This is part of an elaborate system covering the entire field of practical medicine. This volume describes diseases of the kidney. Following the usual chapter on renal anatomy and physiology, the pathologic changes are taken up. These are presented for the most part according to the views of Ambard and Widal on renal elimination. In the discussion of the pathology and clinical manifestations of medical kidney diseases, modern views and differentiations are touched on merely in a cursory manner. The inflammatory diseases of the kidney, parasitic derangements and disorders due to tumors are treated in the traditional way. The closing chapter deals with hemoglobinuria.
