You know how very deaf I am, and do not therefore need to be reminded that one should trust scarcely more to what a deaf man hears than to what a blind man sees. Wherefore, I want you, for my sake, and that the Committee may feel sure of their ground, to confirm in writing what you have more than once said to me, namely, that the Committee must conform to the conditions which the Spirits impose; that you cannot consent to submit to any tests, and that rather than do so you will return at once to New York; that we must accept the manifestations as given by the Spirits; and that, since these manifestations are the result of a gradual growth, it is impossible, in the space of six séances, to repeat or to verify Professor Zoellner's experiments; and, lastly, that, if on your return to New York, the Spirits so authorize it, you will be willing, if desired, to make arrangements for another series of séances with us of a higher order of manifestations. I remain respectfully, Your obedient servant, HORACE HOWARD FURNESS, _Acting Chairman Seybert Commission_. No. 11 E. 13th Street, N.Y., February 4th, 1885. DEAR MR. FURNESS:--I take this opportunity to express to you, and through you to the other members of the Seybert Commission, my hearty approval of the course pursued by them in their investigation of phenomena occurring in my presence. Fully realizing that I am only the instrument or channel through which these manifestations are produced, it would be presumption on my part to undertake to lay down a line to be followed by the unseen intelligences, whose servant I am. Hence, I did say their conditions must be acceded to or I would return to New York. That they did so, is evident to my mind from the results obtained, which I regard as a necessary preliminary to a continuation, when other experiments may be introduced with better prospects of success. It may be well not to insist on following the exact course pursued by Professor Zoellner, but leave it open to original or impromptu suggestions that may be adopted without previous consideration, which, if successful, would be of equal value as evidence of its genuineness, at the same time give greater breadth to the experiments. In conclusion, allow me to say that in the event of the Committee desiring to continue these experiments through another series of sittings with me, it will give me pleasure to enter into arrangements for that purpose. Very truly yours, HENRY SLADE. * * * * * February 13th, 1885.
