Before we come to the Iron-ftoncs , our Author eoniiQ^^^ 
thofe great Quarries of Marble, Alabafter, and other ufef^^H 
ftones difpersed up and down the Country ; all which he 
fuppofes to be made by a Petrification upon the meeting 
thefolutions of Aced and Alkalifate falts , which compound 
transparent, opake, and femiopake ftones, as they are 
mixed with fulphures or Earths of diflPerent fineffes. He 
conftders Pebles and Fireftones by themCelves , as wherein 
the Sulphur is predominant ; and therefore are they eafely 
Caicinable. When he comes to the Iron-workes he explaines 
the way how their Fornaces are built, how they melt their 
Iron-ftone, how the goodnefs is .dilcernable, and the like. 
As for the Copper-mines tried by Sr. Rich : Fleetwood , they 
would turn to no Account, 
Other ftones have been fbmctimes found in Stafford/hire^ 
which have had a determinate Form, as the JJteria of a Pen- 
tagonall fiirface, with Rayes ilTuing from the Center, and to 
each angular point. Thefe are either inch as relemble Ani- 
mals or fome of their Parts; fb one was found like a Pullets 
heart, others like moft Teftaceous Fifties, which have been 
long theught to be petriiyed fliells, tho Ibme Naturahfts are 
perfwaded to the contrary ; or elfe fiich as are like Vege- 
tables, whereof in mineral ftones and Oares there is great 
Variety. Gold Oare hath refembled Branches of Trees, and 
Wormius had a piece of filver Oare exaftly like a Vine; which 
Figures are ordinary in Bohemia d.s Ba/bims informs us, and 
when he afterwards fpeakes of the Entrochi and Trochita he 
explaines very curioufly feveral Figures not taken notice of 
hy My. Beaumont. Cap. 5. 
Next he comes to Plants, tho' there he owns httle can be 
added to what Mr. Ray bad found in his accurate Cata- 
logue of Englsflj Plants, yet he found fome few omitted by 
him, as a fort of Cup-Mojfe with Scarlat Heads, and fome 
Fungi tho the Fungus Fhalloides is defcribed, and a Cutt an- 
nexed in the ad. Edit, of Mr. Rayes Catalogue ] together 
with fome few Trees, which Mr. Ray took for ftrang-
