be an heir of God, an heir of His wisdom, His strength, His
glory, His powers. "All things are yours," says Paul; "life, death,
things present and things to come, all are yours, and ye are Christ's,
and Christ is God's."

CHAPTER XIII.

SPECIAL PHYSIOLOGY.

With a feeling of reverence for ourselves we now take up the subject
of special physiology to learn what makes us women. In the study of
general physiology we find very few physical differences in the sexes,
but when we come to investigate what is called the reproductive system
we find entire difference of structure and of function.

Boys and girls in early childhood are much alike in their
inclinations. They both love activity--to run, to climb, to shout, to
laugh, to play. If left to themselves one sees not much more
difference between boys and girls than between different individuals
of the same sex. But as they grow and develop they begin to take on
characteristics that indicate the evolution of sex.

The boy grows rapidly in height, his voice breaks, the signs of a
moustache appear, he seems constrained and embarrassed in society, and
yet he begins to show more politeness towards women and more of an
inclination to be gallant to girls. He is becoming a man, and assumes
manlike airs. Often, too, he becomes restless and willful, hard to
govern, self-assertive, with an assumption of wisdom that provokes
laughter from his elders. The boy is passing through a serious crisis
and needs much wise and loving care. There are inner forces awakening
that move him strangely; he does not understand himself, neither do
his friends seem to understand him. Sometimes they snub and nag him,
sometimes they tease and make fun of him. In either case he does not
find home a happy place, and frequently leaves it to seek more
sympathetic companionship elsewhere.

I once spoke to an audience of women and girls along this line, and
appealed to the mothers and sisters to be kind to the boys in their
homes who were between twelve and eighteen years of age, to remember
that they were passing through the critical period of transition from
boyhood to manhood, and to try and help them by sympathy and kindness.
Some time later, as I was on the train, a young lady came and sat down
by me and said: "I want to thank you for what you said to us the other
day about boys. I have a brother about sixteen, and we have done just
as you said; we have teased him about his moustache, and his
