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.

Nearly all the above-named species are now living in the 

 Primate House, besides which there are many others. So 

 far as the available supply of captive primates will permit, 

 these typical species will constantly be kept on exhibition, 

 together with many others equally interesting. In this
