In the age of Linné, the apes of which we speak were but imperfectly known. Even now-a-days our information upon the subjects of their intelligence, manners, and habits, is defective and fragmentary. The individuals whom we have retained in captivity have died while very young, and it is impossible to say whether their early mildness and intelligence would have proved as transitory in them as in the Macaucos and the Cynocephali, who, as they advance in years, display the most brutal instincts. In their adult state, the Anthropomorphic Apes have not been really studied. Travellers have penetrated into their forests only to attack them with rifle-balls, and have told us but little of the manner in which they comport themselves. As for the details collected from natives inhabiting their vicinity, they are so contradictory, and mixed up with so much which is fabulous, that it is impossible to draw any conclusions from them in reference to the habits of these animals.
Four distinct genera of the Anthropomorphic Apes are now recognized by naturalists: two belonging to Southern Asia, or rather the great Indian Archipelago—viz., the Orang and the Gibbon; two to Tropical Africa—viz., the Chimpanzee and the Gorilla. I shall describe their peculiarities in my next chapter.
CHAPTER VII.
THE ANTHROPOMORPHIC APES:—ORANGS, GIBBONS, CHIMPANZEES, AND GORILLAS.
THEE genus Orang-Outang (Simia Satyrus), or “Wild Man of the Woods,” is a native of the islands of Borneo, Sumatra, and Java, and of a limited portion of the Malayan peninsula. We must dismiss as travellers’ fables the exaggerated recitals which attribute to this Ape a gigantic stature (six to seven feet). The tallest specimens which have reached Europe have not exceeded four feet in height. The Orang has short and feeble lower limbs; but his arms, on the contrary, are very robust, and of such a length that he can touch the ground while standing upright—a posture, however, which is neither natural nor convenient for him. His ordinary mode of locomotion consists in passing from one tree to another by swinging himself from branch to branch, his progress being as rapid as that of a swift horse, and his agility not less wonderful than that of our Leotards and Blondins. His body is covered with coarse reddish hair, whose shade varies according to his age. It is thick on the head, shoulders, and body, but thin about the fore-parts. The face has a bluish cast, and is partly naked; but the eyes sink under bushy, prominent eye-brows, and the upper lip, chin, and cheeks are garnished with a sort of longish beard. Naked are the exterior face and palm of the hands. Where the skin is deprived of hair, its colour is of a hodden gray.
The Orang-Outang has a large protuberant belly, a flat nose, small ears, projecting muzzle, long, thin, and very extensible lips. In youth the forehead projects; but as the creature grows older, it becomes depressed at the same time that the face lengthens; the face assumes a more decided bestial type; and the intelligence, lively and quick at first, declines into obtuseness and atrophy. The head inclines forward; the neck is short, thick, and seemingly afflicted with gôitre, which is due to the presence of the pouch called thyroïdian. This pouch, placed above the sternum, extends beneath the arm-holes, and communicates with the larynx. When expanded, it is capable of receiving a great quantity of air, which, being afterwards expelled very slowly, and passing anew through the vocal organ, produces a dull and prolonged murmur.
The Orangs have now disappeared from Continental India, and even, we are assured, from Java, so that their chief habitats at present are Borneo and Sumatra; and here too they are few in number. The genus is rapidly dying out. Those which remain seek in the dense and marshy forests an asylum from the attacks of man, and a shelter against the climate. During the day, they traverse the summits of the trees in quest of food, for they subsist exclusively upon leaves, young shoots, tender bark, and fruits. At nightfall they conceal themselves amid the foliage of some moderately tall tree, or in the great tufts of orchids which flourish about the arboreal giants. There they make for themselves a couch like an even floor or platform, garnish it with leaves and interwoven branches, and stretch themselves upon it, or sit crouching, to enjoy their slumbers. It is said that when the necessity arises they spread over themselves a similarly-fashioned canopy as a shelter from the rain.
The Orang-Outang is timid and inoffensive; he rarely engages in a combat with his enemies. At times, however, when driven to extremities, he resorts to his great muscular strength in self-defence, and if he can succeed in grappling with his antagonist, he rends him to pieces with his tenacious hands; never using his teeth, although his jaws are very powerful, and armed with canine teeth capable of inflicting dangerous wounds. In general, when he feels himself sorely stricken, he hurriedly climbs to the summit of the loftiest tree within his reach, and if he finds himself still pursued, he passes on to another. Meanwhile he utters the most dolorous cries, and vents his impotent rage upon the tree which serves him for a refuge. One after another he breaks the greatest branches; but they immediately escape from his grasp, and fall to the ground. It is this circumstance which has originated the assertions of many travellers, that the Orang defends himself by hurling boughs at his aggressors, and even by striking them heavy blows with a stick. The truth is, that far from protracting his defence by the expedient his fury prompts him to adopt, he does but expose himself the more fully to the projectiles directed at him. The stripped tree is no longer available as a shelter. The Malay hunters, therefore, take no heed of all this fracas, but patiently wait until the Orang has exposed himself, to aim their arrows or rifle-balls with the greater certainty.
