Leaving a few deviations out of consideration we can state that

 The tendency of the second interval to decrease in relation to the 

 first, which we found vaguely indicated in studying the tables relating 

 to the I'hythm of the first repetition, is thus seen to maintain itself 

 all through the learning- process. 



With I the data yielded by the repetition-experiments present the

 the material induces a progressive increase of the time falling to 

 every syllable of the groups 1, 2 and 3 for M, to those of groups 

 1 and 2 for R. The time- values for D that formed an exception
