Imitation tests. — No. 10 imitating No. 11. — First test. No. 10 was in the 

 observation-box on the floor of the cage. No. 11 was free in the cage. No. 10 

 was attentive to what No. 11 did. 



P. 1 to P. 5. No. 10 saw perfectly. 



No. 11 was then removed and No. 10 was released in the cage. Imme- 

 diately she climbed the end to the top and looked back to the floor, to the 

 door, and to the screen. She went to the front, still looking downward. 

 She went to the floor, to the door, and looked at the paper. She turned and 

 climbed the end of the cage again. She went to the front of the cage and 

 looked down at the door and the paper. She went down as far as the brace 

 and looked at the screen. Then she went to the floor, put her hands on the 

 lower edge of the frame and looked at the paper carefully. She turned back 

 to the end of the cage and climbed the wire. Again she went down to the 

 brace and surveyed the floor. She went down to the door and then climbed 

 the wire end again. She repeated this within one minute. She seemed more 

 interested in escaping than in getting food. Again she went to the floor, 

 looked about beneath the frame, and again climbed the end of the cage. 



Second test. Conditions same as in previous test. No. 10 was very atten- 

 tive to the movements of No. 11 and saw as follows : 



P. 1 to P. 3. No. 10 saw perfectly. 



She tried to get out of the observation-box and shook it vigorously. 



P. 4. No. 10 saw perfectly and shook the box. 



P. 5. No. 10 saw fairly well. 



When No. 11 was released, she ran up the end of the cage. She went 

 to the front and looked at the door and floor. She went to the floor and 

 about to the door. She climbed the end of the cage and returned again to 

 the floor ; she went to tlie paper and put her left hand on upper part and 

 pushed ; then she put her right hand on the lower part and pushed. Then 

 she climbed the end of the cage and held fast to wire with head turned back
