Abstract
NORDENSKJÖLD collected and described three different kinds of dust, one consisted of diatoms, a second of a siliceous and apparently felspathic sand, both from the surface of the ice in Greenland; while a third consisted of sooty-looking particles composed of elements invariably associated with iron meteorites and of uncommon occurrence in terrestrial matter, namely, besides metallic iron, cobalt, nickel, carbon, silicon and phosphorus. He concluded that it was meteoric matter showered down upon the earth, and that cosmic dust is falling imperceptibly and continually.
