GEOGRAPHTh that part of mixed Mathe- matics, which explains the State of the Earth, and of it's Parts, depending on Quantity, viz. it*s Figure, Place, Magnitude, and Motion, with the Celeftial Appearances, &'c. B Y fome it is taken in too limited a Senfe, for a bare Defcription ol the feveral Countries -, and by others too extenfively, who along with fuch a De- fcription would have their Political Conftitution. But the Authors who proceed thus are exculable, becaufe they do it only to excite and delight the Reader, who might other wife be the lefs attentive to a bare Enumeration and Defcription of the Coun- tries, without fome Knowledge of the Manners, and Cuftoms of the Inhabitants. 'The Divifwn of Geography, ^ W E divide Geography into General and Special, or Univerfal and Particular. Golnitziui fays. Geo- graphy is to be explained externally and internally ; but thefe Terms are improper, and ill chofen, Uni- verfal and Particular being much more pertinent. We call that Univerfal Geography which confiders the whole Earth in general, and explains it's Pro- perties without regard to particular Countries : But Special or Particular Geography defcribes the Confti- tution and Situation of each fingle Country by itfelf which is twofold, viz. Chorographical^ which de- fcribes Countries of a confiderable Extent ; or Topo- graphical^ which gives a View of fome place or fmall Tradl of the Earth. I N this Book, we fhall exhibit Univerfal Geogra- phy^ which may be divided into three Parts, Abfo- lute^ Relative, and Comparative.

THE Things which feem to be mofl: worthy of Obfervation in every Country are of three kinds, viz. Celejlial, Terrejlrial^ and Human. The Celefiial Pro- perties are fuch as affed: us by reafon of the apparent Motion of the Sun, and Stars. Thefe are eight in Number: i. The Ekvatioji of the Pole, or the Dif- tance of a Place from the Equator. 2. The Obliquity of the Diurnal Motion of the Stars above the Horizon of that Place. 3.

'The Rifing, Appearance, and Continuance, of the Stars above the Horizon. 7. The Stars that pafs thro' the Zenith of a Place. 8. The Celerity of the Motion with which, according to the Co- pernican Hypothefis, every place conflantly revolves. And according to Aftrologers a ninth Property may be added ; for they afllgn fome Country or other to every one of the twelve Signs of the Zodiac, and the Planets which are Lords of thefe Signs -, but fuch imaginary Qualities feem fuperflitious and vain to me ; nor do I perceive any reafonable Foundati- on for them {a). Thus far the Celeflial Properties. W E call thofe Terreftrial Properties that are ob- ferved in the Face of every Country ; which are ten in Number, t . The Limits and Bounds of each Country. 1.

I. of Vfiiverfal Geography. f THE third kind of Obfervations to be made in every Country, we call Humane becaufe they chiefly refpedl the Inhabitants of the Place -, and thefe are alio ten in Number. i. Their Stature, Shape, Colour, and the length of their Lives ; their Origin, Meat, and Drink. 2. Their Arts, and the Profits which arife from them \ with the Merchandife and Wares they barter with one another. 3, Their Virtues and Vices, Learning, Capacities, and Schools. 4. Their Ceremonies at Births, Marriages, and Fu~ ?ierals. 5. The Language which the Inhabitants ufe. 6. Their Political Gcverninen^. y . Their Religion and Church Government. 8. Their Cities and famous Places. 9. Their remarkable Hiflories. 10. Their famous Men, Artificers, and the Inventions, of the Natives. THESE are the three kinds of Occurrences to be explained in Special Geography j and tho' the lafl Sort leem not fo properly to belong to this Science, yet we are obliged to admit them for Cuftom fake, and the Information of the Reader. I N Univerfal Geography (which is the Subjedt of this Book) the abfolute Divifion of the Earth, and the Conftitution of it's Parts, will firft be exa- mined ', then the Celeftial Phenomena, in general, that are to be applied to their refpe<5live Countries, in Special Geography -, and laftly, there will follow in the Comparative Part fuch Confiderations as occur from comparing the Phasnomena of one Place with another. t The Principles of Geography, THE Principles from which Arguments are drawn for proving Propofitions in Geography are of three forts, i. Geometrical, Arithmetical, and Trigonometrical Propofitions. 2. Aftronomical Precepts and Theorems (tho* it may feem ftrange B 3 we 6 1h Abfohite Part S E c T. I. we Hiould hav^e Recourfe to the Celeflial Bodies, which are dillant from us fo many Millions of Miles, for underftanding the Nature of the Earth we inhabit). 3. Experience j becaufe the greateft Part of Geography, and chiefly the Special^ is founded only upon the Experience and Obferva- tions of thofe who have defcribed the feveral Coun- tries. The Order of Geography. THE Order we have thought mofl conve- nient to follow in General Geography, is already mentioned in the Divifion and Explication of it's Properties •, yet there remains a Doubt as to the Order to be obfcrved in explaining thefe Properties : viz. whether we fnould apply them to their relative Countries in which they are found, or refer the Couiicries themfelves to the Properties accounted for, in general. Arijlotle, in his iirft Book of A- nimals, moves the fame Doubt ; and argues at large, whether the Properties fliould be adjufted to the general Account of Animals, or the Animals ranked under the Account of their Properties. The like Difficulty occurs in other Parts of Philofophy. However we Ihall here firft explain fome general Properties ; and after apply them to their refpedive Countries. The Proof of Geography. I N proving Geographical Proportions we are to obfcrve •, that feveral Properties, and chiefly the Celeft:ial, are confirmed by proper Dcmonfl:ra- tions : But in Special Geography (excepting the Ce- IcflialsJ almoll every Thing is explained without Demonfl:ratIon ; being either grounded on Expe- rience and Obfcrvation, or on the Teitimony of our Chap. i. of U?iherfal Geography, j our Senfes : nor can they be proved by any other Means. For Science is taken either for that Know- ledge which is founded on things highly proba- ble •, or lor a certain Knowledge of I'hings which is gained by the force of Argument, or the Tefti- mony of Senfe •, or for that Knov/lcJge which a- rifes from Dcmonilraiion in a iu'ldl Senfe, fuch as is found in Geometry, Arithmetic, and other Ma- thematical Sciences ; excepting Chronology and Geography ; to both which the Name of Science, taken in the fecond Senfe, doth moft properly be- long. T H E R E are alfo feveral Propofitions proved, or rather expofed to view, by the artificial Ter- reftrial Globe, or by Geographical Maps ; moft of which might be confirmed by a ftri(5t Demonftrati- on ; tho' omitted on Account of the Incapacity of fome Readers. Other Propofitions cannot be lb well proved, yet are received as apparent Truths. Thus tho' we fuppofe all Places on the Globe, and in Maps, to be laid down in the fame Order as they really are on Earth ; neverthelefs in thefe Mat- ters we rather follow the Defcriptions that are given by Geographical Authors. Globes and Maps, in- deed, made from fuch Obfervations, ferve well enough for lUuftration, and the more cafy Com- prehenfion of the Thing. Ihe Origin of Geograph'j, THE Origin of Geography is not of late Date, nor was it brought into the World as it were at one Birth •, neither was it invented by one Man : but it's Foundations were laid many Ages ago. It is true, indeed, the old Geographers were employed only in defcribing particular Countries, either in whole, or in part. The Romans^ when they had overcome and fubdued any Province, ufed to ex- B 4 pofe 8 ^he Ahjolute Tart S e c t. L pofe the Chorograph^ thereof to the Speflators in their Triumphs delineated upon a liable, and Jlouriflied round with Picflures. There were alfo at Romc^ in the Portico of Luculhts, feveral Geographi- cal Tables expoled to public View. The Senate of Rojne, about one hundred Years before the Birth of Christ, lent Geographers and Surveyors into the fe- veral parts of the Earth, that they might meafure the whole -, tho' they fcarce vifited a twentieth Part of it. Neco^ alfo, King of Egrpt, many Ages be- fore Christ, commanded that the Extremities of jifrica fliould be diligently fcarched into •, which was performed by the Fbcenidans in the fpace of three Years. Darius commanded that the Mouths of the River Indus, and' the whole ytthiotic Sea, to the eallward, fliouId be diligently examined into. Alex- ander the Great, as Plin^ tells us, in his Afiatic Ex- pedition, carried along with him two Geographers, Dicgenes2ind Beta, to meafure and delineate to him his Journies ; from whole Journals and Obfervations the Geographers of fucceeding Ages borrowed many Things. And tho' the fludy of all other Arts was almoit abolifhed by the Wars, Geography and For- ■/4ification were improved thereby. NEVERTHELESS the Geography of the Antients v/as very imperfed:, and commonly full of falfe Relations ; becaufe they knew little or nothing of thofe Places of the Earth which are of moil Con- fequence to be known -, or at leaft they had no cer- tain Experience about them. For, I. 2\\ America V/as entirely unknown to them. 2. So were there- motefl Northern Countries. 3. The South Ccnti- vent and the Country of Magellan. 4. They knew not that the World could be failed round, or that the Earth was furrounded by the Ocean, in an un- interrupted Continuity : Some indeed of the Anti- ents I confefs were of this Opinion, but I deny fhey I]ad any Certainty of it. 5. They knew not Chap. i. of V7therfal Geography. 9 that the horrid Zone was inhabited, by an almoft in- finite number of People. 6. They were ignorant of the true Meafure of the Earth, the' they writ a great deal on that fubjeft. 7. They did not think that Afrka could be failed round (b)^ becaufe the South Parts thereof were unknown to them. 8. Both the Greeks and Romans wanted true Defcripti- ons of the Countries remote from them, and have left us a great many forged and fabulous Stories, concerning the People that live in the Borders of Jfia, and thofe that inhabit the Northern parts of the Earth (c). 9. They were ignorant of the ge- neral Motion of the Sea, and the Diflerence of Cur- rents in particular Places, 10. The Grecians^ even Jrifiotlc himfelf, did not know the Reafon of the Ebbing and Flowing of the Sea, 1 1 . Few of them underftood the Variation of the Winds ; and the {b) It is likely the antient Egyptiatjs had fome Knowledge of the extream Parts of Africa, as appears from what Herodotus relates, ^iz.

In another Place there areafort of grinning Apilh People, born with long hairy Tails, and very fwift of Foot. From which Romantic ftories of PBiy, Sir J . Mande- fille took his lying Reports, of his meeting (in his T'ravels,) with thefe very People, and al- fo fome, in the TorridZone, that to guard themfelves againft the fcorching Heat of theSun, had one of their Feet fo large, that by lying on their backs, and holding it up againft the Sun, would fcreen them againft it's immoderate Heat ; with otlier the like whimfical Relations.

THERE are three Things that recommend the Scudy of Geography, i. It's Dignity ; and in that it greatly adorns Man, the Inhabitant of the Earth endowed with Reafon above all other Ani- mals, to underftand the Nature of Countries, and the ConlUtution of the Earth. 2. It is as well a plea- fant, as an innocent Recreation. 3. There is an ab- folute necefficy for the Knowledge of it j becaufe neither Divines, Phyficians, Lawyers, Hijlorians, nor other Men of Letters, can well proceed in their Studies, without interruption, unlefs they have fome Knowledge of Geography ; as it hath been obferved by others, and illuftrated by feveral Examples.

Of Divers Meafures. BECAUSE the ufe of Meafures is frequent in Geography, and fince divers Nations ufe dif- ferent Meafures, 'tis proper to premife fomewhat concerning them •, partly that the Reader may the better underftand the Writings of the antient Geo- graphers and Hiftorians ; and partly that he may compare together thofe in ufe at this Day. THE Length of a Foot is almoll univerfally made ufe of, tho' a Foot in one Place differs from that in another. Mathematicians frequent- ly meafure by the Rhinland Foot of Snellius, which he proves to be equal to the old Roman Foot. And becaufe Snellius was very diligent and accu- rate in meafuring the Earth, that Rhinland Foot C 4 of 24 '^be Ahjolute Fart Sect. I. of his is defervedly taken as a Standard for ar other Meafures (^). See half it's Length, iJPig. i.) A PERCH or Pole ought to confift of ten fuch Feet. But the Surveyors in liolla/id make 12 Feet a Rhinland Perch, and in Germany they com- pute 16 -, which is very incommodious in Calcula" tion. Snellius makes the Holland Mile equal to 1500 Rhinland Fetches (each Perch being 12 Foot) or iSoo Rhinland Feet. THESE two Meafures, a Perch and a Mile, arife from the repetition of a Foot •, but a Palm^ an Inch^ and a Barley-Corn^ (which are fometimes ufed in Holland) proceed from it's Divifion, An Inch is the twelfth Part of a Foot. A Palm is 4 Inches, A Barley. Corn is the fourth Part of an Inch. However it would be much better to divide the Foot into 10 Inches, and the Inch into 10 Subdivifions or Seconds, ^c. THESE are the Meafures now made ufe of by the Dutch in Geography. It remains that fome others be alfo taken Notice of ; viz. thofe of the Antients, whether Greeks, Romans., Perfians, Aigyp- tians ; and thofe alfo of later Times as of the 'Turks ^ Polanders., Germans., Mofcovites., Italians, Spaniards, French, and Englijh.

Heraclitus, that antient Philo- fopher, is laid to have been of their Opinion : tho* others fay, he fuppofed the Earth to be in the Shape ol: a Skitt, or Canoo, very much hollowed. But what is more ftrange Francis Patricius (a modern Philofopher of no fmall Repute in the laft Age) ftrcnuoufly endeavoured to prove, that the Earth was horizontally flretched out and plain under Foot. ^naxmander is faid by Peucerus to have fuppofed the Earth like a Cylinder -, tho' that is not fo pro- bable, becaufe he tried to meafurc it, and alfo in- vented a fort of a Dial at hacedcsmon^ upon which the Top of the Gnomon by it's Sliadow marked out the Days of the Equinoxes, and Soljltces : which fhewed him to have been tolerably fkilled in J/lro- r.omy, confidering the Time he lived in. Leucippus alio thought the Earth to be in the Shape of a Drum. Thefe with a great many other abfurd Opinions, are by Arijhlle and others attributed to the Antients : of which fee Arijlotle Lib. ii.

Let ft; pqp [Fig. 4.) be a cir- cular Sedlion of the Earth made by the Meridian, inch as it was thought to be formerly, and pp the Axis or Diameter joining the Poles, and t^q the Diameter of the Equator : then the oval Line JE P QJ*, defcribed upon the Diameter tE Q^and P P, will reprefent the Seftion or true Meridian Line, which for DiftiniElion fake is made hereto differ more from a Circle than it really ought to do j but in truth, the Proportion is as 692 to 689. So that the Line C Q_ meafuring the Altitude of the Earth at the Equator, exceeds C P the Altitnde at the Pole S5200 Paris Feet, or about 1 7 Miles. This Affair is well worthy to be traced to it's Original, and to be backed by a Demonftration, fo far as our Purpofe will permit.

T\it French made an Experi- ment about forty Years ago, fhewingthata Pendulum (which is a well known Inftrument for meafuring of Time) vibrates fo much the flower, by how m.uch the nearer it is brought to the Equator : that is, the Gravity, of Celerity of Defcent of tlae Pendulum, and of all other Bo- dies, is lefs in Countries ap- proaching the Equator than in Places near cither Pole. The two famous Philofophers New- ton and Huygens being excited by the Novelty of the Thing, and fearching more narrowly in to the Caufe of it, found thereby that the Earth muft have fome other Figure than what was known ; and alfo demonfbated that this Diminution of Weight doth naturally arifc from the Rotation of the Earth round it's Axis ; which Rotation, accord- ing to the Laws of circular Mo- tion, repels all heavy Bodies from the Axis of Motion : fo that this Motion being fwifter under the Equator than in Parts more remote, the Weight cf Bodies muft alfo be much lefs there than nearer the Poles. Therefore the Parts of the O- cean under the Equator being made lighter, and according to the Nature of all Fluids, preffed and forced on cither fide by the Waters nearer the Poles, they muft be raifed up to a greater Height, that fo they may better fupport and balance the greater Weight of the contiguous Wa- ters. Which mutual Libraticn is demonftrated upon Suppofi- tion of that Inequality of the Dis meters which we mentioned, above. The Figure of the Sea being refembled by the Lands adjacent, which are every v/here raifed above the Sea, the afore- faid Form muft be attributed to the whole terraqueous Globe.

Jurws Appendix. Dr Derhojn ( in his Phyfico. Theol. B. ii. C. I . Note [a) doth not feem to entertain any doubts concerning the terraqueous Globe, and the other Planets, being of a prolate fpheroidal Fi- gure; but he faith, Thataltho' lie hath often viewed Jupiter, and other Planets, with very good Glaffes, which he hath of 72 feet, and the Royal Society's Glafs of above 120 feet, yet he never could perceive them to be otberwifg than pcff<;6lly globu- lar. And he thinks it next to impoflible, to take an exadt mea- fure of the Polar and ^quatoreal Diameters, by reafon of the Smallnefs of theirapparent Dia- meters in a Micrometer, and their Motion all the timeofmea- furing them. And as to the Variation of the Vibrations of Pendulums, under the Line, and in the Northern and Southern Latitudes, he hath no doubt, but different Diilances from the Earth's Center, may caufe different Vibrations ; but yet he ihews, from good Expe- riments he made with Pendu- lums in the Air-Pump, that thofe Alterations might, in fome meafure, be from the Rarity and Denfity of the Air, in the different Zones. And I may add to Dr. Derhatns Experiments, the Lengthening of Iron Rods by Pleat, and their Shortening by Cold ; which 1 have found to be A-ery confidcrable, by ve- ry exa6t E.xperiments, Parts C H A p. 3 • rf Univerfal Geography. 3 i Parts ought to make up a globular Figure. 3. When, at the firft Creation the Waters were confufedly mixed with the Earth, it "was then without doubt moift and foft *, but the Figure of all moift and li-. quid Bodies is fpherical : and fo ought the Earth to remain after the ieparation of the moift Parts from the dry. I SAY, negleding thefe and fuch like Argu- ments, let us look out for better ; which are of three kinds. Of the firft there is only one deduced dprioriy as they call it : thofe of the other two kinds are de- monftrated a pojieriori ; or from Celeftial or Ter- reftrial Obfervations and Appearances. THE firft Argument is taken from the Nature of Water, and borrowed either from Ariftotle or Archie medes. Ariftotle in his fecond Book de Ccelo, chap. 5th, propofes it as his own, after this manner, (tho' it iz Jikely he borrowed it from fome Philofopher before him). If we take it for granted f fays he) that Wa- ter of it's own Nature tends always down to the moft concave or loweft Place •, it will neceflarily follow, that the Superficies of the Water is round or fpherical ; but that Place is moft concave that is neareft the Center of the Earth, therefore let there be drawn from the Center ^- two right Lines «^3 and «> ; and from /3 to 7 the Line ?>y •, to which from tt let fill the Perpendicular ctz. (^c) It is plain the Line a J" (Fig. 5.) is lefs than <*3 or ety^ and there- fore the Place <^ is lower and more concave then ^ or y ; therefore the Water muft flow downwards from /3 and y *till the Lines t:^, ay^ and a-J" are equal» that is, 'till aJ" becomes Ai equal to a.^, and cty 5 hence /3, £, and >- being in the Periphery of the fame Circle, muft make the true Superficies of the W^a- t^r of a round Figure. (f) EhcM lib, i. Prop. 1 8, THIS ^2 The Ahfolute Tart Se CT. H. THIS is ArijlotWs Demonftration, in whichjj befides the Incoherency of it, which might be eafi- ly amended, I obferve thefe greater Errors, i. He fuppofeth the Univerfe to have a certain Center. 2. That Places are higher or lower in refpefl to that Center. Now he who denies the fpherical Fi- gure of the Earth, will pcrhapsgrant neither of thefe Poftulata : Tho' the Univerfe may be eafily proved to have a Center, bccaufe the apparent Mo- tion of the fixed Stars obligeth us to fuppofe that they themfelves either revolve by a diurnal Motion, or that the Earth is turned about it's Center. If the Stars be really moved, then the Point about which they will revolve v^^ill certainly be the Center of the Univerfe. If the Earth ♦, then the middle Point round which it moves, may, in the Demonftration, be taken for Arijiotk^s central Point. But the chief Difficulty is in the fecond Suppofition ; viz. that Places are higher or lower in refped; of that Center ; becaufe he who will have the Superficies of the Earth to be a Plane, or fome other Figure, not round, will deny this Suppofition, and fay that Places appear higher or lower in refpccft of the horizontal Plane, perpendicular to which the Earth is infinitely extend- ed downwards ; or will perhaps explain the Decli- vity fome other way ; fo that the Argument would not be conclufive except it were firft granted that the Elevation of one Place above another is only in re- ipedt of fome Center, about which the Stars have their apparent Motion. And tho' this were true, and all other Notions of Declivity by which Water is deprefil'd were confuted, yet it could fcarcely be admitted for a Principle, becaufe it precarioufly fuppofes the Earth to be of a fpheric Figure, which is begging the Queftion. THEREFORE fome prefer Archmedes^s Demonftration (found in the firfi Book of his De Infi- dmt'ibm Humido) which is indeed more artificial than that C H A p. 3 • 9f "Univerfal Geography, % ^ that of Ariflotle -, yet labours under the fame Diffi- culties, in previoufly I'uppofing the Earth to beof'a fpheric Figure, to whofe Center the prefTure of the Water is made. But we are far from fuppofing that the divine Archimedes could be guilty of any falfe Reafoning ! No, his Defign in that Book was not to demoflrate the fpherical Figure of the Earth ffor then he had indeed begged the Queftion) but only to explain the Nature of Water and other Li- quids i in order to which he pre-fiippofes the Earth to be of a fpherical Figure, or to have a Center, to which all heavy Bodies in general tend •, and this he takes as a Principle before known and demonftrated from other Phsenomena : So that I wonder Clav'ws did not obferve this, who, in his Commentary upon Joannes de Sacro Bofco^ ufes this Demonftration of Archimedes for the fpheric Figure of the Earth : Sneliius^lfo does the fame in his Eratojlhenes Batavus. But it was AriJlotWs, Defign in the Place before cited to demonftrate the fpheric Figure of the Earth, Sea, and Heavens ; wherefore he could notaffume a Cen- ter to the Univerfe, or Earth, without being guilty of a manifeft Paralogifm. S O that this Argument taken from the Nature of Water, tho it be propofed be almoft all Authors, yet labours under fome Difficulties, which more learned Mathematicians have endeavoured to re- move, ifpoffible. I have myfelf fpent fome Time upon this Matter, and tryed feveral Methods, but could not bring them to bear. I was induced to attempt the Thing, becaufe it would be an elegant and unqueftionable Demonftration of the fpherical Figure of the Earth. THEREFORE waving this ; we fhall now propofe fome Arguments a pojierioriy taken firft , from celeftial Phaenomena. Let us conceive a Sec- tion made by a plane or a meridian Line fwhich is called the Line of Latitude) to pafs thro' a Place B, VOL. I, D or 34 ^'fj^ Abfolute Fart S e c T.

And fuppofe another Sedlion (or Luie of Longitude) {F'lg.o^,) to pafs thro' the fame Point B, perpendicular to the fcrrmer, and parallel to the Equator ; as E B F C. I fay thefe two Sei5lions or Lines on the Surface of the Earth may be proved to be circular. And it is a plain geometrical T'heot'em, that any Superficies whatever, when it is cut with perpendicular Planes, interfe6t- ing each other in one common Line or Axis, if the Lines produced on the Surface be circular, the Body can be no other than ipherical. THEREFORE if we can prove, that the two perpendicular Sedlions are circular, which pafs thro' any Point, B, taken at Pleafure ; we may alfo by the aforefaid Theorem conclude the Superficies of the Earth to be of a fphsrical Figure, and the Earth itfclf a globular Body. N O W it is proved from divers celeftial Phaeno- mena, that a Section made from one Pole to ano- ther, according to the Latitude of the Earth, is cir- cular. I. If in the Line ABCD, a Perfon go from any Point, as B, towards either Pole, as M , or the Star near it •, he will find that by equal Jour- nies he will equally approach nearer the Pole ; which would be impoffible if the Line he travelled in was not circular ; as is plainly fhewed by the artificial terrejirial Globe, 2.

Alfo the artificial Globe ^ which we make to reprefent the Earth, exhibits all thcfe Things as they really are on the Earth ; which would certainly, in fome Cafes, be different, except this was it's true Reprefentation.

Therefore Eratojlhenes (who attempted it next after him, and lived about 200 Years before Chrill ; being perfeftly fl^illcd in Menfuration, and other Parts of Mathematics) is juftly celebrated and efteemed by all, as the firft and moft accurate Mea- furer of the Earth. He difcovered the Perimeter of it to be about 250000 Furlongs ; or, as others fay, 252.000; which are, as P/i/7y tells us, 31.500.000 Roman Paces, equal to 3 1.500 Miles of 1000 Paces each. ST R ABO relates the Contents of three Books of Geography that had been writ by Eratojlhenes^ •which are now loft, thro' the Injury of Time. Cleo- medes alfo mentions the Method he ufed in meafur- ing the Earth -, which we fliall explain afterwardc. However, this Meafure o^ Eratojlhenes wViSyad^tdi by feveral Mathematicians (and firfb by Hipparchus about 100 Years after) to deviate fomething from the Truth : tlio' Hipparchus himfelf has not left us his Method of Menfuration •, but only added 25.000 Furlongs to Eratojlhenes^ % Perimeter. After him Pofidonius (an excellent pra6lical Aftronomer, and alfo well flcilled in Philofophy -, a little before Chrift, in the Time of Cicero and Pompef) fet about it, and found, by his Menfuration, the Circumference of the Earth to be 240.000 Furlongs, zs,Cleo7nedesit\h us. But Strabo differs from him, and fays it was 180.000 : whence there arofe great Doubts and Dif- putes about the Caufe of this Difference. It is true, Strabo's Method is delivered in few Words, and is in Fadl much nearer the Truth than the other : but becaufe Cleomedes both read and taught Pofidonius's Geography, we fhall explain his Method hereafter. NEVERTHELESS, the Dimenfions of Eratojlhenes were made ufe of by many; even 'till the Time of Ptolemy. And he, in the year of Chrift j44j ufed 180.000 Furlongs, as the Perimeter, and affirmed 44 ^b^ Ahfoliite Part Sect. II. affirmed it to be moft agreeable- to the Truth ; in- fomuch that this Invention was, by Theon^ afcribed to him. We gather alfo from the Writings of Ptole7n\^ that Marinus, a famous Geographer, by "whofe Writings he himfelf was very much inftrudt- ed, had attempted fomething in this Matter. PrOLEMT(\n Lib. i. Chap. 3, of his G^c- graphy) tells us, that he alfo had tried this Method, not the fame Way with his PredecefTors ; but in Places of different Meridians : tho' he does not tell us how much he found the Perimeter to be, but con- tents himfelf with the Meafure he had received from Marinus and his PredecelTors, viz. 180.000 Fur- longs. AFTERWARDS, when the Cultivation of Arts by degrees difappeared in Greece, nothing was done in this Bufinefs ', neither did the Romans trou- ble themfelves about it. BUT the jlrabs and Saracens having wrefted the Glory of Empire and Arts out of the Hands of the Grecians, did not negleft this Part of Mathe- matics. For (as Snellius tells us from Abulfeda, an Arabian Geographer, who flourifhed about the Year of Chrift 1300, and whofe Writings were pub- lifhed at Rome) about the 800 Year of the Chriftian jEra, Maimon King of Arabia, or Calif of Baby- lon, being a great Student in Mathmatics, com- manded Ptokmfs Great Conjlru^ion to be tranflated from the Greek into Arabic, which is, by the Ara- lians, called Ptolemy* s Abnagejl. This Maimon hav- ing fummoned together fcveral learned Mathemati- cians commanded them to fearch into the Earth's Pe- rimeter. For performing of which they made ufe of the Planes of Zinjan or Mefopotamia ; and mea- furing from North to South under the fame Meridian 'till they had decreafed the Elevation of the Pole one Degr. they found the length of their Journey to be 56 Miles, or ^6h; from whence we find the ; Perimeter C n A p. 4- rf TJniverfal Geography. 45 Perimeter of the Earth to be 20.160 Miles, or 20. 340, according to that Meafure. FROM that Time to this none were folicitous about folving the Problem. The j^rabs commonly Lifing the Dimenfions they had received from their Mathematicians •, and the Italians, when they beg-an toftudy Aftronomy, madeufe of P/o/d-w^'s Meafure, viz. 1 80.000 Furlongs (which make 2 1 .600 Italian Miles, c,. 4^00 German; fo that 60 of the former, and 1 5 of the latter was thought to make a Degree : but they ought to have reckoned 15s of the latter, becaufe 32 Furlongs nearly equal a German Mile ; thus the Periphery would be 5625 Germ. Miles). But about 80 Years ago Snellius, a famous Mathe- matician, and Profeffor at Leyden, obferving that the Perimeter of the Earth, commonly made ufe of by Mathematicians (or the length a Degree, vul- garly fuppofed 15 Dutch Miles), was quellionable, and founded upon no certain Demonltration ; hs thereupon applied himfelf with great Induftry to it's Menfuration, and happily finiflied it ; demonftra- ting the Magnitude of one Degree of the Earth's Pe- riphery to be 28.500 Perches (each containing 12 Rhinland Feet) or 19 Holland Miks -, and the wholc- Periphery to equal 6.840 Miles (reckoning 1.500 Perches, or 18.000 Rhinland Feet, to a Mile). WE thought fit to premife this fhort Hiftory of the Earth's Menfuration, that the Reader may per- ceive by what Induftry it hath been managed, and with what Difficulty effefled. Now we fliall treat of the different Methods of Menfuration, all found- ed upon the Difcovery of the 'Ed.nWsfpherical Figure, which we have proved in the preceding Chapter. Therefore, confidering it globular^ if it be cut by a Plane pafiing thro' the Center, the Section will be a great Circle of the Earth : if not thro' the Center, then the Se<5tion will be one of the leffer Circles. Alfo the Periphery of a great Circle upon the Surface of the Earthj 46 ^he Ahfolute Fart Sect. IL Earth, is it*s Circuit or Meafure round. Note^ This Periphery is divided (as all others are) into 360 Degr. and becaufe the Extent of the whole cannot be meafured at once, we folve the Problem by finding the Length of a Part (f iz, of i Degr. k Degr. l^c.) in known Meafures; which NecefTity often occurs ino- ther Problems.We alio frequently take the Periphery of the Earth to be a Meridian paffing thro* the Place of Obfervation, and the North or Pole-Star ; which is more eafy, and lefs fubjed to Error. 'The fir fl Method'^ ttfedhy the Arabians and others for meafurwg the Earth. LET our Horizon be y& H R S J ; then the Peri- meter of the Terredrial Meridian (which lies under, and is concentrical to, that in the Heavens abed) will be A BCD, (Fig. 6.) and R will be the Cen- ter of the Earth. Suppofe our Place of Obfervation at B, whofe Zenith is ^, and the Terreftrial Pole A lying under that in the Heavens a ^ then the Ele- vation of the Pole above our Horizon will be A H, or ah. Let us rake another Place in the fime Me- ridian A B CD under ab c d, as G, who.^e Zenith is g, and Horizon/F R T /. Now fuppofe the Ele- vation of the Pole to be accurately obferved in the Place B, viz. a h or A H •, and alfo in the Place G, viz. fa or F A. Take F A from H A and the Re- mainder is H F, equal to B G, the Arch intercepted between the two Places. Laftly, the Diftance B G equal to the Arch b g^ \>x.o be accurately meafured by fome known Meifure, as a Perch or a Mile.' Then by the Goldej^ Rule fay, as B G is to AB G C D, 360 Degr. fo is the known ' Ir.terval in Miles or Perches, to the Miles or Perches contained in the Periphery A B G C D : or as the Arch B G is to i Degr. fo are the Miles in the Diftance B G, to the Miles or Perches in i Degree. NOTE, C H A p. 4- <>f Vnherfal Geography, 47 NOTE, if you take the vulgar Computation of the Diftance B G, without meafuring it, then the Quan- tity of the Degree will be determined accordingly ; as I Dcgr. will equal 15 fuch JVIiles, as B G equals 10, i^c. Example, Let B be Amjlerdatn, where the Eleva- tion of the Pole AH or (2 Z) is 52 degr, 23 min. and let G be Schoonhoven, lying under the fime Meri- dian wkh Amfterdam, where the Elevation of the Pole A F or a/ is 51 degr 54 min, therefore FH or BG will be 29 min. but the Diftance betweea jimjlerda?n and Schoonhoven is gl Dutch Miles, or 13875 Rhinland Perches, 12 Foot each •, therefore as 29 7nin. is to 60 min. or i degr. fo is 97^ Miles to 19 Dutch Miles: therefore 19 Dutch Miles equal I degr. and 6.840 make 360, or the whole Peri- phery. O R if the Diftance B G be fuppofed jl German Miles feach equal to 1900 Rhinland Fcrchcs) it will be as 29 min. is to 60 min. fo is 7 4: to 15 of the fame German Miles, for a Degr. of which 5.400 make the v/hole Circumference- Thus the Elevation of the Pole at Prague is 50 degr. 6 7nin. and at Lincimn 48 degr. 1 6 min. the Difference B G is i degr. 50 min. and the Diftance is computed to be 26 German Miles i from whence the Periphery will be 5.105 Miles. The fecond Method, that of Eratofthenes. AGAIN, let there be two Places under the fame Meridian ; the one B, Alexandria in Egypt, where Eratofthenes, Keeper of the King's Library, Jived ; the other G, (Fig. 6.) the Town of Syene, a City in Egypt, under the Tropic of Cancer, and for that Reafon, chofen by Eratofthenes, whofe Di- ftance from Alexandria was computed 5000 Fur- longs. Let the Diftance of the Sun, at Noon, from the Zeniths, g and ^, of both Places be obfcrved 48 The Ahjblute Part S e c t. II. obferved by an Inftrument on the fame Solfti- tial Day, viz. the 21ft oijune-, when at Alexan- dria^ gb or G B equals fo Part of the Periphery by Obfervation (or 7 degr. 1 2 ptin.) but at Syene the Sun hath no Diftance from the Zenith at Noon, it being exa6lly vertical that Day. So that the Arch of the Diftance BG, intercepted between the two Places is 7 degr. 12 min. but the Diftance itfelf is accounted 5.000 Furlongs (8 of which make an Italian Mile). Therefore by the Golden Rule, as 7 degr. 12 7mn. is to i degr. (or as i'o to 360, or as 36 to 5) fo is 5000 to 694^ Furlongs in i degr. Or as To is to i, (or as i to 50) fo is 5000 to 25000 Furlongs, the whole Periphery, according to this Meafure. There are divers ways of taking the Meridian Altitude of the Sun, or it's Diftance from the Vertex •, as by a Quadrant, (ffc. Eratojlhe- nes found it by a hollow hemifpherical Dial ; where the Style BX {Fig. 7.} points to the Zenith, and OXZ is a Ray of the Sun ter- minating the Shadow of the Style, and fhews the Arch B Z equal to O B 7 degr. 1 2 min. the Diftance of the Sun from the Zenith. But at Syene the Style hath no Shadow -, nor hath the Sun any Di- ftance from the Zenith i being perpendicular to the Plane of the Place. Therefore fince BXZ (Fig. 6, 7.) is equal to the Angle /'X O, (whofe Meafure is B G or Z'O) B G is equal to B Z 7 degr. 12 min. or ro Part of the Periphery, as before. The third Method, that o/Poftdonius. POSIDONIUS took two Places under the fame Meridian ; viz. B, Rhodes, the Place where he lived, and G, Alexandria in Egypt j and ob- ferved the Altitude of the Star S {Fig. 6.) fa bright Star in the Ship Argo called Canopui) when it came to the Meridian of both Places, on the fame, or C H A p. 4- tf 'U?2iverfal Geography. ^^y cr which is all one, on different Days. This Star did not rife above the Horizon h H s at Rhodes, but only glanced upon it at S : tho' it was elevated above the Horizon ot Alexandria FR T, the Arch is :j7Part of the Periphery or 7 degr. 30 min. He tells us the Diftance betwixt Alexandria and Rhodes is 5.000 Furlongs. Therefore, as 7 degr. 30 min. is to I degr. (or as -^ to -^-^^ i. e. as 360 to 48) fo is 5.000 to 6667 Furlongs in i degr. or as i : 48 : : 5,000 : 24,000 Furlongs, for the whole Periphe- ry of the Earth, according to Rofidonius. '^he fourth M-clhod^ that of Snellius. IN the Methods above delivered, we have con- ftantly fuppofed the two Places to lie under the fame Meridian ; but becaufe Places may lie plain- er, and more commodious for this Purpofe under different Meridians, we fnall propofe an Example in this Cafe which is that of Snellius. LET therefore ABCD {Fig. 6.) be the Me- ridian of Alcmair, and B, Alcmalr itfelf ; where the Elevation of the Pole ^ <^ is 52 degr. 40^ min. and the Polar Diftance B A 37 degr. ic)i min. 30 fee. LET the other Place P be Bergen- op-zfxnn, whofe Meridian is A PC, and it's Diftance from the Pole, or Complement of Latitude {viz. to 51 degr. 29 i?iin.) is A P 38 degr. 31 7nin. there- fore, having drawn P G perpendicular to A BG, the Difference of their Diftances from the Pole is BG I degr. II min. '^o fee. AFTER Snellius had taken thefe Obfervations, he accurately meafured the Diftance B P, between Alcmair and Bergen., and found it to be ^^yio Rhinland Perches ; and the Angle of Pofition PEG 1 1 degr. 26 7nin. 1 fee. therefore in the right- angled Triangle PEG, the Hypotenufe P B and VOL.

But the Arch B G, as was (aid before, is 715 min. therefore as 71^ is to i dcgr. or 60 7nin. ibis 33930 (or 34018) 1028473 Perches; or the round Number 28500 for i dfgr. equal to 19 Dutch Miles. Or by fpherical Trigonometry •, having A B, A P, and the Angle A B P given, find the Arch BP I d::gr. 14. fnhi. which equals 34710 Perches ; therefore i degr. will be 28300 Perches, or 1 87 Miles. The Reafon why this Account differs from that oi' Sueiiius h -, i. He did not obferve the Elevation of the Pole from the very Tops of the Towers B and P themfelves, from whence the An- gle GBP was taken, but from fome Eminence or rifing Ground a little remote from them : yet with- out Doubt the Altitudes of the Pole were the iame on the Tops of the Towers. 2. Another Reafon is, he took BG, BP, PG for right Lines, which are indeed circular -, tho*, in fo fmall an Arch, the Difference is of little or no Moment. There- fore, granting 5;7(?//f;/i's Meafure of a Degree to be 28500 Perches, equal to 18^^ Miles, (and mine 28 3 00 making i8tj the Perimeter of the Earth will be, according to Snellius^ 10.260.000 Per- ches, or 123.120.000 Feet, that is 6.840 Holland Miles {a). {a) The Meafure of the ficukies, the curious have not Earth which Snellius with great thought it fafe to confide in a- Ir.duftry difcovered, hath been ny one, tho' the moft fkillful, defervedly embraced by the Mathematician ; which we fee Learned ; as being much more confiimed by CaJJini, the Son accurate than any of the for- of the famous Allronomer of mer.

Wherefore we e- fteem it well worth the while, to give the whole Method of Operation in fhort. The Points in the Figure which are marked with Roman Letters, Ihew the Places cho- fen for Observation ; whofe Bearing, or Situation, in refpeft of the Royal Obferv^atory at Paris, is feen in a Geographical Map. [See Fig. 8.) By the fame Method of Men- furation which Smllius ufed. they propofed to find the Di- ftance between the Parallels of the Places N and E, or the Line N ct in Fathoms ; fo that this Diftance being known, and the Latitude of each Place N and E, or the Difference of Latitude ; that is an Arch of the Meridian intercepted be- tween the two Parallels, being found, it will appear how ma- ny Fathoms make any deter- mined Arch of a great Circle of the Earth, fuch as the Me- ridian is : from whence it will be eafily found how many Fa- thoms equal a Degree, or the v/hole Periphery of the Earth. Afterwards it was thought fit to meafure the Line N p, the Diftance between the Parallels of the Places N and Q__; fo that the Latitude at Q__ being alfo obferved, there might be had an Arch of the Meridian equal to the whole Diftance {i ct. For by this Iv leans, they could more accurately de- termine the Meafure of the Earth's Periphery, when they had found it the fame by two Operations. Thefe Lines they meafured by a continued Series of Triangles drawn from the Line A B ; for it being direftly plane and ftraight, they had the Advan- tage of meafuring it with Lon Rods as accurately as could E z be. 52 be, and found it to be 5663 Fathom?.

Hence i Degree is 57.057 Fa- thoms. Therefore there was taken for I degr. 57.060 Fath. an in- termediate Number betwixt thefe two. Thus with great Labour they acquired the Meafure of i Degr. of the Periphery of the Earth as accurately as poffible. Ne- verthelefs it is to be confeffed, the Difficulty of making Obfer- vations (efpecially tliofe about the Latitude of the Place) was fo great, that it really baffled the profound Endeavours of the diligent Obfervers. And tho' the Inllrument was exquifitely divided, and of 10 Foot Radi- us, yet they could not avoid an Error of 2 Seconds, v/hich on the Earth make 22 Fathoms; by which the obferved Lati- tude of each Place might be wrong. Since this Error could not be avoided, it was thought neceffary to meafure a greater Space, fo that it might be di- vided among more Degrees, by which means a leffer Por- tion of it would faU to any one. This the famous CaJJlm eHe- (f;ed a few Years ago, at the Command of the moft Chriiiiaa King, as he was marking a Meridian for the Obfervatcry at Paris, thro' tliC South Pro- vinces of France. He then meafiired with the fiime Care all tliat Space between Faris and the Pyre/iean Mountains ; to which if the former Diftance betv/een Mal'vofine and A?nkns be added, they make 7 \ Degr. Hence the Meafure of the Earth is procured more accu- rately, and concluded on more fafely, than from the former Obfervations only. And by this Menfaration he found i Degr. to make 57.292 Fath. v/hicli by the former v/as computed to be 57.060 Fath.

Of the Motion of the Earth. ^Jf^ H E Pythagorean Motion or Circumvolution X of the Earth fnot a Nutation or Quaking) is according to the Coper nicain the Caufe of molt of the Changes in the Celeftial Appearances, v/hich would otherwife be conftantly the fame in every Place {a), Tho' indeed there is not any Property ,0 of [a) This Syftem was not in- vented by Pythagoras, as fome imagine, for Diogenes Ldertius exprefsly faith, that Pythago- ras'i Opinion was, That the World n>jas round, co-ntaining the Earth in the ?niddle of it \ and that Phihlaus, the Pythago- rean, was the firft that faid the I^larth moved in a Circle : But fome fay tlercetas the Syracu- Jian. Derhams Ajlro-Theology. Pythagoras, who lived in So- ciety with the Egyptian PiieJIs feven Years, and was initiated into their Religion, carried home from thence, befides fe- veral Geometrical Inventions, the true Syllem of the Uni- verfe, and was the firft that taught in Greece, that the Earth and Planets turned round the vSun, which was immovea- ble in the Center ; and that the Diurnal Motion of the Sun and fixed Stars, was not real but ap- parent, arifing from the Mo- tion of the Earth round it's Axis. The next Perfon who made a confiderable Figure this way, was Ptolemy with his Cycles, Epicycles, and Eccentrics, he quite burthened Nature, and his Hypothefis Ihews too much of Art j thefe are all now explo- ded, and his folid Spheres broke to pieces ; he left behind him a Work entitled Almagcjl, or the great Conftradtion, which was founded on the Oblervations of Hipparchus. Copernicus had the Honour to reftore the ancient Pytha- gorean Syftem, notwithftanding the PrepofTelTion the Ptolemaic had gained in the World. To thefe fucceedcd the No- ble Dane, T^ycho Brake, whofe Hypothefis in a great Meafure is compounded of the other two, and feems defigned to account for Chap. 5' of Vnherfal Geography. 65 of the Earth fo much difputed againft and cavil- led at as this -, fo as even not long ago to have undergone the Cenfure of the liomi/Jj Church. However, becaufe it feems very probable to many that there is fuch a Motion, we Ihall endeavour to explain it. I T is known to all, even the Vulgar, that the Sun, Moon, and Stars, appear to move from Eafb to Weft, and to return to almoft the fame Places again in the Heavens, in the Space of twenty four Hours. So that either they muft really move, or we our felves be moved •, and attribute our Motion to them. For it is a felf-evident Prin- ciple, that if two Things change their Diftance from one another, one of them, at leaft, mufl have moved. THAT the Earth is fixed, or at Reft, and the Stars with the Heavens in Motion, was a common Opinion ; and is fo ftill among thofe that are ac- counted Ptolemaic Aftronomers : But the Pythago- reans of old maintained, that the Stars conftantly kept their Places ; and that the Earth was revol- ved about it*s Center. Of which Sedl was the ctl^ihmizd Anjlarchus o^ Samos \ who, for defend- ing this Opinion, was, by his Enemy and Adver- fary, accufed, before the Bench of the Areopagites^ of having violated the Lav/s of Religion ; but v/as fortunately abfolved by them*. Afterwards, buc very for the difficulties of both of the Celeftial Bodies obfcrve in them, and fo is liable to leveral their i\Iotion, and laid the Objeftions in them both. He Ground-work of the Modern was very fkillful in obferving, Philofophy. Thus I have given and in the Furniture of his a fhort Skctcli of the Rife and Obfervatory exceeded even Perfedlion of this Science.

L F H« 66 "The Ahjolute Fart S e ct. II. very few ailented to this Opinion ; fo that it lay hid, or, as ic were, buried in Oblivion for many- Ages ; infomuch that we find not the leaft men- tion of it in tiie Schools, till the famous Afhrono- mer Copernicus^ about 200 Years ago, brought it again into Eftimation, and backed it with feveral Arguments, fo that many excellent Aftronomers af- ter him embraced it •, among whom flourifhed not long fince the great Kepler, Profeffor of Mathema- tics to the Emperor ; and Galiltxo an Italian, Ma- thematician to the great Duke of Tufcany ; as alfo Lanjberg a Dutchman. AND whereas we obferve two apparent Mo- tions in the Pleavenly Bodies (one by which all the Stars both fixed and wandering feem be car- ried about the Earth, and to rife to the Meridian, and fet under the Horizon nearl-y in the fame or equal Times : The other, which is called their Annual Motion ; by which the Planets with dif- ferent Motions, and the fixed Stars with equal Ve- locity, are carried the contrary Way from Weft to Eaft) the Ptclemaics affirm both thefe Motions to be in the Stars themfelves, or in their Orbs ; But the Copernicans attribute this firft apparent Mo- tion to that real one of the Earth, not in being transferred from one Place to another, but to it's Rotation about it's Axis from Weft to Eaft, while it continues ftill in it's own Place fwhich caufeth the apparent Motion of all the Stars the contrary way). And they alfo free the Sun and the fixed Stars from the aforefaid annual Motion, by attri- He was brought before the proper Center. The poor Man Inqulfition, and obliged folemn- was forced to fay, that he did, ly to abjure his Aftronomical with a fincere Heart, and Faith Tenets, that the Sun frood im- unfeigned, abjure, curfe, and movable in the midft of the deteil, the aforefaid Errors and Univerfe, and that the Earth Herefies. moved round it, as about it's buting J H A p. 5. of Vitlverfal Geography, 67 juting the apparent Motion of thefe to the real an- nual Motion of the Earth round the Sun ; and to the liiclinarion ot it's Axis : Notwidiftanding they affign this fliid annual Motion to the reft of the Planets -, only they deny the Sun to be a Planet, and advance him to the Center of the S\ftemy where Ptolemy had placed the Earth •, and make the reft of the Planets, Saturn, Jupiter, Mars^ the Earth, Venus, and Mercury, revolve round him. THE Reafons for the Copernican Ihpothefis are thefe. 1. T H E Motion of the Earth round it's Axis, continuing in the flime Place, will beft account for the Appearance of fuch a vaft Number of Stars, which feem to perform their Revolutions round the Earth in 24 Hours ; and therefore this Mo- tion is moft agreeable to Reafon : As it happens with us when we fit in a Ship, failing towards o- thers at Reft in the Harbour ; tho' they feem to approach and come nearer us, yet v/e do not affigii that to any Motion in them. And as Nature ne- ver performs that by many means which may be done by a few ; it is very likely the fame Rule is obferved here. 2. THE Motion of the Stars would thus be incredibly fwift and beyond all Imagination ; be- caufe their Diftance, in Refped of us, is almoft infi- nite, and the Orbit they have to run round {o prodigioufty great, that they muft move at leaft 100,000 Miles in a Minute: On the other hand, if this Motion be affigned to the Earth, we nesd not introduce a progrejjive Celerity -, for tho' flie re- mains ftill in the fame part of Space, flie folves the Phsenomena by revolving about her Axis, 3. THIS Argument is the ftronger if we com- pare the vaft Bulk of the Celeftial Bodies with the Bulk ot the Earth. For as the Sun is at leaft 200 F 2 times 6B 1'he Abjolute Tart S e c T. IL times bigger than the Earth, and fome of the fixed Stars 1000 times; it is much more probable, that the Earth revolves round it's Axis with an eafy natural Motion, than that fuch vaft Bodies fliould move from one Place to another with incredible Swiftnefs. 4. THE mod celebrated Aflronomers are, with 1')cho^ forced, by the Phenomena, to deny that there are folid Orbs, fuch as the Ancients made ufe of, the better to explain their imaginary Motion of the Stars; hence their Arguments for this diurnal Rotation about the Earth, are lefs co- gent. The Reafon why they are forced to deny this, is, becaufe that one Planet is often feen with- in the Orb of another ; which muft caufe a mutual Penetration. 5. NO Reafon can be given why the Stars ihould move round the Earth : But on the other hand, it is moil agreeable to Reafon, that the Earth, and the reft of the Planets, fhould move about the Sun. 6. NEITHER the Pole nor the Axh about which the Stars are fuppofed to revolve, is real : On the contrary, there is a known Pole and Aviii in the Earth. 7. F O R this Reafon alfo Navigation is much ealier from. Weft to Eaft than the contrary Way. For they can fail from Europe to India in about four Months ; but can fcarce return in lix Months : becaufe in their going they move to the fame Point with the Earth ; but in their returning they fteer contrary to the Earth's Motion. 8. BECAUSE the Celejlial Phcenomena, fuch as the rifing and fetting of the Stars, the Inequali- ty of Days, i^c. cannot be accounted for, by any other Motion than that of the Earth. And the Commodioufnefs and NecefTity of this Hypothefis, is more particularly perceived in the wonderful Ap- I pearances C H A p. 5- of Vniverfal Geography. 6g psarances of the Planets •, for explaining of which the Plolemaics are forced to fuppofe feveral unnecef- fary interfering Circles, Epicycles, arA Eccentrics, without any Reafon : Whereas the Copermcans can naturally account for them all, (without any pre- vious Suppofitions,) by the annual Motion of the Earth, or it's Revolution round the Sun, viz. I. Why the Planets feem fometimes retrograde; and why Saturn is oftener and continues longer fo than Jupiter ; and Jupiter oftener and longer fo than Mars, &c. and alio why they are carried fometimes with a fwifter Motion, and at other times appear flationary. 2. Why Mercury and Venus can never be feen a v/hole Night together. 3. Why Venus is never carried further from the Sun than 48 degr. and Mercury never more than 28 ; and fo can never be feen in Oppofition to the Sun. 4.

