Its object is, to observe and classify the various appearances of nature, as they present themselves spontaneously, while undisturbed by the intervention of human art. Thej general phe- nomena of the universe, the wonders of the heavens, the form and structure of the earth, animals, vegeta- bles, fossils, and inanimate bodies of all species, fall, therefore, under its observation. Whatever can be dis- covered of any of these, by an attentive survey ; or by carefully watching those changes to which they are naturally subject, is recorded by the naturalist, in order that it may be added to the materials of some other science or some art, or that it enlarge the gene- ral experience of mankind. Although thus important, thu* extensive, and thus generally interesting, it was late in the progress of knowledge, before natural history assumed a regular form, or began to be cultivated as a distinct branch of science. Many theories of the earth and heavens had been imagined ; the science of ethics had been success-* fully cultivated in all its different branches ; the most important theorems in mathematics had been demon- strated, and the most intricate problems solved ; when Aristotle, the father of natural history, first attempted to collect a body of facts belonging to this department of knowledge, and to arrange them in scientific order. Taste and genius had passed their meridian at Rome, Vel I. A3 ir PREFACE. •when the elder Pliny collected that medley of science and fable, which is the only valuable work upon na- tural history that the remains of Roman literature afford. And, in modern times, the great masters of Almost every other science had passed, before Buffon and Linnaeus appeared. But if natural history did not, till a late period, be- gin to assume a regular form, or to command the atten- tion of the votaries of knowledge ; it has at length become a favourite study with almost all classes of men. The philosopher finds no task more pleasing, than to watch and compare the habits and manners of plants and animals. The virtuoso rejoices in the possession of a shell, a skeleton, or a stuifed skin, no less than in a rusty medal, a faded picture, or a mutilated statue. The painter and the engraver have exhibited some of the finest specimens of their respective arts in imitating the forms and colours of birds and quadrupeds. And what a numerous train of writers have lately sought fame or emolument, by illustrating subjects of natural history ! Linnaeus and Buffon, the chief of these last, have equally displayed, in their works, some of the highest efforts of genius ; although differing as much in their views, and manner of composition, as is possible for two able writers, upon the same train of subjects. The one has reduced natural history to the austere regularity of scientific method: while the other has displayed its materials in a loose order, and arrayed them in all the pomp of popular eloquence. The one has formed a new classification, and invented a new sys- tem of technical language, as apparatus for his favourite science : the other, in compiance with the taste of his eountiy;and the turn of hisown genius, has endeavoured PREFACE. r to strip natural history of \vhateverisreinote from popu- lar expression and popular ideas, and to teach her those blandishments, which invite and insinuate, and attract the notice, and even the regard of the gay, the careless, and the indolent. Buflbn, like most other eminent philosophers of France, intermixes ill-founded, and fantastic theory, in a large proportion, v. ith extensive and enlightened views of nature, and the most beauti- ful delineations of facts. Linnaeus seems to have pro- posed to himself to form simply an index to these parts of the volume of creation which are open to hu- man view. Both are eminently eloquent ; but the eloquence of Buffon is copious, diffusive, and often declamatory and redundant : while Linnaeus is re- markably concise and energetic. Yet whatever may be their comparative merits, Buffon will long continue one of the most popular writers on scientific subjects : but, it is not probable, that the volumes of Linnaeus will ever be fondly perused by any but men of science. These views of the importance and extent of natu- ral history, of the ardour with which it is, at present, cultivated, and of the character of the most popular of the capital writers upon the science, first suggested the idea of the PRESENT ABRIDGMENT. It seemed pro- bable, that the work of Buflfon might become still more popuLir, and of consequence, more generally useful, if it could be reduced to a less bulky and less expen- sive form. It was natural to observe, that of those who are desirous of acquiring some knowledge of na- tural history, or of amusing themselves with the con- templation of the objects which it presents, many are unwilling to be detained by theory, however plausible, to listen to amplifying declamation, or tc perplex them-- Ti PREFACE. selves with examining authorities, or balancing the evi- dence on the different sides of disputed facts. To the young it is peculiarly proper to recommend the study of natural history ; and nothing but a detail of inter- esting facts, in easy, correct, and perspicuous language, can be put, with any prospect of utility, into their hands. The compiler of this Abridgment has been guided by these considerations in the performance of his task, He has rejected, as far as was practicable, without destroying the contexture of the work, all such of Buf- fon's theories as appeared to him plainly ill-founded and fanciful : he has left out that display of authori- ties which Buffon had not always confined to his notes, but frequently introduced into the text : and he has often condensed his author's diffuse descriptions of the forms and manners of animals, and abbreviated his narrative of historical facts relative to them. He has at the same time anxiously endeavoured to make this Abridgment, a regular work, having consistency and connexion through all its parts, not an awkward heap of incoherent fragments. In the latter part, some ad- ditions are introduced from other writers, and to the whole is subjoined the NATURAL HISTORY OF INSECTS, compiled chiefly from Srvammerdam, Brookes, and Goldsmith ; and intended as a suitable companion to the present Abridgment of BufFon'u Work. CHAP. I. OF THE EARTH — ITS FORM AXD COMPOSITION—OF AT- TRACTION REPULSION ELEMENTS HEAT AIR — WATER. 1 HE figure of the earth, its motions, or the external relations which subsist between it and the other parts of the universe, belong not to our present inquiry. It is .the internal structure of the globe, its form and manner of existence, that we here "propose to examine. The general history of the earth ought to precede that of its productions. Details of particular facts relating to the economy *and manners of animals, or to the culture and vegetation of plants, are not, perhaps, so much the objects of natural history, as general deduc- tions from the observations that have been made upon the different materials of which the earth itself is com- posed ; as its heights, depths, and inequalities ; the motions of the sea, the direction of mountains, the si- tuation of rocks and quarries, the rapidity and effects of currents in the occean, &c. This is the history of nature at large, and of her principal operations, by which other inferior or less general eifect is produced. The theory of these effects constitutes what may be called the primary science, upon which a precise knowledge of particular appearances, as well as of ter- restrial substances, solelv depends. Vol. I. A 10 NATURAL HISTORY. With regard to the history of the earth, therefore, we shall begin with such facts as have been universal- ly acknowledged in al! ages, not omitting those addition- al truths that have fallen within our own observation. The surface of this globe presents us with heights, depths, plains, seas, marshes, rivers, caverns, gulf's, volcanoes, in the disposition of which, upon a slight view, we observe neither regularity nor order. If we penetrate into the bowels of the earth, we discover metals, minerals, stones, bitumens, and, in short mat- ter of every kind as it were without any apparent de- sign. Upon a more accurate inspection we perceive matter in every form, blended in a chaos of confu- sion, which can be compared to nothing but the ruins of a world. Amid these ruins, however, the different generations of animals, and of vegetables, succeed each other in a beautiful and regular order. With respect to us, the earth, formerly a chaos, is now become a delightful habitation, where every object aifords amazing displays of the power, of the intelligence, and of the bene- ficence of its great Creator. Astronomers tell us, that this earth which we inha- bit forms but a very minute part in that great assem- blage of bodies of which the world is composed. It is a million of times less than the sun, by which it is en- lightened. The planets also, which, like it, are sub- ordinate to the sun's influence, exceed the earth one thousand times in magnitude. These have been dis- covered as forming, with our earth, a system of bodies circulating round the sun, all obedient to one law, and impelled by one common influence. Modern philosophy has taught us to believe, that, when the great Author of Nature began the work of KATURAL HISTORY. H creation, he choose to operate by second causes ; and that, suspending the constant exertion of his power, he endued matter with a quality, by which the universal economy of nature might be continued without his immediate assistance. This quality is called attraction; a sort of approximating influence, which all bodies, whether terrestrial or celestial, are found to possess ; and which in all increase's as the quantity of matter in each increases. The sun, by far the greatest body in our system, is, of consequence, possessed of much the greatest share of this attracting power ; and all the planets, of which our earth is one, are, of course en- tirely subject to its superior influence. Were this power, therefore, left uncontrouled by any other, the sun must quickly have attracted all the bodies of our celestial system to itself ; but it is equally counteracted by another power of equal efficacy ; namely, a pro- gressive force which each planet received when it wras impelled forward by the divine Architect upon Us first formation. The''heavenly bodies of our system being thus acted upon by two opposing powers; namely, by that of attraction, which draws them towards the sun ; and that of impulsion, which drives them straight for- Wtird into the great void of space ; they pursue a track between these contrary directions: and each like a stone whirled about in a sling, obeying two opposite forces', circulates round its great centre of heat ai:d motion. In this manner, therefore, is the haimonyofour planetary sysU-rn preserved. The sun, in the mitlsf, es heat, and light, and circular motion to the phi- nets which surround it. Though we see the greatness and wisdom of the Deity in al! those worlds around us it is our chief concern to trace Him in that which WK iniu'bit. 4S NATURAL HISTORY. In examining and describing the surface of the earth the first object which solicits our attention is that body of water with which the greater part of the globe is covered. The waters occupy the lower grounds, and notwithstanding their uniform tendency to rest, they are kept in continual agitation by an agent, that com- municates to them a regular periodic motion, which produces a vibration, even to the most profound depths in the whole mass. When we explore the bottom of the sea, we discover hills and valleys, plains and hollows, and rocks and earths of every sort. We discover too that islands are only the summits of vast mountains ; we likewise find other mountains whose tops almost reach the sur- face of the wrater ; and rapid currents which counter- act the general movement ; and of which the motion is sometimes in the same direction, and at other times retrograde. On the one hand, we meet with tempestu- ous regions, where the heavens and the ocean seem equally confounded in the general shock ; violent in- testine emotions, tumultuous swellings, water-spouts, and strange convulsions produced by volcanoes, and dreadful whirl-pools. On the other hand, we discover vast regions always calm, but equally dangerous to the mariner. In short, when we direct our eyes to- wards the polar regions, we perceive huge masses of ice, which having detached themselves from them, ad- vance, like floating mountains, till they dissolve in the temperate climates. Besides tl>ese grand objects, the ocean exhibits an infinite variety of animated beings ; all of which find abundance of food in this fluid element. But when we take a view of the land, what differ- ences tajce place in different climates ! what a variety NATURAL HISTORY. is of soils ! what inequalities in the surface ! Yet upon an attentive observation, we* observe that the great chains of mountains lie nearer the equator than the poles ; that, in the old Continent, their direction is more from east to west than from north to south. And the figure and direction of these mountains which appear most irregular, correspond so, that the promi- nent angles of one mountain are constantly opposite to the concave angles of the neighbouring mountain, and of equal dimensions, whether they be separated by an extensive plain or a small valley. I have remarked that the opposite are almost always of the same height ; and that mountains for the most part occupy the mid- dle of continents, islands, and promontories, and that they divide them by their greatest lengths. By trac- ing the courses of the principal rivers, I find that their direction is nearly perpendicular to the sea-coasts in- to which they empty themselves, and that for the greater part of their courses they follow the direction of the mountains from which they take their rise. The sea-coasts are generally bordered with earth and sand accumulated by the waters of the sea, or swept down by rivers. In opposite coast?, separated only by small arms of the sea, the different strata are of the same materials. Volcanoes never exist but in high mountains ; a great number of them are entirely extinguished ; some are connected with others by sub- terraneous passages, and their eruptions pretty fre- quently happen -at the same time. Similar communi- cations subsist between certain lakes an 1 seas. Some rivers disappear on a sudden and seem to precipitate themselves into the bowe!s^£ the earth. Certain in- land seas, too, constantly receive from many rivers prodigious quantities of water, and .-which, as their 14 NATURAL HISTORY. bounds are not augmented, probably discharge thos« extraneous supplies by subterraneous passages. Coun-p tries that have long been inhabited may likewise be easily distinguished from those where the earth ap- pears in a rude state, where the rivers are full of ca- taracts, where the land is either almost overflowed with water, or scorched with drought, and where every- place where a tree can grow is covered with wood. In bur examination of the upper stratum of the earth, we find it to be universally the same substance which substance is nothing else than a composition of the decayed parts of animal and vegetable bodies. Penetrating a little deeper, we discover the real earth, beds of sand, lime, stone clay, shells, marble, gravel, chalk, &c. These strata are always parallel to ore another, and of the same thickness throughout. In neighbouring hills, strata of the same materials are uniformly divided by perpendicular fissures. Shells, skeletons of fishes, marine plants, &c. perfectly similar to those of the ocean, are often found in the bowels of the earth, and on the tops of mountains at very great distances from the sea. Petrified shells are found al- most every where in prodigious quantities, not only in- closed in rocks of marble and limestone, in earths and in clays, but incorporated and filled with the very sul - stances in which they are inclosed. Indeed all ir.a:- bles, lime-stones, chalks, marles, chiys, sands, and al- most all terrestrial substances, are full of shells and other spoils of the ocean. • From these facts, let us try what conclusions can IK drawn. The changes which the earth has undergone for the last two or three thousand years, are inconsiderable, when compared with those revolutions, which succeed NATURAL HISTORY. Id the creation. For as the surface of the earth was at iirst much softer than it is now, of consequence the same cause which at present produce but slight altera- tions for many centuries, were then capable of produc- ing very great revolutions in a few years. It is very evident, in my opinion, that the dry land, and even the summits of the highest mountains, were formerly cuvirc-d with the waters of the sea ; because shells and other marine animals are still found upon the very tops of mountains. It appears too that the waters of the sea have remained a great number of years upon the surface of the earth ; for such immense banks of shells have been discovered, as to render it impossible for so great a number of animals to have existed at the same time. This circumstance proves pretty clearly, that, though the materials on the surface of the earth wore then easily disunited by the water, yet these transpor- tations ceuld not be suddenly effected. Even though it should be supposed, that, at the deluge, all the shells were transported from the bottom of the ocean and de- posited upon the dry land ; yet, besides the difficulty .hlishing this hypothesis, it is evident, . that as shells are found incorporated in marble, and.in the rocks of the highest mountains, we must likewise suppose that all the^e marbles and rocks w,ere formed at the same time, and that too when the deluge took place ; and that before tills grand revolution, there were nei- ther mountains, nor marbles, nor rocks, nor clays, nor matter of any kind like that with which we are now acquainted. But without dwelling any longer upon this particular I shall confine myself to well authenticated facts. It is certain, that tli£ waters of the sea have, at one pt- riod or other, continued for a succession of ages upon 16 NATURAL HISTORY. what we now know to be dry land ; and that, of con- sequence, the vast continents of Asia, Europe, Africa, and America, were then the bottom of an immense ocean, replete with every thing which the present one produces. It is also certain that the different strata of the earth are horizontal and parallel to one another, which situation is occasioned by the operation of the waters. The horizontal position of water is almost universal ; in plains the strata are perfectly horizontal. And it is only in the mountains that they are inclined to a horizon ; because they have been originally form- ed by sediments deposited upon an inclined base. Now these strata must have been formed gradually ; for nothing is more frequent than strata composed of hea- vy materials placed above light ones, which could not have been the case, if the whole had been blended and dissolved by the deluge, and then precipitated. Another circumstance requires our attention. No- thing but the motion and sediments of water could possibly produce the regular position of the various strata of which the superficial part of this earth is composed. And as both the highest mountains, and the lowest vallies consist, of parallel strata, this par- allel and horizontal position of strata must be the ef- fect of an uniform and constant cause. And hence we conclude that the dry and habitual part of the earth has remained a long time under the waters of the sea, and must therefore have undergone the same changes which are at present going on at the bottom of the ocean. By examining therefore v.-hat passes in the bottom of this sea, we shall soon be able to draw some rational conclusions respecting the external figure and internal constitution of the earth, NATURAL HISTORY. 17 The ocean, since the creation of the solar system, has been subject to a regular flux and reflux. This motion, which uniformly takes place twice in twenty- four hours, is principally owing to the moon, and is greater in the equatorial regions than in ether climates. The earth too performs a rapid motion on its axis, and consequently has a centrifugal force, which is also the greatest at the equator ; which last circumstance proves that the earth must be more elevated under the equator than at the poles. From the tides, therefore, and the motion of the earth combined, we may fairly conclude, that, though this globe had originally been a perfect sphere, its diurnal motion, and the ebbing and flowing of the tides, must, in a succession of time, have elevated the equatorial part-;, bv gradually carrying mud, shells, &c. from other climates, and depositing them at the equator. On this hypothesis, the great- est inequalities on the earth's surface ought to be found and indeed are found near the equator. But farther, as the alternate motion of the tides has been regular since the existence of the world, may we not naturally imagine, that, at each tide, the water carries from one place to another a small quantity of matter, which falls to the bottom as a sediment, and forms those ho- rizontal and parallel strata that every where appear. It may, however, be objected, that as the flux is equal to, and regularly succeeded by the reflux, the two motions will balance one another, and, of conse- quence, that thi; cause of the formation of strata must be chimerical, as the bottom of the ocean can never be affected by a uniform alternate motion of the waters. But, in the first place, the alternate motion of the waters is far from being equal, as the sea has a con- tinual motion from east to west, and also as the agi' Vol. I. P, IS NATURAL HISTORY. tations occasioned by the winds produce great inequa- lities in the tides. By every motion of the sea too, particles of earth, and other materials, must be carried from one place and deposited in another ; and these collections of matter must assume the form of parallel and horizontal strata. Besides, on all coasts where the ebbing and flowing are discernible, numberless ma- terials are brought in by the flux, which are not carried back by the reflux. Thus ths sea gradually increases on some places, and recedes from others. But in order to remove every doubt, let us examine more closely the practicability of a mountain being formed at the bottom of the sea, by the motion and sediments of the water. On a coast which the sea lashes with vio- lence, some part of the earth must be carried off by every stroke of the waves. Even where the sea is bounded by rock, it is a well authenticated fact, that small particles are carried off from the rock by the re- treat of every wave. Those particles of earth or stone being transported to some distance, it happens that, when the agitation of the water is abated, the particles are precipitated in the form of a sediment, and lay the foundation of a first stratum, which will soon be succeeded by a similar one. In process of time this gradually accumulating mass will become a mountain in the bottom 'of the sea, perfectly like, both in external and internal structure, the mountains on the dry land. When the bottom of the sea too, at particular places, is troubled by the agitation of the water, earth, clay, shells, and other matter must be removed from thence, and deposited else- where. For divers assure us, that the bottom of the sea, at the greatest depths to which they descend, •is so strongly agitated by the water, that earth, clay, NATURAL HISTORY. 19 and shells, are removed to great distance?. Trans- portations of this kind must therefore go on in every part of the ocean ; and the matters transported, after having subsided, must raise eminences similar to the composition and structure of our mountains. We must not however imagine that these matters cannot* be carried to a great distance ; for we daily find grain, and other productions of the East and West Indies, landing on our coasts. These bodies may be said to be specifically lighter than the water, and the other substances specifically heavier. Yet as they arc re- duced to an impalpable powder, they may be long suspended in the water, and consequently transported to any distance. It has been imagined that the agitation, produced by the winds and tides, docs not affect the bottom, when it is very deep. But the truth is, tliat whate- ver be the depth, the power which occasions the flux and reflux operates equally upon every particle of the - mass at the same time. It therefore appears that the tides, the winds, and whatever else gives birth to mo- tion in the sea, must produce heights and inequalities in its boUoiir; and that these eminences must uni- formly be composed of regular strata, either horizon- tal or inclined. Whenever civinencc.s are formed they interrupt the uniform motion of the waters, and produce new ones called currents. Between two neighbouring heights in the bottom of the ocean, there must be a current which will follow their common direction, and, like a river, cut a channel, the angles of v.hu h will be alter- nately opposite through the whole of its course. These heights must continually increase, ss ti tor will depoit its ordinary ?edicr:ent upon their ri 20 NATURAL HISTORY, and thus, by means of the different motions and sedi- ments, the bottom of the ocean, though formerly- smooth, must soon he furrowed, and interspersed with hills and chains of vast mountains, as we find it at pre- sent. And the materials which consisted of sandy and crystalline particles, would produce those masses of rock and flint in which v, e find crystals and preci- ous stor.es. Others composed of stony particles and shells, produce lime stone and marble ; and, lastly, particles of shells mixed with a pure earth, have given risa to all our beds of rnarle and chalk. It may be said, however, that the greater number of hills, whose summits consist of solid rocks of moor stone, or marble, are founded upon small eminences composed of lighter materials. But the explication of this phenomenon is perfe :tly easy. The waters would first operate upon the upper stratum, either of coasts, or the bottom of the sea. This upper stratum general- ly consists of clay, or sand ; and these light substances being carried oiF and desposited sooner than the more dense and solid, they woutd of consequence become foundations for the more heavy particles to rest upon. The harder and more ponderous substances would next be subjected to the attrition of the water, and carried off and deposited about the hillocks of sand or clay. These small stony particles would, in process of time, form those solid rocks which we now find on the tops of hills and mountains. And as particles of stone are heavier than those of either sand or clay, it is probable that they were originally covered by superior strata of considerable depth ; but that they now occupy the highest stations, because they were last transported; b.y the. waves.. NATURAL KISTOilY. 212 To confirm this reasoning, it is worthy of remark, chat the different strata of stones in quarries are al- most all horizontal or regularly inclined. Indeed the strata of granite vitrifiable sand, clays, marbles, cal- careous stones, chalk, and marlcs, are always parallel or equally inclined ; and the disposition of strata, as deep as mankind have penetrated is the same. Those heds of sand and gravel which are washed down from the mountains, must, in some degree, be excepted from the general rule. And as they are formed by rivers and brooks which often change their channels, it is not surprising that they are so frequent. The strata formed by rivers are not very ancient ; they are easily distinguished by their frequent interruptions, and the inequality in thickness, which is constantly vary- ing, but the ancient strata uniformly preserve the same dimensions throughout. These modern strata may likewise be distinguished by the form of the stones and gravel they contain, which bear evident marks of having been rounded by the motion of water. The same ob- servation holds good with respect to those beds of turf, and corrupted vegetables, which are found in marshy grounds, immediately below the soil ; and which have derived their origin from successive accumulations of decayed trees, and other plants. The strata of slime and mud being formed by stagnating waters, or the inundations of rivers, are neither so perfectly horizon- tal, nor so uniformly inclined as those produced bv the regular motions of the sea. In strata formed by rivers, we meet, with river and seldom with sea shells ; but in the ancient strata there are no river shells ; the sea shells are numerous, well preserved, and all placed in the same manner. From whence could this beautiful regularity proceed? Instead of regular strain, why do 12 NATURAL HISTORY. we not find the materials which compose the earth hud- dled together without order ? Why are not rocks, mar-- bles, clays, marlcs, &c. scattered promiscuously, or joined by irregular or vertical strata ? Why are not heavy bodies found in a lower situation than light ones ? It is easy to perceive, that this uniformity of nature, this species of organization, this union of different ma- terials by parallel strata, without regard to their weights could only proceed from a cause equally powerful and uniform as the motions of the .sea, produced by regu- lar winds, or by the flux and reflux, &c As these causes act with superior force under the equator than in other climates, the chains of mountains are most extensive in its neighbourhood. Thus the mountains of Africa and Peru are both the highest and most extensive in the world. The mountains of Europe and Asia, which extend from Spain to China, are not so high as those of Africa and South America. Be- sides, in the northern seas, the islands are but few, when compared with those in the Torrid Zone. As islands, therefore, are nothing but the summits of moun- tains, it is clear there are more inequalities on the sur- face of the earth near the equutor than in northerly climates. Those vast chains of mountains which run from west to east in the old continent, and from north to south in the new, must have been formed by the general mo- tion of the tides. But the origin of smaller mountains and hills may be ascribed to particular motions occasion- ed by winds, currents, and other irregular agitations of the sea, or to a combination of all those motions which are capable of infinite variations. But how has it happened that this earth, which, . from time immemorial, hus been an kmncnse continent.. NATURAL HISTORY. 23 /tumid, if formerly the bottom of an ocean, be now so i::urh elevated above the waters, and so completely se- parated from them ? A little reflection will furnish us with at least plaus- ible solutions. We daily observe the sea gaining ground on certain coasts, and losing it on others. The ocean has a general and uniform motion from east to west ; there are whole provinces which human industry can hardly defend from the fury of the wares, and there are islands which have but lately emerged from the waters, and regular inundations. History too informs us of inundations and deluges of a more extensive na- ture. Should not all this convince us, that the surface of the earth has undergone very great revolutions, and that the sea may have given up the greater part of the ground which she formerly possessed? Lot us suppose for example, that the old r.nd new worlds were for- merly but one continent, and that, by a violent earth- quake, the ancient Atalantis of Plato was sunk. What would be the consequence? The sea would rush in from all quarters, and from what is now called the Atlantic Ocean, and vast continents would of conse- quence be left dry. This great, revolution might be effected by the sudden failure of some immense cavern in the interior part of the globe, and an universal de- luge would infallibly succeed. I am inclined however to think, that to effect such a revolution would require •a very long period. Be these conjectures as they may, it is certain that the revolution has happened, and I believe that it has happened naturally. It is a well-authenticated fact, that the ocean has a constant motion from east to west; which motion, like the trade-winds, is not only perceived between the tropics hut through the whole temperate climates, and as near -24 NATURAL HISTORY. ? the poles as navigators have approached. In conse- 1 quence of this motion, the Pacific Ocean must make continual efforts against the coasts of Tartary, China, and India; the Indian Ocean must act against the east coast of Africa, and the Atlantic must operate in a similar manner upon the eastern coasts of America. Hence the sea has gained, and will always gain on the east, and lose on the west. If such is the natural effect of the motion of the sea from east to west, may we not suppose that Asia, and all the eastern conti- nent, is the most ancient country in the world? and that Europe and part of Africa, particularly the west parts of these continents, as Britain, France, Spain, &c. are more recent countries ? Both history and physics concur to establish this hypothesis. But there are many lands lower than the level of the sea, and defended only by banks, which the action of the waters must gradually destroy, and of conse- quence the lands must then become part of the ocean. The mountains too are daily diminishing ; and every little brook carries earth, and other materials, from the high grounds into the rivers, by which they are at last transported to the ocean. Thus the bottom of the sea is gradually filling up, and the surface of the earth is approaching to a level. But we shall give a detail of facts, in order to ex- plain the different alterations which the earth has un- dergone, whether by irruptions of the sea upon the land, or by the sea returning from lands it formerly occupied. That irruption which gave birth to the Mediterra- nean is no doubt the greatest. The motion through the straits of Gibraltar is contrary to the motion in every other strait; for the general motion of the sea NATURAL HISTORY. 25 w from east to west ; but in the straits of Gibraltar it Is from west to east. This circumstance is a clear proof that the Mediterranean Sea is not an ancient gulf, but •that it has been formed by an irruption, produced by some accidental cause. When the ocean forced this passage, it ran through the straits with much more rapidity than it does now, and immediately deluged that large tract of land which formerly joined Europe with Africa. The waters covered all the grounds which were lower than the level of the ocean ; and no part of them is to be seen at present, except the tops of some of the mountains, Mich as part of Italy, Sicily, Malta, Corsica, Sardinia, Cyprus, Rhodes, and the islands of the Archipelago. It is not improbable, that the Black Sta will, some time or other, be entirely divided from the Mediter- ranean ; and that the Bosphorus will be choaked up, whenever the rivers shall have accumulated a quantity of materials sufficient for that purpose. The Caspian and Black Seas should rather be con- sidered as lakes than as gulfs of the ocean ; because they are perfectly similar to other lakes that receive a number of rivers without any visible outlet, as the Dead Sea, several lakes in Africa, and elsewhere. But that we may give some recent examples of the changes of sea into land and of land inio sea. At Venice the bottom of the sea is constantly rising ; and the same thing may be said of most harbours, bays, and mouths of rivers. In Holland, the bottom of the sea is elevated in many places ; the gulf of Zudovzee and the straits of the Texel, cannot receive such large vessels as formerly ; and it is quite evident that the sea is always dammed up, wherever great rivers empty themselves. The Rhine is lost in tie sdnds which Vok I. C %S NATURAL HISTORY. itself has accumulated. The Danube, the Nile, and e!l large rivers, after they have- transported great quantities of slime, sand, &c. never arrive at the sea by a single channel. Marshes are drained everyday; lands, forsaken by the sea, are now ploughed and sown ; we navigate whole countries now covered by the wa- ters. In short, we see so many instances of land changed into water, and water into land, as to con- vince us that, in time, the gulfs of the ocean will be- come continents, the isthmuses will be changed into straits, and the tops of the mountains concerted into shoal y rocks in the sea. Still, however, those perpendicular fissures, which are equally diffused through rocks, clays, and every constituent matt rial of the globe, remain to be consider- ed. The perpendicular fissures are indeed placed at greater distances from one another than the horizontal ; and the softer the matter, the more tli.si;ir,t arc the fis- sures. In marble and hard stone, the fissures are only a few feet asunder. If the mass of rock be extensive, the distance between the fissures is some fathoms. The cause of perpendicular fissures is easy investi- gated. As various materials constituting the different strata were transported by the waters, and deposited in the form of sediments, they would at first be in a yery diluted state, and would by degrees harden and part with the superfluous quantity of water they con- tained. In the process of drying, they would contract and split at irregular distances. The contraction, therefore, of the parts in drying is the cause of per- pendicular fissures; for I have often remarked, that the sides of tho.se fissures, through their whole e*xtentr correspond as exactly as the two sides of a split piece* of wood. NATURAL HISTORY. 