Dr. CHESTER A. REEDS gives in Bull. Amer. Mus. Nat. Hist. (1937) a detailed catalogue of the meteorites contained in this collection, which in 1935 was transferred from the Department of Geology to that of Astronomy, and is now housed in the new planetarium building. The previous catalogue, by Dr. E. O. Hovey in 1896, showed 45 specimens representing twenty-six falls. The collection now contains 3,744 specimens, representing 546 of the 1,073 falls known to the end of the year 1935. The large number of specimens is partly accounted for by 2,129 stones, ranging in weight from 0·2 to 6,650 grams, from the Holbrook, Arizona, shower of 1912. Notable masses are the three Cape York, Greenland, siderites, the largest of which weighs 36½ tons, that is, short tons of 2,000 lb., and is by far the largest meteorite preserved in a museum ; and the Willemette, Oregon, siderite of 14·2 metric tons. Much of the general information in the catalogue, even that relating to American meteorites, is reproduced word for word from the late Dr. G. T. Prior's British Museum catalogue.