Gajfendus, by repeated Experiments, found, that if a Body be proje6ced from another Body in Motion, it will partake of the Motion of that other Body ; as a Stone dropped from the Top of a Maft, while the Ship is in a very fwift Motion, is not left by the Ship but fills at the Foot of the Maft. Alio a Ball fhot perpendicu- larly from the Foot of the Maft tails in the very fame Place. Therefore the Objedion is of no Force. T O xht fourth they anfwer as to the third. TW'E fifth Objedion hath no Place, becaufc the Motion of the Earth is even and uniform, with- out dafhing or ftriking againft any other Body ; and the Buildings being heavy Bodies, and homo- geneous to the Earth, are moved as if they were in a Ship -, which tho' it ^ils either fwiftly or flow- ly, yet if the Motion be even and fteady without Waves and on fmooth Water, Bodies fet upright will not be overturned, nor a Glafs of Wine be fpilt. T O the fixth v/e anfwer, that we are nor fen- fible of any Change of Place in the Stars, only of their Situation in Refpe6t of our felves; which may appear and really be, whether we with the Earth, or the Stars themfelves are moved; or even tho' both we and the Stars ftiould be in Mo- tion {b).

Tiien fuppoic the Body to fall from the top of the Maft B, to the foot D, in the fame Time the Ship moves from D to G ; and it is phiin, that, by the mutual afting of B D, the centripetal Force, and BF = DG, the Ship's Motion, the Body will fall in t'ne diagonal Line BG, and alfo accompany the Maft in it's Motion from D to G ; fo that tho' it was really carri- ed in t!ie Lines MB, BG, yet it will feem to have moved, on- ly upwards and downwards, pa- rallel to the Line F G. Alfo (in Fig. lo.) let MT be the fame Maft, and fuppofe a Projeftile to be caft eaft- ward from the Stern S, to the top of the Maft T, in the Time the Ship moves alfo eaftward from M to D; then will it's Motion upwards defcribe the Diagonal S B ; where let it be obftrufted fo as to feem to fall perpendicularly to D, in the ftrime the Ship moves from D to G ; then, as before, it will defcribe the Diagonal BG, tho' it fcemed to move upwards only in the LineTS, and dov/nwards inFG. So (in Fig. II.) if a Body be projefted weftward from the Head of the Ship H to the top of the Maft T, in the time it moves eaftward, HG equal to the Diftance M H, then will it's Motion upwaids defcribe the perpendicular Line HB, And if in the fame time it feems to defcend from B to H that the Maft moves H G ^ G /^ c= M H, it's Motion down- wards v/ill defcribe the Diago- nal BG. So that, in this Cafe, it afcends by a perpendicular Line, and falls by an inclining Line ; tho' it feemed to afcend by the inclined Line h F, and to fall by the perpendicular LineF G. Hence it is plain that bodies may appear to have a A-Iotion, diredly contrary to their real and abfolute Motion : fo that it is pleafant to conceive, how falily we may judge of the Motion of Bodies by their une- qual Diftance from us ; not con- fidering that we may be infen- fibly moved from them. Hence alfo is deduced that ingenious Experiment of Gali- Irco, mentioned in Derharns JJiro-Theology, as follows. ' Shut yourfelf up [fays he) * with your Friend in the great * Cabin of a Ship, together * with a Parcel of Gnats and ' p'lies, and other little winged ' Creatures.

And if you throw any thing to your Friend you need ufe no more Force one way than another ; provided the Di- ftances be equal. And if you leap, you will reach as far one way as the other. Hav- ing obferved thefe Particulars whilft the Ship lies ftill, make the Ship to fail with what Velocity you pleafe ; and fo long as the motion is uni- form, not fluftuating this Way and that Way, you fhall not perceive there is any Al- teration in the aforefaid Ef- fe6ls ; neither can you from them conclude whether the Ship movcth or ftandeth Hill. But in leaping you fhall reach as far on the Floor as you did before ; nor by any Reafon of the Ship's Motion fhall you make a longer leap towards the Poop than the Prow ; notwithftanding that whilft you are up in the Air, the Floor under your Feet had run the contrary Way to your Leap. And if you cafe any thing to your Compa- nion, you need ufe no more Strength to make it reach him, if he fhould be towards the Prow and you towards * the Poop, than if you flood ' in a contrary Polition. I'he ' Drops fhall all fall into the * Bottle that is lower ; and not ' one towards the Poop, al- ' tho' the Ship fhall have run ' many Feet, whilft the Drop ' was in the Air.

TH E R E are feveral Opinions of Philofophers concerning this matter. The Peripatetics reckon four Elements in the Earth and the whole Sublu- nary World, fufficiently known to every one, viz. Fire, Jir, tVater, and Earth. Many of the An- tients, as Dnnocritus, Leucippus, ^c. were of Opi- nion, that tne whole World confided of very fmali Iblid Particles, which only differed in Mag- nitude ana Shape. Which Opinion is followed by feveral of the Moderns ; and fome time fince, des Cartes endeavoured to account for all the Phoe- nomena of Nature upon this Hypothefis. THE Chymifts imagine that there are three Pmcz/)/^i of Nature, viz. SaJj., Sulphur^ sind Mer- cury, to which Ibme reafonably add Caput Mortu- urn. But there feems to me upon a thorough Confideration of the Matter (to drop all ambiguous terms and quibbles), to be five fiftiple Bodies which are the firft Elements or Principles of all things, viz. Water^ Oil or Sulphur, Salt, Earth, and a fixed Spirit ; which fome call an Acid, and is per- haps like the Mercury of the Chymifts {a).

Nevcrthelefs I do not fuppofe them to differ fo much in their particular Effences, as in the Variety of their feveral Shapes and Magni- tudes. OF thefe Bodies, mixed after different manners, is the whole Earth compofed -, from which pro- ceeds fuch a furprifmg Variety in the Nature of Bodies \ tho' they are apparently fimilar (h). But fmce the more accurate Explication of thefe things belongs to Phyfics, we fliall fay no more to them here ; but handle them at large in another Place. PROPOSITION II. The Earth is divided into dry and moift Parts, or in- to Land and Water ; to which fome add the At- tnofphere. THIS is the common Divifion of Geography. But then Water is taken, in a large Senfe, for all forts of Liquids and Fluids ; and Land for the ■whole dry and confiltent Parts of the Globe : whilfl: to divide what God himfelf made one in the firll Crea- tion. While the Particles continue entire, they may compofe Bodies of one and the fame Nature and Texture in all Ages : But fhould they wear away, or break in pie- ces, the Nature of Things depending on them would be changed. Water and Earth compofed of old worn Parti- cles, and Fragments of Parti- cles, would not be of the fame Nature and Texture now, .with Wat,er an4 Eerth cqm- pofe4 of entire Particles in ' the Beginning.

So that the Earth is belt divided into thefe three Parts. PROPOSITION IIL To explain how the Earth and Water cleave one to a- nother -, and conjlitute the Terraqueous Globe. THE Earth, that is the dry Part of the Globe, is not terminated by an even and fmooth Surface ; but is here and there hollowed into Cavities, and in other Places elevated into Protuberances. In the Cavities found all over the Earth is contained the Ocean or Sea ; fo that this Part of the fuperficies of the Earth is covered with Water, and the other Part is railed and appeareth above the Waters. Thefe Cavities are not deprefied into an equal hol- lownefs, but are in fome Places rugged and rocky ; and in others funk down into Gulphs and Whirl- Pools. Alfo thofe Places of the Earth which are raifcd above the Waters, have in the middle of them, as it were, certain Navels or Eminences ; and fome Parts are either raifed or deprefied more than others. Hence the Water furrounding the whole Chap. 7. of Lhtiverfal Geography. 91 whole Globe is hindred from covering the higher Parts which appear above the Surface ot the Ocean ; and are called IJlands : Whereof Ibme are great and others are fmall. BESIDES that continued Cavity or Channel in the Surfice of the Earth, there are alfb within it's Bowels innumerable Openings, Receffes, Fifilires, Chafms, Mazes, Swallows, Water Paflages, and vaft Receptacles *, fome ot which are filled with fait Water, viz. fuch as are joined by fubterra- neous Paflages to the Main Ocean •, others with frefh Water, Rivers and Brooks •, in fome alfo are fulphureous Vapours, and fmoaking Subftan- ces. So that Seneca feems to be in the right when he fays, 'That he trujls too much to his Sights who does not believe there is a large ^mntity of Sea in the hidden Recejfes of the Earth. Nor do I perceive why there fnould not be much Sea Water receiv- ed by thefe fubterraneous Swallows -, and formed into Bays by Banks or Bounds. And from the fol- lowing Oblervations we cannot doubt, that there are a great many Cavities in the Bowels of the Earth. For feveral fubterraneous Rivers are found in Places where the Earth is dug to a confiderable Depth ; as is common in Mines. 2. The Depth of the Sea is in fome Places unfathomable. 3. There are in feveral Places, Caverns difcovered near the Sur- face of the Earth. Thus in the Weft part of the Ifland of Hifpanioh-» there is a Mountain of a vaft Height all hollowed within, into feveral Dens and Openings, in which Rivers rufti precipitantly with fuch a violent Torrent and Noife of Waters, that they may be heard at five Miles diftance. 4. Se- veral Whirl- Pools are found in the Sea, and called in the Dutch Language Maelftroom. 5. Earth- quakes alfo fhew that there are fuch fubterraneous Caverns. 6. Several Rivers hide themfelves under the Earth, 2,% ih^ Niger, Tigris^ C^c. 7. Brackifh Fountains 92 ^he Ahfolute Tart Sect. II. Fountains are obferved in fevcral Places, moft of which certainly flow from the Sea. 8. In many Places the Ground trembles wiien People walk up- on it, as at the Abby of S. Omer in Flanders ; and in the Province ol Brabant upon Peel Marijh. COROLLARY. Hence it is evident, that the Opinion of thofe old Philofophers, who maintained that the Earth at flrft floated upon the Waters, is falfe ; for by this Means there would be no Channels in the Sea, but it would be every where of an immenfe Depth. Some indeed of the Antients Cefpecially Democritus) are faid to have been of the following Opinion, ^72;. the Waters were formerly mixed with the Earth ; and that the whole Mafs being perfc6lly fpherical, was foftandofan indifferent Conflftence betwixt wet and dry : But afterwards when the Particles of Water were gathered into one Body, according to the natural Property obferved in AVater, the earthly Particles, being feparated from the watery, came together and were curdled into Earth and wrought into Chanels by the Water in fcveral Places. The fime Hypothefis is embra- ced by many modern Chriflian Philofophers, who think thefe Words of Mofes (or rather of G D delivered to us by Mofes) Let the Waters he gather- ed together into one Place ^ and let the dry Land appear, ought to be thus undcrfl:ood. But the Fathers of the Primitive Church thought otherwife about this ; for they judged that the Waters were feparated from the earthy Particles [before the Creation'] and covered the Face of the whole Earth ; and fo oc- cupied their natural Place •, and then miraculoufly receded, and uncovered the Earth by the Power of thefe Words of Jehovah-, and that to this day they are hindred and xeftraiDed, by the efpecial l^rovidence Chap. 7* of Utiiverfal Geography. 93 Providence of God, from flowing back and cover- ing the Face of the whole Earth as before ; fo that the prefent Confticution of the Earth and Sea is by them accounted a perted: Miracle. Buc that there is no great Occafion to think it fo much a Miracle we ihall prove in Chap, xiii, where we fhall fliew, that the Inundation ol the Waters, or Ocean, up- on the adjacent Land, is hindred by the Altitude and Confiltence of the Earth, which if removed by fome certain Caufcs, whereof there are many, the Ocean will foon overflow the dry Land and cover it: whence there is manifefl:ly, no need of a Mi- racle in the matter. Neither does the beforemen- tioned Opinion of the Antients want it's Defe6ts ; for if the Earth and Water had been once mixed into one Mafs -, why did not the earthly Particles rather fubfide, and the Waters, being of lefs Gra- vity, cover the whole Earth? This they are for- ced to afcribe to a fortuitous Motion and Conjun- (flion of the watery and earthy Particles. Thefe things are faid, by the way, to gratify fome that earneilly enquire into fuch matters ; tho' they do not fo properly belong to Geography •, which hath no Regard to the Opinions of the Antients, nor need fly to Miracles in explaining the Properties of the Earth (c) . PROPOSITION IV. The Superficies of the Earth is continued, hut not that of the JVaters. THE Superficies of that Part of the Earth which is raifed above the Waters, is continued to the Superficies of the Chanel of the Sea, and that again to other elevated Parts of the Earth.

MANY Things occur worthy of particular Notice, in explaining the Natue of Moun- tains, and therefore they are copioufly handled by Geographical Writers, efpecially the Computation of their Altitudes^ becaufe they feem to many to make againft the Earth's Rotundity. PROPOSITION I. A Mountain is an elevated Part of the day Land, over- topping the adjacent Country ; and a Hill or ClifF is a /mall kind of Mountain. A Promontory, is a Mountain Jlretching itfelf into the Sea,, and Rocks are Stones raifed above the Sea or Land, in the Form of Mou?itainJ. W E muft know that all the Parts of the Earth which appear plain, are not exadtly of the fame Altitude, but commonly elevated towards the In- land Parts, and depreffed towards the Sea Shores, as is manifeft from the Origin and Courfe of Ri- vers ; for that Part towards which they flow, is al- ways more depreffed than that where they fpring ; and Fountains feldom are increafed into Rivers, unlefs they take their Origin from Mediterranean or inland Countries: which fhews, thatthofe Coun- tries are more elevated than the Maritime Parts. Sq Bohemia is known to be higher than Holfiein, be- I 4 cau.re 120 ^he Abfoliite Tart Sect. Ill, Caufe the River Elbe rifes in the former, and falls into the later. Alfo from the Dtwuhc^ and IVefer, the Rhine, and the Mofelle^ we perceive the greater Altitude of thofe inland Countries, from whence they flow. For this reafon, Switzerland and the Country of the Grifom, are accounted the highefb Lands in Europe \ becaufe the Rhine, the Danube^ and the Rhone, derive their fource from them. Moreover, the inland Countries are elevated above the maritime Parts, according to the different De- (cijyityand Rapidity of the Rivers. HERE follow fome Problems, by which we may form, a Judgment upon the controverfial Wri- tings handed down to us, about the different Alti- tudes of Mountains. PROPOSITION II. to take the Height of a Mountain by Jllimelry. THIS is perform^ed the fame Way as we take the Height of a Tower, provided the very Top of the Mountain be perceptible by any Mark. LET AB (Fi^^. 12.; be the Altitude of a Mountain, A the Foot of it, B the Mark feen at the Top. Take the Line FC at a convenient Diftancc, fo that neidier of the Angles A F C or ACF may be very acute, but nearly equal. Let the Angles BFC and B C F be obferved ; and the Sum of their Degrees being taken from i8o the Remainder will give the Angle CBF (a). Then let C F the Diftance of the two Stations be .accurately meafured -, which done, fiy, as the Sine of the Angle FBC, to the Sine of the Angle PFB: (orofFCB: if you would find F B) fo (rt) Bj Article 14. of Chap. ii. fihv^.

Then ['iviib a Tele/cope fixed to a ^tadrant or othsrwife] take the Angle B C A, and you will have alfo the Angle ABC, becaufe the Triangle C A B is redangular *. THEREFORE in the Triangle A B C, As the Radius 1 0000000, is to the Sine of the Angle B C A : fo is the Diftance B C, to the perpendi- cular Altitude of the Mountain A B. FO R Example, Let us fuppofe that Xenagora^^ the Son of Eumelus, ufed fonie fuch Method as this to find the Height of the Mountain Olympus, which he is faid to have meafured exadly. Where- fore if he found the Angle B F C 84 degr. 18 mv?. and the Angle BCF 85 degr. 34 miu. then was C BF 10 degr. 8 w/«. And fuppofe, by meafuring, or fome other Method, he found F C 1 200 Grecian Feet, or 2 Furlongs. Therefore as the Sine of the Angle CBF 10 degr. 8 min. 17594 is to the Sine of the Angle B C F 85 dtgr. 34 mift. 99701 : fo is C F 1 200 Feet to B F 6800 Feet, the Diftance from the Top. Likewife the Angle B F A being found, by fo7ne Jnjtrument then in Ufe to be 6-^ degr, 30 min. by faying, in the Triangle FAB, As Rad. looooo to the Sine of the Angle BFA 89500 : fo is FB 6800 to A B 6096 Feet, the Altitude of Mount Olympus. But 600 Feet make a Grecian Furlong ; therefore dividing 6096 by 600, the Quotient, 10 Furlongs 96 Feet, is the Height of Mount Olympus in Grecian Mea^jre, as Xena- goras found it. Note, Each of thefe Furlongs is aboiit h of a German Mile. /^ RIS TO TL E and feveral others affirm, that this Mountain, Olyinpus^ is fo high, that there is no Rain, nor the leaft Motion of Air upon the yop of it } which he, and the Ancients underftood f Bj Article 14 of Chap. ii. al>Q-'je, from 122 The Abfolute Part Sect.

THERE is alfo another Method of taking the Altitude of Mountains, by two Stations in the fame Plane, with the perpendicular Height of the Mountain -, but this is fubjeft to Error becaufe of the fmall Difference of the Angles {b). ALSO {b) There i$ a very pleafant and expeditious A'lethod of tak- ing the Height of Mountains by thz Barometer, thus : It is to be obferved how many Inches or Parts of Inches the Quick- filver is depreffed at the Top of the Mountain, we have a mind to meafure, below the Altitude it hath acquired, at the fame Time, at the Bottom or Su- perficies of the Sea ; from whence the true Height of the Mountain is found by an efta- bhfhed Proportion. This Pro- portion may be known by the T^ble we have added below to Chap. xlx. Prop. 7. Alfo, by this Table, the Height of the Quickfilver at the Surface of the Sea may be found, by obferving it's Height at any Place, whofe Altitude above theSca is known. But this is to be obferved, that the Altitudes found this way will be more accurate, the near- er the Height of the Quickfilver is to 28 French Ir,ches or to Jurin*s Appendix. This Way of taking the Hsigbl of Mjun/aim, is verjr expeditious and pleafant, as Dr "Jurin faith, and with due care may be very ufeful to fe- veral purpofes ; particularly in meafuring the Height of IJlands above the Sea, by two Obfer- vers, with well adjufted Baro- meters ; and at the fame Inflant of time, obferving the Baro- metrical Heights, by the Sea- fide, and on the higheft Part of the Jfland. So alfo it may ferve to give an Eftimate of the Height of a fountain, or Ri- ver, that we would have con- veyed to fome Miles Diftance. But in all thofe Experiments, it is necefTary thst the Barometer (as I faid) fhould be well adjull- ed, and (if two Obfervers) that the Obfervations fhould be made at the fame time, to pre- vent errors that may arife from errors in the Barometer, or from the Alteration of th« Weight of the Jtmofpberei which fometimes changes in the very time of Qbfervation, if we are not fpeedy therein.

PROPOSITION IV. Having the Dijiance between a Mountain and the Place where it's Top may be firjl feen, given : to find Geographically the Height of the Mountain. LET us take, for Example, the prodigious high Mountain in the Ifland of Tenerijf, one of the Canaries^ commonly called the Pike of Teneriff. Let AFC, {Fig. 14.) whofe Center is R, be the Periphery of the Earth, or the Meridian of the Mountain, and let A B be the Mountain ilfelf. Draw from B the right Line B F a Tangent to the Periphery, and F will be the firft or laft Point from which the Top of the Mountain can be feen. CThen Draw R ¥) Mariners affirm, that they firft difcover the Top of this Mountain when they are 4 Degr. of the Meridian diftant from it (and they need not be at a lofs for finding the Diftance from any Mountain in Degrees when they are failing under the fame Meridian it is in). Therefore, fup- pofing their Relation to be true, and the firft villial Ray B F to come in a diredl Line from the Top B, let us endeavour to find out the Alti- tv,dQ Chap. 9« of Univerjal Geography. 12^ tude of the Mountain. In the Triangle B R F there are three Things known, i. R F the Sennidiame- ter of the Earth. 2. The Right-angle B F R. Ani 3. Becaufe the Arch FA is 4 Degr. the Angle B R F is alfo 4. Degr. Therefore fay, As the Ra- dius (looooooooj is to the Secant of the Angle BRF 4 Degr.

Therefore we mull know that there are two Things affumed as Truths which are actually falfe. i . It is fuppofed that the Ray of Light which firfc ftrikes the Eye, comer from B in a right Line, when it is knov/n on the contrary to be curved, or refra6led, by Reafon of the Denfity of the Atmofphere. For a Right Line cannot be drawn trom the Top B to F (F A being 4 Degr.j without paffing thro' a Part of the Earth, and therefore the Top B cannot be feen in a right Line from the Place F, but by the bowed Ray B T F, being the firft of the re- fra6i:ed Rays that can touch F. From whence we way reafonably infer, that this Refra<5lion caufes the Mountain to be difcovered fooner by i Degr. (or 15 German Miles) than if there had been no Re- fradion at all ; fo that fuppofing A F but 3 Degr. the Height of the Mountain will be found but 40 Furlongs, or 5 Italian Miles. 2. It is to be con- fidered, that Sailors allow themfelvcs a Liberty of fpeaking largely, efpecially about their Diilances ; if therefore, in Confideration of this, we dedudt half a Degr. more, and fuppofe the Top firft ittn at 21 Degr. or 38 German Miles equal to jF A -, then will the Altitude of the Mountain A B be 2 found 126 Th^ Ahjoiiite Fart Sect.

But the Refraftion varies according to the different Altitude of the Sun, or the different Denfity of the Air, when the Sun, is below the Horizon -, as we fhall fhew more at large, when we come to treat of the Atmofphere % and in the third Part of this Book, where we (hall difcourfe of the vifible Horizon, PROPOSITION VL ^he Length of the Shadow of a Mountain^ and the: Altitude of the Sun at the fame "time, being given g to find the Altitude of the Mountain. W E propofe this Problem more for the Anti- quity and Elegancy of it, than for any Accuracy we believe to be in the Method. Plutarch and Pliny have writ, that Mount Athos, on the Mace- donian Shore, is fo high, as that it overfliadoweth the IQe of Lemnos, [}tow called Stalimene] as far as the Market-place of the City of Myrrhina [or Lemnos]^ when the Sun is in the Summer Solftice ; where the ancient Inhabitants for the Curiofity of the Appear- ance erected a Brazen Calf, at the termination of the Shadow, as is teftified by the old Greek Mo= noflich, which may be thus EngliJJjed.

We may fup- pofe the Sun to have been almoft in the very Ho- rizon of Myrrhina F O, and fo the Ray O F, paf- fing the Top of the Mountain, to have projedied the Shadow AF {Fig. 15). Here O F is a Tan- gent to the Periphery, and from having the Angle FB R given, and alio F R, (or FA in the Trian- gle, BAF taken as a right lAne) BA will be iound to be 8 Furlongs, or i Italian Mile for the Height of a Mountain. But becaufe in this Por- tion of the Sun, the Shadow would be infinitely continued, and therefore it's Extent could not be' obferved ; and as the Interpofition of the Houfes- in the Town, would alio intercept the neighbour- ing Rays, to thofe that bounded the Shadow •, there- fore, we muft allow the Sun to have been elevated at leaft 2 Degr. above the Horizon of Myrrhina ; (^) 'A^votf Kcthv^-ei 'TsKiv^a. f.uv the Shadow of the Pike of Kr^iy.v'iA?

IF we afllime the Altitude of the Sun to be but one Degr. the Altitude of the Mountain will be found but 20 Furlongs. BUT PUn'j^ I fuppofe, has given us too large a Diftance betwixt Athos and Myrhina., which may perhaps be a Reafon, that too great a Height arifes froni this Calculation : and in moft of our modern Maps of Greece, the Diftance FA feems to be but about ss Italian Miles j wherefore the Angle F R T will be but about P)P, min.

Having the dillerence of Time be- tween the Sun's rifing ("or letting) on the Top of a Mountain, and it's hril Appearance to for Occul- ration fromj an Obferver at the Bottom, to find, if required, the Height of the Mountain •, and con- verfly, having the Height of the Mountain, to find this difference of Time. Arijlotle and P/iwj, have, by this Method of Calculation, fuppofed fome Mountains to be of incredible Altitudes, as ap- pears from their Writings. However, fince the Solution of thefe Problems depends upon another, which we have referred to the fecond Part of this "Work, we fhall refer them to Chapter xxx. P RO PO S I'TION VII. The highejl Mountains have no fmfihle Tro portion to the Se?nidiaj?ieter of the Earth ; or fo little, that their Altitude no 7nore affecls ii*s Rotundity, than a fpeck or particle of Dufl upon the Surface of the artificial Globe does it's Rotundity.

But few Moun- tains are of this Height, moft of them not exceed- ing a quarter of a Mile ; wherefore they no more obftruft the Earth's fpherical Figure, than the fmall inequality obferved in Globes turned artifi- cially, does their Rotundity 5 and Nature hath not 3 yet C H A p. 9- ^f Univerfal Geography. 1 3 1 yet been able to produce a Body of an exad Geo- metrical Roundnefs {d).

Some Mountains are of /mall Extent, and others run out to a great Dijlance, TH E latter Sort, called Ridges, or Chains of Mountains, are found almoft in every Country throughout the World ; and fuch might be account- ed one continued Mountain, if it were not for fmall Breaches or Paflages that fometimes intervene. They are indifferently extended feveral Ways % fome from North to South, others from Eaft to Weft, and fome to other Points collateral to the four Cardinal ones. THE moft celebrated Ridges of Mountains are, I . THE Alps, which feparate Italy from the neighbouring Provinces, extending themfelves over vaft Tratfts of Land, and ftretching out their Arms, or Branches, into diftant Countries, viz, thro* France to Spain, where they are called the Pyreneans ; and thro* Rhcetia, [i. e. the Country of the Grifons'] where they are called the Rhetian Mountains ; alfo thro* Hungary, where they are named the Hungarian Mountains ; and above DaU matia, where they receive the Name of the Dal- matian Mountains , from whence they are ftretch- K4 cd 136 ^he Ahfolute Tart S e c T.

But bccaufe there is in Daimatia a confiderable Space between the Alps and the DalmaUan Mountains, the former is reck- oned by fome to end here. Neverthelefs they fend out one continued Ridge, which paffeth, with a winding Courfe, in the Form of a Half-Moon, thro' the whole Length of 7/^/)', and divides it into two Parts even to the Streights of \MeJjuia\ ; tho' it does not run every where directly for- ward in one Trad, but here and there fends out collateral Branches that run fideways from it. Se- veral ot thefe Mountains are diftinguifhed by par- ticular Names, by Reafon of their Altitude, or for fome other Caufe, as Monte MaJJo, GauruSy Monte di Capua, the burning Mount Vefu- 'viiis. Sec. 2. THE Ridge of Mountains in Peru [called the Andes] is the longeft in the World. They run in a continued Tra<5l about 800 Gennan Miles, (whereof 15 rrjake a Degree j thro* all South Ame- rica, from the Equator to the Streights of Ma- gellan, and feparate the Kingdom of Peru, from other Provinces. And fo high are the Tops of thefe Mountains, that they are reported to tire the Birds in their Flight over them ; there being but one only Paffiige over them as yet difcovered, and that very difficult. Many of them are covered with perpetual Snow, as well in Summer as in Winter. The Tops of others are hid in the Clouds, and fome are raifed above the middle Regionof the Air. StwtvdX ol t\\z Spaniards, with their Horfes, have fuddcnly expired upon the Tops of thefe Mountains, in their Paffage from Nicaragua to Peru, and growing ftifF with the Coki, they, in a Monnent, became immoveable as Statues.

There are alfo found among this Ridge of Mountains feverai that are fulphureoui and fmoaking. 3. T H E R E are many other Ridges of Moun"- tains between Peru and Brafi!^ which are ilretched out thro' unknown Countries as far as the Streights of Magellan^ where their Tops are covered with continual Snow, tho' they lie in the Latitude of 52 Degrees. " 4. T O thefe may be added the Ridges of Moun- tains in Canada^ and Nezv England, whofe Tops are alfo perpetually covered with Snow, tho' they are not fo famous as the reft. 5. MOUN'T Tatirus, in ylfia, was antiently thought to make a Part of the largeft and nobleft- Ridge of Mountains in the World. It begins to fhew itfelf in the hcjfdr Afia near \lhe Gulpb of Statalia], and runs from Weft to Eaft, under fe- verai Names, thro' divers large Kingdoms, and Countries, even to India •, whereby all Jfia is di- vided into two Parts, of which that on the North Side is called Jfia intra Taiirum, and that on the South, Afia extra Taiirum. This Ridge is as it were fenced on either Side with feverai others that, accompany it, among which the moft celebrated arc the Greater and Lejfer Antitaurus, which fepa- rate the Greater Armenia from the hejjer ; alfo where Taurus itfelf paffes between Armenia and Mefopotamia, it fends forth many Branches towards the North and South. 6. T H E Mountain If?iaus is extended North and South, and alfo Eaft and Weft, in the Form of a Crofs. The North Portion of it, is now called Alkai : It is ftretched out fouthward as far as the Borders of India, to the very Head of the River Ganges, and is computed in Length about 400 Gd-r- f.»?^» Miles, It divides [ Aft atic Tartar -j] into two Parts 138 The Abfolute Part Sect.

THE Mountains of Caucafus are about 50 Miles in Breadth, and extend themfelves length- way from the Confines of the Cafpian-Sea towards the Euxine-Sea. They are a fure Sea- Mark to thofe that fail in the Cafpian-Sea^ to fteer their Courfe by. An Arm of them reaches to Mount Ararat in Armenia, upon which it is faid, in Sacred Scrip- ture, the Ark of Noah reded j and the Turks and Perfiam will have it to be preferved there to this very Day.

The Mountains of Cambodia feem al- fo to be a Part of this Range. 9. T H E Mountains of Arabia are drawn out in three Ranks, whereof the holy Mount Sinai is a Part. 10. MOUNT Atlas, m Africa, is made famous by the innumerable Fi6lions of the Greek Poets. It's Rife is near the weftern Shore of Africa, from whence it ftretches itfelf to the eaftward as far as the Confines of Egypt. Moft of the Rivers in this Continent take their Rife from it ; and tho' it lie in the Torrid Zone it is cold and covered with Snow in feveral Places. 11. THE Mountains of the Moon, near Monomo- tapa in Africa, fendeth out feveral Branches, which furround almoft all Monomotapa, and are diftin- guiflied by divers Names, as Zethy [Gil^el, Caph,] Chap, i o. of Untverfal Geography. 130 &c. There are almoft innumerable other Branches in Africa^ feparated one from another only by nar- row Pafiages, infomuch that they all feem to be Parts of the fame Range of Mountains. 12. THE Riphean Mountains, in Europe^ run from the White-Sea^ or Mufcovian-Bay^ to the Mouth of the River Oh'j •, from whence they are called fometimes by that Name. The Mufcovites call them IVeliki Kamefiypoys^ 1. e. ihe great fiony Girdle ; becaufe they fuppofe them to encompals the whole Earth. Near thefe there is another Ridge of Mountains, which the RuJJtans call Joe- goria ; they reach from the South Borders of Tar~ tary to the Northern Ocean, Several Rivers take their Rife from them, viz. Witfagda, Neem^ Wiffera, and Petfiora. Thefe are none of them well re- prefented in Maps, and very often totally omit- ted. Alfo between Ruffia and Siberia there are, befides thefe, a triple Range of Mountains run- ning from North to South. The firft of thefe the Ruffians call Cofvinfcoy Camen^ v/hich is two Days in pafTing over. The next to this (fome Vallies intervening) is called Chirginfcoy Camen, v/hich is alfo two Days Journey over. The third, being higher than the refb, is named Podvinfcoy Camen^ and in feveral Places is all the Year round co- vered with Snow and Fogs, fo that a PafTage is, with great Difficulty, obtained in four Days. The Town of Vergateria, in Siberia, is near this Range. 13.

In inofl IJIandSy and Parts of the Continent that run out into the Sea, the Ridges of Mountains are fo fituated as to take their Courfe thro' the middle of them, and divide them into two Parts. I N Scotland the Grampian Mountain for Granf- lain as the Inhabitants call it) runs from Weft to Eaft tho' the middle of" this Peninfula •, and di- vides it into two Parts, which very much differ both in the Nature of the Soil, and the Inhabi- tants. So in the Iflands of Sumatra, Borneo, Lu- conia, Celebes, Cuba, Tlifpaniola, &c. Chains of Mountains are found which arife gradually to a great Height, from the Sea-Shore to the Inland Parts. THUS the Mountain Gate, in India, begins at the Extremity of Mount Caucafus, and reaches to Cape Comorin -, whereby the Peninfula of India is divided, from North to South, into two Parts, whereof that Part which lies on this Side Gate, towards the Weft, is called Malabar -, and the other beyond the Mountain towards the Eaft is called Cormandel. Part of the fame Ridge of Mountains is alfo ftretched out into that Part of India which is now called Bengal, and from thence thro' Pegu, Siam, to the extream Parts of Malacca. THERE is the like Ridge of Mountains in the Peninfula of Cambaya, and in the Ifland, or Peninfula, of Cahfornia ; alfo in the procurrent Parts of Africa, there is a Ridge v/hich reaches from Chap, i o . of TJniverJal Geography. 141 from the Morafs of Zaire to the Cape of Good-Hope.

Thofe Countries which yield great ftore of Sul- phur and Nitre, or where Sul- phur is fublimed from the Py- rites, are by far the moil inju- red and incommoded by Earth- quakes; for where there are fuch Mines they muft fend up Exha- lations, which meeting with fub- terraneons Caverns, they muft Hick to the Arches of them, as Soot does to the Sides of our Chimnies, where they mix themfelves with the Nitre or Saltpeter, which comes out of thefe Arches, in like manner as we fee it come out of the In- fide of the Arch of a Bridge, and fo makes a kind of Cruft which will very eafily take Fire. There are feveral ways by which this Cruft may take Fire, njiz. I . By the inflammable Breath of the Pyrites, which is a kind of Sulphur thatnaturally takes Fire ofitfelf. 2. By a Fermentation of Vapours to a degree of Heat, equal to that of Fire and Flame. 3 . To the falling of fome great Stone, which is undermined by Water,and ftrikingagainft ano- ther, produces fome Sparks which fet Fire to the combufti- ble Matter that is near ; which being a kind of natural Gun- Powder, at the Appulfe of the Fire, goes off (if I may fo fay) with a fudden Blaft or violent Explofion, rumbling in the Bowels of the Earth, and lift- ing up the Ground above it, fo as fomctimes to make mife- rable Havock and Dellruftion, 'till it gets Vent or a Difcharge. Burning Mountains and Vulca- nos are only fo many Spiracles ferving for the Difcharge of this fubterranean Fire,when it is thus preternaturallyaflembled. And where there happens to be fuch a Strufture and Confor- mation of the interior Parts of the Earth, that the Fire may pafs freely and without Impedi- ment from the Caverns therein, it alTembles unto thefe Spiracles, and then readily and ealily gets out, from Time to Time, with- out fliaking or difturbing the Earth. But where fuch Com- munication is wanting, or the Paflages not fufficiently large and open, fo that it cannot come at the faid Spiracles without firft forcing and removing all Ob- ftacles, it heaves up and fhocks the Earth, till it hath made it's Ways to the Mouth of the Vul- cano; where it ruftieth forth, fometimes in mighty Flames, with great Velocity, and a ter- rible bellowing Noife.

I N Guinea there are feveral Mountains, that produce Gold, but they are remote from the Shore, and the Gold- Dull that is brought from thence, is not dug out of the Ground, but gathered up and down by the Natives. Their in-land Kings are how- ever faid to pofTefs each his Mine, the Produdt of which he fells to the Neighbouring Merchants, and they again to others, till it reaches the Sea-Shore, where it is exchanged with the Europeans, 6.

Here are alfo Iron- Mines, and fome Silver- Mines, but they fcarcely defray the Expence of digging them. 9. THERE are Mines of precious Stones found in the IQand of Ceylon, and alfo in Congo (where there is a filver-Mine, and fo much Marble, that the Earth under Ground is thought to be all Mar- ble) and in Peru, about Portovejo in Smaragdina) and in Guiana, near the Coafl of which there is a fmall lOand, called St Maria, which yields abun- dance of Gold, even 100 Pound Weight every Year, if we may believe the Dutch. In the" King- dom of Golunda, there is a Mine which yieldeth precious Stones, particularly Diamonds in abun- dance, but it is not now dug. 10. I N Chili, there are Mines yielding Gold, Sil- ver, and Gems, but the warlike Inhabitants, fet- ting more by Iron Weapons than Gold or Silver, have partly killed, and partly driven away, the Spa- tiiards, and demoliihed the Mines that were but newly begun. 11. THE Ifland Madagafcar abounds in Iron and I'in, with a moderate Quantity of Silver, a little Gold, but no Lead. Wherefore the Natives value Lead Spoons above Silver ones, 12.

IN the IHand o^ Siunatra, it is reported, that there are rich Mines of Gold, Silver, Brafs, and Iron; and that the King in one Year {viz. 1620) received into his I'rearure 1000 Pound Weight of Gold. 13. IN the Philippine \^2ir\6iS^ and in Java, Hi^ fpaniola, Cuba, and others i there are found Mines of Gold, Silver, Copper, and Iron : and in the Mountains of Siajn there is got Gold, Silver, and Tin. 14. THERE are Mines ofSalt in Poland at Poch- nia, four Miles from Cracow -, (where huge Lumps of tranfparent white Salt are cut out ot the Ground^ in Tranjttvama, in the County of 'Tyol in Spain^ in Lejffer Ajia, and in Places near the Cafpian Sea, not far from the River JVolga, over-againft the I (land Kijlowat, where the Ruffians dig their Salt and boil it to a more pure Subilance, and after tranfport it to all Parts of RuJJia. In Cuba, there is a whole Mountain of Salt. All the Mountains in the Ifland oi Ormus, at the Mouth of the Perfian Gulph, are of Salt, which may be gathered in any Part of them, in fuch great Quantities, that the very Walls of their Houfesare built of cryftalline Salt. In a Valley in Peru, about eighteen Miles from Lima to the North- ward, are found deep and large Pits of Salt, where every one may take away what Quantity he plcafcs, becaufe it continually increafeth, and feem- eta impodible to be exhaufted. In Africa there is no other Salt ufed, but fuch as is dug out of Pits, or Quarries, like Marble, of a white, greenifh, or A;h, Colour.

A Wood is a 7millilude of Trees extended over a large Tracl of hand ^ '•johich fpr'ing up -ujiihout plantingy and groiv ivithout being cidlivated. SEVERAL Woods produce only one fort of Trees, from which they receive their Names -, fo that as there is a great Variety in Trees, there is alfo the lame in Vv'oods, viz. Palm Woods, Oak Woods, Ofisr Woods, Beech Woods, &c. Groves and Forefts, are alfo thus diftinguifhed. Divers Coun- tries, efpeciaily thofe more remote, produce diffe- rent Sorts of Woods. In Africa, about Cape Verd^ there are whole Woods or Lemon and Orange- Trees, which the Sailors may pluck for a very fmall Matter. In France, there are whole Woods of Chefnut-Trees : In Ceylon there are Woods of Trees, whofe Bark yieldeth Cinnamon : In the Mo- lucca Iflands, there grow Clove-Trees : In the 5^«- <^.'? IQands, there groweth plenty of Nutmegs: In ^r^zf/ there groweth a hard fort ofVv^ood, which we call Brazil Wood : In Africa, efpeciaily in Nu^ midia, there grow Grapes, of which are made'Rai- fins of the Sun : In the Idand Madagafcar, and in other Places of India, there are Trees which bear Tamarinds : In Mount Lebanon tliere are Cedars, and whole W^oods of them in Japan ; of which they make Mafts of Ships. In Spain, France, and Ital)\ there are whole Woods of Olive and Myrtle Trees. In Germany there are Woods that produce Fir, Oak, Alder, Beech, Pine, Juniper, Maple, Po- plar, Afli, and Elm. THE mofl noted Woods are, the Hercynian Foreft, which formerly overfpread almoft all Germany, and at this Day taketh up large Trafls of Land in feveral Countries, and under feveral Names. I Thp Chap.

Lithuania is alfo overlpread with Woods and Forefts -, from whence large Taxes are raifed for the king of Po- land. PROPOSITION III. Defarts are vafi Tra5is of Land uninhabited by Men; THESE are of two forts, fuch whofe Soil is barren and unfruitful, properly called Defarts ; and fuch whofe Ground is fertile enough, but are never» thelefs faid to be defart, becaufe they are unculti- vated by Men, In Mufcovy^ and in Places near the Cafpian Sea, along the Banks of the JVolga, there are large Trads of fertile and fat Meadow Ground, which lie defart and uncultivated ; in the former Place, by reafon of it's Plenty, and tlie Lazinefs of the Inhabitants : And in the latter, by the Wars of Tamerlane, when thefe Countries were laid wade, and depopulated. But fuch as thefe are impro- perly called Defarts. T H E R E are four kinds of Defarts (properly fo called j viz. fandy Defarts, marfhy Defarts, Jlony Defarts, and heathy Defarts ; which lad produce Woods and Forefts in feveral Places, and are more ufeful and eafy to be cultivated.

HAVING treated of the Divifion of the Earth, and Ws Parts, in the foregoing Chapters i Order requires that we alfo confider the Situation and Divifion of the I'VATERS, which make the other Part of the Terraqueous Globe, and explain fuch of their Properties as belong to Geo- graphy. I N the fecond Propofition of Chapter vii, we divided the Waters into four Species, viz. i . The Ocean and Seas. 2. Rivers and frefh Water. 3. Lakes and Marfhes. 4. Mineral Waters. In this Chapter we fhall Difcourfe of the Divifion of the Ocean. P RO P O SITION I. ^he Ocean., in a continued Extent, encompaffeth the whole Earth, and all it" s Parts, nor is it's Superficies any where interrupted, or altogether broken by the inter pofed Earth ; only a larger TraEl of Sea, or a wider Communication is in fame Places wanting. THE Truth of this Propofition cannot be proved but by Experience, which is chiefly gained M 3 by 1 66 I'he Abfolute Part S e c t. I V^. by failing round the Earth, which had been often attempted and happily accomphfhed •, firft by the Spaniards under Capt. Magellan, who firft difcove- ed the Streigbts, called by his Name ; then by the? ^ EngliJJj, viz. by Sir Francis Drake, Sir 'Thomas Ca- vendiJJj, and others ; after by the Dutch, 8cc. T H E Antients never doubted that the O- cean was thus continued -, for they fuppofed the old World to be raifed above the Waters, and every where furrounded thereby (and fome of them thought it floated). But when America was dif- covered (which is extended in a long Tradl from North to South, and feems to hinder the Conti- nuation of the Ocean) and alio the Ard:ic and Antardlic Continent, then they began to think o- therwife ; for they imagined, that ^;«mr^ was join- ed to ibme Part of the South Continent (which was not unlikely) in like Manner as moft of our modern Geogr.iphers, fuppofe that North America is joined to Grocnland. If both thefe Conjectures had been true, then indeed the Ocean had not en- compaiTed the whole Earth. But Magellan removed all Doubts and Scruples about it, by difcovering, in the Year 1520, the Streights between America and the South Continent, which join the Atlantic to the Pacific Ocean. What therefore the Antients hap- pened to ftumble upon, by a wrong way of ar- guing, we have found out to be a real Truth by Experience. Tlie fame may be faid about Africa ; for the Antients, without any Hefitation, fuppofed it to be bounded to the Southward by the Ocean, and not to be extended fo far beyond the Equa- tor, as it really is •, but when the Portuguefe had fail- ed along the weftern Coaft of Africa, and found it to be extended a great way beyond the Equator, it was queftioned whether Africa could be failed round ffo far as to afford a Paffage to India)y that is, whether Africa was extended Southward or encora- 'Chap. 12. of TJniverfal Geography. 167 encompafled by the Ocean. But this Doubt was alfo removed by Vafco di Gramma -, who, in the Year 1497, firll failed round the mod Ibuthern Promontory of Africa, called. The Cape of Good- Hope ; which Name it had received from John II, King of Por/«^^/, in the Yeaf 1494, when Bar- thel Diaz (who fird returned from it, tho' he did not double the Cape for w^ant of Provifions, and by Realbn of tempeftuous Weatherj had given him a large Account of the ftormy troubled Sea about this Promontory. P RO P S I'TIO N II. The Ocean, taken altogether, is formed by the Land into fever al Portions, of which there are three Spe- cies, viz. I. Oceans, or great Seas. 2. Bays or Gulphs. 3. Streights. 1. THE Word Ocean is taken in a double Senfe, fometimcs for that general CoUetftion of Wa- ters which furround the whole Earth •, and very of- ten for a Part of that Colleftion, v/hich is joined on both fides to other Parts by broad Trads. Thus we fay. The /Illantic Ocean, The German Ocean, The Ethiopic Ocean, and Indian Ocean. We fhall here ufe the Word Ocean fometimes in the later Senfe according to Cuftom, inftead of Sea ; which alfo is a Part of the whole Ocean, becaufe the Word Sea is often ufed in a fomewhat dif- ferent Senfe, as will be fhewed by and by. 2. A BAY, orGuIph, is a Part of the Ocean which flows between two Shores, and is every where environed with Land, except where it communi- cates with other Bays, or the main Ocean. It is very often called a Sea. A STREIGHTisa narrow PafTage, ci- ther joining a Gulph to. the Neighbouring Ocean, M 4 or 1 68 The Ahjolute Part S e c T. IV. or one Part of the Sea or Ocean to another. I'hefe Differences are found in the Ocean, as will appear from what follows. PROPOSITION III. The main Ocean is divicbd into four large and parti^ cular Parts^ which are alfo each of them called Oce~ anSy and anfwer to the four Continents^ or great Ijlands of the Earth. Thefe are, 1. THE Atlantic Ocean, which is placed be- tween the weftern Shore of the old World, and the eaftern Shore of the new World. It is alfo called the weftern Ocean becaufe it lieth to the weftward of Europe. It is heft divided into two Parts, by the Equator •, whereof the one is contiguous to the Hyperborean Ocean, the other to the Icy or South Sea. 2. THE Pacific Ocean, or great South Sea, which is placed between the weftern Shore o^ Ame- rica and Jfia^ and is extended to China, and the Philippine Iflands. 3. THE Hyperborean y or northern Ocean, a- bout the ArSIic Continent. 4. THE fouthcrn Ocean, about the South Continent, of which the Indian Ocean is a Part. OTHER Geographers divide the main Ocean into four Parts, after this Manner: They make the Atlantic one Part, but do not extend it beyond the Equator, where they begin the Ethiopic: They alfo reckon with us the Pacific, and add thereto the Indian ; but we, in our Divifion, have more regard to the four great Continents. Some make but tJiree Parts, viz. The Atlantic, Pacific, and In- dian -, but then they extend the Atlantic further. Let every one ufe what Divifion he likes beft, it is no Chap. 12. of XJniverfal Geography, 169 no great matter which ; for thefe are not made by Nature, but contrived by the Fancy. P RO PO S II'ION IV. S^jne Parts of the Ocean borrow a Name from the Countries which they bound. T H U S we fay the German Ocean, the Britifb Sea, the Indian Ocean, the Gulph of Venice, &c. P RO PO S IT'IO N V. . So?ne Bays are oblong, others broad; fome primary .^ and others fecondary ; the former flow out of the Ccean, the latter out of fo?ne other Bay : and fuch may be called Arms or Branches, Ihe oblong arcy I. THR Mediterranean Sea, which breaks out from the Ocean, between Spain and Barbary ; and runs a long fpace between Europe and Africa, even as far as Syria, Afia-fninor and Thracia. The entrance is called by way of Eminence the Streights. Hence to fail up the Streights, is to vifit by Se2i,Italy, Greece, Syria, Sicily, Venice, and the reft of the Countries that lie upon the Coaft of this Bay. THERE are feveral fecondary Bays, or Arms, which proceed from it, viz. the Adriatic Sea, or Gulph ot Venice, the Archipelago, &c. I T may be reafonably enquired, whether the Euxine Sea be a Part of this Bay. Of which fee Chap. XV. THE Mediterranean had divers Names from the feveral Coafts it reaches ; on the North it hath Spain, France, Italy, Sicily, Sclavonia, Greece, Can- dia, Romania, Afia-minor -, on the South it hath Morocco, Fez, Tunis, Tripoli, Egypt. From whence it is called the Gulph of I.)'t7«j, theTufcan Se^, the Ionian 170 "The Ahfolute Fart Sect. IV, Ionian Sea, the Levant, Sec. It is extended from Weft to Eaft, and receives into it many Rivers. 2. T H E Bailie (or Eaft Sea, improperly fo cal- led) breaketh out from the Ocean between Zeeland and Gotland^ part of the Continent of Sweden, and alfo between Zeeland and Jutland, from whence it flows a long way to the South-Eaft, and afterwards- winding to the northward^ it reaches a prodigious length between the Provinces of Mecklenburg^ Pome- rania, Courland, and Livonia, on the Eaft -, and on the Weft, Sweden and Lapland. It fends out two Arms, viz, x.\\q Bothnic 'Qiy , and the Gulph of i^t;z- land ; to which may be added the Livonian Sea, or Gulph of Riga. It receiveth feveral great Rivers. 3. THE Arabian Gulph, or Red Sea, floweth out of the Indian Ocean between Aden, a Town in Ara- bia, and Cape Mufledon in Africa, having Africa on the Weft, and Arabia on the Eaft. It runs to the Eaftward as far as the Ifthmus of Africa, to the Town of Suez, where there is a Harbour for the 'turkifh Fleet, and receiveth only a few fmall Rivers, but not one out of Africa. It is extended from the South-Eaft to the North- Weft. 4. THE". Perfian Gulph [or Gulph o^ Balfora'] fioweth out of the Indian Ocean, near the Ifland of Or?nus, from the South-Eaft to the North- Weft, between Perfia on the Eaft, and Arabia on the Weft, as fir as the ancient ChaldcBa, where it receiveth the Euphratei and Tigris, joined a little before in one Chanel \ but few Rivers of note befides. 5. T H E Gulph of California, or Red-Sea, runs from South to North, between the Weft of Mexico in America and California, and ends at Tato?jleac, an unknown Part of America. Modern Difcoverers will have California to be an Ifland -, and this not to be a Gulph or Bay, but a Streight or Sea (a). [a] See Note [c) Chap. viii. 6. THE Chap. 12. of Ufiivcrfal Geography. lyi 6. T H E Gulph of Nankin [or Gang] runs north- ward, between Corea and China, towards Tartary, where fome place Tenduc, in the Kingdom of Ca- thaia: others will have Corca to be an Illand. Ic receiveth but a lew Rivers. T O thefe may be added feveral lefTer Bays, fuch as the Gulph Cambaya, &c. Only the two firll of thefe, viz. The Mediterranean and the Baltic^ aftbrd fecondary Bays. PROPOSITION VI. The broad and open Bays arefeven in Nmnber, viz. 1. T H E Gulph or Seaof Mexico, which flows out of the Atlantic Ocean from Eaft to Weft, be- tween North and South America, where it is flop- ped by the long Ifthmus that joins thefe two Conti- nents, and feparates the Atlantic from the Pacific Ocean. It receiveth a great many Rivers, and for Multitude of Iflands may compare with the Archi^ f el ago. 2. THE Gulph of Bengal, or Ganges, ftrikes out from the Indian Ocean, towards the North, be- tween India and the Peninfula of Malacca \ it is bounded by Orixa, Bengal, Pegu, &c. Kingdoms of India, and receives, befides the Ganges, a great many famous Rivers. 3.. THE Bay of Siam, between Cambodia and Malacca, is extended northward to the Kingdom of Sia7n. 4. TPIE JVhite-Sea, or Rujfian Gulph, flows from the Northern Ocean towards the South, be- tween Lapland, and the remote Shores of RuJJia. It ftretcheth out an arm towards Lapland, and endeth at Archangel in Mufcovy •, v/hich is a Mart much frequented by the Englijh and Dutch, It receives feveral great Rivers. 5. THE 172 The Abfoliite Fart Sect. IV. 5. THE Lantchidal Sea, is a Bay between [New- Holland] and New Guinea; two Peninfula's of the South Continent. It is extended fouthward, and terminated at Carpentaria. 6. THERE is another Gulph a little to the weftward of the laft, between [Nuyt's Land] and Van Diemen's Land ftwo Sea Captains, by whom thefe Parts were difcovered). 7. HUDSON'S Bay is bounded by New Britain, New France, New Denmark, &c. and runneth out of the Northern Ocean. To which may be added, Baffin's Bay, the Bay of Bifcay, &c. PROPOSITION VIL Str eights either join the Ocean to the Ocean ^ or the Ocean to a Bay, or one Bay to another, O F Streights we reckon fifteen, viz. 1. T H E Streights of Magellan, tho' they may- yield to others for Antiquity, are neverthelefs, ac- counted very fimous for their exceeding long Reach, thro' which there is a free Paffage from the Atlan- tic to the Pacific Ocean. The Streight is in Length, from Eaft to Weft one Hundred and ten Leagues ; but the Breadth is various, in fome Places two Leagues, one League, and in fome Places but a quarter of a League. Magellan firft difcovered it, and failed thro' it in the Year 1520. Tho' it is re- ported, that Vafcus Nunnius of Valboa, had before {viz. in the Year 15 13) taken notice of it when he failed that Way, to make Difcoveries to the Southward, It lieth in 52 degr. 30 min. South La- titude, between Patagon, a Part of South America on the North, and the Iflands of Terra del Fuego on the South. 2. A little further, to the fouthward, are the Streights of La Maire, which are much fhorter than thofe C H A p. 1 2 . of Univerfal Geography. 173 thofe of Magellan. They have a Part of the South Continent on the Eaft, and the Iflands of Terra del Fuego one the Weft. A PafTage is more expediti- oufly made thro' thefe into the great South-Sea, than the other. They lie in 54 degr. 30 min. South Latitude. 3. THE Streights of Manila, between Luconia and Mindanao, and others of the Philippine Iflands, are faid to be one hundred Leagues in Length, and are a very dangerous PafTage to Ships, by reafon of dreadful Quick- fands in feveral Places. They are extended from Eaft to Weft, and join, in parr, the Pacific to the Indian Ocean, which are alfo not far from thence, joined by broader Streights in ma- ny Places. 4. T H E R E are feveral other Streights among the Indian Ifles, and between them and the Conti- nent j as between Ceylon and India ; between Suma- tra and Malacca ; between Sumatra and Java, &c. 5. THE Streights of Waygats, thro' which there is fuppofed to be a PafTage from the RufTian or North Sea, into the Tartarian Ocean ; but it is fo fhut up with Ice, that it never could be failed thro' by the Europeans {h). It lies between Samoie- da and Nova Zembla. 6. T H E Icy Sea, between Nova Zembla and Spitfbergen, or New Greenland. 7. DAVIS's Streights, between North America and Greenland, have not been yet failed thro' ; there- fore we are in a doubt, whether it be a Streight or a narrow Sea. 8. F O R B I S H E R's Streights, which afford a PafTage from the Atlantic Ocean into Hudfon's Bay. 9. THE Streights of Anian, between North America and Tartary in Afia, through which there is faid to be a PafTage between the Tartarian Ocean, ih) See Note (d) Chap viii, and 174 ^fj^ Abfolute Fart Sect. IV. and the Pacific Sea ; but this is as yet unfettled. They who have failed in that Part of the Pacific Ocean pretend to be certain, thai there are Streights, or Sea, both between America and Tar. tary, and alfo between America and Greenland^ by reafon that for fcven hundred Leagues from Japan towards North A>nerica, the Currents fet ftrongly from the North North- Weft, tho' ihe Wind be va- riable, and blow from other Points of the Compafs : but when they are come within one hundred Leagues of New Spain, thefe Currents ceafe, ^r-A others fiow to the Northward, as if it were to fome broad Sea on the North of New Spain. Alfo in tht^c itw^n hundred Leagues fiiling, Whales are daily feen, and other forts of Fifli, that are known to delight in Streights and narrow Seas, which it is proba- ble, come from the Streights of Atiian, to that Part of the Pacific Ocean ; becaufe they are not found elfewhere [c). However, feverai of our modern Geographers take no notice of thefe Streights, but place a vaft unknown Ocean, between Tartar^ or Corea and America. 1 o. T H E Streights of Gibraltar .^ thro* which the Atlantic Ocean gufheth into the Mediterranean Sea. They lie between Spain and Afirica^ and are about two Leagues over at the flraireft Place, but much longer. The Ancients believed that there (c) It is certain the Sea of Whale paffed from SpUjIyerg Corea and Japan, is annexed thro' tlie neareH: Arm of the to the Tartaric Ocean, and alfo Sea, rather than thro' the more to the Sea of Greenland; be- remote. But be it how it will, caufe that fome Hollajtders af- we may hence fafcly conclude, firm, (who were fhipwreck'd that the Sea which lies beyond upon Corea, a Peninfula of Japan and Spitjherg, is pafla- Chir.ci) that they faw there a ble ; and thro' more perhaps Whale, upon whofe Back lluck than one Arm or Chanel, by a Harpon Iron of Gafcony, which they ccmmunicite. See which not being qucllioned Note [a) Ch^^. \v.\.3.nA Philof. by any, it is mofl probable Tratifail. 2hndgciihy Loiv thorp. to be conjectured, that this Vol. iii.

