But Howard the philanthropist assures us, that it had efficacy neither in preventing the hospital fever, nor in warding off the deadly plague. Dr. Rush says, that at Philadelphia it was equally ineffectual, in preserving its votaries from influenza and yellow fever. Excuse ourselves as we may, it is at best a disgusting habit, persisted in against the convictions of our understanding and the dictates of true politeness, and adapted only to gratify a vitiated and unnatural appetite. It is, indeed, agreeable to observe, that the superior refinement and regard to good manners, in some parts of the old world, have at length awakened public sentiment on this subject. We are informed by travellers, that smoking is disallowed in taverns and coffee-houses in England, and that taking snuff is becoming unfashionable and vulgar in France. How much is it to be lamented, that, while the use of tobacco is thus declining in two of the most enlightened countries in Europe, it is daily becoming more general in America! "In no one view," says Dr. Rush, "is it possible to contemplate the creature man in a more absurd and ridiculous light, than in his foolish and disgusting attachment to the poisonous weed, tobacco." Who then can witness groups of boys ten or twelve years old in our streets, smoking cigars, without anticipating such a depreciation in our posterity with regard to health and character, as can scarcely be contemplated without pain and horror! * * * * * After the foregoing was in type, it was submitted to Doctor Warren, of this City, with a request that he would examine the whole, carefully, and give his opinion of it. He has kindly returned the following strong testimonial in favor of the Dissertation, which cannot but secure it a wide circulation, and the attentive perusal of every man who values health. DEAR SIR-- In compliance with your request, I have read over the pamphlet of Dr. McAllister on the use of Tobacco. Though my present occupations have prevented my doing it so carefully, as to entitle me to suggest any alteration or improvement.
