with the facts, were prepared for the results 

 displayed. Many preparations of an ana- 

 tomical nature were exhibited by others, 

 and many of an embryological character, 

 oftentimes under the microscope, attracted 

 deep interest. A series of beautifvilly 

 mounted heads of venomous and non- veno- 

 mous snakes, by E. L. Ditmars, gave an 

 excellent idea of their differences in denti- 

 tion and structure. 



On the whole, the exhibition maintained 

 the high standard established in former 

 years and gave instruction and pleasure to 

 between two and three thousand members 

 and their friends. Every possible courtesy 

 was extended by the ofiBcers of the Ameri- 

 can Museum, and the Academy is again 

 placed under a debt of gratitude to them. 

 Our thanks may also be expressed in this 

 place to the many friends whose contribu- 

 tions made the exhibition a success, and of 

 whom only a small part could be specially 

 mentioned above. J. F. Kemp, 



Chairman of Committee. 



SCIENTIFIC BOOKS. 

 The International Geography. By Seventy Au- 

 thors ; edited by Hugh Robert Mill, D.Sc. 

 New York, D. Appleton & Company. 1900. 

 Pp. 1088, with 488 illustrations. 

 The International Geography is a large, sin- 

 gle volume compendium of geography, rightly 

 named international, both from the standpoint 

 of scope, and from that of authorship. The 

 seventy authors who have co-operated in the 

 enterprise have been chosen from all parts of 

 the world, each to write on his own specialty, 

 so that the editor has secured the most eminent 

 help possible in each of the chapters of the book. 

 We find, for instance, that Sir John Murray 

 contributes a chapter, with the Editor, on the 

 ocean ; Professor Penck, a chapter on the 

 Austro-Hungarian Monarchy ; and Mr. H. O. 

 Forbes, a chapter on the Malay Archipelago, 

 all of which are but random illustrations, that 

 are typical of the work as a whole. 



The volume is divided into two parts, the 



first, of 122 pages, devoted to the Principles of 

 Geography, and the second, of 930 pages, to 

 Continents and Countries. In the second part, 

 each of the continents is considered in detail by 

 countries, and special chapters are devoted to 

 the Polar Eegions. The volume closes with an 

 accurate, inclusive, and very satisfactory index, 

 covering 35 pages. 



One reviewer has stated that perhaps no one 

 but the editor was personally qualified to re- 

 view adequately such an inclusive and complete 

 summary of the present geographical conditions 

 of the world, a remark with which many of us 

 will perhaps agree. No complete analysis 

 is, therefore, contemplated here ; but attention 

 will be given to certain special features of the 

 volume, first, as to its general usefulness, and 

 second, as to the special chapters on the United 

 States and North America. 



The present reviewer feels that the volume 

 under consideration ought to be of every day 

 use to nearly every advanced teacher of geog- 

 raphy in grammar schools, and to every trainer 

 of future geography teachers in normal schools 

 and colleges, and has introduced the volume 

 with satisfactory results in one large class of 

 school teachers studying geography. In this 

 volume teachers and all others who have need 

 of getting quickly in touch with the best in 

 reference to all countries, find that best, told 

 concisely, interestingly, clearly and effect- 

 ively. Supplied with a good atlas and this 

 volume, any teacher is well equipped as to op- 

 portunity for securing the best Information for 

 daily use. One of the particularly valuable 

 features of the book is that it is adapted to the 

 abilities of the audience to which it would ap- 

 peal. The editor and the authors are to be 

 congratulated in that they did not miss their 

 mark. 



The special chapters dealing with America 

 were written by Professor W. M. Davis, and 

 Mr. J. B. Tyrrell, formerly of the Canadian 

 Geological Survey ; Professor Davis writing on 

 North America as a whole, and Mr. Tyrrell 

 on the Dominion of Canada. In the chapter 

 on North America, Professor Davis starts out 

 with certain comparisons between North and 

 South America, and between North America 

 and Eurasia. Following this is a consideration
