Cleanliness and health (second edition).

This film shows through photomicography how germs multiply if provided with food, warmth and moisture and illustrates measures we can take to prevent infections. We learn that germicides in certain soaps keep some germs from spreading and the methods of cleanliness in a hospital that help maintain good health there. Similar methods of cleanliness - with clothing, skin, hair nails and teeth - help preserve our own health.
