This volume is intended primarily as a textbook for courses in sanitation for engineers. The various subjects usually treated in a book of this character are discussed. These include water supplies and water purification, disposal of excreta, insect control, plumbing, ventilation, housing, milk sanitation, and control of communicable disease. Descriptions of engineering factors involved in public health problems are adequately handled, but the material involving knowledge of bacteriology and particularly recent applications to public health work is not written in a way to appeal to the public health worker. The section on vital statistics is too brief to be of any value.
