    Forceps of various forms and sizes. It is desirable to have the blades of good length, so that the angle produced by opening them is acute rather than the reverse : a better form of wedge is thus presented to the orifice, through which the instrument and the stone have to pass. The inner surfaces of the blades should be slightly roughened ; they are sometimes lined with very thin canvas or kid leather, to afford a surer hold, and avoid any crushing of the stone itself. The extremities of the blades must not meet; an interval of about one-eighth of an inch should exist between them when the instrument is closed. It is necessary to have curved as well as straight forceps. (Useful forms are shown at figs. 12 and 13.) Fig. 12. A scoop is sometimes very useful, and succeeds in certain circumstances in removing a stone or fragments, better than the forceps (fig. 14). Fio. 14.
