No 
                doubt I shall always be a very untidy correspondent where you 
                are concerned, seeing that, as it is, I am not a very diligent 
                letter writer. Well, you must just overlook this - I trust that 
                you have received my brother's letter in which he asked you to 
                draft the notice about the really extraordinarily numerous and 
                serious mistakes. In a few days I will send you a list of them. 
                The edition is so beautiful that it is most unfortunate that it 
                should have been launched into the world with that extreme slovenliness 
                and lack of care - Since you have engraved my variations from 
                my manuscript, I am also in a state of perpetual trepidation lest 
                a number of mistakes may have crept into them; and I should very 
                much like you to send me a proof copy beforehand. It is such an 
                extremely unpleasant experience, particularly for the composer, 
                to see an otherwise finely engraved work full of mistakes. In 
                the grand variations you have forgotten to mention that the theme 
                has been taken from an allegorical ballet for which I composed 
                the music, namely: Prometheus, or, in Italian, Prometeo. This 
                should have been stated on the title-page. And I beg you to do 
                this if it is still possible, that is to say, if the work has 
                not yet appeared. If the title-page has to be altered, well, let 
                it be done at my expense - One forgets such things here in Vienna; 
                and indeed one scarcely ever thins of them - The incessant distractions 
                and at the same time the great bustling activity all around tend 
                to make one very careless about such matters. Hence you must forgive 
                me for raising the point so late in the day.
                     As 
                to the question of a poem I cannot yet enter into any arrangement. 
                But when the work you have announced has been published, I should 
                like you to be so kind as to inform me, so that I my look around 
                for a poem - Don't forget about the variations, both about the 
                proof-reading and also about the title-page, provided that it 
                is still possible to carry out my instructions. - If I can be 
                of any use to you in Vienna, apply at one to 
                                                       your 
                most devoted servant
