While waiting for the water to boil, he arranged his supplies to positions of maximum availability. They were getting low. That baby had taken up quite a bit of useful ingredients; too bad he hadn’t seen his way clear to disassembling it. That meant if there were any argument in favor of allowing the replica of himself to go on living, it was now invalid. He’d have to take it apart in order to have enough for Tina II. (Or Tina prime?)

He leafed through Chapters VI, VII and VIII on the ingredients, completion and disassembling of a man. He’d been through this several times before; but he’d passed more than one law exam on the strength of a last-minute review.

The constant reference to mental instability disturbed him. “The humans constructed with this set will, at the very best, show most of the superstitious tendencies, and neurosis-compulsions of medieval mankind. In the long run they are not normal; take great care not to consider them such.” Well, it wouldn’t make too much difference in Tina’s case—and that was all that was important.

When he had finished adjusting the molds to the correct sizes, he fastened the vitalizer to the bed. Then—very, very slowly and with repeated glances at the manual, he began to duplicate Sam Weber. He learned more of his physical limitations and capabilities in the next two hours than any man had ever known since the day when an inconspicuous primate had investigated the possibilities of ground locomotion upon the nether extremities alone.

Strangely enough, he felt neither awe nor exultation. It was like building a radio receiver for the first time. Child’s play.

Most of the vials and jars were empty when he had finished. The damp molds were stacked inside the box, still in their three-dimensional outline. The manual lay neglected on the floor.

Sam Weber stood near the bed looking down at Sam Weber on the bed.

All that remained was vitalizing. He daren’t wait too long or imperfections might set in and the errors of the baby be repeated. He shook off a nauseating feeling of unreality, made certain that the big disassembleator was within reach and set the Jiffy Vitalizer in motion.

The man on the bed coughed. He stirred. He sat up.

“Wow!” he said. “Pretty good, if I do say so myself!”
