The COMPLEAT Collected SFF Works, page 492
"Very good, Doctor!" But before Conway could ask the Tralthan its name, the entrance lock of the ward swung open and a large, spherical vehicle mounted on caterpillar treads rolled in. The sphere was encircled equatorially by a variety of remote handling and sensory devices, and prominently displayed on the forward upper surface was the insignia of a Diagnostician. Instead, Conway pointed to the vehicle and said, "Can you classify that one?"
This time one of the Kelgians spoke first.
"Only by inference and deduction, Senior Physician," it said as slow, regular waves rippled along its fur from nose to tail. "Plainly the vehicle is a self-powered pressure vessel which, judging by the external bracing evident on the sphere, is designed to protect the ward patients and medical staff as well as the occupant. The walking limbs, if there are any, are concealed by the pressure envelope, and I would say that the number of external handling and sensory devices is so large that it is probable the being has only a small number of natural manipulators and sensors, and operates the external devices as required. The walls of the pressure vessel are of unknown thickness, so that there is no accurate data available to me regarding the size and physical configuration of the occupant."
The Kelgian paused for a moment and sat back on its rearmost legs, looking like a fat, furry question mark. Silvery ripples continued to move slowly along its back and flanks, while the fur of its three fellow DBLFs twitched and tufted and flattened randomly as if there were a strong wind blowing in the observation gallery.
An air of restlessness, of low-key agitation, seemed to pervade the other members of the group. The Tralthans were each raising and lowering their stumpy, elephantine feet in turn. The continuous clicking and scraping sound was the Melfans tapping their crablike legs against the floor, while the teeth of the Orligians showed whitely in their dark, furry faces. Conway hoped they were smiling.
"I am aware of two life-forms which use a pressure vessel of this kind," the Kelgian went on. "They are utterly dissimilar in environmental requirements and physiology, and both would be considered by the more common oxygen- and chlorine-breathing species to be among the exotic categories. One is a frigid-blooded methane-breather who is most comfortable in an environment at a few degrees above absolute zero, and who evolved on the perpetually dark worlds which have been detached from their original solar systems and drift through the interstellar spaces.
"Physically they are quite small," the Kelgian continued, "averaging one-third of the body mass of a being like myself. But during contact with other species, the highly refrigerated life-support and sensory translation systems which they are forced to wear are large and complex and require frequent power recharge ..."
Three of them! Conway thought. He looked around for the Tralthan who had correctly tagged the suited DBLF, and Danalta, the Melfan trainee who had identified the FROB, to observe their reactions to the very knowledgeable Kelgian—but the group was milling about so much that he could not tell who was who. Certainly he had sensed something unusual about this bunch shortly after taking charge of them at the hospital's staff entry port.
"... The other life-form," the Kelgian was saying, "inhabits a heavy-gravity, watery planet which circles very close to its parent sun. It breathes superheated steam and has a quite interesting metabolism about which I am incompletely informed. It, also, is a small life-form, and the large size of its pressure envelope is necessitated by its having to mount heaters to render the occupant comfortable, and surface insulation and refrigerators to keep the vicinity habitable by other life-forms.
"The environment of the Hudlar ward is warm with a high moisture content," the Kelgian continued, "and some measure of the low internal temperature required by a methane-breathing SNLU would be conducted, no matter how efficient the insulation, to the outer fabric of the vehicle, where condensation would be apparent. Since condensation is not present, the probability is high that the vehicle contains the high-temperature life-form, a member of which species is said to be a Diagnostician at the hospital.
"This identification is the result of deduction, guesswork, and a degree of prior knowledge, Senior Physician," the Kelgian ended, "but I would place the entity in physiological classification TLTU."
Conway looked closely at the slow, regular fur movements of the unusually unemotional and well-informed DBLF, and then at the agitated pelts of its Kelgian colleagues. Speaking slowly, because his mind was moving at top speed and little of it was free for speech, he said, "The answer is correct, no matter how you arrived at it."
He was thinking about the DBLF classification, and in particular about their expressive fur. Because of inadequacies in the speech organs, the Kelgian spoken language lacked emotional expression. Instead the beings' highly mobile fur acted, so far as another Kelgian was concerned, as a perfect but uncontrollable mirror to the speaker's emotional state. As a result the concept of lying was totally alien to them, and the idea of being tactful or diplomatic or even polite was utterly unthinkable. A DBLF invariably said exactly what it meant, and felt, because its fur revealed its feelings from moment to moment and to do otherwise would be sheer stupidity.
Conway was also thinking about the Melfan ELNTs and their mechanism of reproduction which made twinning an impossibility, and about the phrasing of the answers volunteered by Danalta and the other two, particularly that of the Kelgian who had implied that the TLTU life-form was not particularly exotic. From the moment they had arrived, he had felt that something was distinctly unusual about the group. He should have trusted his feelings.
He thought back to his first sight of the newcomers and of how they had looked and acted at different times since then, especially their nervousness and the general lack of questioning about the hospital. Was some kind of conspiracy afoot? Without being obtrusive about it, he looked at each of them.
