DISiSASES OF THB CIRCULATORY ORGANS. 99 



Symptoms vary according to the extent and the severity of the in- 

 flammation. The vein is usually swiollen and thickened so as to resem- 

 ble an artery. 



What to Do. Apply a smart blister over the affected part; open 

 any abscess that may be formed; give animal complete rest; and keep 

 bowels loose with bran mashes. When fever runs high give half-ounce 

 doses of nitrate of potassium, in the drinking water, which may be 

 changed in two or three days for dram doses of the iodide of potassium. 

 Give animal carbonate of ammonia, one dram, and powdered gentian 

 three drams every six hours should the animal show great weakness. 



Varicose Veins. Otherwise named varix, and dilatation of veins. 

 This disease is the result of weakening of the coats of the veins from in- 

 flammatory diseases. The vein which lies near the surface on the inside 

 of the hock- joint is sometimes affected. This is sometimes due to the 

 pressure of a spavin. It is occasionally seen in stallions as dilatation of 

 the cord of the testicles. Piles or hemorrhoidal veins are occasionally 

 met with, principally in horses which run at pasture. 



Treatment. Piles may often be reduced by astringent washes — tea 

 made from white oak bark or a saturated solution of alum. Stallions 

 having enlarged testicular chord should wear suspensory bags, when ex- 

 ercised. 



DISEASES OF THE LYMPHATIC SYSTEM. 



Inflammation of the I/ymphatic Structures. This inflamma- 

 tion usually effects a hind-leg, very seldom a fore-leg. This application 

 is sudden in its attack, exceedingly painful, accompanied by a high tem- 

 perature, and great general disturbance. 



Syniptoms. Usually commences with a chill, rise in temperature, 

 and some uneasiness; in a short time it is followed by lameness in one 

 leg and swelling on the inside of the thigh. The limb is very tender to 

 the touch; the animal perspires; the breathing is accelerated; pulse hard 

 and quick; and the temperature may reach 106° F. The bowels become 

 constipated; urine becomes scanty; symptoms on the increase for about 

 two days, then stationary for same time; the fever then lowers; swelling 

 goes down and becomes less painful. The swelling seldom all leaves the 

 leg; there is left behind a permanent enlargement, and attacks return 

 occasionally.
