external treatment, I believe I am justified in attributing his cure almost entirely if not solely to the baths. CASE XI. Mr. * * *, aet. about 50, lawyer, of large, vigorous frame, came to consult me January 4th, 1875. He complained of symptoms that are the frequent results of prolonged mental over-taxation. His intellect was as good as ever, but he lacked his wonted mental endurance and power of application. His mind was perfectly clear, but unable to work. It was a case of “_limited_ cerebral exhaustion.” Physical nutrition was pretty good; yet his color was not normal, being rather paler than it had been and has since become again. His flesh was flabby. There were vague neurotic disturbances, etc., etc. He had until recently occupied a leading public position, and the onerous duties that devolved on him in connection with this, evidently stood in direct etiological relation to his trouble. I ordered an electric bath every other day. This was complied with until the end of February, when the patient had apparently entirely recovered his health, mentally as well as physically. I saw him not very long ago; he looked the picture of health, and told me that he was and had been since I saw him, perfectly well in every respect. CASE XII. Mr. L., aet. 23, presented himself for treatment in October, 1874. He had at various times made the attempt to study some profession, but had never been able to concentrate his mind sufficiently on any object to enable him to persevere in its pursuit. He was fretful, irritable and vacillating; would desire one thing to-day, another to-morrow; never long of the same mind. Melancholia, digestive disturbances and hypochondriacal phenomena accompanied this condition. No organic disease was discoverable. On October 1st he took his first bath. Very shortly after this he commenced the study of medicine. He improved rapidly in every respect. During the month of October he had six baths, which resulted in complete and permanent relief of all the symptoms. He progressed satisfactorily in his studies, and is at the present time taking his second course in one of our city medical colleges. AGRYPNIA. (INSOMNIA; SLEEPLESSNESS).
