an account, accompanied by diagrams, of the geological features of the 
Dordogne district, and descriptions and figures of the stone and bone imple- 
ments found in the caverns. 
Mr. Page is a well known and favourite geological teacher, and the highest 
praise we can award his present popular treatise is to say that in point of 
style and accuracy it is not below anything he has hitherto produced. It is 
just such a book as the general reader may peruse with pleasure and profit. 
In every instance where it has been possible, the author has avoided the 
technicalities of geology, while he has attempted to lay down the great 
problems of the science in language intelligible to any ordinarily well-educated 
person. There is one failing which we notice, and that is, the absence of illus- 
trations. No scientific work should be unillustrated ; and this rule holds 
good in an intensified degree for geology. The recent discoveries have not 
been neglected by Mr. Page, who gives a general account of Eozoon, and 
states his objections to Professor W. King’s startling hypothesis. 
The geological map of England and Wales has been prepared by Professor 
Ramsay, and is creditable alike to him and to its enterprising publisher. It 
is on the scale of ten miles to the inch, and besides giving numerous expla- 
natory sections, has all the recent railways marked out upon it. Forming a 
most convenient pocket volume, it should be in the possession of every 
working geologist. 
Professor Nicol’s little book is the report of two lectures, in which he 
shows that he deserves the credit of tracing the connexion of the metamorphic 
strata of the Grampians with the Silurian deposits 'in the south of Scotland. 
It has a bearing upon some questions of importance, and should be read by 
those who are acquainted with Professor Harkness’s views. 
THE ATLANTIC TELEGRAPH.* 
T HE beautiful volume before us is a fitting record of the great labour 
which last year saw begin and terminate. It is the history of the 
voyage, written by Dr. W. H. Russell, and while it is instructive and interesting 
as a narrative, it is highly ornamental as a sketch-book. Messrs. Day and 
Sons have reproduced Mr. Dudley’s drawings in the best style of chromo- 
lithography, and altogether the book is one of which it would be hard to 
speak too favourably. Dr. Russell gives an account of the earlier efforts to 
unite the old and new continents, and shows us that the first submarine 
telegraph cable projected on the other side of the Atlantic was the scheme of 
an English engineer. The melancholy circumstances attending the rupture 
of the cable are conveyed as only Dr. Russell is capable of conveying 
them. Every little incident in connection with the great project is 
sketched with minuteness, and the reader’s attention and sympathies are 
excited and engaged by this fascinating writer. Perhaps the most note-
