    uniformly of the same diameter at the outer as at the inner surface of the tissue, and passes, normally, in an imperfectly spiral condition, from the dentine to the surface of the enamel (Plate 2, Fig. 3, and Plate 4, Fig. 6). In the fulfilment of this plan it must necessarily follow that since the external surface of the enamel is greater than that of the surface of the dentine on which it rests, there must be some mode by which the number of these columns is increased, since otherwise there would be an increasing interspace between every column, upon its approaching the periphery of the tooth. How these interstitial columns have been produced has hitherto not been ascertained. Some time since, having a young monkey for the purpose of dissection, I embraced the opportunity of examining the development of the dental tissues. Without looking for anything particular, I observed that some of the enamel columns were, towards their growing extremity, occupied by single nucleated bodies, but that others had two placed side by side, enlarging therefore the diameter of the enamel, and producing a forked division (as shown in the accompanying drawing, which was made with the assistance of a camera lucida) (Fig. 7). Thus each column that contains a double nucleated Fig. 7.
