THE CHALK CLIFFS OF DOYEP ; A Geological and Palseon- 

 tological 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 

 description than the original and admirable paper by William Phillips in the Geological Trans- 

 actions of 1818. The author's long and intimate acquaintance with this locality gives him 

 peculiar 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 

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



The proposed v/ork will be illustrated by first-class woodcuts, and will be issued to Subscribers 

 at the price of Five ShilUngs. Subscriptions will be received by the Author, 154, Strand.
