          P.S. In your last, you have kindly offered to send us a
 portion of your duplicates of the autumnal plants
 of New Jersey.  You will very much oblige us, indeed,
 whenever you have specimens to spare, by sending any
 of those enumerated in a List of Desiderata,
 which I did myself the honor to forward to you
 in the autumn of 1828.  We are extremely anxious
 to increase our collection of American plants.
