I shut up. It got very still in that hospital room. In the corridor outside feet lisped on tip-toe as a nurse hurried on an errand of mercy. In the far distance a car hooted impatiently as somebody bucked for his place in the emergency receiving room. Dr. Crane stood without moving. His eyes went from Tom to the instrument, then on to Ann, then retraced their course. Tom closed another switch. A white radiation leaped from the cone. It touched Ann's body at the knees. Part of it seemed to dive through the bandages there and flow inward. The rest of it passed upward along the body, penetrating where it touched. It turned the bandages the color of old silver, well polished. "What is that?" Dr. Crane asked. His voice was a taut whisper. "The white light that you see is the visible component of invisible radiations," Tom answered. "It means my generator is not working properly. Otherwise, there would be nothing to see." "Is this the bug you were worrying about?" I asked. "Yes. I didn't have time to clean it up." * * * * * The doctor stepped forward and took Ann's wrist in his fingers. A startled expression appeared on his face. "Her pulse is getting stronger," he said. "She is receiving energy, her whole body is being bathed in it," Tom said. "Seen from one viewpoint, energy is all that exists." His voice suddenly had the dry tones of a professor addressing a class in atomic physics. "Energy in motion at one rate of speed we call light. Energy whose motion has been slowed to a crawl, we call matter. The two are interchangeable. Even the human body, with all of its marvelous glands, its nervous system, and its wonderful brain, falls into the last category. If we could see our bodies as they actually exist, we would be aware of an infinite number of dancing points of light, the infinitesimally minute particles of energy that compose it." He paused. The doctor stood absolutely motionless. "So there is energy--and something else." Tom continued. His voice seemed to come from miles away. "What is this something else?" the doctor asked. "I call it _mind_," Tom answered. "It works with energy, directs it, and moulds it into a thousand different shapes and forms." His voice was soft with awe and reverence. The doctor reached forward to check Ann's pulse. An exclamation of surprise came from his lips. He lifted her arm, then snapped on a light. His surprise grew greater. Snatching a pair of scissors, he cut swiftly through the bandages that swathed her arm. "New flesh!" the doctor gasped. "Where there was only burned meat, now there is new flesh. And n--new skin!" A stutter appeared in the doctor's voice. A glaze came into his eyes. His chest heaved. "Medicine knows nothing like this." His voice was heavy with wonder. "It knows something like this now," Tom said. "Remove the rest of the bandages."
