Unpublished paper, 'On a possible geological origin of terrestrial magnetism' by Edward Hull

Description

Hull states that the origin and cause of terrestrial magnetism are still subjects of controversy amongst physicists, and this paper is intended to show that the Earth itself contains within its crust a source to which these phenomena may be traced, as hinted at by Gilbert, Biot, and others; though owing to the want of evidence regarding the physical structure of the globe in the time of these observers, they were unable to identify the supposed Earth’s internal magnet.

Annotations in ink throughout. Followed by typed appendix dated 29 May 1889. Includes geological map and diagram.
