"I'll ... be ... damned...." Hilton gulped twice. "Okay, go ahead."

"Your skins will be like ours, energy-absorbers. Your 'blood' will carry charges of energy instead of oxygen. Thus, you may breathe or not, as you please. Unless you wish otherwise, we will continue the breathing function. It would scarcely be worth while to alter the automatic mechanisms that now control it. And you will wish at times to speak. You will still enjoy eating and drinking, although everything ingested will be eliminated, as at present, as waste."

"We'd add uranexite to our food, I suppose. Or drink radioactives, or sleep under cobalt-60 lamps."

"Yes, sir. Your family life will be normal; your sexual urges and satisfactions the same. Fertilization and period of gestation unchanged. Your children will mature at the same ages as they do now."

"How do you—oh, I see. You wouldn't change any molecular linkages or configurations in the genes or chromosomes."

"We could not, sir, even if we wished. Such substitutions can be made only in exact one-for-one replacements. In the near future you will, of course, have to control births quite rigorously."

"We sure would. Let's see ... say we want a stationary population of a hundred million on our planet. Each couple to have two children, a boy and a girl. Born when the parents are about fifty ... um-m-m. The gals can have all the children they want, then, until our population is about a million; then slap on the limit of two kids per couple. Right?"

"Approximately so, sir. And after conversion you alone will be able to operate with the full power of your eight, without tiring. You will also, of course, be able to absorb almost instantaneously all the knowledges and abilities of the old Masters."

Hilton gulped twice before he could speak. "You wouldn't be holding anything else back, would you?"

"Nothing important, sir. Everything else is minor, and probably known to you."
