chair, reading most of the time. During the third period he drank 132 c. c. 

 of water. No food was eaten during the experiment. The subject passed 

 118 grams of urine at l h 15 m p.m., the end of the second period. He was 

 familiar with the apparatus, as he had served as a subject before. 



The pulse, respiration, and body-temperature were taken as in experiment 

 No. 118, the records of the pulse and respiration being given in table 36. 

 The records of the body-temperature were as follows: 9 h II 



36.90 C. 



ll h 15 m a.m., 36.73 C. ; l h 15 m p.m., 36.73 C. 



3 h 15 1 



p.m., 36.67 C; 



5 h 15 m p. m 



36.61 C. The measurements of the metabolism were made in 

 four 2-hour periods and are given in table 11. 



METABOLISM EXPERIMENT No. 151. 



Subject, H. R. D., March 24, 1906. (Same subject as in 

 experiment No. 150.) 



The subject entered the respiration chamber at 7 h 30 m a. m., having eaten 

 no food since the noon meal of the day before. He was weighed at 7 h 10 m a. m. 

 and the first period began at 8 h 10 m a. m. The subject after the beginning 

 of the experiment repeated exactly the operations of the subjects of experiments 

 Nos. 112 and 118 (see p. 61), in that every 5 minutes he went to the food 

 aperture, opened it, closed it, etc., and then returned to his chair. The experi- 

 ment ended at l h 10 m p. m. The subject drank 227 c. c. of water at 3 h 20 m 

 p. m. and passed 181 grams of urine at l h 52 m p. m., after the experiment 

 ended. Most of the time between the operations of going to the food aperture 

 the subject read, and he did not miss going to the food aperture at any time. 

 The average time taken to complete the series of movements was 26.25 seconds. 

 The subject said that while he found it difficult to be exact as to the time of 

 the operation, he did not find the movements tiresome. He said he was not 

 at all drowsy, but felt hungry and somewhat thirsty.
