Herevpon some opinions were mentiond about the originall of Gold.
mr. Henshaw said it was an inquiry worth consideration, whence the seuerall shapes
of Gold proceeded vizt. that found in the mines and that washt out of the sand of
Riuers. for that they seemd to be very differing, that found in mines being always found
in thin plankes imbodyed in a hard stone, but that in Riuers being of quite an
other shape vizt like sand, hence he conceiud it worth inquiry whether the same
might not be generated out of the riuer it self.

mr. Hooke was of opinion that the originall place of gold lay exceeding Deep in
the earth. as being a body heauier then any other we yet know, and conse
quently ought to Lye Lower then any in order. that had It not been for some
former earthquakes and Eruptions the source would haue still remained in those
inaccessible recluses and soe haue neuer been known as in Probability many
other sorts of stones, mineralls, oars & mettalls which may lye below the
seat of subterraneous fires may remaine concealed and vnknown to this
Day. that by meanes of subterraneous fires ^ /earthquakes/ or other vapours that cause those
effects he conceiues those more profound and inner parts of the Earth may haue been
thrown vp together wth. the other effect of the same Cause the very mountain
that that part of it which is thrown vp into the tops or body of the mountaine
may by the violence of the heat & Discharge of the Vapours melted ^ /in the raising/ & Disper
/sed/ and broken into a multitude of very small globules or such like figure & soe
be blended & mixt wth the earth sand &c of the new eruption. that being
thus mixed wth the earth /of/ the mountaine the Raine falling the on the
vpper parts thereof & Descending washeth down into the riuers those smaller
particles of the Gold and soe Leaues them in the bottom of their channells
mr. Wheeler produced a Cod of Scammony /mentioned the Last Day/ bearing a fine kind of
Down like silk growing on the end of the seeds like those of Dan
delion by which they fly in the air like those and by the wind
are Dispersed at a great distance. This was Deliuered to mr
