Travellers inform us that the large apes of the southern parts of Asia produce bezoars in their stomachs, which are superior to those of the goats and gazelles. These large apes are the ouanderou and the douc; to them, therefore, we must refer the production of the bezoar. It is pretended that the bezoars of the ape are always round, whereas the other bezoars are of different figures. _Distinctive Characters of this Species._ The douc has no callosities on his posteriors, and is cloathed all over with hair: his tail is not so long as his body and head: his face is covered with a reddish down: the ears are naked, and of the same colour as the face: the lips are brown, as are the orbits of the eyes. The colour of the hair is very bright and variegated: he has a purple coloured collar round his neck: his forehead, body, arms, and legs, are white, and on the chin is a kind of yellow beard: he is black on the top of the forehead and the upper part of the arms: the parts below the body are of an ash colour: the tail, and under parts of the loins, are white: he as often walks on two feet as on four: he is three feet and a half, or four feet, high when he is upright. I do not know whether the females in this species be subject to the periodical emanation. CONCLUSION OF THE APES OF THE OLD CONTINENT. THE SAPAJOUS AND THE SAGOINS. We shall now pass from one continent to the other; all the four-handed animals which we have described, and which we comprehended under the generic names of Apes, Baboons, and Monkeys, belong exclusively to the Old Continent; and all those which remain to be spoken of are only to be found in the New World. We shall first distinguish them by the two generic names of Sapajous and Sagoins. Both these animals have their feet nearly like those of the apes, baboons, and monkeys; but they differ from the apes by having tails, and from the baboons and monkeys by not having a pouch in each cheek, nor callosities on their posteriors; in short, they differ from the apes, baboons, and monkeys, by having a broad division between their nostrils, and the apertures being on the sides and not under the nose; therefore the sapajous and sagoins are not only specifically, but even generically different from the apes, monkeys, and baboons. When compared together they are also found to differ in some generic characters, for every sapajou has a long tail, which he can make use of to seize or lay hold of any object. This tail they bend, extend, and curl at pleasure, and by the extremity of which they suspend themselves from the branches of trees to reach whatever they want: the under part of this tail is commonly without hair, and covered with a smooth skin. The tails of the sagoins, on the contrary, are proportionably longer than those of the sapajous, and are weak, straight, and entirely covered with hair, so that they cannot make use of them either to lay hold of any object, or for the purpose of suspending themselves.
