Provided always that when any addition 

 to or change of the schedule of classification 

 in any one branch may seem likely to 

 affect the schedule of classification of some 

 other branch or branches, the Committees 

 concerned shall have been consulted ; and 

 provided also that in all cases of want of 

 agreement within or between the Commit- 

 tees, or of other difficulty, the matter shall 

 have been referred for decision to the Inter- 

 national Council. 



All business transacted by the Commit- 

 tees shall be reported by the Director to the 

 International Council at their next ensuing 

 meeting. 



0/ the Regional Bureaus. 



15. In all countries in which, or where- 

 ever, a Eegional Bureau is established, as 

 contemplated in Regulation S (above), the 

 Regional Bureau shall be responsible for the 

 preparation (in accordance with Regula- 

 tions hereinafter laid down) of the slips 

 requisite for indexing all the scientific litera- 

 ture of the region, whatever be the language 

 in which that literature may appear. 



Each Regional Bureau shall transmit 

 such slips to the Central Bureau as rapidly 

 and as frequently as may be found con- 

 venient. 



In the case of countries in which no 

 Regional Bureau is established, the Central 

 Bureau, failing other arrangements, shall, 

 upon special mandate, endeavor to under- 

 take the work of a Regional Bureau.
