PREFACE. IX 



revision of Bohemian titles of periodicals, and to John Fryer, LL.D., of 

 Shanghai, for a list of treatises in Chinese. 



To insure the greatest possible accuracy in the several languages I 

 secured the aid of linguistic experts. The Rev. Prof. Samuel Hart, D.D., of 

 Trinity College, Hartford, Conn , read the Greek and the Latin ; the Rev. 

 Martin Osserwaarde, of New York, read the Dutch ; Mr. Axel Moth, of 

 New York and Copenhagen, read the Danish, Norwegian, and Swedish ; 

 Signor Cesare Poma, Vice-Consul of Italy, of New York City, read the 

 Italian, Spanish, and Portuguese ; Mr. Louis Solyom, of the Library of 

 Congress, Washington City, read the Hungarian, Russian, Polish, Bo- 

 hemian and other Slavonic languages ; Mr. George H. Boehmer, of the 

 Smithsonian Institution, assisted me in the French and the German. The 

 proof-reading continued for twelve months, and matters were so arranged 

 that each expert saw titles only in the language or group of languages 

 which he engaged to read. To these gentlemen I am under great obliga- 

 tions for their assiduity, promptness, and fidelity to my interests. 



For the conception and contents of this bibliography I alone am 

 responsible ; its publication has been made possible by the liberality of 

 the Smithsonian Institution, to which I presented the manuscript compiled 

 as a labor of love.
