A system of electrotherapeutics as taught by the International correspondence schools, Scranton, . Fig. 11Kennelly Sinusoidal Apparatus 20 per cent. In chronic congestion of the different organs ofthe body, a marked diminution of their size is observed after acourse of sinusoidal baths. The importance of this action incardiac and hepatic conditions is obvious. The secretion ofurine is also considerably increased. The current serves tostimulate the muscles of the peripheral capillaries, which are 28 ELECTRICITY IN §19 paretic from distension. This energy imparted to the peripheralcirculation gives new vigor and tone to the central organ ofcirculation. The genito-urinary surgeon will find in this current a reliabletherapeutic agent in various pathological conditions that arevery common in his routine practice. 48. Sinusoidal Apparatus.—For physicians who havethe alternating current in their office, a very efficient sinusoidalapparatus has been arranged in the following manner by(iautier <t Larat: The current is taken directly from a 110-volt. Pio. 12 .V. Intush Sinusoidal Apparatus alternating current with a 30-eandlepower lamp interposed as aresistance. The current is then conducted directly from thelamp to the primary of an induction-coil. The current usedin the bath is taken from a secondary coil constructed on theDubois-Reymond type, Fig. 10. In this arrangement the fre-quency of the street-current cannot be changed. The current-strength is regulated by the degree in which the secondary coiloverlaps the primary. The Kennedy sinusoidal apparatus isvery convenient and serviceable, Fig. 11. For its use the 110-volt direct current is required. Another sinusoidal apparatusnow in very general use is manufactured by the Mcintosh Bat-tery and Optical Company, Fig. 12. §19 GENITO-URINARY DISEASES 29 49. The general bath, as a means of administering thesinusoidal current, necessitates disrobing. This is somewhatinconvenient and requires some time. A very efficie
