tifully provided with Blood veffels, for it received from the 
^<?r/4 two Arteries, which before their infertion, were each 
fubdivided into three branches J and it fent out two veins, 
which being joyned afterward into one, entered the Vcn/i 
f4W. Befides at the Seam at the lower part of the left 
Kidney, it had a Vein and Artery, which afterwards infertcd 
themfelves into the like branches of the jiorta and Cava^ fo 
that Nature though erring from her wonted Rule in forming 
this parr, yet was provident in furnilliing it withVefTels. 
But to the whole Compages of the Kidney's, there be- 
longed only two Ureters^buc the great dilatation of the Pelvis 
in each was remarkable ; for that of the left Kidney when 
blown up, was larger then it is reprefcmted in the figure.anJ had 
a triple origination; The right had but a fingle one and was 
lefs. 
Whether this Conformation and ftruftureof the Kidney's 
and its Veffels were of much inconvenience to the Patient, 
I (hall not define; but am apt to think^that it might occafion as 
well the great dilatation of the Tif^ii C/it/4jasalfoof the Pelvis: 
for r he middle part conjoyning both the Kidneys lying over 
the Fern CavA, by its weight prefling thereon,would hinder the 
free return of the Blood, which yet would make room for its 
felf, by enlarging its own Channel, which was fo capacious as 
^o contain three or four of my fingers. So likewife the Ure» 
. ers running over that part that conjoyns the Kidaeys like 
firings over the Bridge of a Viol, in fome Pofition of the Body 
they might have their paflage fo ftreightned, that the Urin be- 
.ng impeded and regurgitating , might fwell and ftrctch the 
Membrane of the Pelvis to this greatnefs.
