392 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



On December 9 in Boston the pulse-rate averaged 47, the day before 

 in Springfield 44, and the following day, also in Springfield, 50. On 

 December 20 the rate obtained in Boston was 44 and the day before 

 43. On January 13 the rate in Boston was 48, the day before 52, 

 and the following day 50. On January 27 the average rate in Boston 

 was 42, the day before 42, but the following day, only 38. This last 

 average is made up of values obtained from only 4 men, three of whom 

 had consistently low pulse-rates. The final value for February 3 of 

 45 is the same as that for February 2 obtained in Springfield. The 

 somewhat different conditions obtaining in the Boston experiments 

 (see p. 491) were thus not sufficient to affect materially in either 

 direction the average pulse-rates. It therefore seems perfectly justi- 

 fiable to include them among the average pulse-rates in table 80. 



BASAL PULSE-RATE WITH LYING POSITION. SQUAD B. 



Basal pulse-rates were also obtained for Squad B in the group respira- 

 tion chamber in Boston, both for the normal period and during re- 

 striction in diet. They find subsequent use in a comparison of the 

 positions of lying and standing on page 413. Although fewer in 

 number than those of Squad A, they deserve presentation here, and 

 are recorded in table 82. It will be seen that on two days the sub-

jects were with normal diet, although January 6 is characteristic of 

 being the first observation after the Christmas recess. It may not 

 be without significance that the average pulse-rate of this group showed 

 an increase of 3 beats on the return of the men from the Christmas 

 recess; it will be recalled that a pronounced increase was also found 

 with Squad A under these conditions. Of special significance, how- 

 ever, are the values found on the three subsequent days with reduced
