CASE XXV.* _Perfect impotency._—Mr. F., from the practice of Dr. CARO, a robust gentleman, aet. thirty-six, full of muscular vigor. Had had syphilis, the symptoms of which had disappeared under Dr. C.’s treatment. For two years the power of erection as well as sexual appetite had become extinct—if we except an occasional imperfect spontaneous erection on waking up in the morning, and even this was of rare occurrence. Ordinary medication proving inadequate, Dr. C. sent patient to take electric baths. From March 7th to July 16th, Mr. F. used the baths, averaging about two weekly. He was then, and still remains, perfectly restored. CASE XXVI. _Perfect impotency._ A. E. K., aet. 23, commercial traveler, applied to me for treatment in the spring of 1873. His general health was very good. He had masturbated but little. Had been in full possession of his sexual power until almost twenty-two years of age, when he found that, without assignable cause, he had lost the power of erection. His general condition being, as far as discoverable, perfect in every respect, I instituted a local electrical treatment. This was continued for some time without avail. Strychnia was then administered with no better result, and after some months’ treatment I told him that I could do nothing for him. He remained without any treatment whatever until the spring of 1874, when I advised him to try electric baths. He took in all about half a dozen baths, which resulted in his complete and thus far permanent restoration. CASE XXVII. _Sexual debility._ Mr. W., aet. 32, married, manufacturer, consulted me in February 1875. Had gradually for about a year past lost sexual power. Was able to perform the marital act at rare intervals only, and when he did, felt exhausted the whole of the succeeding day. I ordered him electric baths. He took the first on February 22d, 1875. Between this date and March 22d, he took six baths. The sexual power had then fully returned. I must not omit to state that during the time he was under treatment he took, by my direction, gr. 1/25 phosphorus twice daily, which may have somewhat accelerated the result. CONSTIPATION.
