To Mosher, ofBoston (), I am especially indebted, and would refer you tohis excellent monograph, The Applied Anatomy and Intra-nasalSurgery of the Ethmoidal Labyrinth, Laryngoscope, September,1913. The superficial features of the outer wall of the nasal fossa are. ? ???/ Fig. 1.—A. Posterior cut end of middle turbinal. b. Ethmoidal bulla, c. Unci-nate process of ethmoid. i>. Frontal sinus. e. Opening of an anteriorethmoidal cell. f. Openingof ethmoidal bulla. G. Extension of left sphenoidalsinus behind right sinus. (From specimen dissected by author.) familiar to you all, viz. the superior, middle and inferior turbinalbodies. If the middle turbiual is removed, two structures immediatelycall for notice (Fig. 1). (1) The ethmoidal huJla, the largest of the auterior ethmoidcells. Its lower convex border lies in the concavity of the hiatussemilunaris.

The hiatus is the communication between the middle meatusand the ^infundibulum. The^ infundibulum is the curved gutter-like channel on theouter wall of the middle meat
