We have had to wait four years for the concluding volumes of _The Life of Benjamin Disraeli_ (MURRAY), but, as the engaged couple said of the tunnel, "it was worth it," for in the interval Mr. BUCKLE has been able to enrich his work with a wealth of new material. This includes DISRAELI'S correspondence with QUEEN VICTORIA during his two Premierships, and the still more remarkable letters that he wrote to the two favoured sisters, ANNE, Lady CHESTERFIELD, and SELINA, Lady BRADFORD, during the last eight years of his life. To one or other of them he wrote almost every day, and from the sixteen hundred letters that have been preserved Mr. BUCKLE has selected with happy discretion a multitude of passages which throw a vivid light upon the political events of the time and upon DISRAELI'S own character. Whereas the first four volumes of the biography might be likened to a good sound Burgundy, thanks to these letters the last two sparkle and stimulate like a vintage champagne. As we read them we seem to be present at the scenes described, to overhear the discussions at the Cabinet, to catch a glimpse of the actors _en deshabille_. Mr. BUCKLE says that "Disraeli, from first to last, regarded his life as a brightly tinted romance, with himself as hero." In one of his letters to Lady BRADFORD he says, "I live for Power and the Affections." A poseur, no doubt, he was, but not a charlatan. His industry was amazing and his insight almost uncanny. "I know not why Japan should not become the Sardinia of the Mongolian East," he writes in 1875. To the political student these Volumes will be almost as fruitful a field as BURKE; for myself, I have found them more fascinating than any novel. * * * * *
