ward by degrees, are all atlaft turn'd into an abfolute white 
Spar,with fome BhphaneityA difcover'd the fa«)e Earth in fonie 
places there growing fphencaijwhich whiift it is Earth,it is ftill 
fiicking to its bed j but afterwards, as it comes to be crufted 
over,and at laft to be turn'd into Spar like the other ^ it grows 
clear off from its root , as fruit falls from the tree when ripe, I 
have by me of thefe Spherical ftones , from the bignefs of an or- 
dinary Bullet to that of a great Pins- head, fomc turning to Spar 
fooner than others; I found fomc quite grown off, fome half 
grown, fome white Spar outwardly, and raw Earth in the mid- 
dle^ fothat the procefs was as plain to me as I could wifli.I faw 
th€ fame Earth in fome places there growing in an exaft oval 
form, and turning into Spar not oval, but rais'd on both fides 
with an edge round it like an Apricock-ftone: And as thefe 
fpherical and oval ftones are moft exaft in their figure; fo, not- 
withftanding the ReSor fails in this Vault to give a true fexan- 
gular figure to thafe which I (aid Choot up pyramidally ; yet 
there is a certain place on thefe hills, where the Spar^ grow all 
fexangular, both points of them terminating into a pyramidal 
figure, fexangular likewile,as the veins of Cryftal,found in Italy^ 
produced by a coagulation of Dew ; thefe with us probably 
having the fame rife, lying a!fo on the furfacc of the earth.Here 
I may acquaint you, that I find on thefe Hills growing fex- 
angular ; the ruft,which often lies over veins of Lead-oar, in ma* 
ny places (hoots up pyramidally , and is bounded round with 
^ fix anglesjand fometimes with five: Lead-oar it felf often fhoots 
^p pyramidally with rough irregular lines round it,and in fome 
places I find it bounded round very regularly with four angles; 
in otiier places it grows branched like a Plant^s I have feen in a 
Mine where the Stone-plants grow. 
To come x\o^ to t\\t Vegetation o[ thefe plants, I find, they 
begin their growth from the fineft parts of clay ,being commonly 
white,foft and finooth at firft^and by degrees come to have ridg- 
es, knots and futures, as they grow towards a ftony,and fo to a 
Jparry nature* The pith continues ftill foft and white, as the 
whole is at firft , and its continually refreftt by the Mineral 
fteamSj and moifture, which have free accefs to ic through the 
five hollow flirts or feet in the figured roots,or through the mafs 
of clay which commonly lies under 'the plain roots; this free
