The fascia is divided in a similar manner. The tissues beneath the fasciaare gentlv separated by the fingers or handle of the scalpel, using the cutting. edge only when necessary, until the sheath of the vessel is reached. Thenearer the approach to the vessel the shorter should be the line of the sepa-ration of the tissues, so that when the vessel is reached the outline of thewound will resemble somewhat an inverted triangle, with its apex corre-sponding to the sheath of the artery (Fig. 170). When the sheath is reacheda small opening is made into it—about one fourth of an inch being ample—of sufficient size to pass the needle with ease. This opening is made by pick-ing up the sheath or condensed tissue with the thumb forceps, carefullycutting from it a buttonhole-shaped piece of a suitable size (Fig. 171). The borders of the opening in the sheath are then separately raised, toenable the operator to ascertain if deeper tissues still surround the vessel;if so, the}^, too, should be incised in a similar manner. When the peculiarpinkish-white appearance of the coats of the artery are seen, the side of the cut in the sheath nearest to