THE Streights of Denmark [or the Sound] lie between Xeeland and Schonen^ thro' which the Atlantic, in part, flows into the Baltic, where they areftraited. They are about half a German Mile over. Near to this there are two other fmail Streights, the one between Zceland and Funen, and the other called the Belt, between Funen and Jut' land, 12. THE Streights of Bahelmandel, at the Mouth of the Arabian Gulph, near the Sea- Port Aden, thro' which there is a Paflage out of the Indian Ocean into the Red-Sea. - ♦ 13. THE Streights [of Ormus] at the MoutH of the Perftan Gulph, are not properly fo called, becaufe they are but little narrower than the Gulph itfelf. 14. THE Hellefpont, a Streight famous among the Grecians, thro' which there is a Paflage from the Archipelago to the Propontis ; near to this there is another narrow Sea, called the Tbracian Bofpho^ rus, which joins Propontis to the Euxine Sea. 15. T¥i^ Faro, or Streights, o'i MeJJina, be- tween Ital"^ and Sicil-j, MANY have been of opinion, that there were Streights fomewhere northward of Virginia, which is in 40 degr. North Latitude, whereby the Atlantic is joined to the Pacific Ocean, and thro' which they might find a free and open Paffage to China, and t\\Q Philippine Id'xnd.^: but this, in the Year 1609, was in vain attempted thro' Hudfon's Streights. THUS have we explained and pointed out the Parts of the Ocean, diftinguifhed by the Situation of the Land, in like manner as in Chapter viii, we de- fcribed the different Plans of Countries, occafioned by the breaking in of the Ocean. That the Geo- grapher 176 ^he Ahfolute Tart Sect. IV. grapher may keep all thefe in his Memory, it will pot be unferviceable to him to trace out the Peri- meter of the Sea Coaft, and to take a tranfient View of the Shores and Bounds of each Country, and alio how they are fituated, and joined one to another. .

On the North at the Streights of Davis, there is Hudfon\ Bay, from whence follow in order to the fouthward the Shores of New- Britain, New- England, New-France, Firgima, Florida, Mexico, and New- Spain, on the Ifthmus ; then New-Cajlle, Guinea, Brafil, and Patagon, at the Streights of Magellan, where the Shore from running fouthward begins to turn towards the Weft; thence from South to North are extended the Shores of Chilij Peru, New-Spain and New- Mexico, which is bound- ed by the Gulph o^ California •, [where follow the un- known Shores of Mozemhec, &c. (bounded perhaps by the Streights of Anian) which may be contiguous ffor any thing that we know) to thofe of Davii*s Streights.] 3. THE Arcfic Continent is extended to Davis^s Streights, and from thence begin the Shores of Greenland, which run a little to the South, and then return northward to Spiljherg, where they are called the Shores of New-Greenland: thefe are ftretch- ed out over againft Nova Zembla, and the North of Tartary ; from whence the refl of the Shore to Davii's Streights is unknown. 4.

Between Davii's Streights, and Nova Zemhla there is the northern Ocean, and Icy Sea, or Sea of Greenland •, which is continuc^d till be- tween Europe and America^ where it is called the German Ocean, the Britijh Ocean, the French and Spanijh Ocean, and, in the whole, the Atlantic Ocean ; (and maketh three Bays, viz. the Mediter- ranean, the Baltic, and the Mexican Gulph j which, when it comes between the Coalfs of Africa and Brafil, is called the Ethiopian Sea on the one Hand, and on the other the Sea of Magellan : fur- ther to the Eaft, between Africa and the South Con- tinent, is the fouthern Ocean, and between Afia and the fame Continent the [eaftern or] Indian Ocean ; alfo between Afta and South America is the Pacifc Ocean [or great South Sea] which is extended northward to the Streights of Pf^aygats and Anian, and fouthward to the Streights of Magellan [and La Maire] by which it is joined to the Atlantic. It goes under feveral Names along the C-oaft of America, as the Sea of Chili, Peru, Mexico, Califorma, &:c. The Terraqueous Globe is divided into Land and Water. Again Water is divided into the main Ocean, Lakes, Moraffes, and Ri- > vers. The main Ocean is formed by the Earth into three forts of Portions. I. The Ocean, whofe prifne Parts are four. I.

Hence we prove the Superficies to be fpherical, having D for it's Cen- ter (b). This being premifed, the Superficies of all Liquids are thus demonftrated to be fpherical. Let us fuppofe a Liquid at Reft, in the form of EFGH, [fig. 17.) and let the Earth's Center be D, and imagine this Liquid' to be cut by a Plane palling thro' D, fo as the Sedlion may be repre- sented in the Superficies by EFGH. We a^e firft to prove that this Line EFGH is circular, or an Arch of the Periphery of a Circle, whofe Center is D. If it were pofilble not to be c r- cular, then would two I/mes, drawn from D to it, be unequal. Let the unequal Lines D E, D G be drawn, viz. let DG be greater than DE, alfo let the one be the leaft, and the other the greateft that can be drawn from D. Then draw another right Line D F to E F G Fl, bifeding the Angle G D E, fo as to be longer than D E, but fliorter than D G. With this D F as a Radius up- on the Center D, defcribe in the fame Plane the Arch I FK H, which will cut the Line D E pro- duced in the Point I, and the Line D G on this Side G, in the Point K. LIKEWISE with the Radius D L, fomething lefs than DE, upon the Center D, defcribe the Arch LM N within the Liquid in the fame Plane I F K H. Then are the Parts of the Liquid within the Arch LM N continued, and at equal diftances from the Center D : but the Parts between M N are more prefTed than thole between L M , having above them a greater Quantity, and therefore a greater Weight of Water.

AND the Parts of the Liquid within L M, being lefs prefled, are driven out of their Places by thofe within MN which take them up, and put the Liquid in Motion. But it was before fuppofed to lie in this Form at Reft, and ftill : So that the Liquid, by this, will be both at Reft and in Mo- tion, which is inconfiftent. Wherefore the right Lines, drawn from D to EFGH, are not une- qual, but equal \ and fo the Line E F G H is an Arch of a Circle, whofe Center is D. The fame m.iy be demonftrated in all Planes cutting the Su- perficies of the Liquid, and pafting thro' D, liiz. that the Secflion is an Arch of a Circle whofe Center is D. Therefore fince, in the Superficies of Li- quids, all Planes paffing any how thro' D, are found to produce circular Sections, it will follow, from the foregoing Propofition, that the Super- ficies of all Liquids is fpherical ; having the Point D, that is, the Center of the Earth, for their Cen- ter ; as v/ill more manifeftly appear from the Proof of the following Propofition. PROPOSITION II. ^he Sea is not higher than the Land, and therefore the Earth and Water are almojl every where of the fame Altitude^ high Mountains excepted, THE Truth of this is demonftrated by the preceding Propofition. For if the Superficies of the Ocean be fpherical, and have the fame Center with the Superficies of the Earth, and alio if the Sea, near the Shore, be no higher than the Land, neither will the middle of the Ocean be elevated above the Earth, becaufe both their Surfaces make lip the Superficies of one and the fame Sphere. But fome perhaps will not believe the former Pro- pofition, by Reafon of the alTumed Hypothefis ; '? tl'icrefore C k A p . 13. of Unwerfal Geography. 18^ therefore we fliall fhew the Truth of this Theorem, without that, from it's known Effeds. 1. WE know, by Experience, that Water, if it is not hindred, will flow from a higher to a lower Place. If therefore there were about the Shore any Place lower than the middle of the Ocean, the Water would continually fettle from thence to- wards the Shore, and be always flowing, and in Motion J but the contrary is obferved when the Weather is calm. 2. IF the Ocean, far remote from the Shore, was much higher than the Sea Coaft, it might be feen at a greater Diftance than if it were fphe- rical, even over all the intervening Parts that were of a lefs Altitude. But Experience fheweth to the contrary, that when we come from the In- land Parts nearer the Shore, we difcover by little and little the more remote Parts of the Sea, and the nearer we approach the Shore, the further we can fee upon the Ocean. Therefore the remote Parts of the Ocean are not elevated above the Sea Coaft, but are of the fame Altitude with them and the Earth. 3. SAILORS cannot difcover any Difi^erence between their Altitude, at the Sea Coaft, and in the middle of the main Ocean, tho' they ufe the moft accurate Inftruments, which certainly they might, if the remote Parts were elevated above the reft, as a Tower, or a Mountain. For as we can find the Altitude of a Mountain, or Tower, above the Places of Obfervation by Inftruments, fo might they Cif there were any j find the fuperior Altitude pf the middle of the Ocean above the Parts next it, by fuch accurate Inftruments as are now in Ufe. 4. THERE are found, in feveral Places, great Numbers of Iflands, which are, fome of khem, cjctended far into the main Ocean, and others J 86 ^he Abfolute Tart Sect. IV. others almoft contiguous to the Continent. There- fore no Pare of the main Ocean is higher than the Land ; becaufe it is not higlier than the Shores of thefe I Hands. 5. 1' H E Waves upon the Ocean never keep long upon a Heap, but are naturally diffufed 'till they make a fmooth Surface : wherefore it is un- reaionable to fuppofe, that the Water fhould be heaped up tov/ards the middle of the Ocean, 6. I F the Waters in the main Ocean are higher than the reft, why do they not flow into the Chanels of the Rivers, whofe Waters are more deprelTed ? for we find, by Experience, that Water naturally flows trom the Place where it is, to any other that is lower, which is the Caufe of fo many Inun- dations. FROM the whole I think it fufficiently appears, that the Sea is not higher than the Shores ; and but very few Shores are elevated to the Height of the Inland Parts, for thefe are often obferved to rife gradually above the other, 'till they be- come high Mountains : from whence we conclude that no Part of the Ocean is higher than the Su- perficies of the Earth. That the Inland Parts are more elevated than the Sea Shores, appears alfo from the Rife and Currents of Rivers, which, for the moft part, break out, and are diredled, from rhefe Mediterranean Places, towards the Ocean. Thefe Places therefore are higher than the mari- time Parts, becaufe they pour down their Waters upon them. Not but that there are fome Countries which are fituated a little lower than the Surfice of the Ocean, but then they are defended either by the Altitude of the Shores, or by Banks, or long Ridges, of interpofed Ground. Some Coun- tries alfo are not fenced with Banks, becaufe they fear a calm and fettled Sea fhould overflow them, but left, when it is ruffled with Winds and made impetuous. \ • Chap. 13. of U?tiverfal Geography, 187 impetuous, it fhould violently break in upon them. CO ROLL ART. I T is therefore in vain to tell us, that the Sea is higher than the Land, and that by a miraculous Pro- vidence it is kept from overflowing the whole Earth, and caufing another Univerfal Deluge ; for we have fnewed, that both Land and Water are included within our fpherical Superficies, and that mod Parts of the jEarth, at lead the Shores are higher than the middle of the Ocean, which for that Rea- fon cannot overflow Countries, or caufe a Deluge, unlefs the Shore or Banks are wafted, and their Height diminiflied, or a greater Quantity of Wa- ter force them open, or overpower them, and then indeed there may happen an Inundation. Neither is it impoflible, or contrary to Nature, that the whole Earth by fuch Means might be overflowed, as will be made evidently appear at the End of this Chapter. P ROPOS ITIO N m. ^hy the Ocean ^ f^en from the Shore, appears to rife md fwell to a greater Altitude, by how much the more remote it is, THIS is a Deception of Sight, or to fpeak more accurately, in the Eft:imation, which hath brought many into an Error, and by which divers have fuppofed the Sea to be in fome Places feve- ral Furlongs higher than the Land. But it is a wonder they have never taken notice of a common Experiment, which is to be met with every Day, "whf.reby this Fallacy is eafily detedled. If we look UDon a long Pavement, or Area, or upon a row of Pillars, 1 8 8 I'he Abfolute Tart S e c t. I V. Pillars, the Parts that are remote, will appear higher than thofe that are near, and the whole Pavement, or Area, will Icem to be elevated by little and little, as it's Parts are more remote from us, notwithitandiiig, in Truth, it be every where of the fame Alticude. After the fame manner we eftimate the Height of the Sea ; for if we take a levelling Inftrument, and obferve from the Shore the remote Parts of the Sea, we fli.dl find it not to be elevated above us, but rather deprelTed below the Horizon where we ftand. THE Caufe of this Deception is thus explained from Optics. Let the Eye at A obferve a Pave- ment, or the Superficies of the Water, a pretty way* extended a e (Fig. 1 8.). Let the Angle a A e b di- vided into four equal Parts, or Angles e Ad, dAc, c Ab^ b A a^ by the right Lines A ^, A f , Ad, ,' Thefe will divide the right Line ae into four un-^ equal Parts, ab, be, c d^ de, of which the more re- mote will be the largeft, as appears by the Figure, viz, E d larger tharl d c, and d c larger than be, and be than a b. Altho* thefe Parts are very unequal, yet, by a Deception of the Sight, they will be judged to be all equal, and at an equal Diftance from the Eye ; fo that Ab, Ae, Ad, A ^, will feem to be A/, A^, Ah, Ak, where ^/, fg, gh, hk, are equal j and thus the Parts be, cd^ de, feem ele- vated, as if they were fg, gh, hk. O R jljorter thus. Becaufe the Eye is raifed to fee things at a Diftance, and deprefled to view things near, therefore things at a Diftance feem ele- vated, and things near depreffed. Or becaufe we meafure the Diftance of the Parts that are near by the Elevation of our Eye, and therefore they feerii low •, but we cannot do fo by the Parts at a Di- ftance, and therefore they feem not low, but raifed more than they really are. HENCE C H A p . 1 3 • of Univerfal Geography. 189 H E N C E we gather, that tho* the Ocean may feem to be raifed above the Shore, and the more the further off, yet we are not to think that it is really fo. SOME imagine the Ocean to be higher than the Earth, becaufe unlefs it was fo, they think it impoITible that Water fhould flow from it to the Heads of Rivers Cwhich are commonly placed very- high in inland Countries^ fince it never flows, but from a higher to a lower Place. But we fliall dif- cufs this Point, when we treat of the Origin of Springs. OTHERS may infer, that the Pike of Tene- r'lff is not fo high as to be feen on the Ocean at fo great a Diftance as fixty German Miles, or four Degrees, unlefs either the Foot of the Mountain, or the Ocean itfelf, be higher than the Sea upon the Coaft of Teneriff; the like may be faid of other Mountains. What is to be anfwered here appears from Chapter ix, where we treated of the Altitude of Mountains. PROPO s n:ioN iv. To explain the Caufe and Origin of Bap andStreigbts. B AY S, properly fpeaking, are in the Earth and not in the Sea, and therefore they ought to be cal- led the Arms, Branches, or procurrent Parts, of the Ocean. For thofe are more properly called Bays of the Ocean, where it receives Peninfula's, fuch as Malacca^ Jutland, &c. BUT cufl:om hath obtained that the word Bay, fhould, contrary to it*s Signification, belong to the Ocean, and be the ume as an Arm or Branch of it. THESE Bays or Gulphs are thus produced. When a part of the Sea Shore is by Ibme external Caufe 190 The Abfolute Part Sect. IV. Caufe fhattered and rent in two, fo as to leave an Opening, whofe Surface is lower than the Surface of the Ocean, the Water naturally gufheth in be- tween the Cliffs, and is not flopped till it meet with more elevated Ground, by which it is bound- ed, and formed into a Bay. S T R E I G H T S are from this Caufe alfo pro- duced. THE reafon why thefc Parts are now and then fo miferably torn in Pieces, as to admit Inundati- ons (by which Bays and Streights are formedj is the impetuous Motion and violent dalhing of the Waves againft the Shore, being forced by Winds, or fome other Caufe, almoft daily, to wafh away and wafte them : whereby, in procefs of time, the Earth is broken and disjoined, and made unfit to refill the rufhing of the Ocean. But this is more likely to happen if the Shore be low, and confift of loofe and crumbling Earth, eafy for the Sea to work upon, which will with fmall refiftance burft, and make room for a whole Bay of Water, I T is manifeft, that fome new Bays and Streights are thus produced, but we muft not thence con- clude, that all which are at this Day found in the Earth were fo generated : for it is very likely, that a great many of them are of the fame Date with the Earth and Ocean ; and the rather, becaufe none, nor any thing like them, have been produ- ced in the memory of Man. Tho* the ancient Grecians have fuch Fables ; and tell us, that the Mountain Calpe upon the Spanijh Shore, and Ah^le in Africa were formerly joined, bur afterwards fe- parated by Herculei \ from whence thefe Mountains were called Herculei'^ Pillars, and the Streights, Hercuki's Streights (a). IT (a) There are a great many veral other Reafons, to induce Teftimonies of Authors, andfe- us to believe, that Britain was not C H A p. 1 3 • 'rf Vniverfal Geography. 191 IT was a common Opinion of the Ancients, that the Streights between Italy and Sicily^ were made by the Irruption of the Sea, which we do not fo much doubt of : nor do we think it impof- fible, that the hke fmall Streights have been and are ftill generated. Streights alfo may be turned into Bays, and Bays into Streights -, as if, for Example, the Mouth of the Streights of Magellan or Manilha^ fhould be flopped on the one fide or the other, they would be changed into long Buys : or if (on the other hand) the IJlhmus between Africa and y^fia^ fhould be removed, then the Red-Sea would be joined to the Mediterranean, and they both be- come Streights, and afford a PafTage to the Indian Ocean. PROPOSITION V. Whether the Ocean be every where of the fame Altitude, I T appears from the firfl Propofition, that the Face of the Ocean in it's natural Situation, and when no ObflacLe hinders, is every where of the fame Altitude, having, as was there proved a fpherical Surface, and being conccntrical with the Earth : but it may be here doubted, whether for fome Reafons, it may not in one Place be higher than in another ; which is very worthy of Obfervation, and of great Moment to be well underflood, by not an Ifland from the Begin- every Day on both Sides, wa$ ning, but was formerly joined wore away and waited.

SEVERAL will have both the Sea and Land to be higher towards the Northern Parts, than about the Equator, and this was JriJiotle*s Thought fin Lib. 2. Chap, ii. de Ccelo) (c). The Reafon they bring for it is, that the Ocean feems to flow from the Northern Parts as from a Fountain ; but this does not prove it's fuperior Altitude there : for whether the Northern Countries, or rather the Nor- thern Chanels, be higher or lovver than the Cha- nels near the Equator (as is yet doubtful, or at lead not fufficiently proved from that Motion which is not generally found in all the Northern Parts) it does not follow, if they were fo admitted, that the Ocean is there higher ; becaufe that to lower that fuperior Height, and to make the other equal with it, the Ocean is conftantly flowing towards the Equator. Arijlotle in the forecited Place adds ano- ther fabulous Reafon, taken from the Poets, which is not worth an Anfwer, viz. that the Sun when it fets, hides icfelf beyond the great Bulk of the Nor- thern Regions. THIS Opinion of the fuperior Altitude of the North Pole, feems to arife from hence -, that when we turn our Faces that way, we imagine the Pole to be raifed above the Horizon of the Place we are in, and therefore judge the Countries thereabouts to be elevated above us. SOME think the Indian Ocean to be higher than the Atlantic^ which they endeavour to prove from the Flux of the Sea in at the Streights of Gi- braltar^ znd of tht Arabian Gulph : but then, this doubt is to be confidered, whether the Altitude of " Bays, efpecially in their extream Parts, be the lame (c) The Earth and Ocean are higheft about the Equator. See the Note [i) on Chap. iii. with C H A p. 1 3 • of JJniverjal Geography, 193 with that of the Ocean, or leis •, and chlefiy thofe Bays which are joined by very narrow Sircights to the Ocean, T H AT the Atlantic and Indian Ocean are higher than theextream Parts of the Mediterranean^ near Egypt and AJia minor^ none need doubt ; for unlefs the Streighcs of Gibraltar (where the Atlantic floweth into the Mc'diterranean) were fomething lower than the Ocean, there would not be fuch a ftrong Current there as it is. Perhaps at the Streight's mouth there may be but little difference j but then further, to continue the Flux all over that large Trad: between Europe and Africa, the depref- fion of the Bay mull by Degrees be greater, other- wife the Water could not flow when it is lb often obftrufted by Rocks, Iflands, Peninfula's, and o- ther Obftacles, which repel the Current of the Wa- ter, and diminilh the Force of the Influx. We need not doubt of this, if it be true what is record- ed of Sefojlris, Darius, and other Kings of Egyft^ by fome Authors of good Credit, how they at- tempted to cut a Chanel between the Red-Sea and the Nile, that out of the Indian Ocean, and thro' the Red- Sea, they might fail that Way from the Mouth of the Nile into the Mediterranean ; which would be of great Advantage to Egypt and other Countries upon the Coaft of the Mediterranean. But they were forced to defifh from this Enterprife, when the Red-Sea was difcovered by the Artificers CO be much higher than the Inner Egypt. If there- tore the Red-Sea be higher than the Land of Egypt ^ it will be alfo higher than the Water of the Nile and the Mediterranean icfelf, into which the Nile flows •, and confequently the Red-Sea, and alfo the Indian Ocean, are both higher than the Mcditerra^ nsan, efpecially thefurthefl: Parts of it about Egypt, Romania, and the Archipelago, V O L. I. O M ORE- 194 ^^^ Ahjolute Fart Sect. IV. MOREOVER, other Kings of Eg^pt of old, and of late the Egyi4iaii Sultans, and Turhjlj Em- perors, had frequent Confultations about cutting through that Ijlhtnus that joins Ajrka to /-///^, and feparates tlie Miditerranean from the Red-Sea \ but the Reafon, as we are told, why they did not fet about it was, that the Indian and Red- Sea were found to be much higher than the Shorts of the Mediter- ranean : and therefore it was feared, that the /^^i- •S(?^rfhou Id overflow them, efpecially £^)'/>/, which is reckoned by every one to be a very low Coun- try. I'll AT the Red Sea h higher than the Medi- terranean appcareth troni thele Obfervations ; but tliis, not without Caule, may be doubted by fome, bccaufe they are both Bays, the one of the Atlan- tic and the other of the Indian Ocean. Therefore to give a plaufible Reafon, why the one fhould be higher than the other, it will not be amifs to con- fider, that tho' they are both deprefled more than the Seas from which they t^ow •, yet the Difference is lei's fenfible in the extream Part of the Red-Sea, which is nearer the Indian Ocean, than the extream Parts of the Mediterranean are to the Atlantic. For I cannot think that the Indian Ocean is higher than the Atlantic, as Ibme imagine. I F therefore the Illhmus was cut through, no doubt but a great Quantity of Water would flow from the Red-Sea into the Mediterranean •, but I can- not think fo much as to bring Egypt, and other Places about the Levant, into danger of being over- flowed : becaufe if the Indian Ocean poured in more Water, the Atlantic, woukl very likely emit lefs, that fo they might each retain the fame Altitude in Proportion. ■ '"'•-.'" ' BESIDES this, I tuppofe the Sultans of Egypt an4. tlie I'urks, were induced by other Political -iA/. . w\ - , v^ Caufes Chap. 13. of Univerfal Geography. 19^ Caufes and Reafons to omit cutting through this Ifthmus. THE firfi: fcruple was no doubt the greatnefs of the Work, for it would be no Anall Labour and Expence to cut thro' an lllhmus, whofe Breadth at the narroweft Part is at leaft forty German Miles, and the Earth rocky •, befides there muft have been Dams and Wears made in feveral Places, which could not have been done without PKillful Work- men, which thofe Nations have always wanted. THE fecond Reafon was, becaufe they fup- pofed the Chriltian Nations in Italy ^ Venice, France^ Spain, Sec. would receive greater Benefit than they themfelves from this Canal, by failing thro' it to Perjia and India, and bringing thence thofe pre- cious Commodities, which the Turks and Egyptiam at prefcnt carry at their own Prices by Land, and for which they receive large Duties, which bring confiderable Revenues into the Grand Seignior's Coffers. See Maffeus^s Hiftory of India, Book iii, where he tells us, how much the Sultans of Egypt were formerly offended at the Portuguefe failing and trading into India. A third Caufe why they neglefted this was per- haps, becaufe they knew the Chriltians excelled them in Navigation ; and were theretore afraid left they fhould invade thofe Streights, and the adjacent Countries, or even Medina itfelf, the Sepulchre of Mahomet. For a confiderable Fleet v/ould in a fhort tim.e tranfport a great Army of Men, and all neceffary Provifions from Europe to Arabia^ by this Canal. BUT Alphonfus Albuquerce, Governor of the Portuguefe Indies, was of another Opinion, when he had intended to have turned the Nile from Egypt, by cutting a Chanel thro' Ahyjjinla (which borders upon Egypt, only a few Delarts interpo- fing) to the Red-SeUj that by this means he migKt O 2 reader 196 "The Ahfohite Fart S e c t.

THUS far, concerning the Altitude of the Mediterranean compared with that of the Red-Sea^ ^tlantk^ and Indian Ocean. We were obliged to explain it •, becaufe from thence fome take Oc- cafion to argue the unequal Altiiude ol Ibme Farts ot the Ocean. "BUT ihelc things may be comfirmed by ano- ther Example, if we may compare groat I'hings with fmall. I'he German Ocean, which is a Part ot the Allantk^ running between Fnejland and Hol- land^ forms a Bay •, which tho' it be but fmall, in comparilbn ol thefe iamous ones juft now men- tioned, yet it is called a Sea, and watereth Am- jlerdam the Capital of Holland. Not far from thence is the Lake of Ilnrlem, which is alfo called the Sea of Harle^n : this is as high as the foremen- tioned Bay, and fends out a Branch to Lc\den\ where it is divided into feveral lefTer Canals. And becaule neither the Lake nor the Bay overflows the bordering Country fwhen they are fettled and at quiet, and they have Bulwarks provided againft a Storm) it appears that they are not higher than the Lands of Holland. But that the German Ocean is higher than thefe Countries, hath been experien- ced by the Inhabitants of he-^den., when they under- took to cut a Canal from their City to the German Shore, near the Town of Caiwic^ which is about two Holland Miles in Length •, fo that the Sea be- ing let in, they might fail into the German Ocean, and from thence to other Countries. But when they had finiflicd a great Part of it, they were for- ced to leave ofi^, having at length found, by Ob- fcrvation, that the German Ocean ^vas higher than the Ground between it and Leaden •, from whence the Place where they left off is called by the Dutch, lUt malic Gal. i. e. unprofperous. Therefore the .3 German C H A p. 1 3 • rf Ufihcrja! Geography. i gj German Ocean is fomething higher than [the Zuy der Zee or] the Bay of Holland. BUT all Bays are not deprefled below the Ocean, for thole that run out into the Land at broad and open Pallages, fuch as thofe o'i Mexico^ Bengal^ &c. are, without doubt, of the fame Al- titude with the Ocean itfelf : tho' I know the Spa- niardi doubted this (whether the Pacific Ocean was higher than the Bay of Mexico) when they confult- ed about cutting thro' the Illhmus of Panaina^ that they might with more Expedition fiiil to Peru, China, and the Indian Iflands. But bsfides this Sufpenfe, we underftand that they had a Political Reafon for not doing it •, they were afraid left the Englijh, Dutch, and other Nations fhould make ufe of it, and lie in wait at the Entrances, or in- vade Peru.

Whether the Indian, Atlantic, and Pacific Ocean are of the farne Altitude, or the Atlantic be lower than the other two. 2. Whether the northern Ocean, near the Pole, and within the Frigid Z,one, be higher than the Atlantic. 3. Whether the Red-Sea be higher than the Mediterranean, 4.

But there isfuch a Nicety required in making thefe Try- als, and the time of Obfervation is fo Ihort, that it is very rare to find the true Depth by this Me- thod. However it appeareth, that the Depth of the Ocean is every where finite, and not extended to the Antipodes •, becaufe if two Portions of Earth were divided by any Part ot the Ocean, which might be continued thro* the Center to the oppo- fite Side of the Globe, unlefs they were fupported with Arches, they would immediately fall together at the Center, becaufe the Earth is heavier than the Water. Befides, the whole Bulk of Earth and Wa- ter is finite and fpherical ; and therefore the Depth of the Ocean cannot be infinite. MOREOVER, from the Obfervations of the Depth in divers Places, it is manifeft, that the Cha- ttels in Depth are nearly equal to the Mountains and inland Parts in Elevation, that is, as much as the one is raifed, fo much the other is deprefled, and as the Altitude of the inland Parts is gradually increafed from the Shore, fo is the Sea deeper and deeper towards the Middle of the Ocean, where the Depth is for the moft part greateft.

The Phi- lofophcrs ot old werealfo of Opinion, that the Sea iflued forth at feveral Springs ; neither could the Magnitude nor the Perpetuity of it's Bulk convince them of their Error, for they faid, that it was con- veyed by fubterraneous Fillures to thefe Fountains, which therefore kept continually flowing. Ariflotle fBook ii. Meteor. Chap. \\.) endeavours to prove the contrary, and to refute the Arguments of the Ancients, but fays very little to the Purpofe j we think thefe following will be more efl^edual to dif- prove them. If the Ocean have Springs they muft either be in the raifed Parts of the Earth, or in that Part which is covered with the Ocean, that is in the very Chanel of the Sea. That there are no fuch upon the dry Land is apparent, becaufe there were never yet found any •, and to fay that they are in the unknown Countries towards the North or South Pole is to take a Thing for granted with- out any manner of Reafon for it, becaufe mofl: of thefe Countries are covered with Ice continually, and as many as are difcovered of them afix)rd no Springs at all. Neither can they pretend to fay that they are in the Chanel of the Sea -, for if they were, they would be no further diflant from the Center than the Ocean itfelf •, and therefore the Water in them would not flow, but be at Reft, becaufe it is againft Nature that it (hould afcend from a lower to a higher Place •, and the Springs of all Rivers are higher than the Waters they emit. Some indeed may objed that this Motion is vio- lent, becaufe that the Bottom of the Ocean, being ])f*rforated into Dufts, Meanders, Fiflures, or Ca- 2 nals, J H A p. 13. of Univerfal Geography. 203 rals, Cwhich you'll pleafe to call themj is not ter- minated in the Earth's Bowels, but exrended to a- nother Fart of the Bottom of the Ocean by more Intercourfes than one ^ fome of which convey the Water one way, and fome another, io that it iffu- eth out of each, as if they were fo many Springs. And fince (fay theyj it is not contrary to Reafoii to fuppofe many of thefe Padliges or Intercourfes, nothing hinders but that there may be alfo as many Springs in the very Chanel of the Ocean. But thefe are all vain Fancies, and no way agreeing with the Nature of Water ; for tho' the Water be continued thro' thefe Orifices, it will not flow thro' one or the other, but be at Reft, unlefs it be ur- ged by fome external Caufe i and tho' it be prefTed by the incumbent Water on this fide the Intercourft, it will not difcharge itfelf at the other ; becaufe it is as much prefTed by the incumbent Water there, which keeps it in jEquilibrio, and at Reft, as may be proved by Experiment thus : Let A B C D {Fig. 20.) be a Veffel full of Wa- ter, and A B it's fpherical Superficies. Let R P E F be a hollow Beam of Wood, lying obliquely un- der Water, fo that the whole at g under A may be higher than the Hole at h under B. Then the Water will flow in at both ends of the Beam 'till the hollow Part be full -, but there will be no Flux at either Orifice ; not at g becaufe it is higher nor at h, becaufe, tho' it be lower than g, yet the greater Weight of the Water about B will ftop the Flux (e). ^fj For, by the Laws of Hy- of Water under A, and it's droftatics, the Weight of the own relative Gravity in the greater Column of Water un- declining Bore is to prefs it f Vniverfal Geography, 23 r PROPOSITION II. iVhen an"^ Part of the Ocean is moved, the whole is moved, or all the other Parts of the Ocean move fucceffivel-j j but the Motion is greater by how much it is nearer the Part firft moved. BECAUSE when one part of the Ocean is moved, it neceflarily changes it's Place, and leaves that it was in, to be taken up by the Water that was next it •, whofe place is again fupplied by the Water next that, and fo on. But the Motion be- comes lefs in the more remote Parts •, becaufe that there the Water was firfl moved, the next to it rufhes in, not from one Part, but all round about i fo that it leaves a round Space like the Periphery of a Circle, which is fupplied from a larger Peri- phery, and that again from a larger, and fo on. But the greater the Periphery is from whence the Water flows, the lefs is the progreflive Motion in- wards, being difl:ributed into a larger Space. Juft as, when a Stone is thrown into the Water it forces it into a Round, and that forces the next Water to it into a larger Round and fo on ; and the further thefc Peripheries are from the Immer- fion of the Stone, their Motion is diminifhed and lefs fenfible ; and the* there may at laft feem to be none all, yet there will be flill fome very fmall Undulation, except it be hindered by another Motion of the Water.

THIS Motion of the Sea is manifeftly per- ceived by thofe that fail from India to Madagafcar, and Africa •, alfo in the Pacific Ocean between New- Spain and China, and the Moluccas ; likewife in the Ethiopic Ocean, between Africa and Brafil. THUS the Currents fet ftrongly, and run with a rapid Motion, from Eaft to Weft, thro* the Streights of Magellan -, which induced the firft Difcoverer (whether Magellan, or fome other be- fore him) to conjedure, that there were Streights thro' which they might fail out of the Atlantic into the Pacific Ocean. Ships are carried by the Currents, from Eaft to Weft, thro' the Streights of Manilha, and alfo thro' the little Chanels be- tween the Maldivies. The Sea runs impetuoufly into the Gulph of Mexico, between Cuba and Tu~ catan, and flows out again, thro* a rapid Chanel, between Cuba and Florida. There is fo rapid a Flux into the Gulph of Paria, that the Streights are called the Dragon's Jaw. This Monon is alfo remarkable at the Land of Canada. The Sea feems to run oiit of the Tartarian Ocean thro* the Streights of IVaygats, as appears by the fetting of C H A p. 1 4« rf TJnlverfal Geography. 23^ of the Current, and the great Flakes ot Ice which are commonly found in tnefe Sireights. Upon ihe northern Coaft of America^ the Pacific Ocean flows towards the Streights of Anian \ there is alfo a Current from Ja^an towards China ; and another from Eaft to Weft, thro* the Streights of Ma- cajfer. In fhort, the whole Atlantic Ocean makes towards the Shores of America^ and the Pacific from them, as is moft remarkable about Cape CorrenteSy between Panama and Lima. PROPOSITION VIII. The JVinds frequently change the general Motion of the Sea, efpeciaily thofe called Periodical PVinds, or MonfuonSj which we Jljali treat of in Chapter xxi. BECAUSE thefe Winds blow moft frequent- ly from the North or South, or from other col- lateral Points, they muft needs obftruft the ge- neral Motion ot the Sea, which is from Eaft to Weft, and caufe it to turn afide, from the Weft, towards the North- Weft, or South- Weft. And even the conftant, or Trade- Winds, v/hich fel- dom blow diredlly from the Eaft, but from fome other collateral Points, change this general Motion of the Sea in many Places. Alfo the North Winds make a moft fenfible Difference in this general Motion in the northern Ocean, where thefe Currents are not ftrong, except in a few Places. PROPOSITION IX.

Some Copernkans fas Kepler, i^c.) altho' they acknowledge the Moon, to be the prime caufe ol this Motion, yet they make the Motion of the Earth not a little contribute to it, by realbn that the Water, being not joined to the Earth, but contiguous only, cannot keep up with it's quick Motion towards the Eaft ; but is retard- ed and left towards the Weft ; and fo the Sea is not moved from one Part of the Earth to another, but the Earth leaves the Parts of the Sea one after another. OTHERS, who are fatisfied with neither of thefe Caufes, have recourfe to the Moon •, which they will have to be the Governefs of all Fluids, and therefore to draw the Ocean round with her from Eaft to Weft. If you afk, how fhe per- forms this ? They Anfwer, it is, by an occult Quality, a certain Influence, a Sympathy, her Vicinity to the Earth, and fuch like. It is very probable indeed the Moon, Ibme way or other, caufes this Motion, becaufe it is obferved to be much more violent at the New "and Full Moon, than about the Quadratures, when it is, for the moft Part, but fmall. THE ingenious Des Cartes mechanically explains how the Moon may caufe this Motion, both in the Water, and the Air. He fuppofes, according to his general Hypothefis, that there are an infinite number of Atoms, which re- volve about the Earth, and fill up the Space be- tween Chap. 14. of Vnherfal Geography. 237 tvveen it and the Orbit of the IVIoon, fo as not to leave any Vacuum ; this Space he calls the Earth's Vortex (b).

Now, fays he, if there was no Moon in the Vortex BADC, it's Particles would without any Impe- diment revolve about the Center T •, but fince the Moon is there, the Space, thro' which the cele- ftial Matter flows, is narroweft between B and T ; therefore this Matter flows fwifter between B and T, and by that means prefixes both the Super- ficies of the Air at 6, and of the Water at 2, more than if the Moon had not been in the Dia- meter of the Vortex B D : and becaufe both the Air and the Water are Fluids, and eafily give [b) The Flux and Reflux of the Sea, which Des Cartes has endeavoured to explain, by an imaginary Plenum and Vor- tices, may be more eafily and fully explained upon other Principles (as fhall be fhewn hereafter) ; for thefe are mere f iflions, and no way agreeable to Nature and Motion, as ap- pears from the following Ar- guments. I . U fome \'acuities were not fuppofed to be interfperfed among the Particles of Bodies, it would be very hard to con- ceive how Motion could be any way performed. For if we fuppofe every Place to be abfolutely full, a fmall Body cannot move ever fo little, with- out moving all the Bodies in the Univerfal, and whither, or to what Place, they Ihould move, when all Places are already fnU i^ not eafv to conceive. * 2.

And while the Earth is turned from E, by F, towards G, or from Weft to Eaft, the fwelling of the Water 412, and of the Air 856, which is now higheft at E, moves by little and Httle to the weft- ward, and in fix Hours time is higheft at the Part of the Earth H, and after twelve Hours at G. Hence it follows, that both the Water and the Air are perpetually moving from Eaft to Weft. Thus far Da Cartes, The ftrefs of his Demon- ftracion lies here; that the Earth EFGH, and "Water 1^34, are revolved round the Center T, together with the cel.-ftial Matter in the Vortex, be- tween B \DC and 6587 ; but the Moon, being in B, makes the Space B6 narrower, whereby the ce- leftial Matter is fqueezed thro*, and in it*s Paflage preiTes the Air and Water below B, at 6 and 2, towards 5 and 1 , and while E pafles beneath B, it is preflcd towards H and F, and fo round. Nor doth this celeftial Matter, ftrained between B and 6, rebound upward being fupprefted, be- caufe all things are full of Matter, And tho' it prefs the Air and Water from 62F not only towards the Weft E 15, but alfo towards the Eaft 73G, yet becaufe the Parts between F and G, to the eaftward, are, by degrees, removed from the Streights B6, and the Parts towards E, to the weft ward, do more and more approach it, there- fore this Force is chiefly received by thefe. BUT the following Particulars feem wanting in this ingenious Explanation. I. IT fliould then follow, that the Sea would fettle when the Moon approached it, and rife in thofe Places that are diftant a Qu.:drant, or fix Hours, from it, 'v'lz. it would tall at 2, where the Moon is vertical, and rife at 6. But this is contrary to Experience ; for at 2, under the Chap. 14- of Univerfal Geography, 239 the Moon, it rifes, and at i it falls. How this Abfurdity may be avoided, we fhall fliew in the foJ lowing Propofition. 2. IT is not plainly fhewed (Des Cartes himfelf totally omitting ir) why, when the celeftial Matter in the Streight B6 prefTes the Air at 6, and the "Water at 2, it is not equally moved towards G'^y^ feeing that the Earth, and Air, and Water, are all carried that way, as well as the celeftial Matter, which fliould therefore enforce the Air and Water rather towards the Eaft than the Weft, 3. THE Moon approaching any Sea, there fhould a ftronger Wind blow from Eaft to Weft: than at other Times ; but this feldom happens. , 4. I T is more likely that the Sun ftiould caufc this Motion of the Air, and thefe conftant Winds, becaufe in many Places they are obferved to blow freflier a little before, or about, Sun-rifing, when it is diftant a Quadrant from the Vertex of the Place {c). Thefe things are worthy to be confi- dered in the aforefaid Explication, not to fay any thing for or againft the Hypothefis itfelf. I very much doubt whether this Motion of the Sea has any relation to the general, or Trade- Winds ; becaufe thefe Winds, in the Torrid Zone^ are conftant •, and therefore fhould caufe the Mo- tion of the Water to be conftant alfo (d). Indeed when the Wind blows harder the Motion is per- ceived to be greater ; but this is no Argument that they have a Dependance, or proceed one from another.

This laft is excellently explained by Des Carles^ s Method •, for fince the Moon is nearer the Earth at the New or F"ull than when fhe is in the Quadratures, the Paffage for the celeftial Matter, Bb, is then made narrower, and therefore the Prefilire is greater (e). I F any fliould alledge, that perhaps the greater Light of the Moon, at Full, caufes the greater Intumefcence -, I anfwer, that at the Change all her Light is taken away -, which fhews that Light is not the Caufe of this Motion, but rather that Prefilire of Des Cartes, which we fhall further ex- plain below. PROPOSITION X. The fecond general Motion of the Sea is ii's Flux and Reflux, by which, in about twelve Hours and a half^s Time, the Water is found to flow towards the generality of Shores, and to ebb back again, viz. to flow when the Moon approaches the Meridian t Circle above or below ; and to ebb when it departs from thence towards the Horizon.

F O R the Shores of Bays, and the Chanels of Rivers, where this Fhix and Reflux is chiefly obferved, more than in the main Ocean, are di- vers ways extended ; feme from Weft to Eaft, as the Mediterranean Sea, and others from South to North, as the Arabian Gulph, ^c. And in all thefe the Water flows thro' the Strcights towards the furtheft Point of their extent ; and therefore in different Bays, this Flux ot the Ocean tends towards divers Points of the Compafs. We muft therefore firft be refolved, whether this Flux, or Motion, tends indifferently to any Point, or only ■ obferves two, viz. the Weft in flowing, and the Eaft in ebbing ; or even only the Weft in both ebb- ing and flowing? In my Opinion the laft is trueft, viz. that the whole Ocean is moved from Eaft to Weft, both in it's Flux and Reflux, and that the difference is, that in it's Flux it is moved with greater violence and in a greater Quantity : but in it's Reflux (or more properly it's Dcflux) tho* it be not moved a contrary Way, yet it feems to be fo, becaufe there flows a lels Qtiantity of Water. HENCE we may determine, that the Flux and Reflux of the Sea is no way diftinft from that general Motion, which we explained in the former Propofition, whereby the Ocean is perpe- tually moved from Eaft to Weft -, for it is only a certain Mode or Property of that Motion. And therefore if this Motion be obferved, and rightly confldered in the main Ocean, where it is not ob- ftrufted, we fhall find it not to be fo much a Flux and Reflux of the Sea, as a Flux and De- flux, or fthat we may diftinguifti, by proper Terms, the Quality of the Motion or Flux from the Mo- VOL. I. R tion 242 ^be Ahfolute Fart Sect. IV. tion or Flux itfeli ), it is inoft aptly called tiie Swelling and Swaging ot the Sea. FOR the Sea perpetually flows from Eaft to Weft, and only ieems to flow back again, when it's more violent Force is flackened and wafted, which a little before was quickened and augmented. But this is called the Reflux, becaule the Sea ieems, on Shores and in Bays, to approach and retire by lits, which is not owing to the quality of the Mo- tion itfelf, but to the Situation of the Shores and Bays, which requires that the Water fhould fall back to the contrary Point ; but the fettling of the Sea in general doth not proceed from the Situation of the Shores, but from the quality of the Motion of the Water. BUT the Motion of the Sea can by no means be eftimated by it's approach to the Shores, for whatever this Motion be, or to what Point foever it is made, it will always fluftuate towards the Shores ; which happens by reafon of the fluid Na- ture of the Water. T H AT the Sea moves towards the fame Point, that is, from Eaft to Weft, both in the Flux and Reflux for Swelling and Swaging), and never moves the contrary way, appears from the fol- lowing Obfervations. i. In the main Ocean be- tween the Tropics, there is no other Motion per- ceived than this from Eaft to Weft. 2. In Streights that join the Parts of the Ocean and run directly Eaft and Weft, as the Streights of Magel" Ian, Manilha, Java^ and others among the Indian Iflands •, in thefe, I fay, the Sea rifes and fettles in 1 2 Hours Time, but in fettling it doth not flow back out of the Streights to the eaftward ; but is carried by other Paflages, ftill to the weftward ; which is a plain Sign that this Ebbing and Flow- ing are not two contrary Motions, but a Modifi- cation of the general Motion from Eaft to Weft. So Chap. 14- of Unhcrfal Geography. 24-7 So that Scaliger and all the reil are deceived, who reprefent this as a double Motion to and again. IT is to be underftood, that when we fay this Motion is from Eaft to Weft, we do not mean punduaily the two cardinal Points, but include all their Collaterals, even to the North and South Poles, towards which however the Motion is weaker. PROPOSITION XI. To explain the Caufe of the Swelling and Swaging of the Sea, vulgarly called it^s Flux and Reflux {f). THERE (f) Sir Ifaac Neivtojz moll fuccefsfully explains as well the Flux and Reflux of the Sea, as moil: other Appearances of Na- ture, from his u?iiverfal Princi- ple of Gratify or Attraftion. Gravitation is a certain Force im- printed on all Bodies by the Au- thor of Nature, by which they mutually endeavour to accede ; but how this Force is exerted we know not. Thus the Globe of the Sun and Planets gravitate mutually towards each other in proportion to their feveral Mag- nitudes, and Dillances from one another. As to this Earth of ours, it hath but little Commu- nication with the other Planets, whofe Bodies are too fmall to affeft us much, at fuch a vail Dillance; only the Sun and Moon are refpefted by it, the one becaufe it is placed fo near us, and the other by reafon of the Bulk of it's Body; which tho' it be at a vaft Dillance, yet afts with a ilrong attraftive Force. For a Body is more forcibly attracted by how much the Dillance of the Attrahent is nearer, or it's Bulk greater. I. Thus J Let L (Fig.z-},.) be the Moon, fuppoled to be above any Part of the Earth, covered with the Ocean ^sh; it is evident that this Place, being nearer ihe Moon than any o- ther Part of the Earth, is more flrongly drawn thereby, and fwelleth up towards it : But the Water in the Place a be- ing diametrically oppolite to the Place b, and further off from the Moon than the reft of the Earth, hath a lefs Tendency towards it than the other Parts; and therefore, being left as it were by the Earth, is lifted up, or fwelled, the contrary Way in a. Hence the Water flowing from d io e towards A and B, makes two Protuberances in the Ocean, the one in B direflly under the Moon, the other in A juft oppofite to it; and thefe always Ihift and accompany the Moon in it's feeming Motion R 2 about 244 I'he Ahjhliite Fart Sect.

