all seems fitting and sym- 

 metrical, save that the little 

 tubercular, m 1 , above has no 

 opponent in the lower jaw. 

 And, perhaps, the close ob- 

 server might notice that, 

 whilst the upper canine, c, 

 glides behind its homotype 

 below, the first upper false 

 molar, p 2, passes anterior 

 to the crown of the first false 

 molar, p 3, below ; and that 

 the second false molar, p 3, 

 and carnassial, p 4, of the 

 upper jaw are also a little 

 in advance of those teeth, 

 p 4, m 1, in the under jaw, 

 when the mouth is shut.

 upper false molar, p 1, 

 differs from the first, p 2, in

 the mouth is shut, it pre- 

 serves the same relative 

 position to its opponent 

 below, p 1, in III., which 

 the upper canine does to the 

 lower canine, and that the 

 same may be said of the 

 second and the third false 

 molars ; but that, with re-

 p 4, this tooth repeats the 

 same relative position in 

 regard to the fourth false
