_Paris, July 6th._--I went yesterday to the Exhibition in the morning; then to Notre Dame and the Luxembourg Gardens and drove about Paris; dined _en trio_ with Madame de Lieven and Guizot, when there was of course nothing but political talk. Guizot thinks there has been not only a series of diplomatic blunders, but a wonderful want of _invention_, not to strike out some means of adjusting this quarrel, in which I agree with him. This morning Labouchere and I went to Versailles. Fould had given me a letter to the Director of the Museum there, M. Soulié, whom we found very intelligent, well informed, and obliging. We told him our object was to avoid the _giro regolare_ of the endless rooms fitted up with bad pictures by Louis Philippe, and to see the apartments full of historical associations from the time of Louis XIV. down to the Revolution. We were completely gratified, and he took us over everything we wished to see, being admirably qualified as a cicerone by his familiarity with the localities and the history belonging to them. We saw all the apartments in which Louis XIV. lived, and what remains of those of Madame de Maintenon. The Palace has been so tumbled about at different times, and such alterations made in it, that it is not always easy to ascertain correctly where the rooms of certain personages were, but our guide proved to our complete satisfaction that certain rooms he showed us were those which really did belong to Madame de Maintenon. We saw too in minute detail the apartments of Louis XVI. and Marie Antoinette, and the passages through which she fled to escape from the irruption of the mob on the 5th of October. The whole thing was as interesting as possible. LORD JOHN RUSSELL'S RETURN.
