GAUSS, C.F. - INTRODUCING ABSOLUTE UNITS IN MAGNETISM AND ELECTRICITY.

Mesure absolute de l'Intensité du Magnetisme terrestre.

Paris, Crochard, 1834. Without wrappers. In: "Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago.", Tome 57, 2e Series. Cahier 1. 112 pp. (entire issue offered with titlepage to vol. 57). Gauss' paper: p. 5-69. Some brownspots.

First French edition of Gauss' "Intensitas vis magneticae terrestris ad mensuram absolutam revocata" (1833), Gauss' first work on magnwetism, in which appeared the first systematic use of of absolute units, distance, mass, time to measure nonmechanical quantity (magnetism and electricity). - "It contains the first measurement of magnetic and electric quantities" (Magie, A Source Book in Physics, p. 519).
