are seldom found but in technical works, 

 where their meaning, if they have one that 

 is definite, is at once made evident." Hence 

 many local names, except those which have 

 found their way " into some sort of litera- 

 ture," are omitted. Yet, though arbitrary, 

 the author has tried to make his method 

 tend to utility. The longer articles consist 

 chiefly of descriptions of birds, with notices 

 of synonyms, and excellent papers on bird 

 anatomy. A map of the world on Mercator's 

 projection shows the bird regions and their 

 boundaries. 



A POPULAR HISTORY OF ASTRONOMY IN THE 

 NINETEENTH CENTURY. By AGNES M. 

 CLARK. Third edition. New York : 

 Macmillan & Co. Pp. 573. 



THE revision called for by the great num- 

 ber and importance of the astronomical dis- 

 coveries that have been made since the last 

 previous edition of this book was published 

 has been made with great care and pains, 

 and with the aim, not only of furnishing the 

 new information, but also of so completely 

 incorporating it with the pre-existing text as 

 to leave no gaps in the narrative suggesting 

 interpolations. The book has thus grown 

 and been brought down to date " by a pro- 

 cess of assimilation rather than of mere ac- 

 cretion." The foot-note references have 

 been multiplied ; the index has been made 

 more copious; the chronological table has 

 been considerably extended ; and several new 

 tables of data have been appended. 



THE ORE DEPOSITS OF THE UNITED STATES. 

 By JAMES F. KEMP. New York: The 

 Scientific Publishing Company. Pp. 802. 

 Price, $4. 



THE claim is made for this book that it 

 fills a vacancy in our scientific literature, for 

 no complete review of the ore deposits in our 

 country has appeared since the publication 

 of Whitney's Metallic Wealth in the United 

 States in 1854. Yet within the last forty 

 years enormous developments have been 

 made in new mining districts, the relative 

 importance of different regions has changed, 

 and great advances have been made in our 

 theoretical knowledge regarding the origin 

 and formation of ore beds. The present 

 work has been conceived with such consid- 

 erations as these in view. A twofold pur- 



pose is to supply a condensed account of the 

 metalliferous resources of the country which 

 shall be readable and serviceable as a text- 

 book and book of reference; and to treat 

 the subject in such a way as to stimulate 

 investigation and study of the phenomena. 

 The ore deposits are taken according to the 

 metals they yield. The treatment is geo- 

 logical, and the principles of origin have 

 been made prominent. To the descriptions 

 of others the author adds observations made 

 by himself in travel during the last ten 

 years. 



CAMP FIRES OF A NATURALIST. By CLARENCE 

 C. EDWORDS. New York: D. Appleton 

 & Co. Pp. 304. Price, $1.50. 



PROF. LEWIS LINDSAY DYCHE, of the 

 University of Kansas, enjoyed in his boyhood 

 and youth the life of a pioneer on the plains. 

 He lived in close communion with Nature, 

 among the animals and plants, and grew up 

 a naturalist. He acquired a school and col- 

 lege education largely by means of his own 

 efforts, was graduated from the university 

 at the head of his class, and became an as- 

 sistant and afterward professor of anatomy 

 and physiology there, of zoology and animal 

 histology, curator of the natural history mu- 

 seum, and director of the taxidermical work. 

 In the museum stands, according to Mr. Ed- 

 words, the finest collection of mounted ani- 

 mals in the world his creation. This book 

 is devoted to the relation of the story of the 

 incidents and adventures of his fourteen ex- 

 peditions after North American mammals. 

 It is taken from his note-books and diaries, 

 with nothing added to the facts he has re- 

 corded. The adventures are not of a thrill- 

 ing kind, but present the life of the woods 

 as it actually is, in a dramatic form, with 

 sketches of scenery and the life of the hunt- 

 ing camp, and information about the charac- 

 ter and habits of the animals hunted. 



SOCIALISM AND THE AMERICAN SPIRIT. By 



NICHOLAS PAINE GILMAN. Boston and 



New York : Houghton, Mifflin & Co. Pp. 

 376. Price, $1.50. 



THE development of socialism in the 

 United States is thoroughly discussed in the 

 thirteen chapters of this volume. Whether 

 the American spirit conforms to Mr. Gilman's 

 outlines is a doubtful matter. He may de-
