THE INTERNATIONAL CATALOGUE. 



At the end of last month the Smithsonian 

 Institution sent out a circular letter inviting 

 various bodies in America to subscribe for 

 a period of five years to the proposed Inter- 

 national Catalogue of Scientific Literature. 

 At an early stage of the deliberations con- 

 cerning the Catalogue, it became evident 

 that the necessary financial basis for the 

 undertaking could not be secured on the 

 plan of direct contributions from the several 

 countries interested in the matter. An 

 adequate basis however presented itself in 

 the form of guaranteed subscriptions for a 

 certain period ; and it was calculated that 

 a guarantee of subscriptions of about 300 

 complete sets would justify the work being 

 begun. The German government under- 

 took to subscribe for 45 complete sets for 

 five years ; other governments undertook 

 subscriptions of lesser amounts ; the Eoyal 

 Society guaranteed that 45 copies should be 

 subscribed for in Great Britain and Ire- 

 land ; and, at the close of the International 

 Conference, in June last, the financial pros- 

 pects were found to be such that if sub- 

 scriptions for 45 complete sets for five years, 

 in the United States of America, could be 

 assured, the work might at once be put in 

 hand. The Smithsonian Institution under- 

 took the task of asking for subscriptions ; 

 hence the circular in question.
