“…Weil (1936) and Moeschlin (1947), in their monographs, gave detailed descriptions of the " splenogram " in various haematological conditions. Only occasional reports of the procedure appeared in the American literature until recently, when Block and Jacobson (1950) and Morrison et al (1951) described their experiences. Only a few authors like Heilmeyer (1942), Ferrata and Storti (1946), Weil (1949), and Wintrobe (1951) stress the diagnostic value of splenic puncture in their text6ooks of haematology.…”
