WITH THE COLLABORATION OF 25 DISTINGUISHED SPECIALISTS All interested in aquatic biolog}' will find here answers to their queries on methods of study, conditions of existence, types of life, and inter-relations of the organisms that inhabit our fresh-water l^odies, together with data on their life histories, habits and range. This work is the first complete and accurate record of North American aquatic life, especially the micro-organisms among both plants and animals excluding" the vertebrates, higher plants and bacteria, every form is described that has been reported from a fresh-water body on this continent. comprehensive general discussion of each group precedes the description of individual forms, which are arranged under a key to permit of rapid and accurate determination of the genera and species. Nearly every form is illustrated, and its diagnostic features are pointed IHological data on its habits, frequence and distribution are also out. ;
