sloughs out. 3d. The sub-liorny quittor , the furuncle of the cuti- 
dura of the coronary band itself, the slough involving the superior 
portion of the laminated tissue. 4th. The cartilaginous guittor , 
or the limited caries of the lateral fibro-cartilage of the os pedis, 
and which old writers compounded with the horny quittor. We 
might join to those the furuncle of the frog, (see vol. 6, page 204). 
We believe it useless at present to enter upon a general consider¬ 
ation upon quittor, and will proceed to examine the pathological 
phenomena presented by each variety. 
A. —Cutaneous Quittor. —This is a simple furuncle of the 
coronary region of the foot, in that part of the dermis nearest to 
the coronary band, having, however, a special character on account 
of the extraordinary thickness and inelasticity of the dermis of 
the region it occupies, the result being a kind of strangulation of 
the inflamed tissue beneath, and a very painful compression. It 
is through error that some authors have designated by the same 
name, the furuncle of the canon, of the fetlock, and of the coro¬ 
net. 
The hind feet are more subject to it than the fore, and it is 
more frequent at the heels, at the flexure of the fetlock, though 
it is also observed on the sides and front of the coronet, in which 
case it is much more painful. Cutaneous quittor has also been 
observed in bovines, where, however, as we shall see as we pro¬ 
ceed, it is generally complicated with the tendinous variety, and 
becomes a true felon. 
I.— Symqrtoms .—Cutaneous quittor is characterized by an in¬ 
flammatory tumor or swelling, warm, painful, and tense, of the 
coronary region of the foot, the color of the skin being but little 
changed', if it is dark, but if the skin is light then the red¬ 
ness is well marked. This swelling is accompanied with a diffused 
sedema, extending to the fetlock, or even to the hock. We often 
find angeioleucites, or rather what we call leucophlegmasise. The 
lameness is generally extreme, and the animal frequently can 
scarcely rest on the diseased leg. The pain is sometimes so great 
as to induce general fever and loss of appetite, and the animal 
becomes dull and depressed. After acquiring certain dimensions 
the tumor shows a tendency to soften at its summit, its base, how-
