...more ceremonies, no speeches, no cheers. Mechanics turned to promptly, removing the five engines from their egglike gondolas (but leaving the propellers), valving out 60% of the helium into storage tanks. To the chance observer the ship looked about as usual. As everyone knows, a rigid airship's skin is taut whether the gas cells are full or empty...
Speck of Gas. Engineers long ago learned that metals contain absorbed gases. Recently they learned that in lubrication the oil soaks into metal, oozes out when the machine operates (TIME, June 13). How deep into the metal does a gas go, skin-deep or throughout? Dr. Abraham Lincoln Marshall proved?with special heating, evacuating and analyzing devices ?that gas thoroughly permeates metal. From a piece of molybdenum he extracted a speck of gas one-eighth the volume of a common pin, one 100-millionth of an ounce. Dr. Marshall found it a mixture of 43% carbon monoxide, 57% nitrogen...
...death, seared his back and legs. Piped he: "I'm not a dead soldier." Doctors placed him face downward in a sheet steel oven kept at 103° F. to keep his raw back from chilling (TIME, March 28). Where the seared flesh cleared up, doctors grafted skin. Last week indomitable Jack Doty sat on his front porch, virtually healed, after 412 days in the oven...
...Guggenheim Airship Institute was to be dedicated this week. Features: largest vertical wind tunnel in existence, 60 ft. high; a small wind tunnel for testing instruments; meteorological tower; structural testing room. Chief problems to be attacked: nature of the so-called "boundary layer" of air, adjacent to the outer skin of an airship, and its resistant effect upon outriggers, radiators, ventilator hoods and other protrusions; study of surface wind currents which make ground-handling of an airship difficult and hazardous...
...Sweden. During the War we could not get German leeches. I imported some Greek leeches, and they were very good too, but somehow I could not feel at home with them. . . . The leech is an epicure. If he is not hungry you put a little sugar water on the skin to coax him. To make him let go you put salt water. . . . He is also a social barometer. If Prohibition was a success, then there would be less drunks, less black eyes, less demand for leeches. But no, the leech business is good. . . . You drive an old horse into...