THERE is no Phjcnomcnon in Nature that hath lb much txerciled and puzzled the Wits of Philofo. about the Earth, and occafion thereby two Floods and Ebbs in the fame Place, every five and twenty Hours. 2. Of thefe two Tides that happen in the Time of one di- urnal Revolution in any Place, that is the greateil:, wherein the Place cometli neareil the Eminence of the Water A or B. Thus, in fuch a Figure as the laft, let, Vp (Fig. 24.) be the Poles, JE Q^the Equator, FG a Parallel to it, which a- ny place defcribes by it's diur- nal Motion ; it appears that the two High-waters happen in the Place, when it is fituated in G or F, having the Moon in the Aleridian; but the higheft Tide is found in the Point G, wliich comes nearcft the Eminence of the Waters in B. It further appears from the F'igure, that the Moon, in the Time of the higheft Tide, is above the Hori- zon of the Place, if Ihe is on the famefideof the Equator with the Place itfelf: butif fhe decline the contrary Way, fhe is under the Horizon in the Point A, at the Time of the higheft Tide. For Example, in Europe x\\e ^'mn\?\ Tides are the higheft of the two when the Moon is found in the elevated Semicircle of the INIeridian, or in the Northern Signs of the Ecliptic; but the loweft when llie is in the South- ern Signs. Moreover, the Height of the Tides is varied generally all over the Earth, accordingtotheday of the Month and the time of the Year. 3 . F"or, becaufe the attractive Force of the Sun reaches the Earth as well as that of the Mc's?r, when both thefe Forces confpire, or are united, they raife the Waters higheft, and make what we cdWSpring Tidts; but when the 5"«« deprefles whnt the Moon heaves up, then hxip- pen the loweft or 'Neap Tides. Thus we obferve higher Tides when the Sun and Moon in Con- jundlion or Oppofition, are right over any Place B, or diametrical- ly oppofite over A and B, than when they are in the Quadra- tures, 'vi'n. when the Sun is in the Point FI or I, and the Moon in the intermediate Point A or B. But the F'orccof the Sun is final 1 compared \\ ith that of the Moon ; becaufe the Semidia- meter of the Earth CB, by which the Water in B is nearer the Sun than the Center C, is fcarcelenfible, if compared with the immenfe Diftance of the Sun. 4. Since the Eminences of Water are carried round the Earth by the diurnal Motion, the Motion, Agitation, and Heighth, of the Tides, are the greater, the larger the Circle is in which the Waters revolve. So the Moon being in the Equino- ftial, and leading about the two oppofite Eminences of Water in theEquator,makcsgreaterTides [co'tcris paribus) than when fhe ib in the Tropics.

PROPOSITION XXII. ^he Winds very often hinder, or promote, the Courfe of the Tides in all Places ; and not only the Winds that blow in thofe Places, but even thofe in others may have the fame Effe^. THE Truth of this Propofition is fo clear, that it needs no Demonftration. PRO PO S Il'ION XXIII. JVhen any Part of the Ocean hath a proper, or par- ticular. Motion, it is called a Current. Currents are various and direHed towards different Parts of the Ocean, of which fame are conftant and others periodical. To enumerate the moft famous conftant ones, I. THE moft extraordinary Current of the Sea is that by which Part of the Atlantic or African Ocean moves about Guinea from Caps Verd towards the Curvature or Bay of Africa^ which they call Fernando Poo, viz. from Weft to Eaft, which is contrary to the general Motion. And 270 'fl^e Abfilute Fart Sect. IV. And fuch is the Force of this Current, that when Ships approach too near the Shore it carries them violently toward that Bay, and deceives the Ma- riners in their Reckoning. Hence it comes to pals, that Ships which lail in two Days Time from the Shore of Mouree to Rio de Benin^ [or For?nofa'] which is one hundred Dutch Miles, re- quire fometimes fix or feven Weeks to return from Benin to Mouree^ unlefs they run out into the main Ocean, which is not eafily done, be- caufe the Current fees to the North-Eaft, and runs fwiftly from the Ifland of St Thomas^ towards tiie Bay of Fernando Poo, carrying in with it the Ships tho' they have a fair North-Eaft Wind ; and they can fcarcely get from the Shore, unlefs they be driven by thefe fudden Storms which break from the Clouds (called Travados^ which feldom happen, and in fome Months not at all. This Current dcftroyed feveral Ships before Mariners were well aware of it ; as being either unadvifedly driven upon the Rocks and Shoals, and periflied by Shipwreck, or detained in the Bay 'till they died with Hunger. BUT this Current affefts not the whole Etbio- pc Ocean, only that part which is adjacent to the Shore of Guinea, to the end of the Bay, and to about one Degree of South Latitude. It is obferved not to exceed the Diftance of fourteen Miles from the Shore ; therefore Ships are very careful left they fhould approach fo near, when they fail along thefe Coafts ; which would hinder their intended Courfe, and drive them to a Place they would not care to vifir. IT is no eafy thing to find out the Caufe of this Current fo near the Shore, when the main Ocean thereabouts moves the contrary Way from Eaft to Weft. Two Things may be faid for it : . , . I. THE C H A p. 1 4« tf Univerfal Geography. 271 1. THE Ocean being repulfed by the Ame- rican Shore moves flowly to the Eaftward, but this Motion is not felt in the Main, becaufe the other deftroys it, and renders it lefs fenfible, only near the Shore it runs fwiftly towards Fernando Poo, which, being ftretched a pretty way into the Land is fitted to receive it ; and the Reafon why it is not felt in other Places upon the Shore of A- frica (as at Congo) is, becaufe the Rapidity of the Rivers breaks and ob(lru6ls it. 2. THERE may be fome fubterraneous Re- ceptacle in the Bay oi Fernando Poo, into which the Sea perhaps may fall and draw the reft of the Ocean. But this may feem lefs probable ; they that have opportunity of obferving it better may give better Rcafons. PROPOSITION XXIV. \To point out the Place of the fecond perpetual Currentl» THE Ocean moves fwiftly from about Stima^ tra into the Bay of Bengal, from South to North ; fo that it is probable this Bay was made by the Rapidity of the Current ; by which alfo perhaps the Peninfula of Malacca was feparated from India. I do not know whether the Caufe may be owing to the many Iflands, and to Cape Mabo, upon the South Continent, whereby the Ocean in it's Paffige weftward may be diverted northwards : or there may be a fubterraneous Receptacle in the Bay it- felf. B E it how it will, I fuppofe the Current doth not fet diredly to the North, but rather to the North-Weft. This fame Current is felt between Java and the South Continent, and therefore when the IDutch fail to the Indies^ they iirft make to- wards 272 ^^^ Ahfolute Part Sect.

For in the main Ocean, remote from the Shores, this Motion is not oblique but diredt, from Eaft to Weft. PROPOSITION XXVI. [To point out the Place of the fourth perpetual Current], I N the Pacific Ocean, along the Shores of Peru^ and the reft of America, the Sea flows from South to North i which, no doubt, is owing to the con- ftant South Winds which blow upon thefe Coafts ; for neither thefe Winds, nor the Currents are ob- ferved out at Sea.

THIS is obferved to flow from Cape St Au- guftin^ in BrafU, along the Coaft of America, a~ moi g the Antilles in the Bay of Mexico, towards Florida, which is from South to North. For the Sea being driven by it's general Morion againft the Shore of Brafil, is there repullcd, and car- ried northward, where the Clianel is broader and more open, which very ]ikely caufes this Cur- rent.

It is not much amifs fliiys he.) to fuppofe the Water, received into the Caverns, in the Cliffs of the Rocks below, iffueth from thence ; for by the continual running in of the Water the little rocky Bays are filled, and being full, they emit what they received, thro' winding and fubterraneous PalTages ; whofe Capacity is fuch, that they pour out the Water for lb many Hours, whereby the Tides are now obftrufted or repelled, and a little after forwarded or helped. But any one may per- ceive the infufficiency of this Caufe. THE Maeljlroom on the Coaft of Norway, is the fwifteft and largeft known Vortex ; for it is fa id to be thirteen Dutch Miles in Circuit; in the mid- dle of which there is a Rock, which the People thereabouts call the Moujke. This Whirlpool, for fix Hours, fucks in whatever approaches it, or comes nigh it ; not only Water, but Whales, load- ed Ships, and other Things •, and in as many Hours difgorges them all again, with a hideous Noife, (0) There are on each fide the Euripus is regular, and ten the Euripus fix or feven in which it is irregular, «-y/z. five Gulphs, wherein the Water Days before and after the New fliuts itfelf up to illue from and Full Moon, in which there thence as often as it enters there; are nine or ten Changes of the and the Situation of thefe Courfeof theWaterevery Day : Gulphs perhaps contributes to and in each of thefe Changes the this fudden Flux and Reflux, of Water flows about a Foot, and which the Moon feems to be ebbs back again.

Of the two lall fome are always full of Water ; others are dried up in Summer, and when it is conllanily lair Weather -, both thefe Sorts are called Ponds. As to thofe that are dried up, it is eafy to fhew their Origi», inz. abundance of Rain, which gathers and Itag- nates in fome Cavity, or depreffed Place. For if any Pit be fituated in the middle of a defcending Ground, the Rain- Water every way drains thither, and makes a Pond. THERE are feveral fuch Ponds as thefe in India^ made by the Induftry of the Natives, of which fome are a Mile, and fome two in Circuit •, they are furrounded with a ftone-Wall. and are filled in the rainy Months, to fupply the Inhabi- tants, in the dry Seafons, who live a great Way from Springs or Rivers.

By this means in Mufcovy, Finland^ and Laplandy in the Spring, Summer, and Autumn, they have many Jit[le jLakes, which are generated partly by the Rains, and partly by the melting of the Ice and Snow. BUT tho' fome of thefe Ponds may happen to be dried up in Summer, or when it hath not rained for a long Time ; yet we are not thence to conclude, that they are wholly fupplied with Rain-Water •, for they may be dried up, tho' there are Sources, or Springs, in the Bottom, which perhaps, are fo little that the Heat of the Sun, in Summer, dif- fipates the Water, and turns it into Vapour. AS to thofe that admit no Rivers, and yet are not dried up, they may wholly proceed from Rain if their Chanels are deep and capacious, and in which fo much Rain-Water may be contained, that the Heat of the Sun cannot confume the whole before more Rain fall to replenifh them ; tho* it is very likely, that many of thefe are fupplied by Sources under Ground, which continually e- mit as much Water as is exhaled ; efpecially thofe Takes that are found upon the Summits of Moun- tains, 3.S u\')on Bru Merits, Cenis, Sec. Some of them have perhaps been left, at firft, by an Inunda- tion, and are continually fupplied and kept up by Rain-Water : And we need not doubt but that thofe Salt- Water Takes, or Ponds, that are lound near the Sea, were made at firfl by the In- undation, or ImmilTion, of the Sea- Water, fome way or other ; as the Take of Harlej?i, and others in Holland.

Some little ones are obferved in Mufcovy and Finland^ the Lake Locafda m yEpirus^'] the Lake Bufaranda, in /Imajia-, one in Larnwlay called the Ztrchnitzer Sea •, a round one in China ; another called Hila in Ccchin-China ; one in 'Zan- haga in Africa ; two in Mexico^ in America^ the one of them leven Leagues long, and the pther near as big. All thefe are but Imall ones, except that in China, which is of a moderate Bignefs, BUT the only one great Lake in the whole Earth of this fort is the Lake Parime in America, lying diredly under the Equator. It is in length from Eaft to Weft, about three hundred and jpve German Miles, and, in the broadeft Place, one hundred Miles over, or thereabouts •, fo that it may be compared with, ii it do not exceed, any Lake in the World for magnitude ; yet it neither receives, nor emits any Rivers. It may reafonably be doubted how this Lake was produced, whether by fome former Inundation of the Ocean, or by fubterraneous Springs and Sources ? And whether it is fed and kept up by Rain-Water, or the like ? It feems probable that there are Springs in the Bottom which fupply it with as much Water as is daily evaporated by the Heat of the Sun. For Lakes feem to have the fame Origin as Rivers, only they differ in the Situation of their Springs, and the quantity of their fpringing Water. Eor if a Spring be furrounded with rifing Ground, and run into a deep and broad Chanel, and alfo fend forth but a fmall quantity of Water, it doth not run, but is evaporated as faft as it fprings. There is no Difference therefore, in the main, between Springs, Lakes, and Rivers, only in fome Circum- Itances \ and there are found feveral Springs which do not emit Water ; but fuch are more properly called Wells.

For when Rivers in their Courfe meet with a broad Plat of low Ground, they are there coUeded, and form a Lake -, which (if the Soil be light, and porous to tranfmit the Water to the ad- jacent Fields, or if there be a fubterraneous Re- ceptacle, or, which is mofb likely, if the Water work it's way under Ground) never overflows but lofes, infenfibly, one way or another, as much Water as it receives. X'il ERE 286 l^je Ahfihite Tart Sect. IV. T HERE are not many of thefe Lakes taken Notice of. 1. IN the foregoing Propofition we obferved that the Lake \Tiiicaca\ difcharges a River into a fmaller called Paria, which therefore may be re- ferred to this Clafs, viz. to fuch as receive Rivers but emit none. 2. THE Lake Jfpballiies, which is alfo called the Dead Sea, receives the River Jordan, but e- mits none.

PROPOSITION VL To explain the Origin of thofe Lakes that both receive and emit Rivers. THEY are of three kinds, as was faid be- fore in Propofition 2, and either emit more Water than they receive, or an equal quantity, or lefs. If they emit more, it is evident they have fome hidden Springs in the Bottom : If Itifs, the Earth is either fpongy, or there are fubterraneous Aque- ducts, whereby the Water is conveyed under Ground: If an equal quantity, it is a Sign that there are neither Springs nor Swallows at the Bjt- ....»* torn. Chap. 15. of Univerfal Geography. 287 torn. Their Origins therefore arc partly explained in Propolition 4, that is, are owing to a low Ground where there happens to be Springs, and into which Plenty of Rain- Water is drained. SUCH as are generated by the Influx of one River, and afford a Faffage lor it in at one Side, and out at another, are found in many Places. Thus the Niger makes three Lakes in it's Courle, and runs upon the Side ot another. The Nile makes feveral more Lakes than are Ihewed in our com- mon Maps. The River Duina at leads runs thro' fix, or feven. Lakes. And there are fome Rivers in Mufcovy and Finland^ that make, as may be feen in our large Maps, at leaft fixteen Lakes be- fore they exonerate themfelves into the Sea. We fhall only here enumerate fuch as produce other Rivers than thofe they receive. I. THE Zaire^ a Lake, or Morafs, in the Foreland of Africa^ lies between the fecond and ninth Degree of South Latitude, and therefore is about one hundred and five German Miles long. In the middle of it there is an Ifland ('befides feve- ral fmall ones) fo large and populous, that the Inhabitants can raife an Army of Thirty thoufand Men. This Ifland almofl divides the Lake into two Parts, which have each a peculiar Name; that to the fouthward is called Zamhre.

T H E Lake Zachaf^ not far from Zaire^ to- wards the Cape of Good- Hope ^ emits a River, which being joined to others, is called St Efprit, or Delagoa. 4.

It receives feveral conliderable Ri- vers from other fmall Lakes, and difcharges one, called the Sueri., into the Lake Ladoga. 6. THE Lake Ladoga is about thirty German Miles long, and fifteen broad ; it receives the River Sueri., out of the Lake Oz/t'^^^, and other lefler ones from other Places •, alfo a confiderable one from the famous Lake Ihnen in Mufcovy. It difcharges one River into the Gulph of Finland. 7. [THE White LakeJ or Ozero., receives fome fmall Rivers, and difcharges the River Shackfna which falls into the IVolga. 8.

It feems to me to have no Communication any way with the Ocean, and therefore ought rather to be called a Lake, than a Sea. How it came at firft is another Queftion. Some avouch that there are found feveral Moun- tains of Salt in the Bottom, whereby it hath ac- quired fuch a Degree of Saknefs j and that it is re- plenilhed by the many Rivers that exonerate them- felves into it. But it feems more teafible, (i;-vV thefe Rivers may contribute to it's Repletion) that this Sea hath, a great many Ages ago, been joined to the Ocean, and that it's Streights, by fome means or other, were filled up and flopped, per- haps by interjacent Iflands which gained upon the Shores, in a manner which we (hall explain here- after.

This PropofitioJt contains fotne necejjar^ 'Dejinitions. I, A RIVER is a Flux of Water continued x\_ thro* a long narrow Chanel, from one part of the Earth to another. The Chanel is a Cavity, or hollow Place, made lower than the Banks, for the Water to run in. 2. A Brook is a little River, which is neither broad nor deep enough to carry a fmall Ship of Burden. A Navigable River is capable of carrying all forts of Ships, great and fmall ; but thefe and the other fort are generally called great and fmall Rivers, according as they are in bignefs. A Tor- rent is a violent Flux of Water trom the top of a Mountain. 3. A Confluence, Concurrence^ or Conflux, is a Place where two Rivers meet. 4. B RANCHES of Rivers are the Brooks that run into them, and mix with them -, or when a River is divided and runs in two Chanels, they are called it's Arms or Branches. Where the River is thus divided, it is called the Place of Parting or Divarication, 296 ^he Abfolute Part Sect. IV. 5. A Spring is the Place where running Water fprings out of the Ground. A IVdl is where the "Water rifcs and runs not forward, but is kept upon the Spot. / P RO P S II'IO N II. Torrents and Brooks are fometimes generated from Plenty of Rain and melted Snow. I N the elevated or mountainous Parts of the Earth, there, are lound many Receptacles, fmall Lakes, and Pond^s. And when the Rain is poured into thcfe, or the ir.elted Snow, in fuch Quantity, that they are not large enough to contain it, they overflow and difcharge the luperPiuous Water into the under-land Places. This being done every Year, the Water in time makes icfelf a Chanel (tho' it fometimes flows without any certain Cha- nel). Thus a great many Torrents and Brooks, being fed only by Rain, or Snow melted from off the Mountains, before they have run their Courfe, become moderate Rivers ; efpecially if they pro- ceed from a long Range of Mountains ; as thofe in the Foreland of /Ifrica^ India^ Peru, Sumatra, i^c. And what is remarkable, fuch Torrents flow in the Day-time only. PR PO S iriON III. Mojl Rivers have their Rife from Springs. THE great as well as the middle fized Rivers, proceed either from a Confluence or Collection of Brooks and Rivulets, or flow from Lakes and Mo- raflTcs. But no River of confiderable Magnitude (fuch as the Elbe, tht Rhine, &c.) flows from one Spring or one Lake, but is augmented by the ac- cefllon Chap. i6. of Unherfal Geography, 297 ceffion of others, flowing from other Fountains and Lakes. The IVolga or Rha receives above two hundred Rivers and Brooks, before it exonerates itfelf into the Cajpian Sea •, and the Danube receives no lefs, before it enters the Euxine Sea. AND tho' Plin'^ and Cardan tell us, that no Rivers flow into the Kile^ yet Experience fhews the contrary -, as they that have travelled into Ah)ffinia allure us. THIS Propofition may be proved by innume- rable Examples. THE Springs of Rivers are fome of them found on the tops of Mountains, and fome on the Planes *, and thofe Rivers that proceed from Lakes, have their Fountains (as was faid in the laft Chapterj at the bottom, or in the Chanel, of tiiofe Lakes that produce them, which like Ciilerns contain the effu- fion of Water, 'till in a greater Quantity it be poured into it*s proper Chanel. Hence fome F'oun- tains are covered with Earth or Water, and others lire open. THE Springs of the Rivulets which begin the Tan'ias and the Elhe^ are on Planes, to which others are afterwards joined. We might here add feveral Examples, but thefe are fufficient. C ARDAN is of Opinion, that thefe Fountains do not flow immediately from the Plane itfelf, but are conveyed by fubterraneous Aquedu6ls from the adjacent Mountains ; however, 1 believe they tirlt make a Lake or a Morafs -, for the Tanais docs not feem to flow immediately from a Spring, but from a Morafs or fhallow Lake. THE Springs of moft Rivers are upon Moun- tains, as thofe of the Rbine^ the Po, the Danube^ the Niger, ^c. SEVERAL flow from Lakes, as the Nile^ the IVolga, and the great River of Si Lawrence in Canada. A great 298 "The Ahfihte Tart Sect. IV. A great R.iver may happen to flow from one Spring, if the Spring icfelf be fuuated high (as moft arej and a great part of the Chanel low, or but a little higher than it's mouth •, fo that the Water flowing with a fwifc Courfe at firft, and by degrees flower, is increafed in the Chanel and becomes a large River, becaufe it difcharges not fo much Wa- ter at it's mouth, as it received from it's Spring when it iirfl began to flow. p Ropos irio N IV. Rivers are fnuch augmented by frequent Rains or incited Snow, and at particular Times oj the Tear. I N the Country of Peru and Chili there are forrtft Rivers fo fmall, that they do not flow in the Night- time, but only in the Day ; becaufe they are fed by the Snow upon the Mountains of the Andes, which is then melted by the Heat of the Sun. There are alfo feveral Rivers upon both fides of the extream Parts of Africa, as in Congo, Angola, &c. which are greater by Day than by Night. The like are found both in Malabar and Cormandel in India. The Rivers alfo in thefe Places are almoft dried up in Summer, but fwell and overflow their Banks in Winter, or the wet Seafons. Thus the IVolga in M^v and June is filled with Water, and o- verflows it's Shelves and Iflands ; which at any other time of the Year is fo fliallow, that it fcarcely af- fords a Paflage for loaded Ships. For the Snows being melted at this time of the Year, on the Mountains, from whence the Rivulets (being more than an hundred^ flow into the Wolyi, caufe this Inundation. The Kile, the Ganges, the Indus, (s^c. are fo much fwelled with Rain, or melted Snow, that, In like manner, they overflow their Banks. But thefe Deluges happen at divers times of the Year, Chap, i 6. of Unherfal Geography. 299 Year, becaufe they proceed from various Caulls and difFerenc Places.

Moreover fome Rivers, efpecially the large ones, flow from Places at a great Dillance, where it is Summer at the fame time it is Winter in the Places where they pafs through •, and for this Caufe they overflow their Banks at different times of the Year. But moft of them caufe an Inundation in the Spring, becaufe the Snow is then melted in mofl: Places.

W E (hall alfo in the next Chapter treat of that remarkable Spring in Ja^an, which only flows for two Hours every Day. PRO PO S iriON V.

The \'apours meeting with thele Ridges of Mountains are there compelled by the Stream of the Air to mount up with it to their Tops, where meeting with more rarified Air, they naturally fall down in Drops, pervading the Crannies and Fifiures of the Karth, and glecting into the Ca- verns of the Hills, the Water thereof gathers into the Bafons of .Stone,orClav, it finds, which being once filled, all the over- plus of Water runs over, and, where it can find a Pafiage, breaks out at the Sides of the Hills, and forms Fountains ; many of thefe, running down the Vallies, or Guts, between the Ridges of the Flills, and coming to unite, from Rivulets or Brooks ; niany of thefe again being united into one common Chanel, form vafl: large Rivers, as the Rhine, or the Danube. This Theory of the Caufe of Springs the fame excellent Per- ion proves by Experience. For he fays, that when he was in the Ifland of 5/ Helena, taking Aftronomical Obfervations in the Night-Time, on the Top of the Hillsabout 800 Yards above the Sea, he found fuch a Con- denfation of the Vapours, that in 7 or 8 Min. Time, tho' there was a clear Sky, the Glafles of the Telefcopes he ufed were co- vered with little Drops, and the Paper on which he wrote his Obfervations would immedi- ately be fo wet with the Dew that it would not bear Ink. This Hypothefis he thinks more reafonable than that of thofe who derive all Springs from the Rain-Waters, which. yet are perpe'^ual and without Diminution, even when no Rain falls for a long Space of Time : Or than that which de- rives them from a Filtration or Percolation of the Sea Waters, thro' certain imaginary Tubes or Pafiiiges within the Earth, wherein they lofe their Saltnefs. This Opinion labours under this principal Abfurdity, that the greatelt Rivers have their moll copious Fountains farthell from the Sea, and where fo great quantities of freili Water cannot reafonably be derived any other way than in \ apour. See Philof. Tranj: N^ 192. Pag. 468. Notwithltanding it is very probable that all Fountains have not the fame Origin ; but that fome proceed from Rain penetra- ting the Fiffures of the Earth, and flowly gleeting thro' the Inter- ftices to the Orifices of Springs i and others, efpecially thofe that are fait, and placed near the Sea Shore, take their Rife from the Sea C H A p. 1 6. of Uni^erfal Geography. 301 becaufe of the Quantity of their Water, than when we look upon fmall Brooks. But we have fhewcd in tlie two laft Propofitions, that Rivers proceed partly from Rain and melted Snow, and partly trom Lakes and Concurrences of Brooks and Rivu- lets ; and therefore we do not enquire lb much here about the Sources of Rivers, as about the Origin and Permanency of Springs. THE Opinions of Naturalifts and Geographers are various about this Matter. I. SOME think that all Rivers and Springs re- ceive their Water from Rain, or melted Snow ; and this they bring for a Reafon, that Rain and melted Snow fometimes augment Rivers to fuch a degree, that they overflow their Banks, and lay whole Countries under Water : But in the Summer Sea- fon, when no Rain has fallen for a long Time, Sea Water percolating thro' the Sands ; but the greatei: pare of Fountains, efpecially fuch as break from the fides of high Hills, derive their Waters from Vapours, as was faid above. The learned Dr/'/'jort'iu^rrt', in his Natural Hijlory of the Earth, explains the Origin of Fountains otherwife. He imagines, that there is a great Abyfs,orPromp- tuary, of Waters, inclofedinthe Bowels of the Earth, which, com- municating with that of the Ocean, is continually exhaled into Vapours, by the Force of a fubterraneous Heat which he proves by many Arguments to be in the interior Parts of the Earth ; and that as thefe make their way upwards, they pervade the Fiifures, and Intervals of the Strata of the Earth, per- meating alio the very Interftices of the particles of fand, earth and Stone, 'till they come near the Superficies of the Earth, where they are condcnfcd with cold, and come together by Drops, which, being collected, break out at fome Aperture or other, and form Fountains. But when the Heat above the Superlkies of the Earth, is as intenfe as that in the interior Parts thereof, it takes the rifing\''apour, where it penetrates the Superficies of the Earth, and bears it up into the Air, or at leail diminifhcs greatly. They who would fee thisHy- pothefibiiiore accurately explain- ed, let them confult the learned AuthorinhisBook: Itisenough for us only to mention it, ac- counting Dr Halltys Theory much more clear, and built up- on a better Foundation. Jurifis .appendix. the 30 2 l^je Ahjoliite Tart Sect. IV. the great Rivers grow lefs, and the fmall ones arc moltly dried up, becaufe the Chanels of the later are too fhallow to contain any large quantity of Water ; but the former, whole Chanels are deep, do not ceafe running, nor are dried up, becaufe they have collected fo much Water from the for- mer Rain and melted Snow, that it cannot all be exhaled into Vapours, except it be by a lafting and conftant Heat. 2. Becaule there are the teweft. Rivers where it feldom raineth, as in the inland Parts of Africa there are but few Springs. BUT thefe Allegations do not folve the Pro- pofition, which doth not enquire about the Ori- gin of Rivers, but from whence the Water of Springs proceeds ; therefore they that take this to be a Solution do not underftand the Senfe of the Proportion, as we obferved before. And even the Property they propofe to prove it by is not uni- verfal ; for there are Rivers found in Places where they have feldom any Rain and no Snow, tho* what they fay is true concerning the Rivers in £- g^pt and Peru. Befide, Rain- Water doth not pe- netrate into the Ground beyond the depth of ten Foot i whereas feveral Fountains fpring from a greater Depth. 2. OTHERS think, that we are not to en- quire about the Origin of the Water of Springs, fince it is an Element as well as the Earth, Air, and Fire, whofe Origins are not enquired into. This is Seneca's way of arguing. But thefe Authors cut the Gordian-knot when they cannot untie it ; for we do not difpute about the Principles of Water, but en- quire how it flows to the Heads of Rivers, rather than to any other Place. Moreover, the Earth is not a Fluid as Water is •, and to fay, that the Air and Fire are not enquired into, is falfe. 3. THE Peripatetics follow the Opinion of their Mafter AnJlotUy delivered in Chapter xi. 3 Book Chap. i6. of Unherfal Geography. 303 Book i. de Meteor, where he endeavours to prove, that the Water of Springs is generated from Air contained in the Bowels ot the Earth. Thefe are his Reafons ; i. The Air, furrounding the Earth, is turned into Water, viz. into Rain •, and tlierefore fince there is alfo Air in the Bowels of the Earth, and the fame Caufe to condenfe it, viz. Cold, it is contrary to Reafon to think that Water is not produced from Air there. 2. Experience teaches us, that great Drops gather from fmall ones under Ground, and therefore the Heads of Rivers are only a great many Springs gathered into one Place. For this Reafon, they that make Aqueduds, ufe to draw the Water thro' narrow Trenches and Pipes, which diftils, as it were, from the moift Earth, Drop by Drop. 3. Becaufe moft Foun- tains, efpecially of great Rivers, are found on mountainous Places, and but few upon Planes, it is a Sign that their Water proceeds from conden- fed Air or Vapours, which naturally tend towards high Places ; and Mountains are Sponges, as it were, lying upon the Planes. Thefe are Arijlotk^s Reafons, to which this following may be added of no lefs Force than the reft, viz. that when the Air is clouded and filled with Vapours, acid Fountains tafte fweeter, which is a Sign they are augmented by the Air. 4. C A RD y^ A^and others are of Opinion, that the Water of Fountains proceeds from little Drains or Guts collecting the condenfed watery Vapours both above and under Ground ; but thefe feldcm become Rivers, without being increafed with Rain and melted Snov/. His Reafons are tliefc ; i. If you obferve the Mountains in the Morning you will find them full of Moifture. 2. Rivers in the Morn- ing are found to fwell, and the more the nearer they are to their Springs. BUT 3 04 The Ahfolute Part S e c t. I V. BUT the perpetual bubbling and fpringing up of the Water from Fountains, without any inter- mifTion, does not feem to be produced by {o weak and inconftant a Caulc. Neither is there much Difference between Anjlotle^s Opinion and this of Cardan •, only Arijlotle fiys, Fountains proceed from Air condenfed, and Cardan, from Vapours ; and there is but little Difference between Air and Vapours. 5. SOME of the Antients were of Opinion, that Rain- Water is hoarded up in the internal Ca- verns of the Earth, from whence it iffues, as out of a great Promptuary, and that all Rivers are fupplied from one common Fund, or fpring one from another ; alfo that no Water is difperfed over the Earth but fuch as is colleded in the Winter Seafon, and referved in thefe Receptacles, to be poured in due Time into innumerable Rivers. For this Caufe, fay they, Rivers are greater in Winter than in Summer ; and fome are perennial, others not. Their Reafons are the fame with thofe given for the firft Hypothefis. But Arijlotle and his Followers rejedl this Opinion, becaufe there is more Water poured out of the Mouth of one Ri- ver in a Year, than the whole Bulk of the terra- queous Globe. 6. M A N Y of the modern Philofophers, with the Antients, fuppofe the Earth to fuck in as much Water as it exonerates into the Sea, thro' the Mouths of Rivers i and that the Sea Water, by draining thro' the hidden Receffes of the Earth, and by being drained thro' the Mazes and Fiffures, and thro' the Interftices of the Sand and Grave), lofeth it's Saltnefs, and becomes pure Water. I am alfo of this Opinion, and think it mod reafonable, but do not exclude the Caufes repea- ted in the firft and third Place. The Reafons for ic are : / I. BECAUSE Chap. i6. of Univerfal Geography. 305 1. BECAUSE more than a thoufand Rivers exonerate themfelves into t\\Q Sea, and the larger fort produce fuch quantities of Water, that what each of them pours in a Year's Time into the Sea, exceeds the Bulk ot the whole Earth i as what the JVolga pours into the Cafpian Sea, and others. So that it is impoffible but that t!ie Water fhould b^ refunded out of the Sea into the Earth, and carried to the Heads of Rivers ; elfe we could not conceive why the Sea is not increafed to an immenfe Bulk, or why Springs do not ceafe to emit Water. Nei- ther can any one obje6t that there is as much Wa- ter exhaled from the Sea in Vapours, as it receives from the Rivers •, for Rain alone returns thefe Vapours, and if the Water of Rivers were con- tinually turned into Vapours, it would produce more than thofe exhaled from the Sea. 2. THIS Opinion is alfo thus proved, becaufe that Springs near the Ocean are falc or brackifh, and the nearer they are the Sea, the more they are fated with Salt i as on the Shore of Jfrica^ and in India^ chiefly on the Shore of Cormandd^ where no Vines grow, and all their Wells tafte fait. Near the Town of Sue^,^ at the end of the Red Sea^ their Springs are all fait and bitter j and even the Water which is fetched two German Miles from the Shore, taftes a little brackifh. Alfo in feveral fmall Iflands there are no frefh Water Springs, but all fait ftho* fomething lefs fated than the Ocean^ as in the Ifland of St Vincent^ and others. In the low Countries of Peru ^ that border upon the Ocean, their Lakes are falteft, becaufe of the Vicinity of the Sea. And in the maritime Parts of feme ealiern Countries their Cocoa-nuts are obferved to tafte brackifli. Not to mention the Salt Springs that are found in inland Countries, as in Lorrain^ Lunen*. burg^ i^c. VOL. L X 3. BECAUSE 3o6 The Abfolufe Part Sect. IV. 3. BECAUSE it is certain, that the Sea fends ii's Water thro' iubterraneous Conduits to the lalc Springs of Lumnburg, Hall^ &:c. whofe Feeders are obfeived to contain perfect Sea- Water under Ground. , 4. B EC A USE if we dig to a great Depth, as is oiten done in Miiies, we lliall find plenty ot Water, which can neitlier proceed from Rain nor Air. BUT by what means the W^ater is carried from the Sea to the Fountain-Heads, and how, in the PalTage, it becomes fweet, we have already explained ; and fhewed that the Bottom of the Sea not being in every Place rocky, but here and there fandy, gravelly, and oozy, imbibes the Sea- Water, and letteth it into the Earth ('after the fame manner as when we throw Water upon Sand, Beans, Peas, Wheat, or other forts of Grain j thro* whofe Interfticcs it is brought by degrees to a great Diftance from the Sea, where at length the Imall Drops come together, efpecially in Itreight Places, as are Mountains, (^c. and having found an Aquedudl they difcharge themfelves at a Spring. But if the Cavity, where they are colle<5led, be covered and bound up with the Earth, then tlie W^ater will take another Courfe, where it can with greater Eafe infmuate itfelf, and fpring up at an Aperture in another Place •, which is not the real Fountain, but a Conveyance of the fubterraneous R iver to a Place above Ground. And if the Water can find no Way out of the Receptacle, and hath not force enough to make itfelf one, it is not jncreafed, but the fubfequent Particles of Water are turned another Way. For it is the nature of all Liquids and Fluids, that their Parts or Par- ticles flow towards that Place where the Flux is made. Thus if you fill a Veflel with Water 'rill it rife above the Brim, tho* all the raifed Parts of Chap. i6. of Univerfal Geography. 307 of the Water equally prels the Brim, and have an equal Tendency and Power to run over at the next Side, yet if on one Side of the Vcficl any part of the incumbent Water be made to flow, the reft will forfake their refpedive Sides, and move (as if they were drawnj towards that Side where the Flux is begun fthe Caufe of which it belongs to Ph'^fics to explainj (b). Or if you put one end of a Piece of Bread into Water or Wine, you will fee the Water move upwards and diffufe itfelf thro* the Part above Water. Moreover the Sea eafily pervades the Fifllires of the Earth, and therefore with the fame eafe may glide out of them ; except we had rather afcribe this to Evaporation, where- by the Particles are carried upwards, and con- denfed into Drops, v;hen they meet with narrow Places. BUT becaufe there are fome Arguments, which may feem to render this Opinion lefs probable, we will difcufs them here, left they Ihould feem lil^e Blots upon our Hypothefis. 1 . S P R I N G- Heads are more elevated than the Superficies of the Sea, and for the moft part arc feated in mountainous Places •, therefore it is con- trary to the Nature of Water to move from the Sea up to thefe Places ; for Water always runs downwards, as is manifeft from Rivers and Drains. 2. THO' the Bottom of the Sea be fandy, gravelly, and fpongy, fo that the Water may eafi- ly pervade the Interftices ; yet for what Reafon Ihould it not rather moiften the fnbjacen: Parts of the Earth, than afcend upwards, and glide to the Duds of Fountains, when the Earth near the Sur- (h) We gather from S\r Ifaac the Parts of one another; Thus Ne-iJutons Principles, that it is Water attratSteth Water, and the Nature of Fluids (and of ail the Particles that firft begin to the Matter in the Univcrfe] mu- flow, drrAVthe next Particles to tually toattra6tthemfelves, and them, and thefe the next, ^c.

And we are as much in the dark, why there is none or very little Water found in deep Mines, as we are told by Thurnheuferus, • 4. SPRING fFaie/muit be fait, if it proceed from the Sea. THESE are the chief Arguments which feem to invalidate our propoled Hypothefisj for I pafs by thofe of iefs moment alledged by others, as that the Sea cannot fupply fo many Rivers : and then again, that Rivers would never leflen, if they proceed from whence we lay they do. Thefe two are foon anfwered •, for firft, the Sea receives the Water it emits into Fountains, from the Rivers ; and the other, as we obferved before, is not the Quellion, for we are not arguing, that all the Wa- ter of Rivers proceeds from the Sea, but only the Water of Fountains, which of themfelves make Rivers, as we faid before ; where we alfo afTened, that Fountains are augmented by Rain and Dew, which fink down into the Earth and either foke and moiften it, or are drawn towards the Fountain- heads by the EfBux of the Water, as we fliewcd by other Examples. Let us therefore return to ex- amine the other four Arguments which feem to be of fome Weight. THE firft is thought to be the ftrongeft, as being taken from Experience, and therefore the Learned have contrived feveral Anfwers to it. They come offeafieft who aflert that the Ocean is higher than the Earth, and confequently higher than the Fountain-htatls ; wherefore fay they. Water naturally flows to the Fountains, becaufe they are of a kfs Altitude dian the Ocean. Olea- rius Chap. i6. oJU?iiverfal Geography. 309 rius alfo in his Defcription of his Travels into Per- fia relates, that having arcended one of the Moun- tains which bordereth upon the Cajpian Sea, he tried the Altitude of it above the Superficies of that Sea with an Aftrolabe (or rather a Surveying Inftrumcnt) and found none ; but oblerved, that the extreain parts of the Sea feemed to be in the fame horizontal JLine, or even a little elevated above it ; and there- fore the bulging of the Sea made it as high, or even a little higher, than the top of the Moun- tain, where he took the Obfervaiion. But this So- lution notwithflanding cannot be admitted, becaufe we proved in Chap, xiii, that the Superficies of the Ocean is not higher than the Land, or than Moun- tains, but rather lower, as appears alfo from fre- quent Obfervations made by expert Mathemati- cians. As to Oleariui\ Obfcrvation, it is not to be infifted upon here •, for the Cafpian Sea is not higher than it's Shores, much lefs than the Mountains,- as appears from the many Rivers that exonerate them- felves into it. We muft therefore fuppofe, that Refraftion obftruded Oleariui^s Obfcrvation, and made the Surface of the Sea appear higher than it really is ; and perhaps the flu(ftuating of the Waves might increafe the Caufe, or the Mountain which he afcended was of no great Height. - - THE Weaknefs therefore of this Solution being expofed, others propofe this ; that the natural Place of the Waters is about the Earth, and therefore they ought to furround or cover it, becaufe they are lighter ; and becaufe they are hindered from pof- fefllng their natural Place by the Mountains and Hills, and the Elevation of the inland Places, that part of the Ocean which fhould be where the Moun- tains and high Parts are, being thruft out of it's natural Place, violently pre fifes the Water under- neath it, which tho' it be in it's natural Pofture, yet being fqueezed and prefifed towards the bottom, X3 by 3 I o . ' The Abjolute Fart S e c t. I V . by the fuperincumbenc Water, it is forced to give way, ana tindirig no place to flow to, it retires to- wards, the Sides, and pervades the P'ouncations of th€ Mountains \ where being colleded, as in a Ci- flern, it is. Itill urged forwards towards the tops of the Mountains by the incumbent Water of the O- cean. As we may obferve in a Tankard that has a Pipe on the fide (reaching to the very bottom) made to pour Wine thro' into Glafies j if, I fay, we drop a Stpne into fuch a Veflel, whether it be full or half full of Liquors it will fpout out at the Orifice of the Pipe. 1 his is Scaliger's Subtility, but it is too grofs to pafs. For the Water is not thus forced towards the tops of the Mountains, fince Experience fhews us the contrary in Mines ; and if it were fo, the Water of all Springs would be fait ; befides, it is falfe to fay that the Water is not in it's natural Place, and therefore prefles upon the Water underneath, for this is allumed without Proof, and is contrary to Experience. Water does not prefs upon the Parts below, unlefs it's Surface be of an unequal Altitude, but the Surface of the Ocean is fpherical and confequently at Reft. More- over, if the Waters were moved by any Preflure, it would be towards the Shores, where the PafTage is more open than the fmall Fiflures of the Earth. And tho' there be great oudets at the bottom of the Sea, for the Water to f^ow through, yet fince it is fait, it cannot make frefli- water Fountains. I think the true Anfwer to this Argument is not far to fttchy if, we confider how Water is conveyed to Fountains, not by any Chanel or Pipe from the bot- tom of the Sea, or the Root of the Mountain Cby which means it would ftill keep it's Saltnefsj, but by a continual diftilling, gleeting, and draining of the watery Particles thro' the terreftrial Matter, till they find a Receptacle fit to colled and condenfe them ^nro Drops, where being continually fucceeded by A others. C H AP. i6. of Vniverfal Geography. 3 1 1 others, they have recourie to fome Conveyance, and through it break forth at a Fountain. And wc. obferve this very thing in Mines dug to a vaft Depth, how that Water on every Side is continu* ally dropping, and colledling itfelf into imall Guts, which they call Veins of Water j and if feveral luch Guts or Runnels as thefe concur in one Re- ceptacle, they form a Fountain, as they who make Drains, to bring Water into Wells, very well know. For in moft Draw- Wells the Water is col- Jeded from the dropping of the Earth, round about into the bottom of the Well -, and they that make Aquedudls dig fmall Furrows in Gutters to colled the Waters, and then convey it in a large one to the intended Place. If it be objcded, that many Fountains are obferved to fpring up a- mong Rocks, where it is likely the watery Par- ticles can fcarce be admitted j I anfwer, That this confirms our Opinion ; for thefe Rocks are not continued to the foot of the Mountain (upon which - fuch Springs are found) but only cover the Sur- face to a fmall Depth, and the Earth is lighter and lefs rocky within, or at lead fit to give Admifiion to the Water, which, when it comes to the Strata of the Stones, can penetrate no farther, but is there impeded and colleded into Drops, and breaks out into a Fountain among the Rocks, if it can find any Aperture. Moreover, the rocky Mountains in the Ifland of St Helena^ and in moft other Iflands, are not within fo denfe and obdurate, as appears from the Cinders, Afhes, and fulphu- reous Earth j which fhews that thefe Mountains fpme time or other burnt or fmoaked. And to this we may add, that the Fountain is not always- in the Place where the Water breaks out, which is conveyed very often from a higher Place, by a Cha- nel under Ground, and this caufes it to break forth with greater Violence, as is very often obferved. X4 We 312 Tloe Ahfilute Tart S e c t. I V. We may be further convinced of the Truth of thefe Things, by confidering that Fire will tend downwards thro' a Continuation of Matter, tho' dt it's own Nature, when it is free from Matter, it tends upwards. Thus if you put one End of a B^r of Iron into the Fire, it will penetrate thro* the whole, and heat the other End, tho' it be turned downwards. And this is fufficient to con- vince any one of the Invalidity of the firft Argu- ment-. T O the Second we anfwer. That the Reafon why the Sea- Water doth not penetrate and fink into the Earth towards the Center, fo much as into the Mountains, is, btcaufe the Earth there is den- fer, and full of Metals, as we find by Experience ; but where it is not fo obdurate, the W^ater glides in, and therefore if there are Receptacles under the bottom of the Sea, we do not deny but that there may be fome frefh and fidt Water Lakes there. But bccaufe there are few fuch Receptacles, and the Earth every where is denfe and metalline, un- der the bottom of the Sea, it cannot conftantly im- bibe Water ; but when it is faturated it receives no more, and then the overplus Water diflils towards the higher Places. And the Sea conftantly chang- ing it's Altitude, and fiudluating backwards and forwards, may contribute much to elevate the Wa- ter ; for where it is higher than ordinary, it muft certainly prefs the Water into the Earth, and drive it to the Fountain-Heads. And fince the Surface of the Ocean in every Place is conftantly agitated, and made higher and lower, not only by Storms, but alfo by the Tides, therefore fuch a Preflure as fhis muft happen every Day. But I queftion whe- ther this can do much. TO the third Argument we fay, That this is owing to the Difpofition or Situation of the Strata f rhe Earth, or of the Earth itfelf, and that it is C H A p. 1 6. of Jj7iiverjal Geography. 313 the natural of all Fluids to gather to a Head, where there is a Flux. I think there is no need of faying any more to this. BUT the fourth is not fo eafily anfwered, for we do not perceive Salt to be feparated from Sea- Water only by Percolation or Straining. Befide, there are two kinds of Salt in Water Cwhich the Arijlotelians did not confider) the one of which is very well named, by Chemills, fixed, and the other volatile. The fixed Salts may indeed, by continual draining, or boiling, or diftilling of the Sea- Water, be feparated from it ; but the vola- tile Salt is fo full of Spirit, that it flies up with the Water, and cannot be feparated from it, neither by frequent Diftillations nor any other Art hither- to ufed. Therefore it is very difficult to fhew how this volatile Spirit of Salt is feparated from the Sea- ■ Water, in it's PaflTagefrom the Ocean to Fountain- Heads. The following Accounts v;ill ferve our Turn. I. Tho' we have not found out the Art of feparating the volatile Spirit of Salt from Sea- Wa- ter, yet we cannot deny but that it may be done, fince we fee it feparated by Nature, when it rains frefli Showers in the main Ocean, tho' they pro- ceed from Vapours exhaled from the Sea. 2. The Particles of fait Water which pervade the Fifiures of the Earth, before they come to their Fountain, ar€ mixed with other frefh Water, which proceeds from Rain and Vapours condenfed there, whereby the fmall Degree of volatile Salt that remains in them is rendered infenfible, 3. It is not true that all Fountains are entirely deprived of Saltnefs, for there are fome fait Springs, as we faid before, a- bout two Miles from Suez, and in feveral other Places not fo far from the Sea. Therefore to fe-> parate the volatile Salt from the Water, a long Tranfcolation, and a gentle Evaporation is requir- ed, and thus it is to be feparated by Art ; and thus 314 ^^ Abfohite Fart Sect. IV. thus alfo is Rain- Water generated and made frelh ; tho* fometimes faltilh Showers are obferved to fall into the Sea. THE Water of Springs therefore proceeds part- ly from the Sea, or fubtcrraneous Water, and partly from Rain and Dew that moiftens the Earth. But the Water of Rivers proceeds partly from Springs, and partly from Rain and Snow. „ i.;;, "' 'proposition VI.

THE Alpheus, a River in Greece, is fwal- lowed by the Earth, and, as the Greek Poets write, takes it's Courfe under both Sea and Land into Sicily, where it rifes, as they fay, on the ^*)'- racufian Shore, and is the fame with the River cal- led Arethufa in Sicily (d). This they were induced to think, becaufe that this River, every fifth Summer, did cafl up the Dung of Cattle, at the fame Time that the Olympic Games were celebrated in Achaia, when the Dung of the flain Vidims was thrown into the Alpheus, which was therefore carried with a dire6l Courfe into Sicily. 5. T H E River Guadiana, between Portugal and Andalu/ia, (formerly called Anas) hideth itfelf (/, was formerly famous for carrying Gold-Sands at the Bottom: but there are none now j nor do I hear of much Riches got that way out of any River in Europe, tho' fome boaft of a fmall Rivulet in Hejffc, which has Gold mixed with it's Sand j but I have not read it in any Author of Credit. NO Rivers, which in like manner produce SiU ver, are taken Notice of by Authors ; yet it is not to be doubted but there are as many if not more of this Sort alfo; only becaufe Silver is not fo eafily difcerned from the Sand, and no great Profit is expected to requite the Pains of extra- cling it, no Body has thought it worth their while to take Notice of it. And for this Reafon there hath been no mention made of thofe Rivers that carry Grains of Iron, Copper, Tin, ^c. except ¥4 «f 328 "The Ahjolute Tart Sect. IV. of fome few-, iho' without doubt there are great Numbers of them in the World, at whofe fur- prizing effedls Men are amazed; and fuperficial Philofophershave here recourfe to occult Qualities. If we obferve the River in Hi^ Germany which turns Iron intoCopper fas iscommonly thought), we admire that a Horfe-fhoe of Iron fhould, by hang- ing in it for fome Time, be turned into one of perfe«fl Copper. Bur, in truth, the Iron is not changed into Copper (as is vulgarly fuppofed), but the Grains and Particles of Copper and Vitriol that are in this River, moving with the Water, corrode the Iron, whofe Particles being removed, thofe of Copper fucceed in their Places. NEITHER is there much Notice taken of fuch Rivulets as are impregnated with various kinds of Earth, Salt, and other Foflils, but we fliall treat largely of mineral and metallic Springs, in the fol- lowing Chapter. FROM this Mixture of different Particles pro- ceeds a ftrange Diverfity of Waters, in Rivers and Wells. Some Water if you boil Meat in it, makes it black, which is a Sign that it is impreg- nated with Iron ; nor will Peafe boil foft fo foon in this, as in other Water that is fomething fat and oily. Neither can the fame Beer be made of different Waters. That Water which hath Par- ticles of Iron in it we call hard Water; but if it be mixed with fat and oily Particles, we call it foft Water. The Elbe is a foft Water River, as we may call it, which fas Experience fhewsj is owing to the clayey and fruitful Ground it wafhes. And every other variety of Water arifes from the dif- ferent forts of Earth, thro' which the Spring or River is carried, whether it be clayey, rocky, c,r metallic, i^c, PRO- Chap. i6. of Unherfal Geography, 329 PROPOSITION XIX. ^he Waters of mojl Rivers differ in Colour ^ Gravity, and other ^alities.

