tients^ did as well burn in the open Air^ asinclpfe d^mp 
Vaults^ as that mention d by St. Jujlin in his book de Ci" 
vitate Det^ which hung in the Temple of Venus alwaies 
expoied to the open weather, yet was never either con- 
fumed or extingtiiili t. The Lamp a:fo found in the 
Tomb of Palim thc j^rcadian^ {lain hy Turn tM in the Tro- 
jan Wsirj was of this kind, which remain d burai ig af- 
ter it was taken forth, notwithftandmg either JVina or 
Water 3 with which fome did endeavor to quench it* 
Now admitting our Lamp at Fitcbford flioold thus burn, 
indifferently under both circumftances, what are we the 
worfe ? Smce 1 never heard that the Lamp mention d 
by St. Auftin, or of Pallas, were ever the leis efteemx-d 
or admired, becaufe they could not be extiiigiiiflic by 
the open^^v as moil of the reft have been faid to be. 
But if anybody be fo wife that He mufthave Q,nOyl in 
all parricuiars aniwerable to that other fort of t\\- An- 
cients, that burns beft where there is vpa?it oi A-r, and 
is deftroyed by its admiffion : let Him bet go with me 
into Flint-Jhire to the Coale-wor^ oiSi, J^ger Mopyfiot 
Mofiyn in that County , and He may have iatistactioo ; 
where the M/^^rj- when they have dugg fo deep^. that 
they begm to perceive a want ot ^ir, find a blewilb flaaie 
to begin to kindle of it lelf in the fiilures of the Coal 
(at which, by way of fport, they fometiiiies light their 
Candles) which blazes,' and moves op and down conti-^ 
nually, and fometimes Ihines too upon the forface of 
the water in the bottom of the Pits, fnewing all the co* 
lours of the I{ainboiv: which yet upon drawing up of 
the water that annoyes the works, and thereby ftirriog 
the Air , will leave burnings but as they fink lower, 
and are more remote from the day or fupertcrraneous Air, 
ftill increafes uoon them : whence it plainly appears that 
this is a fort of fire that fo little requires Atr for the 
maintenance of it that it burns beft w^ien there is leaft 
*^ir,and is extinguiftit when d ifturb'd by the motion of it ;
