VI. — OF THE PEEPAEATION OF THE MATERIAL 

 EOE THE CATALOGUE. 



29. On and after January 1, 1901, or as 

 soon after that date as the International 

 Council may decide, the Regional Bureaus 

 shall ti-ansmit to the Central Bureau the 

 material to be indexed in the Catalogue, 

 arranged on slips. 



Unless otherwise ordered by the Interna- 

 tional Council — ■ 



30. The slips shall be of the character 

 prescribed by the Central Bureau, and (ex- 

 cept in the case of titles given in languages 

 which do not employ Roman script) the 

 entries thereon shall be either printed, type- 

 written or legibly written in Roman script. 



31. A.t the head of each slip shall be given 

 the letter and registration number indicat- 

 ing the science and subdivision of that sci- 

 ence under which the material referred to 

 on the slip is to be catalogued. 



32. Unless the International Council de- 

 cide otherwise, for each book or memoir to 

 be catalogued, the Regional Bureau shall 

 supply. 



1. At least one copy of the entry for the Authors' 

 Index, containing the material prescribed in Section 

 23 above. 



2. At least one copy of each entry for the Subject 

 Index, containing the material prescribed in Section 

 25 above, and Section 34 beloAv. 



The Regional Bureau shall retain dupli- 

 lates until the volume containing the entries 

 is published. 



33. A paper or book shall be entered in 

 the Subject Catalogue in more places than 

 one only when this is rendered desirable by 

 its scientific contents. 



No exact limits to the number of entries 

 to be allowed to single papers can at present 

 be fixed. This must be determined by the 

 Central Bureau, after adequate experience. 

 Until such limits are determined, if the 

 Central Bureau is of opinion that in the re- 

 turns made by any Regional Bureau the 

 numbers of entries to single papers do not 



correspond to the scientific contents, it 

 shall be its duty to intervene ; such inter- 

 vention, however, to be based, not on indi- 

 vidual cases, but upon an average. (Rep. 

 Comm., p. 3.) 



34. The International Council is in- 

 structed to direct the Central Bureau to 

 aim at keeping the total number of entries 

 in the Authors' and Subject Catalogues 

 within 160,000, and not to exceed 200,000 

 entries without the permission of the Inter- 

 national Convention. (See Appendix I.) 



[Lists of species (see 16 above) must be 

 reckoned according to the space occupied 

 as may be arranged by the Central Bureau.] 



The Central Bureau is therefore in- 

 structed to reject less important entries, if 

 this step is necessary to keep within the 

 limits above laid down. 



VII. — OF THE FINANCES OF THE CATALOGUE. 



35. Any Body which establishes a Re- 

 gional Bureau shall be termed a Contract- 

 ing Body. 



36. The number of copies of the cata- 

 logue due to each Contracting Body shall 

 be sent to that Body, or to the correspond- 

 ing Regional Bureau as such Body may 

 direct, and shall be disposed of by that 

 Body, by gift or sale, at its own discretion. 



37. The Provisional Committee referred 

 to at the end of paragraph 11 is instructed 

 to negotiate with the several Contracting 

 Bodies with reference to the sale in their 

 respective regions of copies other than those 

 subscribed for by the Contracting Bodies. 



38. The various Contracting Bodies shall 

 distribute the copies of the catalogue due 

 to them in their own constituent regions. 



39. Prices shall be fixed for the diiferent 

 volumes by the Central Bureau, and at the 

 request of any Contracting Body, conveyed 

 to the Central Bureau before a date to be 

 fixed by the Central Bureau in any year, 

 different numbers of the different volumes 

 may be supplied to it during that year, pro-
