 labours of the accomplished Stopani. 



In the north of Europe, and corresponding to our own beds, they range 

 by Osnabriick, Miuden, Hildereheim, and the Island of Bornholm in 

 the Baltic, thus occupying an area from the South of Norway, to 

 Lombardy and Montpellier, in the South of France ; from Derry 

 and Antrim, in Ireland, the Severn and Axmouth on the west, to 

 Vienna, at the eastern end of the Bavarian Alps, on the east ; and I 

 doubt not from specimens I have examined from India, that the flanks 

 of the Himalayas possess them also. 



Let us then, from this remnant and insignificant outlier at Garden or 

 "Westbury Cliff, and to which I have merely drawn attention, learn to 

 estimate the value and importance of local sections, as linking us by 

 correlation and research to those distant and more completely developed 

 masses which constitute a fragment of the structure of Europe, and to 

 which we must refer for the solutions of certain jjroblems and connecting 

 links in time and space, and which the Severn Valley illustrates through 

 this one section, as well as other geological phenomena throxigh its length 

 and breadth.
