Unpublished paper, 'On the unsymmetrical distribution of terrestrial magnetism' by Henry Wilde Wilde continues his researches into terrestrial magnetism (see AP/66/29). He writes that 'it was surmised that the asymmetry might be due to the diamagnetism of the waters of the globe, and of the compounds of the alkaline metals which they hold in solution.' He aims to test the correctness of this theory. Annotations in pencil. Subject: Physics / Geology / Magnetism Received 20 November 1890. Read 22 January 1891. 19 November 1890
