Magneto-electric generator operating in an altogether similar manner to the machine invented by Edward Marmaduke Clarke (inv. 515). A horseshoe permanent magnet on gilded feet carries two ivory bobbins with windings of silk-covered wire. The bobbins were rotated near the magnet poles by means of a gilded pulley wheel. This compact and easily transportable device was used for electrotherapy, and the current was applied to the patient by means of two electrodes.
