    DESCRIPTIONS OF CH ROMO-LITHOGRAPHIC PLATES. PLATE I. Fig. 1. Normal tympanic membrane of the right side. 2. Normal tympanic membrane of the left side. 3. Tympanic membrane with slight opacity. 4. Tympanic membrane depressed, with perforation in the anterior segment. 5. Inflamed membrana tympani. 6. Inflamed tympanic membrane : the inflammation subsiding. 7. Inflamed tympanic membrane at a still later stage (radial striation). 8. The same membrane ; the inflammation having disappeared. 9. Abscess involving the entire periphery of the drum-membrane. 10. The same membrane at a later stage of the inflammatory process. 11 and 12. Abscesses in the tympanic membrane, as seen directly after evacuation. 13 and 14. Perforation of the tympanic membrane as a result of inflammation. Fig. 14 shows, at the edge of the perforation, the yellowish border which denotes the commencement of cicatrisation. 15. Membrana tympani perforated and partially atrophic in consequence of inflammation. 16. Perforation with calcareous degeneration of the tympanic membrane, of which the residue is observed on the handle of the malleus and at the margin of the auditory canal. 17. Perforation with calcareous degeneration of the tympanic membrane, the residue of which is seen on the handle of the malleus and at the margin of the auditory canal. A portion of the calcified membrane is adherent to the descending process of the incus. 18. Destruction of almost the entire tympanic membrane. The handle of the malleus still present, resting on the promontory. 19. Chronic inflammation of the drum membrane, with calcareous degeneration and granu- lations. 20. Drum-membrane affected with chronic inflammation, and covered with granulations. 21—25. Cicatrices in the tympanic membrane. 26. Cicatrices exhibiting different reparative processes in the same drum-membrane: in front and above, is seen a membranous mobile cicatrix : in front and below, the margin of the perforation is adherent to the inner wall of the tympanic cavity: behind and above, is a formation of epidermis over the margin of the aperture (permanent perforation). 27. I.aige cicatrix on the anterior segment, with thickening of the posterior segment and backward displacement of the malleus.
