crowns are compressed, so that the tore and aft diameter much exceeds the transverse. The body of the crown is a flattenied shaft of dentine,one face of which is the denser, and produces the cutting edge. This face is flat or weakly keeled, whlie there are two other faces uniting at an open angle, thus giving a subtriangular section. On each of these faces is adherent a shaft of cementum-like material of a dense character, whose external face is lonigitudinally concave. These inclose between them on the median line a deep groove, which expands below into a wide
