my prefent enquiry into what i^uthors havefaid con- 
cerning the Operation of Opiunij and how it procures 
eafe in this and fuch like Cafes ; wherefore I lhall ooiy 
relate what occurred when with an Ingenious Perfon and 
my felf, we examined a Solution of Opium with my 
Microfcope ; the Particles of the diflolved Opium ap- 
peared like fringed Globules. Theft Particles we were 
inclined to think (if (b conveyed to the Mafs of Blood} 
might fo intangle in its Serum and thicken if, as to oc- 
cafion a retardation of the Globules of the Blood, and 
hinder their progreffive Motion, at the extremities of 
the Blood Veflels : Hence the Blood not paffing with its 
wonted vellocity, does not fo liiddenly extend thofe en- 
larged Veflels, , which have a confiderable (hare in the 
intumefcence of the part but by making the Globules 
of the Blood pafi more calmly, might prevent their 
fudden efforts , or intrufions into thofe diftended Vef- 
fels. The intumiiied Kidney not only eompreft the 
left fpermatick Vein, whereby the Refluent Blood of the 
Vterus, f^agina and parts adjacent, was infome meaflire 
retarded, but fome of the Nerves of th^ Fagina, and 
theft of the Pudendum i were alfo eompreft thereby ; 
hence Pain arifing from Inflamation, thro' a retardation 
of the Blood, at the extremities of the vaft number of 
Blood Veflels, about the MeatusVrtnartus, at its egrefs 
in the Vagina ; whence Exulceratioo and Mortification 
followed. The Magnitude of this Kidney prevented the 
bending forwards of the Trunk of the Body, whence it 
was flie was obliged to keep it ereft. The lower part 
of the left Kidney, had fo preft on the left Mufculus 
PfoaSf as fcarce a tliird part of its proper bulk remain-
