In Holland at The Hague there are four Vermeers: The Toilette of Diana, the Head of a Young Girl, An Allegory of the New Testament, and the View of Delft. At the Rijks Museum, Amsterdam, there are four: The Milk Girl, The Reader, The Letter, and A Street in Delft. (This latter is the House in Delft, which sold for seventy-two florins in 1696.) In Great Britain in the Coats collection at Castle Skalmorlie (Scotland) there is Christ at the House of Martha and Mary. In the National Gallery, a young woman standing in front of her clavecin. In the Beit collection, London, a young woman at her clavecin. Collection Salting, London, The Pianist. Windsor Castle, The Music Lesson. Beit collection, A Young Woman Writing. In the Joseph collection, A Soldier and a Laughing Girl. And the Sleeping Servant, formerly of the Kann collection, Paris, then in London, and later sold to Mr. Altman. In Germany we find the following: At the Berlin Museum, The Pearl Collar. The Drop of Wine, in the same museum, Berlin. The Coquette, Brunswick Museum. The Lady and Her Servant, in the private collection of James Simon, Berlin. The Merry Company and The Reader in the Dresden gallery. The Geographer at the Window, in the Staedel Institute, Frankfort. In France, The Astronomer of the A. de Rothschild collection at Paris, and the little Lacemaker, in the Louvre Gallery. In Belgium, there was at Brussels the portrait of a girl, which was formerly in the Arenberg gallery. When I tried to see it I was told that it had been sold to some one in Germany. Its type, judging from the head of a girl at The Hague, is not unlike The Geographer, in the collection of Viscount Du Bus de Gisegnies, Brussels. A Young Girl, collection of Jonkheer de Grez, Brussels. This last was discovered by Doctor Bredius in 1906, and is at the present writing in New York at the gallery of Mr. Knoedler. In Austria-Hungary there are two noble Vermeers; one in the private gallery of Count Czernin, the portrait of the painter, the other in the Museum of Budapest, the portrait of a woman, the latter as solidly modelled as any Hals I ever viewed. The Czernin Vermeer is the only one in Vienna (the other Vermeer in this gallery is by Renesse). It is a masterpiece. In it he grazes perfection. The United States is, considering the brevity of the list, well off in Vermeers. There is at Philadelphia the Mandoliniste of John G. Johnson (without doubt, as M. Vanzype points out, the Young Woman Playing the Guitar of the 1696 sale). At Boston Mrs. John Gardner owns The Concert. At the Metropolitan Museum there is the Woman with the Jug (Marquand); and the Morgan Letter Writer; H. C. Frick boasts The Singing Lesson (probably known at the 1696 sale as A Gentleman and Young Lady Making Music).
