thefe refemblances of Ihells, buc that Iron-ftone Cockles arc

Sparreor ChryftaiHoe-ftieHs all Sparre, &c. and thar they 
never were any part of an AnimaU My reafon is * That Quar- 
ries of difFerenc ttone ycild us quite difFerenc forts or fpeciei 
of (hells, not only one from another (as thofe Cockie-ftoces 
of the Iron-ftone Quarries of Adderton in Tor\'lhir£ differ from 
thofe found in the Lead^mines of the neighbouring moun- 
tains, and both thefe from that Cockle- Quarrie of Wamjord^ 
bridge in Nortbamptonjhire , and all three from thofe to be 
found in the Quarries about Gunthrop and Beavmr-Caflle^ 
but, I dare boldly fayj from any thing in nature befides^ that 
either the landj fair, or frelli water doth yeild us* 'Tis true^ 
that I have picked out of that one Qnarry of Wamford very 
refemblances of Murices^ Telince, Turbines^ Cochlece, &cc, and 
yet I am not convinced, when I particularly examined fome 
of our Englifh (hores for fliells, alfo the freih waters and the 
fieldsj that I did ever meet with (N^B.) any one of thofe 
Jpecies of fhells any where elfe, but in their refpeftive Quar- 
ries, whence I conclude them Lafides [ui generis^ and that they 
werenotcaftin any Animal mold, whole fpecies or race is yec 
to be found in being at this day.

and fuch general notions ; but when theyiliall pleafe to con- 
defcend to heedful and accurate difcripticns , they wiil^ I 
doubt notjbe of that opinion, which an attentive view of thefe 
things led me into fome years ago* Though \ make nodoubr^,

things of this nature 5 yet if you fliall command iliera 5 
I Will fend you up two or three fens of our Englifli Cockle-
