In the serous form whichusually occurs at the commencement of the pericarditis the pericardialfluid is increased in quantity, and rendered turbid by the presenceof migrated leucocytes, cast-off endothelial cells, and bacteria. Lateron, however, there ensues a continually increasing exudation of fibrin,or an emigration of white corpuscles, in consequence of which theexudation becomes either more fibrinous or more purulent respectively. Under the microscope (Fig. 101) the pericardium is seen even.
