AN INTRODUCTION TO THE
PHYSIOLOGY AND PSYCHOLOGY OF SEX

49 Illustrations. Large Crown 8vo. Cloth. 7s.6d. net (by post, 8s. 1d.).

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._

SEX LORE. A Primer on Courtship, Marriage and Parenthood.
55 Illustrations. Crown 8vo. Cloth, 7s. 6d. net (by post, 8s. 1d.).

"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._
