In reply to your letter of the 7th February, I have the honour to recall you the opinion which is current to-day among doctors of the highest authority, namely, that the abuse of alcohol and tobacco offers the greatest inconvenience from the point of view of health. Alcoholism produces a state of disorder of the organism to which a great number of maladies attach themselves. It is not a question of the moderate use of excitants, but the limit between use and abuse is difficult to trace, because it varies according to the country, the climate, and the habits of the individual constitution. A. WURTZ. March 14, 1882. APPENDIX. DR. RISDON BENNETT. "There are few people, I believe, who are aided in the actual performance of brain-work by alcohol; not that many, nay, most persons, are not rendered more ready and brilliant in conversation, or have their imagination quickened for a time. But the steady, continued exercise of the mental powers demanded of professional men is more often impeded than aided at the time by alcohol." _Contemporary Review_, vol. 34, p. 343. THE REV. STOPFORD A. BROOKE, M. A. "It has been said that moderate doses of alcohol stimulate work into greater activity, and make life happier and brighter. My experience, since I became a total abstainer, has been the opposite. I have found myself able to work better. I have a greater command over any powers I possess. I can make use of them when I please. When I call upon them, they answer; and I need not wait for them to be in the humour. It is all the difference between a machine well oiled and one which has something, among the wheels which catches and retards the movement at unexpected times. As to the pleasure of life, it has been also increased. I enjoy Nature, books, and men more than I did--and my previous enjoyment of them was not small. Those attacks of depression which come to every man at times who lives too sedentary a life rarely visit me now, and when depression does come from any trouble, I can overcome it far more quickly than before. The fact is, alcohol, even in the small quantities I took it, while it did not seem to injure health, injures the fineness of that physical balance which means a state of health in which all the world is pleasant. That is my experience after four months of water-drinking, and it is all the more striking to me, because for the last four or five years I have been a very moderate drinker. However, the experience of one man is not that of another, and mine only goes for what it is worth to those to whom, as much alcohol as is contained in one glass of sherry, or port, alters away from the standard of health. I have discovered, since abstinence, that that is true of me. And I am sure, from inquiries, I have made, that it is true for a great many other people who do not at all suspect it. Therefore, I appeal to the young and the old, to try abstinence for the very reasons they now use alcohol--in order to
