one who, for nearly three-fourths of a century, had led in many branches of 

 philosophy and useful learning. 



Resolved, That we recognise no boundaries, no political or civil divisions in 

 philosophy, but consider our eminent, distinguished and learned associate as 

 belonging to us, as well as to the whole scientific world ; and we are deeply 

 sensible of the irreparable loss we have all sustained in being deprived of his 

 further labors. 



Resolved, That his illustrious example ought to spur us on to the scientific

 of our continent. 



The resolutions were then adopted.
