tant bloodvessels, and in most cases ceases of its own accord. 

 In the event of any of the more important bloodvessels 

 being divided, the haemorrhage may be checked in the usual 

 way. In some cases it may be necessary to remove the 

 exudate b}^ means of a knife. After laying the parts open 

 it should be treated as an ordinary wound. Treatment is 

 usually successful, except when the bones are affected. 



Halter Cast. — Horses frequently become halter cast, and 

 as a rule more or less injury results. The animal usually 

 struggles violently in his endeavours to free himself. If 

 the animal has been cast for any considerable length of 

 time the muscles may lose their power of contracting, and 

 on this account the animal on rising may not be able to 

 elevate his head to its proper position. The head hangs 

 down until the nose nearly, or in some cases quite, reaches 

 to, and rests upon the ground, and mechanical congestion 

 of the head takes place, the lips frequently becoming swollen 

 to an enormous degree, and respiration interfered with to a 

 considerable extent. 



Treatment. — If the animal is unable to raise his head, it 

 should be elevated and supported in its proper place by 

 means of a broad bandage, an ordinary sack answering the 

 purpose very well. The swelling of the lips and other parts 

 is to be relieved by scarifying freely, and applying cold 

 water, etc. The neck should be bathed and well dried 

 afterward, and in cold weather a stimulating liniment 

 should be applied to prevent reaction. Pus sometimes 

 forms, and should be allowed to escape ; give laxatives, 

 diuretics, etc.
