5521Century I.
It is reported of very good credit, that in the Eaſt-Indies if you ſet a
1178. Tub of Water open in a Room where Cloves are kept, it will be drawn dry
in Twenty four hours, though it ſtand at ſome diſtant from the Cloves.
In the Countrey, they uſe many times in deceit, when their Wooll is new
ſhorn, to ſet ſome Pails of Water by in the ſame Room, to encreaſe
the weight of the Wooll:
But it may be, that the Heat of the Wool re-
maining from the Body of the Sheep, or the heat gathered by the lying
cloſe of the Wool, helpeth to draw the watry vapor;
but that is nothing to
the Verſion.
It is reported alſo credibly, that Wool new ſhorn, being laid caſually
2279. upon a Veſſel of Verjuice, after ſome time hath drunk up a great part of the
Verjuice, though the Veſſel were whole without any flaw, and had not the
Bung-hole open.
In this inſtance there is (upon the by) to be noted, the
Percolation or Suing of the Verjuice thorow the Wood;
for Verjuice of it ſelf
would never have paſſed through the Wood:
So, as it ſeemeth, it muſt be
firſt in a kinde of vapor before it paſs.
It is eſpecially to be noted, that the cauſe that doth facilitate the Ver-
3380. ſion of Air into Water, when the Air is not in groſs, but ſubtilly mingled
with tangible Bodies, is, (at hath been partly touched before) for that tan-
gible Bodies have an antipathy with Air;
and if they finde any Liquid Body
that is more denſe nearthem, they will draw it;
and after they have drawn
it, they will condente it more, and in effect incorporateit:
For we ſee that
a Spunge, or Wooll, or Sugar, or a Woollen-cloth, being put but in part, in
Water or Wine, will draw the Liquor higher, and beyond the place, where
the Water or Wine cometh.
We ſee alſo, that Wood, Lute-ſtrings, and the like,
do ſwell in moiſt ſeaſons;
as appeareth by the breaking of the ſtrings, the
hard turning of the Pegs, and the hard drawing forth of Boxes, and opening
of Wainſcot doors, which is a kinde of infuſion;
and is much like to an in-
fuſion in Water, which will make Wood to ſwell;
as we ſee in the filling of
the Chops of Bowls by laying them in Water.
But for that part of theſe
Experiments, which concerneth Attraction we will reſerve into the proper Title
of Attraction.
There is alſo a Verſion of Airinto Water, ſeeing in the ſweating of Mar-
4481. bles, and other Stones;
and of Wainſcot before, and in moiſt weather. This
muſt be, either by ſome moiſture the Body yieldeth, or elſe by the moiſt Air
thickned againſt the hard Body.
But it is plain, that it is the latter; for that
we ſee Wood painted with Oyl-colour, will ſoonergather drops in a moiſt
night, than Wood alone;
which is cauſed by the ſmoothneſs and cloſeneſs,
which letteth in no part of the vapor, and ſo turneth it back and thickneth
it into Dew.
We ſee alſo, that breathing upon a Glaſs, or ſmooth Body,
giveth a Dew;
and in Froſty mornings (ſuch as we call Rime Froſts) you
ſhall finde drops of Dew upon the inſide of Glaſs-windows:
And the Froſt
it ſelf upon the ground, is but a Verſion or Condenſation of the moiſt va-
pors of the night, into a watry ſubſtance:
Dews likewiſe, and Rain, are but
the returns of moiſt vapors condenſed;
the Dew, by the cold onely of
the Suns departure, which is the gentler cold;
Rains, by the cold of that
which they call the Middle Region of the Air, which is the more violent
Cold.
It is very probable (as hath been touched) that that which will turn
5582. Water into Ice, will likewiſe turn Air ſome degree nearer unto Water.
Therefore try the Experiment of the Artificial turning Water into Ice
(where of we ſhall ſpeak in another place) with Air in place of Water,
