Haggerty, Imitation in Monkeys. 427 



In none of his movements did he display tlie same eagerness and expectation 

 as in the previous trial. 



Third trial, August IT. On this day No. 1.3 was even less active than on 

 the second day. He went up the wire to the brace and returned to the floor, 

 going to the door, pushing on it and passing around to L. He then carried 

 21c up to X and bit at the string, dropping it almost immediately. Then he 

 climbed the wire, but returned to A', where he perclied and I'emained for 

 some time looking about the cage. I^ater lie went to the floor and examined 

 all around the edge of the floor, but soon returned to X, where he remained 

 for some time again. Twice later he climbed the wire to tlie top, but spent 

 all the rest of his time at X, looking about the inside of the cage and out 

 through the wire. 



Fourth trial, August IS. The behavior of No. 13 was about the same as 

 in the preceding trial ; he climbed to A and returned to the floor ; he touched 

 51c and ^A"; then he carried 21c up to A and bit at the string, dropping it after 

 a moment. For several minutes he sat at A. Then he drew 77c up to him 

 and worked at it for some time. At first he worked directly at the knot and 

 made some progress toward untying it. Then, as if discouraged, he began 

 biting and pulling the protruding end of the string. At the end of several 

 minutes' continuous work lie dropped Ik and went to the floor, tried to climb 

 the post at 5 and passed on to 2l\ which he carried up to X, where he 

 chewed at the knot in the string. After a moment he let it drop and swing 

 back to its place. Two minutes later he went to the floor and to L, at which 

 he looked intently. Climbing the wire to A, he perched for the remaining 

 few minutes he was in the cage. 



Fifth trial, August 19. No. 13's behavior was about the same as on 

 the previous day. He climbed up and down the wire several times and 

 examined around the edge of the floor. Carrying 21c up to X, he bit at the 

 knot once and dropped it. Then he played up and down the wire, and going 

 to the door tried to open it, afterwards carrying 61c up to X, biting it and 

 dropping it when he climbed higher up the wire. He climbed to the upper 

 part of the wire and chewed at the edges of the cage frame, but quit when 

 spoken to. Again he carried 61c up the side and end of the cage, dropped it, 

 and settled at X for several minutes. Later he went to the floor, to L, 

 to the door and carried Gk up to X. He dropped it at once and remained 

 quiet. Once again he went to the floor and carried 21c up to X, where he 

 chewed the string and licked the knob. 



Imitation tests. — No. 13 imitating No. 5. — First test. No. 13 was put into 

 the observation-box and the box was placed on the floor of the experiment 

 cage exactly in front of L. This position enabled No. 13 to see all the move- 

 ments of No. 5 in getting food. No. 5 was free in the cage. The two animals 

 had never been together before and No. .5 was much frightened. Instead of 

 working at getting food she crouched in the corners of the cage and occa- 

 sionally dashed at No. 13 as if to frighten him. Once No. 5 ran up the wire 

 end and leaning over to 2t pulled it with her teeth. No. 13 did not see the 

 pull, but he saw No. 5 leaning over to the place. He became demonstrative, 

 and No. 5 did nothing but crouch for several minutes. The observation-box
