Throughout this catalogue titles 'have been quoted in the language of the 

 publication as far as possible. In a very few cases titles in Japanese, 

 Russian, and Hindustani have been translated into English and one Greek 

 subtitle into Latin. In the case of the Japanese publications translitera- 

 tion of the original title has also been given. 



In the following periodical lists a number of publications not ordinarily 

 classed as periodicals have been included. All serial publications are 

 carried on the business records of the library as periodicals, and many 

 of these are used in such a way that it has not seemed well to make a 

 division here, hence all have been included. Practically all titles of serial 

 works appear also in the lists of books under their appropriate subject 

 classifications. 



Certain journals are frequently called for by the name of the editor e. </., 

 Koch's Jahresbericht, Grafe's Archiv, Hoppe-Seyler's Zeitschrift, etc. In 

 the alphabetical lists these have original entries which follow title page of 

 periodical, with cross references to other forms. 



For convenience in consulting periodical lists two arrangements, one 

 alphabetical and the other by subject, have been included in this catalogue. 

 In lists arranged by subject the titles appear according to the language 

 (or country) in which the periodical is published, in the following order: 

 American, English, German, French, other languages (or countries). Pub- 

 lications of learned societies follow regular periodical publications. Cross 

 references are not considered necessary in lists arranged by subject. 



In lists of complete sets of periodicals both inclusive volume numbers 

 and inclusive years of publication are considered worth giving, since 

 references to literature are far from uniform in this respect.
