Diseases of the Urinary System. 209 
the glans penis is swollen, extruded, and mostly erect, a 
small quantity of pustular fluid oozing from the opening. 
Pain is evident in urination, and the animal constantly 
licks the exposed member. In other forms of the dis- 
ease the prepuce is swollen and covers the glans penis, 
retaining the discharge to the further detriment of the 
organ, but allowing a portion to escape and accumulate 
in drying on the hairs around the orifice. By external 
pressure, which the animal stoutly resists, a large quantity 
of discharge may be obtained, sometimes having a dis- 
agreeable odour; and not uncommonly the diseased 
parts are invaded by abscesses and sinuses to a serious 
extent. 
Treatment.—After a thorough cleansing, the long hairs 
should be removed to avoid the accumulation of-dis- 
charge and dirt, the dog should be immersed in a warm 
bath, or fomentations may be locally applied. In either 
case care must be exercised in order to dry the patient 
and prevent his taking cold. Astringent lotions are then 
needed, or the ‘“ Sanitas” mixtures (see Antiseptics) will 
be highly beneficial. The bowels should be moved by 
the castor-oil mixture, and tonics, combined with muci- 
laginous fluids, are essential. 
Parasitic Invasion of the Urethra is on fecord. 
In an instance falling beneath the notice of M. Séon, the 
worm was believed to be the male Eustrongylus gigas, 
upwards of four inches long, and was detected during an 
attack of -urethral irritation and paroxysmal retention of 
urine, occupying the entire length of the urethra. Removal 
of the parasite afforded instant relief.
