alcohol, and yet he is more likely to have consumption than he would
have been if he had been a total abstainer. "Drunkard's consumption" is
one of the most dreadful forms of this disease.


SUMMARY.

1. Pure air is as necessary as food and drink.

2. Anything which is rotting or undergoing decay causes a bad odor, and
thus makes the air impure.

3. Foul air contains germs which cause disease and often death.

4. Persons sick with "catching" diseases should be carefully avoided.
Such persons should be shut away from those who are well, and their
rooms and clothing should be carefully cleansed and disinfected.

5. The breath poisons the air about us. Each breath spoils half a
barrelful of air.

6. We should change the air in our houses, or ventilate them, so that we
may always have pure air.

7. We should always keep the body erect, and expand the lungs well in
breathing.

8. The clothing about the chest and waist should be loose, so that the
lungs may have room to expand.
