![the nodulated structure is shown, to a very con- siderable extent, in the midst of a mass of transparent secondary dentine. In this case, I imagine, from the absence of all other causes, the stimulus to have been caries : in the early progress of the disease, the secondary tissue was developed as a transparent structure, but as the disease increased, the stimulus became greater, and ter- minated in a mass of nodular structure. That this was the ultimate point of development I think is demonstrable from the circumstance that there are two examples in this tooth, and in both the dentinal tubes radiate from the nodulated structure (Plate 11, Figs. ]9 and 20). 38. Nodulated Dentine the Result of Abnormal Activity of Development.—It appears to me that this nodulated appearance under the circumstances just related throws considerable light upon the pre- sence of the nodulated or areolar form in primary dentine. This structure in dentine is invariably connected with abnormal action, which I think we may now justly infer to be the result of an over- active development, arising probably from some constitutional disturbance. This appears to receive corroboration from the circumstance that thehoney- comb teeth in which this abnormal appearance is most prevalent are generally erupted at an earlier age than the more normally developed organs. 39. Dentine less liable to Variations than Enamel. Dentine is less liable to many variations of o](https://iiif.wellcomecollection.org/image/b28093227_0033.jp2/full/800%2C/0/default.jpg)
