Priestley did not know what he had made when he heated red oxide of mercury with a burning glass and collected the atmosphere caused by the process. He labored under an old notion that combustible substances had a constituent, "phlogiston," which departed from them when they burned (as soot, for example). Thus, when he found that a candle burned more brightly, and mice thrived, in the atmosphere created with his container of heated mercuric oxide, he thought this atmosphere was "dephlogisticated air." Fortunately, while touring Europe with a patron, he met the Frenchman, Lavoisier, and told him of his experiment...
...that the Aluminum Co. controlled the great U. S. deposits of bauxite, the commercial ore from which aluminum is extracted. These deposits are in Alabama, Tennessee, Georgia, Arkansas.

Manufacturer Haskell located other deposits, until then unknown to the Aluminum...
Smoke Photography. Aerial photographers at McCook Field, Ohio, gave full credit to the Eastman Kodak Co. for new "K-panchromatic" plates by which flying observers can photograph the earth through smoke screens and light fog. The plates are treated with a secret cyanide, "krypto-cyanide," sensitive to infra-red rays which, though invisible to the eye, penetrate smoke and water vapor to record an image in the camera. The significance: protection for wartime mapmakers...

She soon went back; Mrs. Mallory smashed to victory...

S. chemists have since corrobated the green effect in radiumized diamonds. Dr. Field is first to announce a blue-white effect. Other experiments with radium have turned pink synthetic sapphires red or orange; a white sapphire yellow; blue sapphires gray or brownish green; a colorless topaz to amber's color...
