Full text: Bacon, Francis: Sylva sylvarum

THe Sea is clearer when the North-wind bloweth, then when the South-
wind. The cauſe is, for that Salt-water hath a little Oylineſs in the Surface
there of, as appeareth in very hot days: And again, for that the Southern-
wind relaxeth the Water ſomewhat; as no Water boyling, is ſo clear as cold
Water.

FIre burneth Wood, making it firſt Luminous, then black and brittle, and
laſtly, broken and incinerate; ſcalding Water doth none of theſe. The
cauſe is, for that by Fire the Spirit of the Body is firſt refined, and then emit-
ted; where of the refining or attenuation cauſeth the light, and the emiſſion; firſt the fragility, and after the diſſolution into Aſhes, neither doth any other
Body enter. But in Water, the Spirit of the Body is not refined ſo much; and beſides, part of the Water entreth, which doth increaſe the Spirit, and
in a degree extinguiſh it; therefore we ſee that hot Water will quench Fire. And again, we ſee that in Bodies wherein the Water doth not much enter,
but onely the heat paſſeth, hot Water worketh the effects of Fire: As in
Eggs boiled and roaſted, (into which the Water entreth not at all) there is
ſcarce difference to be diſcerned; but in Fruit and Fleſh, where into the Wa-
ter entreth in ſome part, there is much more difference.

THe bottom of a Veſſel of boyling Water (as hath been obſerved) is not
very much heated, ſo as men may put their hand under the Veſſel, and
remove it. The cauſe is, for that the moiſture of Water, as it quencheth
Coals where it entreth, ſo it doth allay heat where it toucheth. And there-
fore note well, that moiſture, although it doth not paſs through Bodies with-
out Communication of ſome ſubftance (as heat and cold do) yet it worketh
manifeſt effects; not by entrance of the Body, but by qualifying of the heat
and cold, as we ſee in this inſtance. And we ſee likewiſe, that the water of
things diſtilled in water, (which they call the Bath) differeth not much from
the water of things diſtilled by Fire. We ſee alſo, that Pewter-Diſhes with
Water in them will not melt eaſily, but without it they will. Nay, we ſee
more, that Butter or Oyl, which in them ſelves are inflamable, yet by the vir-
tue of their moiſture will do the like.

IT hath been noted by the Ancients, that it is dangerous to pick ones Ear
whileſt he Yawneth. The cauſe is, for that in Yawning, the inner Parch-
ment of the Ear [?] is extended by the drawing in of the Spirit and Breath; for
in Yawning and Sighing both, the Spirit is firſt ſtrongly drawn in, and then
ſtrongly expelled.

IT hath been obſerved by the Ancients, that Sneezing doth ceaſe the Hic-
cough. The cauſe is, for that the Motion of the Hiccough is a lifting up of
the Stomach; which Sneezing doth ſome what depreſs, and divert the moti-
on another way. For firſt, we ſee that the Hiccough cometh of fulneſs of
Meat, (eſpecially in Children) which cauſeth an extenſion of the Stomach: We ſee alſo, it is cauſed by acide Meats or Drinks, which is by the pricking
of the Stomach. And this motion is ceaſed, either by Diverſion, or by Deten-
tion of the Spirits: Diverſion, as in Sneezing; Detention, as we ſee holding
of the Breath doth help ſome what to ceaſe the Hiccough, and putting a Man
into an earneſt ſtudy doth the like, as is commonly uſed: And Vinegar put to
the Noſtrils or Gargarized doth it alſo; ſor that it is Aſtringent, and inhibiteth
the motion of the Spirit.
