CASES OF DIARRHCEA IN CATTLE. 
By Mr. W. A. Cartwright, Whitchurch. 
CASE f. 
I examined a yearling bull calf on the 28th May, 1831, that 
died of diarrhoea. It was a cross-bred one, and rather delicate, 
and had been ill some months with the disease. The third stomach 
was quite filled with masticated grass, and was perfectly sound. 
The plaits upon the fourth stomach were about an inch thick, 
(at least three of them were), and underneath the secreting coat 
there was contained a quantity of serum and lymph, but chiefly 
of the former, and which had the appearance of jelly. The plaits 
were very tender, and the least force would penetrate them, and 
suffer the serum to escape. Underneath the other part of the 
stomach there was similar oedema, but not to so great an extent. 
There was scarcely any food in it, and that which it contained 
was very watery. The small intestines were a little softened, and 
the secretion in them was greater than natural: the csecum had 
two or three small abscesses j ust under the inner coat, but which 
had not burst, and many places of it were marked with black 
streaks. The whole of the abdominal cavity was very white, and 
infiltrated with serum, more or less, in every part; but to a casual 
observer it would be thought to be sound, on account of its white¬ 
ness : and it contained but little more serum than usual. The 
bladder was full of water, and sound : the heart was inflamed 
about its base, and coated with lymph about the coronary vessels : 
the pericardium contained a pint of serum, and of a natural colour. 
CASE II. 
20th of June, 1831, I examined a yearling heifer calf that had 
had diarrhoea for several months. The fourth stomach was in a 
similar state to the above one, and contained a little fine sand, 
which it had been accustomed to pick up in the field. The third 
stomach was filled with soft masticated grass, and sound. The 
small intestines were filled with very liquid faeces, and they 
seemed sound : the hepatic ducts were thickened, and contained nu¬ 
merous flukes : the liver generally was of a clayey colour : the gall¬ 
bladder was very large, and contained about half a pint of gall, of 
a natural colour but rather thin. The whole of the body, gene- 
rally, was infiltrated with serum, and of a white colour. The kid¬ 
neys were sound. 
CASE 111. 
On 6th August, 1831, Mr. Moss, of Heath Lane, called on me
