Before considering more direct measures for establishing menstruation it may be well to recall to mind the two elements of the function--ovulation and the uterine flow. The first, the prime factor, we can not influence by any medicines nor by any mode of treatment except, perhaps, by electricity. Observation of animals shows that mere proximity of the male influences it plainly, but this only indicates a line along which we cannot prescribe. An opinion may, however, be asked in regard to the propriety or advisability of marriage for a woman who has never menstruated. In such case no advice should be given until after a thorough local examination, and its tenor will then be in accord with the condition of the organs. With such atresia or absence of organs as not to permit sexual intercourse marriage should be positively negatived. In such cases as those of partially-developed or absent uterus the facts should be laid before the parties interested and the decision referred to them. In the former class of cases some hopes of improvement may be entertained. The second factor of menstruation, the flow, we can influence by such measures as cause a more or less intense pelvic congestion. The ovaries sharing in this congestion, it is not impossible that ovulation is in some {190} degree also promoted, but it can be only to a minor degree and when the ovaries are in a favorable condition. The uterus is the principal organ to be affected, and to it the most of these measures are addressed. Direct treatment for the establishment of menstruation should be first of a character rather to solicit than to force the flow. These measures act best where, the general health having been restored, the flow does not appear, but the premonitory symptoms are present. Rest in bed, warmth to the pelvic region by poultices or other means, and hot drinks, are to be prescribed; among the latter infusions of pennyroyal, some of the mints, tansy, and cotton-root have a high domestic reputation and should be preferred. Hot pediluvia or hot sitz-baths, prolonged to twenty or thirty minutes, may be taken at bedtime. These may be rendered sufficiently stimulating to irritate the skin by the addition of mustard. More active measures are stimulating enemata and vaginal injections--for the former ten grains of aloes in mucilage, and for the latter liquor ammonia in milk, fluidrachm j-pint j, gradually increasing the strength to production of slight leucorrhoea. Both these have the endorsement of high authority. Such measures should be used or plied more assiduously about the period, when that is known. During the interval a tonic course is almost always required, and a powerful local influence can be exerted by cold sitz-baths of brief duration, say one or two minutes, once daily, followed by vigorous rubbing with a coarse towel or a flesh-brush.
