The American practitioner : a monthly journal of medicine and surgery . tion. In the introduction of the needle for carrying the thread,which is the pilot for the platinum wire, it is important thatthe operator should be able to appreciate where the point ofthe needle enters and where it is to come out. It is to beremembered that each lateral half of the soft palate is wedge-shaped, and it is in the thick part of the wedge that thisincision is to be made. One mucous surface, with its muscu-lar substratum, glides easily upon the other, and the needle,owing to this gliding, may come out too near the fissure ortoo distant from it. FIG. 10. NEEDLE. a a. Shaft, with handle, bent backwardto be out of the line of vision. b b. Thread which will in use fall belowthe hook, and be drawn through the sub-stance perforated by the point of the hookor needle d. c. Slide, with a foot-piece, having in itan orifice to receive the needle, and a slitin the orifice to allow a thread to passthrough it. d. Hook with an eye near the point. aThe thread is picked up by a Palato-Plasty. 153 To remedy this difficulty, the needle described in Fig. 10was contrived. The guard over the point makes it easy to becertain of the position of the point of the needle in entrancebehind the palate, and the pressure of the guard makes theplace of exit equally certain.

The thumb-piece of theshaft of a pick-up pin, whichseizes the thread and retainsit after the slide b b b is with-drawn from the needle.
