For the benefit of the uninitiated, let me begin by telling _who_ "Katie King" was supposed to be. Her account of herself was that her name was "Annie Owens Morgan;" that she was the daughter of Sir Henry Morgan, a famous buccaneer who lived about the time of the Commonwealth, and suffered death upon the high seas, being, in fact, a pirate; that she herself was about twelve years old when Charles the First was beheaded; that she married and had two little children; that she committed more crimes than we should like to hear of, having murdered men with her own hands, but yet died quite young, at about two or three and twenty. To all questions concerning the reason of her reappearance on earth, she returned but one answer, That it was part of the work given her to do to convince the world of the truth of Spiritualism. This was the information I received from her own lips. She had appeared to the Cooks some years before I saw her, and had become so much one of the family as to walk about the house at all times without alarming the inmates. She often materialized and got into bed with her medium at night, much to Florrie's annoyance; and after Miss Cook's marriage to Captain Corner, he told me himself that he used to feel at first as if he had married two women, and was not quite sure which was his wife of the two. The order of these _séances_ was always the same. Miss Cook retired to a back room, divided from the audience by a thin damask curtain, and presently the form of "Katie King" would appear dressed in white, and walk out amongst the sitters in gaslight, and talk like one of themselves. Florence Cook (as I mentioned before) is a very small, slight brunette, with dark eyes and dark curly hair and a delicate aquiline nose. Sometimes "Katie" resembled her exactly; at others, she was totally different. Sometimes, too, she measured the same height as her medium; at others, she was much taller. I have a large photograph of "Katie" taken under limelight. In it she appears as the double of Florrie Cook, yet Florrie was looking on whilst the picture was taken. I have sat for her several times with Mr. Crookes, and seen the tests applied which are mentioned in his book on the subject. I have seen Florrie's dark curls _nailed down to the floor_, outside the curtain, in view of the audience, whilst "Katie" walked about and talked with us. I have seen Florrie placed on the scale of a weighing machine constructed by Mr. Crookes for the purpose, behind the curtain, whilst the balance remained in sight. I have seen under these circumstances that the medium weighed eight stone in a normal condition, and that as soon as the materialized form was fully developed, the balance ran up to four stone. Moreover, I have seen both Florrie and "Katie" together on several occasions, so I can have no doubt on the subject that they were two separate creatures. Still, I can quite understand how difficult it must
