    APPLYING LIGATURES. Fi^. 16^. A 11 One of these (fig. 16), intended for tying vessels which are ruptured at the side, consists of a small straight stem of steel about 2-|- inches long, sup- ported on a handle somewhat longer. It is terminated above by a transverse piece (A) resembling the branches of an obtuse Y, and each of these about -J inch long is slit deeply into two parts, between which is placed a small and very moveable pulley. The head of this instrument is a little bent, so that the plane of the two pulleys forms an angle of about 25° with the stem ; and from the outer arm of each pulley a small and slightly curved piece projects, turned at the end towards its feUow on the other side, so that a groove is formed by each of these projections, which is directed parallel to the stem. In using the above instrument the ligature (D E) is passed in the usual w^ay beneath the vessel, and the first turn of the knot made ; the two ends of the thread are held tightly together between the thumb and index finger of the left hand, and the head of the instrument being next placed between them, they are made to slide over the pulleys, the lateral projections passing over them, so as to prevent their slipping off the former ; and in this position the turn of the ligature is pushed to- wards the vessel which is thus closed, as tightly as may be wished. A second and third turn being made, the knot is completed.