27 Perpendicular fissures vary greatly as to the extent •of their openings. It is clear, ho>wever, that the fis- sures, whose openings are small, have been occasioned solely by drying. But those which extend several feet are partly owing to the sinking of the foundation upon one siue while that of the other remains firm. When rocks are founded on clay or sand, they sometimes slip a little to a side ; and the fissures are of consequence increased by this motion. I have not taken notice of those prodigious cuts which are found in rocks and mountains, arid which could be produced by nothing but ths sinking of immense subterraneous caverns that were unable to support the load any longer. But these cuts in mountains are not of the same nature with per- pendicular fissures : They appear to have been ports opened by the hand of mature for the communication of nations. This appears to be the intention of all openings in chains of mountains, and of those t?l raits by which different parts of the ocean arc con- nected ; as the straits of ThermOpyle, of Gibraltar, &c. :>s or ports in Mount Caucasus, i he Cordeliers, £c. These great sinkings, though owing to accidental and secondary cantos, are leading facts in ihe history of the earth, and have contributed much to change the appearance of its surface. Most of them have been produced by subterraneous fires, whose explosions ;;ive birth to earthquakes and volcarioes. But though the f;>rce of inflamed matter pent up in the bowels of the earth be great, and though its- effects appear to hi1 protfigious, wevcar,not suppose that these subterra- neous fires are only branches of an immense abyss of 'flame in the centr: of the t-a-th ; nor do we believe that those fires have their seat at a great depth helovr dite surface, asmsLter carsnct begin to burn,, cr at least 99 NATURAL HISTORY. , the inflammation cannot be supported without air. In order to be convinced that the matter emitted by volca~ njes does riot come from any considerable depth, we have only to attend to the height of the mountain, ancV ta consider th« amazing force which would be necessary to project, stones and minerals to the height of half a league ; for JEtna, Hecla, and other volcanoes, have at least that elevation. This, however, is not inconsistent with volcanoes being the cause of considerable earthquakes ; nor does it contradict, the communication of one volcano with another, by means of subterraneous passages, For to produce an earthquake in a plain, it is not necessary that the bottom of the volcano should be below the le- vel of that plain, nor that there should be subterraneous- cavities filled with the same burning matter under it. A violent explosion may by its reaction produce an earthquake of considerable extent. I would not, how- ever, be thought to say that no earthquakes derive their existence from subterraneous fires ; all I mean is, that there are earthquakes produced solely by the ex- plosion of volcanoes. It is not dii'iicult to account for volcanoes appearing only in mountains ; for greater quantities of minerals, sulphur, and pyrites, exist in mountains, and nearer the surface than in the plains. Besides, mountains are more subject to the impressions of the air, and receive more rain and moisture, by which mineral substances are capable of being fermented to such a degree as to produce actual inflammation. And mountains having diminished, nearly in proportion to the quantity of mat- ter thrown out, is another proof that the volcanoes are not so deep as the base of the mountains, and even that they are not much below the summit. NATURAL HISTORY. 2^ In several places, earthquakes have formed consider- able hollows, and even some large gaps in mountains All other inequalities are coeval with the mountains themselves, and owe their existence to currents in the ocean. From what has been said, it is easy to perceive hcnr much subterraneous fires have contributed to change both the surface and internal part of the globe. But it is difficult to conceive how any sensible alteration upon the land can be produced by the winds. Their do- minion would appear to be confined to the sea ; yet it is well known that the winds raise mountains of sand in Arabia and Africa;, and that they frequently carry these sands many leagues into the sea, where they form banks, downs, and even islands. Every body knows that hurricanes are the scourge of the Antilles, of Madagascar, and of other countries, and that their impetuosity is so violent as to drive back rivers, to overthrow rocks and mountains, to scoup out holes and gulphs in the earth, and totally to change the face of those unhappy countries which they infest. But the greatest changes upon the surface of the earth are produced by rains, rivers, and torrents from the mountains. These derive their origin from va- pours raised by the sun from ihe surface of the ocean, and which are transported bv the winas through eve- ry climate. The progress of these vaponrs is inter- rupted by the tops of 'the mountains, where they ac- cumulate into ciouds and descend in the form of rain, dew, or snow. By their intrinsic gravity, they run to the bottom of the mountain's, and penetrating or dissolving the lower grounds, they sweep along with them sand and gravel, furrow the plains, and thus open passages to the sen, which always gains as much? 30 NATURAL HISTORY water by rivers, as it loses by evaporation. Tht windings in the channels of rivers uniformly have corresponding angles on their opposite banks ; and as, mountains and hills, which may be considered as the banks of the vallies by which they are separated, have also, sinuosities with corresponding angles, this circumstance seems to demonstrate, that the vallies have gradually been formed by currents of the ocean, in the same manner as the channels of rivers have been produced. The waters which run upon the surface, compose perhaps not one half of the quantity that is produced by vapour. In almost all the vallies and low grounds at a certain depth, water is uniformly to be found ; hut in high grounds, it is impossible to extract water from the bowels of the earth. There are extensive countries where no wells can be obtained. In the east, and especially in Arabia, Egypt and Persia, wells and springs are seldom to be met with. To supply their place the inhabitants have been obliged to make large reservoirs to collect the rain water. In plain countries, furnished with large rivers, it is al- most impossible to break the surface of the earth without "finding water. The greatest part of the water so liberally diffused through low grounds, comes from the neighbouring hills and eminences. During great rains, or the sudden inciting of snow, part, of the water runs upon the sur- face, but most of it penetrates the earth arid rocks by small chinks and fissures. It emerges indeed as soon ?s it can find an opening ; but it often creeps along un- til it can find a bottom of clay, or hard earth and there •forms subterraneous lakes, brooks, and perh;:ps rivers, whose channels arc ccn.-i"ned to eternal oblivion. NATURAL HISTORY. SI There are several lakes which neither receive nor give origin to any liver. A greater number, however, receive no considerable river, but are the sources of the largest in the world. Such are the lakes from which the river St Laurence arises ; the lake Chiame, from which two large rivers proceed, that water the kingdoms of Asem, and Pegu ; the lakes of Assiniboii in America; those of Ozera in Muscovy; those too which give rise to the Bog and the Irtis, and many more. It has been affirmed, indeed, that lakes are to be found on the tops of the highest mountains ; but those found en the Alps, and other elevated situa- tions, all derive their origin from the waters which run down the sides, or are filtered through the bowels of these superior eminences. Hence the existence of subterraneous collections of water ; for mountains, hiiis, and heights of every sort, are exposed on every side to the weather. The waters which fall upon any place of an elevated situ- ation, must, after penetrating the earth, from the de- clivity of the ground, break forth at many places, springs, and fountains ; and of consequence little wa- ter will be found in the bowels of mountains. But, in plains, as the water filtrated through the earth can find no vent, it must be collected in subterraneous caverns, or dispersed in small veins 'among sand and gravel. The bottom of a pit or well is only a small artificial bason, into which the water insinuates itself from the higher grounds. Hence it is, that, though water may be found in any part of a plain, only a number of wells can be supplied in proportion to the quantity of water diffused, or rather to the extent of the higher grounds from which it comes. To find water, it is unnecessary to dig below the level of the river. Even what is found in the earth. 32 NATURAL HISTORY. below the level of rivers, is not derived from them. Five or six feet of earth is sufficient to contain water, and to prevent its escape. It would not be easy to make an. exact calculation of the quantity of subterraneous wafers that have no apparent issue. Many suppose that it is far greater than all that is upon the surface of the earth. But it is probable that the quantity of subterraneous wa- ters which never appear at the surface, is very incon- siderable ; For, if the number of subterrjmeous rivers were so great, why do we never see any of their mouths break out like springs, on the surface. But rivers likewise produce considerable changes on the surface of the earth ; they carry off the soil ; they wear away the most solid rocks, and sweep off what- ever opposes them. The same effects would result from subterraneous rivers. But no such changes have ever been discovered ; the different strata every where pre- serve their parallel and primitive position. From what we have advanced, we may conclude, that the flux and reflux of the ocean have produced all the mountains, valleys, and other inequalities on the surface of the earth ; that currents of the sea have scooped out the valleys elevated the hills, and iestowed on them their corresponding directions ; that the waters of the ocean too, by transporting and de- positing earth, £c. have given existence to the par- allel strata ; that the waters from the heavens destroy the effects of the sea, by diminishing the height of the mountains, filling up the vallies, and chosking the mouths of the rivers ; and, by reducing every thing to its former level, they will restore the earth to the sea, , by its natunil operations, will again create nevr NATURAL HISTORY. 3$ continents, beautifully diversified with mountains and rallies, and in every respect like those which we now inhabit. The surface of this globe is divided, from one pole to the other, into two immense bands of earth, and two of water. The principal of these bands is that which is called the ancient continent, and which includes Eu- rope, Asia, and Africa. This continent, if measured from the two extreme points, that is, from the eastern point of Tartary to the Cape of Good Hope, will pro- duce a line of 3600 leagues ; and if measured direct- ly from north to south, we shall find that there are only 2500 leagues from the northern Cape of Lapland to the southernmost point of the Cape of Good Hope. The utmost breadth of this continent, that is from the western coast of Africa to Trefana, as far as Nisingpo, on the east coast of China, is about 2800 leagues. Another line may be drawn also from Brest in Brit- tany, as far as the coast of Chinese Tartary, will be about 2300 leagues. The old continent, on the best calculations, may be said to contain 4 94-0,780 square leagues, which is about a fifth part of the surface of the globe, and may he considered as a large belt of earth, with an inclination to the equator of about 30 degrees. The new continent is called America, and is divided into north and south. Its greatest length may be es- timated from the mouth of the river Piata in Paraguay to the lake of the AssiniboHs which amounts to about 2500 leagues. It is supposed to contain 2.140,212 square leagues. The whole superficial contents there- fore, of both the old and new continents, are about 7,080.093 square leagues, rot near a third of the sur- Vol I. D '** NATU&AL HISTORY. face of the globe, which contains 25,000,000 square leagues. Of these lines, which divide both the continents in- to two equal parts, it is worthy of remark, that they both terminate at the same degrees of north and south latitude ; and that the two continents make mutual advances perfectly opposite to one another, to wit, those on the African coast, from the Canary Isles to Guinea ; and those of America, from Guiana to the mouth of the Rio-Janeiro. It therefore appears, that the most ancient lands on the globe, are those which extend from 200 to 250 leagues on each side of the two lines that we have al- ready taken notice of. Agreeable to which idea, we con- clude that in the old continent, the most ancient coun- tries of Africa are those which reach from the Cape of Good Hope to the 'Red Sea and Egypt, and are about 500 leagues broad ; and, of consequence, that the whole western coast of Africa, from. Guinea to the Straits of Gibraltar, are new lands. In the new continent we shall likewise find, that Terra Magellanica, the eastern part of Brasil, of the country of the Amazons, of Guiana, and of Canada, are new lands, when compared with Tucuman, Peru. Terra Firma, the islands in the Gulf of Mexico, Florida, the Missisippi, and Mexico. It was but a small part of the globe with which the ancients were acquainted. All America, the Arctic circle, Terra Australis the Magellanic, and a great part of the internal regions of Africa, wore entirely un- known to them. They knew not that the torrid zone was inhabited, although they had navigated around Africa; for it is 2200 years since Neco king of Egypj NATURAL HISTORY. •gave vessels to the Phoenicians, which departed from the Red Sea, coasted around Africa, doubled the Cape of Good Hope, and having employed two years in this voyage, the third year they filtered the straits of Gib- raltar*. Nevertheless, the ancients were not acquaint- ed with the property which the load-stone had of turn- ing towards the poles, although they knew that it at- tracted iron. They were ignorant of the general cause of the flux and refhix of the sea ; they were not cer- iain the ocean surrounded the globe without interrup- tion ; some indeed suspected it, hut with so little foun- dation, that no one dared to say, or even conjecture it was possible to make a voyage round the world. Ma- gellan was the first who made it A. D. 1519 in 112-i days. Sir Francis Drake was the second, in 1577, and he did it in 1056 days; afterwards Thomas Ca- vendish made this great voyage in 777 days, in the year 1 586. These famous voyagers were the first who demonstrated physically, the globular form and extent of the earth's circumference : for the ancients were far from having a just measure of this circumference, al- though they had travelled a great deal. The general and regulated winds, and the use to be made of them in long voyages, were also absolutely unknown to them ; therefore, we must not be surprised al the little progress they made in Geography, since at present, in spite of all the knowledge we have acquired by the aid of mathematical sciences, and the discovery of naviga- tors, many things remain still to be found, and vast countries to be discovered. As there is so large a portion of the globe with which we are unacquainted, particularly near the poles, where the ice has never permitted any navigator to penetrate, * Sc« Hwcd. Lih. if. 36 NATURAL HISTORY. we cannot exactly know the proportion between the surface of the earth and that of the sea ; only as much as may be judged by inspection of what is known, there is more sea than land. If we would have an idea of the enormous quantity of water which the sea contains, let us suppose one common and general depth to the ocean; by comput- ing it only at 200 fathoms, or the 10th part of a mile, we shall see that there is water sufficient to cover the whole globe to the height of 600 feet of water, and if we would reduce this water into one mass, we shall find that it forms a globe of more than 60 miles diameter. The form of the earth is not that of a perfect globe, but rather what is termed a spheroid, a globe which is flattish at the poles, the axis, therefore, or line, which may be supposed to pass through it at the equator, is to its axis at the poles in the proportion of 230 to 229- The solid parts of the earth are formed of beds or strata of different materials, which lie one upon another in a regular order. The first stratum consists of common soil, mixed with a variety of decayed vegetable and animal substances, and with stony and sandy particles. In different parts of theworld the other strata are found to consist of different materials, and differently dispos- ed. In some parts the strata are horizontal, in others they are inclined ; and veins or fissures of metals, coals, and other minerals, frequently penetrate through the dif- ferent beds or strata to a great depth, and divide them. At Marly-la- Ville in France, which is a high country, but flat and fertile, the following strata were found ar- ranged horizontally. From the shells which were found in N" 16. we may conjecture, that at some period the soil of Marly-la- Ville was the bottom of the sea, but has since been raised to the height of 75 feet.

Every stratum, whether horizontal or inclined, ha* an equal thickness through its whole extent : that is to say, every bed, of any matter whatsoever, taken se- parately, has an equal thickness through its whole ex- tent ; for example, when the bed of stone in a quarry is three feet thick in one part, it will have the same thickness throughout : if in one part it is found to be six feet thick, it will be so throughout. In the quar- ries about Paris, the bed of good stone is not thick, and scarcely 18 or 20 feet thick ; in other quarries, as those of Burgundy, the stone is much thicker ; it is the same with marble ; the black and white marble have a thicker bed ; the coloured are commonly thinner ; and I know beds of very hard stone, which the farmers in Burgundy make use of to cover their houses, that are not above an inch thick. The thickness of different beds, therefore, are different, but each bed preserves the same thickness throughout its extent ; in general it may be said, that the thickness of the horizontal strata is so greatly varied, that it is found from one line and less to 1, 10, 20, 30, or 100 feet thick; the an- cient and modern quarries which are horizontally dug ; the perpendicular, and other divisions of mountains, prove that there are extensive strata in every direction. The various strata of which the earth is composed, are not disposed according to the order of their specific weight ; for we often find strata of heavy matters plac- ed on strata of lighter. To be assured of this, we have only to examine the nature of the earth on which rocks are placed, and we shall find that it is generally cla}', which is specifically lighter than the matter of the rock. In hills and other small elevations, we easily discover the base on which rocks are placed ; but it is not s(* with large mountains, not only the summit is rock. 40 NATURAL HISTORY. but those rocks are placed on other rocks ; tlicre air mountains upon mountains, and rocks upon rocks, to such a considerable height, and in so great an extent of ground, that we can scarcely be certain where there is earth at bottom, and of what nature it is. We set- peaked rocks which are many hundred feet high ; these rocks rest on others, which perhaps are no less so ; nevertheless, may we not compare great with small ? and since the rocks of little mountains, whose bases are to be seen, rest on the earth less heavy and solid than stone, may we not suppose that the base of hiyh mountains is also of earth ? In a soil where flint is the predominant stone, the country is generally fertile, and if the place is unculti- vated,, and these stones have been long exposed to the air, without being moved, the upper superfices is al- ways very white, while the opposite side, whi:h touches the earth} preserves its natural colour. If the black- est, and most flinty flint be exposed to the weather, in less than a year its surface will change colour ; and if we have patience to pursue this experiment, we shall see it by degrees lose its hardness, transparency, and other specific characters, and approach every day near- er and nearer the nature of argile. What happens to flint happens to sand ; each grain of sand may be considered as a small flint, and each flint as a mass of grains of sand, extremely fine and exactly grained. The example of the first degree of decomposition of sand is found in the brilliant and opake powder sailed Mica, in which potters earth and slate are always diffused. The entirely transparent flints, the Quariz, produce, by decomposition, fat and soft talc, as pctrih'able and ductile as clay : and it ap- pears to me that talc is a mediate term between glass or NATURAL HISTORY. 4t transparent flint and nrpile; whilst, on tlte contrary* coarse and impure fiint, by decomposing, passes to potters earth without any intermedium. Our factious £>!ass proves also the same alterations: it decomposes in the air, and perishes in some degree by remaining in the earth. At first its superficial scales exfoliate ; by working it we perceive brilliant scales fly from it ; but when its decomposition is more ad- vanced, it crumbles between the fingers, and is re- duced into a very fine white talcy powder ; and art has even imitated nature in the decomposition of glass and flint. CHAP. II. •OF HILLS SEAS RIVERS AND LAKES THEIR NA- TURE AND PROPERTIES. IF, in place of that beautiful variety of hills and val- lies, of verdant forests, and refreshing streams, which at present delight our senses, the earth were an even and regular plain ; a dreary ocean would then cover the whole globe, and it would be merely the habita- tion of the scaly race. It cannot therefore be supposed, that even at first the surface of the earth was perfectly regular ; and since its first production, a variety of causes, the mo- tion of the waters, the subterraneous fires, the wind, and other external causes, have contributed much to this irregularity. Next to the elevation of mountains, the depths of the ocean form the greatest irregularities ; this depth Ss very different even at great distances from land ; Vol. I. E 48 NATURAL HISTORY. it is said there are parts above a mile deep, but these are few, and the most general profundities are from 60 to 150 fathoms. The gulphs bordering on the coasts are much shallower, and the straits have generally the least depths. In general, the depths in open seas increase or di- minish pretty regularly, being for the most part deeper the farther from land. But there are places in the middle of the sea, as at the Abrolkos in the Atlantic, where large shelves appear ; and in other places, there are vast sand banks, to which the East Indiamen are no strangers. Along coasts, the depths are also very irregular. Yet it may be laid down as a certain rule, that the depth is always proportioned to the height of the coast : the same remark is equally applicable to rivers. The highest mountains in Asia, are Mount Taurus, Mount Imaus, Caucasus, and the mountains of Japan, all of which are higher than any in Europe : the high- est mountains in Africa, i, e. the great Atlas, and the mountains of the moon, are at least as high as those in Asia, and the highest of all are in South America, particularly those of Peru, which are more than 3000 fathoms higher than the level of the sea. In general, the mountains between the tropics are loftier than those of the temperate zones, and these more than those of frigid zones, so that the nearer we approach the equator, the greater are the inequalities of the earth : these in- equalities, although very inconsiderable with respect to us, are nothing when considered with respect to the terrestrial globe. Three thousand fathoms difference to 3000 leagues diameter, is one fathom to a league, or one foot to 2300 feet, which on a g'obe of 2 feet and a half diameter, does not make the 6th part of a line. NATURAL HISTORY. 43 Hence this earth, which appears to us to he crossed and cut hy the enormous height of the mountains, and by the frightful depth of the sea, is, when we consider its size, so very slightly furrowed with irregularities, that they can make no variation upon its general figure. Upon the continents the mountains are continued, and form chains. In islands they appear to be more interrupted and isolated, and generally raised above the sea, in form of a cone or pyramid, and are called peaks. The peak of Teneriffe is one of the highest mountains on the earth ; it is near a mile and a half high perpen- dicular from the level of the sea ; the peak of St George in one of the Azores, and the peak of Adam in the island of Ceylon, are also exceedingly high. All these peaks are composed of rocks, piled one above ansther, which emit each from their summits, fire, cinders, bitumen, minerals, and stones. There are even islands which are precisely only as tops of mountains, as the island of St Helena, Ascension, most of the Azores, and Canaries : and we must remark, that in most of the islands, promontories, and other projecting lands in the sea, the middle is always the highest, and they are generally separated by chains of mountains, which divide them in their greatest length ; as the Grampian mountains in Scotland, which extend from east to west, and divide Great Britain into two parts ; it is the same with the islands Sumatra, Lucon, Borneo, Celebes, Cuba, and St Domingo, and also Italy, which is tra- versed through its whole length by the Appenines. With respect to the depths on the surface of the earth, those of the ocean are, no doubt, the greatest, but as these can only be discovered by sounding, we shall take notice of none but such as appear on the dry land. The precipices then which are between rocks, are form- 44 NATURAL HISTORY. ed by the sinking of rocks, the base of which sometimes gives way more on one side than the other, by the action of air and frost, which splits and divides them ; and by the impetuous fall of torrents, which opens passages, and carries along with them whatever op- poses their violence. But these abysses, that is, these vast and enormous precipices found at the summit of mountains, and to the bottom of which it is not pos- sible sometimes to descend, although they arc above a mile or half a mile round, have been formed by the operation of fire. They were formerly the funnels of volcanoes, and all the matter which is there deficient has been ejected by the action and explosion of these fires, which are since extinguished for want of com- bustible matter. The abyss of mount Ararat, of which M. Tournefort gives a description in his voyage to the Levant, is surrounded with black and burnt rocks, as the abysses of /Etna, Vesuvius, and other volcanoes will be when they have consumed all the combustible ^natters they include. Plot, in his natural history of Staffordshire, mentions a kind of gulph, which has been sounded to the depth of 2600 perpendicular feet, without finding either water or bottom. Great cavities and deep mines are generally m mountains, they never descend to a level with the plains ; so we learn from them the internal structure of the mountain only, and not that of the globe. It was long thought that the cliains of the highest' mountains run from west to east, till the contrary di- rection was discovered in the new work! ; but no per- son before Mr Bourguet discovered the surprising re- gularity of the structure of t!,o-e ijjreat masses. After having crossed the Alps thiiiy tunes in fourteen dif- NATURAL HISTORY. 45 ferent parts, twice over the Appenine mountains, and made clivers tours in the environs of these mountains, and in mount Jura, he found that the contours of all mountains hear a striking resemblance to the works of regular fortifications. When the body of the moun- tain runs from east to west, it forms prominences, which face as much as possible to north and south ; tins admirable irregularity is so striking in Tallies, that we seem to walk in a very regular covered way : if, for example, we travel in a valley from north to south, we perceive that the mountain which is on the right forms projections or angles which front the east, and those of the mountain on the left, front the west ; so that, in fact, the prominent and concave angles, on each side, correspond with one another alternately. The angles which mountains form in great vallies are less acute, because the direction is less steep, and as they are farther distant from each other ; and in plains they are not so perceptible as in the course of rivers, which generally take up their elbows ; the middle of them naturally answer to the most striking projections, or the most advanced angles of mountains ; and this is the cause of the serpentine course of rivers. It is astonishing so obvious a fact should have remained so long unobserved, for when in a valley the inclina- tion of one of the mountains which border it, is less steep than that of the other, the river takes its course much nearer the steepest mountain, and does not flow through the middle of the valley. These observations might be confirmed by a num- ber of facts. The mountains of Switzerland, for in- stance, are steeper on the south ^iJo than on the north, and on the we.st than on the east side. But the most striking example is afforded by the mountains of 46 NATURAL HISTORY. Chili and Peru. The Cordeliers are exceedingly steep on the west side, but they have a gradual declivity towards the east, and they terminate in vast plains, which are terminated by the largest rivers in the world. This is a consequence of the parallel directions of the different chains of mountains ; and besides the whole continent of Europe and of Asia is broader from east to west, than from north to south ; for there are two modes of conceiving this direction. In the long and narrow continent of South America, there is only one principal chain of mountains, that is, from east to west, or from west to east; in fact, it is in this direction all the rivers of America flow, because, excepting the Cordeliers, there are no very extensive chains of moun- tains, and none whose directions are parallel to them. In the old as well as the new continent, most of tire waters have their greatest extent from west to east, and most of the rivers flow in this direction, which is owing to another cause, to wit, that there are many long chains of mountains parallel to each other, whose direction is from west to east, and because the rivers and other streams are obliged to follow the intervals which divide these chains of mountains, consequently one single chain of mountains, directed from north to south, will produce rivers, whose direction will be the same as that of those which issued from many chains of mountains, whose common direction is from east to west ; and it is for this particular reason, that the ri- vers of America have this direction common with those of Europe, Africa, and Asia. A remarkable phenomenon has been observed with respect to rivers, which is, that in the inland parts at a distance from the sea, they flow in a direct line, but in proportion as they approach their mouths they as- NATURAL HISTORY. 47 sume more of a winding course. In large rivers there is a considerable eddv along the banks ; and the near- er the sea this eddy is the greater. The surface of the water in rivers is by no means level from bank to bank ; on the contraiy, the middle of the stream is higher or lower than the water of the sides according to circumstances. When a river swells suddenly by the melting of snow or any other cause, the middle of the stream is sensibly higher than the sides : in one instance the elevation is said to have been three feet. On the other hand, when rivers approach their mouths the water near the sides is commonly more elevated than in the middle. The inundation of the Nile, though nothing can be more natural, has long afforded matter for curious and doubtful speculation. It is the rain which falls in Abyssinia and Ethiopia which occasions the swel- ling and inundation of this river, though the north wind must be regarded as the primitive cause. 1st, Be- cause it drives the clouds which convey this rain from the coast of Abyssinia: 2dly, Because blowing a- gainst the two mouths of the Nile, it forces the wa- ters back against the stream, and thus prevents them from pouring into the sea in too great a quantity : this circumstance may every year be relied on, when the wind being at the north, and suddenly veering to the south, the Nile in one day loses what it gathered in four. Inundations are generally greatest in the superior parts of rivers ; because the velocity of a river uni- formly increases until it empties itself in the ocean. But as the theory of running waters is subject toinany difficulties, we ought carefully to study the peculiari- ties of particular rivers. 48 NATURAL HISTORY. The greatest rivers of Europe arc, the Wolga, whose course from Reschow to Astracan on the Caspian Sea, is about ()50 leagues ; the Danube, which runs about 450 leagues, from the mountains of Switzerland to the Black Sea ; the Don, from the source of the Sosna, which receives it, to the Black Sea, runs 400 leagues ; the Nieper, which also falls into the Black Sea, after running 350 leagues ; the Duine, which empties itself in the White Sea, runs a course of about 300 leagues. The greatest rivers of Asia are, the Hoanho, which rises at Raja Rilron, and which, after running 850 leagues, falls into the middle of the gulf of Changi, in the Chinese Sea ^ the Jenisca, which runs from Lake Leling to the northern sea of Tartary, a course of about 800 leagues ; the Oby, from Lake Kila to the North Sea beyond Waigat's Straits, runs about ()00 leagues ; the Amour, in East Tartary, has a course of 575 leagues, from the head of the river Kerlon, which falls into it, to the sea of Kamtschatka. The river Menan may be measured from the source of the Longmu, which falls into it, to its mouth at Poulo-condor ; the Kian, which runs about 550 leagues, from the source of the Kinxa, which it re- ceives till it discharges itself in the sea of China ; the Ganges, which has a course nearly of the same extent with the Kian; the Euphrates, computing from the source of the Irma, which it receives; runs about 500 leagues ; the Indus, which runs about 400 leagues, and falls into the Arabian Sea. on the east of Guzarat ; and the Sirderoias, which runs about 400 leagues, and falls into Lake Aral. The greatest rivers cf Africa are, the Senegal, the course of which, comprehending the Niger, which i» NATURAL HlSTOllY. 