 ten by him to the President, Dr. Patterson, according to the 

 direction of the Society at the last meeting. 



A7n. Philosophical Society, Nov. 19, 1852. 

 Sir, — I am instructed, by the American Philosophical Society, to 

 express to you the sincere regret with which they have received the 

 announcement of your intention to decline being again a candidate for 

 the office of President of the Society; and to assure you of the affec- 

 tionate esteem which the members entertain for you, and their high 

 sense of the able, dignified and courteous manner in which you have 

 discharged the duties that have devolved upon you for several years, 

 as their presiding officer. Whilst they sympathize with you on the mo- 

 tives which have admonished you to decline being again a candidate, 

 they fervently hope that one of them, — " declining health," — may 

 soon cease to oppress you, and that you may be destined for many 

 years of healthful and happy enjoyment. 

 I have the honour to be, sir, 



Your obedient humble servant, 



ROBLEY DUNGLISON, 



Sec. Am. Phil. Sac. 

 Dr. R. M. Patterson, 



President of the Am. Phil. Soc, 



The Rev, Dr. Boardman, in pursuance of an appointment
