M. L. P. GUENIN, REVISING STENOGRAPHER TO THE FRENCH SENATE.
I thank you for having asked my opinion upon the effects of tobacco and alcohol on the mind and the health of men who give themselves up to intellectual work; and hasten to comply with your request. I am not a very resolute adversary of tobacco, because I must admit that I smoke, and at home use wine also: but if their use appears useful or agreeable, I ought to add that whenever I have to undertake any long arduous work, and above all, the reproduction of stenographic law or parliamentary reports, of which the copy is required without delay, I then make use of nothing but pure water. I limit myself as to stimulant to the use of coffee, which enables me to pass whole days and nights without feeling any want of sleep and, so to say, without fatigue, notwithstanding the labour of the stenographic translations. As you see, I consider that tobacco and alcohol do not act as stimulants, but rather as narcotics. With me they induce after the first moment of excitement a sort of calm and somnolence altogether incompatible with severe work; and I prefer coffee, always on the condition that as soon as the effort to be accomplished is finished the use of it must cease. I will not invoke the precedents of the celebrated men who have been led to make great use of coffee without impairing their health. It is after many years' experience that I have acted as I have indicated.
L. P. GUENIN.

DR. WILLIAM GUY.
In answer to your enquiry, I may state the result of my personal experience and observation thus :-1. Alcoholic liquors, when taken in such quantity as to excite the circulation, are unfavourable to all inquiries requiring care and accuracy, but not unfavourable to efforts of the imagination. 2. Tobacco taken in small quantities is not unwholesome in its action on mind or body. When taken in excess it is not easy to define or describe its action, the chief fact relating to it being that it increases the number of the pulse, but lessens the force of the heart. 3. My personal experience of such quantities of wine as two or more glasses of port a day at my age (72) is that it produces no perceptible or measurable effect when taken for, say, three weeks or a month at a time, when compared with the like period of total abstinence. 4. It may be said in favour of temperance or even of extreme abstinence, that some of those men who have done most work in their day—John Howard, Wesley, and Cobbett, for example—have been either very moderate, or decidedly abstemious. But on the other hand, such men as Samuel Johnson, who was a free liver and glutton, and Thackeray, who drank to excess, have also got through a great amount of work.

PROFESSOR ERNST HAECKEL, JENA.
I find strong coffee very useful in mental work. Of alcohol, I take very little, because I find it of no value as a stimulant. I have never smoked.
