Until 1220 when Alchemist Albertus Magnus discovered arsenic, mankind knew only ten elements-carbon, sulphur, gold, silver, copper, iron, lead, tin, antimony and mercury. In the next 500 years alchemists discovered only bismuth, zinc and phosphorus. Then scientific chemistry began By 1900, before which time perspicacious Dmitri Ivanovich Mendeleyeff figured that there must be 92 elements on earth, no more, no less, chemists had isolated 83. Last discovery of a tangible element, which could be handled and weighed, occurred in 1926 when Professor B. Smith Hopkins of the University of Illinois found Element No. 61 among some rare earths...
From Toronto Dr. William motored the 230 miles to the frontier village where Dr. Allan has practiced for 26 years. In the car were three tanks of oxygen and carbon dioxide to stimulate the babies' breathing in case they turned blue again. The doctor brothers talked until all hours of the morning. "It looks to me," reasoned Dr. Allan, "as though they were uniovular . . . one placenta . . . cords of different length." Dr. William: "I agree...
Last February, as student president, Michelet arranged a memorial service for the nine Dartmouth men killed in their sleep by carbon monoxide (TIME, March 5). But while other students were filing to the chapel, he was on his way to Dick Hall's House infirmary with a heavy cold. The cold became pneumonia. Empyema developed, clogging his lungs. In two weeks students marched once more to Rollins Chapel, for two hours filed past the coffin where Bob Michelet lay beneath the Dartmouth seal...
...Press with it. But in borrowing the Illustrirte Zeitung's feature, the International News editors missed two ingenious points: 1) The pilot did not simply blow the rotors around by sheer lung-power. He breathed normally into the box, in which a marvelous chemical contrivance converted the carbon dioxide of his breath into fuel to run a small motor which turned the rotors! (As everyone should know, carbon dioxide is anything but combustible.) 2) The pilot's name, Koycher (not Kocher), was a freak spelling of Kencher which means "puffer" or "hot air merchant...
Through work on a book on Engineering Materials, with chapters on Testing machines; iron--gray, malleable, wrought, alloy; carbon and alloy steels; heat treating; non-ferrous metals and alloys; copper, tin, nickel, lead, zinc, aluminum, etc., I have come in contact with many products and processes. In spite of the depression, there is marked activity in research work, and as there is activity in this field, then this is the one to train students to enter, instead of in the already overcrowded ones...
