107. They that think the Cornua Ammon'n, or Ophiomorphites. 

 to have been formerly nothing but Porcellane-fiells, feem alfo to 

 be prerTed with the like difficulties : for either there are feverai 

 forts of them not known to (I am furenotdefcribed by) Author^ 



or elfe our flones muft have their formation from a different mold 

 than their fiells. For fir ft, theftells feem to be extravagantly 

 broad at the mouth, as defcribed by Rondektiws zndfonflon, and 

 not to have more than two other fmall turns at moft ; whereas the 

 turns of the Ophiomorphit's are proportionable to one another, 

 and in number many times four or five, and fomtimes fix, if we 

 may believe Aldrovandus x : Of which difference Chioccm y feems 

 to have been fo well aware in his defcription of the latter part of 

 the Mufdtum Calceolarium, that he makes the Cornu Ammonis and 

 Nautilus lapidem to be quite different things, and defcribes the 

 latter very broad at the greater end, and with but one turn, fom-* 

 what like indeed to the Porcellane-fiell. 



108. Befide, fo far are fome of our English Opbiomorphif s 

 from ever having been formed by the fiell of the Nautilus, that 

 at Huntley-Nab in the North-riding of Tork-fiire, they are found 

 always included in other great round Jiones, not unlike, fays Mr. 

 Cambden z , to Cannon bullets. And at Whitby, fays Mr. Hay % in 

 (tones of a lenticular figure, which if formerly they had been the 

 pells of Nautili, how they fliould become thus included in flones 

 aifoof -a determinate figure, is a difficulty more infuperable than 

 any of the former. Add hereunto that Mr, Cambden b , and fince 

 him Dr. Cbildrey c plainly avouch, that the Ophiomorphif 's ofCain- 

 fiam, have fome of them heads, and that in this they differ from 



thofe of Torkrfiire : Vidimus aiim lapidem bine delatum ferpentis in 

 ffiram revohti effigie, cujus caput in circumferentia prominuit, extrema 

 cauda centrum occupante, are the very words of Mr. Cambden. 

 Which if I find true when I come into Svmerfet-ftire, will give me, 

 and I doubt not, others fatisfa&ion beyond all exception; for 

 that the fiells of the Nautili have any fuch matter, no body yet 

 has, nor will dare to pretend.

 whereof there are fome it feems near two d foot in diameter, far
