A fourth Difference mdykthh s Tha ^ whertoi a CoaJ , 
as it buries , [enis forth /lore of fmeke or exhalations 5 Luminous 
Wood does mt fo. 
J. A fifth 5 pmng from the former , is 5 i:hat ^ whereas a 
Coal in fhining wn[les it felf at a great rate , Shining Wood 
does not. 
Thefe two unlikencffes I mention together, not onely becauf^ 
of their affinity?^ but becaufe what concerns the C^?^/' in both; 
will need no proof ^ and as for what concerns Rotten Wood^ 
it na.ay be verified by an Obferv:tioa , thatlfind by my Notes^: 
I made in apiece of it Hermetically fealed up in a finaiicleir 
Glafs 5 where after it had continued laminous f. me dayes, I 
iookr on it in the day time to perceive , if any (lore of fpi- 
rics'or other fteams had 5 during all that while 5 exhaled from 
the Wood 5 but could not find any ontheinfideof the Glafs^, 
fave that in one place there appeared a kind of Dcw\^ bur con- 
fifting of fuch very fmall drops ( if at leaft their Size vvere not 
below that name ) that a multitude of them would g to the 
making up of otie ordinary drop. But in pieces of Shining 
Fi[h I found the cafe much otherwife 5 as was to be ex- 
pe&ed.. 
6, The laft Difference , / jhdl take notice of hetwixt the Bodies 
hitherto compared^ is, That a Quick Coal is aBuallf and vehe- 
mentlj hot ^ whereas I have not obfdrved Shining Wood ti^ be 
much as fenfthlyluke marm. 
What is f;iid of the Coals heat , being as manifeft as its 
light , I iliall need only to make out , what relates to the 
Shining Wood, To affiftme wherein , I meet among my Notes 
thatj'whofe tranfcript 1 fliallfubjoyn 5 when I have premisM, 
that (if my memory do not deceive me) the piece of Wood 
to be mentioned was one 5 that flione fo vividly , that waking 
in the Night fome hours before 1 tryed it , and perceiving, as 
it lay near me oa the Bed , how luminous it was, I was invi- 
ted to reach out to a place near the „Beds-.head , where there- 
flood feveral Books 5 and laying the Wood on that p \Ji'faich 
came to hand , I could difcera by the light of it , that the 
Book was an Hebrew Bible , and that of the Page, I lighted
