240 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



ject was fairly thin at the beginning of the study. The minimum 

 is again found with Pec, i. e., 3.2 cm., while the average loss for the 

 whole group is 5.1 cm. 



The maximum loss for P, the girth at the perineum, occurred with 

 Spe, 6.7 cm., while the minimum is with Gul, 2.6 cm. The average 

 for the group is 4.6 cm. The largest loss in the circumference at the 

 hips and buttocks, Q, is again found with Spe, with a decrease of 6.0 

 cm., and the minimum with Tom, with a loss of 2.5 cm. The average 

 for the group is 4.3 cm. 



When averaged somewhat arbitrarily, the losses in the five main 

 circumferences for the whole group show a maximum loss with Spe 

 of 6.2 cm., followed closely by Can, with 5.8 cm., with a minimum 

 for Pec, the highly trained athlete, of 3.6 cm. The average for the 

 group is 4.4 cm. 



While in general many of the measurements show decreases roughly 

 approximate to the percentage loss in body-weight, in certain instances 

 the decrease is quite contrary to the percentage loss in body-weight. 

 This is particularly true of the measurement N with Tom, this subject 

 showing a larger decrease in this measurement than any other subject, 

 although he had the smallest body-weight and his percentage loss in 

 body-weight was the smallest. From a general inspection of the data 

 no striking uniformity appears. Apparently no simple mathematical 

 relationship between the decreases in girth and either the total loss or 

 the percentage loss in body-weight may be estabhshed. 



The period of loss in weight for Squad B was approximately 21 

 days. The losses in weight and in the five major girths during this 

 period with these subjects are also given in table 17, together 

 with the initial body-weight and percentage loss in weight. While 

 a direct comparison of these losses is hardly justifiable, since the 

 men were not of the same general contour, yet it is evident that the 

 decreases are less than those found for Squad A. The final per- 

 centage loss in body-weight for this squad was but 6.5 per cent, as com- 

 pared with 10.7 per cent with Squad A. If we take as a general 

 index of decrease in these measurements the averages of the values 

 for G, M, N, P, and Q, we find that they range from a maximum 

 of 5.3 cm. with Liv, to a minimum of 2.3 cm. for Tho, the average for 

 the whole group being 3.4 cm. This is perceptibly smaller than the 

 average for Squad A, which was 4.4 cm. 



The degree of emaciation produced by the restriction in diet may 

 also be shown to some extent by means of the profile photographs 

 given in figures 74 to 85. These were taken of the men in Squad A 

 at the end of the experiment, i. e., on February 2, 1918. For com- 

 parison, a photograph is also given of one subject (Can) which was 

 taken on September 29, before the restriction in diet began. A loss in 

 weight of 10 per cent or even, as with Can, 13 per cent, does not of
