Dressing and Undressing Experiments. 81 



The pulse- rate as recorded by the subject during the 3 hours of the rest 

 experiment was as follows: 2 h 05 m p.m., 86; 2 h 30 m p.m., 80; 3 p.m., 80; 

 3 b 35 m p.m., 74; 4 p.m., 68; 4 h 35 m p.m., 69; 5 h 05 m p.m., 69. The sub- 

 lingual body-temperatures taken at the beginning and end of the 3-hour 

 experiment and the subsequent 1-hour period were as follows : 2 h 22 m p. m., 

 99.0 F.; 5 h 22 m p.m., 98.3 F.; 6 h 22 m p.m., 98.8 F. The results of the 

 metabolism as obtained for the 3 hours of rest and the 1 hour of activity are 

 given in table 44. 



METABOLISM EXPERIMENT No. 160. 



Subject, F. E. R., February 25, 1905. Age, 20 years 5 months; 

 height, 168 cm.; weight without clothing, 52.9 kilos. 



The subject entered the calorimeter chamber at about 8 a. m., after a break- 

 fast of oatmeal with milk and sugar, coffee with cream and sugar, and water, 

 and was weighed at 8 h 02 m a. m. The experiment began at 9 a. m., and during 

 the greater part of the 3 hours following the subject was occupied in writing. 

 At 9 h 06 m a. m. he went to the food aperture. The undressing period was 

 from 12 noon to 1 p. m. During this period the subject's activity was prac- 

 tically the same as that of the subjects of the two previous experiments. The 

 length of time he was without clothing was 3 minutes. 



The pulse-rate as taken by the subject was as follows : 8 h 12 m a. m., 99 ; 

 9 h 20 m a. m., 94 ; 9 h 39 m a. m., 97 ; 10 h 02 m a. m., 86 ; 10 h 35 m a. m., 82 ; 11 a. m., 

 88 ; ll h 23 m a. m., 88 ; 12 h 03 m p. m., 90 ; 12 h 33 m p. m., 108 ; 1 p. m., 94. The 

 sublingual body-temperatures were as follows: 9 a.m., 99.3 F. ; 12 noon, 

 99.2 F.; 1 p.m., 99.5 F. The results of the metabolism for both the rest 

 period and the undressing period are given in table 44. 



METABOLISM EXPERIMENT No. 161. 



Subject, F. N. C, February 25, 1905. Age, 19 years 1 month; 

 height, 168 cm.; weight without clothing, 57.4 kilos. 



The subject entered the respiration chamber after a dinner consisting of 

 corn beef, potato, corn fritters, and a piece of jelly cake. He was weighed at 

 l h 20 m p. m. and the experiment began at 2 p. m. The first 3 hours of the 

 experiment was spent for the most part in writing plain copying. At 2 h 03 m 

 p. m. and at 4 h 44 m p. m. the subject went to the food aperture. The undress- 

 ing period was from 5 p. m. to 6 p. m., and the subject followed the same 

 routine of activity during this time as was followed by the preceding subjects 

 in this series. 



The pulse-rate for the 3 hours of the rest experiment as recorded at inter- 

 vals by the subject was as follows : 2 h 03 m p. m., 72 ; 2 h 30 m p. m., 72 ; 3 p. m., 

 64; 3 h 30 m p.m., 70; 4 h 15 m p.m., 70; 4 h 30 m p.m., 62: 4 h 55 m p.m., 64. 

 The sublingual body-temperature for the beginning and end of the 3-hour 

 and 1-hour periods was as follows : 2 p. m., 97.8 F. ; 5 p. m., 97.5 F. ; 6 p. m., 

 97.9 F. The results of the metabolism are given in table 44.
