ROYAL SOCIETY OF EDINBURGH 



To THE ROYAL SOCIETY OF LONDON. THE PRESIDENT AND FELLOWS OF THE 

 ROYAL SOCIETY OF EDINBURGH desire to offer their congratulations to the 

 Royal Society of London upon the attainment of the two hundred and 

 fiftieth Anniversary of its foundation. Founded for the purpose of ' further 

 promoting by the authority of experiments the science of natural things and 

 of useful arts', the Royal Society of London has with increasing zeal and 

 power continued to fulfil its high calling, and commands in the world of 

 scientific endeavour a position peculiarly its own. The Royal Society of 

 Edinburgh recalls with pride and satisfaction that since its own foundation in 

 1783 there has always existed between the two Societies a close association, 

 based not only on community of aim and interests, but in great measure 

 also upon community of membership. Scientific men of eminence have served 

 on the Councils, and contributed to the publications", of both Societies ; 

 and each Society can claim the late Lord Kelvin as one of the most renowned 

 of its Presidents. At this time the personal connexion is happily exemplified 

 by the fact that the distinguished President of the Royal Society of London 

 has been a Fellow of the Royal Society of Edinburgh for fully half a century. 

 May the important work which the Royal Society of London has achieved 

 in the past be continued and extended, during many centuries to come, to 

 the furtherance of natural knowledge and the progress of humanity.

 tion at the courteous invitation to take part in celebrating the two hundred 

 and fiftieth Anniversary of the foundation of the Royal Society of London, 

 and our heartiest congratulations on the uninterrupted and pre-eminently 

 fruitful activity of the Society over a period of such duration. Scientific 

 Societies and Learned Bodies of all nations are bound and indebted in many 

 ways to the Royal Society ; for leadership in scientific thought, for encour- 

 agement of research, and for an unsparing hand in the dissemination of 

 knowledge. Since its inception the history of the progress of the Royal 

 Society has been largely the history of the advancement of science : the long
