GROUP I. EXPERIMENTS NOS. 21 AND 18-20. REST EXPERIMENTS WITH ORDINARY AND WITH 



ALCOHOL DIET. 



The series of experiments comprising this group was carried out in February, 1899. The 

 purpose of the experiments with alcohol diet in this series was the same as that of experiments 

 15-17. namely, to determine whether there is any difference in the effect of alcohol when taken 

 in different forms. Experiments Nos. 18 20 were somewhat similar in plan to Nos. 15-17, but 

 were made with a different subject, A. W. S. The subject remained in the calorimeter '.» days 

 without intermission. During the first 6 days of this period the 3 alcohol experiments. Nos. 

 18-20, were made, each of 2 days' duration, as in experiments 15-17. These were followed by 

 one experiment. No. 21. of 3 days, in which the diet contained no alcohol. 



A.S in the preceding series, the diet in experiment- 18-21 consisted of a basal ration which 

 was the same in all the experiments, and a supplemental ration which was different in each. 

 This basal ration furnished '."7 grams of protein and 2,261 calories of energy per day. In experi- 

 ments Nos. 18-20 the basal ration was supplemented by commercial alcohol, whisky, and brandy, 

 respectively, the quantity of each used being sufficient to furnish 72.5 grams of absolute alcohol 

 per day, with a heat of combustion of 512 calories. The total diet in the alcohol experiments 

 furnished 97 grams of protein and 2,776 calories of energy per day. In experiment No. 21 the 

 alcohol was omitted, and the diet consisted of the basal ration alone. 



The preliminary digestion experiment began with breakfast February 2, and continued 1 days. 

 During this period the diet was the same as in experiment No. 18. and consisted of the basal 

 ration and the alcohol in the form of commercial spirits, which was administered in coffee infusion, 

 sweetened with sugar. 



The subject entered the respiration chamber on the evening of February 5. and experiment 

 No. IS began at 7 a. m. February 6, and continued 2 days. In this experiment the diet consisted 

 of the basal ration, supplemented by 7'.».s grams of commercial alcohol, witli 90.9 per cent, or 

 72. :< grams, of absolute alcohol. The commercial spirits was mixed with 7 7 5.2 grams of coffee 

 infusion, sweetened with 15 grams of cane sugar. The whole mixture made 9( hi grams, which 

 ua- divided into 6 portions, the larger of which were taken with meals, and the smaller between 

 meals and just before retiring. 



Experiment No. 19 began at 7 a. m. February 8. and continued 2 days. The diet in this 

 experiment consisted of the basal ration, supplemented by 158.3 grams of whisky, with 15.8 

 per cent, or 72.5 grams, of absolute alcohol. The whisky was mixed with 696.7 grams of water,
