Sjmaptoms. The heart beats may be violent enough to jar the whole 

 body, and often it may be heard quite a distance from the animal. The 

 jar will correspond to the beating of the heart. This disease can usually 

 be traced to the cause, which may be avoided or overcome in the future. 

 Rest, a mild stimulant, or a dose or two of tincture of opium or tincture 

 of digitalis will generally give relief. It must be regarded as a symp- 

 tom when organic. 



iEnlargemeiit of the Heart. Hypertrophy of the heart, or car- 

 diac enlargement frequently follows an increased demand for propelling 

 power. 



Symptoms. In addition to the usual symptoms manifested in or- 

 ganic diseases of the heart, there is a painful and heavy pulsation at each 

 heartbeat. These pulsations are regular. When full and strong at the 

 jaw, there is a tendency to congestion of the capillary vessels, but if 

 small and feeble an obstacle to the escape of blood may be suspected. 



Treatm.etit. If the cause can be discovered and removed it should 

 be done. Hydrocyanic acid in thirty drop doses twice a day, may re- 

 lieve muscular irritabilitJ^ Give general tonic, avoid overwork or ex- 

 citement as well as bulky food. 



DISEASES OF THE ARTERIES. 



Inflammation of the Artery. This disease is rarely observed in 

 the horse as a primary disease. It may extend only to the inner coat 

 or it may involve all of the layers of which there are three. 



Symptoms. There will be a painful swelling along the inflamed 

 vessels, throbbing pulse, coldness of the parts fed by the inflamed 

 artery. 



Treatment. Give one-dram doses of the carbonate of potassium 

 mixed with four ounces of liquor acetate of ammonia, every six hours. 

 Feed scalded bran enough to produce loosening of the bowels. Put on 

 applications of hot water or hot hop infusions. 



DISEASES OF THE VEINS. 



Phlebitis. Inflammation of veins may be confined to a limited por- 

 tion of a vein or it may attack the vein for a long distance, occasionally 

 extending from a limb or foot to the heart.
