DAHLMANN.— HISTORY OF THE ENGLISH REVOLUTION. 
By F. C. Dahlmann, late Professor of History at the University of Gottingen. Translated 
from the German, by H. Evans Lloyd, Svo. 10*. 6rf. cloth. 
Professor Dahlmann'' s book is, in short, a rapid sketch of the whole of what we call the 
Modern History of England, from its start at the Coronation of Henry the Seventh, to its 
intermediate settlement at the Coronation of William the Third. We have no English sum- 
mary of the history it relates so brief, compendious, and impartial. M. Dahlmann is a very 
earnest us well as intelligent writer ; and the steady advance of the popular principle in 
England, through an almost uninterrupted march of two centuries, is startlingly reflected in 
his clear and transparent relation. Mr.Lloyd''s translation is very well executed." — Examiner.

DE CUSTINE.— RUSSIA. 
By the Marquis De Custine. Translated from the French. 2d Edition. 3 vols, post Svo. 
31*. 6rf. cloth. 
'* We are inclined to think—and it is a painful reflection— that Mons. De Custine''s remark- 
able volumes contain a more accurate account of the state and condition of Russia than any 
other work of recent date, without exception. The author hasmanifestly penetrated through 
that superficial glitter and gorgeous array which have blinded the eyes of too many travellers 
to the imperfections and defects of this great empire, and has shewn it as it really is. To do 
this in the case of Russia requires maiiy and favourable opportunities of observation, con- 
siderable shrewdness, and a courage and determination not easily to be daunted; all which 
Mons. De Custine has proved himself to have possessed in an eminent degree; and the result 
is, a work which those who are desirous to know Russia as it really is, and not as it would fain 
impose itself on the world to be, would do well to consult. We promise our readers equal 
surprise and pleasure fromthe perusal of his very clever JooA."— Gentleman's Magazine.
