One peculiar habit of the gorilla, both wild and in captivity, is that of relaxing the lower lip when in repose. It is not done when the creature is in a sullen mood, but frequently, when perplexed or in a deep study, this occurs. Another habit is that of protruding the end of the tongue between the lips, until it is about even with the outer edge of them. The end of the tongue is somewhat more blunted than that of the human. This habit is so frequent with the young gorilla that it would appear to have some meaning; but I cannot suggest what it is. In sleeping, the habit of the gorilla is to lie upon the back or side, with one or both arms placed under the head as a pillow. He cannot sleep on a perch,--as we have already noted,--but lies upon the ground at night. I had pointed out to me the place at the base of a large tree where a school of them had slept the night before. One imprint was quite distinct. The stories told about the king gorilla, or _ikomba_, placing his family in a tree while he sits on watch at the base is another case of supposition. The food of the gorilla is not confined to plants and fruits. He is fond of meat and eats it either raw or cooked. He secures a supply of this kind of food by catching small rodents of various kinds, lizards, toads, etc. It is also well known that he robs the nests of birds, taking the eggs or the young. A native once pointed out to me the quills and bones of a porcupine which had been left by a gorilla who had eaten the carcass. It is not at all rare for them to do this. The fruits and plants upon which they chiefly live are acidulous in taste, and some of them are bitter. They often eat the fruit of the plantain, but they prefer the stalk of that plant; this they twist or break open and eat the succulent heart. They do the same with the batuna, which grows all through the forest. The fruit of this plant is a red pod filled with seeds imbedded in a soft pulp. It is slightly acid and astringent. The wild mangrove, which forms a staple article of food for the chimpanzee, is rarely if ever eaten by the gorilla. I once saw a gorilla try to seize a dog, but whether or not it was for the purpose of eating the flesh I cannot say. One, however, did catch and devour a small dog on board the steamer Nubia, while on a voyage home from Africa. Both animals belonged to Captain Button, and from him I learned of the incident. Gorillas have no fixed hours for eating, but they usually eat in the early morning or the late afternoon. In a few instances I have seen them refuse meat. They are perhaps less devoted to eating flesh than the chimpanzee is.
