RULES FOR THE PRESERVATION OF HEALTH.

Pure atmospheric air is composed of nitrogen, oxygen and a very small proportion of carbonic acid gas.  Air once breathed has lost the chief part of its oxygen, and acquired a proportionate increase of carbonic acid gas.  Therefore, health requires that we breathe the same air once only.

The solid part of our bodies is continually wasting and requires to be repaired by fresh substances.  Therefore, food, which is to repair the loss, should be taken with due regard to the exercise and waste of the body.

The fluid part of our bodies also wastes constantly; there is but one fluid in animals, which is water.  Therefore, water only is necessary, and no artifice can produce a better drink.

The fluid of our bodies is to the 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.
