Within the last fifteen years, probably no one branch of medical science has received greater attention at the hands of physicians than this of diseases of women. Many hitherto inexplicable cases of disease, much suffering referred to other parts of the system, have been traced to local misfortunes of the character we have just described. Medical works are replete with cases of the highest interest illustrative of this. We are afraid to state some of the estimates which have been given of the number of women in this country who suffer from these maladies; nor do we intend to give in detail the long train of symptoms which characterize them. Such a sad rehearsal would avail little or nothing to the non-medical reader. It is enough to say, that the woman who finds herself afflicted by manifold aches and pains, without obvious cause; who suffers with her head and her stomach and her nerves; who discovers that, in spite of the precepts of religion and the efforts of will, she is becoming irritable, impatient, dissatisfied with her friends, her family, and herself; who is, in short, unable any longer to perceive anything of beauty and of pleasure in this world, and hardly anything to hope for in the next,--this woman, in all probability, is suffering from a displacement or an ulceration of the uterus. Let this be relieved, and her sufferings are ended. Often a very simple procedure can do this. We recall to mind a case described in touching language by a distinguished teacher of medicine. It is of an interesting young married lady, who came from the Southern States to consult him on her condition. She could not walk across the room without support, and was forced to wear, at great inconvenience to herself, an abdominal supporter. Her mind was confused, and she was the victim of apparently causeless unpleasant sensations. She was convinced that she had been, and still was, deranged. The physician could discover nothing wrong about her system other than a slight falling of the womb. This was easily relieved. She at once improved in body and mind, soon was able to walk with ease and freedom, and once more enjoyed the pleasure of life. In a letter written soon after her return home, she said, 'This beautiful world, which at one time I could not look upon without disgust, has become once more a source of delight.' How strongly do these deeply felt words reveal the difference between her two conditions! There is one source of great comfort in considering these afflictions. It is, that they are in the great majority of cases traceable to CAUSES WHICH ARE AVOIDABLE. Most of them are the penalties inflicted by stern nature on infractions of her laws. Hence the great, the unspeakable, importance of women being made aware of the dangers to which they are exposed, and being fully informed how to avoid them. This task we now assume.