Four Kelgian DBLFs, two Dewatti EGCLs, three Tralthan FGLIs, three Melfan ELNTs, and two Orligian DBDGs—fourteen in all. But Kelgians are never polite or respectful or capable of much control over their fur, Conway thought as he deliberately turned away from them and looked into the ward.
"Who's the joker?" he said.
No one replied, and Conway, still without looking at them, said, "I have no previous knowledge of the life-form concerned, and my identification is based, therefore, on inference, deduction, and behavioral observation ..."
The sarcasm in his voice was probably lost in the translation, and the majority of extraterrestrials were literal-minded to a fault, anyway. He softened his tone as he went on. "I am addressing that entity among you whose species is amoebic in that it can extrude any limbs, sense organs, or protective tegument necessary to the environment or situation in which it finds itself. My guess is that it evolved on a planet with a highly eccentric orbit, and with climatic changes so severe that an incredible degree of physical adaptability was necessary for survival. It became dominant on its world, developed intelligence and a civilization, not by competing in the matter of natural weapons but by refining and perfecting the adaptive capability. When it was faced by natural enemies, the options would be flight, protective mimicry, or the assumption of a shape frightening to the attacker.
"The speed and accuracy of the mimicry displayed here," he continued, "particularly in the almost perfect reproduction of behavior patterns, suggests that the entity may be a receptive empath. With such effective means of self-protection available, I would say that the species is impervious to physical damage other than by physical annihilation or the application of ultrahigh temperatures, so that the concept of curative surgery would be a strange one indeed to members of that race. Virtual physical indestructibility would mean that they did not require mechanisms for self-protection, so they are likely to be advanced in the philosophical sciences but backward in developing their technology.
"I would identify you," Conway said, swinging around to face them, "as physiological classification TOBS."
He walked rapidly toward the three Orligians, for the good reason that there should have been only two of them. Quickly but gently he reached out to their shoulders and slipped a finger between the straps of their harnesses and the underlying fur. On the third attempt he could not do it because the harness and the fur would not separate.
Dryly, Conway said, "Do you have any future plans or ambitions, Doctor Danalta, other than playing practical jokes?"
For a moment the head and shoulders melted and slumped into what could have been the beginnings of a Melfan carapace—the sort of disquieting metamorphosis, Conway thought, which he would have to get used to—before it firmed back to the Orligian shape.
"I am most sincerely sorry, Senior Physician," Danalta said, "if my recent actions have caused you mental distress. The matter of physical shape is normally of complete indifference to me, but I thought that adopting the forms of the people within the hospital would be more convenient for purposes of communication and social intercourse, and I also wished to practice my mimicry as soon and as often as possible before a being who was most likely to spot any inconsistencies. On the ferrycraft I discussed it with the other members of the group, and they agreed to cooperate.
"My chief purpose in seeking a position at the hospital," Danalta went on quickly, "was to have the opportunity of working with so large and varied a group of life-forms. To a mimic of my capabilities—and at this point I should say that they are considered greater than average among my people—this establishment represents a tremendous challenge, even though I fully realize that there will be life-forms which I may not be able to reproduce. Regarding the word 'joker', this does not seem to translate into my language. But if I have given offense in this matter, I apologize without reservation."
"Your apology is accepted," Conway said, thinking of some of the harebrained stunts his own group of trainees had been up to many years ago—activities which had only the most tenuous connection with the practice of medicine. He looked at his watch and added, "If you are interested in meeting a large number of different life-forms, Doctor, you will shortly have your wish. All of you, please follow me."
But the Orligian who was not an Orligian did not move. It said, "As you rightly deduced, Senior Physician, the practice of medicine is completely foreign to our species. My purpose in coming here is selfish, even pleasurable, rather than idealistic. I shall merely be using my abilities to reassure beings who are suffering from physical malfunctions by mimicking them if there are no members of their own race present to give such reassurance. Or to adapt quickly to environments which others would find lethal so that urgent treatment would not be delayed because of time wasted in the donning of protective envelopes. Or to extrude limbs of a specialized shape or function which might be capable of repairing otherwise inaccessible areas where an organic malfunction had occurred. But I am not, and should not be called, a Doctor."
Conway laughed suddenly. He said, "If that is the kind of work you plan to do here, Danalta, we won't call you anything else."
Chapter Two
LIKE A gigantic, cylindrical Christmas tree Sector Twelve General Hospital hung in the interstellar darkness between the rim of the parent Galaxy and the densely populated star systems of the Greater Magellanic Cloud. In its three hundred and eighty-four levels were reproduced the environments of all the intelligent life-forms known to the Galactic Federation, a biological spectrum ranging from the ultrafrigid methane life-forms through the more common oxygen-breathing types up to the weird and wonderful beings who did not breathe, or even eat, but existed by the direct absorption of hard radiation.
