The former has been named the tooth papilla, the latter the enamel germ. From place to place, springing up from the depths of the tissue of the jaw, convex papillar structures, the so-called tooth germs (/), grow towards the enamel germ. Here and there, increasing in diameter, they press in the under surface.
