Excerpt from Land Magnetic Observations: 1905-1910The present publication is the first of a series by the Department of Terrestrial Magnetism of the Carnegie Institution of Washington bearing the general title Researches of the Department of Terrestrial Magnetism. Under this head it is proposed to publish the results of the various operations and researches conducted by this Department. While the subject treated will be chie¿y that of the Earth's magnetism, from time to time memoirs will appear on other more or less closely allied subjects, such as atmospheric electricity, for example. The volumes on the work done aboard the magnetic survey vessels, the Galilee, 1905-08, and the Carnegie, 1909 besides giving the results in terrestrial magnetism and atmos pheric electricity, may set forth also the results of observations in atmospheric refraction, etc. In brief, certain volumes or portions of them may be on other subjects than terrestrial magnetism proper.Each volume will have a subtitle setting forth brie¿y its special contents. Thus the present volume, Land Magnetic Observations 1905 contains the results of all magnetic observations made on land by the Department from the beginning of its observational work in February 1905 to the end of December 1910.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
