Telltale Band. Most important was proof that organic (carbon-hydrogen) compounds probably exist on Mars. Dr. William Sinton of the Smithsonian Institution started with the fact that compounds containing carbon, when joined to hydrogen, absorb infra-red radiation with a wave length of 3.46 microns. His first step was to look for this absorption band in infra-red light reflected from dry leaves, lichens and mosses, which are made almost entirely of carbon-hydrogen compounds. It showed up strongly...
Then Dr. Sinton hitched a supersensitive infra-red detector to Harvard's 61-in. telescope and looked for the same absorption band in sunlight reflected from Mars. Many observations were necessary because of the feebleness of Martian light, but at last the band appeared. Apparently, something on Mars absorbs infra-red in the same way that earthside vegetation does. Dr. Sinton thinks his observation is strong evidence that Mars has living organisms whose bodies are made of compounds containing carbon and hydrogen...
...part of the sun's radiation penetrates to the shiny aluminum and is mostly reflected back into space. The temperature of the aluminum rises slowly, both because it is a poor absorber and because the silicon monoxide layer in contact with it is a comparatively good radiator of infra-red (heat) rays. By experimenting with different thicknesses of silicon monoxide, the Navy's scientists think they can keep the temperature of the skin below 140° F. The sensitive instruments inside will be comfortable at about 120° F. When the satellite passes into the shadow...
...three companies peddling arthritis and rheumatism palliatives: Buffalo's Mentholatum Co., maker of Mentholatum Rub; Manhattan's Whitehall Pharmacal Co., maker of Infra-Rub and Heet; and Jersey City's Omega Chemical Co., distributor of Omega...
Typical spot commercial (for Mentholatum Rub): "These are arthritic hands. They belong to a retired foreman and 20-year sufferer of arthritic pain and misery. You're looking at them now as they experience a totally new kind of pain relief . . ." An Infra-Rub plug: "Brings comforting warmth from deep within . . . 146 doctors report success based on hundreds of cases." For Omega Oil: "It contains an active ingredient that actually penetrates the skin...
