The introduction of the tube will befacilitated by the insertion of a close-fit-ting bougie or catheter as a guide or con-ductor. The tubes used by myself areeach provided with a well-fitting metallicconductor (Fig. 204), similar to that used tion of Uacheotomy-tubewith the cylindrical anal or vaginal speculum, composed of arigid wire, with handle, and a protruding beaked extremity,flattened from side to side, and fitting closely at each orifice,so as to be perfectly steady, and constitute a single instrument43.

The whole manipulation is so quicklydone that there is practically no suspension to rectangular tube of Mr. Durham is furnished with a coni-cal pilot-conductor, with a vertebrated or flexible body ofscale-links, like the inner tube. Dr. Krishaber! uses a hollowpilot, perforated, catheter-like, at the sides of its beaked ex-tremity, and otherwise an ordinary inner tube, which has theadvantage of not interfering at all with respiration during itsmanipulation, and which appears to be the most desirable ofall contrivances of its class. The sides of the terminal portionof the outer tube used by him are truncated, so as to give ro
