Dr. Taussig scoffs at this theory of "genetic weakness" in males. Concerning male abortions he reasons that male fetuses make heavier demands on the mother's body, which she cannot always endure.

Engraving prayers on pinheads may be Art for Art's sake, but making smaller & smaller radio transmitters is a matter of convenience and utility. National Broadcasting Co. last week exhibited a three-inch cubical box with slender, demountable, 10-in. antennae projecting on each side. Like the heavier portable sets which it is intended to replace, this pocket transmitter enables an announcer to roam freely at State fairs, golf tournaments, Roller Derbies and train wrecks, ready to broadcast at any instant.

One ton of that mother ore was reduced to extract a half gram of protoactinium oxide. In a phosgene chlorinating bath this was transposed to a chloride. Using the method evolved by General Electric's famed Irving Langmuir. Dr. von Grosse spread the chloride on a tungsten filament in a vacuum, heated the filament, boiled off the chlorine, obtained his bit of pure protoactinium...

The treated wood is almost as easily tooled as ordinary wood, a little heavier because of the salt content, no different in appearance. It takes varnish well. The Board's testers created conflagration conditions in large chambers fired by gas nozzles, watched through windows. Under conditions that sent untreated walls and floors roaring up in flames, the treated wood did not burn at all. When exposed to intense heat...
