The Natural Hiflory 



and it may very reafbnably be conclu- 

 ded, that all thefe Jlrangt Shells, which 

 we cannot fb match, are of thefe Pe- 

 lagU : that the feveral kinds of them 

 are at this day living in the huge bo- 

 Ibm of the Ocean ; and that there is 

 not any one intire fpecies of Shell-fifli, 

 formerly in being, now perifh'd and 

 loft. 



That it is alfo very true that there 

 are fome Shells, fuch as thofe of the 

 larger Buccim, and Concha VemriSy of 

 Lobfters, Crabs, and others of the 

 cruftaceous kind, that are very rarely 

 found at Land ; lb rarely ^ that Ibme 

 of thefe Gentlemen have afTerted that 

 they are never found ; but that I lliall 

 fhew to be a miftake, all the Shells in 

 their whole Lift having been found in 

 the Earth in one place or other. But 

 that thefe are very feldom found any 

 where, I moft readily grant 5 and this 

 is lb far from being an Argument 

 againft what I am going to advance, 

 that 'tis as full and fubftantial a Proof 

 of the truth of it as I could poffibly 

 wilh. For the Shells in this Lift are 

 all lighter than Stone, Marble, and 

 the other ordinary Terreftrial xVfatten 

 Now both thefe and all other forts of 



Shells
