          Prof. [Professor] John Torrey, N. [New] York


 My dear Sir,


 Both your letters of 21st & 25th have been 
 exceedingly agreable to me for the good sentiments
 you express towards me. It will, surely, be a happy
 day that in which I shall have the pleasure to press
 your hand and converse with you on the subject 
 of our dear science. Long, very long indeed, since
 I had the pleasure to see you and I hope you 
 will not defer your visit to Philadelphia further
 than the present summer, which so far, however,
 is not very encouraging for a trip of amusement.


 I am much obliged to you, my dear sir, for the 
 copies of Bot.  of Beckwith & Pope's reports; I hope I
 shall not be forgotten for the Bot. of the Mexican
 boundary. Without depriving you of your own
 copies, one word of you to the Secretary of war,
 would, undoubtedly, procure me the whole volume
 of this report. I am always in expectation to
 procures in Wahsinton the 4 first vol. [volume] of reports.


 I have taken the best care possible of our friend
 Mr Buckley, with whom I was very much pleased.
