62 CANINE AND FELINE SURGERY. 



and washed with some antiseptic, and an incision made over 

 what is thought to be the most convenient part. Cutaneous 

 haemorrhage is arrested by the application of artery forceps 

 (for which purpose the Spencer Wells or bull-dog patterns are 

 the most convenient), and the skin carefully dissected off around 

 the growth, the latter being raised by a tumour hook or by 

 passing a needle and strong silk through it in order to make 

 a loop to take hold of 



Having kept the parts neatly cleansed with tampons of 

 aseptic cotton-wool, and taken up the vessels wherever neces- 

 sary with artery forceps, the tumour should be carefully dis- 

 sected to its base ; here, as a rule, will be found the main blood 

 supply, which needs to be secured either by a ligature or by 

 torsion in order to prevent haemorrhage. A cut with a scalpel 

 completes the removal, or if the dcraseur is to be employed, 

 the chain is now put on and tightened very slowly until ex- 

 cision is complete. The edges of the skin are trimmed and 

 sutured, a drainage tube inserted in position if considered 

 necessary, and the parts treated antiseptically as an ordinary 

 surgical wound.
