What is this waste called when it comes from the surface of the
skin?--"Perspiration."

When does the perspiration flow through the pores of the skin?--"All the
time, if the skin is healthy."

Why do we not always see the perspiration which passes through the
pores?--"Because it does not always form drops on the surface of the skin;
it generally passes off in very fine particles."

What becomes of the fine or minute portions of perspiration which pass from
the body?--"Some of these portions are absorbed by the clothing; some pass
into and mix with the air around us."

What effect does the perspiration produce on the air and the clothing?--"It
soon makes the air unfit to be breathed, and the clothing unfit to be
worn."

What is necessary if you would have a healthy skin? [See Formula.]

Why must you wear clean clothing?--"That there may be nothing impure in the
clothing for the pores of the skin to absorb."

Why should you breathe pure air?--"Because air purifies the blood, and pure
blood is necessary to make a healthy skin."

How does drinking alcoholic liquors hurt the skin?--"It makes the blood
impure, and impure blood makes unhealthy skin."
