The wooden base, with three leveling screws and lead inset, carries a pedestal for the glass galvanometer housing. The galvanometer comprises a paper scale, a single magnetic needle, and a coil. A brass screw raises and lowers the needle; another rotates the upper part of the galvanometer. This instrument, made by Carlo Dell'Acqua, was invented by the Italian physicist Giovanni Alessandro Maiocchi.
