Five Months (Figs. 4t, 48, 49). — The jaws are thicker and the in- 

 cisive arch is wider transversely. From in front the intermediate teeth 

 are seen almost entirely free. In profile these teeth are in contact by 

 the whole extent of their anterior border ; the table of the pinchers are 

 more worn, especially above. In each jaw the anterior border of the 

 intermediate teeth is worn almost for its whole length ; the posterior 

 border is less worn. Below is seen, under the mncous membrane, the 

 internal edge of the corner teeth, which are preparing to pierce through. 

 They form a little elevation of the mucous membranes placed imme- 

 diately behind the internal border of the corresponding intermediate 

 teeth.
