PLATE I. A DISSECTION TO SHOW THE ANATOMICAL RELATIONS OF THE INTERIOR OF THE NOSE, RHINO-PHARYNX, PHARYNX, AND THE VARIOUS STRUCTURES ENTERING INTO THEIR FORMATION. A vertical mesial section has been made, and the septum nasi (1) cut and raised to show the structures on the outer wall of the nose, the posterior margin of the septum nasi (2) being left in situ to show its relations to the Eustachian tube, etc.; (3) the superior, (4) the middle, (5) the inferior turbinated bodies, collapsed and shrunken, beneath which are respectively the superior, middle, and inferior meatuses. The left sphenoidal sinus has been broken into and a bristle passed through its aperture of communication with the superior meatus. More anteriorly, in the superior meatus, is seen a bristle passed into an opening into the posterior ethmoidal cells. Additional apertures are seen beneath this bristle; (6) the vestibulum nasi; (7) corresponds with the interpeduncular space, the anterior cerebral artery appears immediately in front of the figure; (8) the body of the sphenoid; in the middle meatus is seen a bristle (9) passed upwards and forwards through the hiatus semilunaris and infundibulum, to the frontal sinus; (10) is placed on the salpingo-palatine fold, the orifice of the Eustachian tube is seen, and behind it (11) the salpingo-pharyngeal fold, the fossa of Rosenmüller being above and behind the posterior lip of the Eustachian tube; (12) a bristle passed into the lower end of the nasal duct; (X) Agger nasi, and below this eminence is the atrium meatus medii.
