5. A fifth , flowing from the former , '.is ? T&4*, whereas a 
Coal /» Shining mftes it [elf at a great rate , Shining Wood 
does not . 
Thefe two unlikenefies I mention together, not onely becaofe 
of their affinity •, but becaufe what concerns the Coal in both, 
will need no proof 5 and as for what concerns Rotten Wood , 
it may be verified by an Obfervrtion , that 1 find by my r Notes 
I made in a piece of it Hermetically fealed up in a final! clear 
Glafs 5 where after it had continued luminous feme dayes , I

What is faid of the Coals vheat , being as manifeft as its ^

Shining Wood. To affiftme wherein, Imeet among my Notes 
that, whofe tranfeript 1 fiiall fubjoyn , when I ''have premis’d,, 
that (if my memory do not deceive me) the piece of Wood 
robe mentioned wasone , that ffionefo vividly', that waking 
in the Night forne hours before I tryed it , and perceiving, as 
it lay near me on the Bed , how luminous it was, I was invi- 
ted to reach out to a place near t{ic- Beds-head , where there 
flood feveral Books and laying the Wood on that > .Which 
came to hand , I could difeern by the light of it , that the 
Book was an Hebrew Bible , and that of the Page, Plighted,
