animals who required more than three thousand seconds in which 

 to learn the maze pathway. There is a decided apex in the dis- 

 tance curve (Fig. 6-G) at thirty-three thout^and, which nearly 

 corresponds with the group average of thirty-six thousand. 

 Average mean variations for the group were: 



Trials 41 ±17 41,% 



Time 745 ri:in. ±466. min 63^^ 



Distance 367.5 m. ± 12^.^ m 365^ 



Once more the distance variation ia seen to be the least. 



There was almost no difference between the learning of 

 the males and that of the females, such difference being even 

 less marked than in the twenty-five day group. The averages 

 are : 



Both time and distance variation for the males were less 

 than for the females.

Kales 449 min. 109 m.
