Let us for a moment examine the facts in this Crookes' episode. A small book exists which describes them, though it is not as accessible as it should be. In these wonderful experiments, which extended over several years, Miss Florrie Cook, who was a young lady of from 16 to 18 years of age, was repeatedly confined in Prof. Crookes' study, the door being locked on the inside. Here she lay unconscious upon a couch. The spectators assembled in the laboratory, which was separated by a curtained opening from the study. After a short interval, through this opening there emerged a lady who was in all ways different from Miss Cook. She gave her earth name as Katie King, and she proclaimed herself to be a materialised spirit, whose mission it was to carry the knowledge of immortality to mortals. She was of great beauty of face, figure, and manner. She was four and a half inches taller than Miss Cook, fair, whereas the latter was dark, and as different from her as one woman could be from another. Her pulse rate was markedly slower. She became for the time entirely one of the company, walking about, addressing each person present, and taking delight in the children. She made no objection to photography or any other test. Forty-eight photographs of different degrees of excellence were made of her. She was seen at the same time as the medium on several occasions. Finally she departed, saying that her mission was over and that she had other work to do. When she vanished materialism should have vanished also, if mankind had taken adequate notice of the facts. Now, what can the fair-minded inquirer say to such a story as that--one of many, but for the moment we are concentrating upon it? Was Mr. Crookes a blasphemous liar? But there were very many witnesses, as many sometimes as eight at a single sitting. And there are the photographs which include Miss Cook and show that the two women were quite different. Was he honestly mistaken? But that is inconceivable. Read the original narrative and see if you can find any solution save that it is true. If a man can read that sober, cautious statement and not be convinced, then assuredly his brain, is out of gear. Finally, ask yourself whether any religious manifestation in the world has had anything like the absolute proof which lies in this one. Cannot the orthodox see that instead of combating such a story, or talking nonsense about devils, they should hail that which is indeed the final answer to that materialism which is their really dangerous enemy. Even as I write, my eye falls upon a letter on my desk from an officer who had lost all faith in immortality and become an absolute materialist. "I came to dread my return home, for I cannot stand hypocrisy, and I knew well my attitude would cause some members of my family deep grief. Your book has now brought me untold comfort, and I can face the future cheerfully." Are these fruits from the Devil's tree, you timid orthodox critic?
