650 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



since these exercise records supply evidence, first, as to the relative 

 activities of Squads A and B, and second, and perhaps more important, 

 the relative activities between Squads A and B and a group of under- 

 graduates not on restricted diet of any form. The observations on 

 general health and condition of the bowels, which for the most part 

 presented no particular phases, are omitted. 



The blank furnished each of the men called for a subdivision of the 

 hours per day spent in lying, sitting, and walking ; an effort was made 

 to difTerentiate the activity further by the inclusion of a record of 

 exercise of greater intensity than walking. The time spent in lying 

 obviously included that spent in bed, together with any other time 

 that was so occupied, and does not necessarily mean the time asleep. 

 The sitting involves sitting in the men's rooms, in class, at meal times, 

 etc.
