Secondly, they must realize that real progress in the science of obstetrics can be expected to proceed only from well equipped clinics connected with strong universities, and in charge of thoroughly trained and broad-minded men. As yet such institutions scarcely exist in this country. Women who are anxious to promote the welfare of their sex can find no better way of doing so than by bringing this need to the attention of wealthy men interested in philanthropy and education. Furthermore, they should bear in mind that most of our important discoveries would not have been made had animal experimentation not been available, as it is solely by this means that modern surgical and obstetrical technique has been brought to its present degree of perfection; and further progress can scarcely be expected without its aid. They should remember also that whenever they take such a well-known drug as ergot for the control of bleeding, or make use of many other apparently simple measures, they are unconsciously rendering tribute to this type of investigation.
