lefs noife than fait it felf; and in neater, after a quick and fub- 

 tile folution, leaves behind it a kind of brackifh taft, which I 

 thought might proceed from a fort of Vitriol, and perhaps true 

 enough* though the water would not tinge with powder of galls J 

 it takes greafe out of cloaths extreamly well, and would it but 

 whiten, as Fullers earth doth, I fliould not doubt to pronounce 

 it the fame with the viridis Saponaria, found near Beichling in 

 Thuringia, and mentioned by Rentmannws in his colle&ion of 

 Foffils w . This we have in great plenty in Shot-over Foreft, whefe 

 'tis always met with before they come to the Ochre, from which 

 it is feparated but by a thin Iron cruft, and may peradventure be 

 as ftrickt a concomitant of yellow Ochre, as Chryfocolla (another 

 green Earth) is faid to be of Gold. At pfefent 'tis accounted 

 of fmall or no value* but in recompenceof the fignal favors of* 

 its prefent Proprietor, the Right Worfhipful Sir Timothy lyrril, 

 who in perfon was pleafed to fhew me the pits, I am ready to 

 difcover a ufe it may have, that may poffibly equal that of his 

 Ochre. Which brings me next to treat of iuch Earths as are 

 found in Oxford-Jhire, and are ufefulin Trade9. * 



13. And amongft thefe the Ochre of Shotover, no doubt, may 

 challenge a principal place, it being accounted the beft in its kind . 

 in the world, of a yellow colour and very Weighty, much ufed 

 by Painte r s fimply of it felf, and as often mix'd with the reft of 

 their colours. This by Flirty x , and the Lathes, was anciently 

 called Sil, which we have now changed for the modern word 

 Ochra, taken up as fome think from the colour of the Earth, and 

 the Greek word *%&<, Pallidum ; or as others, and they perhaps 

 more rightly, from the River Ochra that runs through Brunfwick^ 

 whofe Banks do yield great quantities of it y ; and from whence! 

 in all likelyhood we received the name, upon the arrival of the 

 Angles and Saxons in Britan. 



14. They digit now atShotOver on the eaft fide of the Hill, 

 on the right hand of the way leading from Oxford to Whately, 

 though queftionlefs it may be had in many other parts of it ; The 

 vein dips from Eaft to Weil, and lies from feven to thirty feet 

 in depth, and between two and feven inches thick ; enwrapped 

 it is within ten folds of Earth, all which mull be paft through 

 before they come at it ; for the Earth is here, as at moft other
