Professor Porter proposed and performed the operations of tying the femoral artery for aneurism of this vessel, by making a transverse incision through the integuments, and so reaching the artery whilst enclosed within the funnel, and of course before it had given origin to the profunda: the operation was successful. Mr. Butcher performed Mr. Porter's operation in Mercer's Hospital, in the case of a wound of the profunda femoral artery. The patient sunk from loss of blood in twenty-four hours after the infliction of the wound.* Mr. George Porter and Mr. Smyly have also tied the artery according to Mr. Porter's method, in the Meath Hospital, for aneurism, with complete success. The femoral artery has been tied before the giving off of the profunda for hemorrhage after amputation of the thigh.
