This incision should be carried through skin, platysma, andsuperficial fascia, and should terminate about an inch above the head should now be brought a little forwards, so as to relax thesterno-mastoid muscle, and the cellular tissue beneath is to be raisedwith forceps and divided; but any veins that are found are to be turnedaside with the handle of the scalpel, and are not to be wounded if it canbe avoided. Next come the thin strong deep fascia and the omo-hyoideusmuscle, to the margins of which it adheres. It should be pinched upslightly with the forceps, just below that muscle, and be divided by cau-tious touches with the knife, which should be held with its flat surface Fig. towards the artery; and this division of the fascia should be made im-mediately over the artery, the situation of which is to be carefully ascer-tained with the finger. Then about half an inch of the sheath is to beopened in the same manner—avoiding the descendens noni nerve, whichramifies upon it. It should be opened rather to the inner side of theartery, so that the jugular vein may not be interfered with. Then ananeurism needle, armed with a single ligature, is to be carried round thevessel. It is to be passed from the outer side, and to be kept close tothe vessel, within its sheath. When its point appears on the inner side,the surgeon seizes the ligature with forceps, and withdraws the needle—ascertains that the nervus vagus is not included in the ligature—andthen ties it tightly in the double knot. One end of the ligature may thenbe cut off close to the knot, and the other be left hanging out of the w^ound,which is to be clos
