28 C O N C HO LOGY. 



I have alfo collated fome copies of this 

 work, and found them all to dif<i^ree : 

 the moft perfeft copy in London is faid 

 to l^e in the library of the College of 

 Phyficians. 



Some foreign Natura lifts have bceti 

 pleafed to call Lifter's Hiftory a dry and 

 fterile work, alluding to its having no 

 defcriptions, but only fynonyms, though 

 in all other refpefts they extol it greatly. 

 But Mr. d'Argenville has carried his 

 cenfures on it beyond prudence or fenfe : 

 therefore it behoves me to take fome par- 

 ticular notice of that author. 



For example, he infinuates, that of the 

 lirft book of terreftrial Shells, three parts 

 of them are known to be marine ones. 

 Later difcoveries, without any accufarion 

 ot* Lifter, may have illuftrated this point 

 lince his time, were it really fo ; but, on 

 the contrary, it appears to me an erro- 

 neous affertioHe
