The first is in consequence of the divergence of the enamel columns from each other as they proceed towards the periphery of the tooth, and the second is pro- bably dependent upon the development of new enamel columns. But it is highly probable that in enamel under such conditions the lateral union between the walls of the several columns is never so perfect as in a well-developed organ. 16. It is more than probable that whenever there exists a condition sufficiently strong to interfere with the normal development of either of the dentinal tissues, the influence as much affects the arrangement of the salts as it does the growth of the gelatinous tissues. 17. Plan of Arrangement of the Salts within the Enamel Fibres.—The minuteness of the material with which enamel sheaths are filled must con- siderably impede the accuracy of observation, but I am inclined to think that the section from which Plate 5, Fig. 10, is made may throw some light upon the subject. With the aid of one of the higher powers of the microscope, those enamel columns that have been cut in horizontal or oblique sections are seen to have the contents of each column arranged in layers corresponding with the circumference of the enamel sheath.* * The author thinks it but right to state that his friend Mr. Chas. Stewart, on whose opinion he has great reliance, thinks that these B 2
