35. Nor mufl: I forget the Iron-JIoneSit Shot-over^ tliouglioC" 
cafionally mention'd, and its ufes delated, in the ininiediati/ 
pteceding Chapter of Earths : fo called, not from any fiich metal 
that it holds, but meerly I fuppofefrom the colour 'tis off. This 
I tryed with the Load-pone and Aqua fortis^ thinking thereby, if 
it held any /ro/?, it mull needs have confeft it to one of thofe 
two. But I fince have found the Eocferiments but ill applyed, for 
neither will Cavala (which is the beft Iron-ore) anfwer either of 
them : So that I do not now condemn it to be no Iron-ore^ upon 
thofe grounds as at firft, but from other confiderable differences 
it has from the known Iron-ores of Glocefier-fiire and Sujfex. 
^6. There is alfo near Thanie on Cutthhrookrfide^ another Irort^ 
coloiif dftone^ but more fpungy than the former, and including 
within it a blackifli kind of Cinder ; the moft like, of any thing 
I yet have feen, to Magnefta (in the Glafs houfes^ called ilfi^;/- 
ganefi) only it wants of its clofenefs of texture and weight : 
what it (liould be, or for what ufe likely, to me I confefs is 
wholly m^Vnown^ unlefs 1 may call it the Siderites of Fliny^, I 
therefore defift to fay more about it, but commend it to the dif- 
coveryof future ages. 
37. At Eyfield-merrymouth^ in the Field above the Cave lately 
made by Mr. Bray^ in the bank near the Brook, I found a ^one of 
a light yellow colour, made np of glittenng Lame llae^ or Plates, 
which according to the defcription of Georgiws Agricola% feems 
not unlike the Samian-ftone^ found alfo about Hafda in the Biftiop- 
t'lckof HiideJ/jeme, and good only for poliftiing y?/z/er andgoW^ 
Such laminated Stones by Nicolas Steno ^ zre thought to be no- 
thing but incrufiations^ made in the confines of ay?wi^/and folid, an 
opinion that feems to come near to the truths However it be, ir 
is fomthing formed^ and may well ferve to ufher in the next Cha- 
pter, which I have wholly refer ved for /or;7fe^/y?o«e5.
