If the electrode be a metal one, the electricity Is drawn rapidly fromthe patient at the point which is nearest to the electrode, and a sensationresembling that of a breeze is experienced at the spot where tlieelectricity escapes. Single or multiple points may be employed on theelectrode. ^ In either of these methods, when the electrode is composed of tvood,the sensation is modified, to a certain extent, by the poor conductivityof the wooden point. Most patients compare the effect of such an appli-cation to a shower of sand concentrated upon the point of withdrawalof the charge. When this method is employed about the eye, the wooden ball orwooden point is usually preferable to one of Fig. 1S3.—The Electrical Head-Bath, a Variety of Administration of the Static Breeze. When application to the head and scalp are deemed requisite, ametal cap studded Avitli points is hung over the head of the patient by achain, wdiich is grounded. This cap is known as the umbrella elec-trode. It should not touch the patients head or hair, when he is placedbeneath it upon the insulated platform. The numerous points of theelectrode draw oft the electricity through the hair and scalp, which passesfrom the machine to the patient, and produce a sensation which is i)ar-ticularly pleasant. A strong wind is felt permeating the hair andencircling the head.
