The electro-therapeutic guide, or, A thousand questions asked and answered
A question-and-answer manual on electrotherapeutics written by Homer Clark Bennett and issued in 1907 by the National College of Electro-Therapeutics in Lima, Ohio, for practitioners learning to use electrical apparatus on patients. Wood-engraved line cuts show cabinet machines, X-ray lamps on cast-iron stands, electrodes and cords, plus pen-drawn anatomical sections tracing current paths through the body.
