; blown afrefli Into it , I comprefted with my fingers the Vena Cava 
and the Dufftk lhoracicus together 5 but the wind 9 that was 
thruft into this Channel , (hewed us,, that it had another way to e- 
fcape. And indeed we faw as often as we did blow , that the 
Emulgent Fein was on the left fide filled with wind , and that there- 
upon, the body of the Vena&ava alfo filled itfelf from the Emul- 
gent unto the Mfaques. This wind feem’d to us to come from the 
Left Kidney , and to infinuate it felf into .the Emulgent Vein > - and- 
thence into the Cava. T he Right Kidney had been removed fo 
that we could fay nothing of its communication with the faid 
Duel us : That (hall be for another time. 
The Queftionwas made, Whether the wind, that Teem'd to 
enter- into the E? nulgent , and the Cava , did there enter indeed 5 
or, whether it did not Aide, betwixt the proper'cozt of this Vein, 
and that common one , which comes to it from the Peritoneum ? 
This Queftion did oblige us to (lit the Cava at the place of the 
Emulgent $ and then blowing into the Lucius Lhoracicus , we faw, 
that the wind , which had fwelled the Emulgent , did efcape at the 
-opening, juft now made in the Cava. 
This Experiment madeus judge, there was a communication of 
'the Euffus Lhoracicus with the Left Kidney , or at leaft with the 
■ 'Emulgent Vein , in. the Body of this Woman. Andtoolear it the 
more,, we made the following Experiment. 
2. We lifted with the hand the Lungs , that filled the left Ca- 
-vity of the Thorax , and having cleanfed this Cavity with a 
Spunge , M. Gayant did blow into the Ductus Lhoracicus , whifft 
•I comprefted the Vein andtheD/^j- with my fingers upon the 
third Vertebra , defcending from the Back : And we faw the wind 
infinuate it felf under the Pleura , by a trace , which raifed it fud- 
• deniy as often as we did blow.. This trace appeared from the 4th 
Vertebra defcending unto th eDiaphragme , and made us conclude.* 
■that there was under the Pleura a Channel of Commerce coming 
from the Ductus Lhoracicus 3 andpafling to the Emulgent Vein by 
this Cavity of the Thorax. We could not doubt, but that this 
Channel , which pafted under the Pleura , went as far as tOthe 
Kidney , becaufe we faw , that the wind did get in on the fide of 
tiie«Kidney into the Emulgent Vein, and came out at the hole of
