CHOICE OF COLOR 31 



same color, and also that the same monkey does not at 

 all times choose the same. But, as a rule, bright green 

 appeared to be the favorite color of the Capuchins, and 

 their second choice was white. In a few instances white 

 appeared to be their preference. This experiment was not 

 confined to candies, nuts, or other eatables. They appeared 

 to use about the same taste in selecting their toys. From 

 the use of artificial flowers, it appeared that the choice of 

 green was possibly associated with their selection of food. 

 On one occasion I kept a cup for a monkey to drink milk 

 from. On one side of this was a picture of some bright 

 flowers and green leaves. The monkey would sometimes 

 quit drinking the milk and try to pick the flowers off the 

 side of the cup. The fact that she could not remove the 

 flowers appeared to annoy her, and she seemed not to 

 understand why she could not get hold of them. 



In one test I used a board about two feet long, upon 

 which were a few pieces of white and pink candies, mixed 

 and arranged in four different places on the board. The 

 monkey selected the white from each pile before taking 

 the pink, except in one instance, in which the pink was 

 taken first. In another experiment I took a white paper 

 ball in one hand and a pink one in the other and held my 

 hands out to the monkey. He selected the white one 

 almost every time, although from time to time I changed 

 hands with the balls. It was not a mere matter of con- 

 venience with the monkey, for he would sometimes reach 

 over the hand containing the pink ball in order to obtain 

 the white one. Most of these experiments were performed 

 with the Capuchins, but some of them were made with
