"I once saw Read" (a well-known medium for physical manifestations) "affected by the abrupt introduction of light at one of his circles in Boston, at which he was, as usual, securely tied by a committee chosen by the audience, and fastened securely to his chair. The manifestations were after the common order, and went on harmoniously until an Indian war-song and dance were inaugurated. The exhibition was very exciting, and both the song and the dance became so uproarious and violent that, although we were in a three-story back room, I was apprehensive that not only the temporary platform might give way, but that the attention of the police might be attracted to the spot by the noise. Near by me sat Miss F., an excellent clairvoyant medium, who was earnestly describing to some of her friends the scene that was being enacted on the platform. She stated that two powerful Indians stood by Read, and that it was he who performed the wonderful dance.... Thus one of the best 'dark-circle mediums in the United States' was not only proved to be an 'impostor,' but taken in the very act of his trickery.... From all that was occurring before us, it was too evident that Read was an impostor; for 'Miss F. clairvoyantly saw him perform tricks which he palmed off on the public as spiritual.'... But now, ... mark the sequel, and observe how easy it is for those who suffer their zeal to outrun their knowledge to be mistaken; and how true it is that as spiritual things can only be discerned by the spiritual eye, and material things only by the material eye, so the spiritual eye can (under ordinary circumstances) discern only spiritual things, as the material eye can discern only material things. "It seems that a self-lighting burner had been adjusted near the platform, at which an experienced man from the gas-works was stationed, with the gas-cock in his hand, ready at a moment's notice to turn on the light. This man was within hearing distance of Miss F., and must have heard her remarks;... he gave the cock a sudden turn, and in an instant all was light, and of course the medium was--_exposed_--sitting fast bound in his chair, with every knot as perfect as when first tied, but in a dying condition from the effect of the tremendous shock his nervous system underwent by the sudden return of the unusual volume of elements that had been extracted from his physical body to furnish material clothing for his own _double_, or some other spiritual creation, that was performing the exhausting war-song and dance on the platform; nor is it probable that Miss F. ever saw the _material_ body of Read during the whole time she _clairvoyantly_ saw him.... Suffice it to say, that the suffering medium was released from his bonds as soon as practicable, but not until after three or four minutes had expired, ... after which, by the application of restoratives, Read was gradually revived, and restored to his right mind and condition."
