    the different species of the latter. All the viviparous animals, according to him, have teeth, but not always an equal number in each jaw. In horned animals, the anterior upper teeth are wanting, which arrangement is also to be found in some animals without horns, as the camel. Some animals are furnished with tusks, (des dents saillantes) en dehors as the boar; in some, as the lion, panther, dog, &c, they resemble the teeth of a saw, in others, the surfaces are flat, as in the horse, ox, &c. No animals have at the same time tusks and horns, and those which have their teeth arranged like the teeth of a saw, have neither tusks nor horns. The front teeth are generally more pointed than those in the posterior part of the jaw ; the teeth of the seal, how- ever, are all pointed as if to indicate that this animal formed the connecting link between quadrupeds and fishes. No animals, he says, have a double range of teeth in the same jaw, although Ctesias would have us believe that there exists in India an animal called Martichore, which has a triple range. Aristotle considered the tusks of the elephant positively as teeth. He said, also, that the anterior teeth, only in man, were shed ; that the molares were never changed in any known ani- mal ; that none of the teeth of the hog were shed ; that the age of many animals is indicated by their teeth, which assume a blackish color as the animal grows old; he mentions the teeth of the horse, however, as an exception to this general rule, as they become, on the contrary, white with age. That animals with pointed teeth, have, generally, a very large mouth. Aristotle believes, with Hippocrates, that those animals which have a great number of teeth, live longer than those which have them in small numbers, and separated. He remarked, also, that men have more teeth than women ; which arrangement, he said, is found to exist in the females of some animals, as the sheep, the she-goat, and the sow. It is difficult to conceive how an error like this could have been advanced by such an anatomist as Aristotle, and we are forced to conclude, either that his text, has been altered, or that he was, as some authors have thought, merely the historian of the anatomical discoveries of his time, and had never himself, made dissections. He considered the beaks of birds as representatives of their 2
