190 PPvACTICE OF EQUINE MEDICINE. 



The fatty liver is uniformly increased in size, is smooth, blood- 

 less, and looks pale or yellowish; on section, it is dry and the surface 

 of the knife is greasy. The organ may weigh more, but its specific 

 gravity is less, and it may float in water. 



Give the symptoms. 



These are not definite. Jaundice may be present in some 

 cases. The stools may be light colored. Horses subject to colic 

 or those that show colicky pains at varying intervals often have 

 fatty livers. 



Outline the treatment. 



Moderate exercise, limited diet, with occasional saline pur- 

 gatives, diuretics, or diaphoretics. 



7. DISEASES OF THE SPLEEN. 



It is rare to find diseases of this organ in our animals. Its 

 functions are somewhat obscure, and it being situated out of our 

 reach we are unable to tell its condition. Most all of its affec- 

 tions are, however, usually secondary. 



The organ may, however, become congested, inflamed; it may 

 contain new growths, or, again, it may rupture. 



Emboli are here found. 



SPLENITIS. 



Define splenitis. 



This is an inflammation of the spleen, and is rare in the horse, 

 being more frequent in the bovine race. 



The spleen may become enlarged, which is often interesting 

 on post mortem; as in glanders, leucocythaemia, tuberculosis. 



It may become enlarged during certain fevers, also in con- 

 junction with certain diseases of the liver; in the human subject, 

 in malarial fever. 



Amyloid degeneration may take place. 



What is the treatment? 



Ascertain the cause and treatment of affection with which it 

 is associated.
