This results ina distortion of the rod which renders it unfit for further use.Mica with a combination of shellac is recommended. Thismechanism is provided with a sliding rod, which may bemoved backwards and forwards, as is desired, thereby in-creasing or decreasing the number of spark gaps in the cir-cuit. Fig. 40 shows one of these interrupters. This isusually known as the Files Interrupter. By the use of thismultiple spark gap, the intensity of the discharge through VACUUM TUBE DISCHARGES. 669 the tube is increased. Fig. 41 shows vacuum tubes withleading-in wires (1) for surface contacts, (2) for aural, and(t,) for nasal applications. These the author has used daily

Many of these were devised by Dr. Snow, and they pre-sent many points of practical value. Especially is this thecase where the part of the tube desired for localization, postnasal, for example, is the seat of the vacuum only, beingsealed off from the length of the tube. These permit of
