"Just got through to them," Tiger said. "Not too much to go on, but they're really in an uproar. Sounds like they've started some kind of organ-transplant surgery and their native surgeon got cold feet halfway through and wants us to bail him out." Tiger paused. "I think this is going to be your show, Dal. Better check up on Moruan anatomy." It was better than no information, but not much better. Fuzzy huddled on Dal's shoulder as if he could sense his master's excitement. Very few races under contract with Hospital Earth ever attempted their own major surgery. If a Moruan surgeon had walked into a tight spot in the operating room, it could be a real test of skill to get him--and his patient--out of it, even on a relatively simple procedure. But organ-transplantation, with the delicate vascular surgery and micro-surgery that it entailed, was never simple. In incompetent hands, it could turn into a nightmare. Dal took a deep breath and began running the anatomical atlas tapes through the reader, checking the critical points of Moruan anatomy. Oxygen-transfer system, circulatory system, renal filtration system--at first glance, there was little resemblance to any of the "typical" oxygen-breathing mammals Dal had studied in medical school. But then something struck a familiar note, and he remembered studying the peculiar Moruan renal system, in which the creature's chemical waste products were filtered from the bloodstream in a series of tubules passing across the peritoneum, and re-absorbed into the intestine for excretion. Bit by bit other points of the anatomy came clear, and in half an hour of intense study Dal began to see how the inhabitants of Morua VIII were put together. Satisfied for the moment, he then pulled the tapes that described the Moruans' own medical advancement. What were they doing attempting organ-transplantation, anyway? That was the kind of surgery that even experienced Star Surgeons preferred to take aboard the hospital ships, or back to Hospital Earth, where the finest equipment and the most skilled assistants were available. There was a signal buzzer, the two-minute warning before the Koenig drive took over. Dal tossed the tape spools back into the bin for refiling, and went forward to the control room. Just short of two hours later, the _Lancet_ shifted back to normal space drive, and the cold yellow sun of the Moruan system swam into sight in the viewscreen. Far below, the tiny eighth planet glistened like a snowball in the reflection of the sun, with only occasional rents in the cloud blanket revealing the ragged surface below. The doctors watched as the ship went into descending orbit, skimming the outer atmosphere and settling into a landing pattern. Beneath the cloud blanket, the frigid surface of the planet spread out before them. Great snow-covered mountain ranges rose up on either side. A forty-mile gale howled across the landing field, sweeping clouds of powdery snow before it.
