The body-weight values for Squad B are collected in table 10, these including the normal weights for age and height (column o) from the Medico-Actuarial Mortality Investigation table, the actual weights on October 7, 1917, when the men first visited Boston, and again on January 6, 1918, just prior to the restriction in diet which began on January 8 (columns b and d). The differences between these records of actual weights and the normal weights for the age and height of the subjects are given in columns c and e. The individual members of Squad B changed slightly as the experiment progressed, Kim and Sch joining the group just prior to diet restriction; no body-weights for these two subjects are therefore given for October 7.

Table 9. - Comparison Of Body-Weights With Normal Standards, Squad A

1 Normal weight based on table 4 in report of the Medico-Actuarial Mortality Investigation, 1912, 1, p. 38, deducting 8 lbs. for clothing.

2 Height obtained Oct. 7, 1917.

3 Weight obtained Oct. 28, 1917; weight on Oct. 7 was 67.3 kg.

Table 10. - Comparison Of Body-Weights With Normal Standards, Squad B

1 Height obtained Jan. 5, 1918; age computed for date of Jan. 5, 1918, and not for Oct. 7, 1917, as with the other subjects. 2 Weight obtained Dec. 16, 1917; Lon did not come to Boston with Squad B on Jan. 6, 1918.

Comparing the differences between the weights on October 7 and January 6 for those who were weighed on the first date, we find that the tendency was for the entire squad to gain in weight during this period, the average for 10 men being 1.25 kg. (see column /). Only one man, Ham, showed a loss, but the difference was insignificant, being but 0.2 kg. The largest increase was that of Liv (3.1 kg.).

The tendency for the men to increase in weight during the first part of the academic year is in accordance with the opinion previously expressed by Professor Berry and others of the college faculty. This normal increase in weight is of special significance here, for it shows that the men in Squad B, when they began the reduced diet in January, were at a perceptibly higher level than if they had taken the low diet early in the fall. In other words, their body-reserves were considerably greater on January 6 than they were on October 7. Unfortunately, the character of these body-reserves is unknown to us. Whether the storage of nitrogen was greater, the difference in weight was chiefly fat, or there was a material increase in the glycogen storage can not be inferred from our data. This remains one of the important problems for future solution. The fact that the general picture exhibited by Squad B as to the total effect of a rapid reduction in diet and weight is essentially the same as that of Squad A is of unusual interest, viewed from the standpoint of normally existing larger body-reserves. But two men in Squad B were distinctly under normal weight on January 6, these being Kim, with a deficiency of 4.4 kg., and Tho, with a deficiency of 4.8 kg. (See column e.) Lon and Har were but little over normal weight. On the other hand, Fis, How, Ham, Sch, Liv, Sne, and Wil were all 4 or more kilograms overweight, the greatest excess weight beinr found with Liv (11.8 kg.).
