Of OXFO%T)^SHi\E. 6i 
Mr. Hmry Sayero^ Magdalene College Oxon^ who commonly made 
ufe of a cinereous Earth, fomwhat tending to yellow, and finely 
chamletted^ that he found at the Quarries, in the gullies the 
Rocks in the Parifli of Heddington : with, which, as I am inform- 
ed by my worthy Friend Mr. Crcfs once his Apothecary^ and ftill 
living, he did as frequently, and as well procure Sweats, as with 
any of theForrcign earths whatever. 
29. To thefe may be added a whitiili fat earthy formerly of 
{omtw^tin external applications^ which they fetch'd, whil'ft the 
waters continued in requeft, from the oririce of the afore-men- 
tioned fpring at Goreing^ and phanfied it at leaft, to be a very 
good remedy for the of Corns, and fome other fuch mala- 
dies: but as foonastheir^/eri began to fail, the earth too (though 
ftillthere remain enough) began to decline in its reputation, and 
is now of very little, if of any efteem. 
30. There is another white e^r//> of fome ufe in this Coun- 
try, which fome will have alfo, as well as Lac Lun<z^ to deferve 
the name of mineral Agaric : it grows for the moft part within 
round hollow Flints, to be had almoft every where in the Chiltern 
Country, and good to ftop fluxes boiled in milk ; and I was told 
by an eminent Phyfitian, has been ufed in Confumptions with 
good fuccefs. The Hone in which it grows they call here a Chalk 
Egg^ and is the fame with the Gecdes of the ancient Naturalifis^ of 
whichj becaufe further in the 0^^//ero/f?om, I forbear to add 
more concerning it here.

found to be foveraign for Mans prefervation, but according to 
the Logicalrule of contraries^ fuch as often have been his deftru- 
dion too : Whereof there are fome in the Parilli of North Leigh, 
that fend forth fuch fudden and deadly fteams, that they kill be- 
fore the Patient can give the leaft notice, of which they have had 
two very deplorable examples. 
32. The firft whereof happened in Auguff^ about twenty years 
fince, when two men of the place imployed to dig a well, firft 
fickned, and wifely withdrew from the work : whereupon it was 
undertaken by two others of Woodftock^ men of greater refolu- 
tion andlefs wifdom ; who before they could do any thing con- 
fiderably in it, funk down and irrecoverably dyed in the well ; 
which quickly being perceived by a woman above, aM/7/^rhard
