If you should chance to see B. Koch, please say to her that it is not nice of her never once to have written to me. I wrote to her twice and three times to Malchus, but no answer. Say to her that if she doesn’t want to write she might at least urge Malchus to do so. In conclusion I venture a request; it is this: I should like once again to be so happy as to own a waistcoat knit of hare’s wool by your hands, my dear friend. Pardon the immodest request, my dear friend, but it proceeds from a great predilection for everything that comes from your hands. Privately I may also acknowledge that a little vanity is also involved in the request; I want to be able to say that I have something that was given me by the best and most estimable girl in Bonn. I still have the waistcoat which you were good enough to give me in Bonn, but it has grown so out of fashion that I can only treasure it in my wardrobe as something very precious because it came from you. You would give me much pleasure if you were soon to rejoice me with a dear letter from yourself. If my letters should in any way please you I promise in this to be at your command so far as lies in my power, as everything is welcome to me which enables me to show how truly I am Your admiring, true friend L. v. Beethoven. P.S. The V. [variations] you will find a little difficult to play, especially the trills in the _coda_; but don’t let that alarm you. It is so contrived that you need play only the trill, leaving out the other notes because they are also in the violin part. I never would have composed a thing of the kind had I not often observed that here and there in Vienna there was somebody who, after I had improvised of an evening, noted down many of my peculiarities, and made parade of them next day as his own. Foreseeing that some of these things would soon appear in print, I resolved to anticipate them. Another reason that I had was to embarrass the local pianoforte masters. Many of them are my deadly enemies and I wanted to revenge myself on them, knowing that once in a while somebody would ask them to play the variations and they would make a sorry show with them.
