fince, in the midle of the Market-place, 
there was cut out a Stone full of ftreak-

the Cockles,now found in the faid ftones, 
were already produced at that time when 
the VolAterrAn walls were rais’d. And 
leaft it fhould be faid, that the Shells a- 
lone, being turn’d into ftone, or included 
in ftone, had fuffec'd no daniage by the 
vyaftfal time 5 'tis to be noted, that the 
whole Hillock, on vvhich the moft anci¬ 
ent Town of the Etrurians is built, rifeth 
out of the fediments of the Sea, laid on 
one another,and parallel to the Horbon 5 
where many Beds not ftony do abound 
with true Cockles that have fuller’d no

ly fay, that thofe Cockles, which at this 
day we have drawn from thence, and 
that are unchanged, have been produced 
Three Thoufand Years ago, and more. 
From the building of the City of Rome 
until thefe times we reckon about 242,0. 
Years: And who wifi not grant that ma¬
