struction, low down, as I did before. I then took a gallon of 
blood from her, and gave a purging drink, so as to get rid of any 
inflammation or swelling in the oesophagus. I also gave strict 
orders for her not to have any thing that day but gruel, and also 
to be particular for a few days in dieting. The drink operated 
well, and she has not had another attack, although fed on turnips.

Some time ago I was sent for to a cow that had inflammation 
of the lungs, and which was, no doubt, brought on in consequence 
of having been choaked for several days with a turnip, and she 
died of it. 
ON THE EPIZOOTIC DISEASES IN HORSES, 
CATTLE, &c. 
In page 769 of the 12th volume of this Journal, we inserted an 
Obituary ofHurtrel D’Arboval, author of the Dictionary of Vete- 
rinary Medicine, and Surgery. There is one subject which, at 
the present moment, is more than usually interesting to us — the 
cause, nature, and treatment of epizootic disease in our domesti- 
cated animals. We have — thanks to the kindness of many of 
our friends ! — sufficient to put us in possession of the opinions 
and practice of the greater part of our own brethren : it will be 
not a little important to become acquainted with that which is 
thought and done on the other side of the channel. M. Hurtrel 
d’Arboval had paid more than usual attention to this subject, and 
his treatise in the second edition is nearly double the length of 
that in the first. He thus commences his remarks. 
“ A profound study of epizootic disease is, perhaps, the most 
important branch of veterinary study and practice. These diseases, 
which occasionally destroy, in a short space of time, great mul- 
titudes of useful animals, are the more dangerous and fearful, 
because we know but little of their real nature, and the means 
by which they may be prevented. Their causes, obscure and 
concealed — their march insidious, yet rapid — fearful, and yet de- 
ceitful in their symptoms — murderous in their effects, they over- 
come a great number of victims, before their existence or their 
nature is for a moment suspected. In fact, they who first dis- 
cover them are almost always ignorant persons, who see nothing- 
in the malady of their cattle but the effect of some vulgar thing, 
which they think can be easily removed, and in the death of the 
animal, only a local and individual loss, with which those around
