Treatment. — The treatment for thoroiigli-pin is the same as 

 recommended for wind-galls. 



CURB. 



An inflammation and swelling, terminating in a callous 

 tmiior or swelling, about three or four inches below the hough. 



It should be borne in mind that many tendons are held in 

 place by broad, ring-like ligaments, through which the tendons 

 pass, these ring-like ligaments being firmly attached to the 

 bone. These loops, or rings, are lined with a smooth mem- 

 brane, which secretes a fluid to keep it as if oiled, to avoid fric- 

 tion. The tendon is also covered with a smooth, delicate mem- 

 brane, called its sheath, to further aid in preventing friction, 

 by the motion of the tendon. But by violence to the part 

 above described, either to the sheath of the tendon or the ring- 

 like ligament, inflammation is excited, giving rise to the fol- 

 lowing 



Sfpnjytoms. — Heat, tenderness, and swelling in the part affected, 

 wdth considerable lameness from the first, are the usual symp- 

 toms of the earlier stage of this malady. The heat and ten- 

 derness will only be observed in the first or inflammatory stage. 

 After this, the presence of the callous tumor, or swelling, will 

 be the only local symptom of curb ; and this may present 

 such a uniform elevation as to be overlooked, even by an expe- 

 rienced eye. Its size varies considerably, sometimes being so 

 small as to be but barely perceptible ; in other cases, so largo 

 as to present the appearance of deformity. 



In examining curb, the hand should always be used, as it is 

 important to ascertain not only the existence of the tumor, but 

 its size and the stage of its progress, by which a better idea 

 can be given of the prospects of treatment. 



After the inflammation subsides, the lameness does not en- 

 tirely disappear, but is not so great as at first, and is of some- 

 what different character; and, indeed, might be called a stiff-
