The l>as:il ration furnished L23 grams of protein and 2,535 calories of energy per day. To this 

 ration was added, in experiment No. 22, T'.'.i' grams of 90.9 per cenl commercial alcohol. This 

 contained 72 grams of absolute alcohol and furnished 509 calories of energy. In experiment No. 

 23 the subject had 30 grams of horse radish, furnishing- 11 calories of energy per day, and in 

 experiment No. 24. 3i> grams of horse-radish, furnishing 11 calories of energy, and 130 grams of 

 cane sugar, furnishing 515 calories of energy. Leaving the small quantities of horse-radish out 

 of account, the diet of experiment 22 supplied the basal ration plus alcohol, No. 23 the basal 

 ration alone, and No. 24 the basal ration plus an amount of sugar isodynamic with the alcohol of 

 No. 22. In experiment No. 22 the alcohol was taken in the usual doses, 3 with and 3 between 

 meals and upon retiring. It was prepared by adding 79.2 grams of 90.9 per cent alcohol to 780.8 

 grams of eott'ee infusion sweetened with 40 grams of sugar. This mixture thus contained 72 

 grams of absolute alcohol. 40 grams of sugar, and 788 grams of water. The kinds and quantities 

 of food served at each meal and the quantities of drink at different periods were as follows:
