Unpublished manuscript, 'An explanation of several electrical phenomena' by T [Thomas] Exley Exley attempts to improve on Benjamin Franklin's theories relating to electricity. Exley believes that the phenomena of electricity depend on electrical fluid, which is compressible and elastic; that all bodies acquire some amount of electrical fluid; that electrics are more strongly attracted to electrical fluid than non-electrics; and that if bodies emit electrical fluid they are considered electrified positively whilst if they are receiving the fluid, they are electrified negatively. Minor annotations appear in graphite. Subject: Physics Communicated by the President [Sir Joseph Banks]. Read to the Royal Society on 17 June 1813. [1813]
