K,g 



-Side view of I he incisor teeth of a crib-biter, 30 years old {same 

 as shown in Fig. 147). 



Ill tliu inoutli shown in Figs. 147, li8, and 149 (pp. 555, 557, 

 and 659), the chief indication of advanced senility is the gieat 

 acuteness of the angle formed by the comer incisor teeth (Fig. 

 Ii7). In this case, the lower tush has kept its usual length. Both 

 tushes in Fig. 267 (p. 808) are well worn down. The near side 

 lower tush in Fig. 274 (p. 813) is also in good preservation.
