ral Operation. Immediately after Frier Jaques , Mr. 
Ratiy who was qualified to corred the Defe&s in the 
Method of the former, invented a particular one, of

in order to cut into the Body of the Bladder, the 
grooved Staff is quite ufelefs ; and even the common 
Staff is generally of little or no Ufe, becaufe the End of
