The Chimpanzee has a long palate, like the other great Apes of the West African woods. Moreover, it has a uvula in the back of the throat, and the back of the tongue is marked with great papillæ, which take up the shape of a T. It does not do more than grunt “hem,” and bark after a fashion; and the use of some great air-pouches, which resemble those of the Gorilla, are therefore not very apparent. But the bony structures of the palate are interesting, for at the back of it they do not form a simple knob, as in the Gorilla, but resemble those of man, and there is a little prominence, with a festoon curve on each side. It lives upon vegetable food, and its teeth are admirably suited for it; they are of the same number as those of the rest of the great man-shaped Apes, and do not differ very much from them. The front teeth are large, and project, and do not bite very up and down on the tips, so they wear behind quicker than in front, their general shape being rather peculiar and distinctive. Female Chimpanzees have smaller eye-teeth than the males, and all have them with a sharp edge behind, so that they can cut a pine-apple as well as pierce it. Behind them are the pre-and true molars, but the last tooth of the upper jaw looks small, for its hinder projections or cusps are small. In the lower jaw the last tooth has a fifth cusp, but it is smaller proportionately than in the lower Monkeys; and the first pre-molar has its front and outer angle stuck out very much after the fashion of the Baboons. Now these are little matters, which do not appear to have anything to do with causes and effects, the adaptation of means to ends, or which do not enable the creature to chew and crush its food a bit the less well, or better than others; they refer to some hidden mystery which unites apparently very different animals together in the scheme of creation. Thus the Chimpanzee has human-like, Gorilla-like, Baboon-like, and other Monkey-like peculiarities, so far as the teeth are concerned, and yet which do not interfere with the successful mastication of the food. We may make theories about them of supreme interest, which may explain why animals are alike and unlike, and how the structures of superior animals were foreshadowed in those of lower ones, and the structures of the latter in those of still simpler forms of life. It is the great front teeth, the large space hidden by the visible nose, the prominent upper, and the great length of the lower jaw, which give such a Baboon-like appearance to the face of the Chimpanzee’s skull; and this is interesting, for there may have been a kinship between the two tribes.
