Abstract
THE fact that a second edition has been called for only two years after the issue of the first, shows that this excellent hand-hook has been very generally appreciated. The authors have revised the work and made many additions to it chiefly of processes that have recently grown in importance. Among the principal of these additions, we observe that the three pages on “Living Organisms in Water” of the first edition are now expanded into a chapter of thirteen pages entitled, “Biological Examinations”, A table of culture phenomena of some of the more important microbes is given. But concerning this matter the authors state that “until pathogenic microbes are more clearly indicated and described, the methods will be of little use in dealing with the problem of the determination of the sanitary and technical value of water supplies.”
