consciousness—I must have struck my head on something—I found the microscope in ruins. Upon examination I saw that its larger lens had exploded—flown into fragments scattered around the room. Why I was not killed I do not understand. The ring I picked up from the floor; it was unharmed and unchanged. "Can I make you understand how I felt at this loss? Because of the war in Europe I knew I could never replace my lens—for many years, at any rate. And then, gentlemen, came the most terrible feeling of all; I knew at last that the scientific achievement I had made and lost counted for little with me. It was the girl. I realized then that the only being I ever could care for was living out her life with her world, and, indeed, her whole universe, in an atom of that ring." The Chemist stopped talking and looked from one to the other of the tense faces of his companions. "It's almost too big an idea to grasp," murmured the Doctor. "What caused the explosion?" asked the Very Young Man. "I do not know." The Chemist addressed his reply to the Doctor, as the most understanding of the group. "I can appreciate, though, that through that lens I was magnifying tremendously those peculiar light-radiations that I have described. I believe the molecules of the lens were shattered by them—I had exposed it longer to them that evening than any of the others." The Doctor nodded his comprehension of this theory. Impressed in spite of himself, the Banker took another drink and leaned forward in his chair. "Then you really think that there is a girl now inside the gold of that ring?" he asked. "He didn't say that necessarily," interrupted the Big Business Man. "Yes, he did." "As a matter of fact, I do believe that to be the case," said the Chemist earnestly. "I believe that every particle of matter in our universe contains within it an equally complex and complete a universe, which to its inhabitants seems as large as ours. I think, also that the whole realm of our interplanetary space, our solar system and all the remote stars of the heavens are contained within the atom of some other universe as gigantic to us as we are to the universe in that ring." "Gosh!" said the Very Young Man. "It doesn't make one
