Suggestions to mothers are contained in Hugo Salus, _Wo kommen die Kinder her ?_, E.Stiehl, _Eine Mutterpflicht_, and many other books.

Dr.Alfred Kind strongly recommends Ludwig Gurlitt's _Der Verkehr mit meinem Kindern_, more especially in its combination of sexual education with artistic education.

Many similar books are referred to by Bloch, in his _Sexual Life of Our Time_, Ch.

xxvi.
I have enumerated the names of these little books because they are frequently issued in a semi-private manner, and are seldom easy to procure or to hear of.

The propagation of such books seems to be felt to be almost a disgraceful action, only to be performed by stealth.
