Based on the analysis of observations and experimental data on the influx of space bodies on the Earth in a small interval of masses, an average integral function of bodies (particles) is obtained for a wide interval of masses from 10^-12 to 10²² g. This dependence is compared with the similar one obtained on the basis of other data where the masses range from 10^-18 to 10¹⁸ g. It is the author's opinion that this discordance of the functions and somewhat different conclusions can be attributed to more accurate recent data. This is confirmed by some studies where the differences of particle fluxes for the same masses reach several orders of magnitude.
