    17-—Breton neau’s double tracheotomy canula, as used by Trous¬ seau ; (seen also at c d and e;) allowing by one canula sliding within the other, the tube to be lengthened, and so displacement prevented by any swelling of the lips of the wound. 18.—Whalebone and sponge for cleaning Fig. I/. 19—Trousseau’s instrument for separating the walls of the in¬ cision on the introduction of Fig. 17. PLATE VI. 1. —Two varieties of forceps wTith urethral hook, united in one, as used by Civiale. 2. —Cloquet’s double catheter for washing out the bladder by means of a continuous stream through it: a b are two openings on the oppo¬ site sides of the tube, which is divided longitudinally by a septum. 3. —Lallemand’s platina, sonde a cauteriser, having a fix a, for regulating the depth of the canula, and another b, the porte caustique. 4. —Extremity of Amussat’s porte caustique with its oval button and canula ; for the mode of application, see Fig. 7* 5. —Ducamp’s graduated flexible porte caustique, the stylet of which is regulated by a screw fix in the canula. 6. —Tanchou’s ditto, resembling Ducamp’s, to which he has added a small wire of platina, terminating in a ball c, and passing through the back of the caustic reservoir and its stylet, is regulated by a fix c; for measuring the depth of the stricture, and acting as a conductor to the porte caustique. 7. —Amussat’s ditto, to which Ricord has added an outer flexible canula ; the round porte caustique stylet being made to protrude nearer one side of the inner oval canula than the other ; when the stylet is turned, the projection of the button, which corresponds with the open surface of the caustic, catches on the inner edge of the stricture, thus allowing a more accurate application of it when the sheathing ca¬ nula is withdrawn from the stricture. 8. —Segalas’s porte caustique, modified from Lallemand’s in adding an outer graduated flexible canula in which are two screw fixes, one regulating the movements of the inner platina canula a a, the other that of the stylet.b. 9. 10.—Amussat’s urethra scarificator. On the stylet terminating in a semibutton, seen better at Fig. JO, is a small semi-lunar scarificator, wdflch is sheathed in a cleft on one side of the canula, the semibutton fitting into f notch in the other ; the instrument being passed into the stricture, its position is ascertained by the catching of the button on its inner edge. 11. —Jobert’s double scarificator being a graduated tube, on which is a sliding fix d, the scarificators are gradually projected by means of the stylet on which is a fix c. 12. —Tanchou’s ditto, being a graduated tube cleft in the end for receiving the scarificator a, which is slided forward along a globular¬ headed wire conductor b b, into the stricture. 13. —Segalas’s uretrotome, formed of six or eight blades, projecting from a straight canula, a globe-headed stylet passing through the cen¬ tre forms a conductor to them.
