36 Metabolism of Healthy Man. 



The pulse-rate was taken by the subject himself and recorded in the diary. 

 No respirations were recorded. The records of the pulse-rate as reported by the 

 subject are as follows: 



May 5 9 h 40 m p. m 61 May 6 3 h 16 m p. m 51 



May 6 7 19 a. m 59 3 56 65 



9 45 51 



10 51 56 



12 10 p. m 61 



1 10 53 



4 45 65 



6 49 71 



7 52 68 



The body-temperature was taken from 7 h 30 a. m. until 9 p. m., May 6, by 

 means of the electrical rectal thermometer, and was as follows:

No food was taken during the whole experiment. 



Metabolism and heat production. The results of the gaseous exchange, the 

 heat elimination, and, in so far as the data permit, the heat production are 

 given in table 44. As the results obtained in the experiment reported are 

 compared with results obtained in experiments of a similar nature, it is neces- 

 sary here only to call attention to the fact that the metabolism as indicated by 

 the gaseous exchange and heat production was fairly regular for particular 

 conditions throughout the experiment. The noticeable inequalities appeared 

 only during those periods when the subject was more or less asleep, or when 

 he was more or less muscularly active. Of special significance is the noticeable 

 increase in the carbon-dioxide elimination and oxygen consumption during 

 the evening of May 6 when the subject was disturbed by nausea. The indica- 

 tions are that the last few periods of this experiment can not be considered 

 as normal, and hence in the averages the results for these periods will not 

 be included. 



METABOLISM EXPERIMENT No. 106. 



Subject, B. F. D., May 31, 1905. (Same subject as in 

 experiment No. 103.) 



The subject entered the chamber between 1 and 2 p. m. for a short experiment 

 of only 2 h 30 m . This subject had been sick in a previous experiment and a 

 series of experiments was begun to ascertain if he could remain in the calorim- 

 eter over night without becoming ill. At that time the indisposition men- 

 tioned was attributed to no especial cause, as evidence pointing towards mer- 

 curial poisoning had not then accumulated. No body-temperatures were taken, 

 nor were pulse-rates recorded during this experiment, as it was practically pre- 

 liminary to the series. 



The subject experienced no difficulty during this period, so he was removed 

 and a longer experiment planned for the near future. The results of the 

 metabolism for this one period are recorded in table 44.
