syllable of a group is much more difficult to reproduce than the 

 others, in consequence of which the tendency to use rhythm inter- 

 feres with reproduction-tendencies of different degree. 



The process of the recitation agrees in another respect with that 

 of the mean duration of the time falling to a syllable of one of the 

 groups, viz. in this that with 1 as well as with II, the mean duration 

 is almost without exception, longer in the learning-experiments than 

 in the repetition-experiments. In a much smaller degree this also 

 applies to the intervals, their duration being in most cases also 

 shorter in the repetition- than in the learning-experiments. 



The mean deviation is for all observers, with I and with II, in 

 the learning- and in the repetition-experiments greater for the in- 

 terval than for the groups, from which follows that here also the 

 rhythm is kept up better for the groups than for the intervals. 



The mean deviation being in the majority of cases smaller with 

 I than with II it would seem that, broadly speaking, the natural 

 method is more favourable than the experimental to an orderly 

 recitation of the learned series. 



CONCLUSIONS. 



1. With only a few exceptions all our observers used rhythm
