388 The American Naturalist. [May> 



survey for the years 1892 and 93, by the Director ; reports on the 

 Geological investigations conducted in central Ontario and southwes- 

 tern Nova Scotia by F. D. Addens and L. W. Bailey respectively ; a 

 contribution to the knowledge of the minerals of Canada, as shown by 

 chemical analyses, by G. C. Hoffman; and a report on mineral statis- 

 tics and mines, by E. D. Ingall and H. P. H. Brumell. 



The Director's report includes much valuable information concern- 

 ing the hitherto practically unexplored regions of the Labrador 

 peninsula, and the western coast of Hudson's Bay. 



Sketch maps of southern Keewatin, and of the south-western part of 

 Nova Scotia accompany the reports on those regions, and a number of 

 statistical diagrams show the progress of the mining indutries. 



Elementary Physical Geography. 3 — A new text book of phys- 

 ical geography has been long needed, so that this work of Mr. Tarr's 

 is well timed. The author divides the subject into three parts the Air, 

 the Ocean, the Land, giving the physiographic side more prominence 

 than is customary in works of this kind. The language is clear, the 

 illustration apt, and the information up to date. Each chapter is sup- 

 plemented by a list of reference books and an appendix contains 

 descriptions of meteorological instruments, apparatus and methods of 

 use, suggestions to teachers, and questions upon the text. 



The text is usually well illustrated with diagrams and reproductions 

 of photographs many of them new, while the addition of 29 plates 

 and charts completes a most attractive volume. We can recommend it 

 for use as the best text book for colleges before the public. 



Guide Zoologique.*— A reference book, published foi use during 

 the meeting of the International Congress of Zoology at Leyden in 

 1895. Brief accounts are given of the zoological courses offered in the 

 various schools of Holland, also of the Zoological institutions, gardens, 

 and societies. The fauna of the country is summarized by specialists, 

 the history of the domestic animals revewed, and a short account of the 

 fishing industry closes the zoological part of the volume. The final 

 chapter is devoted to the climate of Holland. 



The many maps and plates which are distributed through the book, 

 its convenient size, and the clear, concise language of the text, combine 

 to make an admirable guide book,
