222. Dr. W. F. Channing has since informed me that Mrs. Eustis’s account of these manifestations, as given to him, coincide with those given to him by me. 223. Sometime after this feat was performed through Mrs. Hayden, I inquired of my sister if she could not perform it through an excellent medium under whose influence communications were making at the time of this inquiry. It was replied that Mrs. Eustis being unconsciously to a certain extent a medium herself, the power of Mrs. Hayden was augmented by her presence. 224. But as respects the selection of letters without the assistance of the eyes of the medium, I have had many instances of this being done, although the facility of its performance is various, not only with different media and with different spirits, but likewise when the spirit and medium are the same: it varies with the state of the medium. I sat more than an hour with an accomplished medium, during an excessively hot evening, without receiving any communication; in consequence, as I supposed, of the effect of the heat upon her organism. 225. The interposition of water contained in a glass vase, upon the broad part of the lever actuating the index, so that the hands of the medium can touch nothing but the water, has an effect analogous to the lifting of the hand as above described, since the only difference in the conditions is, that in the one case there is air, in the other water, interposed. 226. It has been stated that, by the interposition of water, the power of actuating the index was paralyzed; yet merely warming the water enabled the manifestation to proceed, so as to empower the spirit to spell such names as were called for. (210.) 227. In one instance, I took a book from my pocket which the medium had never seen, and opened it at a page where the heading “Publisher’s Preface” was conspicuous, without allowing the medium to see any thing more than the back of the book. Holding the page exposed to the disk, the spirit spelt out “_Publish_—,” and then seemed unable to proceed. Meanwhile, the medium called to her little son to be quiet; forthwith the deficient letters, _ers_, were supplied, so as to finish the word “_Publisher’s_.” 228. The medium alleged that her mind was imbued with the idea that the word “publishing” was coming forth, and with a view to aid the spirit, lent some muscular aid to the letters necessary to complete that word; but attention to her child causing her mind to be withdrawn, the spirit immediately selected the letters above indited. On the same occasion I opened the same book, keeping the back toward the medium, opposite to an engraving of Jefferson: immediately, Jefferson was spelt out.
