          look for the performance of  the interesting task
 before you.  I hope all American Botanists
 will furnish you with every thing which they
 may suppose to be new - so that we may have
 the work as complete as possible.  It would
 be well to visit the Herbarium of the Philadelphia
 Academy occasionally in order to see if they may
 have any American plants which you
 have not.  Your title page says the Flora
 is to contain all known plants north of Mexico.
 Do you include Texas?  or do you consider that 
 as belonging to Mexico?  I have a good many
 Texan plants from Prof. Hooker, which have
 no names; & I fell anxious to see
 an account of them.  If you include
 Texas, of course I shall see it: but,
 if you do not (as I suppose you will not)
 I shall have to wait for information
 from another [illegible].  Prof. Hooker said
 he would describe them in his periodical journal;
 but I have seen no notice of them yet.  By the
 way, his journals seem to be short lived.  I have
 subscribed fro three of them - two of which
 soon terminated - & now I have just received
 a few numbers of the third - viz. Annals of Nat. Hist.
     With my best wishes for your health & prosperity,
                               I remain yours truly,
                                          Wm. Darlington

 P.S.  You have, of course, recieved Dr. Candolle's 7th vol.
 (or rather half vol.), which completes the Compositae. I have had
 [my copy?] some weeks.
