"Can you catch me another fly?" asked the Chemist. The Very Young Man hastened to do so. "The second demonstration, gentlemen," said the Chemist, "is less spectacular, but far more pertinent than the one you have just witnessed." He took the fly by the wings, and prepared another lump of sugar, sprinkling a crushed pill from the other vial upon it.
"When he is small enough I am going to try to put him on the ring, if he will stay still," said the Chemist.
The Doctor pulled the plate containing the ring forward until it was directly under the light, and every one crowded closer to watch; already the fly was almost too small to be held. The Chemist tried to set it on the ring, but could not; so with his other hand he brushed it lightly into the plate, where it lay, a tiny black speck against the gleaming whiteness of the china.
"Watch it carefully, gentlemen," he said, as they bent closer.
"It's gone," said the Big Business Man.
"No, I can still see it," said the Doctor. Then he raised the plate closer to his face. "Now it's gone," he said.
The Chemist sat down in his chair. "It's probably still there, only too small for you to see. In a few minutes, if it took a sufficient amount of the drug, it will be small enough to fall between the molecules of the plate."
"Do you suppose it will find another inhabited universe down there?" asked the Very Young Man.
"Who knows," smiled the Chemist. "Very possibly it will. But the one we are interested in is here," he added, touching the ring.
"Is it your intention to take this stuff yourself to-night?" asked the Big Business Man.
