Epithelia from Urethra (see Fig. 54).—The epithelia from the urethravary considerably in size and shape, being partly flat, partly cuboidal,and partly columnar, and in most cases are comparatively large and ir-regular, so that they can be easily diagnosed. The larger irregular, partlyflat, partly cuboidal epithelia are seen in milder inflammations, such asthe first stages of catarrhal or gonorrhceal inflammations; the irregularcolumnar or cylindrical epithelia occur only in deeply seated inflamma-tions or ulcerations, which often lead to the formation of a stricture.

Thecuboidal epithelia are of exactly the same size as the cuboidal epitheliafrom the ureters, being about twice as large as the pus-corpuscles in everycase, and distinctly larger than those from the convoluted tubules of the8 114 URINARY ANALYSIS AND DIAGNOSIS. kidney. When epithelia of this size are seen in a given case, care mustbe observed to take the relative numbers of these, as well as of those fromthe convoluted tubules and the pelvis of the kidney, into considerationbefore reaching a positive diagnosis. For instance, if they are present inlarge numbers, while those from the kidneys and pelves are entirely ab-
