INFLAMMATION OF THE JUGULAR VEIN. 



In the horse the jugulars are single on both sides 

 of the neck, while in horned cattle they are double. 

 Inflammation is sometimes induced in them after the 

 operation of bleeding, directions for which we shall 

 give hereafter. 



After bleeding has been performed, the practice is 

 to bring the cut edges of the vein together, and to 

 keep them in contact by inserting a pin through the 

 skin above it, and twisting tow pretty tightly round it, 

 so as to keep it from being removed. In three or four 

 days the wound will have completely healed in most 

 cases. 



Causes. — A variety of causes may, however, 

 operate to induce inflammation of the vein. Among 

 these may be enumerated, striking too hard on the 

 lancet with the fleam (an instrument used in bleeding), 

 or using a blunt or rusty lancet. In other cases, by 

 pulling the skin too far from the neck while drawing 

 the wound together, and thus allowing space for the 

 blood to insinuate itself into the cellular tissue ; or 

 working the horse immediately after the operation ; 

 or neglecting to tie up his head for a short while after 

 bleeding, to prevent his removing the pressure of the 

 pin from the wound by rubbing his head against the 

 manger ; and other causes. 



Symptoms. — Swelling and separation of the cut 

 edofes of the wound ; coag-ulation of blood within the 

 channel of the vein ; inflammation and thickening of 

 the wall of the vessel, so that it feels like a cord under 

 the finger. The obliteration of the jugular may ex- 

 tend from the point of operation to the base of the 

 brain. This is generally followed by a series of small
