1. I have no experience respecting distilled spirits; I regard them as highly dangerous, and have never used them except under medical advice, and then only in rare and serious cases of illness. 2. Beers and the lighter wines, if taken before mental work, always--in my experience--impair the working powers. They do not facilitate, but impede brain action. 3. After an exceptionally hard day's work, when the nervous power is exhausted, and the stomach is not able to digest and assimilate the food which the system needs, a glass of light wine, taken with the dinner, is a better aid to digestion than any other medicine that I know. To serve this purpose, its use--in my opinion-- should be exceptional, not habitual: it is a medicine, not a beverage. 4. After nervous excitement in the evening, especially public speaking, a glass of light beer serves a useful purpose as a sedative, and ensures at times a good sleep, when without it the night would be one of imperfect sleep. I must repeat that my experience is very limited; that in my judgment the cases which justify a man in so overtaxing his system that he requires a medicine to enable him to digest his dinner or enjoy his sleep must be rare; and that my own use of either wine or beer is very exceptional. Though I am not in strictness of speech a total abstinence man, I am ordinarily a water drinker. LYMAN ABBOT. March 11, 1882. MR. S. AUSTIN ALLIBONE, NEW YORK. I have no doubt that the use of alcohol as a rule is very injurious to all persons--authors included. In about 17 years (1853-1870), in which I was engaged on the "Dictionary of English Literature and Authors," I never took it but for medicine, and very seldom. Moderate smoking after meals I think useful to those who use their brains much; and this seems to have been the opinion of the majority of the physicians who took part in the controversy in the _Lancet_ about ten or twelve years since. An energetic non-smoker is in haste to rush to his work soon after dinner. A smoker is willing to rest (it should be for an hour), because he can enjoy his cigar, and his conscience is satisfied, which is a great thing for digestion; the brain is soothed also. S. AUSTIN ALLIBONE. March 27, 1882. THE DUKE OF ARGYLL, F. R. S. In answer to your question, I can only say that during by far the greatest part of my life I never took alcohol in any form; and that only in recent years I have taken a small fixed quantity under medical advice, as a preventive of gout. Tobacco I have never touched. ARGYLL. October 2, 1882. MR. MATTHEW ARNOLD.
