Take the A D current. If any symptoms exist of an effort of nature to bring on the menses, note the _time_ of them, and regard it, in the treatment, as the proper monthly period. If no symptoms of such a period are perceptible, the practitioner must _fix_ upon a time for it, and regard it accordingly. About four to six days before the periodic time, commence to treat as follows, using a _moderate force_: Insert the uterine electrode, N. P., wet in warm water, per vagina, until it meets the uterus; and manipulate with P. P. over the dorsal and first two lumbar vertebræ, and more or less over the back on both sides of the spinal column, some six or eight minutes daily, down to the period fixed upon for the catamenia to appear. If they do not start, let the patient rest for some four or five days, and then begin with _general tonic treatment_. (See page 95.) Continue this, three times a week, until within a little less than a week of the _periodic_ time, when the same treatment with the uterine electrode as was at first employed should be resumed, and again be continued to the time assigned for the menses. If no success should appear, return, after a few days, to _general tonic treatment_ as before. Let these forms of treatment be prosecuted until success crowns the effort. Ordinarily, not many months--perhaps not more than one or two months--will be required; especially, if the treatment be aided, on the part of the patient, by a good degree of moderate exercise in the open air, and a free, nourishing diet. AMENORRHŒA. (_Suppressed Menstruation._) Treat as for _chlorosis_. But if the case be recent--the effect of taking cold--begin, in the first few sittings, to treat eight or ten minutes as for common cold; then conclude the sitting by treating, about as many minutes, in the same manner as prescribed for chlorosis. DYSMENORRHŒA. (_Painful Menstruation._) If the disease be occasioned by uterine displacement, obstructing the _os uteri_, the organ must be restored to its normal position. This can best be done by mechanical action. But it is most commonly occasioned by irritation of the mucus membrane lining the interior cavity of the uterus. Mucus surfaces, under _chronic_ irritation, are electrically negative. Therefore, in this case, if it be an _old_ one, taking the A D current, _very mild force_, apply the uterine electrode, N. P., to the _os uteri_, and treat over the lower dorsal and upper lumbar vertebræ with P. P., _long cord_. Treat five to eight minutes, three times a week. But I should add, that recovery from this infirmity, when occasioned by uterine irritation, will be much aided by commencing each sitting with a _general tonic treatment_ (see page 95), and closing with the treatment just above prescribed.