THE Water of the River Ganges is accounted very light and wholefome, and the Emperor of Guzarat, or the Great Mogul, in whatever place he is, takes care that this Water be carried along with him in Bottles, of which he alone drinketh. Others will have the Nile to produce the fofteft and mod wholfome Water. Heavy Water is for the moft Part impregnated with Iron or Mercury. TO underftand the Nature of great Rivers we muft look into the Rivulets that compofe them ; (for the Rhine receives many mineral Rivers, and the Danube takes in fuch as carry Gold, Iron, Vitriol, ^c.) from whence their different Quali- ties arife, tho' moft Fpuntains have fomething of thcfe in them. PROPOSITION XX. Some Rivers, at a fet Time of the Tear, rife beyond their Banks, and overflow the adjacent Countries. THE firft and moft celebrated among thefe is the Nile J which fwells to fuch a degree that ic covers all 330 ^oe Abfolute Part Sect. IV. all the Land of Egypt, except the Hills. The Deluge begins about the feventeenth of June j and increafes forty Days, and decreafes as many, fo that at this Time, all the Cities, which are moft of them built upon Hills : appear like fo many Iflands. Antiquity hath given a large Account of this Inundation, becaufe in that Part of the Earth which was then known (before the eaftern and'weftern Parts were difcovered) no River wa^ found to be the fame, except the Niger, which therefore wasfuppofed ro communicate with the Ntk under Ground. Seneca has defcribed the In- undation of the Nile the beft of all the Antients, and therefore I cannot but give it in his Words. 'THE Nile (fays be) isincreafed in the middle * of Summer, from before the rifing of the little * Dcg-Star, to beyond the Autumnal Equinox. < Nature hath placed this moft noble River in the * Sight of all Mankind, and ordered it fo, that * it fhould overflow -Eg)'/)/ at aTime when the Earth, * being drieft with the Summer Heat, might fuck * in more of it's Water, and fufficiently quench * it's annual Thirft. For in that part of Egypl ' which lies towards Ethiopia there are few or no * Showers, and thofe that fall do not refrefli the * Earth, which is unaccuftomed to Rain-Water. * Egypt builds her whole hope upon this, and * is fertile, or barren, according as the River af- ' fords it more or lefs Water. The Hufband- ' man never minds the Heavens, and the Poet * Oviddoe^ not jeft when he fays. T'he Herbs hefeech not Jove to pour \x ■ Himfelf upon them in a Shower. * If we knew where it begins to increafe, we might « perhaps find out the Caufe of it's Increafe. But s after it had wandered over vaft Pefarts, and J * made C H A p. 1 6. of Univerfal Geography, 331 « made it's way thro' Fens and Marfhes, and un- ' known Countries, it collefts it*s diforderly Wa- * ters about Philas. The Ifland of Philai being on ' every fide rocky and rugged, is waflied by two * Rivers whicii there come together and furround ' the whole Ifland.Thefelofing their formerNames, ^ mixtogether and are called the Nile, v/hich being ^ increafed in breadth, glides gently from thence * thro* Ethiopia, and the fandy Defarts that afford * a Paffage to the Commerce of the Indian Sea. •* The Cararafls afterward receive it, which fill the * Eye with fomething great and amazing •, there the * Nile rufhes againft the broken Mountains in it*s ^ way, and is forced in to the narrow Paflages * and Hollows that are made in the hard Rocks, * dafliing againft the Stones that obftrud: it's Cur- * rent, and overflowing fometimes all the obftacles « that interrupt it. Here it's Courfe is obftru(fled, * which makes it rife in waves and furges : and * there it is confined between two Rocks, and frets « and foams to be enlarged •, fo that it's Waters, * which before glided gently along, beingnow put " into a violent Agitation, rufh from one Rock * to another, and make it appear more like a * Torrent than a River. Now it looks thick, mud- * dy, and troubled, and half covered with Froth, * which is not it's natural Colour, but owing to the * Injury of the Places it fiowed thro'. At length * having freed itfelf from all Obltacles, it falls on * a fudden from a prodigious Height, and with * a Noife dreadful to the Country thereabouts; * which a Colony that were placed there, by the * Perfians, could not endure; their Ears being * fo ftunned with the continual Noife, that they * were forced to tranfport themfelves to more * quiet Habitations. The incredible Boldnefs of * the Inhabitants is reported among the Miracles ? of thi$ River, They get into their Boats by * pairs 332 ^he Abfolute Part Se c T. IV. pairs, the one guides it, and the other throws out the Water, and after they have tumbled feme Time among the raging Waves of the Nile^ they get into the narroweft Chanels, and avoid as much as pofTible the dangerous Creeks in the Rocks ; then guiding the Boat with their Hands, they are carried headlong down the middle of the Current, by the force of the whole River, and when the Specftators are in great Fear, and begin to lament, believing they are overfet and drowned by the great Weight of the Water, yet they are in an inrtant feen failing a great way from the Place where they fell down, being carried as fwift as a Stone out of an Engine. Nor does the Boat in it's Fall overfet, but is carried fafe into the fmooth Water. The firft rifing of the Nile is perceived about the fore- mentioned IQe of PhiiaSy a little way from whence it is divided by a Rock (called, by the Greeks, Ahaton) which none ever afcend but their Ru- lers : there the rifing of the River is obferved and marked upon the Sides of the Rock. A great way below this there are two eminent Rocks, called, by the Inhabitants, the Veins of the Nile, from which a great Force of Water floweth i yet not fo much as to do any harm to Egypt. The Priefts throw Offerings in at thefe Mouths, and the Governours Gifts of Gold, while the holy Rites are performing. From this Place the Nile feems as if it had got new Strength, and is rolled along a narrow and deep Chanel, being hemmed in by the Mountains on each Side, and hindered from enlarging it*s Breadth, When it comes to Memphis, it is again at Li- berty, and wanders over the Country, dividing itfelf into Rivulets, and diifufing it*s Streams over ^\[ Egypt, thro' innumerable Canals, made by Art as commodious as pofllble. At firft it Chap. i6. of TJniverfal Geography. 33^ is divided, but the Waters being continued, ic ftagnates and appears like a large troubled Sea. The Breadth of the Country, thro' which it is extended, breaks the Violence of it's Current, being no lefs than the whole Land of Eg-jpK As much as the Nile increafes, fo much do their Hopes for that Year ; and the Hufbandman is not deceived who computes his product by the Meafure of the River. It brings troubled Wa- ter and Mud upon the fandy and dry Soil, and leaves it's Dregs and Filth upon the Ground that is moft chapped with Drought, and what- ever clammy Fatnefs it brings along with it, is fprinkled upon the drieft Places ; fo that ic manures the Ground two ways, by watering it, and covering it withMud •, but the Places it doth not reach are bare and unfruitful. If it increafe above fuch a height it does not fo well. The Nature of this River is alfo wonderful ; for when other fmall Rivers wafte and walh out the Fat- nefs of the Earth, the Nile, by how much it ex- cels others in Greatnefs, is fo far from wafting and eating out any Thing, that it rather adds new Vigour to the pining Ground, and at lead: puts it into a better Temper, by faturating the fandy Places with Slime and Mud i fo thac Egypt does not only owe the Fertility of it's Soil to the Nile, but even alfo the Soil itfelf. When it overflows the Fields, it makes a plea- fant appearance, for the Plains and Vallies lie hid under the Water, and the Towns, appearing like Iflands, are only to be feen ; and they have no Commerce one with another in the inland Places but by Boats ; the lefs alfo the People fee of their Lands, the more they rejoice. When the Nile is confined within it's Banks, it is poured into the Sea thro' feven Mouths, and every one * of them hath the appearance of a Sea, befides ' feveral 334 *^^ Abjolute Tart S e c t.

Theophrajius rclsiteSf that the Nile once brought down Sea-Water ; and it is certain that when Cleopatra reigned it did not rife for two Years, viz in the eleventh and twelfth Years of her Reign ; which they fay * portended C H A p. 1 6. of Ufiivejfal Geography, 3 3 j * portended bad Fortune to two great Perfons, * viz. to Aniori'j and Cleopatra^ who foon after * Joft their Empires. Callimachus relates, that the * Nile in former Ages did not overflow for nine * Years. ' N O W I come to enquire into the Caufe of * the Nile*^ overflowing in Summer, and I fhall * firft begin with the Opinions of the Antients. * Jnaxagoras was of Opinion, that the melted ' Snow is poured down, from the Mountains of * Ethiopia into the Nile, and makes it overflow ; ' and all the Antients believed this to be the ' Caufe ; JEfchylus, Sophocles, and Euripides, have * taught the fame. But this is evidently falfe * for feveral Reafons: Firft Ethiopia is the ' hotteft Country upon Earth, as appears from ' the tawny or Sun-burnt Colour of the Inhabi- ' tants, and the Troglodytes vfho build their Houfes ' under Ground: the Rocks alfo are as hot as * Fire, not only at Noon but even at the clofe * of the Day 1 the Duft under foot is fo hot that ^ Men cannot walk upon it ; Silver is unfoldered ; ' the Joints of Images are disjoined, and what- ' ever is laid on them for Ornament diflblves or ' is peeled off-, the South Wind, which blows ' from thefe Places, is immoderately hot, and ' thofe Creatures, as Serpents, (^c. that elfewhere ' ufe to hide themfelves in the Winter, never ' withdraw there, but arc found in the open Field ' all the Year. There is no Snow nor heavy ' Rain falls at Alexandria, which is a great way ' removed from thefe immoderate Heats. How ' therefore fhould a Country fubie<5i: to fo much ' Heat, be covered with Snow all the Winter ? ' Some Mountains indeed may have Snow on them * there, but no more than the Ridges of Thracia * or Caucafus ; and the Rivers that flow from thefe ' lafl:, fwell in the Spring, and the beginning of * Summer, 336 'The Abfolute Tart Sect. IV. * Summer, and are lefs again in Winter; becaufe * that in the Spring the Snow is waflied down * by the Rain, and if any is left it is melted by * the firll Heat of the Sun. Neither the Rhine, * RhojiCj IJler, nor Cayjler, are fubjedl to this ; they ' only are out a little in Summer, tho* the Snows * are very deep on the northern Mountains. The * Phafis and the Boryjihenes would alfo rife at that * time, if the Snow could produce great Rivers < againft Summer. Moreover, if this were the < Caufe of the Increafe of the Nile, it would flow ' mofl: at the beginning of Summer j for then ' the Snow^ being large and entire, is melted in ' greater Quantities. But the Nile is in it's Gran- ' dure four Months, and is then always the fame. ' If we may believe 'Thales, the anniverfary North « Winds refifl the Defcent of the Nile, and hinder ' it's Courfe, by driving the Sea in at the Mouths ' of it's Chanels, fo that being repulfed it runs * back upon itfelf ; and is not increafed, but be- ' caufe it cannot find a Paffage, it overflows and ' breaks out in every Place where it can make ' it's Way. Euthyinenes, of Marfeilles, fides ' with him, and gives this Tefl:imony : I have ' failed, fays he, in the Atlantic Sea ; whence the * Nile flows larger as long as the anniverfary ' North Winds blow, becaufe that then the Sea, ' being urged by the Winds, replenifh it's Stream •, ' but when they ceafe, the Sea grows calm, ' and the Nile returns with lefs Force. Befides, ' the Sea- Water is alfo fweet, and the Monfters ' in it refemble thofe of the Nile. But where- ' fore then, (fay I) if thefe Vv^inds make the Nile * fwell, doth it rife before they begin to blow, ' and continue after they are over ? alfo why ' doth it not grow greater when they blow ftrong- * er.'' for it is not increafed or leflened, when ' they blow more or lefs, which it fliould be, if 2 « it Chap, i 6. of Vniverfal Geography, 337 it depended upon their Force. Moreover, thefe Winds blow againft the Shores of Egypt^ and the Nile dcfcends the contrary Way againft them, but why (hould it not flow from whence they blow, if it hath it's Origin from them ? Befidcs, it would flow from the Sea pure and green, not troubled and muddy as it doth now. Add to this, that innumerable Witnelfes contradicSb this Teftimony, and tho' Men might lie fafely and put any Fables upon us, as long as the Coafts were unknown ; but now the foreign Coafts are frequented by Merchant-Ships, yet none of them mention the green Colour of the Nile^ or that the Sea hath any other Tafte than ufual ; which is alfo difagreeable to Nature, for the Sun evaporates the lighteft and frefiiefl: Particles. Befides, why doth it not increafe in Winter, when the Sea is fometimes raifed with greater Winds than thefe annual ones, which are commonly moderate -, and further, if it pro- ceeded from the Atlantic Sea it would cover Egypt at once, and not by Degrees as it does. Oenopides of Chios fays, that in Winter the Heat is kept under Ground, and therefore Dens and Caverns are then hot, and Fountain- Water is warm alfo, that the Veins of the Earth are dried up by the internal Heat ; but in other Countries the Rivers are repleniflied with Rain : only the Nile^ which is not fupplied with Rain, is lefTened in Winter, and increafes in Summer, when the interior Parts of the Earth are cold, and the Fountains are frefh and cool. But if this were true, all the Fountains would increafe, and riini over in Summer. Befides, the fubterraneous Heat is not greater in Winter, tho' Water, Caves, and Wells, are then warm, becaufe they do not admit the external cold Air ; fo that they are not abfolucely hot, but only exclude the cold : for L. L Z * this 338 lie Abfolute Fart S e c t . 1 V . *• this Reaibn they :ire cold in Summer, becaufe ' the hot Air is kept from them. Diogenes Jpollo- ' niates lays, that as the Sua draws Moilture to it, ' fo the dry and parched Earth draws it from the ' Sea and other Waters ; for it is impofiible that ' one Part of the Earth Ihould be dry, when ano- ' ther is moiil, becaufe it is all over perforated and ' full of Intercourfes, thro' which the dry Places « draw Moilture from the wet, other wife they ' would long fince have been burnt up. Eor this * Reafon, the Sun draws the Waters to it, and the * meridian Places that have moil need of it -, alio *■ where the Earth is mofl dried, it draws moft ' Moifture to it. As in Lamps, the Oil runs to- * wards the Place where it is confumed, fo the Wa- ' ter runs towards that Place where the Earth is * parched up with Heat. From whence therefore *• fnould it come but from the cold northern Parts? * Does not the Proponiis for this Reafon conftantly ' flow into the lower Seas, not as others do by a * Flux and Reflux, but by a conftant and rapid ' Courfe towards the fame Point ? And unlefs by * the/e Intercourfes, Places that wanted were re- ' pleniihed from thofe that abounded, the Earth ' would be foon dried to Duft, or laid under Wa- ' ter. I would willingly afic Diogenes^ why, fince ' the Sea and all Rivers meet together, they are ' not larger in all Countries in the Summer ? The ' Sun fcorches Egspt more than other Countries, ' and therefore the Nile increafes more : and in ' other Parts of the Earth there is alfo fome in- ' creafe of the Rivers. But I afl< him, why then * is there any Part of the Earth without Moifture, ' fince the hotter it is in any Place the more Moi- ' (lure it draws from other Countries ? And laftly, ' why is the Nile fo fweet, if it receives it's Water ' from the Sea ? For no Water is fo fweet as the * Water of the NiU: FROM C H A p. 1 6, of V?iherfal Geography. 339 FROM this Paficige of Seneca we gather the Opinions of the Ancients (efpecially of the Greek Philofophers) about the Caufe of the In- undation of the Nile. But none of them are true, becaufe in thofe times no Body had travelled out of Europe, fo far as the Springs of the Nile, or had vifited the Nations that border on them, which are very remote from Egypt. But the Matter is now well fearched into, and the true Caufe is found out, fince the Portuguefe, and alfo the Englijh and Dutch, trade with the Nations that border upon thefe Springs, in the Kingdoms of Congo ^ Angola, Sofala, Moza?nbique, (^c.

Near to this Lake are feveral Ridges ot Mountains, particularly thofe called the M cunt ains of the Moon ^ and of «St'/Zj, between v/hich the Lake licth as in a Valley among the Moun- tains. And becaufe thefe Places lie on the South Side of the. Equator, the Motion of the Sun re- quires that it fhould be Winter with them when it is Summer with us •, but by Reafon of their fmall Diftance from the Equator, they have little or no cold Weather, but Rain (inftead of Snow) for two Hours before and after Noon, every Day, in the Kingdom of Congo.

THE Time when the Nile begins to overflow, and alio when it ends, agrees with this Caufe ; for the Winter, or rainy Seafon, in Congo and the mountainous Places, begins in our Spring, about the middle of March or April fwhich is the Time of Autumn to them, viz. from Ma-j the Twenty firit to Jiore the Twenty firft) but is not fo ve- hement as in iW-3}', June., and Jul'^ : in Aiigujl and Seutemvsr it isalfo moderate, and ends in the mid- dle of September. The rifing'of " the A%, as was faid before, begins about the feventeenth of June in this Age. But Herodotus teftifies that the Nile^ in his Time, was a hundred Days in rifing, and as many in falling •, therefore it began to increafe fome Weeks fooner, viz. about the firft q\ June., or in May., and before that it muft have rained fome Time upon the Mountains, bordering upon the Lake, that is, from March to May or June. But the Reafon why it begins to overflow not fo foon now as formerly {viz. in the Time of Hero- dotus., when it feems to have begun in April) is becaufe the Nile, by bringing down Mud and ter- reft rial Matter, hath made the Ground, which it o- verflows, higher, and therefore the Chanel is lower and deeper (as well by this as by being fcoured by the rapid Current) and contains more W^ater than formerly, which is the Reafon that it doth not fo foon overflow it*s Banks. And no doubt but the Nile^ in a great many Ages, rnay not Z 3 overflow 342 I'be Ahjolute Part S e c t. IV. overPiOW ii's B.mks at all ; for, by a continual walliing down of the Earth, the Country is raifed and the Banks and Shores grow iiigher, and in Time may make a Chanel big enough to con- tain all the Water of the River when it is at it's Height. B U T we have liiid too much of the Nile, and more than we intended, THE fecond of thefe Rivers, that overflow the adjacent Countries at a certain Time of the Year, is the Niger, a River in /Ifrica, of no lefs Courfe that the Nile, iho' not fo famous. It over- flows at the fame Time that the Nile does. Leo Jlfricanus fays, it begifis to rife on the fifteenth of June, and incrcafcs forty Days, and decreafes as many. When it is at the Height, People may fail in Boats all over Negroland, tho* not without great Danger. T H E third River that overflows is the Zaire in Congo, as v/as faid before •, and to this may be referred other Rivers in the fame Country. THE fourth overflowing River, is the Rio de la Plata in Braftl, which waters the adjacent Fields at the fame Time with the Nile, as Maffem ob- ferves. THE fifth is the Ganges. THE fixth is the River Indus. Thefe two lafl: pour out their Waters upon the Earth in the rainy Seafon, viz. in June, July, and ^ugujl, when the Inhabitants gather the Water into Ponds, and pre- ferve it, that they may be fupplied at other Times of the Year, when there is almoft no Rain. This .Inundation makes the Land very fruitful. THE feventh includes a great many, viz. four or five that flow from about the Lake Caamay m moderate large Chanels, and exonerate themfelves into the Bay of Bengal, flowing thro' Pegu, Siam, and other Places. That River which waters the Royal Chap. i6. oflJniverfal Geography. ZW Royal City of Siam is called Mcnam^ and over- flows in 'September., Ooiober^ and November^ at which Time the Fields and Streets in the City are all covered with Water, fo that the People are forced to make ufe of Boats to iail from one Houfe to another. This alfo cauics an exceeding Fer- tility. 1' H E eighth is the River [^Mccon'] in Cambodia^ which overflows in Summer j but is not right placed in Maps. TFIE ninth is the River [^Paraguay., which is a Part of the Rio de la Plata] and overflows at the fame Time with ir, and the Nile. THE tenth includes thofe in Cormandel in /;/- dia, which overflow in the rainy Months, and are fed by the Rain that is poured from mount Gate. THE eleventh is the Euphrates, which over- flows Mefopotamia on fome particular Days of the Year. THE twelfth is the River oz/;, or Agus^ in Sufa ; which overflows in Winter. I do not remember to have read of any other Rivers, befldes thefe, that overflow annually at a ftated Period, tho' there are feveral that do it mofc Years, as the Oby, the [^Hoambo'] or Tellow River in China, ^c. THERE are many Rivers that overflow with- out keeping a fet Time, and indeed fcarce any of the larger Sort but what break over the Banks, at one Time or other, as the Elbe, the Rhine, the JVefer, i^c. And if it were not for the Depth and Capacity of the Chanel, all great Rivers would annually overflow •, for moft of them are vaftly in- creafed in the Spring. And it may fo happen, that a River which did not ufe to overflow may begin to do it yearly, if any Part of the Chanel be raifed higher by Sands, or otherwife, fo as almoft Z 4 to 344 ^he Ahfclute Fart Sect. IV. to equal the Height of the Banks. But to pre- vent this. Men commonly raile the Banks in pro- portion. T H E fole Caufe of thefe Deluges is the great quantity of Water which in fome Places is drain- ed from the melted Snow, and in molt others, proceeds from frequent Rains and violent Showers. Yet it is to be admired why the Indus and the Games fhould not overflow at the fame Time that the neighbouring Rivers do, which proceed from the Lake Chaamay ; tho' it may be thought per- haps that this ditierence of Time, is partly owing to the annivcrfary Rains in the adjacent Places, and partly to the Mountains that furround the Sources or Spring- Heads, as we faid of the Nik ; but to avoid Prolixity, we lliali forbear examining every Particular. 'Phe River [Aifiw'] near Parh^ m France^ fometimes fwells lb much, without any more Rain than ordinary, as to ovtifiow the Suburbs of St Marcellus, and do a great deal of Damage. THE Reafon why almoft all thefe Deluges make the Fields fertile, is becaufe the Water that overflows them is either melted Snow or Rain, which being light and fpirituous, and containing fulphureous Matter mixed with it in the Air, is more prevalent to make the Ground fruitful, and alfo more wholefome than mineral Water -, and that Rain-Water contains fuch Sulphur and Spirit, appears, i . From the Worms that are bred in it. 2. From it's quick Putrefaction. 3. p>om the chemical Diftillation of it. Yet there are fome Rivers that do not make the Land fruitful by their Inundation but rather barren, as the Loire in France ; whilfl: the Seyne, with it's fat and foft Waters^ makes the Land fertile. Chap, i 6 . of Univejjal Geography. 345 PROPOSITION XXI. 51? explain ho'HJ Springs break out oj the Earth. WE have fhewed in the fourth Propofidon, whence the Water proceeds that flows out at Fountains ; we now come to enquire how the Colleflions of Waters are made to fpring out of the Earth, which one would think could not be done without a violent Perforation of the Ground. But there are various Caufes that make way for a Spring : i. If there be a Cavity, or Receptacle, in any Place, the Water, of it's own Nature, and without any other Caufe, will diftil and drain into it, and, in procefs of Time, by conftantly pervading the Crannies and Pallagcs, will make them larger, 'till at laft the Cavity be lull, and overflow into a Rivulet ; and the lame may hap- pen if there is no Receptacle, if the Sprirg be up- on the Side of a Mountain, or even upon the Tc p of it. For this Caufe there are feveral Springs found in Woods, and fliady Places, where the Rain- Water moiftens the Earth ; and becaufe it is not fo foon evaporated by the Heat of the Sun, or a free Air, it draws to it by degrees the fecret Water of a future Fountain. 2. The Spirits that are mixed with the Waters yet in the Earth, and the Rarefa6tion of them whereby they take up a larger Spice, often remove the Earth, and make way for Fountains ; for Water is more fpirituous while it is hid under Ground : fubterraneous Fires alfo contribute much to it's Rarefadion. 3.

From this the Town acquired all it's Riches and Splendor, and to this very Day there is kept in the Stadt-houfe of Lunenburg the fame Hog quartered and fmoaked hanging upon a Beam, whofe Parts are grown fo thin, by length of Time, that they feem to be only Pieces of Leather.

To make Aquedudls that will convey Water with a moderate Celerity, they commonly deprefs the Chanel no lefs than half a Foot in five hundred, otherwife the Water will run too flow, or not at all.

Some confound this with, or wi-U have it to be, a Branch of the Aliary. h is in fome Places four or hve Leagues broad, but it receives ii's Water not fo much from Fountains, as from the Rains that fall upon the Mountains of Peru ; and therefore is no- thing nigh fo broad in the dry Seafons. This makes Travellers difligree in their Dcfcriptions of it. 8.

But we fhall here treat of them more fully, and explain their Caiijes, and alfo fet them in a clearer Light. PROPOSITION I. No Water is pure and elementary •, hut contains other Particles mixed with it, fucb as are found in ter- rejlrial Bodies ; and thefe are not only earthy^ hut alfo of various other kinds, as Oil, Spirits, ^c. But that is called Mineral Water zvhich contains fo many of thefe Particles different from the Nature of Water itfelf that from them it acquires fuch re- markable Properties, as affect our Senfes, and makes us take notice of it. A a 4 THE 3 6o The Abfolute Part S e c T. I V. THE Truth of this Propofition is apparent from Experience, and is proved as well iiom the different Tafres of the Waters as from Diflillation ; and all Naturalilts agree that there is no fuch thing in Nature as pure or fimple Water, or any other Element fcparatcd from others, becaufe oi the con- ilant and various Agitation of the Panicles of Bodies. But in mineral Waters fthat we may ccme clofer to our Suhjed) the caufc of this Mixture is their receiving the fpiriiuous Particles of he- terogeneous Bodies ; for Rain and the very Air itfelf that covers the Water, is impregnated with many different forts of Particles. ALL Waters therefore have a Mixture of Par- ticles of another Nature, tho' all have rot the fame Quantity of them ; and tho' there fiow into the Rhuidy the Danube^ and the Elbe, and into all great Rivers, feveral Rivulets impregnated with mineral Particles in fuch Quantities as to affecl tlie Senfes -, yet becaufe, befides thefe, there are many other Brooks that flow into the fame Rivers which are not impregnated with a fenfible Quan- tity of heterogeneous Particles ; and becaufe mod of their Water proceeds from Rain and Dew, therefore thefe heterogeneous Particles are not ea- fily difcovered in fuch great Rivers, tho* they are received by them -, but require to be feparated by Art, if we would., know their Taffe and Qualities. We therefore call that mineral Water which hath fome remarkable Property more than what is ob- ferved in common Water, or hath fo large a Mix- ture of heterogeneous Particles as fenfibly to alter ii's Tafte, x^.. ,^^,.u . PRO-^ Chap. 17. of TJniverJal Geography. 361 PROPOSITION II. Mineral IVatcrs are of three kinJs. SOME are corporeal, (we want a better Word for itj others Spirituous, and the reft both corpo- real and fpirituous. Thofe we call corporeal mi- neral Waters do contain fixed and folid Particles of Minerals and Foffils, which can be Separated from the Water, and ittn with the naked Eye ; and fuch as thefe are of two forts : Some carry large Particles of Minerals and FofTils, whicii may be perceived with little or no trouble in the Water itfelf ; nor are they properly fpeaking mixed with the Water : Such as thele we treated of in the fore- going Chapter, and have in them Grains of Gold, Silver, Cffc. and therefore are called auriferous, argentiferous, ^c. But fuch are not properly called mineral Waters, becaufe they have not thefe Par- ticles mixed with them, but feparate -, neither do they receive any Property or Qiiality from them : yet becaufe Men admire fuch Rivers and their Explication hath a great Affinity with the Defcrip- tion of mineral Waters properly fo called, wc thought fit to mention them under the fame Head ; to which may be added bituminous Foun- tains, ^^c. BUT corporeal mineral Waters are more pro- perly fuch as indeed contain lolid Particles of Foffils, but fo fmall and minute that they are entirely mix- ed, and cannot quickly be dillinguifhed by the Sight, unlefs they are made to fubfide by Art, or a long fpace of Time -, or by Concretion are brought to a vifible Mafs, fuch as Salt and fulphurcous Fountains, &c. and chemical Waters in which Metals are diffolved. SPIRITUOUS 362 llje Abfilute Tart Sect. IV. SPIRITUOUS Waters are thofe that con- tain only a volatile Spirit, fuch as is found in Mi- nerals ; but have no rtxcd Particles in them •, and therefore their Compofition can never be made vifible. W E call thofe Waters both corporeal and fpi- rituous, which contain not only fixed and folid Particles of Minerals, but alfo volatile and fpiri- tuous : Of all which we Ihall give Examples in the following Propofitions. PROPOSITION III. To explain how mineral IVaters are generated.- 1. IF the Water be carried under Ground with a rapid Courfe among metalline and mineral Earth, which is eafily loofened, it is evident that it wafhes Particles from it, and may carry along with it Grains of thefe Minerals ; and this is the Gener.uion of thefe corporeal mineral Waters that hold Grains in them. 2. IF the Minerals are imperfecfl and not fo clofely joined, as Vitriol, Sulphur, i^c. or even Salt, which of their own Nature eafily mix with Water -, and if a Rivulet, or Gut of Water, runs thro* Beds or Mines of fuch Minerals, or be fbrain- ed thro' them Cwithout a Chanel or Dudt in fuch a Manner as we explained in Propofition V. of the preceding Chapter) the Water when it breaks out at the Fountain will have fmall Particles of thefe Minerals mixed with it, and will be cor- poreal mineral Water, of a fubtile Compofition, according to the fmallnefs of the Atoms. Now whether the Water can in like manner diflblve or unite with itfelf the Particles of Metals, is to be queftioned, becaufe they are hard and folid, and therefore are not eafily blended with Water. I ^ acknowledge Chap. 17. of Umverfil Geography. 363 acknowledge this may be done, but not with fimple or common Water, but by a vitriolic and la!t Ipirituous Water, like the yiqua Fortu of the Che- niifts 1 for as Aqua Forth diiiblves Metals into A- toms, and eafily unites them with itfelf, fo that they do not fubfide at the Bottom, unlcfs they be feparated by^Art: in like manner when fuch VVa- ter runs thro' a metallic Earth, it may difTolve the metalline Particles and unite them with itfeif -, and thus are the corporeal mineral Waters of the fecond Sort, accounted for and explained. 3. BEFORE Metals are formed in the Bowels of the Earth, Steams and Vapours are condenfed about the extant Corners of the Rocks, to which they ftick fall ; being at firft but of a foft Sub- ftance, though they are afterwards hardened by degrees ; if therefore the Water fhould run or gleet thro' the Places where fuch Vapours are in Commotion, it is impregnated with them -, and thus ipirituous mineral, and metalline, Waters are produced. Imperfedl Minerals alio make mineral Waters of their own Nature, alter another Me- thod ; vix. when, being heated by a fubterraneous, or their own proper, heat, they fend forth Spirits and Vapours, as Sulphur, Vitriol, Salt, Coal, i^c. And fuch Fumes and Exhalations are always ftir- red up where there are fuch Minerals ; among which the permeating Water is impregnated with that Spirit. Some think thefe fpirituous Waters may be generated by being only carried thro' a metallic Earth, or by having their Receptacles in it, or in their Mines ; but it is found to the con- trary by Experience, that Water receives no Qua- lity from Metals and Minerals, tho' they fiiould be immerfed in it a great many Years. There- fore, rejefling this Opinion, it is mod reafonable to fuppofe, that thefe Waters receive a certain Spi- rit, from the Seeds of Metals, or firft Principles, as 364 1^^(^ Akfolnte Tart S e c t. IV. as we may call them ; or we may fay that fuch "Waters are impregnated with the lubtile Spirits of Vitriol, Salt, i^c. by the help of which a Spirit is extra<5ted from hard Metals •, but I do not lay fo great Strefs upon this latter caufe ; for a Queftioni will arife again about the Generation of this fpiri- tuous, mineral, vitriolic, and fait Water. FROM thefe together it appears, how mine- ral Waters, both corporeal and fpirituous, are ge- nerated. P RO PO S IT'IO N IV. There are innumerable Kwds of mineral IP^alers, ac^ cording to ihe Variet\ and Diverjjty of the Particles, they receive from different Minerals. WE have fhewed and explained in the former Propofition, how mineral Waters receive thefe Particles ffrom which their extraordinary Qualities arifej from Minerals, or Fofiils. Now becaule there are divers Kinds of Minerals, it hence follows, that mineral Waters are various, and almoft infinitely different in their Qualities-, not confifting of one kind of Water impregnated with only one fort of Mineral, but of various Kinds, mixed with various Sorts. Wherefore mineral Waters are either fimple or mixed i and the Mixed have two, three, four, or more, forts of FofTils in them. HENCE are, i. Metallic Waters, as of Gold, Silver, Copper, Tin, Lead, Iron, &?r. 2. SALT Waters, as of common Salt, Nitre, Alum, Vitriol, i^c. 3. BITUMINOUS Waters, fulphureous, antimonial, as of Coal, Ambergris, ^c. 4. WATERS proceeding from various kinds of Earth and Stones, viz^ Limeftone Waters, (which receive Chap. 17. of Univerfil Geography. 365 receive Particles of Lime- Stones) Chalk, Oker, Cinnabar, Marble, Alabafter, ^c. 5. MERCURIAL Waters, i^c. ALL thefe kinds of Waters are to be under- ftood three Ways, as was faid in the fecond Pro- pofition (as all other mineral Waters are), viz. I. Some of them are corporeal, cither fenfibly fo, or by a refined and fubtile Commixture. 2. Others are ipirituous. 3. Others are both corporeal and fpirituous. Thefe Ditt'erences may be applied to the feveral Kinds of mineral Waters. For Lxample : There are Golden Waters which are, i. Corpo- real, that carry Grains of Gold, of fuch Magni- tude, that with fmall Trouble they are difcernable, by reafon of their grofs or courfe Mixture. 2. Cor- poreal, that carry very minute Particles of Gold, well mixed with them ; and tho' the fmalleil Par- ticles of Gold, do of their own Nature fink to the bottom in Water, yet that there are fuch, appears from the Aqua Regia of the Chemifts, in which Gold is diffolved into Atoms ; but this Aqua Regia is not a Simple Water, neither does any Water carry Atoms of Gold in it, unlefs it be before im- pregnated with other mineral Particles. 3. Spiri- tuous golden Waters, that have engendered a Spi- rit and Vapour in the Earth from which Gold is produced. 4. Golden Waters that are both corpo- real and fpirituous, viz. that have both Atoms of Gold, and the Spirit that produces it. THUS we are to apply this four- fold Variety to all forts of mineral Waters, whether fimple or mix'd (from whence innumerable Species are pro- duced; for either the Bodies of Fofiils, or their Spi- rits, or the Body of one FofTil with the Spirit of ano- ther, are mixed or engendered in the Water) : fo Lea- den Waters are ot four kinds, viz. i. Vifibly cor- poreal. 2. Corporeal by a fiibtile Mixture. 3. Tin- diured by the fpirit of Lead. 4. Im.pregnaied both with ^66 ^e AhfoJute Tart Sect. IV. with the Body and Spirit of Lead. And thefe four Participations ot Minerals are to be apph'ed to mer- curial Waters, i^c. and more efpecially to fait, vitriolic, and fulphureous Waters, becaufe in thefe, Nature icfelf difplays a four-fold Variety ; tho' it is to be doubted, whether there be corporeal Par- ticles of a fubtilc Grain in metalline Waters. Spiri- tuous metallic Waters are alfo very rare ; but the Water of Salt, Sulphur, ^c. both corporeal and fpirituous is very common, becaufe thefe Foflils are found in more Places of the Earth, and in greater Plenty, and their Particles are alfo fooner dafhed to Atoms, and diffolved by the Water ; befide they frequently emit Steams and Vapours. LET us explain this four-fold Variety of Par- ticipation by one Example of Gold. I. IN the preceding Chapter, Propofition xvi, we enumerated thofe Rivers that carry Grains of Gold, and with this Treafure glad the Hearts of the Natives upon their Banks •, as in the County of ^yrol, and the neighbouring Places, there are fe- veral fuch -, and as we fiid before, the Rhine, the Elbe, the Danube, and feveral other great Rivers, carry Grains of Gold in feveral Places (and alfo other Metals and Minerals) which they receive'from auriferous Rivulets, T. he Rhifie carries Grains of Gold, mixed with Clay and Sand, in many Places, but efpecially at thefe, viz. i. Near Coire, in the Grifons Country. 2. At Mayenfelci. 3. At EgUfau. 4. At Sokings. 5. At the Town of AugPl, not far from Bafil. 6. At Newhurg. 7, At Seltz. 8. At JVormu 9. At Mentz. 10. Az Bacherach, 11. At Bon, i^c. The auriferous Rivulets, which the Rhir.e receives, the Reader may fee in Tburnheuferus ; and alfo thofe that run into the Danube, and Elbe. Small Grains of Gold are found in the Elbe in thefe Places : i. At Lolomcritz in Bohemia. 2. At Purn. 3 . At Drefdcn in Mcifen, 4. At Torgaw. 5' At Chap. 17. of Utiiverfal Geography. 367 5. At Magdeburg. 6. At Lavenburgb Tower, five Miles from Hamburgh. Several otiier auriferous Rivers are given an Account of in the forecitcd Book of '■thurnheufcrm ; and fuch as carry other Metals and Minerals. And thefe are auriferous corporeal Waters, of the firft kind, carrying vifi- ble Grains, which are not fo properly called Mine- ral or Golden Waters, becaufe the Gold Grains are not mixed with the Water, bur only carried in it by it*s rapid Motion ; the Water itfelf being un? compounded with it. .^, j 2. CORPOREAL Golden Waters of fine Mixture, whofe Atoms arc united with the Atoms of Gold, like the Aciua Rcgia of the Chemifts, which diffolves Gold, and unites it by Atoms to it- felf. For fmce it is pofTiblc that there may be in Nature fuch Water as this of the Chemifts, which may run thro* Golden Earth, or Gold Mines, it is reafonable to fuppofe, that it eats out Particle? and difTolves them into Atoms, and unites them to itfelf; and from this Caufe proceed thofe Cor fuch like) Golden Rivulets as are defcribed by "ithurnheuferus^ in his Account of the Danube^ Rhiney 3. SPIRITUOUS Golden Waters are but very ^Qw, fome of which perhaps are enumerated among the reft by Thurnheuferus ; but thefe are not (o much known or regarded, becaufe Golden Earth and Gold Mines are very fcarce ; befides where there are fuch Mines, there is fuch a Mixture of other Minerals, that they are not percvptible. Ncver- thelefs there are fome Rivulets in the high Jlpsof Bohemia, that are faid to participate of thefe Gol- den Spirits, as in the Fiechtelberg Mountains in Si- lefia. The Hoi Baths alfo in the Bifliopric of Coire^ are believed to be impregnated with this kind of Spirit, yet becaufe of the Mixture of other Mine- rals 368 TJje Abjolute Part Sect. IV. rals in a greater Quantity, this quality is rendered Icfs percepcible. 4. GOLDEN Waters that carry both the Atoms, and Spirit of Gold, are Ibme of thofe Rivulets mentioned by the above-named fhurnheu- ferus. L ET us alfo give an example of fait Waters. 1. CORPOREAL fait Water, which carry grofs and undigefted Particles of Salt, are found in many Places, and fufficiently known ; as Foun- tains, whofe Waters produce Salt •, and Sea- Water from which Salt is extracted by boiling. 2. SUBTLE corporeal fait Waters, which contain Salt diiTolved into the minuteft Atoms, are fuch as are very fait, and yet very clear, as many fait Fountains are, and Sea-Water that is thin and fine ; tho* there is a great Difference in this fubtile Mixture. Hereto may be referred the Urine of all Animals. 3. SPIRITUOUS fait Waters, which do not contain the Particles of Salt, but only the Spi- rit of it, are of fuch a Nature, that if feveral Tuns be ever fo much boiled, they will not yield any Salt. There are a great many of thefe in Germany, and other Places, but they are feldom without Mixture. 4. CORPOREAL and fpirituous fait Wa- ters, which contain the Particles and Spirit of Salt. Almoft all corporeal Waters have feme fmall Por- tion of filine Spirits in them, but few of them any Quantity. Thlrs the Fountains about the City Salt- xmge^ near the Rhine^ are filter than other fait Springs, and yet yield lefs Salt, becaufe their fharp and brackifii Tafre is heightened by a Spirit or vo- latile Salt, which flies away in the boiling.

They proceed from a Mixture ot the Spirit of Vitriol, Salt, and Alum •, which Minerals are found partly fimple, and partly mixed, with others more or lels, in the Bowels of the Earth, elpecially with Steel and Iron. We prove this to be the true Caufe of Acidiilce. i. Becaufe almoft wherever thefe acid Fountains break our, there are found Mines of Vitriol, Salt, and Sulphur. 2. Becaufe the Spirits of Vitriol and Sale are acid, and alfo the Spirit of Sulphur, as appears from Chemiftry. 3. Becaufe no acid Body can be drawn from thefe AcidulcBy but only a Spirit which is no way unlike the Spirit of Vitriol, Salt, i^c. THERE is plenty of Jcidulce in moft Coun- tries, efpecially thofe that abound in Mines. In Germany alone, their Number amounts to almoft one thoufand. Their Caufe is an acid Spirit which is found in moft Bodies, and in all Herbs and Fruits. T H E diflerence o'i Aciduhe is remarkable : Some are fo acid, that Men ufe them inftead of Vinegar ; fuch a Fountain as this is found in the Province of Nota^ m Sicily ; and another of a remarkable four- nefs at Elbogen in Germany, Other Fountains are called vinous becaufe they come near the grateful Relifh of Wine ; of which kind there is a famous one at Schwalbach, in the County of Catzenellebogen in Germany {a). There is a Spring near St Bal- domar, (a) Such like Chalybeates or Acididiv or Zour Waters ; for ^«wi art not fo properly called they do not contain any rough, vitriolic Chap. \j. of Univey-fal Geography, 371 dotnar, in the Province of Lionnoii in France^ cal- led la Fontaine forte^ whicli lupplics the w:int of Wine i for if one fourth Part of it be mixed with Wine, it will want nothing of it's right Talte and Relilh ; if it be poured on Flower, it will imme- diately ferment ; tlicy can boil no Meat in it, be- caufe through the Subtility of it's Spirit, it foon evaporates i it is fo extraordinary whcUfome^ that the Inhabit arJi thereabouts feldom Jland in need of a Phy^ fician. N O T far from the Town of Bazas in Guienne, there is fuch a Fountain, of a fharp vinous Talle, whofe Waters, if they are mixed with a fixth Pare of Wine only, will drink like neat Wine, without the leaft mixture of Water. Near Ro7ne there is a fliarptafled Alum-Fountain, whofe Waters being mixed with Wine, make a very agreeable Liquor. There is a great Number of liich Jcidtilce in High Germany ; fome Part of which flow into the Danube and fome into the Rhine. There are feveral of thefe in the fore- mentioned County of Catzenellebogen^ m the Ele6lorate of Triers^ in Tyrol^ in the Grifons vitriolic, or acid Salts to make them taile fliarp or four, but ra- ther leave a Iweetifh Flavour or Farewel behind ; and tho' at the firfl: thought one would afcrrbe a fharp or ibur Tafte to the Pyr- mont, Spai.v, or Tunhridge^ Wa- ters, yet if they be rightly con- fidered it is their iniart briflc Tafte that mifleads us to think them acid or truly four.

THE Studious may colled a great many Ex- amples from Authors. There are no lefs than two hundred acid Fountains or Rivulets, that flow into the Rhine \ but becaufe of the Subtility of their Spirits, the Rhine does not tafte acid in the leaft. I F any fhonld enquire.

For thefe fo that It is likely the Springs are brought thither by Art : Whence probably was the Ne- cromancy which the ]*copI,i of anticnt times believeJ, and re- ported to have contrived, and made thefe Baths ; as in a very antient Manufcript Chronicle J find thefe Words : When Lud Midi bras was dead, Blidud a great Nigromancer was made King; he made the Wonder of the Hot Bath by his Nigro- mancy, and he reigned twenty one Years, and after he died, and lies at the NeivTrcy. And in another old Chronicle 'tis faid: That King Bladud fent for the Necromancen to A- thens to eff^ed this great Buji- jiefs ; who, 'tis likely were no other than cunning Arti- ficers well fkillcd in Archilec- iure and Mechanics.^ this from Mr jfofeph Glan-viTs De- fcriptio?i of Bath, in Philofoph.

Bodies Queen's Bath is not fo hot, having no Springs of it'sown, but receives it's Water from the Kings. The Crofs-Bath is fomething colder than the others, and eats out Silver ex- ceedingly ; a Shilling in a W-eek's time has been to eaten by it that it might be wound about one's finger. InSum- mer they purge up a green fcum en the top, and in Win- ter leave a Yello^w one on the Walls. The Walls that keep in the hot Springs are very deep fet, and large ; ten Foot thick, and fourteen deep from the Level of the Street. The Cement of the Wall is yellow Clay, Lime, and beatcnBricks. In the Year 1659, the Hot Bath (one particularly fo cal- led of equal Heat with the Kings Bath) was much im- paired with the breaking out of a Spring which the Workmen at lafl found, and reftored. In digging they came to a firm Foundation of faftitious Matter which had Holes in it like a Pumicejicne, thro' wliich the /f«/rr plaid ; Chap.

Vitruvim tells us, that there were Fountains in the Ifland of Zant^ and about D\rrhachiia?2, now Durazzf), and Jpollonia^ that vomited out a great deal of Pitch with the Water.

Many fuch Fountains of Petro- hum, and oily Subflances, are now to be met with up and down ; as at Pitchford in Shrop- pire, and in the Ifland oi7,ant, very plentifully ; in the Valta- liiie, fubj'cl to the Grijans ; at tjie Foot of Mount Zebia in the Duchy of Modena ; at Gahian in the Road from MontpeUier to Bt'z.iers in Langucdoc. The Inhabitants living near thefe fat oily Springs, take Caretogather and ieparate the Bituminous fub- ftance frojn the Water ; They gather it with Ladles, and put- ting it into a Barrel, feparate the Water from the Oil by letting out the iirft at a Tap towards the Bottom of the Vefi'el. In the Ifland o{ Barhadocs there is a Rivulet, called Tugh Ri'ver, which hath upon it's Surface in many Places a certain oily Sub- ftance, which being carefully taken off, and kept a little Time, is fit to burn in Lamps like ordinary Oil. Near Cape Hclenc in Peru there are Foun- tains of Rofm (orfomethinglike it) which flow in Abundance. broad Chap. 17. of U?iiverfal Geography. 2>77 broad Lake, called Jf/JjalUUs Limne, that had a liquid Bitumen fwimming upon it, with which Stmiramis cemented the large Brick- Walls which furrounded Babylon. At this Day there is a Foun- tain near Degemfce^ a Monaftery in Bavaria^ whofe Surface is covered with Oil, whicli is daily carried away by the Natives. There are alfo great Lakes in Syria and Africa which fend forth Heaps of Bitu- men. The Acidul(B at Schwaibach if they be kept quiet in a Veifel for fome Hours, there will be Imall Drops ot Oil fwimming on the Top of them. A greater quantity of fuch Drops are found in a Fountain called Oelbriam near the Village Lam- ferfchlocb not far from Hagenaiv. And in mofb Baths there are found bituminous Particles, after they have (lood to fettle for fome Time -, as in the Petrolean Baths in the li.\v\^yf\o\vio^ Naples. THERE are alfo great Numbers of Foun- tains which do not produce Oil on their Surfices, but pour out ameer fat or bituminous Liquor. Near Gerfiach in the Valley called Lrbrrflhal., there flows from an old exhaufted Mine a thick Oil or Bitumen, which the Country People ufe inflead of Greafe to the Axle- Trees of their Wheels, but they are ignorant of it's fuperior Virtues ^ for I'hernheuferus itWs us, that an excellent Balfam may be prepared from it. In the Ifland Sumatra there is a Fountain which pours out a kind of liquid 'Petroleum: ibme lay it is a kind of Baliam •, there are faid to be alfo Fountains of Ambergris there. They find a bituminous Fountain in Peru near the Sea, which emits a fmall Rivulet into it, and is ufed by the Inhabitants inftead of Pitch -, neither have they any other fort of Matter fo like it. Not far from Schimachian in Perfia, at the Foot of the high Mountain Barmach, there are about thirty Fountains that fend out a Naphtha or bituminous Subffance :, but they lie low, and fpring with great Violence into 378 "^he Ahjolute Fart S e c T.

O N the Shore of Cormandel in India there are feveral Springs and Wells whofe Waters are bitter tho' they fpring up among the Rocks. In Pontus, a Province ol" y^fta miner, there is a fmall Rivulet at the Town of Callipade, called Exampean, whofe Water is bitter ; this makes the River H\panis alfo bitter, into. which it flows. The Reader may col- left feveral more Examples. THEY come from an impure Sulphur, Bitu- men, Nitre, Copperas, Copper-, as Water by long flanding in a Copper Vefiel, acquires a bitter tafte. But I cannot credit what Molina delivers in his Defcription of Gallicia, viz. that there is a Lake in Ireland whofe Waters are one half of the Day fweet, and the other half bitter.

In the Ifland of Haynan near China there is a Water of fuch a ftrang equality, that it petrifies feme fort of Fifhes vviien they unfortanatel/ chance to enter into it. Among thc^uckjil-vcr Mines in Guiaiui- I'ilica in Peru, is a Fountain of hot Water whofe Current hav- ing runa confidcrabic way, tarns at iafl into a foft kind of Rock, which being eafily cut, i.n-gima, &rc. a Lake, 382 1'he Ahjohite Fart S e c t. I V. a Lake, there flows a petrifying Fountain. Vitru- v'lui tells us that there is a broad Lake, between Mdzacca and Tuana in Cappadocia, which changes a Reed or a ftick of Wood, in one Day, into Stone. There is a Fountain near Charles's Baths in Bobetnia, in which if Wood lie long it is turned into Stone. Such as thefe are iound in divers other Places. Other Waters are thought to change Iron into Copper, which in fad they do not, only be- caufe thefe Waters carry the Spirit and Particles of Vitriol and Copper, they eat out, and by little and little dilTolve, the Particles of Copper as they flow along with the Water. THE Caufe why thefe Waters turn Wood into Stone is, i. Some do not change the Wood itfelf into Stone ; but the earthy, ftoney, faline Par- ticles contained in the Water flick to the Wood, and only incruftate it with a ftony Cruft. 2. O- thers do not change the Wood into Stone, but give it a hardnefs equal to that of Stone. 3. If any Water have a true petrifying Quality, I fup- pofe it may be accounted for thus (h).

But in Stone the Particles, being as it were Sands or Atoms, arc not joined by any extended Fibres. It therefore it be the Nature of any Water to difTolve, and, as it were, grind the long fibrous Particles of W^ood, that they do no more cohere after this Manner, but are ftill more condenfcd, the DiMerence between it and Stone will not be fo great as to be dif- cerned by the Eye ; yet it is probable that thele * I am the larger upon this, becaufe it feems to point out the truereafon of Petrifaclion; for is it not hence reafonable to fuppoie ? that the Water gleeting down the fides of the Toft Stone, corrodes the minu- teil of it's Particles, and is im- pregnated with them ; which are again feparated from the Water, by putting iticks of Wood into it, (by the Power of Attrafting) as we fee fome kinds of Salt feparated from Water by the like Means, and other Bodies feparated fromthofe that are compound- ed with them, by fuch as are found by experience to attraft their Particles. Now when thefe Particles are fo minute and fubtile, as to intrude with the Water into the Pores of the Wood, inprocefsof'1'ime, when it is throughly foaked, the Intcrllices will be quite filled with ftony Particles; and .if any thing ligneous remain, it is ib well guarded and in- cruilated by thefe Particles that it is not perceptible, nor to be adled upon by Fire : but if (as in the prefent Cafe} the Particles are not fo minute as to penetrate the Pores of the Wood, they only Hick clofe to theoutfide of it, and parget it over (as it. were) by degrees to a confiderab'e thicknefs. * What ftrengthens this Opi- nion very much is ; that tlie Particles of the Cafe or Crull, when ground to powder, are, to all appearance, like the Particles of the Stone from whence the Water drops, only the later is Ibmething whiter and rounder. ' Is not therefore fuch fub- terraneous Earth as this, thro' which tJie Water, of fuch like Qualities, runs, the Caufc of Fetrifadion ? ' Becaufe we may gather from hence the Reafons why. Fountains petrify fome forts of Wood throughout, but not others ; alfo why fome petrify only the Bark, Sap, or foftclt Part, and others only incale it, i^,c. mineral 384 'The Ahjolute Part Sect.

