THE SANITARY ENGINEERING PROBLEMS 



OF WATER SUPPLY AND SEWAGE 



DISPOSAL IN NEW YORK CITY" 



The Section on Public Health of the 

 New York Academy of Medicine is formed 

 at a peculiarly opportune time. Never 

 before has sanitary information of a re- 

 liable, authentic character been so much 

 desired by the public, nor so difficult for 

 the public to obtain. 



Our great universities have, for the most 

 part, failed to recognize the vast popular 

 and educational value which would attach 

 to the establishment of adequate facilities 

 for teaching sanitary science, hygiene, 

 public health or preventive medicine, as 

 that body of knowledge which relates to 

 the prevention of disease is variously 

 termed, and have left this kind of teaching 

 largely to the newspapers and to the gen- 

 eral practitioner of medicine. Unfortu- 

 nately, physicians do not always appreciate 

 their importance as sanitary teachers. 



It is in consequence of this that vast 

 stores of scientific facts which are being 

 constantly collected, and which bear upon 

 the causes and ways of preventing disease,
