aflertthem to be contained. * 
As for the Earthy Contents ^ he finds them alfo to be 
two only i vi!^. Brown Osre (which is a term of Painters 
to diftingulfb it from Tellow Ocre ) this being a fort of 
IronGre, and Lime-ftone. Now to demonftrate this as 
to matter of fa<ft : that thefe Earths were fuch and no o- 
then he hath at large defcribed all the feveral forts of Iron 
Ore;, which he hath met within England » and the true 
way to know them by the Loadftone- And in this Hifto* 
ry he hath fhewn xhit xht Pyrites \sh\xtoi\tn\ England^ 
and that meer Iron Ore > under what name or figure or 
difguife foever it comes before us. In like manner he 
hath given the true Notion and Charafterof Lime-ftone^ 
which alfo he might have at large defcribed according ta 
the feveral fpecies he hath by him , which poflibly he 
may do when more at leafare. 
Now how thefe Earthy Contents and Salts come to be 
mix't in the Water^ and what relation they have one to the 
other , you fliall thus underftand. - - . ' 
All Iron Ore, but moreefpecially tfie Pyrites ('w\iic\i 
is every where andin ali ^XdiCt^ oi England plentifully to 
be found:, at leaft fparjim and in lumps or Glebcy and fome 
places in Beds) Alfo all Limeftone ("which is the great bo- 
die of moflofthe Mountains and Rocks in England)\l 
moiftned and wet , as they muft be where they are cleft , 
and give way to the foak and fubterraneous current of 
Springs ^ both thefe he fays, moiftned, naturally Ihoot 
there Salts. 
Now the Salt of the PynW or Iron Ore xsGrem Vitriok 
and the Salt of Lime-flone is the Nitre by him defcribed. 
That thefe Salts are lliot not inft^ntly, and as in their 
Cryftallization, or by Coagulation,or Corrofion > but by 
a leafurely and natural growth or Germination analogous 
to that of Plants or Animals, 
That therefore the life of thefe growing Salts is in like 
manner halituous and naturally Warsue, and may if copi-
