Metabolism Experiment No. 75. 



Immediately following the 5-day fast, experiment No. 73, the subject had 

 remained in the respiration chamber for 3 days with food. From the morning 

 of February 5, until the evening of March 3, he had been engaged in light 

 occupation, assisting about the laboratory. During this preliminary period 

 his diet had consisted in large part of vegetable materials, milk, and eggs. 



On the evening of March 3, 1905, he entered the respiration chamber and 

 went to bed at 11 p. m. At 1 a. m., March 4, the preliminary analyses of the 

 respiratory products were begun. The experiment proper commenced at 7 

 a. m., March 4, and continued 7 days, during which time no food was eaten. 

 The general routine was similar to that followed in previous experiments with 

 this subject. 



This experiment was the most successful of the series conducted with S. A. B. 

 Though he made a large number of notes concerning various symptoms of 

 illness, nevertheless his verdict at the end of each day (except the sixth), 

 was that he had " passed a comfortable day." 



Notes from diary, pulse records, and records of body movements. The notes 

 from the diary of the subject which embrace practically all his observations 

 concerning his physical and mental condition, are shown below, together with 

 the pulse records and the record of body movements.
