          species of our [Hyssopus viz. neritoides?], & [Scrophularifs?]
 When I had the pleasure of seeing you, you
 specified the opinion that there was not a specific
 difference between them.  I however, flatter myself
 that when you examine & compare them, you will
 be inclined to think the diffence (which is important)
 will authorize a separation.  It is even more striking
 in the recent, than in the dried specimens; but ap-
 pears to me pretty obvious in the dried.  You will find
 I have endeavored to give the more prominent
 distinction in my catalogue.  I should be very
 glad to hear from you when you have looked
 over the bundle - & if your leisure permits, to
 have your free remarks & opinions on the above,
 or any other specimens which I have forwarded.
 I am extremely solicitous to correspond with, and
 derive instruction from those who have had better
 opportunities if comparing plants, than I have.
 I am every day discovering how imperfect my
 own knowledge is, - and find, in fact, that I am only
 on the threshhold of Botanical Science.  I have seen
 enough, however, to make me very desirous to enter
 the Temple; and it shall not be for want of incli-
 ation, or effort, on my part, if I fail.


      I wrote you a few lines some weeks ago, by mail, -
 which you have probably received - though I did
 not know your precise direction at that time,
 & mostly directed to New York.  I should be glad
 to hear if you have commencedd the Flora - & if not, when you
 calculate upon it.  - With great respect,
                                       I am, Dear Sir
                                       very sincerely yours
