...insecticides to the rabbits. Some killed the lice, but also killed the lousy rabbits. At last he found a compound (2-pivalyl-I, 3-indandione) which had no apparent effect on the rabbit, but killed all lice that took a single nip. Dose required: 2.5 milligrams (.00006 oz.) per kilogram (2.2 lbs.) of rabbit weight. One-tenth of a milligram fed daily for three weeks was deadly to lice for a month after the dosing stopped. A similar campaign against mosquitoes was not quite so effective. At Kerrville, Tex., an offensive against cattle ticks and lice is still...
...week, learned representatives of 18 countries came to the Pavilion de Breteuil outside Paris, solemnly squeezed into the little vault. There, reposing in a glass case, were the objects these delegates to the first postwar convention of the International Bureau of Weights and Measures had come to see: The Kilogram and The Meter, in person-the official standards of weight and measure for the world's metric system...
...Kilogram is a spool-sized chunk of 90% platinum, 10% iridium, weighing exactly one kilogram (2.2046 Ibs.). The Meter, a rod of the same alloy, is exactly one meter (39.37 in.) long. For nearly 70 years nations have sent their standards to the Pavilion de Breteuil for measuring and checking, but modern science has lessened the importance of The Meter at Paris. Instead of using a meter bar for a check, a scientist in a well-equipped laboratory can now determine the accurate meter in terms of light waves, which give as accurate a measure of distance as direct comparison...
...glimpses of future murders, the visiting newsmen saw an exciting finish to a record-breaking B-29 flight. Just over the finish line, the B-29 plunged down, trailing smoke like a rocket, but somehow landed safely. The record? 2,000 kilometers at 361 m.p.h. with a 2,000 kilogram payload...
...with two oxygen tanks, submarine-type air cleansing devices, tubes for liquid food, the fukuryus could operate in deep water (most effectively at 50 feet), walk under water more than a mile an hour, stay under about ten hours. Each carried at the end of a stick a ten-kilogram explosive charge with contact fuse. A floating chamber behind the charge made it easy to handle. The fukuryus, organized in squads and platoons, were to wait till a vessel passed overhead, then ram the mine into the ship's bottom. They were to be protected from bombardment by underwater...
