Abstract
A YEAR-LONG programme involving daily collections of atmospheric dust at several widely separated, isolated sites has been undertaken with the object of identifying particles that may be of extra-terrestrial origin. The particles in question are opaque, shiny spherules with diameters less than 10 microns. They appear to be of a nature entirely different from that of the larger spheres abounding in densely populated areas. Their meteoritic nature is suggested by the fact that the rate of fall and the frequency distribution with size of these particles have been found to be the same at the various stations.
