In the treatment for curative results, a mild currentis held to be most efficient (Chvostek). An electrode— Fig. Exophthalmic goitre. the anode—is placed in the angle behind the jaw, and thecathode on the epigastrium, and a stabile current is allowedto flow for three to five minutes. The cervical spine shouldalsobe galvanized. It may be included in the circuit, byplacing the anode over the vertebra in turn, whilst the 15 226 ELECTRO-THERAPEUTICS. cathode rests on the epigastrium. Stabile may be variedby labile applications. The faradic current may also beused successfully, an instance of this having come undermy notice. The first published cases illustrating the cura-tive value of galvanism, were those of Chvostek, who fol-lowed with a new series of examples the next year,2 whenMeyer3 also reported several cases. In 1874, I read a paperbefore the medical section of the American Medical Asso-ciation, advocating this plan of treatment, and illustrated itsadvantages by the details of five cases
