6. Tertiary Formations. — The calcaire grossier of the hills 

 that overhang the town of Verona, and of many parts of the 

 Vicentine Hills, passes into dolomite. The loose calcareous 

 sandy beds that alternate with this calcareous rock also contain 

 magnesia. Marine shells in high preservation are found both in 

 the solid and loose varieties. 



It may be useful to repeat concisely, what has already been 

 stated more at large, that the following terms are applied indis- 

 criminately by many writers on the Continent to rocks which 

 ought to be kept distinct; viz. greywacke to beds of the new.- 

 red sandstone formation, as well as to the true transition rocks,-: 



Transition limestone, to the younger alpine hmestone, or 

 English magnesian limestone formation, as well as to true tran- 

 sition hmestone. » '^ "-^ 



Transition gypsum, to tbe saliferous gypsum of the new red 

 sandstone and magnesian Hmestone formation, as well as to that 

 ■which accompanies true greywacke. 



Pierre ii gryphite to lias. Calcaire a gryphite to magnesian 

 limestone. Jura limestone to oolite, Has, and magnesian Hme- 

 stone. Nagelflue to agglutinated gravel, Rigi puddingstone^ 

 and new red sandstone conglomerate.
