as has been fhewn above, taking care to prefs clofe 
the Extremity AC upon the Stone, and to leave the 
largeft Opening on the Side of the Handle B^Dy as 
in Fig. 7. both to hinder the Stone from efcaping,

the Screw G, you leave the Screw F almoft at Li-

pen’d to Jofeph Bunel , whom I cut at Andeljs in 
1743. of which I have communicated the Obfervation 
to the Royal Society ; ° 1 ' fhajt the Stone has made

become much more eafy by the means of thefe .For* 
ceps, than by the Bullet- drawers, and moft of the 
other Inftruments invented for that Purpofe ; pro-
