    jting of a silver tube, a e a, inclosing at e a wire spring /, circling ^ ee middle of the perforator c dj by means of the end of the screw ff, iiich is fixed in the hole h, working in the spiral groove round ^ lae perforator at d, the point of the perforator is advanced on turning i«e handle, about a line, when the screw slipping out of the groove, ■f Me perforator is instantly repelled by the action of the spring. ^ 8.—Dupuytren's (bouton a demeure) of silver, used to keep open we duct in cases of ranula, termed by the French grenouillette. 9. —Roux's blunt pointed staphyloraphy scissars, for forming jw edges on the cleft palate, with the view of adhesion. 10. —Hruby's palatine forceps, the dark shaded bite overlapping (ihe other, the stem of which is shorter. 11.—Colombat's speculum oris, the projections b b, and a «, Dressing on the teeth of the upper and lower jaw, and the tongue depressed by the silver plate d, the jaws are kept open by closing ,he handles. 12. —Charriere's ditto, the part b (with its tongue plate) pressing )on the lower jaw, the upper is raised by d, which is elevated by a iscrew in the extremity of c, seen better at e, and kept so by a fork/. In the event of any spasmodic action of the masseter muscles, the ^withdrawing the fork immediately allows the jaws to close. 13. —Musueux^s forceps, modified by Marjolin and Ricord. The stem of the upper hook being made to travel by means of a double rring in a deep groove in the lower fixed limb a c. 14. —Jules Cloquet's scissars for excising the tonsils; to prevent the slipping of the tonsil, a small hook is fixed on each blade, to avoid the necessity of a tenaculum, and so allow the operator to see more clearly. 15. —Roux's porte aiguille and needle b c, for staphyloraphy; |tthe needle is kept firmly in the bite c, by a travelling ring dj moved by a rod passing through the handle. 16. —Grafe's ditto with needle c, which is fixed in the bite by a sliding ring b. 17-—Another of Grafe's, preferred by Diff*enbach, who uses a needle which, held firm in the bite by an elastic catch, has no eye but is hollowed at the heel for receiving the end of a metallic thread. 18.—Colombat's ditto with needle h. The threaded heel of the needle being fixed in a, the point is applied to the posterior side ot the soft palate, and closing the forceps by pushing forward d e, t he needle is forced through the hole b, and by means of a pin which s pushed across the opening under the shoulder of the needle by I Liie slide c, the retraction of the needle is prevented. I 19.—Guyot's fix knot in staphyloraphy, composed of a tube «, f in which is a small metallic rod c, having a cleft at the further ex- tremity which is made to gape by the pressure of the projection d, IS seen at b, on the inner side of the tube, till pushed beyond its lurther opening by the handle e, when the mouth is closed by its own elasticity, and fixes firmly in the bite the noose of the ligature. /^O'—Schwerdt's staphyloraphy needle modified from tlrosu of Doniges and Lesenberg, being a curved needle, with the eye near the point, divided longitudinally, so easily freeing the Hgature by causing a separation in the two halves.
