points of their surface carious. The pus which had entered the 
spinal cavity had not penetrated through the spinal mem¬ 
branes. 
We exposed a part of the spinal chord, corresponding with the 
points occupied by the puriform matter. The superior columns 
were softened to the extent of three or four inches, and towards 
the hole through which the pus had penetrated into the spinal 
canal: this portion of the spinal chord was more fluid, and of a 
yellow colour. The inferior columns had the same hue, but more 
consistence. The cellular tissue surrounding the chord was 
highly injected. 
This case appears to me valuable on account of the evident 
cause of the paralysis, the eflhsion of pus into the spinal canal, a 
fact which 1 believe stands alone in the records of veterinary me¬ 
dicine. The increased sensibility is also well accounted for by 
the state in which the superior columns were found.

PATHOLOGICAL FACTS, AND OBSERVATIONS ON 
DIARRHOEA IN CATTLE. 
Bij Mr. Samuel Browne, V.S.y Melton Mowbray. 
As the diseases of neat cattle were not taught at the institu¬ 
tion from which we derived our professional instruction during 
my pupilage, it may appear presumptuous in me to address you 
on that subject; because the practical knowledge which I possess 
is not based upon any professor’s lectures on this branch of our 
art. But I am fully sensible of the utility of your Journal, and 
my object in writing is to fill a void space in its pages—not pre¬ 
suming to instruct, but hoping to amuse. 
Diarrhoea is met with in every variety of breed ; and although 
young cattle are the most subject to its attack, it occurs 
in both sexes long after the adult period. Diarrhoea is said to 
be a chronic inflammation of the mucous coat of the bowels ; 
and post-mortem examinations and some painful reflections have 
convinced me that these traces of disease in the mucous mem¬ 
brane are often either the effects of an imperfect digestion, or a 
morbid biliary secretion. In winter store cattle generally live on 
straw, or ill-got mouldy hay. This kind of food may absorb a 
smaller quantity of water, or injure the internal surface of the 
stomachs so much as to check the natural secretions. The pecu¬ 
liar structure and, perhaps, functions of the many plus may render 
it highly favourable to the accumulation of cakes of indigestible 
food between its plaits, and which become indurated to such a «
