STATISTICS OF EXPERIMENTS WITH H. H. A. 

 Respiration Experiment No. 1. 



Date, December 27, 1911. Body-weight without clothing, 63.5 kilos. 



The diet on the day preceding the study was a mixed diet. Breakfast: 

 coffee, with sugar, fried potatoes, and bread. Dinner: barley soup, potatoes, 

 bread, apple pie, coffee, hard candy. Supper: fried potatoes, tea with sugar,

 8 h 50 m a. m., continued for four 15-minute periods with intervals of 8 to 10 

 minutes, and ended at 10 h 18 m a. m. The pulse-rate ranged from 74 to 82. 

 The subject urinated before the experiment at 7 a. m., and after it was over, at 

 10 h 25 m a. m. A sample of the blood was taken at ll h 10 m a. m. The results 

 of the experiment may be found in table 138. 



Respiration Experiment No. 2. 



Date, December 27, 1911. Body-weight without clothing, 63.5 kilos. 



This experiment was made on the afternoon of the day of the preceding 



experiment, being the first with a carbohydrate-free diet. At 12 o'clock noon 



the subject took for his dinner steak and butter, with a cupful of beef tea. The 



experiment, which consisted of two 15-minute periods, began at 4 h 38 m p. m. 



and ended at 5 h 19 m p. m. The pulse-rate ranged from 94 to 104. After the 



experiment the subject ate for his supper, at 6 p.m., scrambled eggs, butter, 



and tea without milk or sugar. The results of the experiment are given in 



table 138.

The subject came to the laboratory without breakfast, lay down upon the 

 couch at 7 h 45 m a. m., and a blood sample was taken about 8 h 12 m a. m. The 

 experiment began at 9 a. m., continued for three 16-minute periods, and ended 

 at 10 h 03 m a. m. The pulse-rate ranged from 78 to 88. The subject urinated 

 at 10 h 35 m a. m. 



The diet for this day consisted of eggs, butter, and coffee at 12 o'clock; 

 cheese, fried eggs, bacon, and beef tea at 3 p. m., and lean pork chops and tea 

 at 7 h 30 m p. m. The results of the experiment may be found in table 138. 



Respiration Experiment No. 4. 



Date, December 29, 1911. Body-weight without clothing, 61.3 kilos. 



Previous to the experiment, the subject said he felt very well, fully equal 

 to taking a long walk. He came to the laboratory without breakfast. The 

 experiment began at 8 h 12 m a. m. and continued for five periods of 15 to 16 

 minutes each. The subject urinated at 7 and ll h 25 m a. m. On this day he 

 ate, at 12 h 35 m p. m., eggs and fried ham, with weak coffee; at 3 p. m., boiled 

 scrod with butter, and beef tea ; and at 7 p.m., fried lamb chops and tea. The 

 results of the experiment are given in table 138.

Date, December 30, 1911. Body-weight without clothing, 61 kilos. 



No breakfast was taken by the subject on the day of the experiment. The 

 respiration experiment began at 10 h 46 m a. m. and continued for one 8-minute 

 and two 15-minute periods, ending at 12 h 12 m p. m. The pulse-rate during the 

 experiment ranged from 67 to 78. The subject urinated at 7 a. m. and 12 h 30 m 

 p. m. He took food during the day as follows: l h 10 m p. m., scrambled eggs,
