Browning (Robert) Autograph letter signed ('Robert Browning') to Mrs Millais, reading "I don't know what my writing never so much fiction has to do with preventing me from saying a true word now and then, such as this, that I am greatly obliged to you for all your kindness. I and my sister went to the portrait gallery yesterday, and had a couple of calls in your neighbourhood; it seemed natural to call on you [...] never mind, we shall try again before we go away. I was sole cavalier to two ladies at the Opera, could not leave them for a minute. I liked the four acts that I heard, having been whisked away as the fifth began", one page, integral blank, mailing folds, light foxing and age-related toning, remnants of previous mount, 8vo, 9 Warwick Crescent, 18 July 1867, with original mailing envelope addressed in Browning's hand.
