The cigars were lighted and dinner over before the Doctor broached the subject uppermost in the minds of every member of the party. "A toast, gentlemen," he said, raising his glass. "To the greatest research chemist in the world. May he be successful in his adventure to-night." The Chemist bowed his acknowledgment. "You have not heard me yet," he said smiling. "But we want to," said the Very Young Man impulsively. "And you shall." He settled himself more comfortably in his chair. "Gentlemen, I am going to tell you, first, as simply as possible, just what I have done in the past two years. You must draw your own conclusions from the evidence I give you. "You will remember that I told you last week of my dilemma after the destruction of the microscope. Its loss and the impossibility of replacing it, led me into still bolder plans than merely the visual examination of this minute world. I reasoned, as I have told you, that because of its physical proximity, its similar environment, so to speak, this outer world should be capable of supporting life identical with our own. "By no process of reasoning can I find adequate refutation of this theory. Then, again, I had the evidence of my own eyes to prove that a being I could not tell from one of my own kind was living there. That this girl, other than in size, differs radically from those of our race, I cannot believe. "I saw then but one obstacle standing between me and this other world--the discrepancy of size. The distance separating our world from this other is infinitely great or infinitely small, according to the viewpoint. In my present size it is only a few feet from here to the ring on that plate. But to an inhabitant of that other world, we are as remote as the faintest stars of the heavens, diminished a thousand times." He paused a moment, signing the waiter to leave the room. "This reduction of bodily size, great as it is, involves no deeper principle than does a light contraction of tissue, except that it must be carried further. The problem, then, was to find a chemical, sufficiently unharmful to life, that would so act upon the body cells as to cause a reduction in bulk, without changing their shape. I had to secure a uniform and also a proportionate rate of contraction of each cell, in order not to have the body shape altered. "After a comparatively small amount of research work, I encountered an apparently insurmountable obstacle. As you know, gentlemen, our living human bodies are held together by the power of the central intelligence we call the mind. Every instant during your lifetime your subconscious mind is commanding and directing the individual life of each cell that makes up your body. At death this power is withdrawn; each cell is thrown under its own individual command, and dissolution of the body takes place.
