SIR, 
I Was called, fome time ago, to open a Maiden Lady 52 
years of age, who complain'd, about fix weeks before, 
of a Circonfcript hard Swelling on the Hjipograjlka regio^ 
on the Right fide^ from that time her Belly grew by de- 
grees to an exorbitant bignefs, the great weight whereof 
was the moftconfiderable Symptom, and at laft foffocated 
theLady» The Body was mightily emaciated, and the 
Legs fwelled few days before her death. 
I expefted Water, but there was only a ^^ifcuous darkifb 
Humour, to the quantity of 18 Gallons \ after the evacin 
ation of that matter, f was no lefs furprized to perceive a 
Itrgeheap of Vefcicles arifing from a thick Membrane co- 
vering the Guts, it being the PmV^;/e;/«z feparated frbm 
Ilie Mufcles: I took it out, to examine, the better thofc 
Vefcicular Bodies difpofed on the outward furface of that 
Mcmbmne, as alfo them that wefe on its infide, towards 
the Guts. The Vefcicles were of different magnitude; $ 
feme of the largeft had been broken and fu ik/ other*4 were 
broken and almoft empty, and the others very n^itch c!i
