"You see I have not taken the letter," he said. "If the saw is there, please cut the block in two in the middle. Cut it across the grain." While the sawing was going on, the magician put on his wrap and sat down. He resumed his signet ring, and sat with his head bowed in his hands. When the block had been divided, the ends of the letter, cut in halves, appeared in the midst of the wood. "I think," the stranger said, "that the two halves of the note will slip out of the envelope without difficulty, and Dr. Taunton will then be able to say whether it is the original letter or not." The president with a little trouble pulled out the pieces of paper and fitted them together. He examined them critically, even using a pocket-glass. "If I had not been deceived earlier in the evening, and if I did not know that it is wildly impossible," he said, "I should say that this is my letter." "'I believe because it is impossible,'" quoted the stranger. "You may keep the pieces and decide at your leisure." He rose as he spoke, and once more threw off his robe. The Club waited breathless. He again placed the ring between his feet. "I wish now," he said, "the three globes filled with colored fluid." These were brought to him on a tray, and at his bidding placed close together in a triangle. "This is only another of the innumerable possible variations upon the penetrability of matter, and would come under the head in common nomenclature of that stupidly used term 'fourth dimension.' I said that I am not a juggler, but of course I chose some of the tests because they are picturesque, and so might amuse an audience. See." He laid his hand upon the top of the three globes. Instantly they became one by intersection, the three bases being moved nearer together. Each globe preserved perfectly its shape, and in the divisions now made by the coalescing of the section of one sphere with that of another the liquid was of the hue resulting from a mingling of the colors of the differently tinted fluids. A murmur went around. Several of the members rose to examine the globes. "Put them on the table," the wonder-worker said, "and then everybody may see." "We are not to ask questions of methods," Judge Hobart observed. "Is it proper to inquire whether the experiment involves a contradiction of the old law that two bodies cannot occupy the same space?" "Not at all," was the answer. "Modern science has shown clearly enough that to seem to occupy space is only to fill it as the stars fill the sky. I have only taken advantage of that fact to crowd more matter into a defined area." The members were asked to seat themselves, and when this had been done, the stranger said: "Any number of examples of this power could be given, but these should be enough, unless some one would prefer to improvise a test on the spot."
