854. I requested the medium to pick up a pair of scissors which lay on the table, and, while holding the blades between the finger and thumb, to lay the rings upon the back of my hand. An increase of power was manifested to my observation and that of W. W. 855. At a subsequent sitting, having made due preparation, a strip of sheet tin about two inches wide, and about fifteen inches in length, being applied to the back of my hand while resting on the base board of the spiritoscope, (Plate 4, Fig. 2,) the medium held it successively at various distances. Under these circumstances, the facilitation was greater as the distance between her hand and mine was diminished. 856. A plate of glass of about four inches square, interposed between the palm of the hand of the medium and the back of mine, interrupted the power entirely; but neither cork nor a metallic plate of a similar size much reduced the power. 857. The frame (Fig. 3, Plate 4) being _in situ_, as described, paragraph _kk_ of the description, under these circumstances the removal of the serrated strips diminished the power more and more as removed. 858. Thus it appears that there is a mesmeric electricity, or spiritual electricity, which may be considered as appropriate to the spirit world as their vital air is; but which like that air, may influence our spiritual bodies while in their mundane tenement. It may, as well as the vital air of the spirit world, belong in common to the inhabitants of that world and to us as spirits, being a polarizing affection of the spiritual ethereal medium, of which the undulations constitute the peculiar rays of their spiritual sun. 859. That this spiritual or mesmeric electricity should be auxiliary to the efficacy of the magic will-power, of spirits, is of course one of those mysteries which, like that of gravitation, may be ascertained to prevail, and yet be to spirits as well as mortals inexplicable. 860. We live in a wonder-working universe, which becomes more and more wonderful as we learn more of it, instead of being brought more within our comprehension. When we compare what we know with the knowledge of savages, it may appear a mountain of learning and science; but this very learning and science only makes us see still more how great is our ignorance! ON PSYCHOLOGICAL EXPLANATIONS OF SPIRITUAL MANIFESTATIONS. 861. This, for the third time, brings under discussion the report of Dr. Bell, of Somerville, near Boston, on spiritual manifestations.
