195. As through the influence of the medium, who sat at the table with us, communications had been received through my apparatus several times, the alphabet arranged from a state of disarrangement, and names spelt out by the revolution of the disk, it cannot be imagined that the medium could have influenced the alphabetical communications in this instance, since the medium, even if prone to deception, would have perceived it ridiculous to allege it impossible to work an apparatus which had on several occasions under her influence, proved the opposite to be true, in the presence of her father as well as myself. 196. It has been already mentioned in the narrative (164.) that my spirit father, and spirit friend W. W., had alleged that they worked my apparatus with great difficulty when under test conditions, from their great desire to make me a convert to Spiritualism. It was, therefore, quite consistent that a spirit, who had no such powerful motive, should have preferred to find an apology for not actuating my apparatus, rather than to have studied, or sought for the means of surmounting the obstacles. 197. As all the manifestations, observed on this occasion, were by the tilting or partial lifting of the table, I urged the spirit to aid me in obtaining a test that these manifestations came not from the medium, but from herself, a spirit. I immediately procured from a basket which I had previously brought to the premises, a brass ball, turned truly spherical, like a billiard ball, and a plate of zinc which had been ground quite true. I placed the ball on the table, the plate on the ball, and the hands of the medium on the plate. She had no other communication with the table than that which was thus established. Pressing on the ball when situated between perpendicular lines falling inside of all the legs of the table, would of course only press it downward more firmly on its feet. 198. Things being thus arranged, I solicited Maria to repeat the upward jerks which she had employed in the communication which she had been making. Her father joined his solicitation to mine, pointing out that my object was to obtain evidence, which would satisfy the scientific world that such manifestations were due to the agency of spirits. 199. After a little delay the table rose under the ball, the plate, and the hands of the medium, with greater force than had been displayed in any of the foregoing movements. 200. Subsequently, being in company with Maria’s father, at the dwelling of a spiritualist, and sitting with a medium at the table supporting an apparatus for alphabetical communications, the spirit of Maria, who seems to follow her worthy father with much filial affection, reported herself. I inquired whether she remembered our previous meeting, and what means I resorted to as a test. She replied, “You used a plate and ball to support the hands of the medium, which I knocked away.”
