APTHA, OR THRUSH IN THE HORSE. 
tricle of the heart was filled witli black blood, not coagulated, 
and resembling liquid pitch. The right ventricle was occupied 
by an albuminous coagulum, of a yellow colour, and which 
filled the whole of the cavity. 
There was no direct communication between the wound on the 
side and the interior of the chest. 
To these cases, in which the horse was the patient, I could 
add five others that very much resembled them. In three of 
them the animals were destroyed on account of fistula in the 
poll or withers, deemed incurable ; the fourth died from the con¬ 
sequences of thrombus, which had been suppurating nearly 
three months; the fifth was a horse that had been operated 
upon for sarcocele, and that died after twenty-two days’ abundant 
suppuration. 
On examining them after death, the blood was found in every 
one of them small in qnantitif and not coagulated in the left 
cavities of the heart, but forming dense masses of ivkite coagulum, 
distinctli/ united to a blade coagulum much less abundant^ and 
reflecting a greoi tint at the point of the junction of the two clots, 
and which, in many subjects, were prolonged, and also reunited, 
and yet distinct in the large veins running into the right auricle. 
In the lungs of all of the five horses I found little ecchymoses 
disseminated in greater or less numbers through the pulmonary 
tissues; little masses of concrete pus of a caseous consistence, 
varying in bulk from the head of a pin to that of a large filberd ; 
—some of them surrounded bv a red areola, a sort of ecchv- 
rnosis of a colour somewhat deep; others circumscribed by pul¬ 
monary tissue, yet crepitating, but evidently already infiltred with 
matter similar to that which constituted the central depot, and 
without the slightest trace of ecchymosis. 
I will add, that among the horses that have been treated for 
fistulous withers and poll-evil, in the hospital at Alfort, within the 
last two years, IM. Delafond and myself have remarked that the 
greater part have coughed during the early period of the suppu¬ 
ration, and before the pus had become thick and of a good cha¬ 
racter ; and that in some of them the cough was so violent as to 
render it necessary to employ bleedings, fumigations, and seda¬ 
tive medicines.
