ally, fometimes higher in one part than in another, 
fhooting it feif very pleafingly into - Branches clivers 
ways, and fo v/ould continue till it had arriv’d to its 
greatefb height ; but that would be according to the di- 
lia nee tile Planes were plac’d afunder : for ifj inffead of 
one, two pieces of Paper were laid on each corner of the 
Planes, the Water then would not alcend fo high be- 
tween them, as when they were feparated only by a (in- 
gle one. And then, if the Planes were any ways declin’d, ’ 
the Water would ftill fpread it fclf farther and far,ther, 
.agreeable to the degree of Declination ; and this on fe.- 
veral tryals fucceeded much the fame. 
EXPERIMENT II. 
Having feen the. fuccefs of the former Experiment in 
the open Air, I was willing to try what appearance' it 
would afford inVacuo ; accordingly I fixt the two Planes 
fo to a Brafs Wire, ( which pall: thro’ the Cover of a Re- 
ceiver^ that I could make them d'efeend at pleafure. In 
this manner, with a- Difli of ting’d Liquor, I convey’d 
them within the Receiver ^ which having plac’t on my 
Pump, I proceeded to exhauff its contain’d Air, which 
the Gage, in a little time, difeover’d to be pretty nicely 
done. Then I plung’d the Planes (feparated by Pieces 
of thin Paper as before) into the Water, where, as in 
the open Air, it arofe between them ; only with this dif- 
ference, fhat there appear’d more Intervals, or Spaces, be- 
tween the Branches of the afeending Liquid, than in the 
former Experiment : but when I came to let in the Airj 
thqfe Intervals vanifh’d, and an intire Body of the Li^ 
quid fucceeded ; yet the exad form of the upper parrs 
of it remain’d imalter’d.
