fiderifig them with Attention, they will perhaps ra- 
ther be judged to be the feveral articulated Divifions 
that compofe the Body of fome kind of Nautilus , 
or of fome one or othei of the various Species of the 
Ammonites: Which Opinion is 1 think fupported, 
not only by the fpiral Figure, which they form when 
put together, but likewife by the Traces or Markings 
of fuch-like Articulations, found on fome particular 
Kinds of foffil Nautili and Ammonit£ } one whereof 
I alfo lay before you, as a Proof of this Conje&ure. 
You will obferve all the Parts of this uncommon 
Foflil are converted into a fort of fparry Subftancc, 
and that they are articulated with one another in an 
exatt and beautiful Order. I have fattened them to- 
gether in two Divifions, that they may be examined 
more eafily than they could be, if they were all fe- 
parate, and in Gonfufion : And indeed I am not 
quite fatisfied that thefe two Bundles belonged both 
to the fame individual Animal j if they did, fome 
Joints mutt be wanting that came between them, 
and united them together, as the two Ends do not 
at prefent match : And what makes me fufped they 
did not, is a different Articulation to be obferved 
on one Side of that Divifion made up of the largeft 
Joints: Befides, the whole Number appears rather 
too much, and the fmaller Joints feem to make up 
a Body whofe Figure is nearly perfed.
