    This book is designed to give an account of that kind of Water Analysis whicli is proper for the examination of water intended for domestic use. In giving processes of analysis, we have been careful to prescribe only such operations as are practicable. Especially we have kept in view the necessity of economy in time. The com- plete examination of a sample of water, as set forth iu the following pages—viz., the determination of solid residue, hardness, chlorine, nitrogen as nitrates and nitrites, ammonia, and organic matter—may be all done in the space of six hours, whilst a partial examination takes a very short time. In thus economising time, we do not think that we have made any sacrifice of accuracy. The process for determining nitrogenous organic matter, termed by us the ammonia-method, and proposed by Mr Miles H. Smith, and ourselves, at a meeting of the Chemical Society last year, occupies a prominent place in this work. A section of Chapter V.* is devoted to a * Chapter VIII. of present edition.