Sector General represented a two-fold miracle of engineering and psychology. Its supply and maintenance were handled by the Monitor Corps—the Federation's executive and law-enforcement arm—which also saw to its nonmedical administration. But the traditional friction between military and civilian members of the staff did not occur, and neither were there any serious problems among its ten thousand-odd medical personnel, who were composed of nearly seventy differing life-forms with as many different mannerisms, body odors, and ways of looking at life.
But space was always at a premium in Sector General, and whenever possible the beings who worked together were expected to eat together—though not, of course, of the same food.
The trainees were lucky enough to find two adjoining tables, unlucky in that the furniture and eating utensils were designed for the use of dwarflike Nidian DBDGs. The vast dining hall catered to the warm-blooded, oxygen-breathing members of the staff, and one look around made plain that different species dined or talked shop or simply gossiped together at the same table. Wrong-size furniture was a discomfort which the newcomers would get used to and, in this instance, things could have been much worse.
The Melfan's mandibles were at the right height above the table, and it was no inconvenience for the ELNTs to eat while standing. The Tralthans did everything including sleeping on their six blocky feet. The Kelgians could adapt their caterpillar shapes to any type of furniture, and the Orligians, like Conway himself, could sit without too much discomfort on the armrests of the chairs. The tiny Dewatti had no problems at all, and the polymorphic Danalta had taken the shape of a Dewatti.
"The food-ordering and delivery system is standard," Conway said, looking from one table to the other, "and the same as that used on the ships which brought you here. If you punch in your physiological classification, the menu will be displayed in your own written language. Except for Danalta. There are no special dietary requirements for the TOBS life-form, I suspect, but no doubt you have preferences? Danalta! ..."
"Your pardon, Senior Physician," the TOBS said. While it watched the dining hall entrance, its body was twisted into a shape impossible for a Dewatti. "My attention was taken by the incredible assortment of beings who come and go here."
"What would you like to eat?" Conway asked patiently.
The TOBS spoke without turning its Dewatti head. "Virtually anything which is not radioactive or chemically corrosive, Senior Physician. Were nothing else available I could, in a short time, metabolize the material of this dining furniture. But I eat infrequently and will not need to do so again for several of your days."
"Fine." Conway tapped for a steak before going on. "And Danalta, while it is very pleasant, and rare in this establishment, to be addressed properly and with respect, it can be cumbersome. So it is customary to address interns, Junior and Senior Physicians, and even Diagnosticians as Doctor. Have you seen a physiological type which you cannot reproduce?"
Conway was beginning to feel irritated at the way Danalta kept looking at the entrance while he was speaking, and wondered if it was a trait peculiar to the species and the impoliteness unintentional. Then he nearly choked when he saw that the TOBS had extruded a small eye from the back of its head to watch him.
"I have certain limitations, Doctor," it replied. "Shape changing is relatively easy, but I cannot discard physical mass. This ..."—it indicated itself—"is a small but very heavy Dewatti. And the entity who has just entered would be very difficult to reproduce."
Conway followed the direction of its other eyes, then stood up suddenly and waved.
"Prilicla!"
The little being who had just entered the dining hall was a Cinrusskin GLNO—a six-legged, exoskeletal, multiwinged, incredibly fragile insect. The gravity of its home world was one-twelfth Earth normal, and only double sets of gravity nullifiers kept it from being smashed flat against the floor, enabled it to fly or, when the unthinking movements of its more massive colleagues threatened life and ultrafragile limb, to scamper safely along the walls or ceiling. It was impossible for offworlders to tell Cinrusskins apart; even Cinrusskins could only differentiate between members of the species by the identification of individual emotional radiation. But there was only one GLNO empath on the hospital staff; this one had to be Senior Physician Prilicla.
The occupants of both tables were watching the little empath as it flew slowly toward them on its wide, iridescent, almost transparent wings. As it came to a gentle halt above them, Conway noticed a faint, erratic trembling in the six pipestem legs and its hover showed definite signs of instability.
Something was distressing the little Cinrusskin, but Conway did not say anything, because he knew that his own concern was already obvious to the empath. He wondered suddenly if the sight of the GLNO had triggered some deep-seated phobia in one of the new arrivals and it was radiating fear or revulsion with sufficient intensity to affect Prilicla's coordination.
He would have to put a stop to that.
"This is Senior Physician Prilicla," he said quickly, as if he was making a simple introduction. "It is a native of Cinruss, a GLNO, and possesses a highly developed empathic faculty which, among other uses, is invaluable in detecting and monitoring the condition of deeply unconscious patients. The faculty also makes it highly sensitive to the emotional radiation of colleagues such as ourselves who are conscious. In Prilicla's presence we must guard against sudden and violent mental reactions, even involuntary reactions such as instinctive fear or dislike at meeting a life-form which, on another species' home planet, is a predator or the object of a childhood phobia. These feelings and reactions must be controlled and negated to the best of your abilities because they will be experienced with greater intensity by the empath. When you become better acquainted with Prilicla, you will find that it is impossible to have unpleasant feelings toward it.
