like the one exhibited. The straight, sharply-pointed horns are 

 much in favor with East Indian sailors for use as marlinspikes. 



The zebu (Bos indicus), a domestic variety much bred in parts of 

 Asia and Africa, is shown in paddocks near the west gate. 



THE PRIMATES. 



The order of mammals known as the Primates includes the lemurs, 

 monkeys, apes, and man. The lemurs are mostly nocturnal animals 

 and are, so far as living forms are concerned, not closely related to 

 the other Primates. In some species the tail is very long; in others 

 it is wanting entirely. At the present age the lemurs are confined to 

 Africa, the oriental region, and to Madagascar and neighboring 

 islands. Many of the species are confined to the latter region. 



The other Primates are usually divided into several families. The 

 principal groups are the marmosets, small species often of brilliant 

 coloration and silky coat, confined to tropical America; the remain- 

 ing American monkeys, of great variety in size and characteristics 

 and of an uncertain number of families; the Old World monkeys, 

 all rather closely related as compared with the great diversity shown 

 by the American species ; the anthropoid apes, including the gorilla, 

 orang-utan, chimpanzee, and gibbon ; and finally man. 



While the majority of the Primates kept in the park are exhibited 

 in the monkey house, several outdoor yards and shelters are provided 

 for such species as endure our winters without heated quarters, and 

 the chimpanzee makes his winter home in a specially prepared corner 

 of the lion house. 



the chimpanzee (Pan troglodytes) . 



No animal in the park attracts so much attention from visitors 

 as " Soko," the chimpanzee. " Soko " reached the park in Sep- 

 tember, 1915, from the forests of the French Congo. He was then 

 about 3| years old and weighed only 38 pounds. During the autumn 

 of 1916, or when about 4| years old he lost his milk teeth and since 

 the permanent teeth have developed his growth has been much more 

 rapid than before. On September 1, 1918, he weighed 85 pounds. He 

 has been taught by his keepers to take his formal meals seated at a 

 table; and after his napkin has been adjusted he scans the menu, 

 writes his order, and rings his bell for service. Sliced bananas, rice 

 pudding, and other foods are eaten with fork and spoon in a con- 

 ventional manner, much to the joy of the children who crowd about 

 his cage. He pours his own milk from the bottle and has never but 

 once overfilled his glass, since which mishap he has always exercised 

 particular care not to waste this food.
