"No matter what he thought," I replied. "Any paper by a man of Crookes's standing, with his knowledge of chemistry and of life, and his long training in exact observation, should have been considered. The action of the secretary was due simply to prejudice, and many of those who voted to ignore that report are to-day more than half convinced that Sir William has been justified. Each of his experiments has been repeated and his findings verified by scientific men of Europe. It is a pleasure to add that our own Smithsonian Institution published two of his speculative papers some years ago. So it goes--the heresy of to-day is the orthodoxy of to-morrow." "Didn't Crookes afterward repudiate that early report?" asked Miller. "On the contrary, in 1898, upon being elected to the presidency of the British Association for the Advancement of Science, he said (I think I can recall almost his exact words): 'No incident in my scientific career is more widely known than the part I took in certain psychic researches. Thirty years have passed since I published an account of experiments tending to show that outside our scientific knowledge there exists a force exercised by intelligences differing from the ordinary intelligence common to mortals. This fact in my life is well understood by those who honored me with the invitation to become your president. Perhaps among my audience some may feel curious as to whether I shall speak out or be silent. I elect to speak, although briefly. I have nothing to retract. I adhere to my published statements. Indeed, I might add much thereto.' And when you realize that this includes his astounding experience with 'Katie King,' his words become tremendous in their significance." "What was the 'Katie King' experience?" asked Mrs. Cameron. "I never heard of it." "It is a long and very interesting story, but in substance it is this: While in a condition of contemptuous disbelief as to the alleged phenomena of spiritualism, Sir William chanced to witness a seance wherein a young girl named Florence Cook was the medium. Her doings so puzzled and interested him that he went again and again to see her. Dissatisfied with the conditions under which the wonders took place, he asked Miss Cook to come to his house and sit for him and his friends. This she did. She was a mere girl at the time, about seventeen years of age, and yet she baffled this great chemist and all his assistants. You sometimes hear people say, 'Yes, but he was in his dotage.' He was not. He was in his early prime. He brought to bear all his thirty years' training in exact observation, and all the mechanical and electrical appliances he could devise, without once detecting anything deceitful." "Even in the 'Katie King' episode?" asked Harris.
