MELANOSIS OF THE KIDNEYS IN A HEIFER. 
By Me. Andeieu. 
A Normandy heifer, two months old, was found dying without 
having ever presented signs of disease. At the post mortem, the 
cause of death was found to be due to well-characterized pulmon¬ 
ary congestion. Besides this, the left kidney is found to be of 
black color, while the right is of slate shade. The superficial 
parts of the surrounding fat, the aponeurosis of the great psoas 
muscles are of a dirty grayish color. The rumen, intestines and 
peritoneum in contact with these are also colored black. The 
coloration of these parts extends into the structure of the kid¬ 
neys and adheres to the hands which manipulates them. The 
renal capsular present the same alteration. It resembles very 
much a case of melanosis infiltration, and is rather exceptional in 
its manifestations .—Recueil de Med. Vet. 
PSORIASIS OF THE HOCK.—ABSCESS FOLLOWING.—RECOVERY. 
By Me. Bright. 
A horse had at the hock point, in front, a dilatation of the 
synovial capsule, a blood spavin. A blister was applied to it and 
followed by its removal. About two weeks later, a wound, 
solution of continuity across the hock, scratches like, made its 
appearance in the fold in the hock. Though the animal is kept 
at moderate work, a large swelling soon shows itself in the entire 
leg, which is then unable to carry any weight. Intense fever 
sets in, and a slight fluctuation shows itself at the bend of the 
hock. A few punctures give escape only to small excesses of 
blood. The hock is then treated by continued irrigation, and 
the next day, say the fifth from the appearance of the swelling, 
two incisions are made on the internal face of the hock, 
large enough to allow the escape of a dark, wine-colored pus. The 
irrigation kept up for a few days, was followed by radical cure. 
The case shows the danger of allowing an animal to work 
when suffering from solution of continuity in front of the hock, 
as well as the advantages derived by hydrotherapic treatment.
