n6 The 5\(jttt4ral Hijlory 



Pliny w , that breaks and expels the ilone^ if the Patient do but 

 lick it. Of colour. without, it is a whitifh yellow, and breaks 

 into Chining white plates oblikely to the axis of the (lone, like the 

 former, but whether made up of threds running diifering ways, 

 I could not afford to try, having but one of the kind ; which 

 was found and given me, befide feveral other matters of the 

 fame nature, by my very good Friend Edward Tjfon A. M. an 

 ingenious and induftrious fearcher into the works of Nature and 

 Arts. 



139. Hither alfomuft be referr'd the frefh water Adarce made 

 at the Cafcadt at Sommerton, which though but a meer incrujlation, 

 and formed not of it felf, but ad formam alterius, viz. of the 

 grafs about which it gachers, and therefore none of the Litbo- 

 pbyta ; yet it having fome form, though but accidental, I have 

 thought rather fit to mifplace ithere,than omit to (hew the Read- 

 er how prettily the graft is fhesthed with flone, which is accu- 

 rately expreffed by Fig. 10, 



140. Thus having done with the Lapides <putd^$, T proceed 

 to the ffones refembling Animals, either in the whole or parts; 

 amongft which, fome there are that feem to have been reptils pe- 

 trified, which poffibly en6ugh coming to the places where they 

 are now found in flone without the difficulties of a flood, may be 

 true enough too : though I know fome places in other Counties, 

 where there are Cocbleomorpbit's ox [nail jl ones fo thick, that they 

 feem unlikely to have ever been the [foils of that Animal. Jn 

 Oxfird-ftire indeed I have met with but two, one at Teyntcn, and 

 another in the rubble Quarries near Sbotover-h\\\, both which be- 

 ing of the fame ffiape, colour and bignefs, are reprefented toge- 

 ther under Fig 1 1 . 



141. At the fame rubble Quarries we find alfo the Lapides ver-> 

 miculares, or worm-Jlones of two forts, whereof one is of a whi- 

 tifh yellow colour, not hollow within, and as far as I could per- 

 ceive of the fame texture with the rubble /lone it felf; fome of 

 them are of the bignefs of a fmall quill, and he in the rock in mezjo 

 rilievo irregularly contorted, much after the manner of the Ver* 

 micchiara, or Alcycnio Milefw oi~F err ante lmperato *, as in Tab, 6. 

 Fig. 13. whereas the other fort lies in the very body of the 



fione-> of a white colour , and regularly curled up like the
