RESEARCH ON METEORIC DUST FALL OUT.
Abstract
Starting May 1st 1962 every day the number of particles of meteoric dust falling on a plate of 60 x 60 cm and also on a plate of 40 x 40 cm was counted. Not only were the numbers of particles counted, but also the dimensions of each particle were measured. The particles not only differ in size but also in shape. As yet it cannot be said whether or not these differ ences in shape have any significance. Only by continuous observation and by a subsequent statistical discussion will it later on be possible to clarify this point. Up till now about 40,000 different particles have been meas ured of which the dimensions range from around 10 micron to 100 micron. Some particles are visible even by the naked eye. The particles are collected with the help of an electromagnet. Therefore it is obvious that only the ''rest masses'' of iron meteorites are collected. Consequently, also all discussions concerning the observed particles exclusively apply to iron meteorites. (Author)
