AN AMERICAN PITT-RIVERS MUSEUM.—The famous ethnological collection made by General Pitt-Rivers first became known to students when it was exhibited at the Bethnal Green Museum in 1874–75. In 1883 it was presented to the University of Oxford, and since then, under the direction of Mr. Henry Balfour, its value has greatly increased. The distinguishing feature of this museum is that the exhibits are arranged, not in geographical or racial order, but in series illustrating the evolution of the chief human inventions. A collection of the same kind was made by the authorities of the United States National Museum for the Trans-Mississippi Exhibition held at Omaha in 1898, and since then it has been developed by distinguished anthropologists like Mason, Holmes, and Walter Hough, the author of an interesting pamphlet discussing it, entitled “Synoptic Series of Objects in the United States National Museum illustrating the History of Inventions.” This pamphlet describes, with a good series of illustrations, the chief inventions in the order of their development—fire-making, torches and candles, lamps, cooking utensils, knives and forks, and so on; The vast resources of the American collections have produced a fine series of examples. The present pamphlet, adapted to our collections, might well serve as the basis for a popular manual of ethnology.
