EXPERIMENTS NOS. 26, 28, AND 27. REST EXPERIMENTS WITH ORDINARY DIET AND WITH 



ALCOHOL DIET. 



The series of experiments forming- this group was carried out with J. F. S. in February, 

 L900. The purpose of the experiments was to obtain data concerning the relative power of 

 isodynamic quantities of alcohol, sugar, and butter to replace one another in the diet, when the 

 subject was at rest. During this series the subject remained in the calorimeter 9 days and 10 

 nights, and each experiment continued 3 days and nights. The diet consisted of a basal ration 

 furnishing approximately 100 grams of protein and L,982 calories of energy per day, which was 

 uniform in all 3 experiments, and a supplemental ration which was' differed in the several experi- 

 ments, being butter in No. 26, alcohol in No. 27, and sugar in No. 28, the amount of each used 

 being sufficient to furnish about 500 calories of energy. 



The preliminary digestion experiment began with breakfast on February 10, and continued 

 4 days. During this preliminary period the diet consisted of the basal ration supplemented by 

 (13.5 grams of butter, furnishing 0.1 of a gram of nitrogen and 508 calories of energy: thus making 

 a total of 100 grams of protein and 2,490 calories of energy in the daily diet. 



The subject entered the respiration chamber on the evening of February 13, and experiment 

 NO. 26 began at 7 a. m. February 14, and continued 3 days. During this experiment the diet 

 consisted of the basal ration supplemented by fat in the form of butter, as in the preliminary 

 digestion experiment. 



Experiment No. 27 began at 7 a. m. February 17. and continued 3 days. During this experi- 

 ment the diet consisted of the basal ration supplemented by 79.5 grams of commercial ethyl 

 alcohol with 90.6 per cent or 72 grams of absolute alcohol supplying 509 calories of energy per 

 day. so that during this experiment the daily diet furnished 99 grams of protein and 2,491 

 calories of energy. The alcohol was administered in sweetened water, and the mixture was 

 consumed in i> portions during the day, 3 with meals and 3 between meals. 



Experiment No. 28 began at 7 a. m. February 20, and continued 3 days. The diet during 

 this experiment consisted of the basal ration supplemented by 28 grams of sugar daily in the 

 form of rock candy. The daily ration during this experiment thus furnished '.»;• grams of protein 

 and 2,889 calories of energy. The total amount of rock candy for the day was supplied to the 

 subject with his breakfast, and he ate it from time to time during the day according to his taste.
