24 TRAITS OF YOUNG CHIMPANZEES 



much less conspicuous, are used differently in that the lower 

 one is seldom made a temporary repository of food. 



Whereas Panzee in both facial appearance and manner 

 suggested the Irish type, Chim similarly suggested the 

 Negro. 



Panzee 's hands and feet were smaller and more delicate 

 than those of Chim, and she was considerably less fleshy and 

 less well developed than he when the animals were received. 

 Whereas he was conspicuously well developed as to chest, 

 limbs, etc., and extraordinarily strong and energetic, she was 

 thin, weakly, and inclined to quiescence. It was at first 

 supposed that temperamental differences rather than 

 physical condition were responsible for the contrasting 

 behavior of the animals. 



Panzee in August, 1923, possessed the regulation quota of 

 twenty milk teeth. With the exception of a broken incisor 

 in the upper jaw the teeth were in fair condition, and were 

 white as compared with Chim's. Possibly her bad physical 

 condition had retarded dental development. In favor of Mr. 

 Lewis' estimate that her age was slightly greater than that 

 of Chim are the cranial measurements and the fact that she 

 was master of the cage when she chose to assert herself. I 

 am inclined to believe that her age also was somewhat under- 

 estimated by Mr. Lewis and that when received by me in 

 August, 1923, she was at least three years of age. 



Because of the obvious ill health of Panzee, continuous 

 effort was made to discover the nature of her complaint and 

 to improve her condition by out-door life, exercise and care- 

 ful feeding. 



In October, 1923, examination indicated that both animals
