The alcohol, or reducing material equivalent to alcohol, was determined in the urine and freezer 

 water of each day of experiment No. 30, and on the 3 days of the preceding and following 

 experiments, Nos. 29 and 31, respectively. The amount of reducing material in the air current 

 on each day of the 9 days of this series of experiments was also determined. Table LXXXV 

 summarizes these determinations. The determinations of the reducing material in the urine on 

 the first day of experiment No. '2'.t was lost, so that we can only estimate the total reducing 

 material on that day. It was. however, probably not far different from the second and third 

 days of this experiment. The average elimination of reducing material per day from all sources 

 in experiments Nos. 29 and 31 amounted to the equivalent of 0.32 gram of alcohol. In the 

 third from the last column of Table LXXXV is given the total outgo of alcohol in experiment 

 No. 30, which amounts to 0.76 gram per day. This value is obtained by subtracting from the 

 1.09 grams of total alcohol and reducing material equivalent to alcohol the 0.33 gram of reducing 

 material determined during the experiments in which alcohol did not form a part of the diet. 

 The total alcohol metabolized in the body was 98.9 per cent of that ingested. 



Table LXXXV. — Alcohol ingested and excreted — Metabolism i xpi rum nt Nos. 29S1. 



* Equals total reducing material excreted less 0.33 gram of reducing; material not alcohol, the average for the days 

 on which no alcohol was consumed. 

 1 Not determined.
