Nineteen Years (Figs. 116, 117, 118). — From in front the sii]iei-ior 

 corner teeth point distinct]}' toward tlie median line; tlie intermediate 

 teeth commence to incline in the same direction, showing a, marked tri- 

 angular space between them at the line of the gums. In profile, the 

 ogive formed by the apposition of the jaws is more closed. The notch 

 still remains in the superior corner teeth, but is less marked in this age 

 from the increased horizoutal position of the inferior corner teeth. The 

 tables of the pinchers and the intermediate inferior teeth seem to con- 

 A'erge at their posterior border, on account of their diverging in front; 

 their antero-posterior diameters have become greater. The inferior cor- 

 ner teeth are always triangular in the upper jaw ; the jiincher teeth are 

 usually leveled, although the cups sometimes remain in them for severnl 

 years more.
