In tlio eases j)rodiieed by low temperatures and deep snoAvthe coronary 

 l)and is the j>art most often affected. 



In many instances there is no destruction of the skin, but simply a 

 temporary suspension of the horn-producing function of the coronary 

 band. The fore feet are more often affected than the hind ones, and 

 for some reason the heels and quarters are less often involved than 

 the front part of the foot. The coronarj^ band becomes hot, swollen 

 and painful, and after two or three days' time the horn separates from 

 the band and slight suppuration follows. For a few days the animal 

 is lame, but as the suppuration disappears the lameness subsides; 

 new horn, often of an inferior quality, is produced by the coronary 

 band, and in time the cleft is grown off and complete recover^'' is 

 effected. The frog is occasionally frost bitten and may slough off, 

 exposing the soft tissues beneath and causing severe lameness for a 

 time. 



Treatment. — Simple frost bites are best treated by cold fomentations 

 followed by applications of a 5 per cent solution of carbolized oil. 

 When i)ortions of the skin are destroyed their early sejDaration should 

 be hastened by warm fomentations and x)onltices. Ulcers are to be 

 treated by the apx)lication of stimulating dressings such as carbolized 

 oil, a 1 per cent, solution of nitrate of silver or of chloride of zinc, with 

 pads of oakum and flannel bandages. In many of these cases recovery 

 is exceedingly slow. The new tissue hy which the destroyed skin is 

 rei:»laced always shrinks in healing, and as a consequence unsightlj^ 

 scars are unavoidable. Where the coronary band is involved it is 

 generally advisable to blister the coronet over tlie seat of injury as soon 

 as the suppuration ceases, for the purpose of stimulating the growth 

 of nevr horn. Where a crevasse is formed between the old and new 

 horn, no serious trouble is likely to be met with until the cleft is 

 nearly grown out, when the soft tissues may be exposed by a break- 

 ing off of the partly detached horn. 



But even where this accident happens final recovery is secured by 

 poulticing the foot until a sufficient growth of horn protects the part 

 from injur}'. 



(^UITTOR. 



Quittor is a term applied to various affections of the foot wherein 

 the tissues which are involved undergo a j)rocess of degeneration that 

 results in the formation of a slough, followed by the elimination 

 of the diseased structures by means of a more or less extensive 

 suppuration. 



For convenience of consideration quittors may be divided into four 

 classes, as suggested by Girard: (1) Cutaneous quittor, which is 

 known also as simple quittor, skin quittor, and carbuncle of the coro- 

 net; (2) tendinous quittor; (;3) subhorny quittor; and (4) cartilagi- 

 nous (piittor.
