open into the cava, and fo'to the heart. The ferous part is ftrained through the 
papillary caruncles, which have holes into the branches of the ureters, and after grow 
together into one cavity or expanfion of the wrefer, into which the ferum is emptied ; 
through the ureters it pafes into the bladder, where it becomes urine, * 
The deputy kidneys, or black choler cafes, are fo feated, that they reft upon the 
upper part of the kidneys, on the outfide, where they look towards the vena 
being covered with fat membranes, "In figure and fabftance they for the moft part 
reflemble the kidneys, fave that their fleth is a little loofer: fo that they feem like 
little kidneys refting upon the Great ones, They have an apparent internal cavity, 
furnifhed with a dreggy and black humour; and are ftrongly connected, where 
they reft, to the external membrane of the reins, and to the /eptum sranfoerfum, to 
which they commonly ftick in diffe@tion. | 
The ureters, are white vefiels, like veins, but thicker, whiter, and more nervous ; 
confifting of a fingle membranous fubftance, inclofed in a duplication of the perito- 
ucum. ‘They are as long as between. the kidneys and bladder, and commonly as 
thick or wide as goofe-quills : but, in diffection of perfons troubled with the ftone, 
they have been fo wide as to admit of two fingers. Their original is in the kidneys, 
within whofe cavities they are divided Into nine or ten little pipes or channels, 
which are fitted to the little Aefhy teats or caruncule papillares, that they may diftil 
the ferum into the pelvis, or bafon, or large cavities of the ureters within the kid- 
neys. The ureters, defcending within the duplicature of the peritoneum, upon the 
mufcles of the loins, to the bladder, are inferted obliquely into its neck ; then, af- 
jcending upwards between its membranes, they perforate the innermoft coat 
and through the fame hole they both enter the bladder: in the implantation of the a 
ureters, two little membranes or valves are placed, like the valves in bellows, nae 
ting up the paffages of the ureters, fo that the urine cannot go back. They receive 
_ and marrow of the loins, Their ule is to convey the urine from the kid 
‘the bladder. eee Sigler e
