ever, remaining hard for a considerable time. .Rising more and 
more, it soon ulcerates at a point from which flows a small quan¬ 
tity of bloody pus, followed by the appearance of the slough, 
( bourbillon ). An abscess is now formed in the tumor,which, as it 
opens, carries with it a portion of the skin, sometimes limited, 
at others measuring from four to ten centimeters, and there is a 
slough formed of the subcutaneous cellular tissue which separates 
by the suppuration with the portion of dead skin. This comes 
out by degrees. is still adherent by its base and cannot be 
pulled out with the forceps unless by tearing and with acute pain, 
and this is often followed by slight hemorrhage. A few days 
later it will, however, become entirely loose, and in its place there 
will remain a cylindroid open cavity extending through the tumor, 
from its summit to its bottom, and from this a deep wound results, 
followed by a sero-bloody secretion, mingled with pus. As soon as 
the slough has taken place, or when it begins, the lameness sub¬ 
sides, as well as all the other phenomena of the pain. The wound 
heals up rapidly if there is no complication. 
Cutaneous may easily be complicated with tendinous quittor if 
the disease or process of sloughing of the mortified tissues extends 
to the tendons or ligaments of the region involved. This com¬ 
plication is specially common in bovines, where cutaneous quittor 
generally gives rise to more swelling and greater suffering than 
the horse. 
This quittor has quite a rapid progress, and may last from eight 
to fifteen days ; very seldom longer. At times it seems to be a 
single furuncle; at other times there are several existing 
together. Often again, they come in succession, the first one 
treated being soon followed by others. This is said to take place 
principally when the diseased part remains exposed to the action 
of irritating substances, and relapses are prevented by protecting 
the part from the effects of these occasional causes. 
II .—Pathological Anatomy .—It is an inflammation of the very 
abundant sub-cutaneous cellular tissue of the region, spreading 
from a starting point; the inflamed tissues are mortified and 
become gangrenous, and by a process of suppuration, the economy 
attempts to eliminate them. The slough represents more particu-
