they otherwife ufe very well. Every tribe is governed by its refpective chief or king, the marks of whofe dignity are a crown of parrots feathers, a chain of lions teeth or claws hung round his neck, or girt about his waitt, and a wooden fword, which he carries in his hand. Moft of thofe nations, except the Homagues, go naked. The men thruft pieces of cane through their ears and under-lips, as well as through the Ikin of the pudenda. At the griftle of their nofes they alfo hang glafs beads, which wag to and fro when they fpeak. They are fuch Ikilful markfmen, that they will flioot fifti as they fwim ; and what they catch they eat with¬ out either bread or fait. They worfhip images, which they always carry with them on their expeditions ; but they neither have temples nor any order of priefts; and permit both polygamy and concubinage. The country affords neither gold nor lilver mines; only a fmall quantity of the former is found in the ri¬ vulets which fall into the Amazon near its fources in Peru. While the Spaniards imagined that it contained thofe metals, they made great efforts from Peru to re¬ duce this territory to fubjeCtion ; till being at length undeceived, they abandoned the defign. AMAZONS, in antiquity, a nation of female war¬ riors, who founded an empire in Afia Minor, upon the river Thermodoon, along the coafts of the Black Sea. They are faid to have formed a ftate out of which men were excluded. What commerce they had with that fex, was only with ftrangers; they killed all their male children ; and they cut off the right breafts of their fe¬ males, to make them more fit for the combat. From which laft circumltance it is, that they are fuppofed to take their name, viz. from the privative «, and mamma, “ breaft.” But Dr Bryant, in his Analyfis of Ancient Mythology, explodes this account as fa¬ bulous ; and obferves, that they were in general Cu- thite colonies from Egypt and Syria, who formed fet- tlements in different countries, and that they derived their name from zon, the “ fun,” which was the na¬ tional objedl of worfhip. Vol. iii. p. 463.—It has in¬ deed A M A [ 5 Amazons, deed been controverted even among ancient writers, " v whether ever there really were fuch a nation as that of the Amazons. Strabo, Palasphatus, and others, deny it. On the contrary, Herodotus, Paufanius, Diodo¬ rus Siculus, Trogus Pompeius, Juftin, Pliny, Mela, Plutarch, &c. exprefsly affert it. M. Petit, a French phyfician, publilhed a Latin dif- fertation in 1685, to prove that there was really a na¬ tion of Amazons; it contains abundance of curious in¬ quiries, relating to their habit, their arms, the cities built by them, See. Others of the moderns alfo main¬ tain, that there exiftence is fufficiently proved by the teftimony of fuch of the hiftorians of antiquity as are moft worthy of credit; by the monuments which many of them have mentioned; and by medals, fome of which are ftill remaining; and that there is not the leaft room to believe that what is faid of them is fabulous. The Amazons are mentioned by the moft ancient of the Greek writers. In the, third book of the Iliad, Homer reprefents Priam fpeaking of himfelf as ha¬ ving been prefent, in the earlier part of his life, in a battle with the Amazons: and fome of them after¬ wards came to the affiftance of that prince during the fiege of Troy. The Amazons are particularly mentioned by Hero¬ dotus. That hiftorian informs us, that the Grecians fought a battle with the Amazons on the river Ther- modoon, and defeated them. After their vieftory, they carried off all the Amazons they could take alive, in three (hips. But whilft they were out at fea, thefe Amazons confpired againft the men, and killed them all. Having, however, no knowledge of navigation, nor any Ikill in the ufe of the rudder, fails, or oars, they were driven by wind and tide till they arrived at the precipices of the lake Mssotis, in the territories of the Scythians, Here the Amazons went afhore, and marching into the country, feized and mounted the firft horfes they met with, and began to plunder the inhabitants. The Scythians at firft conceived them to be men ; but after they had had Ikirmifhes with them, and taken fome prifoners, they difeovered them to be women. They were then unwilling to carry on hoftilities againft them; and by degrees a number of the young Scythians formed connexions with them, and’ were delirous that thefe gentle dames fhould live with them as wives, and be incorporated with the reft of the Scythians. The Amazons agreed to continue their connexion with the Scythian hufbands, but refufed to affociate with the reft of the inhabitants of the coun¬ try, and efpecially with the women of it. They af¬ terwards prevailed upon their hufbands to retire to Sar- matia, where they fettled. “ Hence,” fays Herodo¬ tus, “ the wives of the Sarmatians ftill continue their ancient way of living. They hunt on horfeback in the company of their hufbands, and fomedmes alone. They march with their armies, and wear the fame dfefs with the men. The Sarmatians ufe the Scythian language, but corrupted from tire beginning,, becaufe the Ama¬ zons never learned to fpeak correXly. Their marriages are attended with this circumftance: no virgin is per¬ mitted to marry till- {he has killed an enemy in the field; fo that, fome always grow old before they can. qualify themfelves as the law requires.” Diodorus Siculus fays, “ There was formerly a na¬ tion, who dwelt near the river Thermodoon, which was '■9 ] A M A fubjeXed to the government of women, and in which Amazons, the women, like men, managed all the military affairs. v—^ Among thefe female warriors, it is faid, was one who excelled the reft in ftrength and valour. She affembled together an army of women, whom fhe trained up in military difeipline, and fubdued fome of the neighbour¬ ing nations, Afterwards, having by her valour in- creafed her fame, fhe led her army againft the reft; and being fuccefsful, Ihe was fo puffed up, that fhe fty- led herfelf the daughter of Mars, and ordered the men to fpin wool, and do the work of the women within doors. She alfo made laws, by which the women were enjoined to go to the wars, and the men to be kept at home in a fervile ftate, and employed in the meaneft offices. They alfo debilitated the arms and thighs of thofe male children wLo were born to them, that they might be thereby rendered unfit for war. They (ear¬ ed the right breafts of their girls, that they might be no hinderance to them in fighting: from whence they derived the name of Amazons. Their queen, having become extremely eminent for flcill and knowledge in military affaix-s, at length built a large city at the mouth of the river Thermodoon, and adorned it with a magnificent palace. In her enterprizes fhe exaXly adhered to military difeipline and good order ; and fhe added to her empire all the adjoining nations, even to the river Tanais. Having; performed thefe exploits, fhe at laft ended her days like a hero, falling in a bat¬ tle, in which fhe had fought courageoufly. She was fucceeded in the kingdom by her daughter, who imi¬ tated the valour of her mother, and in fome exploits excelled her. She caufed the girls from their very in¬ fancy to be exercifed in hunting, and to be daily train¬ ed up in military exercifes. She inftituted folemn fe- ftivals and facrifices to Mars and Diana, which were named Tauropoli, She afterwards carried her arms beyond the river Tanais, and fubdued all the people of thofe regions, even unto Thrace Returning then with a great quantity of fpoils into her own kingdom, fhe caufed magnificent temples to be ereXed to the deities before mentioned; and fhe gained the love of her fubjeXs by her mild and gentle government. She afterwards undertook an. expedition againft thofe who were on the other fide of the river, and fubjeXed to her dominion a great part of Afia, extending her arms as far as Syria.” Diodorus alfo mentions another race of Amazons who dwelt in Africa ; and whom he fpeaks of as being of greater antiquity than thofe who lived near the ri¬ ver Thermodoon.. “ In the weftern parts of Lybia,” fays he, “ upon the borders of thofe traXs that are habitable, there was anciently a nation under the go¬ vernment of women, and whofe manners and mode of living were altogether different from ours. It was the cuftom for thefe women to manage all military affairs ; and for a certain time, during which they preferved their virginity, they went out^as foldiers into the field. After fome years employed in this manner, when the time appointed for this purpofe was expired, they affo- ciated themfelves with men, in order to obtain children. But the magiftracy, and all public, offices, they kept entirely in their own hands. The men, as the women are with us, were employed in houfehold affairs, fub- mitting themfelves wholly to the authority of their, wives. They were not permitted to take any part in military/ A M A [ 520 ] A