...vapor but water in fine particles. Having produced artificial fog in his laboratory. Researcher Houghton measured the size of the droplets by trapping them on greased slides, found them to vary from .0008 to .0004 of an inch. He sought a chemical means of making them combine into drops big enough to fall of their own weight. Having found it and used it last week at Round Hill, he now thinks ocean liners might use it to sweep their paths clear, airports might use it to help incoming planes land...
...mixture of the cold air from the north and the southern warm air. Following the path usually taken by such pressure areas, the cyclone passed over Georgia resulting in much damage of property and loss of life. Travelling up the coast, the gale collected moisture from the ocean. This vapor rose into the upper strata of the air and congealed there, at a temperature of 30 or 50 degrees below zero...
Germany's Dr. H. O. Kneser has suggested that a large part of the absorption in air is due to collisions between oxygen molecules and water vapor molecules. Dr. Knudsen's experiments with air and its two major components, oxygen and nitrogen, weigh heavily in favor of this suggestion. There was no appreciable difference in the decay rates in moist nitrogen and dry nitrogen. But the decay rate in moist air was only one-fifth the rate in moist oxygen, and oxygen is one-fifth...
...lips are red with a dye from the "Kermes berry." Kermes is not a berry at all but a bug - a reddish, wingless female insect, relative to the cochineal of Mexico, that lays its eggs on oak leaves throughout southern Europe. The insects are killed in a vapor of hot vinegar, dried, and ground for pigment. It takes 10 to 12 lb. of kermes to produce as red a color as one pound of cochineal. The Louvre lady's lips are of cochineal, unknown in Europe before Cortes brought it back in 1523, unknown in Italy for 20 years...
...with lamp bulbs. In Europe that function is performed chiefly by potent Philips Glow-lampworks of Holland, which also boasts one of the finest physical research laboratories east of the Atlantic. Last week it appeared that all three companies were working independently on the same thing -a new sodium vapor bulb to be used primarily for street lighting. In Manhattan, 100-odd members, of the New York Electrical Society sat like jaundiced mummies in an auditorium suffused with the yellow sodium light while their president described the particular bulb of the Dutch company. In Andover, N. J., Westinghouse was demonstrating...
