Knowledge is Safety.

1. The old maxim, that "Knowledge is power," is a true one, but there is
still a greater truth: "KNOWLEDGE IS SAFETY." Safety amid physical ills
that beset mankind, and safety amid the moral pitfalls that surround so
many young people, is the great crying demand of the age. {4}

2. CRITICISM.--While the aim of this work, though novel and to some extent
is daring, it is chaste, practical and to the point, and will be a boon and
a blessing to thousands who consult its pages. The world is full of
ignorance, and the ignorant will always criticise, because they live to
suffer ills, for they know no better. New light is fast falling upon the
dark corners, and the eyes of many are being opened.

3. RESEARCHES OF SCIENCE.--The researches of science in the past few years
have thrown light on many facts relating to the physiology of man and
woman, and the diseases to which they are subject, and consequently many
reformations have taken place in the treatment and prevention of diseases
peculiar to the sexes.

4. LOCK AND KEY.--Any information bearing upon the diseases of mankind
should not be kept under lock and key. The physician is frequently called
upon to speak in plain language to his patients upon some private and
startling disease contracted on account of ignorance. The better plan,
however, is to so educate and enlighten old and young upon the important
subjects of health, so that the necessity to call a physician may occur
less frequently.

5. PROGRESSION.--A large, respectable, though diminishing class in every
community, maintain that nothing that relates exclusively to either sex
should become the subject of popular medical instruction. But such an
opinion is radically wrong; ignorance is no more the mother of purity than
it is of religion. Enlightenment can never work injustice to him who
investigates.

6. AN EXAMPLE.--The men and women who study and practice medicine are not
the worse, but the better for such knowledge; so it would be to the
community in general if all would be properly instructed on the laws of
health which relate to the sexes.

7. CRIME AND DEGRADATION.--Had every person a sound understanding on th