M A Amazons, military affairs, or to have any command, or any pub- i;c authority, which might have any tendency to en¬ courage them to call off the yoke of their wives. As foon as any child was born, it was delivered to the fa¬ ther, to be fed with milk or fuch other food as was fuitable to its age. If females were born, they feared their breafts, that they might not be burdenfome to them when they grew up ; for they confidered them as great hindrances in fighting.” Juftinian reprefents the Amazonian republic to have taken its rife in Scythia. The Scythians had a great part of Alia under their dominion upwards of 400 years, till they were conquered by Ninus, the founder of the Affyrian empire. After his death, which hap¬ pened about 1150 years before the Chriftian sera, and that of Semiramis and their fon Ninias, Ilinus and Sco- lopites, princes of the royal blood of Scythia, were dri¬ ven from their country by other princes, who like them afpired to the crown. They departed with their wives, children, and friends; and being followed by a great number of young people of both fexes, they paffed in¬ to Afiatic Sarmatia, beyond mount Camaffus, where they formed an eftablilhment, fupplying themfelves with the riches they wanted, by making excurfions into the countries bordering on the Euxine Sea. The people of thofe countries, exafperated by the incurfions of ■their hew neighbours, united, furprifed, and maffacred the men. The women then refolving to revenge their death, and at the fame time to provide for their own fecurity, refolved to form a new kind of government, to choofe a queen, ena6l laws, and maintain themfelves, without men, even againft the men themfelves. This defign was not fo very furprifing as at firil fight appears : for the greateft number of the girls among the Scythians had been inured to the fame exercifes as the boys ; to draw the bow, to throw the javelin, to manage other arms ; to riding, hunting, and even the painful labours that feem referved for men ; and many of them, as- a- mong the Sarmatians, accompanied the men in war. Hence they had no fooner formed their refolution, than they prepared to execute it, and exercifed themfelves in all military operations. They foon fecured the peace¬ able poffeffion of the country ; and not content with Ihowing their neighbours that all their efforts to drive them thence or fubdue them were ineffectual, they made war upon them, and extended their own frontiers. They had hitherto made ufe of the inftruftions and af- fiftance of a few men that remained in the country; but finding at length that they could Hand their ground, and aggrandize themfelves, without them, they killed all thofe whom flight or chance had faved from the fury of the Sarmatians, and for ever renounced marriage, which they now confidered as an infupportable flavery. But as they could only fecure the duration of their new kingdom by propagation, they made a law to go e- very year to the frontiers, to invite the men to come to them; to deliver themfelves up to their embraces, without choice on their part, or the leaft attachment; and to leave them as foon as they were pregnant. All thofe whom age rendered fit for propagation, and were willing to ferve the ftate by breeding girls, did not go at the fame time in fearch of men: for in order to ob¬ tain a right to promote the multiplication of the fpe- cies, they mull firft have contributed to its deffrudlion; No 13. 4 nor was any thought worthy of giving birth to chil* Amazons, dren till (he had killed three men. <——y—j If from this commerce they brought forth girls, they educated them; but with refpeft to the boys, if we may believe Jullin, they ftrangled them at the moment of their birth: according to Diodorus Siculus, they twilled their legs and arms, fo as to render them unfit for military exercifes; but Quintus Curtius, Philo- ftratus, and Jordarus, fay, that the lefs favage fent them to their fathers. It is probable, that at firll, when their fury againft the men was carried to the greateft height, they killed the boys : that when this fury abated, and moll of the mothers were filled with horror at depriving the little creatures of the lives they had juft received from them, they fulfilled the firft duties of a mother; but, to prevent their caufing a revolution in the ftate, maim¬ ed them in fuch a manner as to render them incapable of war, and employed them in the mean offices which thefe warlike women thought beneath them: in Ihort, that, when their conquefts had confirmed their power, their ferocity fubfiding, they entered into political en¬ gagements with their neighbours; and the number of the males they had preferred becoming burthenfome, they, at the delire of thofe who rendered them preg¬ nant, fent them the boys, and continued Hill to keep the girls. As foon as the age of the girls permitted, they took away the right breaft, that they might draw the bow with the greater force. The common opinion is, that they burnt that breaft, by applying to it, at eight years of age, a hot brazen inftrument, which infenfibly dried up the fibres and glands: fome think that they did not make ufe of fo much ceremony, but that when the part was formed they got rid of it by amputation : fome, again, with much greater probability, affert, that they employed no violent meafures; but, by a continual comprelfion of that part from infancy, prevented its growth, at leaft fo far as to hinder its ever being in¬ commodious in war. Plutarch, treating of the Amazons in his life of The- feus, confiders the accounts which had been preferved concerning them as partly fabulous and partly true. He gives fome account of a battle which had been fought between the Athenians and the Amazons at A- thens; and he relates fome particulars of this battle which had been recorded by an ancient writer named Clidemus. He fays, “ That the left wing of the A- mazons moved towards the place which is yet called Amazonium, and the right to a place called Pryx, near Chryfa; upon which the Athenians, iffuing from be¬ hind the temple of the mules, fell upon them ; and that this is true, the graves of thofe that were llain, to be feen in the ftreets that lead to the gate Piraiea, by the temple of the hero Chalcodue, are a 1'ufficient proof. And here it was that the Athenians were routed, and lhamefufly turned their backs to women, as far as to the temple of the Furies. But frelh fupplies coming in from Palladium, Ardettus, and Lyceum, charged their right wung, and beat them back into their very tents; in which aftion a great number of the Ama¬ zons were flain.” In another place he fays, “ It ap« pears that the paffage of the Amazons through Thef- faly was not without oppofition ; for there .are yet to be feen many of their fepulchres near Scotufsea and Cy- nocephalse.” And in his life of Pompey, fpeaking of A M A Amazons the Amazons, Plutarch fays, “ They Idhabit thofe parts ' af mount Caucafus that look towards the Hyrcanian fea (not bordering upon the Albanians, for the terri- tories of the Getaz and the Leges lie betwixt): and with thefe people do they yearly, for two months only, accompany and cohabit,: bed and board, near the river Thermodoon. A fter that they retire to their own ha¬ bitations, and live alone all the reft of the year.” Quintus Curtius fays, “ The nation of the Amazons is fituated upon the borders of Hyrcania, inhabiting the plains of Thei-mifcyra, near the river Thermodoon. Their queen was named Thaleftris, and fhe had under her fubjeftion all the country that lies between mount Caucafus and the river Phafis. This queen came out of her dominions, in confequence of an ardent defire Ihe had conceived to fee Alexander; and being advanced near the place where he was, ftie previoufly fent mef- fengers to acquaint him, that the queen was come to have the fatisfaftion of feeing and converfing with him. Having obtained permiffion to vifit him, ihe advanced with 300 of her Amazons, leaving the reft of her troops behind. As foon as fhe came within fight of the king,- flie leaped from her horfe, holding two javelins in her right hand. The apparel of the Amazons does not cover all the body ; for their left fide is naked down to the ftomach, nor do the flcirts of their garments, which they tie up in a knot, reach below their knees. They preferve their left breaft entire, that they may be able to fuckle their female offspring ; and they cut off and fear their right, that they may draw their bows, and caft their darts, with the greater eafe. Thaleftris looked at the king with an undaunted countenance, and narrowly examined his perfon ; which did not, ac¬ cording to her ideas, come up to the fame of his great exploits : For the barbarians have a great veneration for a majeftic perfon, efteeming thofe only to be capable of performing great actions, on whom nature has confer¬ red a dignified appearance. The king having allied her whether fhe had any thing to defire