4§ but a continuation of it, and the source of the Gatn- barou, which falls into the Niger, is about 1125 leagues; the Nile, which rises in upper Ethiopia, runs about 970 leagues. There are others, the courses of which are but little known, as the Zaira, the Coanza, the Couama, and the Quilmanci, but each of which \ve are acquainted with to the extent of 400 leagues. In America, the river of the Amazons runs above 1200 leagues. The course of the river St Lawrence in Canada is more than 900 leagues. The river Mis* sisippi runs above 700 leagues. The Plata extends more than 800 leagues, from its mouth to the source of the Parana, which it receives. The Oronoko runs above 575 leagues, if we reckon from the source of the river Caketa, near Pas to, a part of which falls into the Oronoko, and a part runs towards the river of the Amazons. The Madera which falls into the Amazons extends above 660 leagues. In order to ascertain the quantity of water discharged into the sea by all the rivers, we shall suppose the one half of the surface of the earth to be sea, and the other half to be dry land. We shall also suppose that the mean depth of the sea is 230 fathoms. The total surface of the earth is 170.981,012 square miles, and that of the sea is 85,4-90,506 square miles, which, when multiplied by one fourth, the depth of the sea, gives 213372,62() cubic miles for the quantity of water contained in the whole ocean. Now that we may pretty nearly ascertain the quantity ef water discharged into the sea from the rivers, let us take the river- Po, for example, which runs through Lombardy, and wa- ters a country 380 miles long. According to Riccioli, the breadth of the Po is 100 feet, and its depth is 10 feet, and it runs at the rate of 4 miles an hour. Con-* Vol. I. F 50 NATURAL HISTORY. sequenily, the Po discharges into the sea 200,000 cu- bical perches of water in an hour ; and as a cuhic mile contains 125,000,000 cuhic perches, the Po will re- quire 26 days to discharge into the sea a cuhic mile of water. It now only remains to determine the pro- portion that the Po bears to all the other rivers of the earth taken together, which cannot be done exactly. But, to come as near to the truth as possible, let us suppose the quantity of water, which the sea receives from the great rivers in every country, to he propor- tioned to the extent of the surfaces of those countries; and, consequently, that the country watered by the *°* and by the rivers that fall into it, is to the total surface of the dry land, as the Po is to all the rivers °f the earth. Now, from the most accurate charts, it appears, that the Po waters a country 380 miles long and 120 broad, which makes 45,6'00 square miles. But the surface of the dry land is 85,4-90,506 square miles ; consequently, the quantity of water conveyed to the sea by all the rivers, will be 1874 times greater than the quantity discharged by the Po. But, as 26 rivers, equal to the Po, furnish a cubic mile of water every day, it follows, that, in the space of a year, 1874 rivers equal to the Po, will convey to the sea 26,308 cubic miles of water ; and that in 8 1 2 years, all these rivers would discharge 21,372,626 cubic miles, which is a quantity equal to what is contained in the ocean ; of course, if the ocean were empty, 812 years would be necessary to fill it from the rivers. There results from this calculation, that the quantity of water evaporated from the sea, and which the winds convey on the earth, producing rivulets, streams, and rivers, is from 20 to 21 inches in- a year, or about two thirds of a line each day ; this is a very trifling eva- NATURAL HISTORY. 51 poration when even doubled or trebled, in order to estimate the water which falls back into the sea, and which is not conveyed over the earth. Mr Halley has demonstrated that the vapours which rise above the sea, and which the winds convey over the whole earth are sufficient to form all the rivers, and to contain all the waters which are on the surface of the earth. In the old continent there are about 430 rivers, which fall directly into the ocean, or into the Mediter- ranean and Black Seas, and in the new continent, scarcely 180 rivers- are known, which fall directly into the sea. In this number, however, I have included none hut such as are as large as the river Somme in Picardy. All these rivers carry to the sea a great quantity of mineral and saline parts, which they have washed from the different soils through which they have passed. The particles of salt which are known to be easily dis- solved, are conveyed to the sea by the water. Some naturalist?, and among the rest Halley, have pretended that the saltness of the sea proceeded only from the salts of the earth, which the rivers transport thither. Others assert, that the saltness of the sea is as ancient as the sea itself, and that this salt was created only that it might not corrupt, but it may be well supposed that the sea is preserved from corruption by the agita- tions of the wind, and the flux and reflux, as much as by the salt it contains ; for when it is kept in a bar- rel, it corrupts in a few days ; And Boyle relates that a mariner becalmed for 13 days, found at the end of that time the sea so infected, that if the calm had not ceased, the greatest part of las people on board would have perished. The water of the sea is also .mixed with a bituminous oil, which gives it a disagreeable taste, and renders it very unhealthy. The quantity 52 NATURAL HISTORY, of salt contained in sea water is about l-40th part, and the sea is nearly equally saline throughout at top as at the bottom, under the line, and at the Cape of Good Hope, although there are several parts, as on the Mosambique G'oast, where it is salter than else- where. It is also asserted not to be so saline under the Arctic Zone, which may proceed from the great quantity of snow, and the great rivers which fall into those seas, and because the heat of the sun produces but little evaporation there, in comparison of that pro- duced in hot climates. There are rivers which lose themselves in the sands, and others which seem to precipitate into the bowels 'of the earth : the Guadalquiver in Spain, the river of Gottenburgh in Sweden, and the Rhine itself, lose themselves in the earth. It is asserted, that in the west part of St. Domingo, there is a mountain of a considerable height, at the foot of which are several large caverns that receive the rivers and brooks, whose fall is heard seven or eight leagues off. The rivers, however, which disappear in the earth are very few ; and they seem not to descend very deep. And it is probable that, like the Rhine, they lose themselves by dividing and disappearing through a large surface of sand, of which there are many examples in Afric a, Persia, Arabia, &c. The rivers of the north carry down to the sea pro- digious quantities of ice, which form those enormous masses so dangerous to the mariner. Those in the sea of Nova Zembla and in the straits of Waigat, come from the Oby, and, perhaps, from the Jenisca, and other great rivers in Siberia and Tartary : those of Hudson's straits, from Ascension bay, into which many rivers in North America empty them- NATURAL HISTORY. 53 selves ^ and those of Terra del Fuego, from the south- ern continent. If fewer of them are found in the northern coasts of Lapland than in those of Siheria and Waigat's straits, it is hecause all the Lapland rivers fall into the gulph of Bothnia, and none of them into the North Sea. The ocean surrounds the whole globe without any interruption of continuity, and the tour of the globe may be made by passing the point of South America, but it is not yet known whether the ocean surrounds the northern part of the globe in like manner ; and all mariners who have attempted to sail from Europe to China by the north-east or north-west, have equal- ly miscarried in their enterprises. The seas which are called Mediterranean, are pro- perly branches from the great ocean, by which they are supplied. Lakes differ from the Mediterranean seas, because they do not receive any water from the ocean ; for, on the contrary, if they have communi- cation with the seas, they furnish them with water ; thus the Black Sea, which some geographers have re- garded as connected with the Mediterranean, and con- sequently as an appendix of the ocean, is only a lake, because, instead of receiving water from the Mediter- ranean, it supplies it with some, and flows with ra- pidity through the Bosphorus into the lake called the sea of Marmora, and thence through the strait of the Dardanelles into the Grecian Sea. The water of the Black Sea is less clear, and much less saline than that of the ocean. No island is to be met with in this sea: tempests are very violent here, and more dangerous than in the ocean ; because the whole body of the waters being contained in a bason, which may be said to have no outlet, they have a kind of whirling motion 54 NATURAL HISTORY. when they are agitated, which strikes the vessels on every side with an intolerable violence. Next to the Black Sea, the greatest lake in the uni- verse is the Caspian Sea, \vhose extent in length from north to south is about 300 leagues, and scarcely more than fifty broad, computing it in a moderate propor- tion. This lake receives the Wolga, which is one of the greatest rivers in the world ; and also some other considerable rivers, as the Keir, the Fay, and the Gempo ; but what is singular is, that it does not re- ceive any on its eastern side throughout this whole length of 300 leagues. There are some small islands in the Caspian Sea, and its waters are much less sa- line than those of the ocean. In this sea no large vessels are used, as navigation is very dangerous in it, because it is shallow, and many banks and shoals are scattered under the surface of the water. There are lakes which, like pools, neither receive nor emit rivers. There are others which do receive rivers, and from which others run : and lastly, some which only receive rivers. The Caspian Sea and the lake Aral are of the last kind, they receive the waters of many rivers, and contain them. Thus the Dead Sea receives the Jordan, though no river issues from it. In Asia Minor there is a small lake of the same kind, which receives the waters of a river, the source of which is near Congi, and which, like the preceding, has no other mode than evaporation, to throw off the' waters it receives ; there is one much larger in Persia, on which the town of Maraga stands, its figure is oval and it is about ten or twelve kaj>ues long, by six or seven bro;ul ; it receives the river Taurus, which is not very considerable. There is also a similar small lal;e in Greece, about 12 or 15 leagues from Lepnnto, NATURAL HISTORY. 55 and there arc some of the same sort both in Africa and America. The most general and largest lakes, however, are those which, having received another river, or many small rivers, give rise to other great rivers. It is wor- thy of remark, that all lakes from which rivers derive their origin, all those which fall into the course of ri- vers, and which carry their water to them, are not sa- line. But almost all those, on the contrary, which receive rivers, without other rivers issuing from them, are saline, which seems to favour the opinion we have laid down on the subject of the saltness of the sea, for evaporation cannot carry off fixed salts, and con- sequently those which rivers carry into the sea remain in it; and although river water appears to taste sweet, we know that it contains a small quantity of salt, and in course of time the sea must have acquired a consi- derable degree of saltness, which must still continue to increase. Hence, in my opinion, the Black Sea, the Caspian Sea, the lake Aral, the Dead Sea, &c. are become salt. The lakes which are any ways remarkable are, the Dead Sea, the waters of which contain much more bitumen than salt ; this bitumen, which is called the Bitumen of India, is no other than the Asphaltum, which has induced some authors to denominate this sea Lake Asphallum. The land which borders on this lake contains a great quantity of bitumen, and may have applied the fables to this lake, which the poets feign of the lake Avernus, that no fish could live in it, and that birds which attempted to fly over it were suffocated. But neither of these lakes produce such mortal events ; fish live in both, birds pass over them, and men bathe in them without the least dan- 56 NATURAL HISTORY. ger. A petrifying lake in Iceland, is also mentioned, and the lake Neagh in Ireland, 1ms also the same pro- perty of apparently turning wood, &c. into stone ; but these petrifications are no other than incrustations like those made by the water of Arcueil. CHAP. III. OF TIDES, OF WINDS, ' REGULAR AND IRREGULAR — MONSOONS HURRICANES WHIRLWINDS WATER-SPOUTS. W ATER, like every other fluid, remains smooth and tranquil, unless put in motion by some foreign cause. All the waters of the ocean are collected in the lowest places upon the surface of the earth ; and hence the motion of the sea must proceed from exter- nal causes. The chief motion is that of the tides, which rise and fall alternately, and which produce a perpetual motion from east to west. These two mo- tions have an unvariable relation to the motions of the moon. During the full and new moons, this mo- tion from east to west is most observable, as well as that of the tides, which ebb and flow upon most coasts, every 6^ hours. It is always high tide when the moon arrives at the meridian ; and it is always low tide when the moon is at the greatest distance from it. The motion from east to west is perpetual ; because when the tide rises, it pushes an immense body of wa- ter from east to west, and the ebbing seems only to be occasioned by the smaller quantity of water which is then impelled westward. NATURAL HISTORY. 5? This motion is attended with the following circum- stances : 1st, It is more apparent at the full and new moon than at the quadratures. It is also more violent in spring and autumn than in any other season ; and is weakest at the solstices. This is owing to the com- bined attraction of the sun and irioon. 2d, The direc- tion and quantity of this motion is often varied by the winds, particularly by those which blow incessantly from the same quarter. 3d, It is worthy of remark, that when one part of a fluid is moved, the motion is communicated to the whole. During the tides, there- fore, a great part of the ocean is put in motion ; and the whole ocean, from top to bottom, is agitated at the same time. In order to throw a little more light upon this sub- ject, let us attend to the causes which produce the tides. We may therefore remark that the moon acts upon the earth by a power called gravity or attraction. This power penetrates the whole globe, and is exactly proportioned to the quantity of matter, and decreases as the squares of the distances increase. Let us now examine what effects this power must produce upon the waters when the moon comes to the meridian oi any place. •> The surface of the water immediately under the moon is therefore nearer that planet than any other part of the earth, consequently that part of the sea must be elevated towards the moon, and tire summit of this eminence must be opposite to the moon's centre. To produce this eminence, the waters upon the surface, as well as those at the bottom, contribute their share, in proportion to their distances from the moon, which acts upon them in the inverse ratio of the squares of their distances. Hence t! surface ef Vol. I. G S3 NATURAL HISTORY. this pait of the sea is first elevated ; the surface of the adjacent parts is also elevated, but not so much ; and the waters at the bottom of all these parts are raised by the same cause. Thus as the whole portion of water under the moon is raised, the waters at a distance, upon which no attraction is exerted, must necessarily rush forward with precipitation to supply the place of those which were drawn towards the moon. It is in this manner that the high tide is pro-* duced, which is more or less perceivable in different coasts, and which agitates the sea not only at the surface, but at the greatest depths. The ebb is a consequence of the natural disposition of the water, which when no lon'ger acted upon by the moon, sub- sides, and returns to occupy those shores from which it had been forced to retire by an external cause. Nothing is more irregular in our climates than the fiourse of the winds ; but there are countries where this irregularity does not exist, and others where the wind blows constantly in the same direction. There are several causes which influence the mo- tions of the air, but the most powerful is the heat of the sun, which by rarifying the air produces an influx of the cold air, which is a heavier fluid, and con- sequently presses in upon that which is rarified and light, and produces a stream or current air. In the torrid zone this effect is more uniformly manifest than in other parts of the world. In the regions near the equinoctial line a continual rarefaction is produced by the sun, and a constant current of air follows that lu- minary from east to west. This easterly wind blows so generally in the Pacific Ocean, that the ships which sail from Acapulca to the Philippines, perform a voyage of 2700 leagues in less than two month?. NATURAL HISTORY. 59 About 28 or 30 degrees on this side of the line the vest winds are equally constant, and for this reason the vessels returning from the West Indies to Europe do not pursue the same route as in going out. The winds which hlow continually for some months are generally followed by contrary winds, and mariners are obliged to wait for that which is favourable to them ; when these winds change, a calm or dangerous tempest ensues for several days, and sometimes for a month. These general winds, occasioned by the rarefaction of the atmosphere, combine differently by different causes in different climates. In part of the Atlantic Sea, under the temperate zone, the north wind blows almost constantly during the months of October, No- vember, December, and January, which is the reason why these months are the most favourable to embark from Europe to India, in order to pass the line by the favour of these winds ; and it is known, that ships which quit Europe in the month of March do not ar- rive sooner at Brazil than those which sail in the month of October. The North wind almost continually reigns during winter in Nova Zembla, and the other northern coasts. The south wind blows during the month of July to Cape Verd, when the rainy season, or winter of these climates sets in : at the Cape of Good Hope the north-west wind blows during the month of September : at Patna, in India, this north- west wind blows during the months of November, De- cember, and January, and produces heavy rains ; but the east wind blows during the other nine months. In the kingdom of Guzarat, and on the coasts of the neighbouring sea, the north winds blow from March till September; and during the other rnonthi 60 NATURAL HISTORY. of the year south winds almost always prevail. The Dutch, in order to return from Java, generally set sail in the month of January or February by an easterly wind, which is felt as far as 18 degrees northern lati- tude, after which they meet with south winds which carry them to St. Helena. In the Mediterranean, the winds blow from the land towards the sea at the sun's setting, and, on the con- trary, from the sea towards the land at its rising. Hence in the morning it is an easterly wind, and in the evening a westerly wind. The south wind, which is rainy, and which generally blows at Paris, Burgun- dy, and Champagne, at the beginning of November, and which gives place to mild and temperate breezes, produces the fair weather vulgarly called the summer of St Martin's. On the sea, the winds are more regular than at land, because the temperature of the sea is more equal than that of the land. For the temperature of the latter is altered by a variety of causes ; such as elec- tricity, volcanoes, exhalations from the earth, the explosion of meteors, &c. In general, on the sea, the east winds and those which come from the poles, are stronger than the west and those which proceed from the equators. On the land, on the contrary, the west and south winds are more or less violent than the east and north winds, ac- cording to the situation of the climates. Contrary currents are often observed in the air ; clouds that move in one direction, and others which are higher or lower than the first, proceed in a direc- tion perfectly opposite. This contrariety of motion however does not remain very long, and it is common- ly produced only by the resistance of some clouds to NATURAL HISTORY. 6t the action of the wind, and by the reaction of the di- rect wind, which reigns solely as soon as the obstacle is removed. The winds are more violent in mountainous places than in plains ; and the higher we ascend, the more the power of the wind increases, until we reach the common height of the clouds, which is about one quar- ter or one third of a league perpendicular height. Beyond that height, the sky is generally serene, espe- cially in summer, and the wind is said to be even im- perceptible on the tops of the highest mountains. A current of air increases in velocity, like a current of water, where the space of its passage is contracted The wind which is but slightly felt in a wide and o- pen plain, becomes violent in passing through a nar- row passage between two mountains, or between two lofty buildings ; and the point of the most violent ac- tion of the wind is above the structures or mountain straits. For the air being compressed by the resistance of these obstacles, has a greater mass, density and the same velocity subsisting : the effort or gust of wind, the momentum becomes much stronger ; this is the cause that near a church, or a castle, the winds seem to be much stronger than they are at a certain distance from these edifices. I have often remarked, that the wind reflected from a building that stands by itself, is stronger than the direct wind that produced it. And since I have endeavoured to discover the reason of this, I have been able to find no other than the a- bove. The impelled air compresses against the build- ing, and is reflected, not only with its former velocity, but also with a greater body, wliich, in fact, render*, its action much more violent. <62 NATURAL HISTORY. Particular winds, Aether direct or reflected, are more violent than those which are general. An uni- formly continued stream of air produces not such havo« as the fury of those winds which blow in sudden gusts. The predominancy of certain winds, in certain parts, has occasioned a general division of them into zones, though it is not to be understood that their effects ar« invariable. The east wind, which extends 20 or SO degrees on each side of the equator, occupies the torrid zone, and the north wind the frigid zones. With regard to the temperate zones, the winds which reign the:« are, if I may use the expression, only currents of air, whose motion is composed of those two winds whose direction tends to the west. And with respect to the westerly winds, whose direction tends to the east, anxl which often prevail in the temperate zone, whether in the Pacific or Atlantic oceans, they may be considered as winds reflected by the continents of Asia and A- merica, but originally derived from the east and north winds. The monsoons, or trade winds, which have an alter- nate motion, are subject to many deviations. Some con- tinue for a longer, some for a shorter time ; and they also differ in their extent, and in their degree of vio- lence. In the Indian ocean, for instance, between Af- rica and India, as far as the Moluccas, the east wind begins in January, and lasts till June. In the month of August or September, the contrary motion begins ; and the west winds reign during three or four months. In the intervals of these monsoons, that is, at the end of June, in the month of July, and beginning of Au- gust, there is no wind on that sja; but it L> infested with violent storms from the north. NATURAL HISTORY. 03 There are winds which may be regarded as peculiar to certain coasts ; for example, the south wind is al- most continual on the coasts of Chili and Peru. It be- gins about the 4-6th degree of south latitude, and ex- tends beyond Panama, which renders the voyage from Lima to Panama much easier performed than the return. The western winds blow almost continually, or at least very frequently, on the Magellanic coasts, and over the environs of the strait of Maire. The north and north-west winds prevail almost continually on the Ma- labar coast ; the north-west wind is also very frequent on the coast of Guinea ; and at a certain distance from that coast, in the open sea, we meet with the north- east wind very frequently. The westerly winds reign on the coasts of Japan, in the month of November and December. The alternate or periodical winds, which we have just been speaking of, are sea winds. But there are also land winds which are periodical, and return either at a certain season, or in certain days, or even at certain hours. On the Malabar coast, for example, from the month of September to April, a land wind blows from the eastern side : it generally commences at midnight and finishes at noon, and is not felt beyond 12 or 15 leagues from the coast, and from noon till midnight a weak sea wind reigns, which comes from the west. Oa the coast of New Spain in America, and on that of Congo in Africa, land winds reign during the night, and sea winds during the day. At Jamaica the winds blow from all quaiters at once during the night, which hinders vessels from either landing or setting out but in the day time. The winds are howevej- more irregular on the land than on the sea, and more irregular irr the higher lands 64 NATURAL HISTORY. tlfan in plains. The mountains not only alter the di- rection of winds, but they even produce winds, which are either constant or variable according to different causes. The melting of the snow, which is upon the mountains, generally produces constant winds, which sometimes remain very long. The vapours which are stopped by mountains, and which accumulate upon them, produce variable winds, very frequent in all climates. In the straits, on all the projecting coasts, at the extremity and in the environs of all pro- montories, peninsulas, and capes, and in all narrow gulphs, storms are frequent. But independent of these circumstances some seas are much more tempes- tuous than others. The Indian ocean, the Japan Sea, the Magellanic Sea, that of the African coast beyond the Canaries, and on the other side towards the coun- try of Natolia, the Red Sea, &c. are very subject to storms. The Atlantic ocean is more stormy than the ocean, which from its tranquillity, is called the Pac[fic. This ocean, however, is not absolutely tranquil, except between the tropics, and about the temperate zones ; and the more we approach the poles, the more we 'are subject to variable winds, whose sudden change often occasions tempests. All continents are subject to variable winds, which often produce singular effects. In the kingdom of Cas- simir, which is surrounded by the mountains of Cau- casus, a very sudden reverse of seasons is felt on mount Pirepenjale. In less than an hour's journey on it we pass from summer to winter. A north and a south wind, according to Bernier, blow perceptibly within 200 paces of one another. In the peninsula . of India, which is traversed from north to south by the mountains of Gate, the extreme heats of summer NATURAL HISTORY. 65 are felt on one side of the mountains, and all the rigours of winter on the other. The same phenomenon is also observed at Cape Rozalgate in Arabia, and on the island of Ceylon. In Egypt during summer, a south wind prevails which is so hot as to stop respiration ; and it raises so great a quantity of sand, that the sky seems covered with thick clouds. This sand is so fine, and driven with such force, that it penetrates every where, even into the closest coffers. When these winds last several days they occasion epidemical diseases, which are often at- tended with the most fatal consequences. The Cape of Good Hope is famous for its tempests, and the singular cloud which produces them. This cloud appears at first only like a small round spot in the heavens, called by the sailors the Ox's eye, and which I imagine appears so little from its exceeding great height. In Natolia, a cloud similar to the Ox's eye at the Cape, produces the same direful effects. In -the sea between Africa and America, especially under the equator and in the neighbouring parts of it, those tempests very often arise ; near the coast of Guinea sometimes three or four of these storms are formed in a day. They are occasioned and announced, like those of the Cape, by small black clouds. The rest of the sky is generally very serene, and the sea calm. The first blast which issues from these clouds is furious, and would sink ships in open seas, if they did not take the precaution to furl the sails. It is principally in the months of April, May, and June, that these tempest* are experienced on the Guinea sea, because no regular wind blows there during the season. All these tempests originate from winds which issue from a cloud, and their direction is either to the north Val. I. H 6t> NATURAL HISTORY. or south, north-cast or south-west, &c. But there ars tempests called hurricanes, which are still more violent, and in which the winds seem to hlow from all the coasts at once, with a circular motion, which nothing can re- sist. A calm generally precedes these horrible tem- pests ; but in an instant the fuiy of the winds raises waves as high as the clouds, borne parts of the sea cannot be approached, because they are continually in- fested with calms or whirlwind?. The Spaniards have therefore called these places calms and tornados. When from a sudden rarefaction, or any other cause, contrary currents of air meet in the same spot, a whirl- wind is produced. Perhaps the same effect takes place in another element, and gulphs or whirlpools may be no other than the eddies of the water formed by the action of two or more opposite currents. The Euripus, so famous for the death of Aristotle, alternately absorbs and rejects the water seven times' in twenty-four hours. This gulph is near the Grecian coast. The Charybdis, which is near the strait of Sicily, rejects and absorbs the water thrice in twenty-four hours. We are uncer- tain, however, with respect to the number of alternate motions in other whirlpools. The greatest known gulph is that of the Norway Sea, which is affirmed to be upwards of twenty leagues in circuit. It absorbs for six hours water, whales, ships, and whatever is near it, and afterwards returns them in six hours. A waterspout is no other than a whirlwind at sea. The vacuum which is occasioned by the meeting cur- rents makes the waters rise up in the form of a cylinder, or rather of an inverted cone. In the travels of Mr Thevenot there is a very minute and circumstantial ac- count of the formation of a waterspout, though there is reason to suspect that the relation is not without 'some optical deceptions. NATURAL HISTORY. 67 " The first, says tliis celebrated voyager, that we ,<;i\v, was on the northern coast, between us and the island Quesomo, about a gun-shot from the ship. We directly perceived water w hich boiled on the sur- face of the sea about a foot high ; it was whitish, and appeared above that height like a thick black smoke, so that it properly resembled some burning straw, which only smoked. It made a noise like that of a torrent which runs with much rapidity in a deep valley. But this noise was mixed with another, similar to the strong hissing of serpents or vipers. A little while afterwards we perceived something like a dark canal, or pipe, which bore a strong resemblance to smoke which ascends towards the clouds, revolved with great velocity. This pipe appeared to be about the thick- ness of my finger, and the same noise continued. The duration of this spout was about a quarter of an hour. We then perceived another on the south side of us, which began in the same manner as the preceding. Immediately a third and then a fourth sprung up, both to the west. Each of them appeared like heaps of smoking straw, and were accompanied with the same noise as the first. We afterwards saw three pipes cr canals, which descended from the clouds, on those places where the water was raised up, and each of them was as broad at the end fastened to the cloud, as the broad end of a trumpet, and resembled the teat (fan animal, drawn perpendicularly down by a heavy weight. These canals apuei'.rjd of a darkish wh.'tt, and were not straight, but crooked in some places- They even were not peipendicular; but, on the con- trary, from the clouds where they were joined to the parts which drew in the water, they were very much Lent.' And what is singular is, that the cloud which 68 NATURAL HISTORY. the second of these three was fastened to, having been driven by the wind, this canal followed it without breaking or quitting the place where it drew in the water, and passing behind the first canal, they were sometimes crossed like a St Andrew's Cross. At the beginning they were all three about the thickness of my finger, but afterwards the first of the three increased considerably. But the last which was form- ed scarcely remained longer than that which we saw on the north side. The second on the south side re- mained about a quarter of an hour, but the first on that side remained a little longer, and it was this which terrified us the most. At first its canal was as thick as my finger, afterwards as thick as my arm, then as my leg, and at last as the trunk of a large tree, which a man might compass with his arms. We distinctly perceived water through this transpa- rent body which ascended in a serpentine form. Sometimes it diminished a little in size, sometimes at top, and sometimes at bottom ; then it resembled ex- actly a soft tube with some fluid matter pressed with the fingers, either upwards, to make this liquor de- scend, or at bottom, to make it ascend. After thia it diminished so much that it was thinner than my arm; afterwards it returned as thick as my thigh, and then became very thin. At last, I saw that the water ele- vated on the surface of the sea began to lower, and that the end of the canal which touched it divided and' grew narrower, when a variation of the light removed It from our view."

TP 1 HE burning mountains called volcanoes, include in their bowels sulphur, bitumen, and other materials, which serve as aliment to a subterraneous fire, the effect of which is more violent than that of gunpowder or even of thunder. A volcano is a cannon of a very large size, the orifice of which is often more than half a league. This mouth vomits forth torrents of smoke, •flame, rivers of bitumen, sulphur, and melted metal, clouds of cinders and stones, and sometimes it ejects enormous rocks to many leagues distance, which would baffle the utmost efforts of human strength. The combustion is so terrible, and the quantity of burnt, melted, calcined, and vitrified materials which the mountain throws out, is so plentiful, that they enter cities, forests, cover the fields an hundred and two hundred feet in thickness, and form sometimes hills and mountains. The action of this fire is so great, the force of explosion so violent, that its re- action has been known to shake the earth, agitate the sea, overthrow mountains, and destroy the most solid towns and edifices, even to very considerable distances. The natives of Iceland imagine that the roarings of the volcano are the cries of the damned, and its erup- tions the effects of the rage and despair of these un- happy wretches. All these phenomena, however, are only the effects of fire and of smoke. In the bowels of mountains, 70 'NATURAL HISTORY. there are veins of sulphur, bitumen, and other inflam- mable substances, and also great quantities of pyrites, which ferment when exposed to thy air, or to moisture, en.l produce explosions in proportion to the quantity of inflammable matter they contain. A mixture of sulphur, of filings of iron, and of water, buried at a certain depth below the ground, will exhibit, in min.i- nture, all the appearcnces of a volcano. This mix- ture will soon produce explosions perfectly similar to those of burning mountains. There are three famous volcanoes in Europe, mount ^Etna in Sicily, mount Hecla in Iceland, and mount Vesuvius in Italy, near Naples. Mount JEtna has burnt from time immemorial. Its eruptions are very violent, and the matters it throw's out are so plentiful that they may be dug to the depth of 68 feet, where we meet with marble pavement, and tie vestiges of an ancient town which has been covered and buried under this thickness of matter ejected from the mount, in the same manner as the city of Herculaneum has been covered by the matter thrown out from Vesuvius. New mouths of fire were formed in 1650, iCfip, and at other times. We see the flame and smoke of this volcano from Malta, wliich is about 60 leagues distant from it ; it smokes continually, and it sometimes vomits flames and matters of every kind with impetuosity. In 1537, there was an eruption of this volcano, which occasioned an earthquake in Sicily for 12 days, and which over- threw a very great number of houses and structures. It ceased only by the opening of a new lire mouth, which burnt every thing for rive miles in the environs of the mountain. The cinders thrown out by the volcano were to abundant, and ejected with so much force, that they wove driven as far as Italy ; and vessels wliich NATURAL HISTORY. 71 Y.-erc depu1 i.-,l lo .some distance from Sicily were incom- moded by them.

