Illustrations of this sort might be multiplied but these three are sufficient to show how an abnormal method of study and work may and does open the flood-gates of the system, and, by letting blood out, lets all sorts of evil in. Let us now look at another phase; for menorrhagia and its consequences are not the only punishments that girls receive for being educated and worked just like boys. Nature's methods of punishing men and women are as numerous as their organs and functions, and her penalties as infinite in number and gradation as her blessings. Amenorrhoea is perhaps more common than menorrhagia. It often happens, however, during the first critical epoch, which is isochronal with the technical educational period of a girl, that after a few occasions of catamenial hemorrhage, moderate perhaps but still hemorrhage, which are not heeded, the conservative force of Nature steps in, and saves the blood by arresting the function. In such instances, amenorrhoea is a result of menorrhagia. In this way, and in others that we need not stop to inquire into, the regimen of our schools, colleges, and social life, that requires girls to walk, work, stand, study, recite, and dance at all times as boys can and should, may shut the uterine portals of the blood up, and keep poison in, as well as open them, and let life out. Which of these two evils is worse in itself, and which leaves the largest legacy of ills behind, it is difficult to say. Let us examine some illustrations of this sort of arrest.
