QUITTOR. 329 



below the abscess ; thin down the sole even to the quick, 

 and allow the pus to escape ; use a probe, and ascertain, if 

 possible, what structures are diseased. In cases where the 

 pus has forced its way out at the coronet, the shoe may be 

 removed and the sole cut down, when in many cases it will 

 be found that the pus has burrowed right through until 

 checked by the horny sole — in such a case a dependent 

 opening should also be made. It is often found necessary 

 to cut down the wall below the seat of the injury. In 

 some cases the sinus may be pared out, a proceeding that 

 will cause considerable ha?morrhage, or it may be neces- 

 sary to strip off a portion of the wall. Any of these 

 operations may causi; considerable irritation, which may 

 be allayed by fomentations and poultices. Hydrarg. per- 

 chlor. in solution may be used to inject the sinus, or 

 grs. ii. — iii. may be wrapped up in tissue paper, made into 

 the form of a cone, and pushed down into the sinus ; in two 

 or three days a slough separates and comes away. If the 

 wound now looks red and healthy, treat with mild astrin- 

 gent and anodyne lotions ; if it still looks pale and un- 

 healthy, repeat the operation until the wound takes on a 

 healthy appearance. This is known as ' coring out.' If the 

 lateral cartilages are affected, it constitutes a more serious 

 case, and the foot will probably become deformed, and 

 remain so. As a rule quittor can be guarded against, but 

 occasionally a caulk will degenerate into a quittor in spite 

 of all the treatment that can be brought to bear. Some- 

 times it may be necessary to cast the animal before a proper 

 examination of the parts can be made. After the discharge 

 ceases and the wound heals, there may be some slight 

 tenderness of the parts remaining, in which case a vesicant 

 will be of use. If the lateral cartilages are diseased pretty 

 extensively, it may be necessary to remove them. Quittor 

 is an unsoundness in all its stages.
