626 A SCIRRHOUS TUMOUR ON THE RADIUS. 
tirpation of it. I gave it as my opinion that the chances were 
much in favour of the dog ; but that some danger would attend 
it from the magnitude of the tumour and its close adherence. 
September 17th . — It is now dreadfully ulcerated, and the 
stench is almost unsupportable. It was determined to proceed 
to the operation. A strong physic ball was administered. 
19^. — I applied the tourniquet above the elbow. After having 
made an incision through the integuments, nearly round the 
tumour, I began at the lower part of it, and, for half-an-inch, was 
obliged to cut through the base of the tumour, almost as hard as 
cartilage. I then arrived at its close adhesion to the anterior part 
of the fore-arm. 
The cellular substance was very thin, not a line in thickness. 
I very carefully dissected along it, leaving a beautifully smooth 
and glossy surface below the tumour along its whole base, until I 
arrived at the bending of the arm, where, coming close on the 
tourniquet, I left a very small portion of the tumour, or rather a 
substance of a kernelly feeling connected with it. I could not 
remove this while the tourniquet was on. On loosening the tour- 
niquet, I took up two principal vessels, and found the skin would 
not reach over the arm, for the whole of it was diseased, and the 
smallest portion could not be saved. A wound also was left, ex- 
tending from the wrist to the elbow, three inches wide. I dressed 
with dry lint, and placed a bandage over it. 
The smooth glossy surface of the base of the tumour was not 
touched by the knife except for the first half-inch, and the clean 
glossy appearance of the fasciae of the muscles of the fore arm were 
very beautiful. The operation lasted about twenty minutes. The 
tumour, when detached, weighed twenty-four ounces, and not 
more than three ounces of blood were lost. The dog walked back 
to his kennel, and ate well in the early part of the afternoon. 
2lst . — Good matter is already plentifully forming. There is no 
appearance of inflammation, and the dog is evidently more at his 
ease than before the operation. 
2 6th . — The wound looks clean and healthy ; but there is no 
disposition to heal or contract ; it is evidently painful, as the 
dog is frequently looking at it, and begins to get ill-tempered 
when meddled with. 
October 3d . — The wound appears to be healing fast. 
10th . — Two small tumours have appeared for two or three days 
past, — one under the part of the wound that had begun to skin 
over, and where the tumour had been cleanly and completely re- 
moved ; the other under a part that was still sore, and whence, 
likewise, the tumour had been perfectly removed. These tumours 
are rapidly increasing.
