Most valued friend,
Fritzsch has not given me the slightest intimation of anything I was to impart to you, and I am inclined to believe that the passage you quote was only used as a means of shifting his own embarrassment on the subject to your shoulders. My own pecuniary relations to Fritzsch were determined, quite accidentally, by the opportune appearance of my quasi-festival essay on Beethoven, and by the tremendous sensation created by my essay on the Jews, which would naturally react favorably upon my other publications and justify expectations of an immediate and rapid sale. Much will depend upon your ideas in regard to the sale of your book. If you are confident of good results, you will be guided by my views, well known to you, as to the relation between the size of the edition and the corresponding terms of payment in making your arrangements with Fritzsch.
In any case it would be advisable to have a complete agreement on this point, so that the relations would be determined once for all, so soon as anything had been accepted for publication, and that quite regardless of the "business" success. You will find this a much better plan than having it made to appear, each time an agreement is reached (as was the case with me!), that never before since the world was created had a book been accepted for publication.
Good luck to epigraphs and Plato; the latter is also being studied in Tribschen. We are all fairly well and send cordial greetings.
