A Difficulty, which naturally offers itfelf in this 
l 5 lace, is attempted to be removed What Proof 
'have we, that this, which is called Wood, is not mere 
foil'll Wood, the Product of Creating Power, exerted 
in the Place where it is now found ? — - It is anfwered, 
That as there are undoubted Proofs, that many Sub- 
ftances now occur, where they were not originally 
framed, we are under no greater Difficulty in account- 
ing for the Change of Place in one than the other. 
It is known, that the Exuvia of Fillies are fome- 
times found on the Tops of the higheft Mountains. 
The Bones of large Animals are met with at prodi- 
gious Depths, where Nature never formed, nor Art 
conveyed them. Whole Woods are found under- 
ground. The Caufe that effeded thefe, was capable 
of the other. 
Yet, allowing thefe Allegations to be juft, by what 
Caufes is this Change produced ? It is urged, That 
Time is one of the Caufes and that the reft is com- 
pleted by the Acid of the Earth, a vitriolic mineral 
Acid. It is proved, from the Fads above-mentioned. 
That fuch an Acid is prefect where-ever Amber occurs 
in its proper Matrix : That it is fometimes found in 
the Amber itfelf, in its genuine Appearance; That 
the Acid of the Salt of Amber appears, from Experi- 
ments, to be vitriolic; That common Turpentine 
(a known vegetable Rcftn) affords, by proper Ma- 
nagement with a vitriolic Acid, a confiderable Por- 
tion of the fame chemical Principles that Amber 
does; That thofe Pieces of Amber, which have been 
found foft and inlperfed, are nearly related to a 
vegetable Refin : In ffiorr, it is endeavoured to 
be proved, Thar we have the Ingredients of 
Amber
