412 DISEASES OF THE HORSE. 
is bedewed with a clanuny sweat, and every respiration is accompanied 
with a moan. The leg soon swells to the fetlock; later this swelling 
gradually extends to the knee or hock, and in some cases reaches the 
body. As a rule, several days elapse before the disease develops a 
well-defined abscess, for, owing to the dense structure of the bones, 
ligaments, and tendons, the suppurative process is a slow one, and 
the pus is prevented from readily collecting in a mass. 
I made a post-mortem examination on a typical case of this disease, 
in which the animal had died on the fourth day after being found 
on the range slightly lame. The suffering had been intense, vet 
the only external evidences of the disease consisted in the shed- 
ding of the hoof from the right fore foot and a limited swelling 
of the leg to the knee. The sloughing of the hoof took place two 
or three hours before death, and was accompanied with but little 
suppuration and no hemorrhage. The skin from the knee to the 
foot was thickened from watery infiltration (edema), and on the 
inside quarter three holes, each about one-half inch in diameter, 
were found: All had ragged edges, while but one had gone deep 
enough to perforate the coronary band. The loose connective tissue 
beneath the skin was distended, with a gelatinous infiltration over 
the whole course of the flexor tendons and to the fetlock joint over 
the tendon in front. The soft tissues covering the coffin bone were 
loosened in patches by collections of pus which had formed beneath 
the sensitive lamine. The coffin and pastern joints were inflamed, 
as were also the coffin, navicular, and coronet bones, while the out- 
side toe of the coffin bone had become softened from suppuration 
until it readily crumbled between the fingers. The coronary band 
was largely destroyed and completely separated from the other 
tissues of the foot. The inner lateral cartilage was gangrenous, 
as was also a small spot on the extensor tendon near its point. of 
attachment on the coffin bone. Several small collections of pus were 
found deep in the connective tissue of the coronary region; along 
the course of the sesamoid ligaments; in the sheath of the flexor 
tendons; under the tendon just below the fetlock joint in front; 
and in the coffin joint. 
But all cases of tendinous quittor are by no means so complicated 
as this one was. In rare instances the swelling is slight, and after 
a few days the lameness and other symptoms subside, without any 
discharge of pus from an external opening. In most cases, how- 
ever, from one to half a dozen or more soft points arise on the 
skin of the coronet, open, and discharge slowly a thick, yellow, 
fetid, and bloody matter. In other cases the suppurative process 
is largely confined to the sensitive lamine and plantar cushion, 
when the suffering is intense until the pus finds an avenue of escape
