M. de la ^ryme has alfb feen in this quarry fbme fhell-fifh 
half open, and filled with the matter of the bed, wherein they he 
and petrified therewith ^ others being in heaps together, he found 
Ibme of them broken, others bruifed, and th* edges of one fiih 
thruft into the fides of another 5 Ibme with one Ihell thrult half 
way over the other, ^c» and thus petrified in the bed together 5 
others have been fodole together in the fame bed, that the mat- 
ter of the bed could not infinuate itfelf into them 5 fome of thele 
that are thus found are wholly empty, others are filled with cry- 
flalline fluors, tho* fuch are not very common^ Ibme M.Je la 
Tryme faw half full of the faid bluifh clay of the bed, and half 
full of the faid cryftallizations, which proceeded from fubterra- 
neous heat and cfttuvia 5 amongft the filh in this quarry, he had 
feen leveral large horle-mufcles, fuch as breed in freih-water 
rivers and ponds, which are exactly like the Concha Longa Ron- 
del, but are thicker and fuller than they commonly are 5 this 
iargenefs proceeds from the fertility and fatnels of the bed, where 
they breed 5 and in an old pond near S rough t on- balh he found 
fome of the largeft of this fort of ihell-fiih he ever faw ; as if 
this foil was the propereft for breeding them of any elle 3 juft as 
the Cornu Ammonis^ Nautili and others breed beft upon allum 
foil 5 which is the reafon they are found fo much at Whitby y 
Rochely Lunenburg^ Rome^ and other places, where there are 
allum -mines 5 and to find any of thefe Ibrts of filh (which fome 
learned men have thought to be totally loft) they might probably 
find them upon allum-loils in the lea. 
Others have an ouzey foil, a fort of mixture of ieveral foils, 
as part of the country about Frodinghamy 'Brambery AJhbee^ 
'Botfixorthy Sic. feems to be 5 in the fields and ftones of which 
towns is one particular fort of fifh, which he does not know 
what Ge^us or fpecies to compare it to, bending Ibmewhat like a 
ram's horn, and exactly crealed on the outfide like one, with an 
Operculum or lid thereon, which the fifh opened and ihut, as it 
had occafion^ the bed wherein this fifh bred, in the antedeluvian 
fea (as he fuppoles) is not above a foot thick, in which, but efpe- 
cially in the luperficies, are millions of the faid fifh flicking half 
in and half out of the ftone^ whofe fhell being moll durable, 
that part which flicks out, is not confumed, as that at Sroughton^ 
but remains whole and entire 3 and M. de la ^ryme had leen 
whole heaps of them, that by Ibme great weight falling upon 
them at the deluge have been fhattered to pieces, and lb petrified 
in the bed where they lay : In the parifh of Srougbton afbre-
