    ILLUSTRATIONS. FIG. 1. Showing opaque striae coinciding with inequalities on the surface of the enamel. 2. Showing the convergence, at point «, of the areolar marking or nodulated dentine, with an opaque band in the enamel. This is also exemplified in Fig. 1. 3. Showing an apparent arrest or change in the development of the enamel, the points of alteration being marked by a broad opaque line (a), consisting of a mass of circular nodules, from which point the direction of the enamel fibres is changed. 4. Showing the imperfectly-united condition of the extremities of the enamel columns. (Part of No. 1 more highly magnified.) 5. Showing fissures between the fibres of enamel at the base of the tissue. 6. Also showing the tendency of the enamel columns to pass to the surface in a spiral direction. 7. Transition enamel cells, showing the mode by which they increase during development as they approach the external surface of the structure. (From a young monkey.) 8. Commencement of the deposition of enamel on dentine. (From a calf at birth.) 9. Tooth of fossil crocodile (Marmorosaurus). After Owen. 10. Showing the plan of the arrangement of the lime within the walls of the enamel column. Horizontal section. 10a. Ditto, vertical section. 11. Destruction of enamel by caries. 12. Showing the tendency of the enamel to be less perfect the nearer to the cementum. (From the tooth of an elephant.) 13. Showing the development of cementum between, and to the obliteration of, enamel in human teeth. 14. Enamel having a deep fissure filled up by noncorpusculated cementum. 15. Cementum of Fig. 14 more highly magnified. 16. Section of a decayed tooth that had been filled with cadmium, in which secondary dentine is developed. 17. Same, seen by the assistance of a two-thirds of an inch power, drawn by the aid of a camera.
