Not unfrequentlythe cells in such a patch take on the wavy border described aboveas met with in the lymphatics of origin (see the isolated patchesin fig. 197). Further, the flattened cells which form the walls ofthe lymphatics are connected here and there both with the moreramified cells of the tissue (fig. 199, e) and with those which form 306 LYMPHATIC SYSTEM. the epithelioid patches, and in silvered preparations they appear to becontinuous with one another. The epithelioid patches look in fact likea part of the lymphatic vessels,
