JET. 62.] TO A. DE CANDOLLE. G35 



I offer my resignation unconditionally, that the 

 corporation may have, as it should, the whole matter 

 in its hands without embarrassment. If it be desired 

 to keep my name for the present upon the catalogue, 

 and especially if the corporation should prefer not to 

 place a permanent incumbent just yet in the Fisher 

 professorship, I would in that case take the liberty to 

 suggest that the present very capable and efficient 

 assistant, Dr. Goodale, be made adjunct professor of 

 vegetable physiology, with salary assigned from the 

 Fisher professorship. I remain, dear Mr. President, 

 Very sincerely yours, ASA GRAY. 



Messrs, the President and Fellows of Harvard College : 



HONORABLE AND DEAR SIRS, The time has 

 arrived when I may, as I think without detriment to 

 the university, retire from the professorship to which 

 I was appointed in the spring of 1842 ; and I hereby 

 tender my resignation of it, to take effect at the close 

 of the present academic year, when I shall have com- 

 pleted thirty-one years of service. 



I trust that I may still be useful to the university ; 

 and if agreeable to the corporation I should like to 

 continue to be Curator of the Herbarium. With sin- 

 cere regard, I am your obedient servant, 



ASA GRAY.
