FTALY. LETTER V. 59 



don, which clearly appears in the fcaglia of Vi- 

 cenzaj but I fee the poffibility, the probability, 

 and the evidences, of either of thefe opinions: 

 and, I prefume, Nature comes at the fame end 

 by different ways, Perhaps this opinion, if ever 

 ventured to the public, will be more than fuffi- 

 cient to bring a charge of mineralogical herefy 

 upon me , efpecially if I mould happen to be 

 judged by people who never have feen or exa- 

 mined any volcano, but are the better acquain- 

 ted with Hones and mountains produced by 



cays of deflroyed lime, or in chalk-ftones. In the former 

 ftate, he favv them in the limeftone quarries near Gojlar, (LET- 

 TER xm. in a note) and remembers them to be noticed in Mr. 

 Abilgaard'i account of the Soeren-Klint in Denmark; in the 

 latter, they are common on our fhores and in our chalk pits. 

 In whatever ftate found, they contain a great variety of marine 

 (hells and productions; fuch as different echini tes and their 

 feathers, fmall peclinites, and fmooth bivalves, aflerias colura- 

 itares and various corals, fur.gites, madrepores, and retepores. 

 Belemnites are very fcarce in the flints ; fo too petrified bone<^ 

 and gloflbpetrae. However they are found, cochlites and am- 

 monites the Tranflator never obferved in them. Remarkable 

 it is, that the corals, whether fungites or aftroites, have a 

 fmgular tendency to be changed into common flint. This 

 the Tranflator obferved particularly in the uppermoft lime- 

 itone-bed of the Tonniefberg, on the road from Hanover to 

 Wetbergen in Germany, which is entirely calcareous, and con- 

 tains no flints, except a great variety of flintified branchy 

 ilrjated corals, afooites, and fungitei.
