    between them septa or partitions begin to be developed across the groove, thus providing each tooth-germ with a separate apartment—as yet, however, roofless. In this condition the tooth- germ is termed a papilla, and its containing cavity a follicle. But matters speedily become changed: the tooth-germ rapidly increases in size, and the containing cavity becomes roofed in, and now the roofed in papilla henceforth as- sumes the designation of the pulp, and the enclosing cavity the name of the sac. This sac is so wide that a space exists between it and its enclosed pulp ; but the space thus present is not empty, but is occupied by what appears as a thick transparent fluid, so that three different elements thus enter into the germinal or embry- onic condition of the tooth, viz., the Pulp, the Thick fluid surrounding it, and the Sac enclosing both,—the sac and its contents being again lodged in the substance of the jaw. And now commence those changes by which these as yet soft tissues are converted into the future tooth. The pulp takes on an action by which its soft substance is transformed into the hard material forming the body of the tooth— the material mentioned as being denominated
