ends of the arcades, with the closed molar trimmers, but 

 only when the projections are long enough to warrant their 

 use. The first superior molar and the sixth inferior alone 

 require this treatment, in the normal mouth. 



The remainder of the operation — the floating and filing — 

 is performed as follows: 



1st. Float the posterior two-thirds of the right superior 

 arcade, with the straight float, the anterior one-third with 

 the angular float, and then blunt the anterior end of the first 

 molar with the twelve-inch file. 



2nd. Observe the same routine on the left superior ar- 

 cade.

Each. 



3rd. Float the entire left inferior arcade with the 

 straight float, and bevel smoothly the anterior end of the 

 first molar with the twelve-inch file. 



4th. Observe the same routine on the right inferior ar- 

 cade. 



5th. Extract wolf teeth, if any exist, and complete the 

 operation by blunting any sharp projection, on the superior 

 molar, that may exist behind them, and which could not have 

 been reached prior to their extraction. 



It will be observed that in the above routine the arcades 

 beginning with the right superior, are dressed consecutively. 

 The work on each one is completed before passing to the 

 next, until all four have been perfectly attended to. The
