EXERCISE RECORDS FOR SQUAD B. 



Squad B, having been put upon restricted diet on January 8, kept 

 records of their activity similar to those of Squad A in the period from 

 January 10 to 29, inclusive. An examination of the detailed figures, 

 table 1^5, shows that in general the men were in bed about 8 hours a 

 day. The hours recorded for sitting vary considerably for the different 

 men, ranging from 6f to 12f , but usually are not far from 9 to 10. The 

 hours spent in walking are reasonably uniform, from 4 to 5 hours, 

 while the exercise more strenuous than walking varies considerably, 

 the majority of the men indicating not more than 1 or 2 hours. There 

 is a striking exception in the case of Fis (4f hours) .
