AEPINUS, Franz Maria Ulrich Theodor (1724-1802). Tentamen theoriae electricitatis et magnetismi. St. Petersburg: typis Academiae Scientiarum [1759].
4° (265 x 196mm). 7 folding engraved plates. (Stitching of first gathering a little weakened at foot, occasional light browning.) Contemporary calf-backed boards (lightly rubbed).
FIRST EDITION of ‘one of the most original and important books in the history of electricity’ (DSB). Aepinus adopts and modifies Franklin’s one-fluid theory of electricity, discusses his discovery of electric influence, and the electric properties of heated tourmaline. He was also the first to maintain that there is no sharp division between conductors and non-conductors of electricity, the difference between them being their lesser or greater resistance to the passage of electricity. Wheeler 395.
