Seventh test. No. 4 was very active and eager for food. No. 2 was fairly 

 attentive, but No. 4 worked so rapidly No. 2 saw but twenty times in forty. 



After No. 4 bad been taken out No. 2 worked at the lower edge of the 

 screen and at the frame. For ten minutes he kept persistently at the screen, 

 biting and fingering the frame. Not once did he push against the screen to 

 lift it. 



Eighth test. No. 2 watched No. 4 at the outset very closely. After seeing 

 her get food seven times he reached his hand to hers to get some food, but 

 he was severely slapped. He made no effort to work at the screen while No. 

 4 was present. 



After No. 4 had been taken out, No. 2 went to the screen and tried to 

 manipulate it. He used his hands at the lower edge of the screen and bit 

 at the screen frame. He kept at it most of the time during the ten minutes. 



Ninth test. No. 2 was attentive to No. 4 at first, but when he failed to 

 get food he became indifferent and looked at other things than No. 4. He 

 kept near her, but at a safe distance. 



After No. 4 had been removed No. 2 became interested in the screen at 

 once. He fingered the crack at the lower edge, and bit at the frame. He was 

 not persistent, however, and soon went to other parts of the cage. He 

 returned later to the screen for a moment. 



Tenth test. No. 2 was not inclined to watch No. 4, but spent his time 

 in picking scraps from the floor. Once he went from the far part of the 

 cage and pushed lightly against the lower edge of the frame with his hands. 



After No. 4 had been taken out No. 2 spent his time on the floor. Once 

 only he went to the screen ; then he fingered the lower edge, but did nothing 

 more.

Sum 111(111/ of Behavior of No. 2 in the Screen Experiment. 

 As in the case of No. .5 and No. 6, No. 2 had gotten food in the Paper 

 Experiment and had frequently seen the screen lifted. In his preliminary
