No Spiritualist can quarrel with me for dwelling on this famous materialization. It is supposed to be the mostly firmly authenticated in the whole movement. Sir W. Crookes said, quite late in life, that he had "nothing to retract"; and every Spiritualist who quotes his high authority endorses the materialization of Katie King. The majority of the public to-day will merely conclude that some scientific men are worse witnesses on such matters than dockers, and that the disgust of scientific men like Sir E. Ray Lankester and Sir Bryan Donkin has a very solid foundation. Even at the time there were leading Spiritualists like Sergeant Cox who regarded the affair with bewilderment and suspected that all materializations were fraud. What can be said for Sir W. Crookes? He alleges that the medium and the ghost were unmistakably different persons. Katie King was taller than Florrie. But Florence Cook, like her contemporary, Miss Showers, was seen to walk on tip-toe, and alter her stature, when she was the ghost. Sir W. Crookes nowhere says that he took the elementary precaution of measuring ghost and medium _with their dresses drawn up to their knees_. He says that the lock of hair which Katie gave him as a memento was auburn, and Florrie's hair was very dark brown. But we do not doubt that on the _last occasion_ the ghost was _not_ Florence Cook. Other differences he finds, in a dim light, are negligible. If the modern Spiritualist really believes Sir W. Crookes, as he professes to do, he must come to this ultra-miraculous conclusion: The spiritual powers in this case did not merely take _some_ matter out of Florence Cook's body, but they took more than the whole substance of it, because Crookes says that Katie was taller and broader than Florrie! And, to cap this supreme miracle, he on one occasion saw ghost and medium together, and apparently Florrie was as solid as ever! The spirits had in this case multiplied nine stone into eighteen or nineteen. After twenty years of religious controversy I am a patient man, but I decline to argue with any one who doubts that Florrie Cook (four times caught in fraud, and a pupil of Herne) impersonated the ghost. Mr. F. Podmore saw the photographs which Professor Crookes took. He says that ghost and medium are the same person. Crookes himself was nervous, in spite of Florrie's charms, and he begged to be allowed to see ghost and medium plainly together. The artful Florence could not manage that in his house. Once she let him look at her, lying on the ground, but he saw no face or hands; and a bundle of clothes and a pair of boots are not quite clearly a living person. He pressed again. Florence--he tells us this very naively--borrowed his lamp (a bottle of phosphorized oil) and tested its penetrating power, and then told him he should see both ghost and medium in _her_ house. He went, and we are not surprised that he saw them.
