 ROYAL METEOROLOGICAL SOCIETY, desire to offer to the Royal Society our sincere 

 congratulations on the occasion of the two hundred and fiftieth Anniversary of 

 its foundation. We are deeply sensible of the pre-eminent position which the 

 Royal Society has always held in the promotion of natural knowledge, and of 

 the beneficial influence it has exerted upon the advancement of learning and 

 also upon the scientific development of the technical and industrial arts, by its 

 unceasing efforts. We recognize with especial satisfaction the support which 

 the Royal Society has afforded to the science of Meteorology, as exemplified

 and physics of the atmosphere. In congratulating the Royal Society upon 

 a long and brilliant record of past achievement we are assured that it will 

 continue in the future to take an -equally important part in the progress of 

 all branches of science.
