Change in the plan of presentation. Publication of the current 

 portions of our " biochemical bibliography and index "^ has been inter- 

 rupted because of unavoidable delay in the issuance of this number of 

 the Biochemical Bulletin (page 270). The European war has also 

 afJected the bibliography and index, by reducing materially the Output 

 of papers in, and numbers of, the European publications on our Journal 

 list. This delay in publication, and the simultaneous curtailment of 

 content, have suggested an improved plan for the presentation of the 

 bibliography and index, which we inaugurate herewith, 



The chief improvement consists in the arrangement of titles in 

 subject-groups rather than, as heretofore, in the order of the place- 

 ment of the papers in the successive numbers of the respective Journals. 

 Each title is placed under the subject-head that is suggested by the 

 main feature of the content of the corresponding paper. Thus, papers 

 consisting primarly of descriptions of methods are indicated coUectively 

 under " Methods." This arrangement follows the general style of 

 that proposed by the senior author some years ago for the Biochemical 

 Department of Chemical Ahstracts, and which is still in vogue. The 

 advantages of this arrangement are so obvious that a mere Statement 

 of its adoption here is sufiEicient to suggest its purpose and its merits. 



Considerable space is saved by the use of small letters to indicate 

 particular volumes of the listed Journals. The position and signif- 

 icance of these letters are indicated below. 



The names of authors follow, in this new plan, the titles of the 

 papers, whereas, in the preceding issues, the reverse order was the rule. 



The bibliography and index remain practically unchanged other- 

 wise, both in style and scope.
