Tlie first phases of the plienomena associatedwith breach of surface are concomitant withcellular activity; and a barrier to the bacterialincursions, composed of adventitious dentineconveniently classified as areolar, cellular, fibril-lar, hyaline, and laminar (10), is thrown up onthe pulp side as a rampart. But the con-structive do not proceed pari passu witli the less rapidly accomplished, and an entrance tothe pulp cavity is effected, in spite of the loweredphysiological resistance, and in spite of the.
