36 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [NoV. 29. 



to our knowledge of the geology of Nice accruing from the observa- 

 tions of the Marquis L. Pareto, Prof. A. Sismonda, and Prof. A. 

 Perez. 



The views of the last-named gentleman especially, by whom the 

 proofs of the identity of the divisions of the cretaceous series in that 

 region with those of England have principally been obtained, were 

 brought forward by the author in this communication. 



Prof, Perez has studied the structure and succession of the rocks 

 of this district in great detail, and accumulated a large series of 

 fossils ; but his only publication on the subject hitherto has been a 

 summary of his observations, read before the Italian Association at 

 Genoa in 1846. Major Charters, having seen many of the principal 

 sites along with Prof. Perez, and conversed much with him, concurs 

 fully in his views. 



Major Charters described the topography of the district, with its 

 three river-basins and its numerous mountains, and then noticed the 

 geological formations in the following order : — 1 . Postpliocene 

 (quaternaria of the Italians) ; 2. Pliocene; 3. Eocene; 4. Creta- 

 ceous ; 5. Jurassic, including the Dolomite. 



This memoir had special reference to the following points of in- 

 terest : — The separation and definition of the nummulitic and the 

 cretaceous rocks ; the subdivision of the latter ; the association of 

 the gypsum of the Hill of Cimies with the cretaceous series ; and the 

 intimate relation of the dolomite with the Jurassic series. 



Major Charters also mentioned his visit to a volcanic district 

 about ten miles west of Nice.
