The phosphates therefore would be precipitatedin an albuminous medium, and would form calcoglobuliu, the peculiarindestructible nature of which is well known. Thus the minute interstices in the enamel would eventually be filledup and protected by a highly resistant substance. THE TOOTH-PULP. The puljpa dentis, the organ occupying the central cavity-or pulp-cham-ber of a mature tooth, is the remnant of the formative organ of the den-tinal tissue, and the source of the nutrition and nerve supply of the fullyformed dentin. * Pickerill, Prevention of Dental Caries, 1912, pp. Fig. 182.—Vertical section of human enamel and Nasmyths membrane, showing the latter to be composedof what appears to be two layers of columnar epithelial cells.
