Abstract
PETRI1 described “kleine gesteilte Kernprominenzen”, small, stalked, deeply staining buds attached to the contorted ring-like nucleus of the mature neutrophil leucocyte of the mouse. La Cour2 showed that they arise from the deeply staining heterochromatic parts of the nucleus, that they are Feulgen-positive and so contain desoxyribose nucleic acid, and are ultimately split off and lie free in the cytoplasm.
