Ordinary air is composed of four-fifths nitrogen and one-fifth oxygen and smaller amounts of other gases such as carbon dioxide. The oxygen content of air is the only part valuable to man in breathing. When men work in certain types of caissons, in diving suits or diving bells, they are subject to great air pressure. Under these circumstances, nitrogen goes into the tissues of the body. When the external pressure is released, as by coming out of a caisson or being raised to the surface of the water, the excess nitrogen in human tissues tends to form bubbles...
Muscle Shoals. Use of the largest part of the hydro-electric power developed for the manufacture of fertilizer, containing not less than 40,000 tons a year of pure nitrogen, to be sold at a profit of not over 8%, with farmer control to keep down the cost of distribution. This is coupled with opposition, on account of the delay involved, to the appointment of a commission to solve the Shoals problem...
...Muscle Shoals power, while a nitrogen-fixing industry is developing, will probably be considerably greater than is needed. But, if Muscle Shoals plants were eventually called upon to furnish all the nitrogen compounds necessary for domestic agriculture and industry, they would probably fall short of the demand for lack of power?they certainly would at the present stage of development. On account of the many "ifs," "buts" and uncertainties, whatever disposal is made of the plant must be reasonably flexible in its provisions...
...Scientists have already succeeded in changing nitrogen into hydrogen by the action of alpha particles. This feat was accomplished by Rutherford some time ago. Another investigator has reported a change of tungsten into helium at a very high temperature, but scientists in general consider his results as unconfirmed. The work of Rutherford has been duplicated by several other investigators and his transmutation of nitrogen into hydrogen is accepted as a fact...
...like Death, all-efficient, it is, like Fear, a deterrant to destruction. Sir Max Muspratt spoke. His was a gasconade: "Through Chemistry, man is now on the eve of the most amazing civilizing development in History. Witness phosphates. In days of ignorance, every dead cat was an engine of nitrogen production, every field had its own fertilizer hanging over it, and men of science knew it, but could not use their knowledge. Now we get nitrogen out of the air. This method, evolved in the War, may solve the problem of feeding the world." The report...
