As long ago as 1901 my attention was called to the therapeutic value of electricity administered through the medium of warm water in a bath by my friend Dr. Lewis Jones, Physician in Charge of the Electrical Department, St. Bartholomew's Hospital, London. He considers this is the best means of employing electricity for general therapeutic purposes, describing it in his work on medical electricity as a method of great value whenever general stimulating and tonic effects are required. In this work will also be found reference to the treatment, some years since, of eighteen males and five females at Claybury Asylum by Dr. Robert Jones, with results which he considered satisfactory. In these induction coil currents were used in the bath. The method appeared to me likely to prove much more convenient and practical than the usual methods of faradism and galvanism, which do not lend themselves to the purposes of general as apart from special and local application. Largely, I think, for the lack of a convenient method of general application, electrical treatment has been almost discarded, at any rate in this country, in mental diseases. I hope in this communication to show that this therapeutic means is one which should not be neglected.
