and sixty-two. It is the oldest scientific association in Great Britain, and 

 one of the oldest in the world. Among its fellows are included those of the 

 greatest scientific eminence in Great Britain; and by their indefatigable 

 activity in the realm of natural science and by their keen counsel, the Society 

 has wonderfully fulfilled its purpose. The institution, by the Society, of the 

 annual grants for the promotion of scientific research, and of awards of 

 various medals to those making important discoveries, has been of great 

 service to the progress of knowledge in physical sciences. The publications of 

 the Society are among the most useful agencies for encouraging and dis- 

 seminating scientific information throughout the world ; and by them Japan 

 has been greatly benefited. The Imperial University of Kyoto appreciates 

 highly the Society's cordial invitation to participate in the celebration of its 

 two hundred and fiftieth anniversary, and herewith commissions her repre- 

 sentative to attend the ceremony, paying honour to the Society's glorious past 

 and praying for its still more glorious future.
