[New Ywk Timex, May 13.] This week an Emperor of Russia is once more to become a guest of England. It is thirty years since his father trod the

halls of Queen Victoria, just two months before the present Czar's Bon-in-law was born. The circumstance brings home to tho mind the extraordinary length of her Majesty's reign, and the huge volume of history which has been accumulating since the magnificent form of Nicholas, tower ing above all around him, was seen enter ing the hall of Buckingham Palace, where his salute to his hostess was ao hearty as to be distinctly heard at the furthest corner of the spacious apartment, and drew a smile from tho maids of honor. Of all the monarchs reigning on that day m June, 1844, the Queen- of England is tho sole survivor. Even Pius IX. was then but a cardinal. Of the Cabinet of England at that time, two members alone survive — the Duke of Buccleuch. and Mr Gladstone ; and time's changes are here again curiously conspicuous, for Mr Glad stone was then the colleague of those thorough-going Tories, Lord Lyndhurst, the Duke of Wellington, and (the late) Lord Derby, under Sir Robert Peel. In France, Louis Philippe,' four years later a fugitive as Mr Smith, seemed then com paratively settled. Frederick William was reigning at Berlin, and a few months later nearly lost his life at the hands of an- assassin. Bismarck was chiefly known to fame as what the Parisians call a gay liver, and Bun sen's dream of a united Germany seemed distant indeed. Italy has beon turned topsy-turvy since then. The Kingdom of Naples, the Grand Duchies of Tuscany, Parma, andModena, the Papal States, have been wiped off the map. The quiet Prince William, who was Bunsen's guest m London m the August of that same year, and to whose military questions we are told that the Duke of Wellington "readily replied," has more than realised the dreams of his diplomatic philosopher host — who, it seems curious to think, was at the outset of his career Mr W. B. Astor's tutor — for he is now Emperor of Germany. Peihaps the counsels of the warrior duke may not have been without a bearing on the issue of that summer day at Sedan four years ago.
