This is an English work on electrotherapy. The author started, as he says, with some skepticism as to the value of these currents, but after an extensive trial became convinced of their great usefulness in some cases. The book is largely made up of a description of the apparatus. The diseases in which he has found the treatment beneficial are briefly noticed at the end and include diabetes, gout, chronic rheumatism, obesity, hysteria, anemia, chlorosis, neurasthenia and pulmonary tuberculosis. The latter is treated of at considerable length, and he finds this treatment of marked benefit. He is strongly of the opinion that the application or use of these currents in tuberculosis sanitaria will greatly increase the number of cures. Dyspepsia is also discussed at some length. Among local diseases he mentions lupus, both of the tubercular and erythematous types, eczema, sciatica, headache, etc., and malignant growths.
