...substance had leaked into the greenhouse air from illuminating gas. Administered to humans it produces in 40 seconds a complete anesthesia lasting for four hours, making possible prolonged operations. In Chicago, a certain dog, rendered unconcious daily for several years with ethylene, has yet shown no ill effects. An instrument was exhibited which has power to make visible the vital essence of man's life in the form of a thin flame shaking upon a thread. The electricity generated by the heart is carried to a silver quartz thread hanging in a magnetic field. As the heart strikes...
...study of the nerves, muscles, and the heart. The heart in contracting develops electric currents. Every muscle in contracting generates electricity. Of course the amperage is minute, the average magnitude being about one ten-millionth part of an ampere. You can imagine the sensitivity required of any instrument to measure this infinitesimal electric current...
Professor Einthoven's greatest contribution to science has been the invention of an instrument which enables a photographic record to be made of an electric current as minute as that generated by the heart. He accomplished this by the discovery of the wire galvanometer. This consists of a thin wire, stretched in a magnetic field. By virtue of its ability to measure these feeble electric currents of the heart it has proved a tremendous boon to the study of heart disease. So important is it for this purpose that almost every hospital in the country which takes heart patients...
Manhattan Opera House. The Manhattan Opera House, last week, had the distinction of presenting two artists who give place to none in the position they hold in the eyes of the public. First came Anna Pavlowa, for a "farewell season." The instrument of her return was a ballet based on Cervantes' Don Quixote, Mme.
