that no instance can be produced, of her having permitted any one race of her animals to become extinct; of her having formed any link in her great work so weak as to be broken. To add to this, the traditionary testimony of the Indians, that this animal still exists in the northern and western parts of America, would be adding the light of a taper to that of the meridian sun. Those parts still remain in their aboriginal state, unexplored and undisturbed by us, or by others for us. He may as well exist there now, as he did formerly where we find his bones. If he be a carnivorous animal, as some anatomists have conjectured, and the Indians affirm, his early retirement may be accounted for from the general destruction of the wild game by the Indians, which commences in the first instant of their connection with us, for the purpose of purchasing match-coats, hatchets, and firelocks, with their skins. There remain then the buffalo, red deer, fallow deer, wolf, roe, glutton, wild cat, monax, bison, hedgehog, marten, and water-rat, of the comparative sizes of which we have not sufficient testimony. It does not appear that Messieurs de Buffon and D'Aubenton have measured, weighed, or seen those of America. It is said of some of them, by some travellers, that they are smaller than the European. But who were these travellers? Have they not been men of a very different description from those who have laid open to us the other three quarters of the world? Was natural history the object of their travels? Did they measure or weigh the animals they speak of? or did they not judge of them by sight, or perhaps even from report only? Were they acquainted with the animals of their own country, with which they undertake to compare them? Have they not been so ignorant as often to mistake the species? A true answer to these questions would probably lighten their authority, so as to render it insufficient for the foundation of an hypothesis. How unripe we yet are, for an accurate comparison of the animals of the two countries, will appear from the work of Monsieur de Buffon. The ideas we should have formed of the sizes of some animals, from the information he had received at his first publications concerning them, are very different from what his subsequent communications give us. And indeed his candor in this can never be too much praised. One sentence of his book must do him immortal honor. "J'aime autant une personne qui me releve d'une erreur, qu'une autre qui m'apprend une verité, parce qu'en effet une erreur corrigée est une verité."[19] He seems to have thought the cabiai he first examined wanted little of its full growth. "Il n'etoit pas encore tout-a-fait adulte."[20] Yet he weighed but forty-six and a half pounds, and he found afterwards,[21] that these animals, when full grown, weigh one hundred pounds. He had supposed, from the examination of a jaguar,[22] said to be two years old, which weighed but sixteen
