■ Including 50 grains used in coffee infusion and alcohol. 

 b Added to coffee infusion and taken as indicated below. 

 Made by adding 80 grams of 90.5 per cent commercial alcohol and 50 grams sugar to 800 grams coffee infusion. 

 The mixture then contained 807.5 grams water, 72.4 grams absolute alcohol and 50 grams sugar. 



Daily routine. — In order to make the conditions of the experiment on the different days as 

 nearly uniform as practicable a daily programme was drawn up and one copy was given to the 

 subject within the respiration chamber while others were posted outside for the use of those 

 carrying on the details of the experiment. The routine in experime.it No. 12 was as follows: 



Daily program — Metabolism experiment No. /.'. 



The subject weighed himself, with and without clothing, at about 7 a. m. and 7 p. m. each 

 day of the experiment. He observed his pulse rate, after intervals of rest, and took his body 

 temperature from time to time by means of a registered clinical thermometer. The body 

 temperatures were measured sub lingua. We do not think that great reliance can be placed 

 upon observations for either pulse rate or temperature when made by the subject upon himself 

 under such conditions. 



A hygrometer inside the chamber was observed two or three times each day in order to give 

 data concerning the amount of water vapor within the calorimeter, but the figures are not used 

 in the final computations of results.
