Diseases of the Sean. 207 



Treatment is in the main the same as for pericarditis, 

 rest, laxatives, sedatives and blisters being mainly relied 

 upon. As there is less danger from effusion diuretics need 

 not be pushed to the same extent. In rheumatic eases, 

 adopt antirheumatic treatment, and ia case of clots on 

 the valves use iodide of potassium and alkalies. 



CAEDITIS. 



Inflammation of the muscular substance of the heart 

 can only take place to a limited extent in connection 

 with endocarditis and pericarditis, or with punctures from 

 sharp bodies and the like. Were the entire organ involved 

 death would be prompt. The symptoms are those of acute 

 heart-disease generally, modified by the exact seat of the 

 injury, and treatment need not differ materially from that 

 adapted to the two diseases just described. 



CHEONIO TAlVnLAB DISEASE. 



With the general symptoms of chronic heart-disease, 

 there are blowing murmurs as described in the table under 

 auscultation of the heart. This is a very common result of 

 endocarditis and is irremediable. Yet affected cattle, 

 sheep and pigs may often be prepared for the butcher by 

 liberal feeding and perfect quiet. 



FATTY DEGENEBATION OF THE HEAET. 



This is most frequent in high-bred stock (Shorthorns, 

 Berkshire and Essex pigs, Leicester and Southdown 

 sheep,) but may exist in any pampered animal. Some- 

 times it is compKcated by degeneration of the entire 

 muscular system, especially in pigs. There are the gen- 

 eral phenomena of chronic heart-disease and dilatation, and 

 the condition is irremediable, though it rarely kills animals 

 kept in perfect quiet. 



BUPTUEE OF THE HEART. 



If from severe exertion this usually takes place througl,
