It may be added that medical opinion has long approved of this enlightenment.

Thus in England it was editorially stated in the _British Medical Journal_ some years ago (June 9, 1894): "Most medical men of an age to beget confidence in such affairs will be able to recall instances in which an ignorance, which would have been ludicrous if it had not been so sad, has been displayed on matters regarding which every woman entering on married life ought to have been accurately informed.

There can, we think, be little doubt that much unhappiness and a great deal of illness would be prevented if young people of both sexes possessed a little accurate knowledge regarding the sexual relations, and were well impressed with the profound importance of selecting healthy mates.

Knowledge need not necessarily be nasty, but even if it were, it certainly is not comparable in that respect with the imaginings of ignorance." In America, also, where at an annual meeting of the American Medical Association, Dr.Denslow Lewis, of Chicago, eloquently urged the need of teaching sexual hygiene to youths and girls, all the subsequent nine speakers, some of them physicians of worldwide fame, expressed their essential agreement (_Medico-Legal Journal_, June-Sept., 1903).
Howard, again, at the end of his elaborate _History of Matrimonial Institutions_ (vol.iii, p.

257) asserts the necessity for education in matters of sex, as going to the root of the marriage problem.
