1. Yeast is composed of living plants which begin the work 



of returning sugar back to its original elements. 



2. Mold is composed of tiny rodlike plants which grow 



through animal and vegetable tissues and destroy 

 their albumin. 



3. Bacteria are the smallest living beings. They cause 



decay and change albumin back to its elements in 

 the air and soil. 



4. Bacteria may produce virulent poisons. 



,5. A few kinds of bacteria grow* in the body and there 

 produce various forms of disease, some of which 

 can be transmitted to other persons.

by the white blood cells, by the plasma, and by sub- 

 stances produced in the blood. 



7. Outside of the body, sunlight, fresh air, running water, 



and the soil destroy disease germs. 



8. Man destroys disease germs by washing them away, 



by boiling objects containing them, and by poison- 

 ing them with such substances as carbolic acid and

every sick room, and especially in infectious diseases.
