used. The wound was very soon completely healed, and the 
animal has never experienced any relapse. 
He intends to try the effect of this drug, which has already 
been found to be so valuable in human medicine, as a remedy 
for the foot-rot in sheep; and from what he has already seen of 
it, he confidently anticipates the most favourable results.

CASE OF RUPTURE OF THE LEFT CORONARY 
ARTERY IN A HORSE. 
% H ERR Borgman, of Hirschberg. 
On the 18th of June 1833, a levy of horses was made in 
Hirschberg, for the remount of the second squadron of the seventh 
provincial cavalry regiment. In order that these horses might be 
carefully examined as to their soundness and fitness for service, 
they were ridden rapidly in the streets. One of them slipped up, 
and came suddenly and violently on his side. He, however, 
immediately got up, to all appearance uninjured, and afterwards 
ate his food with avidity. 
When the examination had taken place, the commander of the 
troop left all the horses together, to be fed and shod ; and, this 
being done, each under officer was quartered on some neigh¬ 
bouring villa 2 :e, and ordered to set out with his men. One of 
these, who had left his own horse in the suburbs in order to be 
shod, mounted the one that had fallen down in the morning. 
The animal appeared quite calm and tractable; but just as the 
officer gave the word of command to march, it, without any 
apparent cause, leaped so high that it nearly sprang into the 
shop-window of a neighbouring house, and then fell back on the 
ground and died immediately. 
He was not opened until the next day. After the most care¬ 
ful examination of the stomach and intestines, I could find 
nothing abnormal; but on opening the chest, the pericardium 
appeared to be very much distended, and of a blue colour. On 
cutting into it, I found between it and the heart a mass of coa¬ 
gulated blood, weighing nearly 41h. 
It is my opinion that, in consequence of this mass of blood, 
the heart could no longer beat, and the circulation of blood being 
necessarily stopped, this caused the death of the animal. The 
cause of this coagulated blood I found to be a rupture of the 
left coronary artery ; and the cause of this rupture was doubt¬ 
less the fall he had in the morning. It appears to me most pro-
