[Presentation copy of offprint.] Nouvelles Recherches sur les Propriétés des Courants Électriques Discontinus, et dirigés alternativement en sens contraires, par M. A. de la Rive, Professeur de Physique a l'Academie de Geneve.

80pp., 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. In manuscript at head of title-page: 'hommage de l'auteur'. 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 seven copies on OCLC WorldCat, five in Swiss libraries.
