A major problem was the extreme fragility of the remains, which made any attempt at detailed examination next to impossible. Already the body had undergone some irreparable damage in the course of being transported to Earth and in the removal of the spacesuit; only the body’s being frozen solid during these operations had prevented the situation from being even worse. That was when somebody had thought of Felix Borlan at IDCC and an instrument being developed in England that could display the insides of things. The result had been Caldwell’s visit to Portland.
Inside the first laboratory it was dark. Researchers were using binocular microscopes to study sets of photographic transparencies arranged on several glass-topped tables, illuminated from below. Danchekker selected some plates from a pile and, motioning the others to follow, made his way over to the far wall. He positioned the first three of the plates on an eye-level viewing screen, snapped on the screen light, and stepped back to join the expectant semicircle. The plates were X-ray images showing the front and side views of a skull. Five faces, thrown into sharp relief against the darkness of the room behind, regarded the screen in solemn silence. At last Danchekker moved a pace forward, at the same time half turning toward them.
"I need not, I feel, tell you who this is." His manner was somewhat stiff and formal. "A skull, fully human in every detail-as far as it is possible to ascertain by X rays, anyway." Danchekker traced along the line of the jaw with a ruler he had picked up from one of the tables. "Note the formation of the teeth-on either side we see two incisors, one canine, two premolars, and three molars. This pattern was established quite early in the evolutionary line that leads to our present day anthropoids, including, of course, man. It distinguishes our common line of descent from other offshoots, such as the New World monkeys with a count of two, one, three, three."
"Hardly necessary here," Hunt commented. "There’s nothing apelike or monkeylike about that picture."
"Quite so, Dr. Hunt," Danchekker returned with a nod. "The reduced canines, not interlocking with the upper set, and the particular pattern of the cusps-these are distinctly human characteristics. Note also the flatness of the lower face, the absence of any bony brow ridges… high forehead and sharply angled jaw, well-rounded braincase. These are all features of true man as we know him today, features that derive directly from his earlier ancestors. The significance of these details in this instance is that they demonstrate an example of true man, not something that merely bears a superficial resemblance to him."
The professor took down the plates and momentarily flooded the room with a blaze of light. A muttered profanity from one of the scientists at the tables made him switch off the light hastily. He picked up three more plates, set them up on the screen, and switched on the light to reveal the side view of a torso, an arm, and a foot.
"Again, the trunk shows no departure from the familiar human pattern. Same rib structure… broad chest with well-developed clavicles… normal pelvic arrangement. The foot is perhaps the most specialized item in the human skeleton and is responsible for man’s uniquely powerful stride and somewhat peculiar gait. If you are familiar with human anatomy, you will find that this foot resembles ours in every respect."
"I’ll take your word for it," Hunt conceded, shaking his head. "Nothing remarkable, then."
"The most significant thing, Dr. Hunt, is that nothing is remarkable."
Danchekker switched off the screen and returned the plates to the pile. Caldwell turned to Hunt as they began walking back toward the door.
"This kind of thing doesn’t happen every day," he grunted. "An understandable reason for wanting some… er… irregular action, you would agree?"
Hunt agreed.
A passage, followed by a short flight of stairs and another passage, brought them to a set of double doors bearing the large red sign STERILE AREA. In the anteroom behind, they put on surgical masks, caps, gowns, gloves, and overshoes before passing out through another door at the opposite end.
In the first section they came to, samples of skin and other tissues were being examined. By reintroducing the substances believed to have escaped over the centuries, specimens had been restored to what were hoped to be close approximations to their original conditions. In general, the findings merely confirmed that Charlie was as human chemically as he was structurally. Some unfamiliar enzymes had, however, been discovered. Dynamic computer simulation suggested that these were designed to assist in the breakdown of proteins unlike anything found in the diet of modern man. Danchekker was inclined to dismiss this peculiarity with the rather vague assertion that "Times change," a remark which Hunt appeared to find disturbing.
The next laboratory was devoted to an investigation of the spacesuit and the various other gadgets and implements found on and around the body. The helmet was the first exhibit to be presented for inspection. Its back and crown were made of metal, coated dull black and extending forward to the forehead to leave a transparent visor extending from ear to ear. Danchekker held it up for them to see and pushed his hand up through the opening at the neck. They could see clearly the fingers of his rubber glove through the facepiece.
"Observe," he said, picking up a powerful xenon flash lamp from the bench. He directed the beam through the facepiece, and a circle of the material immediately turned dark. They could see through the area around the circle that the level of illumination inside the helmet had not changed appreciably. He moved the lamp around and the dark circle followed it across the visor.
"Built-in antiglare," Gray observed.
"The visor is fabricated from a self-polarizing crystal," Danchekker informed them. "It responds directly to incident light in a fashion that is linear up to high intensities. The visor is also effective with gamma radiation."
Hunt took the helmet to examine it more closely. The blend of curves that made up the outside contained little of interest, but on turning it over he found that a section of the inner surface of the crown had been removed to reveal a cavity, empty except for some tiny wires and a set of fixing brackets.
"That recess contained a complete miniature communications station," Danchekker supplied, noting his interest. "Those grilles at the sides concealed the speakers, and a microphone is built into the top, just above the forehead." He reached inside and drew down a small retractable binocular periscope from inside the top section of the helmet, which clicked into position immediately in front of where the eyes of the wearer would be. "Built-in video, too," he explained. "Controlled from a panel on the chest. The small hole in the front of the crown contained a camera assembly." Hunt continued to turn the trophy over in his hands, studying it from all angles in absorbed silence. Two weeks ago he had been sitting at his desk in Metadyne doing a routine job. Never in his wildest fantasies had he imagined that he would one day come to be holding in his hands something that might well turn out to be one of the most exciting discoveries of the century, if not in the whole of history. Even his agile mind was having difficulty taking it all in.
"Can we see some of the electronics that were in here?" he asked after a while.
"Not today," Caldwell replied. "The electronics are being studied at another location-that goes for most of what was in the backpack, too. Let’s just say for now that when it came to molecular circuits, these guys knew their business."
"The backpack is a masterpiece of precision engineering in miniature," Danchekker continued, leading them to another part of the laboratory. "The prime power source for all the equipment and heating has been identified, and is nuclear in nature. In addition, there was a water recirculation plant, life-support system, standby power and communications system, and oxygen liquefaction plant-all in that!" He held up the casing of the stripped-down backpack for them to see, then tossed it back on the bench. "Several other devices were also included, but their purpose is still obscure. Behind you, you will see some personal effects."
