220 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



Body-weight curve of Spe (Fig. 66). 



Although Spe could not complete the experiment, owing to an un- 

 foreseen and unfortunate illness which necessitated the observations 

 being stopped on December 13, his body-weight curve indicates a 

 consistent regular loss until November 11, when there was the usual

noticeable rise. There was also a rise after the unrestricted meal on 

 November 25, with a tendency for the weight to remain at the lower 

 level of approximately 56 kg. during the period between November 

 11 and December 13. To hold him at this weight it was necessary 

 to increase the calories to approximately 2,250 calories. 

 Body-weight curve of Tom (Fig. 67). 



One of the most sedentary men in the whole squad was Tom, who was 

 under normal weight at the beginning of the experiment. His 

 duties in the college store prevented his taking a large amount of 

 exercise and he found great difficulty in reducing his weight on the diet 

 supplied to the other men. Consequently the fall in the body-weight 

 curve is much slower than with the other subjects. There is, how- 

 ever, the characteristic rise after November 11 and another after 

 November 25, both of these after the unrestricted diet on the Sundays 

 following the Boston experiments. Subsequently, however, until the 

 beginning of the Christmas recess, his body-weight remained essentially 

 constant at about 55.5 kg. During the Christmas recess he was at 

 home and was operated upon for hemorrhoids. He thus underwent