of him, the replied, without fcruple or hefitation, that fhe was come with a view to have children by him, fhe being worthy to bring him heirs to his dominions. Their offspring, if of the female fex, fhe would retain herfelf; and if of the male fex, it fhould be delivered tp Alexander. He then afked her, whether fhe would accompany him in his wars ? But this fhe declined, alleging, That fhe had left nobody to take care of her kingdom. She conti¬ nued to folicit Alexander, that he would not fend her back without conforming to her wifhes; twit it was not till after a delay of 13 days that he complied. She then returned to her own kingdom. Juftin alfo repeatedly mentions this vifit of Thaleftris to Alexander; and in one place he fays, that fhe made a march of 25 days, in order to obtain this meeting with him. The interview between Alexander and Thaleftris is likewife mentioned by Diodoms Si¬ culus. The learned Goropius, as he is quoted by Dr Petit, laments, in very pathetic terms, the hard fate of Thaleftris, who was obliged to travel fo many miles, and to encounter many hardfhips, in order to procure this interview with the Macedonian prince ; and, from the circumftancea, is led to confider the whole account as incredible. But Dr Petit, with equal-erudition, with equal eloquence, and with fuperior force of reafoning, at length determines, that her journey was not founded Vol. I. Part II. A M A upon irrational principles, and that full credit is due to Amazons, thofe grave and venerable hiftorians by whom this tranf- * v ‘ a&ion has been recorded. The Amazons are reprefented as being armed with bows and arrows, with javelins, and alfo with an axe of a particular conftruftion, which was denominated the axe of the Amazons. According to the elder Pliny, this axe was invented by Penthifilea, one of their queens. On many ancient medals are reprefentations of the Amazons, armed with thefe axes. They are alfo faid to have had bucklers in the fhape of a half-moon. The Amazons are mentioned by many other ancient authors befides thofe which have been enumerated; and if any credit be due to the accounts concerning them, they fubfifted through feveral ages. They are reprefented as having rendered themfelves extremely formidable ; as having founded cities, enlarged the" boundaries of their dominions, and conquered feveral other nations. That at any period there fhould have been women, who, without the afliftance of men, built cities and governed them, raifed armies and commanded them, adminiftered public affairs, and extended their domi¬ nion by arms, is undoubtedly fo contrary to all that we have feen and known of human affairs, as to appear in a very great degree incredible ; but that women may have exifted fufficiently robuft and fufficiently coura¬ geous to have engaged in warlike enterprifes, and even to have been fuccefsful in them, is certainly not im- poffible, however contrary to the ufual courfe of things. In fupport of this fide of the queftion, it may be urged, that women who have been early trained to warlike exercifes, to hunting, and to an hard and laborious mode of living, may be rendered more ftrong, and ca¬ pable of more vigorous exertions, than men who have led indolent, delicate, and luxurious lives, and who have feldom been expofed- even to the inclemencies of the weather. The limbs of women, as well as of men, are ftrengthened and rendered more robuft by frequent and laborious exercife. A Ration of women, therefore,- brought up and difeiplined as the ancient Amazons are- reprefented to have been, would be fuperior to an equal number of effeminate men; though they, might be much inferior to an equal number of hardy men train¬ ed up and difeiplined in the fame manner. That much of what is faid of the Amazons is fabu¬ lous, there can be no reafonable doubt; but it does not therefore follow, that the whole is without foun¬ dation. The ancient medals and monuments on which they are reprefented are very numerous, as are alfo the teftimonies of ancient writers. It feems not rational to fuppofe that all this originated in fiftion, though it may be much blended with it. The Abbe Guyon fpeaks of the hiftory of the Amazons as having been regarded by many perfons as fabulous, “ rather from prejudice than from any real.and folid examination and it muft be acknowledged, that the arguments in favour of their exiftence, from ancient hiftory, and from ancient monuments, are extremely powerful. The faft feems to be, that truth and fiftion have been blended in the narrations concerning thefe ancient heroines. Inftances of heroifm in women have occafionally oc¬ curred in modern times, fomewhat refembling that of the ancient Amazons. The times and the manners of chivalry in particular, by bringing great enterprifes, 5 3 U bold [ 521 ] A M A Amazons, bold adventures, and extravagant heroifm, into fafhion, v infpired the women with the fame tafte. The women, in confequence of the prevailing paflion, rvere now feen in the middle of camps and of armies. They quitted the foft and tender inclinations, and the deli¬ cate offices of their own fex, for the toils and the toil- fome occupation of ours. During the crufades, ani¬ mated by the double enthufiafm of religion and of va¬ lour, they often performed the mod romantic exploits; obtained indulgences on the field of battle, and died with arms in their hands, by the fide of their lovers or of their huffiands. In Europe, the women attacked and defended for¬ tifications ; princeffes commanded their armies,, and obtained victories. Such was the celebrated Joan de Montfort, difputing for her duchy of Bretagne, and fighting herfelf. Such was that ftill more celebrated Margaret of Anjou, aftive and intrepid general and foldier, whofe genius fupported a long time a feeble hulband; which taught him to conquer; which repla¬ ced him upon the throne; which twice relieved him from prifon ; and, oppreffed by fortune and by rebels, which did not bend till after file had decided in perfon twelve battles. The warlike fpirit among the women, confiftent with ages of barbarifm, when every thing is impetuous becaufe nothing is fixed, and when all excefs is the ex- cefs of force, continued in Europe upwards of 400 years, flowing itfelf from time to time, and always in the middle of convulfions or on the eve of great revo¬ lutions. But there were asras and countries in which that fpirit appeared with particular luftre. Such were the difjilays it made in the 15th and 16th centuries in Hungary, and in the iflandsof the Archipelago and the Mediterranean when they were invaded by the Turks. Among the ftriking inftances of Amazonian condudl in modern ladies, may be mentioned that of Jane of Belleville, widow of Monf. de Cliffon, who was be¬ headed at Paris in the year 1343, on a fufpicion of carrying on a correfpondence with England and the Count de Montfort. This lady, filled with grief for the death of her late hufband, and exafperated at the ill treatment which ffie confidered him as having recei¬ ved, fent off “ her fon fecretly to London ; and when her apprehenfions were removed with refpeft to him, ffie fold her jewels, fitted out three ffiips, and put to fea, to revenge the death of her huffiand upon all the French with whom ffie ffiould meet. This new cor- fair made feveral defcents upon Normandy, where ffie ftormed caftles ; and the inhabitants of that province were fpeftators more than once, whilft their 1 villages were all in a blaze, of one of the fineft women in Eu¬ rope, with a fword in one hand and a torch in the other, urging the carnage, and eyeing with pleafure all the horrors of war.” We read in Mezeray, under the article of the Croi- fade, preached by St Bernard in the year 1147, “ That many women did not content themfelves with taking the crofs, but that they alfo took up arms to defend it, and compofed fquadrons of females, wffiich render¬ ed credible all that has been faid of the prowefs of the Amazons.” In the year 1590, the League party obtained fome troops from the king of Spain. Upon the news of their being difembarked, Barri de St Aunez, Henry XV.’s governor at Leucate, ffit out to communicate a A M A fcheme to the Duke de Montmorenci, commander in that province. He was taken in his way by fome of the troops of the League, who were alfo upon their march with the Spaniards towards Leucate. They were perfuaded, that by thus having the governor in their hands the gates of that place would be immedi¬ ately opened to them, or at leaft would not hold out long. But Conftantia de Cecelli, his wife, after ha¬ ving affembled the garrifon, put herfelf fo refolutely at their head, pike in hand, that ffie infpired the weakeffi with courage ; and the befiegers were repulfed where- ever they prefented themfelves. Shame and their great lofs having rendered them defperate, they fent a mef- fage to this courageous woman, acquainting her, that if (lie continued to defend herfelf they