periods from l h 10 m a. m. to 7 h 10 m a. m. The rectal temperatures are here 

 reported for each 2 hours after the thermometer was readjusted at 7 h 16 m a. m. 

 The body-temperature records were as follows: 7 h 20 m a. m., 36.44 C. ; 9 h 10 m 

 a. m., 36.01 C. ; ll h 10 m a. m., 36.57 C. ; l h 10 m p. m., 36.48 C. The metab- 

 olism was measured in 2-hour periods and the results for the portion of the 

 experiment here reported are given in table 44. 



METABOLISM EXPERIMENT No. 154. 



Subject, J. H. K., April 17, 1906. Age, 54 years 2 months; 

 height, 164 cm.; weight without clothing, 56.1 kilos. 



The subject (a physician) entered the respiration chamber at 12 h 30 m p. m. 

 and was weighed at 12 h 45 m p. m. The experiment as reported consists of three 

 parts, the first part from 2 p. m. to 6 p. m.. when the subject was on his feet 

 all the time and either walking or standing or lifting himself as when walking; 

 the second part, from 7 h 15 p. m. to 9 h 15 m p. m., when he was lying asleep 

 or quietly awake; and the third part from 9 h 15 m p. m. to ll h 15 m p. m.. when 

 he was lying quietly awake. The measurements were in 2-hour periods. Dur- 

 ing most of the time from 2 p. m. to 6 p. m. the subject was walking a pace 

 or two forward or backward, as the narrow confines of the chamber permitted. 

 Occasionally he stood, and at one time he stood and went through calisthenic 

 exercises for a few minutes. At 3 h 06 m p. m. the subject took off his coat and 

 vest and ate 136 grams of orange, while standing still. At 5 h 42 m p. m. he put 

 on his coat. At 6 p. m. an intermediate period began, during which the subject 

 adjusted the bed and then sat down. A lunch consisting of 348 grams of 

 oranges was eaten at 6 h 22 m p. m. The subject then placed the uneaten food 

 in the food aperture, lay down upon the bed, picked up the blanket, and 

 spread it over his feet, and was quietly reading at 6 h 48 m p. m. The second 

 part of the experiment began at 7 h 15 m p. m., and the subject was probably 

 asleep at this time. He remained very quiet until 8 h 16 m p. m., when he awoke. 

 At 8 h 22 m p. m. he picked up his glasses from the floor and then removed 

 the blanket from his feet. From that time on until the end of the experiment 

 the subject was lying down and reading most of the time. At about ll h 06 m 

 p. m. the subject rose, and after picking up his glasses he lay down again. 

 The experiment was concluded at ll h 15 m p.m. 



The subject estimated that he took about 1 step a second while walking 

 and raised his body about 1.5 miles, and that the work done during the first 

 portion of the experiment was not as much as he would ordinarily do at his 

 home while walking. He reported that he slept about 1 hour during the 

 second portion of the experiment, as noted on his watch. He was not soundly 

 asleep all of the time, but was very quiet. This was his first experience in 

 the chamber. 



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

 and were as shown in table 40. During the first part of the experiment, the
