          I got a sight of Dr. Gray's Monograph of [illegible]
 through the kindness of Dr. Pickering; and was highly pleased
 with it.  You may give my compliments to Dr Gray, and tell him
 I have got the Atheropogon & Scirpus baldwinianum,
 for him. I shall take an early opportunity to send
 them, to your care.  I hope his in encouraged to go on
 with his laborious project.  It will be invaluable to
 the student; if he can get all our American grasses
 and Cyperaceae in it.  I wish you would inform 
 me whether you are finally satisfied that the Euphorbia
 [Sill...?] Journal, that you had described it by the name of
 E. Darlingtonicana. was that statement correct? If so, 
 I should be glad to see the description, before I
 reach the plant, in my progress.  Having made as
 many inquiries as may be convenient for you to
 answer at one time, I will conclude by renewing
 the appearances of the very great and sincere
 respect with which I am, Dear Sir,
                          your friend & obedt. Servt.
                                   Wm. Darlington


 P.S. I expect to go to Philadelphia on Wednesday next
 the 14th inst.  and take the package for Dr. Gray with me
 to Mr. Dobson's to be forwarded by the first opportunity.
 I have put it into it some specimens, for you of Veronica
 anagallis, which you requested; and also one or two of V.
 Beccaburga.  Your formerly express a wish to see the
 Tipularia, which I collected in Virginia.  I got nothing
 but leaves and roots; and of these I have put in two or
 three specimens for you.  I have also sent a few spec:
 imens or Erytheraceae pulchella; which was detected in this
 county, the present year.  I find it mentioned by no
 American Botanist but Muhlenbert; - though Dr. Pickering
 informs me he found it on the Eastern shore of Virginia;
 and he also says it is the same plant which Dr. Beck calls
