How serious an impediment menstrual troubles are to a woman is indicated by the fact that the women who achieve success and fame seem seldom to be greatly affected by them. To that we may, in part, attribute the frequency with which leaders of the women's movement have treated menstruation as a thing of no importance in a woman's life. Adele Gerhard, and Helene Simon, also, in their valuable and impartial work, _Mutterschaft und Geistige Arbeit_ (p. 312), failed to find, in their inquiries among women of distinguished ability, that menstruation was regarded as seriously disturbing to work. Of late the suggestion that adolescent girls shall not only rest from work during two days of the menstrual period, but have an entire holiday from school during the first year of sexual life, has frequently been put forward, both from the medical and the educational side. At the meeting of the Association of Registered Medical Women, already referred to, Miss Sturge spoke of the good results obtained in a school where, during the first two years after puberty, the girls were kept in bed for the first two days of each menstrual period. Some years ago Dr. G.W. Cook ("Some Disorders of Menstruation," _American Journal of Obstetrics_, April, 1896), after giving cases in point, wrote: "It is my deliberate conviction that no girl should be confined at study during the year of her puberty, but she should live an outdoor life." In an article on "Alumna's Children," by "An Alumna" (_Popular Science Monthly_, May, 1904), dealing with the sexual invalidism of American women and the severe strain of motherhood upon them, the author, though she is by no means hostile to education, which is not, she declares, at fault, pleads for rest for the pubertal girl. "If the brain claims her whole vitality, how can there be any proper development? Just as very young children should give all their strength for some years solely to physical growth before the brain is allowed to make any considerable demands, so at this critical period in the life of the woman nothing should obstruct the right of way of this important system. A year at the least should be made especially easy for her, with neither mental nor nervous strain; and throughout the rest of her school days she should have her periodical day of rest, free from any study or overexertion." In another article on the same subject in the same journal ("The Health of American Girls," Sept., 1907), Nellie Comins Whitaker advocates a similar course. "I am coming to be convinced, somewhat against my wish, that there are many cases when the girl ought to be taken out of school entirely for some months or for a year _at the period of puberty_." She adds that the chief obstacle in the way is the girl's own likes and dislikes, and the
