title: [Blood groups and disease].
abstract: The inquiry for the sense of blood group polymorphisms (enzyme groups and serum groups included) and their significance for the constitution and also disposition to diseases is for the time being absolutely legitimate. But it is shown that the field--scarcely a new hereditary blood factor has been detected--becomes a subject of speculations, possibly of the teleological kind: "For which purpose is the factor existing?", or even "Why has God made up the factor?". The hypotheses developing on that are often extremely suggestive and incorrect hypotheses on the first opportunity sometimes reappear like a "cork-tumbler". Finally only a few hard facts remain. This is shown with the help of the systems AB0, Duffy, HLA, Hp and Pi.
