A CASE OF CARDITIS. 
19. I have not seen it a second time in the same animal. 
For several weeks the disease subsided, and it might almost 
have been said that it had disappeared ; but within the last two 
or three weeks it has been gradually spreading over the country 
again. As it was in autumn, so it is now, attacking those cattle 
first which had been at any market or fair. So convinced are 
the farmers in general that the disease is principally contracted 
at these places, that many have refused to purchase any cattle 
from the market. In almost every instance, the breaking out of 
the disease amongst the cattle on a farm can be traced clearly 
to infection. They have been either in contact with strange 
stock, or fresh cattle have been brought on the farm. A number 
of Irish and Scotch cattle is brought into this county twice in 
the year; in the autumn for the straw-yards, and in the spring 
for grazing purposes. These cattle arrive in large droves, and 
are sold to a great many farmers in small lots. The disease ge- 
nerally exists in these droves, and they are frequently obliged to 
rest for some time ; but those which have escaped, and also those 
which have recently recovered, are taken to the different markets, 
and sold. The purchaser, being quite ignorant as to their having 
had the disease so recently, takes no precaution ; and the conse- 
queuc^iswthat the infection is propagated to the rest of his stock.

A CASE OF CARDITIS. 
By Mr. S. Wheatley, V.S., Staindrop. 
Sir, — I was called on to attend a pony, suddenly taken ill on 
the 2d instant. The case being probably unusual, I make free 
to forward the following account of it. 
He was a handsome pony, upwards of sixteen years of age, 
and very fat ; in height about thirteen hands and a half, and the 
property of the Duchess of Cleveland. Her Grace’s coachman 
had given physic to this pony, as well as to the others, three days 
previously, and it had operated tolerably well. On my reaching 
the stable on the 2d inst. the pony’s heart was beating loud and 
quick, audible at some distance, and presenting, from whatever 
cause it arose, an evident case of carditis to a frightful degree. 
The coachman had, as soon as he saw the pony ill, taken away 
about three quarts of blood. The violent action of the heart in- 
duced me to open the neck vein ; but before I had subtracted
