solid in proportion as nine to one.
Therefore, a like proportion should prevail in the total amount of
food taken.
Light exercises an important influence upon the growth and vigor of
animals and plants. Therefore, our dwellings should freely admit the
sun's rays.
Decomposing animal and vegetable substances yield various noxious
gases, which enter the lungs and corrupt the blood. Therefore, all
impurities should be kept away from our abodes, and every precaution
be observed to secure a pure atmosphere.
Warmth is essential to all the bodily functions. Therefore, an equal
bodily temperature should be maintained by exercise, by clothing or by
fire.
Exercise warms, invigorates and purifies the body; clothing preserves
the warmth the body generates; fire imparts warmth externally.
Therefore, to obtain and preserve warmth, exercise and clothing are
preferable to fire.
Fire consumes the oxygen of the air, and produces noxious gases.
Therefore, the air is less pure in the presence of candles, gas or
coal fire, than otherwise, and the deterioration should be repaired by
increased ventilation. The skin is a highly-organized membrane, full
of minute pores, cells, blood-vessels, and nerves; it imbibes moisture
or throws it off according to the state of the atmosphere or the
temperature of the body. It also "breathes," like the lungs (though
less actively). All the internal organs sympathize with the skin.
Therefore, it should be repeatedly cleansed.
Late hours and anxious pursuits exhaust the nervous system and produce
disease and premature death. Therefore, the hours of labor and study
should be short.
Mental and bodily exercise are equally essential to the general health
and happiness. Therefore, labor and study should succeed each other.
Man will live most happily upon simple solids and fluids, of which
a sufficient but temperate quantity should be taken. Therefore,
over-indulgence in strong drinks, tobacco, snuff, opium, and all mere
indulgences, should be avoided.
Sudden alternations of heat and cold are dangerous (especially to the
young and the aged). Therefore, clothing, in quantity and quality,
should be adapted to the alternations of night and day, and of the
seasons. And therefore, also, drinking cold water when the body is
hot, and hot tea and soups when cold are productive of many evils.
Never visit a sick person (especially if the complaint be of a
contagious nature) with an empty stomach, as t
