At the Guildhall, Mr Monkey went into the Clock Museum, where he saw all sorts of clocks and watches. He was impressed with a strange clock that works by rolling a brass ball down a slope. He thought the watch in a little silver skull that was allegedly given to Mary, Queen of Scots, was interesting, until he found out that the skull was made in the 19th century. He also admired the replica of H1, John Harrison's first Marine Clock.
There's a page about the museum at the Corporation of London website, and another at the website of The Worshipful Company of Clockmakers of London.
