and which have contributed toward difguhing feme 
Operators, are avoided by this aforefaid Contrivance. 
The Inhruments that extrad the Stone touch the 
Biadder no otherwife than to lay hold of the extraneous 
Body : And, as foon as they have laid hold of it, they 
have nothing to do but with the T)ilatato-Sufpenfors t 
which are fo broad, fmooth, and well pohfhed, that 
they preferve the Bladder from any Hurt, dilate the

Having placed myfelf on the Right-hand of the 
Patient, I did the Operation in the Manner above 
deferibed, having begun by injecting the Bladder.
