464 THE PRACTICE OF VETERINARY MEDICINE. 



The urine may sometimes be somewhat dark in colour, 

 owing to the presence of pigmentary matter. This is symp- 

 tomatic of the existence of melanotic deposits within the 

 bladder. The animal gradually falls off in condition. The 

 bladder is found by an examination per rectum to be in a state 

 of distension, and hanging over the brim of the pelvis, and 

 on being emptied the tumour, etc., may usually be detected 

 by manipulation of the viscus. 



Treatment. — Very little can be done in the way of treat- 

 ment. In case the trouble is caused by the presence of a 

 fungoid growth, the animal should be carefully dieted, and 

 the mineral acids administered. In cases where the growth 

 does not give rise to much inconvenience, it had better be 

 let alone. It is scarcely practicable to cut in and remove 

 such bodies ; still, such an operation might possibly be per- 

 formed with success, and, in cases where it is the only 

 alternative, should be tried ; the after treatment, of course, 

 being that calculated to allay inflammatory action. The 

 diet should be highly nutritious, and properly regulated 

 as to quantity, etc. 



INVERSION OF THE BLADDER. 



Inversion of the bladder is of most frequent occurrence 

 amongst mares and cows, and usually foUow^s difficult partu- 

 rition. 



Symptoms. — A small and reddened tumour-like substance 

 is noticed protruding from the vulva, and is often mistaken 

 for the mucous membrane of the vagina, a mistake which 

 may easily be dissipated by a manual exploration of the 

 parts. The urine escapes, and, dribbling down over the 

 thighs, excoriates the parts, and causes considerable irrita- 

 tion. 



Treatment. — Bathe the displaced organ with warm water
