'THE CHALK CLIFFS OF DOYEP ; A Geological and Pal^on- 



-1 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 

 lieculiar 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, 154, Strand.
