Thus, the anterior meatus is the narrow interval between the anterior (ethmoidal) turbinated bone and the roof of the cavity (the nasal bone) ; the middle meatus is another and larger interval between the two turbinated bones; while the posterior meatus, the largest of these intervals, is included between the posterior (maxillary) turbinated bone and the floor of the cavity. The Inner Wall (the septum nasi) is partly bony, and partly cartila- ginous. In iti upper part it is formed by the bony perpendictdar plate of the ethmoid, and at its posterior edge it is formed by the vomer bone ;.
