The SKETCH-GALLERY, which, as we have said, occupies the south and a part of the west side, contains perhaps the most choice and extensive collection of original drawings by the old masters in any private collection, embracing the Italian, French, Flemish, Venetian, Spanish, and other schools; and containing matchless examples of Raffaelle, Michael Angelo, Albert Dürer, Titian, Rembrandt, Rubens, Leonardo da Vinci, Poussin, Claude, Salvator Rosa, Correggio, Luca Signorelli, Andrea del Sarto, Lo Spagna, Giulio Romano, Caravaggio, Zucchero, Andrea Mantegna, Parmigiano, Giorgione, Giulio Campagnola, Paul Veronese, the Carracci, Guido Reni, Domenichino, Guercino, Holbein, Lucas Cranach, Lucas Van Leyden, Vandyke, Van der Velde, Jan Miel, and indeed of almost every well-known name. The collection was formed by the second Duke of Devonshire at considerable cost; the nucleus being purchased at Rotterdam. Among those by Michael Angelo are a study for the ceiling of the Sistine Chapel; some spirited studies of figures for the same ceiling; and a Virgin and Child. By Leonardo da Vinci a fine head of the Virgin.

By Holbein, some of the finest known examples, including “the Fall of Phaeton,” “the Last Judgment,” “Hagar and Ishmael,” “Diana and Actæon,” and others. By Albert Dürer several fine examples. Altogether the collection is the most remarkable in any mansion.

These were, in great measure, removed here from the Duke’s villa at Chiswick. Adjoining this, at the south-west angles, is—
