Fig. 159. 



Bishoping (Figs. 157, 158, 159).— From in front the figure shows a 

 space, above the corner and intermediate teeth, made by their having 

 been filed. This is seen more plainly in profile. The tables show the 

 roughened surface left by the file, and the artificial, blackened cups, at 

 the posterior border of which are seen the real cups, surrounded by 

 enamel.
