Diptheria, its nature and treatment . iable. Fig. 7 represents the normal lumen of the subglotticdivision of the larynx from a child of the same age, and a section from the trachea of the same showing the greatdifference in the caliber of the air passage at these points.

Greater interferencewith deglutition and the danger of ulceration if the tube belong retained, are the only objections to this plan. All suchindications could be met by a greater variety of tubes. When the proper tube for the case to be operated on hasbeen selected, a strong thread of silk, or linen is passed throughthe small eyelet intended for this purpose, and the ends tiedtogether. Braided silk is the best, as it will not unravel if one.
