The epithelial covering of the genito-urinarymucous membrane is, like the external skin, constantlyexperiencing the effects of wear and tear, causing amore or less rapid exfoliation of epithelial cells. Thisstructure is sometimes partly broken up so as to appearlike patches of membrane-like mucus, and its cells areirregularly lacerated. Most generally, however, a certainnumber are entire, and can be readily recognised bytheir microscopic characters ; when distended with fluid EPITHELIUM. 357. they are regularly oval cells,becoming irregularly angularand flattened when partiallyempty. When they are quiteempty a well-marked centralnucleus, often appearing, ifthe focus be not properly ad-justed, to project like the cen-tral boss of a shield (Fig. 56),Flg 56 is seen in each. These cells sometimes contain fat globules, and when existing inany quantity, have been stated to be pathognomonic ofsome varieties of morbus Brightii (369). The exfolia-tion of epithelium sometimes is very considerable, soas to give rise to a copious deposit in the urine whichto the naked eye resembles mucus ; but may be readilydistinguished by the absence of all viscid with liquor potassse, such urine gelatinisesnearly as perfectly as when pus is present. When ox-alate of lime exists in the urine, an abundance of epi-thelium is generally found, and indeed has often, fromits presence, induced me to make a caref
