by along ufe of the Vicrofcope r and his deducYidns from them, He 
affirraes, that he hath always observed, the Kidneys to be alfoa 0#~ 
crete of fmail Glanduls , by injecting through the Emulgenc Artery a 
black liquor, mixt with fpirit of wine, and by cutting the KUmfs 
longways, a i nd then finding, betwixt the Urinous Veffels and their 
interfaces, very many of fucb glanduls which like lirle apples are ap- 
pendant to the Sanguineous, veffels, turgid with that black liquor. Ke 
adds, th.it, after many trials, he at laft found alfo a connexion betwixt 
thofe Glwdnls and the Veffels of Urine. / s to the Pelvis , he makes 
that nothing but an Expanfion of the Vreter, as confiding of the lame 
membrane and nervous fibres with the Ureter. Difcourfing of the Vfe 
of the KidMefshe finds it difficult to explain, by what art and mechanise, 
Nature fo copioufly excretes by the Reins ( whofe glandular flrudure 
feems to be uniforme ) a liquor, which is con pounded of Aqueous, 
Saline, Sulphury and other particles, and fomecimes therdicks of im- 
pofthums, and other filth of the Body: Where he takes great pains, in 
fome meafure to clear that matter; adding thereunto the manner of the 
Stones generation m the Kidneys. 
In the Exercitation about the Spleen, having premifed , as before 
in the other parts, what has been hitherto pubhfh't about it, he fub- 
joyns what himfelf hath further obferved therein: viz. That the 
whole body of the Spleen, however it may feem to be a A; b (lance 
made up of concreted blood, yet is indeed a Compexof Membranes, 
fafhionM and diftinguiftrt into little Folds and Cellf^ clearly to befeea 
by fyringiog into it (lore of Air by the Ramus fplemcus , whereby the 
whole Spleen will become fo turgid , as to fwell into an exceflivc big- 
nefs; which if upon the exficcation of the thus fwelled part, it be pre- 
fently cut , its whole mafle will be found made up of Membranes, of the 
fhape of the Cells in Bee-hives; as he affirms to have clearly feen in 
the Spleen of a Sheep and Hogg, and in that of a man. But then he 
adds , that through this whole membranous Body of the Spleen are 
copioufly difperfed Ciuflers of Glanduls, or, if you will, Bladders, 
very plainly refembling Clutters of Grapes- appendant on the fibres, 
arid the extremities of the arteries and nerves of that body. Coming 
to difcourfe of the Vfe of the Spleen, after he hath examined the va- 
rious opinion of Anatomifts concerning it, anddeclar'd his duTatisfadi- 
on therein , together with the reafons thereof, he does with great 
modefty as well as ingenuity offer his thoughts sbout it, viz. That, 
confidering the whole ftructure of the Spleen 3 it feems to be defign- 
ed for a new feparation and mixture of tbe Iuices conveyed it to it's Glan- 
duls by the Arteries and Nerves , and theR collected in the Cells ; 
whereby and by it's ft ay there, the Blood receives fuch a further change, 
and is fo much more exalted, that being convey 'd by the Splenetic^ 
Branch into the neighbouring Liver and there refermented, it re- 
quires a difpofition, for an eafy feparation of the Gall there (which is 
fuppofed to be the chief work of the Liver. )
