THE SPEECH OF MONKEYS. 37 



quiry I found that he had been confined in a cage 

 with the white-face for nearly four years, and 

 hence my belief that he acquired them during 

 that time. 



The most remarkable case which has come un- 

 der my observation is one in which a young 

 white-face has acquired the sound which means 

 food in the Capuchin tongue. This event oc- 

 curred under my own eyes. I regard this case 

 as so noteworthy, being attended by such con- 

 ditions as to show that the monkey had a motive 

 in learning the sound, that I shall relate it in 

 detail. 



In the room where the monkeys were kept by 

 a dealer in Washington, there was a cage which 

 contained a young white-faced Cebus of rather 

 more than average intelligence. He was a quiet, 

 sedate, and thoughtful little monkey, whose gray 

 hair and beard gave him quite a venerable as- 

 pect, and for this reason I called him Darwin. 

 From some cause unknown to me he was afraid 

 of me, and I showed him but little attention. 

 On the same shelf and in an adjacent cage lived 

 the little Capuchin, Puck. The cages were only 

 separated by an open wire partition through 

 which they could easily see and hear each other.
