24 CATALOGUE OF PHILOSOPHICAL APPARATUS, &c. 



Drawer 21. Chalk called by the Italians Scaglia, from Schio, Vicentin. 



Drawer 22. Chalk fossils from Gosau, in Austria. 



Regarded as intermediate between the Cretaceous and Tertiary rocks. 

 See Murchison and Sedgvvick's paper in the Transactions of the Geological Society. 



Drawer 23. Lower Cretaceous beds. Montagne de Fizs, Alps of Savoy 

 near Chamouni, with Ammonites and other fossils. 



See Studer, Geologic der Schweiz, vol. II. p. 91. 



Drawer 24. 



TERTIARY OR CAINOZOIC SYSTEM. 



Divided by Lyell into 



Eocene, containing only about 5 per cent, of existing species of shells. 



M eiocene, containing not more than 20 per cent, of living species. 



Pleiocene, containing more than 20 per cent, of living species, but a few that 



are extinct. 

 Pleistocene, none but existing species. 



In my arrangement I have not attempted to distinguish these several orders, but have 

 merely placed together the tertiary deposits of each country, as those of Italy, Sicily, England, 

 France, Germany, Switzerland, and Cuba. 



Drawer 25. Shells in a kind of volcanic tuff, Ronca, Vicentin. 



Drawer 26. Fossil fish, &c., Monte Bolca, Vicentin, and Cape Orlando, near 

 Naples. 



Drawer 27. Gypsum, and other rocks, with tertiary shells, Volterra, &c., 

 Tuscany. 



Drawers 28, 29, 30. Shells with the containing rock, chiefly belonging to the 

 pleistocene period, although capping the lofty hill of Castrogio- 

 vanni, the ancient Enna, in the centre of the Island of Sicily. 

 See my memoir on the geology of Sicily, Edinb. Phil. Journal. 



Drawer 3 1 . Coralline crag, or lower Pleiocene rock, with its shells. 



Partly fresh water, partly marine, Orford, &c. ; also red crag, or 

 middle Pleiocene, Walton, Suffolk, containing a series of shells 

 and other fossils from these strata. 



Drawer 3 2. Red crag ditto continued, and specimens from Sheppy.
