to C. The second interval evinces, here also, a tendency to decrease. 

 Anyhow, with R it is, as a rule, smaller than the first. 



Whereas in the learning-experiments with II we could hardly 

 distinguish a regular increase of the mean time falling to one 

 syllable of tlie several groups, in the repetition-experiments there is 

 even a tendency to decrease from A to C. 



Whereas with M the time-values for A, B and C are still about 

 equal, with R we see already a tendency to decrease, and with D 

 this tendency comes to the front unmistakably (only one exception). 

 The decrease from 1 to 3 continues regularly; only D presents an 

 exception. 



The intervals in the repetition experiments with II increase 

 regularly for R and D from A to C, for M they remain about 

 constant. With R the second interval is always smaller than the 

 first, with D it is always greater.