These two vents always •moke, but fire is never seen to issue from them, but du- ring the time of eruptions. It i* pretended that stones ore found which it has thrown out to the distance of b'0,000 feet*. One of the last and most violent eruptions of mount Vesuvius was in the year 1?37- The mountain vomit- ed by divers mouths large torrents of burning metallic matters, which dispersed themselves over the country and into the sea. Mons. de Montealegre, who com- municated this relation to the Academy of Sciences, observed with horror one of these rivers of fire, and saw its course for six or seven miles till it reached the sea. Its breadth was sixty or seventy feet, its depth, twenty- five or thirty palms, and in certain bottoms or valleys, 220 ; the matter which flowed was like the scum which issues from the furnace of a forge. In Asia as well as in America there are a great num- ber of volcanoes; but there is nothing peculiarly worthy of remark in any, except the violence with which some of them occasionally emit the burning matters with which they are charged. Near Fez in Africa, there is a mountain, or rather a cavern, called Beniguazevel, which always emits smoke, and sometimes flames. One of the islands of Cape Verd, called the island of Fuogo, is only a larga » Sea a most interesting description of this celebrated mountain iii a» • Mid <'iitrrta.i:;ii!g production iutilled, •• Bntlo.i's Tour tliroo^K Ski!) and MaXa." 72 NATURAL HISTORY. mountain which burns incessantly. This volcano, like the rest, throws out many cinders and stones ; and the Portuguese, who have attempted several times to erect habitations in this island, have been constrain- ed to abandon this project, through the dread of the ef- fects of the volcano. The Canaries, the Peak of Tene- riffe, and some of the highest mountains in the world, throw out fire, cinders, and large stones ; from the top, rivulets of melted sulphur flow, which are distinguish- able at a great distance. The matters which volcanoes throw out, generally come forth in the form of a tor- rent of melted minerals, which inundates all the envi- rons of these mountains. These rivers of liquified matters extend even to considerable distances, and when cooled, form horizontal or inclined strata, which for position are like the strata formed by the sediment left by the waters. But it is very easy to distinguish the strata produced by the expansion of matters thrown out by volcanoes, from those which have the sediment of the sea for their origin. 1. Because these strata are not of an equal thickness: 2. Because they contain only matters which are easily perceived to have been calcined, vitrified, or melted, and because they do not extend to any great distance. When coal mines are opened, which are generally met with in argillaceous earth at a great depth, it sometimes happens that these matters have taken fire. There are even mines of coal in Scotland, Flanders, &c. which have burnt for a number of years. The communication of the air suffices to produce this effect, but the fires which are lightes ed in these mines, produce only slight explosions, and do not form volcanoes, because all being solid and full in these places, fire cannot be excited, like that of vol- canoes, in which there are cavities and void place* NATURAL HISTORY. ?$' where the air penetrates, which must necessarily ex- tend the conflagration and augment the action of the fire, to the point in which we see it when it produces the terrible effects we have taken notice of. There are two kinds of earthquakes, the one occa- sioned by the action of subterraneous fires, and the ex- plosion of volcanoes, which are only felt at small dis- tances, and at the time when volcanoes act, or before they open. When the matters which form subterran- eous fires, ferment, heat and inflame, the fire makes an effort on every side, and if it does not find a natural vent, it raises the earth and forces a passage for itself by throwing it out, which produces a volcano, whose effects are repeated, and last in proportion to the quan- tity of inflammable matters. If the quantity of mat- ters which take fire is not considerable, a commotion or an earthquake may ensue, without a volcano being formed. The air produced and rarefied by the subter- raneous fire, may also find small vents, by which it will escape, and in this case there will be only a shock with- out any eruption or volcano. But when the inflamed matter is in a great quantity, and confined by solid and compressed matters, then a commotion and volcano a- rises : but all these commotions form only the first kind of earthquakes, and can enly shake a small space of ground. A very violent eruption of mount ^tna will occasion, for example, an earthquake through the whole island of Sicily ; but it will never extend to the distance of three or four hundred leagues. When any new mouth is formed in mount Vesuvius, there are earthquakes at Naples and in the neighbourhood of the volcano : but these earthquakes have never shook the Alps, and are not communicated to France or to other countries remote from the source of the phenomenon. Vol. I. I 74 NATURAL HISTORY. But there is another kind of earthquake, very di£* ferent in its effects, and perhaps in its causes. There are earthquakes too which are felt at great distances, and which shake a long course of ground, without any new volcano or eruption appearing. To understand rightly what may be the causes of this kind of earthquake, it must be remembered, that all inflammable matters capable of explosion, produce like gun-powder, by inflammation, a great quantity of air ; that this air produced by fire is in a state of very great rarefaction ; and that, by a state of compression in which it is found in the bowels of the earth, it must pro- duce very violent effects. Let us therefore suppose, that, at a very considerable depth, as at about one or two hundred fathoms, pyrites, and other sulpherous matters are to be met with ; and that, by the fermen- tation produced by the filtration of the water, or other causes, they inflame. At first, these matters are not dis- posed regularly by horizontal strata, as the more ancient matters are, which have been formed by the sediment of the waters. On the contrary, they are formed in perpendicular strata, in caverns at the foot of these clefts, and in other parts where the water can act and penetrate. These matters inflaming, will produce a great quantity of air or vapour, the spring of which, compressed in a small space, like that of a cavern, will not shake the earth immediately above, but will search for passages, in order to make its escape. It will there- fore naturally force its way through those parts where it meets least obstruction, and will therefore proceed through the interstices between the different strata, or through any channel or caverns through which it can find a passage. This subterraneous air or vapour will therefore produce in its passage a noise and motion pro- NATURAL HISTORY. 75 portioned to its force and to the resistance it meets with. And these effects will continue till it finds a vent, perhaps in the sea, or tiil it has diminished its force by being greatly expanded. This explanation corresponds entirely with all the phenomena which are observed re- specting earthquakes. They proceed with a wave-like motion, and are felt at different places, not at the same instant, but at different times, in proportion to the distance. We can also confirm what has been advanced, by connecting it with two other circumstances, It is well known that mines exhale vapours, independent of the wind produced by the current of the water; we often see currents of unhealthy air and suffocating vapours'. We also know that there are holes, abysses and deep lakes in the earth, which produce winds, like the lake Boleslaw in Bohemia, &c. From history we have innumerable instances of the dreadful and various effects of these terrible phenomena. Pliny, in his first book, chap. 84, relates, that in tlw reign of Tiberius, an earthquake happened, which over- threw twelve towns in Asia ; and in his second book he mentions an earthquake which overthrew 100 towns in Lybia. In the time of Trajan, the town of Antio- chus, and a great part of the adjacent country, were swallowed up by an earthquake ; and in the time of Justinian, in 528, it was again destroyed by a second, with upwards of 40,000 of its inhabitants. And, sixty years after in the time of Saint Gregory, it felt the ef- fects of a third earthquake, with the loss of 60,000 of its inhabitants. In the time of Saladin, in 1182, most of the towns of Syria and Jerusalem were distroyed by the same cause. In Calabria and Poh, there have been more of them than in any other part of Europe. 76 NATURAL HISTORT. In the time of Pope Pius XI. all the churches ami Palaces of Naples were overthrown, and ahove 30,000 of its inhabitants killed. In 1 629, there were earth- quakes in Pola, which destroyed 7000 persons ; and in 1638, the town of Saint Euphemia was swallowed up ; and there -remains only a stinking lake in its place. Ragusa and Smyrna were also almost destroyed. There fras an earthquake in l6'92, which extended into Eng- land, Holland, Flanders, Germany, and France ; it was chiefly felt on the sea coasts and rivers, and extended to a space of at least 2600 leagues square, On the l6th of June, 1628, there was so horrible an earthquake in the island of St Michael, that the Sea near it opened, and in one place, where it was more than 1 50 fathoms deep, threw up an island more than a league and a half long, and upwards of 6'0 fathoms high. Another earthquake happened in lfi91» which be- gan the Kith of July, and lasted in the island of St Michael till the 12th of the following month. Tercera and Fayal were agitated the next morning with so much violence, that they appeared to move ; but these frightful shocks returned only four times ; whereas, at St Michaels, they did not cease a moment for 15 hours. The islanders having quitted their houses, which they saw fall before their eyes, passed all that time exposed to the injuries of the weather. A whole town, named Villa Franca, was overthrown to its very foundation, and most of the inhabitants buried under its ruins. Several plains rose into hills • and some mountains be- came flat. A spring of water issued from the earth, which flowed for four hours, and which appeared dry all on a sudden. The air and sea, still more agitated, resounded with a noise like the roaring of a number of wild beasts. Many per?ons died with the fright, and NATURAL HISTORY. 77 the ships in the ports suffered dangerous shocks ; and those which were at anchor, or under sail, 20 leagues distant from the islands, sustained great damage. In the year K)-t5 the mountain of the island of Ma- chian split with terrible reports, by an earthquake ; and so many fires issued through this opening, that they consumed many negro-yards, and all that was in them. This prodigious crack is still apparent; and it is called the path of Machian, because it descends from the bottom like a road hello wed out, but which at a dis- tance appears like a path. At sea the shock of an earthquake is felt at a consi- derable distance. M. Shaw relates, that in 1721, being on board the Gazelle, an Algerine vessel, mounting 50 guns, three violent shocks were felt one after the other, as if every time a weight of 20 or 30 tons had been thrown on the ship. This happened in a part of the Mediterranean which was 200 fathoms deep. In countries subject to earthquakes, it happens, when a new volcano is formed, earthquakes cease, and are only felt in the violent eruptions of the volcano, as is observed in the island of St Christopher. New islands are produced, either suddenly by the operation of subterraneous fires, or slowly by the accu- mulated sediments of water. Seneca informs us, that in his time the island of Therasia suddenly emerged from the sea; and Pliny relates, that thirteen islands arose all at once from the bottom of the Mediterranean. Upon this subject, however, we have some facts ir.ore recent, and less involved in obscurity. The 23d of May, 17075 at sun rising, near this same island of Therasia, or Santorini, something was seen like a floating rock in the sea, Some persons, ex- cited, by curiosity, approached it, and found this shoal. 78 NATURAL HISTORY. which had issued from the bottom of the sea, to increase under their feet ; and they brought with them the pu- mice stone and oysters, which the rock still had attach- ed to its surface. There was a slight earthquake at Santorini two days before the growth of this shoal. This new island increased considerably till the 14th of* June, without any accident, and was then half a miie round, and from twenty to thirty feet high. The earth was white, and bordered a little on argillaceous, after which the sea was still more agitated ; vapours arose, which infected the island Santorini; and, the iCth, 17th, or 18th of July, rocks were seen to issue at one time from the bottom of the sea, all of which seemed to unite into one rock. All this was done with a dis- mal noise, which continued upwards of two months, with flames that rose from the new island, which still kept itself increasing in circumference and height ; and the explosions always threw out rocks and stones to the distance of seven miles. The 10th of October, 1720, near the island Tercera, a very considerable fire arose out of the sea. Mari- ners having been sent to examine it, they perceived, the 19th of the same month, an island which appeared to be covered with fire and smoke, and a prodigious quantity of cinders thrown to a distance, as from a volcano, and accompanied with a noise similar to that of thunder. The historian of the French Academy in relating' this event, remarks, that, after an earthquake in the island of St Michael, a torrent of fire appeared be- tween It and the island Tercera, which gave birth to two new rocks. And next year, the same historian gives the following account: NATURAL HISTORY. 79 Ct M. de I'lsle has informed the Academy of several tc particulars, which were communicated to him in a '• letter, from M. de Montagnac, consul at Lisbon, " concerning the new island among the Azores. On "the 18th of September 1721, M. de Montagnac's " vessel was moored off the Fortress of St Michael, " and he procured from the Pilot of the port the fol- " lowing intelligence: " On the 7th, of December, 1720, at night, a great "earthquake happenedin Tercera andSt Michael, which " are distant about 28 leagues from one another, and a '•' new island emerged from the sea. It was, at the same " time, observed that the island Peak, thirty leagues " distant, which ejected flames, was extinguished. But " a continual thick smoke proceeded from the new is- " land, which was distinctly perceived by M. de Mon- " tagnac, as long as he stopped in that part. The pilot " assured him, that he had sailed round the island, and " approached it as near as he could with safety. He " sounded on the south side of it with a rope of 60 " fathoms, but found no bottom. On the west side, ' ' the water appeared to be mixed with white, blue, and " green ; and at the distance of two miles, it seemed " to be shallow and boiling. On the north-west, the " side from which the smoke issued, he found, at 15 " fathoms, a bottom of coarse sand. He threw a stone " into the sea, and at the place where it fell, he observed the " water boil and mount into the air with great velocity. " The bottom was so hot as to melt a piece of suet " that had been fastened to the end of the plumb line. " The pilot also observed smoke to issue from a small " lake, in the midst of a sandy plain. " We have since learned from M. Adrien, the French " consul at St Michael, dated, March 1 722, that the 80 NATURAL HISTORY. " new island is near on a level with' the water, and " that it will probably soon disappear. " From these and several other similar facts, it ap- " pears, that inflammable bodies exist under the bot- " torn of the sea, and that they sometimes produce fl violent explosions." On the whole, however, the islands produced by the •action of fire and earthquakes, are but few, and these events are seldom ; but tiiere are an infinite number of new islands produced by the mud, sand, and earth, •which the rivers, or the sea carry and transport into different places. At the mouth of all rivers, masses of earth and banks of sand are formed, whose extent often become considerable enough to form islands of a mode- rate size. The sea retiring from certain coasts, leaves the parts highest from the bottom naked, which form so many new islands, And likewise, by extending it- self on certain shores, it covers the lowest parts, and leaves the highest, which it could not surmount, to ap- pear above the surface of the water, which form so many more islands. In consequence of which, it is remarked, that there are very few islands in the mid- dle of the sea, and that they are almost all in the neighbourhood of the continents, where the sea formed them, either by retreating from, or approaching towards, these different countries. Water and fire, whose natures are different, and, even contrary, produce what, at least appears to us to be similar effects. Water, as has been observed, has produced mountains, and formed most islands. There are likewise caverns, clefts, holes, gulphs, &c. some of which owe their origin to subterraneous fires, and others to water. NATURAL HISTORY. si Saint Patrick's cavern, in Ireland, is not so consi- derable as it is famous. It is the same with the Dog's Giotto in Italy, and with that which throws out fire in the mountain of Benigauzeval, in the kingdom of Fez. One of the most remarkable and largest caverns known, is that of Antiparos, which is computed to be three hundred fathoms deep from the surface of the earth ; but the grotto appears to be forty fathoms high by fifty broad. It is filled with large, beautiful sta- lactites, of various forms, both en the roof of the vault and at the bottom In that part of Greece, called Livadia, (the Achaia of the ancients) there is a large cavern, in a mountain which was formerly very famous for the oracles of Trophonius, between the lake Livadia and the adjacent sea. There are forty subterranean passages across the rock, under a lofty mountahij through which the waters of the lake continually flow. In the month of June, 1714, apart of the mountain of Diableret in Valois, fell suddenly, between two and three o'clock in the afternoon. The sky was very serene ; the mountain was of a conical figure, and destroyed fifty-three huts belonging to the boors, and crushed to death fifteen people, and above t\vo hundred cattle, ar>d covered a square league with its ruins. A profound darkness was occasioned by the dust. The heaps of stones thrown together stopped the current of the wa- ter, which formed new and very deep lakes. In all of which, however, there was not the least trace of bitu- minous matter, sulphur, lime, nor consequently any subterranean fire, and it appeared that the base of this great rock was worn away, or reduced to dust. V«l. T. K «2 NATURAL HISTORY. We have a remarkable example of these sinkings near Folkstone, in the county of Kent. The hills in its en- virons have sunk gradually, by an imperceptible motion, and without any earthquake. These hills internally are rocks of stone and chalk. By this sinking, they have thrown into the sea rocks and earths which are adjacent to it. When the waters on the surface of the earth cannot find vent to flow, they form morasses and hogs. The most famous morasses in Europe, are those of Muscovy at the source of Tanais ; those of Finland, where are the great morasses of Savolax and Enasak. There are also some in Holland, Westphalia, and many other low countries. In Asia, the morasses of the Euphrates, those of Tartary, and the Palus Meotidis ; neverthe- less, in general there are fewer of them in Asia, and Africa than in Europe. But America may be said to be one continued morass through all its plains. This great number of morasses is a proof of the modern date of the country, and of the small number of inhabitants, and still more of their want of industry. To give an idea of the quantity of earth which the rain detaches from the mountains and carries along with it into the valleys, we can quote a circumstance related by Dr Plot. In his Natural History of Staffcrdshire, he observes that eighteen feet deep in the earth several pieces of money coined in the reign of Edward V. have been found ; i. e. two hundred years before his time.' Hence this ground, which is boggy, has increased above a foot in eleven years, or an inch and a twelfth every year. We can still make a similar observation on trees buried at seventeen feet depth, below which medals of Julius Caesar have been found. Thus the brought from the tops of mountains into plain* NATURAL HISTORY. 99 by running waters, fail not to increase the elevation of the ground of plains very considerably. In the city of Modena, and four miles round, what- ever part is dug, when we reach the depth of sixty- three feet, and bore five feet deeper with an augur, the water springs out with such force, that, the well is filled in a very short space of time. This water flows continually, and neither diminishes nor increases by the rain or drought. What is remarkable in this ground is, that when we reach the depth of fourteen feet, we find pavements, and other ruins of an ancient town, as boards, houses, different pieces of mosaic work, &c. Below these we find a very solid ground, which is thought never to have been stirred ; yet be- low it we find a moist earth mixed with vegetables. And at twenty-six feet, are entire trees, as nut-trees, with nuts on them, and a great quantity of branches and leaves of trees. At twenty-eight feet depth, we meet with a friable chalk, mixed with many shells ; and this bed is eleven feet in thickness ; after which, we again meet with vegetables, and so on alternately chalk and earth mixed with vegetables, to the depth of sixty-three feet. At which depth is a bed of sand mixed with some gravel arid shell, like those formed on the coasts of the Italian sea. These successive beds of fenny or marshy earth and chalk, are always found in the same order, wherever we dig ; and very often the augur racels with large trunks of trees, which it bores through, but which give great trouble to the workmen ; bones, coals, flint, and pieces of iron are also found. Ramaz/ini, who relates these cir- cumstances, thinks that the gulf of Venice formerly extended beyond Modena, and that perhaps by ti»e in- undations of the sea this ground has been formed* 84. NATURAL HISTORY. It is evident, that considerable changes have taken place on the surface of the globe, not only by the action of fire, but also by water. The sea, from various circumstances, has repeatedly changed its bed. Authors have suspected, that the island of Great Britain was formerly united to the continent of France. On the coast of France, England, Holland, and Ger- many, the sea has retreated in many parts. In Italy, a considerable tract of territory has been gained by the retreating of the ocean ; and Ravenna, which was formerly a sea-port of the Exarques, is no longer a maritime town. On the mountain of Stella, in Portugal, is a lake in which the wrecks of ships have been found, not- withstanding this mountain is more than twelve leagues distant from any sea. Sabinus, in his commentaries on Ovid's Metamorphoses, says, that from the monu- ments of history it appears, that in the year 14GO, a whole ship, with its anchors, was found in a mine of the Alps.

ANALOGIES BETWEEN ANIMALS AND VEGETABLES—- ON THE NATURE OF MAN OF INFANCY MAN- HOOD EXTENT OF HUMAN LIFE OF THE SENSES— ANECDOTES ILLUSTRATIVE OP THIS SUBJECT, j*\MONG the vast variety of objects in which the surface of this globe abounds, animals hold the first rank, both on account of the relation which they bear to man, and of thoir superiority over vegetable and NATURAL HISTORY. 85 inanimated nature. The senses, the figure, and the motions of animals, afford them a more intimate con- nection with surrounding objects than vegetables pos- sess. The latter, however, from their expansion, their growth., and the variety of parts which compose them, are more intimately related to external objects than minerals or stones, which are perfectly inert, and des- titute of every vital principle. It is this number of relations alone which renders the animal superior to the vegetable, and the vegetable to the mineral. What a variety of springs, of powers, and of me- chanical movements, are included iu that small portion of matter of which the body of an animal is composed ! What a number of relations, what harmony, what cor- respondence among the different parts ! How many combinations, arrangements, causes, effects, and prin- ciples, all conspiring to accomplish the same grand design ! But how admirable soever this work may appear, the greatest miracle is not exhibited in the individual. It ii in the successive renovation, and in the continued duration of the species, that nature assumes an aspect inconceivable and astonishing. This faculty of repro- duction, which is peculiar to animals and vegetables, must, with regard to us, continue to be so profound a mystery, that we shall probably never be able to inves- tigate it with sufficient accuracy. Even inanimated bodies have some properties, and the most imperfectly organized matter possesses many relations with the other parts of the universe. We will not assert, however, that matter, undc-r whatever form it appears, is conscious of its existence, and of its relative powers. We shall only say, that being ignorant of th > extent of our own con- 86 NATURAL HISTORY. nections with external objects, we will not hesitate to pronounce inanimated matter to be infinitely more so. Besides, as our sensations have not the most distant resemblance to the causes that produce them, analogy obliges us to conclude that dead matter is neither en- dowed with sentiment, sensation, nor even with a con- sciousness of its OAvn existence. With inanimated matter, therefore, we have no other relations than what arise from the general properties of bodies, extension, impenetrability, gravity, &c. But as relations purely material make no impression on us, and as they exist entirely independent of us, they cannot be considered as any part of our being. Our existence, therefore, is an effect of organization, of life, of the soul. Matter, in this view, is not a prin- cipal but an accessary. It is a foreign covering, unit- ed to us in a manner unknown. But in order to give a more perfect idea of the nature of man, let us trace him through the different stages of his existence. At its birth, the infant is exposed to a new element, the air. What the sensations are on the admission of this element into the lungs, it is impossible to conjec- ture ; but, from the cries of the infant, we have reason to believe that it is attended with pain. The eyes of an infant are indeed open, but they are dull, and ap- pear to be unfitted for the performance of any office whatever; and the outward coat of them is wrinkled. The same reasoning will apply to most of the other ' senses. It w not till after forty days that it begins to smile ; nor is it till then that it begins to weep. Its former sensations of pain are unaccompanied with tears. The size of an infant born at the full time, is twenty- one inches, though some do not exceed fourteen ; and it generally weighs twelve,' and sometimes fourteen NATURAL HISTORY. 87 pounds. The form of the body and members of a new-born infant are by no means perfect. At the end of three days there generally appears a kind of jaun- dice ; and at that time, there is generally milk in the breast of the infant, which is squeezed out with the fingers. The skull of infants is not completely formed. In the language of the nursery, the head is open in a particular part ; that is, the skull bones have not yet grown far enough to meet. In this opening, a palpi- tation may sometimes be discovered ; and the beating of the arteries may always be felt. Above this open- ing, a species of scurf appears, which is rubbed off with a brush. In this country, infants, as soon as born, are injudiciously and unnaturally laced with ban- dages, which renders them unable to move a single joint. Nations which we call barbarous, act more ra- tionally in this respect. The Siamese, the Indians, the Japanese, the Negroes, the Savages of Canatla, of Virginia, of Brasil, and almost all the inhabitants of South America, lay their infants naked in hanging beds of cotton, or in cradles lined with fur. Infants sleep much, but their sleep is often inter- rupted. They ought to have the breast every two hours in the day, and in the night as often as they awake. It is of great importance to keep children clean and dry from their excrements. The American Indians, who cannot change their furs as frequently as we can do our clothes, put under them the dust of rotten wood, and renew it as often as it gets damp. Great evils ensue from the negligence of nurses. Infants are sometimes left to cry for a con- siderable time, which often occasions diseases, or, at least, throws them into a state of lassitude, which de- ranges their constitutions. To palliate this they are 88 NATURAL HISTORY. sometimes put into a cradle and rocked to sleep which may occasionally derange the stomach and head. Before children are put up into the cradle, we ought to be certain they want nothing, and when they are rocked, it ought never to be with such violence as to stun or stupif'y them. The eyes of children are always directed towards the light, and if one eye only be directed to it, the other will probab'y become weak ; both eyes ought, therefore, to be equally shaded, or equally exposed. Squinting is commonly the effect of injudicious treatment in this respect,. For the first two or three months the diet of the in- fant Ought chiefly to be confined to the'mother's milk. The eight incisores, or fore-teeth, appear first. They are produced generally by pairs, and from two- months old to ten or twelve. The four canini (or dog- teeth) appear commonly about the 9th or 10th month. About the close of the first, or in the course of the second year, sixteen other teeth appear, called niolares, or grinders. In the 5th, 6'th, or 7th year, the fore- teeth, and the dog-teeth, and the first six of the grinders, naturally shed, and a new set appears. At the age of puberty, or later, the denies sapiential, or wise teeth, appear. Women are said to have fewer teeth than men. The hair of most infants is exceedingly light, al- most white. When a child is suffered to cry violently, and too long, it is in danger of a rupture, but the early application of bandages or trusses will frequently remove the complaint. The frame of infants is less sensible of cold than during any other season of life. The pulse is strong, and it is therefore fair to conclude, that the internal heat is considerable. Small animals, for the same NATURAL HISTORY. 89 reason, have more heat than great ones ; because the action of the heart and arteries increases in proportion to the comparative smallness of the animal. Till the aga of three years the life of infants is extremely pre- carious ; in the course of the ensuing second or third years it becomes mere certain, and at six or seven a child has greater probability of living than at any other period of life. It is remarked, that of a certain number of children born at the same time, above a fourth die in the first year ; above a third in twa years, and at least one half in three years. By other calculations, it appears that one half of the children born at the same time are not extinct in less than se-« ven or eight years. At twelve or fifteen months infants begin to lisp* A is the vowel which they pronounce with most ease. Of the consorlants, B, M, P, T, are most easy. In every language, therefore, Baba, Mama, Papa, are the first words that children learn. Some children pronounce distinctly in two years, though the gene- rality do not speak for two years and a half. Some young persons cease growing at fourteen or fifteen, while others continue their growth to twenty- two or twenty-three. In men the body attains, its perfect proportion at the age of thirty, and in women sooner. The persons indeed of women are generally complete at twenty. The distance between the eyes is less in man than in any other animal ; in some creatures, in fact, the eyes are at so great a distance, that it is impossible they should ever view the same object with both eyes at once. Men and apes are the- only animals that have eye-lashes on the lower eye- lid. Other animals have them only on the upper one. Vol. I. L 90 NATURAL HISTORY. The upper eye-lid rises and falls, the lower has scarce- ly any motion. The ancients erroneously considered the hair as a kind of excrement, and believed that, like the nails, it increased by the lower part pushing out the extremity. But the moderns have discovered that every hair is a tube, which fills and receives nutriment like the other parts of the body. The roots, they observe, do not turn grey sooner than the extremities, but the whole changes its colour at once. We have known persons the hair of whose heads have become grey in one night. There is no part of the body which has been subject to such changes of fashion as the hair and the beard. ... Some people, and among others the Turks, cut the hair off their heads, and let their beards grow. The Europeans, on the contrary, shave their beards, and wear their hair. The negroes shave their heads in figures at one time, in stars at another, in the manner of friars; and still more commonly in alternate stripes ; and their little boys are shaved in the same manner. The Talapoins of Siam, shave the heads and the eye- brows of such children as are committed to their care. Every nation seems to have entertained different pre- judices, at different times, in favour of one part or another of the beard. The neck supports the head, and unites it to the body. This part is much more considerable in the greater number of quadrupeds, than in man. But fishes and other animals that have not lungs similar t!o ours, have no neck whatever. Birds, in general, have the neck longer than any other kind of animal. Those which have short claws, have also short necks ; those on the contrary, that have them long, are found to have the neck in proportion. NATURAL HISTORY. 91 The human breast is outwardly formed in a very different manner from that of other animals. It is larger in proportion to the size of the body ', and none but man, and such animals as make use of their fore feet as hands, such as monkeys, bats, and squirrels, are found to have those bones called clavicles, or, as we usually term them, collar-l ones. The breasts in women are larger than in men ; however, they seem formed in the same manner ; and, sometimes, milk is found in the breasts of men, as well as in those of wo- men. Bird?, and all other oviparous animals, have no teats ; but viviparous fishes, as the whale and the dol- phin, have both teats and milk. There is little known exactly with regard to the proportion of the human figure ; and the beauty of the best statues is better conceived by observation than by measurement. Some who have studied after the an- cient masters, divide the body into ten times the length of the face, and others into eight. They tell us, that there is a similitude of proportion in different parts of the body : thus, that the hand is the length of the face ; that the thumb is the length of the nose ; that the space between the eyes is the breadth of the eye ; that the breadth of the thickest part of the thigh is double that of the thickest part of the leg, and treble the thinnest, &c. The strength of man is very considerable when ma- tured by practice. We are assured that the porters of Constantinople carry burthens nine hundred pounds weight. And M. Desaguliers mentions a man in an upright posture, who, by distributing a certain number of weights, in such a manner that every part of his bo- dy bore its share, was able to support a weight of two thousand pounds. ,92 NATURAL HISTORY. The strength of a man may be still farther estimate J by the continuance of his labour, and by the agility of his motions. Men, who are exercised in running, out- strip horses, or at least continue their speed for a greater length of time. In a journey, after a man and a horse have proceeded together for several days, the former will be fresh when the latter will be quite tired. The royal messengers of Ispahan run thirty-six leagues in fourteen or fifteen hours. Travellers assure us, that the Hottentots outrun lions in the chace ; and that the savages who hunt the elk, pursue this animal, which is as fleet as a stag, with such speed that they take it. The civilized man is ignorant of his own strength, nor is he sensible how much he loses of it by effeminacy, and how he might add to it by the habit of vigorous exercise. To complete our description of man, it will be proper to investigate the human countenance, as it appears among ourselves, when agitated by the passions. In affliction, in joy, in love, in shame, in compassion, the eyes are apt to be swelled, and as it were obscured by an overflow of tears. The effusion of these is always ac- companied with a tension of the muscles of the visage, by which there is occasioned an opening of the mouth. At the same time, the natural moisture in the nose be- comes more copious, and, by internal passages, mixes itself with the lachrymal moisture ; which, however, flows only at intervals, not always. The two corners of the mouth are lowered by grief, the under lip is erected, the eye-lid is half closed, the pupil of the eye is raised, and almost covered with the eye-lid. And the other muscles of the face are so much relaxed, that the space betwixt the mouth and the eyes is larger than ordinary, and consequently the counte- nance assumes a lengthened appearance. NATURAL HISTORY. 93 Fear, terror or horror, wrinkles the forehead, raises the eye-brow, extends the eye-lids as much as possible, and discovers a part of the white of the eye over the pupil, which is lowered, and somewhat concealed by the inferior eye-lid. Tiie rnouth, at the same time, is widely opened, and the lips being separated, both the upper and under teeth appear. Contempt or derision raises the upper lip on one side, and on the other there is a little motion, as if in order to smile. The nose is shrivelled on the same side on which the lip is raised, and the corner of the mouth is extended. The eye on the same side is almost shut, while the other is open as usual, but the pupil of each is lowered,' as when one looks downward. By jealousy, malice, and envy, the "eye-brow falls down, and is knit, the eye-lid is raised, and the pupil lowered. The under-lip is raised on each side, while the corners of the mouth are rather lowered, and the middle of the under-lip is raised, in order to join the middle of the upper one. The two corners of the mouth are extended by laugh- ter, and somewhat raised. The upper part of the cheeks is raised, and the eyes are more or less closed. The upper lip too is raised, while the under one is lower- ed ; and, in moderate laughter, the mouth is opened, and the skin of the nose is contracted. Where there is a good natural constitution of the body, it is not impossible, by moderating the passions temperance and sobriety, to extend the period of life for a few years. But even of this there seems to be an uncertainty ; for if it is necessary that the body should employ its whole strength, that it should consume whatever it is capable of consuming, that it should undergo every possible ex- 94, NATURAL HISTORY. ercise, whence could any benefit accrue from regimen, and from abstinence ? Men, no doubt, there are who have outlived the usual period of human existence. Not to mention Parr, who lived to the age of one hundred and fifty-two, and Jenkins, to that of one hundred and sixty-nine, as recorded in the Philosophical Transactions ; we have many instances of the prolong- ation of life to one hundred and ten, and even to one hundred and twenty years. Yet this longevity was owing to no peculiar art or management. On the con- trary, it appears, that the greater number of such long livers were peasants accustomed to the greatest fatigues, huntsmen, or labourers ; men, in fact, who had em- ployed their whole bodily strength, and even abused it, if it be possible to abuse it by any thing but by con- tinual idleness and debauchery. If in the duration of life there is any difference to be found, it seems proper to ascribe it to the quality of the air. In elevated situations, old people are more generally found than in low ones. In the mountains of Scotland and Wales, Auvergne and Switzerland, there have been more instances of extreme longevity than in the plains of Holland or Flanders, of Germany or Poland. Hu- man life is however nearly the same in every country. Accidental distress excepted, the common verge of ex- istence is ninety or an hundred years, which has been the case since the days of David, without much vari- ation.

