The Schilling blood count varies from the usual differential count in the division of the polymorphonuclear neutrophils into groups according to the degree of their maturity. These cells are counted separately and tabulated to form a "hemogram." Repeated at frequent intervals in a given case and set up in vertical columns, the successive blood counts combine to form a comprehensive picture, more valuable than the ordinary count in the interpretation of an illness. When a curve of the repeated counts is plotted against the fever chart, the progress of an infection is shown graphically.
The Schilling count has been used abroad in adults (for a complete bibliography see Schilling-Gradwohl1). Several observers have given normal blood figures for infants and children, and there are sporadic reports of isolated cases. Complete investigations, however, have not been made in this field.
It is planned to continue these counts in a series of
