Nobili - pattern galvanometer composed of a brass base with three leveling screws carrying a glass cylinder. The system of astatic needles is secured at the top of the cylinder. The coil has many windings of thin wire and carries a paper scale. It is rotated by a handle. The base ring carries the name of the maker—T. Gourjon, about whom we have little information—and the words "Galvanometro del Matteucci / 1840 / Corrente Muscolare" ["Matteucci's Galvanometer / 1840 / Muscle Current"]. Carlo Matteucci used this instrument in his studies of currents in wounded muscle fibers. Provenance: Lorraine collections.
