"It is true that Byron assumes in his poetry the character of a _debauche_, and says he wrote Don Juan under the influence of gin and water. But much of that sort of talk is merely for stage effect, and we see how industrious he was, and read of his training vigorously to reduce corpulence, and of his being such an exceptionally experienced swimmer as to rival Leander in crossing the Hellespont.... The machinery of sensitive souls is as delicate as it is valuable, and cannot bear the rough usage which coarse customs inflict upon it. It is broken to pieces by blows which common natures laugh at. The literary man, with his highly-cultivated, tightly-strung sensations, is often more than others susceptible of the noxious, and less susceptible of the beneficial results of alcohol. His mind is easier to cloud, and there is a deeper responsibility in clouding it.... Equally when we descend into the lower regions of Parnassus, the abodes of talent and cleverness, and the supply of periodical literary requirements, we find the due care of the body absolutely essential to the continued usefulness of the intellect. The first thing to which one entering the profession of literature must make up his mind is to be healthy, and he can only be so by temperance.... Tobacco should not be indulged in during working hours. Whatever physiological effect it has is sedative, and so obstructs mental operations." _Manual of Diet in Health and Disease_. 1876, p. 162. PROFESSOR THOMAS R. FRASER, EDINBURGH. "The stimulating action on the brain of quantities far short of intoxicating, is accompanied with a paralysing action which seems most rapidly and powerfully to involve the higher faculties. Mental work may seem to be rendered more easy, but ease is gained at the expense of quality. The editor of a newspaper will tell you that, if he has been dining out, he cannot with confidence write a leading article until he has allowed sufficient time to elapse from the effect of the wine he has drunk, in moderation, to pass away; and even the novelist, whose brain-work is in the regions of imagination, will relate a similar experience.... In a person accustomed to the use of tobacco the intellectual work is difficult when smoking cannot be indulged in, the mind cannot easily be concentrated on a subject, and unrest is produced--but this disappears when recourse is had to smoking; and probably some of its reputation as a soothing agent has on this account been acquired. The circulation is also a little excited, and no doubt this assists in rendering brain work more easy. In a short time, however, the circulation is slightly depressed, the pulse becoming smaller; and this may assist in producing the soothing effect generally experienced." _The Use and Abuse of Alcoholic Stimulants and Tobacco_. 1881 HUBERT HERKOMER, A.
