“He pursued his object with equal pertinacity when he felt a desire for the sugar or fruit which was kept in a cupboard in the eating-room; he would suddenly leave off playing and go in an opposite direction, only altering his course when he believed that he was no longer observed. He then went straight to the room and cupboard, opened it, and made a quick and dexterous snatch at the sugar-box or fruit-basket, sometimes closing the cupboard doors behind him before beginning to enjoy his plunder, or, if he was discovered, he would escape with it, and his whole behaviour made it clear that he was conscious of transgressing into forbidden paths. He took a special, and what might be called a childish, pleasure in making a noise by beating on hollow articles, and he seldom omitted an opportunity of drumming on casks, dishes, or tin trays, whenever he passed by them--a noisy amusement to which he was much addicted during our homeward voyage on board the steam-vessel, in which he was at liberty to roam about. He very much disliked strange noises. Thunder, the rain falling on the skylight, and especially the long-drawn note of a pipe or trumpet threw him into such agitation as to cause a sudden affection of the digestive organs, and it became expedient to keep him at a distance. When he was slightly indisposed, we made use of this kind of music with results as successful as if we had administered purgative medicine.” My personal observations enable me to add but little to this excellent and exhaustive account. It is well known that this ape throve in the Berlin Aquarium. His skin, especially on the extremities, was at first covered with dry, cracked patches, which the late veterinary surgeon Gerlach believed to be due to mange; but these gradually disappeared, and as they scaled off the skin became smooth and of a dark black colour, and there was a fresh growth of hair. The creature generally slept in the bed of his keeper Viereck, covered himself up in an orderly manner, and ate at the man’s table of plain but nourishing food, cooked by the keeper’s wife. He sometimes ate fruit, and bananas were occasionally provided for him. When taking his meals, drinking, etc., I saw that he always behaved with good manners. He often moved freely about in an office-room of the Aquarium, and he was as obedient to the Director as to his keeper. He was generally good-tempered, fond of play, but rather mischievous, and he would snatch roughly, and occasionally try the sharpness of his teeth. Sometimes he tried to seize from visitors things which attracted his curiosity, such as the trimmings of ladies’ bonnets, lace falls, and the like. But on the whole he behaved with propriety, playfulness, and good temper, and there was much which resembled man in his look and bearing.
