    cannula employed for this purpose is best manufactured from elastic ma- terial, it should be 10 to 12 cm. in length, and have at its point a width Fig. 1.—The Sippy Dilator. [The dilator consists of a rubber bag 3 inches long and IJ- inches wide when col- lapsed. At an upper corner of the bag a firm piece of rubber tubing about 20 inches long is attached. Another piece of rubber tubing 3 inches long is secured in the center of the inside of the rubber bag. The lower end of this piece of tubing is closed; the upper end remains open and is secured air tight in the wall of the rubber bag. The tip of a whalebone bougie introduced into this compartment guides the bag into the seat of the stricture. The essential feature is a bag made of thin firm cloth which encloses the rubber bag, and limits accurately the degree of dilatation. The length of the cloth sac should be about 3 inches. Its width determines the degree of dilatation. In dilating strictures due to spasm the width of the cloth sac should be about 6 or 7 cm. for adults. Smaller sizes must be constructed for children and for dilating strictures due to malignant growths and cicatrix. The cloth sac must be uniform in width. When ready to introduce, a rubber condom is slipped on over the collapsed dilator and tied loosely about the rubber tubing and bougie. The distance of the stricture from the teeth is measured and the collapsed dilating bag guided well into it. A firm rubber bulb such as accompanies an ordinary Paquelin cautery may be used as an air-pump. The dilating force that may be applied directly to the stricture is enormous, but limited accurately by the size of the cloth sac.—Ed.] and lumen of about 5 mm. and above of about 12 mm. Such a cannula is introduced by means of a whalebone stylet with two ivory buttons; the lower button serves as an obdurator. The upper is larger, and permits
