Not infrequently a Materialized Spirit is seen to subside into the floor between the folds of the curtains at the opening of the Cabinet, This is termed ‘de-materialization,’ and not a little mystery is ascribed to it. The mystery vanishes when we reflect how easy it is for a lithe and active young woman so to bow down quickly, even to the very ground, as to convey the impression, when her white garments are alone visible against a black background, that she has sunk into the floor. I have at times distinctly felt the faint jar caused by the Medium’s falling backward within the dark curtains a little too hastily. At times, when the Spirit is wholly within the Cabinet, and visible only through the parted folds of the curtain, the semblance of a gradual sinking is obtained by simply uniting slowly the two folds of the black curtain, beginning at the head and gradually closing them down to the feet; the room is generally so dark that the dark curtain is indistinguishable at a little distance, and the effect of slowly falling is admirably conveyed. In one instance, where the Spiritual garments were not white, but particolored (the Spirit was a Scotch girl and wore the tartan), the effect of de-materializing was capitally given by the Spirit’s standing just inside the slightly parted curtains, and then allowing the whole outer costume, even to the head-dress, to fall swiftly to the floor. Perhaps the best effect in this line, that I have seen, was on one occasion when a Spirit had retired within the folds of the curtain, but apparently immediately reappeared again at the opening; she had been habited somewhat like a nun with white bands and fillets around the head and face; thus, too, was she clad at her reappearance, but, as I sat quite close to the Cabinet, I perceived that the figure was composed merely of the garments of the former Spirit, and that there was no face at all within the head-gear. I am sure the omission could not have been detected at the distance at which the rest of the circle sat. This snow-white figure was allowed to sink very, very slowly, the dark curtains uniting above it as it gradually sank, until only the oval white head-dress around what should have been a face rested for a few seconds on the very floor, and then suddenly collapsed. It was in the highest degree ingeniously devised and artistically executed.
