Sometimes this membrane, when not imperforate, is so thick and strong as to render sexual intercourse impossible, and requires a cutting operation to open the vagina. Several such cases have been operated upon at the Invalids' Hotel and Surgical Institute.

It occasionally happens that the hymen is entire, or imperforate, at birth. This may not be discovered before puberty. But when this period arrives and the menstrual discharge takes place into the vagina, the female will suffer from the retention and accumulation of this secretion, and ultimately a tumor or a protrusion of the membrane which closes the vagina will occur, giving rise to severe pain and other serious symptoms. The retained menstrual fluid, increasing in quantity at every monthly period, dilates the womb as well as the vagina, and even the Fallopian tubes become distended, presenting at length an urgent necessity for relief.

Treatment. This condition admits of relief only by operative surgery. The operation consists in dividing the hymen by a crucial incision, thus allowing the accumulated fluid to be discharged, after which the vagina is cleansed by syringing it with warm water.

Absence of the Ovaries. Let us suppose the case of a young woman who has fully reached the period of puberty without having menstruated. All the organs which we have described, are manifestly developed, she is healthy, vigorous, robust, and able to exercise freely or to engage in laborious occupations. But we notice that her voice is not sweetly feminine, nor is her presence timid, tender, and winning; there is wanting that diffident sexual consciousness, which gently woos, and, at the same time, modestly repels, and tends to awaken interest, curiosity, and desire. Considering also that she has never manifested any inclination to menstruate, we are irresistibly led to the conclusion that the ovaries are wanting; the delicate mustache upon the upper lip, the undeveloped breasts, the coarse features, and her taste for masculine pursuits, all concur in this diagnosis. Thus we account for the harshness of the voice, fitted for command rather than to express the mellow, persuasive cadences of love. Such a malformation cannot be remedied.

Retention and Suppression from Morbid Conditions of the Blood. Non-appearance, as well as suppression of the menses, may result from an abnormal state of the blood. The first condition which demands our attention under this head is plethora. In robust, plethoric females the menses are sometimes very tardy in their appearance, and every month the attempt to establish this function is attended with pain in the head, loins, and back, chilliness, nausea, and bloating of the abdomen. Sometimes there is intolerance of light or sound, and cerebral congestion, amounting almost to apoplectic symptoms. The pulse is full and strong, the blood abundant and surcharged with red corpuscles. Such persons may be accustomed to luxurious living, and there is evidently a predisposition to abnormal activity of the alimentary functions.

Treatment. We may briefly suggest that such subjects should engage in laborious physical exercise in order to expend the surplus of vitality, and should lessen the daily amount of food taken, and use that which is light and unstimulating. We should also prevent the determination of blood to the head, by keeping it cool and the feet warm, and by increasing the flow of blood to the extremities. The volume of the circulation may be diminished by acting upon the natural outlets, such as the skin, kidneys, and bowels. The proper means and appliances for quickening the circulation of the blood are indicated, and friction upon the surface, bathing, the daily use of such cathartics as Dr. Pierce's Pleasant Pellets, and, finally, the use of some general uterine stimulant, such as Dr. Pierce's Favorite Prescription, will generally prove successful in cases of amenorrhea resulting from plethora.

Retention and Suppression from Anæmia. To describe the condition of the patient whose blood is low and deprived of the richness, warmth, and bloom, it once possessed when it kindled admiration and enthusiasm in others, is but to give a picture of a numerous class of female invalids. It is sad to see beauty fading, vigor waning, and Bright's disease or consumption slowly wasting the blood and consuming the vital cells, until the spirit can no longer dwell in its earthly abode and death claims the skeleton for dust.

Chronic Decline, with its attendant anæmia, may be induced by bad habits, destitution, or constitutional depravity. Sickly forms, wrecks of health, address our senses on every side. All these subjects evidently once had a capital in life, sufficient, if properly and carefully husbanded, to comfortably afford them vital stamina and length of days. Alas! they have squandered their estate, perchance in idleness and luxurious living, or have wasted it in vanities or misdirected ambition. Having become bankrupts in health, there is necessarily a failure of the menstrual function, and then follows a panic. All the blame of the insolvency and general derangement, is unjustly attributed to the non-performance of the duties of the uterus. Thus, this organ is altogether dependent Upon the general health for its functional ability, yet frequently treatment is instituted to compel menstruation, regardless of the condition of the system. Thus the enfeebled uterus is wrongfully held responsible for general disorder, because it ceases to act, when by acting it would further deplete the blood and thus materially contribute to the already existing chronic decline.

No matter what are the causes of this decline, whether they are the follies of fashion, the effect of indolence, debility in consequence of insufficient food, perversion of nutrition by irregular habits, lack of exercise, or the taking of drastic medicines, the result is anæmia and amenorrhea.

Treatment. We would suggest in such cases a nutritious diet, increased exercise, cleanliness, regular habits, hard beds, and useful employment. The diet may be improved by animal broths, roasted meats, fresh beef, mutton, chicken, or eggs, and the dress should be comfortable, warm, and permit freedom of motion. The patient should indulge in amusing exercises, walking, swinging, riding, games of croquet, traveling, singing, percussing the expanded chest, or engage in healthful calisthenic exercises. The hygienic treatment of this form of amenorrhea, then, consists in physical culture, regular bathing, and the regulation of the bowels, if constipated, as suggested in this volume under the head of constipation.
