They are the only descriptive and critical art guides in existence. They are written by the high authority on art, who is probably better acquainted than any other writer living with the European galleries. They are composed of clear, pointed critical notes upon individual pictures, written before those pictures by the author. These notes deal comprehensively with practically all of the European galleries; and therefore discuss and explain practically all the important paintings that hang in those galleries. The volumes are so manufactured as to be easily carried, and they combine perfectly the qualities of beauty and durability. The Volumes I. LONDON--National Gallery, Wallace Collection.