The organs by which the senses act are the nerves, which are small thread-like fibres distributed over the whole bodyj and all of them connected with the brain. The eyes seem to be formed very early in the human embryo. In the chicken also, of all the parts that are double, they are the soonest produced ; and I have ob- served upon the eggs of several sorts of birds, as well as upon those of lizards, that the eyes were much larger and earlier in their expansion, than any other parts of two-fold growth. Though in viviparous ani- mals, and particularly in man, they are, at first, by no means so large in proportion as in the oviparous classes, yet they obtain their due formation sooner than any other parts of the body. This is also the case with the organ of hearing. The little bones that assist in constructing the internal parts of the ear are entirely formed before any of the other bones have acquired any part of their growth or solidity. Hence it is evident, that the parts of the body which are furnished with the greatest quantity of nerves are those which appear first, and which first attain to perfection. Mr Chesselden having couched, for a cataract, a lad of thirteen years of age, who had from his birth been blind, and thus communicated to him the sense of seeing, was at great pains to mark the progress of ' his visual powers. This youth, though hitherto inca- pable of seeing, was not, however, absolutely and en- tirely blind. Like every other person, whose vision is obstructed by a cataract, he could distinguish day from night, and even black from wliite, or either from the vivid colour of "scarlet. Of the form of bodies, NATURAL HISTORY. 9; however, he could distinguish nothing, nor of colours themselves, unless the light was strong. At first the operation was performed only upon one of his eyes ; and when he saw for the first time, he was so far from forming the least conception of distances, that he supposed (as he himself expressed it) every thing lie saw touched his eyes, in the same manner as every- thing he felt touched his skin. The objects that pleased him most were those of which the surfaces were plain, and the figures regular ; though he could neither judge of their different forms, nor give any reason why he preferred some to others. The ideas lie had entertained of colours, during his former dark state, were so imperfect, that, when he saw them in reality, he could hardly he persuaded they were the same. When such objects were shewn him as he had been formerly familiar with, by the touch, he beheld them with earnestness, in order to distinguish them a second time. As of these, however, he had too many to retain at once, the greatest number were forgot ; and for one thing which he recollected upon seeing a second time, there were a thousand of which he had not the least remembrance. He was very much sur- prised to find that those persons, and those objects, which he had loved best, were not the most pleasing to the eye. Nor could he help expressing his disap- pointment in finding his parents less handsome than he had conceived them to be. Before he ccnld dis- tinguish that a picture resembled a solid body, above two months elapsed. Till then, he only considered it as a surface diversified by a variety of colours ; but, when he began to perceive that these shadings actually represented human beings, he also began to examine, by the touch, whether they had not the usual qualities Vol. I. M .98 NATURAL HISTORY. of such bodies ; and great was his surprise to firrd what he had imagined a very unequal surface, to be smooth and even. He was then shewn a minature portrait of his father, which was contained in his mo- ther's watch-case ; and though lie readily perceived the resemblance, yet he expressed his astonishment, how so large a face could be comprised in so small a com- pass. To him it appeared as strange as that a pint vessel should contain a bush-jl. At first, he could bear but a very small quantity .of light, and he saw every object much greater than the life. But in pro- portion as he observed objects that were really large, he conceived the others to be diminished. Beyond the li- mits of what he saw, he had no conception of any thing. Although he knew that the apartment he oc- cupied was only a part of the house, he could not con- ceive how the latter should seem larger than tiie for- mer. Before the operation he had no great expectation of the pleasure he should receive from the new sense be was promised. That by it he might be enabled to read and write, was his grand object. He said, that he could enjoy no greater satisfaction from walking in the garden, with this sense, than without it ; because there he already walked at his ease, and knew all the walks. With great truth he also observed, that his blindness gave him one advantage over the rest of man- kind ; an advantage which indeed he retained long af- ter he had acquired the sense of seeing ; namely, that of being able to walk in the dark with confidence and security. He no sooner, however, had begun to enjoy this new sense, than he was transported beyond mea- sure ; and he declared that every new object opened to him a fresh source of delight. About a year after, he was carried to Epsom, where there is a beautiful, NATURAL HISTORY. 99 and an extensive prospect. With this he seemed great- ly charmed ; and the landscape before him he called a new method of seeing. He was couched in the other eye, a year after, and of hoth operations the success was equal. AVhen he saw with both eyes every thing appeared to him twice as big as when he saw but with one, although he did not see double, or at least he dis- covered no marks from which any such conclusion could be inferred. Distance is only conceived by experience, for the tr.ore distant an object is, the less it appears. When, from certain circumstances, we cannot form a just con- ception of distance, and when we cannot judge of ob- jects but by the angle, or rather by the image, which they have in our eyes, we are then necessarily deceived as to their size. Every man has felt, how liable we are in travelling by night to mistake a bush which is near for a tree at a distance, or indeed a distant tree for a bush at hand. In the same manner if we do not dis- tinguish objects by their shape, and if we cannot by it judge of distance, the same fallacy will still continue. Jn this case, a fly, which may pass before us with rapidity, will seem to be a bird at a considerable dis- tance; and a horse which may be in the middle of a plain, not moving, and in an attitude similar, for in- stance, to that of a sheep, will seem to be no bigger than a sheep, till we have found out that it is a horse. If, therefore, we are benighted in a strange place, where no judgment can be formed of distance, we are every moment liable to deceptions of vision. Hence originate the dreadful stories of spectres, and of those wonderful, hideous, and gigantic figures, which so many persons speak of having seen. Though such figures, it is commonly asserted, exist solely in the iaui- 100 NATURAL HISTORY. gination, yet it is highly probable that they might ap- pear to the eye, in every different respect described to us. This remark will be allowed to be more probable, when we consider, that whenever we cannot .judge of an object but by the angle which it forms in the eye, this object is magnified according to its propinquity. And that, if it seemed at first to the spectator, who is equally incapable of distinguishing what he sees, and of judging at v;hat distance he sees it, when at the dis- tance of twenty or thirty paces from it, a few feet high, it must look to him, when within a jew feet of it, of a size stupendously increased. At this he must natur- ally be terrified, till he touches and distinguishes the seemingly gigantic object, for, in the very instant that he has an actual perception of what it is, the object will diminish, and appear to him what it really is. If, on the other hand, he is afraid to approach it, and he flies from the spot with precipitation, the only idea he will form of what had presented itself to him, will be that of an image, gigantic in its size, and dreadful in its form. This prejudice about spectres, therefore, originates from nature ; and such visions depend not, as philosophers have supposed, upon the imaginatiou only. We have several reasons for supposing that such persons as are short-sighted see objects larger than others ; and yet it is a certain fact that they see them less. Deception is not, however, confined to one sense ; so that hearing is liable to similar mistakes with sight. By this sense no distinct intelligence is conveyed of the distance whence a sounding body is heard. A great noise, if distant, and a small one, very near, produce the same feeling ; and unless we receive information NATURAL HISTORY. 101 from some other sense, we can never tell accurately whether the sound be great or small. It is not till we have by experience become acquainted with any particular sound, that we can judge of the distance whence we hear it. When, for example, Ave know the tone of a bell, we are then at no great loss to determine how far it is from us. Every body that strikes against another produces a sound, which is simple in such bodies as are not elastic, but which is often repeated in such as are. If we strike a bell, for instance, a single blow produces a sound, which is repeated by the undulations of the sonorous body, and which is multiplied as often as it happens to undulate or vibrate. These undulations succeed each other so fast, that the ear supposes them one continued sound ; whereas they form many sounds. Sounding bodies are therefore of two kinds, to wit, non-elastic and elastic. The former when struck return but a single sound, and the latter return a succession of sounds, which form a tone. This tone may be con- sidered as a great number of sounds, all produced one after the other, by the same body, as we find in a bell which continues to sound for some time after it is struck. A continuing tone may also be produced from a non- elastic body, by repeating the blow quick and often, as when we beat a drum, or when we draw a bow along the string of a fiddle. To know the manner in which musical sounds be- come pleasing, it must be observed, no one continu- ing tone3 how loud or swelling soever, can afford us delight. We must have a succession of them, and those in the most pleasing proportion. The nature of this proportion may be thus conceived. If we strike a body incapable of vibration with a double 102 NATURAL HISTORY. force, or, what amounts to the same thing, with a double mass of matter, it will produce a sound that will be double grave. Music has been said, by the ancients, to have been first invented from the blows of different hammers on an anvil. Suppose then we strike an anvil with a hammer of one pound weight, and again with a hammer of two pounds, it is plain that the two pound hammer will produce a sound twice as grave as the former. But if we strike with a two pound hammer, and then with a three pound, it is evident that the latter will produce a sound one third more grave than the former. If we strike the anvil with a three pound hammer, and then with a four pound, it will likewise follow that the latter will be a quar- ter part more grave than the former. Now, in com- paring between all those sounds, it is obvious that the difference between one and two is more easily perceived than that between two and three, three and four, or any number succeeding in the same propor- tion. The succession of sounds will therefore please in proportion to the ease with which they may be distinguished. That sound which is double the for- mer, or, the octave to the preceding tone, will be the most pleasing. The next to that, which is as two or three, or, the third, will be most agreeable. And thus universally, those sounds whose differences may be most easily compared are the most agreeable. Sound has in common with light, the property of being extensively diffused. Like light, it also admits reflection. The laws of this reflection, it is true, are less distinctly understood than those of light. All we know is, that sound is principally reflected by hard bodies, and that their being hollow also some- times increases the reverberation, The internal cavity NATURAL HISTORY. i03 «f the ear, which is fashioned out in the temporal bone, like a cavern cut into a rock, seems to be fitted for the purposes of echoing sound with the greatest precision. One of the most common complaints in o!d age ia deafness; which probably proceeds from the rigidity of the nerves in the labyrinth of the ear. This disorder also proceeds sometimes from a stoppage of the wax, which art may easily remedy. In order to know whe- ther the defect be an internal or an external one, let the deaf person put a repeating-watch into his mouth ; and if he hears it strike, he may be assured that hi* disorder proceeds from an external cause. It often happens, that people hear better with the one ear than with the other ; but these have, what musicians call, a bad ear. I have made several expe- riments on persons of this description ; and I have uniformly found, that their defect in judging properly of sounds proceeds from the inequality of their ears, and from their receiving by both at the same time, unequal sensations. In like manner, as such persons hear false, they also, without knowing it, sing false. They also frequently deceive themselves with regard to the side whence the sound comes, generally sup- posing the noise to come on the part of the best ear. Hearing is a much more necessary sense to man than to animals. In these it is only a warning against danger, or an encouragement to mutual assistance. In man, it is the source of most of his pleasures ; and without it the rest of his senses would be of little benefit. A man born deaf, must necessarily be dumb ; and his whole sphere of knowledge must be bounded by sen- sual objects. We have a singular instance of a young man, who, being born deaf, was restored, at the age 104 NATURAL HISTORY. of twenty-four,, to perfect hearing. The account which is given in the memoirs of the Academy of Sciences, 1703, page 18, is as follows : " A young man, of the town of Ciiartres, between the age of twenty-three and twenty-four, the son of a tradesman, and deaf and dumb from his birth, began to speak all of a sudden, to the utter astonishment of the whole town. He gave them to understand that, about three or four months before, he had heard the sound of the bells, and was greatly surprised at this new and unknown sensation. After some time, a kind of humour issued from his left ear, and he then heard perfectly well with both. During these three months he listened to every thing ; and without attempting to gpeak aloud he accustomed himself to utter softly the •words spoken by others. He laboured hard also in acquiring the pronunciation of words, and in learning the ideas of which they are expressive. At length, having supposed himself qualified to break silence, he declared, that he could now speak, though as yet but imperfectly. Soon after, some able divine questioned him concerning his ideas of his past state ; and prin- cipally with respect to God, his soul, the moral beauty of virtue, and deformity of vice. The young man, however, had not directed his solitary speculations in- to that channel. He had gone to mass indeed w ith his parents, had learned to sign himself with the cross to kneel down, and to assume all the grimaces of a man in the act of devotion. But he did all this with- out any manner of knowledge of the intention or the cause ; he saw others do the like, and that was e- nough for him. He had formed no idea of deatli ; but he led a life of pure animal instinct ; and though entirely taken up with sensible objects, and such a* NATURAL HISTORY. 105 were present, he yet did not seem to have mane such reflections even upon these, as might reasonably have been expected. The young man was not, however, deficient in understanding ; but the understanding of a man, deprived of all commerce with others, is so very confined, that the mind may be said to be under the control of its immediate sen sations. " It is highly possible, nevertheless, to communicate ideas to deaf men, which they previously wanted, and even to give them very precise notions of abstract and general subjects, by means of signs and of Jetters. A person born deaf may, by time and application, be taught to read, to write, and even by the motions of the lips to understand what is said to him. This is a plain proof how much the senses resemble, and may supply the defects of each other. It is probable, how- ever, that as most of the motions of speech are made within the mouth by the tongue, the knowledge from the motion of the lips can be but very confined. The sense of feeling is spread over the whole bo'dy, but it employs itself differently in different parts. The sensation which results from feeling, cannot be excited otherwise than by the' contact and immediate application of the superfices of some foreign body to that of our own. If we apply a foreign body against the. breast, or upon the shoulder of a man, he will feel it ; that is, he will know that there is a foreign body which touches him. But he will not have a single idea of the form of this body, because the breast touch- ing the body in a single plain, or surface, he cannot gather from it any knowledge of this body. It is the same with respect to all other parts of the body, which cannot adjust themselves upon the surface of foreign bodies, and bend themselves, to embrace at one time- 'Vol. I. N 100 NATURAL HISTORY. many parts of their superfices. These parts cf ouv. body cannot, therefore, give any just idea of their form; but .those on the contrary, which, like the Rand, art- divided into small flexible and moveable parts, and which, consequently, can apply themselves at one and tile same time, upon the different plains of the super- flees of the bod}', are those, wliieh, Li e.ftect, give us the ideas of their form, ar.d of iheir size. It is not, therefore, only because there is a greater quantity of nervous tufts at the extremity of the fin- gers than in any other part of the body. It is not, a* it is vulgarly pretended, because the hand lias the most delicate sense, that it is in effect the principal organ of feeling. On the contrary, we can say that there are parts more sensible, and where the sense of feeling is more delicate, as the eyes, the tongue, &c. But it is merely because the hand is divided into ma- ny parts, all moveable, all flexible, alt acting at the same time, and all obedient to the will ; it is, because it is the only organ which gives us distinct ideas of the form of bodies. Animals which have hands, ap- pear to be the -most acute. Apes do things so like the mechanical actions of man, that it seems as if they had the same succession of corporeal sensation for the cause of them. Animals, which are deprived of this organ, as they cannot grasp any object, and as they have not any part divided and flexible enough to be able to adjust itself upon the superfices of bodies, they certainly have not any precise notion of the form, or of the size of them. It is for this reason that we of- ten see them in suspense, or frightened at the aspect of objects which are the most familiar to them. The principal organ of their feeling is the muzzle, as this part is divided in two by the mouth, and as the tongue NATURAL HISTORY. 107 Is another part, that serves them at the same time to touch bodies, which we see them turn and turn again before tfiey take them between their teeth. It is therefore to the sense of feeling that we are indebted for the power of usefully exercising all other faculties. One "inn does not, perhaps, possess more ingenuity or capacity than another; but because in "his earliest infancy he made a greater, and a readier use of this sense. As soon as children are indulged with the liberty of their hands they presently bring them into action, and are fond of touching whatever is presented to them. They are seen to amuse them- selves, and to take a pleasure in handling every thing they are capable of grasping. They seem as if they were endeavouring to find out the form of bodies, by touching them on every side ; and for a considerable time, they amuse themselves in this manner, or rather they inform themselves of new objects.

J. HERE are many causes which contribute to pro- duce an apparent variety between the different na- tions of the globe. Climate, food, manners and cus- toms, produce not only a difference in sentiment, but oven in the external form of differer.t people. 108 NATURAL HISTORY In examining the surface of the earth, and beginning our inquiries from the north, we find in Lapland, and in the northern parts of Tartary, a race of small-sized men, whose figure is uncouth, and whose physiognomy is as wild as their manners are unpolished. Though they seem to be of a degenerate species, they are very nu- merous, and occupy vast regions. The Laplanders, the Danes, the Swedes, the Mus- covites, the inhabitants of Nova Zembla. the Boran- dians, the Samoeids, the Ostiacs of the old continent, the Greenlanclers, and the savages to the north of the Esquimaux Indians of the new continent, appear to 1)0 of one common race, which has been extended and mul- tiplied along the coasts of the northern seas, and over deserts, considered as uninhabitable by every other na- tion. In these countries, the visage is large and broad,* the nose is flat and short, the eyes are of a yellowish brown, inclining to black, the eye-lids are drawn towards the temples, the cheek-bones are extremely prominent, the mouth is very big, the lower part of the countenance is very narrow, the lips are thick and turned out- ward, the voice is shrill, the head is bulky. The hair is black and straight, and the skin is tawny. They are small in stature, and, though meagre, they are of a squat form. In general, their size is about four feet, nor do the tallest exceed four and a half; and among these people, if there is any difference to be found, it depends on the greater or less degree of deformity. The Danish Laplanders have a large black cat, which they make a confidant of all their secrets, and a coun- sellor in all their difficulties. Among the Swedish Lap- landers, there is in every family a drum, for the pur- pose of consulting the devil : and notwithstanding the .natives of these countries are robust and nimble^ from NATURAL HISTORY. 109 many circumstances there is reason to suppose, that they cannot live but in their own country, and in their own manner. In travelling over the ice and snow, they use skates made of fir, which are about two feet long, and about half afoot broad, which are raised and point- ed before, and fastened to the foot by straps of leather. With these they make such dispatch, that they easily overtake the swiftest animals. They also use a pole, pointed with iron at one end, and rounded at the other. This pole serves to push them along, to direct their course, to keep them from falling, to stop the impetuosity of their career, and to kill what game they overtake. With their skates they descend the steepest mountains, and scale the most craggy precipices ; nor are the wo- men less skilful in such exercises than the men. They are all accustomed to the bow and arrow ; and it is as- serted, that the Muscovite Laplanders lance a javelin with so much dexterity, that at the distance of thirty paces, they are sure to hit a mark no larger than a silver crown, and with such force, that it will transfix a human body. As huntsmen, their favourite pursuit is that of the ermine, the fox, the lynx, taid the martin ; and of these animals, they barter the skins for their fa- vourite articles of luxury, brandy and tobacco. In winter, the Laplanders clothe themselves with the skin of the rein-deer, and in summer with the skins of birds. To the use of linen they are perfect strangers. The women of Nova-Zembla have their nose and their ears pierced, in order to have them or- namented with pendants of blue stone ; and also, as an additional lustre to their charms, they form blue- streaks upon their forehead and chin. Those of Green- land dress themselves with the skin of the dog-fislu They also paint the visage with blue and yellow cq- 110 NATURAL HISTORY. lours, and wear pendants at their ears. They all live under ground, or in huts almost entirely covered with earth, and with the bark of certain trees, or the skin . of certain fishes. Some even form subterranean trench- es, by which one hut communicates with another, and by which, during the winter months, they enjoy the conversation and society of their neighbours. A con- tinued series of darkness for several months, obliges them to illuminate their dreary abodes with lamps, which they keep alive with that very train-oil they use as drink. Under all these hardships, they are subject to few diseases, and they live to a prodigious age. So vigorous indeed are the old men, that they are hardly to be distinguished from the young. The only infirmity they experience, and it is an infirmity common to them all, is blindness. Dazzled by the strong reflection of the snow, in winter, and enveloped in clouds of smoke in autumn and spring, when advanced in years, they seldom retain the use of their eyes. The Tartar country, taken in general, comprehends the greatest part of Asia, and extends even from Rus- sia to Karntschatka. It is from eleven to twelve hun- dred leagues long, and about seven hundred broad, nf course its circumference is twenty times larger than that of the whole kingdom of France. All the Tartar nations have the upper part of the visage very large and wrinkled, even in their youth. Their nose is short and flat, their eyes are little and sunk in the head ; their cheek bones are high ; the lower part of their visage is narrow ; their chin is Ion;; and prominent-; their teeth are long and straggling ; their eye-brows are so large as to cover the eyes ; llmir eye-lids arc thick ; the face is broad and flat ; NATURAL .HISTORY. Ill tiieir complexion is tawny, and their hair is black. They have hut little heard, have thick thighs, and .short legs, ajid, though but of middling stature, they arc remarkably strong and robust. The ugliest of them are the Calmouks, in whose appearance there seems to be something frightful. They are all wan- derers and vagabonds ; and their only shelter is that of a tent made of hair or skins. Their food is horse- flesh and camel-flesh, either raw, or a little soJden between the horse and the saddle. They eat also fish dried in the sun. Their most common drink is mare's milk, fermented with millet ground into meal. Thsy all have the head shaved, except a tuft of hair on the top, which they let grow sufficiently long to form in- to tresses on each side oF the face. The women who are as deformed as the men, wear their hair, which they bind up with bits of copper, and other ornaments of the same nature. The majority of these tribes are strangers to religion, morality, and decency. They are robbers by profes- sion ; and the natives of Daghestan, who live in the neighbourhood of more polished countries, carry on a great traffic of slaves, whom they carry off by force, - and afterwards sell to the Turks and the Persian;. Their wealth consists chiefly of horses, which are more numerous', perhaps, in Tartary, than in any other part of the world. They are taught, by custom, to live in the same place with their horses. They are continu- ally employed in training and exercising them ; and at length they reduce them to such implicit obedience, that they actually appear to understand the intention of the rider. The limbs of the Chinese are well-proportioned, their bodies are large and fat, their visages are large 112 NATURAL HISTORY. and round. Their eyes are small, their eye-brows are large, their eye-lids are turned upwards, and their noses are short and flat. Their beards are black, upon their chins there is very little hair, and upon each lip there- are not more than seven or eight prickles. Those who inhabit the southern provinces of the empire, are more brown and tawny than the others. In colour, they resemble the natives of Mauritania, and the more swar- thy Spaniards ; but those who inhabit the middle pro- vinces are as fair as the Germans. Le Gentel assures us, that the Chinese women do every thing in their power to make their eyes appear little, and oblong. For this purpose, it is a constant practice with the little girls, from the instruction of the mother, forcibly to extend their eye-lids ; and with the addition of a nese thoroughly compressed and flattened, of ears long, large, open, and pendant, they are accounted complete beauties. He adds, that their complexion is delicate, there lips are of a fine vermi- lion, their mouth is well-proportioned, their hair is very black ; but that, by the use of paint, tliey so greatly injure their skin, that, before the age of thirl v, they have every appearance of old age. So strongly do the Japanese resemble the Chinese, that we can hardly scruple to rank them in the same class. As being inhabitants of a more southern cli- mate, they only differ from them in being more yellow or more brown. In general, their stature is small, their face, as well as their nose, is broad and flat, their hair is black, and their beard is little more than per- ceptible. They are haughty, fond of war, full of dex- terity and vigour, civil and obliging, smooth-tongued, and courteous, but fickle and vain. With astonishing patience, they sustain hunger, thirst, cold, heat, fa-- NATURAL HISTORY. n., iigue, and all the other hardships of life. Their ce- remonies, or rather grimaces, in eating, are numerous and uncouth. They are laborious, are very skilful artificers, and, in a word, have nearly the same dispo- sition, the same manners, and the same customs, as the Chinese. One custom which they have in common, and which is not a little fantastic, is, so to contract the feet of the women, that they arc hardly able to support them- selves. Some travellers mention, that in China, when a girl has passed her third year, they break the foot in such a manner, that the toes are made to come un- der the sole ; that they spply to it a strong water, which burns away the flesh ; and that they wrap it up in a number of bandages, till it has assumed a cer- tain fold. They add, that the women feel the pain of this operation all their lives ; that they walk with great difficulty ; and that their gait is to the last de- gree ungracefjl. Other travellers do not say that they break the foot in their infancy, but they only- compress it with so much violence as to prevent its growth ; but they unanimously allow, that every woman of condition, and even every handsome woman must have a foot small enough to enter, with ease, the slipper of a child of six years old. Though the inhabitants of the kingdoms of Pegu and Aracan are blacker, yet they bear all a consider- able resemblance to the Chinese. Those of Aracan put great value upon a forehead large and flat ; and, in order to render it so, they apply a plate of lead to the forehead of their children as soon as they are born. Their nostrils are large and extended ; their eyes ant small and lively ; and their ears are of such length as to hang over their shoulders. They feast with a VoCl. Q ill. NATURAL HISTORY. relish on mice1, on 'rats, on serpents, and on fish, how- ever it may stink. Their women are tolerably fair, and their ears are as long as those of the men. The people of Achan, who are situated farther to the north than those of Aracan, have also a flat visage, and an olive-coloured skin. They allow their boys to go quite naked, and their girls with only a slight plate of silver over those parts which nature dictates to conceal. Northward of the Phillippine Islands is situated the island Formosa, of which the natives, though at no great distance from the coast of Fokian in China, bear not the least resemblance to the Chinese. Ac- cording to Struys, the Formosans are of a small sta- ture, particularly those who inhabit the mountains, and their visage is broad. The women have large and full breasts, and a beard like the men. Their ears are naturally long, and they render them still more so by certain thick shells, which they wear as pendants. Their hair is very black, and very long, and their com- plexion is yellowish. These Islanders, though averse to labour, are yet admirably skilled in the use of the javelin and bow. They are also excellent swimmers ; and when they run, their swiftness is incredible. The Moguls, and the other inhabitants of the penin- sula of India, are not unlike the Europeans in shape and in features ; but they differ more or less from them in colour. The Moguls are of an olive complex- ion ; and yet, in the Indian language, the word Mogul signifies White. The women areextremely delicate, and they bathe very often. They are of an olive colour, as well as the meii ; and, contrary to what is seen a- mong the women of Europe, their legs and thighs are long, and their body is short. Tavernier says, that, NATURAL HISTORY. 11.3 after passing Lapor, arid the kingdom of Cashmire, the women have no hair on any part of the body, and ihe men have hardly any beard. According to Theve- not, the Mogul women are tolerably fruitful, though ex- ceedingl y chaste. They likewise suiter little from the pains of child-birth, and are often known to be abroad the day following. He adds, that in the kingdom of Decan they are allowed to marry, the husband by his tenth, and the wife by her eighth year ; and at that age they very often have children. The women who become mothers so soon, usually cease bearing, how- ever, before they arrive at thirty ; and by that period, they appear wrinkled^ and marked with all the defor- mities of age. The customs of the different nations of India are all very singular, if not whimsical. The Banians eat nothing which has life in it; and they are even afraid to kiii the smallest reptile, however offensive to them. They throw rice and beans into their rivers as food for the fishes, arid grain of different kinds upon the c-arih for the birds and insects. When they meet with a huntsman, or a fisher, they beg of him instantly to desist from his employment. If he remain deaf to their in- treaties, they offer him money for his gun, or his nets ; and when no persuasion, no offer, will avail, they trouble the water, in order to frighten the fishes, and cry with all their might, to put the birds and other game to flight. In Ceylon there is a species of savages, denominated Bedas, who occupy a small district on the north part of the island, and seem to be totally different from all the nations around them. The spot they inhabit is en- tirely covered with wood, amidst which they keep themselves so closely concealed, that it is with greai i\6 NATURAL HISTORY: difficulty they are discovered. Their complexion 19 fair, and sometimes even red, like that of the Europeans. They do not speak the language of Ceylon ; nor indeed has their language the least affinity to that of any of the other Indians. They have no villages, no houses, no intercourse with the rest of mankind. Their arms are, the bow and the arrow, with which they destroy a number of boars, stags, and other animals ; and though they never dress their meat, they sweeten it with honey, winch they possess in great abundance. The inhabitants of Persia, of Turkey, of Arabia, of Egypt and of the whole of Barbary, may be consider- ed as one and the same people, who, in the time of Mahomet, and of his 'successors, invaded immense ter- ritories, extended their dominions, and incorporated with the original natives of all those countries. The Persians, the Turks, and the Moors, arc to a certain degree civilized ; but the Arabians have, for the most part, remained in a state of independence, which im- plies a contempt of laws. They live, like the Tartars, without order, without government, and almost with- out society. Theft, robbery, and violence, are author- ized by their chiefs. They glory in their vices ; and of all human conventions, those only have they ad- mitted which owe their existence to fanaticism and superstition. They are a people much inured to labour ; and to it they habituate their horses. They allow this ani- mal to eat and drink but once in twenty-four hours ; and though their horses are meagre, they are excellent coursers, and seem indefatigable. The Egyptian women are very brown ; their eyes nre lively ; their stature is rather Jow ; their mode of is by no means agreeable ; and their conversation NATURAL HISTORY. 117 is pcfectly tiresome. But though the women of Egypt are commonly rather short, yet the men are of a good height. Both are of an olive colour; and the farther we remove from Cairo, the more we find the people tawny, till we reach the confines of Nuhia, where they are as black as the Nubians themselves. The most inherent defects of the Egyptians are idle- ness and cowardice. They do nothing almost the whole day but drink coffee, smoke, sleep, remain in- dolent in one place, or chatter in the streets. They are highly ignorant, and are full of the most ridiculous vanity. Though they cannot deny but that they have lost every thing noble they once possessed ; the scien- ces, the exercise of arms, their history, and even their language ; and that, from an illustrious and a valiant nation, they have become a people dastardly and ensla- ved ; they scruple not to despise all other nations, and to take offence at the bare offer of carrying their chil- dren into Europe, in order to initiate them in the arts and sciences. " The women of Circassia," says Struys, " are ex- ceedingly fair and beautiful. Their complexion is in- comparably fine ; their forehead is large and smooth ; and, without the assistance of art, their eye-brows are so delicate, that they appear as threads of silk. Their eyes are large, soft, and full of animation, their mouth is small and expressive of a smile, and their chin forms a perfect oval. Their neck and breasts are admirably formed ; their stature is tall, and the shape of their body easy ; their skin, is white as snow, and their hair of the most beautiful black. They wear a little cap of a black stuff, over which they fasten a roller of* the same colour ; but, what is truly ridiculous, is, that, instead of this roller, the widows wear the blad- 118 NATURAL HISTORY. der of an ox, or a cow, inflated as much as possible, by which they disfigure themselves amazingly. In the summer months the inferior classes wear nothing but a shift, which is open down to the middle, and which is generally of a blue, yellow, or red colour. They are tolerably familiar with strangers, but at the same tin-.e faithful to their husbands, who are by no means jealous; of them." The Turks, who purchase a vast number of these women as slaves, arc a people composed of many dif- ferent nations. From the Armenians, the Georgians, the Turcomans, intermixing in the time of the crusades with the Arabians, the Egyptians, and even the Eu- ropeans, it is hardly possible to distinguish the native inhabitants of Asia Minor, of Syria, and of the rest of Turkey. The Turkish men are generally robust, and tolerably well-made ; and it is even rare to find among them persons either hump-backed or lame. The women are generally beautiful, well-proportioned and free from blemishes. They are very fair, because they seldom stir from home ; and when they go abroad they are always veiled. Before the Czar Peter I. we are told, that the Mus- covites had not emerged from barbarism. Born in slavery, they were ignorant, brutal, cruel, and des- titute of courage. Men and women bathed promiscu- ously in stoves heated to a degree intolerable to all persons but themselves; and on quitting this warm Lath, they plunged, like the Laplanders, into cold water. Their food was homely ; and their favourite dishes were cucumbers, or melons, of Astracan, which, in summer, they preserved in a mixture of water, flour, and salt. From ridiculous scruples they ab- stained iiora several viands, amongst which were NATURAL HISTORY. llj) pigeons anil veal. Nevertheless, at this period of rudeness, the women were" skilful in the arts of co- louring the skin, of plucking out the eye-brows, and of painting artificial ones. They also adorned them- selves with pearls and jewels, and their garments were made of rich and valuable stuffs. From these circumstance? does it not appear, that the barba- rism of the Muscovites was near a close, and that their sovereign had less trouble in polishing them than some authors have endeavoured to insinuate? They are now a people in some degree civilized and com- mercial, fond of spectacles, and of other ingenious novelties. From the regions of Europe and Asia, our attention is now to be directed to a race of people differing more from ourselves in external appearances than any we have hitherto mentioned. In the seventeenth or eighteenth degree of north latitude, on the African coast, we find the negroes of Senegal and of Nubia, some in the neighbourhood of the ocean, and others in that of the red sea. After them, all the nations of Africa, from the latitude of eighteen North to that of eighteen South, are black; the Ethiopians, or Abyssinians, excepted. It appears, then, that the portion of the globe which Nature has allotted to this race of men, contains an extent of ground, parallel to the equator, of about nine hundred leagues in breadth, and considerably more in length, especially northward of the equator. Beyond the latitude of eighteen or twenty, there are no more ne- groes, as will appear when we come to speak of the Caffres, and of the Hottentots. By confounding them with their neighbours the Nubians, we have been long in a« error, with respect 120 NATURAL HISTORY. to the colour, and the features of the visage of the Ethiopians. Marmot says, that the Ethiopians are absolutely black, that their visage is large, and their nose flat ; and in this description the Dutch travellers agree with him. The truth, however, is, that they differ from the Nubians, both in colour and in features. The skin of the Ethiopians is brown, or olive-coloured, like that of the southern Arabians, from whom, it is probable, they derive their origin. In stature thev are tall : the features of their countenance arc strong- ly marked : their eyes are large and beautiful : their nose is well-proportioned : their lips are thin ; and their teeth are white. Of the inhabitants of Nubia, on the contrary, the nose is flat, the lips are thick ami prominent, and the countenance is exceeding black. These Nubians, as well as the Barberins, their western neighbours, are a species of Negroes not unlike those of Senegal. The Ethiopians are a people between the extremes of barbarism and of civilization. Their garments are of cotton, though those of the more opulent are of silk. Their houses are low, and of a bad construction. Their lands, too, are wretchedly neglected. These circumstances are owing to the behaviour of their no- bles, who despise the tradesmen and the common peo- ple. Each of these classes, however, lives separate from the other, and has its own villages or hamlets. Unprovided with salt at home, they purchase it from abroad for its weight in gold. So fond are they of raw meat, that, at their feasts, the second course, which is considered as the most delicate, consists of it entirely. Though they have vines they have no wine ; and their usual beverage is a sour composition- Made with tamarinds. They use horses for the pur- NATURAL HISTORY. 121 pose of travelling, and mules for that of carrying their merchandise. Of the arts or sciences they have lit- tle knowledge. Their language is without rules ; and their manner of writing, though their characters are more beautiful than those of the Arabians, is so im- perfect, that they take seveial days to write a letter. In their mode of salutation there is something exceed- ingly whimsical. Each takes the right hand of the other, and carries it to his mouth ; after, the saluter takes off the scarf of the person saluted, and fastens it round his own body : Thus the latter is left half naked, few of the Ethiopians wearing any more than this scarf, and a pair of cotton drawers. The first Negroes we meet with are those who live on the south side of Senegal. These people, as well as those who occupy the different territories between Senegal and Gambia, are called Jalofes. They are all very black, well-proportioned, and of a size suffi- ciently tall. Their features are less harsh than those of the Negroes ; and some of them, especially of the female sex, have features that are far from being irregular. With respect to beauty, they value fine eyes, a well made nose and mouth, and lips of a proportional smallness. With respect to the ground of the picture alone do they differ from us ; for, with them, the colour must be exceedingly black and glos- sy. Their skin, however, is highly delicate, and soft ; and, colour excepted, we find among them women as handsome as in any other country of the world. They are usually very gay, lively, and amorous. Father du Tertre says expressly, that if the Negroes are for the most part flat-nosed, it is because the pa- rents crush the noses of their children. He adds, that they compress their lips too, in order to render them Vol. I.