Others are generated from the Salt contained in the Bowels of the Earth, by pervading the Pla- ces where it lies, and mixing with it's Particles and Spirits, before they come to the Fountain. Salt Fountains are very common, and known to every one.

The like bubbling of Water is found round about Peroul, upon the Sea-Shore ; and in the Etang itfelf. There is a fiimous boiling or filming Well near Wigan in LancaJ}:>lre, with which you may boil an Egg, and upon theapproac'iing of a lighted Candle, it takes Fire. One like this was difco- vered in the Year i 7 1 1 , at Brofelffy, near Weitlock, in tlie County of Salop : It was hrll found out by a terrible uncom- mon Noife in the Night ; tlic Noife was fo fjreat, that it a- wakcned feveral People in their Beds, that lived hard by, who got up to fee what it was, and found the Earth to rumble and fhake in a Place near the Se- ei'ii, and a little boiling up of Water tiirough tlic Grafs.

To prevent the Spring being dellroyed, there is an Iron Ci- ftern placed about it, with a Cover upon it to be locked, and a Hole in tlie Middle there- of, that any who come may fee the Water through. Ifyou put a lighted Candle, or any thing of lire to this Hole, the Water takes fire, and burns like Spi- rit of Wine or Brandy. Some People out of Curiolity, after they have fet the Water on Fire, have put a Kettle of Water over the Ciflcrn, and in it a Joint of Meat, and boiled it much fooner than over any ar- tificial Fire that can be made. Yet what is molt ftrange, the Water of itfelf is as cold as any Water can be, even juil when the Fire is put out.

In June, 'July, and fometimes not till Augiijl, the Water runs away, and finks under Ground, not only by Percolation, or fal- ling through the Pores of the Earth, but by retiring under Ground, thro' many great Holes at the bottom ; the little, if any, that remains in the hilly or rocky Part, is evaporated ; and in O^o- ber or No^^emb. it moll common- ly returns again (though not at any certain Time) and foon co- vers the Tradl of Earth again. This Return and Afcent is fo fpeedy, and it mounts at the Holes with fuch Violence, that it fprings out of the Ground, to the height of a Pike. The Holes are in the fhape of Bafons or Cauldrons, which are notofthefameDepthorBreadth, being from twenty to h.xty Cu- bits more or lefs broad, and from eight to twent)- Cubits deep. In the Bottom of thefe are feveral Holes, at which the Water and Filhes enter, when the Lake ebbs away. Thefe are not in foft or loofc Earth, but com- monly made in the folid Rock. The Lake being thus every Year wet and dry , ferves the In- habitants for many purpofes. For iiril, while it is full of Wa- ter, it draws to it feveral forts of wild Geefe and Ducks, and other Water-Fowl, which may be Ihot, and are very good Meat. 2. As foon as the Lake is emptied, they pluck up the Rufhesand Weeds, which make Litter for Cattle. 3. Twenty Days after it is fully dry, they cut a great Quantity of Hay upon it. 4. After the Hay is in, they plow it, and few Miller, which generally comes to jMaturity. 5. There is great Variety of Hunting ; there coming cut of the neighbouring Woods and Mountains, plenty of Hares, Foxes, Deer, Swine, Bears, ^V. fo foon as the Water is gone- 6. When it is full, one may Fi{h in it. 7. All the Time when the Water goes awav, it yields great abundance of Fifh, which they catch in the Pits and Places, where the Holes are not big enough to admit them un- der Ground. Laflly, when the Water returns, it brings a fort of Ducks with it, which are bred under Ground, and when they hrll come out can fwim well enough, but are ilark blind, and have few or nofe-Tthers on them. They foon fee after they come into the Light, and in a fmall time get their Feathers, being much like Wild-Ducks, and are of a goodTafte,and eafilycaught. The Caufe, or rather Modus^ of all thefe wonderful Phxnome- ne in this Lake, is fuppofed to be, a Lake {"jiz. a fubterrancou^ cnr) under the Bottom of this 394 7?'^ Ahfohte Fart Se CT. IV. SO the Pool or Lake of Maron^ between the Sea ot Galilee^ and the City Delena^ is lb dry in Slimmer^ that it brings forth tall Herbs and Shrubs, yielding fiieker to Lions, Wolves, and other wild Beai\s. i N Guienne, near the Church of St Jean ^ An- gdi, there is another that hath almoft no Water in It in V/inter^ but abundance in Summer. THE like is found in Spain^ about twelve Miles from Valladolid, which begins to flow in Ma^, and sives over in November. ALL hot Baths flow without ceafing, except thofe, already mentioned, in the Grijom Country. with which it communicates by the feveral Holes defcribed. There are alfo one or more Lakes, under the bordering Mountain yavomkk, but whofe Surface is higher than that of the Lake of Zirchnitz. This upper Lake is poflibly fed by foraeofthemany Rivers, which in this Country bury them- felves under Ground. When it rains, efpccially in Thunder- fhowers, which are the moft hafty, the Water is precipita- ted with great Violence down the fleep Vallies, in which are the Chanels of thefe Ri- vulets ; {o that the Water in this Lake being increafed by the fudden coming of the Rains, fafter than it can empty, fwells prel'ently, and finding feveral Holes or Caverns in the Mountain higher than it's or- dinary Surface, it runs over by them into the fubterraneous Lake under that of 7ArchnitZy into which the Water comes up by the feveral Holes or Pits in the Bottom thereof, as like- wife by vifible Paffages above Ground.

I'd enquire how much of the Surface of the terraqueous Globe, the Earth and Water ftverall'j take up. IT is impoflible to know this accurately, becaufe we are ignorant of the Situation of the Earth and Ocean, about the North and South Pole, and becaufe their Superlicies are terminated by irregular and crooked Lines, not eafily computed or mea- fured. But fo far as we can guefs, from a bare Infpe(5lion of the Globe, it feems that the Super- ficies of the Earth and Water are nearly equal ; each taking up half of the Globe's Surtace. PROPOSITION II. ^he Surfaces of the Earth and Waters, are not always equally extended, hut fometimes more, and fotnetimes lefs ; and what the one lofes the othir gains. THE Sea frequently breaks in upon the Land in feveral Places and overflows it, or waftes it by degrees, and wafhes it away j by which means it's 396 Tl.-^e Ahfohte Fart S e c t.

PROPOSITION III. 7(7 compute bow much Earth and Water the terraque- ous Globe contains. T O find this accurately there ought to be known exaftly the Surtace of the Water -, and ii*s Depth in different Parts of thf; Sea, and alfo the Bulk of the fubterraneous Waters. All which we are ignorant of, and have no method to find them ; and therefore are at a lofs in finding the true quantity of either Earth or Water. We may form an Hypothefis, and take the Superficies of the Water for half the Superficies of the whole Globe, and alfo I'uppofe the Sea to be a quarter or half a Mile deep. Cone Place with another) not reckoning the Water in fubterraneous Ca- verns. T H ES E being granted, the quantity of Wa- ter is found thus : Take a quarter or halt a Mile from the Semidiameter of the Earth, and find the Solidity of a Sphere, whofe Semidiameter is equal to the Remainder. This Solidity being taken from the Solidity of the whole Globe, half the Remain- der is the quantity of Water. This lafl being a- gain fubftraded from the Solidity of the Globe, leaves the quantity of Earth, to which, for the Mountains, you mud add a fourth or fifth Part of the Bulk of the Water, or even a half: yet all Chap. i8. of Vniverfal Geography. 297 all this is but guefs-work, and not to be depended upon for Truth, PROPOSITION IV. The IFater viaj leave the Shore, and the Places of the Earth which it covered before, for fever al Rca- fons ; fo that the dry Land ?)iay appear where it was IVater or Sea before^ and a new Plat of Eartb may feem to be formed. T R A C T S of Water are feven-fold ; r. The Ocean. 2. Bays. 3. Seas or Streights. 4. Rivers, 5. Lakes. 6. Ponds. 7. Bogs. THAT Bogs or Marjfhes may be drained, ci- ther by letting off the Water, or drying it up by continual Fires, or by throwing dry Earth into them, none need doubt ; for in feveral Places and Countries there are fertile Fields, where there were formerly nothing but Bogs and Marfhes ; as in JVeflphalia, Gelderland, Brabant, Holland, Muf- covy, i^c. So xht Peloponnefus in Greece was, in the Time of the Trojans, barren and marlhy Ground, but was made fertile in AriJlotU^ Time by draining it. THE fame may be faid of Pools and Ponds, which are not very different. PR POSITION V. Rivers leave their Shores [or part of their Chancls) dry, and form new Parcels of Ground in many Places. I. I F their Water bring down a great deal of Earth, Sand, and Gravel out of the high Places, and leave it upon the low, in prccefs of Time thefe will become as high as the other, from whence 39^ ^he Abjhlute Fart Sect. V. whence the Water flows : Or when they leave this Filth in a certain Place on one fide of the Chand, it hems in and raifcs Pare of the Chanel v/hich be- con-^es dry Land. 2. IF a River take another Courfe, made by Art, or Nature, or fome violent Caufe, as the Wind, or an Inundation, it leaves it's former Chanel dry. 3. IF the Fountains that feed a River are ob- ftra6ted, or ceafe to fend out their Waters, be- caufe of the Earth falling in, or by being ftopped with Heaps of Sand driven in by the Wind from the adjacent Places, the Chanel of that River be- comes dry. EXAMPLES of Rivers, whofe Chanels arc now dried up either wholly or in Part, are frequent- ly met with among Authors; not of any great Rivers, but of thofe of the fmaller fort, and fome Branches of the great ones; thus that Branch of the Rhlne^ which formerly run by Leyden into the Ger- man Ocean, fome Ages ago foribok it's Chanel, which is now dry Land, and ftagnates between Leyden and Calwic. W E have alfo feveral Examples of Shores that have been left dry by Rivers making themfelves deeper and narrower Chanels than they ufed to run in i alfo of Rivers that are not navigable now, which have been fo formerly, their Chanels being made fhallower, and, in procefs of Time, maybe quite choaked up, as the Scbelde^ &c. Therefore the Rulers of Countries take care that the Sand- Blinks, Filth, and Sediment, be continually re- moved out of fuch Rivers, fo that diey may be kept open and navigable as much as poiTible. BUT great Rivers arc not dried up, or turn- ed into dry Land in a great many Ages, or even Myriads of Ages, bccaufe a vaft number of fmall ones Chap, i 8. of Unherfal Geography. 3 9^ ones flowing tiom diilerent Parts make up their Waters and feed them ; lb that if one or two of them be dried up, or change their Courfe, it will be a long time before luch an Accident happen to them all. One fingle Sand- Bank indeed might per- form Wonders, in choaking up the PafTage of a River, and make it take a new Chanel, whereby the former is dried up -, but the River itfelf con- tinues to flow, becaufe it's Fountains and Branches .are not obltrucfted. Neverthelefs it is certain, that neither the Nile, the Tanah^ the Elbe, nor tlie Rhine, &c. did or will always flow in the fame Places, but their Chanels were formerly dry Land, and in future Ages will be fo again. PROPOSJ'TION VI. Lakes are dried up and turned into Earth. I F the Lake be fed by Rivers flowing into it, the Change is made by turning the Rivers another Way, or by their ceafing to flow, together with Evaporation. If it receive it's Waters from the Ocean or Sea by fabterraneous Intercourfes, thefe are to be fl:opped or diverted ; and fo the Lake at firft is changed into a Fen or Bog, and after- Vv'ard into dry Ground. Arijlotle (fpeaking of Lakes fed by Riversj f\ys, it is certain that the Force of the Water bringing Mitd» or fuch like Matter, into any Lake, changes it into a Fen or Bog, and afterwards into dry Ground .; for the Water fl:agnating, is in Time dried up. Thus the Mud and Sand, which the many Rivers bring down into the Lake of the M^eotis, have made it fo ihallow, that it will not admit fuch large Ships now, as failed upon it about fixty Years ago. ^ Of 40 o "TJje Ahjhlute Fart Sect. V. Of finall Lakes that are turned into dry Land we have leveral Inllances, efpecially in Holland. PROPO S iriON VIL Streights are dried up and turned into IJihmus*s, or Parts of Continents. THIS is caufed by the contuiual gathering and fubfiding of the Mud and earthy Matter, which in Time choaks up the Streight, and ftops the In- tercourfe ot the Water. THUS it feems very probable that the Ifth- mus between Africa and Jfta^ which parts the Red'Sea from the Mediterranean^ was formerly a Streight and joined them. The Depth of the Sea in feveral Streights is alfo found to grow lefs, and the Water to become (hallower than it ufed to be, which is a certain Sign that fuch a Streight, fome Time or other, will be left bare, and be turned into dry Land. So that Bay in the Atlantic Sea which the Hollanders called the Zuidcr Sea^ and the Streiglits of the Texel, will not now admit of load- ed Ships of the firft or fecond Rate, as they ufed to do formerly ; and as the Water evidently leffens and becomes fhallower every Year, it is likely the Texel, will one Time or other, become dry Ground : and that Streight which they call Ulie will, very likely, have the n\me Fate. PROPOSITION vm. Bays may he in time dried up, and turned into firm Groufid. THIS may happen from a two-fold Caufe : i. If the Streights which join the Bay to the Ocean become an Ifthmus, or be choaked up with Sand and Chap. i8. of Unherfal Geography. 401 and Mud (that fuch a thing may happen, we fhew- cd in the laft Propofition^ 5 by this means the Bay is cut off from the Ocean, and becomes a Lake, which is turned into a Fen, or Bog, and then into dry Ground. 2. If the Chanel of the B.iy be heightened continually by the Sand and Grave), brought down by the Rivers into it, it will in Time be higher than the Ocean, and receive no more Sea- Water. THUS the MedlterranecVi^ Baltic^ Red-Sea, Perfian Gulph, ^c. which are now Bays, may bs changed, one Time or other, into dry Land i as we fhall further prove in the next Propofition. PROPOSiriON IX. The Ocean in fame Places forfakei the Shores^ fo that it becomes dry Land where it wai formerly Sea, THIS is caufed by thefe Means: i. If the force of the Waves dafhing againft the Shore, be broken by Cliffs, Shoals, or Rocks, fcattered here and there, under Water, the earthy Matter con- tained in the Water, as Slime, Mud, &c. is made to fubfide, and increafe the Height of the Sand- Banks, whereby the Violence of the Ocean is more and more refilled, which makes it yield more Se- diment ; fo that at length the Sand-Banks, being raifed to a great Height and Bulk, entirely ex- clude the Ocean and becomes dry Land. 2, It contributes much to heightning the Shores if they be (andy and rocky, for then the Sea dafhing a- gainft them, and withdrawing, carries little or no- thing away from them, but every Time it ap- proaches them it brings Dregs and Sediment, whereby they are increai'ed in the Manner afore- faid. 3. If fome neighbouring Shores confift of light, mouldring, porous. Earth, which is eafily V OL I. D d wallied 402 ' ■ The Abfolute Part S e c t. V. wafiied away by the Flux of the Sea, it is mixed with the Water, and left upon fome other adjacent Shore that is harder ; bcfides, when the Sea en- croaches upon one Shoie, it rclinquifhes another not tar oif. 4. Large Rivers bring down vaft Quantities of Sand and Gravel to their Moutlis, (where they exonerate themfelves into the Sea) and leave it there, partly becaufe the Chanel is wider and fhallower, and partly becaufe the ^ea refills their motion ; but this is chiefly obferved in Countries, whofe Rivers annually overflow their Banks. 5. If frequent winds blow from the Sea to the Shore- wards, and the Shore itfelf be rocky or of rough Earth without Sand, it gathers Slime and Mud, and becomes higher. 6. It the Tide flow quick, and without great Force, but ebb flowly, it brings a great deal of Matter to the Shore, but carries none away. 7. If the Shore de- fcend obliquely into the Sea for a great Way, the Force of the Waves are broke and lefTened by Degrees, and the Sea leaves it's Filth and Slime upon it. THERE are feveral Places of the Earth, which, it is certain were formerly covered by the Ocean. Wiiere Egypt is now, it was formerly Sea, as ap- pears both from the Teftimony of the Antients, and Experience ^ tor the AV/c, flowing from the remote Regions of ELhiopia, when it over- flows it's Banks, covers all Egsjl for a Time, and then fettling by Degrees, it leaves the Dregs, Mud, Dirt, and earthy Matter, which the fwilt Courfe of the River had brought down •, by this means Eg'spt becomes annually higher and higher. But before fuch a Quantity of Matter was brought down to the A7/i?, the Sea covered the Land of Egvpt, tho' it be repulfed and hemmed in now by the Earth's ac quired Altitude. Arifiotle^ among others, aflferts this, and fays : This Place, and the whole Coun- 3 try C H A p. 1 8. of JJniverfal Geography. 403 try fmeaning Egsipt) were formed by the pouring in of the ISile, and feems to gain Firmncls every Year. But fince the neighbouring Inhabitants, by Degrees, began to culcivate the Marfnes and Bogs as they dried up, it is impoffibk to gucfs at die Time of this Mutation. However, it feems that all the Mouths of the Nile have been made by Hand, and not by the River, except that of Ca^ nopus. It is tiirther evident, that all old Eg'^pt confifted only of one Town, which they called 'Thebes. Homer dechrcs this, who flouriflied (I may lay) not long after thefe Changes ; for he men- tions that Place as if there were then no flich City as Memphii^ at leaft not fo large. Seneca explains this better thus: Eg^pt (fays he) arofe wholly at firft from Mud •, and if we may credit Homer ^ the Ifland of Pharos was fo far diliant from the Con- tinent, as a Ship, with all her Sails fpread, could fail in a Day, but now it is joined to the Continent; for the Nile flowing muddy and troubled, and car- rying dov/n much Slime and Dirt, leaves it about it's Mouths, whereby the Continent is annually en- larged, and Egypt is flretched further and further every Year. Hence comes the Fatnefs and Ferti- lity of the Soil, and alio it's Evennefs and So- lidity ; for the Mud fettles and grows dry and hard, and the Ground becomes firm by what is laid upon it. THE Ganges and hidus^ both famous P^ivers in Ifididy do the fame as the Nile, by their Inunda- tion ; alfo the Rio de la Plata in Brajil. And it is very probable that China v/as formed by this means, or at leaft enlarged •, bccaufe the impetuous River, called the Hoamho^ flowing cue of Tartar^ into China^ and frequently overflowing it^s Banks, tho' not annually j hath fo much Sand and Gravel in it, as to make a third Fart of it's Waters. Dd 2 THESE 404 The Ahfolute Tart S e c t. V. THESE Examples demonftrate the fourth Caule, viz. that Rivers make the Sea toriake the Shore •, but the Sea it fell, in leveral Countries, is the Caufe of it's own retiring, by bringing to the Shore, and there leaving Sediment and Matter enough to increafe the Altitude of the Coaft \ fo that it fullers not the Sea to overflow it any longer. Thus Holland^ Zeeland.^ and G elder Ian d^ were formed -, for the Sea covered thefe Countries formerly, as is known both from the antient Monuments mention- ed in Pliftory, and the Quality of the Soil itfelf. In the Mountains of Gelderlandy not far from Ni- meguen, there are found Sea- Shells, and at a great Depth in Holland are dug up Shrubs and ouzy mat- ter i add to this, that the Sea itfelf is higher than thefe Countries, and would overflow and cover them, but that it is reftrained by Banks and Dams. On the other hand, there are fome that think Hol- land and Zeeland arofe from the Mud and Sand brought down by the Rhine d.nd the Maes\ nor is this unlikely. PruJJia alfo and the adjacent Countries daily become larger by the Sea's retiring. P RO P O S iriON X. To explain the Origin or Rife of Sand- Banks. B Y Sand-Banks we underftand large Colledions or Cliffs of Sand in the Water, (landing up above the Chanel of a River, to fuch a Height as to hin- der the PafHige of Ships. The Dutch Sailors call them een Droogte, een Banck, een Rifs ; the Portuguefe^ j^brothes, and Baixes. They differnot from Rocks, only that Rocks are hard, folid, and coherent in their parts ; whereas Sand-Banks confiftof grains of Sand, that ftick more loofely together. The* thefe two are often confounded. THESE Chap. 1 8. of Vniverfal Geography. 405 THESE Sand Banks Jie either in the Chantls of Rivers, as frequently in the Eihe^ ainl the IVol^a j or at the Mouths of Rivers, as is alfo frequent in the two Rivers juft mentioned; or on the Sea Shores, or in the middle of the Sea. The manner of their Generation is the fame as in the foregoing Propofitions we obferved of the drying up the Courfe of Rivers, and the Shores of the Sea. For it generally happens, that the Ocean, before it leaves any part of the Land for good, firfl pro- duces thefe Sand- Banks near the Shore ; then recedes by degrees, and leaves the Sand- Banks a part of the Continent. And after the fime manner it hap- pens in the Chanels of Rivers, before they dry up, and are totally forfaken by the Waters. The moll common Caufe is the increafing of the Rivers with Rain, or melted Snow, fb that they rufh down violently, and wafh off their Banks, where they are narrow, Slime and Mud •, which is carried down a great way from their Fountains, till 'tis brought to fome wide Place, where the Motion is not lb violent ; and here it fubfides and forms a Bank of Sand, or Mud. NOR can any greater Evil happen to the moft rich and flourifhing trading Towns, whofe loaded Ships have been ruined by them •, not to mention Towns, that thro' Time are quite forgot, there are the Cities Slavorcn in Frief.and \ Arncmudc, or ^r~ mugen^ m Zedand \ and Dordracu??i in Holland » Antwerp in Brabant ; and Slada^ in the Bifnopric of Bremen •, all which have had this. Fate. NOR is there fcarce any trading Sea-Port free from the Danger. Thefe Sand- Banks in th.c Elbe^ have loft a great many Ships to the Hamhurghcrs^ which had efcaped many Dangers on the Ocean i and in other Places, efpecially the Tcsel^ and the Ulie at A?njlerda?n.

W E have fhown one Way how they are formed, viz, by the fubfiding of the Matter which the Sea carries with it •, we may add a fecond Way, and that is, by the Sea's coming in upon Land, that hath heaps of Sand on it, which, being covered, are Sand-Banks under the Surf^e of the Water, Thus at the Shores of Gelderland, and Holland, there are feveral fuch, which they call Dunen ; they are in a Jong Tradt raifed above the Land, on the Shore ; Chap. i8. ofUfiiverfalGeograpbw ^^oy Shore -, and if the Sea break in, then thefe. Hills become Sand Banks. T H E Y are frequently at the Mouths of Rivers where they are broadert, and where their Motion is not fo rapid but the Matter can fubfide, and the Waves of the Sea beat back the River-Water, which ftops it's Force. It is worth while to dillii.- guifli and confidcr thefe two ways. PROPOSITION XI. ' To judge "^belter the Sand-Bank^ uot far from the i>bore will become a ■part of the Continent. W E fhowed, in the preceding Propofition, that they are formed two ways •, one by the fabfiding <;!■ Matter, and the other by Heaps of Sand that are overflowed: if they happen in the firll: way, and they be found to incrcale (till, it is likely thty will be joined to the Continent •, but if in the fecor.d way, and they are not increafed, then it is not like- ly they will be joined, but rather that the Sea v/ill come further : but this we only guefs, PROPOSITION XII. IJIands are formed in the Sea and Rivers^ the fame wax that Sand-Bankiare['ivhiJj may become JjJandi)^ and alfo another way, FOR if there be gathered in any part of ti-.e' Sea, Sand, Gravel, Slime, or Clay, it will in time t become an Ifland ; and if the Sea break in upon the Land, and furround Hills, they become lilands ; and thus 'tis likely thofe were formed which are very high, as St Helena, the I fie of Afcenf:on^ l^c, efpecially if they be rocky and fiony. D d 4 AND 4o8 Tie Ahjoliite Part S e c T. V. A N D to thele belong thofe which the Sea cuts off from the Land that juts out into it ■, thus antient Writers tell us, that ^icii^ was cut off from //rt/)', by the breaking in of the Sea violently ; and the Verfes of the Poet on this Subjed are well known, B Y the firft way, viz. by fubfiding and ga- thering of a great many earthy Particles, were formed the Iflands of Zeeland^ Denmark^ and Ja^ fan't and alio the Ifles of Molucca: for there were found, by thofe that dug the Ground there a little way down, a great quantity of 'Sand and Snells. THE Inhabitants of the Ifland of Ceylon fay their Ifland was fcpaiatcd from India, and it is ve- ry likely. Thus the Ifland of Sujnatra is thought to have joined Milacca -, and it is probable, becaufe of the feveral Banks and Qiiick-Sands there. It is certainly believed it was the golden Chcrfonefus^ and was counted to be a Peninfula, for it appears fo at a diftance, and to be joined to Malacca. THE Indians, on the Alalabar Shore, tell us, that the Ifles of Maldives ^ were of old joined to India, in one Continent, and are now a great way from it, and divided into eleven thoufand Iflands i and it is probable they will all in time be joined in one Ifland, they being not diflant in fomc Places above four or five Yards. The narrow Seas will become narrower, and fo join one to another. And indeed all the oriental Iflands, between the Continent of Afia and Magellan, feem to arife from the Sea's breaking in violently on the Land, and feparating one part from another ; for the Pacific Sea moves v/ith a continual force to the Eajl from America to thefe Ifles, and the 'Wind blowing conftantly that way increafes the force ; it is not therefore unlikely that, feeing all thefe Iflands are in the Torrid ZonCy Jfia did of old Chap. i8. of Vniverfal Geography. 409 old join the Magellanic^ or South Land, the Earth being broke olf here and tlicre by the Sea, 'till at latt it made it's way to the Indian Ocean, and formed many Iflands ftrangely fituated dole toge^ ther, as Java^ the Celebes, Borneo, Madura, Atn- boyna, i^c. W E may judge the fame of the Iflands in the Gulf of Mexico, and at the Streight of Magellan. I T is uncertain whether the Iflands of the jEgean Sea were broke off the Land by the Sea, the Waves from the Euxine and Mediterranean Sea meeting one another, or by the fubfiding of the Matter which v/as brought from the Euxine to the Propontis \ tho' the former is more probable : and perhaps this was the lamous Deluge of Deucalion. It is certain the Ifle of Eubaa, or Negroponte, joined Greece, as famous Writers relate ; for the Sea be- tween them is fo narrow as to have a Bridge over it. V\^ E have feveral Inftances of Iflands made by- Sand- Banks. Thus thofe in the Nile, and in the 'R.'xwtx oi St Lawrence in North America, were Sand- Banks. The Rivers make Iflands alfo when they difcharge a Branch in one Place, and receive ic in another, as in the Tanais, and JVolga, and o- thers ; which no doubt is done by the Induftry of Men. The Oby does the fame. The two Rivers, Rengo and Coauza, produced the Ifle of Loanda, on the Shore of fouthern Africa, where they exonerate themfelves into the Sea, be- caufe they bring down from the high Places a great quantity of Slime and Gravel with great Vio- lence, which they depofited fl:ill in the Mouths of the Rivers, and fo made the Ifle of Loanda ; which at firfl: was but a Sand- Bank, and now it is a fruitful Ifland, abounding with Inhabitants and fertile Land. We believe a great many Iflands on the Shore were formerly Sand-Banks, or Clay-Bnnks, tho' fome 4IO ^he Abjblute Part Sect. V. fome were made by parting them from the Con- tinent, as at Norzuay : and this is moll probable oi" thofc that are hard and rocky. B U l\ in the hidian St-a, luch may happen by both ways •, for while the Sea wears olt, it doth at the fame time carry away with it much Earth, which fettles in another Place i and this is much caufed by iurious Winds, and frequent Storms, that come from the breaking of the Clouds in the rainy Months ; from Aldy to September. The Sea is flrangely difturbed by thefe, fo that the Sand and Clay is railed from the bottom, and carried to the Indian Shores. Thus the Mouths of the Harbours at Goa are fo obftruded by Heaps of Sand, which come with tlie force of the Storms from May to September^ that fmall Ships can fcircely enter •, and thefe Heaps of Sand fo cbftrucl the Harbour of Cochin^ that they are like a Bar, or Wall, that neither great nor fmall Ships can enter. FOR continual Rains on Mount Gate^ and the frequent Storms from the Clouds which are ktw hanging as it were above the tops of the Moun- tains, pour out fo much Water with fuch Violence that the Sea carries a great deal of Sand to the Shores ; where, meeting with Oppofition, the Sand fubfides, which is carried away again by the Sea, when the Winter is over, and the Harbours cleared. THERE are fome Iflands fo near the Land, that they are furrounded at the time of full Sea ; and if the intervening Chanel become higher, thefe Iflands become a Part of the Continent. AND the overflowing of the Nik makes the Towns and Hills look like Iflands; and the JVolga doth fo fwcll in May and June as to cover the Iflands and Sand-Banks in it •, and feveral of the IQands near India become like Sand- Banks in the rainy Chap, i 8 . of Unherfal Geography. 4 1 1 rainy Months, when the Nile and Ganges overflow theie Countries. PROPOSITION XIII. There is ancther way that Iflands are formed hcfides the two abovementionedy which is delivered by fome IVriters^ viz. that the Earth on a fudden is car- ried from the bottom of the Sea, and fuddenly rifes to the Surface. OTHERS think very juftly that this fabulous way comes from the fabulous Greeks and Poets, who will have Delos to have come up that way ; and the grave Author Seneca fays, the Ifland Therafia did, in his Time, come up in the jEgean Sea, and that the Seamen obferved it : and tho' indeed there are but few Examples of this kind, yet we are not therefore to think it impofTible ; for there may be in the bottom of the Sea fome porous, fpongy, hollow, and fulphureous, Earth, (as there are many forts of light Earth,) which is now grown to a great Height under the Water ; and if it come to break off by the force of the Sea, and being of lefs or equal Weight with the Water, it may come to the Superficies, and an Ifland appear on a fudden. Or a Spirit fliut up under the Earth, and endea- vouring to break out, may without the force of the Water bring it up to the Surface ; for thefe Spirits included have great Power, as appears in Earth- quakes, by which whole Mountains have been thrown up and fwallowed down, and the fame way are great Towers and Walls blown up by Gun- Powder placed under Ground. I F therefoKe the Ifland that thus appears fud- denly do yet adhere to the Bottom, it mufl: be that it was forced up by the Spirits inclofed un- derneath ; as fome write, that fometimes Moun- tains 412 TJje Abfolute Fart Sect. V. tains have been blown up that way ; but if it do not adhere to the Bottom, it might be loofened from the Bottom, partly by the torce of the Wa- ter, and partly by the inclofed Spirits, and come up by it's own Lightnefs. PROPOSITION XIV. FROM this another doubt ari fes •, Whether there are floating Iflands ; as Thales thought the whole Earth did float on the Water of the Ocean : but his Opinion is fufficiently refuted from the Sea's Chanel being continued every where, and yet there may be floating Iflands if the Earth be hollow, light, and fulphureous. Sefieca tells his Experience, that he faw in the Lake Cutilia, m the Fields of the Town Reate, belonging to the Sabwes, an Ifland that floated, and Trees and Herbs on it, that was carried here and there by the Wind, yea by a gentle Gale -, and that he never found it for a Day and Night in the fame Place ; and he lays there was another Ifland that floated in the Lake of Vadimone •, and another in {tiQ.h.dke, oi Statione. Thus the Antients fay, that Delos, and all the Iflands of the Cy chides^ did of old float on the Sea. Nor need it be objeded, why don't they fwim now ? for the Anfwer is eafy ; the floating cannot hold out long, for they reach- ing near the Bottom, and being carried from one place to another, they meet with a Sand Bank and and fettle there, efpecially if they come between two Sand-Banks, then they join and become fixed. In Honduras^ a Province of jlmerica^ there is a Lake in which there are feveral little Hills, planted with Shrubs and Herbs toffed up and down with the Wind. I N the large hoch^ called Lomond in Scotland^ there is an Ifland that floats, and is driven by the Chap, i 8 . of Vtiiverjal Geography. 413 the Wind: it feeds Cattle, as Boi'lbiasy the Wri- ter of the Scots Hillory, relates. SO far of the forming of dry Land where Sea was -, now we fliall confidcr how there can Water come where there was dry Land. PROPOSITION XV. 'Tbe Rivers run in new Chaneh for feveral Caufes, 1.

There is Ocean ivhere there was none before. THIS may happen feveral ways ; i . When it breaks into the Land, making Bays and Streights, as the Mediterranean^ the Bay of Bengal^ the A- ■rabian Gulph, and Bay of Camboia^ (^c. Thus the Streights between Sicily and Italy, between Ceylon and India, between Greece and Negroponte, the Streights of Magellan, Manilba, and at the Sound ', yea fome will have the Atlantic Ocean thus made, and to have parted America from Europe, that they may better deduce the Genera- tions of Men there from Adam. It is certain the Egyptian Pried told Solon, the Athenian, that about fix hundred Years before Chrift (as may be ken in Plato's Dialogue called Timceus) that there was once an Ifland over againft the Herculean Streights of Chap. 1 8. of Univerfal Geography. 41^ o\ Gibr alter, greater tlr^n yl/ric a -And y^fi a, called /Itlcuilii, and by a great Earthquake and Inun- dation in a Day and Night, that it was after- ward funk fx'iz. a Part of if j; by which wc may underftand there was a Tradition among the Egyj>j. tiaris, who were given to Learning, that America. was feparated from the old World, many Ages before.

WHEN the Sea is driven on the Shore with ftrong Winds breaking down the Shores and Banks, made by Art or Nature ; there are feveral Inflanccs of Inundations, as in T'heffal-^ of old, and not long ago in Friejland and Holjtein. 3. WHEN it doth, by the Hime Caufcs, go over the Land in feveral Places making Iflands ; as we iliid of thofe in the £^7? Indies, and the Bay of Bengal and Camboia, which flowed into the Land. 4. W H E N it wears off the Shores, and fpreads in upon the Land : thus the Bailie Ocean came in upon Pomerania, and deftroyed Vineta, a moft famous Sea- Port. Thus on the Shore of Nor-waj it broke in, and cut off fome Iflands from the Continent, and the German Ocean broke in on Holland, near the Village of the Catti, and over- fpread a great Tra6t of Ground ; thus the Ruir,s of an old Brili/Jj Caftle, that was a Garrifon of the Romans, is, a great way in the Sea, hid un- der Water, And on the North part of Ceylon near India, the Sea took off twenty Miles, and made tlie Iflaixi Icfs j and there are many other Examples alfo.

'D' PROPOSITION XVIIL Whether the whole Surface of this Globe may be either all Land or Sea ; or if there may be more Land or Water one time than another. I T is fufficiently fliown in the fecond Propofition, that there may be lefs Earth, and confequently more Sea, one time than another. But to that Queftion, whether there may be a Deluge that fliall cover the whole, even the very Iflands •, we an- fvver the way how fuch a thing may happen, may be conceived and explained, yet can fcarce ever happen, the Earth being fo compa6tly joined and the Moun- tains fo high. The way it may happen is the fame as in the fecond Propofition. If the Ocean continually wafli away the Shores and lay them in deep Places, at lad all the high Parts will come down and be waflied away, and the Sea come in on the whole Earth , there may bs fome Mountains or their Roots wafliied Chap. i8. of XJniverfal Geography. 417 wafhed away, and they fall down -, ind it Were eafier done if, as fome think, the Sea were higher than the Land, bur this we have before refuted. And to that, whether the Sea can ever go all into Caverns of the Earth, and there be nothing but dry Land, we anfwef the fame way ; the' it may fcarce ever be : there is only one way by fuppofmg the Caverns fo large as to contain the Sea, and none have yet demonftrated the contrary \ and tho' they are not, they may be made fo by the force of the Water or fubterraneous Spirits. PROPOSITION XIX. PFhy there are few IJlands in the middle of the Ocean, and no Clujlers of them^ except at large JjJauds, or near the Continent. WE need not doubt of the Truth of this, being confirmed by Experience. There is fcarce one little Idand in the middle of the Pacific Ocean, and there are but few found in the vaft Ocean be- tween Africa and Brafil^ except St Helen and the Ifle of Afcenfion ; but on the Shores of the Ocean j or great Continent, are all the IQands, except the few I mentioned, efpecially the Cluftersof Iflands ; thofe of the jEgean Sea are near Europe and Afia^ the Hefperides near Africa, the Maldvies near India^ and all the Indian Iflands lie between Afta and the South Land, only the Azores^ or Flandrian Illes, feem to be in the middle of the Ocean, be- tween America and the Old World j the' they are nearer the latter. THE Caufe of this Phsenomenon no doubt is, that they were cut off the main Land by the Sea's breaking in upon it, which could not cover all Places it came to, bccaufe of their Height.

There are fometi?nes more^ fomedmes feiver Exhala- ihnsfent up ; efpecially in different Places. THE Ciufe is, i. The difi'crent Elevation or Deprefiion of the Sun above or below the Horizon. 2. The difierent Age of the Moon, and it's Eleva- tion above the Horizon. 3. The rifing and letting of the other Stars, and their Situation above the Horizon. 4. The Difference in the Parts of the Earth ; for Water and moift Places fend out more Vapours than dry and earthy. PROPOSITION IV. The Exhalations that compofe the Atmofphere are ct the Earth and the utmoil bounds and extent of the At- mofphere it is every where of the fame Denfity; juft as Wa- ter, which, howfoever deep, is every where from top to bot- tom equiilly dcnfe ; now fince from what has been already fa id, it appears, that the Weight of a Column of Air, reaching to the top of the Atmofphere, is equal to the Weight of Mercury contained in a Barometer ; and feeing al- fo the Proportion of Weight be- twixt equal quantities of Mer« cury and Air is fotmd ; it were eafy to give a Defini- tion of the Altitude of that Co- lumn of Air, or of the whole Atmofphere. For fcdng a Co. lumn 428 ^je Ahfohtc Fart S e c T. V I. fured the Heat or Cold in the Air, for the colder the Air in the Glafs, it takes up lefs Room, and the lumn of Air one Inch high, is to the like Column of Mercu- ry, as I to loSoo, it appears that thefe 10800 Columns, or a Column of Air 900 Foot high, is equal in Weight to i Inch of the Mercury, and con- fequently that all tlie 30 Inches of Mercury, contained in the Barometer, require a Column of Air 2-000 Foot high. So that, according to this Hypothefis, the Altitude of the Atmofphere would be only 27000 Foot, or a little more tiun 5 Miles. But when, in the high Re- gions, the Air, by it's elaftic Force, refiles and expands it- felf, according as the Weight of the incumbent Atmofphere is diminillied, it muft of necef- fity be far more rarified and fubtile than the Air near the Surface of the Earth: and con- fequently a much greater Alti- tude muft be afligned to the Atmofphere, than what was found b)' the juft now mention- ed Computation. For feeing, according to the Theorem above laid down, the Spaces in which the Air is included, are reciprocally pro- portional to the compreffing Gravities ; but the denfity of e- very Body is in a reciprocal Ra- tio to the Spaces, which that Body poflefit;s ; the Dcnfity therefore of the Air in any Part of the Atmofphere will be proportional to the Weight of the whole incumbent Air. And furUierj if we fuppofe the Al- titude of the whole Atmo- fphere divided into innume- rable equal Parts, feeing the Denfity of Air included in a- ny one of thefe Parts is in proportion to it's quantity, and the Weight of the Atmofphere is alfo as the quantity of the whole incumbent Air ; it ap- pears, that the quantity of the whole incumbent Air is every where, as the quantity of Air included in the lower Part, which conftitutes a Difference between every two neareft quantities of the whole incum- bent Air. It is a Theorem in Geometr)' ; that fuch Magni- tudes whofe Di. Terences are proportional to the Magnitudes thcmfelves, thefe Magnitudes are in a continued geometrical Proportion. Whence if, ac- cording to the Hypothefis, the Altitude of the Air, by adding the equal Parts, into which it is divided, increafe in a continued arithmetical Proportion, it's Denfity will be diminifhed, or, which is the fame, the Rare- fadlion of the Air will be in- creafed in a continued geome- trical Proportion. Such as know the way of following fuch a Series, by taking a View of one or more of the Rarefadi- ons of the Air at different Alti- tudes, rnay, without any Trou- ble, determine it's Rarefaftion in any Altitude, or the Alti- tude anfwering to any Rarefafti- on, and fo alio the Altitude of the whole Atmofphere, if it may be Chap. 19. of Unherjal Geography. 429 the more Room, the more Heat it acquires ; as we Ihall fhow in the following Propofition. The natural be known, or made the e.v- tieam Degree of Rarcfadion, beyond which the Air cannot pafs. Such as incline to know more on this Subjeft, may confult the famous Dr Gre- go>y\ Aftronomy, Lih. v. Prop. 3. as alfo the excellent Dr Halleyi DiiTertation in Ph'ilo- fophical Trarfadions N° l8l. who have demonllrated the fame in a different, and fome- what more difficult way of reafoning, which I have here borrowed from the Demon- firations of a very learned Friend, But withal we muft not conceal, that thefe things have been rendered uncertain by the Obfervatioos of the famous CaJJlni * and his Affiftants ; who, in order to extend the Meridian Line of the Par'n Obfervatory, after having with great exaftnefs meafured the Altitudes of feveral Mountains, and marked the Height of the Barometer on the Top of each of them, they found that the Rarefadlions difcovered by that Method, no ways agreed with thofe we have lately hiid down, but that they were far greater than what ought to come out from the abovtmentioned Pro- portion : whence becoming fuf- picious, that the Experiments they had formerly made for £nding out the Rarefadion of * Illjl. deTAcad. %. 1 703, and 1 705. the Air under different pref- lures, had not been man;igcd with fufficient Accuracy, tluy determined again to put the Matter upon 'fryal, which Sub- jeft being diligently treated of in the Royal Academy, and when there were made great Dilatations of Air, compared to which, the Rarefa(flions found on the Tops of Mountains, were woundrous fmall ; yet they found that all theie exaftly followed the reciprocal Ratio of their incumbent Gravities. So that it feems to be put beyond all doubt, that fuch is the Nature of the Air, which comes neareJi to the Earth's Surface, that the Icfs preiTure it has upon it, the greater Space it dilates itfelf into : and feeing the upper Air, or fuch as environs the Tops of Alountains, does not obferve this Propor- tion, it follows, that it is of a different Nature from the Air , that is next us, which notwith- flanding needs be no caufe of wonder to us, if, according to the moft approved Senti- ments of Philofophers, we al- low that there is in our At- mofphere, bendes Vapours and terreftrial Exhalations, a certain Body of kin to itfelf, and en- dowed with fuch AffeClions, as we have above affigned to the Air; and further, that thefe Vapours and Exhalations, are no ways capable of fo great Rarefadion, as is the Air ; and that thefe are mixed in far greater 430 1'he Abjolute Part Sect. VI. natural Caufe of the Propofition is this •, that the hot Particles of the Sun's Rays^ or any Fire, are *-■..'-.= the greater plenty with the Air neareft us, than in the upper Air. Thefe things being laid down, it is nianifeft that the Air of the higher Countries be- ing lefs ftored wid- \'apours, has, in proportion to it's Denfi- ty,moreEIallicity in it than that which comes next to the E::r:h, whence the reciprocal Ratio of Gravity, which is in the Air next the Earth, does not hold here ; and further, that \'«- pours and Exhalations have not fuch Elaftitity as Air, but that this is much more rarihed arid extenuated. But the excellent Mr Fontenelk, Secretary of the Society, explains thefe Phrenomena in a quite diffe- rent Manner, in his Hiftory of the Academy, Anno 1708. He propofes fome Experi- ments performed by the famous Mr De la Hire, and others, from which he infers, that the elaftic Force of the Air is in- creafed wlien it is mixed with Moifture, or when compound- ed of Air and aqueous Vapours, the Rarefiiftion will be greater, than from pure Air; and that therefore on the Tops of Moun- tains the Air is found more rarified, bccaufe many Vapours are carried thither for produ- cing of Rain. The Experiments are thefe : They took a flender glafs Si- phon, one of whofc Legs end- ed in a large hollow Sphere, be- ing open at the other. Thij Siphon was full of common Air, and expofed to the external Air coming into the Siphon. The Globe and Siphon was plunged into hot Water, found by pre- vious Experiments to be of the fame degree of Heat as boiling Water, and confcquently cau- fmg the fame degree of Rare- faflion ; tho' the Fire under- neath were'greater or lefs. When the Air included in the Globe was rarefied with this degree of Heat, it would be gradually thr'uft out at the other end of the Siphon ; 'till at length the Globe being heat- ed to the utmoft, there was left a very fmall quantity of Air, highly rarefied, that poffefled the whole Cavity. Then the Water being removed from the Fire, the Air, as it gradually cooled, which before poflelTed the whole Globe, being gra- dually contracted by the Cold, gave way to the Water that entered at the Orifice of the external Leg, and at length, when the Water became entire- ly cold, it was contraded into a very fmall Space, whilft the rell of the Globe remained filled witli Water. Now by comparing the Space, poflefTed by the Air, cooled and redu- ced to it's natural State, and the whole Cavity of the Globe which it had at the utmofl; Heat, it appears how much the Air was rarefied with that de- gree of Heat. This Chap. 19. of U/iherfal Geography, 43 i . the mod iubtile in the World, and inconftanf Motion, and wjiile thefe are mixed with the At- ijv b,/x..; molphere. This Experiment was firft made in clear Weather, again in a moift: and rainy Scafon ; and at a third time, a little Water was left adhering to the inner Surface of the Globe. And it was obferved that the Air con- denfed at the end of the Ex- perinaent, in the firft Cafe pof- fefled f of the Globe, in the fecond poflefled but z,, and in the third j'^ \. Whence Mr Fontenelle concludes, that the Air was more dilated in the fecond Cafe, but particularly in the third, than in the firft Cafe; and therefore as the Air is the more dilated the more moift Vapour is mixed with it; hence he concludes it probable, that for the fame Reafon, there is a greater Rarefadionon the Tops of Mountains, becaufe the Air that furrounds them is mi.ted with a greater quantity of A'a- pour. But there are two Con- fideratlons that render the Ar- gument inconclufive. For firft in the two later Experiments, as aqueous \''apours were-plerp tifully mixed with the Air, it might happen that when the Air was condenfed, and the Water entered thro' the Siphon into the Globe, thefe Vapours might again return to Water, and mixing with the other Wa- ter partly by the Force of Con- denfation, and partly by the mutual Attraction there is be- twixt the Particles of Liquors, leave but little true Air inclu- ded in the very fmall Space, Whence It might fcem, that the quantity of Air which rarefied with the fame degree of Heat poftefled the whole Cavity, was lels in the two latter, than in the former Cafe ; and therefore more dilated, fo as to poftefs i the whole Space. ' Again, allowing that the i Air was more rarefied in the latter Cafes, yet as this was ef- . feifled by the means of Heat, ' I do not fee how it follows that becaufe the Vapours mixed with the Air, and agitated by Heat, are more rarefied thaa Air without Vapours, therefora thefe Vapours without Heat, fhould have a greater Elafticity than pure Air. We iliall here add a Table of AI.

(r) Mr Haukjhee, in his Phy- Jko - Mechanical Experiments, pag. 218. has, by avery curious Experiment, determined the Ratio of the Places pofleffed by the Air according as it is differently heated. ABC [Fig. 2!^.) is a refian- gular Glafs Tube, B a little Column of Quickfdver : A the extremity of the Tube, cemen- ted to a Screw, fitted with a Cap, and fhut after the fettling of the Quickfilver, the Space A B is full of common Air, included betwixt the Screw and the Quickfilver ; whilll the part of the Tube B C, is open to the external Air. This Tube Mr Haitkjhee placed in a pro- per VefTel, along with a Ther- mometer, then pouring in hot Water enough to cover the Ball of the Thermometer, the Quickfilver B moved from or approached towards A, accord- ing as the Air AB was more or lefs contradled by the De- grees of Heat. And by means of thefe Obferv-ations he made the following 1 able ; wherein the Degrees are the fame with thofc marked on the Thermo- meter for meafuring the afcent of the Liquor ; being the inter- mediate Degrees betwixt the greatell Heat, and the greatefl Cold of our Climate. The Column of Parts fhews the Pro- portion of the Spaces wherein the fame Bulk of Air is includ- ed according to the Degree of Heat annexed ; where it is to be obferved, that the Air con- llantly and uniformly lofes one 144th part of the Space it oc- cupies in the greateft Heat, every twelve Degrees that the Thermometer fmks.

PROPOSITION IX. To make a Thermometer^ &r Thermofcope^ by which we may try the Changes in the Air, as to Heat and Cold. LET us take a Glafs with a long round Neck and round Body LH {Fig. 26.), let it be faftened to a Board M N P Q, with it's Neck downward, and let there be a Yeflel fo filled with coloured Water, put under it, that the Part of the Neck L F may be under the Water, and chufe a Day of a middle Conftitution between Heat and Cold, with which the Heat and Cold at other times may be compared ; and let the Water be poured into the Veffel at that time, when the Air growing cold the Water will afcend above F of it's own accord ; for the Air that before filled the Space F A being condenfed by the Cold takes up lefs Space. On the other hand, the Air being made more hot, the Water will come down from F towards L ; for the Air F H being rarified takes up more Space. AND the Degrees of increafe and decreafe of Heat and Cold may be known, if you divide the Line F A into a certain Number of Parts. O R without a Veflel underneath, let the Glafs L H have, at the end L, a hollow Ball of Glafs, with a fmall Hole on one Side, filled with Water, F f 3 and 43 8 "Hoe Ahfohite Tart S e c T.

THIS is proved from the Molipile^ which if it be taken when white with Heat, it will then receive thirteen Ounces of Water i but the fame jEolipile when cold, or in it's natural State, will take thirteen and half a Dram, and that Part which contains the half Dram is the Difference of the two Spaces, and is almoft the feventieth Part of the whole Cavity of the yEolipile. {s) This kind of Thermome- ter was thought to fhew the Heat or Coldnefs of the Air, with fufficient Accuracy before the dilcovery of the Barome- ter. But after it was found that the Air was not of one conftant Weight, but differed at different Times, it was re- marked, that the Water in- cluded in the Glafs Neck, ac- cording as the Weight of the Airincreafedordiminifhed, and reeking upon the V/ater con- tained in the Veffel, muft alfo afcend or defcend tho' the De- gree of Heat fhould remain the feme.

Why in Places of the Frigid Zone, when they have not the Sun rifing and fetting^ the Air is fo?ne Days clear ^ but grofs and cloudy Jor the mojl part. T HE Caufe of that thick Cloudinefs, which is almoil conftant, is, the fmall Heat of the fubterra- neous Earth, or that comes from the Sun, or Moon, (which remains for feveral Days and Nights above the Horizon whilft the Sun is below, ) and other Stars i which Heat, being weak, is not able todif- pel the Cloud ; and fome Days being clear, is i.ot from the grofs Vapours being made fmall, but from their falling down on the Earth, or being driven away by the Wind. PROPOSITION XII. JVhy fometimes in the greateft Cold in Winter the Air is fubtile and clear ; whereas Cold condenfes and contrails the Air. COLD is twofold, moderate and exceflive : a moderate Cold does not make the Air clear but cloudy, for by the fmall Heat that is joined with the Cold, the Vapours are raifed but not difpel- led ; but a vehement exceflive Cold renders the Air clear, for two Reafons ; i. It makes the grofs Vapours in the Air more grofs -, and fo they fall down, and the Air is thus cleared. 2. Becaufe the Pores of the Earth are fhut up, and the Va- pours are not exhaled from it, that render the Air turbid and cloudy. The Sea indeed is not frozen with Cold i yet it's Particles are made fo thick with Cold, that it doth not fo readily fend out Exhalations, tho' it doth a great many, being of another Nature than the Earth, Ff4 PRO- 44^ ^he Abjolufe Fart Sect.

