PUBLIC HEALTH 449 



health, even what may be learned in this book, should con- 

 sider himself or herself eligible for leadership in matters of 

 public health. There are needed in every community many 

 people who will practise good sanitation and observe all the 

 laws of public health and who will insist that others do the 

 same. What we learn in school should be for use in our daily 

 lives and it is to be hoped that what you have learned here con- 

 cerning health and disease will be made a foundation for your 

 daily practices.
