SIR, 



I have the honor to acknowledge the receipt of your note 

 informing me of my election as an Honorary Member of the Essex 

 Institute. 



Permit me to return my thanks through you to that distinguished 

 association for such a gratifying compliment, and to regret that my 

 membership is likely to be of so little value to the Institute^ 



I am an old man ; and while I hope that I have lost no interest in 

 the agencies for human instruction and improvement, I can take 



little part in them. 



Very respectfully, 



E. It. HOAR.
