THE CHALK CLIFFS OF DOVER ; A aeological and Falcon- 

 tological Description of the typical section of the EngUsh Upper Cretaceous 

 beds.— By S. J. Mackie, F.G.S., F.S.A. 



Of the beautiful and instructive section of the Chalk Strata at Dover, there 

 exists no other description than tlie original and admirable paper by "William 

 Phillips in the Geological Transactions of 1818. The author's long and intimate 

 acquaintance vs^ith this locality gives him pecuhar facilities for presenting in a 

 light and readable form a concise and accurate account of the White Cliffs of this 

 celebrated shore, and which he trusts will be thought worthy of being regarded 

 as a text-book generally for the chalk-districts of England. 



The proposed work will be illustrated by first-class woodcuts, and will be issued 

 to Subscribers at the price of Five Shillings. Subscriptions will be received by 

 • the Author, 156, Strand.