Though the Negroes of Guinea are in general very healthy, yet they seldom attain what we term old age. In his own country, a Negrore at the age of fifty, is a very old man ; and so early as that of forty, he dis- covers all the marks of being so. The Negroes in general are remarkably innocent and inoffensive. If properly fed, and not exposed to bad usage, they are contented, joyous, and obliging ; and on their very countenance we may read the satis- faction of their soul. If hardly dealt with, on the other hand, their spirits forsake them, and they droop with sorrow. Alike impressed with a sense of what injuries, and of what favours they have received, to a cruel master they are implacable foes. But to an indulgent one, they are servants who will exert every effort of which human na- ture is capable, in order to express to him their zeal and attachment. To their children, their friends, their countrymen, they are naturally compassionate and ten- der. Contented with the little they have, they com- municate a share to whose who are in indigence, That they have an excellent heart, therefore, is evident; and, in having this, they have the seed of every virtue. Their sufferings demand a tear. Are they not already NATURAL HISTORY. sufficiently unhappy in being reduced to a state o£ slavery; in being obliged to work without reaping the smallest fruits of their labour ? To cro\v;i their wretch- edness, must they be abused, buflV'led, treated like brutes?

Mr Kolbe, though he has given so minute a descrip- tion of the Hottentots, is strongly of opinion, however, that they are negroes. Like that of the latter, he as- sures us, their hair is short, black, frizzled, and woolly; nor in a single instance did he ever observe it long. Though of all the Hottentots the nose is very flat, and very broad, yet it would not be of that form, did not their mothers, considering a prominent nose as a deformity, crush it presently after their birth. Their lips are also thick, and their upper lip is particularly so: their teeth are very white; their eye-brows are thick ; their head is large ; their body is meagre ; and their limbs are slender. They seldom live above forty years ; and of this short duration of life, the causes, no doubt, are, their residing continually in the midst of filth, as also their living upon meat that is tainted, of which indeed their nourishment chiefly consists. I might dwell longer upon the description of this nasty people ; but as most travellers have already given very accurate accounts of them, it might be thought unnecessary in this place. One fact, however, related by Tavernier, I ought not to pass in silence. The Dutch, he says, once took a Hottentot girl, soon after bc-r birth ; and, after bringing her up amoJig them- •424 NATURAL HISTORY. selves, she became as white as an European. From this circumstance lie presumes, that all the Hottentots •would be tolerably white, were it not for their custom of perpetually begriming themselves. Though in America we observe less variety in the human form than might be expected, it cannot be sup- posed, but that in such a diversity of climates and situations, a considerable diversity of inhabitants must also be found. In beginning our inquiries, then, we find in the most northern parts of America a species of Laplanders, similar to those of Europe, or to the Samoeids of Asia ; and though, in comparison of the latter, they are few in number, yet they are diffused over a very consider- able extent of ground. Those who inhabit the lands of Davis's Straits, are of a diminutive size, of an olive complexion, and their legs are short and thick. They are skilful fishers. They eat their fish and their meat raw. Their drink consists of pure water, or of the blood of the dog-fish. They are also very strong, and generally live to a great age. Here, we see, there- fore, the figure, the colour, and the manners of the Laplanders. But what is truly singular is, that, as among the Laplanders of Europe we meet with the Finlanders who are white, comely, tolerably tall, and tolerably well made ; so, among the Laplanders of America, we meet with another species of men, tall, well made, tolerably white, and with features exceed- ingly regular. Of a different race from the former seem to be the savages of Hudson's Bay, and northward of the land of Labrador. They are ugly, however, diminutive, and unshapely ; and their visage is almost entirely covered with hair, like the savages of the country of NATURAL HISTORY. ]£5 Yeco, northward of Japan. In summer they dwell under tents made of skins of the rein-deer. In win- ter they live ui.der ground, like the Laplanders and the Samoeids, and, like them, sleep together promis- cuously, and without the smallest distinction. They likewise live to a great age, though they feed on no- thing hut raw meat and fish. The savages of New- foundland have a considerahle resemblance to those of Davis's Straits : they are low in stature : they have little or no beard : their visage is broad and flat : their eyes are large : they are generally rather flat- nosed ; and, upon the whole, are far from being un- like the savages of the north continent, and of the en- virons of Greenland. Besides these savages, who are scattered over the most northern parts of America, we find greater num- bers, and which are perfectly different, in Canada and in the vast extent of land to the Assiniboils. These are tolerably tall, robust, vigorous, and well made. They have hair, and eyes black, teelh, very white, a complexion, tawny, beard, scanty, and over the whole of their body hardly a vestige of hair. They are hardy, indefatigable walkers, and very nimble run- ners. They are alike unaffected by excesses of hun- ger, and of satiety. They are by nature bold and fierce, grave and sedate. So strongly, indeed, do they resemble the Oriental Tartars in the colour of the skin, the hair, and the eyes, in the scantiness of beard, and of hair, as also in disposition, and in manners, that, were they not separated from each other by an immense sea, we should conclude them to be descend- ed from that nation. In point of latitude their situa- tion is also the same, which still farther proves how powerfully the climate influences, not only the colour, but the figure of men. ia6 NATURAL HISTORY. Mr Fabry, who travelled a prodigious way to the north-west of the Mississippi, and visited places which no European had done before him, and of which con- sequently, the savage inhabitants had not been de- stroyed, has assured me, that that part of America is to deserted, that he often travelled a hundred, and two hundred leagues, without observing a single hu- man face, or the smallest vestige of a habitation. He adds, that, whenever he did meet with any habitations they were always at immense distances from one ano- ther ; and that, in each of them, there was frequently not above one family. Sometimes he says there were two or three families, but never above twenty persons together ; and between these twenty persons and twenty others, there was generally a space of a hun- dred leagues at least. To dwell long on the customs of such savage na- tions, would, in my opinion, be unnecessary. It has not been always attended to by author?, that what they have given us for established customs, and for the manners of a community, were nothing more than actions peculiar to a few individuals, and often deter- mined by circumstances, or by caprice. Some nations they tell us, eat their enemies, some burn them, and some mutilate them. One nation, they say, is per- petually at war ; and of another, the grand object is to live in peace ; in one country, the child kills his parent, when he has lived to a certain age ; and in another, the parent eats his child. All these stories, on which travellers have with so much complacency enlarged, mean nothing more than that one savage had devoured his enemy, another had burned or muti- lated him, and a third had killed or eaten his child. All these things may be known to happen in one, as NATURAL HISTORY. 127 well as in several savage nations. For every nation in which there is no government, no law, no master, no habitual society, ought rather to be termed a tu- multuous assemblage of men, barbarous and indepen- dent. Men who obey nothing but their own private passions, and who incapable of having a common in- terest, are also incapable of pursuing one object, and of submitting to fixed and settled usages. If, however, in the whole of North America there were none but savages to be met with, in Mexico and in Peru there were found nations, polished, subjected to laws, governed by kings, industrious, acquainted with the arts, and not destitute of religion. In the present state of these countries, so intermix- ed are the inhabitants of Mexico and New Spain, that we hardly meet with two visages of the same colour. In the town of Mexico, there are white men from Europe, Indians from the north and from the south of America, and negroes from Africa, &c. inso- much, that the colour of the people exhibits every different shade which can subsist between black and white. The real natives of the country arc very brown, and of an olive colour, well made, and active ; and though they have little hair, even upon the eye- brows, yet upon their head, their hair is very long, and very black. In surveying the different appearances which the human form assumes in the different regions of the earth, the most striking circumstance is that of colour. This circumstance has bee nattributed to various causes ; but in my opinion experience warrants us to affirm that the heat of the climate is the principal one. When this heat is excessive, as at Senegal and in Guinea, the inhabitants are entirely black. When it re 1-28 NATURAL HISTORY. rather less violent, as on the eastern coasts of Africa, they arc of a shade more light. When it begins to be somewhat more temperate, as in Barbary, in India, in Arabia &o. they are only brown ; and, when it is altogether tem- perate, as in Europe and Asia, they are white. These varieties are wholly owing to their various modes of living. All the Tartars, for example, are tawny, while the Europeans, who live in the same latitude, are white. Of this difference the reasons seem to be, that the former are always exposed to the air ; that they have no towns, no fixed habitations ; that they sleep upon the earth, and live coarsely in every re- spect. These circumstances alone are sufficient to render them less white than the Europeans, to whom nothing is wanting which may render life comfortable and agreeable. Why are the Chinese more white than the Tartars, whom they resemble in all the fea- tures of the visage? It is because they live in towns, because they are civilized, because they are provided with every expedient for defending themselves from the injuries of the weather, to which the Tartars are continually exposed. When cold becomes extreme, however, it produces some effects similar to those of excessive heat. The Samoeids, the Laplanders, the Greenlanders, are very tawny ; and it is even asserted, as we have already observed, that among the Greenlanders there are men as black as those of Africa. Violent cold, and violent heat, produce the same effect upon the skin ; for these two causes act by one quality, which they pos- sess in common. This quality is dryness ; and as it is a quality of which intense cold is equally productive as intense heat, so by the former, as well as by the latter, the skin may be dried up, altered, and render- NATURAL HISTORY. 129 ed as tawny as what we find it among the Laplanders. Cold compresses, shrivels, and reduces within a nar- row compass all the productions of nature. Hence \ve find the Laplanders, who are perpetually exposed to all the rigours of the most piercing cold, the most diminutive of the human species. The most temperate climate is lietwecn the degrees of forty and fifty. There we behold the human form in its greatest perfection ; and there we ought to form our ideas of the real and natural colour of man. Situ- ated under this zone, the civilized countries are, Georgia, Circassia, the Ukarine, European, Turkey, Hungary, South Germany, Italy, Switzerland, France, and the North of Spain. Of the latter, the inhabitants are the most beautiful, and the most shapely in the * world. As the first, and almost the sole cause of the co- lour of mankind, we ought therefore to consider the climate ; and though upon the skin the effects of nourishment are trifling, when compared with those of the air and soil, yet upon the form they are prodigious. Food which is gross, unwholesome, or badly prepared, has a strong and a natural tendency to produce a de- generacy in the human species. Hence in all coun- tries where the people fare wretchedly, they are more ugly, and more deformed than their neighbours. The air and the soil have also great influences, not only on the form of men, but on that of animals, and of vegetables. In comparing the peasants who live on hilly grounds, with those who live embosomed in the neighbouring vallies, we find, that the former are active, nimble, well-shaped, and lively ; and the women generally handsome. On the contrary, the Vol. I. Q 130 NATURAL HISTORY. latter, in proportion as the air, food, and water arf gross, are clumsy, and less active and vigorous. From every circumstance, therefore, we may obtain ii proof, that mankind are not composed of species es- sentially different from each other. It appears, on the contrary, that there was originally but one indi- vidual species of men, which after being multiplied and diffused over the whole surface of the earth, un- derwent divers changes from the influence of the cli- mate, from the difference of food, and of the mode of living, from epidemical distempers, as also from the intermixture, varied ad infiniium, of individuals more or less resembling each other : at first, these alterations were less considerable, and confined to individuals ; but afterwards, from the continued action of the above causes becoming more general, more sensible, and more fixed, they formed varieties in the species. These varieties have been, and are still perpetuated from generation to generation, in the same manner as cer- tain deformities, and certain maladies, pass from pa- rents to their children. And in short, as these varieties would never have been produced but by a concurrence of external and accidental causes, as they would ne- ver .have been confirmed and rendered permanent, but by timcj and by the continued action of these causes; so it is highly probable, that in time they would in like manner gradually disappear, or even become dif- ferent from what they at present are, if such causes were no longer to subsist. NATURAL HISTORY. 131 CHAP. VII. OF QUADRUPEDS IN GENERAL—OF DOMESTIC ANIMALS THE HORSE THE ASS THE OX THE SHEEP THE GOAT — OF THE SWINE THE WILD BOAR, &c. U PON comparing the various animals of the globe with each other, we shall. find, that Quadrupeds de- mand the rank immediately next ourselves ; and, con- sequently, come first in consideration. The similitude between the structure of their bodies and our own, those instincts which they seem to enjoy in a superior degree to the other classes that live in air or water, their constant services to man, or the unceasing enmity they bear him, all render them the foremost objects of his curiosity, the most interesting part of animated nature. In the first ages of the world it is probable, that all living creatures wero nearer an equality than at present. Man, while yet savage himself, was but ill qualified to civilize the forest. While yet naked, un- armed, and without shelter, every wild beast was a formidable rival, and the destruction of such was the first employment of heroes. But when he began to multiply, and arts to accumulate, he soon cleared the plains of its brute inhabitants ; he soon established an empire over all the orders of animated .nature ; part was taken under his protection and care, while the rest found a precarious refuge in the burning desert of the howling wilderness. The most obvious and simple division therefore of Quadrupeds, is into the domestic and savage ; by do- mestic 1 mean, such as man has taken into friendship, or reduced to obedience; by the savage, those who 132 NATURAL HISTORY. still preserve their natural independence and ferocity ; who either oppose force by force, or find safety in swiftness or cunning. The savage animal preserves at once his liberty and instinct, but man seems to have changed the very na- ture of domestic animals by cultivation and care. A domestic animal is a slave, which has few other de- sires, but those which man is willing to grant it. Humble, patient, resigned, and attentive, it fills up the duties assigned, ready for labour, and content with subsistence. Thus we, in some measure, see'nature under a con- tinual constraint, in those creatures we have taught to live about us ; but it is otherwise when we come to examine the savage tenants of the forest, or the wil- derness; there every species preserves its characteristic form, and is strongly imprest with the instincts and appetites of nature. The more remote from the ty- ranny of mankind, the greater seems their sagacity ; the Beavers, in those distant solitudes, where men have rarely past, exert all the arts of architects and citizens ; they build neater habitations than even the rational inhabitants of those countries can shew, and obey a more regular discipline than ever man could boast ; but as soon as man intrudes upon their society, their spirit of industry and wisdom ceases ; they no longer exert their social arts, but become patient and dull, as if to fit them for a state of servitude. But not only their industry, but their courage is represt by the vicinity of man : the Lion of the de- serts of Nubia, that has been only taught to measure his strength with weaker animals, and accustomed to conquer, i.s possessed of amazing courage ; instead of avoiding man, as other ;miinals are found to do, lie NATURAL HISTORY. 135 attacks whole caravans crossing th< desert, and when over-powered, retires still facing the enemy. But the Lion of Morocco, which is a more popolous country, seems to acknowledge a superiority, arid is even scared away by the cries of women and children. It is in the forest therefore, and remote from man, that we must expect to find those varieties, instincts, and amazing instances of courage and cunning, which Quadrupeds exert in a very high degree. The heads of Quadrupeds are variously formed, corresponding to their different manner of subsisting : in the porcine species, it is sharp, as their food is chiefly under ground : in the canine, which pursue their prey by scent, it is long, in order to afford room for the olfactory nerves : in others, which are fre- quently engaged in combat, it is short and strong, as in the lion. Their teeth also are adapted to the nature of their food : in those which live on vegetables, they are edged before, for cropping grass and herbs: in car- nivorous animals, the fore teeth are sharp, for holding and dividing; and farther in the mouth, they turn broad with unequal, rugged surfaces, to render the aliment fit to assimilate with the fluids in the stomach. Their feet and legs are also adapted to them ; those which live on fish have webbed feet ; and beasts of prey have claws which they can sheathe or unsheathe at pleasure. The stomachs of quadrupeds are formed according to their diet ; those which eat flesh, have it small and glandular, while those which eat vegetables, have it very large. Some animals which chew the cud have four stomachs; but in Africa, where the plants are soft and nutritious, only two. The first aliaient of all quadrupeds is milk, which, is a liquor at once both nourishing, and easily digested, 134, NATURAL HISTORY. this being in carnivorous animals in much less quan- tity than others, the female often carries home her ]>rey alive, that its blood may supply the deficiencies «f nature jn herself. Whatever be the natural disposition of animals at other times, they all acquire new courage and fierce- ness in defence of their young; even the mildest, if wild, will then resist and threaten the invader; but such as have force, and subsist by rapine, are at such times uncommonly terrible. But their care in the protection of their young, is not greater than their sagacity inchusing such month* for bringing forth, as afford the greatest quantity of provision, suitable to the age and appetite of each pe- culiar kind. In general they couple at such times as that the female shall bring forth in the mildest sea- sons, such as the latter end of spring, or the beginning of autumn. The wolf and the fox, for instance, cou- ple in December, so that the time of gestation conti- nuing five months, they may have their young in April. The marc who goes eleven months, admits the horse in summer, and foals in the beginning of May. On the contrary, all those which lay up provisions for the winter, as the beaver and marmot, couple in the latter end of autumn, so as to have their young about January, for which severe season they have already- laid in the proper supplies. This provisional care in every species of quadrupeds, of bringing forth at the fittest seasons, may well excite human admiration; in man the business of procreation is not marked by sea- sons, but brutes seem to decline indeterminate copula- tions, as if conducted less by appetite than the future subsistence of their offspring. NATURAL HISTORY. 135 THE HORSE. THE noblest conquest ever made by man, is that of this spirited animal, which shares with him the fa- tigues of the war, and the glory of the combat. Equally intrepid as his master, the horse sees the dan- ger, and braves it, Inspired at the clash of'arms, he loves it, lie seeks it, and is animated with the same ardour. He feels pleasure also in the chase, in tour- naments, in the course. He is all fire, but equally tractable as courageous, does not give way to his im- petuosity, and knows how to check his inclinations. He not only submits to the arm which guides him, but even seems to consult the desires of his rider; and, always obedient to the impressions which he re- ceives from him, presses on, moves gently, or stops, as Us rider pleases. The horse is a creature which renounces his being, to exist only by the will of ano- ther, which he even knows how to anticipate, and ex- ecute by the promptitude and exactness of his move- ments. He feels as much as we desire, does only what we wish, gives himself up without reserve, and 156 NATURAL HISTORY. refuses nothing, makes use of all his strength, exerts himself heyoncl it, and even dies to obey us. Such is the Horse, whose natural qualities art has improved, which from the earliest ages has heen bro- ken to the service of man. His education commences with the loss of his liberty, and by constraint it is finished. The servitude of these creatures is univer- sal, and so ancient that we rarely see them in their natural state. They are never wholly free from all their bands, not even at the time of rest ; and if they are sometimes suffered to range at liberty in the fields they always bear about them the marks of servitude, and frequently the cruel marks of labour and of pain. The mouth is deformed by the wrinkles occasioned by the bit, the flank scarred with wounds, inflicted by the spur, the hoofs are pierced by nails, and the attitude of the body constrained by habitual shackles. Even those whose servitude is the most gentle, who are on- ly fed and broken for luxury and magnificence, and whose golden chains serve less to decorate them, than to satisfy the vanity of their master, are still more dishonoured by the elegance of their trappings, by the tresses of their manes, by the gold and silk with which they are covered, than by the iron shoes on their feet. Nature is more beautiful than art, and in an ani- mated being, the freedom of its movements makes nature beautiful. Observe the horses in Spanish . America, that live wild ; their gait, their running, or their leaping, seem neither constrained nor regular. Proud of their independence, they fly the presence of man, and disdain his care. They wander about in liberty, in immense meads, where they feed on the fresh productions, of an eternal spring. Destitute of NATURAL HISTORY. 1.0? finy fixed habitation, without any other shelter than a mild sky, they breathe a purer air than those that are confined in vaulted palaces. These wild horses are also much stronger, much swifter, and more ner- vous, than the greater part of domestic horses. They have, what nature has bestowed upon them, strength and nobleness. The others, only what art can give, beauty and cunning. The natural disposition of these animals is not fe- rocious, for though superior in strength to the great- est part of animals, they never attack them ; and if they are attacked by others, they either disdain them or trample them under their feet. They herd toge- ther, as they are not fearful of but fond of one ano- ther. As herbs and vegetables are sufficient for their nourishment, they have quite enough to satisfy their appetite ; and as they have no relish for the flesh of animals, they never make War with them, nor with themselves. They live in peace, because their appe- tite is simple and moderate ; and, as they have enough, there is no room for envy. As all parts of Europe are at present peopled, and almost equally inhabited, wild horses are no longer found there ; and those which we see in America, were originally European tame horses, which have multiplied in the vast deserts of that country. The astonishment and fear which the inhabitants of Mexico and Peru expressed at the sight of horses and their riders, convinced the Spaniards that this animal was entirely unknown in these countries. They therefore carried thither a great number as well for service, and their particular utility, as to propagate the breed. M. de la Salle, in 1685, saw, in the northern parts of America, near the Bay of St Louis, whole troop* Vol. L R 138 NATURAL HISTORY. of these wild horses feeding in the pastures, which were so fierce that nobody durst approach them. The Author of the History of the Adventures of the Buc- csneers, says, that in the island of St Domingo, hors- es may sometimes he seen in troops of upwards of five hundred running together, and that as soon as they see a man, they will stop.. He adds, that one of them will approach to a certain distance, snort, take flight, and then all the rest will follow him. To catch them, they make use of nooses made of ropes, which they spread and hang in places which they know they frequent. If they are caught by the neck they strangle themselves, unless (.he huntsman hastes their assistance, who instantly secures them by the to body and the legs, and fastens them to trees, where they are left ior two days without either food or drink. This experiment is sufficient to begin to make them tractable and in time they become a« much so as if they had never been wild ; and even, if by chance they ever regain their liberty, they kno'.Y their masters, and suffer them to catch them again without trouble. The manners of these animals almost wholly de- pend on their education. From time immemorial it has been the custom to separate the colts from their mothers after they have suckled them five, six, or seven months ; for experience has taught, that those colts which are suckled ten or eleven months, are not of equal value with those which are weaned sooner, though they are generally fuller of flesh. After six or seven months sucking, they are weaned, that they may take more solid nourishment than milk. Bran is then given them twice a-day, and a little hay, of which the quantity is increased in proportion a* they NATURAL HISTORY. 139 advance in age, and they are kept in the stable as long as they seem to retain any desire to return to the mare ; but when this desire ceases, they are suf- fered to go out in fine weather, and led to pasture. Care, however, must be taken not to suffer them to go out to pasture fasting. They must have bran, and be made to drink an hour before they are suffered to graze, and are never to be exposed to great cold or rain. In this manner they spend the first winter. In the May following, they are not only permitted to graze every day, but are suffered to lie in the fields all the summer, and even to the end of October, only they must not be allowed to eat the after-grass ; for if they accustom themselves much to it, they will grow disgusted with hay, which ought, however, to be their principal food during the second winter, to- gether with bran mixed with barley, or oats wetted. They are managed in this manner, letting them graze in the day time during winter, and in the night also during the summer, till they are four years old, when they are taken from the pastures, and fed on hay. This change in food requires some precaution ; for the first eight days, the colt should have nothing but straw and it is proper to administer some vermifuge drinks, as those insects may have been generated from indi- gestion, and green food. Great attention must be paid in weaning young colts, to put them into a proper stable, not too hot, for fear of rendering them too delicate arid sensible to the impressions of the air. They should frequently have fresh litter, and be kept very clean, by rubbing them often down with a wisp of straw. But they should not be tied up or curried till they are two years and a half, or three years old; for this gives 140 NATURAL HISTORY. them great pain, their skin being too delicate to bear it, and they would fall away instead of growing fat from it. Care too must be taken that the rack and manger are not very high, the necessity of raising their heads too high in order to reach their food, may possibly give a habit of carrying it in this fashion, which would give them an auk ward appearance. At the age of three years, or three and a half, the rider should begin to break them and make them tractable. They should at first have a light easy saddle, and ought to wear it two or three hours every day, and they should be accustomed to have a snaffle bit in their mouths, and to lift up their feet, on which they should sometimes receive rather smart strokes, and if designed for coach or draught horses, should wear harness and a bridle. At first a curb should not be used, they should be held by a leather strap, and be made to trot, on even ground, without a rider, and with only the saddle or harness on the body. When the saddle horse turns easily, and willingly follows the person who holds the leather strap, the rough ri- der should mount him and dismount again in the same place, without making him move, till he is four years old, because, before that age, the weight of a man overloads him ; but at four he should be made to walk or trot, a little way at a time, with the rider on his back. When a coach horse is accustomed to the harness, he should be paired with a horse that is tho- roughly broke, putting on him a bridle, with a strap passed through it, till he begins to be used to the draught. After this the coach-man must teach him to back, having the assistance of a man before, who must push him gently back, and even give him some blows t,o make him do it. All this should be done before NATURAL HISTORY. 141 young horses hare changed their food, for when once they are what is called corn-fed, that is, when they feed on grain and hay, as they are more vigorous, it is remarked also that they are less tractable, and more difficult to break. The bit and the spur are two means made use of to bring them into subjection. The mouth does not appear formed by nature to receive any other impres- sions than that of taste and appetite ; there is, howe- ver, so great a sensibility in the mouth of a horse, that in preference to the eyes and ears, we address ourselves to it, to make him understand our pleasure. The smallest motions or pressure of the bit, is suffici- ent to inform and determine the animal ; and this or- gan of sense has no other fault than its perfection. Its too great sensibility must be managed, for if it is abused, the mouth of the horse is rendered insensible to the impression of the bit. The senses of sight and hearing are not subject to such a change, and could not be dulled in this manner; but, it has been found inconvenient to govern horses by these organs, and it is generally true, that signs given them by the sense of feeling have more effect on animals in general than those conveyed by the eyes or ears. Besides, the si- tuation of horses with relation to those who mount or conduct them, makes their eyes almost useless for this purpose, because they see only straight forwards. Hence they could only perceive the signs made to them when they turned their heads round ; and al- though they are frequently conducted and animated by the ear, yet in fact, if they are well broken, the smallest pressure of the thighs, or most trifling motion of the bit, is sufficient to direct them. The spur is the hind leg rises. Because in the amble, the fore leg ,ris«s, at the same time with the hind kg on the same sides: instead, of which, in trotting, the foreleg «n the saan.e side rests and assists. the impulse during ihts whole time.. that: the- hind. leg. is in NATURAL HISTORY. 