Dear Monsieur Bonfantini,
For the moment we are at the end of the manuscript, and I cannot fix the exact time when the work will be taken up again. Let us now see whether the remaining manuscript gives you enough to make up a third volume; I would like to finish it here, which seems very convenient if we get almost to the 300th page.
Your very devoted
Richard Wagner
