Yesterday (Monday, the 23d), at four o’clock in the afternoon, we arrived here, thank God! safely, having been nine days and a half on our journey.  We thought we really could not have gone through with it; in my life I never was so wearied.  You may easily imagine what it was to leave Mannheim and so many dear kind friends, and then to travel for ten days, not only without these friends, but without any human being—­without a single soul whom we could associate with or even speak to.  Now, thank Heaven! we are at our destination, and I trust that, with the help of God, all will go well.  To-day we are to take a fiacre and go in quest of Grimm and Wendling.  Early to-morrow I intend to call on the Minister of the Palatinate, Herr von Sickingen, (a great connoisseur and passionate lover of music, and for whom I have two letters from Herr von Gemmingen and M. Cannabich.) Before leaving Mannheim I had the quartet transcribed that I wrote at Lodi one evening in the inn there, and also the quintet and the Fischer variations for Herr von Gemmingen [author of the “Deutsche Hausvater"], on which he wrote me a most polite note, expressing his pleasure at the souvenir I had left him, and sending me a letter to his intimate friend Herr von Sickingen, adding, “I feel sure that you will be a greater recommendation to the letter than the letter can possibly be to you;” and, to repay the expense of writing out the music, he sent me three louis-d’or; he also assured me of his friendship, and requested mine in return.  I must say that all those who knew me, Hofrathe, Kammerrathe, and other high-class people, as well as all the court musicians, were very grieved and reluctant to see me go; and really and truly so.

We left on Saturday, the 14th, and on the previous Thursday there was an afternoon concert at Cannabich’s, where my concerto for three pianos was given.  Madlle.  Rose Cannabich played the first, Madlle.  Weber the second, and Madlle.  Pierron Serrarius (our “house-nymph”) the third.  We had three rehearsals of the concerto, and it went off well.  Madlle.  Weber sang three arias of mine, the “Aer tranquillo” from the “Re Pastore,” [Footnote:  A festal opera that Mozart had composed in 1775, in honor of the visit of the Archduke Maximilian Francis to Salzburg.] and the new “Non so d’ onde viene.”  With this last air my dear Madlle.  Weber gained very great honor both for herself and for me.  All present said that no aria had ever affected them like this one; and, indeed, she sang it as it ought to be sung.  The moment it was finished, Cannabich exclaimed, “Bravo! bravissimo maestro! veramente scritta da maestro!” It was given for the first time on this occasion with instruments.  I should like you to have heard it also, exactly as it was executed and sung there, with such precision in time and taste, and in the pianos and fortes.  Who knows? you may perhaps still hear her.  I earnestly hope so.  The members of the orchestra never ceased praising the aria and talking about it.
