made the Incifion, on the left Side of the Urethra , 
with the (trait grooved Knife, which I ufed that Year 
in cutting Men, I withdrew the grooved Staff, and 
introduced the Groove of the Knife. 
Immediately after this Operation, I fhorten’d the 
Work, by reducing the three Inftruments to two. 
For that Purpofe I contrived to add to the common 
Gorget A A, Fig. i . and 2 . T ab. I. a grooved Staff BB. 
After placing and tying the Patient in the fame 
manner as for cutting Men, I at once introduce into 
the Urethra the End B of the Gorget, which con- 
ftitutes the grooved Staff, 1 turn the Groove towards 
the Patient’s left Buttock : On this Groove I pufh 
the Knife {Ur tthro-cijlit ome) Fig. 3. which is not 
grooved, nor fo broad as that which I made ufe of 
in 1735 on the Widow Neel. Having laid open 
the Neck of the Bladder, I lay afide the Knife, and 
thruft the Gorget farther into the Bladder ; for Ex- 
ample, as far as C. Then I pafs the Fore-finger on 
the Gorget into the Bladder, to dilate the Neck j 
which done, I introduce the Gorget as far forward 
as is ncceffary, and on it the Forceps. The reft of 
the Operation is performed as on Men. 
The firft of the Sex, whom I cut in this laft Me- 
thod, as appears by my Journal, is Magdalen le 
Marchand of the Tais de Caux , aged 22, cut in 
May 1738. I extracted a large Stone from her, and 
fhe was cured in ten Days. 
Since that time I have conftantly practifed this 
Method, which has fucceeded perfectly well. When 
the Stones were little, the Patients were cured in a 
few Days : But here is one, whofe fpeedy Cure has 
fomewhat furprifing in it ; inafmuch as I really be- 
lieve it the only one which has happen’d fo.
