REVIEWS.

Derbyshire is 241; of these 77 are residents and 69 are regular migrants, 
33 of which breed in the county. The classification and nomenclature used 
is that of “ Saunders’s Manual of British Birds.” There are four illustrations 
of Derbyshire scenery, two of birds—one, very beautiful, of a white variety 
of Corncrake—and a map of the county. The index, as far as tested, is quite 
accurate ; printing and paper are sufficiently good. Messrs. Whitlock and 
Hutchinson must be heartily congratulated on having made a valuable 
addition to ornithological literature. A. B. B. 
La Terre avant VApparition de VHomme. Par Fernard Priem, Professeur au 
Lycee Henri IV. Paris: Librairie Bailli&re et Fils. 
This is the first division of an addition to Brehm’s celebrated series of 
popular scientific works “ Merveilles de la Nature,” and promises to be a very 
attractive work on general geology. It is appearing in twenty-four weekly 
parts, price fifty centimes each; and also in four larger divisions, three 
francs each. The author, apparently basing his work largely on Neumayr’s 
“ Erdgeschichte,” endeavours to give an account of the geology of all regions of 
the earth in a style which will be interesting to the general public, by 
describing the generalisations of the science without insisting on details, 
which, although the base of it, are yet uninviting to the non-geological reader. 
Judging from this first instalment, Professor Priem will succeed admirably, 
as he discusses the various important topics in the most lucid way, while 
there are numerous beautiful illustrations. These first 190 pages of the 760 
which will form the complete work, treat of such subjects as Fossils; 
Geological Periods ; Physical Conditions of Ancient Geological Periods; the 
Primitive Bocks; the First Continents ; and the various systems up to the 
Jurassic. The illustrations are of fossils, important geological sections, and 
scenery geologically interesting. 
To those who can read French easily, we strongly recommend this work ; 
it is very clearly written, and will put the reader in possession of the chief 
and latest generalisations not only of English geologists but also of such men 
as Suess, Neumayr, Bertrand, and other continental workers, which have not 
yet found their way into the ordinary English text-books. There is no work 
of a similar scope in English, except, perhaps, the newly-published “ Story 
of our Planet,” by Professor Bonney, which is considerably more than twice 
the price of this book. Any intelligent reader, even though without the 
slightest knowledge of geology (if there are any such in these days of Board 
Schools and University Extension Lectures) will enjoy it; while the student 
who knows only the smaller English text-books will obtain from it a broad 
December, 1893.
