TUMOUR TAKEN FROM THE BACK OF A MARE. 
he was cutting the head off, a quantity of fluid gushed out; 
the lungs were healthy in structure, but the pleura pul- 
monalis looked much like the skin ; the intestines were 
healthy, but the spleen was very much enlarged; the liver also, 
and of a clay colour; the pericardium and the diaphragm 
participated in the disease.

known and easily recognised, that we have not thought it 
necessary to have Mr. Santy’s sketch engraved, &c.; for

TUMOUR TAKEN FROM THE BACK OF A MARE. 
By G. Longman, M.R.C.Y.S., Y.S. 9th Lancers, Brighton. 
M y dear Sir, —I have sent you Cf per rail” to-day appa¬ 
rently an ossific tumour, taken by me from the back of an 
officer’s charger. It was situated on the side of the back, 
about six inches from the spinous processes of the dorsal 
vertebrae, and about opposite to the fourteenth rib. It was 
immediately beneath the skin, imbedded in cellular tissue, 
quite loose, and had no connection either with the skin, bone, 
muscles, or fascia. It was easily removed by a crucial 
incision being made through the skin, when with very little 
force it came out, almost in the same state as I send it to 
you. 
On making an incision into it after its removal, which I 
did with difficulty, I perceived it to consist mostly of what 
appeared to me to be bony matter, with a little fibro-cartilage ; 
and as I never remember seeing so large a deposit unless in 
connection with bone, I thought it worth sending to you, 
and shall be pleased to have your opinion on it. 
The history of the case is as follows :—The subject of 
the tumour is a brown mare, six years old, and ridden as a 
charger. About twelve months since she had first a slightly 
galled back, from which she recovered after having been 
blistered, and was then sent to work. When I saw it, in 
December last, the tumour was about the size of a small pea. 
I ordered a mild application of iodine, and then sent her 
to work, to be ridden regularly. In February there was still 
a slight thickening beneath the skin, and the animal was then 
worked both as a hack and charger, as she did not seem to 
suffer the slightest inconvenience from this tumour. About
