METABOLISM EXPERIMENT No. 141. 



Subject, A. H. M., February 14, 1906. (Same subject as in 

 experiment No. 137.) 



The subject entered the respiration chamber at about 7 h 30 m a, m. without 

 breakfast and was weighed at 7 h 36 a. m. The experiment began at 9 a. m. 

 and continued for 8 hours. No food was eaten, as this experiment was planned 

 for the study of the metabolism during the first hours of fast and the subject 

 had not eaten since supper the night before, when he ate a dish of beans, 2 

 slices of graham bread with a small quantity of peanut butter, a dish of oat- 

 meal, and a glass of milk. The subject passed 239 grams of urine at about 

 12 noon, and 162 grams at 5 h 25 m p. m. after leaving the chamber. He did 

 not drink any water. A minimum of activity was sought and consequently 

 the subject was fairly quiet throughout the experiment. This experiment is 

 introduced here for comparison with a following experiment in which the 

 conditions were the same except that a special series of muscular movements 

 was introduced. 



The pulse- and respiration-rates were taken by means of the pneumograph. 

 The results are given in table 27. The body-temperature was taken in the 

 rectum by means of the electrical-resistance thermometer. The records for 

 each 2 hours were as follows: 9 a. m., 36.42 C. ; 11 a. m., 36.50 C. ; 1 p. m., 

 36.43 C; 3 p.m., 36.22 C; 5 p.m., 36.17 C. The measurements of the 

 metabolism during the four 2-hour periods are given in table 44. 



METABOLISM EXPERIMENT No. 142. 



Subject, A. H. M., March 26, 1906. (Same subject as in 

 experiment No. 137.) 



This experiment, as well as experiments Nos. 148 and 151, was designed to 

 study the increase in metabolism required by the muscular activity incidental to 

 rising from the chair, going to the food aperture, opening it and inserting an 

 article (a urine jar), closing the food aperture, opening it again, removing the 

 urine jar, closing the food aperture, and then resuming the position in the chair, 

 a series of movements of hourly occurrence in the routine of most experiments 

 with the respiration calorimeter. The subject in each of these experiments was
