METABOLISM EXPERIMENT No. 145. 



Subject, H. A., November 14-15, 1905. Age, 18 years 10 months; 

 height, 170 cm.; weight without clothing, 64.1 kilos. 



The subject, a student, entered the respiration chamber in the early after- 

 noon of November 14 ; the experiment began at 3 p. m. and continued for ten 

 2-hour periods. Immediately after the beginning of the first period, the 

 chair, subject, bed-clothing, and other articles were weighed as described in 

 previous experiments. After the weighing was finished the subject removed 

 the chair from the suspension rod, put up the table, seated himself in the chair, 

 and remained quiet until 4 h 54 m p. m., when he got up to urinate. At 5 h 58 m 

 p. m. he took the material for his supper from the food aperture and ate 60 

 grams of prepared cereal and 245 grams of cream. He finished eating at 

 6 h 14 m p. m., at which time he placed the remainder of the food in the food 

 aperture and then sat down. At 6 h 38 m p. m. he rose and examined the chamber 

 connections of the rectal thermometer and then sat down. The evening, except 

 that he stood up and sat down at 8 h 24 m p. m., was spent in reading until 

 10 h 10 m p. m., at which time he took down the table, stood up, and then ar- 

 ranged the bed. At 10 h 16 m p. m. he lay down and remained quiet until after 

 lip. m., when he hung up the curtain and retired. 



At 7 a. m., November 15, the subject was awakened, rose and passed urine, 

 and then put up the bed. He had had trouble in adjusting the bed and so 

 went to the food aperture to get some wire. The weighings of the chair, sub- 

 ject, and bedding were then made as usual. The subject then took down the 

 chair, dressed, went to the food aperture several times, and finally put up 

 the table for reading and sat down. He remained quiet until 8 h 14 m a. m., at 

 which time he got up and went to the food aperture. After returning from 

 the food aperture he took down the table, arranged the bed, and lay down 

 and remained quiet until the end of the experiment, which was at 11 a. m. 



This subject had been in the chamber in a previous experiment, the results 

 of which are reported elsewhere. 1 



The pulse and respiration were taken by means of the pneumograph and 

 the body-temperature by means of the electrical-resistance thermometer, and 

 the results are given in table 31. Unfortunately, the pneumograph became 

 displaced in the early morning of November 15, and records could not be 

 secured after 4 h 27 m a. m. The body-temperatures in the rectum every 2 hours 

 were as follows : 



November 143 p.m., 37.23 C; 5 p.m., 37.15 C; 7 p.m., 37.37 C. 

 9 p.m., 37.21 C; 11 p.m., 37.02 C; November 151 a.m., 37.23 C. 

 3 a.m., 37.39 C; 5 a.m., 37.41 C; 7 a.m., 37.26 C; 9 a.m., 37.02 C. 

 11 a. m., 37.18 C. For some unexplainable reason the body-temperatures 

 during the night were higher than would normally be expected with this
