Here important truths and discoveries are revealed, which may be the means of saving many an affectionate wife and fond mother from a premature grave. How many females marry, who, in becoming pregnant, jeopardize their life, would learn, if they perused these pages, of the discovery by which _pregnancy can be prevented_, by means at once safe, simple, certain, and healthy, and thus many a victim would not fall a sacrifice to the Cæsarean operation. In respect, too, when a woman is threatened with miscarriage or abortion it is important that the treatment, either to prevent it, or, when that is impracticable, to assist and expedite it, should be thoroughly understood, and its treatment made clear and simple, that no unnecessary alarm need be occasioned when it occurs.

MANAGEMENT OF FEMALE COMPLAINTS. MENSTRUATION. One of the principal constitutional characteristics of the female, is menstruation, or the monthly evacuations peculiar to the sex. This important operation generally takes place about the age of twelve or thirteen; but varies through the world, either in degree or frequency, both from constitution and climate. Women in the higher ranks of life, and those of a delicate, nervous constitution, are subject to sickness, headache, and pains in the back and loins, during periodical evacuation. Those of the lower rank, inured to exercise and labor, and strangers to those refinements which debilitate the system, and interrupt the functions essential to the preservation of health, are seldom observed to suffer at these times, unless from general indisposition, or a diseased state of the womb.
