POLL-EVIL IN ITS SECOND STAGE. 



In the course of a week or so, pipes form, and their walls get thicker 

 and thicker as they are allowed to run. 



What to do. — As in the treatment of all fistulous sores, the sinuses 

 must be opened up and a free dependent opening made for the pus. It is 

 more ditiScult to do this in poll-evil than in almost any other case ; but 



the sinuses usually run down into the 

 muscle of the neck more or less. 

 Follow them and open them up 

 freely ; then, there being a free con- 

 nection between the top of the sore 

 and the bottom of the sinuses, wash 

 it out thoroughly and inject lotion 

 No. 5, twice a day. If it is noticed 

 in its incipient stage, apply a linseed 

 poultice, hot and soft, till it is ready 

 to open ; then open it and inject 

 lotion No. 5, twice a day; continue the poultice till the holes all fill up 

 with fine, solid, healthy, granulations ; then apply lotion No. 7, three 

 times a day. If the bones are affected so as to expose a caried surface, 

 wash them off with warm water and scrape the rough surface to expose 

 the healthy bone; then dress it by applying lotion No. 28, twice a day 

 v/ith a swab till the exposed surface of the bone granulates so as to feel 

 like velvet when touched with the finger; then change to lotion No. 29. 

 Alternate lotions No. 29 and No. 5, one Aveek on and one week off. If 

 proud flesh springs up, keep it down with powdered bluestone. 

 XVn. Inflamed Jugular Vein. 

 Causes. — This disease is not so common as it used to be in the days of 

 bleeding. Bleeding is rarely resorted to now-a-days ; hence the infre- 

 quency of this trouble, for it is always the possible sequence of bleeding. 

 As the effect of this inflammation, the vein is liable to become obliterated, 

 filled up and caloused so as to remain so, the work of returning the blood 

 to the heart being done by the vein on the other side of the neck. 



A horse with a jugular vein obliterated, cannot graze on account of the 



rush of blood to the head, owing 

 to the lessened capacity to return 

 the blood from the head freely. 



How to know it. — In the active 

 stage of inflammation the vein and 

 contiguous parts will be swollen, 

 sore and hot. In the later, chronic
