NOTE.--Every thoughtful woman is urged to buy and study carefully the
great work entitled: "PREVENTION OF VENEREAL DISEASE," by Sir Archdall
Reid, K.B.E., M.B., C.M., F.R.S.E., with an introductory chapter by Sir
Bryan Donkin, M.D., F.R.C.P., in order that she may understand the nature
of the problems involved and the strength of the opposition to
_cleanliness_.

_This book is endorsed by the Society for the Prevention of Venereal
Disease and contains the evidence and arguments on which the Society bases
its policy, and is addressed to all who would prevent venereal diseases in
themselves or in the community._

Children may be taught any system of morals--sexual or other; Christian,
Mahomedan, Hindoo, Papuan, or other. They are intensely imitative and
acquire a bias towards local ideas of right and wrong through association
with intimate companions. A bias once acquired tends to persist. For that
reason parents choose good companions and schools. On the other hand, it
is difficult or impossible to convert "hardened sinners," for example,
adult non-Christians. Children, therefore, may be really taught; adults,
as a rule, can only be preached at. Any man may test the truth of all this
by examining his own consciousness. Would any amount of preaching cause
him to change his present ideas of right and wrong? As little can he alter
the bias of other men. As the twig is bent so the tree grows.

In various times and places, almost everything from promiscuous sexual
intercourse to absolute abstinence from all intercourse has been held
holy, or permissible, or damnable. Even among Christians the widest
differences have prevailed as regards the local and contemporary tone.
Among them, especially among the English speaking peoples, a convention
forbids the familiar discussion of sexual matters between children and
adults. This convention may be right or wrong. In any case it exists, and
is likely to persist for ages. But a knowledge of sex is tradition
