256 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



winter of 1917-18 he had to wear heavy all-wool underwear. He noticed his 

 feet and hands were particularly cold. His roommate, who was not a member 

 of Squad A, wore light underwear as usual. 



Gar had worn light underwear during the winter for 4 or 5 years. During 

 that time he had not noticed the cold particularly. During the winter of 

 1917-18 he wore medium-weight union suits, half wool and half cotton, with 

 full-length sleeves and ankle-length legs. His roommate, who was not on the 

 squad, wore no heavier underwear than usual. 



Gul stated that he had worn no underwear since the experiment began. He 

 found it especially difficult to reduce his weight 10 per cent, and believed that 

 if he wore no underwear the radiation of heat would be more rapid. Usually 

 he wore light underwear in the summer and heavy underwear in the winter. 

 During the intense cold of 1917-18 his shins felt very cold when the wind came 

 in between his socks and trousers. When he first came to Massachusetts from 

 North Dakota, a few years before, he did not feel the cold, because the winters 

 in North Dakota are more severe than in Massachusetts. He thought he had 

 not suffered from the cold more during the experiment than in the preceding 

 winter. He wore underwear during the previous winter and had had two 

 colds, the cause for which was not evident. During the winter of 1917-18 he 

 had had no colds. It is a surprising fact that although the other subjects 

 showed great sensitiveness to cold, this man was able to wear absolutely no 

 underwear during the unusually severe winter and with a low diet. This is in 

 striking contrast to the experience of practically all of the other members of 

 the squad. 



Vea, for the previous 4 years, had worn light underwear throughout the 

 whole winter. During the winter of 1917-18 he wore cotton and light-weight 

 woolen underwear, with long sleeves and legs of ankle length. For his walks 

 outdoors, he put on woolen socks. During the last two weeks of the experiment 

 he wore a basket-ball shirt under his regular shirt, in addition to the under- 

 clothes. The overcoat worn during the winter was lighter than usual. 



Can had usually worn two-piece light-weight underclothes, but during the 

 experiment he wore a knitted sweater and heavier drawers and socks than 

 ordinarily. At times he put extra blankets on the bed to keep warm at night. 



Tom, although not actually suffering from the cold, had felt cold and found 

 his tendency was to stay indoors more. He slept in his bath-robe many 

 times and kept moving when out of doors. It was his usual habit to wear the 

 same weight of clothing throughout the year, with the exception of an overcoat 

 in winter. During the experiment he wore no heavier underclothing or socks 

 than usual. His chief difficulty was in keeping warm at night. Although he 

 used an extra pair of blankets, besides his bath-robe, he was unable to keep 

 warm in bed. 



Pec reported special difficulty in keeping warm. On going to bed he could 

 not get to sleep for half an hour on account of the cold. Hfe usually wore a 

 union suit of medium weight, but during the winter of 1917-18 he wore the 

 best and heaviest woolen underwear that he could buy. He also wore a very 

 heavy sweater every day in addition to his regular clothing while in the class 

 room and the heaviest woolen socks that he could purchase, 



Moy dressed more warmly than usual. For the previous 5 years he had 

 worn light underwear throughout the winter. In November, when the 

 weather became colder, he felt cold and put on union suits, knee-length, with 

 short sleeves and of medium weight, but not all wool; no heavier socks were 

 used. In the extreme cold weather he wore a sleeveless basket-ball sweater 

 over his underclothes a part of the time. He also put more blankets on his 

 bed. His overcoat was heavier than that worn the preceding year.
