Enclose a bipolarvaginal electrode in thepalm of the hand, and, with the sinusoidal current of highfrequency, observe the effects produced as the current-strength.

This experiment willsuggest many therapeutic uses of the sinusoidal current in thepainful and congested conditions of the genito-urinary tract. STATIC CURRENTS 50. The years fashionable drugs come and fade like aline of specters, but the electrostatic machine stays with us.*The history of electrotherapeutics of the static machine may bedivided into two periods: (1) the period of the spark, from1734 to 1880; (2) the period of the spark and spark-gap cur-rents, from 1880 to the present date. The spark-gap currentsare now generally known as Morton currents, having beenoriginated and described by him in a series of articles appear-ing at various dates and in different journals from 1880 to thepresent time. A striking fact that we have verified by extended observationis that when a physician has once acquired a working knowl-edge of a good static machine he continues to use that machineyear after year
