As thcfe Specimens are undeniable Proofs of ma- 
rine Bodies adhering to Belemnit£, feveral of the Cu- 
rious who have feen them-, are of Opinion, that they 
tend likewife to prove the Belemnita to be marine 
Productions. It may • probably be objected, that 
thefe Shells might have been brought and depofited 
near the Belemnit£ whereto they are affixed, by 
whatever mighty Change it came to pafs that Pro- 
ductions of the Sea are difcovcr’d in mod Countries 
at great Depths in the Earth, and in the Bowels of 
Mountains at great Diftances from the Sea (even 
fuppofing the Belemnit £ to be Lapides fni generis , 
and produced in the Earth) and that thefe Shells 
might be cemented to them afterwards by lome mi- 
neral, flony, or other Matter. But the following 
Obfervations will render this improbable 5 for, 
1. The Ver 7 niculi of Fig. 1. are not any Species of 
the Tubnli marini, found fometimes recent, and 
fometimes foflil, detach’d intirely from every other 
Body; but are of that fort, which is perhaps never 
feen feparate, or in any other Manner, when recent, 
than attach’d and faften’d to other Shells or Stones; 
and they are placed on this Belemnites exaCtly in the 
fame Manner as they are commonly found on other 
marine Bodies ; <viz. lying on their broadeft Side, 
with their Ridge upwards, and glued as it were thereto 
by a fhelly Subftance. 
2. In Fig. 3. at <?, is plainly to be diftinguifhed, 
that the Shell has been falhion’d thus by the convex 
Surface of the Belemnites , in the fame manner as 
thefe Shells commonly receive a Form from what- 
ever Subftance they adhere to ; which plainly implies, 
that this Shell was faften’d to the Belemnites when 
itfelf
