Equal in size to, but much stronger than, an English mastiff is the Chacma, or Pig-faced Baboon (_Cynocephalus porcarius_), of the Cape of Good Hope, where he inhabits the mountains, and makes frequent forays in the gardens and plantations around Cape Town. His yells and screams make night hideous. He wears a sober livery of an uniform dark brown colour, with long shaggy mane-like hair about his neck and shoulders. His skull is contracted and flattened, his muzzle extremely prolonged, and the cheeks of both sexes are ornamented with small grayish whiskers. * * * * * We must now direct our attention to the Anthropomorphes, or Apes with a semi-human form, which, of all the Quadrumana, approach nearest to man in form, stature, internal and external conformation, manners, instinct, and development of intelligence. They have no tail, and the Gibbons (_Pithecus lar_), which occupy the lowest rank among them, possess only the rudiments of ischiatic callosities. Nor are they provided with those dilatable pouches worn by a great number of other Primates on each side of the mouth, and named by French naturalists _abajoues_. Their position, when they move along the ground, is bent rather than erect, and they assist themselves by their extraordinarily long anterior arms. These arms, in fact, are much longer than their legs; their thumbs, at the four extremities, are opposed to the other fingers; the palm of their hands and the sole of their feet are naked, as well as their face. The sternum is large and flat; the clavicles are short and well articulated.
