 tc7np.ora7'y^ jnilk, or foal teeth, and pernianettt^ or /lorse teeth.

 Front and back views of permanent incisor. 



The temporary tooth is small and white, has a distinct 7ieck, and a 

 short fang, which practically disappears as the tooth gets older from the 

 pressure of the growing permanent tooth beneath, until its remnant is 

 pushed out of the jaw (fig. 3). 



The permanent tooth is larger, stronger, and browner in colour, has 

 no marked ?ietk and a long, stout fang (fig. 4).
