of communication between outside and inside cages, floors 

 and walls impervious to moisture and disease germs, and the 

 absence of iron bars from all cages save three. 



During the months of mild weather, all the inmates of the 

 large interior cages occupy, at will, corresponding cages 

 in the outdoor series. It is also intended that certain hardy- 

 species of baboons, and the red-faced monkey of Japan, 

 shall be provided with comfortable sleeping quarters and 

 live outdoors, every winter. It is believed that they can 

 do this, not only with comfort, but with great physical 

 benefit.

 versal understanding of the primates, we propose to set 

 them forth in four groups, a subdivision strictly according
