Pliny that breaks and expels the {Icne^ if the Patient do but 
lick it. Of colour without, it is a whitidi yellow, and breaks 
into (hining white plates oblikely to the axi6 of the fior.e^ like the 
former, but whether made up of threds running differing 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 Tyfon A. M, zn 
ingenious and induftrious fearcher into the works of Nature and 
Arts,

at thtCafiade at Sommerton^ which though but a meer incruftation^ 
and formed not of it felf^ but ad formam olieriu6^ viz^, of the 
grafs about which it gathers, and therefore none of the Litho- 
fhjta ; yet it having fome jorm^ though but accidental^ I have 
thought rather fit to mifplace it here,than omit to Oiew the Read- 
er how prettily the grafi is fheathed with fione^ which is accu-^ 
ratly expreffed by Fig, 10.

to the flones refembling Animals^ either in the whole or parts ; 
amongft which, fome there are that feem to have been r^f/i/y pe- 
trified, which pofTibly enough coming to the places where they 
are now found iny?o;/e without the difficulties of z floods may be 
true enough too : though I know fome places in other Counties-^ 
where there are Cocbleomorf hit's or fnail-Jiones fo thick, that they 
feem unlikely to have ever been the f^oils of that Animal, In 
Oxford'JIfire indeed I have met with but two, one at Teyntcn^ and 
another in the rubble Quarries near Shotover-h\\\^ both which be- 
ing of the fame ftjape^ colour and bignefs, are reprefented toge- 
ther under Fig. 11. 
141. At the fame rubble Quarries we find alfo the Lapides ver- 
miculares^ oxworm-J^ones of two forts, whereof one is of a whi- 
tifli yellow colour, not hollow within, and as far as I could per- 
ceive of the fame texture with the rubble ftone it felf ; fome of 
them are of the bignefs of a fmall quill, and he in the rock in mezro 
nV/Vz/o irregularly contorted, much after the manner of the Ver- 
micchiara^ or Alcycnio Milefio of Ferrante Imperato as in Tab, 6. .

Jlone-y of a white colour, and regularly curled up like the
