82 Metabolism of Healthy Man. 



METABOLISM EXPERIMENT No. 162. 



Subject, H. C. A., February 27, 1905. Age, 21 years 4 months; 

 height, 172 cm.; weight without clothing, 59.0 kilos. 



The subject (a student) ate breakfast consisting of coffee with milk and 

 sugar, one-half glass of milk, 3 or 4 crackers, and half a dozen graham biscuits 

 with butter before entering the chamber. He was weighed at 8 h 10 a. m. 

 and the experiment began at 8 h 52 a. m. The rest period continued until 

 ll h 52 a. m., the subject occupying most of the time in copying from a report 

 and a magazine. At 8 h 56 a. m. he went to the food aperture, and at 10 h 32 m 

 a. m. and at 10 h 46 a. m. he rose and changed the position of his chair. The 

 undressing period was from ll h 52 m a. m. to 12 h 52 m p. m., and he went through 

 the usual routine for this period. The subject was undressed 5 m 54 s , a some- 

 what longer period then with most of the other men. 



The pulse-rate as recorded by the subject for the whole experiment was as 

 follows: 9 a.m., 69; 9 h 51 ra a.m., 58; 10 h 28 m a.m., 54; 10 h 58 m a.m., 54; 

 ll h 36 m a. m., 48. The sublingual body-temperature was as follows : 8 h 52 m a. m., 

 97.8 F.; ll h 52 m a. m., 97.3 F.; 12 h 52 p. m., 97.6 F. The results of the 

 metabolism are given in table 44. 



METABOLISM EXPERIMENT No. 163. 



Subject, N. M. P., February 27, 1905. Age, 21 years 2 months; 

 height, 179 cm.; weight without clothing, 69.8 kilos. 



The subject entered the respiration chamber about 1 p. m. and soon after- 

 ward had a lunch consisting of 4 chicken sandwiches, 2 cups of cocoa, and 1 

 orange. The rest period began at 2 p. m. and lasted until 5 p. m., during 

 which time he copied material from a magazine and a report. At 2 h 01 m p. m. 

 lie went to the food aperture. During the undressing period from 5 p. m. 

 to 6 p. m., he went through the same routine as did the subjects in similar 

 experiments. He was undressed 2 m 8 s . 



The subject took his own pulse-rate, which was as follows : l h 58 m p. m., 73 ; 

 2 h 35 m p. m., 73 ; 3 h 15 m p. m., 64 ; 3 h 58 m p. m., 62 ; 4 h 57 m p. m., 59 ; 5 h 55 m 

 p. m., 56. The sublingual body-temperature was as follows : 2 p. m., 98.7 F. ; 

 5 p. m., 98.4 F. ; 6 p. m., 98.4 F. The results of the metabolism during the 

 rest period and the undressing period are given in table 44. 



METABOLISM EXPERIMENT No. 164. 



Subject, J. A. R., February 28, 1905. Age, 23 years 7 months; 

 height, 180 cm.; weight without clothing, 59.0 kilos. 



Before entering the chamber the subject had a breakfast consisting of 2.5 

 tablespoonfuls of prepared cereal with milk and sugar and a small slice of 

 graham bread. He was weighed at 8 h 05 m a. m. and the rest period began at 

 9 h 15 m a, m. and lasted until 12 h 15 p. m. At 9 h 22 a. m. he went to the food 

 aperture. During the greater part of this time be was occupied in writing,
