OF WILD ANIMALS 83 



His nervous temper and his forced-draught activities soon wear 

 him out. If he survives to see his sixth or seventh year, 

 it is then that he becomes so strong and so full of ego that 

 he becomes dangerous and requires to be retired. 



Bright minds are more common among the chimpanzee 

 species than among the orangs. Three chimps out of every 

 five are good for training, but not more than two orangs out 

 of five can be satisfactorily developed. 



Some sensitive minds shrink from the idea that man has 

 "descended" from the apes. I never for a moment shared that 

 feeling. I would rather descend from a clean, capable and 

 bright-minded genus of apes than from any unclean, ignorant 

 and repulsive race of the genus Homo. In comparing the chim- 

 panzees of Fernan Vaz with the Canoe Indians of the Strait

The face of the chimpanzee is highly mobile, and the mouth, 

 lips, eyes and voice express the various emotions of the indi- 

 vidual with a degree of clearness and precision second only to the 

 facial expression of man himself. In fact, the face of an intelli-

 expansive lips and keen brown eyes express contentment, 

 doubt, fear and terror; affection, disapproval, jealousy, anger, 

 rage; hunger and satiety; lonesomeness and illness. 



The lips of the chimpanzee afiford that animal several per-

 While it is not possible to offer a description of each which will 

 certainly be recognizable to the reader, the two extremes will 

 at least be appreciated. When coaxing for food, or attention, 

 the lips are thrust far out beyond the teeth, and formed into a 

 funnel with the small end outermost. When the chimpanzee 

 flies into a rage at some real or fancied offense, the snarling lips
