'Mayer also undertook to devise a method for finding geographical coordinates independently of astronomical observations. In so doing he arrived at a new theory of the magnet, based, like his lunar theory, on the principles of Newtonian mechanics. This theory represented a convincing demonstration of the validity of the inverse-square law of magnetic attraction and repulsion, and antedated Coulomb's well-known verification of that law by some twenty-five years. Mayer's manuscripts on this theory and its application to the calculation of the variation and dip of a magnetic needle are among those that went virtually unnoticed after his death. . . . E. G. Forbes, ed., The Unpublished Writings of Tobias Mayer, 3 vols. (Göttingen, 1972), contains Mayer's writings on astronomy and geography, his lecture notes on artillery and mechanics, and [in the volume offered here] his theory of the magnet and its application to terrestrial magnetism' (Forbes in D.S.B. IX: 234-5).
