ZOOLOGICAL SOCIETY BULLETIN 



'9 



As a thoroughly scientific plant for the suc- 

 cossful care and satisfactory public exhibition 

 of 250 apes, baboons, monkeys, and lemurs, the 

 Zoological Society believes that it will bear 

 comparison with the best buildings of the kind 

 that have been produced thus far. Moreover, 

 its ground plan, cage designs, and service ar- 

 rangements are, in nearly every detail, entirely 

 new. These features are the hard-earned re- 

 sults of our own studies of living primates, 

 both in their native jungles and in many pliases 

 of captivity. 



GEN'ER.-\L CHARACTER. 



Like our other large buildings, the Primates' 

 House is only one story high. Like them also 

 its architectural style is classic, and its ma- 

 terials are buff brick, gray granite, Indiana 

 limestone, gray terra cotta, red slate, and 

 copper. It is 162 feet in length by 74 feet in 

 greatest width, including the outside cages, 

 which have a maximum width of 23 feet. The 

 main building consists of two lofty and spa- 

 cious halls, joined by a long central gallery. 

 At each end there is a wide entrance pavilion, 

 consisting of a central vestibule, flanked on 

 each side by rooms necessary to the service of 

 the building. All along the eastern front of 

 the building extends a series of lofty outdoor 

 cages. 



Although the interior of the main building is 

 divided into three halls, when the wide, interior 

 doors are open, the divisions detract but 

 slightly from the .general effect of one grand 

 gallery, 122 feet long, and 43 feet wide. Thi> 

 subdivision of the s])ace is a new idea in ani- 

 mal-house construction, and it gave the key- 

 note for the entire plan. The reasons for it are 

 as follows : 



1. More perfect control of interior tempera- 

 ture. 



2. The ability to maintain more than one 

 temperature. 



3. The scientific subdivision of the primates. 



4. The acquisition of a maximum of floor 

 space for animals. 



THE HAH,S. 



The South Hall is to be occupied exclusively 

 by the monkeys of the New World — the capu- 

 chins, spider monkeys, sakis, howlers (if they 

 will live), marmosets and owl monkeys. The 

 Main Hall is to be devoted to the baboons, mon- 

 keys, and lemurs of the Old World. The 

 North Hall is for the anthropoid apes — orang- 

 utans, chimpanzees, and gibbons, and also 

 gorillas, as often as good fortune renders it 

 possible to secure a specimen of that rare and 

 wonderful creature. 



THE INTERIOR CAGES. 



The interior of the building is provided with 

 cages of four different types. There are two 

 triple wall cages, extra large and light, and 

 four double wall cages, for the great apes, and 

 for large generic groups of South .\merican 

 monkeys. There are nine single wall cages, for 

 baboons and large monkeys. One cage is quite 

 spectacular, being very large, open on four 

 sides, and backed by a jungle of growing 

 plants. This is called the Jungle Cage, and 

 will contain a collection of lemurs and particu- 

 larly beautiful members of the Genus Scmno- 

 [fitlicciis. 



The fourth type consists of 22 fli)or cages, 

 which, though much smaller than any of the 

 preceding, are yet abundantly large for the shy 

 and delicate species which they will contain. 

 Strange as it may seem, there are many species 

 of mammals which are so timid and so delicate 

 every way, that they are happier, thrive better, 

 and live longer in comparatively small quar- 

 ters than when given a great amount of space. 

 To a very timid animal, the sense of being \no- 

 tected at all points is as necessary to its health, 

 as good air and sufficient warmth. 



The dimensions of the interior cages, not 

 counting their tables, are as follows : 



feet long, 10 feet deep, and 12 feet high 



icIliI lor, about Jjo specimens.