147 Of all the large animals, the horse has the greatest proportion and elegance in every part of the body. The great length of the jaws is the principal cause of the difference between the heads of quadrupeds and of the human species. It is also the most ignoble mark of all ; yet, though the jaws of the horse are very long, he has not, like the ass, an air of imbecility, or of stu- pidity like the ox. The regularity of the proportions of Ins head, on the contrary, gives him an air of sprightliness, which is well supported by the beauty of his chest. The horse seems desirous of raising him- self above his state of a quadruped, by holding up his head, and in this noble attitude he looks man in his face. His eyes are lively and large, his ears well made, and of a just proportion, without being short like those of the bull, or too long like those of the ass. His mane suits well his head, ornaments his neck, and gives him an air of superiority. His long bushy tail covers and terminates advantageously the extremities of his body, far different from the short tails of the stag, the elephant, £c. and the naked tails of the ass, the camel, the rhinoceros, &c. The tail of the horse is formed of long, thick hair, which seems to come from his rump. He cannot raise his tail like the lion, but it suits him better hanging down, as he can move it sideways. It is very useful to him to drive away the flies which incommode him, for though his skin is very hard, and is every wtiere furnished with a close thick coat, it is extremely sensible. The head of a well-proportioned horse should be lean and small, without being too long. The ears should be at a moderate distance, small, straight, immoveable, narrow, thin, and well placed on the top of the head. The forehead should be narrow, and a little convex* 148 NATURAL HISTORY. Hollows should be filled up, the eye-lids thin, the eyes clear, lively, full of fire, rather large, and projecting from the head ; the pupil large, the nether jaw thin, the nose a little aquiline, the nostrils large and open, the partition of the nose and the lips thin. The mouth ought to be of a moderate width, the withers raised and sloping, the shoulders thin, flat, and not confined, the back equal, even, and insensibly arched length- ways, and raised on each side of the spine, which should appear indented. His flanks should be full and short, the rump round and fleshy, the haunches well covered •with hair, the stump of the tail thick and firm, the fore legs and thighs thick and fleshy, the knees round before, the houghs large and rounded, the sinew loose, the joint next the foot small, the fetlock not thickly covered with hair. The pastern ought to be large, and of a middling length, the coronet rather raised, the hoof black, smooth, shining, and high, the quarters round, the heels wide and moderately raised, the frog small and thin, and the sole thick and hollow. But there are few horses in which this assemblage of perfection is to be found. The eyes are subject to many complaints, which are sometimes difficult to be known. In a healthy eye, we ought to see through the cornea two or three spots of the colour of soot, above the pupil. To see these spots, the cornea must be clear, clean, and transparent ; if it appears double, or of a bad colour, the eye is not good. A small, long, and straight pupil, encompassed with a white circle, is also a bad sign, and when it is of a blueish- green colour, the eye is certainly bad and the sight dull. I shall at present only add some remarks, from which, as well as from the preceding, a judgment NATURAL HISTORY. U9 may be formed of the principal perfections or imper- fections of a horse. It is very easy to judge of the natural and actual state of the animal by the motion of his ears. When he walks, he should project for- wards the points of his ears. A jaded horse carries his ears low ; those which are spirited and mischiev- ous, alternately carry one of their ears forwards and one backwards. They all carry their ears on that side from which they hear any noise, and when any one strikes them on the back, or on the rump, they turn their ears back. Horses which have the eyes deep sunk in the head, or one smaller than the other, have usually a bad sight. Those which have the mouth dry, are not of so healthy a temperament as those which have the mouth moist, and make the bri- dle frothy. A saddle horse ought to have the shoul- ders flat, moveable, and not very fleshjfc A draught horse, on the contrary, should have them flat, round, and brawny. If, notwithstanding, the shoulders of a saddle horse are too thin, it is a defect which shews the shoulders are not free, and consequently the horse cannot bear fatigue. Another fault of a saddle horse is, to have the chest project too far forward, and the fore legs drawn too much back, because he is apt to rest on the hand in galloping, and even to stumble and fall. The length of the legs should be propor- tionable to the height of the horse ; when the fore legs are too long, he is not sure footed ; if they are too short, he is too heavy in the hand. It is remarked that mares are more liable than horses to be short- legged, and that horses in general have the legs thicker than mares or geldings. The age of the horse is known from his teeth. He has forty ; twenty-four grinders, four eye teeth, and twelve Incisive teeth. Mares have no eye teeth, or if 150 NATURAL HISTORY. ihey have them they are very short. The grinders, are not instrumental to the knowledge of their age, •we form our judgment from the front and eye teeth. The twelve front teeth begin to shew themselves fif- teen days after the birth of the foal ; these first teeth are round, short, weak, and drop out at different times iii order to make room for others. At two years and a half the four front middle teeth drop out the first, two at top and two at bottom ; a year after, four others fall out, one on each side of those which are al- ready replaced, At about four years and a half, four others drop out, always on the side of those which have been replaced ; these four last milk teeth are re- placed by four others, which do not grow near so fast as these which replaced the first eight ; and these four last teeth, which are called the wedges, and which replace the fouj last milk teeth, are those by which we know the age of a horse. These are easily known, since they are third as well at top as at bottom, be- ginning to count from the middle of the extremity of the jaw. These teeth are hollow, and have a black mark in their concavity. At four years and a half, or five years old, they scarcely project beyond the gums, and the hollow is plainly seen. At six and a half it begins to fill up, the mark also begins to di- minish and grow narrower, and so continues till seven years and a half or eight years, when the hollow is- entirely filled up, and the black mark effaced. After the animal has attained eight years, as these teeth do not give further information of the age, we generally judge by the eye teeth, cr tusks. These four teeth are placed at the side of those which I have just now- taken notice of. the eye teeth, as well as the grind- ers, are not preceded by others which fall out, those NATURAL HISTORY. t;>f of the inferior jaw usually come out first at three years and a half, and the two of the upper jaw at four years, and till they are six years old they are ve- ry sharp. At ten years old the upper ones appear already blunt, worn, and long, because they are bare, the gum wearing away with age. and the more they are worn away, the more aged the horse is. From ten till thirteen or fourteen years, there is hardly any indication of the age, but then some hairs on the eye- brows begin to grow white ; but this indication is equivocal, since it has been remarked that horses en- gendered from old stallions and old mares have the hair white on the eye-brows at ten years old. There are also horses whose teeth are so hard that they do not wear, and upon which the black mark subsists, and is never effaced ; and others which have the mark in the mouth as long as they live. We may also know, though with less precision, the age of a horstf by the ridges of the palate, which are effaced in pro- portion to his age. It has been remarked, that studs kept in dry and light countries produce good-tempered, swift, and vi- gorous horses, with nervous legs and hard hoofs ; while, on the other hand, those which are bred in damp places, and in fat pasturage, have generally the head' large and heavy, the legs thick, the hoofs soft, and* the feet flat. This difference arises from the climate and food ; but, what is more difficult to be accounted for, and what is still more essential than any thing" that has been said, is, the necessity of always cros- sing or mixing the breed, if we would prevent their degenerating. 'Mares usually go with foal eleven months and some days ; they will breed commonly to the age of fourteen 152 NATURAL HISTOtlY. or fifteen years, and the more vigorous till they are a- bove eighteen years. The duration of the life of horses is like that of every other species of animals, in proportion to the length of the time of their growth. Man who is a- bove fourteen years in growing, lives six or seven times as long, that is ninety or a hundred years. The horse who attains his full growth in four years, lives six or seven times as long, that is twenty-five or thirty years. There' are so few examples to contradict this rule, that we should not even regard them as exceptions from which we may draw any precedents. It is wor- thy of remark too, that as robust horses arrive at their full growth in less time than delicate ones, they also live less time, and at fifteen years of age are old. The Arabian horses are the handsomest known in Europe, they are larger and plumper than those of Barbary, and equally well-shaped, but as they are not •ften brought into this country, riding-masters are not able to give an exact account of their perfections and defects. The horses of Barbary are more common. They are frequently negligent in their paces, and must be often reminded. They are very swift and strong, light, and fit for ^hunting. These horses seem the most proper to breedTrom ; it were only to be wished that they were larger, as they seldom exceed four feet eight inches high. The Turkish horses are not so well proportioned as those of Barbary. They will, however, travel a great •way, and are long-winded. This is not surprising, if Ave consider, that in warm countries the bones of ani- mals, are harder than in cold climates, and it is for this reason that they have more strength in the legs. NATURAL HISTORY. us The Spanish horses hold the second rank after those of Bafbary. Those of a handsome breed are plump, well-coated, a,nd low. Their movements are likewise quick and supple, and they are remarkable for spirit and boldness. Their hair is usually black, or of a bay chesnut colour, though there are some of all co- lours, and it is but seldo/n that they have white le^s and noses. The Spaniards, who have an aversion to these marks, never breed from horses that havo them, choosing only a star in their forehead. The handsomest English horses ha-re in their con* formation great resemblance to thoss of Arabia and Barbary, from which they originally sprung. They are frequently five feet high ; and above. They are of all colours, and have all kinds of marks ; they are generally strong, vigorous, bold, capable of great fa- tigue, and excellent for hunting and coursing. The horses of Italy were formerly much handsomer than they are at present, because the breed for some time has been neglected. Notwithstanding this, there are still some handsome Neapolitan horses, especially draught ones ; but, in general, they have the head large, and the chest thick. They are untrartaWe, and consequently not easily managed ; but these defects are compensated by their noble form, thtir statcliness and the beauty of their motions. The Danish horses are :-o handsome in their form, and so beautiful in their coats, that they an? preferred to all others fbt putting into carriages. They are of all colours, and even of some singular ones, as pied. Horses, however, spotted like tigers, are found no where but in Denmark. In Germany we meet with very handsome horses ; but they are generally heavy and short-breathed. Vol. I. T 154 NATURAL HISTORY. The Hussars and Hungarians split their nostrils, ii; order, they say, to give them more breath, and also to hinder their neighing in battle. The Flemish horse* are greatly inferior to those of Holland : they have almost all large heads, flat feet, and are subject to humours in the eyes ; and these two last are essential defects in coach- horses. According to Marmoi, the Arabian horses are de- scended from the wild horses of the deserts of Arabia, of which, in ancient times, large studs were formed, which have multiplied so much, that all Asia and Af- rica are full of them. They are so nimble, that some will outstrip the very ostriches in their course. The Arabians of the desert, and the people of Lybia, breed a great number of these horses for hunting, but they neither use them, in travelling nor in their wars ; they send them to pasture whilst there is grass for them ; and when that fails, they feed them only with date*. and camel's milk, which make them nervous, nimble, and lean. They lay snares- for the wild horses, and eat the flesh of the young ones, which they affirm to be very delicate food. These wild horses are smaller than the tame ones, and are commonly ash-coloured, though there are also some whke ones, and the mane and the hair of the tail is sho*t and frizzled. Let an Arabian be ever so poor, he has horses. They usually mount the mares, experience having taught them that they bear fatigue, hunger, and thirst, lietter than horses. The Turks, on the contrary, do not approve of mares ; and the Arabians sell them the horses which they do not keep for stallions. They have long preserved, with great care, the breed ofNtheir horses ; they know all their genealogy, and distinguish the brreds by f'itlirjon* mime;:. The Jcvrest price for NATURAL HISTORY. 155 are of the first clas?, is from one hundred, to tw» rr three hundred pounds sterling. As the Arabians have only a. tent for their house, it serves them also for a stable. The mare, colt, husband, wife, and chil- dren, lie promiscuously together; and the little chil- dren will lie on the body and neck of the mare and colt, without being in the least injured. These mares are so accustomed to live in this familiarity, that they will suffer any kind of play. The Arabians treat them kindly, talk and reason with them, and take great care of them, always let them walk, and never use the spur without necessity. Hence, as soon as they feel their flank tickled with the stirrup-iron, they set out immediately with incredible swiftness, and leap hedges and ditches with great agility. But if the rider happens to fall, they are so well trained, that they will stop short even in the most rapid gallop. All Arabian horses are of a middling size, very easy in their manner, and rather thin than fat They are dressed morning and evening regularly, with so much care, that not the smallest spot is left on their skins. Their legs, mane; arid tail, are also washed, which they let prow long, and seldom comb, to avoid breaking the hairs. They have nothing given them to eat all day, and seldom are allowed to diink above two or three times. At sunset, a bag is fastened round their heads, in which is about half a bushel of very clean barley. These horses, therefore, eat only during the night ; ami the bag is not taken from them till the next morning, when all is eaten up ; and, in the month nf March, when the grass is tolerably high, they are turned out to pasture. As soon as the spring is past, they are taken again from pasture, and have neither igrass nor oats all the rest of the year, and straw bui, 556 NATURAL HISTORY. seldom, barley being their only food. They do not neglect to cut the mane of the colts as soon as they are a year or eighteen months old, in order to make it grow thick and long. They mount them at t\vo years old, or two years and a half at most. Till this age they put neither saddle nor bridle on them ; but after it, all the Arabian horses stand saddled at the door of the tent, every day, from morning to night. The breed of these horses is dispersed in Barbary, among the Moors, and even among the Negroes of the riv«r Gambia and Senegal. The principal people of the country have some which are of uncommon beauty. Instead of barley or oats, they give them maize reduced to flour, which they mix witli milk, when they are in- i lined to fatten them ; and in this hot climate they seldom let them drink. The Tartars live with their horses nearly in the Game manner as the Arabians do. When they are a- Ixnit seven or eight months old, the young children mount them, and make them walk and gallop a little way by turns. They thus break them by degrees, and oblige them to submit to long fastings ; but they never mount them for racing or hunting till they are six or seven years old, and then make them support incredible fatigue, such as travelling two or three days together without stopping, passing four or five with- out any other food than a handful of grass every eight hours. They also inure them to go twenty-four with- out drinking. These horses, which appear, and w.hich are actually so robust in their own country, become enfeebled, and are soon good for nothing when trans- ported to China or the Indies ; but they succeed bet- ter in Persia and Turkey. In lesser Tartary they J»ave also a breed of smali horses, which are in such NATURAL HISTORY. 157 •estimation, that they are not allowed to sell them to foreigners. These horses have all the good and bad qualities of these of Great Tartary, which shews how much the same manners, arid the same education give the same disposition to these animals. There are also in Circassia, and in Mingrelia, many horses which are even handsomer than those of Tartary. There are also found some handsome horses in the Ukraine, Walachia, Poland, and Sweden ; but we have no par- ticular account of their qualities and defects. When the horse is inflamed with love, desire, or ap- petite, he shews his teeth, and seems to laugh. He shews them also when he is angry, and would bite. He sometimes puts out his tongue to lick, but less frequently than the ox, who licks much more than the horse, and who, notwithstanding, is less sensible to caresses. The horse also remembers ill treatment much longer than the ox ; his natural disposition and courage are such, that, when he finds more is expected from him than he is able to perform, he is irritated, and will not exert himself. Instead of which, the ox, who is slow and idle, exerts himself, and is more easily tired. The horse sleeps much less than man ; for when he is in health, he does not rest more than two or three hours together. He then gets up to eat ; and when he is satisfied, he lies down a second time ; but he does not sleep more than three or four hours in the twenty-four. There are even some horses who never lie down, but sleep standing. It has also been re- marked, that geldings sleep oftener and longer than horses. Quadrupeds do not all drink in the same manner, though they are all equally obliged to seek with the •:S8 NATURAL HISTORY. head for the liquor, except the monkey, macaw, arid some others that have hands, and consequently drink, like men, when a vase or glass is given them which tiiey can hold. They carry this to their mouths, in- clining the head, throwing down the liquor, and swal- lowing it by the simple motion of deglutition. Man usually drinks in the same manner, because it is most convenient. Most quadrupeds also -choose that mode which is most agreeable to them, and constantly fol- low it. The dog, whose mouth is large, and whose tongue is long and thin, drinks lapping, which mode he prefers to that of wetting the nose. The horse, on the contrary, whose mouth is small, and whose tongue is too short and thick to scoop it up, and who always drinks with more avidity than he eats, dips the mouth and nose quickly and deeply into the water, which he swallows largely by the simple motion of deglutition. This, however, forces him to drink with- out breathing; whilst the dog breathes at his ease while he is drinking. Horses therefore should be Suffered to take seteral draughts, especially after running, when respiration is short and quick. They should not, how- ever, be suffered to drink the water too cold, because that, independently of the cholic, which cold water frequently occasions, it sometimes happens also, from the necessity they are in of dipping the nose into the water, that they catch cold, which often lays the foun- dation of a disorder called the glanders, the most for- midable of all to the horse. As the seat of the glan- ders is in the pituitary membrane, it is consequently a real cold, which occassions an inflammation in this membrane. Travellers too, who give us a detail of the maladies of horses in warm climates, as in Arabia, Persia, and Barbary, do not say that the glanders arc NATURAL HISTORY. so frequent there as in cold climates. It is from this- therefore that the conjecture arises, tiiat this malady is occasioned hy the coldness of the water, because these animals are obliged to dip and keep the nose and nos- trils a considerable time under it. This, however, might be prevented by never giving it to them cold, and by always wiping the nostrils after drinking. Asses, who fear the cold more than horses, and resemble them so strongly in the interior structure, are, notwithstanding, not so subject to the glanders. This may possibly liappen from their drinking in a different manner from horses ; for, instead of dipping the mouth and nose deeply into the water, they scarce- ly touch it with their lips. I shall not speak of the other diseases of horses. It would extend this Natural History too much ta join to the history of an animal that of its disorders : nevertheless, I cannot leave the history of the horse, without regretting that the health of this useful ani- mal should have been hitherto abandoned to the care, and frequently absurd practice, of ignorant people. The branch of physic which the ancients called V7ete- rinarian, is at present scarcely known but by name. Were some physician to direct his views this way. and make this study his principal object, he would soon find it answer his purpose, both with respect to reputation and profit. Instead of degrading himself, he would render his name illustrious ; and this branch of physic would not be so conjectural and difficult as the other. All causes being more simple in animals than in man, the diseases ought also to be less com- plicated, and conseauently treated with more gut- ters. 16*0 NATURAL HISTORY. THE ASS. IF we consider this animal with attention, he ap* pears only to be a horse degenerated. The perfect similitude in the conformation of the brain, the lungs, the stomach, the intestinal conduit, the heart, the li- ver, and other viscera, and the great resemblance of the body, legs, feet, and the entire skeleton, is a suf- ficient foundation for this opinion. We may even at- tribute these slight differences which are found be- tween these two animals, to the influence of the cli- Inate, food, and the fortuitous succession of many ge- nerations of small wild horses, half degenerated, which by little, have still continued to degenerate so far as at last to produce a new and fixed species ; or rather, a succession of individuals, all vitiated in the same manner. What appears to favour this notion is, that as horses vary much more than asse^ in the colour of their skin, they are consequently more anciently domes- tic, since all domestic animals vary* much more in their colour than wild ones of the same species. Besides, the greater number of wild horses, of which travellers NATURAL HISTORY. 161 *peak, are small in their size, and have, like assts, the voat grey, and the tail naked and frizzled at the end. They also mention wild horses, arid even domestic ones, \vhich have a black stripe on the back, and other marks which nearly resemble both wild and domestic asses. Again, if we consider the difference of the temper- ament, disposition, the manners, the organism, of these two animals, and, above all, the impossibility of mixing the breed to make one common species, or even an intermediate species which may be renewed, it ap- pears a better-founded opinion, to think that these ani- mals are of a species equally ancient, and originally as different as they are at present. The ass differ* materially from the horse, in the smallness of the size, largeness of the head, length of the ears, hardness of the skin, nakedness of the tail, the form of the rump, and also in the dimensions of the neighbouring parts ; such as the voice, the appetite, manner of drinking, &c. Do the horse and the ass, then, come originally from the same stock ? are they of the same family, or not f and have they not always been different animals ? When two individuals cannot produce together, we can no otherwise account for it, but from a slight dif- ference in their temperament, or some accidental fault in the organs of generation, of one or other of these two individuals. That two individuals of different species, should produce other individuals which do not resemble the one or the other in any fixed particular, and can consequently produce nothing like themselves, there needs but a certain degree of conformity between the form of the body and the organs of generation of these different animals. But what an immense num- ber of combinations are necessary, even to suppose that two animals, male and female, of a certain spe- VoLL U NATURAL HISTORY. cies, are no longer able to produce with those of their o.wn kind, but are even degenerated to such ;i degree that they can only produce together ; and also, whal a prodigious immensity of combination j ;ire necessary that the production of these two degenerated animals should follow exactly the same laws which are ob- served in the production of perfect animals; for a de- generated animal is itself a vitiated production ; and how can a vitiated, depraved origin, become a stock, and not only produce a constant succession of beings, but even produce them in the same manner, and fol- lowing the same laws, which in effect reproduce the Animal, the origin of which is pure ? Although we cannot demonstrate that the production of a species, by degeneration, is a tiling impossible in nature, yet the number of probabilities on the contrary is so great, that we can no longer doubt of it. For if some species have been produced by the degcm ra- tion of others, if the species of the ass is derived fiojn ijie species of the horse, this can only have happened (successively. By degrees, therefore, there would havti been, between the horse and the ass, a great number of intermediate animals, the h'rst of which would have 4iffcrcd but slightly in its nature from the horse, and the latter would lujve approached by degrees to that of the ass. Why then do we not si-e the nipr> tjves, the descendants of the intermediate s; i why do only the two extremes remain? The ass is then an ass, and not a horse degenerated. He is neither a stranger, an intruder, nor a bastard. He has hjs family, his species, and his rank. I lib blood is pure; and although his nobility is less illus- trious, yet it is equally good, equally ancient with that of the horse. Why, then, have we so much con- NA'IVKAL HISTORY. luS tempt for this animal ; so good, so patient, so steady, so useful ? Do men awry (heir contempt even to ani- mals, those which serve them so well, and at so small an expense ? We take care of, we instruct, and ^ exercise the horse, whilst the ass is ahandoned to the care of the lowest servant, or the tricks of children. Thus, instead of improving, he must lose by his edu- cation ; and if there were not a fund of good qualities, he would certainly lose them hy the manner in which he is treated. He is the May game of the rustics, who beat him with stall's, overload him, and make him work beyond his strength. We do not consider, that he would be the most beautiful, the best-formed, and most distinguished of the lower animals, if there were no horses in the world. We forget that he is an ass, that he has all the qualities of his nature, all the gifts attached to his species ; and at the same time, \ve only think of the figure and qualities of the horse, which he ought not to have. He is naturally as humble, patient, and quiet, as the horse is proud, ardent, and impetuous. He suf- fers with constancy, and perhaps with courage, chas- tisement and blows. He is moderate both as to the quantity and quality of his food. He is contented with the hardest and most disagreeable herbs, which the horse, and other animals, will leave with disdain. He is very delicate with respect to his water, for he will drink none but the clearest, and from rivulets with which he is acquainted. He drinks as moderately as lie eats, and does not put his nose in the water (through fear, as some say, of the shadow of his ears). As care is not taken to curry-comb him, he frequently rolls himself on the grass, thistles, and in the dust; and, without regarding his load, he lays himself down 164 NATURAL HISTORY. to roll about as often as he can, and by this seems to reproach his master, for the little care he takes of him, In his earliest youth, he is sprightly, and even hand- some, light, and genteel ; but, either from age or baj^ treatment, he soon loses it, and becomes slow, indo- cil, and headstrong. Pliny assures us, that when they separate the mother from the young one, she will go through fire to recover it. The ass is also strongly attached to his master, notwithstanding he is usually ill-treated. He will smell him afar off, and can dis- tinguish him from all other men. He also knows the places where he has lived, and the ways which he has frequented. His eyes are good, and his smell is acute. His ears are excellent, which has also contributed to hid being numbered among timid animals, which it is pretended have all the hearing extremely" delicate, and the ears long. When he is over-loaded, he shews it by lowering his head, and bending down his ears : when he is greatly abused, he opens his mouth, and draws back his lips in a most disagreeable manner, which gives him an air of derision and scorn. If his eyes are covered over, he remains motionless. He walks, trots, and gallops like the horse ; but all his motions are smaller, and much slower. Notwithstand- ing he can run with tolerable swiftness, he can gallop but a little way, and whatever paces he uses, if he is hard pressed, he is soon fatigued. The Jack-ass brays in a very discordant manner. The she-ass has a clearer and shriller voice. Those that are gelded, bray very low ; and, though they seem to make the same efforts, and the same motions of the throat, yet their cry cannot be heard far off. Of all the animals covered with hair, the ass is least subject to verinir. This circumstance may be NATURAL HISTORY. 165 attributed to the hardness and dryness of the skin, which is certainly harder than in the greatest part of other quadrupeds. He is much less sensible than the horse to the whip and the sting of the flies. At two years and a half old, the first middle incisive teeth fall out, and afterwards the other incisive at the side of the first fall also, and are renewed at the same time and in the same order as those of the horse. The age of the ass is also known by his teeth. The third incisive on each side ascertains it, as in the horse. The ass is three or four years in growing, and lives twenty-five or thirty years. He sleeps less than the horse, and does not lie down to sleep, except when quite tired. Thsre are among asses different races, as among horses ; but they are much less known, because they have not been reared with the same attention ; but we cannot doubt that they came all originally from warm climates. Aristotle assures us, that there were none in his time in Scythia, nor in the other neigh- bouring countries, nor even in Gaul, which, he says, is a cold c'.imate. He adds too, that a cold climate, either prevents them from procreating their species, or makes them to degenerate ; and that this last circum- stance is the reason that they are small and weak in lllyria, Thrace, and Epirus. They appear to have come originally from Arabia, and to have passed from Arabia into Egypt, from Egypt into Greece, from Greece into Italy, from Italy into France, and after- wards into Germany, England, and lastly into Sweden, &c. for they are, in fact, weak and small in propor- tion to the coldness of the climate. The Latins, after the 'Greeks, have called the wild ass, angra ; which animal must not be confounded, us f6(j NATURAL HISTORY. force naturalists and many travellers have done, with the zehra. The angra, or wild ass, is not striped like the fcebra, and is not near so elegant in figure. Wild ;isses are found in some of the islands of the Archipel- ago, and particularly in that of Cerigo. There are also many in the deserts of Lybia, and Numidia. They are grey, and run so fast, that the horses of Barbary only outstrip them in the chase. When they see a man, they give a loud cry, turn themselves a- bout, and stop, and do not attempt to fly till he ap- proaches pretty near them. They are taken in snares made with ropes, and go in troops both to pasturage and to drink ; their flesh is also eaten. There were also, in the time of Marmol, wild asses in the island of Sardinia, but less than those of" Africa; and Pietro della Valle said, he has seen a wild horse at Bassora, whose figure differed in no respect from a domestic one. He was only of a lighter colour, and had, from the head to the tail, a stripe of white ; he was also much livelier, and lighter in hunting, than the greater number of asses. Neither asses nor horses have been found in Amer- ica, although the climate, especially of North America, is as good for them as any other. Those which the Spaniards have transported from Europe, and which they have left in the West Indies, and on the conti- nent, have greatly multiplied ; and in some parts wild asses are found in troops, and are taken in snares like wild horses. The ass with the mare produces large mules, and the horse with the she-ass produces small mules, dif- fering from the first in many respects. As wild asses are unknown in these climates, we cannot actually say whether the flesh is good to eat ; NATURAL HISTORY. 167 but it is certain, that the flesh of the domestic ass is 'extremely bad, and harder than that of the horse. The milk of the ass, on the contrary, is an approved and specific remedy for certain complaints, and its use is known from the Greeks to us. That it may be good in its kind, we should choose a young healthv she-ass, full of flesh, that has lately foaled, and which has not since that period been with the male. Care must be taken to feed her well with hay, wheat, and grass. The milk must not be exposed to the air, which will spoil it in a short while. The skin of the ass is used for different purposes, such as to make drums, shoes, and thick parchment for pocket-books, which is slightly varnished over. It is also with the skins of asses that the Orientals make the sagri, which we call shagreen. The ass is, perhaps, the animal which can carry the greatest weight. As it costs but little to feed him, and as he scarcely requires any care, he is of great use in the country. He also serves fo ride on, as all his paces are gentle, and he stumbles less than the horse. He is frequently put to the plough in countries where the earth is light, and his dung is an excellent manure. 368 NATURAL HISTORY. THE BULL. 27/E COW. THE ox,* and other herbiverous animals are not only the most useful to man, but they are also main- tained at the least expense. The ox is the most ex- cellent in this respect, for he restores as much to the * The word Ox, in its common acceptation, denotes Black Cattle ii> peneral without regard to sax. l,u a more restricted se,ns« , it si£:iiSes a Bull. NATURAL HISTORY. 169 earth as he takes from it, and even enriches the ground on which he feeds. That the ox is not so proper as the horse, the ass, .•nid the camel, for carrying burthens, the form of his back and loins is a demonstration. But the thickness of his neck, and the broadness of his shoulders point him out as destined for the yoke. In some places they make him draw by the horns. In support of this practice, it is alledged that when yoked in this manner he is more easily managed. His head is very strong, and he draws well by the horns, but with much less advantage than by the shoulders. Nature seems to have destined him for the plough. The size of his body, the slowness of his motions, the shortness of his legs, and even his tranquillity and patience when he labours, seem to concur in rendering him proper for the cultivation of the fields, and more capable than any other of overcoming the constant resistance that the earth opposes to his efforts. In those species of animals, which man has formed into flocks, and where the multiplication is the princi- pal object, the female is more useful than the male. The produce of the cow is renewed every instant. The flesh of the calf is wholesome and delicate. The milk is the food of children ; butter relishes the most of our dishes, and cheese is the common food of the peasants. The cow arrives at the age of puberty in eighteen months, and the bull in two years. .But they should not be admitted to each other till they be three years old. From three to nine years these animals are in their greatest vigour. After this, neither cows nor bulls are fit for any thing but to fatten for the slaugh- ter, as at two years of age they are almost at their Vol. I. X 170 NATURAL HISTORY. full growth. The length of their lives is also, like that of the greatest part of the other species of ani- mals, about fourteen years, and they seldom live above fifteen. The dullest and most idle animals are not those which sleep the soundest, or the longest. The ox sleeps, but his sleep is short, and not very sound; for he awakes at the least noise. He usually lies on his left side, and that kidney is always larger and fatter than the kidney on the right side. Oxen, like other domestic animals, differ in colour; but at the same time red appears to be the most com- mon, and the redder they are, the more they are esteemed. It is said, that Oxen of a bay colour last longest ; that those of a brown colour are sooner fa- tigued, and shorter lived ; that the grey, brindled, and white are not proper for work, and only fit to be fatted for slaughter. But whatever colour the coat of the ox is of, it should be shining, thick, and suf't to the touch ; for if it is rough and uneven, we have rea- son to think that the animal is not well, or at least, that he is not of a slrong constitution. The ox should only be worked from three years old to ten ; and it is proper then to take him from the plough, in order to fatten and sell him, as the flesh will be better than if he be kept longer. The age of this animal is known by his teeth and horns. The first front teeth fall out when he is ten months old. and are replaced by others which are larger and not so white. At sixteen months those on each side of the middle teeth drop out, and are replaced by others ; and at three years old all the the incisive teeth are re- newed. They are then all long, white, and even j and, in proportion as the ox advances in years, they decay, NATURAL HISTORY. 