In the autumn of his marriage year, Mendelssohn paid his fifth visit to England, in fulfilment of an engagement to conduct his 'St. Paul' at the Birmingham Musical Festival of 1837, at which he also played the pianoforte and organ. He stayed (in London) at Klingemann's, 4, Hobart Place, Eaton Square. The house, which still stands, is opposite St. Peter's Church. During this visit Mendelssohn spent two whole mornings with his host on the "plan" of an oratorio of "Elijah." This "plan," or "sketch," was left with Klingemann for him to develop and to put "into verse." A few months afterwards he received the following letter:-- [MENDELSSOHN TO KLINGEMANN.] LEIPZIG, _January_ 9, 1838. "... Over all this chatting I am forgetting a very important affair. I received last week by post a parcel (which cost me nearly 10s. for postage), containing an English 'text' for an oratorio of 'Elijah,' which was sent to me by a Mr. Charles Greville (18, Vineyards, Bath, Somersetshire), in the name of the poet, with a strange letter. Do you know this gentleman, or the name of the poet, J. Barry, a clergyman? I have never heard of them.... I should like to know how they fixed on 'Elijah,' and on this way of treating the subject, which certainly resembles our 'sketch' very closely.... They have already dedicated their 'Elijah' to the Duchess of Kent, and no doubt will make much ado about it; and if I do not compose it, Neukomm, or some one else may do so. Therefore--you see what is coming--I beg you for two things: 1st, make our 'sketch' into verse and send it to me at once (you may take Bible words to help you, or whatever you like), so that I may compose it forthwith; and secondly, send me, in any case (even if you will not comply with No. 1), our 'plan' or 'sketch,' as we made it when last we met (with all remarks) _copied_, and write to me at the same time." The Rev. Mr. Barry's libretto of "Elijah," above referred to, was not published till 1869. A copy of the little book, now "out of print," is before me. Its title is:-- "ELIJAH, or the Baalim in Israel: a Metrical Libretto, in four parts, dedicated in the year 1838, by express permission, to Her late Royal Highness the Duchess of Kent. By the late Rev. James Barry, M.A., curate of Bratton Clovelly, Devonshire. Oxford and London: James Parker & Co., 1869." The Preface, signed "E.S.B.B.," states:--
