The mineralogical department of the Peabody Museum at Yale has recently received a very important addition, through the gift of a large collection of meteorites by Mr. and Mrs. Henry F. English of New Haven. These specimens fell in Winnebago county, Iowa, on May 2, 1890, and are probably the largest collection from any single fall in the world. Nearly all are perfect specimens, being completely covered with a black, burnt coating due to their coming so rapidly through the atmosphere. Several show fractures, and others are thoroughly rounded and melted off. The collection is considered to be a very valuable addition to the museum.
