Metabolism Experiment No. 69. 



This experiment, which continued for 4 days, was made with the same subject 

 as experiment No. 68, but 7 months later. The subject entered the respiration 

 chamber on the evening of December 15, 1901, the experiment proper beginning 

 at 7 a. m., December 16. Preliminary practice in adjustment of furniture and 

 apparatus inside the calorimeter chamber was not necessary, as this subject 

 had previously participated in a large number of experiments. He was also 

 thoroughly accustomed to the environment. The usual clothing was worn and 

 the general plan of the whole experiment was similar to that of experiment 

 No. 68. 



It has already been suggested that A. L. L., the subject of this experiment, 

 was of phlegmatic temperament. The following notes from his diary contain 

 practically everything he wrote, and so brief are they that their value for 

 deduction as to the physical or psychical condition of the subject a** practically 

 worthless. They simply serve to indicate that the stay in the calorimeter was 

 not distasteful to the subject and that he felt little ill effect from his fast.

Notes from diary. 



Dec. 16, 1904: 

 Lay down this morning at 9 and re- 

 mained on the bed until 1 p. m. 

 Slept the greater part of the time, 

 but with disturbed dreams during 

 the last of it. 

 Dec. 17, 1904: 

 While adjusting the heat absorbers this 



morning, I felt a little faint. Have 

 had no desire for water, but have 

 drunk as ordered. 20 

 Dec. 18, 1904: 

 Nothing worthy of note regarding this 

 day. 



Dec. 19, 1904: 

 Day passed quite as the rest. 



Pulse. In this experiment the subject counted his pulse twice each day. 

 The count was made for two minutes and the average number of beats per 

 minute is recorded below. 



Routine. Aside from conforming to the general experimental period so far 

 as hours of sleep, rising, collection of urine, etc., was concerned, the subject 

 was allowed to do as he pleased except that he was cautioned to secure, in so 

 far as possible, uniform muscular activity on the several days of the experiment. 



20 Owing to the unusually high specific gravity of the urine of this subject in 

 previous experiments he was requested to drink liberal amounts of water.
