The scis-sors should be passed along it, and adjusted by the finger tips to aposition in which the axis of its point is perpendicular to the por-tion of the skull against which it impinges, or is directed slightlytoward the hand, the latter position being the better, becausem the event of its slipping it might then be arrested by the fin-gers, instead of burying itself in the vaginal wall or uterus.
