Aloes 3 iv. 



Calomel 3 ss. 



Mix with Indian meal and molasses into a ball. 



This dose may be doubled in severe cases, but care must be taken 

 not to continue long enough to salivate. This may be administered once 

 or twice a day. Mustard rubbed occasionally over the region of the 

 liver has often a marked effect in relieving the congestion. The diet 

 should be sparing in quantity, easy of digestion, and somewhat laxative. 



INFLAMMATION OF THE LIVER. 



Synonym. — Hepatitis. 



This is also one of the most rare diseases in the horse, and almost im- 

 possible of diagnosis. 



Etiology. — Similar to those of congestion. It is usually connected 

 with inflammation of some other abdominal organ. 



Ascites, or dropsy of the belly, is said to be a common sequel of the 

 attack. 



ORGANIC DISEASE OF THE LIVER. 



Synonyms.— Cirrhosis; Atrophy; Hypertrophy. 



Definition. — Organic disease of the liver seldom occurs as a primary 

 affection. It is usually a sequel of other diseases, especially of any dis- 

 eases Avhich prevent the free circulation of the blood through it. 



Etiology. — A state of undue accumulation of blood in the capillary 

 vessels is the usual commencement of almost all structural disease. This 

 congestion may arise from any affection which interferes with the passage 

 of the blood into the pulmonary artery, for instance, inflammation of 

 the lungs and pleura, influenza, peritonitis, any violent visceral inflam- 

 mation, valvular disease of the heart, or disease of the pericardium. En- 

 largement of the liver to a great size and softening of its structures often 

 follows low typhoid affections. It is also common in old cart horses. 



On the other hand, atrophy sometimes occurs, and the organ dwindles 

 to half its proper size. 



In some cases, the liver takes on a scirrhous or indurated state, and 

 ceases in a great measure to perform its functions.
