CASE OF MELANOSIS. 
By Andrew Cunningham, Y.S. 
A grey horse belonging to Mr. Alexander R , farmer, 
was sent to me, in August last, for examination, owing to the 
existence of a large swelling whichinvolved the sheath, scrotum, 
inside of the thigh, and posterior portion of the abdominal 
muscles. I learned that this enlargement of these parts had 
been noticed as gradually coming on for several weeks. 1 pro- 
nounced it to be a melanotic tumour; and gave my opinion that 
nothing short of an operation was of any avail in cases of me- 
lanosis, but that this could not be undertaken with any pros- 
pect of success in such an instance as the present. The owner 
fully coincided with this opinion, and as the horse was quite 
able to do his work, he determined to keep him on. I saw 
the horse repeatedly afterwards, and observed the tumour 
to be enlarging, and the animal to be falling away in 
condition. I also remarked that he inclined to one side in 
his walk. He gradually continued to get worse until the 
month of November, when I was again requested to visit him. 
On arriving, I found him sitting on his haunches, like 
a dog, seemingly healthy, but paralysed in the hind ex- 
tremities, especially the left. We attempted to put him 
on his feet, but, as was to be expected, failed in doing 
this. I could but consider it a hopeless case, and declined 
the adoption of any treatment. He was quite unable to void 
his urine, and had but little power over the rectum. I feared 
from these symptoms that there were other tumours pressing 
on the spine or some of the nerves coming from it. Two days 
afterwards, I was informed of his death, and was requested 
to make a post-mortem examination. I found a tumour at- 
tached to the inner surface of the ensiform cartilage, and 
weighing no less than four pounds; another adhering to the 
left kidney weighing ten pounds ; a third connected to the 
inferior surfaces and transverse processes of the lumbar 
vertebrae, also on the left side, weighing six pounds. A fourth 
weighing seven pounds involved the bodies, superior surfaces, 
and transverse processes, of the same vertebrae, firmly ad-
