To THE PRESIDENT AND COUNCIL OF THE ROYAL SOCIETY. WE, THE PRESIDENT 



AND COUNCIL OF THE BRITISH ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE, 



offer our cordial congratulations to the Royal Society on the occasion of the 

 celebration of the two hundred and fiftieth Anniversary of the foundation of 

 the Society. The British Association, since its birth in 1851, has been 

 constantly in close relations with the Society. The great majority, not only 

 of those who took the leading parts in the foundation of the Association, but 

 of those who have filled its presidential chair, besides many others to whose 

 earnest co-operation the success of its Annual Meetings has been due, have 

 been Fellows of the Society. We would express the hope that the Society 

 may continue to prosper, and may always maintain that pre-eminent position 

 which is the fitting reward of its labours. Signed on behalf of the Council : 



WILLIAM RAMSAY, President.
