Without going into detail concerning these things, the writer states that it is a matter of common knowledge among physicians that in every large city there are thousands of unscrupulous (including those who call themselves physicians) who are kept busy every week in the year performing criminal operations designed to produce abortions. Some of these practitioners have many regular patients--women who visit them regularly for the purpose of having abortions produced by criminal operations. It seems almost incredible, but it is a veritable fact, that there are to be found many women in the large cities who actually boast to their friends of the number of operations of this kind they have had performed on them. Surely, any instruction which would prevent the physical breakdown of so many women by reason of excessive child-bearing on the one hand, and abortion on the other hand, would seem to be worthy of the hearty support of society, and the encouragement of its laws, rather than the reverse. So true does this seem, that it is difficult to realize that there are any intelligent persons who would condemn such instruction as evil and harmful to society. That such persons do exist is a striking proof of the persistence of ancient superstitions and the survival and tenacity of old prejudices. MORALITY OF MARRIED MEN. It is a matter of common knowledge among physicians, and students of sociology, that many married men, particularly those living in the large cities, indulge in extra-marital or illicit sexual relations, with prostitutes and other women of loose morals, and this not because these men are naturally vicious, depraved or licentious, but rather because they fear causing their wives to bear them more children--the wives either being in delicate or broken-down health, or else the family already too large to be reared properly in justice to the children. Many persons who would see only what "ought to be," and who refuse to see "things as they are" in modern society, will be disposed to pooh-pooh the above statement, and to accuse those making it to be sensational or even morbid on the subject. But those who are brought in close contact with men and women, as are family physicians and specialists, as well as honest students of sociology, know only too well that the above is not an over-statement, but is rather a very conservative recital of certain unpleasant, but true, facts of human society.
