Haggerty, Imitation in Monkeys. 397 



Fourth test. This test was made forty-seven days after the preceding one. 

 The conditions were the same as in the preceding test except that No. 6 

 was used instead of No. 2. 



Performance 1. No. 9 saw and was just bacli of No. G when he tore the 

 paper. 



P. 2. No. 9 was on the bacli of No. G, but his head was turned away. 

 Because No. 9 insisted on riding on the cab baciv of No. G, the latter was 

 removed and No. 2 was substituted. 



P. 3 to P. 7. No. 9 saw No. 2 at the paper from front wire and came 

 down to it. He reached his hand in to get food, but No. 2 had talien it all. 



When No. 2 was out No. 9 came down from the wire, climbed the screen 

 frame, and sat on the edge. He jumped to the wire front, but at once 

 returned to the corner by the paper and sat on the floor for some time 

 looking at the paper and at that part of the cage. He then climbed the 

 front of the cage. Twice he came to the floor, climbed the frame at the 

 paper and jumped back to the wire front. After spending some time about 

 the cage and on the floor, he climbed the screen frame and tried to bite 

 the paper. He was too small to reach the hole from the floor and when he 

 got upon the lower edge of the frame his body covered the place where he 

 should bite the paper. 



Fifth test. No. 9 and No. 2 were in the cage together. Since No. 9 was 

 so small, a box was placed on the floor below the paper so that he 

 could climb upon it and thus have a more nearly equal chance with the 

 larger animals in exerting his force against the paper. 



P. 1. No. 9 saw from the middle of floor. 



P. 2. No. 9 saw in part. 



P. 3. No. 9 saw from the wire front above the brace. 



P. 4. No. 9 did not see the paper torn and did not come down for some 

 time. He saw No. 2 eat the food, sitting on the box. 



During each of the previous times he had searched the hole for food and 

 got none. He now paid no attention to the place. No. 2 was allowed to 

 continue eating food at the opening. No. 9 ran all about the cage, but paid no 

 attention to No. 2 and the paper. Finally No. 9 went to the box and got 

 sunflower seed and a piece of banana. 



P. 5. No. 9 saw from the top of the wire front. He came down for food 

 and No. 2 punished him ; he ran up the cage crying. 



P. 6 to P. 10. Did not see. Watching the experimenter. 



P. 11 to P. 12. No. 9 saw from above X. 



No. 2 was now removed. No. 9 ran up and down the wire and about the 

 floor. Tlieu he went to the box. He looked about for a moment and then 

 pushed his hand over the upper part of the paper above the hole and around 

 the upper edge of the paper. He looked at it and then climbed the wire 

 and went about the cage. 



After climbing about the cage, he came back to the paper, and put his 

 hands against it. He did not get his hand over the opening, although he 

 rubbed them about the paper considerabl}^ He then played about the cage.
