cheek-pouches, to be chewed and swallowed later. This 

 arrangement is far from universal — ^it is absent in all 

 the New World monkeys and in some Old World 

 forms, but it is nevertheless common. 



As, with the exception of baboons, and of the Tibetan 

 and Himalayan forms already mentioned, all Primates 

 are denizens of the tropical forest, it is impossible to 

 name aU the members of the order here — a few ex- 

 amples only can be picked out. 



Apart from man, the highest living forms are the 

 anthropoid apes, of which there are four living kinds — 

 the gorilla and chimpanzee from West Africa, the orang 

 in Sumatra and Borneo, the gibbons from South-East 

 Asia. Like man himself, and like most Primates except 

 the lemurs, the anthropoid apes are diurnal in habit, 

 not nocturnal, Kke many mammals. The goriUa and 

 chimpanzee resemble man in the region which they 

 inhabit in having dark skins 'and hair ; the body is of 

 course much more hairy than in man. The goriUa, 

 which has a very limited distribution, is a dweller in 

 dense forest regions, and is an extraordinarily powerful 

 animal. It is purely vegetarian and fruit-eating, shar- 

 iiig a taste for some fruits with the negroes of the 

 region, and also consuming some which the negroes do 

 not care for. The fact that it robs human plantations 

 shows that food is sometimes scarce, even though the 

 animals appear to be very few in number. Wild plan- 

 tains and ' palm cabbage ' are freely eaten. 



The chimpanzee, which extends into Central Equa- 

 torial Africa apparently, at least at times, eats some 

 animal food in addition to fruit. 



Very different in appearance from the gorilla and 

 chimpanzee is the orang, with its very long arms and 

 its covering of long reddish hair. The way in which
