 the other hand, the curve for Tho, who was even more deficient in 

 weight, shows a very rapid fall as a result of the restriction in diet. 



LOSSES IN BODY-WEIGHT DUE TO RESTRICTION IN DIET. 



The losses in body-weight of Squads A and B are recorded in table 

 11. In interpreting this table it should be recalled that Squad B was 

 subsisting upon a uniform diet of approximately 1,400 net calories, 

 i. e., all the men received practically the same amount, while the diet 

 for the members of Squad A varied. The absolute losses for the men 

 are not, however, so significant as the percentage losses, and these 

 are also given for both squads in table 11. 



For Squad A two low values have been calculated : First, the abso- 

 lute minimum for the entire period of observation, and second, the 

 weight observed at the conclusion of the experiment. The greatest 

 loss experienced with Squad A is recorded in column d, in kilograms, 

 and the percentage loss, as compared with the initial weight, in column 

 e. The values in column d were given in table 9, and have already 

 been discussed in that connection. The greatest percentage loss was 

 that found for Can of 13.8 per cent, although two others {Mon and 

 Pea) showed a percentage loss of 13.5 and 13.4 per cent, respectively. 

 The smallest loss was that found for Tom of 8.7 per cent. The average 

 maximum loss for the entire squad was 12.1 per cent. 



When we examine the final weights for Squad A, we find that none 

 of the men retained their maximum loss at the end of the experiment, 

 but that all increased in weight slightly, although the increase for 

 Vea was only 0.2 kg. The greatest loss at the end of the test was 

 still sliown by Can, with a percentage loss of 13.2 per cent. The mini-
