November, 1901. 



On behalf of the Council and members of the Manchester 

 Literary and Philosophical Society, we beg to offer our most 

 hearty congratulations to M. Berthelot on his completion of fifty 

 years of untiring scientific research — research extending over the 

 whole field of pure, applied and historical chemistry. 



Whether we regard the brilliant syntheses by which 

 M. Berthelot showed that the world of organic chemistry can be 

 built up from inorganic elements, or whether we have regard to 

 his researches which have made a science of thermo-chemistry 

 possible, we recognise that his work has not only been carried 

 out with marvellous ingenuity but has always been guided by 

 fundamental conceptions. 



This Society, of which Dalton and Joule were among the 

 chief ornaments, is proud to number M. Berthelot among its 

 members. 



We desire to offer M. Berthelot on this occasion our earnest 

 wishes that he may long enjoy his splendid activity and his well- 

 earned fame.
