54 MANUAL OF MODERN FARRIERY 



Space for tlie blood to insinuate itself into the cellular 

 tissue ; or working tlie horse immediately after the opera- 

 tion ; 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. — The edges of the wound having separated, 

 or being ragged, from the clumsiness of the operator in not 

 penetrating the vein at the first blow, become swelled -and 

 inflamed, and discharge a thin fluid of a bloody appearance. 

 In a day or two this will put on the form of matter. In- 

 flammation to a considerable extent may ensue, with 

 swelling of the muscle, and the vein will become hard, and 

 feel like a cord, and increasing upwards, the contiguous parts 

 will feel very hot. This is gc^nerally followed by a series ol 

 small abscesses over the seat of the wound. The cordines5 

 of the wound gradually increases still further upwards ; and 

 from the inflammation also following that direction, it fre- 

 quently proves fatal to the horse. 



Remedies. — Some veterinary surgeons, to stimulate the 

 part, apply a hot iron to the margin of the orifice, which 

 induces a union of its edges. Should this not prove 

 efiectual, and if the swelling is great and the abscesses have 

 made their appearance, the next remedies are to inject a 

 weak solution of nitrate of silver or other caustic liquid 

 into the abscesses, or to introduce setons into them ; and 

 should this fail, he should cut out the diseased portion of 

 the vein. 



This operation will not be attended with any bad conse- 

 quences ; for all the blood-vessels, whether veins or arteries, 

 communicate with each other either directly or indirectly, 

 in so many different ways, that an injury sustained by a 

 portion of them is compensated for by the current of the blood
