Principles of Sanitary Science and the 

 Public Health 



With Special Reference to the Causation and Prevention of 

 Infectious Diseases 



BY WILLIAM G. SEDGWICK, PH.D. New York 



868 pp., 8vo, $3.00 



The direct outgrowth of a course of lectures given for 

 several years by the author to his students. 



The author prefers to deal as far as possible at first hand 

 with matters within his own knowledge rather than to de- 

 pend upon the digests or even the original reports of others. 



Discusses the principles rather than the arts of sanitation. 



Well adapted for text or reference use in courses on hy- 

 giene and sanitation.
