          In your former letter, you mentioned de Candolle's
 Synopsis as a work which you thought I probably
 possessed. Mr. de Candolle informed me, some time
 ago, that he was about to publish such a work,
 but I have never been so fortunate as to meet
 with it. If you know of any Bookseller in New
 York who probably has a copy, you would oblige me
 by informing me, so that I may send for it. I
 requested Mr. Schweinitz to endeavor to procure for 
 me Mr. de Candolle's large work, as far as it was
 published, during his stay in Europe, but I should
 be very glad to get the Synopsis in the mean time.
 I will now bring this hasty spittle to a close
 by requesting you to present my respectful
 compliments to Col. Thayer, Maj. Worth,
 and the other Professors and gentlemen whom
 I had the pleasure to become acquainted
 with during my visit to West Point
 in 1823 and assuring you that I 
 am with great respect your
 friend and obedt. [obedient] servant,


 Wm [William] Darlington
