to the Wood, confifting 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 ruffet or 
barque colour. Yet the black Rings, being held up againft 
the light, are tranfparent. So the cleared Glafs, in fome

lolves it with a vehement Effervefcence. 
A Stone expreffing part of a Tranverfe Settion of OLIVE-
