The orginal edition. "This bibliography fully describes the library of some 6000 books and pamphlets on electricity, magnetism, and telegraphy printed before 1886. Collected by Latimer Clark, the library was purchased in 1901 by Schuyler Skaats Wheeler, an American inventor and manufacturer, for presentation to the American Institute of Electrical Engineers. A great many of the books in this library, particularly the final two thousand items, concern telegraphy".

First appearance of a milestone paper in the history of electricity as Aepinus here found that a heated tourmaline attracted and repelled light bodies. He decided, that the effect was electrical and that its ends was carrying charges of opposite sign, much as soft iron is magnetized by a lodestone. This paper is a forerunner of his ""Tentamen Theoriae electricitatis et magnetismi"", - published 1759, and one of the most original and important books in the history of electricity. It is the first reasoned, fruitful exposition of electrical phenomena based on action-at-a-distance.""Aepinus’ first reseraches on the thermoelectric properties of this stone (Tourmalin) which was then of extreme rarity, were fundamental. He recognized the electrical nature of the attractive power of a warmed tourmaline and attempted not altogether successfully, to reduce its apparent capriciousness to rule. He was particularly struck by the formal similarity between the tourmaline and the magnet in regard to polarity which inspired him to reconsider the possibility, then occasionally discussed, that electricity and magnetism were basically analogous. This thought became the This thought became the theme for his masterwork, Tentamen theoriae electricitatis et magnetismi (1759).""(DSB).""Aepinus is known in the history of electricity for his attempt to develop the one fluid theory of Franklin. His theory was for a while generally adopted, but was gradually displaced by the two fluid theory, in consequence chiefly of the necessity of ascribing to uncharged matter repulsions of the same force as those which were ascribed to electrical charges. His theory exhibits interesting similarities to the present theory of the constitution of matter""(Magie ""A Source Book in Physics"", pp.406-8).Ronalds p. 4.
