Plate 2.—Photograjih of Spark Discharge on Film. This plate illustrates the effect ofan electric discharge of accidental occurrence just prior to connecting a tube in circuit. Thephotographic plate was on the base of the tube-holder: the patients hands were on the plate,and the wires from a ten-inch coil were sujiported by a high stand with their free ends restingon the table within an inch or two of the plate. The current was accidentally turned on fora few seconds while preparing for the exposure. The negative wire was at the ladys righthand. She felt a shock, bixt there was neither spark nor disruptive discharge seen. No traceof the current could be detected afterward on the plate-envelope. The print shows thatthe spark reaching the film was a small discharge. Beautiful .studies of these tree-fern-liketracings on sensitive films may be made at will by any operator, and it does not require muchof a current to fill the face of an 8 x 10 plate with wonderful markings.
