And now this process, which at first had very muchthe appearance of a section of tubular gland, has taken ON EXTRACTION OF THE TEETH, ETC. a shape more like that of a Florence flask, having theglobe part filled with cells ; this is termed the enamelorgan (Fig. 6). At this time the dental germ or bulb(called by some dental papilla) makes its appearancein the tissue immediately below the bulbous expansionof the enamel organ, and by its upward growth causesan invagination of the enamel organ (Fig, 7). This enamel organ, which now rests on the dentalbulb as a double cap or hood, is composed of an outerand an inner epithelial layer, having between them aprotoplasmic mass and a large quantity of the epithelialcells which came down with the process. But theyhave now very much altered in appearance and ridge cells have now changed their ridge appear-ance by having been compressed at pa
