159. I urged that the experiment was of immense importance, if considered as proving a spirit to be present, and to have actuated the apparatus; affording thus precise experimental proof of the immortality of the soul: that a matter of such moment should not be considered as conclusively decided until every possible additional means of verification should be employed.
160. This led my companions to accuse me of extreme incredulity. The medium said she “should not deem it worth while to sit for me again,” and one of the gentlemen sat himself down by the fireside, declaring me “to be insusceptible of conviction, and that he would now give me up.”
161. Nevertheless, the medium, relenting, gave me another sitting at her own dwelling a few days afterward; when I had improved the apparatus by employing two stationary weights by which the cord actuating the pulley, as in the drill-bow process, was made to pull it round by a horizontal motion of the table supported on castors, instead of the tilting motion.
162. The results confirmed those previously received, my father reporting himself again. He said that my mother and sister were with him, but not my brother. I inquired “if they were happy.” The disk revolved so as to bring the letter Y under the index, signifying the affirmation.
163. On the following week, I took my apparatus to the house of a spiritualist, where a circle was to meet. The apparatus being duly arranged, a lady whom I had never before noticed, and by whom my apparatus was seen for the first time, sat down at my table behind the screen. The spirit of an uncle who had left this life was invoked by this medium. Her invocation being successful, the spirit spelt his name out in full; other names were spelt out at request.
164. Although the requisite letters were ultimately found, there was evidently some difficulty, as if there was some groping for them with an imperfect light. This has been explained since by my father’s spirit. He alleges that preferably the eyes of the medium would be employed, but that, although with difficulty, he used mine as a substitute.
165. But although, with a view to convince the skeptical, spirits will occasionally give manifestations when the vision or muscular control of the medium is nullified, it is more difficult for them to operate in this way; moreover, it is more difficult for some spirits than for others.
166. Those spirits by whom I obtained my test manifestations were interested in my success. Others have refused to aid me in like manner. One who has assisted me with much zeal, has communicated that he would work my apparatus when arranged for a test; but, that as it caused much more exertion, and, of course, retardation, he advised that the test arrangement should not be interposed when it could be avoided.
167.[7]The table, at this stage of my inquiry, was not more than thirty inches in length. I had improved the construction in the following way:
168. Two of the legs were furnished with castors, through holes duly bored. Through perforations in the other two legs a rod was introduced, serving as an axle to two wheels of about five inches diameter. One of these wheels was grooved, so as to carry a band which extended around the pulley of the disk. Hence, pushing the table nine inches horizontally by the necessary rotation of the supporting wheels, caused the disk to make a complete revolution. It was while the table was of the size above mentioned, that I first saw the violent action to which they might be subjected without any corresponding or commensurate visible cause. The hand of the medium being laid on the table at about half-way between the centre and the nearest edge, it moved as if it were animated, jumping like a restive horse.
