Experiment XX. 
I. TTTHEN Tubes were fixed at the fame 
W time to the left carotid Artery, and 
alfo to the left crural Artery, and Water pour- 
ed into the Tube at the carotid Artery, Co as 
to be four Feet feven Inches high in that Tube, 
then it would rife four Feet four Inches in the 
other Tube : And when the Water fubfided fix 
Inches in the carotid Tube, it would propor- 
tionably fink in the other Tube and rife again 
when chat was filled up. When the Column 
of Water in the carotid Tube was 9 -hi Feet 
high, then it rofe in the other Tube eight 
Feet eleven Inches. The Inequality of the 
feveral Heights of the Columns of Water, 
was as I guefs owing to the Smallnefs of the 
brafs Pipe which was fixed to the carotid Ar- 
tery, on which Account it was not fufficient 
to fupply in full Plenty what ran off* to wafie 
in the other Branches, and at the fame time 
keep up the Water near to an equal Height 
in the ocher Tube, which it would doubtlefs 
have done, if by a larger Pipe the Tube had 
been fixed to the defeending Aorta.
