(See figs. 146 and 147-) These projections consistof amorphous or finely granular fibrine in which leucocytesand a few larger cellular elements, derived from the epithelium,can generally be distinguished. The inflammatory exudationis very loosely attached to the surface of the pericardium, andis readily detached in the process of preparation. (3.) Detachment and proliferation of the epithelium. Thischange, which is well seen in fig. 148, is sometimes difficult tomake out in sections, but cells of various shapes and sizes,which are undoubtedly derived from the epithelium, can.
