varied the experiment by passing the chain round a 

 high "grandfather's chair/' standing in the corner of 

 the room. (Fig. i.) The way round would be quite 

 dark and unobvious, but I wished to see whether he 

 would draw the analogy from the table. The result was 

 as follows : 



He makes great effort to reach potato, tries to use hammer as 

 stick to reach it, tries to move chair, turns and pulls with hands 

 at rope, makes (for first time that I have seen him do it) a sort of 

 dash at a point where his chain is fastened, but does not think of 

 going round chair. 



I take chain from chair and put it round table. As I arrange, 

 he is excited, wanders, and gets entangled. Cannot disentangle 

 himself. I do so, and let him have some potato. Then I replace 

 round table. After trying straight at potato, he at once darts 

 back, but instead of going outside, leaves one leg to the right, 

 table standing thus :

He then gets entangled, but disentangles himself by stages, and, 

 getting free, goes somewhat hesitatingly round table and gets 

 potato. 



Replaced. He makes exactly same mistake, but rapidly 

 disentangles himself through three or four turnings, runs round 

 table and gets. 



Total time can only have been a few seconds.
