56 Metabolism of Healthy Man. 



The pulse and respiration were recorded by the pneumograph and are given 

 in table 22. 



The rectal body-temperature taken with an electrical-resistance thermometer 

 was at 9 h 15 m a. m., 36.4.0 C. ; at ll h 15 m a. m. it was 36.76 C. During 

 this period the water vaporized was 59.4 grams, the carbon dioxide eliminated 

 was 58.7 grams, and the oxygen absorbed 51.8 grams. The heat elimination was 

 173.3 calories, and the heat production 194.4 calories. 



METABOLISM EXPERIMENT No. 136. 



Subject, F. G. B., October 23, 1905. Age, 35 years; height, 

 183 cm.; weight without clothing, 83.2 kilos. 



The subject (a chemist) entered the chamber at 4 p. m. No record was made 

 of the food eaten at the last meal. The first period began at 5 h 46 m p. m., and 

 previous to this the subject sat quietly in the chair most of the time. The 

 experiment continued until 9 h 46 m p. m., the measurements being made in two 

 2-hour periods. At 5 h 52 m p. m., the subject drank about 100 c. c. of water. 

 At 7 p. m. he passed urine. At 7 h 05 m p. m. he went to the food aperture and 

 received his lunch, which consisted of 450 grams of milk, 4 slices of entire 

 wheat bread with butter, and 75 c. c. of water. He began to eat immediately 

 and while eating telephoned a number of times, and there was more or less 

 muscular movement. The first period ended at 7 h 51 m p. m. During the 

 second period the subject was comparatively quiet, reading most of the time. 

 He drank about 150 c. c. of water at 8 h 30 m p. m. The comment made by the 

 subject was that he was slightly irritated by the presence of formaldehyde, 

 which had been used for disinfecting the chamber some time before. 



The pulse-rate as recorded by the subject was as follows: 4 h 04 m p. m., 84; 

 4 h 50 m p.m., 88; 6 p.m., 76; 6 h 30 m p.m., 75; 7 p.m., 73; 7 h 50 m p.m., 70; 

 8 h 25 m p.m., 73; 8 h 56 m p.m., 73; 9 h 38 m p.m., 70. The sublingual body- 

 temperatures recorded by the subject were as follows: 5 h 44 m p. m., 98.6 F. ; 

 7 h 50 m p.m., 98.5 F.; 9 h 48 m p.m., 97.8 F. The results of the metabolism 

 in the two periods are given in table 44. 



METABOLISM EXPERIMENT No. 137. 



Subject, A. H. M., November 13-14, 1905. Age, 24 years 1 month; 

 height, 179 cm.; weight without clothing, 61.7 kilos. 



This experiment was planned to determine whether it was possible for a 

 man to remain in the calorimeter over night without suffering any ill effects 

 from his sojourn. Previous to this experiment the subject, a student, had 

 been in the calorimeter and had become sick as a result of mercurial poisoning. 

 The experiment in which the subject became ill and the experiment here 

 reported have both been briefly reported by us in a previous publication. 1 The 

 subject entered the respiration chamber at about 3 p. m., and the measure- 

 ments began at 5 p. m. Immediately after the beginning of the first period 

 the subject was weighed in the chair and then the bed-clothing, which he had
