Another instance. A lady was writing automatically by means of the planchette. I was trying to devise a means of proving that what she wrote was not due to "unconscious cerebration." The planchette, as it always does, insisted that, although it was moved by the hand and the arm of the lady, the _intelligence_ was that of an invisible being who was playing on her brain as on a musical instrument, and thus moving her muscles. I therefore said to this intelligence, "Can you see the contents of this room?" "Yes," wrote the planchette. "Can you see to read this newspaper?" said I, putting my finger on a copy of the _Times_, which was on a table behind me, but without looking at it. "Yes," was the reply of the planchette. "Well," I said, "if you can see that, write the word which is now covered by my finger, and I will believe you." The planchette commenced to move. Slowly and with great difficulty the word "however" was written. I turned round and saw that the word "however" was covered by the tip of my finger. I had purposely avoided looking at the newspaper when I tried this experiment, and it was impossible for the lady, had she tried, to have seen any of the printed words, for she was sitting at one table, and the paper was on another table behind, my body intervening. THIRTEENTH CLASS: _Miscellaneous Occurrences of a Complex Character._ (Professor Crookes here cites two examples of the _transference of matter through matter_,--a bell passing from neighboring room into that in which the seance was being held, and a flower separating from a bouquet and _passing through the table_.) The spare at my disposal will not permit me to give more details here; but all my readers must appreciate, as I do, the importance of these experiments of the eminent chemist. I will especially call attention to the proofs they afford of the presence of a mind or intelligence, other than that of the experimenters; to the formation of hands and spirit-forms; and to the passage of matter through matter.
