A second experiment was carried ont with a group of thirty-four sum- 

 mer-session miiversitY students, in which the same letter-letter associates 

 were used as in the previous experiment, and in which the quantit}^ of 

 work done instead of the time was kept constant. During the first prac- 

 tice period 120 associations were made with each pair. Four weeks later 

 80 more associations were made with each pair. Just before tlie second 

 practice period the amount that could be recalled during 200 seconds was 

 measured, the amount being the number of correct associates that were 

 recalled when the stimulus letters were read in varied order two seconds 

 apart. The results are given in tables III and IV.
