stiffness, cough, labored breathing, intense thirst, constant de- 

 cubitus, and constipation followed by lowering temperature, 

 tarry faeces and icterus. The region of the liver was very 

 sensitive to pressure or percussion. In the other animals the 

 .symptoms appear to be largely over-shadowed by those of the 

 primary di.sease, but the same general indications of jaundice, 

 hepatic tenderness and digestive disorder qre .superadded. 



Treatment when it can be intelligently adopted, con.sists largely 

 in evacuation and antisepsis of the seat of primary infection, and 

 of Xh& prima vice, and in maintaining elimination by the kidneys. 

 In this way, as in congestion and hepatitis, the concentration of 

 the poison is as far as possible counteracted, and an opportunity 

 may .sometimes be furni.shed for the recuperation of the liver 

 cells. As a rule, however, the case is hopeless, and thus pre- 

 ventive measures, by cleanliness, disinfection and antisepsis of 

 the ascertained sources of the infection are indicated. 



PERIHEPATITIS. 



Inflammation of capsule of liver (external and Glisson's). Causes : 

 Traumas, infective diseases, phlebitis of the portal vein, chill, distomatosis. 

 Lesions : Peritonitis and inflammation of the capsule in patches, yellowish 

 gray exudate, fibroid thickening or pus. Adhesions to adjacent objects. 

 Thickening of trabeculse. Symptoms, tardy respiration and circulation, 

 tender hypochondrium, colics, diarrhoea, painful defecation, moan with 

 expiration. Slight cases recover. Sequelae: compression of portal vein or 

 bile duct, gastric catarrh, piles, etc. Treatment : Salines, alkaline diuretics, 

 mineral tonics, bitters. 



This is inflammation of the external cap.sule of the liver and 

 Glisson's capsule. It may arise from direct mechanical injury, 

 or by extension of inflammation from adjacent structures, such 

 as the peritoneum. It may also complicate contagious pneumonia 

 in the horse, tuberculosis in the ox, pneumoenteritis in pigs, and 

 also phlebitis of the vena portse (Cadeac, Morot). It may follow 

 a chill, or distomatosis. 



Lesions. The.se are essentially peritonitis circumscribed by the 

 liver, and extending to the proper capsule, and its vaginal invest-
