TWENTY-ONE YEARS. 



The front and middle incisors are broader lengthways than across ; 

 and, viewed from above downwards, appear to diverge outwards 

 from each other, in a marked manner. Owing to the lower corner 

 teeth becoming nearly horizontal, the hook-like projection which 

 was, previously, to be seen on the posterior edge of the upper corner 

 teeth, has, now, disappeared. Viewed from the front, the middle 

 and corner incisors of the upper jaw appear to converge inwards.
