fuch-like Shells $ but as you fay, what's become of 

 all thefe Species, if they are petrified Shells ? I fay 

 they are all of the Nautilus Kind, not that any of them 

 fcarce referable the known Species of Nautili, (for 

 fuch as do have been called by Calceolarius and Mor- 

 cardo, Nautili, and not Cornua Hammonis) but 

 becaufe they confift of feveral Articulations, which 

 is a Stru&ure agrees with no other Shells but the Nau- 

 till. The Sutures upon them, which Boccone and o- 

 thers compare to Oak-Leaves, are nothing elfe but 

 the Commiflures of the Joints; and thefe Joints no- 

 thing elfe but the Spar, or other Stone, filling the 

 Cavities of the Cells in the Nautilus : And this 1 con- 

 clude from one or two Specimens I have found, which 

 have the Shell ftill remaining in the Interftices of the 

 Joints. That Figure of the Joints which I compared 

 to Fertebrte is acquired from the Shape of the Septum, 

 or Partition in the Shell. I think -Glaus Wormius was 

 the firft that compared any Cornu Ham. to a Nauti- 

 lus.
