Oesophagus

No idea what the title of the book is, but it's a wonderful picture. Had a couple of hours in London on the way home, so we went to the Idea Store (library) in Whitechapel, Tower Hamlets. Wonderful, very busy library including books, DVDs, newspapers etc., teaching rooms, sofas, an electric piano to practice on, computers, a community police officer and a Malaysian cafe. The street outside was also thronging with market stalls and people going in and out of the tube station. Very enjoyable break on the journey. On to Brussels this evening and then home tomorrow.
