A small centre-table suddenly moved up of its own accord to the table by the side of the medium, as if it had gradually got within the sphere of a strong attractive force. Afterwards, at our request, it was thrown down on the floor without any person touching it, and it then moved about in a strange life-like manner, as if seeking some means of getting up again, turning its claws first on one side and then on the other. On another occasion, a very large leather arm-chair which stood at least four or five feet from the medium, suddenly wheeled up to her, after a few slight preliminary movements. It is, of course, easy to say that what I relate is impossible. I maintain that it is accurately true; and that no man, whatever be his attainments, has such an exhaustive knowledge of the powers of nature as to justify him in using the word "impossible" with regard to facts which I and many others have repeatedly witnessed. We evidently have here facts similar to those which I observed in my experiments with Eusapia and with other mediums. Alfred Russel Wallace continues his account by the citation of cases analogous to those which have been described in this work; then sums up the experiments of Crookes, of Varley, Morgan, and other English scientists; does me the honor of citing my letter to the Dialectical Society which I have printed above; passes in review the history of Spiritualism, and declares that (1) _the facts are incontestable_, and that (2), in his opinion, the best explanatory hypothesis is that of _spirits_, or _the souls of the disembodied_--the theory of "the unconscious" being _evidently inadequate_. Such is also the opinion of the electrician Cromwell Varley. Neither he nor Wallace believes that there is anything supernatural in the phenomena. Discarnate spirits are in nature, as well as the incarnate. "The triviality of the communications ought not to astonish us, if we consider the myriads of trivial and fantastic human beings who every day become ghosts and are the same beings the day after their death that they were the day before."
