not Open it againc. 
VT J Ater, being contiguous with Aire, Cooleth it, but Moiftenoth it 
V\^ not, except it Fapour. The Cauje is, for that Heat, and Cold haue a 
Virtuall Tranjition , without Communication ofi Sub fiance • but Moifture 
not: And to all pA^defMion there is required an Imbibition: But where 
the Bodies zxeoi ilich feuerall Leuity, and Grauity, as they Mingle not, 
there can follow no Imbibition. And therefore, Oyle likewife lyeth at the 
Top of the water, without Commixture: And a Drop of Water, running 
fwiftly oner a Sr aw, or Smooth Body, wetteth not. 
S Tar-Light Nights , yea, and bright Moone-pine Nights , are Colder than 
Cloudy Nights, The Cauje is, the Drinefje and FinencjJ'co? the Aire, 
which thereby becommeth more Piercing, and Sharpe: And therefore 
Great Continents are colder than ljlands: And as for the Moone, though 
it felfeinclineththe Aire to Moifittre, yet when it fhineth bright- itar- 
gueth the Aire is dry. Alfo Clo/e Aire , is warmer than Open Aire ; which 
(it may be) is, for that the true Cauje of Cold, is an Expiration from the 
Globe of the Earth, which in open Places is ftronger- Andagaine, Aire 
j itfelfe, if it bee not altered by that Expiration, is not without fome Se- 
j cret Degree of Heat: As it is not likewife without fome Secret Degree of 
Light: For otherwife Cats, and Owles, could not fee in the Night h But 
that Aire hath a little Light, Proportionable to the Vijuall Spirits of 
thofe Creatures. 
T He Eyes doe moue one and the feme way • For when one Eye mo- 
ueth to the Nofl hr ill,the. other moueth from the Nojlhrill. The Cauje 
is Motion of Confent, which in the Spirits, and Parts Spiritual, is Strong. 
But yet Vfe will induce the Contrary: For feme can Squint, when they 
will V And the Common Tradition is, that if Children be fet vpon a Table, 
with a Candle behind them, both Eyes will moue Outwards • As affe¬ 
cting to fee the light, and fo induce Squinting. 
- Wee fee more exquifitely with one Eye Shut , than with Both Open. 
The Cauje is, for that the Spirits Vijuall vnite themfelues more, andfo 
become Stronger. For yon may fee by looking in a GlaJJe, that when you 
flint one Eye, the Pupill of the other Eye, that is Open, Dilateth. 
The Eyes, if the Sight meet not in one Aygle, see Things Double. The 
Cauje is, for that Seeing Two Things, and Seeingone Thing twice, wor- 
keththe feme Ejfetf: Arid therefore a little Pellet , held betweene two 
Fingers laid a-crofle, feemeth Double. 
Pore-blinde Men, fee bed in the Dimmer Lights •, And likewife haue 
their Sight Stronger neere hand, than thofe that are not Pore-blinde, And 
canRcade and Write fmaller Letters . The Cauje is, for that the Spirits 
Vijuall, in thofe that are Pore-blinde, are Thinner and Rarer, than mo¬ 
thers; And therefore the Greater Lkht difperfeth them. For the fame
