    sweetened with 45 g-raiiis of cane !su<;-:ir, the whole mixture forming !X)U oram.s. which was administered as in experiment No. 18. Experiment No. 20 began at 7 a. m. Februar}' 10, and continued 2 days, during which the diet consisted of the basal ration, supplemented by 113.8 grams of brandy, with 50.1 per cent, or 72.5 grams, of absolute alcohol. The brandy was mixed with 711.2 grams of water, sweetened with 15 grams of cane sugar. The whole mixture amounted to 900 grams, which was admin- istered in 6 portions as in the previous experiments. Experiment No. 21 began at 7 a. m. February 12, and continued 3 days. The diet in this experiment consisted of the basal ration alone, without alcohol. The results of this experiment are here given in comparison with 3 alcohol experiments because it was a part of the same series and followed the alcohol experiments without intermission and without the subject leaving the respiration chamber. The results are hardh' comparable with those of the alcohol experi- ments, however, since by the omission of the alcohol from the diet the amount of energy per day was reduced nearly one-fifth, while the amounts of protein, fats, and carbohydrates remained the same. The following table summarizes the results of these 4 experiments. Detailed data of experi- ments Nos. 18-20 may be found on pages 317 to 330 in the Appendix. Those of No. 21 may be found in Bulletin 109 of the Office of Experiment Stations. Table 10.—Suiiimari/ of results of metabolism experiments Nos. 18, 19, and SO. [Quantities per day.] Protein. Fat.
