Trochart of the Paracent hefts, which he propofed 
to thruft in between the Tuberoli'cy of the Os If 
chium and the Anus , directly into the Body of the 
Bladder 5 and on which he was afterwards to intro- 
duce a fharp Ihftrument of his Invention, to make 
a proper Wound for extrading the Stone. He made 
Trial of thefe Inftruments on a dead Body ; and, in 
fine, he cut a certain Number of Patients for feveral 
Years fuccdTivdy in that manner. People are di- 
vided on the Succefs which attended thefe Trials : 
Much has been written againfl it 5 and I have heard 
a great deal faid in its Favour by good Judges. One 
Advantage, which flatter’d me in this Method, was 
that of its not being liable to occafion Incontinencies 
of Urine, nor even Fijiulas , as I was allured ; Incon- 
veniences from which the lateral Operation is not 
exempt in the Cafe of large Stones, becaufethis Ope- 
ration attacks the Bladder in its Neck. But one De- 
fed of Mr. Foubert’s Method, which his very Partizans 
cannot help taking for an effential Inconvenience, 
is, that the Operator thrufls the Trochart in toward 
the Bladder without any thing to guide him, and, 
as it were, by Guefs. ’Tis needlefs to inlarge on 
the fatal Confequences of this Defed they appear 
at firft Sight j and are fufficient to make one refufe 
giving even the Name of a Method to fo uncertain 
a Way of Cutting. Neverthelefs, if this Way of 
Cutting had other wife great Advantages, and that one 
could clear it of that Blemifh which overcafts it, by 
giving it this Guide which it wanted, and render- 
ing its Procefs fteady and certain, it muft be allowed, 
that it would prove an excellent Method, a lateral 
Operation of the fourth Sort, worthy of being put
