Electricity is the most reliable emmenagogue, and has such an amount of testimony in its favor as not to permit a doubt as to its value. It is the only direct uterine or menstrual stimulant except permanganate of potassium. Statical electricity is now but little used, although Golding-Bird published striking instances of its efficacy in amenorrhoea at an early day in its therapeutic history. Faradization is now most frequently resorted to. One pole is to be applied to the sacrum and the other above the pubes or over either ovary. The internal application of the current is much more powerful as well as less painful. It is administered by applying a cup-shaped electrode to the cervix, or by introducing an insulated sound into the uterus, the other electrode being external as before. The séances should be repeated every second or third day, and should be more frequent just before the periods when their time is known. Beard and Rockwell insist that general electrization should be administered at the same time, and Mann passes the constant current through the organs during the intervals and the faradic at the periods. Simpson originated {192} a galvanic intra-uterine pessary, which Thomas has modified. It is doubtful whether the feeble current generated by these instruments produces any effect, or whether they act simply as mechanical irritants. When they are used, it should be borne in mind that there is eminent and high authority against the use of intra-uterine pessaries of any kind, and that all agree that a patient to whom one is applied should be kept under careful observation. It must be stated that good results have been obtained with this class of local remedies in cases which would seem extremely unpromising--even in those in which amenorrhoea depends upon partially-developed organs. There is most positive testimony of the highest character as to good effects obtained in increasing development and promoting the flow.
