the normal and 7.6 for the low diet. With the exception of Liv, Wil, 

 and Fis, all the 10 regular subjects show better scores for the low-diet 

 period than during the normal sessions, that is, the improvement con- 

 tinued during the reduction in diet. 



The relation between the scores of the two groups and the food re- 

 duction period is brought out best in figure 106. Both curves show a 

 tendency to improvement; Squad B is somewhat above A at the 

 beginning and in four of the other sessions. In the fourth session they

 B dropped below. The fluctuations are rather large with both squads. 

 Squad B shows a falling off on November 17 and December 15, but 

 good results on January 5, i. e., just after the vacation, a date that 

 shows poorly in several measurements. On January 13, their first 

 low-diet session, they have the best average of the whole experiment in 

 marked contrast to low-diet dates January 19 and January 27. Squad 

 A demonstrates a large amount of variability in the early part of the
