though it may be briefly treated.

The amount of sleep that each individual requires and should take can
only be determined by the individual. Some seem to require ten hours,
others eight, others six, while rarely individuals are found who seem
to thrive on even so little as five hours of sleep out of twenty-four.
The average requirement seems to be about eight hours. If one has by
experience or experiment determined the amount of sleep which he
requires, he should so plan his daily regime that he can secure that
amount of sleep. While a brief departure from this regime may be
without serious results, any prolonged departure from it will
certainly bring its natural retribution. So, the young man having
determined how much sleep he needs, should adopt a daily program that
will provide for just that many hours in bed, and he should early
establish the habit of going to sleep at once upon retiring, and of
arising at once upon awakening. Dallying in bed has led many a young
man to lapse into habits of thought and of action that are in a high
degree deleterious, morally and physically.

So far as one may choose the equipment of his sleeping apartment, he
should choose a hard bed and a cover as light as possible and yet be
comfortable.

One should never retire with cold feet. A most effective way to warm
the feet is to dip them for a moment in cold water and then rub them
vigorously with a coarse towel until they glow with warmth.
Furthermore, no more effective remedy for habitual cold feet could be
devised than this nightly tonic bath.

One will add greatly to his comfort and decrease largely the danger of
taking cold if he provides himself with a pair of warm bed room
slippers, which should always be worn during one's excursions to the
bath room, and during his tonic sponge bath.

As to posture in bed, the experience of men in general is, that the
most comfortable posture and the most hygienic one is to lie upon the
side. The right side is to be preferred to the left because in this
position, the heart being on the upper side, is not embarrassed in its
free movement by the superincumbent lung tissue. Furthermore, this
position facilitates the passage of digesting foods from the stomach.
To maintain comfortably this side position, requires that the knees
be at least moderately drawn up. This posture when asleep is
practically identical with that of nearly all higher animals, and is
unquestionably the most
