So far, therefore, she certainly showed no special 

 predilection for the blue. I then left her the rest 

 of the day to visit the honey on blue paper exclusively. 

 She made fifty-eight visits to it. The following 

 morning I opened my window at 6.15, when she im- 

 mediately made her appearance. 



I let her make ten more visits to the honey on blue 

 paper, moving it about a foot or so backwards and 

 forwardri on the table. I then put orange paper instead 

 of the blue, and put the blue about a foot off. She 

 returned to the orange. 



I put yellow instead of orange ; she came to the 



yellow.
