Some Early Terrestrial Magnetic Discoveries Pertaining to England

Abstract

IT should be a source of considerable pride to British men of science that so many of the discoveries in terrestrial magnetism have been made in England. And yet, owing to the absence of a complete and carefully written history of the development of this science, probably few could enumerate all the achievements in this subject by Englishmen.

    When Graham discovered, a few years after the publication of Whiston's book, that terrestrial magnetism is subject to a daily variation, Whiston perceived the inutility of his method. See "Memoirs of the Life and Writings of Mr. William Whiston. Written by himself." (London, 1749, vol. 1. p. 297.)

    Whiston even calls these lines also "Magnetick Parallels."
