the presence of the calculus. It was about eight inches long, 
and peculiar for the great extent of the separation of the 
peritoneum from one side of the mesentery ; which would in- 
dicate that the coats of the intestine first gave way at their 
attached edge, and between the layers of the peritoneum. Had 
this anything to do with the protracted nature and peculiarity 
of the symptoms ? The stomach was also ruptured, but we 
incline to the opinion that this occurred in the act of dying. 
Its digestive function being, at the outset of the animal’s 
illness, arrested, there would necessarily be an accumulation 
of the ingesta in it, which would take on the fermentative 
action, and cause over-distension. 
The calculus was of the kind denominated “ mixed con- 
sisting of the hairs of the oat and the ammonio-magnesian 
phosphate. It was very irregular in its form, its surface 
noduled, and weighed 12 oz. troy.]

GASTRO-CEREBRAL CONGESTION IN SHEEP. 
A few months ago, my attention was called to some 
sheep in the county Kilkenny, said to be diseased. The 
flock numbered about 300, and five or six of them had died 
rather unaccountably and suddenly. I examined them care- 
fully, and not being able to detect any abnormal symptoms, 
advised that the next sheep attacked should be forwarded 
to me immediately. In a few days, another was similarly 
attacked ; namely, with giddiness, accompanied with blind- 
ness and loss of appetite. At least, these were the only 
symptoms I could learn, as before the arrival of the animal, 
only a distance of three miles, it died in the cart which con- 
veyed it I proceeded to examine the carcase, and the result 
was as follows : The stomach and intestines much inflamed ; 
the liver much darkened in colour, and easily broken down ; 
the fourth division of the stomach contained a large quantity 
of sand, as did the small intestines also: the animal was very 
deficient in flesh. The only suggestion I could offer was, 
that the turnips upon which the sheep were being fed were 
in all probability the cause, and that they should be removed 
to other soil, and have other food allowed them. This 
advice was attended to, and not another case occurred. If 
I remember right, something of this kind happened in Eng- 
land a year or two since.
