of the cage; walked about the floor and climbed the front of the cage; to 

 the floor aud sat near the end of the cage; crossed the floor to the door and 

 climbed the front wire ; along the brace to J, where he perched ; to the floor and 

 looked about; to tlie door and up the front to A'; down to the floor, where 

 he sat looking out at the end wire; very alert, but the chute apparently 

 had no interest for him ; to the door and pushed, in an effort to get out ; 

 he had been very eager to get into the cage, but was now just as eager to 

 get out. 



Fifth trial, August 28. The behavior of No. 11 on this day was evidence 

 that he did not expect to find food in the cage. Most of his efforts seemed to 

 be directed toward getting out of the cage. There was no reason for his 

 desiring to leave the cage other than the lack of interest on the inside 

 and his desire to be back in the cage with his mate. He was not in the 

 least frightened. His behavior was as follows: Up the end of the cage and 

 down to the floor; up the front and down to the door; about the floor and 

 to the top of the wire front ; around to the top and down to X, where he sat 

 for some time, uttering a cooing call ; after a short time, to the floor and 

 about ; sat down near the wire end for a time ; up the front and shook 

 the cage; to X and perched; to the floor and grabbed the front wire, shaking 

 the cage very vigorously ; up to X and perched for some time ; down to the 

 floor and back up to X; along the brace and back to X, where he stayed during 

 the remainder of the time. 



Imitation tests. — No. 11 imitating No. 4. First test. No. 11 was placed 

 in the observation-box, which was then placed on the floor of the cage; No. 

 4 was free in the cage. No. ll's record in seeing was : 



Performance 1. No. 11 was distracted ; saw No. 4 on the chute, but did not 

 see the pulling of the string. He saw her eat the food on the floor. 



P. 2. No. 11 saw No. 4 on the chute ; saw her swinging at the end ; saw her 

 pull the string and get the food. 



P. 3. No. 11 saw No. 4 leap to the chute, swing down, pull the string, aud 

 get the food. 



P. 4. No. 11 saw No. 4 on the chute; saw her swing down and get the 

 food ; he jumped at the side of his box in an effort to get out. 



No. 4 now spent some time on the floor getting food and No. 11 watched her 

 attentively passing from one end to the other of his box as No. 4 walked about. 

 Several times he jumped at her striking the side of his box ; when she climbed 

 upon his box he became very threatening. 



P. 5. With his eyes No. 11 followed No. 4 about the floor and up over his 

 box to the chute. During the pulling of the string his eyes were riveted on 

 her. She dropped one seed in his box and he ate it. 



P. 6. Same as P. 5, except that No. 11 did not get food. No. 11 was very 

 threatening toward No. 4. 



No. 4 was now removed and No. 11 was released in the cage. His first 

 movement was to work at the door in an effort to get out of the cage. He 

 then went up to the brace, leaned over to the chute and placing one hand on 

 the side of it, attempted to pull it toward him ; he then grabbed the edge of 

 the lower end of the chute in his hand and pulled. Letting go of the chute
