INFLAMMATORY (EDEMA.

mesentery. Some portion of blood had passed between the 
layers of the membrane, and diffused itself throughout, giving 
the whole of it a dark red colour. The spleen itself was 
enlarged, and in its substance w 7 ere several collections of 
effused blood. The stomach contained a small quantity of 
fluid. The small intestines were nearly empty, and con- 
tracted ; but the larger ones contained a good portion of semi- 
fluid faeces, and the faeces in the rectum were consolidated. 
The appearance of all these latter viscera w r as perfectly 
healthy, and but a very few grains of wheat were met with. 
No other morbid appearances were present, and the uterus 
was empty. 
In the Spring of 1848, this mare had a severe attack of 
influenza, with the formation of large abscesses in the 
region of the parotids; when the danger of suffocation 
appeared so imminent to the attendant veterinary surgeon, 
that he at once performed tracheotomy, and, on attempting 
to open the abscess, he accidentally wounded the superior 
branch of the left jugular vein. From this considerable 
hemorrhage took place, and subsequently the main trunk of 
the vein became obliterated. This could have had nothing to 
do with the diseased state of the spleen ; but the mare never 
recovered her embonpoint after this attack. 
It appears to me that the undue amount of pressure exer- 
cised by the distended stomach upon the diseased spleen 
was the immediate cause of all the mischief. I do not 
remember having seen an animal so painfully convulsed, and 
in this state she was the whole of the Sunday night, I am 
informed. 
[Mr. Sibbald kindly forwarded to us the diseased and 
ruptured spleen ; but he has so correctly described its appear- 
ance that we do not feel called upon to add any thing to it.] 
CASE OF INFLAMMATORY (EDEMA. 
By R. Hudson, M.R.C.Y.S., East Retford. 
My patient was a large, strong, wide-chested, three-parts 
bred blood mare, colour dark grey, the property of Mr. Peck, 
of Hayton. Late in the evening of the 30th October last, my 
immediate attendance was requested, and on looking the 
animal over and making a few inquiries of the owner, a 
respectable farmer, he informed me that she was first noticed
