We arrived here last evening & I found your favour of the 17th instant for which I offer you my sincere thanks—I had began to think that I was erased from your list.—I have now the pleasure of sending you a copy of my first volume of ornithological biography which I hope you will accept as a small memento of the high regard I have for your self & your talents.—My inserting your name was not a matter merely of duty but of great pleasure and believe when I say that I never will be ungrateful to anyone who has been kind to me.— We are going to Paris on Friday week & will be absent about a month—on the first day of August next we sail from Liverpool to America where I intend to beat the bushes once more—my peregrinations will extend in all probability & God willing to the Pacific Ocean into California etc—After my return I wish to settle in England somewhere, but where is yet undetermined.— I have felt much grieved at reading the article of yours respecting _French Naturalists_. I say _grieved_, because I am always so when I see men of superior talents employing their pen time and mind at sparring instead of peacably giving to the world those results of their investigations & experience at all times so desired by everyone bent on studying the wonderful laws & beauties of nature. I do not wish to read a _lecture_ to you but from my heart I am sorry you should be _à la joute_ [?] with any one & will conclude by sincerely hoping that you will have no more of this sort of warfare.— I am over head in business as you may well suppose after an absence of 8 months but will be most happy to hear from you. Have you heard from C. Bonaparte lately? Is he still at Rome? it is now two months since I heard from him.— Present our united kind respects to your good Lady, accept the same yourself & believe me your friend J. J. AUDUBON. 77 Oxford Street. It is interesting to notice that Swainson kept his promise about the woodpeckers, and in 1831 named one, which had been obtained from Louisiana, _Picus auduboni_;[106] although Audubon later repudiated it, saying that he believed it to represent only an immature state of the common Downy Woodpecker, he returned the compliment by dedicating to Swainson one of his warblers, _Sylvia_, now _Helinaria, swainsonii_.
