. ALL THE CLAIMS made by 4 Frenchman for his recent discovery are correct, “tobacco heart” and all the kindred evils that follow the excessive wooing of “My Lady Nicotine” will be banished forever from the earth. M. Gerald is the discoverer, or claims to be the discoverer, of a preparation which, while retaining all the nicotine in tobacco, still renders it absolutely harmless. It is asserted that the flavor of the weed is improved, rather than injured, which is in direct and happy opposition to all previous ‘methods of denicotization. — The Revue Scientifique, Paris, says that “the tobacco leaves are treated with a solution of tannic acid, which fixes the alkaloids in such a manners that the nicotine and essences of the plat are neutralized and rendered harmless. It appears that this does not destroy the flavor of the tobacco, but to reproduce the perfume dam aged by the tannic the tobacco is dipped in a decoction prepared with the plant origanum vulgare.” It should be explained that origanum vulgare is a pliant of the mint family, the odor of which is peculiarly aromatic and fragrant. In order to test the practical value of his experiments, M. Gerold used fif ty habitual smokers between the ages of 22 and 24 years. He found that after the use of cigars of the regulation kind there was a lowering of the arterial pressure and an enfeebling of the pluse. When cigars dipped in M., Gerald's preparation were used the arterial pressure and the pulse showed no mod ification whatever. The scientist also used frogs in his test. . He injected an active tobacco infu sion under the skin of one. imme diately a state of apathy ensued. and in twenty minutes complete catalepsy from which the frog slowly recovered. The same amount of an infusion from the prepared tobacco was injected and the only result was a brief period of lassitude, beginning after ten minutes had expired. It is asserted that nobody can tell the difference between a gre pared and an unprepared cigar of the same quality, but there are no after effects from the former. For instance, M. Gerald smoked fif teen prepared cigars in a single day without evil results, although he had never been able to smoke more than three or four of the regulation kind in the same period. A prepared cigar smoked by a boy, who had olways been made ill by tobacco, failed to cause him the slightest qualm. M. Gerald’s exper iments will prove of decided interest to smokers and to tobacco dealers gen erally. If his preparations can be put on the market cheaply they may revo lutionize the industry.