would hang her huffiand. She replied with tears in her eyes, “ I have riches in abundance: I have offered them, and I do ftill offer them, for his ranfom ; but I would not igno- minioufiy purchafe a life which he would reproach me with, and which he would be affiamed to enjoy. I will not diffionour him by treafon againft my king and country.” The befiegers having made a freffi attack without fuccefs, put her huffiand to death, and raifed the fiege. Henry IV. afterwards fent to this lady the brevet of governefs of Leucate, with the reverfion for her fon. The famous Maid of Orleans, alfo, is an example known to every reader. The Abbe Arnaud, in his Memoirs, fpeaks of a Countefs of St Balmont, who ufed to take the field with her huffiand and fight by his fide. She fent fe¬ veral Spaniffi prifoners of her taking to Marffial Feu- quiers; and what is not a little extraordinary, this A- mazon at home wras all affability and fweetnefs, and gave herfelf up to reading and acts of piety. Dr Johnfon feems to have given fome credit to the accounts wffiich have been tranfmitted down to us con¬ cerning the ancient Amazons; and he has endeavoured to ffiow, that we ought not haftily to reject ancient hiftorical narrations becaufe they contain fails repug¬ nant to modern manners, and exhibit feenes to which nothing now occurring bears a refemblance. “ Of what we know not (fays he), we can only judge by what we know. Every novelty appears more wonder¬ ful as it is more remote from any thing with which ex¬ perience or teftimony have hitherto acquainted us; and if it paffes farther, beyond the notions that we have been accuftomed to form, it becomes at laft incredible. We feldom confider, that human knowledge is very narrow ; that national manners are formed by chance ; that uncommon conjunctures of caufes produce rare effeits ; or that what is impoffible at one time or place may yet happen in another. It is always eafier to de¬ ny than to enquire. To refufe credit confers for a moment an appearance of fuperiority which every little mind is tempted to affume, when it may be gained fo cheaply as by withdrawing attention from evidence, and declining the fatigue of comparing probabilities. Many relations of travellers have been flighted as fabulous, till more frequent voyages have confirmed their veracity; and it may reafonably be imagined, that many ancient hiftorians are unjuftly fufpeCted of falfe- hood, becaufe our own times afford nothing that re- fembles what they tell. Few narratives will either to men or women appear more incredible than the hifto- ries of the Amazons; of female nations, of whofe con- ftitution [' 522 ] A M B [ 523 3 A M B Amazons 'ftitution it was the eflential and fundamental law, to Amba exclu<^e men from aH participation either of public ■ ' . affairs or domeftic bufincfs; where female armies march¬ ed under female captains, female farmers gathered the harveft, female partners danced together, and female wits diverted one another. Yet feveral ages of anti¬ quity have tranfmitted accounts of the Amazons of Caufacus; and of the Amazons of America, who have given their name to the greatefl river in the world, Condamine lately found fuch memorials as can be ex- pefted among erratic and unlettered nations; where events are recorded only by tradition, and new fwarms fettling in the country from time to time confufe and efface all traces of former times.” No author has taken fo much pains upon this fub- jeft as Dr Petit. But, in the courfe of his work, he has given it as his opinion, that there is great difficul¬ ty in governing ■ the women even at prefent, though they are unarmed and unpra&ifed in the art of war. After all his elaborate inquiries and difcuffions, there¬ fore, this learned writer might probably think,, that it is not an evil of the firlt magnitude that the race of Amazons now ceafes to exift. Rouffeau fays, “ The empire of the woman is an empire of foftnefs, of addrefs, of complacency. Her commands are careffes, her menaces are tears.” But the empire of the Amazons was certainly an empire of a very different kind. Upon the whole, we may con¬ clude with Dr Johnfon : “ The chara&er of the an¬ cient Amazons was rather terrible than lovely. The hand could not be very delicate that was only employed in drawing the bow and brandifhing the battle-axe. Their power was maintained by cruelty, their courage was deformed by ferocity; and their example only ffiows, that men and women live bell together.” Amazons (the river of), in America. See Ama¬ zonia. Amazonian Habit, in antiquity, denotes a drefs fornred in imitation of the Amazons. Marcia, the fa¬ mous concubine of the emperor Commodus, had the appellation of Amazonian, becaufe ffie charmed him moil in a habit of this kind. Hence alfo that prince himfelf engaged in combat in the amphitheatre in an Amazonian habit; and of all titles the Amazonius was one of thofe h‘e moft delighted in.—In honour either of the gallant or his miilrefs, the month December was alfo denominated Amazonius—Some alfo apply Amazonian habit to the hunting-drefs worn by many ladies among us. AMBA, an Abyffinian or Ethiopic word, fignify- ing a rock. The Abyffinians give names to each of their rocks, as Amba-Dorho, the rock of a hen, 8cc. Some of thefe rocks are faid to have the name of Aorni; and are of fuch a flupendous height, that the Alps and Pyrenees are but low hills in comparifon of them. A- mongfl the mountains, and even frequently in the plains, of this country, arife deep and craggy rocks of various forms, feme refembling towers, others pyramids, &c. fo perpendicular and fmooth on the fides, that they feem to be works of art; infomueh, that men, cattle, &c. are craned up by the help of ladders and ropes : and yet the tops of thefe rocks are covered with woods, mea¬ dows, fountains, fiffiponds, &c. which very copioufly fupply the animals feated thereon with all the conve¬ niences of life. The mod remarkable of thefe rocks is called Amba- Gejhen, It is prodigioufly deep, in the form of a cadle built of free done, and almod impreg- Ambaeht nable. Its fummit is about half a Portuguefe league jl in breadth, and the circumference at the bottom about 1‘ half a day’s journey. The afeent at fird is eafy ; but w—y—, .grows aftervyards fo deep, that the Abaffine oxen, which will otherwife clamber like goats, mud be craned up, and let down with ropes. Here the princes of the blood were formerly confined, in low cottages amongd dij-ubs and wild cedars, with an allowance barely fufficient to keep them alive. There is, according to Kircher, in this country, a rock fo curioufly hollowed by nature, that at a didance it refembles a looking-glafs; and op- pofite to this another, on the top of which nothing can be fo foftly whifpered but it may be heard a great way off. Between many of thefe rocks and mountains are vad abyffes, which appear very dreadful to the eye. AMBACHT, in topography, denotes a kind of jurifdidlion or territory, the poffeffor whereof has the adminidration of judice both va alto zsiiS. bafib; ox oi what is called in the Scots law a power of pit and gal¬ lows, i. e. a power of drowning and hanging.— In fome ancient writers, ambacht is particularly ufed for the jurifdidlion, government, or chief magillracy of a city. The word is very ancient, though ufed origi¬ nally in a fenfe fomewhat different. Ennius calls a mercenary, or flave hired for money, ambaftus ; and Caefar gives the fame appellation to a kind of depend¬ ents among the Gauls, who, without being Haves, were attached to the fervice of great lords. AMBAGES. See Circumlocution. AMBARVALIA, in antiquity, a ceremony among the Romans, when, in order to procure from the gods an happy harved, they condudled the vidlims thrice round the corn-fields in proceffion, before facrificing *kie.rs\.