^VB.E CHALK CLIFFS OF DOVER; a Geological and 



A Paleontological Description of the typical section of the English 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 descrip- 

 tion than the original and admirable paper by "William Phillips in the Geological Transactions of 1818. 

 The author's long and intimate acquaintance with this locality gives him peculiar facilities for pre- 

 s^enting 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 vrill 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, 154, Strand.
