Diseases of the throat and nasal passages; a guide to the diagnosis and treatment of affections of the pharynx, sophagus, trachea, larynx, and nares . children. As the epiglottis may be normallyor abnormally depressed, its position should always be determined by inspectionor palpation before any attempt is made to introduce an instrument into thelarynx. Local applications of powders are sometimes made advantageously to thegeneral surface of the supra-glottic portion of the larynx. The powder may bedeposited upon a localized surface from a brush or sponge, or may be blowninto the general cavity of the larynx in the form of a dry shower, propelledfrom the end of a curved tube, into some convenient portion of which it has CHRONIC LARYNGITIS. 493 been introduced. It may be projected by a puff of the breath, or, as is muchmore seemly, by a puff of compressed air from a reservoir, or from a rubber bulbat the end of the tube or alorjg its surface. In Rauchfuss insufflator (Fig. 112),which is the most convenient one I have used, the powder is inserted into a slot,which is then covered by a slide. The instrument is discharged by compressing.

The terminal extremity of the tube should be large,else it will become too easily clogged up, for it is almost always withdrawnmoistened with mucus from the larynx or with saliva from the mouth. In theabsence of a special instrument, the powder distributer sold by grocers andothers to propel insect-powder may be used, the terminal extremity being bentto suit. Accurate propulsion is rarely practicable, because of the difficulty ofcontrolling the distal extremity of the tube, which is almost certain to undergoslight displacement in the manipulation. Powders are sometimes much less irritating than solutions for purposes ofgeneral medication of the larynx. When too pungent or active, they must beproperly triturated with some innocuous attenuating material, as lycopo
