"If this question is answered affirmatively, then alcohol is a food. If negatively then alcohol is not a food. Let us reason together. All body oxidations may be classified in two groups: (1.) Active oxidations which take place in the active tissues—muscles, nervous system, or glands and take place incident to action. It is under the perfect control of the nervous system and is proportional to normal activity. (2.) Protective oxidations which take place in the liver. This class of oxidation processes is wholly independent of the usual tissue activity and is proportional to the ingestion of toxic substances and quite independent of muscle action, brain action, or gland action, other than liver action.
"If the oxidation of alcohol in the liver belongs to class 1, the following consequences should be found: (1.) The ingestion of alcohol would lead to an increase in muscular power and in the working capacity of the brain or glands. (2.) The ingestion of alcohol would serve to maintain body temperature in the healthy individual subjected to low external temperature. (3.) The accession of muscle, brain, or gland activity would be proportional to the amount of alcohol ingested, but laboratory observations and general experience show that none of these things are true; i. e., the ingestion of alcohol decreases muscle, brain, and gland work, and depresses body temperature when external temperature is low.
"In the nature of the case there can be no proportional relation. The oxidation of alcohol does not therefore belong to class 1. If the oxidation of alcohol in the liver belongs to class 2, the following consequences would be found: (1.) The ingestion of alcohol would be followed by its early oxidation in the organs in question. (2.) If the oxidation capacity of the liver is limited this capacity may be overloaded by exceeding the physiological limit of alcohol. (3.) If the oxidation capacity of the liver is taxed nearly to its limit in the oxidation of uric acid, xanthins, and other toxic substances, the introduction of alcohol may seriously interfere with this protective oxidation by overtaxing the capacity. (4.) If the oxidation capacity is overtaxed, an excess of uric acid, xan-
