 and take the place of the lost jugular. He is not suited to be turned 

 to pasture* as the head is apt to swell. He can never after be passed 

 as a sound horse. 



Thrombus. 



Thrombus is the name given to a round tumor which sometimes 

 occurs around the puncture made in bleeding. 



Causes. — It is usually the result of pinning up the wound by 

 drawing the skin out, allowing the blood to be extravasated into 

 the cellular tissues; also from the opening in the skin not being 

 opposite the opening in the vein, or too small to allow the blood to 

 escape freely ; often from the tissues being irritated by repeated 



striking of the fleam, or " perhaps from 

 spontaneous inflammation and serous 

 effusion in the divided integuments 

 and membranes themselves." 



Symptoms. .— r-It is easily recognized 

 by the appearance of a round, full 

 swelling surrounding the opening a

the edges of the wound again brought together, and a pad or 

 sponge saturated with a strong solution of Goulard's lotion, or cold 

 water constantly applied for an hour at a time, the pad being sup- 

 ported by a broad bandage round the neck. The head must be tied 

 up for at least twenty-fqur hours. It usually subsides in a day or 

 two. Should swelling remain, it should be blistered and treated as 

 in phlebitis. 



' Lampas. 



Lampas is the name given to a slight enlargement of the bars 

 or ridges on the palate behind the incisor teeth. It is mostly con- 

 fined to young horses, and is a natural conjestion of these parts, 

 consequent on the shedding of the teeth. It is not so much a 

 disease as a natural and salutary process, which in general is best 

 let alone, and in which cruel remedies, such as firing, should never 

 for a moment be thought of. If much inflamed, a slight scarifica- 

 tion, with sloppy feed for a few weeks, will suffice to remove it. 

 In older animals, similar swellings are sometimes seen arising from 

 indigestion ; a slight physicking wilj generally remove them, with- 

 out resorting to such outri practices as " cutting out the lampas."
