was found that he was so strong it took four men to hold him 

 before the wash could be applied. The female would spit 

 quite a distance between her closed teeth. The male never 

 learned this trick. The male was very fond of helping the 

 keeper clean the glass with a rag.* Many cockroaches came 

 into the cage, which they never ate, but seemed to be annoyed 

 by them when they crawled over them when asleep. The 

 male slept on his back with his arms thrown over his head ; 

 the female slept on her side. Each knew his or her name — 

 " Pat," or " Granny "—when called. 



Mr. Stephan thinks they mature at about twelve years of 

 age. At about five years of age they shed their front teeth. 

 It was very dangerous for a stranger to enter the cage. On 

 one occasion the male knocked a workman out completely. 

 Mr. Hostetter the keeper, could do anything with them, 

 though at times the}' would play tricks on him. A rubber 

 doll was given the male — one of those that emitted a cry 

 when squeezed. This pleased him very much ; he sat on it 

 and jumped up and down, but his rough usage soon wore it 

 out. After a few days another one was procured, one that 

 had a knit dress on, but lacked the crying attachment. When 

 this was given him he quickly squeezed it, but failing to hear 

 it cry, turned up its dress, looking at the spot where the first 

 one had the circular crying whistle set in its back, and 

 seeming perplexed and disappointed that this one was not 

 similarly provided. 



The first symptoms of the disease, consumption, (that de- 

 stroyer of caged monkeyst) that carried off the male, was 

 noticed nine^ months before his death, but he was only 

 observed to cough about three mouths before. The post- 

 mortem revealed tuberculosis ot the left lung, with complete 

 solidification and adhesions. When the male died the female 

 was, apparently, in good health. She seemed to miss the 

 male only for a day, though when he was taken out of the 

 cage, just before his death, she pulled her hair and rolled 

 around in a fearful rage because she could not go also. The
