Mr. Henry Sayer of 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 of the 

 Rocks in the Parifri of Heddington : with which, as I am inform- 

 ed by my worthy Friend Mr. Crofs once his Apothecary, and frill 

 living, he did as frequently, and as well procure Sweats, as with 

 any of the Forreign earths whatever. 



29. To thefe may be added a whitifh fat earth, formerly of 

 fomeufe in external applications, which they fetch'd, whil'ft the 

 waters continued in requeft, from the orifice of the afore-men- 

 tioned faring at Goreing, and phanfied it at leall, to be a very 

 good remedy for the ach of Corns, and fo me other fuch mala* 

 dies : but as foon as the waters began to fail, the earth too (though 

 ftill there remain enough) began to decline in its reputation, and 

 is now of very little, if of any efteem. 



30. There is another white earth of fome ufe in this Coun- 

 try, which fome will have alfo, as well as Lac Lung, to deferve 

 the name of a mineral Agaric : it grows for the moft part within 

 round hollow Flints, to be had almoft every where in the Chilterrt 

 Country, and good to flop fluxes boiled in milk ; and I was told 

 by an eminent Phyfitian, has been ufed in Confumptions with 

 good fuccefs. The ftone in which it grows they call here a Chalk 

 Egg, and is the fame with the Gecdesof the ancient Naturalifts, of 

 which, becaufe further in the Chapter of Clones, I forbear to add 

 more concerning it here. 



31 . Hither alfo muft be referred not only the earths that are 

 found to be foveraign for Mans prefervation, but according to 

 the Logicalrule of contraries, fuch as often have been his deftru- 

 ction too : Whereof there are fome in the Parifli 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 flrft whereof happened in August, 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 Wood/lock, men f greater rcfolu- 

 tion and Iefs wifdom ; who before they could do any thing con- 

 fiderably in it, funk down and irrecoverably dyed in the well i 

 which quickly being perceived by a woman above, a Miller hard
