There is no evidence that in England the Minister of Education has yet taken any steps to insure the delivery of lectures on sexual hygiene to the pupils who are about to leave school. In Prussia, however, the Ministry of Education has taken an active interest in this matter, and such lectures are beginning to be commonly delivered, though attendance at them is not usually obligatory. 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 Mädchen_, 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. Salvat, in a Lyons thesis (_La Dépopulation de la France_, 1903), insists that the hygiene of pregnancy and the care of infants should form part of the subject of such lectures. These subjects might well be left, however, to a somewhat later period.
