BODY-WEIGHT.

the men left college and other duties prevented most of the remaining 

 subjects from volunteering. Furthermore, the members of the Labo- 

 ratory staff were fully occupied in completing the tabulations and anal- 

 yses of the material in the major research. We have, therefore, only 

 the records of the normal increments in body-weight in the subsequent 

 period of recuperation. The balance used during the diet experiment, 

 which had been carefully calibrated by the Nutrition Laboratory, 

 remained at Springfield for several months after the research was 

 completed. The men were requested to weigh themselves upon the 

 balance from time to time during the spring. The usual normal con- 

 ditions were observed, namely, the weighings were made with the 

 subject in a post-absorptive condition, immediately after passing 

 urine, nude, and the first thing in the morning. We were particularly 

 fortunate in having the cooperation of one of the subjects^ Mr. Ronald 

 T. Veal, who personally superintended these post-diet weighings. 



In the discussion of the individual body-weight curves, attention 

 has already been called to the enormous gains in weight of practically 

 every member of the squad after the experiment was concluded. These 

 increments have been collected in table 12, together with the initial 



Table 12. — Increase in body-weight after resumption of normal diet, Squad A.

weights, the minimum weights during the period of reduced diet, the 

 weights at the end of the period of reduced diet (February 3), and the 

 last weights plotted on the charts (March 14). In the last three 

 columns of the table are given, respectively, the increases on March 14 

 above the weights of February 3, the increases above the minimum 

 weights, and the actual increases above the initial weights in the fall.
