Metabolism Experiment No. 68. 



57 



The following notes from the diary of the subject are of especial interest as an 

 index of his physical state : 



Notes from diary. 



April 27, 1904. Took a lampblack capsule this morning and drank a little water. 

 The day passed quite quickly because of interesting reading matter. Felt a little 

 craving for food in the evening and some weakness. Retired and slept well, waking 

 a little before 7 a. m. 



April 28, 1904. Felt a definite craving for food about breakfast time, but it soon 

 passed away. Felt weak and lifeless; belched considerable wind. About bedtime 

 I felt unusually weak. This was particularly noticeable because I had not been 

 moving around for some time. After lying down I didn't feel very hungry and 

 soon went to sleep. Was wakeful and restless during the latter part of the night. 



Routine. Since it interferes materially with fasting subjects to insist upon 

 a prescribed routine, the subject of this experiment was only cautioned to 

 minimize so far as possible the muscular movements. His experience of the 11 

 preceding days aided materially in securing uniform experimental conditions 

 during the fasting period. The experimental day began as usual at 7 o'clock 

 in the morning and, since the last meal was taken at 6 o'clock the night before, 

 there had been a fast of 13 hours before the experiment proper began. 



Body movements. The usual movements incidental to drinking water, taking 

 pulse, caring for excreta, opening and closing the food aperture, etc., were 

 unavoidable. Although the subject attempted to secure uniform bodily activity 

 on the two days of the experiment, an inspection of the record of body move- 

 ments will show that this was extremely difficult. The major body movements 

 obtained by the physical observer and reported in the diary of the subject are 

 given herewith. 



Movements of subject. Duration, tico days, from Apr. 27, 7 a. m., to Apr. 29, 



7 a. m., 1904. 



1 Places the bicycle ergometer in the position in which it is usually ridden.
