sweetened with 45 grams of cane sugar, the whole mixture forming- 900 grams, which was 

 administered as in experiment No. 18. 



Experiment No. 20 began at 7 a. m. February 10, and continued 2 days, during which the 

 diet consisted of the basal ration, supplemented by 143.8 grams of brandy, with 50.4 percent, or 

 72. 5 grams, of absolute alcohol. The brandy was mixed with 711.2 grams of water, sweetened 

 with 45 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 J 2, 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 hardly 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.
