The following case illustrates one of the ways in which our present school methods of teaching girls generate a menorrhagia and its consequent evils. Miss A----, a healthy, bright, intelligent girl, entered a female school, an institution that is commonly but oddly called a _seminary_ for girls, in the State of New York, at the age of fifteen. She was then sufficiently well-developed, and had a good color; all the functions appeared to act normally, and the catamenia were fairly established. She was ambitious as well as capable, and aimed to be among the first in the school. Her temperament was what physiologists call nervous,--an expression that does not denote a fidgety make, but refers to a relative activity of the nervous system. She was always anxious about her recitations. No matter how carefully she prepared for them, she was ever fearful lest she should trip a little, and appear to less advantage than she hoped. She went to school regularly every week, and every day of the school year, just as boys do. She paid no more attention to the periodical tides of her organization than her companions; and that was none at all. She recited standing at all times, or at least whenever a standing recitation was the order of the hour. She soon found, and this history is taken from her own lips, that for a few days during every fourth week, the effort of reciting produced an extraordinary physical result. The attendant anxiety and excitement relaxed the sluices of the system that were already physiologically open, and determined a hemorrhage as the concomitant of a recitation. Subjected to the inflexible rules of the school, unwilling to seek advice from any one, almost ashamed of her own physique, she ingeniously protected herself against exposure, and went on intellectually leading her companions, and physically defying nature. At the end of a year, she went home with a gratifying report from her teachers, and pale cheeks and a variety of aches. Her parents were pleased, and perhaps a little anxious. She is a good scholar, said her father; somewhat over-worked possibly; and so he gave her a trip among the mountains, and a week or two at the seashore. After her vacation she returned to school, and repeated the previous year's experience,--constant, sustained work, recitation and study for all days alike, a hemorrhage once a month that would make the stroke oar of the University crew falter, and a brilliant scholar. Before the expiration of the second year, Nature began to assert her authority. The paleness of Miss A's complexion increased. An unaccountable and uncontrollable twitching of a rhythmical sort got into the muscles of her face, and made her hands go and feet jump. She was sent home, and her physician called, who at once diagnosticated chorea (St. Vitus' dance), and said she had studied too hard, and wisely prescribed no study and a long vacation. Her parents took her to Europe. A year of the sea and the Alps, of
