Qenturj . I. 
Infiance ^ wherein two things are moft remarkable * The one • that one 
I FUm within another quencheth not, but is a fixed Body, andcontinu- 
| eth as -Aire, or Water doe. And therefore Blame would ftillafcend up- 
f wards in one gveatnelfe, if it were not quenched on the Sides • And the 
greater the Flame is at the Bottome, the higher is the Rife. The other, 
that Flame doth not mingle with Flame, as Aire doth With Aire, or Wa- 
ter with' Water, but onely remaineth contiguous; As it commeth to palfe 
betwixt Confining Bodies. Itappeareth alfo, that the forme of aPira- 
mis in Flame, which we ufually fee, is meerely by Accident, and that the 
Aire about, by quenching the Sides of the Flame, cruflheth it, and ex¬ 
tents teth it into that Forme * For of it felfe it would bee Round : And 
therefore Smoake is in the Figure of a Piramis Reucrfcd $ Forth* Aire 
quencheth the Flame, and receiueth the Swaake, Note alfo, that the 
Flame of the Candle, within the Flame of the Spirit of Witte, is troubled • 
And doth not onely open andmoue vpwards, but mouethwauing, and 
to and fro r As if Flame of his owne Nature (if it were not quenched) 
would rowie and tiirne, as well as move upwards. By all which it 
fhould feeme that the Cadeftiall Bodies, (mold of them) are true Fires, 
ox Flames, as the held $ More fine (perhaps) and Rarified, than 
our Flame is. For they are all Globular, and determinate * Theyhaue 
Rotation • And theyhaue the Colour and Splendour of Flame : So that 
Flame aboue is Durable, and Confident, andinhisNaturallplace • But 
with vs, it is a Stranger, and Momentary, and Impure j Like Vulcan that 
halted with his Fall, 
T Ake an Arrow , and hold it in Flame , for the fpace of ten pulles ; And 
when it commeth forth, you fhall finde thole Parts of the Arrow, 
which were on tbeOutfides of the Flame , more burned, blacked, and 
turned aknoftinr.oa Coale 5 whereas that in the Middell: of the Flame, 
willbee, as if the Fire had fcarce touched it. This is an Infiance of great 
conlequence forthedifeouerv of the Nature of Flame ; And fheweth 
manifeftlv, that Flame burneth more violently towards the Sides, than 
intheMiddeft : And^ which is more, that Heat or Fire is not violent or 
furious, but where it is checked and pent. And therefore the Peripate- 
tickes (howfoever their opinion of an Element of Fire abotie the Aire is 
iuftly exploded ;) in that Point they acqu it themfelves well: Forbeing 
oppoled, that if there were a Spheare of Firet hat incompafled the Earth 
fo neere hand, it were impolfible but all things fhould be burnt up * They 
anfwer, that the pure BlementalL Fire , in his owne place, and not irritate, 
, is but of a Moderate Heat . 
I T is affirmed conftantly by many, as an ufiiall Experiment ; That a 
LumpeotVre in the Bottomeoi a Mine, will be tumbled, and ft irred, 
by two Mens ftrength ; which if you bring it to the Top of the Earth , will 
aske Six Mens ftrength at the leaftto llirre it. It is a Noble Infiance, 
and is fit to be tried to the full: For it is very , probable, that the Motion
