REMOVAL OF A LARGE MYXO-SARCOMA IN THE DOG—EXCE 
LENT RESULT OBTAINED BY THE USE OF COCAINE—RECOVERS 
By the Same and W. S. Gottheil, M.D. 
On the 22d of March a large pointer dog was brought to ti 
college with a large tumor situated on the right thigh. It w 
moveable, apparently soft, and doughty to the feel. It cover* 
the outside of the thigh, measuring several inches in length ai 
in width, and had been growing for some time. Having deckh 
to operate on him and remove the growth, five drops of a sol 
tion of cocaine wore injected upon five points of the circui 
ference of the tumor, and after waiting ten minutes the varioi 
steps of the operation were proceeded with. An insertion w 
made in the whole length of the tumor, measuring about tt 
inches in length, the skin dissected backwards and forwards ar 
the enuclation begun. Its borders were well defined, being ov 
and quite regular. After carefully separating it from the rnuscL 
upon which the growth lay, it was found to be connected by 
pedicle with a second tumor, smaller, laying between the bicej 
femoris and the vastus externus and extending down to tl 
posterior face of the femur. This was also enuclated. Aft* 
the complete removal, the wound was sewed up and antisept 
treatment applied. The outside growth weighed 1J- lbs.; the i 
side, ten ounces. The operation lasted about thirty minutes an 
at no time of its duration did the dog manifest any pain. Th 
local anesthesia produced by the cocaine was most excellen 
The wound, however, proved rebellious to cicatrization. Quito 
large piece of the skin sloughed away and at the time of writin 
quite a large portion of subcutaneous tissue is yet exposed an 
granulating.
