*No. 7 hit the string in his general struggling, apparently utterly without 

 design. He did not realize that the door was open till, two seconds after it had 

 fallen, he happened to look that way. 



2 No. 6, in trying to crawl out at the top of the box, put its paw in above 

 the string. It fell down and thus pulled the string. It did not claw at it, and it 

 was 16 seconds before it noticed that the door was open. In all the other times 

 that it escaped the movement was made in the course of promiscuous scrabbling, 

 never in anything like the same way that No. 2 made it.
