So far as I know, there has never yet been compiled, for the illustration of any collection of paintings whatever, a series of notes at once so copious, carefully chosen, and usefully arranged, as this which has been prepared, by the industry and good sense of Mr. Edward T. Cook, to be our companion through the magnificent rooms of our own National Gallery; without question now the most important collection of paintings in Europe for the purposes of the general student. Of course the Florentine School must always be studied in Florence, the Dutch in Holland, and the Roman in Rome; but to obtain a clear knowledge of their relations to each other, and compare with the best advantage the characters in which they severally excel, the thoughtful scholars of any foreign country ought now to become pilgrims to the Dome—(such as it is)—of Trafalgar Square.
