The Mental Life of the Monkeys 225 



Record: - - By himself, 10 F. Put through 80 times. F 65 

 (a) [the (a) refers to a note of his unrepeated chance success 

 with his head]. No similar act unsuccessfully attempted. 

 Influence of tuition, none. 



With the chute mechanisms the record would be of the 

 same nature. With them I put the animal through gener- 

 ally by taking his paw, held out through the wire netting of 

 the cage, and making the movement with it. In one ex- 

 periment (No. 3 with QQ chute) the first 58 trials were made 

 by taking the monkey outside the cage and holding him in- 

 stead of having him put his paw through the netting for me 

 to take. 



Many of the experiments were with mechanisms which 

 had previously been used in experiments concerning the 

 ability to learn from seeing me operate them. And the 

 following Table (12) includes the results of experiments of 

 both sorts. The results of experiments of the ' on chair ' 

 type are in Table 13. In cases where the same apparatus 

 was used for both purposes, the sort of training which was 

 given first is that where an A is placed. 



In the first four experiments with No. i there was some 

 struggling and agitation on his part while being held and put 

 through the act. After that there was none in his case ex- 

 cept occasional playfulness, and there was never any with 

 No. 3 after the first third of the first experiment. The 

 monkeys soon formed the habit of keeping still, because it 

 was only when still that I put them through the act and that 

 food resulted. After you once get them so that they can 

 be held and their arms taken without their clinging to you, 

 they quickly learn to adapt themselves to the experiments. 



With No. i, out of 8 cases where he had of himself failed 

 (in five of the cases he had also failed after being shown by 

 me), he succeeded after being put through (13, 21, 51, 10, 7,
