Three Years Off (Figs. 68, 69, VO).— From in front the four per- 

 manent pincher teeth are seen, much larger and stronger than the 

 neighboring teeth. The anterior borders of the superior pinchers are 

 oblique, and their external borders are not yet in contact with the cor- 

 responding part of the inferior teeth. In profile, the intermediate teeth 

 are seen much used ; the corner teeth are short, and show the constric- 

 tion at their neck. The tables are worn off level. Between the corner 

 and the intermediate teeth on the left is seen the protrusion of gum 

 made by the permanent intermediate tooth which is shortly to appear. 

 The dental tables of the inferior intermediate teeth are very much worn, 

 the superior teeth somewhat less so. The inferior corner teeth are 

 entirely leveled. In this mouth the tables of the inferior pincher teeth 

 are the most worn, as these teeth came out before the superior ones did.
