made no effort to pull the wire when put back after having seen 

 No. 2 pull the wire twice. He went to the wire and smelled of it. 

 But the third time when put back he went to the wire, pulled it 

 hard and then ran to the door; the door being only partly open he 

 w^ent back and pulled the wire again.

No. I was first put in alone for ten minutes. He struck the 

 wire with his nose but made no effort to pull it. The first time 

 he was put back after having followed No. 2 out he went to the 

 wire and pulled it and ran to the door, but he did not pull it quite 

 hard enough. He made no further effort to pull the wire until put 

 back for the sixth time when he pulled it a little with his teeth. 

 After the ninth trial I used No. 4 in place of No. 2. No. i followed 

 No. 4 even more closely than he had followed No. 2.

No. 3 was first put in the box alone for one hour. He made no 

 effort to pull the wire. No. 3 followed No. 2 quite closely, but 

 when put back he made little or no effort to get out. After No. 3 

 had followed No. 2 out twice I put in No. 4 once in place of No. 2. 

 No. 3 follow^ed him just as readily as he had followed No. 2. I 

 made only the four trials because No. 3 was unwell, since he 

 coughed almost constantly. A few days later I tried No. 3 again
