FARADAY, MICHAEL. - ON ANIMAL ELECTRICITY.

Fünfzehnte reihe von Experimental-Untersuchungen über Elektricität. (Mitgetheilt vom Hrn verfassers aus dem Philos. Transact. 1839). §. 23. Ueber den Charakter und Richtung der elektrischen Kraft des Gymnotus.

(Leipzig, Johann Ambrosius Barth, 1842). No wrappers. In: In "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff", Ergänzungsband (Nach Bd. LI einzuschalten), Stück 3. Pp. 385-528 a. 1 plate. (Entire issue offered). Faraday's paper: pp. 385-405. Clean and fine.

First appearance in German - prepared by Faraday himself for publication in Annalen - of this paper in which Faraday finds, by experimenting with a species of Gymnotus (a group of electric fishes, one was send to him by Humboldt), proves that its electricity is of the same nature as all other kinds of electricity "The skock, in very varied circumstances of position, was procured: the galvanonmets affected, magnets were made, a wire was heated, polar chemical decomposition was effected, and the spark obtained."(Abstract).
