If matter forms at another spot and points, it should merely be 

 opened with a lancet ; but the knife should be used spavinglj^, 

 and setons should be avoided, as well as the plan of dissecting 

 out the diseased vein or Its contents. In some instances, there 

 is considerable hgemorrhage; when this is the case, a little caustic 

 powder, such as the sulphate of copper, should be applied to the 

 lips of the wound; and the horse's head being tied up, he should 

 be kept from feeding for twelve hours. This plan will generally 

 succeed in stopping the bleeding ; but if it fail, the orifice must 

 be pinned up, or, if necessary, two small pins may be inserted, 

 and tow wound round each. 



If the parotid gland continues enlarged, a little iodine oint- 

 ment may be rubbed in daily several times. I have not found 

 any inconvenience from turning horses to grass subsequent to 

 the loss of a vein ; the principal evil is the circumstance that we 

 cannot bleed on the side the vein is lost. 



The proximate causes of inflamed vein are very obscure. 

 Bleeding with a rusty instrument, striking too hard, cutting 

 througi^or across the vein, badly pinning up, neglecting to tie up 

 the head, rubbing the neck afterwards, have all been considered 

 as causes: but it has been found that, when these supposed 

 agents have been purposely tried, they have failed in producing 

 an inflamed vein; whilst it has occurred when the operation 

 has been properly performed, and every precaution exercised. 

 It must, however, be confessed that it occurs much more fre- 

 quently when the operation is performed in a bungling manner, 

 and proper means neglected afterwards. It may, however,' 

 depend, in some measure, on the state of the atmosphere ; for, 

 at some periods, the disease is much more frequent than at 

 others ; and it may also be influenced by the constitution of the 

 animal. It has been a matter of surprise that the swelling 

 should almost invariably extend towards the head in inflamed 

 jugular vein; but this is produced by the blood being rendered 

 stagnant at this part, and not below; the inflammation probably 

 does not extend more in one direction than the other; but as 

 soon as it is sufhcient to produce a stoppage In the vein, it of 

 course occasions it to swell above. — Ed.J

 after they arc taken up from grass, or the straw yard, and when 

 they are getting into condition by suitable feeding and exercise:
