scientific institutions, the Royal Society has suggested the foundation of 

 'the International Association of Academies', and has thus enhanced the 

 prospect of establishing solidarity within the domains of scientific research

 the fundamental ideas this illustrious Society has given to the world merit 

 the admiration and gratitude of all, especially of the scientific institutions of 

 all countries. The Royal University of Norway therefore begs to express its 

 gratitude for the weighty contributions your Society has yielded to the 

 common work of culture, and tenders heartiest greetings and congratulations 

 on the occasion of your 250th anniversary, coupled with best wishes for ever 

 increasing prosperity.
