She talks of the burning of the Judengasse, and reports on the state of the roads and their former home, Frieburger gaße which was also burned down. The situation is, she notes, fatal and threatening. She concludes by saying that almost all of her friends have emigrated so she is usually at home, playing the piano or reading. She notes that she is especially enjoying Voltaire’s Essai sur les mœeurs et l’esprit des nations.
