In other words, brandy played the part of a _foe_ in his system, not that of a friend; it produced effects which were morbid, not healthy. Nor did it make any material difference whether St. Martin drank brandy, whiskey, wine, cider, or beer, except so far as one was stronger than the other. "Simple water," says Dr. Beaumont, "is perhaps the only fluid that is called for by the wants of the economy. The artificial drinks are probably _all_ more or less injurious; some more so than others, but none can claim exemption from the general charge. Even tea and coffee, the common beverages of all classes of people, have a tendency to debilitate the digestive organs.... The whole class of alcoholic liquors may be considered as narcotics, producing very little difference in their ultimate effects upon the system." He ascertained too (not guessed, or inferred, but _ascertained_, watch in hand) that such things as mustard, horse-radish, and pepper retard digestion. At the close of his invaluable work Dr. Beaumont appends a long list of "Inferences," among which are the following: "That solid food of a certain texture is easier of digestion than fluid; that stimulating condiments are injurious to the healthy system; that the use of ardent spirits _always_ produces disease of the stomach if persisted in; that water, ardent spirits, and most other fluids, are not affected by the gastric juice, but pass from the stomach soon after they have been received." One thing appears to have much surprised Dr. Beaumont, and that was, the degree to which St. Martin's system could be disordered without his being much inconvenienced by it. After drinking hard every day for eight or ten days, the stomach would show alarming appearances of disease; and yet the man would only feel a slight headache, and a general dulness and languor. If there is no comfort for drinkers in Dr. Beaumont's precious little volume, it must be also confessed, that neither the dissecting-knife nor the microscope afford us the least countenance. All that has yet been ascertained of the effects of alcohol by the dissection of the body favors the extreme position of the extreme teetotalers. A brain alcoholized the microscope proves to be a brain diseased. Blood which has absorbed alcohol is unhealthy blood,--the microscope shows it. The liver, the heart, and other organs, which have been accustomed to absorb alcohol, all give testimony under the microscope which produces discomfort in the mind of one who likes a glass of wine, and hopes to be able to continue the enjoyment of it. The dissecting-knife and the microscope so far have nothing to say for us,--nothing at all: they are dead against us.
