of chute. Later she climbed to the chute, but paid no attention to it. Nor 

 did she pay any more attention to it during the entire time in the cage. 



Sixth test. The conditions were the same as in the previous test, except 

 that the string in the chute was lengthened four cm. Of seventeen per- 

 formances No. 5 saw five completely, six in part, and six not at all. Toward 

 the end of the time she seemed sleepy and paid but little attention. 



When No. 2 was out and No. 5 was released she at once climbed to the 

 chute and took a long, steady look up the inside of it, but did not put 

 her hand up. Time : 40 seconds. She then took her leisure about the cage, 

 caught a roach and perched on the brace. 



Summary of Behavior of No. 5 in Chute Experiment B. 



No. 5 did not present the same pi'oblem in the imitation tests as the 

 animals previously discussed. She had already performed every part of 

 the act necessary to get food. She had evidently failed because of not 

 exerting sufficient strength. Her intei*est in the chute seemed to wane in 

 the fourth and fifth preliminary trials and to be accentuated after observing 

 No. 2 in the first and second tests. During the later tests she repeated 

 the act of the animal seen, but she never got the food, and in the fifth test 

 she merely l.ooked up the inside of the chute without putting her hand in. 



It seems fair to infer that the increase of interest manifested in the first 

 and second tests and the continuation of interest in the chute through the 

 successive tests was due to No. 5 seeing the other animals getting food at 

 the end of the chute.

Preliminary trials. — First trial. No. 3 moved about slowly in the cage 

 during the entire fifteen minutes, but gave no attention to the device for 

 getting food. He spent his time on the floor and the wire parts of the cage. 



Second trial. No. 3 spent the first few minutes on the fioor and then 

 climbed the wire and came back to the floor several times. Once when on
