As a rule, the flat portion appears more extensiA^e in surfaceview than the nucleated portion, but in exceptional cases theformer covers the capillaries only partially and is consequentlysmaller than the latter. Occasionally the flat portion stretchesout over the capillaries and reaches the neighboring intercapillaryspace. In rare cases a small intercapillary space may have nonucleated portion and is covered only by the flat portion. When THE AMERICAN JOURNAL OF ANATOMY, VOL. 27, NO. 3.
