Beginning with the simplest and easiest exercises of chamber gymnastics, the girl gradually proceeds to more difficult and elaborate exercises and to the use of medico-mechanical apparatus. The clothing of young girls at the time of the menarche must receive attention to this extent, that all articles of clothing should be rejected which increase the tendency already existing to hyperæmia of the genital organs or offer any hindrance to the circulation in general. Above all, the physician must take his part in the contest so long and so vainly urged against the corset. But further, all tight clothing, such as restricts the freedom of movement of the thorax and the abdomen, tight collars, and tight garters—all these must be forbidden; moreover excessively warm underclothing, of the lower extremities especially, which may stimulate the genital organs, must also be prohibited. As regards the night hours, a thick feather bed is unsuitable. The young girl should sleep on a hair mattress, and the bed clothing should be light. Eight to nine hours sleep is sufficient; in the words of the English proverb, “early to bed and early to rise, is the way to be healthy, and wealthy, and wise.” To live by rule, with regular hours of work and suitable pauses for rest, is of great importance. Among the well-to-do classes also care should be taken that the adolescent girl takes moderate physical exercise for several hours daily; she should go for a good walk, and not spend hour after hour recumbent upon a sofa in idle reverie. Sitting for too long a time, whether engaged in sewing or at the piano, is harmful; working at the sewing-machine is permissible for short periods only, and is indeed at this period of life better altogether avoided. Bicycling is also an unsuitable exercise at this age and readily leads to masturbation. Lawn tennis and croquet, on the other hand, are very suitable active open-air games; in winter, skating may be indulged in if proper precautions are taken against chill; in summer, swimming and rowing. The reading of light literature should be kept under supervision; equivocal novels, such as may give rise to erotic reverie and sensual excitement, must be strictly forbidden. A watch should be kept for any indications of the habit of masturbation; and if the habit exists, appropriate measures should be taken.
