Shopkeepers were worried but courageous. A typical window sign in a St. Paneras grocery: "Called up, wife carries on." One West End druggist put a sign in his window: "Bismuth as usual during altercations...
This force is comparable to those which occur nearly ninety-five miles within the earth. Under such a pressure new forms of bismuth and helium have been developed...
...been breathing with lungs for a million years. Men have been studying the lungs's physiology for nearly 5.000 years. But not until Radiologist Alfred Ernest Barclay* took to blowing bismuth and powdered glass down the windpipes of cats was one of the lungs's important protective devices thoroughly studied. Last week his findings were published in the American Journal of Roentgenology...
...walls of most of the throat, of the windpipe and its branches (bronchi and bronchioles) are covered with fine, threadlike filaments called cilia, which continually move, waving their tips with an upward motion. When bismuth powders or pulverized lead glass were blown deep into the lungs of anesthetized cats, Dr. Barclay and his associates found that the dust in dry form remained in the windpipe and its branches, never penetrating into the little sacs (alveoli) which absorb oxygen from the air and eliminate carbon dioxide from the blood. They could see by X-ray the foreign particles moving from...
...tiny high pressure laboratory, Professor Bridgman has produced forms of bismuth, gallium, calcium, strontium, barium, and cesium which have never been seen before. As in the case of red and yellow forms of sulfur that are seen under ordinary pressures, he has made forms of these elements that differ from their usual forms in appearance and in physical properties...
