THE CHALK CLIFFS OF DOVER; A Geological and Palffion- 
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 
Philhps in the Geological Transactions of 1818. The author's long and intimate 
acquaintance with this locality gives him peculiar facOities for presenting in a 
light and readable form a concise and accurate account of the White Cliffij of this 
celebrated shore, and which he trusts will be thought worthy of being regarded 
aa 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.
