THE SIGNS AND CHANGES OF PUBERTY In the girl the sign of puberty is the growth of hair about the pubes, private organs and armpits. Her whole frame remains more slender than in the male. Muscles and joints are less prominent, limbs more rounded and tapering. Internal and external organs undergo rapid enlargement, locally. The _mammae_ (the breasts) enlarge, the ovaries dilate, and a periodical uteral discharge (menstruation) is established. MENSTRUATION No young girl should feel alarmed if, owing to the negligence of her parents or guardians to prepare her, she is surprised by this first flow from the genital organs. Puberty is the proper time for the appearance of menstruation. This is the periodical development and discharge of an ovule (one or more) by the female, accompanied by the discharge of a fluid, known as menses or catamenia. Menstruation, in general good health, should occur about every twenty-eight days, or once in four weeks. This rule, however, is subject to great variation. Menstruation continues from puberty to about the forty-fifth year, which usually marks the _menopause_, or "change of life." When it disappears a woman is no longer capable of bearing children. Her period of fertility has passed. In rare cases menstruation has stopped at 35, or lasted till 60. HINTS FOR OBSERVANCE DURING MENSTRUATION When the period arrives a girl or woman has a feeling of discomfort and lassitude, there is a sense of weight, and a disclination for society. Menstruation should not, however, be regarded as a nuisance; a girl's friends respect her most when she is "unwell." She should keep more than usually quiet while the flow continues, which it will do for a few days. Also, she should avoid all unnecessary fatigue, exposure to wet or to extremes of temperature. Some girls are guilty of the crime of trying to arrest the menstruation flow, and resorting to methods of stopping it. Why? In order to attend a dance or pleasure excursion! Lives have been lost by thus suppressing the monthly flux. Mothers should instruct their daughters when the menses are apt to begin, and what their function is. During menstruation great care must be taken in using water internally. A chill is sufficient to arrest the flow. If menstruation does not establish itself in a healthy or normal manner at the proper time, consult a physician in order to remove this abnormal condition. Any disturbance of the delicate menstrual functions during the period, by constrained positions, muscular effort, brain work and mental or physical excitement, is apt to have serious consequences.
