Dressing and Undressing Experiments. 83 



doing plain copying. The undressing period was from 12 h 15 m p. m. to l h 15 m 

 p. m., and the subject followed the usual routine for the undressing period. 

 He was without clothing 2 m 36 s . 



The pulse-rate as taken by the subject was as follows : 8 h 25 m a. m., 8G ; 

 10 h 35 ra a.m., 77; 10 h 37 m a.m., 75; 10 h 41 m a.m., 82; 12 noon, 65; 12 h 02 ra 

 p.m., 68; 12 h 14 m p.m., 70. The sublingual body-temperature as taken in 

 this experiment was as follows: 9 h 15 ra a. m., 98.4 F. ; 12 h 15 m p. m., 97.8 F. : 

 l h 15 m p. m., 97.9 F. The results of the metabolism are recorded in table 44. 



METABOLISM EXPERIMENT No. 165. 



Subject, H. D. A., February 28, 1905. Age, 21 years 6 montbs; 

 height, 161 cm.; weight without clothing, 67.2 kilos. 



The subject entered the chamber at 1 o'clock, after a dinner consisting of 

 meat pie, potato, stewed tomatoes, and an orange. He was weighed at l h '?4 m 

 p. m. and the rest period began at 2 h 03 m p. m., and continued until 5 h 03 m 

 p. m. During the first 2 hours the subject was writing. At 2 h 06 ra p. m. he 

 went to the food aperture. The undressing period was from 5 h 03 m p. m. to 

 6 h 03 m p. m. The routine followed was the same as in the preceding experi- 

 ments ; the subject was undressed 6 m 46 s . 



The pulse-rate was recorded by the subject as usual and was as follows: 

 2 p. m., 82 ; 2 h 30 m p. m., 73 ; 3 p. m., 71 ; 3 h 32 m p. m., 69 ; 4 p. m., 65 ; 

 4 h 30 m p.m., 67; 4 h 58 m p.m., 66; 5 h 28 m p.m., 63; 6 p.m., 67. The sub- 

 lingual body-temperature was as follows : 2 h 03 m p. m., 98.5 F. ; 5 h 03 m p. m., 

 98.0 F.; 6 h 03 m p. m., 98.1 F. The results of the metabolism for the experi- 

 ment are recorded in table 44. 



METABOLISM EXPERIMENT No. 166. 



Subject, H. L. K., March 1, 1905. Age, 23 years 4 months; 

 height, 166 cm.; weight without clothing, 57.1 kilos. 



The subject, who was also used in experiment No. 130, entered the respira- 

 tion chamber after a breakfast consisting of 1 banana, 4 tablespoonfuls of 

 prepared cereal, 15 teaspoonfuls of light cream, a cup of coffee with 10 tea- 

 spoonfuls of heavy cream, and 2 teaspoonfuls of sugar, 1 egg, 1 biscuit, and 

 1 doughnut. He was weighed at 8 a. m. and the rest period began at 8 h 54 

 a. m., and continued until ll h 54 m a. m. A part of this time he was occupied 

 in copying from reports and a magazine. At 8 h 58 m a. m. he went to the food 

 aperture. The undressing period was from ll h 54 m a. m. to 12 h 54 m p. m., and 

 during this time he went through the usual routine of opening the food 

 aperture twice, lowering the shields, hanging the chair, being weighed, and 

 then taking down the chair, undressing, hanging the chair again, being weighed, 

 and then dressing, opening the food aperture, and raising the shields. The 

 subject was undressed 2 m 9 s .
