The statistics of the diary kept by the subject arc summarized in Tabic NNNIII. 

 Table XXXIII. — Summary of diary — Metabolism experiments Nos. 18-20. 



Detailed statistic? of vncorru <ni<i outgo. — The usual statistics of income and outgo of matter 

 and energy are shown in Tables XXXIV to XLVI, which follow. The diet was the same during 

 the series of experiments Nos. 18-20, except in the form of alcohol taken. It supplied 97 grams 

 of protein and 2,776 calories of energy per day. In experiment No. 21, which immediately 

 followed, the diet was the same, with the exception that no alcohol was administered, so that the 

 total energy of the food was only 2,261 calories. 



No separation of the feces was obtained between the beginning of the preliminary period 

 and the end of experiment No. 21, in which the subject had what may be called the basal ration 

 without the alcohol. It was necessary, therefore, to assume a uniform amount of feces from the 

 food from day to clay. While this may introduce a slight error in the results of the 3 experi- 

 ments with alcohol, Nos. 18-20, such error can hardly be large enough to affect seriously the 

 computed results of the experiments.
