Secoud trial. Ou the second day the experimeut was disturbed by No. 2 

 getting out of the cage. During the time he was in the cage he made no 

 effort to climb the rope. 



Third trial. On the third day he went rapidly about the cage as on 

 the first day. Once, in passing, he picked up the end of the rope. During 

 the thirty minutes, however, he made no effort to climb it. 



Fourth trial. On the fourth day No. 2 was quite active and kept moving 

 during the entire thirty minutes, passing over every bit of floor space many 

 times and being repeatedly on every part of the front and end of the cage. 

 He noticed the rope only to touch it momentarily in passing. 



Fifth trial. On the fifth day No. 2 was active and eager to get out of 

 the cage. Once he grabbed the rope in his tail and ran up the front of 

 the cage. Later he bit the end of the rope once. 



Sixth trial. Oa the sixth day he was very wild, possibly due to the death 

 of his mate the day before. He made no effort to climb the rope. 



Seventh trial. Ou the seventh day No. 2 behaved as usual. His only 

 notice of the rope was to push it aside in passing. 



Eighth trial. No. 2 behaved as usual. Once he stood ou his feet and 

 grasped the rope with his hands one above the other as if to climb. 



Ninth trial. On this day No. 2 grasped the rope once in the same manner 

 as on the previous day, but let go of it at once. He repeated this several 

 times, but showed no other intention of climbing. He did not look up when 

 holding the rope. 



Tenth trial. On the tenth day he went about the cage in his usual way. 

 Once or twice he hooked his tail around the rope and ran up the front of 

 the cage, dropping the rope when half way up. 



Eleventh trial. On the eleventh and twelfth days he went about the 

 cage as usual and displayed no interest in the rope. 



Imitation tests. — No. 2 imitating No. 3. — These tests were made in New 

 York. Both animals were in the cage together. 



First test. No. 3 got food twelve times. Ten times No. 2 saw him eating 

 the food and once saw the entire performance. Twice when watching No. 3 

 eat while on the rope, No. 2 climbed the front wire and leaned toward the 

 rope as if trying to get to the door. During the rest of the time No. 2 

 was distracted by the other monkeys in the living cages nearby. 



Second test. No. 3 was very active and climbed the rope often and 

 rapidly. No. 2 was not accustomed to watch No. 3 and did not look at 

 him, but tried to see out the window and into the other cages. Four times 

 when No. 2 saw No. 3 on the rope he leaned out from the side of the 

 cage toward the rope. Once when No. 3 pushed the rope toward the front 

 of the cage No. 2 caught it in his hands and swung his weight on his 

 hands, but held on to the wire with his feet and tail. Several times when 

 No. 3 was up the rope No. 2 caught the end of it from the floor. No. 2 

 saw five times in fourteen. When No. 3 was taken out after performing
