Ntew YORK, June 22d, 1885. 

 MY DEAR SIR : 



I take pleasure in furnishing to Princeton Col- 

 lege my address presenting the memorial tablet of 

 Professor Henry. I have added to it an appendix 

 of notes supporting the statements contained in it, 

 which I trust will prove satisfactory. 



It is a labor of love for me to do anything 

 tending to present our great and beloved friend to 

 his own age, and to posterity, in his true propor- 

 tions. His achievements seemed to him so easy 

 to perform, that he never looked upon them as 

 exhibiting any great power ; and he therefore 

 involuntarily shrank from that praise to which 

 he was so eminently entitled, and from conspic- 

 uously exhibiting his results before the world. 

 He preferred to defer to the judgment of posterity, 

 and to submit his reputation to the ordeal of 

 time, which, like a simple acid, eats away the baser 

 metal, and leaves the pure gold free from its asso- 

 ciation. 



With many thanks to you for the compliment 

 implied in your request, 



I am, sir, very truly, 



Your obedient servant, 



EDW. N. DICKERSON. 

 President McCosn, 



Princeton College.
