stood in one position, not moving about and without leaning. The experiment 

 ended at 6 h 45 m p. m. and at 7 h 05 m p. m. 28 grams of urine were passed. 

 The subject said that he felt quite well all the time, that the large amounts 

 of bananas and sugar caused him no discomfort, but that the standing still 

 upright troubled him considerably. The subject drank no water during the 

 entire experiment. 



This experiment is one of a series made for the purpose of studying the prob- 

 lem of the cost of digestion. The period of standing was incidental, and the 

 main portion of the experiment will therefore be presented in a later publication 

 treating the subject of digestion as studied in a large number of experiments. 

 The results for the last 4 hours are given in table 44 for a comparison of the 

 metabolism under two different conditions of muscular activity. 



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

 and the records for the two periods between 4 b 45 m p. m. and 6 h 45 m p. m. are 

 given in table 38. The rectal body-temperature was taken with the electrical- 

 resistance thermometer. The temperatures for each 2 hours of the periods 

 here reported were at 2 h 45 m p. m., 36.86 C; 4 h 45 m p.m., 36.59 C; 6 h 45 m 

 p. m., 36.84 C. The metabolism for the last 2 hours of sitting and the 2 hours 

 of standing are given in table 44.

Subject, H. R. D., May 18, 1906. (Same subject as in 

 experiment No. 150.) 



The periods here reported were part of an experiment which began at 9 h 10 m 

 a. m., May 17, and was made for the study of the problem of the ingestion of 

 food. The subject entered the chamber at 7 h 30 m a.m., May 17, was weighed, 

 and then ate 153 grams of gluten bread, and 499 grams of skim milk between 

 8 b 29 m a. m. and 9 h 08 m a. m. He remained seated in the chair during the
