remains remarkably constant at 58. From January 7 to 20 this level 

 rises to 64, but again falls to 58 in the last period of the observations. 

 From tables 89 and 91, therefore, while something can be inferred 

 regarding the influence of reduced diet upon the pulse-rate, evidently 

 averages obtained in this way for long periods will not suffice for a clear 

 analysis, and a better idea may be obtained from a graphic represen- 

 tation of the individual values. Such representation is given in figure 

 91, (p. 411) in which the curves for the lying and sitting values obtained 

 with Squad A are compared with each other. 



Pulse Records at Meal Times, Squad B. 



The pulse data taken at meal times for Squad B in this series have 

 a significance not found with those for Squad A, as with the second 

 squad the counts were made with both normal and low diet. It is 

 unnecessary here to give in detail the individual measurements reported 

 by Mr. Davis, but the differences between the pulse values during 

 October, November, and December and those for the January period 

 have a special interest, as those for the first three months were obtained 

 under normal diet conditions, while most of those recorded in January 

 were with the low diet. With Squad B pulse counts were made not only 

 at the noon and night meals, but likewise during the morning meals, 

 and hence a direct comparison may be made of the morning, noon and 

 night values. This comparison is made in table 92. Inasmuch as the 

 subjects were on normal diet until January 8, we find a reasonable 

 uniformity in the values. The normal morning pulse-rate averaged 63, 

 the noon pulse 72, and the night 68. With the beginning of the reduced 

 diet, however, a noticeable fall in the pulse-rate is found with the entire 

 group, and the three average values recorded beginning January 8 are 

 on a definitely lower level than any of the earlier records. The average 

 for the morning records during the low-diet period from January 8 to
