This Motion vpon P re (fare , and the Reciprocal! thereof, which is 
Motion vpon Ten(ure * Wee vfe to call (by one common Name) Motion of 
Liberty \ which is, when any Body, being forced to a Preter-NfaturalL Ex¬ 
tent, or Demenfion,deliuereth and reftoreth itfelfeto the Naturall; As 
when a Blovene Bladder (PrefTed) rifeth againe • or when Leather or Cloth 
rent ured fpring backe. Thefe two Motions (of which there bee infinite in- 
ftances) we fhall handle in due place. 
This Motion vpon Preffure is excellently alfo demonstrated in Sounds h 
As when one Chimeth vpon a Bell, itfoundeth • butasfoone asheelay- 
ethhis hand vpon it, the Sound ceafeth : And fo, the Sound of a Virgin all 
string , as foone as the Quill ofa Iacke falleth vpon it, ftoppeth. For thefe 
Sounds are produced, by the fubtill Percuifion of the Minute parts, of 
the Bed , or String, vpon the Aire; All one, as the water is caufed to leape 
by the fubtile Percuftion of the Minuteparts of the Glaffe , vpon the Wa¬ 
ter , whereof wee fpake a little before in the ninth Experiment. For 
you mu l\ not take it to bee, thelocall Shaking of the Bell, ox String, that 
doth it. As wee fhall fully declare, when wee come hereafter to handle 
Sounds. 
T Akea GlaJJe with a Belly and a long Neb • fill the Belly (in part) 
with Water : Take alfo another Glaffe , whereinto put Claret Wine 
and Water mingled : Reuerfe the fir ft Glaffe, with the Belly vp wards. 
Stopping the Neb with your finger • Then dip the Mouth of it with¬ 
in the Second Glaffe , and remoue your Finger; Continue it in that 
pofture for a time ; And it will vnmingle the the wine from water: 
The Wine amending and fetling in the top of the upper Glaffe And 
the water defeending and fetling in the bottome of the lower Glaffe. 
The paffage is apparant to rhe Eye ; For you (Tall fee the wine^ as it 
were, in a fmall veine, rifing thorow the Water. For handfomndle 
fake (becaufe the Working requireth fomc fmall time) it were good 
you hang the vpper Glaffe vpon a Naile. But as foone as there is ga¬ 
thered fo much pure and vnmixed water in the bottome of the Lower 
Glaffe, as that the Mouth of the vpper Glaffe dippeth into it, the Motion 
ceafeth. 
Let the Vpper Glaffe bee wine , and the Lower water • there follow- 
eth no Motion at all. Let the Vpper Glaffe bee water pure ? the Low- 
I er Water coloured ; or contrariwife ; there followeth no Motion at all. 
| But it hath beene tried, that though the Mixture of Wine and water, 
in the Lower Glaffe^ bee three parts water , and but one wine • yet it 
doth not dead the Motion. This Separation of water and Wine appea* 
reth to bee made by Weight ; for it mu ft bee of Bodies of vnequall weight , 
or elfe it worketh not • And the Heauier Body muft cuer bee in the vpper 
Glaffe . Burthen note withall, that the waterbeiog made penfile, and 
there being a great Weight of water in the Belly of the Glaffe > fuftained
