It was almost too horrible to be believable. As though it were a bearer of death stripped to the very essentials. A mouth that split the head in two, rows of teeth, serrated and pointed. Leathery, claw-tipped wings, longer claws on the limbs that tore at the metal wall. Terror rose up in Jason as he saw that the claws were tearing gouges in the transparent metal. Wherever the creature's saliva touched the metal clouded and chipped under the assault of the teeth. Logic said these were just scratches on the thick tube. They couldn't matter. But blind, unreasoning fear sent Jason curling away as far as he could. Shrinking inside himself, seeking escape. Only when the flying creature began dissolving did he realize the nature of the room outside. Sprays of steaming liquid came from all sides, raining down until the cylinders were covered. After one last clash of its jaws, the Pyrran animal was washed off and carried away. The liquid drained away through the floor and a second and third shower followed. While the solutions were being pumped away, Jason fought to bring his emotions into line. He was surprised at himself. No matter how frightful the creature had been, he couldn't understand the fear it could generate through the wall of the sealed tube. His reaction was all out of proportion to the cause. Even with the creature destroyed and washed out of sight it took all of his will power to steady his nerves and bring his breathing back to normal. * * * * * Meta walked by outside and he realized the sterilization process was finished. He opened his own tube and climbed wearily out. Meta and the others had gone by this time and only a hawk-faced stranger remained, waiting for him. "I'm Brucco, in charge of the adaptation clinic. Kerk told me who you were. I'm sorry you're here. Now come along, I want some blood samples." "Now I feel right at home," Jason said. "The old Pyrran hospitality." Brucco only grunted and stamped out. Jason followed him down a bare corridor into a sterile lab. The double gravity was tiring, a constant drag on sore muscles. While Brucco ran tests on the blood sample, Jason rested. He had almost dozed off into a painful sleep when Brucco returned with a tray of bottles and hypodermic needles. "Amazing," he announced. "Not an antibody in your serum that would be of any use on this planet. I have a batch of antigens here that will make you sick as a beast for at least a day. Take off your shirt." "Have you done this often?" Jason asked. "I mean juice up an outlander so he can enjoy the pleasures of your world?" Brucco jammed in a needle that felt like it grated on the bone. "Not often at all. Last time was years ago. A half-dozen researchers from some institute, willing to pay well for the chance to study the local life forms. We didn't say no. Always need more galaxy currency."
