Yesterday being my birthday & a clear bright day into the bargain showing many green & yellow flushes on the trees, I went to South Kensington & heard Mozart & Beethoven.  I don' t think I did hear very much of them, seated as I was between Katie and Elena, & pitched headforemost into outrageous banter of the usual kind with the Countess.  But the Countess was very affable & jolly, invited me indeed insisted upon my coming, to tea with her. We turned our money under the new moon.  She vibrated under the pleasure of a compliment - 'when Lady Cromer's there one feels & c &c -' a compliment to her beauty. But the room was clamorous with South Kensington.
