od physical education, and even then the
probabilities are that they will find life a burden hardly worth
living.

5. NO REAL BLESSING.--Where one parent is consumptive and the other
vigorous, the chances are just half as great. If there is a scrofulous
or consumptive taint in the blood, beware! Sickly children are no
comfort to their parents, no real blessing. If such people marry, they
had better, in most cases, avoid parentage.

6. WELFARE OF MANKIND.--The advancement of the welfare of mankind is a
most intricate problem: all ought to refrain from marriage who cannot
avoid abject poverty for their children; for poverty is not only a
great evil, but tends to its own increase by leading to recklessness
in marriage. On the other hand, as Mr. Galton has remarked, if the
prudent avoid marriage, while the reckless marry, the inferior members
will tend to supplant the better members of society.

7. PREVENTIVES.--Remember that the thousands of preventives which
are advertised in papers, private circulars, etc., are not only
inefficient, unreliable and worthless, but positively dangerous, and
the annual mortality of females in this country from this cause alone
is truly horrifying. Study nature, and nature's laws alone will guide
you safely in the path of health and happiness.

8. NATURE'S REMEDY.--Nature in her wise economy has prepared for
overproduction, for during the period of pregnancy and nursing, and
also most of the last half of each menstrual month, woman is naturally
sterile; but this condition may become irregular and uncertain on
account of stimulating drinks or immoral excesses.

THE GENERATIVE ORGANS.

[Illustration: THE MALE GENERATIVE ORGANS AND THEIR STRUCTURE AND
ADAPTATION.]

1. The reproductive organs in man are the penis and testicles and
their appendages.

2. The penis deposits the seminal life germ of the male. It is
designed to fulfill the seed planting mission of human life.

3. In the accompanying illustration all the parts are named.

4. URETHRA.--The urethra performs the important mission of emptying
the bladder, and is rendered very much larger by the passion, and the
semen is propelled along through it by little layers of muscles on
each side meeting above and below. It is this canal that is inflamed
by the disease known as gonorrhoea.

5. PROSTATE GLAND.--The prostate gland is located just before the
bladder. It swells in men who hav
