Their number,however, is scanty. Occasionally normal ui-ine contains:large numbers of round epithelia that are derived fromthe prepuce in men or the meatus urinarius or the vaginain women. If such epithelia are present iu very largenumber, this finding usually denotes catarrh of theseparts. It is a very difficult matter to differentiate theepithelia of the kidneys, the pelvis, ureters, bladder, andurethra. As a rule, although not always, renal epitheliaarc smaller than the epithelia from lower portions of the.

In some cases the spermatozoa are are about 50 // long, the head usually being from4 to 5 u in length. Spermatozoa are found after coitus or emissions (epi-leptic seizures, nocturnal pollutions, etc.) in male urine,and may also occasionally be found in the first urinevoided by women after coition.
