. Electricity : its medical and surgical applications, including radiotherapy and phototherapy . ttered as in Fig. 187. i, i, static universal electrode in circuit. Upon grasping the two elec-trodes and drawing the two brass balls, i, i, of the circuit-breaking electrode apart a current is feltcausing vigorous muscular contractions in ratio with the distance apart of the balls, i, i, and as longas sparks will pass between them. Patient insulated. Method applicable to small machines. (Morton.) the two adjustable metallic balls on the electrode for that distance apart of these and consequent strength of current whichit is desired to have is regulated by the finger of the operator. It maybe employed in one of two ways—either without condensers, whenthe arrangement is as in Fig. 189, or by using condensers, as in 234 METHODS OF PRODUCING LOCAL ELECTRIFICATION Fig. 190. When using this electrode the patient must be insulated,one cord being attached to the insulating platform, while the otheris grounded; only one electrode (the pistol electrode) is applied to the Fig. 190. Static universal electrode. In primarj circuit grounded. Patient, condensers, and circuit breakerin same circuit. Patient on an insulated platform as in giving sparks. Lettering as in Fig. 187,except that /, / is grounded pole of macliine and connection to platform; P, person insulated; G,grounded chain from universal electrode, having curved handle, to be held by administrator andapplied upon the person of the insulated subject, strength of current graduated by the finger andadjustable balls of circuit breaker. (Morton.) patient, and this must be also grounded by a metal chain passing to thesame object on which the cord is grounded. Fig. 191
