maximum of 81 mm. on October 13 and a minimum of 63 mm. on 

 January 26, a total fall of 18 mm. It is important to note that the 

 average values for 11 men on January 26 and February 2 are 63 and 

 64 mm., respectively. 



SYSTOLIC AND DIASTOLIC BLOOD PRESSURE. SQUAD B. 



Since we have no basal data for the men in Squad A, i. e., measure- 

 ments prior to dietetic restriction, the values found for Squad B have 

 a special interest, as observations were made with these men the night 

 preceding the beginning of their dietetic restriction (January 5, 1918). 

 The data obtained for Squad B on January 5 and on the subsequent 



1 All blood-pressure measurements were taken with the Tycos sphygmomanometer, with the 



subject sitting. 

 * Blood-pressure measurements were obtained with McM on Jan. 5, as follows: Systolic, 110; 



diastolic, 75; pulse pressure, 35. 



nights, January 13, 19, and 27, 1918, are given in table 77. The 

 normal values for systoUc pressure obtained on January 5 ranged 

 from 105 mm. with Kim, Tho, and Wil, to a maximum of 142 mm. 

 with Sch. The average systoUc pressure for the 11 men was 120 mm. 

 The diastoUc pressure for this date ranged from 75 mm. with Tho, 

 to 90 mm. with Fis, Sch, and Van. The average diastoUc pressure 

 for the 11 men on this day was 83 mm. 



One week later (January 13) the systolic pressure had fallen in every 

 case, with the single exception of Kim, with whom there was an in-
