ITALY. LETTER XXIII. 3! I 



Mr. Allione has himfelf an exquifite collection 

 of dried plants, infects, and efpecially, petrifac- 

 tions and minerals, chiefly found in Piedmont and 

 Savoy, though foreign correfpondence has equally 

 procured him riches from abroad. The following 

 pieces feemed to me remarkably worth notice. 



1. Impreffions and petrifactions of fifties in 

 white fhivery argillaceous limeftone or marl, fimi- 

 lar to thofe of Pappenheim -, from Scappezano and 

 from Mondolfo, in the Roman ftate; alfo from 

 mount Libanon in Paleftina. 



2. Nummularii, round and flat, of a form like 

 the Cornua Ammonh , from ~Daubrig in Switzer- 

 land, proving that the Nummularii are a fort of 

 (hells. 



3. Petrified wood, worm-eaten by the Teredo ; 

 from the hills near Annone nel Contado d*Ajli in 

 Piedmont. 



4. A petrifaction fimilar to an ear of corn; 

 near Turin. 



5. Yellow fulphureous earth, or rather native 

 fulphur, in grains, mixed with fome earth from 

 Tortona in Piedmont. 



6. Native fulphur in fmall lumps, from fortona. 



7. FofTil wood, entirely changed into Jamellated 

 tranfparent felenites, incruftated with a flint-like 

 fubftance ; from La Morra and Alice in Piedmont.
