    made up of the posterior rim of the vomer, covered by mucous membrane On cither side of the septum, two cavities are seen, the nasal fossa;. They connect the anterior and posterior nares through the medium of the inferior and middle meatuses. The parts constituting the lateral portions of the picture are: the orifices of the Eustachian tubes, the superior middle and inferior turbinated bones, and the superior middle and inferior meatuses. The orifices of the Eustachian tubes occupy the extreme right and left of the picture and look like puckering apertures in small elevated ridges of mucous membrane. The turbinated bones are the three ridges situated one above the other and sepa- rated by three corresponding spaces, the meatuses. The mucous membrane of the posterior nasal cavity, which is continuous with that of the anterior cavi- ties, is supplied with an immense number of small glands. These are of two kinds, conglomerate and follicular. The follicular glands are more abundant at the lower part of the vault of the pharynx. They arc bundled together in a glandular mass, to which the appellation of pharyngeal tonsil has been given. The conglomerate glands are more abundant be- hind the eminences containing the orifices of the Eustachian tubes and on the superior surface of the velum.
