_Sunday, May 28._ Ever since my last date I have been delivering letters, and attending the meetings of different societies. One evening was spent at the Royal Society, where, as in all Royal Societies, I heard a dull, heavy lecture. Yesterday my first call was on Sir Thos. Lawrence; it was half-past eight, as I was assured later would not do. I gave my name, and in a moment the servant returned and led me to him. I was a little surprised to see him dressed as for the whole day. He rose and shook hands with me the moment I pronounced my good friend Sully's name. While he read deliberately the two letters I had brought, I examined his face; it did not exhibit the look of genius that one is always expecting to meet with in a man of his superior talents; he looked pale and pensive. He wished much to see my drawings, and appointed Thursday at eight of the morning, when, knowing the value of his time, I retired. Several persons came to see me or my drawings, among others Mr. Gallatin, the American minister. I went to Covent Garden Theatre with Mr. Bentley in the evening, as he had an admittance ticket. The theatre opens at six, and orders are not good after seven. I saw Madame Vestris; she sings middling well, but not so well in my opinion as Miss Neville in Edinburgh. The four brothers Hermann I admired very much; their voices sounded like four flutes. _May 29._ I have been about indeed like a post-boy, taking letters everywhere. In the evening I went to the Athenaeum at the corner of Waterloo Place, expecting to meet Sir Thomas Lawrence and other gentlemen; but I was assured that about eleven or half-past was the fashionable time for these gentlemen to assemble; so I returned to my rooms, being worn out; for I must have walked forty miles on these hard pavements, from Idol Lane to Grosvenor Square, and across in many different directions, all equally far apart.
