230 INJURIES. 



tured ; the cartilaginous substance underneath this is broken 

 down. No wonder if a wound on so complicated a structure 

 should require care to promote its healing. It has to cast 

 off a slough; the chasm thereby exposed has to granulate, and 

 the sore has to cicatrize. 



The Treatment consists in promoting these processes. 

 With a pair of sharp scissors, we cut off the surrounding 

 hair. Horn once separated from the living parts underneath, 

 can never again become united to them ; consequently, its 

 presence can only serve to irritate, and harbour dirt, as the 

 surrounding hair has a tendency to doj therefore, both 

 ought to be removed — cut closely off. Then we immerse 

 the foot in a tub of warm water. Lastly, we dress it with 

 nitric acid lotion, and envelop it in a hot poultice. As soon 

 as the slough has come away, and the surface looks clean, 

 apply turpentine dressings. When the heat of the inflam- 

 mation has passed, and the parts have commenced healing, 

 leave off the poultices, and openly expose the wound : be 

 sure, however, to keep it clean and free from any hair that 

 may annoy it. 



QUITTOR. 



A quitter is a sore on the coronet connected with a sinus 

 in the foot. The usual seat of the disease is the inner side 

 of the coronet of the hind foot. It appears as a conical 

 tumour, sometimes so painful as to occasion considerable 

 lameness. Its maturation is commonly tardy ; and, after 

 all, imperfect. At first the tumour is so enveloped in lon^ 

 hair as to be with difficulty discoverable : but as soon as it 

 begins to point, the hair falls off, leaving the place nearly 

 bare. 



Cause. — The suggestions associated with the seat of quit- 

 tor, together with the fact of cart-horses being the common 

 subjects of it, tend to elucidate the ordinary way of its pro- 

 duction. Every body knows what awkward contrivances the 

 calkins of cart-horses' hind shoes are, and it need excite no 

 surprise if they often injure their wearers. The projections
