    «c CLEFT PALATE. GrENTLBMEN,—I ppoposG to take as the subject of this lecture the conditions of imperfect development of the septum between the mouth and naso-pharynx^ comprised under the term cleft palate. In order to place their treatment on a scientific basis^ I will first call your attention to the physiology of the nosGj which practically means to a considera- tion of the mechanical factors that determine the form of the nasal cavities and of the upper part of the pharynx, described together as the naso- pharynx/' We shall then be in a position to formu- late general principles on which our methods of treatment may be most advantageously based. The chief function of the naso-pharynx is to transmit air into the lungs, in order that the sensi- tive surface of its mucous covering may become affected by substances contained in it. In other words, this part of the body is constructed essentially for the purpose of smell, and in the several groups of animals the degree of its development varies with the importance of the sense of smell to them. The upper portion of the nasal cavities is used for the ramifications of the olfactory nerve, and the current of air is distributed especially over this area by the act of sniffing. During the normal process of respiration the mouth is kept shut, the upper lip covering the upper incisor teeth entirely, and
