of its distiiiguishiiig marks. These animals are large, strong, and 

 apparently conrageons. Both the cynomolgus and rhesus monkeys 

 have cheek ponches in which they store food. Roth make a show 

 of courage and, in comparison with the Cebiis monkeys, are quite 

 courageous. 



(&) Characteristics of Individual Animals. — Ko. 10, Macacus 

 rhesus, female, was four years old and had been in the Park more 

 than a year, during which time she had been caged with a large 

 female common macaque. Both of these animals had an apparent 

 dislike for strangers and would dash at the side of the cage when 

 any one apj^roached. Xo, 10 was in the laboratory oidy three 

 weeks, in a cage with No. 1 1, a male of her own species. She 

 was much afraid of me at first and rushed about the cage to get 

 away. She soon became quiet and for ten days was an exceptionally 

 good animal for study. She was active, quick and hungry. Before 

 the tests with her were over, she was attacked with dysentery and 

 became useless for experimentation. 



Tso, 11, Macacus rhesus, male, was a young animal about three 

 3'ears old but very large. He had a long well-rounded body, well- 

 shaped lind)s, and well-developed quarters. During the time he 

 was in the laboratory he was in superb physical condition. He was 

 quick, active and strong. He seemed never to be otf his guard. His 

 muscles were alwa^'s tense and he leaped suddenly and with great 

 force. He was not afraid, but would not allow himself to be handled. 

 jSTo. 10 whipped him, but he showed tight toward all the other ani- 

 mals and never retreated. 



No. 13, Macacus cynomolgus, male, was a large vigorous animal 

 about four years old, who w\as not afraid of persons or other ani- 

 mals, yet who was not of a pugnacious disposition. He whipped 

 No. 12, his cage mate, while they were in the laboratory, but after 

 he had settled the supremacy of the cage he lived peaceably with 

 him. Like No. 11, he was always attentive to other animals and 

 seldom failed to see anything he could turn to his own advantage. 

 He was quick and strong, and during the experiments, was in fine 

 physical condition.
