friction of an imperfectly developed reproductive apparatus. Doubtless the evil of her education will infect her whole life. The next case is drawn from different social surroundings. Early associations and natural aptitude inclined Miss B---- to the stage; and the need of bread and butter sent her upon it as a child, at what age I do not know. At fifteen she was an actress, determined to do her best, and ambitious of success. She strenuously taxed muscle and brain at all times in her calling. She worked in a man's sustained way, ignoring all demands for special development, and essaying first to dis-establish, and then to bridle, the catamenia. At twenty she was eminent. The excitement and effort of acting periodically produced the same result with her that a recitation did under similar conditions with Miss A----. If she had been a physiologist, she would have known how this course of action would end. As she was an actress, and not a physiologist, she persisted in the slow suicide of frequent hemorrhages, and encouraged them by her method of professional education, and later by her method of practising her profession. She tried to ward off disease, and repair the loss of force, by consulting various doctors, taking drugs, and resorting to all sorts of expedients; but the hemorrhages continued, and were repeated at irregular and abnormally frequent intervals. A careful local examination disclosed no local disturbance. There was neither ulceration, hypertrophy, or congestion of the os or cervix uteri; no displacement of any moment, of ovarian tenderness. In spite of all her difficulties, however, she worked on courageously and steadily in a man's way and with a woman's will. After a long and discouraging experience of doctors, work, and weaknesses, when rather over thirty years old, she came to Boston to consult the writer, who learned at that time the details just recited. She was then pale and weak. A murmur in the veins, which a French savant, by way of dedication to the Devil, christened _bruit de diable_, a baptismal name that science has retained, was audible over her jugulars, and a similar murmur over her heart. Palpitation and labored respiration accompanied and impeded effort. She complained most of her head, which felt "queer," would not go to sleep as formerly, and often gave her turns, in which there was a mingling of dizziness, semi-consciousness, and fear. Her education and work, or rather method of work, had wrought out for her anemia and epileptiform attacks. She got two or three physiological lectures, was ordered to take iron, and other nourishing food, allow time for sleep, and, above all, to arrange her professional work in harmony with the rhythmical or periodical action of woman's constitution. She made the effort to do this, and, in six months, reported herself in better health--though far from well--than she had been for six years before.
