He was gone when they came to wake him from his sleep period. His bunk had been slept in, but he wasn't in it. In fact, he wasn't anywhere on the ship.

"But he couldn't just vanish!" the Black Doctor burst out when they told him the news. "Maybe he's hiding somewhere. Maybe this business was working on his mind."

The hlorg had stopped eating. Huge and round and wet and ugly, it squatted in the after-hold, quivering gently, without any other sign of life.

Surfeited. Like a fat man after a turkey dinner.

Jenkins reviewed progress with the others. No stone had been left unturned. They had sliced the hlorg, and squeezed it. They had boiled it and frozen it. They had dropped chunks of it in acid vats and covered other chunks with desiccants and alkalis. Nothing seemed to bother it.

A cold environment slowed down its activity, true, but it also stimulated the process of fission. Warmed up again, the portions sucked back together again and resumed eating.

Heat was a little more effective, but not much. It stunned the creature for a brief period, but it would not burn. It hissed frightfully and gave off an overpowering stench, and curled up at the edges, but as soon as the heat was turned off it began to recover.
