The Mental Life of the Monkeys 225

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. 1 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. 1, 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,
