          though I did not consider it necessary to quote him,
 for such an obvious feature of the plant.  this,
 to be sure, is a small matter: yet I always prefer
 that the exact truth should be known - especially
 where my own name is involved.  The general
 accuracy of your work is delightful, and highly
 exemplary.  I have no doubt, when your final
 corrections shall be made, that there will be
 little left to desire, in that respect.  Should I
 discover any thing, during its progress, that
 appears worthy of being noted for correction,
 or revision, I shall of course make it known
 to you, without reserve or ceremony.


 I am much gratified to find that
 Dr. Gray has consented to keep us au fait,
 in Botanical matters, through the medium
 of Silliman's Journal. That work had
 become as voluminous on my hands,
 and so small a portion of it devoted to
 Botany, that I ordered it to be discontinued, at
 the end of last year: but as soon as I heard
 of Dr. G's engagement, I immediately reserved my
 subscription, - and shall continue it so long as it shall
 furnish that desirable information. I have the entire
 sett - having been an original subscriber; and have
 often regretted that it was not, as far as practicable,
 made the exclusive vehicle of American Natural Science.
 It ought to be a kind of National Bulletin, - containing a
 summary of all that is doing by our contemporaries in the
 several departments of Natural History.  In that case, it would
 be more satisfactory - and more economical, too, (even if it
 had to be published monthly), than the present plan of
 multitudinous and independent Annals, issued by our
 various Acadamies, Lyceums, and other societies.


                      Yours sincerely,
                                     Wm Darlington
