g. 46 shows the general arrangement of the tub and the elec-trodes. Note that the tub is insulated from the sewer connections. Monopolar and Bipolar Methods.—In the monopolar method theelectrode (active) is applied to the body external to the water, thewater acting as the indifferent electrode, carrying the current tothe metallic electrode, which is submerged in the water. With thismethod of application the body carries the whole current, whichenters the body through the active electrode in a concentrated form,the density depending upon the size of the electrode, and emergesfrom the body throughout the distribution of the water. In the CONTROLLING AND MEASURING APPARATUS 81 bipolar bath the body is not in direct contact with either pole,though both poles are in the water. Here the body receives onlya portion of the current as it passes through the water. The largerthe patients body and the closer it is placed to the negative elec-trode, the more current it will be likely to receive.

Fig. 46.—Hydroelectric bath tub. Varieties of Currents Used for Hydroelectric Baths.—The di-rect, alternating, and faradic currents are used in giving the hydro-electric bath, each of which has its particular field of usefulness.We believe these currents are particularly valuable, and should beused much more than they are today, but the great amount ofexpense necessary to equip and maintain such an outfit puts it be-yond the possession of the average electro-therapist. It is only a 82 PRACTICAL ELECTRO-THERAPEUTICS AND X-RAY THERAPY question of time when all well-equipped sanitariums will installa complete hydroelectric bath for the treatment of the many dis-eases for which it is peculiarly adapted. The author can not close this section without sounding a wordof warning to users of the hydroelectric bath where the current isderived from the commercial lighting circuit. The wiring shouldbe so perfectly done that a short with a high voltage current isimpossible. No one should be all
