Preliminary charts are presented based on two years of data, to demonstrate the geographic distribution over Sweden of the annual amounts of Na, Cl, K, Ca, NH 3 -N and NO 3 -N brought to the surface of the earth by precipitation. The ratios of these total amounts to the total amounts of Na deposited during the same time interval are shown to possess systematic geographic distribution patterns. Comparisons are made between these ratios and the corresponding quantities in sea water. The investigation is now being resumed to provide additional data from a larger number of stations and for longer time periods. DOI: 10.1111/j.2153-3490.1954.tb01121.x
