Previous owner's blindstamp on title page; contents otherwise clean and unmarked. Excerpt: "This book contains the information which the average health officer must have in order to discharge his duties. It tells the health officer what to do, how to do it, and why he should do it. It describes the various activities in which a health officer engages; his relation to boards of health, physicians, social agencies, and the public; his qualifications and methods of work; the various diseases and unsanitary conditions with which he deals; and the scientific principles on which the specialty of preventive medicine is founded. It is the result of the years of experience of the authors in public health work, both in rural communities and in New York City, and as supervisors of health officers under the New York State Department of Health. While the book is designed primarily for health officers, its simple language and untechnical form will commend it to college students, public health nurses, members of boards of health, social workers, teachers, and others who are interested in public health work."
