Report from the March 14, 1920 issue of Nature

During a heavy thunderstorm which ensued on Monday, March 4, [1920] between 2:30 p.m. and 4.15 p.m., an aerolite was observed to fall at Conleny Heath, near St. Albans. The observed who has placed the specimen in my hands for examination, stated that the stone fell within a few feet from where he was standing, and that it entered the ground for a distance of about 3 feet. Its fall was accompanied by an unusually heavy clap of thunder. The example weighs 5 pounds 14 1/2 ounces and measures 6 3/4 inches by 5-5/8 inches at its great length and breadth respectively. The mass is irregularly ovate on the one side, and broken in outline on the other. The actual surface throughout is fairly deeply pitted, and under magnification exhibits the usual chondritic structure of the crystalline matter with interspersed particles of what appears to be nickeliferous iron.
The author of the report, G.E. Bullen, submitted the stone to the British Museum where it was examined and determined not to be of meteorite origin.
