Hering's sliding bow

(Heringsche Schleife)
Description: No. 203 (see Setup for continuous paper, Fig. 203). Setup for continuous paper/A> does not specifically attribute a source of the use of continuous paper supply; this one specifically cites Ewald Hering, since 1895 the Ordinarius, for physiology in Leipzig. This is an attachment which allows a piece of paper up to 3 m (9 ft) long instead of the .5 m paper typical of a drum. Such setups were used for recordings for early lie detectors.