THE Caufe is twofold ; the firft becaufe the Air near the Horizon is really more cloudy ; tlie other is a deceit in our Sight ; for the Eye takes in the Diftances of the Parts of an Arch in the Hori- zon, by very fmall Angles -, as it does the Diftances of Pillars in a long Row : and as we judge thofe that are diftant to be near, fo the diftant Particles of Air are judged to be joined clofe ; but the Diftance of the Particles of Air that is higher, the Eye kts under great Angles and apprehends them the better, THE fame is the Caufe why the Air at a Diftance appears to be cloudy ; but when we ap- proach to it, it does not feem fo cloudy. TROTOSIflON XIV. Whether the Atmofphere or Air be alwap of the fame Height in all Places -, cr if it's Figure be fpherical. T H AT it is not of the fame but of very dif- ferent Heights, appears in that the Sun is only vertical to one Place at once, and fends it's Rays obliquely to other Places ; and fo more weakly the more they are remote from the Sun, or the nearer the Poles : and therefore the power of the Sun is different in different Places, and muft raife the Vapours differently •, they are higheft diredtly under the Sun, and loweft in the oppofite Point, i^nd in a middle Height at tlij^ Pole, fo that the Air is of an oval Figure, :5rET i' Chap. 19. of TJnherfal Geography, 441 YET the contrary, that the Height is the fame in all Places, feems more probable -, tho' the Va- pours are more elevated in fome Places than o- thers ; yet becaufe the Air is fluid and by it's Gra- vity tends downward, therefore the higher Parts prefs thofe below ; and thofe again others fideways, 'till all the Parts come to be alike high ; and thus it's fpherical Figure is proved the fame way as that of the Water is proved by Archimedes, Chap. xiii. for the Suppofitions here are the fame as there s which if falfe the Demonftration fails. DES Cartes alfo makes it oval, for a particular Reafon ; fee Chap. xiv. PROPOSITION XV. Vi'he Condenfation or Rarifa£Iion of the Air doth not alter it's Height, FOR not the whole, but a part only is con- denfed or rarified, fometimes here, fometimes there; which doth not alter the Height in one Place more than another: only there may be a greater Condenfation in one Part than in another : \yhich can alter the Height but very little. PROPOSITION XVI. The Altitude of the Atmofphere or Air is not only the fame in different Places y hut is alivays the fame both Summer and Winter. FOR tho' the Heat in our Summer doth at- tenuate our Air, and raife it more than in Winter, yet becaufe then there is Winter in another Place, the Air there is lefs raifed, and therefore a Part of our Air will flow there : and when our Air is low by the Cold, the Air of another Place that is hotter will 442 ^he Abfolute Fart Sect. VI, will move to us, 'till the whole Air be equally diftant from the Center. AND the fame may be faid as to Day and Night i for while at Night it is condenfed with us, and is low, it ratifies more in another Place, and moves to our Air 'till it makes a fpherical Figure ; and becaufe all things are every where equal, the Height will continue the fame every where •, and tho* it may rarify and condenfe more in one Place and Time than another, yet the Difference being fmall will not much alter the Altitude ; as we faid in the preceding Proportion. THE fame may be faid of the Clouds, Rain, or Vapours, in our or another Place, as from thefe a greater or lefs Altitude feems to arife : but I an- fwer, there is fcarce any time in which it doth not rain, or a Cloud fall, in fome Place or other ; and therefore while it rains in one Place the Air becomes no lefs than it was, bccaufe it rained be- fore in another Place, and fo it comes all to the fame thing, and the quantity of the Air is neither increafed nor diminiflied. P RO PO S iriON XVII. The colder the Air is, the thicker : and therefore it is for the moji part colder in Winter than Summer {in any particular Place), and likewife in the Night more than in the Day, and the grofs Exhalations f*-om the IVater in the Winter-time, increafe that Denfity, efpecially in the Evening and Morning, T F^ E Truth of the Propofition is clear from the preceding ; nor is it any Objedion, that a Part of the hotter Air moves where it is colder, and more low -, for it is not that but fome neighbour- ing Air that moves to the Place, becaufe of the continual Protrufion, or PrefTure 5 or tho* it came 3 itfelf. Chap. 19. of JJniverfal Geography, 443 itfelf, yet by coming there, it would become cold. PRO PO S irjON XVIII. There are commonly reckoned three Regions of the Air^ of which that is in the middle inhere the Snow^ Hail, and Rain are formed -, the firfi is that in which we live reaching to the middle Region •, the third is from the middle Region to the utmojl Bounds of the Atmofphere, even to the fiery Region, as the Ariftotelians fpeak, THE middle Region is colder than the firfl and third, which are counted hotter : becaufe the third contains more fubtile, fiery, and fulphureous Ex- halations which go up into it above the Place of the Particles of Water, or are thruft there being lighter. The Ariflotelians fay 'tis hotter becaufe near- er to the fiery Sphere, and colder than the firfl: ; be- caufe the Rays falling, join with thofe that are re- fleded from the Earth, and fo double the Heat. Moreover the Particles of the fubterraneous Fire coming out of the Earth are diffipated there in the lower Region ; and the middle Region being with- out all thefe Advantages muft needs be colder. PROPOSITION XIX. The nearer a Place is to the Pole, or the more dijlant from the Place where the Sun is vertical, the Place of the Air in which Rain, Snow, and Hail, is for m^ ed is the nearer the Earth, THE Caufe is, that the Rays fall more oblique- ly on the Places about the Poles than on thofe a- bout the Equator, and therefore being refraded are far removed from the Perpendicular, and thus the 444 ^^ Ahfolute Tart Sect. VI. the Heat becomes lefs, and the watery Vapours con- traft into lefs Room, and by joining form the wa- tery Meteors. COROLLART. THE Superficies of the firfl Region is oval, or rather elliptical, or like a Spheroid, bulging out under the Torrid Zone, PROPOSITION XX. The nearer a Place is to the Poky the third Region (in which the more fubtile and fulphureous parts tnove up and down) begins further from the Earth. FOR that Part of the Atmofphere which is nearer the Pole contains fewer fubtiJe and fulphu- reous Particles •, for the Sun brings fewer of them thither from the Earth. And a V:k Number being raifed there than in the Temperate Zone, and fewer in the Temperate than in the Torrid Zone^ and the ut- moft Bounds of the third Region equally diftant from the Earth's Center by Propofitionxvi ; therefore the beginning of that Region under the Frigid Zone» is further from the Earth's Center than it's begin- ning in the Torrid or Temperate Zone. COROLLART. THE Superficies bounding the fecond Region is as a Spheroid bulging in the Frigid Zone. Theff are all to be fhown to Students by a Diagram. PROPOSITION XXL The Rays of the Sun, Moon, and Stars, do not some dire^ly from the Heavens thro* the Air, to 3 ^^*K Chap. 19. cfUniverJal Geography, 445 our EyeSy hut turn a little afide from the Jtrait Courfe, as foon as they enter the Air ; ivhicb is cat' ledt by Writers in Optics^ their RefraElion. T H AT Part of Optics which treats of the Re- frad:ion of Light is very fine. Experience teftifies, that the Rays coming from any Objedl out ot one IVIediiim into another more grofs, or more fine, do refrad or turn afide : the Thing is plain from a common Experiment. Take a Vellel, to the Bottom of which fix a Globe of Gold, or Brafs, or Piece of Money, then go from the VelTel 'till you cannot fee the Money for the Sides of the Vef- fel, then fill the VelTel with Water and you will fee the Money ; which fhews, that the Rays coming from the Money as they go from the Water into the Air turn from their Courl'e, before they can come to the Eye •, which is called Refra^ion^ becaule the Line is broke, as it were, coming from Water to Air. THUS, Let the Center of the Earth be T, (Fig. 28) and L the Eye on it's Surface, and ^r/the Surface of the Atmofphere, or Air j and therefore no Ray can come to the Eye at L, which is under L/g for the Rays below would fall on the rifing Part of the Earth L i and thus no Star can appear by a ftrait Ray 'till it come to the horizontal Line L/^, but the Stars appear before that, while they are under Lg; for Example in S, from which no Ray can come ftrait to the Eye, but muft be refrad:ed ; t. e. the Line or Ray S/ coming into a thicker Medium at S, on the Atmofphere, is re- fraded and runs on in the Line/L, tho' it was di- reded to », and thus the Star appears before it comes to the horizontal Line L/^. THUS the Star in/ is not feen by the direfl Ray /r, but by the refrafled Ray r L, tho' it was diredted at the firft to m ; and therefore the Star at /appears higher by the Refradion than it really IS, 446 T^he Ahjolute Part S e c T. VI . is, it's Height being the Angle ^ L ^ or the Arch A^g, as if it were in the Point a when it is really in/. THIS being the Law of Refraction, that the Rays going into a grofler Medium, turn to the perpendicular at the Point of Incidence, as here / is the Point of Incidence, and T / the Perpen- dicular drawn thro* /, thro* the Superficies ^ r/ ; therefore the Ray S/« will be refraded towards /T that from/ « it may become /L. AND thus the Line or Ray r m becomes r L ; but the contrary happens when the Ray goes into a fine Medium, for then it goes from the Perpen- dicular. BESIDE it is the Nature of Refradion, that the Rays falling perpendicularly on the Superficies of another Medium, are not refradled, but only thofe that fall obliquely, and thofe are the more refrafted the more obliquely they fall. Thus the Rays S T,/T, M ^T being perpendicular to the Superficies are not refracted, but the Rays S/, jr that fall obliquely are, and S/ more than/r. FROM whence it alfo follows, and is manifeft by Experience, that the nearer the Stars are to the Horizon, their Rays are the more refra<5ted, and the higher they are, the lefs j and Aftronomers have found, that when a Star is twenty Degrees high, the Refradion is infenfible, tho' there is ftili a fmall Refradion. AND Mathematicians, fkilled in Optics, have by Obfer vat ions found the Laws of Refradion of all oblique Rays, and that in every Medium there is a conftant fixed Proportion between the Sine of the Angle of Incidence and of the refraded Angle (z. e.) between the Angle w/T and L/T, the Angle »/L being the Angle of Refradion; and {o in the Refradion of the Ray fr m. Therefore the fame Proportion that is between the Sine of the Angle Chap. 19- of XJniverfal Geography, j^^j Angle T/« and the Sine of the Angle T/L, the fame is between the Sine of the Angle T r tn and the Sine of T r L. Therefore if the Quantity of Refradtion be known by Obfervation at one Ele- vation of a Star, the Quantity of Refradion for all other Elevations may be known (t), P RO^ [/) It is of great Moment in the making of exadt Aftro- nomical Obfervations, to know the Refraftion which the Rays of Light fuffer in paffing thro* our Atmofphere. This was de- termined by the learned Mr Loivthorp, by an Experiment made before the Royal Society, and fhewn to be as the Sine of the Angle of Incidence and Refraftion. See Philof. Tranf. N° 257. But this Experiment being queftioned by the Ra^al Academy of Sciences at Paris, who had not the fame Succefs, [fee their Memoirs for the Year 1700.] Mr Z/0ic7^o;;^ repeated it at the Requeft of the Royal Society, and Mr Haujkbee alfo performed it with much greater Accuracy. See Haujkbee' s Phy- Jico Mechanical Experiments, p. 175, and found the Proportion betwixt the Angle of Incidence and Refraftion was as 1 000000 10999736 ; fo that the refradlive Power of the Air to bend a Ray of Light from it's ftrait CourJe in coming out of a Vacuum, or the Difference of the faid Sines, proportionabletotheSines themfelves,is 2641 ooooooParts And the Experiment being fe- veral Times repeated, he found that this refraftive Power ex- aftly anfwered to the Propor- tion of the di.%^t Penfiti^s of the Air thro' which the Ray paffed, fo as to be twice or thrice as large when the Air had twice or thrice the Deniity. Whence we have an eafy Rule for tinding the Refraftion in any Time or Place, as being always correfpondent to the Denfity of the Air. But the Denfity of the Air may be meafured by a joint Obfer\-a- tion of the Barometer and Thermometer. I'or as the Spaces, pofTcfled by the Air, are reciprocally proportional to the Weights that comprefs it [fee the Note upon Propofttion 7. above] and it's Denfity re- ciprocally as the Space it pof- fefles, the Denfity of the Air mull be proportional to the Weight that comprefTes it, or the Weight of the incumbent Atmofphere; that is, theHeight of the Quickfilver in the Baro- meter. And this will be the Cafe if the Heat of the Air remain the fame. But if the Height of the Barometer be known, the Denfity of the Air is reciprocally proportional to the Spaces marked againft the Degrees of the Thermometer in the Tube above. [See the Note to Propofttion 8.] Whence it follows, according to the known Theorem of compound' ing Ratios, that the Denfity of the 448 ^he Abfolute Tart Sect.

THE Caufe is fufficiently explained in the pre- ceding Propofition. We may add fome Experi- ments or natural Phenomena. When the Dutch wintered in Nova Zembla, the Sun appeared to them fixteen Days before it came to the Horizon, that is, when under the Horizon four Degrees, and that in a clear Sky ; and famous Aftronomers have the Air is always as the direft Ratio of the Heights of the Barometer, compounded with the reciprocal Ratio of the Spaces marked againft the De- grees of the Thermometer. ' For Example, at the time * the Experiment was made, * the Height of the Barometer * was 29 Inches, 7^ decimal * Parts, and the Thermometer * at 60, over againft which ' the Space of 137 Parts is ' marked ; Then, it muft be * enquired, what the Denfity * of the Air is, when the Ba- * rometer is up at 30 Inches, ' and the Thermometer 50 * degr. below the Line of Freez- * ing, then the Column of Air * in the former Experiments * will not poffefs above the ' Space of 126 Parts; fo that * the Denfity of the Air fought * for, will be to the Deniity * of the Air at the Time the * Experiment was made, as ' 30 X 137. to 29, 75X 126J ' eras 41 10 to 3748.5. And hence may be under- Ilood the Reafonwhy the Dutcb who wintered in AW« Xembla^ found fo great a Refraftion. See Se^. vi. Cbap. 19. Prop, 30. For hence we underftand, according to the Obfervations of the French and others, (fee Hiji. de r Acad. Scien. 1 700, 1 706, and La Me fur e de la Terre) that the Refraftions are greater towards the Poles than near the Equator, and greater in the fame Place in the Morn- ing or Evening than at Noon ; tho' there be no Difference perceived in the Height of the Barometer. For all this feems to proceed from the fame Caufe 'viz. the greater Denfity of the Air by reafon of Cold.

Therefore the Sine of the Angle T, 4, L hath a greater Proportion to the Sine of T, 4, 9, than the fame Sine T 4 L hath to the Sine T, 4, 3 ; therefore the Sine T 4, 9 is lefs than the SineT, 4, 3 -, and fo the Angle T 4, 3 is greater than the Angle T, 4, 9, and 3, 4, L than 9, 4, L, that is, than »/L ; and therefore the Line 4, 3 drawn out, viz. 3, 4, 6 the incident Ray for the refradled one 4, L will fall under S/, and the • ' ^ Star Chaf». ig. of Unherfal Geography, 45 x Star will be in 6 to caufe the refradcd Ray 4 L 5 and thus 'tis lower than when in S where the Al- titude of the Air was T/.

I THE Demonftration of this Propofition is manifefl from Prop. xxv. and xxvi •, and it alfo thence follows, that if the Air be lower and grofler in Places of the Frigid Zone than in the 'Temperate and Torrid Zone, the Sun may be feen there longer before the rifing and longer after the fetting, than in other Places that are higher and more fubtile •, for when 'tis more deprefled under the Horizon, and comes to it more obliquely and more flowly as in the Frigid Zone, it mufl then be feen much fooner in the Frigid than in the Torrid Zone. But 'tis doubtful whether the Air be lower in the Frigid Zone \ and tho* the Sun be feen fooner before it rife, whether that may be only on Account of the grofihefs of the Air i of which afterward.

THE C H AP. 19. of JJniverfal Geography, 4? r THE Refradiion of a Star is equal to the Dif- ference bcicween the obferved Altitude, and x\\-, .

And from thence 'tis found, that two Refradiions are fufficient to find the Al- titude of the Air T F, and the Rule of Propor- tion between them ; which I take Notice of be- caufe 1 fee Kepler^ in his Epitome of Ajlromm^j "p. 6^, takes three Refradlions, tho* he did not try this Method himfelf. THE Refolution of this Problem may be alfo had by the Rule of Poficion, by affuming T/in a certain Proportion to T L, and trying if, by that Aflumption, the Sines of the four Angles T/L, T/«, T r L, T r w will be proportional. THEREFORE, in the Triangle /LT, let there be found the Angle T fh from having /"T, T L, and T L/. And likewife in the Triangle T L r, find the Angle T r L from having T r, TL, and TL r. LET there be then taken the Sine of the Angles T/L, Tfn^ TrL, Trjn-, and let there be a fourth Proportional taken to the Sines T/L, T/», TrL. And if T r;« be equal to this fourth Proportional, then the afiumed Height of the Air T/ will be juft ; but if the Sine T r mhe greater ichan the fourth Proportional, then T/ mufl: be taken lefs ; but if lefs, then it mud be taken more j ?ind fo always 'till they become equal. EXAMPLE. SUPPOSE the Virgin* s Spike, or any other Star, or the Sun, to be feen in the Horizon L/ ^ when 458 72?^ Abfolute Part Sect.

AS 9,995,992 : 9,998,200 : : 9,992,159 : 9,994,366. AND with that fourth Number compare the Sine of the Angle T r w, which is 9,994,500. A N D we find that this Sine is very near to that fourth Number ; and therefore the alTumed Altitude of the Air, viz. i of a Mile, is not far from the Truth. And if any one defire it more accurately, he may alTume another Altitude, and work the fame way, 'till the Sine of T r m be G H A p . 19. of XJniverfal Geography. 4 ^9 nearer to the fourth Proportional •, or, by the Rule of Falfe, having it twice too little, you may find the true Altitude as near as poffible, for it cannot be found perfei5tly true *, becaufe a fmall Diiference in the Sines changes it very much if it be but half a Minute : and befides this the Canon of Sines mud be very exaft. WE conclude therefore, that the Height of the Air is about the 2000 pare of the Semidiameter of the Earth, which is 1,633,190 Perches ; and the Altitude of the Air 816 Perches, one Perch being twelve RhinlandiJiD Feet : but 'tis better al- lowed to be half a German Mile, for the Refradlion L/;? was found, hyTycho, to be greater, and may be thirty fix or forty eight Minutes ; and then the Height of the Air will be one Mile. THE Height of the Air being known, there is alfo known the Proportion of the Denfity of the Air to that of the Ethereal Matter, or the Law of Refradion, in that Air making fuch Re- fraftions in fjch Altitudes, i. e. the Proportion of the Sine T/L to the Sine T/77, before found, is the Proportion fought. AS 9,995,992 to 9,998,200. And the Reafon why thefe Refractions are fo fmall is, becaufe we fuppofed a clear Air, not much differing from the Ethereal Matter in Denfity j as fome have imagined. MOREOVER, whether the Altitude of the Air be the fame in all Places and Times may be known •, if we ufe the fame way two Refradlions at two Altitudes in a different Air and Time. And that Students may underftand thefe Secrets of Nature, I have, that they may try a Calculation, fet down Examples from Tycho^s Obfervations, who obferved the Refradlions of the Sun and Moon for every Degree of their Height ; and be- caufe they differ from the Obfervations of Lanperg^ made 460 lie Ahfolute Tart S e c t .

Geography, 461 LANS BERG fets down the fame Refraaions for the Sun and Moon ; and Tycho makes a fmall Difference near the Horizon, thofe of the Sun grea- ter, and at the fifth Degree equal ; and afterward the Moon's Refraftions Ibmewhat greater than thofe of the Sun : I confefs I do not fee why, except it be attributed to the weaknefs of the Moon's Light. And moreover, Tycho omitted Seconds, which arc not to be negleded, if they approach near fixty, for they are of ufe in calculating the Height of the Air. But as for the Refradtions of all the Stars they are equal, or very little different, if in one Air ; but if the Air be grofler, the Refradions are greater. For Example, the Dutch, at Nova Zembla, found in Winter that the Sun began to appear after a Night of fome Months, when it was 4 Degr. un- der the Horizon, at leaft it's Limb ; therefore the Refradlion w/L is 4 dc^, 30 7nin. the Caufe where- of none have fufficiently explained. AND then, when it was 3 degr. 45 mm. under the Horizon, they faw it elevated above the Ho- rizon 30 min. viz. it's upper Limb ; therefore the Refraction mrL, (for we muft conceive inr s to fall under the Horizon, or r L^ to be 30 ;«i/7.) will be 4.degr. 15 min. and r LT 90 degr. 30 min. From this may be found the Altitude of the Air L/, and the Denfity of the Air at Nova Zembla, which was clear at the time of Obfervation. And the Altitude of the Air is thereby found much greater, almoft two Miles j nor will the fuppofition of a greater thicknefs in the Air help the Matter, as we fhall fhev/ in the following Propofirion ; becaufe the Angle T/L cannot be greater than 85 degr. 30 i7iin. (i{ nfL be 4 degr. 30 tnin.) tho' it wUl be greater if ^/be fup- pofed lefs than two Miles ; therefore the Truth of the Obfervarion may be juftly doubted of, feeing there is no fuch Obfervation any where •, yea the contrary hath been obferved in the fame Place, fee 462 Tlje Ahfolute Part Sect. VI^ fee Chap. xxvi. Prop. xiii. at the end. Befides this, there can be no Reafon given why the Air, after fo" long abfence of the Sun, fhould be higher than when the Sun left tliem after it had been prefcnt a long time •, rather tiie contrary fhould happen, the Air being made grofler and lower by Condenfati- on, as fome may urge that count the Height of the Air inconftant. Yet, when I confider thefe things more accurately, three Particulars occur to me that might confirm that Appearance and the great Refraction : for the Obfervation cannot be denied, confidering that the Obferver underftood Aftrono- my, and faw the Sun above the Horizon for fome Days after, when it was ftill under the Horizon ; nor muft we doubt of the Number of the Days in the long Night they had, for when they came back they counted the fame Day of the Month, as their own People did, which could not be if they had miftaken before. For if we admit fuch an Altitude of the Air as is inconfiftent with the Refracftions in the Temperate and Torrid Zone:, we mull fay the Air is of the fime Height every where as truly in the Torrid and Temperate., as in the Frigid Zone. But, in the "^ or rid and Tefnperate., the upper Region of the Air is fo fubtile, that it doth not caiifc Refraction, but only the middle Region of it ; and therefore no wonder if the Refractions in the Torrid and Temperate Zones are lefs ; for the Air that caufcs them is lower, which fhould caufe the Ivefraftion to be greater ; yet it muft be much more rarified than the other Air. But to this it may beobjefled, that the Obfervations of the Sai- lors were made in a clear Air, as themfelves fay \ to which I anfwer, that 'tis not probable that the Air was then fo fubtile as the cleared Air in the Torrid and Temperate Zone. Secondly, it may be faid that the Air of the Fripd Zonc^ when the Sun returns to it after a long abfence, is firfl refined in the Chap. 19. of XJniverfal Geography. 463 the upper Region, and that the middle is fomewhat more grofs, and therefore the Sun is feen by two Refradions, as the Stars are thro' Air and Glafs, and a double Retra6lion depreflcth the Star under the Horizon more than a fingle one, and fo the Altitude of the Air of one Mile, or three Quar- ters, will be enough. Nor can it be objedted^ why doth not the fame thing happen when the Sun departs from that Air, and the long Night begins ; for then it is probable the Difference of the tiiick- nefs of the Air is lefs, becaufe of the Sun's long Continuance ; or we may fay the Exhalations are more grofs, in the Mornings of that Zone, after that long abfence. Thirdly, if a double Refradion doth not fatisfy, and it will not be granted that the upper Region caufes no Rcfra6tion, as was Hiid, then it mull be granted that the Air in that Place of the Frigid TLone was then much higher than in our Temperate Zone^ and alfo much grolTer Cfor 'tis only the Altitude that leflens the Refra- (5lion) : but if there be a great thicknefs, the Re- fraftion is much more increafed thereby, than 'tis diminifhed by lelTening the Altitude. But the firfi: of thefe three Caufes is beft, that fuppofes the Al- titude of the Air to be two Miles Cfor it cannot be lefs in Nova Zemhla where the horizontal Re- fraftion faid to be 4 degr. 30 min.) : the other two lie under feveral Difficulties. We have faid it was the thicknefs of the Air that was the Caufe why, the Altitude being the fame, the Sun Wvis not feen for fo many Days after it ceafed to rife on the third of November \ and fo we muft anfwer, that the Caufe may be the fame why the fame Dutchtnen did not, on the thirtieth o^ May 1596, fee the Sun in the middle of the Night, in the Latitude 69 degr. 42 jnin. when it was not one Degree under the Horizon. But we have laid too much of this, occafioned by the difficulty of the thing -, there 2 muft 464 I^Je Abfilute Tart Sect. VI. mult be, for an accurate knowledge of it, molt accurate Obfervations. Yet we muft not thinks that if Obfervations of a Star, in different Eleva- tions, do not give the fame Altitude, that there- fore it hath different Altitudes, on account of the Difference of the Denficy of the Air, which is greater the nearer the Horizon ; and therefore Ob- lervation will give a different Altitude, tho' it be the fame, for, in the Calculation, the Denfity, and confequently the Refraction, is accounted the fame* PROPOSITION XXXI.

Ma- thematicians, who have written of the Twilight, will 2 have Chap. 19. of TJnlvei-fal Geography, 469 have the incident Ray in/, which makes the reflect- ed Ray/L, to come from the Sun j \ and becauleno Ray can come to /"from the Sun, while tiie Sun is un- der the Tangent/^ i i therefore when the Sun comes to the Tangent fhs^ for Example to i, then doth the Ray begin to come to/; and becaufe they will have the Refleftion to be from/, as from a con- cave Mirror, therefore T fh muft be equal to T/L ; and becaufe the Sun is found to be 18 d'^^r. under the Horizon, nfs muft be 18 dcgr. and L//? 162 degr. and T//3 or T /"L 8 i dtgr, and LT 9 degr. from whence T/ is found 174 German Miles Cas Clavius and Nonius make it) and the Air about eleven Miles : nay Alhazen and Vilellio make it thirteen Miles. SO great an Ahitude of the Air is not to be al- lowed as difagreeing with other Ph:Enomena, and being founded on a filfe Hypothefis, that the Ray gbsy which makes the refledled Ray /L, comes from the Sun itielf, which is filfe •, for it comes, by Reflection, from another Ray, for Example from the Ray g I. And that it is not necefiary to make a fmall Light in j, that the Ray fg fliould come from the Sun itfelf, but that another Ray may ferve, is proved from hence, that we fee, in the wefl:ern Air, fome Light before the Sun rifes, tho' 'tis certain no dired Ray can come from the Sun to the wefl:ern Air, but from another Particle of Air, for Example from/and -, and fo the re- flected Ray L m comes from the incident Ray fm which is reflected from the incident Ray gf^ and again gf from another g L ; which perhaps comes again from another. Secondly, 'tis worth remark- ing, that they have made the Reflection from the Air as from a concave Mirror ; the Center of which Cavity isT the Center of the Earth, which is falfe j for the Rays refleCt from the Air without any regard to the Center of the Earth, but to their Su- fi h 3 perficies, 470 T^he Ahfilute Tart S e c t . V I . pcrBcies, as is evident from the Ray L m^ which comes from the v/eftern Air to L •, for if it came from m as from a Concavity, it's incident Ray fhould have come irom the Place y, whereas it comes from o, or between/ and o. Therefore the Kay L m fo reflcded, is from the Particle m as the Figure required. And in the Air there are Parti- cles oi very different Figures •, and fo no wonder if they make Rcticclions thro' the Air every way. PROPOSITION XXXIX. Suppofiug the Twilight is net made by one hut a douhle RefietUofi, to find from thence the Altitude of the jiir^ luhich ?nay agree better -with other ObfervU" iions. IT was faid in the laft Propofition, that the Rayg/^/", {Fig. 29.) which makes the firft reflect- ed Ray in the Beginning ot the Twilight, does not come from the Sun itielf, but that 'tis refleded in g ; let therefore the incident Ray be ^ / fwhich may touch the Earth ?;;/>, and fo Ig is the firft Ray which can come to g) and let us now fuppofe it to come from the Sun itfelf immediately, and by Re- fraction to be turned a little afide •, that is, let QL be the Ray from the Sun, and let Ipg be the refract- ed Ray, and_g^ J the reflected Ray, and/L the fe- cond reflected Ray. The Altitude of the Air T/ is to be found •, and, becaufe the incident Ray QJ refracts into g /a-, let us fuppofe the Angle of Re- fraCtion |; /x to be 30 ?nin. and that the Center of the Sun is 17 degr. under the Horizon, when the Twilight begins ■■, therefore the Limb of the Sun will be 16 dfgr. 45 min. under it, and fubftraCling the 30 min. ibr the Refraction, and Angle nKx will be 16 degr. 15 min. which is the DeprefTion of the Sun's Limb after RefraClion.

IVh-j the IVind jnay blow in a Line perpendicular to the Horizon. T tl E Ileafon is, that the Air furrounds the Earth in a fpherical Figure, and the Air is ihruft about for the moil part in a great Circle of the Earth ; and tho' the Air may be alfo thruft in a tranfverfe Line, yet becaufe the Air doth not prefs fo much, or refills more at the Sides, therefore the Wind blows in the middle. W E fliall underftand this better if we confider the firft Caufe of the Winds. For the Sun thrufts the Air to all the Points of the Place that it is ver- tical to •, but 'tis not received in all thefe Points, as was faid. l^ we then confider great Circles to be drawn from that Place, and between thefe, thofe to which the Air is forced, or in which 'tis received, all the Places of the Earth fituated in that Circle, or Semicircle, will feel the Wind coming down perpendicularly ; becaufe all great Circles that pafs thro' any Place are perpendicular to the Horizon of that Place j for the fame Reafon, if the Wind break out from a Cloud broke, or dif- iblved, thofe Places that are fituated, beyond thofe Circles will not feel the W^ind, tho' the Air move above their Horizon ; becaufe 'tis not perpendi- cular, but oblique to that Horizon. YET C FT A p. 20. of Vniverfal Geography. 485 YET 'tis not generally true, that the Wind goes down perpendicular to the Horizon i for ot- ten it blows in the Air tranfverfly. THUS' we may Tee the Smoke that comes out of a Chimney is not carried by tiie Wind all one way, but a part of it goes another way. PROPOSITION XII. fFhy the IVinds biozv with [ome Interruption^ rc.Jling as it were for a TimCy and on a fudden return with Force ; and why on the Sea they are more conflant. THE Reafon I fuppofe is, that the Caufe of the Wind is not conflant, and takes fome time to gather it's Strength ; and the Exhalations being more conftant on the Sea, and the Motion of the Wind lefs hindered ; therefore that Change is not fo fenfible there, tho' there is fome Change as to the Degrees of blowing. PROPOSITION XIII. M'^hy no Wind blows perpendicularly from the Air or Places of the Earth. ARISTOTLE, in his fecond Book of Meteors Chap. ix. treats very obfcurely of this Oueftion i fo that his Followers do not agree about his O- pinion : nor fliall I be at Pains to write their O- pinions. The Caufe which feems to be more intelligible is, that the Air being thrufl down to the Center of the Earth cannot go that way, but is hindered by other Vapours that are forced up-, and the great Refiftance of the Air below caufes the Force downwards, to tend fideways : v/hich is the more probable becaufe that which I i 3 tbc 486 *r/v Ahfohife Tart Sect. VI. the Wind confifts of is lighter for tlie moft part than that Air \ and aifo more rarified than the Air near the Earth. , , ,: PROPOSI'TION XIV. Wh-j the Eajl JVindi are more frequent than the JVeJl. THE Caufe of this is manifeft from Prop. 10, where we made the Sun the chief Caufe which rari- fies the Air from Eaft to Weft ; and therefore the Air is more prefied towards the Weft : and this cannot be hindered except there are a great Quan- tity of Exhalations or Clouds in the weltern Parts, which is not very frequent. PROPOSITION XV. Why the North and Eajl IVinds are mere ft r org and Jevere^ and the South and PFefi IVmds ^nore iveak and gentle. THE Reafon is becaufe the North Air is grof- fer on account of the Cold, and the South Air in our Zone is more rarified by the Sun \ and the more rarified the Air is, it's Motion is the lefs forcible ; yet the South Winds are cold, dry, and ftrong, in the Temperate Zone^ contrary to ours, no lefs than the North Winds are to us. But the Eaft W^inds are fevere or more intenfe on another Account, viz. that they arife for the moft part from the Rare- faction of the Air by the Sun, which is continually carried from Eaft to W-'eft, and fo is forced more towards tlie Weft. But 'tis likely there are other Caufes which hinder or promote this Motion. The Portuguefe Sailors call the North and Eaft Wind Brxjas ; but the South and Weft they call 'Afjdavalcs, P RO' C H A p. 20. of Uiiivetfal Geography. 487 PROPOSITION XVI. IPlpy the South and IVefi Winds are found to he hotter than the Eajl or North, which have a much greater frigorific Power. THUS is the Queftlon ufually propofed ; but we mult knov/ 'tis not to be underftood gene- rally of all Places, but only thofe in our Zone •, for in the other Temperate Zone, towards the Sourh from the Equator, the contrary holds good -, for in thole Places the North Winds are hot, and the South more cold, and fo the Nature of the I'hing requires. For the South Wind being more hot, and the North more cold, proceeds hence diat the South Winds come from Places near the Torrid Zone^ and the North Winds from the Frigid Zone ; but the contrary happens in Places near the Antar5]ic Pole ; for the North Winds come to them from the Torrid Zone^ and the South Winds from the Frigid. But another Account is to be given of the Eaft and Weft Winds -, for the different Places of the two Temperate 'Zones are not to be regarded here. Firft we faid in the preceding Propofirion, that the Weft Winds are lefs frequent in all Places \ the Caufe of which is the i'ame with that for which, the Weft are found to be hotter ; viz. becaufe they blow for the moft part in the Night-time after Sun fet, where the Air, prefTed to our Place, is hotter or lefs cold than the Air of our Place ; as being further from the fetting Sun than the Place between us and the Sun then. There is another Caufe which alfo holds good in the Difference between the North and South Wind i "ciz, that the Weft Winds do not blow fo Itrongly, but with fome flownefs •, for 'tis known that a Gile or Breeze is the colder the more fiercely it blows i I i A. tho' 488; The Ahfohtte Fart Sect.

PROPOSITION XVIIL IFhy the JVinds in Spring and Autumn blow more Jlrongly and frequently , than in the Heat of Summer or Cold of Winter. I fuppofe 'tis fo in Spring, partly becaufe of the melting of the Snow, efpecially in high Places ; partly becaufe the Pores of the Earth are then open, and fend forth more Exhalations ; and part- ly becaufe the Air and Vapour then becomes more rare ; being condenfed in the Winter. Moreover, there falls much Rain a Month before the Spring, and in the Spring itfelf, becaufe the moill Con- ftellations are in thofe Places of the Zodiac, into which when the Sun enters the Spring begins. But the Caufe of the frequent Rains, and blowing of the Winds in Harveft, is, that the Sun then draws up fome Vapours ; but the Heat being fmall, it only draws thofe that are groITer and pot fine enough. But in the Summer there are few 490 ^he Ahjolute Part Sect. VI. few Winds, for the fame Caufe for which there are Rains but feklom then j njiz. that the Sun does too much attenuate the Exhalations, and fuffers them not to go fo much together as is necefla- ry to produce Wind, Which Caufe is not indeed general, nor always true \ nor is it generally true, that there are no Winds in the hot Summer, but only that it often happens fo. In a fevere Winter there are few Winds •, becaufe few Vapours are then exhaled, and thofe that are raifed are either con- denfed to Snow, or elfe are not fo rarified or difli- pated thro' the Cold, as to caufe a Wind. PROPOSITION XIX. In what Altitude^ or in what Region, of the Aiiy do the IVinds begin to blow ? SOME think they are not above the lower Region of the Air ; becaufe the Tops of high Mountains, as Olympus, are found to have no Wind on them. I doubt the Truth thereof, for the- Smoke from the Top of Mount Ai^tna is feen to be tofied here and there ; and therefore I think there may be fuch a Commotion of the Air in the higheft Region alfo. '; PROPOSITION XX. How far ma-j one and the fame JVind blow ? T H E R E is a great Difference in this Matter ; for the Winds blowing from Eaft to Weft, under the Torrid Zone, feem to go round the Earth ; and thofe alfo that blow thither from the South or North ufe to accompany the Seamen a great way for many Day?. The fame feems alfo true of cal- lateral Winds ; but here lies the Difference, that the fame C H A p. 2 1 . of JJtiherfal Geography. 49 1 fame Winds differ in different Places, as we faid under Prop. 10. at the end of the Explication of the firfl Ciufe. CHAP. XXI. Of the Khids of M^ifidsy and of I'empejls. N the preceding Chapter we gave the Divi- fion of the Winds, their Differences, or rather different Names, which they have from the feveral Points they feem to blow from. This Divifion was therefore accidental, and rcfpefting a certain Place on the Earth, v>?hich thefe Points referred to. We fliall in this Chapter give other Divifions and Properties of the Winds belonging to certain Places of the Earth, or certain Times of the Year ; tho' we wifh we had more and exafter Obferva- tions of them. But we fhall produce fome that we have gathered with much Pains from the Journals of Sailors. PROPOSITION I. So?ne IVifids are conjlant, others inconftant., THE conftant are fuch as blow at leaft one Hour, or two, from the fame Point. THE inconftant are fuch as blow one v/hile •from one Point, and another while from another, in a fmall Time. THE Caufe of tKeir fhort continuance in one •Point, and of their changing on a fudden, feems 5 tc 492 Tlje Ahjohte Part Sect. VI. to be firft their proceeding from a general Caufe, or a Caufe that is more or lefs durable. T H US the Winds that proceed from the Mo- tion of the Air with the Sun are conllant ; and thofe likewife that proceed from the melting of the Snow, efpeciaJly in high Places. 2. There being no fuch Vapours in that Quarter the Wind blows from as are fit to make Wind. 3. If the Air about the Cloud, from which the Wind comes, be thicker, and hinder it's Paflage ; but if the Air is not thick or clofe together, and but a few Vapours, here and there, in the feveral Quarters -, or laflly, if the general Caufes do not operate there, then the Wind is found to be changeable, and for the moft part gentle. PROPOSITION II. There n a General and Particular Wind. THAT is called by Sailors a General Wind which blows in feveral Places at one Time, thro* a large Trad of the Earth, almofl: all the Year round. AND this Wind is hindered, i. In Places of the Sea near Land •, for here they drive againft the Vapours that come from other Points -, and therefore *tis in the middle of the Sea that this General Wind is obferved. 2. There may alfo blow another Wind in the middle of the Sea, when there is a Cloud, or lb me other Caufe in another Point, ftrong enough to produce Wind. From thefe two Caufes it is that the General Winds are not fo conflant as they might be other- wife. THESE General Winds are found only be- tween the Tropics round the Earth, except in fome Places where they are feven Degrees beyond the Tropics ', C H A p. 2 1 . of Umverjal Geography, 493 Tropics •, and they are ever from the Eaft, or from collateral Points, as South-Eall and North-Eaft, and that the whole Year round •, yet not always with the fame Degree of Force in all thofe Places, but they are hindered in fome Places more, in others lefs. They are mod conftant in the Pacific Sea ; viz. that Part of it which lies between the Tropics-, fo that the Ships which come from the Aquapulco^ a Port in JSew Spain in America, to the Phillippine Iflands, that is, from Eafl: to Weft, often fail three Months widiout ever changing or fhifting their Sails -, having a conftant Eaft or North- Eaft "Wind: nor did ever any Ship yet perifh in that vafh Voyage of one thoufand fix hundred and fifty Miles. And therefore the Sailors think they may fleep there fecurely : nor is there any need of taking care of the Ship, when that General Wind carries them ftrait to their defired Port, the Philippine Ides ; near to which indeed there are fome other Winds that come againft the General Wind. And thus 'tis alfo in failing from the Cape of Good- Hope to Brafil in America -, in the middle of which Voyage lies the IQe of St Helena, to which they commonly go as they return from India to Europe, and lies about three hundred and iifty Miles from the faid Cape : which is run oft- times in fixteen Days, and fometimes in twelve, as the General Winds are more or lefs ftrong ; and the Seamen are as fecure when they come to the fame Parallel of Latitude with St Helena (for the Cape is beyond the South Tropic) •, their chiefeft care is to obferve that they do not pafs by the Ifland, as 'tis very fmall, for if they pafs it but the eighth part of a Mile, they cannot return to it for the eafterly Wind. Thus they are forced to go to Brafil for frefh Water, or the other Ifland called Afcenfion with great lofs of Time. IF 494 ' ^^ Abfoliite Tart Se ct. VI, I F it be afked how they fliil when they come the contrary way,i. e, from the Philippines to New Spain, or from Brafil to the Cape of Good- Hope going to In- dia ; in thefe Voyages the Reader mult oblerve a threefold Artifice ; for either they fail the Sea be- yond the Tropics, (and thus do not go to St Helena while they go from Europe to India)^ or when they fail within the Tropics they do not go diredly from "Weft to Eaft but obliquely, from the North, or a Point collateral to it, to the South, and fome Point collateral to it ; or laftly, they chufe thole Times for fiiling in which they know the general Wind is often diverted : but this laft feldom happens, and therefore the other two are more frequent j of which we fhall fay more in the Chapter of Navigation. THERE are then two Seas under tht Torrid Zone in which the general Wind, from the Eaft and collateral Points, prevails thro' the whole Year ; viz. that between South Africa and Brafil^ and that between America and the Oriental Ides, of which the Philippines are a Part. And the third Part of this Sea in the Torrid Zone^ viz, between South Africa and the Oriental Ides, is not without the general Wind ; though 'tis often interrupted bccaufe of the many I (lands there •, and more in fome Places than others. This Wind blows moft between Mozambique^ in Africa^ and India^ in the Months of January^ February, March, April ; and in the reft of the Months other Winds blow, of •which in the following Propofition : This general Wind is more hindered in the Seas among the Indian Ifles. The Eaft Winds begin to blow hard in the Month of May at the Ifle of Banda^ with fome Rain ; and at Malacca in September ; and in other Places otherwifc, as will be fhewn in the following Propofition. YET this general Wind does not happen alike near the Tropic in all Places, but extends itfelfditfe- rently -, C M A p. 2 I . of Uiiiverfal Geography, 49 j rently ; for the Tropics are diftant from the Equa- tor on both Sides twenty-three Degrees, and thirty- Minutes ; and the general Wind extends itfelf in one Meridian to the Latitude of twenty Degrees j in another to fifteen, in another twelve. THUS in the Indian Ocean, when the Eafl; or South- Eaft Wind blows, in the Month of January and February, 'tis not fenfible *tiil you come to the fifteenth Degree of Latitude. S O in going from Goa to the Cape of Good-Hope^ they have not the general Wind 'till they come to the twelfth Degree of South Latitude ; which th^ have to the twenty-eighth Degree of the fame La- titude. L LK E W I S E in the Sea between Jfrka and America, between the fourth Degree of North Latitude, and the tenth or eleventh Degree, Seamen have not obferved the general "Wind to blow i for when they have failed from St Helena be- yond the Equator with that Wind, to the fourth Degree of North Latitude, then they have been without it 'till they came to the tenth Degree of North Latitude ; from which to the thirtieth De- gree the North- Eaft Wind is found to blow con- llantly, tho* that thirtieth Degree is feven Degrees from the Torrid Zone ; yet in the Parallel of fix, feven, or eight Degrees of Latitude, ^c. it blows in fome Places, but in the tenth Degree in all Places 'till they come to the thirtieth. In the fame manner beyond the Tropic of Capricorn, between the Cape of Good-Hope and Brafil, the South- Eaft Wind, blows to the thirtieth Degree thro* the whole Year. AND tho*, as we fald, this Wind is not fenfibb on all Shores, and much lefs in the inland Parts, yet on fome it is fenfible enough ; thus on the Shores of Brafil, and on the Shores of the Kingdom of Lowango^ in Africa, the South-Eaft Winds blow daily. 496 ^e Ahfohte Tart S e c T. VI. daily, although other Winds are mixed with them. THERE is a threefold Caufe affigned by Na- turalifts for this General Wind (for the Antients knew nothing of it, nor of the Torrid Zone itfelf ). Some think the Sun's moving from Eaft to Weft is the Caufe of it ; becaufe it rarifies the Air that it goes over; which Rarifadion follows the Sun, ftili thrufting the Air before it. OTHERS, viz. thofe who fuppofe the Hea- vens fixed, and the Earth to revolve, are of Opi- nion, that the General Wind comes from the Earth's moving from Weft to Eaft, and the Air with it, but not fo faft as we ; and therefore that we go againft the Air, or the Air againft us, from Eaft to Weft. A third Caufe is brought by Des Cartes, which is altogether new -, {Pari 4. Prop. 49. of the Prin- ciples) where he endeavours to fliew that the Moon caufes this Motion of the Air as well as the Tides ; but becaufe the Knowledge of his Opinion requires alfo the Knowledge of his other Suppofitions, we ihall not fay any thing of it here ; being afterwards to fhew that it cannot be fo. The firft Caufe pleafes us beft ; and the fecond feems not to be re- ceived *, becaufe feveral of the Copernicans do not admit it ; and no Reafon can be thus given why it ihould blow only within the Tropics, and not alfo beyond them («j. PRO^ (u) Dr Halley, a Perfon well rience. But he only takes No- flcilled ill Meteorology, as well tice of fuch Winds as blow in as in all parts of Pliyfics, has, the Ocean; there being fo much with extraordinary Accuracy, inconftancy and variablenefs in profecuted the Hiltory of the Land-Winds, that from them Conftant periodical Winds ; a Perfon can make out nothing which he deduces not only from clear or certain, the Obfervations of Seamen, Firft of all then, he divides but alfo from his own Expe- the Ocean into three ample Seas C H AP. 2 1, of Vniverfal Geography. 407 PROPOSITION III. Some U^inds have a fiated Time and Period, others are unfixed, and blow at uncertain -limes. THOSE are called Stated and Periodical Winds that blow at certain Times of the Year, and Seas, 'viz. I. The Atlantic. 2, .T\\t hdian ; and, 3.TheP«- cijic Sea ; proceeding to de- fcribe in order, the Winds that generally blow in each of thefe. In the Atlmitic Ocean, thro' the whole Year, blows the Eaft Wind ; yet fo as to turn a little South or North, accord- ing to the different Situation of Places. Of which Turnings this is the Sum. 1 . Seamen near the African Shore, as foon as they have failed paft the Canary Iflands, about twenty eight Degrees of North Latitude, obferve the Wind to blow pretty loud from South-Eaft. This Wind conti- nues with them in their Courfe fouthward 'till they come at the tenth Degr. of North Latitude, provided they be an hundred or more Leagues from the Coaft of Guinea, between which De- gree, and the 4th of North La- titude, there are interchangeably frequent Calms and Hurricanes. 2. They who fail to the Ca- rihhee Illands, as they approach the Coaft of America, perceive the N. rth-Eaft Wind more and more to retire eaftward, in- fomuch that fometimes it is full Eaft; fometimes alfo, tho' rare- ly, it may turn a little to the VOL. L South ; whofc violence they ob' ferved perpetually to abate. 3. As to theconUantWinds, they don't extend further than twenty eight Degrees North Latitude, to the Coaft of Afri- ca, and near the Border of A~ merica they go to thirty, thirty one, or thirty two Degrees. The fame is obfervable South of the Equator; where, near the Cape of Good-Hope, the Limits of thefe Winds are three or four Degrees further diftant from the Equinodtial Line, than on the Coafts of Brafil. 4. From the fourth Degree of North Latitude to the above- mentioned Bounds on the South Side of the Equator, the Wind is obferved almoft perpetually to blow from the intermediate Parts 'twixt South and Eaft, tho' for the moft part 'twixt Eaft and South-Eaft ; yet fo, as that thofc who fail near the Coaft of Africa have the Wind turn.^ ing rather South, but ap- proaching America they obferve it decline fo much to the eaftward, that it almoft blows direft Eaft. I had Occafion to tarry for the Space of a Year on this part of the O- cean, during which time the Changes of the Weather were Kk fQ 498 The Ahjolute Fart S e c t. VI. and ceafe for a fct Time, and then begin to blow again •, Tome of thefe are anniverfary, others blow after fo frequent, that I had fuffic'- ent Employment in obferving thefe Matters. I found there- fore the Wind ahnoft always to poflefs the third or fourth Point from the Eail. As oft as it approached nearer the Eaft, it blew more vehemently and raifed a Storm ; but when it came from the Points more fouthward, it was much more calm, and made the Air clear. But I never perceived a Wind blowing from Eaft to North, or from South to Weft. 5. Thefe Winds undergo fome Change, which is owing to the different Seafons of tlie Year. i"or when the Sun pafTes the Equator northward a pretty way, this South-Eaft Wind, elpecially in this narrow Tracl of Sea between Guinea and Braftl, declines fomcwhat more to the South, as the North- Eaft does to Eaft. And again, upon the Sun's entering the Tropic of Capricorn, tlic South- Eaft Wind approaches nighcr to Eaft, as doth the North-Eaft to North. 6. There is found a certain Tradl of Sea in this Ocean, which, near the Coaft of Gui- nea, extends for the Space of five hundred Leagues, from Mount Leo to StTho?7iai's Ifle, wherein South, or South-Weft, Winds conilantly blow. For the South-Eaft Wind having once palTed the Equator be- comes conftant, which in our fourtn Obfcrvation we demon- ftrated to blow to the South of the Equator. About eighty or one hundred Leagues from the Coaft of Guinea, it turns by degrees fouthward, and having turned that Point, it declines to Points near tlie Weft, 'till touching the very Shore, it either obtains the South-Weft Point, or that 'twixtitanddirccl Weft. Such kind of Winds on this Coaft are fi.\' J ,tho' frequent- ly interrupted with Caims and 'lempefts, which violently pro- ceed from any Air. Seamen alfo, much to their lofs, fometimes find the Winds eafterly ; which being attended with Clouds and a grofter Air, are very un- wholeiome. 7.'Twixtthetenth and fourth Degrees of North Lat in that Trad which is bounded by the Meridians of Cape Ferd, and the remote Iflands adjacent to it, I know not if I can fay that any Wind blows either conftant or variable. The Calm is almoft perpetual, the Thunder and Lightening ex- treamly terrible, and Rains fo ve- ry frc.]ucnt, that from them the Tradt is named rai?i)\ If there happen any Winds they go off into Blafts, blowing with fuch inconftancy, that they don't continue for the Space of one Hour, without Calms; and the Ship:, of the fame Fleet, which are all in Sight one of another, have each ot them their proper Winds. On which Account fail- ing is fo diihcult in thefe Places, that Chap. 2 1. of JJniverfal Geography. ^qq after they have ceafed half a Year, and others re- turn in a Month's time : and fome blow once a Day. that rometimcs Ships with great difficulty f.iil thefe fix Degrees in whole Months. From the three foregoing Obfcrvations two things may- be expLiined, which Alariners experience in failing betwixt Europe and India , or Gui- nea. In the firft Place, that tho' this Sea, in that Part where it is narroweft between Guinea and Brafil, extends no lefs than iive hundred Leagues, yet with great Difficulty Ships, fleer- ing their Courfe fouthward, pais this Traft, efpccially in the Months Jiil^ and Augujl ; which arifes hence, that during thefe Months the South-Eall Wind, blowing on the South of the Equator, pafies it's or- dinary bounds four Degrees North Latitude ; and further, turns fo far South, that fome- times 'tis carried ftrait from that Point, fometimes alfo from the intermediate Points betwixt it and the Weft. When there- fore the Courfe muil be ileer- ed againll the Wind , if that be towards the South- Weft Point, they have a Wind that turns more and more to Eaft, as they retire from the Conti- nent of Africa ; but the Dan- ger is in paffing the Coaft of Brnftl, where Quickfands are fo frequent. But if they go towards South-Eaft, they mult of neceffity come near the Coaft of Guinea, from which they can't otherwife retire, than by failing towaids the Eaft as far as St 'Thomas'" s liund. 2. What all Ships loofing from Guinea to Europe, nccef- farily do for the Rcafon laid down in our Sixth Obfervation. For near the Shore blows the South-Weft Vv'iud, with which they can ne:tl;er fail, the land ly- ing in the way, nor go foagainft it, as to dired their Courfe north- ward to Europe. They fail tiien in a Courfe quite different from thatintended, 1//2;. either South, or to the Point next to South- eaftward. Following this Courfe they indeed retire from the Shore, but have the Wind more and more contrary, and are 0- bliged to fteer Itill more to the Eaft, 'till they make the L^and ot St Thomas, and the Lopejian Cape ; wherehnding a Windde- clining from South to Eaft, fail wefterly with it 'till they come to the fourth Degree of South Latitude, where they find a South -eaft Wind blowing per- petually. On Account of thefe conftant Winds, all Mariners who iail to America, or Virginia, firft fteer fouthward, that by the Affiftance of this conftant Eaft- Wind they may be cairied weft ward. For the fame Rea- fon, they who come from thofe Countries for Europe, directing their Courfe northward, endea- vour, as foon as poffible, to come at the thirtieth Degree of North Latitude. For here, firft, they find the Winds variable ; K. k 2 yet 500 The Abjolute Tart Sect. VI. Day. The ftated Winds are otherwife fubdivided, 'VIZ, Ibme when they begin to blow, continue for lome }'et more frequently blowing trom the SouLh-Welt Points. II. As in the Atlantic, fo in the Indian Ocean, the Winds are partly conftant, and partly p/eriodical ; that is, they blow for fix Months in one Point, and the fix following in the very oppofite Point. Both thefe Points, and the Seafons at which they turn to the oppofite Sides, differ with the Places. And tho' it be matter of great difficulty to obfcrve how the Trads of the Sea may be defined when fub- jed to each periodical Wind, or Monfoons as they call them : Yet liaving iifcd clofe Application, I don't fcniple believing the following Par- ticulars. 1 . Betwixt ten and thir- ty Degrees of South Latitude tliro' that Tra<5l of Sea bound- ed by St Lai'.rence\ Ifland and Ne^u Holland, the South-Eall Wind blows all the Year ; yet fo as to be fomewhat nearer the Eaft than South j jiill as a- bout the fame Latitude in the Atlantic Sea, we above Hiew'd them to be. 2. That South-Eafl Wind blows, from May to Noi;ember, to the fecond Degree from the Equator ; in which Month of No'vember, between the third and tenth Degrees of South La- titude, near that Meridian which paffes thro' the northern V\wX. of St Laurencth Ifland, as alfo between the fecond and twelfth Degree about Sumatra and Ja-va, arifes a Wind con- trary to the former, 'vi%. the North- Weft, which reigns the other fix Months ; 'viz. from Ko'vember to May. This AIo- tion of Winds is found to ex- tend to the Molucca Iflands. 3. Northward from the third Degreeof South Latitude, in all the Arabian or Indian Sea, and in the Bay of Betigal, from Su- matra as far as the Shore of A- frica, is obferved a Motion dif- fering from the former, breath- ing from the North-Eafl Cli- mates from Oitober to April, which for the next fix Months rifes from the oppofite, or South-Weft, Points. Then it breathes more violently, and brings Clouds and Rain ; but upon the blowing of the North- Eaft Wind the Heavens become fercne. But it is to be obfer- ved, that in the Bay of Ben- gal the Winds keep neither their Force nor their Points with the fame Conftancy, as in the /W//?//: Sea. Alfo the South- Weft Winds, near the African Shore, decline more fouthward ; near India, more weftward. 4. On the South of the E- quator, that Tracfl of Sea, which lies between Africa and Lau- rence Ifland, and which goes as far as the Equator, feems to appertain to the Motion of Winds jull now laid down. For in thefe Places the South-Weft Wind blows from Q^ober to Aprils C H A p. 2 1 . of Vniverfal Geography. 50 1 fome Months, fome for half a Year, fome for a Month, and fome for a few Days. AMONG j^pril, fomcwhvit nearer the South ; but fuch as fail to the North perceive it decline to- wards the Weft, which at length coincides with the periodical South-Weft Wind, which they fay blows at that Seafon of the Year, from the North Side of the Equator. But what Winds during the reft of the Yea-r, reign in that Sea, I cannot fuf- ficiently determine: becaufe our Sailors, in their return from India, fteer their Courfe be- yond the IHand of St Lau- rence. This only I could learn, that the Wind for the moft part comes from the eaftern Points, fometimes declining to the North, and at other times to the South. 5 . On the Eaft of Sumatra, and North of the Equator, as alfo on the Coafts of Camboia and C,6/«^, the periodical North- Eaft Winds come nearer to North, as do the South-Weft Winds to South. And this is ob- ferved to hold 'till you havegone beyond the Philippine Iflands on the Eaft, and as far as Ja- pan towards the North, In the Month OSlober, or November, a northerly Gale arifcs ; and in May a Ibutherly, which con- tinues from that time du- ring the whole Summer. But it is to be marked, that the Points of the Winds are not io fteadily fixed in thefe Parts, as they are in other Seas : fo that fometimes the South Winds de- cline a Point or two towards the Eaft, as the nortliern do towards the Weft : whicii feems to take it's rife from the Bulk of the Lands, that are every where interpofed in this Sea. 6. About the fame Longitude on the South of the Equator, ■viiz. in the intermediate Space between tlie Iftands Sumatra and J'a'Z'a lying to the Weft, and Ne-M Guinea to the Eaft, nearly the fame periodical Winds blow from the North or South ; b.it fo that the North Winds incline to the Weft, and the South to the Eaft. And thefe blow with the fame inconftan- cy and fliifting of the Point, as tiaofe of the Quarter above- mentioned ; but the Motions begin four or fix Weeks later than in that Sea. 7. The Change of thefe Mo- tions does not happen fuddcnly, or at once ; but in fome Places there are Calms, and in others changeable Wmds. And often on the Shore of Cormandel, towards the end of the acciden- tal Motion ; and the two laft Months there arifc furious Tem- pefts in the Chinefe Sea ; with the periodical Wind at South. All Navigation in neceflarily regulated according to thefe Winds ; for if Sailors fliould de- lay the Seafon 'till the contra- ry Motion begins, they muft either fail back, or go into Harbour, and wait for the re- turn of the Trade -Wind.

