given a table of the results of the trials of the next three days for 

 this raccoon. The trials are henceforth divided into series of thirty 

 each. The food glass was OYS 1.

 Raccoon No. 2. 



The behavior of Raccoon ISTo. 3 toward the same series of colors 

 was not unlike that of ISTo. 2. The first day on which the former was 

 tried with closed glasses he made 55 per cent of right choices. He 

 seemed to learn more slowly than 'Eo. 2, but throughout the records 

 there is evidence that the effects of previous training persisted longer 

 with him. Hence later tables show that he made better records on 

 new colors than did l^o. 2. The record of his choices for the second 

 and succeeding days appears in Table 7. OYS 1 was the food- 

 color, and in other respects the table is like the preceding one.
