THOROUGH-PIN". 203 



pletely covering the swelling, but not surrounding the leg. 

 The blister should be applied every third or fourth day, but 

 not putting on new ones while the other runs, until three or 

 four blisters have been put on. But the most permanent cure 

 is firing. The horse should be cast ; then several strokes ^vith 

 the firing-iron should be made over the swollen part, nearly up 

 and down the limb, about half an inch apart; other strokes 

 with the iron are to be made, running slantingly across the 

 first, marking the surface over and around the swelling in dia- 

 monds. The burning should not go through the skin, but nearly 

 so. After five or six days, a blister should be drawn over the 

 part fired. By this treatment the skin is contracted, and a 

 constant pressure is kept up on the parts that were swollen. 

 Never blister twice, without greasing and washing with warm 

 water and soap, then drying before blistering. 



THOROUGH-PIN. 



An enlargement, of a soft, puffy character, appearing in the 

 space between the hamstring and the lower end of the thigh- 

 bone, above the hough. 



It is an enlargement of one of those little sacks placed in 

 the neighborhood of joints and ligaments, called hirsm mncosce, 

 and which are particularly described in the article on "Wind- 

 galls." Indeed, thorough-pin is identically of the same char- 

 acter as wind-galls. The enlargement may appear only in 

 one of the spaces in front of the hamstring; but it generally 

 appears at both sides — hence the name thorough-pin. The en- 

 largement may be small or of considerable size, somewhat 

 injuring the appearance of the hough; but it is only an eye- 

 sore, seldom producing. lameness, and is not regarded as an un- 

 soundness, though it is an evidence of the horse having passed 

 through some rough usage. From the above description it 

 will readily be recognized or known, and its causes sufficiently 

 understood.
