Sparksmay be obtained from the resonator by using a ball electrode andlengthening the gap between the spark rods e and / of the reso-nator. The sparks are seldom used from the resonator on accountof the danger of Hollow glass electrodes, exhausted to a low vacuum, are useduniversally for the administration of high-frequency currentsto the surface and various cavities of the body. These elec-trodes are of two general varieties—plain and insulated. The plain ELECTROSTATICS 67 electrodes, as shown in Fig. 34, are designed to fit the particularparts for which they are intended, and consist of a single wall ofglass. The current enters the electrode from the metal thimbleon the universal handle, and passes through its vacuum and intothe patient throughout the contact of the electrode. The varietiesin general use are: 1, body; 2, vaginal; 3, rectal; 4, laryngeal;.

The insulated variety hasa decided advantage over the plain in that the high-frequency dis-charges are carried directly to the particular parts to be treated,and are not dissipated throughout the whole length of the elec-trode. Fig. 35 represents the vaginal and rectal of the insulated is practically two tubes, the inner one of which is exhausted,while the outer one is at the pressure of the atmosphere. The 68 PRACTICAL ELECTRO-THERAPEUTICS AND X-RAY THERAPY high-frequency discharges are carried to the distal end A, wherethey enter the tissues of the patient as in the plain variety.
