any Recrements ^(As Iron-Jione affords ftoreof a dark Glafs 
or Slagg) and if it do, what chofe Recrements are > How they 
are feparated from the Metal ? and to what Ufes they are em- 
ployed? 
9©* Whether, afrerthe Metal hasbeenonce melted, the 
remaining part of the Ore being expofed to the Air, will in 
trad: of time be impregnated , or ripen d, fo as to afford more 
Metal } ( For, this is affirmed to me of the Cornifij Tin-Ore 5 
and what remained after the fufion of Iron ore in the Forreft of 
Dean^ is fo rich in Metal , that a Tenant of mine in Ireland , 
though he had on the land he held from mCjanlron mine,found 
it lels profit to work it,than to fend crofs the Sea to the Forreft 
ofDesn for this already iis'd OrCjWhich having lain for fome 
ages^finceit was thrown afide in great heaps expos'd to the Air, 
he affirmed to yield as well great ftore of Iron, as very good : 
though I fomewhat doubt, whether thisbe tobe afcri-

with no other kind of mineral in fome diftin^ftpiart of it? (As in 
l^entnezr Tunbridge ^ one part of the Country which is Hilly^ 
abounds all along with Iron-mines the other , which is alio 
Hilly^and divided from it but by a fmall Valley, abounds ex- 
ceedingly ( as the Diggers and Inhabitants told me upon the 
place ) in ^arrys^ which the Me taline-Country wants, but 
'is quicedeftituteof Iron-jione, And fo Mendip , in one part 
of the Hill 5 I (aw ftore of Lead-mines ^ containing feverall 
Kinds of Ore of that metal ^ another part of the Hill I found to 
be fall of Co/e-pits, whichhad (omQ Marsha/itej:^ but no metal s 
and in another place, Iron^ere^ and mixt with Ores , which yet 
they did not think fit to work )
