44 Metabolism of Healthy Man. 



sisted of 187 grams of oranges, 158 grams of crackers, and 465 grams of milk. 

 With his lunch he drank 438 c. c. of water. During the experiment he passed 

 922 grams of urine and drank a total of 888 c. c. of water. The subject stated 

 that the air seemed close at times and that he had a slight headache, although 

 he felt better during this than in the preceding experiment. He was also 

 unusually active while in the chamber as compared with other experiments. 

 The pulse-rate as recorded by the subject was as follows : 8 h 35 m a. m., 88 ; 

 9 h 15 m a. m., 83 ; 12 noon, 68 ; l h 20 m p. m., 65 ; 3 h 15 m p. m., 70. The body- 

 temperatures were sublingual and as follows: 9 h 17 m a.m., 98.2 F. ; ll h 17 m 

 a. m., 97.8 F.; l h 17 m p. m., 98.1 F. ; 3 h 17 m p. m., 98.3 F. The results of 

 the metabolism in this experiment are given in table 44. 



METABOLISM EXPERIMENT No. 118. 



Subject, B. N., April 29, 1905. Age, 16 years 2 months; 

 height, 168 cm.; weight without clothing, 45.8 kilos. 



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

 fast taken about 1 hour before, consisting of 2 boiled eggs, 1 slice of bread, 

 1 cup of coffee, and 2 crackers. He was weighed at 9 h 04 m a. m., and then 

 sat quietly until the experiment began at 9 h 44 m a. m. The experiment ended 

 at 3 h 44 m p. m., and the measurements were made in three 2-hour periods. 



At the beginning of the first period the subject rose from his chair, went 

 to the food aperture, took out a bottle of water and placed the thermometer 

 in the food aperture, then drank 193 c. c. of water, and sat down. At 10 h 30 m 

 a. m., he passed 413 grams of urine. At the beginning of the second period, 

 ll h 45 m a. m., he arose from his chair and went through the usual operations 

 in taking his temperature. At ll h 55 m a. m., he again went to the food aperture 

 to get his lunch and a bottle of water, the lunch consisting of 126 grams of 

 nuts, 442 grams of milk, 174 grams of oranges, and 149 grams of sandwich. 

 At the beginning of the third period, l h 45 m p. m., he opened the food aperture 

 twice in taking his temperature, then sat down again. At 2 h 20 m p. m. he went 

 to the rear of the calorimeter, then returned and sat down. The subject usually 

 assisted in the routine of the experiments carried on in the laboratory, and 

 therefore was familiar with the apparatus, although this was his first experience 

 inside the respiration chamber. 



The subject took his own pulse-rate, and the records were as follows: 

 8 h 30 m a. m., 77 ; 9 h 15 m a. m., 75 ; 9 h 45 m a. m., 64 ; 10 h 45 m a. m., 63 ; ll h 30 m 

 a. m., 65 ; 12 h 10 ra p. m., 68 ; 1 p. m., 75 ; 2 p. m., 75 ; 2 h 45 ra p. m., 64. The 

 body-temperatures were sublingual and as follows: 9 h 44 m a.m., 98.5 F. ; 

 ll h 44 m a.m., 98.4 F.; l h 44 m p.m., 98.8 F. ; 3 h 44 m p.m., 98.6 F. The 

 results of the metabolism are given in table 44.
