other volumes cheaper. The prices will probably range between 

 10 shilling's and 35 shillings per volume. 



28. It is desirable that the Catalogue bo sold to the general 

 public at as low a price as possible, provided always that it be 

 not sold at a price below that at which it is furnished to 

 Contracting Bodies. 



29. The first volumes that are issued will not contain an entire 

 year's literature, and in that case the price for these volumes 

 will be reduced. 



30. Each Regional Bureau is therefore requested to inform 

 tlie Central Bureau, as soon as possible, how many complete 

 sets of the Catalogue it will require, and how many additional 

 volumes of separate sciences. If the final prices of the volumes 

 are not fixed by that date the information will be regarded by 

 the Central Bureau as liable to correction when the final price

 schedules and alphabetical indexes prefixed to the vqlumes 

 allotted to it in return for its subscription printed in English, 

 French, German or Italian as it may prefer. 



" If no request is made to the contrary, the language of the
