Biologists throughout the world are greatly 

 indebted to the German Society of Zoologists 

 and to the enterprising firm of Friedlander & 

 Sohn in Berlin for this very substantial aid to 

 research. The first edition of this zoological 

 directory was issued in 1895, and a supple- 

 mentary volume in 1901. The decade that has 

 passed since the last supplement was pub- 

 lished has brought many changes in the per- 

 sonnel, distribution and lines of interest of 

 the biological contingent of the scholarly 

 world, so that this new edition is particularly 

 welcome at the present time. The work gives 

 the correct address, ofiicial or educational con- 

 nections and specialty of nearly 17,000 per- 

 sons having professional or sufiicient amateur 

 interests in some field of biology to justify 

 their inclusion in a list of zoologists. The 

 names of a few of the leading booksellers, 

 dealers in animals, and supply houses are in- 

 cluded, but this element is far from complete. 

 The lists also include, as before, the titles of 

 the various natural history societies, mu- 

 seums, academies, etc., with ofiicial address, 

 name and address of the secretary, and titles 

 of serial publications with the date of the ini- 

 tial volume, a feature of great value to librari- 



ans, bibliographers and to the exchange service 

 of scientific organizations conducting publica- 

 tions. 



A new feature in the present volume is the 

 inclusion of the addresses of all the various 

 European organizations for bird protection, 

 and of the local clubs of entomologists, or- 

 nithologists, and other amateur organizations 

 of naturalists. In Berlin, for example, wt 

 find the " Hertha," " Nymphaea alba " and 

 " Triton " Vereine f iir Aquarien- und Ter- 

 rarienkunde, each with its stated hotel or 

 restaurant where its social gatherings are 

 held. The abundance of such organizations 

 in Germany and Great Britain stands in 

 noticeable contrast to their rarity in our own 

 country. This contrast is, in a manner, an 

 index of the smaller interest taken in this 

 country in the study of animals, as a result 

 possibly of the absence of instruction in nat- 

 ural history in our secondary schools and uni- 

 versities and of the predominance of the com- 

 mercial spirit. 



As an original document in the history of 

 the biological sciences this volume is of par- 

 ticular interest as it marks (in a unique fash- 

 ion) the progress of the growth of interest 

 throughout the world in biological matters. 

 The edition of 1895 contained about 12,000 

 names as over against the 17,000 of the pres- 

 ent one. The supplementary volume of 1901 

 is too incomplete for comparison. 



The work is international in scope and the 

 growth here indicated is shared by all nations, 

 though somewhat unequally. The increase in 

 names is approximately fifty per cent, in the 

 past fifteen years. The greatest gains, com- 

 puted on the basis of pages devoted to the 

 countries in question in the editions of 1895 

 and 1911, have been made in those countries 

 which were in the lead in the earlier years. 

 Thus, for example, Germany makes a gain of 

 128 per cent.. Great Britain, the United 

 States, Austria, Switzerland, exhibit gains of 

 80 to 90 per cent., while Russia, Belgia, Den- 

 mark and Canada show even larger growth, 

 100 to 110 per cent., and Japan the unsur- 

 passed record of 170 per cent. The Latin 

 countries have smaller increments to their
