THE ROYAL SOCIETY FOR THE ENCOURAGEMENT OF ARTS, MANUFACTURES, 

 AND COMMERCE welcomes the opportunity which has been afforded to it of 

 offering its warm congratulations and best wishes to the Royal Society on 

 the 250th Anniversary of its foundation. Among the many services which 

 the Royal Society has rendered to this country and to Science in general, 

 one not the least has been that in proportion as the increase of knowledge 

 has rendered necessary special and separate study of each branch of in- 

 vestigation, the Society has been instrumental in the formation of fresh 

 Associations for this purpose, while itself maintaining a general interest in 

 the whole field of progress and discovery. The Society of Arts, in whose 

 foundation a century and a half ago several Fellows of the Royal Society 

 took a prominent part, has from its commencement looked 'to the Royal 

 Society as the parent of such Associations in this country, no less than the 

 model for similar combinations abroad, and congratulates itself on the close 

 connexion between the two Societies, which has been maintained throughout 

 its existence by the presence in its ranks of many distinguished Fellows of 

 the Royal Society. The Council have had pleasure in deputing their CHAIRMAN 

 to represent them among the distinguished crowd of Delegates who have 

 come from all countries of the world to take part in the celebration of this 

 auspicious Anniversary, and they desire to express their earnest hope that 

 the future may have in store for the first and greatest of English Scientific 

 Societies achievements no less illustrious and beneficial to mankind than those 

 which are recorded in its past history. Sealed with the Seal of the Royal 

 Society for the Encouragement of Arts, Manufactures, and Commerce in the 

 presence of 



SANDERSON, Chairman of the Council. 

 H. T. WOOD, Secretary to the Society.
