Graybill's electrode for cataphoresis

An uncommon device for the topical application of an electrified medicament. The liquid preparation is contained in the glass cylinder and released by opening a valve between the reservoir and the sponge pad. A coil of wire runs almost the entire length of the cylinder and is affixed at the top to a binding post which, in turn, connects to a wire from the electrical source. The coiled wire provides a large contact surface with the liquid. The liquid completes the circuit to the patient's skin. A conventional galvanic electrode would be used to return the current to the source. The instrument is marked "Lentz & Sons" and "Pat Oct 8, 1901, Geo Graybill, York, Pa". The sponge holder is secured with clips, making it easily removable when changing medication. The head is mounted on a ball joint to allow the pad to pivot, apparently for more comfortable use. The leather lined box is in good condition, but lacking the Lentz sticker inside the lid.

This device could also be used for local anesthesia, using morphine or cocaine. Richardson first used electricity to administer morphine for local anesthesia in 1859.
