B is a fine silver rod, by means of which the twine is drawnthrough the tube when it is being prepared for use; C corresponds to the inner tube of a tracheotomy ca-nula, which, instead of being continued as a tube, terminates in a bar (e), passes through the plug when insitu (i. e., in the contracted larynx) and bolts it in position. removed from the canula and the plug is drawn up from the larynx bymeans of the twine. It may be allowed to remain in the larynx for anhour or half an hour the first time, but this period may be gradually in-creased until the patient retains it for the whole Fig. 53.—Dr. Whistlers Cutting-Dilator: A is the olivary extremity of the instrument, with the bladeconcealed ; B shows the blade projecting from its sheath, when the key (A.) is pressed upon ; and C, theblade altogether removed from its covering. The Cutting-Dilator.—Dr. Whistler has invented a very ingeniouscutting-dilator, which is particularly serviceable for dividing webs ormembranous formations. ACUTE CATARRHAL LARYNGITIS. 195 This instrument consists of a pointed, olive-shaped bod\T, placed at theend of a suitably curved shank, and containing within its interior a sharpblade, which can be made to protrude by touching a little key in the up-per part of the handle. When the instrument is passed into the larynx,any existing web is put upon the stretch, and thus rendered tense for di-vision. The knife is so arranged that it can be made to cut forward toward
