either a country or part of a country or several countries or parts of 

 countries, which can for this particular purpose be conveniently 

 grouped together. 



It is proposed that such Regional Bureaux shall be entrusted with 

 the task of preparing the slips required to completely index the 

 scientific literature of the regions committed to their charge. The 

 slips so prepared in the different regions will be regularly forwarded 

 to the Central Bureau in London, to be checked according to the sanc- 

 tioned schedules, and then printed, first in slip form and finally in book 

 form, for issue to the subscribers. 



Primary Slips. — The slips forwarded to the Central Bureau from 

 each region will be known as primary slips, and when these bear more 

 than one registration letter, or more than one subject-entry (indicating 

 that more than one subject is treated in the publication it refers to), 

 copies will be printed, with or without alteration in the arrangement of 

 the subject-entries, to permit the production of a full card catalogue 

 for each subject. Such copies of the primary slip will be known as 

 secondary slips, and will be prepared entirely in the Central Bureau. 



The Regional Bureaux will be responsible merely for the preparation 

 of the primary slips, each of which is to contain : — 



(i.) A Title-entry— giving the author's name and the full title of 

 the communication, in the original language alone if the 

 language be either English, French, German, Italian, or 

 Latin. In the case of other languages, the title will be, as 

 far as the Regional Bureau for India and Ceylon is con- 

 cerned, translated into English ; but the original title will 

 also be added, either in the original script, or translit- 

 erated into Roman script. The title will be followed by 

 every necessary reference, including the year of publication, 

 and such other symbols as may be determined. In the 

 case of a separately published book, the place and year of 

 publication, and the number of pages, &c, will be given. 



(ii.) Subject-entries — indicating as briefly as possible the principal 

 subjects to which the communication refers. Such subject- 

 entries will be given only in the original language of the 

 communication, if this be one of the five previously referred 

 to, but in other cases in India and Ceylon, English will 

 be used. 



The following specimens of primary slips prepared by the Royal 

 Society's Committee will serve as a guide to authors, who, it is hoped, 

 will assist the local committee in their preparation : —
