          In your last letter to me; referring to a plant
 found by Mr. Townsend & myself at the Hackensack,
 you ask, "are you certain respecting the Hedyotis
 glomerata which you found on the Hackensack?
 Could it have been the [illegible ramosior?] that
 you found?"  In reply, I have the satisfaction to
 assure you, that the plant is undoubtedly the
 Hedyotis; as I had previously received specimens
 from yourself, with which we have compared
 it - & the two are obviously identical.  Theree is
 plenty of it in a swamp thicket, on the right bank
 of the Hackensack, a few peches south of the [Tavern?]
 kept by a Mr. Vreeland, just over the bridge, on the road
 to Patterson.  The plant is very minute, in that lo-
 cality, compared with a specimen which I have
 (in fruit, however, & therefore older) from another quarter,
 either from Dr. Pickering, or some other correspondent.
 But it is just the size of some received from you.


     I hope you are still at work at your
 second volume, & that we may calculate on
 seeing it before very long.  We want something
 more complete & satisfactory than we now have
 to aid us in determinning our [illegible] plants,
 & some others.


     Have you any late advices from
 Dr. Gates, your Southern Explorer?  What are the
 last accounts of Prof. De Candolle's progress with
 the 4th Vol. Or Part, of his [Prod..?]  In our retire-
 ment, here, we cannot get the early news of the
 scientific world.  Be pleased to favor me with
 such as your proofs, when you can command that
 much time - & believe me to be


                       yours very sincerely
                          Wm Darlington
