Sketches of horses' teeth, showing 1, a temporary incisor or 

 characteristic shape ; 2, a permanent incisor, broader and longer than 

 No. 1 ; 3, a permanent incisor with lines indicating the appearance 

 of the two as it is subjected to wear. At "A" the unworn surface of 

 the new tooth is shown. At "B" the mark is indicated with the general 

 shape of the table. At "C" it is noticeable that the mark becomes 

 much smaller while at "D" the triangular shape of the tooth that is 

 well worn makes its appearance; 4, shows the natural mark and table 

 of a horse's tooth. It will be noticed that there is a ring of enamel 

 around the black mark or center ; 5, this sketch shows the table of 

 the horse's tooth that has been "Bishoped" or fixed so as to bear some 

 resemblance to a young tooth with the natural mark. This black 

 mark has been made in the tooth by the use of a hard instrument.
