156. “Will the spirit do us the favour to give the initials of his name?” The letters R H were successively brought under the index. “My honoured father?” said I. The letter Y was again brought under the index. 157. “Will my father do me the favour to bring the letters under the index successively in alphabetical order?” Immediately the disk began to revolve so as to produce the desired result. After it had proceeded as far as the middle of the alphabet, I requested that “the name of Washington should be spelt out by the same process.” This feat was accordingly performed, as well as others of a like nature. 158. The company consisted of but few persons besides the medium, who now urged that I could no longer refuse to come over to their belief. Under these circumstances the following communication was made by the revolving of the disk: “_Oh, my son, listen to reason!_” 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.
