CASE IX.* Mrs. E., from the _clientele_ of Dr. KREHBIEL, aet. 28, married, of an exceedingly nervous temperament, had suffered from excessive nervous irritability and prostration since her last confinement (about a year previous to my seeing her). There was no organic trouble, the symptoms pointing to pure functional hysteria. She was sent for electro-balneological treatment April 21st, 1874. Six baths, in which both currents were employed, restored her to perfect health. NEURASTHENIA. (NERVOUS EXHAUSTION.) Those who are familiar with the pre-eminent qualities as a neurotic of electricity, will not be surprised to be told of the beneficial effects in the condition under consideration of electric baths. It is not only in _general_ nervous exhaustion, however, that electric baths exercise this salutary influence, but in the condition known as _cerebral exhaustion_ likewise. Judging from my own experience, their efficacy in this latter condition is far greater than that of local applications, whilst they are unattended with any of the irritant and other disagreeable effects that even with the greatest care and caution we cannot always disassociate from galvanization of the brain. They no doubt act here in two ways, i.e., first and chiefly, through reflex influence from the entire periphery; second, by derived currents on the brain directly. Whatever their mode of action, the results obtained are of the most gratifying kind. The pitiable condition in which some patients of this class present themselves, is familiar enough to every physician; but it appears that the greater the degree of exhaustion and the more prostrate the various functions, the more striking are the effects of the baths. The patients seem to live up anew under their influence. While in many if not most other complaints that come under electro-balneological treatment, a certain number of baths are requisite in order to get discernible effects, in the disease under consideration each bath, except perhaps the first, is followed by more or less immediate improvement, which, if the treatment is persevered in, remains permanent.
