and the liquids forced in and drawn out by its aid. 
(N.B.—Of course, the bladder is emptied before any 
solution is introduced into it.) 
If there is much hematuria a 2 per cent. solution of 
tannic acid may be injected. Internally one should 
administer salol (grs. ii. to grs. x.), salicylic acid (grs. iil. 
to grs. x.), urotropine (grs. v. to grs. xv.), pot. nitrate 
(grs. vi. to grs. xx.), benzoic acid (grs. iil. to grs. X.), 
copaiba (mx. to 3i.), or infusion of buchu (ss. to ii.) with 
oleaginous laxatives. 
Salol and urotropine are particularly useful, and I pre- 
scribe them four or five times daily in every case of 
bladder implication, especially when accompanied by 
pain. It may be mentioned in passing that urotropine is 
the proprietary name for hexamethylene, and if pur- 
chased under the latter name is considerably cheaper. 
Glass recommends morphine or bromide of soda in 
cases where there is involuntary or constant urination. 
If the condition is acute, hot poultices or Priessnitz 
compresses may be applied over the region of the 
bladder. 
Urino-Genital Organs.—The catarrhal or purulent 
discharges emanating in rare instances from the vagina 
of bitches and penis of dogs, are usually soon checked 
by injections of antiseptic solutions, the best of which 
are corrosive sublimate (1 to 4,000), zinc sulphate 1 per 
cent., and permanganate of potash 1 per cent. 
Otitis.—Before any therapeutic agent can be used, the 
ear must be thoroughly cleaned out, for it will be found 
to contain brownish crusts and an offensive waxy or 
purulent discharge, which must all be removed by means 
of cotton-wool attached to the end of a pair of fine 
spring forceps. Dipping the wool in spirit, such as 
ether, methylated spirit, or chloroform, aids greatly in 
dissolving the ear discharges, and after their complete
