No conscientious physician can give thought to this subject without being profoundly stirred. It may justly be said that all types of disease affecting the general health, the happiness, and the efficiency of the people are equally important, and should elicit the same degree and quality of kindly consideration.

The dominating reason which renders diseases of women an exception to this rule may be mentioned here, however, so that the reader will keep its supreme significance prominently in mind while considering the subject in its various other aspects. "Diseases of women" rank first as a eugenic problem. They have a direct and far-reaching influence on posterity.

The diseases which form the basis of the statements in this article are as follows: leucorrhea, displacements, or malpositions of the internal organs; lacerations, ulcers, tumors, sexual incompetency, and the venereal complications. It is not possible or desirable to tabulate the symptoms which result from these conditions.

An actual description of the life of a patient will be more effective because it will depict the incidental domestic atmosphere in which most of these patients live.
