    Figs. 30 and 31.—These cuts are taken from the incisive region of different human foetuses, evidently not far from the sixteenth week of gestation. A detailed description of the figures would be unnecessary. The cuts are introduced here simply because they present one peculiarity that is not represented in the other figures, viz, the origin of the epi- thelial cords for the permanent incisors directly from the epithelial lamina, instead of their being offshoots from the cords of corresponding temporary follicles. These are desig- nated by the letters E on the right of the figure. Though these figures seem to establish the fact that the teeth of replacement are sometimes derived directly from the epithelial lamina, yet we must not regard these as con- clusive evidence until they are fully verified by other skill- ful histologists. For the drawings of these 1 am indebted to my friend Dr. Black. (See description, p. 137.)
