OPEN JOINT IN A CART HOUSE.

Replying to my inquiries, the owner told me he had bought the 
animal, when a few weeks old, from a neighbouring crofter, the 
tendencies of whose stock to tuberculous disease I well knew. 
I soon learned she was the calf of an old cow which had 
died of tuberculous disease only a month previous to this 
time. I had no longer any doubt as the nature of the ail¬ 
ment, and intimated to Mr. Wilson that death would be au 
early result. The animal lived a week longer, but gradually 
lost power, and became completely comatose during the last 
three days. 
Death took place on the 7th of June, on which day I made 
a post-mortem examination of the carcase. To be brief, I 
may just state that the membranes of the brain were studded 
with the peculiar gritty deposit, and considerable effusion 
of fluid was observed, as in the former case. The contents 
of the chest and abdomen were free from taint, as far as the 
eye unaided could detect. I confess 1 expected to find con¬ 
siderable deposit on the pleura, more especially from 
my knowledge of the following fact:—A calf, descended 
from a healthy stock, in possession of the crofter above 
mentioned, which had been allowed for several months to 
suck the milk of the old cow referred to, presented the symp¬ 
toms of the above case in a marked degree, when only eight 
months old, being thoroughly prostrated and utterly oblivious 
to all surrounding objects during the last four days of exist¬ 
ence; and when examined by me, after death, the thoracic 
cavity was literally packed with masses of tuberculous 
matter. 
Circumstances prevented my inspection of the cranial 
cavity and spinal canal of this animal, else, no doubt, indica¬ 
tions of the disease would have been met with in these 
parts. 
OPEN JOINT IN A CART HORSE. 
By Joseph Leather, M.R.C.V.S., Liverpool. 
I beg to submit to your notice the following singular case of 
open joint associated with fracture of the bones of the knee. 
On the 20th October, 1869, I was called in to see a 
remarkably fine and valuable roan cart horse, the property of 
Messrs. Roberts and Robinson, contractors and builders in 
this town. The horse had fallen in the cart. No injury was 
done to the anterior part of the knee-joint, but a wound was
