544 WILD ANIMALS. 



ultimately stretched out her arm, seized it, and instantly bolted. 

 Chimp in a moment was after her, and seizing her by her long 

 hair, pulled her backwards, and apparently tried to jump up and 

 down on her procumbent person, till she let go the coveted dainty. 

 Anyhow, both Susan and Sarah are amazingly human in their 

 looks, and I am sorry to say in their actions also, though Chimp 

 evidently has most brains of the two." 



That chimpanzees are capable of feeling some emotions that 

 are similar to those experienced by human beings was almost 

 established by the behaviour of an animal that was kept in the 

 Philadelphia Zoological Gardens some years ago, which on the 

 death of a companion gave evidences of a certain degree of 

 genuine grief. Two specimens occupied the same cage for some 

 months, and were much attached to one another, exhibiting their 

 affection in much the same way that children do, being seldom 

 seen apart, and generally with their arms about each other's neck. 

 " They never quarrelled," writes Mr. Arthur B. Brown,^ who 

 appears to have studiously watched these animals, " even over a 

 pretended display of partiality by their keeper in feeding them, and 

 if occasion required one to be handled with any degree of force, 

 the other was always prepared to do battle in its behalf on the first 

 cry of fright. After the death of the female, which took place 

 early in the morning, the remaining one made many attempts to 

 rouse her, and when he found this to be impossible his rage and 

 grief were painful to witness. Tearing the hair, or rather scratch- 

 ing at the short hair on his head, was always one of his common 

 expressions of extreme anger, and was now largely indulged in, 

 but the ordinary yell of rage which he set up at first finally 

 changed to a cry which the keeper of the animals assures me he 

 had never heard before, and which would be most nearly repre- 

 sented by hah-ah-ah-ah-ah uttered somewhat under the breath, and 

 with a plaintive sound like a moan. "With this he made repeated 

 efforts to arouse her, lifting up her head and hands, pushing her 

 violently and rolling her over. After her body was removed from 

 the cage — a proceeding which he violently opposed — he became 

 more quiet, and remained so as long as his keeper was with him,
