to the Wood, confiding of white and black Rings one 
within another. The other anfwenng to the Barque, of two 
or three thin ones ( like that of a Cherry-Tree) of a ruffet or 
barque colour. Yet the black Rings, being held up againft 
the light, are tranfparent. So the clearer!: Glafs, in fome 
poftures, appears black. Spirit of Nitre droped on it, dif- 
folves it with a vehement Ejjervefcence. 
A Stone exprciling part of a Tranverfe SeWwn 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 5 ) but alfo the Insertions or Pdrenchy- 
mous Rays which run betwixt the Pith and Barque 3 and

a Glafs, very fairly vifible. "Tis jurt of the colour of the

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-Veffels, as in that Wood.

A Piece of INCOMBUSTIBLE Wood, as it were HALF 
PETRIFY'D. For being held in the fire, it becomes red 
like a Coal $ but neither flames, nor' fmoaks in the leaft. 
A very odd Piece of the BRANCH of a TREE as thick

Stone. The
