"There, I think, is what you wish to see first," he announced, as he finally steadied the controls, and Brandon cut in upon the shunting screen the infra-red transformer. This device, developed long before to render possible the use of Terrestrial eyes in the opaque atmosphere of Venus, stepped up the fog-piercing long waves into the frequencies of light capable of affecting the earthly retina.
For this purpose the radiant source used was a strip of platinum covered with fluorine or powdered quartz, which emits numerous radiations close to two bands of linear absorption in the absorption spectra of fluorine and quartz, one of which is situated in the infra-red.
The infra-red ray which has been developed by LeCroix from the experiments of the Italian scientist Ulivi causes, when concentrated by an apparatus perfected by LeCroix, an instantaneous combustion of nonreflecting surfaces. It is particularly deadly in its effect on the brain centers. It can be diverted, it is said however, by a shield composed of platinum backed by asbestos.
"I will now show you, my dear young lady," almost hissed the Clutching Hand at length, "as pretty a game of hide and seek as you have ever seen." As he said it, another trap door near the infra-red ray machine was opened and a beam of light burst through. I knew it was not that which we had to fear, but the invisible rays that accompanied it, the rays that had affected the bolometer.
Then, his face white and wet, he dropped his hand. "No use, Mart I can't do it. It pulls my cork. I know darn well you can't either I'll yell for help." "Have you got it on the infra-red?" asked Dunark calmly, as he shot up into the projector in reply to Seaton's call. "I want to see this, all of it."
Stanton approached the turn and took off the infra-red goggles. Enough light spilled over from the Nipe's lair to illuminate the tunnel. He put the goggles on the trackway. He wouldn't need them again. He went on around the curve, slowly and quietly. He didn't want to fight down here in the tracks, and he didn't want to be caught just yet.
If we live, I'll have to get back in time to telephone the story to McQuarrie for the first edition." I followed Jim out of the laboratory and to a large open space behind the main building where the infra-red generators with which he had pierced the hole through the heaviside layer had been located. The reflectors were still in place, but the bank of generators had been removed.
Day or night makes no difference we'll have to use infra-red anyway, because of the fog, and that's almost as good at night as in the daytime. There is no such thing as absolute darkness upon any planet, anyway, and we've got power enough to make anything visible that happened there, night or day.
At three hundred miles an hour the Sandra had nicked the upper plates of the dome and streaked on, unharmed! It was not necessary now to use infra-red glasses to see the asteroid. It was there in the visi-screen for naked eyes, but for seconds not one of the men in the ship's control-cabin thought to look. The awful acceleration and shock had dazed them.
Thus it came about that the head of the column of police had scarcely passed a certain door, when in the room behind it there began to assemble the half-hundred spacehounds of the hexans. When the vanguard had approached that room, Crowninshield had inspected it thoroughly with his infra-red beams. He had found it punctured and airless, devoid of life or of lethal devices, and had passed on.
