EXECUTIVE SESSION, 12.15 P.M. 
President SMITH in the Chair. 
Dr. Hays, by unanimous consent, offered the following pre- 
amble and resolution, which were unanimously adopted : 
“Tnasmuch as the two hundredth anniversary of the birth of 
Benjamin Franklin occurs in January, 1906, it is proper that 
the American Philosophical Society, which owes its existence 
to his initiative and to which he gave many long years of 
faithful service, should take steps to commemorate the occasion 
in a manner befitting his eminent services to this Society, to 
science and to the nation. ‘Therefore be it 
“ Resolved, That the President is authorized and directed to 
appoint a Committee of such number as he shall deem proper 
to prepare a plan for the appropriate celebration of the bi- 
centennial of the birth of Franklin, and to report the same to 
this Society.”
