Seventeen Years (Figs. 113, 114, 115). — In front, tlie superior cor- 

 ner teeth incline toward the centre. The line of apposition of the teeth 

 is very oblique on the horizontal line. To see the inferior teeth dis- 

 tinctly', the head must be well lifted. The tables of the inferior teeth 

 are all triangular ; the dental star is in the centre and distinctly round. 

 The inferior incisive arch is narrow, onl}' slightlj^ convex, and the teeth 

 appear more separated from each other than at any previous period ; the 

 ])inchers especiall}' are separated from each other in the median line. 

 The tables of the superior teeth are triangular; the cups of the pinchers 

 have nearly disappeared.
