100 DISEASES OF HORSES AND CATTLE. 



pulse becomes weak, and the breathing short and 

 quick, and the legs and ears are cold; and in cattle 

 the membrane of the nose is dry and cold, there is 

 general stiffness, and in the horse swellings appear 

 on the legs and under the belly. In cattle gener- 

 ally under the belly and in the dewlap. The horse 

 generally stands through the disease, but cattle 

 will lie down on their right side. The animal 

 moans and grinds its teeth, and looks around every

 takes place in the cavity you can, on applying the 

 ear to the left side, hear a splash at each beat of 

 the heart. After death I have found a large quan- 

 tity of liquid around the heart, and in some cases 

 a regular covering of cheesy pus between the heart 

 and the sack. In several cases of cows, which have 

 died from this disease, I have found a piece of darn- 

 ing needle, which had made its way from the stom- 

 ach to the heart, setting up inflammation, causing 

 death. It is strange how many cases of this kind 

 are reported to have taken place in cows. 



Endocarditis. — Inflammation of the inner lining 

 of the heart, and is usually complicated with rheu- 

 matic disease. This is a very dangerous disease, 

 and if it does not kill in the acute stage it is very 

 likely to leave thickening of the valves of the heart, 

 which will interfere with the passage of the blood 

 through the heart, preventing the animal from 

 doing fast or heavy work. 



Symptoms: There is a very decided interference 

 with the action of the heart; the beat is very irreg- 

 ular and violent in its action, compared with the
