There are three diseases of early childhood, apparently rather closely related not only in symptomatology but probably also in fundamental etiology, which to my mind are of peculiar interest because of the opportunity which they seem to offer for the solution of some of the intriguing problems presented by the hemolytic anemias, which now interest many in the medical profession.
These three diseases are: congenital hemolytic icterus, sickle-cell anemia and the disease which I have attempted to define in a previous paper1 and which has hitherto been included under the rather vague classification of von Jaksch's anemia. In my paper on this subject, for reasons there given, I suggested leaving it under that title, in spite of the fact that I did not believe it to be the disease which von Jaksch was describing, if indeed he had in mind anything which would now be considered a clinical entity.
