EXPERIMENTS NOS. 26-28 — REST. NO. 27 WITH ALCOHOL DIET. 



Subject. — J. F. S., a eheLiist. 29 years of aye. His weight with underclothing was about 64 

 kilograms (141 pounds). 



Occupation during experiment. — Reading, writing, and miscellaneous observations within 

 the apparatus, with as little muscular activity as was practicable. 



Duration. — This experiment was the second of a series of 3 experiments, each continuing 3 

 days. The series was preceded by a preliminary period of 4 days, beginning with breakfast 

 Feliruary 10, 1900. The subject entered the calorimeter on the evening of February' 13. The 

 first experiment of the series, No. 26, began at 7 a. m. February 14; the second, No. 27. at 7 a. m. 

 February 17, and the third, No. 28, at 7 a. m. February 20. The whole period of the metabolism 

 experiments was thus 9 days. 



Diet. — A basal ration of ordinary food furnished 99 grams of protein and 1,982 calories of 

 energy per day. To this was added in experiment No. 26, 63.5 grams of butter, furnishing 

 1 gram of protein and 508 calories of energy; in experiment No. 27, 79.5 grams of 90.6 per cent 

 alcohol, furnishing 509 calories of energy, and in No. 2S, 128 grams of cane sugar, furnishing 

 507 calories of energy per day. The protein and energy was thus practically the same in each of 

 the 3 experiments of this series. In experiment No. 27 the 79.5 grams of commercial alcohol, 

 containing 72 grams absolute alcohol, was added to 792.5 grams of water sweetened with 15 grams 

 of sugar. The alcohol was taken in 6 doses, as indicated in the following schedule. The kinds 

 and quantities of food in the basal ration, as served for each meal, the character and amount of 

 the supplemental ration in the different experiments, and the. quantity of drink consumed at 

 different periods of the day were as follows:
