258 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



SQUAD B. 



Fis, while on low diet, wore the same clothing as usual, with heavy under- 

 wear, but was more sensitive to the cold than ordinarily. Endured the cold 

 better after the experiment was over. 



Har, during low diet, wore a sweater under his coat most of the time, particu- 

 larly when out of doors. Felt the cold considerably, even with this extra 

 clothing. After the experiment was over he was not cold and did not wear the 

 sweater. 



How said that since the experiment he did not notice the cold, this being the 

 greatest difference between the low-diet period and full diet. No change in 

 clothing or bedding. His room was warm, steam-heated. During low diet, 

 felt the cold keenly, but did not change clothing at all. At a dance during 

 the diet period, he was surprised that he did not perspire as usual. 



Ham did not notice the cold when on low diet. Had worn the same weight 

 of clothing all the time. 



Kim felt the cold during the low diet but wore clothing as usual; more bed 

 clothing at night, and had continued to use it, but did not feel the cold so 

 much. 



Lon had not noticed the sensation of cold so much since the end of the 

 experiment. Wore heavier clothes during the low-diet period, including a 

 regular woolen sweat-shirt over his undershirt, but on full diet found it too 

 heavy. He wore woolen socks during the low-diet period and for three days 

 after the experiment. 



Sch, during the diet period, could not perspire; felt the cold keenly in the 

 hands and feet only. On subsequent full diet did not feel the cold. Was sure 

 that this was not due to change in weather, but thought he could endure colder 

 weather with full diet. No change in weight of clothing. 



Tho felt the cold very much when on the low diet; sometimes wore an extra 

 sweater during experiment; otherwise no change in clothing. 



Van, when on low diet, was cold, required much exercise to warm up, and 

 could not induce perspiration. After full diet was resumed was not cold, 

 required only a little exercise to warm up, and perspired easily. ''During this 

 cold weather, I naturally feel the cold, but there is a difference between the 

 way it feels now and when on the diet." 



All of the men in Squad A showed a marked disinclination to swim 

 in the natatorium in Springfield as the experiment continued ; a number 

 of them found it so uncomfortable that the instructor was obliged 

 to excuse them. On the day that the series of motion pictures was 

 taken, February 1, 1918, the men were very much opposed to swim- 

 ming until it was found that the water was unusually warm. Some 

 of the men regularly instructed classes in swimming; in the latter 

 part of the experiment these men did not go into the water at all, but 

 instructed from the platform. After the return to the regular diet 

 the subjects entered into the swimming with much enjoyment. This 

 reluctance to go in swimming was not shown by the men in Squad B, 

 even during the third week of the diet restriction; at least they made 

 no comments on it. 



During the endurance test, when the subjects held their arms ex- 

 tended horizontally for nearly an hour, it was noted that the hands 

 became very blue, and several of the men reported that they suffered
