often found right under the coat of the vessel where it sets up 

 an inflammation. Other worms may cause this condition. The 

 ihac artery in females is sometimes injured in parturition, set- 

 ting up ill results. 



The most common result is the formation of a thrombus at 

 the point of inflammation. It may grow so as to obstruct the ves- 

 sel and it is then spoken of as thrombosis of the artery. The par- 

 tially organized lymph may become detached and float off to some 

 other part, as an embolus. When an embolus reaches a vessel 

 too small for it to pass, it becomes lodged and plugs the vessel, 

 producing cmholism. 



Treatment. — Embolism is incurable and thrombosis may pro- 

 duce serious results. Thrombosis must be treated with hot or 

 cold applications externally and internally — acetanilid, quinine 

 and belladonna. In case of arteritis of the iliacs give a laxative 

 and cold rectal injections (60 degrees F.) with a little belladonna 

 in it. Keep the animal warm in cold weather. 



ANEURISM. 



Aneurism is a dilatation of an artery and it is sometimes 

 called a pulsating tumor. This may be the result of one or two 

 causes. First may be mentioned weakness of the arterial walls, 

 which the pressure dilates. The walls may get very thin and 

 sometimes rupture and the animal bleeds to death. This condi- 

 tion usually occurs in the posterior aorta. Worms may cause 

 aneurism, especially in the colic artery. 



If the aneurism is external, apply pressure in the form of a 

 truss. If it is in a vessel that can be dispensed with, ligate it. 

 It may occur from stricture caused by arteritis, the dilatation be- 

 ing anterior to it. 



PHLEBITIS. 



Inflammation of the veins, is called phlebitis and it is either 

 traumatic or idiopathic — idiopathic as regards its origin. In the 

 horse it is usually traumatic. As the result of the inflammation 

 there is extensive exudation into the vein, which finally becomes
