These shreds are composedof pus, a little blood, and a number ofround or oval and occasionally caudatecells caught together in a mucous ve-hicle (Fig. 9). The prostatic cells areoften found in pathological conditionswhere they are associated with pros-tatic fluid, and can sometimes be local-ized by this means. Cells from the anterior urethra areof little diagnostic importance, as the discharge at the meatus, together withthe endoscope, serves much better for diagnostic purposes. It is evident that the cell-characteristics of one area of membrane veryoften merge so gradually into those of the neighboring regions that accuratelines of demarcation are impossible. None but the experienced observer can3.

Pus.—Pus is so common a constituent of urinary sediments that itscareful study is of the utmost importance, for its very prevalence is apt tomake the observer careless and to belittle the part it plays in urinary diag-nosis. Pus-corpuscles are about the size of renal epithelium, but have avery distinct outline, and usually more than one nucleus, the most commonnumber being three. The corpuscles have a granular appearance, and if theinflammation has lasted for some time, they lose their distinct outline andtheir nuclei become less distinct and
