Late in the 19th Century a Russian named Iwanowski demonstrated the existence of an infectious something smaller than bacteria by passing a solution from diseased tobacco plants through a Chamberland filter. In time it was found that many animal and human diseases were also due to such viruses: rabies, distemper, foot-and-mouth disease, encephalitis, poliomyelitis, measles, yellow fever, certain tumors, common colds. At Princeton Dr. Stanley grew acres of tobacco plants, infected them with the disease known as tobacco mosaic, ground up their wizened leaves, extracted their juices. This liquid was highly infectious to normal plants. But the deadly...
Harris Hammond earns $20,000 per year, aside from the income from his inheritance. He is president of Dominguez Oil Fields Co. which earned $2,000,000 last year, and of Laughlin Filter Corp., a small New Jersey company which manufactures centrifuges. In 1928 Mr. Hammond and Philadelphia's Anthony Joseph Drexel ("Tony") Diddle Jr. were among the directors of Acoustic Products Co., which later became Sonora Products Corp. of America. When Sonora went bankrupt and Irving Trust Co. became its receiver, that Manhattan bank charged that Sonora's directors had personally used an option owned...
Modern radium extraction is a highly complex process, started with big ovens, reaction vats, filter presses and decanters, working down to delicately controlled processes in vessels hardly larger than thimbles. When the concentration of radium is as high as 1%, trained chemists take over the job, wearing protective gloves and clothing and working intermittently to avoid injury from the potent gamma, beta and alpha rays. The final product is not pure radium but 90 to 94% pure radium bromide...

This party was equipped with a new material for measuring the polarization of the coronal light, a newly invented spinning filter for taking improved pictures of the corona, air conditioning equipment to keep the film cool and dehumidify the developing room, three NBC men to broadcast the performance to the world...
Suddenly last week the Companys technique did not work at all. Late at night telephone communications with France were mysteriously cut. Hours later the story began to filter out of Barcelona that Anarchists had revolted against the Companys Government. Almost instantly jumbled barricades sprang up along the tree-lined Ramblas. The streets echoed with the Carong! Carong! of machine guns, the Hahp! of light artillery. Immediate objective of the Anarchist Black-&-Reds was the Barcelona telephone exchange, a building almost as imposing as the telephone skyscraper of Madrid. This they seized and held for seven hours. Hero of the revolt...
