    are visible, one of which communicates with the posterior eth- moidal cells, whence comes much of the secretion in old cases of post-nasal catarrh. The middle meatus also has two orifices ; one leading into the frontal sinus by the infundibulum ; the other, which is the most important, opening into the antrum. The lower meatus is the largest and presents the inferior orifice of the nasal duct. This duct, in catarrhal disease, frequently becomes blocked up Avith inspissated mucus, owing to infiltra- tion of the pituitary membrane, causing a sensation of dryness in the nostril of the side affected, and the tears accumulate in the lachrymal sac, or even flow over the lower eyelid and cheek. Fig. 1.—External Wall of the Nasal Fossa. 1, left frontal sinus; 2, sphenoidal sinus; 3, opening of the sphenoidal sinus ; 4, upper meatus ; .5, middle meatus ; 6, communication of infundibulum with left frontal sinus ; 7, lower meatus; 8, interior orifice of nasal duct ; 9, orifice of Eustachian tube. Posteriorly, the nasal fossse communicate by means of two ob- long orifices with the pharyngeal vault. On either side of this space are found the openings of the Eustachian tubes, and above and behind, the fossse of Rosenmiiller, while upon the median line, and extending to some distance laterally, as well as down- ward, is seen the mass of glandular tissue to which the name of pharyngeal tonsil is given. This region below is limited by the free margin of the soft palate. Inasmuch as from a physi- ological and pathological point of view there are numerous close rela^tions existing between the space described and the nasal chambers, properly speaking, one region cannot be wholly sep- arated from the other. The surface of the nasal mucous membrane is generally
