The mediumship of this lady is so well known, and has been so universally attested, that nothing I can write of could possibly add to her fame; and as I made her acquaintance but a short time before she relinquished sitting for manifestations, I have had but little experience of her powers, but such as I enjoyed were very remarkable. I have alluded to them in the story of "The Green Lady," whose apparition was due solely to Mrs. Guppy Volckman's presence, and on that occasion she gave us another wonderful proof of her mediumship. A sheet was procured and held up at either end by Mr. Charles Williams and herself. It was held in the light, in the centre of the room, forming a white wall of about five feet high, _i.e._, as high as their arms could conveniently reach. _Both_ the hands of Mrs. Volckman and Mr. Williams were placed _outside_ the sheet, so that no trickery might be suspected through their being concealed. In a short time the head of a woman appeared above the sheet, followed by that of a man, and various pairs of hands, both large and small, which bobbed up and down, and seized the hands of the spectators, whilst the faces went close to the media, as if with the intention of kissing them. This frightened Mrs. Volckman, so that she frequently screamed and dropped her end of the sheet, which, had there been any deception, must inevitably have exposed it. It seemed to make no difference to the spirits, however, who reappeared directly they had the opportunity, and made her at last so nervous that she threw the sheet down and refused to hold it any more. The faces were life-size, and could move their eyes and lips; the hands were some as large as a man's, and covered with hair, and others like those of a woman or child. They had all the capability of working the fingers and grasping objects presented to them; whilst the four hands belonging to the media were kept in sight of the audience, and could not have worked machinery even if they could have concealed it.