The third, or P^cifc Cceaii, llretches nearJy as far as tl.e two former taken toge- ther; viz. one hundred and fifty Degrees, from the weftern Shore of America to tl;e PhiHppine Ifles. But as this is failed by very few befides the Spaniards, from Spain to the Manilhas, and that only once a Year ; whilft th.y conftantly take the fame Courfe ; it remains in a great Meafure unknown to us ; and cannot therefore be defcri- bed with the fame exadnefs as the reft. Thus much is certain ; as well from the Obfervations of the Spaniards, as others, that the Winds which blow here have a gi eat affinity with thofe in the Atlantic ; for the North- Eaft blows to the Nortli of the Equator, and the South- Weft to the North of the fame, with fuch a Strength and Conftancy, that the vaft extent of this O- cean may be failed in about ten Weeks, without fhiftirg the Sails. Here alfo are no Tem- pefts, fo that failing is no where fo commodious, as neither Wind is wanted, nor it's Violence to be feared. Whence fome ima- gine, that it is as (liorta Voyage thro' the Streights of Magellan to China or Japan, as by doubling the Cape of Good- Hope. . Thefe Trade-Winds extend not to above thirty Degrees of Latitude on both Sides of the Equator, as in the Atlantic O- tean. This appears in part froiA the Courfe obferved by the Spa- niards returning from the Ma- nilhas to Neuo Spain ; fcr by means of the fjuthern Wind, which blows in thefe Iflands during the Summer Months, they fail to the South up to the Latitude of "Japan ; where they firft meet with various Winds that will carry them to the Eaft. And in part again, from the Oblcrvations of Schoo- tin and others, who failing to India thro' the Streights of Magellan, found almoft the fame Diftance of the Winds on the South of the Equator. And in this alfo the Winds of the Pacific agree with thofe of the Atla^iiic Ocean j that near the Coaft of Peru they approach to the South, as on the Coaft of Angola. That the Reader may form the better Notion, we ftiall add a Figure (fee Fig. 30.) re- prefenting to the Eye all the Quarters and Points of all the Winds. The Limits of each Traft are marked with pricked Lines, as well in the Atlantic, whether they fepa- rate the variable Winds from the cor.ftant, as in the Indian Ocean, where they alfofeparate the different Monfoons from one another. The eafieft way of marking the Quarters of the Winds feemed to be by a Se- ries of little ftiarp-headed Lines, pointing alternately to the Parts of the Horizon from whence the Winds blow. But as the Pacific C H A p. 2 r. of Vniverfal Geography. ^03 Sea ; and thefe fas alfo the times of their blow- ing) are called Monjoons j whicii are iouhu chief- Pacific Ocean is fo extreamly large, and yet in a great niea- fure unknown to u.s; 1 was un- willing to exhibit the whole, to prevent enl -rging the Map beyond a reafonaole lize. There ariles, from the Pre- mifes, various Queitions worthy the Coniideration of Philofo- phers : the principal are thefe. I . Why does the Wind in the Atlayitic and Pacific Ocean, continually blow from the Eall within thirty Degrees on both Sides the Equator ? 2. Why is not the like conflant Wind found beyond thefe Limits ? 3 . Why is the Weft Wind found perpetual near the Coait of Gui- nea? 4. Why, in the northern Part of the Indian Ocean, do the Winds for fix Months con- fpire with the aforefaid Winds; and for the other iix, blow from the oppoiite Point; whilft that part of the fame Ocean which lies on the South Side of the Equator, has no other Winds but what are found in other Seas ? 5. Why do the conftant Winds on the North Side of the Equator incline to the North ; and on the South Side to the South ; 6. Why in the Chinefie Sea, chiefly, is there fo remarkable an Inclina- tion of the Winds to the North ? For the folving of thefe Pro- blems, I offer the following Particulars to the Confideration of the Learned. Wind is properly defined a Current, or Motion of the Air, which if conftant, or perpetual, mult have a permanent or con- ftant Cauie. Some imagine this Caufe to be the aunual Revolution of the Earth about it's own Axis. This might periiaps be allowed, if ahnoft continual Calms were not found in the Atlantic Ocean near the Equator ; and alfo Well Wmds upon the Coaft of Guinea, and weftern Trade-V/inds in the In- dian Ocean, under the Equator. Befides, the Air being a ponde- rous or gravitating Body, it will acquire the fame Velocity as the Earth; and as it rolls along therewith in the annual Moti- on, it will feem more to do it in the diunr.l ; which is not above a thirtieth fo fwift as the other. So that fome other Caufe muft be fought for. The true Caufe wc judge to be the Sun continually permeat- ing the Ocean ; with the Ad- dition of t!ie Nature of the Soil and adjacent Country. For by the known Laws of of Hydroftarics, that part of the Air which is moft rarified by Heat, is the llghteft; and con- lequently the others tend to- wards it, 'till an /rquilihritan be obtained. But as the Sun con- tinually moves tov.-ards the Wert ; it is manifeft that the Air, moft heated by it's direft Rays, mult thus move the fame way ; and therefore the v/hole Mafs of the lower Air. By this Means there is produced a general Eaft Wind, which K k 4 putting 504 '^'^ Abjolute Fart S e c T. VI. ly in the Indian Ocean, from Africa to the Thi- lippne Ifles ; tho' in other Places they are not quite "wuhout putting all the Parts of the Air, refting upon the vaft Ocean into Motion, they all keep their own Motion 'till the Sun returns; whence the Eaft Wind becomes perpetual. And hence it follows, that the Wind on the North or South Side of the Equator, ought to incline towards the North or South. For as the Air ncnr the Equator receives the Sun's Rays perpendicularly, twice every Year, and never more inclined than thirty De- grees, it muft of courfe be greatly rarified by fo great a Heat. Near the Tropics alfo the Sun is vertical, for a confide- rable Time ; but as it is diflant therefrom forty-leven Degrees for no lefs a time ; the Air hence becomes fo cold that it cannot afterwards be brought to the fame Degree of Heat, which it receives under the Line. Whence the Air, being lefs rarified on both Sides the Equator, flows to the middle. And this Motion being com- pounded with the Eaft Wind abovementioned, explains all the Phsenomena of the general Winds ; which, if the Surface of the Earth was every where covered with Sea, would blow v/ith the fame conftancy they do in the Atlantic and Ethiopic Oceans. But as the Ocean is inter- rupted with fuch large Trafts of Land, regard muft be had to JhcNatureof the Soil, and the Pofition of high Mountains ; to which two Caufes the Changes of the Wind feem principally aftignable For when a Coun- try lying near the Equator is low and fandy, the Heat of the Sun, refleded by the Sand is fo great as to be almoft in- credible. And thus the Air of this Place being highly rari- fied ; the denier Parts of the Air will necefllirily move thi- ther to reftore the JEqidlibrium. Whence I judge, that near the Coaft of Guinea the Wind con- ftantly blows to the Land ; as it is e.xceeding probable that the inner Parts of Africa are violently heated : fmce even themoft northern Parts thereof, by reafon of their Heat, made the Antients believe ail the Parts beyond the Tropics uninhabi- table. And hence we may explain thofe freq'ient Calms; mention- ed above in our fixth Obferva- tion. For as that Part of the Atlantic lies betwixt the Weft Winds perceived near Guinea, and the conftant Eaft Wind that blows in the Parts fome- what more to the Weft, the Air lying thereon giving way to neither of thefe contrary Winds, keeps it's Place, and makes a Calm. And the Air not able to fupport the Vapours here plentifully raifed by the Heat, as being more light and rarified ; the oppofite Winds frequently caufe the Rains to fall heavy. AxA C H A p. 2 1 . of Umverfal Geography. 50 r wichout them ; the obferving of thofe times is ve- ry materia], when Sailors go to the fame Point, or above mentionttd of the inner Parts of Jfrica ; but wlien the Sun declines to tJie South they enjoy a temperate Air. But this is owing to the long Ridges of Mountains whofe 'J'ops be- ing generally covered with Snow in the Winter; this great- ly cools the Air. For this Rea- fon the general North^Eail Wind blowing in the hiiian Sea is at one time of the Year hotter, and at another colder than the Wind carried circularly from the South -Weft ; which is the hotteft of thefe contrary Winds ; when it blows thro' the upper Region of the Air; it follows that the under Courfe of the Air one vv'hile moves from the North -Eaft, another from the South-Weft ; from the later in the Summer, and from the former in Winter ; as we ob- ferved in explaining the Ph:£- nomena of the Trade-Winds. From the fame Caufeitfeems to proceed, that the North- Weft Wind fucceeds the South- Eaft in a certain Trad of the Indian Ocean, lying without the Equinottiaj, at the time that the Sun approaches tlic Tropic of Capricorn. But here we muft not con- ceal, that there is a great dif- ficulty in explaining the Reafon why in the fame Lati- tude of the Indian Ocean thcfc Winds are found, there is a per- petual Eaft Wind in the At- lantic without any Variation at all. It And hence it appears, that the Part of th.e Air rarified by Heat, being conftantlycomprel- fed on all Sides by the colder and denfer Air, that furrounds it, muft be continually driven upwards, as it were like a Va- pour, and be there every way equally difperfed to maintain the jEquilibrium ; fo that the upper Courfe or Motion of the Air ftiall be contrary the under. And thus, as it were by a cir- cular Motion, the conftant Winds that blow near the Earth , produce another Wind that blows a contrary way in the upper Regions of the Air. And this Conjedure is alfo in part confirmed by Experience. For when Sailors are got beyond the Limits of the Trade-Winds, they immediatly find a Wind blowing from the oppofite Quar- ter. And hence alfo we may eafily explain the Phaenomena of periodical Winds, or the re- turn of the Monfoons ; which as it fcarce admits of any other Solution, fo it confiderably con- firms our Hypothecs of the cir- cular Motion of the Air. Forfuppofing this circular Mo- tion of the Winds, we muft ob- ferve that the northern part of the Indian Ocean is every where interfperfed with Land, running out within the Limits of the periodical Winds, niiz.

Tho' they do hot immediately begin to blow the other way, when they have done blowing the former way j but after fome Days more, or lefs, in which the Winds are unfettled ; and the Sailor fometimes furprized with Calms \ and the Sea-Waves move fe- veral Ways •, yea, and frequent Storms arife. Some of the Monfoons return twice in a Year, but not with the fame Vehemence. I. I N that part of the Atlantic Ocean which lies in the Torrid Zone^ and that alfo in the Temperate^ the North Wind blows frequently in the Months of Oclober, November^ ancl January ; and thefe Months are the bed times to go trom Europe to India, that they may get beyond the Equator wirh the help of them ; for it hath been found, that fome Ships that had gone from Europe in March have not come fooner to Brafil than thofe that jeft it in Ocfoher ; coming both to it in the Month of February -, being helped by the North Winds. But becaufe this Wind is not fo conftant and certain, Seamen do not reckon it among the Mcn- foons. Nor is it eafy to give the caufe of that Wind in thefe Months ; except we refer them to the great quantity of thick Vapours at that time, or the conftant prefiure then made by the heavy Clouds. And they that wintered in Nova Zsmbla fay, there was a conftant North Wind all the Winter -, which could not be by a Rarefa6tion of the Air made by the Sun, v/hich was under the Horizon. Yet we It is alfo very difficult to ex- are found only in the northern plain why the Limits of the part of the Indian Ocean ; conftant Winds fcarce reach be- whiLI in the South part the- yond thirty Degrees of Lati- North-Eaft Wind perpetually tiide ; as alfo why Monfoons think C H A p. 2 1 . of Unherfal Geographv, coy think it may be maintained in the general, that moll of thefe Monfoons come from the melting of the Snow, or the clifTolution of the Clouds in the North and South Places, eipecially the Mountains which I am apt to believe, becaufe thefe Monfoons blow, for the moft part, from the North or South, or the Points collateral ; and becaufe the Snov/ and Clouds in the northern Parts are difTolved by the Sun •, efpecially in that half Year it goes thro' the North part of the Ecliptic, the Monjoom are then from the North, and in the other half from the South. THE Caufe of thefe Monfoons in the Sea, blow- ing moftly from collateral Points, as South-Eaft, North-Ealt, or thofe next them, feems to be from the different Situation of the Places in which the Snow and thick Clouds are -, or from the general Wind which may divert them to another Point : for that Wind blowing to the Wefl, and the Mon- j'oons tending North and South, they muft hinder one another \ and thus go in a Point between the Cardinals. But the South- Weft and North- Wefb Monfoons are rare and weak, and are fcarce to be reckoned Monfoons ^\^\\tvi the North and SouthWinds feem fometimes by accident to decline to the Weft, but are drawn to the Eaft by the general Winds. There are required for giving the Caufcs of the great variety of the Monfoons in different Places, more accurate Obfervations, not of one Year only, but of feveral Years j with the Times of the Winter, Rains, Snows, and of the Mountains in thofe Places from which the ftated Winds blow. We fliould alfo know the Motion and Age of the Moon ; which may caufe a Change in this Matter. 2. I N the Month of Jul^^ and fome Months near it, the South Winds blow at Cape Verd in Africa (when there is a Winter of Rain there) which feems 5o8 I'he Abfohite Fart Sect. VI. feems to be from the fame Caufs that makes the North Winds blow in Winter, in our Zone. 3. AT the Cape of Good-Hope the North-Eaft Wind blows in September. 4. AT Patanen (which is a Kingdom and a Town of the fame Name in India^ beyond the Mountains of the Gate) there are conftant Rains, and a North-Eaft Wind that blows ; but in the other Months an Eaft Wind blows thro', and 'tis Summer then. 5. ABOUT Sumatra the Change of the Adon- foom is in November and December. 6. I N the I (land of del Ma^o, one of the hit Ifles in the Azores^ there blows a vehement Wind in the end of Juguji from the South, with much Kain, which moiftens the Land, that is naturally dry, and then the Grafs begins to fpring up ; which fattens a great many Goats there, againfl: the end of December. 7. I N the Kingdom of CoNgo in Africa, from the middle of March to September \ when the Win- ter reigns there, the North, Weft, and North- Weft Winds blow, or others intermedite, which force the Clouds together on the Tops of the Moun- tains, and caufe a dark Air with Rain ('fee the next Propofition) : but from September to March the Winds are contrary, being South, Eaft, and South-Eaft, and others intermediate. We have taken thefe differences of the anniverfary and Jiated Winds from the Obfervations of Sailors, who call tlieni Monfoons when they blow for a great way on the Sea. We would now treat of their Caufes ; but we want to know the Mountains, Snows, and the Times of their dilTolving, and other things ; nor are the Obfervations of Sailors fo exadl as to de- ferve an accurate Enquiry into their Caufes. ^ THE Monfoons that are moft famous are; i.

BUT at the Shores, the eaftern Monfoon va- ries much ', fo that only from January to the end of March or the middle of May, the Ships that go to Perfia, Arabia, Mecca, and Africa, only fail when they come from India on this Side the Gate, or the Shore of Malabar ; for the Storms rage in the end of May, and all June, July, and Augufi, with a North Wind often, or a raging North-Eaft Wind ; therefore no Ships go from India on this Side the Gate in thefe Months. But on the Shore of India, beyond the Gate, or the Eaft Shore, or the Shore of Cormandel, they know nothing of thefe Storms. They fail in the Month of September from Ceylon and Java, and other Ifles there to the Molucca Ifles ; for then the Weft Monfoons begin, that hinder the general Eaft Wind : but when they come to the fifteenth Degree of South Latitude, from the Equator, the weftern Monfoon is fenfible in the Lidian Ocean, and a general South- Eaft Wind fills the Sails- 3. FROM Cochin to Malacca, i. e. from Weft to Eaft, they begin to fail in March 1, for then the Weft Monfoons begin there, or rather the North- Weft Wind blows often. 4. I N the Kingdom of Guzarat, i. e. in India on this Side of the Gate, the North- Weft Winds blow the half of the Year from March to Sep- tember, and the other half Year the South Winds, and that without much hindrance by other Winds. 3 5.

T H O' in the Indian Ocean, from January to June, the Monfoons are Eaft, and from Auguft to January Weft -, yet, in feveral Parts, when you are to fail from one Place to another, there are fome fet times that are counted beft ; becaufe the collateral Winds blow more or lefs at thofe times, or other Winds do more or lefs mix themfelves with thefe. Therefore they take one Monfoon when they are to fail from Cochin to Malacca •, and another when they are to go from Malacca to Maccou, a Port-Town in China •, and another when from Mciccou to Japan. 7. AT the Ifle of Banda the weftern Winds ceafe at the end of March ; and at the end of April the Winds are variable, and become calm on a fudden ; and in May the vehement Eaft Winds begin, with Rain. 8. AT the Ifle of Ceylon, near the Cape of Ponto- Gallo, on the fourteenth of March there is firft a weftern Wind, then a conftant South- Weft from the end of March to the firft of OUoher \ then the North-Eaft Wind begins, and blows to the middle of March: but fometimes the Monfoons come fooner or later by ten Days or more. 9. I N the Voyage from Mozambique, in Africa, to Goa, in India, the South Winds rule all the way to the Equator, in the Month of May and June, but from the Equator to Goa the South and South- Weft Winds prevail in the Months of July and Auguft, and the following Months. 10.

BUT when they fail from Japan to Maccou, i. e. from Eaft to Welt, in February and Marchy there is an Ealt and North- Eaft Wind ; but thcfe do not prevail on the Sea, but at the Shores of China % which they that fail from Japan find in their Voyage. 19. WHEN they fail from the Philippines^ or China f to Aquapulco^ a Port in New Spain, there is a Weft Wind in June, Ju^'jt and Augiijl -y tho' very weak, except at Full Moon -, but they are moftly Souch-Weft Winds. But they keep from the Tornd Zone near the northern Shores of Afnerica to fhun the general Eaft Wind, tho' 'tis but weak then -, for 'tis to be known in general, that the weftern Winds are more weak than theeaftern, becaufe the former are hindered, and the latter promoted by the general Wind. 20. 1 N the Sea of China the South and South- Weft Monfoon is in July, Augujl, and 05lober -, but thefe Winds turn to the Eaft: for they never turn immediately to the South, but firft they blow fomc Days to the Eaft, and then to the South ; tho' the North- Eaft Wind is fometimes changed, on a fudden, to the South-Weft, and fometimes from the North to the South immediately, which is very common here. T 11 U S the more conftant anniverfary Winds are found at Sea ; both thofe that are lefs conftant, and thofe alfo that are anniverfiry, as well on the Shore as Places near the Shores. PROPOSITION IV. The Etefian or anniverfary Winds in Greece, proceed from the Rains and Snows melted on the Mountains. THE Grecians obfcrved two Kinds of ftated Winds each Year, which they called Etefia: -, i. The Summer, C H A p. 2 I. of Ufiiverfal Geography. ^ \ ^ Summer, or Dog-winds^ which were called Etejix in general j becaule they were more ftrong and I'cn- fible. 2. The IVmter-lVindi, which they called Chs- lidonian or Ornithian. THE Etefian Dog-'windi are from the North, Writers differ about the time of their begin- ning. Arijlotle^ having told us they blow af- ter the Summer Solllice, adds nothing of the exa6\: time •, which was a great negled: : and the more becaufe when he fpoke of the Ornitbics he omitted both the time and the part they came from. Moreover, they who have marked the time of thefe Eteficdy have made their forerunners, which is about eight Days fooner, to begin when the Dog-Jlar rifeth, on the fixch, or fifteenth of July ; and to continue forty of the Dog-dap, and fo end with Augujl : tho' others extend them to the middle of September. They blow only in the Daytime : nor do they come early in the iVIorning -, which made the Seamen call them delicate and lazy. THE Caufe of thefe Winds is no doubt the melting of the Snow on the northern Mountains, by the Heat of the Sun, which is then at the greateft ; having for feveral Months fhone on thole Moun- tains, without fetting. And with this Caufe it a- grees well that they ceafe at Night ; becaufe then the melting ceafes, or is fmaller than to make a Wind, the Sun being then near or under the Horizon. THIS fame northerly Dog-'wind, not only in Greece^ but alfo in Tbracia, Macedonia^ the /Egean Sea, and it's Ifles, (which I know are fometimes all included in the Name of Greece) yea, in Egypt alfo, and Africa, and probably the lame that vv* fliid in the former Propofitions, did blow in the Kingdom of Congo^ beyond the Equator, between Mirch and September \ we fay the Hime Dog-wifid, ^c. are the fame with the Eteft^e of the GreciafUy or come from the fame Caufe. And likewife that VOL. I. LI North 5 1 4 ^he Ahjolute Fart S e c t . V I. North Wind which we faid blows in tlie kingdom of Guzarat^ from March to September^ proceeds from the melted Snow on the Mountains of /Ifia ; which they called the Sannatian Mountains, and the Earth's Belt ; and therefore we reckoned it among the Monfoom. THE fecond anniverHiry Wind of the Grecians ^ is the Chelidonian^ or the Bird^s Wind \ which they tell us began alter the W^ inter : but they do not tell us the Day when it began. Thefe are South Winds contrary to the Dog-winds^ very weak, and likewife inconftant, and of lefs Duration -, which makes the Sea pleadmt, and fignifies the coming of the Win- ter Birds, which they call Chelidom. Arijlotle fays they blow by turns to the middle of Summer, 'till the eafterly Winds, or Dog-ivinds^ from the North, begin, but very weakly. THEIR Caufe is alfo the melting of the Snow on the Mountains of the Moon in Mono- niotapay which are called fnowy by the Portuguefe : which Snow the Sun melts and rarifies the Air thereby \ becaufe 'tis Summer there, when 'tis Win- ter with us and in Greece ; the Sun then being in the South part of the Ecliptic. And this Wind is alfo found in the Kingdom, of Cor/go, in Egypt, and in the uEgean Sea ; and the like in Guzarat^ but for many more Months : for it begins in Congo and Cuzarat in September^ and blows 'till March. I T was the yearly Wind among the Grecians ; which they called Ornithias, or the Bird-Wind ; and they faid it continued after the vernal Equinox, while the Sun was mounting to our Zenith. PRO P OS I'TION V. Wh^ thefe 'Ext(\^.n Winds do not blow iu Italy, Ger- many, PrufTia, and other kingdofnsyfinci they are nearer the Mountains in the Norths from which the Etefian Winds of the Grecians hlowy as we faid. THIS C H A p. 2 r . of Ufiiverfdl Geography. 5 1 ^ THIS Queftion hath no Tmall difficulty in it ; and I could wifh to hive more accurate Oblcrva- tions o:; this Head, to determine what Winds then blow in tht leveral Places \ or if they return again each Year i lor I remember to have read, that in Aq^uitania^ a part of France, there is an anniver- fary Wind. BUT if any thing be faid to this Queftion, thefc Particulars feem proper •, i. In our Di:'^.D^v5 the North W^ind blows, which carnot be denied. 2. *T'is not fo conftant, nor doth it return every Year ; per- haps it may not be felt, becaufe of the frequent blow- ings of other Winds. 3. Itmight be fliid ; the Moun- tain whereon the Snow begins lirft to meJt, is fituated dire6lly towards Greece •, and therefore the firft Dog- JVind is carried thither •, and the Vapours from the Snow on the reft of the Mountain is carried thither •, becaufe they then find an open Paftage that way : but thefe extemporary Thoughts I fhall lay afide, io foon as I find better from better Obfer vat ions. PROPOSITION VI. Some IVindi are proper^ and almoji perpetual, to fome Place or Tra^ of the Earth, othen inconjiant. THERE are few Places where a Wind blows always •, the principal are thefe : viz, i. Places un- der the Torrid Zone, efpecially the Parts of the Pa- cific and Ethiopic Sea in that Zone have a perpetual Wind from the Eaft, or fome collateral Point, which we called. Prop. 11, a general Wind. And this Wind is not fo much to be termed proper as com- mon, or belonging to many Places ; for 'tis by ac- cident that 'tis not felt in all Places-, 'viz. becaufe other Winds blow more ftrongly. The Caufe of it is given in the forecited Place. 2. ON the Shores of the Kingdom of Peru and Parts of Chili, and the adjacent Places on the Sea, "LI 2 the 5 1 6 'Tbe Ahfolute Tart S e c t. VI. the Wind is almofl: perpetually South, or in fome collateral Point to the Weft. It begins at the forty fixth Degree of Latitude, and blows to Panama at the American Ifthmus, and makes the Siiips (load- ed with Gold and Silver) come from hima to Ma- nama, in a few Days •, tho' it takes a great many Days to return : but in Places remote from the Sea this Wind doth not blow. 'Tis hard to give the caufe of this Wind *, becaufe the South-Land, from which it fecms to blow, is not yet known to us ; yet I luppole there are found therein Moun- tains continually covered with Snow, from the conftant meltings whereof thefe Winds blow. But I would not here prepoffefs the Reader's Judg- ment with my Conjeftures. Perhaps the Snows that are found at the Streights of Magellan^ all the Year, are the Caufe of this Wind. But yet thefe Mountains lie from the South eaflward, and the Winds blow from a Point declining from the South weftward. Let us then leave this 'till we have a better knowledge of the South Continent. 3, AT the Shores of the Magellanic Land, or del Fuogo^ about the Streights of La Maire, there blow almoft conftant Weft Winds ftrongly ; fo that the Trees decline from a perpendicular to the Eaft. Nor is there any Place where thefe Weft: Winds blow fo much. But on the other Side of the Streights of La Maire, the South Wind blows on the Shores of the South Land. I can give no other reafon for it than the melting of the Snow, and the breaking of the Clouds in the South Land ; which extends itfelf on the Weft Side of that Streight, from South to North. Thefe Things are doubtful, and to be more diligently enquired into. •r 4. ON the Shore of Malabar, in Ltdia, the North and North- Weft Wind blows almoft the whole Year. The Caufe is the melting of the Snow on the Mountains of Sarmatia. in /ifia^ as thofe of C H A p. 2 I . of JJniverfal Geography. 5 1 7 of" Imaus, Caucafus^ or from the Clouds on otacf Mountains in /Jfia that prefs the Air below. 5. ON the Sea, nQ2LT Guinea^ the North-Weft Wind blows frequently ; but further off the North- Eaft Wind blows. 6. HALF way between Japan and Liampo^ a Sea-Port Town in China, the Weft Winds blow ail the way to Japan •, thefc blow there in November and December. 7. A T the Idand Guoton, not far from the IQand dos Cavallos, the South Wind is frequent on the Chinefe Sea •, whilft on the adjacent Seas the North Wind rages. PROPOSITION VIL Thofe JVinds that blow for fome Hours ever^ D^y-» ^f^ form Places, at a certain Time of the 7'ear, belong to the -periodical or fated IFinds. THEY are found to be twofold -, but only in fome Places near the Sea. Some blow from the in- land Parts to the Sea ; others again from the Sea to the Land : the former is called a Land- Wind, the latter a Sea- Wind. I. ON the Malabar Shore in the Summer-time, from September to April, the Land-Winds blow from twelve at Night to twelve at Noon, which are Eaft Winds •, Ror are they fenfible beyond ten Miles on the Sea -, and from twelve at Day to twelve at Night the Sea- Wind blows from the Weft, but fo weakly that Ships have little Benefit from it. The former Eaft Winds I fuppofe come partly from the general Wind, and partly from the Clouds on the Mountains of the Gate : but the Caufe of the latter is the diffolving of the Clouds by the weftern Sun -, which Clouds were forced together by the Eaft Winds. Thefe are my ConjecT:ures j but in other Months the North W^ind rages there, as alio L i 3 the 5 1 8 I'he Ahjolute Fart S e c T. VI. the Eaft, North-Eaft ; nor are the gentle Land and Sea-Winds fcnfible there, lor the frequent Storms. 2. AT th^ T own oi' Mafidipa I a}i^ on the Shore of Coromandel^ the Land-Winds be^in to blow on the firft Day of June ; they lad only fourteen Days, and then it is the Ships go from thence. But thefe are rather to be referred to the Mon- foom i for fo far as 1 underftand from Sailors Ac- counts, the Land- Winds are conftant on thofeDays j, nor do the Sea- Winds come after them. 3« GN the American Shpre oi^ New- Spain the Land- Winds blow to the Pacific Sea at twelve at Night -, but the Sea- Winds in the Day. 4. I N the Kingdom of Congo, and the Provinces of Lopo Confaho, the Land-Winds blow from the Evening to the Morning, when the Sea-Winds bt'gin to blow and mitigate the Heat of the Day. 5. A S to the Eaft Winds which blow before and at Sun-rifing, every Day, in all Places, efpecially at Sea, when other Winds blpw not, particularly in Brafil where they blow every Day in the Morn- ing ; the Caufe is plain : for either they are a Part of the general Wind, or elfe the Sun rarifies the grofs Particles of the Air that were condenfed by Night. 6. THE Etefian Winds of the Grecians, or their Chelidonian Winds, come among thefe ^(o- tidian Winds. 7. O N the Shore of Camhaya a Varella, at Pulo- Catte, the Land and Sea- Breezes fucceed one ano- ther daily, from the twenty- eighth of July to the fourth of Augujt •, for then the Monfoom ceafe, and there is a perfeft Calm for a while. The j^and- Breezes are from the Weft and North- Weft. But the Sea-Breezes are from the Eaft, and the collateral Points which turn to the North ; and dien turn back to the South » when *cis calm 'till the / Land ; C H A p. 2 1 . of Umverfal Geography. 5 1 9 Land-Breezes come, which are not iek on the Se;i above two Miles from the Shore. Thel'e Land and Sea-Breezes are aifo found at Havanua in America. PROPOSITION VIIL ^e nearer ive come to the Equator from the Ar5fic Pole, the northern IVinds are the zveaker ; and be- yond the Equator the South IVinds are Jlrong, and cold and dry, efpecially in Chili and Peru. THE Caufe of both is the fame : becaufe they come from the northern and fouthern Places : yet there are found South Winds in the northern, and North Winds in the fouthern Parts. PROPOSITION IX. It appears from what hath been faid, that there are four different kinds of IVinds. 1. THE Common, which blow in all Places, and all times ; except hindered by others, as the General one. 2. THE Proper, or fuch as blow at all times, but only in a certain Place or Tra6t of the Earth, 3. THOSE which blow in feveral Places, but not at all Times, as the Monfoons, or ^loiidian Winds. 4. THOSE which blow neither at all Times, nor in very many Places. PROPOSITION X. Some JVinds are fudden, andjlrong, but do not laft long ; fuch are Hurricanes., with, and without Lightening ; Whirlwinds, Storm from the IVater, and frotn the Air. Thefe are in fome Places anniverfary : and fome are only frequent in certain Places at Sea. THE Wind called Pr^7?fr ; is a ftrongWind that breaks out with Lightening and Flame. Such L I 4 ^"^^^^^ *- 520 ■ lie Abjolute Fart Sect. VI, ^eldom happen, and fcarce without the Ecnephia ; Seneca calls Prejler a Whirlwind with Lightening. THE Ecnephia is a ftrong and fudden Wind that breaks out from fomc Cloud ; which is frequent in the Ethiopic Sea, between B^afil and South A- frica •, efpecially at the Cape of Good-Hope, and on the other Side of Jfrica, at Terra de Natal, and 2X Guinea, under the Equator. Tho. Portuguefe q?A\ them Travados, the Latins Procella, but the Greek W^ord Ecnephia is beft : they are moft frequent in certain Places, and in certain Months of the Year. A little Cloud, and fometimes feveral of theni bl^ck or blackifh, are plainly feen by Sailors tq go together, and increafe even in a clear Sky, be- tore the Wind breaks out -, ar.d when they firft fee them, they lliould gather in their Sails, and prepare their Ship againft the raging Wind that is at hand ; but before the Portuguefe knew this Prognoftic of Wind they loft feveral Ships, being the firif that had failed the Ethiopic Ocean. For w:hen India was made known by Gamma, the King of Portugal {tut a greater Fleet of Ships, of large Bottoms, to the Number of thirteen, under Caprali in the Year 1500; which* was the firft Fleet fent to Brafil, with great Joy to the Portuguefe. WHEN they had waited there the Month of April, they failed in Maj towards the Cape of Good-Hope, with raging Storms •, and tho' they faw the Signs tliereof, yet they knew not the Tempeft that was to follow -, which Maffcus thus defcribcs. ' THEY made a long Run of almoft two ' hundred Leagues from Brafil towards the Cape * ('which is about one thoufand German Miles) the * Ocean and Winds all the wh^le raging. FJii,ving ' entered that Voyage in Maj, with more Bold- * nefs than Succefs, a fiery Comet appeared con- " tinually to the tenth Day, with a fearful Afpe6t ; ^ and the Sea and Heavens often changing ; the ' black Chap. 21. ofXJniverfal Geography. 52 1 * black and foul Clouds having gathered together * in the North into a round Form, and the Wind ' feeming to come all againft them as it were by * Reflexion: the Sea being faint in deceitful Calms. ' The Sailors not knowing the Tempefts that ufed ' to rage there, fpread their Sails to gather the ' Wind •, when on a fudden the W'ind broke out ^ from the Clouds in the North on four Ships ' whofe Tackling was not in order to be handed, ' and overfet them in a Moment ; and tho* the reft ' were looking on, yet not one of a great many * could be faved from death, except a few that ' had Oars or broken Pieces of Sails thrown to ' them. The North Wind continuing, the Sea •^ rofe fometimes high as it were to the Stars ; and ' again fell low to the Bottom ; the Sea looked * black in the Day-time, and fiery in the Night, * which Storm held them twenty D.iys/ So far Maffeus. THE Cape of Gcod-^Hope is difaftrous for fuch Storms from the Clouds. NOT far from the Shore there is a high Mountain, broad on the Top like a Table, from which great Storms often proceed -, and this prog- nofticates ftrangely. For when the Sky is clear, and the Sea fmooth, there is a little Cloud feen on the Top of the Hill, which appears at firft no larger than a Hazel Nut, and tb.en like a Walnut which the Duuh call the Ox-eye y and then covers the whole Plain above, and the Dutch compare it to a Table fpread wit.h all kinds of Meat on it : then the Storms begin to blow from the Top of the Mountain with fuch Force that overwhelms all Ships that are not on their Guard, or have their Sails out ; but Sailors are now more wary, and when they fee the Ox-eye, they run immedi- ately from the Shore as much as they can, and ga* ther in their Sails, and do what is proper i;o de- knd 522 The Ahfiliite Fart Sect. VI^ lend their Ships : nor does this Sign ever fail. The like S[orm rages at "^erra - I^latal^ having ti:ke Ox-e^e there alio \ and by v.. feveral Ships have been loft •, and likewil'e in th- -vhole Trad, between that and the Cape of Good-Hope. There is alfo in Dauph'nd m France^ nor f r ficm Vicnne^ a high Mouniain, on whofe T^p there is a Lake, from which all the Srorms thereabouts arife ; on the Top of it there is a little Cloud or Exhalation, which portends Thunder and Rain. O N the Sea under the Equator, between Ame- rica and Africay and near the Equator j there are irequently fuch Siorms-, efpecially in thofe Mondis in which there are few or no conliant Winds blow- ing -, and that almoft thro' the whole Year, efpe- cially in Aprily May^ and June, (in otlicr Months, *tis more rare) and they are very remarkable on the Shores of Guinea. They break forth three or four limes in, a Day, and ceafe on a fudden, varying ordi- narily every half Hour ; but they are moft vehement at firft. They break out from the black and filthy Clouds that appear when the Sky is clear and the Sea calm, by which the Seamen know they are approach- ing. And with their help it is that Sailors get beyond the Equator ; for other conftant Winds are often wanting, efpecially in thofe three Months, for they do not hinder the Ships failing except at the firft breaking out. B U T in that part of the Sea which is next the Kingdom of Loango^ in Africa^ the Storm is often in the Months of January^ February., Mareh, Aprils and in different Places of Africa at other times. THUS like wife at a Promontory in Africa^ called now Guardafu, not far from the Mouth of the Red-^ Sea, there rages in the Month of May every Year a North Wind, and the Ecnephias moft vehemently. FOR 'tis obfervable, that as fome Winds lefs fcircible blow yearly s fo there are Storms and Tem- 3 pefts C H A p. 2 1 . of JJnherfal Geography, pefts anniverfary in fome Places : and with iuch a Storm, not far from that Cape, did Sodreus, the Portuguefe Conful, perifh in the Year 1505 •, and tho* he was ddmoniflied by the Africans^ yet he would not hearken to it. BUT in the Entrance of the /fr^^w« Gulph, and in AraVia^ and Ethiopia, there is a peculiar and wonderful Storm happens. A thick black Cloud, mixed with fiery little Clouds (which are terrible to behold j, brings Darknefs in the Day, and on a fudden there breaks out a Storm, which is foon over ; but it throws fuch a quantity of red Sand on the Land and Sea, that the Arabians fay it fometimes buries whole Companies of Merchants and Travellers, with their Camels, viz. the Caravans that pafs there once or twice a Year, being gathered (out of all parts of Afia) in 5)n^, they arrive thence from Aleppo to Arabia^ to the Number of fix thoufand Men, who dare not travel by themfelves, becaule of the Rob- beries by the Arabians, and other Dangers, as they do from India to China and Tartary : and from hence 'tis they fay the Arabian and Egyptian Mum- my comes ; their Bbdies being dried in the Sand with the Sun's Heat. This Storm comes from the North to which the Red-Sea is extended ; and there- fore 'tis likely, there being a great quantity of red Sand on that Shore, that 'tis carried up by the Wind, which caufes a red Colour to appear among the Clouds, and afterwards talis down. AND 'tis alfo probable, that there is fuch a Storm of Sand in Libya, becaufe of the great Heaps of that Sand there ; which the Antients knew when they wrote of the difficult accefs to the Temple of Jupiter Hammon in Uhya : nor were they without the knowledge of the way how Mummy was made. In Guzarai, a Kingdom in /«^7,3, Clouds of Sand, or a vaft quantity of fmall Dull raifed by the Sun's Heat, 524 TJje Abfolute Part Sect. VI. Heat, doth often opprefs Travellers j as is written by 'Tivift a Dutchman^ who lived long there, A S to the Caufe of thefe Storms, 'tis plain they come trom the Clouds, and may be formed two ways. f. If a Cloud falls down, by it's Weight it will move the Air under it, as a Sheet, or Sail, let flill ; and hence 'tis the fmaller the Cloud appears the Storm after it is the greater •, for the Cloud, or Ox- ey^ is then high, and appears fmall, and falling down, moves the Air with greater force. 2. If ful- phureoiis Spirits inclofed in the Cloud, break out on a fudden in one Place, other Parts being fhut as the Wind breaks out of a Bottle, when the Liquor in it is heated ; but the firft Caufe feems the truer. PROPOSITION XT. Exhydrias is a Wind that breaks out of a Cloud with a great quantity of Water. THIS differs but little from an Ecnephias-, on- ly the Cloud, from which it feems to break out, is now condenfed to Water, and born up fo long by the Clouds about it, and perhaps forced together by the Winds, 'till at laft it falls down, and beats the Air below it, which caufes the Wind : but thefe are rare, and the Ecnephias itfelf hath often Showers attending it, and therefore the Difference is only in Degree -, except that the Exhydrias for the moll part comes ftrait down. PROP O S Il'ION XIL J Typhon is aflrongfwift Wind that blows from all Points^ wandring about all quarters, and generally comes from above. THIS is frequent in the Oriental Sea, efpecially in the Sea at Siam^ Cbina^ Rndjapan, and between Ma* ,^:(a and Japan. It breaks out violently almoft from the C H A p. 2 1 . of U?iiverjal Geography. r 2 - the weftern Point, and turning round the Horizon with a rapid Force performs the Revolution in twen- ty Hours; ftill growing ftronger and ftrongcr ; raifing thole Seas with it's ftrong whirHng about, to a great Height, every tenth Wave rifing above the relt, which dafhing againft one another with great force, the Seamen lofe all hopes of their Lives •, for which, and other Storms, failing from India to Japan is very dangerous j fo that if one Ship of three get fafe there, 'tis counted to be a profperous Voyage, The Typhon rages moft in Summer, and more than can be conceived by thofe who have not feen it •, fo that 'tis no wonder the Ribs of the ftrongeft and largeft Ships fhould be loofened : you would think the Hea- vens and Earth were turned to their antient Chaos. I T rages not only at Sea, but on Land, and over- turns Houfes, and pulls up Trees by the Roots, and carries great Ships a quarter of a Mile from the Sea. I T feldom lafts above fix Hours. In the Indian Ocean the Sea is at firft plain : but there come after- wards dreadful Waves. Thus about the Town of ^rbeil in Perfta, in the Months of June and July^ k raifes a great deal of Duft every Day at twelve of the Clock -, and lafts one Hour. THE Caufeofit, no doubt, is that the Wind rufh- ing to a certain Point, isobftrucfted, and returns on it felf, and is thus turned round, as we fee in W^attr that turns round about in a Vortex, when it meets v/ith an Obftacle ; or it may come from furious Winds meeting one another, which renders the Sea plain, and dafhes againft the Ships between them. If this Wind blow from above, 'tis called Cata-gis. PROPOSITION XIIL Whether fome Winds came from the Earth, either frojn the Land or IFater. W E think this is very cafy to conceive ; for fee- ing there are in the -Earth, and at the Sea Bottom, fe- vera 526 l^he AhjUute Fart Sect. VI. veral Cavities ; there may be in them fulphureous Spirits, which may break out violently, efpecially if a little hindered at firft : and if much hindered this caufes an Earthquake, *till at laft they make way for themfelves. Thus in the Maurice Ifies there of- ten breaks out a Smoak from the Earth ; and alfo from fome Caverns. In Japan there is a Fountain that breaks out at certain Hours of the Day, with sreat Force and Noife. BUT I do not remember to have read of any Wind coming out of the Sea. PROPOSITION XIV. Whether afr^ Wind arifafrom the Tides, or the flowing of Rivers. EXPERIENCE teftifies, that in thofe Places where the Tides are fenfible, when the Sea flows, the Wind doth for the moll part blow from the Sea, when other Winds ceafe •, and therefore it feems the Air that is contiguous to the Water flows with it to the fame Point : but 'tis to be confidered, whether that happens confl:antly. And I believe there may be another caufe given of that Wind, viz. That the Air is driven from it*s Place by the Water that flows in on the Land : for a fmall matter moves the Air •, and thus *tis thought the Air moves with the Rivers that run fwiftly, as the Zaire and Rhine. PROPOSITION XV. Why the fiery Appearances Ca^ov^ Pollux, and Hek- na, and what they call Jack in the Lantern, ap- pear amidfl Storms. NOT one, but a great many, are feen on the Mails of Ships, wandring with an uncertain Motion, tho* they leem fometimes to cleave ciole to the Sails and Malls •, but they frequently leap up and down, with intermifTion, affording an oblcure Flame, like that Chap. 21. of U?nverfal Geography. 527 that of a Candle burning faintly. If five of them are feen together, which the Portuguefe call the Virgin Marfs Crowny they take it for a iure Sign of the Storm being foon over. Their Caufe is fome fulphu- reous and bituminous Matter beat down by the Mo- tion of the Air above, and gathering together is kind- led by the Agitation of the Air; as Butter is gathered together by the Agitation of the Cream. And from this Appearance we gather, that thefe Storms come from fuiphureous Spirits that rarify the Air, and put it into a Motion. PROPOSITION XVI. IVhy Calms are fo frequent in the Sea near Guinea, and under the Equator ^ in the Atlantic Ocean between America and Africa. THIS is a Phaenomenon concerning the Winds, of no fmall difficulty ; that at Guinea^ which is two Degrees from the Equator, and under the Equator itfelf, there Ihould be almoft a conftant Calm, eipe- cially in April^ Ma-^^ and June^ where there are no Monfoons, and when the like is not found in otliQr Places fituated under the Equator. There is in- deed an Ecnephias pretty frequent there fometimes 5 and is defired by Seamen, becaufe by the fcelp there- of they get beyond the Equator : for fometimes go- ing from Europe to India^ they are kept a whole Month under the Equator : but they take care to keep from the Coafl of Guinea ; and without lofs of time fail towards the Coaft of Brazil, to avoid being be- calmed ; which hath kept fome Ships three Months near the Shore. I have not yet found the reafon of ic, except it may be faid, that there is no Snow found on the Mountains of Africa, between Guinea and Barbary ; which may caufe a conflant Wind.
