THE AMOUNT OF SLEEP. The amount of sleep required varies with the age,
habits, condition, and peculiarities of the individual. No definite rule
can be given for the guidance of all. The average amount required,
however, is eight or nine hours out of the twenty-four. Some persons
need more than this, while others can do with less. Since both body and
mind are recuperated by sleep, the more they are exhausted the more
sleep is required. A person employed at mental labor should have more
than one who is merely expending muscular strength. Six hours of
unbroken sleep do more to refresh and revive than ten when frequently
interrupted. If it is too prolonged it weakens and stupefies both body
and mind. If an insufficient amount is taken the flagging energies are
not restored. Persons who eat much, or use stimulants generally require
more than others. To sleep regularity is desirable. If a person goes to
bed at a certain hour for several nights in succession, it will soon
become a habit. The same holds true with regard to rising. If children
are put to sleep at a stated hour for several days in succession, it
will soon become a habit with them.

CLEANLINESS.

"Cleanliness is next to godliness," and is essential to the health and
vigor of the system. Its importance cannot be overestimated, and it
should be inculcated early on the minds of the young. "Even from the
body's purity, the mind receives a secret sympathetic aid."

When we consider the functions of the skin, with its myriads of minute
glands, innumerable little tubes, employed in removing the worn-out,
useless matter from the system, we cannot fail to appreciate the utility
of frequent bathing with soap and water. Unless these excretions are
removed, the glands become obstructed, their functions are arrested, and
unpleasant odors arise. Many persons think because they daily bathe the
face, neck, and hands, dress the hair becomingly and remove the dirt
from their clothing that the height of cleanliness has been reached.
From a hygienic point of view, bathing the _entire_ body is of much
greater importance.

Notwithstanding the necessity for cleanliness of the body, we
occasionally meet with persons who, although particular about their
personal appearance, permit their bodies to be for weeks and even months
without a bath. Such neglect should never exceed one week. Plenty of
sunlight and at least one or two general baths every week are
