708 In it are discussed the impurities in drinking-water that are oftenest the cause of disease and death, and the natural and artificial processes of removing them. The author's conclusions are the fruit of an experience gained in the analysis and study of nearly a thousand water-supplies, and are aided and re-enforced by the studies and writings of others. A definition of pure water, in a potable rather than a chemical sense, is sought in the first chapter. The inorganic, the vegetable, and the animal constituents of water, micro-organisms, water-supplies, natural and artificial purification, and central filtration, are considered in the several succeeding chapters. Of analysis, only a few elementary qualitative tests are mentioned, the general subject being reserved for another book, which is announced. The language is such as can be easily understood by every intelligent person.
