Experimenta circa Effectum, etc. Expériences sur l'effet du conflict électrique sur l'aiguille animantée.

(Paris, Crochard, 1820). No wrappers. In "Annales". In "Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago" Tome XIV, Cahier 4, Titlepage to vol. 14 + pp. 337-442. (Entire issue offered). Ørsted's paper: pp. 417-25. A few scattered brownspots.

First French translation and the first translation of Oersted's epoch-making announcement in his Latin pamphlet "Extperimenta circa effectum conflictus electrici in acun magneticam. Hafniæ, 1820" (privately printed in a very small number, and only distributed to colleques in Europe). This discovery and confirmation of the connection between 2 forces, electricity and magnetism, must be considered one of the happiest events in the history of science, both with regard to scientific and practical results. - "From the moment that Ørsted's discovery became known it created an enormous sensation. The results communicated were so astounding that they were received with a certain distrust, but they were stated with such accuracy that it could hardly be permitted to entertain any doubts. In the course of a short time the treatise was translated into all the chief languages." (Kirstine Meyer). - Dibner:61 - PMM: 282 - Horblitt: 3 b. - Sparrow: 152.
