Berry, Imitation in White Rats. 351 



running back and forth from No. 2 to the door. Part of the time 

 he would stand halfway between him and the door, looking from 

 one to the other, and the moment No. 2 got the door open he would 

 dash through it in front of him. 



Before beginning the experiment with No. 2 and No. 8, I put 

 No. I in with No. 8. Neither paid much attention to the other. 

 Again at the conclusion of the experiments with No. 8 and No. 2 I 

 put No. I in with No. 8. No. 8 followed No. i quite closely but 

 No. I paid little attention to him. When No. 8 was not following 

 No. I, he was running back and forth from him to the door.

The first time No. 2 was put in with No. 5, No. 5 paid little or no 

 attention to him, but after No. 2 had got out twice No. 5 began to 

 follow him, stand up beside him at the knot, and run to the door 

 and back. In all the trials, not once did No. 5 try to pull the knot. 

 When put in by himself he frequently would smell of the knot, 

 or near the knot, and then run directly to the door. He finally 

 became very dependent upon No. 2, and made but little effort to get 

 out when put in alone.
