Vesicants are blister-producers. Mustard gas, which is really an oily liquid, was called "the king of battle gases" although it was seldom fatal unless its vapor was inhaled. Masks were of little use, since mustard gas penetrated ordinary clothing and shoes easily, raising huge red welts which sometimes ulcerated and always laid the soldier low for a month or more. When splashed around by shells it contaminates everything it touches for days. It is therefore more valuable for defense than offense, since it is impracticable for attackers to move forward through a mustard-shelled area. Mustard was not introduced...
Outstanding phenomenon of the ascent was the thick and phosphorescent appearance of the balloon ropes at greater elevations. This, Major Stevens explained, was caused by escape of sea level air and water vapor from the fibers of the rigging, at a pressure one-fifth of normal, which formed a foggy cloud around each rope...
...does not melt to a liquid but sublimes directly from the solid state to vapor. When this takes place under confinement, the vapor is formed at high pressure.* Everts and two associates designed a power unit consisting of two small tanks containing 25 Ib. each of dry ice. Sublimed, this delivers a pressure of 1,000 Ib. per sq. in., which is stepped down by control valves to 250 Ib. before being applied to the water hose. Last week
...lamp is a stout, strongly sealed quartz tube less than a quarter-inch in outside diameter, with an inside diameter of .08 to .04 in. It contains neon to start an electric arc, is so full of mercury that when the arc vaporizes the mercury, the pressure rises as high as 300 atmospheres. At the core of the mercury the temperature is 14,000° F., on the inside wall of the tube 1,800°. The lamp is served by a water cooler in which the water must be hurried along in its jacket to prevent the formation...
...chubby sons for whom he keeps a horse and a ponycart. Born in Holland 52 years ago, he came to the U. S. in 1907 to study at Princeton, Stanford, the University of Montana, returned in 1916 to his native land where he worked on the development of sodium vapor lamps in the Philips laboratories and devised a way of sealing chrome steel to glass in X-ray apparatus. Last autumn he again bobbed up at Stanford as a research assistant. "Europe," he said, "iss no blace to bring up fife children." Stanford is financing his present work, expects some...
