If no controller isemployed in the circuit, use very small Leyden jars, as the -i-. Fig- 31. administration will otherwise be too severe. It is necessary touse some method of changing the character of the current ifLeyden jars of large size, such as are attached to most typesof machines, are employed for this purpose. Dr. Margaret has devised a water rheostat, Fig. 32, which is amodification of the Craido. By this means, it is possible to em-ploy the large-size jars and the longer spark-gap, when thecurrent may be of greater amplitude and less painful thanwhen employed directly to the patient without such device inthe circuit. The static-induced current may be employed in all condi-tions to which the high-tension coil is adapted, and is a usefuladjunct in the treatment of many cases of constipation andpainful neurosis when it is necessary to obtain a very powerfullocal effect. The electrodes employed may be either of metalor covered with felt, sponge, or other s
