button and bit it. He did not come back to the door and he went to many 

 other places in the cage as well as to the button. At other times, when 

 near it he paid no attention to the button. 



Second test. No. 6 was not so frightened as in the previous test and 

 remained on the floor near No. 4 five times in nineteen. He saw her push 

 the button and get food. The second and fourth times he saw No. 4 push 

 the button he went to it and looked out at the opening. 



When No. 4 was out No. 6 became very active with his teeth and hands 

 at the door. After nine minutes he went to the button and pushed it with 

 his hands, but as the push was directly toward the board, and not to one 

 side, as was necessary to open the door, he did not succeed. Later lie put 

 his liand on the screw eye. 



Third test. No. 6 watched more attentively than in the first test and saw 

 five times in twenty-seven. 



When No. 4 was removed No. 6 worked incessantly at the food door witli 

 his hands, feet, and teeth. He used his tail to thrust through the wire when 

 he could not reach around with his hand. Once he thrust his tail around 

 the corner of the cage and caught the string to which the banana was 

 attached. He was not allowed to get food in this way. He paid no attention 

 to the button during the time. 



Fourth test. No. 6 was more attentive than on any previous day and saw 

 five times in eleven. After seeing the fourth time he went to the button 

 and pushed with his hand, but not in such a way as to open the door. After 

 the fifth time he bit at the lower edge of the button. 



After No. 4 was out No. 6 did not go to the button. He worked more or 

 less intermittently at tlie door for ten minutes. 



Fifth test. No. 4 worked slowly and gave No. 6 a good opportunity to see, 

 but he was not attentive and saw only seven times in forty-one. Then his 

 look was not direct. The first time he saw, he went to the button and looked 

 through the hole behind it. 



When No. 5 was out No. 6 got food by fingering at the door. Then he 

 worked at the door and once bit the button, but he was not at all active. 



Sixth test. No. 6 kept his attention on the door during thirty-two per- 

 formances, but rarely turned his attention to the button even though No. 4 

 went from the door to the button and back to the door for food repeatedly. 

 His attention was almost wholly on the door. Ten times in the thirty-two 

 he saw No. 4 push the button. 



When No. 4 was out No. 6 became very eager at the door and continued 

 so for ten minutes, but did not once go to the button. 



Seventh test. No. 6 was quite indifferent to all the juovements of No. 4. 

 He often looked at the door as No. 4 left it to go to the button. It was not 

 clear whether No, 4's leaving the door suggested that the door was about to 

 open, or whether No. 6 was all the time interested in the door and showed 

 his interest only when No. 4 left the way clear. He saw five times In thirty- 

 five and then only by glances. 



When No. 4 was out No. 6 became at once interested in tlie door and 

 worked at it most of the time for five minutes. Then he ran about the cage, 

 but paid no attention to the button.
