If any Spiritualist of our time really doubts that on this occasion there were _two_ girls, I invite him to read carefully Sir W. Crookes's account of the famous farewell scene. Katie proclaimed that her mission was over (she had converted a scientific man), and this was to be her last appearance. Florrie (who was in a trance, of course) wept, vainly implored her to visit this earth again, and sank, broken-hearted, to the floor. Katie directed Crookes--who stood, mute, with his phosphorus lamp in the middle of this pretty comedy--to see to Florrie, and, when he turned round again, Katie King had vanished for ever. That is to say, she had not been re-absorbed in the medium's body, as Spiritualist theory demands, but had _gone in the opposite direction while his back was turned_! Now there you have the most wonderful, classic, historic materialization in the whole Spiritualist history. It is attested by a distinguished man of science. It is endorsed by all the Spiritualist leaders of our time. And it is piffle from beginning to end. The evidence would not justify a man in drowning a mouse. The control was ridiculously inadequate. The imposture was palpable. If Sir W. Crookes had taken the scientific precaution of spreading a few tacks on the carpet, or waxing a bent pin in the ghost's chair, he would have heard the Hackney dialect at its richest. It was reserved for two Oxford undergraduates to show Sir W. Crookes how to investigate ghosts. They seized "Marie," Florrie's next spirit, in 1880; and they found they had in their arms the charming Florence, in her _lingerie_. Crookes had never searched the ample black velvet dress she used to wear. It is hardly worth while running over all the ghostly frauds since then, but a word about Florrie's friend and contemporary, Miss Showers, will be found instructive. Miss Showers was a really unpaid medium; though she received a good deal in the way of jewellery and other presents from admirers of her fair and aristocratic ghost, "Lenore Fitzwarren." She was a general's daughter, and above suspicion. No one dreamed of searching her. On one occasion she allowed Florence Cook to peep into her cabinet; and Florence--hawks do not pick out hawks' eyes--assured the public that she plainly saw Miss Showers and "Lenore," and even a second ghost, simultaneously. But, alas for the fair Lenore! Sergeant Cox, who was very sceptical, had Miss Showers at his country-house in 1874; and Miss Cox, a born daughter of Eve, tried to draw the curtain and peep into the cabinet. Miss Showers fought for her curtain, and the ghostly headdress fell off, and the game was up. This was only four months after the exposure of Florence Cook. The two most certainly genuine and respectable mediums in England were unmasked within four months. R. D. Owen's "Katie King" had been exposed in America in the previous year, the last sad year of the old man's life.
