character of the tumor, and the little or no inconvenience oc- 

 casioned by them. 



Treatment. — Constant and firm pressure will remove wind- 

 galls for a short time, but they will return. The daily appli- 

 cation of tincture of iodine will sometimes remove them, but a 

 certain cure is to puncture the wind-gall with a sharp knife, 

 and with a glass syringe inject into it a tea-spoonful of tincture 

 of iodine. 



BOa AND BLOOD-SPAVIN. 



As was observed when describing wind-galls, where the ten- 

 dons pass over the bones, little membranous sacks or bags are 

 interposed to prevent friction. A similar arangement of little 

 sacks protects the tendons about the hough. From violent ex- 

 ertion, inflammation is excited in these little sacks; their natural 

 secretion is changed in character and increased in quantity, and 

 a tumor or lump is formed. A vein of considerable size, called 

 the subcutaneous vein, passes up the leg a little in front of the 

 inside of the hough. Now, when the little sacks situated be- 

 neath this vein inflame and enlarge, they press on the vein, 

 preventing the blood from returning freely along it, and a por- 

 tion of the vein, below the enlarged sack, swells, forming a 

 tumor of a soft and yielding character, seldom larger than half 

 of a hen's egg. 



Symptoms. — The symptoms by which blood-spavin can be 

 distinguished are, the commencement of the vein to enlarge 

 below the swelled or enlarged sack, and its gradual progress of 

 development; also, the slight lameness accompanying, which is 

 most manifest when the animal first starts, after rest. This 

 lameness is often permanent. Blood-spavin should always be 

 regarded as permanent unsoundness, for, though it may be 

 cured, it is almost certain to return again. 



The causes of this difficulty have been sufficiently referred 

 to above. 



Treatment. — I should lose no time in applying a blister, com-
