As I have before observed, the catamenia usually appear at from the fourteenth to the fifteenth years of age. Now, when there is a failure on the part of nature to bring about this state of things, there is not unfrequently a great deal of anxiety experienced on the part of mothers and those most intimately concerned. If, likewise, the girl at this time is attacked with any particular ailment, it is almost sure to be attributed to this cause. Too often, under these circumstances, she is also subjected to various modes of medical treatment, with the view of forcing nature into that sort of work which it is believed she ought to do, but will not. Now, the effect of such a course can be only harmful, as a general fact. To aid nature, it should be remembered that we must _increase_ her powers, and not _diminish_ them, as is almost necessarily the case if a course of drug-medication is practiced. Please notice, then, that I wish to persuade you that this plan of drugging the system for tardy menstruation is a most unwise and unnatural one. Attend well to nature, and nature will take care of herself. Let me give you a few words from an honest, good man, Dr. Dewees, who years ago went to his long home. He says: “Our exertions in favor of such patients, should tend to the invigoration of the system in general, and the development of the uterine system in particular. The first should be attempted—First: By the establishment of a regular course of exercise; such as riding on horseback, when practicable; walking in proper weather; skipping the rope within doors, when the weather will not permit exercise abroad; dancing moderately, and with strict regard not to become overheated, and cooling too suddenly. Secondly: By proper attention to dress; wearing flannel next the skin in cold weather, and properly protecting the feet and legs against cold; carefully avoiding damp and wet places, and partial streams of cold air, especially when warm. Thirdly: By a diet of easily-digested substances, both of the vegetable and animal kind; avoiding all stimulating drinks, such as wine, spirits, or beer, etc., under the specious pretext of their being strengthening.” I give you these words, not that I would altogether agree with every idea advanced, but because of the general worth and correctness of the remarks, and the high authority from which they come. I do not believe it best for any one to wear flannel next to the skin, but I _do_ believe in guarding the body sufficiently against cold, a thing which young ladies too often neglect. Dancing, too, as a general rule, cannot be regulated in the way it should be; and as for animal food, it is not necessary, to say the least.
