One should remember that, in the GALVANISM. 29 accidents reported, the person iisualh^ falls on a non-insulatedwire, and so receives a full charge of electricity. As used in an office the current is alwa3s under such com-plete control, if one employ reliable apparatus, that an accidentshould never occur. The current should be the one suppliedfor lighting incandescent lamps. Two curi-ents are used forthis purpose, the direct and the alternating. The direct currentis constant and is the one for physicians to use, as it veryclosely resembles the current obtained from a battery such as the
