338 BOVINE PATHOLOGY. 



considerably increased fever, urinous sweats, foetid evacu- 

 ations of faeces, and paralysis. In some cases the 

 diagnosis of this disorder will be found very difficult. 



On post-mortem examination, one or both kidneys are 

 found disorganised, enlarged, and reddened. Lymphy 

 deposits occur in parts of the organ, and sometimes sup- 

 purative changes which lead to formation of abscesses. 

 Gangrene of these organs is seldom seen. In chronic 

 cases, cystic disease due to accumulation of fluid in the 

 Malpighian corpuscles, with blocking of their tubes and 

 atrophy, are present. Hypertrophy of these corpuscles 

 may often be observed in the undiseased kidney. 



Treatment. — Bleeding is indicated as exerting a seda- 

 tive influence and removing a considerable amount of 

 effete matter from the blood. The bowels and skin should 

 be aroused to activity to relieve the kidneys, Aconite 

 may be required as a febrifuge. Warm water to the 

 loins or the application of a fresh sheep skin to the 

 same part is decidedly beneficial, and warm enemas are 

 useful as fomentations. Digitalis applied as a decoc- 

 tion to the skin is recommended by Williams as a means 

 of exciting the secretion of urine when ursemic intoxica- 

 tion sets in. When pain is excessive, doses of opium 

 must be given. Thoughout the attack cantharides, tur- 

 pentine, and other stimulants which act on the kidneys, 

 must not be applied to the surface. 



Abscess op the Kidney is denoted by passage of a con- 

 siderable amount of pus with the urine. It most often 

 depends on calculus. Little can be done in such cases 

 except to support the strength of the patient. This 

 condition may be secondary, due to emboli or to specific 

 blood diseases. 



Renal Calculus of the ox is not infrequent. Generally 

 there are several of these concretions situated in the 

 calyces of the pelvis. They are irregular in form, are 

 dense and laminated. " And as they increase in size cause 

 absorption of the medullary structure of the kidney, and 

 to a certain extent interfere with the function of the organ. ^' 

 (Morton). They vary considerably in size and in theii'
