 following Report: 



The interest, which many members of our Academy have shown 

 in the issue of the second International Catalogue Conference, held 

 in Londen from Oct. 11"^ to 13«'^, as well as the circumstance that 

 our Academy has declared itself willing to contribute towards the 

 part, which the Netherlands are to take in tho work, being well 

 executed (sec the Proceedings of the ordinary meeting of Nov. 28''' 

 1896), have induced me here to give a short account of what has 

 been done since the holding of the first conference, in July 1896.
