to the Wood, confiding of white and black Rings one 
within another. The other anfwering to the Barque, of two 
or three thin ones (like that of a Cherry-Tree) of a rufiet or 
barque colour. Yet the black Rings, being held up againft 
the light, are tranfparent. So the cleared Glafs, in fome 
podures, appears black. Spirit of Nitre droped on it, dif- 
folves it with a vehement Efervefcence. 
A Stone exprefling part of a Tranverfe Section of OLIVE- 
WOOD. On one fide, ’tis very well polifh’d. By means 
whereof, not only the Annual Rings (appearing in the 
Trunks of all Trees;) but alfo the hifertions or Farenchy- 
vious Rays which run betwixt the Pith and Barque, and 
even the greater Vcflelsthemfelves (either for Aer or Sap) 
arc all to a good naked eye, but efpecially with the help of 
a Glafs, very fairly vilible. ’Tis juft of the colour of the 
browner fort of Olive-Wood well varnifh’d. ’Tis as hard as

A large piece of PETRIFY’D WOOD (as itisfuppofed) 
above halt a yard long, and «of a yard about. 
Another Piece about the fame bignefs. 
A Globular Stone , which looks as if it had been a piece of 
ASH-WOOD turned in a Lathe into that figure. For it hath 
not only the colour, but the femblance of the Annual 
Rings, and of the Aer-Vefels , as in that Wood. 
Small pieces of (reputed) petrify’d Wood, commonly 
found between the Beds of blew Marble. Two inches long, 
and near as thick as ones little Finger. Almoft as black as 
Ebony. 
A Piece of INCOMBUSTIBLE Wood, as it were HALF 
PETRIFY’D. For being held in the fire, it becomes red 
like a Coal 5 but neither flames, nor fmoaks in the leaft. 
A very odd Piece of the BRANCH of a TREE as thick 
as a Cable-Rope, whereof the Barque is turned into perfect 
Iron, or at leaft a very rich Iron Ore ; and the Wood into 
Stone. The
