I. 
A natural blind duCt y being a production of the true 
lamina of the peritonaeum by the rings. 
March f, 1750, in the dead body of Magdalen 
Vauchel, wife of Thomas Fermant, 46 years old, I 
found this dudt of the thicknefs of a goofe-quill, be- 
a production of the true lamina of the peritoneum 
ftretched out by the rings ; of which Swammerdam 
and Nuck difpute the difcovery, and Blancard denies 
the exiftence. What made me difcover this, was, 
that its extremity was widen’d into the fliape of a 
bubble as big as the top of a finger, and full of a 
watery humour. This woman had never had a her- 
nia, nor even the lead: tendency towards one. 
II. 
Strictures and carnofities in the urethra . 
Nothing is more common at this day than to hear 
people aflert, that ftriCtures and carnofities of the 
urethra are mere chimera’s ; that the bodies of per- 
fons, who were thought to have thefe ftriftures and 
carnofities, had been open’d, and that none of thefe 
had been found. I myfelf have made this obferva- 
tion, and I inferred thence, that there were ure- 
thra! s, in which a phlogofs , a fungous inflation gave 
occafion to the deception, being taken for itriCtures 
and carnofities : but if I had drawn this general in- 
ference, that of all the urethra's , wherein thefe ftric- 
tures and carnofities are thought to be found, not 
one has any thing in them, I fhould have been de- 
ceived, and would now make my recantation.
