It is still very cold, snow lying on the ground (in the parks), which is rare in London. I have just had a little note from Princess Mary, asking me to come and see her on Sunday at White Lodge, as she leaves early in the week for the Riviera. Wolff came in late to ask me if I would take him out to White Lodge, as Princess Mary had also written to him to come. He had his violin, so he played for about an hour, and most enchanting it was. I occasionally forgot about the accompaniment, listening to his beautiful long notes. He didn't mind, was standing in the middle of the room (playing by heart) and went on quite serenely until I caught him up somewhere and went on again. I dined quietly with Jean (as W. had a man's dinner at one of the clubs) and we made music all the evening. She is very busy translating a German book, Lady Blennerhasset's "Life of Madame de Stael." It looked easy at first, but I fancy is rather a formidable undertaking, as Lady B. has a very distinct style--very German, and I should think it must lose in translation. She had rather come to grief over one page. I looked over it, and said I didn't find it _very_ difficult, and I know German well, upon which she replied, "Please read it out to me, then, in good English." I began, but came to grief at once. I had got the meaning right enough in my head, but couldn't at all express it at once in correct or fluent English, and I don't know that a dictionary would have helped me much. It was more the turn of the phrase and a peculiar form of expression. Sunday, February 21, 1892.
