Four Years (Figs. 74, 75, 76). — From in front the four superior per- 

 manent teeth are seen in contact with the inferior teeth. The jaw has at- 

 tained such a width that the corner teeth are almost hidden. In profile, 

 the latter are seen to be very small. The superior ones have commenced 

 to be pushed out from the jaw. In the lower jaw are seen the tush teeth. 

 The tables of the intermediate teeth are much worn, especially in the 

 upper jaw, in which the eruption took place first. The central enamel 

 is only separated in the superior left-hand teeth ; the inferior corner 

 teeth are almost leveled, the superior ones completely so. The latter 

 are being pushed out, and show their roots.
