I.— Symptoms .—The first symptom is an excessive lameness, 
manifesting itself even where no visible change exists in the 
affected leg. The animal evidently suffers great pain, while his 
actions do not aid us in localizing it accurately, though the foot 
is always examined as being the probable seat of it, the animal 
raising it more rapidly than the other from the ground, and rest 
ing on it with much caution and hesitation. After from two to 
five days a phlegmonous tumor appears at the coronet, above the 
heel. It is extremely warm, and much more painful than that 
in cutaneous quittor, the hoof and the skin preventing the free 
development of the inflammation by strangulating it. The foot 
almost ceases to rest on the ground, but is flexed and raised from 
it, feeling in the parts being very painful. The swelling of the 
leg extends to the fetlock, or to the cannons, and even to the 
knee. The animal has more or less fever, and when there is a 
deep quittor he loses all his appetite, and ordinarily lies down 
and continues in the recumbent posture. 
Generally, much time is required for the phlegmon to assume 
the character of an abscess, as the slough, being in this case no 
longer formed by the cellular tissue, is slower to define itself. 
The process of suppuration is not so well localized ; there is, 
on the contrary, a kind of deep abscess, which probably becomes 
complicated by the resistance opposed to the ulcerative inflamma¬ 
tion by the aponeurosis of the sheath and the thickness of the 
skin. However this may be, it is always very difficult to recog¬ 
nize the presence of one or several of these abscesses, even when 
they form in the subcutaneous cellular tissue, and so much the 
more if the purulent gathering is deeply seated. 
After the opening of the abscess and exfoliation of the slough, 
either with or without the dropping of a portion of the skin, there 
does not remain the simple wound of the cutaneous quittor, but 
on the contrary, a persistent fistula, running down a necrosed 
point of the tendons or of the fibrous sheathes. At times, 
almost from the outset, we may observe in the fold of the coronet 
numerous little pimples, which terminate in as many deep fistulse, 
from which ooze a more or less thick humor, foetid, puriform and 
bloody. In infrequent cases, the disease is unaccompanied with