~ Amhat valia were either of a private or public nature : the private were performed by the mader of a family ; and the public by the prieds who officiated at the folemnity,calledfrah es ovules. Theprayer preferred on this occafion, the formula of which we have in Cato de Re Rujlica, cap. cxlii. was called carmen ambervale. At thefe feads they facrificed to Ceres a fow, a dieep, and a bull or heifer, whence they took the name of fuovetaurilia. The method of celebrating them was, to lead a vi6lim round the fields, while the peafants accompanied it, and one of their number, crowned with oak, hymned forth the praifes of Ceres, in verfes com- pofed on purpofe. This fedival was celebrated twice a-year; at the end of January, according to fome, or in April, according to others; and for the fecond time,. in the month of July. AMBASSADOR, or Embassador, a.public mini- der fent from one. foverei-gn prince, as a reprefentative of his perfon to another. Ambaffadors are either ordinary or extraordinary. Ambaffador in ordinary, is he who condantly refides in the court of another prince, to maintain a good un- derdauding', and look to the intered of his mader. Till about two hundred years ago, ambaffadors in or¬ dinary were not heard of: all, till then, were ambaf¬ fadors extraordinary; that is, fuch as are fent on fome particular occafion, and who retire as foon as the affair is difpatched. By the law of nations, none under the quality of a fovereign prince can fend or receive an ambaffador. Ait Athens, ambaffadors mounted the pulpit of the public 3 U 2. ©ratorSj A M B [ 524 ] A M B Ambe, orators, and there opened their commiffion, acquaint- ■Amber. jng the people with their errand. At Rome, they were " introduced to the fenate, and delivered their commiffions to the fathers. Ambafladors (hould never attend any public folemnir ties, as marriages, funerals, &c. unlefs their mailers have fome intereft therein: nor mull they go into mourn¬ ing on any occalions of their own, becaufe they repre- fent the perfon of their prince. By the civil law, the moveable goods of an ambalfador, which are accounted an acceffion to his perfon, cannot be feized on, neither as a pledge, nor for payment of a debt, nor by order or execution of judgment, nor by the king’s or Hate’s leave where he refides, as fome conceive ; for all actions ought to be far from an ambaffador, as well that which toucheth his necelfaries, as his perfon : if, therefore, he hath contracted any debt, he is to be called upon kind¬ ly ; and if he refufes, then letters of' requell are to go to his mailer. Nor can any of the ambaffador’s dome- flic fervants that are regiftered in the fecretaries of Hate’s office be arrelled in perfon or goods ; if they are, the procefs lhall be void, and the parties fueing out and executing it lhall fuffer and be liable to fuch penalties and corporal punilhipent as the lord chancellor or ei¬ ther of the chief jullices lhall think fit to infliCt. Yet ambaffadors cannot be defended when they commit any thing againll that Hate, or the perfon of the prince, with whom they refide; and if they are guilty of treafon, felony, &c. or any other crime againll the law of na¬ tions, theylofe the privilege of an ambaffador, and may be fubjeft to punilhment as private aliens. AMBE, in furgery, the name of an inllrument for reducing diflocated bones. In anatomy, a term for the fuperficial jutting out of a bone. AMBER (Succinum), in natural hillory, a folid, hard, femipellucid, bituminous fubftance of a parti¬ cular nature, of ufe in medicine and in feveral of the arts. It has been called amhra by the Arabians, and ekttrum by the Greeks. Amber has been of great repute in the world from the earlielt times. Many years before Chrilt it was in elleem as a medicine ; and Plato, Ariftotle, Hero¬ dotus, HEfchylus, and others, have commended its vir¬ tues. In the times of the Romans it became in high elleem as a gem ; and in the luxurious reign of Nero, immenfe quantities of it were brought to Rome, and ufed for ornamenting works of various kinds. The moll remarkable property of this fubftance is, that, when rubbed, it draws or attracts other bodies to it: and this, it is obferved, it does, even to thofe fubftances which the ancients thought it had an anti¬ pathy to; as oily bodies, drops of water, human fweat, &c. Add, that by the friCtion it is brought to yield light pretty copioully in the dark; whence it is rec¬ koned among the native phofphori. The propertywhich amber pofTelfes ofattrafting light bodies, was very anciently obferved. Thales of Miletus, 600 years before Chrift, concluded from hence that it was animated. But the firft perfon who exprefsly men¬ tions this fubftance, is Theophrallus, about the year 300 before Chrift. The attractive property of amber is Kkewife occafionally taken notice of by Pliny, and Other later naturalills, particularly by Galfendus, Ke- nelm Digby, and Sir Thomas Brown ; but it was ge- nerally apprehended that this quality was peculiar to amber and jet, and perhaps agate, till Gilbert publilhed Amber, his treat!fe De Magneto, in the year 1600. From nteKTpev, the Greek name for amber, is derived the term Eleftricity,which is now veryextenfively applied not only to the power of attracting light bodies inherent in am¬ ber, but to other fimilar powers, and their various ef¬ fects, in whatever bodies they refide, or to whatever bodies they-may be communicated. Amber a (fumes all figures in the ground ; that of a pear, an almond, a pea, &c. In amber there have been laid to be letters found very well formed j and even He¬ brew and Arabic charaCters.—Within fome pieces, leaves, infeCts, &c.’have likewife been found included ; which feems to indicate, either that the amber was ori¬ ginally in a fluid Hate, or that having been expofed to the fun, it was once foftened, and rendered fufceptible of the leaves, infeCts, &c. which came in its way. The latter of thefe fuppofitions feems the more agreeable to the phenomenon, b’ecaufe thofe infeCts, &c. are never found in the centre of the pieces of amber, but always near the furface. It is obferved by the inhabitants of thofe places where, amber is produced, that all animals, whether terreftrial, aerial, or acquatic, are extremely fond of it, and that pieces of it are frequently found in their excrements. The bodies of infeCts, found bu¬ ried in amber, are viewed with- admiration by all the world ; but of the moft remarkable of thefe, many are to be fufpeCted as counterfeit, the ’great price at which beautiful fpecimens of this kind fell, having tempted ingenious cheats to introduce animal bodies in fuch artful manners into feemingly whole pieces of amber, that it is not eafy to deteH the fraud. Of thofe infeCts which have been originally inclofed in amber, fome are plainly feen. to have llruggled hard for their liberty, and even to have left their limbs be¬ hind them in the attempt; it being no unufual thing to fee, in a mafs of amber that contains a (lout, beetle, the animal wanting one, or perhaps two of its legs ; and thofe legs left in dilferent places, nearer that part of the mafs from which it has travelled. This alfo may account for the common accident of finding legs, or wings of flies, without the reft of their bodies, in pieces of amber; the infeCts having, when entangled in the yet foft and vifeid matter, efcaped, at the expence of leaving thofe limbs behind them. Drops of clear water are fometimes alfo preferved in amber. Thefe have doubtlefs been received into it while foft, and pre¬ ferved by its hardening round them. Beautiful leaves of a pinnated HruClure, refembling fome of the ferns, or maidenhairs, have been found in fome pieces ; but thefe are rare, and the fpecimens of great value. Mi¬ neral fubftances are alfo found at times lodged in maf- fes of amber. Some of the pompous collections of the German princes boaft of fpecimens of native gold and filver in mafies of, amber; but as there are many fub¬ ftances of the marcafite, and other kinds, that have all the glittering appearance of gold and filver, it is not to be too hailily concluded that thefe metals are really lodged in thefe beds of amber. Iron is found in vari¬ ous (hapes immerfed in amber; and as it is often feen eroded, and fometimes in the ftate of vitriol, it is not. impoffible but that copper, and the other metals, may be alfo fometimes immerfed in it in the fame Hate: hence the bluilh and greenilh colours, frequently found in the recent pieces of amber, may be owing, like the particles A M B [ 525 ] A M B the gems, by their denfe texture, always retain their colours, this lighter and more lax bitumen ufually lo- fes what it gets of this kind, by keeping fome time. Small pebbles, grains of fand, arid fragments of other ftones, are not unfrequently alfo found • immerfed in amber. Naturalifts have been greatly divided as to the ori¬ gin of this fubftance, and what clafs of bodies it be¬ longs to; fome referring it to the vegetable, others to the mineral, and fome even to the animal kingdom. Pliny defcribes it as a reiinous juice, oozing from “ aged pines and firs (others fay from poplars, where- “ of there are whole forefts on the coafts of Sweden), •“ and difcharged thence into the fea, where, undergo- “ ing fome alteration, it is thrown, in this form, upon “ the (hores of Pruffia, which lie very low : he adds, f( that it was hence the ancients gave it the denomi- “ nation fuccinum; ivomfuccus, juice.” Some fuppofe amber a compound fubftanee. Pruf¬ fia, fay they, and the other countries which produce amber, are moiftened with a bituminous juice, which mixing with the vitriolic falts abounding in thofe pla¬ ces, the points of thofe falts fix its fluidity, whence it congeals ; and the refult of that congelation makes what we call amber ; which is more or lefs pure, tran- fparent, and firm, as thofe parts of fait and bitumen are more or lefs pure, and are mixed in this or that pro¬ portion. Mr Brydone, in his tour to Sicily and Malta, fays, that the river Gearetta, formerly celebrated by the poets under the name of