    closely to each other at their joint, as they are represented to do in figures 1, 2, and 4, the bolt of the handle-shank is instantly driven forward by its spring into the aperture sunk in the pro- duced end of the blade-shank, by which these different parts be- come one continuous and entire shank to the right hand counter- part of the forceps. It being exceedingly difficult, and the late Mr. Lowry assured me that it was impossible, to give a perfect idea of this instrument in a drawing; I would strongly advise surgeons’ instrument-makers to procure a model of it from the original maker, Mr. Botschan, of Worship-street, Finsbury-square. See p. 40, and p. 261. Plate II. is intended to represent the mode of introducing the left-hand blade of the common forceps, and the representation answers its purpose so completely, as totally to supersede the necessity of any further description. See p. 201, &c. &c. Plate III. represents the mode of introducing the right-hand blade. The handle may be held easily in the right hand, and in- troduced as represented in Fig. 1, or, in certain positions of the subject, as represented in Fig. 2. See p. 205, &c. &c. Plate IV. Fig. 1, represents both branches of the author’s com- mon forceps, actually introduced and adjusted at the lock. Fig. 2, is an attempt to show the progressive change of direction recom- mended to be observed in the introduction of the right-hand blade. See p. 206. Plate V. represents the easy and extremely cautious manner in which the child’s head should be withdrawn from the pelvis ; when really necessary to finish the delivery of the head by means of the forceps. See p. 209.
