success is represented by the absence of any column. Thus 

 the first record reads, "No. i with signal 104 after 40 days 



made 5 failures, then 2

record (106 ; 40 days) 

 reads, " perfect success 

 in ten trials."

DISCUSSION OF RE- 

 SULTS 



The results of all 

 these discrimination 

 experiments emphasize 

 the rapidity of forma- 

 tion of associations 

 amongst the monkeys, 

 which appeared in their 

 behavior toward the 



mechanisms. The suddenness of the change in many cases 

 is immediately suggestive of human performances. If all 

 the records were like c, f, h, i, j, k, 1, m, B, E, and memory 

 trials 103, A, B, and C, one would have to credit the animals 

 with either marvelous rapidity in forming associations of 

 the purely animal sort or concede that from all the objective 

 evidence at hand they were shown to learn as human beings 

 would. One would have to suppose that they had clear
