(From a photograph.) sinus open through a small aperature situated to Zuckerkandl ( Anatomie der Nasenhole), theethmoid cells are occasionally continued into the middle, or eth-moidal, turbinated bone.

The spacebetween the inferior and middle turbinateds is know^n as themiddle meatus, into which enter the canals from the frontal sinus(the infundibulum), the anterior ethmoidal and the sphenoidalcells, and the antrum of Highmore (the latter occasionally bytwo passages). Within the middle meatus is a crescentic open-ing, the hiatus semilunaris, the upward and downward con-tinuations of which pass into the frontal cells and antrum ofHighmore, respectively. Below the inferior turbinated is the Vault of Superior meatus. Inferior palate. Mouth. Key to Fig. 2. inferior meatus, into which the nasal duct opens by a somewhatexpanded mouth, provided with a partial valve formed of mucousmembrane. A fourth bone frequently exists in close relation tothe upper turbinated; this, according to Zuckerkandl, is therule at birth, and Voltolini considered it characteristic of the As the accessory cavities are in such close relationship tothe nasal cavities, it is customary to describe these sinuses, orpneumatic chambers, in this connection. They lighten the 6 DISEASES OF THE NOSE AND THROAT. bones in which they are situated, and are supposed to affordincreased resonance to the voice.
