Beebe. From the Galapagos Islands, Explorer William Beebe (TiME, Apr. 27) gave notice that he was returning to Panama for coal, water and ammonia for his ship, the Arc turns. He had discovered a new island and named it after Prof. Henry Fairfield Osborn, President of the American Museum of Natural History. He had caught, among other curious denizens of the deep, a fish with long, jointed, lighted rods issuing from its head...
...Guano, bird dung, valuable because of its nitrate content for fertilizer. When the rains came, the nitrates, escaping as ammonia, left the guano agriculturally impotent...
Then in 1914 Fritz Haber, clever German necromancer, found that nitrogen gas can be captured in another way-by combining it with hydrogen to form ammonia. Instead of electricity, the Haber process makes use of an agent called a "catalyst," which is a substance that by its mere presence causes the union of two other elements. Efficient catalysts, or as Dr. E. E. Slosson calls them, the "good mixers" of chemical society, are expensive. Haber used uranium, platinum or some other rare and finely divided metal. When the nitrogen and hydrogen, after being elaborately purified, mixed in proper proportions, compressed...
...nitrogen research laboratory of the Chemical Warfare Service of the U. S. Army, at Washington, by Dr. Arthur B. Lamb, director of the laboratory, and professor of chemistry at Harvard University. A new catalyst has been found to unite the atoms of nitrogen and hydrogen into the molecule of ammonia. It yields 14% of ammonia, twice the amount given by the Haber process. The nature of the catalyst was not announced, but it has far greater durability, and will make possible explosives and fertilizers both more effective and much cheaper than any now existing...
...contact material, or catalyst, as it is called, which causes the nitrogen in the air to combine with other substances, especially hydrogen, with greater case and efficiency than has hitherto been the case. Where the catalysts used in other processes will produce 7 or 8 percent of ammonia, this new compound will yield 14 percent, and it has been run continuously for six months without deterioration...
