          together, conveniently, by laying them aside as I find
 them, during the process of the new arrangement.
     I hope you will have the good fortune to meet
 with the distinguished Botanists, who are now laboring
 so successfully in that department of Natural Sciences
 in the countries you are about to visit: and also that
 you will have opportunity & leisure to examine
 satisfactorily their valuable Herbariums.  I almost
 envy you the pleasure of an interview with
 such men as Prof. Hooker & DeCandolle,Lindley
 & Robert Brown.  May you enjoy every gratification,
 in that report, which I can imagine but which,
 also, I am destined only to be permitted to imagine.


     In case you meet with Mr. DeCandolle, at Geneva,
 I wish, if you think of it, you would inquire
 whether he ever received from me a package of
 plants, which I forwarded to him in the year 1827.
 I sent him upwards of 100 species  in that year; &
 the year preceding I sent him a copy of my catalogue,
 with a letter each time; but having heard nothing
 from him, I have been apprehensive both packages
 have miscarried.  Could you not do me the favor, while
 at Geneva, to write me a letter, detailing interesting par-
 ticulars of the age, appearance & other circumstances and
 characteristics of that distinguished Botanist?  Nothing could
 be more gratifying than some account of such a man,
 whom I know only by his general fame & reputation.
     Wishing you most sincerely a prosperous voyage,
 & a happy return, with your family, - I remain , Dear Sir,
                                        Yours truly,
                                            Wm. Darlington
