question is of moment in tracing the history of man, I purpose to contribute my mite. And, in order to admit all the light possible, a view of brute animals as divided into different races or kinds, will make a proper introduction.

      As many animals contribute to our well-being, and as many are noxious, man would be a being not a little imperfect, were he provided with no means but experience for distinguishing the one sort from the other. Did every animal make a species by itself (indulging the expression) differing from all others, a man would finish his course without acquiring<4> as much knowledge of animals as is necessary even for self-preservation: he would be absolutely at a loss with respect to unknown individuals. The Deity has left none of his works imperfect. Animals are formed of different kinds; resemblance prevailing among animals of the same kind, dissimilitude among animals of different kinds. And, to prevent confusion, kinds are distinguished externally by figure, air, manner, so clearly as not to escape even a child.* Nor does Divine Wisdom stop here: to complete the system, we are endued with an innate conviction, that each kind has properties peculiar to itself; and that these properties belong to every individual of the kind(a). Our road to the knowledge of animals is thus wonderfully shortened: the experi-<5>ence we have of the disposition and properties of any animal, is applied without hesitation to every one of the kind. By that conviction, a child, familiar with one dog, is fond of others that resemble it: An European, upon the first sight of a cow in Africa, strokes it as gentle and innocent: and an African avoids a tiger in Hindostan as at home.

      If the foregoing theory be well founded, neither experience nor argument is required to prove, that a horse is not an ass, or that a monkey is not a man(b). In some individuals indeed, there is such a mixture of resemblance and dissimilitude, as to render it uncertain to what species they belong. But such instances are rare, and impinge not on the general law.2 Such questions may be curious, but they are of little use.

      Whether man be provided by nature with a faculty to distinguish innocent animals from what are noxious, seems not a clear point: such a faculty may be thought unnecessary to man, being supplied by reason and experience. But as reason and<6> experience have little influence on brute animals, they undoubtedly possess that faculty.*3 A beast of prey would be ill fitted for its station, if nature did not teach it what creatures to attack, what to avoid. A rabbit is the prey of the ferret. Present a rabbit, even dead, to a young ferret that never had seen a rabbit: it throws itself upon the body, and bites it with fury. A hound has the same faculty with respect to a hare; and most dogs have it. Unless directed by nature, innocent animals would not know their enemy till they were in its clutches. A hare flies with precipitation from the first dog it ever saw; and a chicken, upon the sight of a kite, cowers under its dam. Social animals, without scruple, connect with their<7> own kind, and as readily avoid others.* Birds are not afraid of quadrupeds; not even of a cat, till they are taught by experience that a cat is their enemy. They appear to be as little afraid of a man naturally; and upon that account are far from being shy when left unmolested. In the uninhabited island of Visia Grandé, one of the Philippines, Kempfer says, that birds may be taken with the hand. Hawks, in some of the South-sea islands, are equally tame. At Port Egmont in the Falkland islands, geese, far from being shy, may be knocked down with a stick. The birds that inhabit certain rocks hanging over the sea, in the island of Annabon, take food readily out of a man’s hand. In Arabia Felix, foxes and apes show no fear of man; the inhabitants of hot countries having no notion of hunting. In the uninhabited island Bering, adjacent to<8> Kamskatka, foxes are so little shy that they scarce go out of a man’s way. Doth not this observation suggest a final cause? A partridge, a plover, a pheasant, would be lost to man for food, were they naturally as much afraid of him as of a hawk or a kite.

      The division of animals into different kinds, serves another purpose, no less important than those mentioned; which is, to fit them for different climates. We learn from experience, that no animal nor vegetable is equally fitted for every climate; and from experience we also learn, that there is no animal nor vegetable but what is fitted for some climate, where it grows to perfection. Even in the torrid zone, plants of a cold climate are found upon mountains where plants of a hot climate will not grow; and the height of a mountain may be determined with tolerable precision from the plants it produces. Wheat is not an indigenous plant in Britain: no farmer is ignorant that foreign seed is requisite to preserve the plant in vigour. To prevent flax from degenerating in Scotland and Ireland, great quantities of foreign seed are annually imported. A ca-<9>mel is peculiarly fitted for the burning sands of Arabia; and Lapland would be uninhabitable but for rain-deer, an animal so entirely fitted for piercing cold, that it cannot subsist even in a temperate climate. Arabian and Barbary horses degenerate in Britain; and, to preserve the breed in some degree of perfection, frequent supplies from their original climate are requisite. Spanish horses degenerate in Mexico; but improve in Chili, having more vigour and swiftness there, than even the Andalusian race, whose off-spring they are. Our dunghill fowl, imported originally from a warm country in Asia, are not hardened, even after many centuries, to bear the cold of this country like birds originally native: the hen lays few or no eggs in winter, unless in a house warmed with fire. The deserts of Zaara and Biledulgerid in Africa, may be properly termed the native country of lions: there they are nine feet long and five feet high. Lions in the south of Africa toward the Cape of Good Hope, are but five feet and a half long, and three and a half high. A breed of lions transplanted from the latter to the former, would rise to the full size; and<10> sink to the smaller size, if transplanted from the former to the latter.*

      To preserve the different kinds or species of animals entire, as far as necessary, Providence is careful to prevent a mixed breed. Few animals of different species copulate together. Some may be brought to copulate, but without effect; and some produce a mongrel, a mule for example, which seldom procreates, if at all. In<11> some few instances, where a mixture of species is harmless, procreation goes on without limitation. All the different species of the dog-kind copulate together; and the mongrels produced generate others without end.4

      M. Buffon, in his natural history, borrows from Ray(a) a very artificial rule for ascertaining the different species of animals: “Any two animals that can procreate together, and whose issue can also procreate, are of the same species”(b). A horse and an ass can procreate together; but they are not, says he, of the same species, because their issue, a mule, cannot procreate. He applies that rule to man; holding all men to be of the same species, because a man and a woman, however different in size, in shape, in complexion, can procreate together without end. And by the same rule he holds all dogs to be of the same species. With respect to other animals, the author should peaceably be indulged in his fancy; but as it com-<12>prehends also man, I cannot pass it without examination. Providence, to prevent confusion, hath in many instances withheld from animals of different species a power of procreating together: but as our author has not attempted to prove that such restraint is universal without a single exception, his rule is evidently a petitio principii. Why may not two animals different in species produce a mixed breed? M. Buffon must say, that it is contrary to a law of nature. But has he given any evidence of this supposed law of nature? On the contrary, he proves it by various instances not to be a law of nature. He admits the sheep and the goat to be of different species; and yet we have his authority for affirming, that a he-goat and a ewe produce a mixed breed which generate for ever(c). The camel and the dromedary, though nearly related, are however no less distinct than the horse and the ass. The dromedary is less than the camel, more slender, and remarkably more swift of foot: it has but one bunch on its back, the camel has two: the race is more nu-<13>merous than that of the camel, and more widely spread. One would not desire distinguishing marks more satisfying; and yet these two species propagate together, no less freely than the different races of men and of dogs. M. Buffon indeed, with respect to the camel and dromedary, endeavours to save his credit by a distinction without a difference. “They are,” says he, “one species; but their races are different, and have been so past all memory”(a). Is not this the same with saying that the camel and the dromedary are different species of the same genus? which also holds true of the different species of men and of dogs. If our author will permit me to carry back to the creation the camel and the dromedary as two distinct races, I desire no other concession. He admits no fewer than ten kinds of goats, visibly distinguishable,
