Illuminations for Peace -- Ovation to Louis XVIII. -- His departure for France -- Peace with France -- Cheaper provisions -- Distinguished foreign guests in London -- Arrival of Emperor of Russia and King of Prussia -- Movements of the great folk -- Popularity of General Blücher. Easter Monday fell on the 11th of April, and on that day London was brilliantly illuminated, very much better than usual; but then lights and transparencies had only been, hitherto, used for Victories--this was for PEACE, which was welcomed by all with heartfelt thankfulness. The Duchess of Oldenburgh, at the Pulteney Hotel, had "THANKS BE TO GOD" in variegated lamps. The Duke of Northumberland wreathed the head of his immortal lion with laurels; the statue of King Charles I. close by, was covered with laurels. Carlton House had its pillars entwined with lamps, the entablature marked out with them. On the parapet were six large stars; in the centre were the Arms of France supported by the figure of Fame with laurels, under which was Louis XVIII. A pedestal of fire supported two large stars: on the left, were Russia and Austria; on the right, Prussia and England; whilst in the centre, was a bit of deliciously bad French--"_Vive_ LES BOURBONS," all done in silver lamps. I have but space to mention one more, and that is Ackermann's in the Strand, which was, if possible, more emblematical than usual. It is thus described: "A Transparency: The Tyrant Corsican is attacked by Death under the walls of Paris; the grisly Monarch has placed his foot upon his breast, and holds in one hand an hour-glass, which, almost expended, leaves him just time enough to reflect upon the murders and other atrocities which have attended his wicked Career. The other hand grasps a massive iron spear, with which he is supposed to have been dealing out destruction among the armies of Bonaparte. The fallen Tyrant, in an attitude of terror, supplicates Death to arrest his fatal purpose. Beneath him are broken eagles, torn National Flags, &c., and in his hand he grasps the shattered bloody remains of a sword. On the Walls of Paris are seen Cossacks, and other Russians, Prussians, Austrians, &c., who are raising the standard of the Bourbons. This transparency was surmounted by a brilliant circle of gas-lights, indicative of the union of the world in the Holy Cause; over this circle was a large white flag spotted with _fleurs de lys_, hung out in triumphant display over the tattered, debased, tricoloured banner of the Revolution. On each side of the principal transparency was a smaller one; the first representing Bonaparte blowing bubbles, which burst as fast as created: in the other, he was seen amusing himself with building houses and Castles of Cards, which, tumbling down as fast as they are put up, are truly emblematic of the vast achievements of his reign: a bottle under the table indicative that all his designs have ended
