each have 124 for pulse-cycle length corresponding with a rate per 

 minute of 48 beats. The pulse-cycle length during activity shows a 

 range from 65 to 95 for Tom and Vea, respectively. It is worthy of 

 note that Vea, whose pulse has been spoken of in other connections 

 (see p. 387) as so remarkably low, showed a cycle-length during activity 

 considerably longer than that of Pec and Pea, whose quiet pulse length 

 was at the same level with Vea. On the other hand, Pea and Pec 

 show greater changes between activity and the subsequent rest than 

 does Vea. The resting level ranges from 67 to 99 for Tom and Pea, 

 respectively. In terms of per cent the activity is from 61.4 to 76.6 

 {Gar and Vea) of the quiet pulse-cycle length and the resting percentage 

 is from 65.6 to 89.6 with Gar and Mon, the latter demonstrating unus- 

 ally quick recovery in pulse-cycle length following the activit}' . 



For Squad B records were taken on two normal dates, November 

 18 and December 16, and on two of the low-diet dates, January 14 

 and January 20. (See table 95.) The averages at the right-hand 

 of the table do not include the values for McM, Kim, and Sch. The 

 other 10 men show averages for November 18 of 94, 67, and 70, for 

 conditions of quiet, activity, and rest, respectively. In per cent of the 

 pulse-cycle length during quiet, the activity and rest are 71.3 and 

 74.2, respectively. The average pulse-cycle length for the two nor-
