“But I thought there were only ninety-two elements in the universe and we’d discovered them all.”

“So we have. But don’t forget this. We are still trying to split the atom, which nature has done many times and will doubtless do many times again. It is merely a matter of altering the valence of the atoms in an old element; whereupon it shifts its position in the periodic scale and becomes a new element. Nature accomplishes this alchemy by means of great heat, which is certainly to be found in a meteor.”

“Particularly when it hits the earth’s atmosphere!”

“Yes. And now then, I’d like to have you examine more closely this pair I have here.”

Jim lifted one and noted its peculiar smoothness, its remarkable weight for its size; he noted, too, that it was veined with concentric markings, like a series of arabesques or fleurs-de-lis.

The professor lifted the other, calling attention to the fact that the size and marking of both were identical, as hitherto reported.

“Also, you’ll observe that they are slightly warm. In fact, they are appreciably warmer than when they were first brought in. Curious behavior, this, for new-laid cometary eggs! More like seeds germinating than meteorites cooling, wouldn’t you say?”

“But good Lord!” Jim was somewhat taken aback to hear this celebrated scientist apparently commit himself to that wild view. “You don’t really think they’re seeds, do you?”

“Why not?”

“But surely no seeds could survive the temperature they hit getting here.”
