862. It is not in reference to this distinguished physician in his individual capacity that I name him thus often, but in reference to the hypothesis which his allegations must oblige him to sustain, and of which he may be considered a most respectable advocate. Dr. Bell not only admits, but confirms by his own testimony, the important fact of the movement of heavy bodies without contact. His experience, in this respect, is more striking than mine, since he has not only seen this phenomena take place repeatedly, but on one occasion, as before stated, saw tables move _fifty_ feet, intelligently obedient to his directions. He also admits the reception of such communications from pretended spirits, as spiritualists would consider as coming from real spirits. Yet on the negative ground, that _agreeably to his experience, nothing was found to be communicable_ but what pre-existed in the mind of some mortal present, he infers that the ideas received are not derived from spirits, but from the minds of those mortals who are parties to the process. 863. Of course our distinguished friend thus involves himself in the task of explaining not only the intellectual, but also the mechanical movements, by the mental agency of the media who participate in the conditions under which the manifestations occur. 864. I have already adduced manifestations irreconcilable with the assumption on which the whole of Dr. Bell’s inference is built, (111 to 288.) But were his observations verified, in order to make them justify the abnegation of spirits, it should be shown that any spirit could tell him _any_ thing which must be known to him, whether known to the spirits or not. Remembering all the facts communicated to him by his spirit brother, it should be shown that any other spirit could narrate them as well as his spirit brother. Any inquiry made of _any_ spirit, _of which the answer is known to the inquirer_, should be told on request as well as any other; but it will be found that answers are given only to those of which the spirit knows the answers independently, through his own memory. Under favourable circumstances mental questions are answered; but often, when mental questions cannot be answered, those put verbally are replied to. I have detected spirit impostors, by their inability to tell the name of my sister in the spheres. 865. I postponed the discussion on this question until I should have submitted to the reader the communications which I had received. I trust that these are of a nature to show that they could not have originated in my mind, nor in those of the media through whom they were obtained.
