A CASE OF MELANOSIS.

process. 1 have frequently, when mischief has been threatening 
from phlebitis in the horse, arrested it by taking up the vein, 
which I have always found answer extremely well, as under that 
operation the parts below the ligature assume the nature of a 
simple wound, and the animal can safely work during its progress. 
Had I seen my patient in an earlier stage of her complaint, I 
should have resorted to the beforementioned treatment; but the 
general symptoms are so bad, that there appears no hope. When 
a termination takes place, I will, if I can, examine her, and make 
you acquainted with the result. 
A CASE OF MELANOSIS. 
A CASE of melanosis occurred in a grey mule eleven years old* 
and who had a considerable tumour in her teats. It was of an 
ovoid form, as large as an ostrich’s egg, considerably hard, and the 
skin scarcely to be penetrated. 
On the day the operation was to be performed she was more than 
usually depressed — the pulse was small and feeble — the beatings 
of the flanks tumultuous — the skin alternately cold and hot — the 
sight almost gone — and the alvine dejections few and of a cada- 
verous smell. 
On being examined, a tumour was found in the teats of more 
than a pound weight, formed of melanotic matter, softened at several 
parts, and various small white lines crossing it. There was con- 
siderable melanotic degeneracy. The posterior portion and the 
ovaries were augmented to six times their volume, surrounded, 
with melanotic granulations of a variable size. The kidneys were 
surrounded by melanotic degeneracies on a base, large or pedun- 
culated, and presented the same character as the tumour on the 
teats. At the surface of the liver were the same kind of melanotic 
tumours. On the left lobe of the lung there were more tumours 
than on the right lobe, and the tissue was of various forms. In the 
cavity of the pericardium there were about three pints of red se- 
rosity, holding in suspension some albuminous flocculi. 
The death of the animal was attributed to hydro-pericarditis.
