^6 The S^tural Hijlory 
ftill in part put to that rervice,mixed with another they have from 
Northampton-Jkire, Itisalfo of excellent ufe to Statuaries^ for 
making Moddels^ Gargills^ or Antick§ ; and containing a hard, 
but very fmall grit ; mfolijhing Silver, it comes near to Tripela. 
44. And fo do's an anonymous very white earthy found in the 
feams of the Quarries zx.Teynton^ which at firft I concluded a crude 
Alahnfter^ becaufe I found near it a piece that was perfed" ' but 
reducing it into a very fine powder, and putting it over a quick 
fire, it would not boil like Alaha§ier duft, nor keep the colour, but 
turned reddifli. Many other tryals were made with it, in F la- 
flicks^ Polifling^ Paintings isrc. but my endeavors fucceeded in no- 
thing fo well, as in poli[ljing fmallerfilver Veffels, that could not 
endure hurniflnng well\ to which it gave a more glorious bright- 
nefs than Tripela would, though perhaps not fo lading ; and not 
far behinde that 6f burnilli'd Plate. 
45 . And yet neither this, nor the former will polifli Irofs^ nor 
any thing elfe that is not of its colour, which has lately engaged 
my thoughts lix-^Query^ whether in all other Metah the rule does 
hold : for I find, that fulphur gives a lufter to Gold ; and that 
nothing does brighten Copper fo well, as a fort of ftuff they cali 
rotten ftone^ alfo fomthing of its colour. , 
46. At Teynton alfo, within a fpit of the furface, they dig a 
fort of earth they there call Lam^ of a whitiih colour inclining to 
yellow ; which mixt with fand, and fome other earth, makes the 
beft earthen floors for ground-rooms and barns : it dilfolves as 
quick 2s Fullers-earthy and were it not for a fault which might 
pofTibly be help'd, it may ferve their turns perhaps as well as any 
they ufe. 
47. To thefe may be added another whitijh earthy which cor-^ 
ruptly I fuppofe from its colour is called Wbich-earth ; mixed with 
ftraw, they ufe it for fide-walls and ceilings, and with horfe- 
dung it makes mortar for laying of flones : it feem.s to be a natu- 
ral mixture of lime and fand^ found at Thame^ Waterperrj^ and 
Adwellj and flakes in water (like Gypfum) without any heat. 
48. At Milton near Adderbury^ Great Tew^ and Stunsfield^ I met 
alfo with another fort of fpungy chalk, which though it will not 
flake like the former ; yet at Milton and Jdderhury ufed for point- 
ing, fecms to bindethe ftones of their walls very well : and theirs 
Great Tevp being fomwhat finer, ferves as well to white their 
rooms
