PULSE-RATE.

Table 80. — Daily pulse-rate^ of Squad A — continued. 

 [Subjects in lying position, without food.] 



* These observations were made early in the morning at least 12 hours after the last meal and 



for the most part are averages of a considerable number of pulse-rates taken during 

 the two periods on the respiration apparatus. 



* Records on this date taken in Boston in the group respiration chamber. 



' Note that for these subjects the maximum occurs in January; with the others it appears early 

 in the series. 



during the period with the reduced diet. Comparing the rates pre- 

 vailing at the beginning of the experiment with normal diet and those 

 at the end of January with reduced diet, we find a pronounced fall in 

 pulse-rate in every instance. This striking reduction in pulse-rate is 

 so great with most of the subjects that frequent observations are 

 recorded of pulse-rates between 35 and 40 per minute and even lower. 

 To lay particular emphasis upon the low rates, all values between 40 

 and 36 inclusive are printed in italics, and the values of 35 or below in 

 bold-face type. An inspection of the table shows the incidence of the 

 italicized figures as the study progressed. The members of the squad 

 with whom italicized figures occur increase in number with the length 

 of the period of reduced diet until, in the last week in November, 8 of 

 the squad show values of 40 or below. As a matter of fact this repre- 

 sents the minimum pulse for the squad as a whole. At the end of 

 the experiment, 5 men show values of 40 or below, but the number of 

 low counts is somewhat less than those which appear in the table in the 

 latter part of November. 



Special emphasis should be laid upon the appearance of the bold- 

 face figures indicating 35 counts or below. These are found with 5 

 subjects during the month of November and in the latter part of 

 January. Records of 32 or below appear in 4 cases in November and 

 the absolute minimum was clearly and definitely established with 

 Vea on November 19 of 29 beats, this record being the average of a 

 series of 6 counts. The actual counts for this particular subject on 

 November 19 were: 30, 29, 29, 28, 29, and 30. Thus we have
