by about ninety species ; while in the United States the for- 

 mer class exceed the two latter by not more than fifty. We 

 may add, that in Great Britain (probably from the conjoined 

 effects of its northern latitude and insular position) the land 

 birds prevail over the water birds and waders l)y not more than 

 seven species. The ornithology of Great Britain and Ireland 

 yields at present 277 different kinds of birds, of which 142 are 

 land birds, and 135 are water birds and waders. The Conti- 

 nental countries of Europe possess about 120 species of birds 

 which do not properly belong to Britain, and a vast proportion 

 of which have never yet been known to visit our shores ; while 

 the common grouse, or moor-game, is our only exclusive pos- 

 session. 



The present volume of the Fauna Boreali-Americana con- 

 tains descriptions of 240 species. To these we may add twenty- 

 seven native to the north-west coast, as described by Pennant, 

 or more recently observed by Captain Beechey (but which did 

 not fall under the observation of the Land Expeditions) ; and 

 C. L. Bonaparte has enumerated thirty-six additional species, 

 which migrate northwards, from or through Pennsylvania, in 

 the spring, and may, therefore, though not observed by Dr 

 Richardson, be fairly inferred to breed in the Fur Countries. 

 Thus, the total number of birds hitherto ascertained to inhabit 

 these countries, that is to say, the American territories lying to 

 the north of the 48th parallel, may be stated as amounting to 

 303 species. 



We shall conclude by recommending very zealously to all 

 who take an interest in ornithological pursuits, a careful and 

 continued study of this very beautiful and scientific work. 



2. Principles of Geology. By Charles Lyell, Esq. F. R. S. 

 Vol. II. Murray, London, ia32. 



This volume, like the preceding, is very amusing,' and al- 

 though not entirely or principally geological, cannot fail to be read 

 with much pleasure by those who take an interest in the beauti- 

 ful subjects so well discussed by our intelligent author The 

 first eleven chapters are devoted to Zoology, in which are consi- 

 dered the vicissitudes to which species are subject. After an
