[Offprint.] Des Mouvements Vibratoires que déterminent dans les Corps, et essentiellement dans le fer, la transmission des courants électriques et leur action extérieure. Par Mr. le Professeur de la Rive.

35pp., 8vo. Stitched and unbound. All but the first few leaves unopened. In fair condition, on aged and worn paper, with traces of the original blue wraps adhering at spine. At the time of his death de la Rive's work was deemed by one obituarist ' indispensable for the scientific student of electricity', and the phrase was repeated in the eleventh edition of the Encyclopaedia Britannica. Scarce: no copy in the Bibliothèque Nationale, and of the nine copies on OCLC WorldCat, eight in Swiss libraries.
