you will never find any of the lymphatick Veflels broken. 
We (hall then take the true Caufe from the Mechanick 
Strudiure of the parts,and the difpofition of the Blood, 
which are fir ft the Relaxation of the Fibres and Pores of 
the VeiTels^or the f^^f/cw/^^jWhich are between the Arteries 
and theVeinSjOr lecondly,a connipreflion of the Veflels ; for 
theLynnphaticks take their Origine fiom the Membranes, 
which covers theMuicIes^z/cfra and G/Wj^ therefore, 
when the Veficula are too much ftraitned with Serofity, 
theirFibresJoofe their natural force,and become uncapable 
to exp^l the too great quantity of Water ; but the f^efi- 
cul(Z are enlarged from day today, until their Fibres fuf- 
fer fo great an Exrenfion even as to break, from hence is 
the fource of thofe Waters ; it happens alfo fometimes, 
that the pores of the faid Feficul<e are fo widened.that the 
Lymph runs inro the Cavity of the Belly, or the Inter- 
fticesof theMufcules. 
The Caufe from the Difpofition of the Blood, is either 
when it is too thin or too vifcid ; too thin, that it pafles 
eafily through the Pores of the Veficules ; too vifcidjthat 
it cannot pais through the Capillary Veffels,and by con- 
fequence Compreffes the adjacent parts, fo caules Ob' 
Ilruflions. I (hall infift no further as to the Caufe,onIy 
take Notice, whether in reafon this Woman could have 
lived any time longer, confidering all the Complex, of 
Difeafes ; or if the Operation ot the Paracentefis was 
the Caufe of her being fooner carried off: From what is 
faid above, it is impofiible (he could Recover ; only this 
is to be remarked, that where the Dropfie is of a long 
continuance, and the Perfons much Debilitated and of 
Age, in that Cafe the Operation is not to be performed,- 
for generally the Vifcera are Corrupted. 
When ye perform the Operation, Extrad the Water 
-by degrees, and not all at once, elfe you endanger the 
Perfbn, for fcarce One efcapes of a Hundred that is done 
other wife. W. Ah
