...Ambassador Sir Nevile Henderson flew to Berchtesgaden with a note from Mr. Chamberlain saying: "War between our two peoples would be the greatest calamity that could occur. . . . I cannot see that there is anything in the questions arising between Germany and Poland which could not . . . be resolved without the use of force...
Naphthalene acetic acid and naphthalene acetamide are two of the "growth substances" or hormone-like chemicals, which growers now use to stimulate root-sprouting, accelerate pollen production, etc. etc. Dr. Frank Easter Gardner and his co-workers at the U. S. Bureau of Plant Industry station in Beltsville, Md. decided to try these two naphthalene compounds as a spray to keep ripening apples from dropping. They sprayed ten varieties of apple trees just before crop maturity, were signally successful in preventing premature falls. In Science last week they reported that in tests on one troublesome variety ("Williams Early Red") only...
Thirty-six gases were used in World War I-every one of which was a known chemical compound or element and many (like chlorine and phosgene) were useful in peace before the War. Their use in battle was not a scientific but a manufacturing problem. With their powerfully developed chemical industry, the Germans had a considerable edge on the Allies, and Allied gas warfare was largely a series of belated retaliations...
...mustard, phosgene, diphosgene, chlorpicrin, diphenylchlorarsine) proved highly efficient.* Two gases which showed deadly promise-Lewisite, an arsenical blister-producer, and Adamsite, a respiratory irritant-were developed by the Allies during the War, but the peace was signed before they got into action. Adolf Hitler promised last week not to use poison gas, but if gas rolls into the European arena notwithstanding, Lewisite and Adamsite are almost certain to get a thorough trial. Otherwise, military experts believe, the armies will rely on the half-dozen gases which proved efficient in World War I. Though nobody can deny it with certainty...
...military metallurgy, beryllium is rated a new wonder metal. The element beryllium was discovered by a Frenchman in 1797, but during World War I and for years afterward there was no known use for it; in 1923 its price was $5,000 per pound. But beryllium ores are scattered widely over the world and last week the price of the metal was down to about $11. Not quite twice as heavy as water, beryllium is one of the lightest of all metals. It is a third lighter than aluminum. Chemically wedded to copper or nickel, it makes an extremely hard...
