Elimination of unoxidized alcohol. — The urine, freezer water, and air current were tested 

 for alcohol or products of incomplete oxidation of alcohol by the method referred to on page 258 

 above. The results obtained in this experiment are shown in Table XIV. It will be observed 

 that 98 per cent of the alcohol taken with the food was apparently oxidized in the body. Inas- 

 much, however, as it has since been found a that even when alcohol forms no part of the diet 

 there is a considerable amount of organic material in the urine, drip water, and ventilating air 

 current which is capable of reducing the chromic acid employed, it is probable that the actual 

 elimination of unoxidized or incompletely oxidized alcohol is considerably smaller than is indicated 

 by the figures in the table.
