Die Elektrizität in der Medizin und Biologie : eine zusammenfassende Darstellung für Mediziner, Naturforscher und Techniker
A German technical survey of electricity in medicine and biology, written by physiologist Heinrich Boruttau and published by J. F. Bergmann in Wiesbaden in 1906 for doctors, scientists and engineers. Wood-engraved figures show electrotherapy apparatus in detail: cabinet switchboards of dials and terminals, tripod-mounted lamps and coils, electrode straps, and hands demonstrating instruments, useful as period diagrams of dials, wiring and hardware.
