blown afreih into it ^ I compreffed with my fingers the Vena, Cava. 
and the DuBus Thorackm together 5 but the wind , that was 
thruft into this Channel , fliewedus^ that it had another way to c- 
fcape. And indeed we faw as often as we did blow , that the 
Bmulgent Fein was on the left fide filled with wind , and that there- 
upon the body of ih^VenaCava alfo filled itfelf from the Emul- 
gent unto the llkques. This wind feem'd to us to come from the 
Left Kidney 5 and to infinuate it felf into the Emtilgent Fein y and 
thence into the C^x'^. The i^/g^^^iT/W/^^fj' had been removed , fo 
that we could fay nothing of its communication with the faid 
T>u6itis : That fliall be for another time. 
The Queftionwasmade, Whether the wind , thatfeemMto 
enter into the Emulgent ^ and the CavA , did there enter indeed j 
or, whether it did not Aide , betWixt the pofer coat of this Vein^ 
znd that common one , which comes to it from the Prntoneum'^ 
ThisQueftion did oblige us to flit the Cava at the place of the 
Emulgent 5 and th^n blowing into the Dh^^s 7'horacicm , we faw, 
that the wind, which had fwelkd the, Emulgent ^ did efcape at the 
opening, juftnowmadein theC/zw.; 
This Experiment made us judge , there was a communication of 
the BuBus Thoracictis with the Left Kidney , or at leaft with the 
^mulgent Fein , in the Body of this Woman. And to clear it the 
more, we madethe foUowiDg .Experiment. . 
2. We lifted with the hand the Lungs ^ thatfiUed theleft Ca- 
vity of the Thorax , and having cleanfed this Cavity with a 
3punge 3 M. Gay ant did blow into the iDUctus Thoracicm ^ whiFft 
i compreffed the Fein and the Ductus with my fingers upon the 
th^iiiiFertehra^ defcending from the Back ; And we faw the wind 
infinuate it felf under the ^/(f^r^, by a trace, which raifed it fud- 
denly as often as we did blow. This trace appeared from the ^th 
Ferttbra defcending unto the Diafhragme , and made us conclude, 
that there was under the Pleura a Channel of Commerce coming 
from the Ductus Thoracicus , and pafling to the jE^«?«/^^;;^ Vein by 
this Cavity of theThorax. We could not doubt, but that this 
Channel, which pafTed under the P/^-^r^., went as far as to the 
JKidnej ^ becaufe we faw , that the wind did get inonthe fi^eof 
the Kidney into the >Ew///^^;a^ Vein , and came out at the hole of
