ventilated, and the air maintained at a equable temperature of as near
60° Fahr. as possible. An inability to sleep at the proper time, or a
regular inclination to sleep at other than the natural hours for it, is
a certain indication of errors of habit, or of nervous derangement.

10. Prominent among all other measures for the maintenance of Health, is
personal cleanliness. Activity in the functions of the skin is essential
to perfect health, and this can only be secured by thoroughly bathing
the entire body. Strictly, a person should bathe once every twenty-four
or forty-eight hours. The body should be habituated to contact with cold
water at all season of the year, so that warm water may not become a
necessity. The simplest and most convenient bath, is the ordinary
sponge-bath. An occasional hot-air, or Turkish bath, exerts a very
beneficial influence. It cleans out the pores of the skin and increases
its activity.

11. The emotions and the passions exert a powerful influence over the
physical organism. It is important, therefore, that they be held under
restraint by the reasoning faculties. This rule applies equally to joy,
fear, and grief; to avarice, anger, and hatred; and, above all, to the
sexual passion. They are a prolific source of disease of the nervous
system, and have caused the dethronement of some of the most gifted
intellects.
