Fig. 264. — Tables uf incisors (nai. size) 



From Figs. 



262, 263 and 264, we see that in old age, the chief 

 alterations in the incisor teeth consist in increased length of 

 their cro^ATis and decreased width of their necks and tables. The 

 curve formed by the tables of the incisors does not become flatter 

 after, say, 14 years.
