 An expert can readily distinguish between an 

 upper and lower molar, also the side to which each

 external lateral surface, running perpendicular to the 

 wearing surface, with the exception of the sixth, 

 which has two grooves. The supero-internal sur- 

 face contains uneven sharp projections with well- 

 marked depressions. The supero-external surface is 

 rounded and smooth.
