DISORDERS OF THE HEART. 257 



Inflammation of the Heart (carditis) may be an ac- 

 companiment of either pericarditis or endocarditis. The 

 muscular substance of the heart is sometimes inflamed 

 near a deposit or seat of injury. Usually fatal. 



Foreign Bodies in the Heart, such as pins, nails, 

 &c, is not uncommon. An animal may live some time 

 with a needle in its heart. If practicable, fatten and 

 slaughter. 



Enlargement of the Heart (hypertrophy) is not un- 

 common. 



Embolism is plugging a vessel, such as the iliac ar- 

 teries, the most usual seat of the disorder, with clots of 

 fibrin (a constituent part of the blood), lymph, &c.
