given us Tome very fine Thoughts, snd Ingenious Con* 
fe&ures concerning their Origin and Produ&ion $ and 
perhaps he may by this time have difcovered more clearly 
their Caufes. If this Paper of mine occafion his divulg* 
ing thofe Sentiments, how proud fhall I be of the Mid- 
wifery ! 
This is the only Difficulty all thofe Stories I havetoTd 
from others are incumbred with ^ but mine hath another 
no lefs hard to refolve. It’s obvious how thofe things 
were got out of the Women that dyed $ but my Patient, 
who furvived the Evacuation, puzleth me to find the 
Duttus per gucm for fuch a Lump to pafs from without 
the Womb into the Vulva . It was certainly lodged with- 
out the TJttrus’, But which way could fuch a Lump of 
greafy Hair, with a Bone, and a large Membrane adhe- 
ring, pafs into it ? I know none but th e Tuba Fallopian* 3 
but the Orifice of that into the Womb is fo fmall, that 
it fometitnes wont admit an Egg no bigger than a Corn of 
Pepper to pafs : Whence thole Conceptions which are 
made in that Trunk are occafioned. It will diftend very 
largely, fo as to hold a big Foetus 5 but where it is in- 
ferred to the Matrix, the Foramen is too narrow for 
Subftancesof fuch Magnitude to pafs, unlels fome very 
extraordinary Accident expanded it 5 and what that can 
be, I can’t apprehend.
