Abstract
This paper is a discussion of W. J. Thomsen's prize-winning paper presented to the Geology Section of the Iowa Academy of Science in 1952 and entitled "The Annual Contribution of Meteoritic Dust to the Mass of the Earth" (1). The present paper presents evidence that Thomsen's unusually high estimate for the annual deposition of meteoritic dust may be due to the presence of fly-ash in the magnetic dust samples he collected.
