 unusually long "and Irregular, This irregularity is 



most pronounced in the early trials before the rapid 

 descent in the curves is made, though it is prominent 

 in the curve of five trials up to the 100th trial. The 

 descent in the curve for five trials takes place in the 

 27th, for three trials in the 32nd, and for one trial in 

 the 11th trial. Where there is slowness in descent 

 and more or less irregularity, there exists a retarda- 

 tion in learning. Curve shows that retention is best 

 for five trials, and poorest for three trials,which is 

 just the reverse in the retention test of the latch box. 

 Before leaving the discussion of the maze, it would 

 be veil to compare the results obtained from the latch 

 box with those of the maze. In both cases learning 

 when distributed over several days is apparently most 

 economical. This particular point will be reserved 

 for later discussion but it is of peculiar interest 

 at this time to compare the curves of both. They all
