“Hope stood on my left hand for the whole time in the dark room and I kept the box of plates under my right elbow during the operations of initialling and inserting the plates in the slides.... My own camera remained closed in my despatch-case (also closed) till I returned from the dark room, when I set it up on its tripod, extending it, and focussing it upon the chair afterwards used. When the exposures were made by Hope I had to explain to him how to actuate the shutter, as the lever on the camera front was new to him. The only contact with the camera was when he touched this lever. Exposure thirty-five seconds. Neither Mrs. Buxton nor Hope knew that I had intended using my own camera and dark slides till we met in the studio. These slides are metallic and each contains one plate.” [Illustration: FIG. 5.—Group of Members of the S.S.S.P. The psychic face will be seen in the centre of the plate and situated horizontally to the sitters. (_See_ p. 28.)] [Illustration: FIG. 6.—Major R. E. E. Spencer and psychic face obtained in special test. (_See_ p. 31.)] [Illustration: FIG. 7.—Sir William Crookes with psychic face obtained in his own laboratory through the mediumship of the Crewe Circle. (_See_ p. 33.)] (For the benefit of the uninitiated, let me explain that the carrier and the dark slide are different names for the same thing, the receptacle into which the plates are put in the dark room, which is then inserted into the back of the camera.)
