Additional matters demanding attention are, as already mentioned, the suitability of the diet, and proper physical exercise. All stimulating articles of food are to be avoided, the excessive use of meat is to be forbidden, and a sufficient mixed diet, containing both animal and vegetable substances, is to be prescribed. Tea and coffee should be taken as sparingly as possible, and alcoholic beverages must be absolutely prohibited. The regulation of the bowels is of great importance. Young girls should accustom themselves to evacuate the bowels every day at a fixed hour, the best time to adopt being either immediately on rising or just after breakfast. Constipation is very apt to lead to the production of irritable conditions of the genital organs. We can point out as a happy instance of modern progress that the practice of certain physical exercises has actually become the fashion for young girls. Gymnastics, with or without apparatus, swimming, skating, and lawn tennis, involve a number of bodily movements advantageous for the health; and in connection with most of these the enjoyment of fresh air offers an additional favorable influence. Bicycling, however, at this period of life is open to many objections, not only on account of the likelihood of direct injury to the genital organs now in course of development, but also on account of the impulse it produces toward onanistic manipulations. Especial attention must be paid to the clothing, regarding which the requirements of fashion so often conflict with those of hygiene, the victory, unfortunately, in most cases falling to the former. The period of the menarche is indeed usually regarded as the proper time for the young girl to begin wearing a corset, if it has not been worn before. In this connection _M. Runge_ makes the significant remark: “As long as bodice and skirt form the two principal articles of woman’s clothing, the corset or some similar article cannot be dispensed with. The vicious features in the corset are its constriction of the thorax, with the object of giving the woman a ‘figure,’ and the introduction into its substance of strips of whalebone or steel in order to give firmness to the figure. The harm done by the former feature, the compression of the abdominal viscera, the corset liver (lacing liver, constricted liver, Ger. _Schnürleber_), the movable kidney, etc.—all are so well known that they need not be particularly described. But the strong pressure from above has a deleterious effect upon the internal genital organs also, leading to passive hyperæmia and to displacements. The ‘bones’ of the corset take part in the compression, and they replace the functions of the muscles of the back. If a woman who has long worn a corset lays it aside later in life, she complains that she is no longer able to hold herself upright. In consequence of insufficient work the muscles of the back have become incapable of keeping the back straight. The corset,
