TRANSLATOR'S NOTE As in the first and second volumes, the translator has, from personal observation, or with the assistance of others, been able to amplify the descriptions of a number of pictures in British collections, and to note, either in the text or in the index, changes of ownership that have occurred since the German text was printed. Encouraged by the approval bestowed upon the index of painters and engravers which he added to the second volume, the translator has compiled a similar index for this volume. The translator has to express his gratitude to Sir Charles Holroyd, Director of the National Gallery ; to Mr. Edward Robinson, Assistant Director of the Metropolitan Museum, New York ; and to Mr. D. S. Meldrum, among others, for their courteous advice and assistance in the preparation of this volume. EDWARD G. HAWKE. IX