1?1 andbecome unequal and black. The borns fall off at three' years, and these are replaced by other horns, which, like' the second teeth, do not fall off a second time. Those of the ox and the cow grow larger and longer than those of the bull ; but the growth of 'these second horns is not uniform. The fourth year of the age of the ox, two little pointed horns sprout, which are even, and terminate at the head by a kind of knob. The fol- lowing year this knob grows from the head, pushed out by a cylinder of horn, which forms and terminates also by another knob ; for as long as the animal lives, the horns grow. These knobs become annular knobs, which are easily to be distinguished in the horns, and by which also the age may be easily known, by reck- oning three years for the first knob next the point of the horn, and one year more for each of the intervals between the other knobs. The horse eats night and day, slowly, but almost continually. The ox, on the contrary, eats quick, and takes in a short time all the food which he requires ; after which he ceases to eat, and lies down to ruminate. This difference arises from the different conformation of the stomachs ofthese animals. The ox, of whose sto- machs the two first form but one bag of a vast capacity, can in both of them receive grass, at the same time which it afterwards ruminates and digests at leisure. The horse, whose stomach is small, and can receive but a small quantity of grass, is filled successively inpropoi- tion as he digests it, and it passes into the intestines, where the principal decomposition of the food is performed. Chewing the cud is but a vomiting without straining, occasioned by the re-action of the first stomach on the food which it contains. The ox fills the two first stomachs, the paunch, and the bag, which is but a poj> 172 NATURAL HISTORY. tion of the paunch, as much as he can. This membrane acts with force on the grass which it contains; it is chewed but a little, and its quantity is greatly increas- ed by fermentation. Were the food liquid, this force of contraction would occasion it to pass by the third stomach, which only communicates with the other by a narrow conveyance, and cannot admit such dry food, Or, at least, can only admit the moister parts. The food must, therefore, necessarily pass up again into the oasophagus, the orifice of which is larger than the ori- fice of the conduit, and the animal again chews and macerates them, imbibes them afresh with its saliva, and thus by degrees makes the aliment more moist. He reduces it to a paste, liquid enough for it to enter this conduit which passes into the third stomach, where it is again macerated before it enters the fourth ; and it is in this last stomach that the decomposition of the hay is finished, which is reduced to a perfect mucilage. What chiefly confirms the truth of this explication is, that as long as the animals suck, and are fed with milk and other liquid aliments, they do not chew the cud. They chew the cud much more too in winter, when they are fed with dry food, than in summer, when they eat tender grass. Good milk is neither too thick nor too thin. Its consistence should be such that when we take a drop, it should preserve its roundness without running, and in colour it should be of a beautiful white. That which is inclinable to blue or yellow is not good. Its taste should be sweet, without any bitterness or sourness. It is better during the month of May, and during the summer, than in the winter ; and it is never perfectly good but when the cow is of a proper age, and in goecl NATURAL HISTORY. 173 health. The milk of young cows is too thick, that of old ones during the winter is also too thick. The milk of cows which are hot, is not good, any more than that of a cow which is near her time, or which has lately calved. In the third and fourth stomach of the calf which sucks, there are clots of curdled milk. These when dried in the air, serve to make runnet, or that well-known substance which coagulates milk. The longer the runnet is kept, the better it is, and it requires but a small quantity of it to make a great deal of cheese. Bulls, cows, and oxen, are apt to lick themselves, but mostly when they are quiet ; and as it is thought that it hinders them from fattening, it is usual to rub all the parts of their bodies they can touch with their dung. When this precaution is not taken, they raise up the hair of their coats with their tongues, which are very rough, and they swallow this hair in large quantities. As this substance cannot digest, it re- mains in the stomach, and forms round, smooth balls, which is sometimes of so considerable a size, as to prevent their digestion. These knobs in time get co- vered with a brown crust, which is somewhat hard. It is, notwithstanding, but a thick mucilage, which, by rubbing and co-action becomes hard and shining. It is never found any where but in the paunch, and it' any of the hair gets into the other stomachs, it does not remain, but seems to pass with the aliments. Animals which have incisive teeth, such as the horse and the ass, in both jaws, bite short grass more easily than those which want incisive teeth in the up- per jaw. Hence if the sheep and the goat bite the closest, it is because they are small, and their lips are tliin-. But the ox, whose lips are thick, can only bite 17-1 NATURAL HISTORY. long grass ; and it is for this reason that they do no harm to the pasture on which they live, as they can only bite off the tops of the young grass. They do not stir the roots, and for this reason scarcely hurt the growth ; instead of which, the sheep and the goat bite so close, that they destroy the stalk and spoil the root. Besides, the horse chooses the most delicate grass, and leaves the largest to grow, the stalks of which are hard. The ox, on the other hand, bites these thick stalks, and by little and little destroys the coarse grass ; so that, at the end of some years, the field on which the horse has lived becomes a very bad one, whilst that on which the ox has broused, becomes fine pasture. NATURAL HISTORY. THE RAM. THE EWE. We can no longer doubt, but that animals which are actually domestic, were formerly wild. But man, who has conquered so many millions of individuals, can he boast of having conquered an entire species > As they were all created without his aid, may he not 176 NATURAL HISTORY. also believe, that they have had orders to grow with- out his help ? If we consider, nevertheless, the weak- ness and stupidity of the sheep, and at the same time reflect, that this animal, without defence, cannot rind safety in flight ; that he has for his enemies all de- vouring animals, which seem to seek him in preference to any other; that formerly this species produced but few ; that each individual lived but a short time ; we shall be inclined to think, that from the beginning, sheep were entrusted to the care of man. What seems to give farther strength to this opinion is, that there are no wild sheep in the deserts ; that in all places where man does not rule, the lion, the- tiger, and the wolf reign by force, and by cruelty ; and these animals of blood and carnage, all live longer, and multiply much more than sheep ; and, in short, that if we were now to abandon the troops of these species, which we have rendered so numerous, they would soon be destroyed before our eyes, and the species would be entirely an- nihilated by the voraciousness of its numberless spe- cies of enemies. The sheep is indeed absolutely without resource, and without defence. The ram has but feeble arms ; his courage is nothing but a petulence useless to him- self, inconvenient to others, and which is destroyed by castration. The weather sheep are still more fearful than ewes ; it is through fear that they muster up so often in troops. The smallest noise to which they are unaccustomed, is sufficient to make them fly, and get close together. This fear is attended with the greatest stupidity ; for they know not how to fly the danger, nor do they even seem to feel the inconveni- ence of their situation. They continue wherever they are, either in rain or snow, whence they will not stir ; NATURAL HISTORY. 177 and to oblige them to change their situation, they must have a chief, who is intrusted to walk first, and whom they will follow step by step. This chief will remain with the rest of the flock, without motion, in the same place, if he were not driven from it by the shepherd, or the dog which guards them, who, in fact, watches for their safety, defends, directs, and sepa- rates them, assembles them together, and communi- cates to them motions not their own. Goats, which in mcny things resemble sheep, have much more understanding. But this animal, so cowardly in itself, so destitute in sentiment, is the most precious and the most useful of animals, both for the present and future support of man. Of itself, it not' only supplies our greatest ne- cessities, but, at the same time furnishes us both with food and clothing. Without enumerating the parti- cular advantages we have from the milk ; the skin, and even the bowels, the bones, and the dung of this animal evince that nature has given it nothing but what is useful to man. These simple animals, are also of a very weak con- stitution; for they cannot walk long; travelling weak- ens and exhausts them ; and when they run, they pant, and are soon out of breath. The great heat of the sun is as disagreeable to them, as too much mois- ture, cold and snow. They are subject to many dis- orders the greatest part of which are contagious ; too much fat sometimes kills them, and always p'revents thorn from having young ones. They suffer a great deal in having young, have frequent abortions, and require more care than any other domestic animal. At one year old, the sheep lose the two front teeth of the lower jaw ; and almost every one knows that they VoL I. Y 178 NATURAL HISTORY. have no incisive teeth in the upper jaw. At eighteen months old, the two neighbouring teeth t)f the two first that fell, fall also ; and, at three years old, they arc replaced. They are then even, and tolerably whits ; but, in proportion as the animal becomes older, they become uneven and black. The age of the ram i* also known by his horns, which shew themselves in the first year, and frequently from the birth. They grow every year a ring, which is a mark round. The sheep have generally no horns ; but they have bony prominences on their heads, in the same part where the horns of the rams grow ; there are, notwithstand- ing, some sheep which have two, and even four horns. These sheep are like the others ; their horns are five or six inches long, but less turned than those of the ram ; and when there arc four horns, the two exterior ones are shorter than the two others. Sheep carry their young five months, and drop them at the beginning of the sixth. They usually produce but one lamb, and sometimes two. In warm climates they may produce twice a year, but in cold elimates they produce but once a year. The sheep has great plenty of milk for five or sir months. This milk is tolerable food for children, and for poor people in the country ; and they make good cheese with it, especially when it is mixed with cow's milk. In dry soils, and in high grounds, where wild thyme and other odoriferous herbs abound, the flesh of the sheep is of a much better quality than when it is fed in low plains and humid vallies, unless these plains are sandy and near the sea ; for then all the herbs imbibe a saltness, and the flesh of mutton is no where so good as in these salt meadows. The sheep's milk NATURAL HISTORY 179 is also more abundant, and of a better flavour, as no- thing is more pleasing to the taste of these animals than salt, nothing is more salutary for them, when it is given them in moderation ; and in some places, they put into the sheep-pen a bag of salt, or a salt stone, which they will lick by turns. Nothing contributes more to fatten sheep, than to give them water in great quantity ; and nothing pre- vents this advantage so much as the heat of the sun. We frequently find worms in the livers of animals ; and in the Journal des Savans, there is a description of worms found in the livers of sheep and oxen, as also in the German Ephcmerides. One would think that these singular worms were only found in the livers of animals which chew the cud ; but Mr Daubenton has found some, which exactly resemble them, in the liver of the ass ; and it is probable that they may be found in the livers of other animals. It has also been said, that butterflies have been found in the livers of sheep. The operation of sheep-shearing is performed once a year. In France it is performed in the month of May, after the sheep have been well washed, in order to make the wool as clean as possible. In April it would be too cold ; and if they were to wait till the months of June and July, there would not be time enough for the wool to grow during the summer, to preserve them from the cold in the winter. The wool of ewes is generally better, and in greater abun- dance than that of rams. That on the neck, and the top of the back, is the best. White wool is preferable to grey, brown, or black, because in dieing it will take any colour. For the quality, that which is. smooth is better than that which is frizzled ; it is also said, thut li 0 NATURAL HISTORY. s' e -i whose wool is frizzled are not so healthy others. Anotl er considerable advantage may be made of sheep, by inclosing them on the ground we wish to improve. The dung, the urine, and the heat of the bodies of these animals, will, in a little time, enrich the most exhausted, cold, and infertile ground. A hun- dred sheep, in one summer, will enrich eight acres of land for six years. The ancients have said, that all animals which chew the cud have tallow ; but this is only true of the sheep and the goat ; and that of the goat is more abundant, whiter, drier, firmer, and of a better quality than any other. It is for the most part about the loins that this suet is amassed in the greatest quantities, and the left loin has always a larger quantity than the right. Sheep have no other fat about them but suet ; and this matter is so predominant in their habit, that all the extremities of the body are edged with it ; even the blood contains a considerable quantity. The wool of Italy, Spain, and England, is finer than that of France. Those animals with large, long tails, which are so common in Africa and Asia, and to which travellers have given the name of Barbary sheep, appear to be of a different species from our sheep, as well as the lamb of America. NATURAL HISTORY. 181 THE GOAT. THOUGH the species of animals are separated from tach other ; yet some species approach so near to others, that space is only left for a bare line of distinc- tion. The ass might almost replace the horse ; and, if the species of sheep were to fail, that of the goat might supply the loss. The goat, like the sheep, affords both milk and suet in considerable quantities. Her hair, though rougher than wool, serves, however, to make very good stuffs ; and her skin is worth more than the skin of the sheep. The flesh of the young goat also nearly resembles that of the lamb. These auxiliary species are wilder and more robust than the principal species. The ass and the goat do not require so much care as the horse and the sheep ; for they every where find food to support them, and browse equally on plants of all kinds. They are less affected with the intemperance of the climate, and can do better without the help of man. The less depend- ence they have on us, the more they seem to belong to nature. 182 NATURAL HISTORY. Although the goat is a distinct species, yet he will couple with the sheep ; but no intermediate species has been introduced between the goat and the sheep. These two species are distinct, remaining constantly separated, and always at the same distance from each other, and have never been changed by this mixture, or produced any new stock or new breed of interme- diate animals. They have, at most, only produced different individuals, which have no influence on the unity of each primitive species, and which, on the contrary, confirms the truth of their different charac- teristics. The goat has naturally more understanding, and can shift better for herself than the sheep. She comes voluntarily, and is easily familiarized: she is sensible of caresses, and capable of attachment : she is also stronger, lighter, more agile, and less timid than the sheep : she is lively, capricious, and lascivious. Goats are fond of straying in solitary places, of climbing up steep places, of sleeping on the tops of rocks, and on the brink of precipices. The inconstancy of this animal's nature is shewn by the irregularity of her actions ; she walks, stops short, runs, jumps, advances, retreats, shews, then hides her- self, or flies, and this all from caprice, or without any other determinate cause than her whimsical vivacity. All the suppleness of the organs, all the nerves of the body, are scarcely sufficient for the petulance and ra- pidity of these motions, which are all natural to her. That these animals are naturally fond of mankind, and that in uninhabited places they do not become wild, the following anecdote is a striking confirmation. In 1698, an English vessel having put into harbour at the isle of Bonavista, two negroes presented them- NATURAL HISTORY. 183 selves on board, and offered the English as many goats as they choose to take. At the surprise which the captain shewed at this offer, the negroes observed there were but twelve persons in the island ; that the goats multiplied so fast, that they became troublesome ; and that, far from having any trouble in taking them, they followed them with a kind of obstinacy, like do- mestic animals. Goats go five months with young, and bring forth at the beginning of the sixth month. They suckle the young ones for about a month or five weeks ; so that it may be reckoned about six-and-twenty weeks from the time of their coupling till the time that the young kid begins to eat. The goat generally produces one kid, sometimes two, very rarely three, and never more than four ; and she brings forth young, from a year or eighteen months, to seven years. The knobs in the horns, and their teeth, ascertain their age. The num- ber of teeth is not alwavs the same in female goats ; but they have generally fewer than the male goat, which has also the hair rougher, and the beard and the horns longer. These animals, like oxen and sheep, have four stomachs, and chew the cud. This species is more diffused than that of the sheep ; goats like ours are found in several parts of the world, only in Guinea, and other warm countries they are smal- ler ; but in Muscovy, and other cold climates, they are larger. The goats of Angora, and of Syria, have ears hanging clown, and are of the same species with ours, They mix and produce together, even in our climate, The males have horns almost as long as the common goat ; but the circumference and directions are very different. They are extended horizontally on each side of the head, and form spirals, somewhat like a 184 NATURAL HISTORY. worm. The horns of the female are short, and first turn round backwards, then bend down, and turn round before, so much, that they end near the eyes ; and in some their circumference and direction vary. The male and female goat of Angora, which I have setn, are such as I have described ; and these goats, like all the animals of Syria, have the hair so very long, and thick, and fine, that stuffs have been made of it, almost as handsome and glossy as our silks. It is, in fact, what is commonly termed mohair. THE HOG. I shall treat of the sow, the hog of Siam, and the wild boar, at the same time, because they form all three but one and the same species ; one is wild, and the other two are domestic. Aristotle first divided quadrupeds into beasts with the hoof entire, those with cloven feet, and the species which have claws. He allows that the hog is of an ambiguous nature ; but the only reason he gives, is NATURAL HISTORY. 18$ that in Illyria swine are found which have hoofs, and in some other parts a species which have claws. This animal is also a kind of exception to the two general rules of nature, viz. That the larger animals are, the fewer young they produce at a birth ; and that of all animals, those which have claws are the most prolific. The hog, though in its make greatly above the mid- dle size, produces more than any such animal, or in- deed, than any other quadruped. To the singularities we have already related, we shall add another, which is, that the fat of the hog is different from that of almost all other quadrupeds, not only in its consistence and quality, but also in its position in the body of the animal. The fat of" man, and of animals which have no tallow such as the dog, the horse, &c. is mixed pretty equally with the flesh. The tallow in the ram, the goat, the stag, &c. is found only in the extremities of it. The fat covers the flesh, and forms a thick, distinct, and continued bed or layer, between the flesh and the skin. The hog has this in common with the whale, and o- ther cetaceous animals, the fat of which is only a kind of lard, nearly of the same consistence with, but more oily than that of the hog. This lard in ceta- ceous animals also forms beneath the skin a bed of many inches in thickness, which envelopes the flesh. There are only the hog, and two or three other species of animals, which have defensive or very long canine teeth. They differ from the other teeth, by 'coming out at the front, and growing during their whole lives. In the elephant and sea-cow, they are cylindrical, and some feet long. In the wild-boar and male hog, they are partly bent in form of a cir- de ; and I have seen them from nine to ten inches in Vol. I. Z 186 NATURAL HISTORY. length. They are not very deep in the socket, and have also, like those of the elephant, a cavity at the superior extremity ; but- the elephant and sea-cow have only these defensive teeth in the superior jaw, and even want canine teeth in the inferior jaw. The male hog and the wild boar on the other hand, have them in both jaws, and those of the inferior are the most useful to this animal. These are also the most dangerous ; for it is with these lower tusks the wild boar wounds. Of all quadrupeds the hog appears the most rough and unpolished. His voraciousness seems to be owing to the incessant avidity he has to fill the vast capaci- ousness of his stomach. It is the roughness of the hair, the hardness of the skin, and the thickness of the fat, which render these animals so insensible to blows. Mice have been known to lodge in their backs, and eat their fat and their skin, without their seeming sensible of it. Their other senses are good ; and the huntsmen know that wild boars both see, hear and smell at a great distance. In order therefore to surprise them, they wait in silence during the night, and place themselves under the wind, to prevent the boars perceiving their smell, of which they are sensi- ble at a great distance, and which makes them change their road immediately. This imperfection in the senses of the taste and touch, is still more increased by a distemper which is called the measles, and which renders them almost absolutely insensible. This disorder proceeds in ge* neral from the coarseness of their food ; for the wild boar, which usually lives on corn, fruits, acorns, and roots, is not subject to this distemper, any more than the young pig whilst it sucks. This is only to he NATURAL HISTORY. 187 prevented by keeping the domestic hog in a clean stable, and giving him plenty of wholesome food. By these means his flesh will become excellent to the taste, and the lard firm and brittle, if he be kept for a fortnight or three weeks before he is killed* in a clean stable without litter, and get no food but dry corn. For this purpose we should choose a sow of a- bout a year old, full of flesh and fat. The Wild Boar is hunted by dogs, or else taken by surprise in the night by the light of the moon. As he runs but slowly, leaves a strong odour behind him, defends himself against the dogs, and wounds them dangerously, he should not be hunted by dogs design- ed for the stag and the goat. The oldest only should be attacked, and these are easily known by their traces. A young wild boar, of three years old, is difficult to take, because he runs a great way without stopping. A wild boar that is older, on the other hand, does not run far, suffers himself to be closely hunted, and is not much afraid of the dogs. In the day he usually hides himself in the thickest and most unfrequented parts of the wood, and in the evening and at night he goes out in quest of food. In summer, when the corn is ripe, it is easy to surprise him, particularly among oats, where he frequents every night. As soon as he is killed, the huntsmen immediately cut out the. tes- ticles, the smell of which is so strong, that if five or six hours were to elapse without cutting them out, all the flesh would be infected. In an old wild boar the head only is good to eat ; but the flesh of the young wild boar is extremely delicate. Nobody is ignorant of the profits arising from the hog. His flesh sells for more than that of the ox, the the lard for double, the blood, the bowels, the viscera, 188 NATURAL HISTORY. the fed, and the tongue, when properly prepared, may all be eaten. The dung of the hog is much colder than that of other animals, and should not be used for any but hot and dry lands. The skin hath its use, for sieves are made of it ; and brooms, brushes, and pen- ciMbrushes, are made of the hair. The flesh of this animal takes salt and salt-petrc better than any other, and will keep longer salted. This species, though abundant, and greatly spread in Europe, in Africa, and in Asia, was not, however, found on the Continent of the new world : they were transported by the Spaniards, who have carried black hogs to the Continent, and to almost all the large is- lands of America. They are multiplied and become wild in many places ; and resemble our wild boars, •with this difference, however, that the body is shorter, the head larger, and the skin thicker. Domestic hogs in warm climates are all black like wild boars. The Hog of Siam resembles the wild boar more than the common hog. One of the most evident signs of degeneration is the ears, which become much more supple when the animal changes into the domestic state : in short, those of the domestic hog are not near so stiff, are much longer, and more pendant, than those of the wild boar, which should be regarded as the* model of the species.

THE POINTER. .I HE largeness of the make, the elegance of the form, the strength of the body, the freedom of the mo- tions, and all the exterior qualities, are not the noblest properties of an animated being. As in mankind, understanding is preferred to figure, courage to strength NATURAL HISTORY. 191 and sentiment to beauty ; so the interior qualities are those which we esteem most in animals. It is in these that they differ from the automaton, it is by these they are raised above the vegetable, and made to ap- proach nearer to ourselves. It is their sense which ennobles their being, which regulates, which enlivens it, which commands the organs, makes the members active, gives birth to desire, and gives to matter pro- gressive motion, will, and life. The dog, independently of his beauty, vivacity, strength, and swiftness, has all the interior qualities which can attract the regard of man. The tame dog comes crawling to lay at his master's feet his courage, strength, and talents, and waits his orders to use them. He consults, he interrogates, and he beseeches. The glance of his eye is sufficient ; he understands the signs of his will. Without the vices of man, he has all the ardour of sentiment, and, what is more, he has fidelity and constancy in his affections. He has no ambition, no interest, no desire of revenge, no fear but that of displeasing his master. He is all zeal, all warmth, and all obedience. More sensible to the re- membrance of benefits than of wrongs, he soon forgets, or only remembers them to make his attachment the stronger. Far from running away, he licks the hand which is the cause of his pain, he only opposes it by his cries, and at length entirely disarms it by his pa- tience and submission. More docile and flexible than any other animal, the dog is not only instructed in a short time, hut he even conforms himself to the motions, manners, and habits of those who command him. He has all the man- ners of the house where he inhabits. Like the other domestics, he is always attentive to his master ; and, li)2 NATURAL HISTORY. striving to anticipate the wants of his friends, he gives no attention to indifferent people. When the care of the house is intrusted to him during the night, he be- comes sometimes ferocious. He watches, he walks his rounds, he scents strangers afar off; and if they happen to stop, or attempt to break in, he flies to op- pose them, and by reiterated barkings, efforts, and cries of passion, he gives the alarm. As furious against men of prey as against devouring animals, he flies upen, wounds, and tears them, and takes from them what they were endeavouring to steal ; but, content with having conquered, he rests himself on the spoils, will not touch it even to satisfy his appetite, and at once gives an example of courage, temperance, and fidelity. Thus we may see of what importance this species is in the order of nature. Without the assistance of the dog, how could man have been able to tame, and reduce into slavery, other animals ? How could he have discovered, hunted, and destroyed, wild and ob- noxious creatures ? To keep himself in safety, and to render himself master of the living universe, it was necessary to begin by making himself friends among animals, in order to oppose them to others. The first art, then, of mankind, was the education of dogs, and the fruit of this art was the conquest and peaceable possession of the earth. The dog, faithful to man, Avill always preserve a portion of empire, and a degree of superiority over o- ther animals. He commands them, and reigns him- self at live head of a flock, where he makes himself better understood than the voice of the shepherd. Safety, order, and discipline are the fruits of his vigi- lance and activity. But it is above all in war against NATURAL HISTORY. 103 ihose animals which are his enemies, or which are in- dependent, that his courage shines forth, that his un- derstanding is displayed, and that his natural and ac- quired talents are united. As soon as the sound of the horn, or the voice of the huntsman, has given the signal of an approaching war, transported with fresh ardour, the dog expresses his joy, and shews by his motions, and cries of impatience, his desire to combat and to conquer. Then,, in silence, he investigates the traces of his enemy, and, by different cries, indicates the time, the distance, the species, and even the age of his prey. In deserts and depopulated countries, there are wild dogs, which in their manner differ only from wolves by the facility with which they are tamed. They unite also in large troops, to hunt and attack by force wild boars and bulls, and even lions and ticers. In O America, the wild dogs spring from a breed anciently domestic, having been transported from Europe ; and having been either forgotten or abandoned in these deserts, are multiplied to such a degree that they go in troops to inhabited places, where they attack the cattle, and sometimes even insult the inhabitants. They are then obliged to drive them away by force, and to kill them like other ferocious animals ; and in fact, dogs are such till they become acquainted with man. When, however, we approach them with gen- tleness, they soon become familiar, and remain faith- fully attached to their masters. The wolf, on the other hand, although taken young, and bred in the house, is only gentle in his youth, for he never loses his desire for prey, and sooner or later he gives himself up to his fondness for rapine and destruction. Vol I. A a 194 . NATURAL HISTORY. The dog is the only animal whose fidelity may be put to the proof. He is the only one which always knows his master and his friends : the only one which perceives the approach of a stranger: the only animal, in short, whose talents are evident, and whose educa- tion is always good. Of all animals, the dog has fin understanding mo?t susceptible of impressions, and is most easily taught by moral causes. He is also, above all other creatures, most subject to the variety and other alterations oc- casioned by physical influences. The temperament, the faculties, and habits of do<^> vary prodigiously, and their form is not uniform. In the same country, one dog is very different from another dog, and the species is quite different in itself in different climates. But what is most difficult to ascertain in the nu- merous variety of different races, is the character of the primitive and original breed. How are we to know the effects produced by the influence of the cli- mate, food, &c. ? Among domestic animals, the dog is, above all others, that which is most attached to man. He is that in which sentiment predominates enough to ren- der him docile, obedient, and susceptible of all impres- sions, and even of all constraint. It is not astonish- ing, therefore, that of all animals tin's should also be that in which we find the greatest variety, not only in figure, in height, and in colour, but in every other • quality. There are also some circumstances which concur to this change. The dog in general lives but a short time; it produces frequently, and in pretty large num- bers ; and as it is perpetually beneath the eyes of mart, as soon as by a chance usual to nature, there may have NATURAL HISTORY. 195 Lcen found among pome individuals, singularities, or apparent varieties, endeavours may have been used in order to perpetuate them, by uniting together these singular individuals, as we do at present, when we wish to procure new breeds of dogs, and other animals. Dogs which have been abandoned in the deserts of America, and have lived wild for a hundred and fifty, or two hundred years, though changed from their ori- ginal breed when they are sprung of the domestic dogs, have notwithstanding this long space of time retained, at least in part, their primitive form, and travellers re- port that they resemble our greyhound : these wild dogs, however, are extremely thin and light* and as the greyhound does not differ much from the cur, or from the dog which we call the shepherd's dog, it is natural to think, that these wild dogs are rather of this species, than real greyhounds. Ancient travellers inform us, that the dogs of Canada have the ears straight h'ke foxes, and resemble the middle-sized mastiff, that is, our shepherd's dog, and that those of the deserts of the Aratilles isles, had also the head and ears very long, and are very like foxes. Besides what we learn from the narratives of travellers, we find that
