the upper Side of the Bladder ciofe up to the 
Integuments. Then along the Blade of the Knife 
I introduce into the Bladder the Part a of thelnftru- 
ment reprefented in Fig. 8 . and placing this very 
eafy fmooth Crotchet in the room of the Back of 
the Knife, I give it to an Affiftant to hold and keep 
up the Bladder ciofe to the Integuments. This done, 
I put the Fingers of my left Hand very fecurely into

are fufficient for this Purpofe ; and then I draw out
