THE Houses of Parliament, in their present form, are less than a century old, nearly the whole of the Palace of Westminster having been destroyed in the fire of 1834. But such buildings age quickly, and even the new Houses teem with history, custom and tradition, whilst Westminster Hall is, of course, the original scat of the Courts of Justice of the realm. Sir Ernest Gray has had very great experience of conducting parties through the House of Commons -of which he was a Member for four years-and this will certainly not be the least interesting of his series of talks.