Simetus, throws up near its mouth great quantities of ambe'r. He mentions alfo a kind of artificial amber, not uncommon there, made, as he was told, from copal, but very different from the natural. According to Plartman, amber is formed of a bitu¬ men, mixed with vitriol and other falts. But though this were allowed him in regard to the foflile amber, many difpute whether the fea-amber be fo produced. It is, however, apparent, that all amber is of the fame origin, and probably that which is found in the fea has been waflied thither out of the cliffs ; though Hartman thinks it very pofiible, that fome of it may be formed in the earth under the fea, and be waihed up thence. The fea-amber is ufually finer to the eye than the foflile ; but the reafon is, that it is divefted of that coarfe coat with which the other is covered while in the earth. Upon the whole, it feems generally agreed upon, that amber is a true bitumen of foffile origin. — In a late volume of the Journal de Phyfiqae, however, we find it afferted by Dr Girtanner to be an animal pro- du£t, a fort of honey or wax formed by a fpecies of large ant called by Linnaeus formica tufa. Thefe ants, our author informs us, inhabit the old pine forefts, where they fometimes form hills about fix feet in dia¬ meter ; and it is generally in thefe ancient forefts, or in places where they have been, that fofiile amber is found. This fubftance is not hard as that which is ta¬ ken up in the fea at Pruflia, and which is well known to naturalifts. It has the confiftence of honey or of half melted wax, hut it is of a yellow colour like com¬ mon amber; it gives the fame product by chemical analyfis, and it hardens like the other when it is fuf- fered to remain fome time in a folution of common fait. This accounts for the infedls that are fo often found inclofed in it. Among thefe infefts ants are al¬ ways the moft: prevailing; which tends farther, Mr Girtahner thinks, to the confirmation of his hypothe- fis. Amber then, in his opinion, is nothing but a ve¬ getable oil rendered concrete by the acid of ants, juft as wax is nothing but an oil hardened by the acid of bees; a facft inconteftably proved, we are told, fince Mr Metherie has been able to make artificial wax by mixing oil of olives with the nitrous acid, and which wax is not to be diftinguiftred from the natural. There are feveral indications which difcover where amber is to be found. The furface of the earth is there covered with a foft fcaly ftone ; and vitriol in particu¬ lar always abounds there, which is fometimes found white, fometimes reduced into a matter, like melted glafs, and'fometimes figured like petrified wood. Amber of the fineft kind has been found in Eng¬ land. It is frequently thrown on the fhores of York- fhire, and many other places, and found even in our clay-pits; the pits dug for tile-clay, between Tyburn and Kenfington gravel-pits, and that behind St George’s Hofpital at Hyde-park corner, have afforded fine fpe- cimens. Poland, Silefia, and Bohemia, are famous for the amber dug up there at this time. Germany affords great quantities of amber, as well dug up from the bowels of the earth, as toffed about on the ftiores of the fea and rivers there. Saxony, Mifnia, and Sweden, and many other places in this tra£t of Europe, abound with it. Denmark has afforded, at different times, fe¬ veral quantities of foffile amber ; and the ftiores of the Baltic abound with itv But the countries lyirig on the Baltic afford it in the greateft abundance of all ; and of thefe the moft plentiful country is Pruffia, and the next is Pomerania. Pruffia was, as early as the times of The- odoric the Goth, famous for amber j for this fubftance coming into great repute with this prince, fome natives of Pruffia, who were about his court, offered their fcr- vice to go to their own country, where that fubftance, theyfaid,was produced, and bring back great ftores of it. They accordingly did fo ; and from this time Pruffia had the honour to be called the Country of Amber, in - Head of Italy, which had before undefervedly that title. This article alone brings kis Pruffian Majefty a revenue of 26,000 dollars annually. The amber of Pruffia is not only found on the fea-coafts, but in digging; and though that of Pomerania is generally brought from the ftiores, yet people who dig, on different occafions, in the very heart of the country, at times find amber. Junker defcribes, after Neumann, the Pruffian amber- mines, which are the richeft known.—Firft, at the fur- face of the earth, is found a ftratum of fand. Imme¬ diately under this fand is a bed of clay, filled with fmali flints of about an inch diameter each. Under this clay lies a ftratum of black earth, or turf, filled with foffile wood, half decompofed, and bituminous ; this ftratum is extended upon a bank of minerals, containing little metal, ^except iron, which are confequently pyrites. Laftly, under this bed the amber is found, feattered about in pieces, or fometimes accumulated in heaps. Amber has a fubacrid refinous tafte, and fragrant aromatic fmell, efpecially when diffolved. It differs from the other bituminous fubftances in this, that it yields by diftillation a volatile acid fait, which none of the others do; otherwife it affords the fame fort of principles A M B [ 526 ] A M B principles as them, viz. an acid phlegm, an oil which gradually becomes thicker as the diftillation is conti¬ nued ; and when the operation is finilhed, there re¬ mains a black caput mortuum in the retort. — When boiled in water, it neither foftens, nor undergoes any fenfible alteration. Expofed to the fire in an open veffel, it melts into a black mafs very like a bitumen : It is partly foluble in fpirit of wine, and likewife in fome effential oils; but it is with difficulty that the expreffed ones are brought to aft upon it; the ftrong- er forts of fixed alkaline lixivia almoft totally dii- folve it. This fubftance is principally of two colours, white and yellow. The white is the moll efteemed for me¬ dicinal purpofes, as being the moft odoriferous, and containing the greatell quantity of volatile fait; tho’ the yellow is moft valued by thofe who manufafture beads and other toys with-it, by reafon of its tranfpa- rency.' Amber is the bafis of all varniffies, by folution in the ways defcribed under the article Varnish.' Amber, when it has once been melted, irrecoverably lofes its beauty and hardnefs. There have been fome, however, who pretended they had an art of melting fome fmall pieces of amber into a mafs, and conftitu- ting large ones of them : but this feems fuch anoth&r undertaking as the making of gold; all the trials that have yet been made by the moft curious experimenters, .proving, that the heat which is necelfary to melt am¬ ber, is fufficient to deftroy it. Phil. Tranf. N° 248. Could amber indeed be difiblved without impairing its tranfparency, or one large mafs be made of it by uniting feveral fmall ones, it is eafy to fee what would be the advantages of fuch a procefs. The art of em¬ balming might poffibly be alfo carried to a great height by this, if we could preferve the human corpfe in a tranfparent cafe of amber, as the bodies of flies, fpi- ders, gralhoppers, &c. are to a great perfeftion. Something of a fubftitute of this kind we have in fine rofin ; which being diffolved by heat, and the bodies of fmall animals feveral times dipped in it, they are thus coated with colophony, that in fome degree refembles amber; but this mult be kept from dull. Amber in fubftance has been much recommended as a nervous and cordial medicine ; and alleged to be ver-y efficacious in promoting the menftrual difcharge, aud the exclufion of the foetus and fecundines in la¬ bour: but as in its crude ftate it is quite infoluble by our juices, it certainly can have very little effeft on the animal fyftem, and therefore it is now feldom given in fubftance. The forms in which amber is prepared are, A tinfture, a fait, and an oil; the preparation and ufes of which arc defcribed in the proper place under the article Pharmacy. sl\ii)F.R-Tree, the Engliffi name of a fpecies of Anthospermum.

