In the above engraving the teeth are seen to be 

 ranged almost in a line, vv^hich is the form they have 

 a disposition to take at this great age. The appear- 

 ance, here delineated, is more true than the foregoing 

 in its general character, the infundibula being entirely 

 worn out ; for the specks in the centre of the tables 

 show, not the remains of the last portion of the 

 marks, but the exposure of the upper extremity of 

 what once was the cavity of the pulp. In the next 

 wood-cut, however, which depicts the tables of the 

 teeth which were in the jaw of a horse, that had 

 reached its thirtieth year, and from which the draw- 

 ing for the coloured engraving was made, displays 

 a portion of the infundibulum still retained in the 

 corner incisor. The true character of age neverthe- 

 less is conspicuous in the form of the tables.
