The last described form of dysmenorrhœa is sometimes attended with spasmodic contraction of the _os uteri_, thus preventing the catamenial flow. This may be readily relieved by applying P. P. to uterus, and N. P. to lower dorsal and upper lumbar vertebræ. MENORRHAGIA. (_Excessive Menstruation._) If the menstrual flow is apt to terminate in hemorrhage, it is best to give _general tonic treatments_, about three times a week, between the periods; and during the last four or five days before color is expected to appear, to take the B D current, medium force, and treat the uterus directly, once a day, with the uterine electrode P. P., while moving N. P. over the dorsal vertebræ, about five to eight minutes, at the close of _general tonic treatment_. If there be no _hemorrhage_, properly, but only too profuse or too long-continued flow of catamenia, the discharge may commonly be stopped by one or two treatments, of eight to ten minutes each, with the uterine electrode, as prescribed above. PROLAPSUS UTERI. (_Falling of the Womb._) Take the B D current, of good medium force, and give _general tonic treatment_ (see page 95), on alternate days, ten minutes, passing briefly over the several parts. After this, treat five to eight minutes with uterine electrode, in the manner prescribed for _menorrhagia_. Then close the sitting by removing the uterine instrument, substituting the sponge-cup as P. P., and treating with it externally, about five minutes, over the pelvic region, while N. P. is stationed on the spine, at the first or second dorsal vertebra. On the _intervening_ days, treat only with the uterine electrode, as above prescribed. LEUCORRHŒA. (_Whites._) Take A D current, _very mild_ force. Introduce the vaginal electrode, N. P., until it meets the uterus, and manipulate with P. P. over the dorsal vertebræ five to eight minutes, three times a week. Once or twice a week, on the intervening days, give _general tonic treatment_. Omit treatment altogether, for one or two weeks, once in two to three months. Considerable time is often required for the cure of old cases. SPERMATORRHŒA. The points to be gained are, to reduce the action of the amatorial organs of the brain and the secretion of the _testes_, and to contract and strengthen the tissue of the seminal vesicles and the prostrate gland.
