This fills a gap in the literature of sex. It gathers together for the general reader a vast array of facts about sex, mating and reproduction which have never before been so clearly and directly stated.

"For a simple statement, expressed in language as far as possible free from technicalities, of the principal phenomena of generation, Dr. Herbert's book is the best that we have seen."—Cambridge Review.

"It is therefore a real satisfaction to find a sex manual which may be placed with confidence in the hands of any educated person.... He has certainly produced the best little manual which we yet possess in this field."—HAVELOCK ELLIS in Eugenics Review.

"The author in simple, non-technical language expounds the main facts of sex, especially with regard to biology and physiology, and she treats this delicate subject in a tactful manner. A special feature of the book is the large number of illustrations. The volume is intended for the 'younger generation,' but parents and teachers would be well advised to peruse the book, which should prove invaluable for educative purposes. '—Medical Times.

"... may be left with confidence in the hands of any educated person who is attaining to manhood or womanhood."—Aberdeen Daily Journal.
