CYSTITIS. 463 



symptom, a small quantity of urine being passed each time, 

 and in the aggregate a considerable quantity is voided. 

 An examination per rectum will reveal heat, and give rise 

 to pain. The urine may, or may not, be altered in appear- 

 ance. As a rule, the horse stamps, lies down, but rarely 

 rolls in a violent manner, in many cases not rolling at all. 



Treatment. — If the inflammation is very severe, and much 

 fever is present, febrifuges and sedatives, as tr. aconite, 

 may be given with benefit. If the patient be a female, 

 tepid water and opii tr. may be injected into the bladder, 

 and enemas of tepid water may be freely given per rectum. 

 The patient should be warmly clothed, especially in the 

 region of the loins. The animal should also be kept per- 

 fectly quiet, and in some cases a laxative, preferably of oil, 

 may be given with very great benefit. The animal should 

 be encouraged to take demulcent drinks, etc. 



MELANOTIC DEPOSITS IN THE BLADDER. 



Melanotic deposits are occasionally met with in the 

 bladder, particularly amongst grey horses. Tumours and 

 fungoid growths of other kinds are also found in the 

 bladder. In some cases they almost fill it, interfering 

 with its functions to a considerable extent, and causing 

 the bladder to become distended, and the ureters very 

 much enlarged. These conditions may be caused by hard 

 work, and an insufficient supply of nourishment, etc. 

 Melanosis, as above stated, is most frequently found in 

 grey or light-coloured animals, and especially if of advanced 

 age. 



Symptoms. — There is always more or less difficulty in 

 voiding the urine, which at first may be of a natural 

 appearance ; but after awhile blood may be voided with 

 it, in consequence of rupture of a small bloodvessel.
