T h e foffil-fliells of this difirtei,'and forts of done, fuch as
have fallen within my: obfervation, muft not be pafled over in
filence. And fitft I muft mention, as a great curiofity, a fpeoimen
that was plowed up in the chalky fields,*near the fide of the Down,
and given to me for the Angularity of : itT appearance, which, to an

I ever find in books' any engraving from a' perfeft one. In the

by the name Gorgonia. - The curious-foldings of the future the one

than by words, I have caufed it to be drawn and engraved.
