Description/Abstract | In an attempt to detect fine dust from the Perseid meteor shower, magnetic particles were collected during August 1957 and 1958 by observers in Great Britain and Greenland. Many of these particles were collected directly from the air by greased slides attached to aircraft and by placing bowls of filtered water in isolated places. However, a vast number appeared in chimney ash, and some doubt exists concerning their origin. The majority of these particles were black or silvery in color and averaged about 5O mu in diameter. Examinations indicate that many of them were metallic iron with traces of copper. The strongest argument in favor of an extraterrestrial origin was the detection of nickel in particles that were collected during August 1958 at the south-west tip of St. Agnes, Isles of Scilly.
