Some years ago (in 1900), when it was proposed to deliver a series of lectures on sexual hygiene to the advanced pupils in Berlin schools, under the auspices of a society for the improvement of morals, the municipal authorities withdrew their permission to use the classrooms, on the ground that "such lectures would be extremely dangerous to the moral sense of an audience of the young." The same objection has been made by municipal officials in France.

In Germany, at all events, however, opinion is rapidly growing more enlightened.

In England little or no progress has yet been made, but in America steps are being taken in this direction, as by the Chicago Society for Social Hygiene.

It must, indeed, be said that those who oppose the sexual enlightenment of youth in large cities are directly allying themselves, whether or not they know it, with the influences that make for vice and immorality.
Such lectures are also given to girls on leaving school, not only girls of the well-to-do, but also those of the poor class, who need them fully as much, and in some respects more.

Thus Dr.A.
Heidenhain has published a lecture (_Sexuelle Belehrung der aus den Volksschule entlassenen Maedchen_, 1907), accompanied by anatomical tables, which he has delivered to girls about to leave school, and which is intended to be put into their hands at this time.
