“Thank you.”
Conway’s words were received by the being who was manning the reception board, whose translator pack relayed them to the computer which occupied three whole levels at the nerve-center of the hospital, which in turn returned them stripped of all emotional overtones to the scaly, furry, or feathery receptionist in the form of hoots, cheeps, growls, or whatever other odd noises the being used as its spoken language.
To Edwards, Conway said, “Unless you are attached to a multienvironment hospital you normally meet e-ts one species at a time and refer to them by their planet of origin. But here, where rapid and accurate knowledge of incoming patients is vital, because all too often they are in no condition to furnish this information themselves, we have evolved the four-letter classification system. Very briefly, it works like this.
“The first letter denotes the level of physical evolution,” he continued. “The second indicates the type and distribution of limbs and sense organs and the other two the combination of metabolism and gravity-pressure requirements, which in turn gives an indication of the physical mass and form of tegument possessed by a being. Usually we have to remind some of our e-t students at this point that the initial letter of their classification should not be allowed to give them feelings of inferiority, and that the level of physical evolution has no relation to the level of intelligence.”
Species with the prefix A, B and C, he went onto explain, were water breathers. On most worlds life had begun in the seas and these beings had developed high intelligence without having to leave it. D through F were warm-blooded oxygen breathers, into which group fell most of the intelligent races in the galaxy, and the G to K types were also oxygen breathing but insectile. The Ls and Ms were light-gravity, winged beings.
Chlorine-breathing life-forms were contained in the 0 and P groups, and after that came the more exotic, the more highly evolved physically and the downright weird types. Radiation eaters, frigid-blooded or crystalline beings and entities capable of modifying their physical structure at will. Those possessing extrasensory powers sufficiently well-developed to make walking or manipulatory appendages unnecessary were given the prefix V regardless of size or shape.
“There are anomalies in the system,” Conway went on, “but those can be blamed on a lack of imagination by its originators-the AACP life-form, for instance, which has a vegetable metabolism. Normally the prefix A denotes a water breather, there being nothing lower in the system than the piscatorial life-forms, but the AACPs are intelligent vegetables and plants came before fish-”
“Sorry, Doctor,” said the pilot. “We’ll be docking in five minutes and you did say that you wanted to prepare the visitors for transfer.”
Conway nodded and Edwards said, “I’ll lend a hand, Doctor.”
The scout ship entered the enormous cubic cavern which was Lock Twenty-three while they were donning the lightweight suits used for environments where the liquid or gas was lethal but at reasonably normal pressures. They felt the grapples draw them into the adjustable cradle and staggered slightly as the artificial gravity grids were switched on. The Lock’s outer seal clanged shut and there was the sound of waterfalls pouring down metal cliffs.
Conway had just finished securing his helmet when its receiver said, “Harrison here, Doctor. The reception team leader says that it will take some time to completely fill the lock with water as well as making it necessary to carry out the full anti contamination procedure at the other five internal entrances. It is a big lock, pressure of water on the other seals will be severe
if-”
“Filling won’t be necessary,” said Conway. “The Drambon CLCH will be all right so long as the water reaches the top edge of the freight hatch.”
“The man says bless you.”
They let themselves into the scout ship’s hold, carefully avoiding the self-powered life support machinery which kept the first Drambon rotating like an organic prayer wheel as they removed the retaining straps from the freight lashing points.
“We’ve arrived, Surreshun,” said Conway. “In a few minutes you’ll be able to say good-bye to that contraption for a few days. How is our friend?”
