(Forgotten Books, July 13, 2017)
Excerpt from A Treatise on Magnetism: General and TerrestrialThe account which the author has given of the principal results obtained in recent years in connexion with the variations of terrestrial magnetism, will, he trusts, serve the same purpose; while, at the same time, it presents the general scientific reader with a condensed summary of the leading facts of the science. As it would have been impossible to give in a mode rate compass the numerical representation of the laws deduced at all the co-operating observatories, the course pursued has been to present the results oh tained at a single station, at which all the general features of the phenomena belonging to the middle northern latitudes were fully developed, and to sup plement the information by the results of observation at places widely removed from the former in geograp phical position, as well as in their relation to the sun's daily and yearly courses. The single station selected for this purpose is Dublin, partly because it fulfils the condition above described, and partly, also, because the reductions have been there made according to me thods' which appear to the author himself to be the most suitable.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
