This seventh edition presents a new departure in that the methods applicable in each disease with the usual findings are collected in a separate part of the work, so that the physician may compare the findings in any particular case with the clinical laboratory picture of the disease suspected. The names of diseases are arranged alphabetically. The book has been thoroughly revised. The Wassermann reaction and the Noguchi modification are fully described. In every department the work seems to have been brought fully up to date and its excellence will sustain the reputation which this manual has already achieved. The book is finely illustrated, colored plates being used to a large extent.