AMBERGREASE, Ambergrise, or Grey Am¬ ber, in natural hillory, is a folid, opake, afh-c«loured, 3 fatty, inflammable fubftance, variegated like marble, re¬ markably light, rugged and uneven in its furface, and has a fragrant odour when heated. It does not effer- vefce with acids ; it melts freely over the fire, into a kind of yellow rbfin ; and is hardly foluble in fpirit of wine. It is found fwimming upon the fea, or the fea-coaft, or in the fand near the fea-coaft ; efpecially in the At¬ lantic ocean, on the fea-coatt of Brafil, and that of Ma- dagafcar ; on the coaft of Africa, of the Eaft Indies, China, Japan, and the Molucca iflands; but moft of the ambergrife which is brought to England comes from the Bahama iflands, from Providence, &c. where k is found on the coaft. It is alfo fometimes found ia the abdomen of whales by the whale-fifliermen, always in lumps of various fhapes and fizes, weighing from half an ounce to an hundred and more pounds. The piece which the Dutch Eaft India Company bought from the king of Tydor, weighed 182 pounds. An American fiffierman from Antigua found fome years ago, about 52 leagues fouth-eaft from the Windward iflands, a piece of ambergrife in a whale, which weigh¬ ed about 130 pounds, and fold for 500 1. Sterling. There have been many different opinions concerning the origin of this fubftance. It has been fuppofed to be a foffile bitumen or naph¬ tha, exuding out of the bowels of the earth in a fluid form, and diftilling into the fea, where it hardens and floats on the furface. But having been frequently found in the belly of whales, it has by others been confidered as entirely an animal produftion. Clufius afferted it to be a phlegmatic recrement, or indurated indigeftible part of the food, collefted and found in the ftomach of the whale, in the fame man¬ ner as the bezoars are found in the ftomach of other animals. In an account communicated by Paul Dudley, Efq; in the 23d volume of the Philofophical Tranfaftions, the ambergife found in whales is reprefented as a kind of animal produft, like muflc, and caftoreum, &c. fe- creted and collefted in a peculiar bag or bladder, which is furnifhed with an excretory duft or canal, the fpout of which runs tapering into and through the length of the penis ; and that this bag, which lies juft over the teilicles, is almoft full of a deep orange-coloured liquor, not quite fo thick as oil, of the fame fmell as the balls of ambergrife, which float and fwim loofe in it: which colour and liquor may alfo be found .in the cabal of the penis; and that therefore ambergrife is never to be found in any female, but in the male only. But thefe circumftances are not only deftitute of truth, but alia contrary to the laws of the animal oeconomy : For, in the firft place, ambergrife is frequently found in females as well as males ; although that found in females is never in fuch large pieces, nor of fo good a quality, as what is found in males. Secondly, No perfon who has the leaft knowledge in anatomy or phyiiology, will e- ver believe that organifed bodies, fuch as the beaks of the Sepia, which are fo conftantly found in ambergrife taken out of the whale, can have been abforbed from the inteftines by the lafteals or lymphatics, and colleft¬ ed with the ambergrife in the precluded bag above- mentioned. Ktempfer, who has given us fo many other faithful accounts in natural hiftory, feems to come nearer the truth Amber- Amber- grcafe. A M B With with regard to the origin of ambergrife, when he fays, that it is. the dung of the whale ; and that the Japanefe, for this reafon, call it kufura noya«,i.e. whale’s dung. This account, however, though founded on ob- fervation, has never obtained credit, but has been con- fidered rather as a fabulous ftory, with which the Ja¬ panefe impofed upon him, who had himfelf no diredl obfervation to prove the fact. This matter, therefore, remained a fubjedt of great doubt; and it was generally thought to be more pro¬ bable, that ambergrife, after having been fwallowed, and fomehow or other changed in the ftomach and bowels of the whale, was found among its excrements. But the moft fatisfadtory account of the real origin of ambergrife, is that given by Dr Swediar in the 73d volume of the Philofophical Tranfadtions, art. 15, We are told by all writers on ambergrife, that fonle- times claws and beaks of birds, feathers of birds, parts of vegetables, fliells, fifh, and bones of fifh, are found in the middle of it, or varioufly mixed with it. Of a very large quantity of pieces, however, which theDodtor exa¬ mined, he found none that contained any fuch thing; though he allows, that fuch fubftances may fometimes be found in it: but in all the pieces of any confiderable fixe, whether found on the fea or in the whale, he con- ftantly found a confiderable quantity of black fpots, which, after the moll careful examination, appeared to be the beaks of the Sepia Ofiopodia; and thefe beaks, he thinks, might be the fubftances which have hitherto been always miftaken for claws or beaks of birds, or for Ihells. The prefence of thefe beaks in ambergrife proves e- vidently, that all ambergrife containing them is in its origin, or muft have been once, of a very foft or liquid nature, as otherwife thofe beaks could not fo conftant- ly be intermixed with it throughout its whole fubftance. That ambergrife is found either upon the fea and fea-coaft, or in the bowels of whales, is a matter of fadt univerfally credited. But it has never been examined into and determined,' whether the ambergrife found upon the fea and fea-coaft is the fame as that found in the whale, or whether they are different from one ano¬ ther ? Whether that found on the fea or fea-coaft has fome properties, or conftituent parts, which that found in the whale has not ? And laftly, Whether that found in the whale is fuperior or inferior in its qualities and value to the former ? It is likewife a matter of confequence to know, Whe¬ ther ambergrife is found in all kinds of whales, or only in a particular fpecies of them? Whether it isconftant- ly and always to be met with in thofe animals ? And, if fo, in what part of their body it is to be found ? All thefe queftions we find very fatisfadterily dif- cuffed by Dr Swediar. According to the beft information that he could ob¬ tain from feveral of the moft.intelligent perfons, em¬ ployed in the fpermaceti whale-filhery, and in procu¬ ring and felling ambergrife, it . appears, that this fub¬ ftance is fometimes found in the belly of the whale, but in that particular fpecies only which is called the. fpertnaceti whale, and which from its defcription and delineation appears to be the ParsETER Mactocephalus Linnaei. The New England fiftiermen, according to their ac¬ count, have long known that ambergrife is to he found [ 527 1 A M B in the fpermaceti whale ; and they are fo convinced of Araber- this fad!, that whenever they hear of a place where greafe. ^ ambergrife is found, they always conclude that the feas v in that part are frequented by this fpecies of whale. The perfons who are employed in the fpermaceti whale-fiftiery, confine their views to the Phyfeter ma- crocephalus. They look for ambergrife in all the fper¬ maceti whales they catch, but it feldom happens that they find any. Whenever they hook a fpermaceti whale, they obferve, that it conftantly not only vomits up whatever it has in its ftomach, but alfo generally difcharges its faeces at the fame time ; and if this latter circumftance takes place, they are generally difappoint- ed in finding ambergrife in its belly. But whenever they difcover a fpermaceti whale, male or female, which feems torpid and fickly, they are always pretty fure to find ambergrife, as the whale in this ftate feldom voids its faeces upon being hooked. They likewife generally meet with it in the dead fpermaceti whales, which they fometimes find floating on the fea. It is obferved alfo, that the whale, in which they find ambergrife, often, has a morbid protuberance ; or, as they exprefs it, a kind of gathering in the lower part of its belly, in which, if cut open, ambergrife is found. It is obfer¬ ved, that all thofe whales, in whofe bowels ambergrife is found, feem not only torpid and fick, but are alfo conftantly leaner than others; fo that, if we may judge from the conftant union of thefe two circumftances, it would feem that a larger colle&ion of ambergrife in the belly of the whale is a fource of difeafe, and probably fometimes the caufe of its death. As foon as they., hook a whale of this defcription, torpid, fickly, ema¬ ciated, or one that does not dung on .being hooked, they immediately either cut up the above-mentioned protuberance, if there be any, or they rip open its-, bowels from the orifice of the anus, and find the am¬ bergrife, fometimes in.one fometimes in different lumps, of generally from three to. twelve and more inches in diameter, and from one pound to twenty or thirty pounds in weight, at the diftance of two, but molt, frequently of about fix or feven feet from the anus, and never higher up in the inteftinal canalj which, accord-- ing to their defcription, is, in all. probability, the inte- ftinum caecum, hitherto miftaken for a peculiar bag made by nature for the fecretion and colle&ion of this , fingular fubftanpe.. That the part they cut open to - come at the ambergrife is no other than the inteftinal canal is certain, becaufe they conftantly begin their in- cifion at the anus, and.find the cavity everywhere filled with the fseces of the whale, which from their colour and fmell it is impoffible for them to miftake. The ambergrife found in the inteftinal canal is not fo hard as that which is found on the fea or fea-coaft, but foon grows hard in the air: when firft taken