By a coincidence Schlesinger’s son, who had established himself in business in Paris, wrote to Beethoven on the same day and asked him if a third movement of the Pianoforte Sonata in C minor (Op. 111), which he was publishing, had not been forgotten at the copyists. He, like his father a little later, evidently suspected that they had not received as much music, measured in detached movements, as they had paid for; they missed a rondo finale! The incident may have amused, or (which is more likely) even angered Beethoven; but it can scarcely account for the fact that Beethoven resolved about this time to have nothing more to do with Schlesinger _père_. On July 26 he writes to Peters of Leipsic, with whom he has now entered into negotiations and to whom he has offered the Mass, “In no event will Schlesinger ever get anything more from me; he has played me a Jewish trick, but aside from that he is not among those who might have received the Mass.” When Beethoven was conducting the negotiations with Schott and Sons in Mayence which resulted in the firm’s getting the work, he recurred to the Schlesingers in a letter of January 22, 1824, and said: “Neither is Schlesinger to be trusted, for he takes where he can. Both _père et fils_ bombarded me for the mass, but I did not deign to answer either of them, since after thinking them over I had cast them out long before.” Beethoven’s threats were frequently mere _brutum fulmen_; the Schlesingers, _père et fils_, remained his friends to the end and got two of the last Quartets. Both Simrock and Schlesinger are now waiting for Beethoven to send them the Mass and the fee is waiting for the composer at Frankfort. Meanwhile negotiations have been taken up with a newcomer in the field, who, however, is but trying to renew an association which had begun more than 29 years earlier. Before entering upon this phase of the history of the Mass it seems well to dispose finally of the Simrock incident.[43] On August 22, 1822, Simrock wrote to Beethoven again. Beethoven’s answer followed on September 13 and, as it contains more than a mere implication why he refused to abide by his contract (a point that has been a matter more or less of speculation from the time when the negotiations ceased till now), it is given in full here: [Sidenote: AN APPEAL TO SIMROCK’S GENEROSITY] Baden, September 13, 1822. My dear and valued Simrock:
