Fig. i. Is a Belemnites , whofe Apex is perfect ; the 
conic Cavity, and the longitudinal Seam, evidently 
diflinguifhable ; which, as well as the Contexture 
of the Subftance whereof it is compofed, Chew it 
to be a true Belemnites ,* but on its Surface arc 
placed, in their natural Condition, by which I 
mean not at all feemingly petrify ’d, or othcrwife 
alter’d, two of thofe Vermicitli that are fo fre- 
quently found (licking to Oyftcrs, Scallops, and 
many other kinds of Shells, when taken out of 
the Sea. 
Fig. 2. A Frujlum of another Belemnites, the Apex 
whereof is broken, but the conic Cavity is dill 
remaining, and fhcwn at a. To this Belemnites 
adheres a Shell of the Oyfter-kind, which is faf- 
ten’d thereto fo (Irongly, that they are not to be 
feparated without breaking: Which Shell, as well 
as the before- mention'd Vermicitli , feems not al- 
tered in its Subftance, but appears like a recent 
one, of which many are to be met with in the 
Cabinets of the Curious. 
Fig. 3. Shews the other Side of the faid Shell, 
wherein the Car do or Hinge at b is plainly dis- 
cernible 5 at c appears the broken End of the Be - 
lemnites > where the radiated Contexture (well 
known to belong to their Bodies) is reprefented, 
as alfo the longitudinal Seam at d .
