 the horns or nose. Close the wound as in a.

Objects. The control of hemorrhage from wounds or 

 the prevention of hemorrhage during the removal of tumors

Technic. The operation is possible on the standing

 and anaesthetize. 



The operation is made at the same point as for phlebotomy 

 and the same cutaneous wound, a, Plate XII, may be used 

 for this purpose. The incision should be at least 10 cm. 

 long extending through the skin, fleshy panniculus and
