This volume, which is intended to be a concise and readily understandable manual of methods of bacteriologic examination of water, divides water bacteria into three classes: Those which are found only in pure water, those which are common in sewage and hardly met with in pure water, those which are specially pathogenic to human beings. The preparation of water plates, collection of water for bacteriologic examination, the natural history of the organisms, the relation of quantitative analysis to the question of pollution, etc., are noticed and the different species described, especial attention being given to those of importance. The subject is a difficult one in some respects, the water bacteria being minute and often pleomorphic; yet, so far as we have observed, the author has handled his subject well.