out it has nearly the.fame colour, and the fame difagreeable fmell, though not fo ftrong, as the more liquid dung of the whale has; but, on expofing it to the air, it by degrees not Only grows greyilh, and its furface is covered with a greyifli duft like old chocolate, but it alfo lofes its dif¬ agreeable fmell, and, when kept for a certain length of time, acquires the peculiar odour which is fo agreeable to moft people. The gentlemen the Do&or converfed with confeffed, that if they knew not from experience that ambergrife thus found, will in time acquire the above-mentioned, qua- - A M B [ 528 ] A M B qualities, they would by no means be able to diftinguifli ambergrife from hard indurated feces. This is fo true, that whenever a whale voids its feces upon being hook¬ ed, they look carefully to fee if they cannot difcover among the more liquid excrements (of which the whale difcharges feveral barrels) feme pieces floating on the fea, of a more compact fubftince than the relt ; thefe they take up and waih, knowing them to be amber¬ grife. In confidering whether there b| any material diffe¬ rence between ambergrife found upon the fea or fea- coafi:, and that found in the bowels or among the dung of the whale, the Doftor refutes the opinion, that all ambergrife found in whales is of an inferior quality, and therefore much lefs in price. Ambergrife, he ob- ferves, is only valued for its purity, lightnefs, compadf- nefs, colour, and fmell. There are pieces of amber¬ grife found on different coaffs, which are of a very in¬ ferior quality ; whereas there are often found in whales pieces of it of the firft value ; nay, feveral pieqes found in the fame whale, according to the above-mentioned qualities, are more or lefs valuable. All ambergrife found in whales has at fir ft when taken out of the in- teftines very near the fame fmell as the liquid excre¬ ments of that animal have ; it has then alfe nearly the fame blackifti colour: they find it in the whale feme- times quite hard, fometimes rather foftifli, but never fo liquid as the natural feces of that animal. And it is a matter of fa&, that, after being taken out and kept in the air, all ambergrife grows not only harder and whiter, but alfo lofes by degrees its fmell, and affumes fuch an agreeable one, as that in general has which is found fwimming upon the'fea ; therefore the goodnefs of ambergrife feems rather to depend on its age. By being accumulated after a certain length of time in the mteftinal canal, it feems even then to become of a whiter colour, and lefs ponderous, and acquire its agreeable fmell. The only reafon why ambergrife found floating on the fea generally poffeffes the above-mentioned qua¬ lities in a fuperior degree, is becaufe it is commonly older, and has been longer expofed to the air. It is more frequently found in males than females; the pieces found in females are in general fmaller, and thofe found in males feem conftantly to be larger and of a better quality ; and therefore the high price in proportion to the fize is not merely imaginary for the rarity-fake, but in feme refpeft well founded, becaufe fuch large pieces appear to be of a greater age, and poffefs the above- mentioned qualities in general in a higher degree of perfedtion than fmaller pieces. It is known, that the Sepia oftopodia, or cuttle-fifh, is the conftant and natural food of the fpermaceti whale, or Phyfeter macrocephalus. Of this the fifhers are fo well perfuaded, that whenever they difcover any recent relics of it fwimming on the fea, they conclude that a whale of this kind is, or has been, in that part. Another circumftance which corroborates the fact is, that the fpermaceti whale on being hooked generally vomits up feme remains of the Sepia. Hence it is eafy to account for the many beaks, or pieces of beaks, of the Sepia found in all ambergrife. The beak of the Sepia is a black horny fubftance, and therefore paffes undigefted through the ftomach into the inteftinal ca¬ nal, where it is mixed with the feces ; after which it is either evacuated with them, or if thefe latter be preter- N° 14. naturally retained, forms concretions with them, which Amber- render the animal fick and torpid, and produce an ob- , greafe‘ ftipation, which ends either in an abfcefs of the abdo- v men, as has been frequently obferved, or becomes fatal to the animal; whence in both the cafes, on the burft- ing of its belly, that hardened fubftance, known under the name of ambergrife, is found fwimming on the fea, or thrown upon the coaft. From the preceding account, and his having con¬ ftantly found the above-mentioned beaks of the Sepia in all pieces of ambergrife of any confiderable fize, Dr Swediar concludes with great probability, that all am¬ bergrife is generated in the bowels of the Phyfeter macro¬ cephalus, or fpermaceti whale ; and there mixed with the beaks of the Sepia oftopodia, which is the principal food of that whale. He therefore defines ambergrife to be the ,preternaturally hardened dung or feces of the Phyfeter macrocephalus, mixed with feme indigef- tible relics of its food. The ufe of ambergrife in Europe is now nearly con¬ fined to perfumery, though it has formerly been recom¬ mended in medicine by feveral eminent phyiicians. Hence the Effentia Ambrse Hoffmanni, Tin Aura Regia Cod. Parifini, Trochifei de Ambra Ph. Wurtemberg, &c. If we wifti to fee any medicinal effe&s from this fub¬ ftance, the Do&or obferves, we muft certainly not ex- peA them from two or three grains, but give rather as many fcruplesof it for a dofe : though even then, he thinks, there would not be reafon to expeA much ef- feA from it, as he had himfelf taken of pure unadul¬ terated ambergrife in powder 30 grains at once, with¬ out obferving the leaft fenfible effeA from it. A failor, however, who had the curiofity to try the effeA of re¬ cent ambergrife upon himfelf, took half an ounce of it melted upon the fire, and found it a good purgative; which proves that it is not quite an inert fubftance. In Afia and part of Africa ambergrife is not only ufed as a medicine and as a perfume ; but confiderable ufe is alfe made of it in cookery, by adding it to feveral difties as a fpice. A great quantity of it is alfo con¬ ftantly bought by the pilgrims who travel to Mecca ; probably to offer it there, and make ufe of it in fumi¬ gations, in the fame manner as frankincenfe is ufed in Catholic countries. The Turks make ufe of it as an aphrodifiac. Our perfumers add it to fcented pillars, candles, balls or bottles, ■ gloves, and hair-powder; and its effence is mixed with pomatums for the face and hands, either alone or mixed with mufk, &c. tho’ its fmell is to feme perfens extremely offenfive. Ambergrife may be'known to be genuine by its fra¬ grant fcent when a hot needle or pin is thruft into it, and its melting like fat of an uniform confiftence ; whereas the counterfeit will not yield fuch a fmell, nor prove of fuch a fat texture.—One thing, however, is very remarkable, that this drug, which is the moft fweet of all the perfumes, ftiould be capable of being refembled in fmell by a preparation of one of the moft odious of all (links. Mr Homberg found, that a vef- fel in which he had made a long digeftion of the hu¬ man feces, acquired a very ftrong and perfeA fmell of ambergrife, infomuch that any one would have thought a great quantity of effence of ambergrife had* been made in it. The perfume was fo ftrong and offenfive, that the veffel was forced to be removed out of the elaboratory.

AMBIDEXTER, a perfon who can ufe both hands with the fame facility, and for the fame purpofes, that the generality of people do their right hands.—As to the natural caufe of this faculty, fome, as Hcefer, attribute it to an extraordinary fupply of blood and fpirits from the heart and brain, which furnifh both hands with the neceffary ftrength and agility : others, as Nicholas Mafia, to an ereCt fituation of the heart, inclining neither to the right hand nor left ; and o- thers to the right and left fubclavian arteries being of the fame height and the fame diftance from the heart, by which the blood is propelled with equal force to both hands.—But thefe are only conje&ures, or rather chimeras. Many think, that, were it not for educa¬ tion and habit, all mankind would be ambidexters; and in faft, we frequently find nurfes obliged to be at a good deal of pains before they can bring children to forego the ufe of their left hands. How far it may be an advantage to be deprived of half our natural dex¬ terity, may be doubted. It is certain, there are in¬ finite occafions in life, when it would be better to have the equal ufe of both hands. Surgeons and oculifts are of neceflity obliged to be ambidexters; bleeding, &c. in the left-arm or left-ancle, and operations on the left-eye, cannot be well performed but with the left- hand.—Various inftances occur in hiftory, where the left-hand has been exercifed preferably to the right.
