...absorbed in air ten to 25 times more rapidly than had been previously calcu lated, and that absorption is fastest in dry air, a familiar fact to those who know how well sound carries on a foggy day. Since then Dr. Knudsen has not ceased to experiment with the "decay" of sound under various conditions. To the same Journal he has now reported new findings...
...that epoch preceding and overlapping the Roosevelt regime, the eyes of a million Americans would have been straining impatiently for the week's issue of McClure's or Munsey's to soak up eagerly the revelations of Lincoln Steffens on this latest evidence of the decay of the 'System,' as he had named it. Following his hurried, jumpy, journalistic style through its thorough-going exploration of the intricacies and brazen sin of municipal graft. Steffens's audience would read avidly to the last word, throw up its hands in horror at the wickedness of the Big City, make...
...reveries inspired by a sweet pipe-smoke, a pipe-smoke like unto those described in mild, mellow, expensive advertising, the Vagabond has often pondered the decay of magazine editors. Following a train of thought induced by mention of Messers George Horace Lorimer, Bernarr McFadden, and Lincoln Kirstein, he has publicly bewailed the loss of effusions such as those of the youthful Lincoln Steffens. What an opening there is for editors who can today, blud-goon graft and corruption with sweetness and light, as others did of yore, all with the accompaniment of sounding trumpets and falling walls. There...
...chemists to invent uses for zein, a protein left over as a by-product from the corn-refining industry. Arthur Dehon Little, Cambridge industrial chemist, is already experimenting. Zein resembles cellulose and cellulose derivatives in certain ways. It can be mixed with them, as in plastics. It resists water, decay and flames, has advantages as an adhesive, in sizing paper and textiles, and in finishing leather. Chemist Morris Omansky, Boston consultant, reports zein useful as a reinforcing compound for rubber manufacture, arid Dr. Barnard thinks the protein substance might be turned into artificial silk...
...amounts to three million tons yearly. House refuse reaches 1,500,000 tons yearly. Tooth Crystals. X-ray analysis showed J. Thewlis a close analogy between the structure of tooth enamel and the fertilizing mineral apatite. He hopes that further study will show how to prevent tooth decay. Enamel and apatite consist of fibres made up of hexagonal crystals in which precisely the same elements (calcium, oxygen, phosphorus) have precisely the same atomic arrangement. In tooth enamel some of the fibre-axes are inclined 20 degrees to the tooth surface, others 10 degrees. (In dogs' teeth the fibre-axis...
