Advances in the treatment of Addison's anemia in the last few years are so full of promise that it is now of more importance than ever to make an early and decided diagnosis of this disease. If the full benefits of the newer treatment1 are to be obtained, the diagnosis should be made at least early in the first period of anemia. Indeed, in some cases it is possible to make the diagnosis so early, even before the anemia is apparent, that it may not be in vain to hope that at times the disease as we now know it may be entirely prevented.
It is to aid in the more exact differentiation of the anemias that this work is presented, for it is believed that careful measurement of the red blood cells helps materially in such differentiation. This thesis was presented originally by Price-Jones in England,2 was later enlarged
