was impossible for the young lady to dress and act as a ghost without breaking the circuit. Yet under these conditions the spirit-form did appear, exhibited its arms, spoke, wrote, and touched several persons; and this happened, be it remembered, not in the medium’s own house, but in that of a private gentleman in the West End of London. For nearly an hour the circuit was never broken, and at the conclusion Miss Cook was found in a deep trance. Since this remarkable experiment Mr. William Crookes, F.R.S., has obtained, if possible, still more satisfactory evidence. He contrived a phosphorus lamp, and, armed with this, was allowed to go into the dark room accompanied by the spirit, and there saw and felt Miss Cook, dressed in black velvet, lying in a trance on the floor, while the spirit-form, in white robes, stood close beside her. During the evening this spirit-form had been for nearly an hour walking and talking with the company; and Mr. Crookes, by permission, clasped the figure in his arms, and found it to be, apparently, a real living woman, just as the skeptical gentleman had done. Yet this figure is not that of Miss Cook, nor of any other human being, since it appeared and disappeared in Mr. Crookes’s own house as completely as in that of the medium herself. The full statements of Messrs. Varley and Crookes, with a mass of interesting detail on the subject, appeared in the “Spiritualist” newspaper in March and April last; and they serve to show that whatever marvels occur in America can be reproduced here, and that men of science are not precluded from investigating these phenomena with scientific instruments and by scientific methods. In the concluding part of this paper we shall be able to show that another class of manifestation which originated in America—that of the so-called spirit photographs—has been first critically examined and completely demonstrated in our own country.
