...hoped that the reader ever will; he writes: "I . . . drank large amounts of various chemicals in solution, some of which have since been used in medicine, though generally in smaller doses than I took. I think I hold the record for the amounts of ammonium, calcium, and strontium chlorides which I have taken." In one essay, "After-effects of Exposure of Men to Carbon Dioxide," he reprints his Lancet article on an experiment he made in connection with the Thetis disaster. This study, as its author points out, has both stylistic and factual interest for the average reader...
Since the first explosion reverberated through the world's laboratories, the fission of thorium, as well as uranium, has been demonstrated. Atom-wranglers at Columbia University have shown that, under various conditions, the fission of uranium yields krypton, strontium, iodine, xenon, tellurium as disintegration products. The flood of reports made it appear that atomic physicists are off on the biggest big-game hunt since the discovery of artificial radioactivity was announced...
...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...
...laboratories in a half-dozen countries, notably England, Italy, the U. S. Italy's Professor Enrico Fermi and his aids have coaxed radiations of beta particles (fast electrons) from phosphorus, iron, silicon, aluminum, chlorine, vanadium, copper, arsenic, silver, tellurium, iodine, chromium, barium, fluorine, sodium, magnesium, titanium, zirconium, zinc, strontium, antimony, selenium, bromine...
...noteworthy that neutrons have been recognized as coming from elements which are the lightest of their groups in the Periodic System. Beryllium is the lightest of the earth alkali group (beryllium, magnesium, calcium, strontium, barium, radium). Boron is lightest of the earth metals (boron, aluminum, scandium, yttrium, lanthanum, actinium). Fluorine is lightest of the halogens (fluorine, chlorine, bromine, iodine and, newly recognized, alabamine...
