VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



is 217 a, with an average individual variability of 20.5 per cent. With 

 Squad B the general average for the 3 normal experiments is 224 cr, 

 with like variability of 20.5 per cent. The average for the 2 low-diet 

 experiments is 206 a, with a variability of 19 per cent. The averages and 

 variabilities for the individual subjects are not particularly noteworthy. 

 There were no normal eye-reaction experiments for Squad A. The 

 total number of these measurements was further reduced by the tread- 

 mill experiments on January 6 and 28 with Squad B, and on February 

 3 with Squad A, and the standard electrocardiograms on December 20 

 with Squad A, as on all four dates the morning psychological program 

 had to be omitted.^ 



The available data for Squads A and B are plotted in figure 112. 

 The two upper curves are for the variability and they show about 20 

 per cent for both squads in the first two experiments. In the third 

 experiment with each squad there was a definite increase which, with 

 Squad A, was to about 25 per cent. As seen in table 167, several men 

 in Squad A showed unusually high variabilities in that experiment, as, 

 for example: 34.5, 34.6, and 37 for Kon, Pec, and Tom. These values 

 are high enough to account for this fluctuation. With Squad B the 

 percentage for the third experiment was 21.7. This is not a large 



^The fragmentary data for Squad A on November 11 are due to a technical difficulty in the 

 apparatus; the subjects were in no way to blame.
