Abstract
THE first of these two volumes is described as “a practical treatise of the examination of sewage and effluents from sewage.” Many practical hints on the analysis and treatment of sewage are given; and the collection of original papers printed as an appendix contains useful notes and explanations on various analytical processes in chemistry. The object of the book is, however, stated to be to bring about a reformation in the analysis of sewage, and to point the way to its proper disposal. Apparently one of the chief reforms required, according to Mr. Wanklyn, is to induce chemists using the ammonia process of water analysis to express the readings of albuminoid ammonia in terms of parts per million, instead of parts per 100,000 and grains per gallon. But other reforms are urged; and as Mr. Wanklyn claims that “In some respects the opportunities enjoyed by my colleague and myself are absolutely unique,” and remarks that “the severance of all relations with the London Chemical Society has operated to our advantage,” the volume evidently contains criticisms and conclusions upon which a difference of opinion may be permitted.
