CONDUCTIVE DISCHARGES. 49 equally as good as the terms constant and interrupted used in regard to the older currents of Galvani and static-induced current, first published in the MedicalRecord of March 26, 1881, and later, more fully and ex-plicitly, in the Medical Record of January24, 1891, ante-dated even at the later date all therapeutic consideration ofcurrents of great frequency and high potential. For ten yearsit had been almost unrecognized except by advanced workers. Fig. 30.—a, Revolving Plate ; b, Collectors ; c, Prime Conductorsd. Discharging Rods ; e, Leyden Jars. and, during that period, was the only published current pos-sessed of such qualities. The current was known abroad as the current of Mor-ton. Later the current of dArsonval (Fig. 30) was intro-duced and the consideration of the currents of high fre-quency and high potential came rapidly to be a new elementin electro-therapeutics. The apparatus of dArsonval was theresult of an effort to produce, by transformers and condensers,a current similar to the static-induced current—a current safeof administration, of high frequency and high potential. The static-induced current is represented in the accompany-ing drawing (Fig. 31). To operate this current, d) place the two Leyden jars tobe used in position, connecting the inner coating of the jarswith the corresponding sides of the machine, (2)
