At the end of a week Wallace began to feed the ape with a spoon. He mixed soaked biscuit with egg and sugar, and sometimes with sweet potatoes. It took this food readily, and made droll grimaces in order to express its satisfaction or displeasure with what was offered. The little being licked its lips, drew in its cheeks, and screwed up its eyes with an expression of extreme content when it had a mouthful of anything it particularly liked. On the other hand, when the food was not sufficiently sweet and savoury, the orang turned it about in its mouth for a moment, as if to taste it thoroughly, and then spat it out. If the same food was presented again, it screamed violently and threw its arms about like a passionate child. Three weeks after Wallace obtained the young orang, a macaca (_Macacus cynomolgus_), likewise young, was brought to him. The two animals became at once the best of friends, neither showing the least fear of the other. The small macaca had not the slightest scruple about sitting on the other’s body, and even on its face. When Wallace fed the orang, the macaca sat by to pick up any morsels which dropped, and when the meal was over it licked off whatever remained on the orang’s lips, and even tore open its mouth to see if anything remained there; then it lay down on the poor creature’s body as if it were a comfortable cushion. The small, helpless orang endured all these insults with the most unexampled patience, only too glad to have something warm to cling to and encircle fondly with its arms. But it had its revenge, for when the other little ape wished to get away, the orang held on as long as possible to the movable skin of the back or head, or to its tail, so that it cost the macaca many violent struggles to escape. Wallace carefully observed the different behaviour of these two animals, which were of nearly the same age. All the observations hitherto made show that very young anthropoids display a helplessness resembling that of children of about the same age, although other families of apes, in common with most young mammals, kittens, puppies, etc., early attain to greater activity and independence. When Wallace had kept the orang for about a month, and placed it on the ground, its legs straggled outwards, or it overbalanced itself and fell heavily forwards. When lying in its box, it would hold on to the edge, and once or twice it fell out in consequence. If allowed to be dirty or hungry, or otherwise neglected, it would cry loudly until it received attention, or sometimes would cough or struggle like an adult animal. If there was no one in the house, or if no one paid attention to its cries, it would be quiet for a time, and only renew them when a step was heard.
