40 Metabolism of Healthy Man. 



METABOLISM EXPERIMENT No. 111. 



Subject, C. F. B., January 18, 1905. Age, 16 years 7 months; 

 height, 170 cm.; weight without clothing, 62.2 kilos. 



This experiment was the first of a series begun to study the normal metab- 

 olism of men of different ages resting quietly during varying periods of the 

 day. No attempt was made to eliminate the effect of the ingestion of food 

 and hence, in nearly all the experiments, food was taken prior to or during the 

 experiment. 



The subject was an assistant in the laboratory and was therefore familiar 

 with the routine of the experiments. He entered the respiration chamber in 

 the forenoon and the experiment began at l h 40 m p. m. No food was taken after 

 the breakfast in the early morning. During the greater portion of the time 

 the subject remained sitting quietly in an arm-chair reading, although he left 

 the arm-chair twice, went to the food aperture, and took out a bottle of water. 

 The experiment ended at 5 h 40 m p. m. During the experiment the subject 

 drank 218 c. c. of water and passed 647 grams of urine. Analyses of the urine 

 were not made and no observations were made of the pulse and bod}^-tempera- 

 ture. As this was the first experiment with this subject and the first of this 

 type in the calorimeter, but one 4-hour period was made. The results of the 

 metabolism are given in table 44. 



METABOLISM EXPERIMENT No. 112. 



Subject, T. M. C, February 13, 1905. Age, 26 years 5 months; 

 height, 166 cm.; weight without clothing, 50.7 kilos. 



The subject (a chemist) entered the respiration chamber shortly after 

 dinner, which consisted of 3 boiled eggs, 2 rolls and butter, ^ pint of cream, 

 and 1 cup of cocoa, with 2 teaspoonfuls of sugar. The subject entered the 

 chamber and was weighed at l h 15 m p. m. He felt very warm, owing to the 

 hot cocoa, and so removed his coat. The experiment proper began at 2 h 06 m 

 p. m. and continued until 6 h 06 m p. m., subdivided into two 2-hour periods. 

 At 4 h 30 m p. m. the subject rose, opened the food aperture, and sat down again. 

 Although never having served as a subject in the respiration chamber before, he 

 was perfectly familiar with the apparatus and experienced no abnormal sensa- 

 tions as a result of the experiment. 



The pulse-rate recorded by the subject was as follows: 3 h ll m p.m., 88; 

 4 h 00 m p.m., 82; 4 h 38 m p.m., 84; 5 h 10 m p.m., 80; 5 h 31 m p.m., 83. The 

 sublingual temperature was 98.6 F. at 3 h 17 m p.m. and 98.6 F. at 6 p.m. 

 The total metabolism as measured on this subject for two 2-hour periods is 

 given in table 44.
