The Bacteriological Examination Of Water Supplies Classic Reprint

Excerpt from The Bacteriological Examination of Water-Supplies The writing of a book upon the bacteriological examination of water presents numerous difficulties. Many of the facts upon which such an examination rests have been so recently ascertained, that their value is not readily to be appraised, and difficulty is experienced in selecting those essential and important. My intention has been to demonstrate the facts which are now established, and to bring the varied data into some sort of ordered relationship. Dogmatic opinion has been avoided, the subject being considered from a critical standpoint, and practical conclusions drawn only when they seem justified by the available evidence. Unfortunately, many of the data upon which the bacteriological examination of water is based have net passed beyond the regions of controversy, and on not a few questions - some of which are of much importance - each bacteriologist is, at present, a law unto himself. For certain parts of the subject it has, therefore, not been possible to present any one view as the united and accepted opinion of those whose knowledge entitles them to sit in judgment.
