For the Cincinnati Gazette.A TEST OF MESMERISM.rinl e'DITORS:—I discover from a late edito-wise e a Sreat number of thepe:ibihim to establish the truthgreotcteairc to see him put an* Jcf.C11 * Plt;** son of Erin inoa one side. He then stated h« Jjf left undisturbed he would remain three d*yl Without change of position. That at the end of three days he would turn round, and remain in that position three days more, when he would awake to the minute just six days hom the time he was put in the mesmeric state.” My proposition is thto—fifty dollars to the poor Irishman will be a great object, and in the experiment he will suffer no pain. To leave you no ground for cavil, you shall select two persons to watch the man whilst in the mesmeric state, and if the experiment fully succeeds, jrou shall pay the expenses, if not, that they be paid by the Professor. You are cornered at last, gentlemen, and must risk the experiment. Of the truth of the theory there can be no tfdubt, and to satisfy you and all other doubters, I will add to your $50 to the poor Irishman, $50 more, and a gold medal of like value to the Professor, for proving the truth of mesmerism beyond cavil os well as his claim to public confidence.24th Sept., 1844. A CITIZEN.Our correspondent is a responsible man, and we agree to his proposition so far as we are concerned.—Cincinnati Gazette. i
