'^rHE CHALK CLIFFS OF DOYEE ; a Geological and 



**- 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 

 description than the original and admirable paper by William PhUlips in the Geological Transac- 

 tions 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 Avhich 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.
