 Dear Sir,


                I have collected & propose to forward to-
 morrow, to Mr. Prince, a few roots of the Euphorbia
 cestrica, or pennsylvanica or memoralis, or Darlingtorriana,
 or whatever else you may please to call it, when
 you shall have satisfied yourself that it is a non-
 descript species - which I strongly incline to think it is.
 I wish Mr. Prince to cultivate it, in his garden at
 Flushing; & I wish you to examine its habit & cha-
 racters, during growth, so that you may be enabled
 to decide, satisfactorily & conclusively, whether or not
 it is a new species.  If you have a garden of your
 own, perhaps you would prefer to have a root or two
 there, more immediately under your eye, then it
 will be at Flushing.  In that case, Mr. Prince will
 doubtless let you have them; & I trust there will 
 be no difficulty in getting them to grow. -
      Some time ago, i received a proof sheet of my note
 on the Prunus americana; and I suppose the number
 of the Annals, in which it is to appear will soon be
 published.  There were a few typographical errors in
 the proofsheet; but as they did not affect the sense 
 of the passages, I did not think it necessary to trouble
 the committee with a notice of them - and indeed I
 was in [illegible] they would be perceived without my
 indicating them.  I would be much obliged, if the
 publishing Committee could spare me two or three
 copies of the Number, & have them forwarded to Philadelphia
 for me, to the care of their Agent, or of Mr. J. Dobson, 108 Chestnut A.
 I wish to present one copy to our Cabinet; & another
 to the young lady who made the drawing for me.
