INFLAMMATION OF THE KIDNEYS. 53 



exudation on its surface and in its substance ; the structure 

 is easily broken down, and sometimes an abscess is found. 



Treatment. The intestine must be cleared out as much 

 as possible, and rather frequently, by means of simple warm 

 water injections. Linseed tea or other emulsions should be 

 given with liberal doses of acetate of ammonia. In dogs, 

 small doses of the potassio-tartrate of antimony are very 

 useful. In the horse, it may be advisable to give a dose of 

 aloes, but it is best to avoid all active remedies that require to 

 be given in large doses. Warm fomentations to the loins, 

 mustard poultices, or a hot sheep skin, afford great relief. If 

 the pain continues, considerable doses of camphor and opium 

 are called for. 



ABSCESS AND FISTULA. 



D'Arboval mentions an interesting case of this disease, 

 which Mr Percivall has rendered in his work on " Hippo- 

 pathology," in the following terms : 



" A mare fell into a hole, out of which she was got with 

 great difficulty. From that moment she experienced incon- 

 venience in locomotion. The vertebral column appeared in- 

 flexible, the pulse tense and irregular, the urine scanty, thick, 

 and sometimes mingled with streaks of blood. The mare lay 

 down but little, not being able to raise herself up again, with- 

 out great pain. M. Chouard being called to her, perceived 

 at the superior part of the right flank a considerable swell- 

 ing which had been there some time, and had continued 

 to augment from day to day without any sign of inflamma- 

 tion. At the end of a month he opened the tumour, and let 

 out a prodigious quantity of pus. The puncture cicatrised ; 

 but in six months' time a deep fistula had formed in it, 

 which, every time the horse moved, ejected a stream the size 

 of the finger of white grumous pus. Notwithstanding it was 

 twice laid open, the fistula would not heal, and the horse
