About This Book

The text presents principles of hygiene and sanitation interpreted through chiropractic philosophy, defining personal and public hygiene and emphasizing both environmental measures and internal resistance to disease. It surveys practical topics — housing, air and ventilation, heating and lighting, water, school and industrial hygiene, immunity, germs, disinfection, sick-room care, and food and milk safety — arranged as a sanitary handbook. A second section addresses pediatric care, covering infant management, dentition, clinical analysis, techniques for adjusting children, and common respiratory, digestive and miscellaneous conditions. Instructional in tone, the work combines sanitary science with applied chiropractic technique for prevention and child-health care.
