“ A vivid picture of tropical life, which may be read with unflagging interest, 
and a sufficient account of his scientific conclusions to stimulate our appetite 
without wearying us by detail. In short, we may safely say that we have 
seldom read a more agreeable book of its kind.”—Saturday Keview. 
SIR C. W. DILKE’S “GREATER BRI- 
TAIN.” A Record of Travel in English-Speaking Countries (America,

sand. Crown 8vo. 6s. 
The Times.— Sir Charles Dilke’s account of his tour in the West is 
delightful reading from first to last. Even when we differ from him, we are 
always ready to admit the industry of his research and the accuracy of his 
information, as well as his exceedingly clear way of stating his views. As a 
mere work of travel his book is exceedingly pleasant reading, and it gives 
One, ina comparatively small compass, an infinity of information of the sort 
one most cares to have. Above all, it is eminently suggestive, and what we 
should pronounce its highest merit is not so much the knowledge it com- 
municates as the craving it excites for more.” 
Saturday Review.—* Sir Charles Dilke has written a book which is pro- 
bably as well worth reading as any book of the same aims and character 
that ever was written. Its merits are, that it is written in a lively and agree- 
able style, that it implies a great deal of physical pluck, that no page of it 
fails to show an acute and highly intelligent observer, that it stimulates the 
imagination as well as the judgment of the reader, and that it is on perhaps 
the most interesting subject that can attract an Englishman who cares for his 
country.”
