...Lubash, who lectures on urology at Flower Hospital Medical School, had a mercury-vapor quartz bulb made a little larger than a match head. This he attached to a copper wire covered by a silk-wound ureteral catheter and attachable to a high frequency apparatus. Last week was too early to show cures in his work, but he had reason to believe that healing light would work as well in a kidney as anywhere else...
...that might well have seemed a sea-rising Aphrodite to an unscientific eye. Writing lately in the scientific magazine Forschungen und Fortschritte, he described a day in Grecian waters when a snowstorm was gathering and the waves were high. As cold air struck the warm water, columns of white vapor rose from the sea. They were held suspended for a moment, then whirled, dissolving away. Professor Walther thought they resembled "feminine figures dancing in filmy draperies...
Mercury Detector. General Electric built a large, efficient generator at Hartford, operated by mercury vapor instead of steam (TIME. July 8, 1929), is building another at Schenectady. The mercury boilers are dangerous because they might leak mercury, poison the workmen. A delicate mercury detector was in order. It is a yellow plaque of selenium sulfide. A few drops of mercury in a furnace through which pass more than 200,000 Ib. of flue gas an hour, said A. J. Nerad, blackens the yellow plaque. The degree of blackening indicates the amount of mercury present. A photo-electric cell measures...
...somewhere. As reported in the New York World, in 1908, a party of detectives detailed to investigate a series of petty robberies in Pittsburgh, saw, early in the morning of July 26, a big black dog sauntering by. "Good morning!" said the dog. "He disappeared in a thin, greenish vapor." Author Fort draws the line at that...
...Through one of two small tubes in the cover of the furnace Engineer Chesnut, wearing dark glasses, could peer, and so good was the insulation that he could put his eye within a few inches of the tube. Keeping the temperature at 3,000°-600° below the vaporization point of graphite-Engineer Chesnut could drop objects through the tube, watch what happened in the hellish interior. Wood was instantly reduced to vapor, burning as a sudden jet of gas. Rocks quickly became vaporized, silicon and magnesium gases shot out into the air burning with a white flame...
