 The relation of the biology of to-day to health cannot be over- 

 emphasized. One of the reasons why the people of yesterday 

 had so many fears concerning disease was that they were ignorant 

 of methods for preventing and controlling it. The prevention and

 of this health education. The general public understands what 

 the health authorities are trying to accomplish. Because it knows 

 that certain restrictions are formulated in the interests of health, 

 the public readily accepts and carries them out. For example, 

 there is not as much opposition to the Schick test and the sub- 

 sequent immunization for diphtheria, as formerly, because the 

 public has been intelligently instructed concerning the need of 

 this scientific procedure to combat the disease.
