"Chlorination of Water" by Joseph Race is a scientific publication written in the early 20th century. The book explores the different aspects and methods of water chlorination, a relatively new practice at the time, emphasizing its significance in public health and sanitation. It discusses the historical context, operational procedures, dosage requirements, and the effects of chlorination on various microorganisms.

Joseph Race emphasizes the importance of this sanitary measure, which has been instrumental in advancing public health. He acknowledges the contributions of pioneering figures in the field and outlines the book's intention to consolidate and clarify the scattered information on chlorination practices for better understanding and further research encouragement. The introductory section sets the stage for a detailed discussion of chlorine's chemical properties and its historical applications in water treatment. (This is an automatically generated summary.)
