    14. —Another form of ditto, the conductor and canula not shown. 15. —Extremity of Civiales’ forceps for extracting calculi from the urethra; through it passes a stylet for altering the position of the calculus if necessary. 16. —Tanchou’s conical swollen scarificator, being a silver canula swollen at c, (for sheathing the four blades a, when passing through the urethra,) beyond which it tapers to a point ; four clefts cut in this por¬ tion, allow the blades to act on the stricture, the incision gradually deepening as they are advanced by the stylet b. 17-—Amussat’s instrument for breaking and extracting calculi from the urethra; through a straight canula pass three jointed steel rods united at the extremity, each of which is straightened or relaxed sepa¬ rately by elevating or depressing the arms a a a. A stylet regulates the position of the calculus. 18. —Segalas’s silver (stylet uretro cystique), which the operator should have of various dimensions for measuring the length and depth of strictures. 19. —Extremity of Amussat’s hook for removing calculi from the urethra. 20. —Civiale’s (uretrotome), being a bistouri cache, for cutting stric¬ tures near the glans penis, or removing calculi imbedded in the urethra, similar to one invented by Segalas. By a screw acting on the end of a sliding spring, the depth of the incision is regulated. 21. —The extremity of Dubouchet’s porte caustique. The caustic reservoir and canula are each open on two sides, allowing the double application of the caustic at the same time, whilst the smallest rotation of the stylet serves to sheath it. 22. —Leroy d’Etiolle’s, curette articule, for removing urethral cal¬ culi : the wire b b, passing through the tube a, depresses or raises the curette d by turning the handle of the screw c, working in the tube a. 23. —Amussat’s sonde a conducteur being a small silver catheter, in the end of which is screwed the stylet b, seen in position at c, so replacing it by a flexible catheter if required. 24. —Segalas’s forceps for extracting foreign bodies from the blad¬ der or urethra : the two bites a b, are closed by the action of the fly- screw c on the canula. 25. —Jules Cloquet’s instrument for removing hard bodies from the urethra or meatus auditorius. The wire is attached to the end of a screw working in the tube a «, and tightened by a fly screw as in Fig. 24. 26. —Leroy’s pince a trois branches for removing broken fragments of instruments, &cu, from the bladder, having a blunt pointed stylet to alter the position of the bodies in the bites if necessary. 27. —Ducamp’s urethra dilator, being a small pouch of cat-gut fixed on the end of a small silver canula, and supported by a stylet passing through it. When inserted in the stricture, it is inflated through the tube with stopcock a, 28. —Tanchou’s ditto, composed of a fine steel canula divided at its further end into eight or ten longitudinal sections, which, united to the point of the stylet a a, are dilated on approximating the ends of the tube by the action of the screw b. 29. —Vergne and Peruning’s dilator, composed of a silver canula, containing an elastic metallic dilator divided longitudinally into four portions, which is guided into the stricture by a fine wire conductor a a.
