"The feats of the ancient jugglers were many of them mere acts of deception. They were known to be such by those who performed them. And the same is true of many who practise the like things now. Their rappings and writings, and other strange performances, are secretly, artfully got up by themselves. I do not say that this is true in all cases; but in some cases we _know_ it is true; because the matter has been fully investigated, and public confession has been made. For example: A young woman, who had been instructed by the Rochester rappers, and practised the art with them for a time, afterwards renounced it, and exposed the delusion to the world. 'All who saw her and heard her,' says my informant, 'were entirely satisfied of the truth of her statements, and that she had revealed the actual method in which the deception was effected and the deluded were blinded. Another young woman in Providence, Almira Beazely, who was noted for her rappings and revelations, and who murdered her brother to accomplish one of her own predictions, confessed, on her trial, that she made the noises herself, and explained the manner in which they were produced. She also confessed to the removal of certain articles in the house which had strangely disappeared, and which she pretended had been _taken away by spirits_. Drs. Lee and Flint, of Buffalo, assisted by two gentlemen by the name of Burr, have very thoroughly investigated the matter, and explained the manner in which the mysterious noises are made. Mr. Burr has himself made the rappings, and made them so loud as to be heard by a congregation of fifteen hundred people. "These instances are sufficient to prove that the spiritual manifestations of our times, like those of ancient times, are in many instances a sheer deception--a vile trick, palmed off upon a wondering and credulous community, for the sake of money, or for other sinister and selfish ends. If there is any thing more than trick in these spiritual manifestations,--and I am inclined to think that, in some instances, there may be,--I should refer it, as in case of the ancient wizards, to the influence of _occult natural causes_--perhaps electricity, or animal magnetism, or something else, operating upon a nervous system of peculiar sensibility. I incline to this opinion for several reasons. "In the first place, if the noises and other manifestations were really the work of spirits, why should they not be made through one person, as well as another? Why should not all mediums be alike? Whereas it is confessed that only persons of a peculiar nervous temperament are capable of becoming mediums.
