section from one of the tables in Mr. Davis's thesis. This shows the 

 values obtained with Squad A at noon from October 17 to November 

 30. The counts were of course obtained with varying amounts of 

 food in the stomach and after considerable conversation and minor 

 movement, and they may also have been preceded by a somewhat 

 brisk walk to the dining-hall. On the other hand, these irregularities 

 are more or less eliminated in the averages for each day which are 

 recorded at the extreme right in table 88. In considering these 

 records, it should be noted that the actual number of men included 

 in the averages varied but little from day to day. The tendency shown 

 in the records from October 17 to November 30 is for the average 

 pulse to fall somewhat. The absolute minimum average for the squad 

 during this period is 47 on November 24, the average on this day 

 representing the entire squad. 



As a general index of the trend of the averages for the entire period 

 of the test, we reproduce another table from Mr. Davis's thesis which 

 gives average values for periods of approximately 2 weeks for the 

 whole series of noon observations for each subject. (See table 89.)

These averages indicate a fall to a level of 54 during the observations 

 from November 16 to December 19. The high value from January 

 7 to 20 is due to the increase noted with all the men after the return 

 from the Christmas vacation. The values for January 21 to February 

 2 are again at the lower level. None of the observations averaged 

 in this table were obtained during full diet, save for the last two days 

 in November. 



As an illustration of the observations made at the evening meal, the 

 records for October 17 to November 30 are reproduced in table 90,
