He recognizes two groups of cases of chronic nephritis: (1) those with efficient cardiac function and adequate peripheral circulation, and (2) those with deficient cardiac function and circulatory stasis. In this latter group, either dilution or concentration of the blood plasma takes place. If the plasma is diluted a relative or dilution anemia occurs.
