Women of languid disposition and relaxed muscles are frequently urged to 'take exercise,' and to 'go to work.' Their condition sometimes excites censure rather than commiseration, because it is thought that they do not exert, and thus strengthen, themselves as much as they should. We are quite as much in favour of work and vigorous muscles as any one. But often it were the most foolish advice possible to give a woman, to tell her to seek active exercise. It is just what she should avoid, as it may ultimately give rise to that very trouble which, now only threatening, is the cause of her listlessness. Many instances are familiar to every physician of extensive experience, where a long walk, a hard day's work, a vigorous dance in the evening, or a horseback ride, has left behind it a uterine weakness which has caused years of misery. Especially after confinement or premature delivery it is prudent for a woman to avoid any such exertion for months and months. Moderate employment of her muscles in any light avocation, short walks and drives, fresh air, with judicious exercise,--these are well enough in every instance, but beyond them there is danger. We know too well that advice like this will sound like mockery to some who read these lines. They have to work, and work hard; they have no opportunity to spare themselves; the iron hand of necessity is upon them, and they must obey. We can but sympathize with them, and cheer them with the consolation that many a woman has borne all this and lived to a healthy and happy old age. Nature has surrounded the infinitely delicate machinery of woman's organization with a thousand safeguards, but for all that, the delicacy remains; and it is because so many women are forced to neglect their duties to their ownselves, that so many thousands walk the streets of our great cities, living martyrs. But no. We must modify what we have just written. In justice to our own sex, and in all truthfulness, we cannot allow the blame to be removed altogether from women themselves. They alone are responsible for one of the most fruitful causes of their wretchedness. The theme is a threadbare one. We approach it without hardly any hope that we shall do good by repeated warnings utterly monotonous and tiresome. But still less can we feel comfortable in mind to pass it over in silence. We refer to the foolish and injurious pressure which is exerted on the lower part of the chest and the abdomen by tight corsets, belts, and bands to support the under-clothing; in other words, TIGHT LACING.
