STATIC ELECTRICITY. 55 2. A current of remarkable potency may be produced bymodifying the wave-current as follows: The usual connectionshaving been made and the electrode placed upon a surface requir-ing an intense local application, place a second electrode or plateindifferently on any part of the body or on a part requiring amilder local treatment, and connect the latter electrode or platewith the inner coating of a Ley den jar, the outer coating ofwhich is connected by direct metallic connection with the spark-gap between the balls of the discharging rods will beemployed to control the current strength. With these currents, above described, the intensity ofelfect produced upon the patient is greater on the side connected. Fig. 42.—The wave-current intensified. (Morton.) with the machine than on the side connected with the ^externalcapacity^ or the Leyden jar having a ground connection from theouter coating. In these modified currents the administration is madewith the patient insulated and the effect is local to a marked, andconstitutional to a very moderate, degree. Whereas the unmodi-fied wave-current is constitutional in a very large measure, butrequires more energy in the static machine to produce the samedegree of local effect. The intensity of these currents may be varied with the sizeof the external capacity, the size of the Leyden jar, the size andproximity of the electrode, or the length of the spark-gap andthe speed and capacity of the machine. 56 ELECTRO-THERAPEUTICS. As a great deal of misunderstanding seems to exist as tohow the wave-current should be administered, I give here own words:— One prime conductor of the static generator is gr
