All the records of the groups whose learning was in- 

 terrupted showed a saving in that part of the learning 

 which followed the return to the maze already partially 

 learned, except the error-record of the group whose learning 

 was broken into after the eighth trial in the D maze, the 

 trial and error-records of the group whose learning was 

 interrupted after the sixteenth in the D maze, and the 

 trial-record of the group whose learning was interrupted 

 after the sixteenth trial in the E maze. 



The figures in table 44 help to bring out the fact, which 

 has been already stated, that the negative result in the 

 case of time, when the learning of the maze before and 

 after the interruption is compared with the record of the 

 control-group, is due to the small time-records made in 

 the part of the maze-learning succeeding the interruption 

 not being numerous enough to counterbalance the large 

 time-records for the trials before the interruption. 



These figures make plain the basis for the similar observa-
