682 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



September 1917. Of Squad A, 9 men were from the senior class, but 

 Fre should not be counted in any comparison, since he served in the 

 squad so short a time; there are thus 8 men whose records are com- 

 parable. Of these, 4 {Can, Gul, Pec, and Vea) show average marks for 

 the diet period which are slightly below their average for all courses 

 preceding September 1917. There are 4 {Bro, Gar, Moy, and Tom) 

 who show marks as good or better for the diet period. Changes are 

 not large in any case, the largest is one of 4 per cent in the case of Moy, 

 whose previous average grade was 87 and whose average grade during 

 the low diet was 91. The whole group of 8 senior subjects taken 

 together show average grades which are identical for both periods, 

 that is, 88.6 per cent. There were 31 other men in the senior class. 

 The average grade for all of these men, prior to September 1917, was 

 86.3 per cent, and for the same group, during the period of the experi- 

 ment, the average was 84.3 per cent. There was thus an average

decrement of 2 per cent for those who were not subjects. If this ten- 

 dency of the class as a whole during the first two terms of this year as 

 compared to the record for previous years is contrasted with the aver- 

 age record for the 8 senior men who were subjects in Squad A, it is 

 perfectly justifiable to say that these men did not do work that was 

 inferior to their previous college work, and their performance was in 

 no way below that of their fellows. Three of the subjects of Squad A 

 were classified as sophomores; these were Mon, Pea, and Spe, as
