Thursday, April 22:
Lovely day; outside the blossoms are opening, but Loldi ill; thus a worrying day for me. Claire writes that my mother is somewhat better, though not yet out of danger. R. manages some work.
In the evening, letters of Frederick II; during the day with the invalid and Loulou. Wrote out a letter to her father. He has given a concert for the Pope in Regensburg; my father was present at it!
