Table 95. — Different levels of pulse-cycle length udth conditions of quiet, activity, and rest for men of Sqxiad B. 



[Values in 0.01 second for pulse-cycle length.] 



mal dates and for the three conditions in the records, as shown in the 

 right-hand column of table 95, are 92, 67 and 70, the latter two values 

 being 72.8 and 76.1 per cent, respectively, of the pulse-cycle length 

 during quiet. The individual subjects show no marked peculiarity, 

 except in the comparison of the pulse-cycle lengths for activity and 

 rest. During the 20 beats in the rest following the activity five of the 

 subjects, Fis, How, Lon, Liv, and Wil, have pulse-cycles as short as or . 

 shorter than during the activity. In other words, after the activity the 

 pulse tended to remain high for a period. Thus we have a difference 

 between the conditions of activity and rest (72.8 and 76.1) of only 3.3 

 per cent in the case of Squad B, while with Squad A the resting pulse- 

 cycle length was 7.4 per cent longer than the cycle length during 

 activity. In the average for the two low-diet experiments, several 

 Squad B men show the same condition, that is, a faster pulse following 

 the activity. Hence it can not be assumed that the contrast between 

 the normal of Squad B and the records of Squad A is due to the reduced 

 diet. 



The average quiet, activity, and rest values with the percentage of 

 change from the quiet as shown by activity and rest are, for com-
