SCIENCE. 



663 



(ii.) In each science the several subject- 

 entries shall be arranged under headings 

 corresponding to the registration numbers 

 on the slips, the which headings and num- 

 bers shall be those contained in the author- 

 ized schedules of classification. 



(iii.) The divisions indicated by registra- 

 tion numbers may be further subdivided by 

 means of significant words or symbols. 



(iv.) The nature of the subject entry 

 may vary. Thus, as suggested in the cases 

 of Mathematics and Physiology, it may be 

 the title only ; whilst in other sciences a 

 special entry, more or less different from 

 the title, may be provided on each'slip. In 

 all cases the number of subject-entries to 

 be copied from a slip shall be determined 

 by the number of registration numbers on 

 the slip. 



(v.) The mode of arranging subject-en- 

 tries under a registration number, or under 

 the subdivisions of a number afforded by 

 significant words or symbols, may vary. 

 They may either be arranged in the order 

 of authors' names placed alphabetically, in 

 which case the authors' names shall precede 

 the subject-entry in the Book Catalogue, or 

 they may be arranged either in an arbitrary 

 order or in some order suited to the partic- 

 ular series of entries. 



When in preparing an issue of the Book 

 Catalogue it is found that a registration 

 number has no entries collected under it 

 the number and corresponding heading may 

 be omitted from that issue. 



To each part of the Book Catalogue cor- 

 responding to an authorized schedule there 

 shall be appended an alphabetical index of 

 the headings, and, if expedient, also of the 

 significant words appearing in that part, 

 showing on which page of the part each 

 may be found. 



After the publication of the first issue of 

 the Book Catalogue the Director of the 

 Central Bureau shall consult the Commit- 

 tees of Eeferees as to the desirability of 



making changes in the classification, and 

 shall report thereon to the International 

 Council, who shall have power to authorize 

 such changes to be made as they may think 

 expedient. 



26. That the following recommendations 

 of the Royal Society providing for Interna- 

 tional Conventions in connection with the 

 Catalogue be adopted : 



Each region in which a Regional Bu- 

 reau is established, charged with the duty 

 of preparing and transmitting slips to the 

 Central Bureau for the compilation of the 

 Catalogue, shall be called a ' constituent re- 

 gion.' 



In 1905, in 1910, and every tenth year 

 afterwards, an International Convention 

 shall be held in London (in July) to re- 

 consider, and, if necessary, revise the regu- 

 lations for carrying out the work of the 

 Catalogue authorized by the International 

 Convention of 1898. 



Such an International Convention shall 

 consist of delegates appointed by the re- 

 spective governments to represent the con- 

 stituent regions, but no region shall be rep- 

 resented by more than three delegates. 



The rules of procedure of each Interna- 

 tional Convention shall be the same as 

 those of the International Convention of 

 1898. 



The decisions of an International Con- 

 vention shall remain in force until the next 

 Convention meets. 



27. That the following recommendations 

 of the Royal Society relating to the consti- 

 tution of an International Council, which 

 shall be the governing body of the Cata- 

 logue, be adopted : 



Each Regional Bureau shall appoint one 

 person to serve as a member of a body to 

 be called The International Council. 



The International Council shall, within 

 the regulations laid down hy the Interna- 

 tional Convention, be the Governing Body of 

 the Catalogue.
