 up to X, wbere be bit at it and dropped it. Tben be went to tbe floor, walked 

 about, and climbed back up to A', wbere be remained during tbe remainder of 

 tbe time. 



Tbird test. This test was made immediately after tbe previous one and 

 tbe conditions were tbe same. Tbe record of No. 13 was : 



Performance 1 to P. 5. No. 13 saw tbe whole performance and was very sav- 

 age in his demonstrations toward No. 5, jumping at tbe side of tlie cage with' 

 wide-open moutb. 



Only twice did No. 13 turn bis bead away from No. 5 and then only for a 

 moment each time. 



No. 5 was now taken out and No. 13 was released. He was very slow of 

 movement walking about the floor. Twice be went to L. and then climbed 

 tbe wire to A', where he perched for a little while. Going to the floor, he 

 passed tbe door and thence to L, looking into tbe hole several times. In one 

 baud be took 3k and in tbe other he took 2k, but did not pull at either. 

 Dropping botli he climbed tbe end of tbe cage, but returned at once to tbe 

 floor. Stopping at L, he clawed the opening with bis band and tben climbed 

 ttie wire to the brace. Going to tbe floor be tried the door wbere be had 

 entered the cage and went to L, returning again to tbe door. 



For several minutes he worked at tbe door trying to open it. Once be 

 stopped to turn about and look in at L, but renewed bis efforts at tbe door 

 immediately. Giving up opening tbe door, he went to L, took 3k in his 

 hands, dropped it and started to carry 2k up tbe wire, but dropped it; 

 climbed to A and perched, playing with 7 and 7k.

P. 5. No. 13 saw very well. 



P. 6 and P. 7. No. 13 did not see.

 Passing up by X, he tried to get up to 2k, but was not allowed to do so. He 

 returned to tbe floor and walked about ; <^imbed to X again ; and, returning 

 to the floor, be went to L and looked in. He then climbed to A and up and 

 down tbe wire end of tbe cage. Once again he went to L and put his hand 

 into the opening. 



Fifth test. No. 5 and No. 13 were put into tbe cage together this time. 



Performance 1. No. 13 was at X when No. 5 pulled the string tbe first 

 time; he saw her pull and saw her get food. Climbing down be got tbe

P. 2. No. 13 saw again from A and got the food as before. No. 5 was
