Hog's Lungs, and poured in warm Water, 
which neither flowed into the pulmonary 
Arteries, nor among the Bronchi^^ an Argu- 
ment that this Force did not burfl: the Veins, 
which fome Anatomifts (ay, have no Valves

Windpipe of thofe Lungs, and poured in 
Water, it paflfed thro* the Bronchia and ran 
out of the Orifice of the pulmonary Artery, 
but not above one fifth fo faft, as when its 
Courfe was the reverfe, 'viz, from the pul-

when Air was blown into the Cavity of the 
Lungs, thro* the Windpipe, none palTed thence,
