1. Its Importance.—Menstruation plays a momentous part in the female economy; indeed, unless it be in every way properly and duly performed, it is neither possible that a lady can be well, nor is it at all probable that she will conceive. The large number of barren, of delicate, and of hysterical women there are in America arises mainly from menstruation not being duly and properly performed.

2. The Boundary-Line.—Menstruation—"the periods"—the appearance of the catamenia or the menses—is then one of the most important epochs in a girl's life. It is the boundary-line, the landmark between childhood and womanhood; it is the threshold, so to speak, of a woman's life. Her body now develops and expands, and her mental capacity enlarges and improves.

3. The Commencement of Menstruation.—A good beginning at this time is peculiarly necessary, or a girl's health is sure to suffer, and different organs of the body—her lungs, for instance, may become imperiled. A healthy continuation, at regular periods, is also much needed, or conception, when she is married, may not occur. Great attention and skillful management is required to ward off many formidable diseases, which at the close of menstruation—at "the change of life"—are more likely than at any time to be developed. If she marry when very young, marriage weakens her system, and prevents a full development of her body. Moreover, such an one is, during the progress of her labor, prone to convulsions—which is a very serious childbed complication.

4. Early Marriages.—Statistics prove that twenty per cent—20 in every 100—of females who marry are under age, and that such early marriages are often followed by serious, and sometimes even by fatal consequences to mother, to progeny, or to both. Parents ought, therefore, to persuade their daughters not to marry until they are of age—twenty-one; they should point out to them the risk and danger likely to ensue if their advice be not followed; they should impress upon their minds the old adage:

5. Time to Marry.—Parents who have the real interest and happiness of their daughters at heart, ought, in consonance with the laws of physiology, to discountenance marriage before twenty; and the nearer the girls arrive at the age of twenty-five before the consummation of this important rite, the greater the probability that, physically and morally, they will be protected against those risks which precocious marriages bring in their train.

6. Feeble Parents.—Feeble parents have generally feeble children; diseased parents, diseased children; nervous parents, nervous children;—"like begets like." It is sad to reflect, that the innocent have to suffer, not only for the guilty, but for the thoughtless and inconsiderate. Disease and debility are thus propagated from one generation to another and the American race becomes woefully deteriorated.

7. Time.—Menstruation in this country usually commences at the ages of from thirteen to sixteen, sometimes earlier; occasionally as early as eleven or twelve; at other times later, and not until a girl be seventeen or eighteen years of age. Menstruation in large towns is supposed to commence at an earlier period than in the country, and earlier in luxurious than in simple life.

8. Character.—The menstrual fluid is not exactly blood, although, both in appearance and properties, it much resembles it; yet it never in the healthy state clots as blood does. It is a secretion of the womb, and, when healthy, ought to be of a bright red color, in appearance very much like the blood from a recently cut finger. The menstrual fluid ought not, as before observed, clot. If it does, a lady, during "her periods," suffers intense pain; moreover, she seldom conceives until the clotting has ceased.

9. Menstruation during Nursing.—Some ladies, though comparatively few, menstruate during nursing; when they do, it may be considered not as the rule, but as the exception. It is said in such instances, that they are more likely to conceive; and no doubt they are, as menstruation is an indication of a proneness to conception. Many persons have an idea that when a woman, during lactation, menstruates, her milk is both sweeter and purer. Such is an error. Menstruation during nursing is more likely to weaken the mother, and consequently to deteriorate her milk, and thus make it less sweet and less pure.

10. Violent Exercise.—During "the monthly periods" violent exercise is injurious; iced drinks and acid beverages are improper; and bathing in the sea, and bathing the feet in cold water, and cold baths are dangerous; indeed, at such times as these, no risks should be run, and no experiments should, for the moment, be permitted, otherwise serious consequences will, in all probability, ensue.

11. The Pale, Colorless-Complexioned.—The pale, colorless-complexioned, helpless, listless, and almost lifeless young ladies who are so constantly seen in society, usually owe their miserable state of health to absent, to deficient, or to profuse menstruation. Their breathing is short—they are soon "out of breath," if they attempt to take exercise—to walk, for instance, either up stairs or up a hill, or even for half a mile on level ground, their breath is nearly exhausted—they pant as though they had been running quickly. They are ready, after the slightest exertion or fatigue, and after the least worry or excitement, to feel faint, and sometimes even to actually swoon away. Now such cases may, if judiciously treated, be generally soon cured. It therefore behooves mothers to seek medical aid early for their girls, and that before irreparable mischief has been done to the constitution.

12. Poverty of Blood.—In a pale, delicate girl or wife, who is laboring under what is popularly called poverty of blood, the menstrual fluid is sometimes very scant, at others very copious, but is, in either case, usually very pale—almost as colorless as water, the patient being very nervous and even hysterical. Now, these are signs of great debility; but, fortunately for such an one, a medical man is, in the majority of cases, in possession of remedies that will soon make her all right again.

13. No Right to Marry.—A delicate girl has no right until she be made strong, to marry. If she should marry, she will frequently, when in labor, not have strength, unless she has help, to bring a child into the world; which, provided she be healthy and well-formed, ought not to be. How graphically the Bible tells of delicate women not having strength to bring children into the world: "For the children are come to the birth, and there is not strength to bring forth."—2 Kings XIX, 3.

14. Too Sparing.—Menstruation at another time is too sparing; this is a frequent cause of sterility. Medical aid, in the majority of cases, will be able to remedy the defect, and, by doing so, will probably be the means of bringing the womb into a healthy state, and thus predispose to conception.
