RISING FOUR TEARS.

Fig. 73. 



Rising Four Years (Figs. Yl, 72, 13). — From in front are seen tlie 

 eight adult incisors ; the pinchers in contact with the opposite ones, and 

 intermediate teeth not 3'et out to the level of the pinchers. In profile, 

 this is also seen in this mouth. The corner teeth are very much worn ; 

 the tables of the pinchers are considerably worn, making almost a com- 

 plete separation of the central, or cup, enamel from the peripheral 

 enamel. This advanced wear of the pincher teeth is not in direct 

 harmony with the amount of use of the corner teeth.
