50 Metabolism of Healthy Man. 



made a number of movements while doing this. He ate lunch until about 

 ll h 40 m a. m. The lunch consisted of 177 grams of sandwich, 574 grams of 

 oranges, 238 grams of milk, and 115 c. c. of water. After eating his lunch 

 he remained quiet and read till the end of the experiment, except when ob- 

 serving his temperature and pulse. 



The subject was an assistant in the respiration-calorimeter experiments, and 

 although this was his first experience inside the chamber, he made very little 

 comment, except to say that the air was good and that the temperature appeared 

 to be somewhat lower about noon. 



The pulse-rate as taken by the subject was as follows : 9 h 02 m a. m., 80 ; 

 9 h 30 m a.m., 77; 10 h 30 m a.m., 70; ll h 35 m a.m., 68; 12 h 15 m p.m., 64; 

 l h 15 m p. m., 67 ; 2 h 15 m p. m., 69 ; 2 b 50 ra p. m 66. The sublingual body- 

 temperatures were at 9 a.m., 98.0 F. ; 11 a.m., 97.9 F.; 1 p.m., 98.1 F.; 

 3 p.m., 98.0 F. The results of the metabolism in this experiment, as meas- 

 ured in three 2-hour periods, are given in table 44. 



METABOLISM EXPERIMENT No. 127. 



Subject, R. D. M., May 12, 1905. Age, 35 years 9 months; 

 height, 178 cm.; weight without clothing, 70.4 kilos. 



After a breakfast consisting of crackers and milk, the subject entered the 

 calorimeter at 7 h 45 m a. m. and was weighed at 7 h 58 m a. m. He then seated 

 himself in the chair and remained quiet until 8 h 48 m a. m., when the experi- 

 ment began. At the beginning of each period the subject followed the usual 

 routine in taking his temperature. At 8 h 52 m a. m. he commenced working on 

 a manuscript and occupied all his time during the first period in reading this 

 manuscript, except that at 9 h 12 m a. m. he went to the food aperture to get 

 a sheet of paper. During the second period he read until ll h 50 m a. m. At 

 that time he opened the food aperture three times without getting up from 

 his chair and took out his lunch. He was eating between ll h 50 m a. m. and 

 12 h 24 m p. m. During this time he went to the food aperture once to get a 

 knife and then sat down. The lunch consisted of 120 grams of sandwich, 

 320 grams of oranges, 150 grams of bananas, and 466 grams of milk. At 1 

 p. m. the subject replaced the thermometer in the food aperture and then 

 during the rest of the time until the finish of the experiment at 2 h 48 m p. m. 

 he was reading. 



The subject was an editorial assistant in the nutrition investigations and 

 this was his first experience as a subject inside the respiration chamber. He 

 was affected by his sojourn in the chamber, although this effect did not take 

 place until after he had left the laboratory. The details regarding this indis- 

 position have been given by us elsewhere. 1 



The pulse-rate as taken by the subject was as follows : 8 h 30 m a. m., 77 ; 

 9 a. m., 77; 10 a. m., 68; 11 a.m., 63; 12 noon, 63; 1 p.m., 62; 2 p.m., 67;
